BACKGROUND The objective of this investigation was to assess whether preoperative carcinoembryonic antigen (CEA) level is an independent predictor of overall survival in rectal cancer patients. METHODS All patients (n=504) undergoing a resection for stage I-III rectal cancer at the Kantonsspital St Gallen were included into a database between 1991 and 2008. The impact of preoperative CEA level on overall survival was assessed using risk-adjusted Cox proportional hazard regression models and propensity score methods. RESULTS In risk-adjusted Cox proportional hazard regression analyses, preoperative CEA level (hazard ratio (HR): 1.98, 95% confidence interval (CI): 1.36-2.90, P<0.001), distance from anal verge (<5 cm: HR: 1.93, 95% CI: 1.11-3.37; P=0.039), older age (HR: 1.07, 95% CI: 1.05-1.09; P<0.001), lower body mass index (HR: 0.94, 95% CI: 0.89-0.98; P=0.006), advanced tumour stage (stage II HR: 1.41, 95% CI: 0.85-2.32; stage III HR: 2.08, 95% CI: 1.31-3.31; P=0.004), R 1 resection (HR: 5.65, 95% CI: 1.59-20.1; P=0.005) and chronic kidney disease (HR: 2.28, 95% CI: 1.03-5.04; P=0.049) were all predictors for poor overall survival. CONCLUSIONS This is one of the first investigations based on a large cohort of exclusively rectal cancer patients demonstrating that preoperative CEA level is a strong predictor of decreased overall survival. Preoperative CEA should be used as a prognostic factor in the preoperative assessment of rectal cancer patients.

D012044 Regression Analysis Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
