Seventy‐nine patients with histopathologically verified unresectable or locally recurrent rectal cancer were nonrandomly allocated to radiotherapy or regional intra‐arterial infusion of 5‐Fluorouracil (5‐FU). Fifteen patients with unresectable and 32 with locally recurrent rectal cancer were subjected to radiotherapy. The absorbed dose was 30 Gy in patients with an unresectable tumor and 45 Gy in patients with locally recurrent rectal cancer. Six patients with unresectable and 26 with locally recurrent rectal cancer received bilateral internal iliac artery infusion of 5‐FU in a median dose of 7.5 g. There was no difference in survival between the two methods of treatment. Resection of an initially unresectable tumor could be performed in 5 of 21 patients (4 after radiotherapy and 1 after chemotherapy). All except eight patients had pelvic or perineal pain before treatment. Forty of 43 (93%) patients reported pain relief after radiotherapy and 21 of 28 (75%) after infusion therapy. Ten nonresponders were subjected to alternative treatment (three to intra‐arterial infusion and seven to radiotherapy). Five of these ten patients reported complete pain relief and five partial pain relief. After radiotherapy, no significant side effects or complications were observed. The infusion chemotherapy was the cause of death in one patient. In summary, similar palliation was achieved with bilateral iliac artery 5‐FU‐infusion and radiotherapy. Owing to the complications registered with infusion therapy, radiotherapy must be considered the treatment of choice for these patients. Patients who do not respond to radiotherapy or suffer recurrence of pelvic and perineal pain may receive further palliation from intra‐arterial infusion. Cancer 58:336–340, 1986.
