Adequacy of Chemotherapy Dose Intensity Among African-American Women with HER-2/neu-Positive Breast Cancer
Abstract
The purpose of this study is to investigate the possibility that systematic differences in the quality of adjuvant chemotherapy given to African-American and Caucasian women account for the poorer outcome in African-American women. We will determine the impact of these differences on outcome, particularly in patients whose tumors overexpress HER-2/neu (in whom chemotherapy dose is particularly important) . The analysis described in this report includes 489 subjects (109 African-American and 380 non-Hispanic Caucasian) who received adjuvant chemotherapy between 1985 - 1995 in two geographical locations. Chemotherapy dose proportion (actual/predicted doses) and dose intensity were determined for each drug and for the regimen. Using multivariate regression models, we have demonstrated that African- American ethnicity is an independent predictor of lower dose proportion and dose intensity (correcting for sociodemographic, tumor characteristics, and treatment course).
