- 00:06Welcome to Yale Cancer Answers
- 00:08with the director of the
- 00:09Yale Cancer Center, Doctor Eric Winer.
- 00:12Yale Cancer Answers features conversations
- 00:14with oncologists and specialists who
- 00:16are on the forefront of
- 00:17the battle to fight cancer.
- 00:19This week, it's a conversation
- 00:20about some of the decisions
- 00:22patients are faced with in
- 00:23the treatment of breast cancer
- 00:24with doctor Sarah Schellhorn.
- 00:26Doctor Schellhorn is an associate
- 00:28professor of medicine and medical
- 00:29oncology at the Yale School
- 00:31of Medicine.
- 00:32Here's doctor Winer.
- 00:34I know that
- 00:36over the course of the
- 00:38past decade plus, you have
- 00:40taken care of
- 00:41countless
- 00:43women with breast cancer.
- 00:47And some of those are
- 00:48young women.
- 00:50As people know, breast cancer
- 00:52affects women of all ages.
- 00:53It becomes more common
- 00:55as women grow older, but
- 00:57it
- 00:58is a cancer that's pretty
- 01:00common in younger women too.
- 01:03And so issues about fertility
- 01:06come up.
- 01:07They sure do.
- 01:08And,
- 01:09maybe you could just, you
- 01:11know, start with a few
- 01:12thoughts
- 01:13about
- 01:14how you approach those conversations
- 01:16with patients.
- 01:18It's always a challenge
- 01:20when you're meeting a patient
- 01:21for the first time and
- 01:24they've been given this
- 01:26new diagnosis of breast cancer,
- 01:28and there are lots of
- 01:29things that have to be
- 01:30talked about regarding the new
- 01:32cancer, regarding the treatment, regarding
- 01:34all the options. You've got
- 01:36surgical options and medication options
- 01:39radiation options, and it
- 01:41can all be overwhelming.
- 01:44But it's really important to
- 01:46remember
- 01:47that young women in particular,
- 01:50may not have completed their
- 01:52families. They may not have
- 01:56had children or as many
- 01:58children as they would want.
- 01:59They may have
- 02:01plans, and they may have
- 02:02been putting things off for
- 02:03career or other reasons.
- 02:05And those are NOTE Confidence: 0.9790995
- 02:06critical lifestyle
- 02:08pieces
- 02:09that we have to consider
- 02:11in the treatment of
- 02:12breast cancer. So
- 02:14when I see a new
- 02:15patient
- 02:16that I have a little
- 02:17bit of a mental checklist,
- 02:19that I go through
- 02:21that's
- 02:22certainly talk about the cancer,
- 02:23talk about the reasons for
- 02:25various treatments, and the reasons
- 02:27why things are being recommended.
- 02:29But we also wanna make
- 02:30sure that we're taking into
- 02:31account,
- 02:32is your family complete? Have
- 02:34you ever thought about having
- 02:35children? Because a lot of
- 02:36the treatments that we use
- 02:37in the treatment of breast
- 02:38cancer
- 02:39can affect
- 02:41someone's future fertility.
- 02:43They may prevent someone from
- 02:45being able to carry a
- 02:46healthy pregnancy
- 02:48if they were to become
- 02:49pregnant while on these medications.
- 02:51So these are critical conversations
- 02:53that have to happen.
- 02:59And they can effect fertility in different ways.
- 03:01Chemotherapy, for example.
- 03:03Chemotherapy,
- 03:05as I think many of
- 03:06our listeners know,
- 03:08can
- 03:09put a woman into menopause.
- 03:11Yes.
- 03:12But
- 03:13that's not always the case,
- 03:15and it's very much age
- 03:16related.
- 03:17Yes.
- 03:19Talk about that a little
- 03:20bit. I mean, if
- 03:21you're a twenty five
- 03:23year old, are you gonna
- 03:24go into menopause with chemotherapy?
