- 00:17 --> 00:19Welcome to Yale Cancer Answers with
- 00:19 --> 00:21your host Doctor Anees Chagpar.
- 00:21 --> 00:23Yale Cancer Answers features the
- 00:23 --> 00:25latest information on cancer care
- 00:25 --> 00:27by welcoming oncologists and
- 00:27 --> 00:29specialists who are on the
- 00:29 --> 00:31forefront of the battle to fight
- 00:31 --> 00:32cancer. This week it's a
- 00:32 --> 00:33conversation about neuropsychology
- 00:33 --> 00:35and brain cancer with doctor
- 00:35 --> 00:37Franklin Brown. Doctor Brown is an
- 00:37 --> 00:39assistant professor of neurology
- 00:39 --> 00:41and chief of the division of
- 00:41 --> 00:43neuropsychology at the Yale School
- 00:43 --> 00:45of Medicine where Doctor Chagpar
- 00:45 --> 00:47is a professor of surgical
- 00:47 --> 00:49oncology.
- 00:49 --> 00:52Dr. Brown, maybe we can start
- 00:52 --> 00:55off by you telling us a little bit
- 00:55 --> 00:57about what exactly is neuropsychology,
- 00:57 --> 00:59and how does that
- 00:59 --> 01:02interface with the world of cancer?
- 01:02 --> 01:04Neuropsychology is really
- 01:04 --> 01:06the study of cognition.
- 01:06 --> 01:07Things like memory,
- 01:07 --> 01:09attention span, language skills,
- 01:09 --> 01:11visual spatial skills,
- 01:11 --> 01:13all these different things that
- 01:13 --> 01:16your brain does on a daily basis to
- 01:16 --> 01:19basically think and talk and interact.
- 01:19 --> 01:22So that's basically what the field
- 01:22 --> 01:24looks at within brain tumors.
- 01:24 --> 01:26It's important because it helps assess
- 01:26 --> 01:29the impact of brain tumors on cognition,
- 01:29 --> 01:32but we can also use it to predict
- 01:32 --> 01:35in some cases what might happen
- 01:35 --> 01:38if the tumor is removed,
- 01:38 --> 01:40and it also might help guide
- 01:40 --> 01:43various methods of removal in
- 01:43 --> 01:45some cases so it can help guide
- 01:45 --> 01:48the impact of the tumor removal,
- 01:48 --> 01:50but also help the patient
- 01:50 --> 01:52and health care providers understand
- 01:52 --> 01:54the impact after it happens
- 01:54 --> 01:56and also help guide therapies.
- 01:56 --> 01:59And I can imagine that if somebody is
- 01:59 --> 02:00diagnosed with a brain tumor,
- 02:00 --> 02:02I mean just the concept and
- 02:02 --> 02:05the words itself makes you think, Oh my gosh,
- 02:05 --> 02:07what's going to happen?
- 02:08 --> 02:11Am I going to be able to think,
- 02:11 --> 02:13am I going to lose my IQ?
- 02:13 --> 02:16Am I going to be able to speak?
- 02:18 --> 02:21I'd imagine that there are a lot of
- 02:21 --> 02:24factors that go into that in terms of
- 02:24 --> 02:27where in the brain is this tumor and
- 02:27 --> 02:31what part of the brain does it affect?
- 02:31 --> 02:33Tell us a little bit more about
- 02:33 --> 02:36how you do that and how you
- 02:36 --> 02:38help patients and clinicians
- 02:38 --> 02:41get a sense of what this brain
- 02:41 --> 02:43tumor is doing and what
- 02:43 --> 02:46the ramifications of treatment are.
- 02:46 --> 02:48As you can imagine,
- 02:48 --> 02:50there all kinds of brain
- 02:50 --> 02:53tumors and they are discovered in
- 02:53 --> 02:54different ways. One way that
- 02:54 --> 02:58my field tends to interact a lot with brain
- 02:58 --> 02:59tumors can be from seizures.
- 02:59 --> 03:01In epilepsy there are some patients that
- 03:01 --> 03:03will randomly start developing seizures,
- 03:03 --> 03:06and as part of the work up they might
- 03:06 --> 03:09find the tumor and in some cases it
- 03:09 --> 03:11might be a very slow growing tumor,
- 03:11 --> 03:14in which case they might watch it for awhile
- 03:14 --> 03:17and they may not do anything with it,
- 03:17 --> 03:19because it might discover that it's been there
- 03:19 --> 03:21for the patients whole life for
- 03:21 --> 03:22most of their life,
- 03:22 --> 03:24and sometimes the resection or the
- 03:24 --> 03:26taking of the tumor might actually
- 03:26 --> 03:30put them at risk, so the slow growing to
- 03:30 --> 03:33more or less stable tumor like that,
- 03:34 --> 03:36it's much more of a thoughtful process
- 03:36 --> 03:39and I would evaluate them and then we would
- 03:39 --> 03:41test to see OK,
- 03:41 --> 03:44what are there risks in this case?
- 03:44 --> 03:46And so in that kind of tumor it's
- 03:46 --> 03:48I'm sure it's scary for that patient.
- 03:48 --> 03:51Have a tumor, but I think in those cases
- 03:51 --> 03:53that doctors are pretty clear of, well,
- 03:53 --> 03:55this might have been their whole life.
- 03:55 --> 03:57We don't know if it's growing,
- 03:57 --> 04:00we can kind of look at this and take
- 04:00 --> 04:03our time and figure out the next step.
- 04:03 --> 04:06So in that kind of situation I don't.
- 04:06 --> 04:07I mean, I'm not.
