Background: Patients with incompletely resected locally advanced and recurrent colon cancers have a dismal prognosis. Since 1981, 100 colon cancer patients have been treated with combination therapy including surgical resection, chemotherapy, and external plus intraoperative radiotherapy. Methods: A prospective computerized intraoperative radiation database identified patients for this retrospective review. Data collection included patient demographics, tumor and treatment variables, and morbidity, recurrence, and survival statistics. Results: The mean age was 55.2 years. Follow-up was available for all patients. Fifty-nine patients have died. Median follow-up of survivors was 70.5 months. Twenty-five patients with locally advanced colon cancer had a median survival of 38.2 months and a 5-year survival of 49%. Eleven of these patients are still free of disease. Seventy-three patients treated for recurrent colon carcinoma had a median survival of 33.3 months from the time of recurrence, with a 5-year survival of 24.7%. Twenty-one are alive without evidence of recurrence. The 38 patients with recurrent disease whose disease was completely resected had a 37.4% 5-year survival. Conclusions: A multimodality approach using en-bloc surgical resection with radiotherapy and chemotherapy affords some patients with locally advanced and recurrent colon cancer a chance for long-term survival.
