  • 00:13 --> 00:15Welcome to Yale Cancer Answers with
  • 00:15 --> 00:18your host doctor Anees Chagpar.
  • 00:18 --> 00:19Yale Cancer Answers features the
  • 00:19 --> 00:22latest information on cancer care by
  • 00:22 --> 00:23welcoming oncologists and specialists
  • 00:23 --> 00:26who are on the forefront of the
  • 00:26 --> 00:28battle to fight cancer. This week,
  • 00:28 --> 00:29it's a conversation about understanding
  • 00:29 --> 00:32medical research with Doctor Perry Wilson.
  • 00:32 --> 00:34Doctor Wilson is the course director of
  • 00:34 --> 00:36Interpretation of the medical literature
  • 00:36 --> 00:38at the Yale School of Medicine,
  • 00:38 --> 00:40where Doctor Chagpar is a
  • 00:40 --> 00:41professor of surgical oncology.
  • 00:42 --> 00:45Perry, maybe we can start off by you
  • 00:45 --> 00:48telling us a little bit about yourself
  • 00:48 --> 00:50and what it is that you do.
  • 00:50 --> 00:52I'm a physician,
  • 00:52 --> 00:54and I specialize in internal
  • 00:54 --> 00:55medicine and nephrology,
  • 00:55 --> 00:56which is kidney diseases.
  • 00:56 --> 00:59But most of my time is spent
  • 00:59 --> 01:00doing clinical research.
  • 01:00 --> 01:02So my lab does clinical trials.
  • 01:02 --> 01:05We use a lot of what people
  • 01:05 --> 01:07might call big data approaches.
  • 01:07 --> 01:09Getting data and analysis into
  • 01:09 --> 01:10the electronic health record,
  • 01:10 --> 01:14but I think one of my real passions has been
  • 01:14 --> 01:15trying to explain medical
  • 01:15 --> 01:17research to everyone.
  • 01:17 --> 01:19It's something that I love to do.
  • 01:19 --> 01:21I love medical research.
  • 01:21 --> 01:23I think it's
  • 01:23 --> 01:24transformed humanity over the
  • 01:24 --> 01:27past century and I want to share
  • 01:27 --> 01:28that enthusiasm with people.
  • 01:28 --> 01:30And so I've been, on my
  • 01:30 --> 01:33off hours, writing columns
  • 01:33 --> 01:35about new medical studies trying
  • 01:35 --> 01:38to get people as excited as I am
  • 01:38 --> 01:40about the medical research process.
  • 01:41 --> 01:43And that's such a great
  • 01:43 --> 01:45thing to kick off with because,
  • 01:45 --> 01:47especially this year,
  • 01:47 --> 01:50there's been a lot of
  • 01:50 --> 01:50misinformation,
  • 01:50 --> 01:52a lot of ambiguity,
  • 01:52 --> 01:55a lot of trepidation on the part of
  • 01:55 --> 01:57the general public about medical research,
  • 01:57 --> 02:00so maybe you can start off by talking
  • 02:00 --> 02:04to us a little bit about how that
  • 02:04 --> 02:05misinformation gets propagated
  • 02:05 --> 02:08and what we can do about it.
  • 02:08 --> 02:10Sure, Covid has really turned
  • 02:10 --> 02:13up the level of medical misinformation.
  • 02:13 --> 02:15It's always been out there.
  • 02:15 --> 02:18It's even before the Internet there were
  • 02:18 --> 02:20people coming through
  • 02:20 --> 02:22with their patent medicines and
  • 02:22 --> 02:25tonics and trying to force
  • 02:25 --> 02:27something in a vial on an unsuspecting
  • 02:27 --> 02:30population that will always be there.
  • 02:30 --> 02:32There will always be people trying to
  • 02:32 --> 02:35make a buck from fake information,
  • 02:35 --> 02:37but as the Internet exploded and access
  • 02:37 --> 02:40to information became more available
  • 02:40 --> 02:42as social media exploded and the sharing
  • 02:42 --> 02:43of information became
  • 02:43 --> 02:45exponentially easier and then now with covid,
  • 02:45 --> 02:48it was really this perfect storm of medical
  • 02:48 --> 02:50information that we were
  • 02:50 --> 02:51all hit with.
  • 02:51 --> 02:53It was the first time I can remember
  • 02:53 --> 02:54where literally everyone was
  • 02:54 --> 02:56searching for the same thing on line
  • 02:56 --> 02:58when it comes to medical studies.
  • 02:58 --> 02:59So before covid,
  • 02:59 --> 03:01you had people that were
  • 03:01 --> 03:03looking for the latest diet that
  • 03:03 --> 03:05would help them lose a few pounds.
  • 03:05 --> 03:06And then
  • 03:06 --> 03:08of course you had people who might
  • 03:08 --> 03:10have had a new diagnosis like a
  • 03:10 --> 03:12new cancer diagnosis for example,
  • 03:12 --> 03:13and they're searching that.
  • 03:13 --> 03:14And there's misinformation in
  • 03:14 --> 03:15all those spaces,
  • 03:15 --> 03:18but all of a sudden 2020 comes and every
  • 03:18 --> 03:20single person is searching for any
  • 03:20 --> 03:22information they can find about covid.
  • 03:22 --> 03:24And in that environment you are
  • 03:24 --> 03:27going to get a lot of misinformation
  • 03:27 --> 03:29out there. And that's exactly what happened.
  • 03:29 --> 03:31But you know, Perry,
  • 03:31 --> 03:33it's really interesting because for
  • 03:33 --> 03:35many people they think the Internet
  • 03:35 --> 03:37was really the boon of information
  • 03:37 --> 03:39sharing and a great way for people
  • 03:39 --> 03:41to get high quality information and
  • 03:41 --> 03:43disseminate it across a large population.