- 03:26You may go into
- 03:27a temporary menopause, and you
- 03:28may have hot flashes and
- 03:29be kind of uncomfortable from
- 03:31a menopausal standpoint
- 03:33for a short period of
- 03:34time. But in all likelihood,
- 03:37a twenty five year old
- 03:38has very robust ovaries that
- 03:40are gonna kick it back
- 03:41into gear
- 03:42within a few months from
- 03:44completing chemotherapy.
- 03:46The older a woman is
- 03:47and the closer to natural
- 03:49menopause,
- 03:50the less likely
- 03:52that they will regain fertility.
- 03:55But a twenty five year
- 03:56old, a thirty year old,
- 03:57very likely to be
- 03:59able to
- 04:02have menstrual
- 04:04cycles again, may be able
- 04:05to become pregnant. And there
- 04:07are even things that we
- 04:08can do during chemotherapy
- 04:10that can help preserve fertility.
- 04:12And what are those things?
- 04:16I feel like you might
- 04:17know the answer to this
- 04:18question, but
- 04:20you can actually
- 04:22use medications
- 04:24called GnRH agonists. They're
- 04:26shots, injections that
- 04:29effectively put the ovaries to
- 04:31sleep, kind of put them
- 04:32into a dormant
- 04:34status so that the chemotherapy
- 04:36doesn't affect them as much.
- 04:38And
- 04:39studies have shown that women
- 04:41who receive
- 04:43these additional treatments during chemotherapy
- 04:46are more likely to go
- 04:48on and carry healthy pregnancies
- 04:51in the future.
- 04:52So we use those a lot
- 04:53in people who desire future
- 04:54fertility.
- 04:55So that's one option
- 04:57during chemotherapy itself.
- 05:02But you also have to remember
- 05:03when someone is
- 05:05undergoing chemotherapy and their
- 05:07ovaries are a certain age,
- 05:09whatever that age is,
- 05:12those ovaries are not getting
- 05:13any younger, and any eggs
- 05:15that are contained in those
- 05:16ovaries aren't getting any younger.
- 05:18And so even when we
- 05:20try to
- 05:21preserve someone's fertility by using
- 05:23these injections,
- 05:25we still may advise
- 05:27them to preserve eggs or
- 05:29embryos if they're in a
- 05:30committed relationship
- 05:34to enhance the options of
- 05:36having a healthy baby, healthy
- 05:38pregnancy
- 05:39down the line. Because
- 05:40the older an ovary gets,
- 05:41the older the egg gets,
- 05:43the more chances that
- 05:46genetically, a baby may have
- 05:48more problems.
- 05:50Well in
- 05:52my former institution before I
- 05:54came to Yale a few
- 05:55years ago,
- 05:57we had started a program for
- 06:00young women with breast cancer,
- 06:03something that we're actually starting
- 06:06at Smilow,
- 06:07for not just young women
- 06:09with breast cancer, but young
- 06:10people with cancer in general.
- 06:12But the reason I bring
- 06:14this up is that
- 06:15initially,
- 06:16we set
- 06:17the cut point for age
- 06:19at forty two.
- 06:22It eventually snuck up a
- 06:23little bit as the person
- 06:24who was directing that program
- 06:27also got a little older.
- 06:29But the reason we picked
- 06:31forty two is that
- 06:33that was probably an
- 06:35age where there aren't a
- 06:36lot of people who are
- 06:38still
- 06:38thinking about becoming pregnant after
- 06:41that age.
- 06:42And while there may be
- 06:43a few,
- 06:45our options
- 06:46are much more limited.
- 06:48But,
- 06:50the other complicating
- 06:52feature is that we also
- 06:54sometimes
- 06:55suppress
- 06:56the function of ovaries
- 06:58as part of treatment for
- 07:00breast cancer.
- 07:01Or we use medications
- 07:03that are
- 07:05contraindicated.
