The role of paclitaxel in the therapy of bladder cancer.
Although significant strides have been made in the development of effective chemotherapy for metastatic bladder cancer, those benefits have plateaued and prompted a search for new, active agents. The most active of a new generation of investigational agents is paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ). The only single-agent phase II trial to date, which used paclitaxel at a dose of 250 mg/m2 by 24-hour infusion every 3 weeks, resulted in a 42% response rate and a 27% complete response rate in previously untreated patients. With granulocyte colony-stimulating factor support, this therapy was well tolerated, with fewer than 10% of patients developing neurtropenic fever during therapy. Paclitaxel's potential as a radiation sensitizer and its relatively low renal excretion make it an attractive agent for use in patients with urothelial carcinoma. The goal of ongoing and planned clinical trials will be to (1) identify potential paclitaxel-containing combination regimens, (2) define the optimal dose and schedule of administration in patients with bladder cancer, and (3) define the activity of paclitaxel in previously treated patients.
