Diagnostic value of radiological staging and surveillance for T1 colorectal carcinomas: A multicenter cohort study.

Background: The role of radiological staging and surveillance imaging is under debate for T1 colorectal cancer (CRC) as the risk of distant metastases is low and imaging may lead to the detection of incidental findings.

Objective: The aim of this study was to evaluate the yield of radiological staging and surveillance imaging for T1 CRC.

Methods: In this retrospective multicenter cohort study, all patients of 10 Dutch hospitals with histologically proven T1 CRC who underwent radiological staging in the period 2000-2014 were included.

[The problems of professional competence in the complementary professional forensic medical expertise programs of advanced training and professional requalification].

This article reports the results of the analysis of the new tendencies and normatives of the working legislation in the field of additional professional education in the speciality of «forensic medical expertise» and the application of the competency-based approach to the training of specialists in the framework of professional requalification and advanced training programs. Special attention is given to the problems of organization of the educational process and the elaboration of additional training programs based on the competency approach to the training of specialists at the Department of Forensic Medicine and Law with the professor V.N.

Missed adenomas with behind-folds visualizing colonoscopy technologies compared with standard colonoscopy: a pooled analysis of 3 randomized back-to-back tandem colonoscopy studies.

Background And Aims: The Third Eye Retroscope, Full Spectrum Endoscope (FUSE), and EndoRings devices have been shown to reduce overall adenoma miss rates. We evaluated the characteristics of adenomas and patient subgroups for which these behind-folds visualizing technologies mostly reduce adenoma miss rates.

Methods: Data of 3 multicenter randomized trials (NCT01044732, NCT01549535, NCT01955122) were combined.

Measuring gaze patterns during colonoscopy: a useful tool to evaluate colon inspection?

Background And Objective: Considerable variation in adenoma detection has been shown between endoscopists, which may be explained by differences in colon inspection. Eye-tracking technology is an objective tool that detects differences in viewing patterns. We investigated the feasibility of eye-tracking technology during real-time, self-performed colonoscopies.

Prospective Dutch colorectal cancer cohort: an infrastructure for long-term observational, prognostic, predictive and (randomized) intervention research.

Background: Systematic evaluation and validation of new prognostic and predictive markers, technologies and interventions for colorectal cancer (CRC) is crucial for optimizing patients' outcomes. With only 5-15% of patients participating in clinical trials, generalizability of results is poor. Moreover, current trials often lack the capacity for post-hoc subgroup analyses.
