Unraveling Your Genetics Through Precision Medicine | Lincoln Nadauld | TEDxRiverton


in other settings I have commented that

one in three of us will be diagnosed

with cancer in our lifetimes one in

three is a big number so look to your

left and look to your right if it’s not

you it will be the person on your left

or on your right and if it’s not you or

your neighbor it will be a brother or

sister or it will be a parent or child

cancer is an insidious disease it robs

patients of their appetite their energy

their strength their stamina it robs

them of their independence and in many

cases their happiness it’s an unfair

disease and it is no respecter of

persons so one in three is a big enough

number that we ought to just plan on it

in fact better yet let’s start thinking

about how we can help our friends

families and neighbors when that

diagnosis comes what can we do what will

we do to help them how can we help

ourselves well I think a clue comes from

our furry mammalian friend the house

mouse and you may be wondering what in

the world does the house Mouse have to

do with how we’re going to attack cancer

well it turns out that we share about

95% of our DNA in common with mice

that’s another big number 95% I think

there’s a couple of things to learn

there the first is apparently it doesn’t

take much additional DNA to learn speech

or how to walk uprightly more

importantly and and and maybe more

seriously it means there’s probably

something that we can learn from mice

and there is recently a scientific

publication looked at two groups of mice

and these mice develop cancer and in the

first group mice that developed cancer

were placed off to the side alone by

themselves separate from the rest of

mice in the second group when a mouse

developed cancer it was placed in a

group of mice and it became the mouse in

the middle of that

would you like to guess which mice lived

longer and were stronger and did better

yeah absolutely it was the mouse in the

middle was the mouse that was left in

the group those mice lived longer and

we’re stronger and did better when mice

are engaged and have social interaction

they do a lot better and we who are 95%

identical to mice are no different so

that’s our first clue in in asking what

can we do when that diagnosis comes well

let’s make our friends family and

neighbors the mouse in the middle

think of the power of that statement the

mouse in the middle let’s surround them

with the social network that they need

let’s empower them let’s lift them up

and strengthen them if sick place the

mouse in the middle if sick place the

friend family member or neighbor in the

middle I’ve seen this in action one of

the great joys of my life is the

precious opportunity I have to take care

of cancer patients I love it I get to

meet people when they become the

one-in-three sometimes we have an

opportunity to cure and that can be

exhilarating and sometimes we don’t have

the opportunity to care and that’s

really hard I spend time counseling and

hugging and laughing and grieving and I

love all of that I’ve learned that

there’s a lot that happens during that

time I’ve learned that the relationship

between a cancer patient and their

doctor is like nothing else in medicine

and I think maybe like nothing else in

life so it is through that lens that I

have watched patients I have seen those

who are the mouse in the middle I get to

sit on the other side of that exam room

door in the clinic and I see patient

after patient come in and it’s amazing

those who are the mouse in the middle

it’s easy to spot they come and they’re

always accompanied by someone and

usually it’s the same person at every

single visit it’s a spouse or a devoted

child it’s a parent or a sibling or a

neighbor and often they come in groups

and when they come it they look like

they’re coming for a day-long event they

come carrying bags and magazines and

drinks and treats and snacks and they’ve

got their

iPads and they’re ready to go and

they’re wearing matching t-shirts and

they’ve got wristbands and headbands and

and it’s inspiring the point is they

come in support they come with their

arms around that person ready to support

them and those who come and support are

there to help listen to the plan they’re

there to help think through what’s

happening they’re there to share in the

good news and they’re there for the bad

news they’re there to help think through

decisions and sometimes they’re there to

help lighten the mood when that’s needed

in contrast I have seen patients come

who are not the mouse in the middle and

they have little or no support and

that’s tough that strength in numbers is

missing that Mouse in the midle

phenomenon is absent and it’s really

apparent now if you or someone you know

is that person that doesn’t have support

or for whatever reason has not wanted to

allow that support into your lives I

invite you to reach out and find a

friend we live in a world that where

it’s increasingly easy to become

isolated we interact through social

media and on digital devices we can have

a thousand friends at our fingertips but

we need one who will physically hold our

hand we can have hundreds of friends

online but whom would we call if we

needed a bowl of soup so I invite you to

reach out and find that friend I am

certain that there are people waiting

for the opportunity to experience this

with you I know that there is a friend

waiting for the privilege of standing

shoulder to shoulder with you when you

become the mouse in the middle you you

harness the power of an amazing social

network now the next step after that

after we have embedded ourselves and

surrounded ourselves with community

friends family and become this mouse in

the middle is that we want to get in the

middle of our medical care as well there

are several recent advances happening in

cancer care right now that are

absolutely transforming the way we treat

patients it’s like nothing we’ve ever

seen where

a confluence of science technology and

medical care that is allowing us to not

only surround people but target that

Mouse in the middle with precision and

let me just illustrate this point five

years ago if someone had been diagnosed

with lung cancer they would expect to

have a workup that in would include CT

scans and biopsies and pathology reports

and meeting with doctors and nurses and

then ultimately they would receive

chemotherapy and radiation well in many

cases that would work in some cases it

wouldn’t in the cases where it wouldn’t

the options after that become quite

limited today however five years later

there’s a much different scenario that

same patient diagnosed with lung cancer

would expect to have quite a different