- 07:06They can't be given during
- 07:07pregnancy because they cause fetal
- 07:09abnormalities.
- 07:11And these are
- 07:12the hormone based treatments or
- 07:15probably more appropriately anti hormone,
- 07:17antiestrogens.
- 07:21So depending on whatever clinical circumstance,
- 07:23we might put someone into
- 07:25menopause,
- 07:26in which case they can't
- 07:27become pregnant naturally,
- 07:29if they're in menopause. Their
- 07:31ovaries are not functioning.
- 07:33Or we use a drug
- 07:34called tamoxifen,
- 07:36which cannot be given during
- 07:38pregnancy.
- 07:39And these are given for
- 07:40a long time. They're given
- 07:41for at least five years
- 07:44in many cases,
- 07:46assuming they're well tolerated.
- 07:48And that's five years of
- 07:50time
- 07:51where ovaries are also getting
- 07:53older and eggs that are
- 07:54in the ovaries are getting
- 07:55older. So it may become
- 07:57just because of
- 07:59normal, natural
- 08:00history of a woman's fertility,
- 08:02it may be harder to
- 08:03become pregnant after five years
- 08:04of endocrine therapy.
- 08:06So I'm not
- 08:08sure if this is where
- 08:09you were pointing
- 08:10our conversation, but
- 08:12there's a
- 08:13study called the positive study,
- 08:16designed, I think, primarily by
- 08:18people at your former institution,
- 08:23that looked at discontinuing
- 08:25endocrine therapy, tamoxifen
- 08:27or others,
- 08:28earlier than the five years.
- 08:30So women had to be
- 08:31on that medication for
- 08:34at least eighteen months, but
- 08:36could be longer.
- 08:38And the medication was
- 08:39discontinued in an effort to
- 08:41have them achieve
- 08:43a normal pregnancy, either
- 08:45through natural
- 08:47means or through
- 08:49additional fertility treatments.
- 08:51And so far, the results
- 08:53from that study have been
- 08:54incredibly
- 08:56positive, incredibly
- 08:58optimistic
- 08:59that women can
- 09:01stop endocrine therapy,
- 09:03have a pregnancy, deliver a
- 09:05baby, even breastfeed for a
- 09:06little bit, and then go
- 09:08back on endocrine therapy with
- 09:10no detrimental effects to their
- 09:12ultimate outcome, although we're still
- 09:13waiting for long term
- 09:15follow-up of this study.
- 09:17And and, of course, we
- 09:18couldn't do the ultimate study,
- 09:21which would be to randomize
- 09:22patients because it's pretty hard
- 09:24to
- 09:25randomize someone to get pregnant
- 09:27or you don't get pregnant.
- 09:28That's a tough thing to do.
- 09:31That's not one
- 09:32that can be done.
- 09:34What was interesting about the
- 09:36results from the study too
- 09:37is that,
- 09:39about three quarters of the
- 09:41women, if I remember correctly,
- 09:43actually
- 09:44were able to become pregnant
- 09:46and deliver a child,
- 09:48which is a remarkably
- 09:50high percentage.
- 09:52It is, especially given that
- 09:54a fair number of those
- 09:55women got chemotherapy,
- 09:57so really reassuring,
- 09:59and I think opens a
- 10:01lot of doors
- 10:02that we previously would have
- 10:04considered closed
- 10:06for younger women with breast
- 10:08cancer.
- 10:10It does seem that
- 10:12as complicated as this dance is around
- 10:16breast cancer treatment and pregnancy,
- 10:18that there's often a way
- 10:20to navigate
- 10:22a result that is gonna
- 10:24both be optimal
- 10:26in terms of treating the
- 10:27cancer and will also give
- 10:29somebody the chance to have
- 10:30a child if that's what
- 10:31they really wanna do.
- 10:33It's a careful conversation.
- 10:36It's a long conversation.