  • 03:43 --> 03:46So I think one of the key issues is how do
  • 03:46 --> 03:49people distinguish from good information
  • 03:49 --> 03:51factual information versus misinformation.
  • 03:51 --> 03:53Both of them seem to be
  • 03:53 --> 03:55apparent on the Internet,
  • 03:55 --> 03:58but sometimes it's hard to tell them apart.
  • 03:58 --> 03:59Yeah, absolutely.
  • 03:59 --> 04:00And this is
  • 04:00 --> 04:02one of the double edged
  • 04:02 --> 04:04swords of our information age.
  • 04:04 --> 04:07So one thing I always remind
  • 04:07 --> 04:10people is that there is such a thing
  • 04:10 --> 04:13as a bad medical study. There is
  • 04:13 --> 04:15good data and bad data.
  • 04:15 --> 04:18There are good studies and bad studies,
  • 04:18 --> 04:20and when access to that information
  • 04:20 --> 04:22is so readily available so unfiltered
  • 04:22 --> 04:24or sometimes just filtered through
  • 04:24 --> 04:27the sort of biases of whoever's on
  • 04:27 --> 04:29your social media feed, it
  • 04:29 --> 04:31has become really easy to
  • 04:31 --> 04:32find information that confirms
  • 04:32 --> 04:34your previously held beliefs,
  • 04:34 --> 04:37and if there is one thing I sort
  • 04:37 --> 04:39of caution people against when they
  • 04:39 --> 04:42go looking for information is,
  • 04:42 --> 04:43do it with an open mind.
  • 04:43 --> 04:46Don't try to find things that confirm
  • 04:46 --> 04:48what you already believe to be true,
  • 04:48 --> 04:49because maybe that worked back in
  • 04:49 --> 04:51the day when you went into the
  • 04:51 --> 04:53encyclopedia and everything was
  • 04:53 --> 04:55sort of nicely laid out and had
  • 04:55 --> 04:57been vetted by an editorial board
  • 04:57 --> 04:58and things like that.
  • 04:58 --> 05:01But the problem with social media is
  • 05:01 --> 05:03similar beliefs cluster together. The
  • 05:03 --> 05:05social media algorithms on Twitter
  • 05:05 --> 05:07and Facebook and Instagram and all of
  • 05:07 --> 05:10the social media companies work the same way.
  • 05:10 --> 05:12They are designed to maximize engagement,
  • 05:12 --> 05:14which is eyeballs on the screen,
  • 05:14 --> 05:15clicks, likes,
  • 05:15 --> 05:16retweets etc.
  • 05:16 --> 05:17In that environment,
  • 05:17 --> 05:19things that are nuanced that are
  • 05:19 --> 05:22subtle that don't sort of confirm
  • 05:22 --> 05:24what people want to be true don't
  • 05:24 --> 05:26get a lot of engagement,
  • 05:26 --> 05:28and those things that are more
  • 05:28 --> 05:30exciting and dramatic,
  • 05:30 --> 05:32we've got a cure for covid in
  • 05:32 --> 05:34our medicine chest right now.
  • 05:34 --> 05:37It gets a ton of engagement and one
  • 05:37 --> 05:39of the things that we used to be
  • 05:39 --> 05:41able to do as humans was trust
  • 05:41 --> 05:44what we perceive as the majority opinion
  • 05:44 --> 05:46when a lot of people share an opinion,
  • 05:46 --> 05:49we would go around in our social lives
  • 05:49 --> 05:51and say, oh that's probably true.
  • 05:51 --> 05:53Most people sort of think this,
  • 05:53 --> 05:55and I've heard this from a number
  • 05:55 --> 05:57of people in social media,
  • 05:57 --> 05:59now it's possible to go down a rabbit
  • 05:59 --> 06:01hole of misinformation where every
  • 06:01 --> 06:04voice you see every link you click is
  • 06:04 --> 06:05reinforcing the false information.
  • 06:05 --> 06:08And what you then get is this
  • 06:08 --> 06:09erroneous perception that there's
  • 06:09 --> 06:12this wealth of data out there
  • 06:12 --> 06:13that's supporting your belief,
  • 06:13 --> 06:16when in fact it's all this
  • 06:16 --> 06:18self perpetuating engagement,
  • 06:18 --> 06:21and you've got to be able to
  • 06:21 --> 06:22get out of there.
  • 06:22 --> 06:25The easiest way is right off the bat,
  • 06:25 --> 06:27be honest with yourself.
  • 06:27 --> 06:30Ask yourself what you want to be true,
  • 06:30 --> 06:33and recognize that if you find data
  • 06:33 --> 06:36that supports what you want to be true,
  • 06:36 --> 06:38you even have to be extra
  • 06:38 --> 06:40skeptical about that type of
  • 06:40 --> 06:43data.
  • 06:43 --> 06:46I just finished reading Adam Grant's book,
  • 06:46 --> 06:48Think Again, which for if anybody is
  • 06:48 --> 06:52a big fan of Adam Grant or enjoys
  • 06:52 --> 06:54reading organizational psychologists,
  • 06:54 --> 06:55I highly recommend it.
  • 06:55 --> 06:58But it's exactly to your point about
  • 06:58 --> 07:01rethinking your biases.
  • 07:01 --> 07:03But you know Perry,
  • 07:03 --> 07:04it's really difficult, right?
