The clinical, laboratory, and pathologic data of 361 patients who had curative resections for colorectal cancers were collected and analyzed in a multiple stepwise regression model. In univariate analysis, among clinical factors, bowel obstruction and emergency surgery showed the most significant prognostic value (P = 0.002, P = 0.004, respectively). Vegetating growth, Astler-Coller stage of tumor, intramural spread, lymph node involvement, and synchronous liver metastases resulted in the pathologic variable significantly affecting the prognosis (P = 0.006, P less than 0.001, P = 0.036, P less than 0.001, P less than 0.001, respectively). In the multivariate analysis, stage was the predictive factor with the highest hazard ratio in conjunction with bowel obstruction (P less than 0.0001 in both cases). Processing data excluding stage ("multiparametric factor" itself), hepatic metastases, lymph node involvement, bowel obstruction, and intramural spread appeared as independent predictors of survival (P less than 0.0001, P less than 0.0001, P = 0.0004, P = 0.0316, respectively). Other variables, as biologic and molecular factors, should be more widely tested in order to assess their impact on prognosis.
