Abstract
OBJECTIVE
Weekly administration of paclitaxel plus carboplatin is hypothesized to be an effective second-line treatment for advanced transitional cell cancer after failure of platinum-based regimen. In this phase 2 trial, we tested this hypothesis.
PATIENTS AND METHODS
Patients with advanced transitional cell cancer who showed evidence of progressive or recurrent disease after methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) therapy were eligible for this study. Weekly paclitaxel (80mg/m(2)) and carboplatin (AUC 2) were administered on days 1, 8, 15, 22, 29, and 36; the cycle was repeated every 7 wk until disease progression or intolerable toxicity (maximum 18 doses).
RESULTS
Thirty-five patients entered this study. Among the 31 patients who were assessable, 10 had an objective response (overall response rate: 32.3%, 95% confidence interval, 15.8-48.7%). The median progression-free survival (PFS) and median survival times were 3.7 and 7.9 mo, respectively. Among the 22 patients who received prior MVAC therapy for metastatic disease, 36% had an objective response; their median PFS and median survival times were 4.3 and 7.9 mo, respectively; neither survival time significantly differed from the survival time of those who received prior MVAC as adjuvant setting. Toxicities were mild except one toxic death due to neutropenic sepsis.
CONCLUSIONS
Weekly paclitaxel plus carboplatin was a manageable, active second-line treatment for advanced transitional cell cancer after failure of platinum-based therapy.
