Influence of race on tolerance of platinum-based chemotherapy and clinical outcomes in women with advanced and recurrent cervical cancer: a pooled analysis of 3 Gynecologic Oncology Group studies.

OBJECTIVE: This study was undertaken to compare toxicity and outcomes from cisplatin-based combination chemotherapy for black and white women with advanced /recurrent cervical cancer. STUDY DESIGN: Frequencies of grade 3 and 4 toxicities, response, and survival were compared by race using data from 3 Gynecologic Oncology Group studies. RESULTS: Black women experienced significantly less grade 3 and 4 neutropenia (63% vs 82%), leukopenia (58% vs 79%), thrombocytopenia (10% vs 23%), and adverse events of any nature (84% vs 93%) compared with white women. Black patients were not at increased risk of disease progression (adjusted relative risk, 1.11; 95% confidence interval, 0.88-1.38; P = .382) or death (adjusted relative risk, 1.02; 95% confidence interval, 0.82-1.26; P = .893). CONCLUSION: Cisplatin-based chemotherapy delivered in a protocol setting for advanced/recurrent carcinoma of the cervix appears better tolerated by black women.
