Utilization of Oncotype DX in an Inner City Population: Race or Place?

ABSTRACT: Oncotype DX, a 21-gene-array analysis, can guide chemotherapy treatment decisions for women with ER+ tumors. Of 225 ER+ women participating in a patient assistance trial, 23% underwent Oncotype DX testing: 31% of whites, 21% of blacks, and 14% of Hispanics (P = 0.04) were tested. Only 3 white women were treated at municipal hospitals and none was tested. 3% of women treated in municipal hospital as compared to 30% treated at tertiary referral centers were tested (P = 0.001). Within tertiary referral centers, there was no racial difference in testing: 32% of whites, 29% of blacks, and 19% of Hispanics (P = 0.25). Multivariate analysis (model c-statistic = 0.76; P < 0.0001) revealed that women who underwent testing were more likely to have stage 1B (RR = 1.70; 95% CI: 1.45-1.85) and to be tr
