In the period 01.01.1991-12.31.1996, 523 operations due to rectal carcinoma were performed on the First Surgical Clinic, the Third Department for Colorectal Surgery. Most common localization of tumor was in the distal third of the rectum 65.2%. In the middle third, there were 28.9% and in the upper, intraperitoneal third 5.9%. We performed 286 low anterior stapled resections, 93 anterior resections with hand-sewn anastomosis and 144 Abdominoperineal excisions of rectum (Miles procedure). Pathohistological examination revealed adenocarcinoma in all cases. In this study we analyzed local recurrence and five-year survival after long-term follow-up in the group where Miles procedure was carried out as a potentially curative procedure (except 4.9% cased with Dukes D stage). There were 74.3% males and 23.7% females median age 59.2 years. According to Dukes classification there were 4.9% in stage A, 47.2% in stage B, 43.1% stage C, and 4.9% stage D. There were 4(2.7%) postoperative deaths. Recurrence of the disease was registered in 44 (30.5%) patients. Local recurrence alone was found in 14 (9.7%) patients, while distant spread was registered in 30 (20.8%) patients. At present, the median follow-up is at 72.9 months. Analysis by the Kaplan-Meier's test shows cumulative survival of 61%, and disease free survival of 63.4% at 60 months of the follow-up. Dukes C is associated with a very poor prognosis; survival after 60 months of follow up shows cumulative Survival of 0.35 while Dukes B has far better prognosis (0.86). Analysis of disease free survival by Dukes stage shows that Dukes C has the worst prognosis (disease free survival 0.36 after 60 months), while stage B has much better prognosis (0.84). Local recurrence analysis by the Kaplan-Meier's test shows disease free survival of 84.9% at 60 months of follow-up. Analysis of local recurrence by Dukes stage shows 1.00% disease free survival for cases in stage A, 0.94 for Dukes B and 0.66 for Dukes C, while overall comparison between groups regarding local recurrence using the Wilcoxon (Gehan) statistic shows statistically significant difference (p-0.005). There is no statistical difference between Dukes A and Dukes B cases in distribution of local recurrence.
