  • 00:00 --> 00:02Support for Yale Cancer Answers
  • 00:02 --> 00:05comes from AstraZeneca, working
  • 00:05 --> 00:07side by side with leading
  • 00:07 --> 00:09scientists to better understand how
  • 00:10 --> 00:15complex data can be converted
  • 00:15 --> 00:16into innovative treatments. More
  • 00:16 --> 00:17information at astrazeneca-us.com.
  • 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.
