Total mesorectal excision for surgical treatment of rectal cancer

Background and Objectives: The aim of our study was to retrospectively eval uate the results of 2 groups of patients admitted and treated for rectal ca ncer. Methods: One hundred and fifty-one patients were available for evaluation. Eighty (group A) were radically operated with the standard technique; 71 (g roup B) underwent total mesorectal excision (TME). Groups were similar acco rding to demographics, staging, and pathological data. Mean follow-up was 7 3.5 months. Results: No operative mortality was observed. Complications were 15% in gro up A and 32% in group B. Local recurrence rates were 41.2% in group A and 1 2.6% in group B. Distant metastases occurred in 21.2% and 7.6%, respectivel y, in groups A and B. Cancer-related mortality was 62.5% in the non-TME gro up and 19.5% in the TME group. Overall 5-year survival rates were 32.4% in group A and 70.5% in group B. Disease-free survival rates were 25% in group A and 62.3% in group B. Conclusions: TME appears to lower the incidence of cancer-related mortality , with a higher incidence of postoperative complications. Further studies n eed to be done to assess the real benefits of TME in the surgical treatment of rectal cancer. (C) 2000 Wiley-Liss, Inc.
