CHICAGO, June 4, 2016 /PRNewswire/ -- Two new studies co-authored by researchers from John Theurer Cancer Center (JTCC) at Hackensack University Medical Center and discussed at the American Society of Clinical Oncology (ASCO) annual meeting demonstrate the potentially substantial therapeutic benefit of genomic profiling in serious, life-threatening cancers.
The first study abstract (#e20616), "Genomic Profiling of Non-Small Cell Lung Cancer in the Community Setting," led by Martin Gutierrez, M.D., Director, Drug Discovery and Phase I Unit, John Theurer Cancer Center at Hackensack University Medical Center, demonstrates that genotyping in patients with advanced non-small cell lung cancer (NSCLC) identifies mutations likely to respond to targeted therapies. Most patients with NSCLC present with advanced stages of the disease (stage IIIB or IV). Up to 11 mutations have been reported, seven of which are now recommended for testing in routine practice.
Researchers studied retrospectively 634 patients with NSCLC from the COTA (Cancer Outcomes Tracking & Analysis) database and identified patterns of testing and treatment in the "real-world" clinical setting. The investigators determined that genotyping for two most common relevant mutations i.e., epidermal growth factor receptor (EGFR), a gene involved in cell growth and multiplication; and anaplastic lymphoma kinase (ALK), which contributes to cell proliferation and tumor survival, remain below recommended guidelines. Researchers concluded most patients are under-genotyped for all seven NSCLC treatable mutations.
"The benefit of targeted therapies has been demonstrated in large randomized clinical trials with not only better outcome including survival and less toxicity than standard chemotherapy. Evidently, efforts to support appropriate and timely testing must be encouraged in order to ultimately provide the best option for each of our patients," said Andre Goy, M.D., M.S., Chairman, John Theurer Cancer Center, and board member, COTA.
A second study (abstract #e18255) utilizing the COTA genomic database, "Early Economic Benefits of Gene Expression Profiling Using a 21-Gene Panel among Patients with Early Stage, Lymph Node Negative, Hormone Receptor Positive, HER2/neu Oncogene Negative Breast Cancer," was led by Stanley E. Waintraub, co-chief, Division of Breast Oncology, John Theurer Cancer Center, and Chief, Division of Hematology, Hackensack University Medical Center. Dr. Waintraub and colleagues assessed 227 breast cancer patients under 70 years of age; 68 percent underwent gene expression profiling (GEP).
The study demonstrates that GEP was able to identify a patient cohort showing positive long-term outcomes without need for adjuvant chemotherapy, resulting in significant cost savings, while maintaining a positive quality-adjusted life year (QALY), a measure of disease burden used to assess the value of medical interventions. Data revealed that adjuvant chemotherapy was utilized less in stage II patients with genomic profiled tumors, resulting in net savings of $11,494 per patient inclusive of the cost of the test. The GEP also identified a small group of high-risk patients with stage 1 disease who would likely benefit from chemotherapy, with a cost increase in that group of $4,505.
Researchers concluded that universal GEP testing of stage II or grade II/III lymph node negative breast cancers resulted in lower outpatient costs inclusive of the diagnostic test within the first six months of care. Among patients with stage I disease, GEP identified a small group of higher-risk patients who may derive clinical benefit from adjuvant chemotherapy who otherwise might not have been treated, with acceptable QALY ratios.
"Real-world confirmation of quality-adjusted life year is scant, and few studies focuses on the short-term costs that are critical in value-based payment reform," said Dr. Goy. "It comes down to adjusting appropriately our diagnostic and therapeutic approaches to optimize our patients' outcome. Smarter medicine is the answer to provide the best outcome with best value over time."

Developed by world-leading oncologists, Cancer Outcomes Tracking & Analysis (COTA) has developed the unique CNA (COTA Nodal Address) System to precisely classify cancer patients into meaningful clinical and prognostic cohorts. Using this sorting technique, COTA is able to account for the biologic variances of cancer, thus permitting more in-depth analyses of treatment variances. This enables doctors and health plans to improve patient care and move from fee-for-service to value-based reimbursement models. COTA arms providers, patients and payers with the actionable, real-time insights needed to improve clinical outcomes, while reducing the costs. Based in New York City, the Company's mission is to enable optimal care for every cancer patient. To learn more about COTA, call (866) 648-3833 or visit www.oncota.com.
