The use of intraoperative radiotherapy and external beam therapy in the management of desmoid tumors.

Desmoid tumors are rare nonencapsulated benign lesions that invade the musculoaponeurotic tissues of the body. Such tumors infiltrate insidiously, and attempts to remove them frequently fail, usually leaving residual tumor. The use of adjuvant radiotherapy to decrease the recurrence rate in partially resected extra-abdominal desmoids has been reported by several authors. The role of irradiation in the management of desmoid tumors is illustrated in a case that combined surgery, intraoperative radiotherapy, and postoperative external beam radiotherapy in the management of this lesion.

Intraoperative radiotherapy for patients with carcinoma of the pancreas. The Howard University Hospital experience, 1978-1986.

During the period from 1978 to 1986, 106 patients were diagnosed with carcinoma of the pancreas; 30 of these patients were excluded from this study. Of the remaining 76 patients, 40 did not receive intraoperative radiotherapy (IORT) and were used as the nonrandomized control group for the 36 patients who did receive IORT after histologic confirmation of carcinoma of the pancreas. The records of 35 patients were available for review. The group receiving IORT ranged in ages from 43 to 89 years (20 males and 15 females). Seventeen patients had distant metastatic disease. The primary was located in the head of the pancreas in 32 and the body in three. No patient in this group had a curative resection. All patients were treated by a combination of biliary and gastric bypass prior to or concurrent with IORT. IORT was begun only after obtaining a histologic diagnosis and prior to the completion of any anastomosis. Necrotizing pancreatitis occurred in the treated group. There was no statistically significant difference in the survival of the nonrandomized control and treated groups.