- 04:07 --> 04:09I've not had that happen to me,
- 04:09 --> 04:12but I don't imagine it sounds quite as
- 04:12 --> 04:15urgent as in cases where there is a
- 04:15 --> 04:17tumor that appears to have grown abruptly,
- 04:17 --> 04:20and that can be quite scary for the patients,
- 04:20 --> 04:23and so in those cases there's not
- 04:23 --> 04:26the time for me to kind of do a
- 04:26 --> 04:28presurgical work up and help them
- 04:28 --> 04:30figure out the next step.
- 04:30 --> 04:32In those cases where the tumors fast moving,
- 04:32 --> 04:35I'm sure it's much scarier for people.
- 04:35 --> 04:38Because it's so fast and many times I
- 04:38 --> 04:41cannot help at that point it's you know.
- 04:41 --> 04:42Like for example, this,
- 04:42 --> 04:45the surgeon might have to go in
- 04:45 --> 04:46and operate right away,
- 04:46 --> 04:49and so there's not even any time for the
- 04:49 --> 04:52patient to process what's about to happen,
- 04:52 --> 04:54let alone have them see me to
- 04:54 --> 04:56predict what's going to happen.
- 04:56 --> 04:59So in those cases, it's much more of a.
- 04:59 --> 05:00I'm following up,
- 05:00 --> 05:03and I'm seeing how they're doing afterwards,
- 05:03 --> 05:05but as you can imagine.
- 05:05 --> 05:07If it's a fast moving tumor,
- 05:07 --> 05:09the patient just wants to know
- 05:09 --> 05:11that they're going to live there.
- 05:11 --> 05:12Not worried about what I do.
- 05:12 --> 05:15In most cases, they just want to be OK,
- 05:15 --> 05:17'cause you know the brain tumor.
- 05:17 --> 05:20It's gotta be a scary thing to hear a doctor,
- 05:20 --> 05:21say to you.
- 05:21 --> 05:23You know, I can't imagine how,
- 05:23 --> 05:24how fearful that is.
- 05:24 --> 05:25But like I said,
- 05:25 --> 05:26there's different types and
- 05:26 --> 05:27more slow growing ones.
- 05:27 --> 05:29I'm sure the doctors can describe
- 05:29 --> 05:31those in a com away,
- 05:31 --> 05:32then when it's OK,
- 05:32 --> 05:34it's a tumor we have to
- 05:34 --> 05:36go and operate tomorrow. I can't
- 05:36 --> 05:37imagine how scary that would sound.
- 05:38 --> 05:41Yeah, and I would imagine that you know,
- 05:41 --> 05:43there's certainly a balance between
- 05:43 --> 05:46the symptoms that the brain tumor
- 05:46 --> 05:49is causing by being in your brain.
- 05:49 --> 05:52So for example, the seizures that you have
- 05:52 --> 05:55that maybe there on a daily or weekly
- 05:55 --> 05:57basis versus the potential disabilities
- 05:57 --> 06:00that you may have with resection.
- 06:00 --> 06:03How do you kind of balance that in
- 06:03 --> 06:06patients who might be thinking about,
- 06:06 --> 06:09you know, do I undergo a treatment,
- 06:09 --> 06:12whether it's surgery or radiation?
- 06:12 --> 06:15Versus do I live with this tumor if if
- 06:15 --> 06:17they're kind of facing that dichotomy,
- 06:17 --> 06:20how do you kind of counsel them?
- 06:20 --> 06:21So if
- 06:21 --> 06:24it's if it's a creditor that you describe,
- 06:24 --> 06:27which is usually the type that's not.
- 06:27 --> 06:28That did not going to die
- 06:28 --> 06:30immediately if it's not taken out.
- 06:30 --> 06:31There are of course case
- 06:31 --> 06:33where there's whether it so,
- 06:33 --> 06:35like if you don't take this out,
- 06:35 --> 06:37that's going to be it. You know,
- 06:37 --> 06:38I'm sure that those are the squirrels,
- 06:39 --> 06:41but the kind that you were talking about
- 06:41 --> 06:43are the ones that we actually have time to.
- 06:43 --> 06:45Maybe evaluate them before surgery and the
- 06:45 --> 06:47way that the test student works is well,
- 06:47 --> 06:49so will test different things.
- 06:49 --> 06:49Like I said,
- 06:49 --> 06:51the language in different kinds of memory,
- 06:51 --> 06:53and if it turns out that that part
- 06:53 --> 06:55of the brain with the tumors in
- 06:55 --> 06:57is not working properly anyways.
- 06:57 --> 06:59Like let's say the tumors in the
- 06:59 --> 07:01part of the brain that's important
- 07:01 --> 07:03for verbal memory and verbal memory
- 07:03 --> 07:06is terribly impaired at that point.
- 07:06 --> 07:08But that point we could say to them,
- 07:08 --> 07:10while you know there's very little
- 07:10 --> 07:11risk because you're already having
- 07:11 --> 07:12a lot of problems here,
- 07:12 --> 07:14and it's unlikely to get much worse,
- 07:14 --> 07:17and it might actually get better.
- 07:17 --> 07:18In that conversation,
- 07:18 --> 07:20the patient can take oh OK,
- 07:20 --> 07:20well,
- 07:20 --> 07:23so this is just causing problems and if he
- 07:23 --> 07:27takes it out of something to get much worse.
- 07:27 --> 07:27In other cases,
- 07:27 --> 07:28if the paint,
- 07:28 --> 07:30let's say a patient,
- 07:30 --> 07:31is very high functioning and
- 07:31 --> 07:33they have no problems and their
- 07:33 --> 07:35memories all their memory is great
- 07:35 --> 07:38and the tumors in a spot that if
- 07:38 --> 07:40they take it out it might impact
- 07:40 --> 07:41some important cognitive function.
- 07:41 --> 07:42You know,
- 07:42 --> 07:43let's say the persons a physician
- 07:43 --> 07:46or a physicist or chemist or an
- 07:46 --> 07:48engineer or or just anybody who's
- 07:48 --> 07:50brain is doing just fine is now told
- 07:50 --> 07:53that we the doctor may want to cut
- 07:53 --> 07:56out or take out part of their brain.
