Agenda
• Defining Telemedicine • History • Successful Uses
• Our Project and outcomes • Regulatory Information • Requirements for Telegenetics • Current and Future state
Telemedicine
• Means "distance healing“.
• Derived from a Greek word "Tele" meaning "distance" and a Latin word "mederi" meaning "to heal“.
• Use a specific technology to provide healthcare services
Telemedicine is the future of global healthcare.
Telehealth vs Telemedicine?
Per WHO:
Telehealth-uses computer-assisted
telecommunications to support management,
surveillance, literature and access to medical
knowledge
Telemedicine-solely to diagnose and treat
patients
Used interchangeably by most
“TELEGENETICS PROVIDES HEALTHCARE WHERE THERE IS NONE AND IMPROVES THE HEALTH CARE WHERE THERE IS SOME”
History of Telemedicine
1905
William Einthoven transfers
electrocardiograms electronically
1960s
First used by NASA to monitor health of astronauts in space
1990s
Telemedicine matures; wide-
spread acceptance of teleradiology
practices
Now
Telemedicine seen as a viable means
for improving access, decreasing
costs.

“60-80 % of ER, urgent care, and doctors visits can be handled safely and effectively over the phone. -American Medical Association
? 11
“To date, no studies have identified any patient subgroup that does not benefit from, or is harmed by mental healthcare provided through remote video conferencing.”

Growth of Telemedicine Globally
$13.8 billion
2012 Market Size
$9.8 billion
2010 Market Size
278% Growth Rate Expected Between 2010-2019 Research
Advantages of Telegenetics
• Resource utilization
• Early intervention
• Avoids unnecessary transportation
• Community based care
• Medical education and research
• Cost saving
• Improved patient documentation
• Increased range of care and education.
Resource Utilization
• In underdeveloped countries doctor population ratio is 1:20000 in comparison to 1:500 in developed nations, and these doctors are not distributed equally.
• 80% of population lives in rural and semi urban areas.
• Telemedicine can help in cost effective utilization of meager resources and of the same time can decrease patient work load on few referral centers.
We look more like this
….than that

Gene Breakdown
Evaluation: Financial Impact
• Utilization patterns
• Missed work/school days
• Direct and indirect cost savings
• ROI
Early Intervention
• There are factors that inhibit the continuity of care. Issues such as geographic location, inclement weather, socioeconomic barriers.
• Patient apathy are significant factors that delay and even prevent the specialty care.
• By providing these sites with the ability to quickly access specialty consultation services.
• Patients are able to reap the benefits of early intervention while the health care system maintains quality service and clinical efficiency.
Avoids Unnecessary transportation
• Patient can discuss the issues on Video Conferencing with the consultant.
• Even the vital parameters and be captured with the help of devices and sent to doctor.
• Unnecessary referral and patient transport can be definitely avoided.
Community base Care
• People like to receive high quality care in their local community.
• This reduces travel time and related stresses associate with many referrals.
Barriers of Telecommunication
• Low or small bandwidth. • Neither telephone lines nor electricity in rural and
remote areas. • Satellite transmission can help but it is very costly. • Unstable electricity supply. • Patient’s fear and unfamiliarity. • Financial unavailability. • Lack of basic amenities. • Literacy rate and diversity in languages. • Quality aspect. • Government support.
Sporadic vs. Genetic
• Germline – the genes you are born with
– Can be passed on to relatives
– Does not mean that disease will happen
– Increased risk of disease
– There is no one “breast cancer gene”
• Somatic – changes in tumors that are acquired over time
– Can not pass on to relatives
– Can be tested as part of decision making for therapy for cancer
Germline vs Somatic Genetics
• Breast cancer <45
• Ovarian cancer cases (particularly high grade serous)
• Male Breast Cancer
• Breast and ovarian cancer in a single lineage
• 2 or more women with breast cancer <50
• Ashkenazi Jewish with breast or ovarian cancer
• Breast cancer < 60 and triple negative
• Bilateral breast cancer <60
• Pay attention to pancreatic cancer and high grade
prostate cancer
• Ashkenazi Jewish individuals?
Who should be considered for testing?
• Risk Assessment
• Disease Prevention
• Therapeutics
Germline genetic testing as a paradigm
for individualized care
BRCA1/2 as the prototype
Increased risk of other cancers:
Male breast cancer BRCA2>BRCA1
Pancreatic cancer BRCA2
Prostate cancer BRCA2
Melanoma BRCA2
Breast cancer: 50%-70%
Second primary breast cancer: 40%-50%
Ovarian cancer: 15-55% BRCA1>BRCA2
BRCA1/2-associated cancers: lifetime risk
Genetic testing has become complicated….
Single nucleotide polymorphism panels
• Not comprehensive sequencing of genes – such as BRCA1/2
• Not a stand alone for those with a strong family history
• Some change in reclassification (change in how you
consider someone from a risk perspective)
• Calibration: How closely the predicted probabilities agree
with the actual outcome
• Clinical utility (or actionability?) – Will more women take tamoxifen?
– How should this impact screening in the era of changing screening
recommendations?
• Ongoing studies
Key Points
In the US - this has become very complicated….

INTERVENTIONS
What is actionable?
• Something that potentially could be acted upon
• It does not mean that it is acted upon
• It does not mean that such action benefits a patient
• Actionability = clinical utility
• Critically important that all this be studied
• More cost effective (for the testing) to do multigene
rather than serial testing
• Patients (and providers!) can get testing fatigue
• The same cancer can be seen with different genes
mutations
– Ovarian cancer in both BRCA1/2 and Lynch
– Uterine cancer in Lynch and Cowden
– Breast in Li-Fraumeni and BRCA1/2
• Isn’t more better?
Why do this?
• High penetrance and moderate penetrance genes
are on one panel
– Implications for counseling
– Keeping track of it all
– Don’t we recognize clinical syndromes?
• (And if we don’t – what does it mean?)
• Variants of uncertain significance
• Clinical utility: order tests you will act on
– At least actionability
Domchek et al, JCO 2013
Potential Issues
• Screening and prevention
– Need to understand risks and benefits
– What age to start screening?
– What screening?
– What age to have preventative surgery?
– What to do with “unexpected” high penetrance mutation
• When we find things we don’t expect, what should we do?
Clinical utility
• Therapeutics
– Prognosis: may impact administration of adjuvant
therapy
– Drug development/selection
– Will tumors with mutations in these other genes be
sensitive to specific types of drugs?

BRCA1 Management
• Genetic testing can be very useful to patients and their family members – Both the prevent and to treat cancer
• Genetic testing is continuously evolving
• BRCA1 and BRCA2 mutations are the most commonly found and we have reasonable data on how to manage
• New genetics tests are often less clear in terms of how to change patients care – and improve patient outcome
• Variants of unknown significance should NOT be managed as mutations
• In the face of rising prophylactic mastectomies, we need to emphasize to patients how mutations in these genes are different from those in BRCA1/2
