Combined treatment of invasive bladder cancer by intra-arterial infusion chemotherapy of cisplatin with or without other anticancer agents and concurrent radiotherapy--initial response and side effects]

Fourteen patients with invasive bladder cancer were treated by bilateral internal iliac artery infusion of cisplatin, with or without other anticancer agents, and concurrent radiotherapy. Angiotensin II was simultaneously infused in 10 cases. Of the 14 patients, complete response and partial response were achieved in 9 (64%) and 3, respectively. Hematuria was controlled in all 8 patients, and pain was relieved in 3 of 4 patients. Side effects were observed in 8 patients: appetite loss in 8, nausea and/or vomiting in 7, and leukocytopenia in 6 patients, in 3 of whom radiotherapy had to be intermittent because of severe leukocytopenia (less than 2000/mm3). However, restoration of leukocytopenia occurred one week later. Thus, intra-arterial anticancer agents including cisplatin together with concurrent radiation may be one of the most effective therapies for invasive bladder cancer.
