Summary
Brief summary (as posted)
The purpose of this study is to determine whether colorectal cancer diagnosed by screening (primary screening colonoscopy, colonoscopy after immunochemical based faecal occult blood test) has more favourable clinical-pathological characteristics than colorectal cancer diagnosed for symptoms. We aimed to compare these two groups of patients at the time of diagnosis and confirm the efficiency of the screening programme.
