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 < 0.001), a more complete staging of primary tumour and metastases and were more frequently multidisciplinary team-assessed than the non-screening group (p < 0.001). In both groups, patients with endoscopically resected cancers were less completely staged and multidisciplinary team-assessed than patients with surgically resected cancers (p < 0.001). No statistically significant differences were observed between the screening and non-screening groups in the...