- 10:39It can be a really
- 10:40emotional and intense conversation,
- 10:43because
- 10:44pretty
- 10:45far reaching ramifications for a
- 10:47woman's future. But
- 10:50we are often able to
- 10:52navigate
- 10:54chemotherapy,
- 10:55fertility treatments prior to chemotherapy.
- 10:58And even when someone needs
- 10:59to be on endocrine therapy
- 11:00long term,
- 11:03getting a woman to a
- 11:04point where she can try
- 11:06to naturally
- 11:07have a child or
- 11:09with some medical help have
- 11:11a child.
- 11:12And for our listeners,
- 11:15it is worth pointing out
- 11:16that years ago, meaning twenty,
- 11:18thirty years ago,
- 11:20it was
- 11:21widely assumed that getting pregnant
- 11:24after breast cancer
- 11:25was something that you always
- 11:27wanted to avoid because the
- 11:28pregnancy could stimulate a recurrence.
- 11:31And that really doesn't seem
- 11:33to be the case.
- 11:34In the data we have
- 11:38it has never really been shown. In fact, it
- 11:40hasn't been shown.
- 11:42That's right. So I think
- 11:43we're in a
- 11:44much better place. We
- 11:46also now
- 11:47can not only preserve embryos,
- 11:50but if someone doesn't have
- 11:51a partner,
- 11:52we can save
- 11:54eggs, eggs or pieces
- 11:56of ovarian tissue, all kinds
- 11:58of different things,
- 12:00that fertility specialists have at
- 12:02their fingertips to be able to help.
- 12:06Again, nothing's a
- 12:07hundred percent, but lots of
- 12:09options that can be explored.
- 12:11And I think this
- 12:12is another example of the
- 12:13fact that
- 12:14you often need
- 12:16doctors
- 12:18and nurses and others from
- 12:19many different fields to provide
- 12:21optimal care.
- 12:23And as medical oncologists,
- 12:26we're not the ones prescribing
- 12:28fertility treatments
- 12:30and we need to work
- 12:31with our our colleagues in
- 12:34OB GYN.
- 12:37The treatment of breast cancer,
- 12:38the treatment of any cancer,
- 12:39requires a lot of
- 12:40hands on deck,
- 12:42and close connections with
- 12:44lots of different disciplines and
- 12:45fields,
- 12:47to be able to provide
- 12:48truly comprehensive
- 12:50whole patient care.
- 12:52I just wanna come
- 12:53back in our
- 12:55last
- 12:56few seconds before the break
- 12:58and
- 12:59just touch very briefly on
- 13:01the fact that
- 13:03we all recognize this is
- 13:04an emotionally charged
- 13:06experience. I mean, having cancer
- 13:08is hard enough. Having cancer
- 13:10and worrying about wanting to
- 13:12become pregnant or maybe even
- 13:14being pregnant at the time
- 13:15just makes it that much
- 13:16harder.
- 13:20It's hard enough,
- 13:22to have to have these
- 13:23conversations about treatment. And you
- 13:25throw
- 13:27fertility and families
- 13:28into it,
- 13:30it is that much harder.
- 13:31Well, we're gonna take just a
- 13:34very brief break, and I'll
- 13:36return in
- 13:38just a minute with doctor
- 13:39Sarah Schellhorn,
- 13:41associate professor at Yale School
- 13:43of Medicine, and we'll continue
- 13:45our conversation about
- 13:48other issues related to breast
- 13:49cancer.

- 14:08The American Cancer Society estimates
- 14:10that over two hundred thousand
- 14:12cases of melanoma will be
- 14:13diagnosed in the United States
- 14:15this year, with over a
- 14:16thousand patients in Connecticut alone.
- 14:19While melanoma
- 14:20accounts for only about one
- 14:22percent of skin cancer cases,
- 14:24it causes the most skin
- 14:26cancer deaths, but when detected
- 14:28early it is easily treated
- 14:29and highly curable.
