Results of treatment of patients with local recurrence of colon cancer.

Abstract

Aim : to improve the results of treatment of patients with local recurrence of colon cancer and evaluate effectiveness of the combined treatment. Materials and methods . From 1997 to 2012 in SRCC 71 consecutive patients underwent combined surgery for local recurrence of colon cancer. Of these patients 38 (53.5%) had surgical treatment with intraoperative intraperitoneal chemotherapy. Sixty-five (91.5%) patients had locally advanced recurrent tumor. Localization of local recurrence in patients who underwent combined operations, was as follows: in the area of colonic anastomosis - in 11 (15.5%) patients; in the bed of the removed tumor - in 19 (26.8%); in the area of colostomy - in 10 cases (14.1%); in the stump of distal colon after obstructive procedures - in 31 (43.6%) patients. Mean operative time was 270 ± 45 minutes and mean blood loss - 430 ± 80 ml. Results . Postoperative complications were observed in 6 (9.8%) of 61 patients. There was no mortality. Sixty-four (90.1%) patients were followed-up, 34 (53.1%) patients of which are currently alive with no signs of the relapse of the disease. Effectiveness of intraperitoneal chemotherapy was evaluated. Repeated local recurrence occurred in 5 (14.3%) of the 35 followed-up patients who underwent intraperitoneal chemotherapy, and in 6 (20.7%) of the 29 followed-up patients who received surgery alone (p = 0.2). Distant metastases were found in 9 (25.7%) and in 5 patients (17.2%) patients, respectively (p = 0.17), and peritoneal carcinomatosis in 1 (2.9%) and 4 (13.8%) cases, respectively (p = 0.09). Disease-free 5-year survival rate in patients who received intraperitoneal chemotherapy was 57.1%, and in patients received only surgical treatment - 48.3% (p = 0.15).
