“…Location could also be another risk factor to be taken into account. In this study as well as others which have been published in recent years [Brenner et al[28], Samadder et al[29] and Richter et al[30], a proximal location or right-sided colon seem to be a risk factor when developing an IC; similar to our study in which a proximal location was significantly more frequent than distal]. These locations would benefit from further targeted research.…”

AIMTo assess proportions, related conditions and survival of interval cancer (IC).METHODSThe programme has a linkage with different clinical databases and cancer registers to allow suitable evaluation. This evaluation involves the detection of ICs after a negative faecal inmunochemical test (FIT), interval cancer FIT (IC-FIT) prior to a subsequent invitation, and the detection of ICs after a positive FIT and confirmatory diagnosis without colorectal cancer (CRC) detected and before the following recommended colonoscopy, IC-colonoscopy. We conducted a retrospective observational study analyzing from January 2009 to December 2015 1193602 invited people onto the Programme (participation rate of 68.6%).RESULTSTwo thousand five hundred and eighteen cancers were diagnosed through the programme, 18 cases of IC-colonoscopy were found before the recommended follow-up (43542 colonoscopies performed) and 186 IC-FIT were identified before the following invitation of the 769200 negative FITs. There was no statistically significant relation between the predictor variables of ICs with sex, age and deprivation index, but there was relation between location and stage. Additionally, it was observed that there was less risk when the location was distal rather than proximal (OR = 0.28, 95%CI: 0.20-0.40, P < 0.0001), with no statistical significance when the location was in the rectum as opposed to proximal. When comparing the screen-detected cancers (SCs) with ICs, significant differences in survival were found (P < 0.001); being the 5-years survival for SCs 91.6% and IC-FIT 77.8%.CONCLUSIONThese findings in a Population Based CRC Screening Programme indicate the need of population-based studies that continue analyzing related factors to improve their detection and reducing harm.

“…Taken together, the literature data discussed above [18][19][20][21][22][23][26][27][28][29][30][31][32][33][34][35] suggest that our findings may contribute to addressing the issue of interval CRCs due to missed lesions. This hypothesis deserves to be tested in future studies.…”

“…The majority (36-44%) of interval cancers are found in the right colon [29][30][31]; and only a minority (19.5-28%) in the transverse colon (flexures included) [29][30][31]. Interval cancers are also smaller than sporadic or prevalent cancers [29,32].…”

“…Another recent area of interest is the observation that the majority of interval cancers are right-sided[9] possibly from missed right-sided sessile serrated adenomas (SSAs)[10]. Through the microsatellite instability pathway, such polyps have been shown to carry a significant risk of progression to malignant change[11].…”

AIMTo perform meta-analysis of the use of Endocuff during average risk screening colonoscopy.METHODSScopus, Cochrane databases, MEDLINE/PubMed, and CINAHL were searched in April 2016. Abstracts from Digestive Disease Week, United European Gastroenterology, and the American College of Gastroenterology meeting were also searched from 2004-2015. Studies comparing EC-assisted colonoscopy (EAC) to standard colonoscopy, for any indication, were included in the analysis. The analysis was conducted by using the Mantel-Haenszel or DerSimonian and Laird models with the odds ratio (OR) to assess adenoma detection, cecal intubation rate, and complications performed.RESULTSNine studies (n = 5624 patients) were included in the analysis. Compared to standard colonoscopy, procedures performed with EC had higher frequencies for adenoma (OR = 1.49, 95%CI: 1.23-1.80; P = 0.03), and sessile serrated adenomas detection (OR = 2.34 95%CI: 1.63-3.36; P < 0.001). There was no significant difference in cecal intubation rates between the EAC group and standard colonoscopy (OR = 1.26, 95%CI: 0.70-2.27, I2 = 0%; P = 0.44). EAC was associated with a higher risk of complications, most commonly being superficial mucosal injury without higher frequency for perforation.CONCLUSIONThe use of an EC on colonoscopy appears to improve pre-cancerous polyp detection without any difference in cecal intubation rates compared to standard colonoscopy.
