Clinical features of colorectal mucinous and poorly differentiated adenocarcinomas; study concept of a propensity score analysis in a pooled data of 5530 patients

Abstract

The prognostic relevance of the mucinous subtype of colorectal cancer is still controversially discussed. We designed a large-scale cohort study with a propensity score matching to evaluate the impact of mucinous subtype on postoperative survival, recurrent patterns and chemo-sensitivity in patients with colorectal cancer using the integrated database of three phase III clinical trials. We introduce a study concept and present preliminary results of an overview of the total individual patients' data here.
