[A bladder cancer with complete remission after arterial infusion of anti-cancer agents (CDDP and THP) and balloon-catheter occlusion of the internal iliac artery: a case report].

The case was a 63-year-old male with the chief complaint of hematuria. A local doctor made the diagnosis of a bladder tumor (egg-sized) on the basis of the results of ultrasonography. CT-scan and cystoscopy. He was thus referred to our Department for treatment. Histopathological study of the biopsied tumor specimen revealed that the tumor was a squamous cell carcinoma. The bilateral internal iliac arteries were occluded for 48 hours, and 100 mg of CDDP and 40 mg of THP were arterially infused. After 7 days, hematuria disappeared, as did the tumor 5 weeks after treatment. No malignancy was noted from histological examination of a biopsy specimen obtained from the cured cancer region using a cystoscope. Since then, there was no recurrence for 12 months. Thus, this approach is thought to be an effective treatment for primary bladder cancer.
