[Pelvic lymph node metastasis from bladder cancer markedly responsive to methotrexate vinblastine doxorubicin and cisplatin (M-VAC) therapy followed by radiotherapy: a case report]

Abstract

We report a case of bladder cancer with pelvic lymph node metastasis effectively treated by chemotherapy followed by radiotherapy. The patient was a 65-year-old man who had undergone radical cystectomy. Histological findings showed urothelial carcinoma, G3 > G2, pT1b. After 31 months, computerized tomography (CT) revealed a bulky tumor (7.0 x 5.6 cm) along the left pelvic wall, indicating pelvic lymph node metastasis. Five courses of chemotherapy consisting of M-VAC (methotrexate, vinblastine, doxorubicin and cisplatin) was performed. The size of the tumor was reduced to 1.5 x 1.0 cm. Then, external beam radiotherapy (50 Gy) was added to the residual tumor. He has been alive with no evidence of disease progression for 31 months since the radiotherapy.
