  • 00:00Gives me,
  • 00:02exceptional joy to be able
  • 00:04to introduce,
  • 00:05Anne Partridge.
  • 00:08Anne,
  • 00:10and I have known each
  • 00:11other a long time,
  • 00:13And I won't say exactly
  • 00:15how long, but
  • 00:17since she was a second
  • 00:19year fellow,
  • 00:20we've known one another and
  • 00:22worked together very closely
  • 00:25at, Dana Farber for years
  • 00:27and years and years.
  • 00:30And she is still the
  • 00:31person who I speak to
  • 00:32most regularly at Dana Farber,
  • 00:35which used to be once
  • 00:37a week, but is now
  • 00:39a little less as she's
  • 00:40become even more busy.
  • 00:44So Anne is a health
  • 00:45services researcher,
  • 00:47has focused on
  • 00:49the care
  • 00:50of
  • 00:51young women with breast cancer,
  • 00:54on survivorship,
  • 00:56on a whole range of
  • 00:57other issues. One of the
  • 00:59first things we ever did
  • 01:00together was look at
  • 01:02giving results back to clinical
  • 01:04trial participants
  • 01:06and had a whole series
  • 01:07of papers
  • 01:08back.
  • 01:09Oh my god, in the,
  • 01:11early two thousands about that
  • 01:14particular topic.
  • 01:17Anne is the interim chair
  • 01:19of medical oncology at Dana
  • 01:21Farber and has been for
  • 01:22the past couple of months.
  • 01:25She
  • 01:26is on the ASCO board,
  • 01:29is the
  • 01:30one of two chief scientific
  • 01:32advisers
  • 01:33for Komen,
  • 01:35and is the cochair of
  • 01:37the Alliance Breast Committee among
  • 01:39other things. And I just
  • 01:40calculated up that she has,
  • 01:41like, two hundred percent effort.
  • 01:44She also is perhaps the
  • 01:47only person in the world
  • 01:48who could tolerate something that
  • 01:50I find very embarrassing, and
  • 01:52she doesn't somehow,
  • 01:54which is that she actually
  • 01:56occupies the Eric p Weiner
  • 01:58chair in breast cancer research
  • 01:59at Dana Farber,
  • 02:01which is an an an
  • 02:02embarrassment
  • 02:03to me
  • 02:04that my name is on
  • 02:05such a thing. But,
  • 02:07again,
  • 02:08Anne is perhaps my only
  • 02:10friend who could
  • 02:12or colleague who could ever
  • 02:13tolerate being in that, particular,
  • 02:17chair.
  • 02:18So, Anne, it is a
  • 02:20true pleasure having you here
  • 02:22today.
  • 02:23I know everyone you've met
  • 02:24with has had a really
  • 02:26wonderful time meeting with you,
  • 02:28and,
  • 02:29we look forward to your
  • 02:30talk, Breast Cancer in Young
  • 02:32Women, Optimizing Knowledge and Care
  • 02:34to Improve Outcomes. Oh, and
  • 02:35before you start talking, I'm
  • 02:37gonna present you
  • 02:39with the,
  • 02:41Yale Cancer Center Grand Rounds
  • 02:43Patricia
  • 02:44Kingsbury lecture.
  • 02:46Why?
  • 03:03Alright. So it is it
  • 03:04is really a joy to
  • 03:06be here today and no.
  • 03:09And,
  • 03:10to talk with all of
  • 03:11you about this.
  • 03:12I, as you heard from
  • 03:14Eric, I I feel very
  • 03:15at home here since, many
  • 03:18since Eric's here and and
  • 03:19many of my former colleagues.
  • 03:20And, of course, I've
  • 03:22gotten to know many people
  • 03:24who were either here or
  • 03:25elsewhere before here
  • 03:26over the years and and
  • 03:28had many wonderful collaborations
  • 03:30and that continue on to
  • 03:31today.
  • 03:32I'm gonna focus on, kind
  • 03:34of the thing that I
  • 03:35eventually landed on
  • 03:38during my career to focus,
  • 03:40the my, you know, kind
  • 03:41of
  • 03:42research and clinical efforts
  • 03:44such that I could try
  • 03:45to, you know, make a
  • 03:46little dent in the world.
  • 03:48And as you heard, I
  • 03:49I've known Eric a long
  • 03:50time.
  • 03:51And, you know, one of
  • 03:52the reasons that,
  • 03:54beyond the teams that we've
  • 03:55built, that we've started to
  • 03:57make a little dent in
  • 03:58the world is because I
  • 03:59was in a place with
  • 04:00a mentorship that was just
  • 04:01so supportive
  • 04:03of of the kind of
  • 04:04work that I'm gonna talk
  • 04:05about. So I'm I'm really
  • 04:06forever grateful of that.
  • 04:09So let's start with some
  • 04:10basic facts around
  • 04:13we're gonna talk about breast
  • 04:14cancer in young women, but
  • 04:15how how do we get
  • 04:16there? Well, first, I think
  • 04:17there needs to be a
  • 04:18recognition
  • 04:20that, fortunately,
  • 04:21at least as of twenty
  • 04:22twenty four, while we still
  • 04:24have far to go,
  • 04:26the
  • 04:27now about, you know, just
  • 04:28over a majority of people
  • 04:30diagnosed with cancer
  • 04:32will
  • 04:33be long term survivors.
  • 04:35So we are getting better
  • 04:37and better at both diagnosing
  • 04:39early, and you could even
  • 04:40argue some some diseases overdiagnosing
  • 04:43and treating, in particular, around
  • 04:45breast cancer,
  • 04:47our cancers and creating survivors,
  • 04:50which is a, you know,
  • 04:51good problem to have. We
  • 04:52wanted more and more survivors,
  • 04:54and I just had the
  • 04:55the, joy of meeting with
  • 04:56Tara Santa and her crew
  • 04:58about the survivorship work you've
  • 04:59got going on here, which
  • 05:00is terrific.
  • 05:01And breast is one of
  • 05:03the biggest groups as you
  • 05:04can see, and we all
  • 05:05know this clinically
  • 05:06of survivors,
  • 05:09because, you know, most women
  • 05:10and some men will will
  • 05:12develop breast cancer, but those
  • 05:13who develop breast cancer
  • 05:15will be long term survivors,
  • 05:17even, you know, moving more
  • 05:18towards long term survivors with
  • 05:20metastatic disease, thanks to many
  • 05:22of the breakthroughs. So when
  • 05:23I speak about survivorship, I'm
  • 05:24speaking about kind of the
  • 05:26global survivorship
  • 05:27of for many
  • 05:29issues. But particularly with young
  • 05:30women, even with metastatic disease,
  • 05:33we're now seeing different subtypes
  • 05:34living out, you know, five,
  • 05:36ten, fifteen years and beyond
  • 05:38more so than we did
  • 05:40previously. So we need to
  • 05:41make sure we incorporate them
  • 05:42as well because they're not
  • 05:44dying of other things, fortunately.
  • 05:46And yet when we think
  • 05:48about young women, and this
  • 05:49is one of the things
  • 05:49that kind of really got
  • 05:51me paying attention when I
  • 05:52was that second year fellow
  • 05:54working in Eric's clinic, is
  • 05:55that, you know, even though
  • 05:57the majority will be survivors,
  • 05:59you can see the y
  • 06:00axis on this curve on
  • 06:01the on that's in the
  • 06:02center of the slide.
  • 06:04It starts at zero and
  • 06:05goes up to ten to
  • 06:06fifteen percent.
  • 06:07The youngest women actually had
  • 06:09the highest risk of recurrence
  • 06:11and mortality
  • 06:12from breast
  • 06:13cancer. Theirs had similar,
  • 06:16cancer specific death rates as
  • 06:18the oldest women. And these
  • 06:20are recent data where we've
  • 06:21now incorporated,
  • 06:23you know, HER2
  • 06:25positivity or negativity
  • 06:27into our national dataset.
  • 06:29And there's a five percent
  • 06:31difference
  • 06:32where the oldest and the
  • 06:33youngest
  • 06:34have the worst mortality outcomes,
  • 06:38in breast cancer.
  • 06:39And so, you know, what's
  • 06:40going on there and what
  • 06:41can we do to mitigate
  • 06:42that has been something that
  • 06:44that many of us have
  • 06:45focused on.
  • 06:46We also know, and these
  • 06:48are some of the latest
  • 06:49data
  • 06:50from the CANTO cohort, which
  • 06:51is a prospective cohort of
  • 06:54of cancer survivors now breast
  • 06:56and, I think, lung cancer
  • 06:57in France, population essentially population
  • 07:00based. It's in many, hospitals
  • 07:02in France.
  • 07:03And we know that young
  • 07:04age
  • 07:05of breast cancer is also
  • 07:06associated with a worsening quality
  • 07:09of life trajectory. You can
  • 07:10see that as ones in
  • 07:11the red, whether they either
  • 07:12start bad, but especially those
  • 07:14that started out kind of
  • 07:15okay and then come down.
  • 07:17The clinical characteristics
  • 07:19associated with being part of
  • 07:20that trajectory
  • 07:21include being younger
  • 07:23and other things that are
  • 07:24related to being younger. And
  • 07:26so not only are young
  • 07:27women stuck with the risk
  • 07:29of, you know, higher risk
  • 07:30of recurrence
  • 07:31and warranting more treatment, but
  • 07:33they're also
  • 07:34in part related to that,
  • 07:36have a worse psychosocial
  • 07:37trajectory
  • 07:39after their diagnosis and well
  • 07:40into survivorship
  • 07:41that's been well documented.
  • 07:43So I I think, you
  • 07:45know, hopefully, I've just shown
  • 07:46you that breast cancer and
  • 07:47anybody who cares for these
  • 07:48patients and our young patients
  • 07:49is just more complicated.
  • 07:51This is true of pretty
  • 07:52much all of the AYA
  • 07:53cancers.
