[Intraarterial chemotherapy via reservoir system for far-advanced bladder and prostate cancer]

A clinical study was performed on the efficacy of intraarterial chemotherapy using reservoir system for far-advanced urological malignancy. The reservoir system was indwelled in the femoral subcutaneous layer using Seldinger's method. Fifteen cases with inoperable complicated advanced bladder cancer and ten cases with postoperative local recurrent bladder cancer received intraarterial chemotherapy using the reservoir system. Then, 23 cases with local relapsed prostate cancer and two cases with endocrine-resistant prostate cancer received chemotherapy. The administered anti-cancerous agents were methotrexate, cis-platinum and adriamycin, and 5-FU or carboplatin were administered as maintenance therapy. The mean courses of chemotherapy were six for bladder cancer and four for prostate cancer. During stabilization of the local lesion, no distant deterioration was recognized. Overall clinical efficacy was as follows: PR:18 cases and NC:7 cases for bladder cancer; then, PR:11 cases and 14 cases for prostate cancer. The median duration of stabilization was as follows: 23 months for bladder cancer and 12 months for prostate cancer. Complications were fewer than with systemic chemotherapy.
