Abstract

PurposeTo investigate the effect of race on the efficacy and safety of standard chemotherapy doublet regimens in African American patients, we conducted a subgroup analysis of a phase III randomized trial.Patients and MethodsChemonaïve patients with a performance status of 0 or 1 and stage IIIB or IV non-small cell lung cancer were randomized to arm A: gemcitabine 1000 mg/m2 on days 1 and 8 plus carboplatin area under the curve 5.5 on day 1; arm B: the same schedule of gemcitabine plus paclitaxel 200 mg/m2 on day 1; or arm C: paclitaxel 225 mg/m2 on day 1 plus carboplatin area under the curve 6.0 on day 1. Cycles were repeated every 21 days up to 6. A site selection tool identified institutions with potential to recruit a minority population. Outcome and toxicity data of white and African American patients were compared.ResultsOf 1135 total patients, 972 were white (85.6%) and 138 were African American (12.2%). Median survival was 8.3 months for white patients (95% confidence interval [CI]: 7.7–9.3) and 9.1 months for African American patients (95% CI: 8.2–11.1). Response rates were 29.1 and 29.0%, respectively. Rates of grade 3 or 4 toxicities were comparable. Among African Americans, median survival was 7.2 months (95% CI: 5.1–10.1) for gemcitabine-carboplatin (n = 47), 10.5 months (95% CI: 7.1–15.4) for gemcitabine-paclitaxel (n = 42), and 10.2 months (95% CI: 8.5–13.2) for paclitaxel-carboplatin (n = 49).ConclusionWhites and African Americans had similar outcomes, although there was some variability in survival among African Americans across the three treatment groups.