  • 07:55And and one of the
  • 07:56reasons that it's complicated is
  • 07:57because they're not only dealing
  • 07:58with the decisions around
  • 08:00chemotherapy, endocrine therapy, local therapy
  • 08:02that you can see on
  • 08:03the top of this slide,
  • 08:04which are, you know, hard
  • 08:06decisions when they are decisions
  • 08:08and made even harder sometimes
  • 08:10by where young people are
  • 08:11in their lives,
  • 08:13and especially if they have
  • 08:14more aggressive disease, which warrant
  • 08:15more of these things often.
  • 08:17But they suffer from making
  • 08:19the decisions around everything else
  • 08:20you see around that diagram,
  • 08:22you know,
  • 08:23not the least of which
  • 08:24is fertility and the idea
  • 08:26of premature menopause,
  • 08:28the role functioning at a
  • 08:29time in one's life when
  • 08:30they're earlier either in their
  • 08:32partnership, their careers, or may
  • 08:35not be done with school,
  • 08:37sexual health and body image,
  • 08:38something that's not unique to
  • 08:40young onset cancers, but is
  • 08:42certainly accentuated
  • 08:44by being young. And then
  • 08:45the genetics of young onset
  • 08:47cancers plays in, of course,
  • 08:49in,
  • 08:50more so for younger patients.
  • 08:51And that all contributes to
  • 08:53their psychosocial health and functioning,
  • 08:56which can when one of
  • 08:57the reasons we see,
  • 08:58things going south for our
  • 09:00youngest patients and therefore, perhaps
  • 09:02need to be focusing more
  • 09:03on them as I know
  • 09:03you guys are doing too.
  • 09:06So now a few years
  • 09:07ago, a group of us
  • 09:09got together with the Young
  • 09:10Survival Coalition, an advocacy group
  • 09:12based in New York but
  • 09:13international
  • 09:14that focuses on young onset
  • 09:16breast cancer and said, okay.
  • 09:18What are our research priorities?
  • 09:20What do we really wanna
  • 09:21focus on recognizing we can't
  • 09:22focus on everything?
  • 09:24And the group came up
  • 09:25with, you know, a pretty
  • 09:26overarching,
  • 09:28broad set of priorities,
  • 09:30and you can see them
  • 09:31listed here. I'm gonna focus
  • 09:32on a few recent data
  • 09:34around treatment,
  • 09:35fertility, and then the overarching
  • 09:37quality of life and survivorship,
  • 09:39now. But I I do
  • 09:41think this that that piece
  • 09:42is nice if anybody's focusing
  • 09:44on AYA's because it does
  • 09:45get at the things that
  • 09:46we heard from our the
  • 09:47patients and advocates,
  • 09:49what's important to them, and
  • 09:50it and, obviously, it was
  • 09:51consistent with what was important
  • 09:53to the the,
  • 09:55the,
  • 09:56researchers in the room as
  • 09:57well.
  • 09:58One of the things that
  • 09:59we also did at Dana
  • 10:00Farber now
  • 10:02almost twenty years ago
  • 10:04was to recognize
  • 10:05that
  • 10:06there were not great datasets
  • 10:09for our youngest patients with
  • 10:10either enough young patients. So
  • 10:12clinical trials are very well
  • 10:14annotated.
  • 10:16Big cohorts very well annotated
  • 10:18like nurses health study and
  • 10:19women women's health initiative.
  • 10:21But the young women who
  • 10:22go on to get breast
  • 10:23cancer in the clinical trials,
  • 10:25just the proportion of young
  • 10:26women, even though they participate
  • 10:28in trials as much if
  • 10:29not more than anybody else,
  • 10:30the absolute numbers
  • 10:32are fairly small.
  • 10:34And so there were very
  • 10:35few place. And, you know,
  • 10:36if you look at SEER
  • 10:36data, it's great for big
  • 10:38thirty thousand foot views, but
  • 10:39very little granularity, especially when
  • 10:41we first started looking into
  • 10:42the issues very early as
  • 10:43a young woman. And so
  • 10:45we realized that we just
  • 10:46didn't have a place to
  • 10:47get many of the answers
  • 10:48that we needed. And so,
  • 10:50fortunately, again, I was supported,
  • 10:52in large part by Eric
  • 10:54and others at Dana Farber
  • 10:56to create a cohort,
  • 10:57to look at our young
  • 10:58patients over time. And we
  • 11:00called it, the helping ourselves,
  • 11:02helping others
  • 11:04study, which, of course, at
  • 11:05Christmas is ho ho, which,
  • 11:07you know, it's a little
  • 11:08bit regretful.
  • 11:09But it was with the
  • 11:10idea that I think I
  • 11:12was young at the time
  • 11:13and thought that, you know,
  • 11:14maybe I was gonna get
  • 11:14breast cancer soon. It's one
  • 11:16good thing to age out
  • 11:17of that. And young the
  • 11:18Young Women's Breast Cancer Study
  • 11:20is something that we've now
  • 11:21been running for almost twenty
  • 11:22years,
  • 11:23and it's a prospective cohort
  • 11:25that, we said every woman
  • 11:27forty and under at twelve
  • 11:28hospitals
  • 11:30in mostly Eastern Massachusetts, but
  • 11:32we also, roped in folks
  • 11:33in Colorado and Minnesota
  • 11:36and in Toronto.
  • 11:38And we've been following them,
  • 11:40and we collected a lot
  • 11:41of data over time, and
  • 11:42we're still doing it. So
  • 11:44focusing on disease and tumor
  • 11:45biology and molecular characteristics,
  • 11:48and then ranging to the
  • 11:49things that I typically would
  • 11:50study more like psychosocial behavior
  • 11:52on survivorship issues. And we
  • 11:54enrolled,
  • 11:55about thirteen hundred patients. At
  • 11:58one point, I remember having
  • 11:58a conversation with Eric and
  • 12:01saying, okay. You have so
  • 12:02much data. Maybe it's time
  • 12:03to stop enrolling. And I
  • 12:04said, you know what? I
  • 12:05think that's the right answer
  • 12:07and start really just delivering
  • 12:08on what we have.
  • 12:10And we had really high
  • 12:11response rates from patients. We've
  • 12:13collected surveys
  • 12:15over time. We have very
  • 12:16nice accrual to our biobank
  • 12:17too, which is, of course,
  • 12:18linked to the annotated data
  • 12:21data. And we've begun to
  • 12:23really,
  • 12:23capitalize on this resource. The
  • 12:26median follow-up is about eleven
  • 12:27years at this point. It's
  • 12:29probably about twelve now. And
  • 12:30so if anybody has any
  • 12:31good ideas, be please do
  • 12:33be in touch because the
  • 12:34goal is not to just
  • 12:35look at it with the
  • 12:35people that are working on
  • 12:36it right now, but to
  • 12:37really open it up so
  • 12:38people can ask questions or,
  • 12:40you know, put cohorts together
  • 12:42with with other people's datasets.
  • 12:44And so we've we've published
  • 12:46a lot on this, and
  • 12:47some of the work I'll
  • 12:48show you in the next
  • 12:49few minutes, focuses on,
  • 12:51analyses done. And one of
  • 12:53the issues
  • 12:54that,
  • 12:55I know is near and
  • 12:56dear to folks here in
  • 12:57the room that has come
  • 12:58up over and over and
  • 12:59over again is local therapy
  • 13:01decisions for our young patients.
  • 13:04Now the literature would tell
  • 13:05us that young patients have
  • 13:06a higher risk
  • 13:08of local recurrence,
  • 13:10but survival is the same.
  • 13:11And that's true especially when
  • 13:13you look at tumor subtypes.
  • 13:15And so
  • 13:17age should not be a
  • 13:18contraindication
  • 13:19to breast preservation. That's kind
  • 13:21of the mantra. There's data
  • 13:22to support that. I still
  • 13:23get phone calls from my
  • 13:25radiation oncologist. This person's only
  • 13:26twenty two. How much data
  • 13:28are there for a twenty
  • 13:29two year old? And
  • 13:32I say, you're right. But,
  • 13:32you know, we don't just
  • 13:32because we don't have data
  • 13:33doesn't mean that there's a
  • 13:35contraindication.
  • 13:35We gotta continue to grow
  • 13:37that. And so we we
  • 13:38try and treat our patients
  • 13:39this way, but we are
  • 13:40trying to learn from this.
  • 13:42And yet knowing
  • 13:44the issues around equal survivor
  • 13:46survival,
  • 13:48we still have seen this
  • 13:49trend, which is still I
  • 13:51think it's plateauing a little
  • 13:52bit now. We heard some
  • 13:54discussions about this earlier with
  • 13:55some of your
  • 13:57some of your surgical fellows
  • 13:58who are doing health services
  • 13:59research,
  • 14:00that, you know, young women
  • 14:02still go on not only
  • 14:03to choose mastectomy, but bilateral
  • 14:05mastectomy not infrequently
  • 14:07even when they don't have
  • 14:08a known hereditary predisposition to
  • 14:10breast cancer or any other
  • 14:12obvious,
  • 14:13family or personal,
  • 14:15history.
  • 14:16So, you know, what's going
  • 14:17on here? And is this
  • 14:18contributing
  • 14:19to better health in the
  • 14:21long run, or is this
  • 14:22contributing to more psychosocial issues,
  • 14:24or are they responding to
  • 14:26something and fixing a problem
  • 14:28with the wrong solution or
  • 14:30the right solution for them?
  • 14:31We don't know, but many
  • 14:32people are looking into this.
  • 14:33These are just data to
  • 14:34show that, you know, having
  • 14:36a contralateral prophylactic
  • 14:38mastectomy is not a panacea
  • 14:40to all that ails a
  • 14:41person, even though sometimes that's
  • 14:43the way I think some
  • 14:44women feel. It's in their
  • 14:45fight or flight reaction to
  • 14:46a new onset breast cancer.
  • 14:48And you can see here
  • 14:49the very high rates
  • 14:51of patients,
  • 14:53that have, you know, in
  • 14:54you know, self consciousness, feeling
  • 14:55less physically attractive,
  • 14:57dissatisfied with appearance, less feminine.