workup now they would still have the

same CT scans and biopsies and meeting

with doctors and nurses but they would

also expect to have a really

comprehensive genomic analysis and

that’s a big word but it’s really cool

they can expect to have DNA pulled from

their tumor and looked at to find the

specific genes that were changed in

their tumor that caused just their tumor

to grow in a very individualized way in

addition they would expect to have a

whole protein analysis so now they have

genomic analyses proteomic analyses in

addition to all of these other things

and this new approach has a name it’s

called precision medicine and precision

medicine includes all of these things as

mentioned the CT scans health history

medications and now these new approaches

including looking at your DNA

immunotherapies and others this forms an

additional ring outside of that social

network now we have precise medical care

in addition to the social support and

the results are are terrific that lung

cancer patient that I mentioned

diagnosed five years ago would expect to

have a survival measured in months

that’s that’s tough to swallow today

that same on cancer patient if they have

certain genes or certain protein changes

they could expect to have a survival

measured in years or long

pretty terrific changes and there’s more

in addition to these targeted treatments

and DNA analyses there are new immune

treatments immune therapies we actually

recently have developed the ability to

awaken a patient’s own immune system to

recognize cancer and attack it as if it

were foreign but that’s pretty cool my

favorite example of this actually is a

drug that has recently been approved and

is available it’s given by IV and it’s

an antibody because it’s an antibody

it’s just like the antibodies that our

bodies make normally so it has very few

if any side effects and the way it works

is that cancer cells unfortunately are

pretty smart they have figured out how

to evade our natural immune systems and

they do this by putting proteins on

their surface so these immune cells have

these excuse me these cancer cells have

these little proteins on their surface

and when an immune cell comes in contact

that protein says everything here is

fine go away and that’s what happens and

then the tumors free to grow when we

give these immune therapies or

immunotherapies these antibodies come

and stick on those proteins and mask

them so that now an immune cell comes in

contact it doesn’t get that signal that

everything’s okay it actually recognizes

the cancer cell as foreign it attacks it

and eliminates it like it’s supposed to

do the results can be breathtaking we’re

seeing responses that we’ve never seen

before it’s it’s totally exciting now it

doesn’t work for everyone and there’s

lots left to do the point is precision

medicine immunotherapy this whole social

approach the cancer care is not your

father’s cancer medicine this is this is

a new era in every way and it’s totally

exciting now

the next step after being in the middle

of our social network and being

surrounded by precision medicine and

remembering a precision medicine really

is defined by medicine that is genomic

in nature takes into account our

molecular and personal information to

inform personalized health treatment

plans that that

the essence but it really is is reactive

and and that’s okay but as we engage

that precision medicine and social

network we see something very

interesting that happens which is this

target phenomenon and at the bullseye of

that target is the mouse in the middle

in other words we surround that mouse in

the middle of that patient with all of

the social support they need all of this

sophisticated healthcare and it’s all

focused on that single individual and

that’s exactly what we want that’s how

we get the best outcomes the only thing

that is better than treating cancer in

that way would be to prevent cancer and

that’s the next concept the next layer

which is precision health

let’s go beyond precision medicine which

is reactive and let’s pursue precision

health which is preventive and precision

health is really defined similarly to

precision medicine it’s the application

of precision medicine principles these

same genomic molecular personal health

discoveries but applied now to

populations with the with the goal that

we are going to keep people healthy as

long as possible we are going to help

patients live the healthiest lives

possible in the past precision health

has meant let’s do things like get our

cancer screenings and honestly that’s

the best thing that we can do when we

found when our friend or neighbor is

diagnosed

let’s not only surround them with social

support but let’s make sure that we

ourselves are getting the screenings we

need so that we don’t have now two

people with cancer right the only thing

worse than having one person that we

he’ll have to try to get through this

very difficult thing is to have two

people or three people so when we follow

precision health we do things like get

our mammograms when we’re 40 and get

colonoscopies when we turn 50 and wear

sunscreen and all of these practical

approaches increasingly we are seeing

that precision health also means getting

DNA testing imagine if we could draw

blood from everyone here tonight today

and then we could look and see if you

inherited genes from your parents that

would place you at risk for too

helping a cancer in your lifetime it

turns out 10% of all human cancers are

inherited they arise because they came

from a gene that you got from one of

your parents 10% that’s another big

number so imagine if we could prevent

all of those cancers that’s tens of

thousands it’s actually hundreds of

thousands of cancers a year in this

country alone that we could prevent and

that’s what’s coming is the opportunity

to add to our traditional screenings

this layer of molecular and DNA

screenings looking for people who have

inherited cancers well my my hope and my

belief is is that precision medicine and

precision health along with surrounding

the mouse in the middle with the social

network is the answer to how we treat

cancer I started by talking about the

one in three and one in three of us will

be diagnosed with cancer in our lifetime

when that diagnosis comes it can be

overwhelming our heads can spin and we

can be uncertain of what to do my hope

is that if that happens and when it

happens you’ll you’ll remember this

philosophy you’ll share what you know

with others you’ll place that Mouse in

the middle of this great Network make it

the bullseye

my hope is that you will make yourselves

the mouse in the middle of your own

social care your own precision health

care and your own preventive health care
