Real world data in colorectal cancer: A retrospective analysis of overall survival in metastatic colorectal cancer patients between 2011-2015 treated in Spain, preliminary results (RWD-ACROSS study)

Abstract

Introduction: Colorectal cancer is a global problem due the incidence and prevalence. Clinical trials do not represent treatment of real life population effectiveness, so real world data trials are needed. Aim: We present preliminary results based on a registry for Spanish metastatic colorectal cancer (mCRC) patients.Methods: Cohort study including 4 hospitals in Spain. Inclusion criteria: Aged≥18 years(y), histological confirmation mCRC, at least 1 cycle of chemotherapy(CT) administered, mCRC diagnosed between 01/2011-12/2015. Overall survival(OS) was calculated from time of mCRC diagnosis to death or date of last contact. Kaplan-Meier curves were used to estimate median survival and survival rates. The study was approved by Ethics Committees.
