To determine if pre-operative combined chemoradiation therapy increase sphincter preservation in the treatment of low-lying rectal cancer, 15 patients were treated with pre-operative chemoradiation: 5FU plus mitomycin C plus 4500-5000 Rad concurrent external beam radiotherapy between Jan 1997 and Jan 1999. There were 10 men and 5 women (Mean age: 49 y) with the diagnosis of invasive resectable primary adenocarcinoma of distal rectum limited to pelvis. Median tumor distance from anal verge was 3.3 cm (Range 0-5 cm) and half of the patients were absolute candidate for abdominoperineal resection. After 4-6 weeks, all patients were undergone proctectomy and eventually sphincter preservation surgery was done on 9 patients with colonal anastomosis. Function of sphincter was excellent in 6 of them (66%) and good in 3 patients (33%). There was no case of incontinence. Complications of surgery were minimal: One case of stricture (10%) and one case of partial rupture of anastomosis (10%). Complete pathologic response was achieved on one patient (6.6%) and combined pre-operative chemoradiation has changed the plane of surgery from abdominoperineal resection to sphincter saving in 69.2% of patients.