- 07:56 --> 07:57Naturally,
- 07:57 --> 07:59if there's if there's no pre existing
- 07:59 --> 08:01impairment from the tumor itself,
- 08:01 --> 08:03then you've gotta start asking.
- 08:03 --> 08:04Is this worth it?
- 08:04 --> 08:06And I think that in many cases
- 08:06 --> 08:09that depends on what's going on
- 08:09 --> 08:10with the neurosurgeon.
- 08:10 --> 08:11By say,
- 08:11 --> 08:13let's wait and watch and see
- 08:13 --> 08:15if it even grows.
- 08:15 --> 08:16There might be other alternatives.
- 08:16 --> 08:17For example,
- 08:17 --> 08:19maybe they'll try chemotherapy
- 08:19 --> 08:21or focused radiation therapy.
- 08:21 --> 08:22You know,
- 08:22 --> 08:24that's where it really gets in
- 08:24 --> 08:26the thick of what we want to do,
- 08:26 --> 08:28but I think that's really the next,
- 08:28 --> 08:28you know,
- 08:28 --> 08:29there's excellent conditions
- 08:29 --> 08:31in various places in it.
- 08:31 --> 08:31Yeah,
- 08:31 --> 08:34we have some very good ones that are very
- 08:34 --> 08:36good at detecting what can be taken out,
- 08:36 --> 08:38so they might take out part
- 08:38 --> 08:40of it but leave in part,
- 08:40 --> 08:41which sounds scary.
- 08:41 --> 08:42But it might be that if
- 08:42 --> 08:44they leave in that part,
- 08:44 --> 08:46there's a low risk for recurrence.
- 08:46 --> 08:48So there's many factors taken into account.
- 08:48 --> 08:49And believe me,
- 08:49 --> 08:50when the neurosurgeon has that
- 08:50 --> 08:51meeting with the patients.
- 08:51 --> 08:54They have looked at all different
- 08:54 --> 08:56options and I have to say
- 08:56 --> 08:58that the ones that I work with
- 08:58 --> 09:00their very thoughtful and very
- 09:00 --> 09:02much do not just say OK,
- 09:02 --> 09:03let's take it out.
- 09:03 --> 09:05Unless of course it's vital
- 09:05 --> 09:07for their life, you know.
- 09:07 --> 09:09So it does depend the type.
- 09:09 --> 09:11But Yes, there's many ways
- 09:11 --> 09:13that we could be careful to
- 09:13 --> 09:14reduce the risk after surgery.
- 09:14 --> 09:17So how exactly does that happen?
- 09:17 --> 09:19I mean, when we think about,
- 09:19 --> 09:20you know the neurosurgeon
- 09:20 --> 09:22going in there to take out.
- 09:22 --> 09:25Part of the brain where the tumor is.
- 09:25 --> 09:28But you know making sure that they
- 09:28 --> 09:31don't damage other parts of the brain,
- 09:31 --> 09:34that the tumor might be next to that.
- 09:34 --> 09:37If they they do take out or or damage
- 09:37 --> 09:40that area that the patient could be
- 09:40 --> 09:43left with severe deformities in terms
- 09:43 --> 09:46of you know their memory or their
- 09:46 --> 09:50cognition or their language skills.
- 09:50 --> 09:52Can the surgeons actually see which areas
- 09:52 --> 09:56which or do they need fancy image Ng?
- 09:56 --> 10:00Or is there a way that that's done with?
- 10:00 --> 10:02You know, while patients are awake,
- 10:02 --> 10:04I know that we've all seen kind
- 10:04 --> 10:06of shows on people taking care
- 10:06 --> 10:08of seizures with patients awake.
- 10:08 --> 10:10How does that happen for patients
- 10:10 --> 10:11with cancer?
- 10:11 --> 10:12So this is
- 10:12 --> 10:14a great question, and there's a
- 10:14 --> 10:17lot of tools that are now used
- 10:17 --> 10:19before the surgeon even goes in.
- 10:19 --> 10:21They have all these kinds of data.
- 10:21 --> 10:22I have time.
- 10:22 --> 10:24They've done different kinds of Mris.
- 10:24 --> 10:27There's a kind of MRI called
- 10:27 --> 10:28diffusion tensor imaging,
- 10:28 --> 10:29which actually tracks the
- 10:29 --> 10:31pathways in the brain because.
- 10:31 --> 10:33What are the biggest risks with
- 10:33 --> 10:35surgery is if they if they hit a
- 10:35 --> 10:36pathway they might not hit this
- 10:36 --> 10:38Center for some kinds of ticket.
- 10:38 --> 10:40But if you hit the wrong path
- 10:40 --> 10:41way you know could cause
- 10:41 --> 10:42some pretty global problems.
- 10:42 --> 10:44So with all the image Ng
- 10:44 --> 10:45data that's available today,
- 10:45 --> 10:47there are many ways that before
- 10:47 --> 10:49they even go in they already have
- 10:49 --> 10:51an idea of what they're going to
- 10:51 --> 10:52say that I can't speak for them,
- 10:52 --> 10:54but in the in the T meetings that
- 10:54 --> 10:56have been part of pretty much they
- 10:56 --> 10:58have an eye discharge and has a very
- 10:58 --> 11:00good idea exactly what they're going
- 11:00 --> 11:03to take out before they ever go in.
- 11:03 --> 11:04Now, sometimes once they're in,
- 11:04 --> 11:06they'll find the tumors more extensive
- 11:06 --> 11:08or has something more to problem,
- 11:08 --> 11:09but they were.
- 11:09 --> 11:11They are very careful.
- 11:11 --> 11:14You know, and that's that's really the key.
- 11:14 --> 11:15Now the other pieces.