  • 07:04 --> 07:07Because if you are looking for something,
  • 07:07 --> 07:09something appears to be true,
  • 07:09 --> 07:12it fits with your gut,
  • 07:12 --> 07:14you're more likely to
  • 07:14 --> 07:15think that that's right,
  • 07:15 --> 07:17so are there any objective ways
  • 07:17 --> 07:18for example,
  • 07:18 --> 07:21if patients or the people
  • 07:21 --> 07:24who are listening to our show today,
  • 07:24 --> 07:25they may have just been
  • 07:25 --> 07:26diagnosed with cancer,
  • 07:26 --> 07:29or they may be looking for other
  • 07:29 --> 07:31medical information and it's
  • 07:31 --> 07:33so easy to go to the Internet.
  • 07:33 --> 07:35Information at our fingertips.
  • 07:35 --> 07:38Are there any ways that you can
  • 07:38 --> 07:39really distinguish, intangible ways,
  • 07:39 --> 07:43Igood information versus garbage?
  • 07:45 --> 07:47There certainly are and it
  • 07:47 --> 07:49does take a
  • 07:49 --> 07:52little bit of work and
  • 07:52 --> 07:54it's the hardest thing in the
  • 07:54 --> 07:56world to disregard information
  • 07:56 --> 07:58that feels right to you.
  • 07:58 --> 08:01That speaks to you in that way because
  • 08:01 --> 08:04that is a very human thing that we all do.
  • 08:04 --> 08:07But I can
  • 08:07 --> 08:09give you a couple of tips.
  • 08:09 --> 08:11So number one,
  • 08:11 --> 08:12is that biologic plausibility
  • 08:12 --> 08:14is only the start of
  • 08:14 --> 08:16medical research, not the end,
  • 08:16 --> 08:18and what I mean by biologic
  • 08:18 --> 08:19plausibility is when something is
  • 08:19 --> 08:21stated that makes sense biologically.
  • 08:23 --> 08:25To give you an example,
  • 08:25 --> 08:28if I told you that if
  • 08:28 --> 08:31I wrapped my necktie around my head, it would
  • 08:31 --> 08:34help the arthritis in my knees,
  • 08:34 --> 08:35that's not biologically plausible.
  • 08:35 --> 08:37There's no real reason to
  • 08:37 --> 08:39think that that should work,
  • 08:39 --> 08:41so we don't pay much attention to that.
  • 08:41 --> 08:44But there are lots of examples
  • 08:44 --> 08:45of things that seem
  • 08:45 --> 08:47biologically plausible, for example,
  • 08:47 --> 08:49we know that as you age,
  • 08:49 --> 08:51there's more oxidative stress in your
  • 08:51 --> 08:54body and that oxidative stress might
  • 08:54 --> 08:56lead to some of the symptoms of aging
  • 08:56 --> 08:58like arthritis and stuff.
  • 08:58 --> 09:00We also have a chemical called
  • 09:00 --> 09:03vitamin E which is an antioxidant,
  • 09:03 --> 09:05and well reported as an antioxidant.
  • 09:05 --> 09:06It's biologically plausible,
  • 09:06 --> 09:08then that vitamin E would be
  • 09:08 --> 09:10good at helping against aging.
  • 09:10 --> 09:12Maybe might prevent heart
  • 09:12 --> 09:14attacks and things like that.
  • 09:14 --> 09:16Now a lot of people stop there.
  • 09:16 --> 09:18They say, oh that's biologically plausible.
  • 09:18 --> 09:20Oxidation is bad,
  • 09:20 --> 09:21antioxidant is good, vitamin E
  • 09:21 --> 09:23is cheap, it's at my drugstore.
  • 09:23 --> 09:24There's very limited side effects.
  • 09:24 --> 09:25You know this is great.
  • 09:25 --> 09:27It helps to confirm a belief that
  • 09:27 --> 09:30many of us want to be true that we
  • 09:30 --> 09:32can take charge of our lives without
  • 09:32 --> 09:34paying pharmaceutical companies and
  • 09:34 --> 09:35without having side effects.
  • 09:35 --> 09:38So there's a lot going for vitamin E,
  • 09:38 --> 09:39but let me tell you what
  • 09:39 --> 09:41happened with Vitamin E.
  • 09:41 --> 09:42They did a randomized trial of vitamin
  • 09:42 --> 09:45E and people who are at risk of heart
  • 09:45 --> 09:47disease and actually found not only
  • 09:47 --> 09:48was there no difference in
  • 09:48 --> 09:50the rate of heart attacks,
  • 09:50 --> 09:51the people taking vitamin
  • 09:51 --> 09:53E compared to placebo,
  • 09:53 --> 09:54but the people taking vitamin E
  • 09:54 --> 09:56had more heart failure.
  • 09:56 --> 09:58Statistically more heart failure than
  • 09:58 --> 10:00those taking placebo and again and again
  • 10:00 --> 10:01in medicine
  • 10:01 --> 10:02we see biologic plausibility,
  • 10:02 --> 10:04and actual efficacy getting untied.
  • 10:04 --> 10:06So what I tell people is that
  • 10:06 --> 10:08biologically plausible thing that you
  • 10:08 --> 10:10read about, like oh this is interesting,
  • 10:10 --> 10:12it works in cell culture,
  • 10:12 --> 10:14the mice seem to respond to this
  • 10:14 --> 10:17and it all sort of makes sense
  • 10:17 --> 10:19with how we understand the world,
  • 10:19 --> 10:21that's great, but that's only the beginning.
  • 10:21 --> 10:23You really want to see that randomized trial,
  • 10:23 --> 10:24not because
  • 10:24 --> 10:26I'm the kind of guy who
  • 10:27 --> 10:29I'm just following the rules and
  • 10:29 --> 10:31everything needs a randomized trial,
  • 10:31 --> 10:32it's because we've been burned
  • 10:32 --> 10:33so many times before,
  • 10:33 --> 10:36and I think that's what people don't realize.
