Low referral rate for genetic testing in racially and ethnically diverse patients despite universal colorectal cancer screening
Clinical Gastroenterology and Hepatology Aug 23, 2018
Muller C, et al. - A retrospective analysis of colorectal tumors tested from 2012 through 2016 at 4 academic centers was performed to compare rates and outcomes of testing all tumor samples (universal testing) collected from a racially and ethnically diverse population for features of Lynch syndrome as well as evaluated rates of tumor testing, recommendations for genetic evaluation, rates of attending a genetic evaluation, and performance of germline testing overall and by race/ethnicity. The findings suggested that minority patients were less likely to be recommended for genetic evaluation or to undergo germline testing for Lynch syndrome in spite of similar rates of colorectal tumor analysis. It was noted that improvements in institutional practices in follow up after tumor testing could reduce barriers to diagnosis of Lynch diagnosis in minorities.