- 11:15 --> 11:17Sometimes there is awake intra
- 11:17 --> 11:20operative map and it's called and
- 11:20 --> 11:22that means the patients actually
- 11:22 --> 11:24kept awake and some like myself
- 11:24 --> 11:26or other providers or even the
- 11:26 --> 11:28surgeon will talk to the patient
- 11:28 --> 11:31while doing the surgery to kind of
- 11:31 --> 11:33predict what's going to happen.
- 11:33 --> 11:34And there might.
- 11:34 --> 11:36They might even use a little
- 11:36 --> 11:38stimulation to kind of determine OK,
- 11:38 --> 11:41if we you know the stimulate the
- 11:41 --> 11:44area around the tumor to find out.
- 11:44 --> 11:46If they stimulate certain parts,
- 11:46 --> 11:47is it stopped language?
- 11:47 --> 11:48This language continue,
- 11:48 --> 11:50so sometimes during the actual
- 11:50 --> 11:52procedure the patient will be awake
- 11:52 --> 11:54and areas are under tomorrow be
- 11:54 --> 11:56stimulated to find out what would impact.
- 11:56 --> 11:59The impact would be if that
- 11:59 --> 12:00part was taken out.
- 12:00 --> 12:02So it's really quite amazing what
- 12:02 --> 12:04what they do in the neurosurgery
- 12:04 --> 12:06suite during these cases.
- 12:06 --> 12:08And now there's all kinds of newer tools.
- 12:08 --> 12:10There's a laser ablation therapy
- 12:10 --> 12:13where they'll take a laser and it's
- 12:13 --> 12:15like a same day procedure where they.
- 12:15 --> 12:18The next day, their home.
- 12:18 --> 12:19Of course.
- 12:19 --> 12:20Is there radiation types,
- 12:20 --> 12:22but but there are a lot of
- 12:22 --> 12:24different ways now that the surgeon
- 12:24 --> 12:26has to really know exactly what
- 12:26 --> 12:28they're going to be further going,
- 12:28 --> 12:30and so we will work with them.
- 12:30 --> 12:31We will have them do what's
- 12:31 --> 12:33called a functional MRI,
- 12:33 --> 12:35which Maps were different language
- 12:35 --> 12:36and other cognitive functions
- 12:36 --> 12:38might be occurring will do our
- 12:38 --> 12:39testing to kind of find out.
- 12:39 --> 12:39OK,
- 12:39 --> 12:42that tumor is in this area that
- 12:42 --> 12:44braid it would affect this function.
- 12:44 --> 12:46But see how that functions working now.
- 12:46 --> 12:48Let's predict what's going
- 12:48 --> 12:49to happen afterwards,
- 12:49 --> 12:51so it's really by the time
- 12:51 --> 12:52they go into surgery.
- 12:52 --> 12:53Unless it's an emergency situation,
- 12:53 --> 12:55there is a lot of planning,
- 12:55 --> 12:58and they pretty much know.
- 12:58 --> 12:59With a fairly good,
- 12:59 --> 13:01certainly what's going to happen before
- 13:01 --> 13:02the surgery even occurs.
- 13:02 --> 13:03That way, the patient and their
- 13:03 --> 13:05family could be talked about.
- 13:05 --> 13:07OK, here's what to expect.
- 13:07 --> 13:08Now of course, every once awhile
- 13:08 --> 13:10there might be a surprise,
- 13:10 --> 13:12and that's always your risk.
- 13:12 --> 13:13But many times that we really
- 13:13 --> 13:15strive so they know what to expect
- 13:15 --> 13:17before it even happens.
- 13:17 --> 13:19Yeah, I mean, it really is cool how
- 13:19 --> 13:21far surgery and technology is come.
- 13:21 --> 13:23It's kind of. It's kind of weird to
- 13:23 --> 13:25think about having somebody take out
- 13:25 --> 13:27a brain tumor with you being awake.
- 13:27 --> 13:29But on the other hand, it really is
- 13:29 --> 13:31pretty cool that you know you can.
- 13:31 --> 13:33You can give the surgeon
- 13:33 --> 13:34real time feedback of,
- 13:34 --> 13:36you know if you go in that spot.
- 13:36 --> 13:38I'm going to stop talking,
- 13:38 --> 13:40and if you go in that spot.
- 13:40 --> 13:44I'm going to start shaking and and so on.
- 13:44 --> 13:47You mentioned things like Lazaran radiation.
- 13:47 --> 13:49Are those more or less toxic to
- 13:49 --> 13:52your brain in terms of causing side
- 13:52 --> 13:56effects in terms of a bleeding tumors?
- 13:56 --> 13:58I mean, are they better in
- 13:58 --> 14:00terms of reducing the cognitive
- 14:00 --> 14:03side effects of having your
- 14:03 --> 14:04cancer treated well?
- 14:04 --> 14:07I know more about laser ablation from
- 14:08 --> 14:10the epilepsy patients at that time.
- 14:10 --> 14:13Part of seeing and I know that in
- 14:13 --> 14:16the research, a good friend of mine,
- 14:16 --> 14:18there's a lot of these another institution,
- 14:18 --> 14:20and they've had a large data set
- 14:20 --> 14:22of patients and they find that
- 14:22 --> 14:24the laser ablation has very has at
- 14:24 --> 14:27least Kogda Side Effects afterwards,
- 14:27 --> 14:29and we've actually learned that the
- 14:29 --> 14:32laser ablation you could take out
- 14:32 --> 14:33parts that traditional surgery.
- 14:33 --> 14:36It would have damage to surrounding area,
- 14:36 --> 14:38but laser ablation might be able to
- 14:38 --> 14:41pinpoint a very precise location so
- 14:41 --> 14:44that actually has fewer cognitive risks.