  • 10:36 --> 10:37It's not like jumping
  • 10:37 --> 10:38through an arbitrary hoop.
  • 10:38 --> 10:40We've been wrong a lot when it
  • 10:40 --> 10:41comes to biologic plausibility,
  • 10:41 --> 10:43so I really do tell people
  • 10:43 --> 10:44we want a randomized trial.
  • 10:44 --> 10:47And if you want to be really sure you're not
  • 10:47 --> 10:49swallowing some patent medicine,
  • 10:49 --> 10:52you want to see a replication of that study.
  • 10:52 --> 10:54You want to see more than one study
  • 10:54 --> 10:56showing the same thing and ideally
  • 10:56 --> 10:58studies done by different people.
  • 10:58 --> 11:00You know different groups across the country
  • 11:00 --> 11:02or in different countries in the world.
  • 11:02 --> 11:04That's how you build an evidence base.
  • 11:04 --> 11:05And of course,
  • 11:05 --> 11:07that's what doctors jobs are, right?
  • 11:07 --> 11:09So one of the easiest things you
  • 11:09 --> 11:11can do if you have a trusted
  • 11:11 --> 11:12healthcare provider in your life,
  • 11:12 --> 11:16it is our job to be doing this and
  • 11:16 --> 11:17ask them. Talk to them.
  • 11:17 --> 11:20We're often excited to talk to you
  • 11:20 --> 11:22about what's real and what's not,
  • 11:22 --> 11:23and again,
  • 11:23 --> 11:25just hear it with an
  • 11:25 --> 11:27open mind.
  • 11:27 --> 11:30In terms of the information of looking
  • 11:30 --> 11:32for randomized control trials,
  • 11:32 --> 11:33especially that are all
  • 11:33 --> 11:35going in the same direction,
  • 11:35 --> 11:38because we've all seen randomized
  • 11:38 --> 11:40control trials that then are disproven
  • 11:40 --> 11:43by other randomized control trials.
  • 11:43 --> 11:44But you know, Perry,
  • 11:44 --> 11:46it's so difficult for the general
  • 11:46 --> 11:48public to actually access good
  • 11:48 --> 11:49randomized control trials.
  • 11:49 --> 11:52They're not really going to pubMed and
  • 11:52 --> 11:54searching the medical literature and
  • 11:54 --> 11:57looking at things with a critical eye.
  • 11:57 --> 12:00And in terms of talking to their doctor,
  • 12:00 --> 12:03that's certainly a great way to start.
  • 12:03 --> 12:05But there are also quote doctors
  • 12:05 --> 12:07who you can find on line who
  • 12:07 --> 12:08are spewing misinformation.
  • 12:08 --> 12:12So how do you kind of get around that?
  • 12:13 --> 12:16You've got to be careful,
  • 12:16 --> 12:18really anything that comes from social media,
  • 12:18 --> 12:20whether it's YouTube or Twitter.
  • 12:20 --> 12:22And hey, I'm on Twitter,
  • 12:22 --> 12:24but you do have to be careful
  • 12:24 --> 12:26because of the echo chamber effect.
  • 12:26 --> 12:29Someone can sort of wear the mantle of
  • 12:29 --> 12:31authority on social media based on sort
  • 12:31 --> 12:34of the number of followers and stuff
  • 12:34 --> 12:36that they have and that might make what
  • 12:36 --> 12:38they're saying seem more believable,
  • 12:38 --> 12:40when in fact it's not.
  • 12:40 --> 12:43And so you know, social media is fun.
  • 12:43 --> 12:44And interesting and a great
  • 12:44 --> 12:46place to share pictures.
  • 12:46 --> 12:47It's not where I recommend
  • 12:47 --> 12:49people do their research
  • 12:49 --> 12:50for medical questions.
  • 12:50 --> 12:51There are some absolutely wonderful
  • 12:51 --> 12:53medical reporters out there.
  • 12:53 --> 12:54So if you don't want to read the
  • 12:56 --> 12:58primary literature and
  • 12:58 --> 13:01pick up your copy of the New
  • 13:01 --> 13:02England Journal Medicine,
  • 13:02 --> 13:03there's some great science and
  • 13:03 --> 13:05medicine reporters out there.
  • 13:05 --> 13:07You want to look for reporters
  • 13:07 --> 13:08that that's their beat.
  • 13:08 --> 13:10Because of the slow death
  • 13:10 --> 13:13of the newspaper industry in America
  • 13:13 --> 13:15you get a lot of times the
  • 13:15 --> 13:17science and health, and
  • 13:17 --> 13:18even sports reporters are all
  • 13:18 --> 13:20the same person in some outlets.
  • 13:20 --> 13:22So you want to look for someone whose
  • 13:22 --> 13:24job is to write about health and medicine.
  • 13:24 --> 13:26They are often very well trained
  • 13:26 --> 13:27and are good nuanced
  • 13:27 --> 13:29and if you're
  • 13:29 --> 13:30reading about a new drug,
  • 13:30 --> 13:32a new treatment, you want to read
  • 13:32 --> 13:34from a couple of different people.
  • 13:38 --> 13:39There's some great writing,
  • 13:39 --> 13:40for example, in the Atlantic,
  • 13:40 --> 13:42the science section of the New York
  • 13:42 --> 13:44Times has always been very strong.
  • 13:44 --> 13:47Do they get it right 100% of the time?
  • 13:47 --> 13:47No,
  • 13:47 --> 13:50but that's why you look for other articles.
  • 13:50 --> 13:51That being said,
  • 13:51 --> 13:53it is not impossible for laypeople to
  • 13:53 --> 13:56go into the real medical literature and
  • 13:56 --> 13:58in fact I have a course
  • 13:58 --> 14:00online here at Yale,
  • 14:00 --> 14:01which is free called
  • 14:01 --> 14:02Understanding Medical Research:
  • 14:02 --> 14:04Your Facebook friend is wrong.