- 14:31Clinical trials are currently underway
- 14:33at federally designated comprehensive cancer
- 14:35centers such as Yale Cancer
- 14:37Center and at Smilow Cancer
- 14:39Hospital
- 14:40to test innovative new treatments
- 14:41for melanoma.

- 15:00You're listening to Connecticut Public
- 15:02Radio.
- 15:04Hello again. This is Eric
- 15:06Winer from the Yale Cancer
- 15:08Center here with Yale Cancer Answers.
- 15:11And I'm joined tonight by
- 15:13doctor Sarah Schellhorn, associate professor
- 15:15of medicine
- 15:16and a breast cancer expert.
- 15:19We spent the last
- 15:21fifteen minutes or so talking
- 15:22about pregnancy and breast cancer.
- 15:25We're gonna move on and
- 15:26talk about other hormonal aspects
- 15:28of breast cancer or in
- 15:30particular,
- 15:31hormonal or anti hormonal treatments.
- 15:35These are given to
- 15:37a large number of women
- 15:39with breast cancer
- 15:40because
- 15:41somewhere in the range of
- 15:43in excess of seventy
- 15:46five percent of all breast
- 15:47cancers
- 15:49are sensitive to female reproductive
- 15:51hormones.
- 15:53Sarah,
- 15:54maybe you could
- 15:56just talk about
- 15:58generally the benefits
- 16:00of
- 16:01these anti hormonal treatments and
- 16:04perhaps describe the two most
- 16:07common ones that we use
- 16:09to help prevent recurrences.
- 16:10Sure.
- 16:12So it's really interesting.
- 16:13I think there's a kind
- 16:14of an interesting historical piece to
- 16:19the treatment of breast cancer.
- 16:20If you think back, and
- 16:21I can't give you
- 16:22an exact date, but many
- 16:24decades
- 16:25ago,
- 16:27the treatment of breast cancer
- 16:29was pretty morbid, lots of
- 16:30big surgeries. There were some
- 16:32studies of chemotherapy. But what
- 16:34was discovered was some
- 16:37in many women with breast
- 16:38cancer,
- 16:39taking out their ovaries and
- 16:41putting them into menopause seemed
- 16:43to be a pretty good
- 16:43treatment for breast cancer. And
- 16:45it was on that
- 16:47further studies showed that
- 16:50many breast cancers, as you
- 16:52said,
- 16:53probably more than three
- 16:54quarters of all breast cancers,
- 16:56express
- 16:57the estrogen receptor or the
- 16:59progesterone receptor.
- 17:01And these are
- 17:02hormone
- 17:04receptors that require
- 17:06kind of seeing the hormone,
- 17:07estrogen or progesterone,
- 17:09that leads to cells,
- 17:11cancer cells in particular,
- 17:13getting the signals they need
- 17:15to grow and divide.
- 17:16And so these cancers are,
- 17:18in essence, fueled by hormones.
- 17:21And
- 17:23a number of different types
- 17:25of drugs have been developed
- 17:26that work on that interaction
- 17:31between the hormone and its
- 17:32receptor.
- 17:33The oldest is a drug
- 17:35called tamoxifen,
- 17:36which
- 17:38is a competitive
- 17:40antagonist in the breast
- 17:41of estrogen. All that means
- 17:43is if we think about
- 17:44a receptor kind of like
- 17:45a baseball glove
- 17:47and we think about the
- 17:48hormone like a baseball and
- 17:49the glove catches the
- 17:51baseball,
- 17:52tamoxifen
- 17:53is kind of like a
- 17:54grapefruit.
- 17:55And if you're holding it running
- 17:57around in the outfield of
- 17:58a baseball field, holding a
- 17:59grapefruit in your baseball glove,
- 18:00you're never gonna be able
- 18:01to catch a baseball. It's
- 18:02kind of how I describe
- 18:03it to patients.
- 18:06But
- 18:07Tamoxifen blocks that as the result.
