SAN FRANCISCO, May 31, 2019 /PRNewswire/ — Researchers from Invitae (NYSE: NVTA), a leading medical genetics company, will present data that underscore the clinical utility of comprehensive genetic information for patients with breast, colorectal, prostate and pancreatic cancer to inform treatment decisions. Among the data, researchers will discuss findings showing that multigene germline genetic testing for breast cancer patients impacts patient outcomes and informs surgical strategy, precision medicine treatment and clinical trial eligibility.
The studies will be presented at the American Society for Clinical Oncology (ASCO) Annual Meeting in Chicago, which starts today.
A study of breast cancer patients conducted with researchers from the TME Breast Care Network, a network of more than 300 leading breast cancer physicians, evaluated germline genetic testing for 912 breast cancer patients, approximately half of whom met widely accepted clinical guidelines for testing and half of whom did not. Pathogenic/likely pathogenic (P/LP) germline variants were found in 8.65% of patients (9.39% of patients who met guidelines and 7.9% of patients who did not meet guidelines, a statistically insignificant difference). Among patients with P/LP germline variants, 85% had variants in cancer-risk genes with established management recommendations and 80% had variants that made them eligible for clinical trials and/or precision medicine-based cancer treatments, such as PARP inhibitors. In 62% of patients with P/LP germline mutations, their clinicians reported the findings impacted their patients’ outcomes.
“This research adds to the body of evidence validating the importance of comprehensive germline genetic testing in cancer for identifying precision medicine therapies and clinical trials that can improve patient outcomes,” said Robert Nussbaum, M.D., chief medical officer of Invitae. “Previous research has shown that current testing guidelines are insensitive and deny too many patients with clinically meaningful genetic variants from being tested. Broad use of multigene genetic testing for cancer patients has the potential to meaningfully improve cancer care for patients across a wide variety of cancers.”
Another study presented at the meeting examined testing in colorectal cancer using multigene panels, and suggests one in five patients referred for genetic testing have clinically actionable germline variants, nearly half of which remain undetected when only a narrowly defined panel of the five mismatch repair genes are tested. Furthermore, some of these variants were in genes associated with known precision therapeutic implications or clinical trial eligibility, as well as established clinical management guidelines.
Germline testing was performed on 9,000 patients with colorectal cancer and clinically significant variants were identified in 21% (2,101) of patients. When only a limited genetic panel was used, 9% of patients had a pathogenic finding, which increased to 15% when 19 guidelines-based colorectal cancer genes were assessed. Using a comprehensive multigene panel, P/LP variants in genes with known precision therapy implications were detected in 14% (1,408) of patients, and 17% (1,670) had P/LP variants associated with established clinical management guidelines. These data add to the evidence supporting the value of comprehensive germline genetic testing for colorectal cancer patients to identify candidates for precision medical treatments and provide clinical guidance to at-risk family members.
Invitae has also collaborated with numerous clinicians and scientists outside of the company to carry out additional research being presented at ASCO that highlight the depth and impact of innovation at Invitae. The research presentations further underscore our commitment to advancing understanding of the importance of germline genetic testing in oncology and showing its clinical utility in improving patient care.