  • 14:04 --> 14:06It's on the Coursera platform you
  • 14:06 --> 14:08can search for it and basically
  • 14:08 --> 14:10it is an online course of 15
  • 14:10 --> 14:13minute lectures that you can watch
  • 14:13 --> 14:14over your lunch break
  • 14:14 --> 14:16where I teach you how to find a
  • 14:16 --> 14:18actual medical article,
  • 14:18 --> 14:21go to pub Med and how to find it,
  • 14:21 --> 14:22how to read it,
  • 14:22 --> 14:24and how to interpret the results.
  • 14:24 --> 14:25So if any of the listeners
  • 14:25 --> 14:28really want to get deep into this,
  • 14:28 --> 14:30really want to take that next step
  • 14:30 --> 14:31to understanding medical research.
  • 14:31 --> 14:32it's accessible you don't need
  • 14:32 --> 14:33a degree in chemistry.
  • 14:33 --> 14:35You don't need to remember calculus,
  • 14:35 --> 14:37you just need some logical thinking skills,
  • 14:37 --> 14:40and intuition so a little pitch for that course. It's free.
  • 14:40 --> 14:42And it's so
  • 14:42 --> 14:43important for people really to
  • 14:43 --> 14:46do your own research and be
  • 14:46 --> 14:48vigilant about it so that you're not
  • 14:48 --> 14:50taking other people's word for it.
  • 14:50 --> 14:52You're going to the source and
  • 14:52 --> 14:53knowing how to interpret that.
  • 14:53 --> 14:55We're going to take a short
  • 14:55 --> 14:57break for a medical minute,
  • 14:57 --> 14:58but please stay tuned to learn
  • 14:58 --> 15:00more about understanding medical
  • 15:00 --> 15:01research with my guest Doctor
  • 15:01 --> 15:02Perry Wilson.
  • 15:02 --> 15:05Support for Yale Cancer Answers
  • 15:05 --> 15:08comes from AstraZeneca, working to
  • 15:08 --> 15:11eliminate cancer as a cause of death.
  • 15:11 --> 15:13Learn more at astrazeneca-us.com.
  • 15:15 --> 15:17This is a medical minute about
  • 15:17 --> 15:19survivorship. Completing treatment for
  • 15:19 --> 15:22cancer is a very exciting milestone,
  • 15:22 --> 15:25but cancer and its treatment can be a life
  • 15:25 --> 15:28changing experience for cancer survivors.
  • 15:28 --> 15:30The return to normal activities and
  • 15:30 --> 15:32relationships can be difficult and
  • 15:32 --> 15:35some survivors face long term side
  • 15:35 --> 15:37effects resulting from their treatment,
  • 15:37 --> 15:38including heart problems,
  • 15:38 --> 15:40osteoporosis, fertility issues and
  • 15:40 --> 15:42an increased risk of second cancers.
  • 15:42 --> 15:45Resources are available to help
  • 15:45 --> 15:47keep cancer survivors well and
  • 15:47 --> 15:48focused on healthy living.
  • 15:48 --> 15:50More information is available
  • 15:50 --> 15:51at yalecancercenter.org.
  • 15:51 --> 15:55You're listening to Connecticut Public Radio.
  • 15:56 --> 15:58Welcome back to Yale Cancer Answers.
  • 15:58 --> 16:00This is doctor Anees Chagpar
  • 16:00 --> 16:03and I'm joined tonight by my guest
  • 16:03 --> 16:05doctor Perry Wilson and we're talking about
  • 16:05 --> 16:07understanding medical research.
  • 16:07 --> 16:10Perry, before the break
  • 16:10 --> 16:13we were talking about how much misinformation
  • 16:13 --> 16:16really is out there on the Internet,
  • 16:16 --> 16:18whether it's about covid or whether
  • 16:18 --> 16:20it's about cancer or whether
  • 16:20 --> 16:22it's about any topic really,
  • 16:22 --> 16:24whether it's medical or not.
  • 16:24 --> 16:26There is just so much misinformation
  • 16:26 --> 16:28that's propagated out there.
  • 16:28 --> 16:31So let's talk a little bit about some
  • 16:31 --> 16:35of the ways that we can mitigate that.
  • 16:35 --> 16:38You know, aside from being vigilant
  • 16:38 --> 16:39consumers of medical research,
  • 16:39 --> 16:42what else can be done to really
  • 16:42 --> 16:45kind of tamp down on all of the
  • 16:45 --> 16:48misinformation that's out there?
  • 16:50 --> 16:52This is a really hard problem
  • 16:52 --> 16:56that it's clear a lot of the social
  • 16:56 --> 16:58media companies are struggling with.
  • 16:58 --> 17:01As you know you see Facebook and Twitter
  • 17:01 --> 17:03for example, imposing essentially
  • 17:03 --> 17:05fact checking on some tweets,
  • 17:05 --> 17:07particularly surrounding hot button issues.
  • 17:07 --> 17:09For example, vaccination
  • 17:09 --> 17:11where they're literally
  • 17:11 --> 17:14blocking tweets, blocking posts that are
  • 17:14 --> 17:16construed by some of their
  • 17:16 --> 17:19moderators to be potentially anti VAX,
  • 17:19 --> 17:20for example this does
  • 17:20 --> 17:21strike some people as
  • 17:21 --> 17:23heavy handed.
  • 17:23 --> 17:24There are certainly concerns about
  • 17:24 --> 17:26is this going to have a chilling
  • 17:26 --> 17:28effect on speech?
