Screening vs. non-screening detected colorectal cancer: Differences in pre-therapeutic work up and treatment

ObjectivesTo compare preoperative staging, multidisciplinary team-assessment, and treatment in patients with screening detected and non-screening detected colorectal cancer.MethodsData on patient and tumour characteristics, staging, multidisciplinary team-assessment and treatment in patients with screening and non-screening detected colorectal cancer from 2008 to 2012 were collected from the Stockholm–Gotland screening register and the Swedish Colorectal Cancer Registry.ResultsThe screening group had a higher proportion of stage I disease (41 vs. 15%; p ConclusionsScreening detected cancer patients were staged and multidisciplinary team assessed more extensively than patients with non-screening detected cancers. Staging and multidisciplinary team assessment prior to endoscopic resection was less complete compared with surgical resection. Extensive surgical and (neo)adjuvant treatment was given in stage I disease. Participation in screening reduced the risk of emergency surgery for colorectal cancer.
