Oncology
and
Big
Data

2. Opportuni5es
• Big
Data
in
Cancer
– Mobility
and
pervasive
compu5ng
– Social
data
– NGS
– Imaging
(fMRI,
CT
scans)
• EHR
integra5on
– Analy5cs
based
on
clinical
data
– Decision
support
3. Challenges
• EHR
–
we
need
synop5c
and
seman5c
data
to
support
precision
medicine
• EHR
–
Truly
automated
and
useful
decision
support
• Handling
and
analyzing
big
data
• Appropriate,
open
access
to
pa5ent-‐derived
big
data
• Incorpora5ng
social
data
• Mobile
compu5ng
4. GeMng
Big
• Big
Data
is
about
emergent
proper5es
• Big
Data
changes
the
sta5s5cal
paradigm
–
rather
than
modeling
whether
the
sample
is
representa5ve
of
the
popula5on,
you
have
all
the
data
from
the
popula5on
• How
do
we
combine
systems
biology
and
social
data
with
therapeu5cs
and
big
data
from
healthcare
providers
?
5. -‐omics,
clinical,
nutri5on,
exposure
• Teasing
apart
the
factors
contribu5ng
to
risk
and
therapeu5c
efficacy
is
complicated!
• Sources
of
data
we
would
like
to
have
across
all
pa5ents:
Genomic
data
Treatment
Outcomes
Microbiome
data
Metabolomics
Exposure
data
Nutri8on
Labs
Behavior
Medical
History
6. -‐omics,
clinical,
nutri5on,
exposure
• And
of
course
we
would
like
all
these
data
consistent
and
reliable!

8. Examples
of
current
solu5ons
• Mobile
ePROs,
either
at
home
or
in
the
clinic
• Care
diaries
on
tablets
–
response,
recovery
• Integra5on
of
NLP
and
phenotype
algorithms
at
the
point
of
care
• Integra5on
of
clinically
ac5onable
genomic
variants
into
EHR
(think
Hercep5n
and
HER2)
• Decision
support
for
infec5ous
diseases
based
on
social
network
and
GPS
–
not
just
for
MRSA
9. Mobile
compu5ng
• Measuring
depression,
pain
and

Mobilyze
is
a
mobile
applica5on
aimed
at
trea5ng
major
depression
and
includes
• Didac5c
Content
(text,
video,
audio)
aimed
in
providing
educa5on
about
behavior
change
strategies
• Interac5ve
Tools
that
assist
in
implemen5ng
changes
• No5fica5ons
that
provide
reminders
• Feedback
that
provide
insight.

11. Context
Awareness
• Context
awareness
refers
to
the
idea
that
computers
can
both
sense,
and
react
based
on
their
environment.
• A
second
aim
of
the
Mobilyze
project
is
to
harness
sensor
data
from
user
phones
to
develop
models
that
can
detect
treatment
relevant
states
in
real
5me,
which
can
then
be
used
to
posi5vely
reinforce
treatment
congruent
behavior
and
provide
assistance
when
need
is
detected.

13. Purple
Robot
• A
full
real-‐5me
sensor
data
acquisi5on
placorm
for
collec5ng
informa5on
about
the
user
and
their
immediate
surroundings.
Purple
Robot
provides
– Full
access
to
the
Android
sensor
framework
(e.g.
the
accelerometer,
gyroscope,
pressure
sensor,
light
sensor,
etc.)
– Access
to
other
device
informa5on
(e.g.
badery
level,
running
soeware
&
apps,
and
hardware
informa5on).
– Op5ons
to
scan
for
external
devices
such
as
wireless
access
points
and
visible
Bluetooth
devices.
– Loca5on
sensors
that
use
the
built-‐in
GPS
and
cellular
triangula5on
op5ons
to
map
the
user’s
loca5on.
– Local
environmental
data
sources
such
as
solar
event
5ming
(sunrise
&
sunset)
and
weather
condi5ons.
– Communica5on
paderns,
including
phone
logs
and
text-‐
message
transcripts.
– Cryptographic
anonymiza5on
of
personally-‐iden5fiable
informa5on
before
it
leaves
the
device.

14. EHR
Integra5on
• EHR
systems
are
rela5vely
closed
• Implemen5ng
two
way
integra5on
is
difficult
• Innova5on
using
EHRs
is
difficult
• Example:
Lightweight
coupling
of
electronic
pa5ent
reported
outcomes
(ePROs)

17. Integration with eNOTIS
Informatics
Ø eNOTIS: Open source
web-based subject
registration system
Ø Meets federal guidelines
for electronic reporting
and addresses a
mandate that accrual
information be tracked,
validated, and reported.
https://enotis.northwestern.edu/login
https://github.com/NUBIC/eNOTIS

18. Delivery on an iPad
Ø eCapture is a web-based
system delivers forms for
administrator or patient
facing data collection and
it is linked to eNOTIS.
Ø Information, collected
through these systems,
can be linked with other
clinical information
available in the EHR
