The outcomes from a Mayo Clinic study published in Oncotarget found value in having an established genomic tumor board, and using genomics for certain patients.
The experience of the Genomic Tumor Board has promoted an evolution in the practice according to Alan Bryce, M.D., a Mayo Clinic oncologist, and co-first author on the study.
“There is an emerging consensus to begin genomic analysis early in the treatment course due to many driver mutations presenting early in the disease course. This allows time for potential therapies in a clinically useful timeframe,” says Dr. Bryce.
Mayo researchers looked at initial results from their efforts in establishing the Mayo Clinic Genomic Tumor Board. The board brings together physicians, research scientists, cancer biologists, ethicists, pathologists, bioinformaticians and genetic counselors from Mayo Clinic campuses in Arizona, Florida, and Minnesota. This “A” team reviews and discusses each case, bringing their unique expertise to the table. Through consensus they conclude if findings are deemed actionable, lead to treatment recommendations, and are deemed informative.
According to Jan Egan, Ph.D., a Mayo Clinic research scientist and co-first author, the Genomic Tumor Board provided a translational platform to transform the practice.
“We brought together the unique perspectives of clinicians and laboratory scientists to drive treatment decisions and create patient focused research questions,” says Dr. Egan.
The Mayo Clinic Genomic Tumor Board engaged in patient case review to address limitations by considering genomic testing results, in addition to treatment options such as: surgery, ablation, radiation, new chemotherapy, or observation. Other benefits included facilitating collaboration between physicians and scientists to assist with target prioritization or consideration of alternate targets. It also provided a forum for teaching and consideration of alternative treatment options in complex cases. The Genomic Tumor Board contributed to the ongoing revolution of tumor genomic-based treatment in cancer, along with innovations in clinical trial design, technological innovations in big data management, and regulatory changes promoting data.
What are the barriers to delivery?
The study revealed these barriers to implementing genomics into cancer care:
Looking ahead, researchers identified the importance of rapidly sharing insights gained from successful treatment to other clinicians and investigators. In addition, cross-institutional databases linking genomic profiles and treatment outcomes are needed given the rarity of specific abnormality/tumor combinations. Lastly, cost of tumor sequencing should be compared to the cost of treating with unselected therapies or enrolling in non-biomarker based clinical trials.
“We demonstrated treatment decisions driven by tumor genomic analysis can lead to significant clinical benefit in a minority of patients,” says Dr. Bryce.