  • 14:59I mean, you and those
  • 15:00percentages are at fifty to
  • 15:02sixty percent less sexually attractive,
  • 15:04even avoiding people in a
  • 15:05substantial minority, body less whole,
  • 15:07dissatisfied, dissatisfied with scars. So,
  • 15:10you know, when there are
  • 15:11rigorous looks at how people
  • 15:13are feeling, there's a lot
  • 15:14of, you know, scars, both
  • 15:16physically and emotionally from extensive
  • 15:19surgery. And so trying to
  • 15:20understand
  • 15:21when we know there's no
  • 15:22clear survival advantage, what's what's
  • 15:23going on and making sure
  • 15:25people are making kind of
  • 15:26value based decisions that aren't
  • 15:28being driven by emotions of
  • 15:30the moment in fight or
  • 15:31flight, but are driven by,
  • 15:33kind of a calmness and
  • 15:35an ability to weigh the
  • 15:36pros and cons, I think,
  • 15:37is what many of us
  • 15:38are working on.
  • 15:39And one of the things
  • 15:40that one of my, postdocs
  • 15:42looked at recently was, well,
  • 15:43what are the data for
  • 15:44these young patients
  • 15:46when they don't have a
  • 15:47known hereditary predisposition to breast
  • 15:49cancer,
  • 15:51for a second primary? And
  • 15:53she looked in the young
  • 15:53woman's cohort.
  • 15:55And you can see here
  • 15:56we were able to identify
  • 15:58almost seven hundred patients who
  • 15:59hadn't had bilateral mastectomy,
  • 16:02and were, you know, still
  • 16:04in active follow-up.
  • 16:06Obviously, some of them had
  • 16:07competing
  • 16:08events like recurrence or metastases,
  • 16:11and some of them had,
  • 16:12nonbreast cancer,
  • 16:14nonbreast cancer deaths.
  • 16:17Sorry. Recurrence is probably not
  • 16:18the right word word there
  • 16:19because we're looking at oh,
  • 16:20recurrence,
  • 16:22elsewhere and recurrence. I think
  • 16:23it's local recurrence. And we
  • 16:24were looking at second non
  • 16:26breast primaries.
  • 16:28And you can see here
  • 16:29that
  • 16:31this group was representative
  • 16:34once you took the people
  • 16:34who had bilateral mastectomies away.
  • 16:37So there were relatively
  • 16:39small proportions
  • 16:40of mutation carriers. You can
  • 16:41see only about six percent
  • 16:43even though the rate of
  • 16:44mutation carriers in our cohort
  • 16:46is more like, you know,
  • 16:48for just BRCA one and
  • 16:49two, it's about fifteen percent.
  • 16:50And if you include kind
  • 16:52of those nine eight or
  • 16:53nine additional genes, it goes
  • 16:55up to about twenty five
  • 16:56percent,
  • 16:57because it is you know,
  • 16:58the prevalence is fairly high
  • 17:00if you look at our
  • 17:00very young patients.
  • 17:02And otherwise, there were no
  • 17:04other you know, it was
  • 17:04an interesting cohort,
  • 17:06but, I think the most
  • 17:07important thing is that still
  • 17:09within this group, fifty percent
  • 17:10said they had a family
  • 17:11history of breast or ovarian
  • 17:13cancer once you removed the
  • 17:14people who didn't have bilateral
  • 17:15mastectomies.
  • 17:17And here's what we saw.
  • 17:19The cumulative incidence of a
  • 17:20second primary breast cancer at
  • 17:23ten years
  • 17:24among almost seven hundred women
  • 17:26was pretty low. It was
  • 17:27like two point three percent
  • 17:29at ten years, one point
  • 17:31four percent.
  • 17:32So this is removing the
  • 17:33higher risk people, which most
  • 17:34of our population based data
  • 17:36don't have an understanding of
  • 17:38that ten percent who are
  • 17:39more likely to get breast
  • 17:40cancer or new primary over
  • 17:42the next ten to twenty
  • 17:43years.
  • 17:44We dug a little deeper
  • 17:45and looked at those who
  • 17:47did have a known hereditary
  • 17:48predisposition who'd kept their breast
  • 17:50at six percent. And you
  • 17:52can see here that it
  • 17:53was five and a half
  • 17:54times higher among those patients
  • 17:56who had germline
  • 17:57pathogenic variants. Not surprising. So
  • 18:00they had a nine point
  • 18:01one percent rate compared to
  • 18:03a one point seven percent
  • 18:05rate when you took them
  • 18:06away. So even lower at
  • 18:08ten years,
  • 18:10which is,
  • 18:11I think, very reassuring for
  • 18:13our young survivors.
  • 18:15Interestingly,
  • 18:16when we looked at other
  • 18:18differences, this was the only
  • 18:20other major factor that stood
  • 18:21out. Patients who had DCIS
  • 18:25had a higher risk of
  • 18:27a second primary
  • 18:29than patients who had presented
  • 18:31with an invasive breast cancer.
  • 18:32Now my immediately thinking was,
  • 18:34okay. The vast majority of
  • 18:35these people have trip have
  • 18:36hormone receptor positive breast cancer.
  • 18:38Our young patients don't wanna
  • 18:40take the hormones just like
  • 18:41our older patients don't for
  • 18:42DCIS. It's kinda optional for
  • 18:44DCIS.
  • 18:45Maybe that because there's no
  • 18:46clear survival advantage. So maybe
  • 18:48that's why we're seeing the
  • 18:50difference.
  • 18:50And we did look at
  • 18:51this in a subset analysis.
  • 18:53The numbers get super small.
  • 18:55There are only fifteen events,
  • 18:57but it wasn't a clear
  • 18:58explanation.
  • 18:59So more work to be
  • 19:00done. It may still be
  • 19:01the hormonal differences, but it
  • 19:03at least in our cohort,
  • 19:04it wasn't obvious
  • 19:06that it was just because
  • 19:07of a lack of use
  • 19:08of endocrine therapy in the
  • 19:09patients with DCIS compared to
  • 19:11the patients with invasive cancer.
  • 19:12So something to keep an
  • 19:13eye on
  • 19:14and just think about whether
  • 19:15or not if a young
  • 19:16person's diagnosed with DCIS,
  • 19:18then it may make more
  • 19:20sense to do something bilateral
  • 19:21because, you know, they don't
  • 19:23have a competing risk typically
  • 19:24of a systemic recurrence,
  • 19:26ironically, even though it feels
  • 19:28like a lot for a
  • 19:29noninvasive cancer. We could discuss
  • 19:31this later, Rachel. How do
  • 19:32you feel about this?
  • 19:34Alright. So so, you know,
  • 19:37when we think about doing
  • 19:38contralateral
  • 19:40mastectomy then, I think when
  • 19:41we support our young patients,
  • 19:43we all try and present
  • 19:44the pros and the cons
  • 19:45in a kind of a
  • 19:46nonjudgmental
  • 19:47way. And our now our
  • 19:48surgeons focus on this a
  • 19:49lot. The other huge component
  • 19:52to this when you think
  • 19:53about pros and cons is,
  • 19:55will they get peace of
  • 19:56mind with this? And I
  • 19:58know you have work going
  • 19:59on here looking into this,
  • 20:01and I'm thrilled that I'm
  • 20:02part of,
  • 20:04Rachel Greenup and Shoshana Rosenberg's,
  • 20:07work called Consider,
  • 20:09which you guys have open
  • 20:10here too,
  • 20:11which is a pragmatic
  • 20:13implementation. It's a hybrid design
  • 20:15effectiveness and implementation
  • 20:17study
  • 20:18where we are putting
  • 20:20a, decision support tool into
  • 20:23effect,
  • 20:24over time at,
  • 20:27four sites in North America.
  • 20:29Where are the sites, Rachel?
  • 20:29It's us, it's you, Duke,
  • 20:32and Cornell.
  • 20:33Right? And so over time,
  • 20:35hopefully, we will be able
  • 20:36to help our young patients
  • 20:38in particular. And this is
  • 20:39built out of Rachel and
  • 20:41and,
  • 20:42Shoshana's k award work to
  • 20:44try and support patients better
  • 20:46in the moment to make
  • 20:48good decisions for themselves
  • 20:49around the issue of how
  • 20:51much breast surgery do I
  • 20:52need,
  • 20:53and does it make sense
  • 20:54to take off the other
  • 20:55side and and do preventative
  • 20:57work.
  • 20:58So very exciting and and
  • 20:59nice to see this kind
  • 21:00of coming from the data
  • 21:02from the patients all the
  • 21:03way through to an intervention
  • 21:05that's actually in our clinics
  • 21:07pretty soon. Pretty soon.
  • 21:09So very exciting.
  • 21:11Now getting back to that
  • 21:12graph that I showed you
  • 21:13where our youngest patients who
  • 21:14were in red were doing
  • 21:16as poorly as our oldest
  • 21:17patients who have different reasons
  • 21:19for their disparities,
  • 21:20now we're separating the that
  • 21:22graph by the,
  • 21:24canonical
  • 21:26breast cancer subtypes. So we've
  • 21:27got hormone receptor positive,
  • 21:30lower grade, which is a
  • 21:31surrogate for luminal a subtype
  • 21:33up on the left,
  • 21:35HER2 positive on the bottom
  • 21:37left, and then you've got
  • 21:38the high grade hormone receptor
  • 21:40positive, HER2 positive, or HER2
  • 21:43negative,
  • 21:44and then on the bottom
  • 21:45right, triple negative. And you
  • 21:46can see
  • 21:47that where's the biggest
  • 21:51deficit? Where's the biggest,
  • 21:53disparity? It's actually
  • 21:55in the group of patients
  • 21:57that we think of as
  • 21:59kind of the easiest to
  • 22:01treat with early stage breast
  • 22:02cancer, those with the the
  • 22:04lower risk
  • 22:05in theory, low grade or
  • 22:07intermediate grade,
  • 22:09hormone receptor positive disease.
  • 22:11And that kinda makes sense.
  • 22:13Right? Whenever you have a
  • 22:14treatment
  • 22:16that is effective,
  • 22:18you see disparities in any
  • 22:20population.
  • 22:22Right? Because you can't it's
  • 22:24harder to see
  • 22:25disparities in a population when
  • 22:27you don't have effective treatment.
