OBJECTIVE: The screening for colorectal cancer (CRC) through the fecal occult blood test (FOBT) has achieved high implementation in Spain, although participation rates are still not optimal. At the same time, available data show significant differences in participation both among autonomous communities and among different sociodemographic groups, which raises various equity issues. This study aimed to conduct an exploratory analysis from a qualitative perspective on the attitudes, perceptions, and social images that the target population for colorectal cancer screenings holded regarding them, as well as the barriers and areas for improvement identified through these...

Post-colonoscopy colorectal cancer (PCCRC) is a tumor that appears after a normal colonoscopy before the established time for the endoscopic follow up. Its origin reflects the quality of the colonoscopy and the different tumoral biologics between the CRC and the CRCPC. Our aim is to describe the characteristics of the PCCRC in our region, to identify risk factors, to discriminate the potential causes according to the World Endoscopý Organization (WEO) and to determine its impact in the patient's survival...

Recently, biallelic MSH3 germline pathogenic/likely pathogenic variants have been recognised as a rare cause of adenomatous polyposis. We present a 49-year-old woman who was admitted to our high-risk colorectal cancer clinic after incidental detection of a biallelic MSH3 (likely) pathogenic variant when tested for the germline (likely) pathogenic variants in hereditary breast and ovarian cancer related genes. The focus of this case report is to describe the genotype and phenotype of our patient with MSH3-related adenomatous polyposis...

Posttranslational modifications of epigenetic modifiers provide a flexible and timely mechanism for rapid adaptations to the dynamic environment of cancer cells. SIRT1 is an NAD+ -dependent epigenetic modifier whose activity is classically associated with healthy aging and longevity, but its function in cancer is not well understood. Here, we reveal that 1α,25-dihydroxyvitamin D3 (1,25(OH)2 D3, calcitriol), the active metabolite of vitamin D (VD), promotes SIRT1 activation through auto-deacetylation in human colon carcinoma cells, and identify lysine 610 as an essential driver of SIRT1 activity...

Colorectal cancer (CRC) is a complex disease, determined by genetic, environmental and lifestyle-associated risk factors. Genetic (inherited) factors have great influence on its development; however, most cases of CRC are sporadic and gradually develop over several years. The main environmental risk factors are associated with b-catenin signaling pathway, including obesity, lack of physical activity, consumption of red and processed meats, alcoholism, and smoking. The pathway is related to cell homeostasis regulation and cell self-renewal during embryogenesis and adulthood...

BACKGROUND: COVID-19 pandemic had a negative impact on colorectal cancer (CRC) screening programs. OBJECTIVE: The care strategy was modified throughout the pandemic, this paper evaluates its impact and short-term consequences. METHODS: A retrospective, descriptive and cross-sectional study was carried out in a private ambulatory endoscopic center, in average risk subjects. The study compared two periods: pre-pandemic and pandemic (subdivided into pre-vaccination and vaccination)...

BACKGROUND: The aim of the study was to determine the socioeconomic and demographic factors associated with advanced colorectal cancer (CRC) presentation at our institution. METHODS: From January 2009 to January 2018, patients that underwent CRC surgery at our institution were included and retrospectively analyzed. Univariate and multivariate logistic regression were used to determine independent risk factors for presenting with advanced CRC. RESULTS: A total of 277 patients were included, 53...

The use of near-infrared fluorescence imaging with indocyanine green (ICG) is actually considered as a very useful tool in decision-making strategy during challenging surgical procedures with a growing evidence in the literature. Our aim is to perform a systematic review focusing on ICG applications in gastrointestinal surgery. We conducted a systematic review with narrative synthesis in conformity with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using PubMed, Medline, and EMBASE databases to identify articles describing the gastrointestinal perioperative use of ICG in children...