- 18:08Great way of describing
- 18:10it and for listeners it actually even
- 18:12works without seeing your hands.
- 18:15I've got some
- 18:16really great hand gestures going
- 18:17on right now.
- 18:18It then leads into a big conversations about
- 18:20baseball teams
- 18:22and Yankees and
- 18:23Red Sox, but I won't
- 18:25go there. But,
- 18:27tamoxifen,
- 18:28when it's given for
- 18:30five years, maybe longer,
- 18:32has been shown to reduce
- 18:34the chances of a breast
- 18:35cancer coming back by about
- 18:38half, by a
- 18:40relative
- 18:41risk reduction of fifty percent.
- 18:44And if we can just
- 18:45say for a minute what
- 18:46that means in people's
- 18:48terms.
- 18:49So if you have a
- 18:52ten percent chance of having
- 18:53a recurrence, it goes down
- 18:55to about five. If
- 18:56you have a twenty five
- 18:58percent chance of having a
- 19:00recurrence of your cancer, because
- 19:01it's a higher risk cancer,
- 19:03it would go down to
- 19:04twelve and a half percent.
- 19:06Right.
- 19:07It's pretty powerful treatments.
- 19:11Arguably it is the first
- 19:12real personalized
- 19:14targeted therapy in cancer.
- 19:18So tamoxifen's been around for
- 19:20years and years and years.
- 19:24And it's got sort of
- 19:25a bad rap.
- 19:27Why is that?
- 19:28I think
- 19:29with the advent of social
- 19:31media and online
- 19:33web based
- 19:34chat groups, there's a lot
- 19:36of information sharing.
- 19:38And
- 19:39tamoxifen does have some potential
- 19:41side effects. It can cause
- 19:43hot flashes. It can cause
- 19:44mood changes. It can cause
- 19:46fluid retention and weight gain
- 19:48and cause people to not
- 19:49feel
- 19:50terribly normal, causes headaches.
- 19:52Lots of things that
- 19:55are maybe not horrible from
- 19:57a medical standpoint, but from
- 19:59a lifestyle
- 20:00quality of life standpoint can
- 20:02be really
- 20:03problematic.
- 20:05But many women
- 20:07tolerate the pill just fine.
- 20:09And
- 20:10when we think about who
- 20:12are the
- 20:13loudest people on these web
- 20:15based chat groups, often it's
- 20:17the people who are having
- 20:18the problems,
- 20:20that
- 20:22appropriately,
- 20:23are asking for help and
- 20:24asking for advice.
- 20:27And the people who are
- 20:27doing just fine
- 20:29are living their lives and it
- 20:33tends to be a little
- 20:35bit more problematic in younger
- 20:36women than older women. So
- 20:39you put
- 20:40a thirty five year old
- 20:41woman on Tamoxifen,
- 20:43and at least in
- 20:44my practice,
- 20:45I tend to expect a
- 20:47few more symptoms than I
- 20:49would in somebody twenty years
- 20:50older.
- 20:51And I think it's
- 20:53important to remember
- 20:54that estrogen and progesterone
- 20:57really do serve a purpose
- 20:58in women.
- 21:00And
- 21:01messing around,
- 21:03manipulating
- 21:04hormones,
- 21:06can cause problems and
- 21:08and big ones that really
- 21:10impact somebody's
- 21:13day to day.
- 21:14Hot flashes, if they happen
- 21:16only once every few days,
- 21:17probably not that big a
- 21:18deal. But hot flashes that
- 21:20are happening ten times a
- 21:21night and preventing somebody from
- 21:22sleeping and
- 21:24leads to chronic fatigue and
- 21:26mental fogginess, that's
- 21:28really a big deal.
- 21:30And so a lot of
- 21:31the conversations that we have
- 21:32in clinic
- 21:34relate to that absolute
- 21:36benefit
- 21:37conversation
- 21:38and the relative
- 21:39benefit. So, yes, while tamoxifen
- 21:41reduces the chances of a
- 21:42cancer
- 21:43recurring by fifty percent,
- 21:46if someone's risk of a
- 21:47cancer recurring is really small,
- 21:50the benefit of tamoxifen is
- 21:52also really small.