  • 17:28 --> 17:30On the other side, people say that
  • 17:30 --> 17:32these are private companies that
  • 17:32 --> 17:35can do whatever they want
  • 17:35 --> 17:36within the confines of their own platform.
  • 17:37 --> 17:39It strikes me though,
  • 17:39 --> 17:41that it's a bit of whack-a-mole
  • 17:41 --> 17:43and that these efforts
  • 17:43 --> 17:44are reactive rather than proactive.
  • 17:44 --> 17:48What can we do to be more proactive?
  • 17:48 --> 17:50One of the things I've
  • 17:50 --> 17:52seen that's a little clever
  • 17:52 --> 17:54is Twitter has been generating a little
  • 17:54 --> 17:56pop up when you retweet an article
  • 17:56 --> 17:58if it notes that you haven't
  • 17:58 --> 18:00actually read the article.
  • 18:04 --> 18:06That's a whole other topic, right?
  • 18:06 --> 18:08Like how it knows
  • 18:08 --> 18:10whether you've opened the other
  • 18:10 --> 18:12you didn't look at the article,
  • 18:12 --> 18:14but I think what it's doing is
  • 18:14 --> 18:16the article will have a tweet with a link
  • 18:20 --> 18:22and it knows if you've clicked that
  • 18:22 --> 18:24link 'cause it's within Twitter.
  • 18:24 --> 18:27If you haven't and you click retweet,
  • 18:27 --> 18:29it's been saying, hey,
  • 18:29 --> 18:32do you want to maybe read this
  • 18:32 --> 18:33article before you retweet it?
  • 18:34 --> 18:36That is an interesting strategy because
  • 18:36 --> 18:39it takes the emotion slightly down.
  • 18:39 --> 18:41There's a tendency for people
  • 18:41 --> 18:43to share and retweet things that
  • 18:43 --> 18:44are emotionally activating.
  • 18:44 --> 18:46Whether they make you angry
  • 18:46 --> 18:48or make you happy.
  • 18:48 --> 18:50Whether it's a mama cat
  • 18:50 --> 18:51cuddling with baby kittens,
  • 18:51 --> 18:54or whether it's someone saying
  • 18:54 --> 18:56something terrible and caught on tape.
  • 18:56 --> 18:58Both of those strong reactions
  • 18:58 --> 19:00elicit a lot of engagement and
  • 19:00 --> 19:02trying to remove that a little bit,
  • 19:02 --> 19:04giving people a little extra time to say, wait
  • 19:04 --> 19:07do you really want to put this out there?
  • 19:07 --> 19:09Do you want to share this?
  • 19:09 --> 19:11Might help a little bit.
  • 19:13 --> 19:15My hope lies a lot with
  • 19:15 --> 19:16the younger generations.
  • 19:16 --> 19:16Honestly,
  • 19:16 --> 19:18who are growing up in this
  • 19:18 --> 19:19environment and in my opinion,
  • 19:19 --> 19:22are actually quite a bit more savvy.
  • 19:22 --> 19:24I agree with you.
  • 19:24 --> 19:26I think that even our patients who come in,
  • 19:26 --> 19:30many times the older
  • 19:30 --> 19:32generation sometimes will have heard
  • 19:32 --> 19:35things like sugar feeds cancer or
  • 19:35 --> 19:39it can stop all cancer and some of our
  • 19:39 --> 19:41younger patients or patients families,
  • 19:41 --> 19:44it's remarkable they will have gone
  • 19:44 --> 19:47to the literature and be quizzing
  • 19:47 --> 19:50you on the latest study that was
  • 19:50 --> 19:53published in the New England Journal
  • 19:53 --> 19:56or what just came out at ASCO.
  • 19:56 --> 19:59So it really does behoove us to
  • 19:59 --> 20:03be wary of what's out there now.
  • 20:03 --> 20:06Are there certain places where
  • 20:06 --> 20:09people should go to kind of look
  • 20:09 --> 20:11at the literature if they don't go
  • 20:11 --> 20:14to pubMed directly and again,
  • 20:14 --> 20:17your course will tell them how they can
  • 20:17 --> 20:19actually go to the primary literature,
  • 20:19 --> 20:21but are there certain websites
  • 20:21 --> 20:24that you think are
  • 20:24 --> 20:26generally pretty reliable versus
  • 20:26 --> 20:29kind of taking the latest weird
  • 20:29 --> 20:31theory that's out there?
  • 20:31 --> 20:33As I mentioned,
  • 20:33 --> 20:35some of the large news organizations
  • 20:35 --> 20:37that have dedicated science
  • 20:37 --> 20:39writers are a great tool,
  • 20:39 --> 20:42but if you really want dedicated sites,
  • 20:42 --> 20:44there's a couple of good sites,
  • 20:44 --> 20:46Medscape.com, andfFull disclosure,
  • 20:46 --> 20:49I have a weekly column on medscape.com
  • 20:49 --> 20:52but Medscape.com is a medical news website.
  • 20:52 --> 20:55It's an offshoot of WebMD which
  • 20:55 --> 20:57actually does a very nice job.
  • 20:57 --> 20:59They have dedicated reporters covering
  • 20:59 --> 21:01the latest medical studies,
  • 21:01 --> 21:02which is quite good, stat.com,
  • 21:02 --> 21:05which is another medical news focused
  • 21:05 --> 21:07website is quite good and
  • 21:07 --> 21:10as you're exploring there
  • 21:10 --> 21:12are other sites as well.
  • 21:12 --> 21:15And when you're exploring a site,
  • 21:15 --> 21:18I think one of the real hints as
  • 21:18 --> 21:20you're reading through as a reader to
  • 21:20 --> 21:23know about the quality here is
  • 21:23 --> 21:26look for emotion in the writing and if
  • 21:26 --> 21:30there is too much be worried.