  • 22:28Disparities typically come out, especially
  • 22:30when they're related to access
  • 22:32or uptake of therapies,
  • 22:35often in where you have
  • 22:36effective therapy.
  • 22:38And yet we also think
  • 22:39there may be some biologic
  • 22:40differences in our youngest patients
  • 22:42who get these kind of
  • 22:44wimpier
  • 22:45looking
  • 22:45tumors.
  • 22:47So what are the data
  • 22:49for that? So our group
  • 22:50and others, and I'm showing
  • 22:51you the data from the
  • 22:52text in the SOFT trial
  • 22:53that were published
  • 22:55a year or so ago,
  • 22:56that younger women are developed
  • 22:59more luminal b than luminal
  • 23:01a tumors you can see
  • 23:02here. So, you know, in
  • 23:04the in the bright blue
  • 23:05or the turquoise is the
  • 23:07luminal b's and the youngest
  • 23:09proportionally greater. And then you
  • 23:10see the kind of flip
  • 23:11of that when you get
  • 23:12to over forty, still young,
  • 23:14but not under forty.
  • 23:16And then when the group
  • 23:17delved into more of the
  • 23:18genomics, they saw more
  • 23:20HRD,
  • 23:21more copy number alteration
  • 23:23in the younger patients. And
  • 23:25our groups looked at this
  • 23:26and also seen some differences
  • 23:27in more specific genomic changes
  • 23:30as well.
  • 23:31And then when we looked
  • 23:32at the luminal a and
  • 23:33luminal b in text and
  • 23:35soft,
  • 23:36they're even among those two
  • 23:38different subsets,
  • 23:39the youngest patients seem to
  • 23:41do worse
  • 23:43in terms of their disease
  • 23:44free survival.
  • 23:46So some of this may
  • 23:48be about
  • 23:49size of tumors still and
  • 23:51uptake of care, but there
  • 23:52may also be something going
  • 23:53on biologically. And we we
  • 23:55just don't know all the
  • 23:56answers. But
  • 23:57but one would think then
  • 23:59when you see these lower
  • 24:00risk cancers
  • 24:01and then you see that
  • 24:02a younger person
  • 24:03has a higher risk, well,
  • 24:05maybe we should just give
  • 24:06them all the tools we
  • 24:07have. Right? Because they're at
  • 24:09risk, and we don't wanna
  • 24:10leave any kind of risk
  • 24:11reduction on the table.
  • 24:13And, unfortunately,
  • 24:15our current data
  • 24:17do lean towards that. These
  • 24:19are the data from kind
  • 24:21of the the hallmark genomic
  • 24:23testing studies that have been
  • 24:24done over the last decade,
  • 24:26the TAILORx trial, the MIND
  • 24:28ACT study and responder,
  • 24:31you know, whether or not
  • 24:32person had node positive or
  • 24:34node negative breast cancer,
  • 24:36chemotherapy.
  • 24:37And these were studies with
  • 24:39genomic testing and people in
  • 24:41a lower moderate risk group
  • 24:43randomized to chemo or no
  • 24:45chemo, just for simplicity.
  • 24:47And this these studies have
  • 24:49spared many, many postmenopausal
  • 24:51women
  • 24:51from getting
  • 24:53chemotherapy because
  • 24:54all of them showed that
  • 24:55among postmenopausal
  • 24:57women with ER positive breast
  • 24:58cancer
  • 24:59where they had low to
  • 25:01intermediate oncotype
  • 25:02or,
  • 25:03mammoprint scores,
  • 25:04whether it was node negative
  • 25:06or node positive when you
  • 25:07think of responder,
  • 25:08that chemotherapy
  • 25:10did not add value.
  • 25:12But, unfortunately, in premenopausal
  • 25:14women,
  • 25:15somehow, there is clear value.
  • 25:18And you can see this,
  • 25:19you know, estimates in the
  • 25:21range of about six percent.
  • 25:23It's pretty amazing that it's
  • 25:24six percent in TAILORx, it's
  • 25:26five percent in Mindac, it's
  • 25:27five percent in,
  • 25:29responder.
  • 25:30And so that might lead
  • 25:33in an unnuanced
  • 25:34way for everybody to look
  • 25:35and go, oh, no. We
  • 25:36should we should be giving
  • 25:37all these young women who
  • 25:38are higher risk chemotherapy.
  • 25:40But the obvious question for
  • 25:42anybody who treats these patients
  • 25:43is
  • 25:44that what's really different about
  • 25:46going from a premenopausal
  • 25:48woman to a postmenopausal
  • 25:50woman is the fact that
  • 25:52premenopausal women still have ovarian
  • 25:54function. And we've known for
  • 25:56many, many, many, many years
  • 25:58that ovarian function and turning
  • 26:00off ovaries
  • 26:01has a profound
  • 26:03impact on breast cancer outcomes
  • 26:05and control
  • 26:06in the setting of now,
  • 26:07we know, ER positive breast
  • 26:09cancer. And so the the
  • 26:11major question that confounds all
  • 26:13of those studies is how
  • 26:14much of that chemotherapy
  • 26:15benefit
  • 26:16in our premenopausal
  • 26:18patients
  • 26:19is due to the chemoendocrine
  • 26:20effect of the chemotherapy.
  • 26:23This is still a major
  • 26:24outstanding question, and one of
  • 26:26the clues that suggest that
  • 26:27it may be
  • 26:28all of it, if not
  • 26:30a large part of it,
  • 26:31it comes up to us
  • 26:32from the TAILORx trial.
  • 26:34Whereas you can see, if
  • 26:36you look on the right
  • 26:37in the blue areas,
  • 26:38you know, there was a
  • 26:39lot of work that's been
  • 26:40done around clinical risk. And,
  • 26:42of course, the higher clinical
  • 26:43risk a person has,
  • 26:45the higher the risk reduction
  • 26:47a person might get
  • 26:49from any given treatment. Right?
  • 26:50The absolute benefits would be
  • 26:52great. So if you take
  • 26:53the recurrence score on the
  • 26:54bottom and you say a
  • 26:55recurrence score of twenty one
  • 26:56to twenty five and they
  • 26:57have a high
  • 26:59clinical risk, the estimate is
  • 27:00almost twelve percent absolute benefit
  • 27:03from chemotherapy in someone like
  • 27:05that under age fifty who
  • 27:07falls in that group. So
  • 27:08that feels like it's a
  • 27:09no brainer to give them
  • 27:10chemotherapy.
  • 27:11And we know that our
  • 27:12younger patients are not being
  • 27:13screened.
  • 27:14They're less likely to present
  • 27:16with a smaller tumor. Right?
  • 27:17Like we talked about, they
  • 27:19have higher risks from the
  • 27:20beginning. But wouldn't you know
  • 27:21it? When we looked at
  • 27:22the youngest patients in TAILORx,
  • 27:25the forty and under,
  • 27:27see where that hazard ratio
  • 27:29is?
  • 27:30No clear benefit. They're below
  • 27:33one. So and it's not
  • 27:34the tiniest of numbers. There's
  • 27:36two hundred patients in that
  • 27:37group. So what possibly could
  • 27:39be going on there? And
  • 27:40it's almost a dose response
  • 27:42curve that you see. The
  • 27:43older the woman is under
  • 27:45the age of fifty,
  • 27:47the more likely she is
  • 27:48to get benefit from from
  • 27:50chemotherapy, which flies in the
  • 27:51face
  • 27:52of all of the things
  • 27:53we know about the benefits
  • 27:55of chemotherapy.
  • 27:56And and the point is
  • 27:57that a lot of that
  • 27:58probably is that the youngest
  • 28:00patients are the least likely
  • 28:02to get ovarian function
  • 28:05suppression
  • 28:06from chemotherapy
  • 28:07personal
  • 28:09permanently
  • 28:10from the conventional chemotherapies that
  • 28:13we use. So this really
  • 28:14does remain a really important
  • 28:16question.
  • 28:17And in the meantime, when
  • 28:18those studies were coming to
  • 28:19fruition
  • 28:20accrual,
  • 28:21we also have the soft
  • 28:23in text data, but particularly
  • 28:24soft
  • 28:25down the left that showed
  • 28:27a very, very large six
  • 28:30percent or five percent absolute
  • 28:31benefit in disease free survival
  • 28:34from just adding ovarian suppression
  • 28:35to tamoxifen.
  • 28:37And then if you give
  • 28:38to in premenopausal
  • 28:39women,
  • 28:40and then if you give
  • 28:42an aromatase inhibitor with that
  • 28:43ovarian suppression, you see an
  • 28:45even bigger bump. So at
  • 28:47the same time that these
  • 28:47studies were coming out, we
  • 28:49were also seeing
  • 28:51TexanSoft
  • 28:52showing us that those old
  • 28:53studies were not giving the
  • 28:55best endocrine therapy backbone that
  • 28:57they could possibly have. And,
  • 28:58potentially,
  • 28:59could these benefits somewhere between
  • 29:01five to ten percent in
  • 29:02higher risk young women,
  • 29:04could they
  • 29:05offset and be the reason
  • 29:07that the chemotherapy is showing
  • 29:09such a difference
  • 29:10by that age or pre
  • 29:12and postmenopausal
  • 29:13status? Well,
  • 29:15many of us have to
  • 29:15practice in this, so we
  • 29:16make decisions every day weighing
  • 29:18the pros and cons and
  • 29:19sharing those data with patients.
  • 29:21Fortunately, there are two studies
  • 29:23that are looking at this.
  • 29:24This is the one in
  • 29:25North America, the OFFSET trial.
  • 29:26I don't know if you
  • 29:27guys have it open here
  • 29:28yet, but it's looking at
  • 29:30randomizing women
  • 29:32to chemo or no chemo
  • 29:33who fall within the groups
  • 29:35of that intermediate or low
  • 29:37risk groups. And everybody gets
  • 29:39to start with the best
  • 29:41chemo I mean, the best
  • 29:42hormonal therapy backbone in terms
  • 29:44of risk reduction.
  • 29:45You can see it here.
