Abstract

than non-IBD CRC patients, but they survived about 3 years longer.Older age, male sex, smoking, and advanced CRC grade and stage were independently associated with shorter survival times.When propensity score matching was used to analyse outcomes, the survival times of CRC patients with and without IBD were not significantly different. 16Taken together, these results reveal that IBD patients tend to develop CRC at younger ages than non-IBD patients.However, no effect of IBD on patient survival has been consistently demonstrated.
