Age-Based Genetic Testing May Miss Most Inherited Variants in Cancer Patients
A study published in Cancer Discovery suggests that universal genetic testing for cancer patients, regardless of age, identifies significantly more inherited gene variants than current age-restricted protocols. Researchers argue that the standard age-50 cutoff for germline screening may be missing critical diagnostic information.
Why it matters
This research challenges current medical screening standards and could lead to more comprehensive cancer prevention and treatment strategies for older patients.
Bottom Line: Universal germline genetic testing of nearly 40,000 patients with solid tumors detected a substantial proportion of inherited gene variants that would have been missed by the standard germline testing approach that excludes those over age 50.
Journal in Which the Study was Published: Cancer Discovery , a journal of the American Association for Cancer Research (AACR) .
Authors: Zsofia K. Stadler, MD , and Luis A. Diaz, Jr., MD, FAACR are the two co-corresponding authors. At Memorial Sloan Kettering Cancer Center Stadler serves as the clinical director of the Clinical Genetics Service, and Diaz is the head of Solid Tumor Oncology.