- 14:44 --> 14:45And in terms of radiation,
- 14:45 --> 14:48you know there's more focused beam
- 14:48 --> 14:50radiation that they use now they
- 14:50 --> 14:52used to use whole brain radiation,
- 14:52 --> 14:55which was not good because that would
- 14:55 --> 14:58affect the whole brain as as a name implies,
- 14:58 --> 14:59it's a whole brain.
- 14:59 --> 15:02Radiation would impact the cognition
- 15:02 --> 15:03in a larger degree.
- 15:03 --> 15:05Whereas focused beam radiation
- 15:05 --> 15:06would affect that area.
- 15:06 --> 15:09Now the risk to radiation is that is
- 15:09 --> 15:12not just a time that's being used,
- 15:12 --> 15:14but there's also after effects,
- 15:14 --> 15:16so the radiation might continue
- 15:16 --> 15:18to affect the area of the brain.
- 15:18 --> 15:21So some of the cognition might actually
- 15:21 --> 15:23decline a little bit after the surgery,
- 15:23 --> 15:25after the radiation is even
- 15:25 --> 15:27over down the road,
- 15:27 --> 15:29you can have a little bit of
- 15:29 --> 15:31decline in that immediate area.
- 15:31 --> 15:32So yeah,
- 15:32 --> 15:32no sorry.
- 15:32 --> 15:34So this is. Really fascinating
- 15:34 --> 15:37in terms of how we can influence
- 15:37 --> 15:39our cognition while still
- 15:39 --> 15:42taking care of brain tumors.
- 15:42 --> 15:45We need to take a short break
- 15:45 --> 15:47for a medical minute,
- 15:47 --> 15:50but will learn more right after this
- 15:50 --> 15:53break with my guest. Doctor Franklin Brown.
- 15:53 --> 15:56Support for Yale cancer answers comes from
- 15:56 --> 15:58Astra Zeneca of biopharmaceutical business.
- 15:58 --> 16:01With a deep rooted heritage in oncology and
- 16:01 --> 16:05a commitment to developing cancer medicines
- 16:05 --> 16:07for patientslearnmore@astrazeneca-us.com.
- 16:07 --> 16:09This is a medical minute about
- 16:09 --> 16:11pancreatic cancer, which represents
- 16:11 --> 16:14about 3% of all cancers in the US,
- 16:14 --> 16:17Ann, about 7% of cancer deaths.
- 16:17 --> 16:19Clinical trials are currently being
- 16:19 --> 16:20offered at Federale designated
- 16:20 --> 16:22comprehensive cancer Centers for the
- 16:22 --> 16:24treatment of advanced stage and metastatic
- 16:24 --> 16:26pancreatic cancer using chemotherapy.
- 16:26 --> 16:28Another novel therapies,
- 16:28 --> 16:30Phil Fearon, ox or combination of
- 16:30 --> 16:31five different chemotherapies,
- 16:31 --> 16:34is the latest advance in the treatment
- 16:34 --> 16:36of metastatic pancreatic cancer.
- 16:36 --> 16:37And research continues.
- 16:37 --> 16:39It centers around the world
- 16:39 --> 16:41looking into targeted therapies,
- 16:41 --> 16:44and a recently discovered marker HENT one.
- 16:44 --> 16:47This is been a medical minute brought to you
- 16:47 --> 16:51as a public service by Yale Cancer Center.
- 16:51 --> 16:54More information is available at
- 16:54 --> 16:55yalecancercenter.org you're listening
- 16:55 --> 16:57to Connecticut public radio.
- 16:57 --> 16:57Welcome
- 16:57 --> 16:59back to Yale cancer answers.
- 16:59 --> 17:02This is doctor in East shag part
- 17:02 --> 17:04and I'm joined tonight by my guest
- 17:04 --> 17:06doctor Franklin Brown were talking
- 17:06 --> 17:08about neuropsychology and brain
- 17:08 --> 17:11cancer and right before the break.
- 17:11 --> 17:14Franklin we were talking a little bit
- 17:14 --> 17:16about surgery versus radiation which
- 17:16 --> 17:19can be focused or even lasers which can
- 17:19 --> 17:22be perhaps even more focused where you
- 17:22 --> 17:25know we can really address brain cancers
- 17:25 --> 17:27without affecting the entire brain.
- 17:27 --> 17:29Now the. The other modality,
- 17:29 --> 17:32of course that is sometimes used
- 17:32 --> 17:34is is chemotherapy and, you know,
- 17:34 --> 17:37chemotherapy can affect your brain to a
- 17:37 --> 17:40lot of people talk about chemo brain.
- 17:40 --> 17:43Can you talk a little bit about how
- 17:43 --> 17:46exactly does chemotherapy affect your brain?
- 17:46 --> 17:49I mean, it's certainly not a structural
- 17:49 --> 17:53thing of taking actual brain tissue out,
- 17:53 --> 17:55but it seems to still
- 17:55 --> 17:57affect people's cognition was sure,
- 17:57 --> 17:59and in fact, chemo.
- 17:59 --> 18:00Chemotherapy, while it's important,
- 18:00 --> 18:02can leave comments effects
- 18:02 --> 18:04regardless of the type of tumor.
- 18:04 --> 18:06Sowerby regards the type of cancer,
- 18:06 --> 18:08so we're talking about brain tumors,
- 18:08 --> 18:10but in any kind of cancer
- 18:10 --> 18:12that chemotherapy is used,
- 18:12 --> 18:14it can cross the blood brain barrier,
- 18:14 --> 18:17an effect the brain now.
- 18:17 --> 18:19The way this typically happens in the brain,
- 18:19 --> 18:21there's what's called the Gray matter,
- 18:21 --> 18:24which is where our actual thinking sells.
- 18:24 --> 18:27For like, a better term would be located.
- 18:27 --> 18:31But then this was called the white matter,
- 18:31 --> 18:34which connects to different parts of the
- 18:34 --> 18:36brain together and that white matter
- 18:36 --> 18:38is very important for functioning
- 18:38 --> 18:41but also for function efficiently.
