- W2080147551 abstract "Limited information is available on predictors of postoperative mortality, morbidity, and long-term survival in patients with stage IV colorectal cancer.This study aimed to identify independent predictors of postoperative mortality and morbidity as well as independent predictors of long-term survival.This study was planned as a retrospective single-institution review.This study took place at the Department of Surgery, The Royal Brisbane and Women's Hospital, Australia, between 1984 and 2004.Prospectively collected data were extracted from the records of 1867 patients undergoing treatment for colorectal cancer. The outcomes for 379 patients undergoing surgical resection of their primary colon or rectal tumor in the presence of unresectable synchronous metastases were analyzed.Independent predictive factors for postoperative mortality and morbidity as well as long-term survival were assessed by use of logistic regression and Cox regression analysis.Thirty-five (9.2%) patients died in the postoperative period and morbidity was 48.3%. Median survival was 11 months. Thirty-day postoperative mortality was independently associated with medical complications (P < .001), emergency operations (P = .001), female sex (P = .002), and age (≥ 70; P = .007) on regression analysis. Elderly (≥ 70) patients with either advanced local disease or extrahepatic metastases were at a particularly high risk. Preoperative predictors of surgical morbidity included male sex (P = .028) and advanced local disease (P = .036). Preoperative predictors of medical complications included repeat operations (P < .001), elevated urea levels (P = .017), and emergency operations (P = .003). Independent factors associated with poor overall survival included medical complications (P < .001), nodal stage (N2) (P = .004), poor tumor differentiation (P = .006), and apical lymph node involvement (P = .042). A subgroup of patients with advanced nodal disease (N2) and a poor tumor differentiation had a significantly poorer prognosis.This study was limited by its retrospective nature.Elderly patients with advanced local disease or extrahepatic metastases are at high risk of 30-day postoperative mortality. Significant nodal disease and poor tumor differentiation are important predictors of long-term survival." @default.
