title: Intraarterial chemotherapy and hyperthermia for pain control in patients with recurrent rectal cancer.
abstract: For the majority of patients with unresectable recurrence of rectal cancer, persistent pain is the most distressing problem. This brief study describes a method to control pain in 10 patients with unresectable rectal cancer confined to the pelvis after standard therapy failed. All of the patients had percutaneous placement of infusion catheters in both internal iliac arteries. A continuous intraarterial infusion of 800 mg/m2 of 5-fluorouracil per day was given for 7 days and 10 mg/m2 of mitomycin C was administered as a bolus injection on the seventh day only. Four patients also received whole body hyperthermia by way of a Erbotherm 434 mHz microwave generator on the second and fifth days of infusion. Relief of pain occurred in three of the six patients who received intraarterial chemotherapy only. All four patients who also received hyperthermia achieved prolonged pain relief when it was added. We have concluded that intraarterial chemotherapy may be beneficial in patients with uncontrolled pelvic pain due to recurrent rectal cancer. The addition of hyperthermia may augment the benefit.