  • 21:30 --> 21:32Real medical reading is often not
  • 21:32 --> 21:33the most exciting thing.
  • 21:33 --> 21:35This is not Hemingway.
  • 21:35 --> 21:37This is reporting on often nuanced
  • 21:37 --> 21:40medical studies and drugs that have
  • 21:40 --> 21:43some benefit but some risks.
  • 21:43 --> 21:46And if your reporting is expressive of that,
  • 21:46 --> 21:49then it's good reporting, latest
  • 21:49 --> 21:51breakthrough, Miracle Cure, New Silver Bullet.
  • 21:51 --> 21:54The end of blank diseases in sight.
  • 21:54 --> 21:56These highly emotional headlines are
  • 21:56 --> 21:59a good red flag that you're not on a
  • 21:59 --> 22:02site that's taking this very seriously.
  • 22:02 --> 22:05I mean it goes back to the old
  • 22:05 --> 22:08adage of if it sounds too good to be true,
  • 22:08 --> 22:11it likely is, and so I'll add to your list.
  • 22:11 --> 22:15I think that there are some
  • 22:15 --> 22:16good professional organizations
  • 22:16 --> 22:19that people can turn to.
  • 22:19 --> 22:23ASCO has some websites that are dedicated
  • 22:23 --> 22:24to patient information, cancer.net,
  • 22:24 --> 22:28for example, the American Cancer Society.
  • 22:28 --> 22:31Cancer.org has some great information
  • 22:31 --> 22:35and there are a variety of associations
  • 22:35 --> 22:39for whatever cancer my ail you,
  • 22:39 --> 22:43whether it's breast cancer or leukemia
  • 22:43 --> 22:47or colon and rectal cancer.
  • 22:47 --> 22:48Go to the
  • 22:48 --> 22:50organizations that are really
  • 22:50 --> 22:52doing the research into this,
  • 22:52 --> 22:54because very often they will
  • 22:54 --> 22:57publish that data and a good hint
  • 22:57 --> 22:59is to look for the footnotes,
  • 22:59 --> 23:02because very often they will lead you
  • 23:02 --> 23:05to the studies and to the literature
  • 23:05 --> 23:07that they're citing in making the
  • 23:07 --> 23:10claim that they they have so and so.
  • 23:10 --> 23:13We have some of that data for
  • 23:13 --> 23:16cancer, and I think that
  • 23:16 --> 23:18because cancer has been around
  • 23:18 --> 23:20for a long time,
  • 23:20 --> 23:23a lot of the misinformation now I think it's
  • 23:23 --> 23:26starting to die down. There still are some
  • 23:26 --> 23:29old wives tales out there like
  • 23:29 --> 23:31sugar feeds cancer or tumeric
  • 23:31 --> 23:32will cure all cancers.
  • 23:32 --> 23:34PS for our listeners,
  • 23:34 --> 23:38neither of those two statements are true.
  • 23:38 --> 23:39But for novel diseases,
  • 23:39 --> 23:42things like Covid, it's a lot harder.
  • 23:42 --> 23:44I think for people,
  • 23:44 --> 23:46especially initially to weed
  • 23:46 --> 23:48out some of that misinformation.
  • 23:48 --> 23:50So what are some of the misinformation
  • 23:50 --> 23:53hot buttons that you found
  • 23:53 --> 23:55out there that are propagated
  • 23:55 --> 23:57that you'd like to dispel?
  • 23:57 --> 23:58Oh my
  • 23:58 --> 24:00gosh, Covid has really given
  • 24:00 --> 24:03those of us who like to correct
  • 24:03 --> 24:05the record in Medicine a lot to do.
  • 24:05 --> 24:08It's been a full time job in Covid
  • 24:08 --> 24:11and I think in part it gets back to
  • 24:11 --> 24:14that idea of motivated reasoning.
  • 24:14 --> 24:15We all hate this pandemic.
  • 24:15 --> 24:18Every single one of us wants
  • 24:18 --> 24:20nothing more than for it to be over,
  • 24:20 --> 24:23and if there were some simple cure
  • 24:23 --> 24:25that was cheap and effective and
  • 24:25 --> 24:27worked 100% of the time oh my gosh,
  • 24:27 --> 24:28it would be amazing.
  • 24:28 --> 24:31We all want that and so you
  • 24:31 --> 24:33had this proliferation of data
  • 24:33 --> 24:34coming out early in Covid
  • 24:34 --> 24:37and I think that's sort of prototypical.
  • 24:37 --> 24:39One was the study surrounding
  • 24:39 --> 24:39Hydroxychloroquine which
  • 24:39 --> 24:41is an anti-malarial drug
  • 24:41 --> 24:42that's also used for lupus,
  • 24:42 --> 24:44which is an autoimmune disease.
  • 24:44 --> 24:46An old drug that with a lot of
  • 24:46 --> 24:48experience with and the truth is
  • 24:48 --> 24:50relatively safe as some drugs go,
  • 24:50 --> 24:52although there can be risks of cardiac
  • 24:52 --> 24:54arrhythmias in people who take it,
  • 24:54 --> 24:55but it's not
  • 24:55 --> 24:58the most toxic drug in the world,
  • 24:58 --> 25:00and some early studies,
  • 25:00 --> 25:0110-20 people suggested that maybe
  • 25:01 --> 25:03they get a little better faster now.
  • 25:03 --> 25:05Skip ahead and I'll tell you that large
  • 25:05 --> 25:07clinical trials have been done
  • 25:07 --> 25:09now I think we're at 9 or 10 large
  • 25:09 --> 25:11clinical trials of hydroxychloroquine.
