Weekly docetaxel in elderly patients with prostate cancer: efficacy and toxicity in patients at least 70 years of age compared with patients younger than 70 years.


Journal Article

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/m(2) 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 c2 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% CI, 33%-62%) in older patients and 40% (95% CI, 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.