- 18:41 --> 18:44So let's say that the chemotherapy because
- 18:44 --> 18:47it affects the person's general health.
- 18:47 --> 18:50This effects white matter.
- 18:50 --> 18:52More than Gray matter.
- 18:52 --> 18:52In fact,
- 18:52 --> 18:55it tested target white matter because white
- 18:55 --> 18:57matters affected by the body's health, so.
- 18:57 --> 19:00You have the white matter that gets
- 19:00 --> 19:03affected by chemotherapy and afterwards
- 19:03 --> 19:06patients have they feel foggy there.
- 19:06 --> 19:08Say they can't focus very well.
- 19:08 --> 19:10They're complaining memory problems,
- 19:10 --> 19:13and it really comes down to the brain
- 19:13 --> 19:15not communicating efficiently anymore.
- 19:15 --> 19:16And so it's.
- 19:16 --> 19:19There's different networks in the brain.
- 19:19 --> 19:21So let's say the actual.
- 19:21 --> 19:22Like I said,
- 19:22 --> 19:25the brain centers might be intact,
- 19:25 --> 19:27but the communication between
- 19:27 --> 19:29those centers are slowed down.
- 19:29 --> 19:30Therefore,
- 19:30 --> 19:31kits at a sink.
- 19:31 --> 19:33So imagine one way it imagine this
- 19:33 --> 19:35is like if you're very tired.
- 19:35 --> 19:38Let's say that you only got a few
- 19:38 --> 19:40hours sleep the night before and the
- 19:40 --> 19:43next day you're feeling kind of foggy.
- 19:43 --> 19:45You can't think as well.
- 19:45 --> 19:46You mind might wander,
- 19:46 --> 19:49you know all those things that you feel
- 19:49 --> 19:52when you're very tired and in a way,
- 19:52 --> 19:54this is kind of what chemotherapy
- 19:54 --> 19:56does the brain.
- 19:56 --> 19:58Because it makes it less efficient.
- 19:58 --> 20:00Your brain. It takes a lot more.
- 20:00 --> 20:01For to do things.
- 20:01 --> 20:03So this will result in the
- 20:03 --> 20:06person feeling tired, unfocused.
- 20:06 --> 20:08You know other factors that make
- 20:08 --> 20:10them less able to pay attention
- 20:10 --> 20:12to what's going on,
- 20:12 --> 20:14so cognitive efficiency is actually
- 20:14 --> 20:18is one of my areas of interest
- 20:18 --> 20:20is very vital for thinking.
- 20:20 --> 20:21Paid attention.
- 20:21 --> 20:24You know finding towards another
- 20:24 --> 20:26actions that are required
- 20:26 --> 20:28that chemotherapy affects so
- 20:28 --> 20:32you know, having thought about that right?
- 20:32 --> 20:34So especially when there is
- 20:34 --> 20:37some time to prepare, right?
- 20:37 --> 20:39So usually, regardless of whether
- 20:39 --> 20:42somebody is taking out a piece
- 20:42 --> 20:45of brain from brain tumor or
- 20:45 --> 20:47planning some focused radiation,
- 20:47 --> 20:50or whether you're going to be
- 20:50 --> 20:52getting some chemotherapy.
- 20:52 --> 20:54For brain cancer or any
- 20:54 --> 20:55other cancer for that matter,
- 20:55 --> 20:57oftentimes there's some preparatory
- 20:57 --> 20:58work that goes into that,
- 20:58 --> 21:00and we had talked before the break
- 21:00 --> 21:02about you know certainly in preparation
- 21:02 --> 21:04for brain surgery to remove tumors
- 21:04 --> 21:05that there's functional MRI's,
- 21:05 --> 21:07and so on and so forth.
- 21:07 --> 21:10So you have some time now I can
- 21:10 --> 21:12imagine that a lot of people who
- 21:12 --> 21:14might be listening to this show might
- 21:14 --> 21:16be asking themselves, you know,
- 21:16 --> 21:19is there something I can do?
- 21:19 --> 21:21In that period of time when I know
- 21:21 --> 21:24that my brain is going to be affected
- 21:24 --> 21:26by whatever treatment is to come,
- 21:26 --> 21:29is there something that I can do to help
- 21:29 --> 21:32myself preserve some of my cognition?
- 21:32 --> 21:34You know whether that is particularly a
- 21:34 --> 21:36particular diet that I should be eating,
- 21:36 --> 21:38or particular vitamins that
- 21:38 --> 21:39I should be taking,
- 21:39 --> 21:41or whether I should be doing
- 21:41 --> 21:43more crossword puzzles and trying
- 21:43 --> 21:45to keep my brain active?
- 21:45 --> 21:47Like what advice do you have,
- 21:47 --> 21:49or is there any advice?
- 21:49 --> 21:52For helping people to kind of
- 21:52 --> 21:54shore up their their brainpower,
- 21:54 --> 21:57their cognition to best withstand
- 21:57 --> 22:00the insult that is about to occur.
- 22:01 --> 22:03Well, one of the things that a lot of
- 22:03 --> 22:06people may not realize is that your
- 22:06 --> 22:08brain health things that make your
- 22:08 --> 22:10brain healthy are the same things
- 22:10 --> 22:12that make your heart healthy and in
- 22:12 --> 22:14fact was a big connection between
- 22:14 --> 22:16brain health and heart health.
- 22:16 --> 22:18In other words, if someones if
- 22:18 --> 22:20someone's cardiovascular system is is
- 22:20 --> 22:22at risk than their brain function,
- 22:22 --> 22:24it can be at risk,
- 22:24 --> 22:25which is a whole other topic,
- 22:26 --> 22:28but I think that one of the big things
- 22:28 --> 22:30is the healthier person is going
- 22:30 --> 22:32into a therapeutic situation like
- 22:32 --> 22:34chemotherapy or radiation or whatever.
