title: Paclitaxel and carboplatin in patients with metastatic transitional cell cancer of the urinary tract.
abstract: OBJECTIVE
  The combination of methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) is currently considered the most effective chemotherapy for metastatic transitional cell cancer (TCC) of the urinary tract, but because of its considerable toxicity, alternative regimens appear very interesting. We evaluated the efficacy and toxicity of a combination of paclitaxel and carboplatin as first-line therapy for metastatic TCC.
  
  
  METHODS
  Thirty-two patients (8 women, 24 men; mean age 67.03 years, range 50 to 79) with metastatic TCC of the bladder or upper urinary tract were included in the study. Paclitaxel (175 mg/m2) was given as a 3-hour intravenous infusion, carboplatin was dosed to an area under the plasma concentration curve of 5 mg/m/min calculated according to the Calvert formula [(creatinine clearance + 25) x 5] as a 30-minute intravenous infusion immediately after paclitaxel. Response evaluation was performed after every 2 cycles and additional therapy depended on response. The maximum number of cycles was 6.
  
  
  RESULTS
  With a mean follow-up of 13.1 months (range 2 to 28), 23 of 32 patients responded to treatment (response rate 71.9%), with 31.3% complete remission (CR) (10 of 32) and 40.6% partial remission (PR) (13 of 32). Four patients (12.5%) had stable disease, and 5 patients (15.6%) showed progression. These results compare well with the outcome after MVAC. Toxicity was mainly characterized by neurotoxicity grade 3 and 4 in 9.4%, grade 3 and 4 leukopenia in 37.5%, and grade 3 thrombocytopenia in 3.1% of the patients. No nephrotoxicity was observed, but all patients developed alopecia. Time to progression after CR was a mean of 7.0 months (range 4 to 13) and after PR a mean of 5.9 months (range 2 to 9).
  
  
  CONCLUSIONS
  Paclitaxel/carboplatin is an effective therapy for metastatic TCC, with low toxicity.