  • 29:46It's an aromatase inhibitor plus,
  • 29:48ovarian suppression.
  • 29:49And there's a corresponding study
  • 29:51in the UK,
  • 29:53that one of our colleagues
  • 29:54who we trained who I
  • 29:55we trained with Inej Vazluiz
  • 29:57is running now,
  • 29:58across Europe that will be,
  • 30:01testing the same thing in
  • 30:02a cohort of patients in,
  • 30:05in the UK. So we
  • 30:06will have this answer at
  • 30:08some point assuming these studies
  • 30:10accrue. But in the meantime,
  • 30:11we do make decisions.
  • 30:13And, you know, I think
  • 30:14it's really important to know
  • 30:15that ovarian suppression is is
  • 30:17a really important therapy for
  • 30:18our patients,
  • 30:19and it does add to
  • 30:21tamoxifen or an aromatase inhibitor.
  • 30:23It is a powerful
  • 30:25risk reducer. By itself,
  • 30:27adds
  • 30:27thirty percent over tamoxifen alone
  • 30:29and adds even more when
  • 30:30it's given with an aromatase
  • 30:32inhibitor.
  • 30:33Not so clear that it
  • 30:34adds as much in people
  • 30:35who got chemotherapy,
  • 30:37but isn't ovarian suppression a
  • 30:39nicer way than chemotherapy to
  • 30:41have that that functional effect
  • 30:43for some, maybe for some,
  • 30:44maybe not so much if
  • 30:45someone's not gonna be adherent.
  • 30:47And there are cost to
  • 30:48ovarian suppression treatment.
  • 30:50The side effects,
  • 30:52the time and financial toxicity
  • 30:54of coming into a cancer
  • 30:55center every, you know, one
  • 30:56to three months, maybe every
  • 30:58six months. I end as
  • 31:00we can test the six
  • 31:01month regimens in our young
  • 31:02people. So and this can
  • 31:03really impact on how a
  • 31:04person,
  • 31:06how a person tolerates therapy.
  • 31:08Adherence is a huge issue.
  • 31:10That's something that we also
  • 31:11studied
  • 31:12before our young women's cohort
  • 31:14was off the ground. And
  • 31:15these are old data
  • 31:17from some Medicare and Medicaid
  • 31:19datasets that I had the
  • 31:20pleasure of working in. And
  • 31:22way back when we showed
  • 31:23that adherence wanes over time
  • 31:24to Tamoxifen alone and that
  • 31:26young age and black race
  • 31:28were predictors of non adherence.
  • 31:30We talked about how did
  • 31:31disparities
  • 31:32come up. They come up
  • 31:32when you have effective therapies
  • 31:34that people don't either use
  • 31:35or access themselves to. And
  • 31:36then Dawn Hirschman has taken
  • 31:38this work and done a
  • 31:39lot more with it, showing
  • 31:40that both adherence matters
  • 31:42as well as the fact
  • 31:43that,
  • 31:43again, young age, those less
  • 31:45than forty patients were more
  • 31:46likely to discontinue their hormonal
  • 31:48therapy, and they were more
  • 31:50likely to just non adhere,
  • 31:52not take it as directed,
  • 31:54even if they weren't completely
  • 31:55stopping it. So this may
  • 31:57be one of the bigger
  • 31:58contributors
  • 31:59to why young patients
  • 32:01don't do as well,
  • 32:04beyond some of the biology
  • 32:05as I showed you in
  • 32:06the presenting with larger larger
  • 32:09tumors and
  • 32:10things. Interestingly, and these are
  • 32:11hot off the presses data
  • 32:13from this year's ESMO,
  • 32:16there was a group across
  • 32:17France that has modeled out
  • 32:19using
  • 32:20French national health system data
  • 32:23the potential
  • 32:24impact
  • 32:25of if all young women
  • 32:27were adherent. And they showed
  • 32:29in their data set that,
  • 32:30of course, like we've seen
  • 32:31in America and other data
  • 32:32sets, younger patients have lower
  • 32:35persistence with endocrine therapy. And,
  • 32:37again, it's very clear that
  • 32:38it goes down,
  • 32:40down with age,
  • 32:42and it's very, you know,
  • 32:43again, a dose response curve
  • 32:44almost.
  • 32:45And our young patients in
  • 32:47France as well have, worse
  • 32:49disease free survival. Again, some
  • 32:50of it may be biology,
  • 32:51but clearly, there's a link.
  • 32:53We know adherence matters.
  • 32:55And then they modeled out,
  • 32:56which I thought I've thought
  • 32:58about this for years, but
  • 32:58I'd never seen anybody do
  • 33:00it.
  • 33:02What would happen if those
  • 33:04women under thirty five where
  • 33:05we see the worst outcomes,
  • 33:08what would happen if we
  • 33:09model out scenarios
  • 33:11that just prevented them from
  • 33:12discontinuing their endocrine therapy? In
  • 33:14the fantasy world that you
  • 33:15could kind of tie them
  • 33:16down and do, like, direct
  • 33:17observe therapy. Like, nobody's gonna
  • 33:18do that. But but they
  • 33:20modeled it out. And as
  • 33:21you can see here,
  • 33:22if
  • 33:23French women took their hormonal
  • 33:25therapy,
  • 33:26they would have almost a
  • 33:28six percent improvement
  • 33:30in
  • 33:31survival
  • 33:32at five years. So pretty
  • 33:34compelling data to continue to
  • 33:36think about how do we
  • 33:37optimize adherence, how do we
  • 33:39help people to understand
  • 33:40the importance of these drugs,
  • 33:42how do we help them
  • 33:43tolerate
  • 33:44these drugs because these are
  • 33:45some of the best tools
  • 33:46we have
  • 33:47against ER positive breast cancer
  • 33:50for sure.
  • 33:51And one of the areas
  • 33:52where I focused on and,
  • 33:54again, some of this was
  • 33:55about, you know, when I
  • 33:56was the the we taught
  • 33:57working in Eric's clinic, I
  • 33:59was a we wanting to
  • 34:00be a mom myself, and
  • 34:03a lot of women were
  • 34:03coming in and saying, you
  • 34:05know,
  • 34:06wait. You're gonna give me
  • 34:07hormonal therapy, and I have
  • 34:09to take it. At that
  • 34:09time, it was only five
  • 34:10years. We didn't have the
  • 34:11ten year data yet. I
  • 34:13have to take it for
  • 34:13five years, and this was
  • 34:14you know, this this bump
  • 34:15was diagnosed in the obese
  • 34:18office. I my friends are
  • 34:19all having their babies now.
  • 34:20What are you telling me?
  • 34:22And, you know, one of
  • 34:23the things that we documented
  • 34:25both with the young survival
  • 34:26coalition years ago and then
  • 34:28through our young women's cohort
  • 34:29over time, and this is
  • 34:30data from Katie Ruddy and
  • 34:31Phil Porvoo in our in
  • 34:33our group
  • 34:34originally was that, you know,
  • 34:35fertility was just a huge
  • 34:37issue for these young women
  • 34:38that wasn't getting a lot
  • 34:39of attention way back when.
  • 34:41Fortunately, over the last two
  • 34:43decades, we've all been paying
  • 34:44more attention to it. But
  • 34:45you can see here, it's
  • 34:46an issue both at diagnosis
  • 34:48and then issue. And this
  • 34:49is all forty and under.
  • 34:51And and it's an issue
  • 34:51that kind of still is
  • 34:53there in longer term survivorship.
  • 34:54And even if women
  • 34:56are not going to go
  • 34:57on and have a biologic
  • 34:59child, helping them
  • 35:01to acknowledge that loss and
  • 35:03grieve it, bringing you know,
  • 35:04we bring in the social
  • 35:05workers at the beginning,
  • 35:06but but there's also probably
  • 35:08a need for attention to
  • 35:09this in the long term
  • 35:11follow-up, recognizing it's hard to
  • 35:12do that in our resource
  • 35:13constrained trained environment. But it
  • 35:15can be a reason for
  • 35:16some, and for many women
  • 35:18that I've been told who
  • 35:19are, you know, who are
  • 35:20in this, it's even more
  • 35:21impactful on their day to
  • 35:23day emotional health than the
  • 35:25cancer itself and the fear
  • 35:27of recurrence, although that is
  • 35:28impactful for many
  • 35:30in this young cohort. So
  • 35:31a really important area. When
  • 35:33we dug deeper in the
  • 35:35young women's cohort
  • 35:36about kind of what was
  • 35:37going on here and, you
  • 35:38know, was it really something
  • 35:40that might be impacting on
  • 35:41their adherence as others had
  • 35:42shown? We found that
  • 35:44about a hundred and sixty
  • 35:46women, so twenty six percent
  • 35:47of those who had reported
  • 35:49that they were cared about
  • 35:50fertility,
  • 35:51said that it affected their
  • 35:53treatment decisions. Right. So it
  • 35:54was impacting on the things
  • 35:56that reduce risk. This is
  • 35:58where
  • 35:58survivorship
  • 36:00meets survival.
  • 36:01So if anybody thinks that
  • 36:03survivorship is just make people
  • 36:04feel good, which is a
  • 36:05good thing and an end
  • 36:06in and of itself,
  • 36:07I think the other critical
  • 36:08thing is if we don't
  • 36:09take good care of our
  • 36:10survivors and help to meet
  • 36:11them with for their needs,
  • 36:14they're gonna speak with their
  • 36:15feet around things that actually
  • 36:16impact their survival. So these
  • 36:18two things need to be
  • 36:19super hand in hand when
  • 36:21we plan our cancer centers
  • 36:22and when we think about
  • 36:23interventions.
  • 36:25And what we showed when
  • 36:26we dug deeper is that,
  • 36:28sure, most people were kind
  • 36:29of taking their therapies,
  • 36:31but ninety people told us
  • 36:33that, you know, four of
  • 36:34them, one percent chose not
  • 36:35to get chemo. Maybe it
  • 36:36was a real choice and
  • 36:37the benefits would have been
  • 36:38small.
  • 36:39Two percent chose one regimen
  • 36:41over the other. Interesting.