- 22:34 --> 22:37The better the outcome generally,
- 22:37 --> 22:39so this means that if the person is
- 22:39 --> 22:42someone that exercises fairly regularly,
- 22:42 --> 22:45eats fairly healthy and you know
- 22:45 --> 22:47there's other things like that,
- 22:47 --> 22:50then they are going to be at
- 22:50 --> 22:53lower risk in general.
- 22:53 --> 22:55After surgery for cognitive problems
- 22:55 --> 22:58that people that let's say or less
- 22:58 --> 23:00healthy that might have some medical
- 23:00 --> 23:02risk factors like high blood pressure,
- 23:02 --> 23:03high cholesterol,
- 23:03 --> 23:05maybe they don't exercise really.
- 23:05 --> 23:07Maybe they are overweight,
- 23:07 --> 23:10you know there's all these things that
- 23:10 --> 23:12the more of these problems that occur,
- 23:12 --> 23:15the higher risk your brain is for.
- 23:15 --> 23:17For not being as healthy both
- 23:17 --> 23:20before and then after a surgery.
- 23:20 --> 23:22Sleep is also very important,
- 23:22 --> 23:24so following good sleep hygiene
- 23:24 --> 23:25recommendations is important,
- 23:25 --> 23:28but if you have someone that doesn't
- 23:28 --> 23:30exercise from that doesn't sleep well,
- 23:30 --> 23:32maybe they work long hours.
- 23:32 --> 23:34You know these are all things that
- 23:34 --> 23:36that when you think of Health,
- 23:36 --> 23:38the more or less healthy person
- 23:38 --> 23:41is a more cognitive risks they
- 23:41 --> 23:42have and vice versa.
- 23:42 --> 23:44So definitely that affects
- 23:44 --> 23:47the other thing is also mood.
- 23:47 --> 23:49You know it could be very upsetting to
- 23:49 --> 23:52find out someone has cancer and that
- 23:52 --> 23:54can affect the person pretty rapidly.
- 23:54 --> 23:56So the other thing is how do
- 23:56 --> 23:58you keep your mood up now?
- 23:58 --> 24:00Of course there are answer,
- 24:00 --> 24:02depresses and things like that.
- 24:02 --> 24:04But I'm actually a big a big believer
- 24:04 --> 24:07in therapy and so I really think that
- 24:07 --> 24:10when someone gets diagnosed with cancer.
- 24:10 --> 24:10To me,
- 24:10 --> 24:12I mean maybe I'm biased,
- 24:12 --> 24:14but from my perspective think if they
- 24:14 --> 24:17could all have access to accounts are.
- 24:17 --> 24:19Added time and after the diagnosis to
- 24:19 --> 24:22help them reframe their way of thinking,
- 24:22 --> 24:23deal with their anxiety.
- 24:23 --> 24:25So they can decrease depression
- 24:25 --> 24:28and anxiety going into it.
- 24:28 --> 24:30They're going to be better off
- 24:30 --> 24:32shape when they come out of it.
- 24:32 --> 24:35So things like that are very important.
- 24:35 --> 24:38An I mentioned sleep briefly.
- 24:38 --> 24:40There is growing evidence that sleep
- 24:40 --> 24:43definitely affects the brain functioning.
- 24:43 --> 24:44Whether it's long term,
- 24:44 --> 24:45for example sleep,
- 24:45 --> 24:47chronic seat problems are associated with
- 24:47 --> 24:50a higher risk of Alzheimer's disease,
- 24:50 --> 24:52or whether it's short term.
- 24:52 --> 24:54Adjust the immediate effects of fatigue.
- 24:54 --> 24:54Obviously,
- 24:54 --> 24:56if someone's having chronic sleep problems,
- 24:57 --> 24:59they're going to be more fatigue
- 24:59 --> 25:01and had more difficulty focusing.
- 25:01 --> 25:03Those things are also really important
- 25:03 --> 25:05for recovery from any kind of whether
- 25:05 --> 25:07it's a direct brain resection,
- 25:07 --> 25:08radiation therapy,
- 25:08 --> 25:09or chemotherapy.
- 25:09 --> 25:12So those are the things that.
- 25:12 --> 25:13I think in the idea world,
- 25:13 --> 25:15if we could really help the
- 25:15 --> 25:17patients go into it healthy.
- 25:17 --> 25:20Focus on it in a healthy way.
- 25:20 --> 25:22Help help deal with feelings
- 25:22 --> 25:23of depression, anxiety.
- 25:23 --> 25:25They're going to come out
- 25:25 --> 25:27with it out of it much better.
- 25:27 --> 25:30So it definitely there are ways
- 25:30 --> 25:32that that you can improve a
- 25:32 --> 25:34person's outcome in their risks.
- 25:34 --> 25:36Yeah, you know, all of that makes
- 25:36 --> 25:39me think about stress as well.
- 25:39 --> 25:41And you know, the the kind of
- 25:41 --> 25:43correlations between stress and
- 25:43 --> 25:45inflammation and an cancer in general,
- 25:45 --> 25:48but it sounds like kind of
- 25:48 --> 25:49regulating your stress might
- 25:49 --> 25:51might be helpful in terms of.
- 25:51 --> 25:53Preserving your brain function
- 25:53 --> 25:56as well are are there data on
- 25:56 --> 25:58that and an any particular things
- 25:58 --> 26:00in terms of stress reduction,
- 26:00 --> 26:02whether it be meditation or you
- 26:02 --> 26:03certainly mentioned exercise.
- 26:04 --> 26:06Right, so absolutely stresses
- 26:06 --> 26:10deftly can be toxic to the brain.
- 26:10 --> 26:12That there's been in decades past.
