PURPOSE: Despite the encouraging results of chemotherapy in patients affected by incurable colorectal cancer (CRC), surgical resection of a primitive tumor is still a common approach worldwide. The identification of prognostic factors related to short survival (<6 months) may allow excluding from resective surgery those who may not benefit from it. METHODS: A retrospective analysis was performed of 15 variables in a population of 71 patients undergoing nonemergency palliative primary resections of incurable CRC, including patients' demographics and clinical/histopathological characteristics of the tumor. RESULTS: No variables were related to perioperative mortality (8.5% overall). A multivariate analysis revealed that older age (≥80 years) and metastasis to more than 25% of the lymph nodes were associated with survival (4 and 6 months, respectively). Mucoid adenocarcinoma therefore tends to be associated with the prognosis (P = 0.070). CONCLUSIONS: An elderly age tends to be a contraindication to an elective primary tumor resection in patients affected by incurable CRC. Massive lymph node involvement and mucoid adenocarcinoma should also be considered before planning major colonic surgery.
