title: Vinblastine and methotrexate for advanced bladder cancer.
abstract: Fifty-seven patients with advanced measurable urothelial tract cancer, 52 of whom had an adequate trial, were treated weekly with 3 to 4 mg. per m.2 vinblastine and 30 to 40 mg. per m.2 methotrexate. Of 3 patients with unidimensional parameters 2 showed improvement lasting 16 and 27 months, which was documented by serial cystoscopic examinations. An additional 2 patients had measurable disease that could have been encompassed in a preoperative radiotherapy field. Both patients are free of disease at more than 12 and 14 months, respectively. Of the 47 patients with bidimensionally measurable parameters 19 (40 per cent) achieved a complete or partial remission lasting a median of 8 months, with a range of 1 to 24 months. Of 25 patients with intra-abdominal or pelvic disease 7 achieved a complete or partial remission and 5 also had a minor remission. Of note, 18 of 38 patients who had received no prior chemotherapy achieved a remission versus 1 of 9 who had been treated previously (p equals 0.06). Responders frequently obtained another remission with subsequent chemotherapy (4 of 9 versus 0 of 16, p equals 0.03). Responders lived 14 months versus 8 months for nonresponders (p equals 0.02). Four responders had brain metastases compared to none of 28 nonresponders. The combination of vinblastine and methotrexate is a well tolerated, effective outpatient regimen for patients with urothelial tract cancers.