- 26:12 --> 26:14There's a lot of research and stress
- 26:14 --> 26:17and anxiety in the brain and there it
- 26:17 --> 26:19actually stress levels can actually impact
- 26:19 --> 26:22the size and volume of a memory center
- 26:22 --> 26:24of the brain called the hippocampus.
- 26:24 --> 26:26There were states that they did in the
- 26:26 --> 26:2880s and 90s where they actually found
- 26:28 --> 26:31that people with higher levels of stress
- 26:31 --> 26:33will have smaller memory centers like that.
- 26:33 --> 26:35The campus and then after they
- 26:35 --> 26:37get treated for that stress,
- 26:37 --> 26:38the MRI actually shows some
- 26:38 --> 26:39rebounding of the size,
- 26:39 --> 26:42which is unbelievable but is amazing so.
- 26:42 --> 26:44Absolutely, you know, stress is such
- 26:44 --> 26:47an important thing to help cope with,
- 26:47 --> 26:50and I think that you know
- 26:50 --> 26:51when someone's here.
- 26:51 --> 26:53We get diagnosed with cancer.
- 26:53 --> 26:57There focused might just be an OK I want to.
- 26:57 --> 26:59I want to survive.
- 26:59 --> 27:01I want to be healthy,
- 27:01 --> 27:04but the way they survive in the
- 27:04 --> 27:07way they feel is absolutely vital.
- 27:07 --> 27:09So things like obviously just
- 27:09 --> 27:11you know talking therapist really
- 27:11 --> 27:13helpful thing mindfulness meditation.
- 27:13 --> 27:15Some people also do well with
- 27:15 --> 27:16what's called cognitive imagery,
- 27:16 --> 27:19where they are asked to imagine the
- 27:19 --> 27:22situation so they calm down and imagine
- 27:22 --> 27:24it working out at a certain way.
- 27:24 --> 27:26There's been studies in various areas
- 27:26 --> 27:28that find that guided imagery where
- 27:28 --> 27:31person imagines their outcome seems to
- 27:31 --> 27:33produce a sense of better self control
- 27:33 --> 27:35and had better locus of control,
- 27:35 --> 27:37which seems to help their outcomes.
- 27:37 --> 27:38You know,
- 27:38 --> 27:40so definitely the level of stress
- 27:40 --> 27:41is very important,
- 27:41 --> 27:43and the more we can treat that
- 27:43 --> 27:45and reduce the level of stress
- 27:45 --> 27:47before and after surgery,
- 27:47 --> 27:48the better the outcome.
- 27:48 --> 27:52And of course it better the quality of life.
- 27:52 --> 27:52You know.
- 27:52 --> 27:54If someone is feeling depressed and
- 27:54 --> 27:57they feel like they're hopeless.
- 27:57 --> 27:58And they feel like there's no
- 27:58 --> 28:00way out and they look at their
- 28:00 --> 28:02health and they just can't imagine
- 28:02 --> 28:04that it's going to workout.
- 28:04 --> 28:06They're not going to do well,
- 28:06 --> 28:07no matter what an versus someone
- 28:07 --> 28:09that has an optimistic viewpoint.
- 28:09 --> 28:12It says, OK, well, this is not a big deal.
- 28:12 --> 28:14The doctor said that this could work,
- 28:14 --> 28:16and I know it's going to work fine,
- 28:16 --> 28:18and they imagine it's going to work.
- 28:18 --> 28:19It's really remarkable.
- 28:19 --> 28:20The difference in outcomes
- 28:20 --> 28:23then, and that's where I think
- 28:23 --> 28:24that that talk therapy can
- 28:24 --> 28:26really help. But you mentioned.
- 28:26 --> 28:30Yes, so there's a kind of typical
- 28:30 --> 28:31cognitive behavioral therapy. An.
- 28:31 --> 28:33That's when people that with the
- 28:33 --> 28:35provider works would help the
- 28:35 --> 28:37person to reframe their thinking.
- 28:37 --> 28:39So maybe they could take
- 28:39 --> 28:40something and instead thinking
- 28:40 --> 28:42negative negatively about it,
- 28:42 --> 28:44think more positively and effects
- 28:44 --> 28:46to give you an example of a
- 28:46 --> 28:48different area in multiple sclerosis
- 28:48 --> 28:50which also affects white matter.
- 28:50 --> 28:51And I mention chemotherapy
- 28:51 --> 28:52effects white matter.
- 28:52 --> 28:54There's actually evidence that people
- 28:54 --> 28:57that have multiple sclerosis who go
- 28:57 --> 28:58through constant behavioral therapy
- 28:58 --> 29:01have fewer relapses in there and
- 29:01 --> 29:02their white matter looks better.
- 29:02 --> 29:05So there is definitely evidence
- 29:05 --> 29:07that talk therapy, guided imagery,
- 29:07 --> 29:09relaxation, meditation, sleeping well,
- 29:09 --> 29:11eating well and healthy exercise
- 29:11 --> 29:13are very helpful.
- 29:13 --> 29:16And cancer is actually some empirical data.
- 29:16 --> 29:18That exercise helps recovery cognitive
- 29:18 --> 29:21remediation which is like like
- 29:21 --> 29:23things like speech therapy or or
- 29:23 --> 29:25focused therapy to help someone's
- 29:25 --> 29:28memory or compensation strategies.
- 29:28 --> 29:30All these things have been found
- 29:30 --> 29:33empirically to help the outcomes.
- 29:33 --> 29:35Of people that go through chemotherapy,
- 29:35 --> 29:37but definitely stress, I think,
- 29:37 --> 29:39is definitely underlying factor
- 29:39 --> 29:41in all these interventions.
- 29:41 --> 29:43Doctor Franklin Brown is an assistant
- 29:43 --> 29:46professor of neurology and chief
- 29:46 --> 29:48of the division of neuropsychology
- 29:48 --> 29:50at the Yale School of Medicine.