  • 36:43One percent considered not receiving
  • 36:44endocrine therapy, considered it. Three
  • 36:47percent actually chose not to
  • 36:48receive endocrine therapy, and eleven
  • 36:50percent said they wanted to
  • 36:52take less than the five
  • 36:53years.
  • 36:55And you can see how
  • 36:56and this is a group
  • 36:57that's
  • 36:58telling us
  • 36:59this. They're participating in a
  • 37:00longitudinal
  • 37:01cohort study.
  • 37:03These are the, like, the
  • 37:03the people who are kind
  • 37:04of doing what the doctor
  • 37:05tells them to do. Now
  • 37:06imagine what's happening in the
  • 37:08real world
  • 37:09around endocrine therapy adherence. That's
  • 37:11why you see huge rates
  • 37:12of nonadherence
  • 37:13with, you know, hypertension. Well,
  • 37:14they're not that much better
  • 37:15with their anticancer therapies when
  • 37:17they're given chronically.
  • 37:18So
  • 37:19this in part led to
  • 37:21the
  • 37:22positive trial.
  • 37:23And the positive trial was
  • 37:26a kind of
  • 37:27multinational
  • 37:28effort to try to help
  • 37:30women who were facing that
  • 37:32clinical conundrum of,
  • 37:34I want my baby
  • 37:35yesterday, and now I have
  • 37:36to deal with this jail
  • 37:38sentence of endocrine therapy. And
  • 37:40I want to get good
  • 37:41breast cancer care, but I
  • 37:42don't wanna put my whole
  • 37:43life on hold. I know
  • 37:45I'm likely be a survivor.
  • 37:46And, you know, I really
  • 37:47don't feel like rolling the
  • 37:48roulette,
  • 37:49you know, at the roulette
  • 37:50table and feeling like I'm
  • 37:52taking chances in any way.
  • 37:53Not that having a baby
  • 37:54is a spectator sport. So
  • 37:56the the goal was to
  • 37:57say,
  • 37:58how can we help women
  • 38:00to have best breast cancer
  • 38:02care and at the same
  • 38:03time
  • 38:04not put their lives on
  • 38:05hold? And so the study
  • 38:06was designed
  • 38:07to say, let's take a
  • 38:08break from endocrine therapy.
  • 38:10We know
  • 38:11that the hazards of recurrence
  • 38:13in women with ER positive
  • 38:15breast cancer lasts for thirty
  • 38:16years.
  • 38:18We would typically stop you
  • 38:19at five years of endocrine
  • 38:20therapy or ten. What if
  • 38:22we took a break and
  • 38:23you still got five or
  • 38:24ten years? Is that, you
  • 38:25know, a year or two
  • 38:27or three into it gonna
  • 38:29make a much bigger difference
  • 38:30than taking that break between
  • 38:32years five and seven, which
  • 38:33is what we were doing
  • 38:34and, again, you know, conventionally?
  • 38:37And we had a whole
  • 38:38slew of data,
  • 38:39retrospective, I'll be, that said
  • 38:41women who went on to
  • 38:42have a pregnancy after breast
  • 38:43cancer
  • 38:44seemed to do just as
  • 38:45well as women who didn't
  • 38:47go on to have a
  • 38:48pregnancy, whether it was ER
  • 38:50positive
  • 38:51or ER negative, despite concerns
  • 38:53that, you know, getting pregnant
  • 38:55might throw gasoline
  • 38:57on the embers of a
  • 38:58recurrence.
  • 38:59There was no data in
  • 39:00the modern era that actually
  • 39:03made that look like it
  • 39:04was a reality, but still
  • 39:05people were worried about. So
  • 39:07this was also gonna look
  • 39:08at that. But it was
  • 39:09really testing the question of
  • 39:10is an interruption
  • 39:13a safe enough thing to
  • 39:14do. Now as you can
  • 39:16imagine, we couldn't do a
  • 39:17randomized trial of this because,
  • 39:19I don't know about you,
  • 39:20but what person and their
  • 39:21loved ones would go on
  • 39:22the you get a baby
  • 39:23and you don't get a
  • 39:24baby study?
  • 39:26Maybe someone, but we weren't
  • 39:27that draconian. So what we
  • 39:29did was a single arm
  • 39:30trial modeling
  • 39:32after you would go on
  • 39:33that? Is that what you're
  • 39:34saying?
  • 39:35A single arm trial modeling
  • 39:37after other work that had
  • 39:39been going on recently where
  • 39:40we set a threshold for
  • 39:42safety.
  • 39:43And you can see the
  • 39:44schema at the bottom. We
  • 39:45said, okay. What are people
  • 39:46comfortable with? We made this
  • 39:48decision. Again, multinational
  • 39:50with, patient advocates at the
  • 39:52table. There was a lot
  • 39:53of back and forth on
  • 39:54how long we were gonna
  • 39:55make them take endocrine therapy.
  • 39:57You know, obviously, we're not,
  • 39:58again, not tying people down.
  • 39:59Everybody thought it was safe
  • 40:00enough to get at least
  • 40:01eighteen months. And then we
  • 40:03stopped the study at having
  • 40:05taken at least thirty months.
  • 40:06And the reason for that
  • 40:07was to make it a
  • 40:08real experiment
  • 40:09because most people practically would
  • 40:11say, oh, get at least
  • 40:12three years because that's close
  • 40:14to five years, and we
  • 40:15know that five years is
  • 40:16better than two years is
  • 40:17better than one year. So
  • 40:18it's very practical, but allowing
  • 40:20women to do it a
  • 40:21little earlier and then flexible.
  • 40:23Look at the patients tolerate.
  • 40:25Then they had needed to
  • 40:26have a three month washout
  • 40:28to get the endocrine therapy
  • 40:29out of their system. They
  • 40:30were supported to have a
  • 40:32two year up to a
  • 40:33two year break to get
  • 40:34pregnant, however they could get
  • 40:36pregnant,
  • 40:37and then nurse if they
  • 40:38wanted to and could, and
  • 40:40then ideally get back on
  • 40:41with a you know, that
  • 40:42well, up to a two
  • 40:43year window, and then we're
  • 40:44following them for long term
  • 40:46following. They would complete
  • 40:47a five to ten year
  • 40:48protocol depending on tolerance and
  • 40:50what they decided about their
  • 40:51basic risk.
  • 40:53So who did we enroll?
  • 40:54We enrolled
  • 40:55this is our, you know,
  • 40:56our popular our ITT population,
  • 40:58five hundred and sixteen people.
  • 41:01As you can see, they
  • 41:02represent, you know, those who
  • 41:03get young onset breast cancer.
  • 41:05The majority,
  • 41:06or the biggest group was
  • 41:07between thirty five and thirty
  • 41:09nine. When you look at
  • 41:09our young women's cohort, the
  • 41:11average age is thirty seven.
  • 41:12So I think it's pretty
  • 41:13spot on. That was forty
  • 41:13and under.
  • 41:15Most of the women who
  • 41:16were doing this had not
  • 41:17had a prior pregnancy, no
  • 41:18surprise, those would be the
  • 41:19ones that would be driven
  • 41:21to do this interruption and
  • 41:22be on the trial. And
  • 41:23you can see that it
  • 41:24was mostly patients with stage
  • 41:26one and stage two disease.
  • 41:28About six percent had stage
  • 41:29three disease. I can tell
  • 41:31you about forty percent had
  • 41:32node positive disease. So it
  • 41:33wasn't completely wimpy cancers.
  • 41:36It was, you know, there
  • 41:37were it was kind of
  • 41:38what you tend to see,
  • 41:40but the highest risk were
  • 41:41not that well represented.
  • 41:43Alright. Here's, I think, the
  • 41:45most important outcome.
  • 41:47I was that most women
  • 41:48got pregnant.
  • 41:49Most women. So seventy four
  • 41:51percent of women had at
  • 41:52least one person one pregnancy
  • 41:54on the trial,
  • 41:55and sixty four percent of
  • 41:57the total or eighty six
  • 41:59percent of those who got
  • 42:00pregnant had at least one
  • 42:02live birth. So that was
  • 42:03that was pretty cool. That
  • 42:04was really good news.
  • 42:06There were some miscarriages. There
  • 42:07were some abortions. I still
  • 42:08have some patients
  • 42:09that, you know, were on
  • 42:10the trial and never got
  • 42:11pregnant. Really heartbreaking and hard
  • 42:13for them, and always challenging
  • 42:14to get them back on
  • 42:15the hormones.
  • 42:17And then obviously the most
  • 42:18important outcome that to the
  • 42:20to us worrying about our
  • 42:22patients recurring
  • 42:23was the breast cancer free
  • 42:24interval did not
  • 42:26get as high as the
  • 42:28prespecified
  • 42:29safety threshold.
  • 42:30There were forty four events
  • 42:32in positive,
  • 42:33and the threshold was set
  • 42:35at forty six
  • 42:36based on text and soft
  • 42:38data.
  • 42:40Now we had also
  • 42:41conducted a calculated control cohort
  • 42:44when we had about half
  • 42:45of,
  • 42:46positive accrued
  • 42:48that controlled for BMI,
  • 42:50nodal status, treatments received, including
  • 42:53chemo, including AI or not.
  • 42:55And that's the curve on
  • 42:56the right for BCIFI,
  • 42:58which is comparing the positive
  • 43:00cohort
  • 43:01to that TextSoft
  • 43:03control analysis cohort, and there
  • 43:05was no difference. If anything,
  • 43:07the positive folks looked a
  • 43:08little bit better.
  • 43:10And this is a forty
  • 43:11one month follow-up, which is
  • 43:13about
  • 43:14people were about two years
  • 43:15on average after their diagnosis
  • 43:18when they were enrolled. So
  • 43:19this is about five year
  • 43:20follow-up from their breast cancer
  • 43:21diagnosis. So it's early days
  • 43:23to see whether or not
  • 43:24there's actual impact, but this
  • 43:26was the primary outcome of
  • 43:27the trial.
  • 43:28What I think is the
  • 43:29most important
  • 43:30analysis in positive, which was
  • 43:32buried in the supplement of
  • 43:34the of the article,
  • 43:35is this landmark analysis.
