Methotrexate in the treatment of metastatic and recurrent primary transitional cell carcinoma.

Results in a series of 60 patients with recurrent or metastatic transitional cell carcinoma of the bladder confirm that methotrexate is active as a single agent. Over-all, 43 per cent of the patients with measurable metastases and 28 per cent with recurrent primary tumors responded for an average of 6 months. Response rates in both groups were influenced by the stage of the primary tumor.
