    Abstract:
    The importance of patient characteristics to long term survival in colorectal carcinoma is the subject of much debate. The importance of female gender as an advantagous factor in prognosis is difficult to determine. A retrospective study based on data from 1050 patients resected for colorectal carcinoma was carried out. A complete follow-up and survival data were available. Categorical variables such as age, sex, tumor stage and location, perioperative blood transfusions, and postoperative complications were used. Standard univariate and multivariate descriptive analysis was applied. In addition to tumor staging patients' sex was a strong significant factor on prognosis. When analysed independently of tumor location, blood transfusions, and severe complications, sex was revealed to be a statistically significant independent prognostic factor in longterm survival. The 5-year survival rate for men was 43.5 % and 54.7 % for women. When the observed survival was compared with sex related life expectancy of a representive population, similar differences of survival were seen for both sexes.