  • 25:11 --> 25:13All of them negative.
  • 25:14 --> 25:16That's fairly well confirmed,
  • 25:16 --> 25:18but initially there was this
  • 25:18 --> 25:19huge enthusiasm surrounding it.
  • 25:19 --> 25:22And to the point where you know
  • 25:22 --> 25:23people were stockpiling the
  • 25:23 --> 25:25stuff people were taking it,
  • 25:25 --> 25:29and I think it fed what we wanted to believe,
  • 25:29 --> 25:32which was that there was a solution.
  • 25:32 --> 25:35And unfortunately the truth
  • 25:35 --> 25:37it's rare that things work that well.
  • 25:37 --> 25:38It's just unlikely that no
  • 25:38 --> 25:40matter what comes down the pipe,
  • 25:40 --> 25:42the cure is going to be something
  • 25:42 --> 25:44in your medicine cabinet that
  • 25:44 --> 25:46just doesn't happen very often.
  • 25:46 --> 25:48The exception being maybe
  • 25:48 --> 25:49like scurvy and vitamin C,
  • 25:49 --> 25:52and even that took a randomized trial
  • 25:52 --> 25:54to figure out back on the high seas.
  • 25:54 --> 25:57So that was certainly a big one.
  • 25:58 --> 25:59What's more concerning,
  • 25:59 --> 26:02I think even then the medication stuff
  • 26:02 --> 26:04is the vaccination issues in covid,
  • 26:04 --> 26:05so these are new vaccines.
  • 26:05 --> 26:08A lot of vaccine hesitancy at baseline
  • 26:08 --> 26:10kind of brought up to a degree by
  • 26:10 --> 26:12the fact that there are some new
  • 26:12 --> 26:14technologies in these vaccines,
  • 26:14 --> 26:15like MRNA technology,
  • 26:15 --> 26:17which I will point out,
  • 26:17 --> 26:19is new in the sense that we've never
  • 26:19 --> 26:21done it broadscale treatment with it,
  • 26:21 --> 26:22but is not new.
  • 26:22 --> 26:24It's actually been in clinical
  • 26:24 --> 26:26use for more than a decade now,
  • 26:26 --> 26:28but still new stuff for people,
  • 26:28 --> 26:30and we're seeing a lot of misinformation
  • 26:30 --> 26:32about what is in the vaccine,
  • 26:32 --> 26:34how the trials were done.
  • 26:34 --> 26:36I was reading on social media that
  • 26:36 --> 26:39people were saying that the trials
  • 26:39 --> 26:41were inoculating their volunteers with
  • 26:41 --> 26:43Covid when they walked through the door,
  • 26:43 --> 26:45which is a trial design
  • 26:45 --> 26:46that is quite controversial
  • 26:46 --> 26:49and is not what happened in these
  • 26:49 --> 26:51large clinical trials.
  • 26:51 --> 26:54And the problem of course with this
  • 26:54 --> 26:56misinformation is that this really does hurt
  • 26:56 --> 26:58our ability to end this pandemic, because
  • 26:58 --> 27:01the vaccines are the best tools we have.
  • 27:03 --> 27:05There's lots of misinformation
  • 27:05 --> 27:07around masks as well.
  • 27:07 --> 27:09You still see posts saying that
  • 27:09 --> 27:11masks reduce your blood oxygen content
  • 27:11 --> 27:12or increase the carbon dioxide content.
  • 27:12 --> 27:13You're a surgeon.
  • 27:13 --> 27:15My wife is a surgeon.
  • 27:15 --> 27:17She is wearing a mask for
  • 27:17 --> 27:188 hours a day, every day,
  • 27:18 --> 27:21and her oxygen level is perfectly fine.
  • 27:21 --> 27:22She doesn't get lung disease or
  • 27:22 --> 27:24infections that's still out there,
  • 27:24 --> 27:25and it really does
  • 27:25 --> 27:26hurt our ability
  • 27:26 --> 27:28to end the pandemic faster.
  • 27:28 --> 27:29We're kind of shooting ourselves
  • 27:29 --> 27:31in the foot with this stuff.
  • 27:32 --> 27:33The other big
  • 27:33 --> 27:34piece of misinformation, I
  • 27:34 --> 27:36was watching the news the other
  • 27:36 --> 27:38day and they were saying that
  • 27:38 --> 27:4233% of Americans that
  • 27:42 --> 27:45were surveyed in this one poll
  • 27:45 --> 27:49felt that Covid was not real.
  • 27:49 --> 27:51And you kind of shake your head and
  • 27:51 --> 27:53you say we're now over half a million
  • 27:53 --> 27:55people dead in this country of a
  • 27:55 --> 27:57disease that you think is not real.
  • 28:01 --> 28:02And for people, including myself,
  • 28:02 --> 28:04and I'm sure you as well have cared for
  • 28:04 --> 28:06these patients in the hospital that
  • 28:06 --> 28:08it's particularly painful to hear that.
  • 28:08 --> 28:10And of course, some of us have
  • 28:10 --> 28:12lost loved ones to the disease.
  • 28:12 --> 28:14But you know, again
  • 28:14 --> 28:16I'm trying to do my best to
  • 28:16 --> 28:17understand where this comes from,
  • 28:17 --> 28:19and I do think it comes
  • 28:19 --> 28:21from a place of desire.
  • 28:21 --> 28:23Why do people believe that it's not real?
  • 28:24 --> 28:26Because they don't want it to be real,
  • 28:26 --> 28:28and if we just ask people,
  • 28:28 --> 28:29be aware of your motivations
  • 28:29 --> 28:32and be skeptical of data that only
  • 28:32 --> 28:34confirms what you want to be true,
  • 28:34 --> 28:36people will be in good shape.
