Adenoma Detection Rates by Physicians and Subsequent Colorectal Cancer Risk.

Importance: Patients of physicians with higher adenoma detection rates (ADRs) during colonoscopy have lower colorectal cancer (CRC) risk after screening colonoscopy (ie, postcolonoscopy CRC). Among physicians with an ADR above the recommended threshold, it is unknown whether improving ADR is associated with a lower incidence of CRC in their patients.

Objective: To determine the association of improved ADR in physicians with a range of ADR values at baseline with CRC incidence among their patients.

Mortality and rate of hospitalization stratified by patients' BMI in a colonoscopy screening - a cross sectional analysis of data from Polish Colonoscopy Screening Platform.

Background: Currently, it remains unknown whether there is an association between body mass index (BMI) and complications during screening colonoscopy; hence, it remains unclear whether BMI should be considered a risk factor in pre-procedural assessments. The aim of this study was to compare mortality and unplanned hospitalization rates before and after colonoscopy stratified by patients' BMI.

Material And Methods: This was a retrospective cohort study of individuals who underwent screening colonoscopy as part of the Polish Colonoscopy Screening Program (PCSP).

Savings in social expenditures for work incapacity in patients with inflammatory bowel disease depend on access to innovative therapies in Poland.

A Global Perspective on Gastric Cancer Screening: Which Concepts Are Feasible, and When?

Background: Gastric cancer (GC) remains the fifth most common cancer and the third most common cause of cancer-related death globally. In 2022, GC fell into the scope of the updated EU recommendations for targeted cancer screening. Given the growing awareness of the GC burden, we aimed to review the existing screening strategies for GC in high-risk regions and discuss potentially applicable modalities in countries with low-to-intermediate incidence.

Effect of Colonoscopy Screening on Risks of Colorectal Cancer and Related Death.

Background: Although colonoscopy is widely used as a screening test to detect colorectal cancer, its effect on the risks of colorectal cancer and related death is unclear.

Methods: We performed a pragmatic, randomized trial involving presumptively healthy men and women 55 to 64 years of age drawn from population registries in Poland, Norway, Sweden, and the Netherlands between 2009 and 2014. The participants were randomly assigned in a 1:2 ratio either to receive an invitation to undergo a single screening colonoscopy (the invited group) or to receive no invitation or screening (the usual-care group).
