[Intraarterial DDP and angiotensin II infusion chemotherapy]

Twenty-four patients, each with advanced bladder cancer (BC) or brain tumor (BT), were treated by intraarterial infusion of angiotensin II in combination with DDP as the main drug together with other anticancer drugs. As for the frequency of treatment by the intraarterial therapy, only one course was given in 15 cases, two courses in 9 (BC), one course in 21 cases, and two courses in 3 (BT). CR was obtained in ten of 24 evaluable patients with BC and PR in eleven. Of 20 evaluable patients with BT, 3CRs and 7PRs were attained. The selective enhancement of tumoral blood flow induced by regionally infused angiotensin II was observed using continuous intraarterial infusion of krypton-81 m.
