[A case of primary urothelial carcinoma of the prostate responsive to MVAC intra-arterial chemotherapy: a case report].

A 70-year-old man visited a urological clinic on May 2008 complaining of dysuria and nocturia since 2 years prior. He was diagnosed as having gross benign prostatic hypertrophy, and was referred to a nearby hospital for transurethral resection of prostate (TURP). During TURP, a papillary tumor was found in the prostatic urethra on the left side and a biopsy was performed. A pathological examination revealed urothelial carcinoma G3. Cystoprostatectomy was planned, but the patient refused the procedure. Therefore, he underwent three courses of MVAC intra-arterial chemotherapy (methotrexate, vinblastin, doxorubicin, cisplatinum) at our hospital. After chemotherapy, no tumor was found in the prostatic urethra and a pathological report of repeat TUR showed no tumor. Currently, the patient is alive and there has been no evidence of recurrence for 1 year and 10 month.