  • 43:37And this was the people
  • 43:39on positive.
  • 43:40The top line is the
  • 43:41people who didn't get pregnant
  • 43:43by eighteen months and hadn't
  • 43:45had a recurrence and then
  • 43:46following them out. So the
  • 43:47exposure is pregnant or not
  • 43:49by eighteen months.
  • 43:50Top line is not pregnant.
  • 43:53Bottom line is the majority
  • 43:54who got pregnant and not
  • 43:56a snidge
  • 43:58of signal
  • 43:59that the pregnancy
  • 44:00itself
  • 44:01would impact on the risk
  • 44:03of recurrence.
  • 44:04So that, I think, is
  • 44:06very, very reassuring
  • 44:07and can kind of really
  • 44:09corroborate
  • 44:10all of the old data
  • 44:11that we have that suggests
  • 44:12that a pregnancy itself
  • 44:14does not worsen a risk
  • 44:16of recurrence
  • 44:17in a breast cancer survivor.
  • 44:19And we did this in
  • 44:20a Cox model too and
  • 44:21did not see if anything,
  • 44:22the people who got pregnant
  • 44:23looked a lot better, although
  • 44:24I don't tell my patients
  • 44:26to go out and get
  • 44:26pregnant for treatment of their
  • 44:27breast cancer for lots of
  • 44:29good reasons.
  • 44:30We've recently looked at some
  • 44:31other secondary outcomes like time
  • 44:34to pregnancy and no surprise.
  • 44:36What was the biggest factor
  • 44:37that predicted pregnancy?
  • 44:39Age. The younger one was,
  • 44:41the more likely she was
  • 44:42to become pregnant, as you
  • 44:43can see here.
  • 44:45Interestingly,
  • 44:46we looked at the chance
  • 44:47of any pregnancy
  • 44:49and age, of course, rang
  • 44:50in there too. But the
  • 44:51other big one that rang
  • 44:53in there was the use
  • 44:54of reproductive
  • 44:56technology, the preservation
  • 44:58of eggs or embryos
  • 45:00or both
  • 45:01before treatment. That was the
  • 45:03other big predictor
  • 45:05of pregnancy, and, obviously, that's
  • 45:06independent of age. So what
  • 45:08does that tell us? That
  • 45:10tells us that we need
  • 45:10to make sure that we
  • 45:11have these services available for
  • 45:13our patients, especially if they're
  • 45:14older. We just looked at
  • 45:16this in the young women's
  • 45:17cohort. And you can see
  • 45:18here, again, at the median
  • 45:19follow-up of eleven years, and
  • 45:20this includes ER positive patients
  • 45:21and ER negative patients,
  • 45:24we have similar numbers, which
  • 45:25is incredible.
  • 45:26Seventy three percent reported a
  • 45:28pregnancy.
  • 45:29Sixty five percent reported at
  • 45:31least one live birth. It's
  • 45:32really similar to positive, which
  • 45:34is weird because it's not
  • 45:35an overlapping group.
  • 45:36The median time from diagnosis
  • 45:38to first pregnancy in this
  • 45:39cohort was forty eight months.
  • 45:40Of course, we're gonna look
  • 45:41at their longer term outcomes
  • 45:42and their disease outcomes. But
  • 45:44what we've modeled first is
  • 45:46variables associated with pregnancy and
  • 45:48variables associated with live birth.
  • 45:49And in our cohort, it
  • 45:50was financial comfort along with
  • 45:52age and then fertility preservation
  • 45:55along with age. So, again,
  • 45:56the big signal here is
  • 45:58we need to keep lobbying
  • 46:00for insurers to pay for
  • 46:01this and work within our
  • 46:02systems to make sure that
  • 46:03people are able to be
  • 46:04referred in a timely fashion
  • 46:06to get this important service
  • 46:08if it matters to them.
  • 46:10So now I'm gonna switch
  • 46:11gears and just discuss for
  • 46:13a few minutes what we've
  • 46:14been doing now for almost
  • 46:16two decades
  • 46:17to try
  • 46:18and
  • 46:19get this information.
  • 46:21All the things that we've
  • 46:22been learning, we've known, and
  • 46:23we've been learning. Because one
  • 46:24of the things that we
  • 46:25see at big cancer centers
  • 46:27all the time is that
  • 46:27someone comes in from the
  • 46:28community
  • 46:29and they're told, you know,
  • 46:31you can't do that or
  • 46:33that's unsafe, especially around the
  • 46:35more nuanced stuff.
  • 46:37And so in two thousand
  • 46:38and five, again, with the
  • 46:39support of my fearless mentor,
  • 46:41we started the program for
  • 46:43young women with breast cancer,
  • 46:44and now we call it
  • 46:45young adults with breast cancer.
  • 46:47And this program addresses the
  • 46:49critical issues that we've been
  • 46:50talking about today that are
  • 46:52unique to or accentuated by
  • 46:54being young. We now call
  • 46:55it young and strong,
  • 46:57and it has four pillars.
  • 46:58We focus on providing expert
  • 47:00medical care. That's kind of
  • 47:01what's unique to a big
  • 47:03cancer center compared to all
  • 47:04the advocates and all the
  • 47:05other people that are doing
  • 47:06really great space in this
  • 47:07work.
  • 47:08We offer comprehensive
  • 47:10support. We try to build
  • 47:12community among the young patients.
  • 47:14And then, of course, we
  • 47:15we conduct research to try
  • 47:16and inform
  • 47:17the care and the outcomes.
  • 47:19These are our newest program
  • 47:21introduction cards. We've you know,
  • 47:23we try and make it
  • 47:24pretty and appealing because there's
  • 47:25so much coming at people
  • 47:27every day from, you know,
  • 47:29the world, including the cancer
  • 47:30center, something that feels that
  • 47:32it's resonating with them. You
  • 47:33can see here.
  • 47:35We also create a number
  • 47:37of communications that are designed
  • 47:38just for them. We have
  • 47:39newsletters, e newsletters. We have
  • 47:41a website.
  • 47:42That's the web You can
  • 47:43Google it if you want
  • 47:43and send your patients there
  • 47:44because it is very I
  • 47:46think we have a lot
  • 47:46of really great webinars and
  • 47:46teaching sheets and things on
  • 47:46there, and it's just the
  • 47:47latest version of our newsletter.
  • 47:48We have a lot of
  • 47:50programming. Actually,
  • 47:56we do about fifty virtual
  • 47:59programs for our patients per
  • 48:01year. We've moved into supporting
  • 48:02our metastatic patients even more
  • 48:04nowadays
  • 48:05and have a virtual support
  • 48:07group for them as well
  • 48:08as for partners
  • 48:10of those patients because it's
  • 48:12so deep what they're dealing
  • 48:13with over time.
  • 48:15And so we try and
  • 48:16do a lot. We partner
  • 48:17with our social workers,
  • 48:18for that very important work,
  • 48:20a lot of sexual health
  • 48:21things, all the things that
  • 48:22are important to these patients.
  • 48:24We actually just were funded
  • 48:26through the CDC
  • 48:27to do
  • 48:28a contract
  • 48:29to better engage with our
  • 48:31communities
  • 48:32writ large around the Greater
  • 48:34Boston area so that we're
  • 48:35not just serving the people
  • 48:36that are able to get
  • 48:37into our Dana Farber clinics
  • 48:39and try and get more
  • 48:41information out more into the
  • 48:42community that we're calling that
  • 48:44the yes project, and we're
  • 48:45creating a bunch of resources
  • 48:47that we hope to partner
  • 48:48with groups like you so
  • 48:49that when we create these
  • 48:50things, there's no reason for
  • 48:51people to reinvent the wheel.
  • 48:53Hand it out, put your
  • 48:54Yale sticker on it. We're
  • 48:56happy to share so that
  • 48:57things are disseminated
  • 48:59everywhere it needs to be.
  • 49:01We're not competitors here at
  • 49:02all.
  • 49:05Final thing is we've also
  • 49:06tried to get our young
  • 49:07women,
  • 49:09our young, patient
  • 49:11supports
  • 49:12out beyond
  • 49:14beyond cancer centers, beyond clinics.
  • 49:17And we created something called
  • 49:18Young Empowered and Strong, the
  • 49:19web based portal,
  • 49:21which is a PRO based
  • 49:23text prompting
  • 49:25kind of tool
  • 49:26where if a woman endorses
  • 49:28signs or symptoms or concerns,
  • 49:31she gets information. You can
  • 49:32see here there's anxiety. Okay.
  • 49:34You're anxious.
  • 49:35Let's give her some more
  • 49:36information on managing anxiety. She's
  • 49:38interested in fertility around treatment.
  • 49:40Let's give her more information
  • 49:41on that. If she doesn't
  • 49:42endorse that as an issue,
  • 49:44she doesn't get the information
  • 49:45on that,
  • 49:46but she can ask for
  • 49:47it if she wants it.
  • 49:48And we did a pilot
  • 49:49of this. And as you
  • 49:50can see here, what do
  • 49:52the women trigger the most?
  • 49:53Well, actually, if you look
  • 49:54at the bottom, we're pretty
  • 49:55good at treating pain. We're
  • 49:57reasonably good at treating nausea,
  • 49:59but there was nearly universal
  • 50:01triggering
  • 50:02of things like sexual health,
  • 50:04menopausal symptoms, and mental health.
  • 50:06And that doesn't mean we
  • 50:07don't try, but there's a
  • 50:08lot of need there. And
  • 50:09so our hope, and we're
  • 50:11now testing this in a
  • 50:13number of studies, both at
  • 50:14Dana Farber and then at
  • 50:15MultiSites,
  • 50:16to use this tool for
  • 50:18our young adults, both at
  • 50:19diagnosis,
  • 50:21living with metastatic disease, and
  • 50:23survivors to try and do
  • 50:25more of a kind of
  • 50:27self management of some of
  • 50:29especially the stuff that's harder.
