The impact of screening on the survival of colorectal cancer in Shanghai, China: a population based study.

ABSTRACT:

Background

Shanghai is one of the earliest cities in developing countries to introduce an organized colorectal screening program for its residents to fight against the rising disease burden of colorectal cancer (CRC). This study aims to investigate the impact of the Shanghai screening program implemented in 2013 on the survival rates of CRC patients.

Methods

We calculated up to 5-year survival rates for 18,592 CRC patients from a representative district of Shanghai during 2002-2016, using data from the Shanghai Cancer Registry. We performed joinpoint regressions to examine temporal changes in the trends of the CRC survival rates. We then conducted Kaplan-Meier and Cox proportional hazards modelling to study the association of the survival rates with screening behaviors of th
