- 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.