  • 50:30You know, we don't have
  • 50:30resources to take care of
  • 50:32all of this stuff, but
  • 50:33a lot of our young
  • 50:34patients can self manage and
  • 50:35self monitor these things. So
  • 50:37we hope that we're able
  • 50:38to move the needle in
  • 50:39terms of serving them
  • 50:40better through these kinds of
  • 50:41tools.
  • 50:42Stay tuned. The final thing
  • 50:44I'll tell you about is
  • 50:45something that we partner with
  • 50:46an advocacy group called Bright
  • 50:48Pink. They had a tool
  • 50:49called assess your risk that
  • 50:51would they had built
  • 50:52and was sitting there on
  • 50:53the web, and they got
  • 50:54out of the kind of
  • 50:55advocacy, and they're just fundraising
  • 50:57now. And they gave us
  • 50:58the tool, and we kinda
  • 51:00Dana Farberized it. And now
  • 51:02it's available
  • 51:03online
  • 51:04to go in for any
  • 51:06patient to look at their
  • 51:07risks of any woman. It
  • 51:08doesn't have to be a
  • 51:09patient. It's more for non
  • 51:10patients, people who are previvors,
  • 51:13and to look up their
  • 51:14breast and ovarian cancer risks
  • 51:16and put in their it's
  • 51:18both about health behaviors, it's
  • 51:19about family history,
  • 51:21and it's using,
  • 51:22tire, tear up music
  • 51:24and other kind of, you
  • 51:25know, things that are not
  • 51:26in there, but we all
  • 51:27know matter, like how much
  • 51:29alcohol and whether or not
  • 51:30they're exercising and whether or
  • 51:31not they're obese. And so
  • 51:33we've now activated that
  • 51:36website as of last year,
  • 51:37I think in January,
  • 51:39and we've had something like
  • 51:40a hundred thousand page views
  • 51:43and over almost seven thousand
  • 51:45unique views. And it's a
  • 51:46pretty cool tool. So if
  • 51:47anybody's interested in sending patients
  • 51:49there or wants more information,
  • 51:51it's it's a nice way
  • 51:52for people when they when
  • 51:53their friend is sitting next
  • 51:54to them and saying, what
  • 51:55do I need to know
  • 51:56about breast cancer? And you
  • 51:57don't have time, send them
  • 51:58to this and they can
  • 51:59kind of learn a little
  • 51:59more. And there's a lot
  • 52:00of teaching around it.
  • 52:02So in conclusion,
  • 52:04I
  • 52:05would hope we agree today
  • 52:07after all this that, younger
  • 52:08women do, unfortunately, still have
  • 52:10higher risk of recurrence and
  • 52:11mortality from breast cancer,
  • 52:13but there are a growing
  • 52:15number of tools to reduce
  • 52:16risk. All of the
  • 52:18advances that we've made recently,
  • 52:20like immunotherapy
  • 52:21for triple negative breast cancer
  • 52:23or the anti HER2 therapies,
  • 52:25if anything,
  • 52:26they're more likely to help
  • 52:28our youngest patients because they're
  • 52:29more likely to both develop
  • 52:30those kinds of diseases
  • 52:32proportionally
  • 52:33as well as
  • 52:34have more advanced disease that
  • 52:36warrant that level of treatment.
  • 52:38And so when over the
  • 52:40next several years, I hope
  • 52:41we continue to see improvements
  • 52:43in terms of their mortality
  • 52:44and recurrence risks.
  • 52:46But on the flip side,
  • 52:47I don't think we need
  • 52:48to treat all young women
  • 52:49with aggressive therapy, and we
  • 52:50need to continue to interpret
  • 52:52the data with a more
  • 52:54nuanced view so our patients
  • 52:55get their tailored therapy, not
  • 52:57the sledgehammer of chemo and
  • 52:59everything else, especially when, you
  • 53:01know, you could do it
  • 53:02with a more precise,
  • 53:04scalpel.
  • 53:05I think we do need
  • 53:06to continue focusing research,
  • 53:08on this population,
  • 53:10not just because I do
  • 53:11it but because the numbers
  • 53:13are increasing.
  • 53:14And we need to understand
  • 53:15better who's at high risk
  • 53:17and what's biologically unique about
  • 53:19this population,
  • 53:20if anything, so that we
  • 53:21can develop better tools to
  • 53:23target,
  • 53:24their disease.
  • 53:25And then finally,
  • 53:27focused efforts to implement what
  • 53:29we already know, whether it's
  • 53:31adherence or getting better information
  • 53:32about management of hot flashes
  • 53:34or vaginal dryness for this
  • 53:35population
  • 53:36that shouldn't really be dealing
  • 53:37with this at that age,
  • 53:39is, I think, critical to
  • 53:41taking better care of them.
  • 53:42And I know, you know,
  • 53:43we I just showed you
  • 53:44our Young and Strong program.
  • 53:45I know you guys are
  • 53:45doing great work here in
  • 53:47your Young Onset Cancer program
  • 53:49led by Nancy and Vida.
  • 53:51And so I'm I'm excited
  • 53:53about our ongoing collaborations
  • 53:54and all of that work.
  • 53:55And I'd like to end
  • 53:56with just saying thank you.
  • 53:57Thank you to all of
  • 53:58you for listening.
  • 53:59Thanks especially to Eric,
  • 54:02for supporting a lot of
  • 54:03this work and supporting me
  • 54:04over the years. And we
  • 54:05have, of course, funders, and
  • 54:07I have a whole team
  • 54:07of people I've been working
  • 54:08with for years both at
  • 54:09Dana Farber and beyond.
  • 54:11And then to me, it's
  • 54:12really important to always infuse
  • 54:14the patient voice into all
  • 54:15of this. So many, many
  • 54:17patients and advocates have, contributed
  • 54:19to a lot of the
  • 54:20work that, at least from
  • 54:21our group over the years.
  • 54:22So thank you.
  • 54:29We probably have time for
  • 54:30about two questions. Okay.
  • 54:36Quick question about the, positive
  • 54:38trial and
  • 54:40recommendations
  • 54:41you made in the trial
  • 54:42setting breastfeeding after the delivery.
  • 54:44That may have had any
  • 54:46interaction with the outbreaks?
  • 54:49So it's a great question.
  • 54:51And we just looked at
  • 54:52breastfeeding, and we just presented
  • 54:54it. And the people there
  • 54:55was no detriment to breastfeeding.
  • 54:58They didn't appear to also
  • 54:59be to add any good
  • 55:00goodness. There was no there
  • 55:02was no difference.
  • 55:04The numbers get small, though,
  • 55:06and there are a number
  • 55:07of studies that are looking
  • 55:08at this right now in
  • 55:09the cohorts that are available,
  • 55:10believe it or not. And
  • 55:11it looks very feasible for
  • 55:13a proportion of patients. I
  • 55:14mean, obviously, if they have
  • 55:15breast tissue, challenging on one
  • 55:17side, but didn't didn't clearly
  • 55:18impact on their breast cancer
  • 55:20outcomes.
  • 55:22Say they couldn't breast No.
  • 55:24We encouraged it.
  • 55:26Well, no. It was very
  • 55:27personal. So we encouraged it
  • 55:28if they wanted to, but
  • 55:29we wanted them to get
  • 55:30back on in within two
  • 55:31years. But that doesn't mean
  • 55:32that everybody listen. This is
  • 55:33a very practical real world
  • 55:35thing, and I had people
  • 55:36who kept breastfeeding and didn't
  • 55:37get back on. I mean,
  • 55:38it's just the nature of
  • 55:39the beast. So we'll be
  • 55:40able to look at that
  • 55:41over time, but the short
  • 55:42term data using that same
  • 55:44forty one months,
  • 55:45it didn't hurt or harm.
  • 55:49It's a good question.
  • 55:55Oh
  • 55:56oh, here. View. Let's see.
  • 55:59Do we
  • 56:01uncheck? Okay. Sorry. I'm Melissa.
  • 56:06Do you see it?
  • 56:09It just says, Andrew, can
  • 56:10you share your question via
  • 56:11chat? I don't know what
  • 56:13happened. Did you have a
  • 56:14question, Mary?
  • 56:17Positive data are being
  • 56:19twisted
  • 56:20among
  • 56:22certain circles
  • 56:23as,
  • 56:25that estrogen replacement therapy
  • 56:27and postmenopausal
  • 56:28years
  • 56:29that this is proof
  • 56:31that estrogen is not associated
  • 56:33with increased breast cancer. Like,
  • 56:34again, this this can you're
  • 56:36you're being cited in circles
  • 56:37you may not be aware
  • 56:38of.
  • 56:39People think I'm gonna be
  • 56:40the baby whisperer. And sometimes
  • 56:41people come to me, and
  • 56:42I'm like, you can't have
  • 56:43a baby right now.
  • 56:46Yeah. I think it's a
  • 56:47great question.
  • 56:49And if if anybody didn't
  • 56:50hear it, it's can we
  • 56:51use the positive data to
  • 56:52justify
  • 56:53the free for all that
  • 56:55we want? People are like,
  • 56:56oh, I can just take
  • 56:56a two year break in
  • 56:57my endocrine therapy, or I
  • 56:59can just add any hormone
  • 57:01back because positive showed I
  • 57:02could have a baby. And
  • 57:03I think the answer is
  • 57:05positive showed
  • 57:06in short term follow-up that
  • 57:08there was no clear short
  • 57:10term detriment to an interruption
  • 57:12for pregnancy. And the majority
  • 57:14of these people had a
  • 57:15pregnancy,
  • 57:16some didn't. And, yeah, there's
  • 57:18a little signal for a
  • 57:19pregnancy might be a good
  • 57:20thing, but it may all
  • 57:21be healthy mother bias who's
  • 57:23able to get pregnant. The
  • 57:23body is funky. Right? Maybe
  • 57:25the body doesn't get pregnant
  • 57:26when it's having a recurrence
  • 57:28that you don't even know
  • 57:28about yet. So we just
  • 57:30don't know. I would say
  • 57:31long term, I would watch
  • 57:32it, but I would not
  • 57:33use it for a justification
  • 57:35of anything else.
  • 57:38It's a good question.
  • 57:41Alright. Well Thank you.
