    We sought to determine whether age was significantly associated with efficacy and toxicity of weekly docetaxel in patients with metastatic androgen-independent prostate cancer (AIPC). Individual patient data were pooled from 2 phase II clinical trials of weekly docetaxel 36 mg/m2 for 6 of every 8 weeks in men with metastatic AIPC. Baseline characteristics and outcome measures of men ≥ 70 years of age (n = 52) were compared with patients < 70 of age (n = 34) using Pearson χ2 test for categoric variables, Mann-Whitney U test for continuous variables, and log-rank test of Kaplan-Meier estimates for time-dependent variable. Multivariate analysis was used to adjust for any imbalances in baseline characteristics. At baseline, older patients had a lower hemoglobin level (P = 0.05) and a higher serum prostate-specific antigen (PSA; P = 0.04). The PSA response rate was 47% (95% Cl, 33%-62%) in older patients and 40% (95% Cl, 23%-59%) in younger patients (P = 0.75). Similarly, measurable disease response rate (P = 0.43), time to progression (P = 0.28), and survival (P = 0.52) were not affected by age in both univariate and multivariate analyses. There was also no difference in overall hematologic and nonhematologic toxicity ≥ grade 2. This comparison of pooled individual patient data from 2 phase II studies of weekly docetaxel in AIPC did not reveal significant differences in efficacy or toxicity in men aged ≥ 70 years compared with younger patients. These findings are consistent with the hypothesis that docetaxel chemotherapy in patients with AIPC is equally well tolerated and effective across a wide range of ages.