- 21:54And for many women,
- 21:55it may not be enough to
- 22:00warrant staying on a medication
- 22:01that makes them miserable.
- 22:03Absolutely, and
- 22:05there are alternatives to
- 22:07tamoxifen as well.
- 22:10So there's another class of
- 22:12medicines called aromatase inhibitors.
- 22:16Going back to my baseball
- 22:17analogy,
- 22:18aromatase inhibitors basically remove all
- 22:20the baseballs. So you can't
- 22:21catch a baseball
- 22:23if there are no baseballs
- 22:24to be caught. It
- 22:26basically prevents
- 22:28a woman from being able
- 22:30to make estrogen.
- 22:32It has to be given
- 22:34in conjunction with other medicines
- 22:36in very young women who
- 22:38have ovarian function.
- 22:41So that gets a little
- 22:42bit more complicated.
- 22:44But
- 22:45these medicines reduce estrogen levels
- 22:48from
- 22:49a low level
- 22:50to a very low level,
- 22:52almost
- 22:53undetectable level.
- 22:56I was just gonna jump
- 22:57in and say, you use
- 22:58the baseball,
- 23:00metaphor. I typically
- 23:02describe
- 23:03giving one of these
- 23:05medicines
- 23:06along with suppressing ovarian function,
- 23:09which is what we have
- 23:09to do when we do
- 23:10it in a young woman,
- 23:13as
- 23:14entering menopause by jumping off
- 23:16the high dive
- 23:18instead of instead of wading
- 23:19into the water.
- 23:21It's not
- 23:22a slow process. It's not
- 23:24a natural process.
- 23:25That's not what normally happens.
- 23:29So the side effects of
- 23:30those aromatase inhibitors
- 23:32is just kind of like
- 23:33menopause only more so.
- 23:36And you think about
- 23:38putting somebody
- 23:40who has normal
- 23:42ovaries, whose
- 23:44normal ovarian function has
- 23:47fluctuating levels of hormones
- 23:49and has normal menstrual cycles
- 23:51into menopause
- 23:52is like
- 23:54jumping in from the high
- 23:55dive or going from sixty
- 23:56miles an hour down to
- 23:58zero,
- 23:58it can be very jarring.
- 24:00And what's funny is for
- 24:01some people,
- 24:02it's associated with almost no
- 24:04symptoms.
- 24:05And for other people
- 24:07and I don't know
- 24:08how to predict this, it's
- 24:10just miserable.
- 24:11I hope someday we
- 24:14get to a point where
- 24:15we're able to
- 24:17predict how someone is going
- 24:19to feel. And I don't
- 24:20know what we'll use to
- 24:21predict that. Maybe
- 24:23there will be some
- 24:25smart
- 24:26genome technology. Maybe there will
- 24:28be some prior menstrual history
- 24:30piece to all of this,
- 24:31but that's a
- 24:33hard conversation to have. The
- 24:35only way to know if
- 24:35someone's gonna have side effects
- 24:37is for them to try
- 24:38it and see what happens.
- 24:40And I think the
- 24:41point you made that, you
- 24:42know, we give these medicines
- 24:44for a long time. So
- 24:45these are symptoms that may
- 24:47not be life threatening, but
- 24:48they're pretty annoying. And so
- 24:51putting up with them for
- 24:53a number of years for
- 24:54many women is often
- 24:56challenging
- 24:57to say the least.
- 24:58Now,
- 25:00on the other hand, these
- 25:02hormonal,
- 25:03antihormonal,
- 25:04endocrine therapies, they're called all
- 25:06of these different things,
- 25:08sometimes,
- 25:09are far more beneficial than
- 25:11treatments like chemotherapy,
- 25:13and it all depends on
- 25:14the tumor.
