Screen detection is a survival predictor independent of pathological grade in colorectal cancer. A prospective cohort study

摘要

Introduction: Patients with screened detected colorectal cancer (CRC) have a better survival than patients referred with symptoms. This may be because of cancers being identified in a younger population and at an earlier stage. In this study, we assess whether screened detected CRC has an improved outcome after controlling for key pathological and patient factors known to influence prognosis.
