[A case of advanced bladder cancer successfully treated with intraarterial chemotherapy]

A 79-year-old Japanese male came to our hospital with complaints of protraction and macroscopic total hematuria. The medical imaging methods revealed a large papillary tumor in the left lateral wall of the bladder with the staging of T3N0M0. The pathological diagnosis was transitional cell carcinoma, G3. He received intraarterial chemotherapy with CDDP, ADM and MTX, which was called IA-MAC regimen. After two IA-MAC, no medical imaging method could reveal the tumor. The biopsied specimen, which was taken using the transurethral resection of the bladder mucosa, demonstrated no malignant cells. The new chemotherapeutic regimen "IA-MAC" is useful for the treatment of localized advanced bladder cancer in clinical use and enables one to preserve the organ.