- 25:16That's exactly right.
- 25:19Breast cancer isn't one disease.
- 25:21And it's this big spectrum
- 25:24of diseases,
- 25:26each of which is treated
- 25:28a little bit differently
- 25:29or even a lot bit
- 25:30differently.
- 25:32We make decisions based on
- 25:34a few things that the
- 25:34pathologist tells us when they
- 25:36look at the cancer under
- 25:37the microscope. We look at
- 25:38the grade of the cancer.
- 25:40That's a measure of how
- 25:41aggressive the cells look under
- 25:42the microscope.
- 25:43We look at the
- 25:45percent of cells that have
- 25:46the estrogen receptor or the
- 25:47progesterone receptor.
- 25:49And then there's this may
- 25:50be where you were going
- 25:51with this question, but
- 25:53there's this test called the
- 25:55Oncotype test,
- 25:57which is
- 25:59a test of a patient's
- 26:01individual cancer.
- 26:03It looks at twenty one
- 26:05cancer
- 26:06related genes,
- 26:08and it looks at the
- 26:08levels of those genes and
- 26:10what levels they're expressed at.
- 26:12And based on the
- 26:13levels of those genes, it
- 26:14goes into this very complicated
- 26:17algorithm,
- 26:18that some very smart people
- 26:19developed many years ago. And
- 26:21then it spits
- 26:23out
- 26:24a number. And so you
- 26:26often,
- 26:27in breast cancer circles, you
- 26:29may have people saying, well,
- 26:30what was your number? What
- 26:31was your number?
- 26:32The recurrent score is a
- 26:33number, and it's on a
- 26:34scale of zero to a
- 26:36hundred.
- 26:37Most breast cancers
- 26:39have low numbers under fifty.
- 26:42And then depending on that
- 26:44recurrent score,
- 26:45we can help
- 26:47decide whether somebody
- 26:49needs chemotherapy or benefits from
- 26:51chemotherapy or really doesn't benefit
- 26:53from chemotherapy.
- 26:54And a
- 26:55couple of major studies
- 26:57that have been published in
- 26:58the last
- 26:59five, seven years,
- 27:02have shown that
- 27:04oncotype recurrence scores of
- 27:06twenty five or lower
- 27:08are not associated
- 27:10with much benefit to
- 27:12chemotherapy. There are some caveats
- 27:13to that. There are
- 27:15some questions
- 27:16in young women in particular.
- 27:18But in most women,
- 27:20low oncotypes,
- 27:23then don't benefit
- 27:24much from chemotherapy, if at
- 27:26all.
- 27:27And it's so different from
- 27:29the way it was thirty
- 27:30years ago where, in fact,
- 27:32it was one size fits all.
- 27:34Right. And, you know,
- 27:35we didn't differentiate between different
- 27:38cancers. We gave everybody
- 27:40essentially the same treatment,
- 27:42and
- 27:43it's
- 27:44come
- 27:45so very far. And at
- 27:48the same time,
- 27:50not only are we able
- 27:51to
- 27:53allow people to live with
- 27:54fewer side effects,
- 27:56but
- 27:57we're certainly doing no worse
- 27:59in terms of overall outcomes.
- 28:00And
- 28:01I think just as a
- 28:03sort of
- 28:04give people a general sense,
- 28:06what proportion of women who
- 28:08have breast cancer go on
- 28:09and live a normal
- 28:11life afterwards?
- 28:13A large proportion,
- 28:15eighty, eighty five percent go
- 28:17on and never
- 28:18hear back from this cancer,
- 28:20from their original cancer.
- 28:21And even women
- 28:23who do hear back from
- 28:24the cancer,
- 28:26whose cancer comes back
- 28:27whether in the breast or
- 28:29somewhere else, go on to
- 28:30live
- 28:31many, many years because of
- 28:33the advances in treatment.
