Preliminary results of concurrent methotrexate, cisplatin and radiation treatment for locally advanced urothelial cancers.
Ten patients with invasive bladder cancer and one with locally advanced renal pelvic cancer were treated with concurrent methotrexate, cisplatin and radiotherapy. Methotrexate 30 mg/m2 was administered intravenously on the day of the initiation of radiotherapy and cisplatin 70 mg/m2 on the second day. The number of chemotherapy cycles delivered was 1 in 7 patients and 2 in 4. The median dose of radiation was 50 Gy. Of 11 patients, 7 (64%) achieved a partial response and 4 had no change in disease. The median duration of response was 16 months for patients with a partial response. Six patients with a partial response (55%) are alive for a median of 22.5 months and 2 of 4 with no change are alive for 4 and 15 months, respectively. Leukopenia less than 3000 cell/mm3 was observed in 4 (36%) and thrombocytopenia less than 100,000 cells/mm3 in 3 (27%). Local control could be achieved safely with concurrent methotrexate, cisplatin and radiation therapy in patients with locally advanced urothelial cancer who were unsuitable for surgery.
