Improvementof results in treatment of colorectal cancer remains a major challenge due toits increasing worldwide prevalence. Several studies have demonstrated the qualityof surgical treatment as one of the most important prognostic factors, assessedby parameters such as operative mortality, sphincter preservation, local recurrenceand survival rates. The aim of this study is to present the long term resultsof Coloproctology Group of Department of Surgery of Hospital Municipal SãoJosé, in Joinville, Brazil, as well as its quality analysis accordingto the accepted standards from literature. A prospective analysis of a consecutiveseries of 97 colorectal cancer patients operated for curative purpose was undertaken,with a mean follow up of 80,8 months. Operative mortality occurred in six patients(6,1%), local recurrence for recatl and colon cancer in six (12,5%) and four(9,7%) patients, respectively, and abdominoperineal resection was performedin 14 cases (27%) for rectal cancer. Mean overall survival was 48,9 months.Five-year overall oncological survival (n=63) was 52%, including 89% for stage1,70% for stage 2 and 20% for stage 3 patients. We conclude that the results obtainedare acceptable for literature standards, but some specific parameters need tobe improved.
