[A case of lung metastases of bladder cancer in which thoracotomy was performed following M-VAC therapy].

A case of lung metastases of bladder cancer in which thoracotomy was performed following M-VAC is presented. A fifty-nine-year-old man underwent radical cystectomy and ileal conduit diversion for bladder cancer. Pathological diagnosis was TCC greater than AC much greater than SCC. After nine months, he was admitted because of lung metastases. Three courses of M-VAC therapy brought partial remission. A thoracotomy was performed on residual lung metastasis. Pathological diagnosis was AC much greater than TCC greater than SCC. Because M-VAC therapy has limited antitumor activity against mixed histological bladder cancer, we recommend not only M-VAC therapy but also surgical resection for the metastatic tumor the primary site of which has nontransitional components.
