COMBINED TREATMENT OF RADIOFREQUENCY CAPACITIVE HYPERTHERMIA FOR UROLOGICAL MALIGNANCIES

During the period from April 1984 to July 1993, we investigated the cl inical efficacy of local hyperthermia used to treat 110 patients with urological malignancies. We investigated the long-term outcome of 40 ( 36.4%) responders who exhibited an immediate, partial or better respon se to the therapy. The one-year survival rate was 75% for retroperiton eal tumor, 65% for bladder cancer, 33% for each of renal cell carcinom a and prostatic cancer and 29% for renal pelvic and ureteral cancer. T he 5-year survival rate was 48% for bladder cancer, 29% for renal pelv ic and ureteral cancer, 25% for retroperitoneal tumor, and 0% for rena l cell carcinoma and prostatic cancer. Subsidence of intolerable pain caused by cancer invasion was achieved in 29 of 42 patients (69.0%), i ndicating an improvement in patient's quality of life through pain rel ief.
