The safety of upper gastrointestinal cancer patients in the SARS-CoV-2 outbreak is extremely important and most surgeons need to establish a contingency management. In this study, we present the surgical outlines of patients suffering from upper gastrointestinal cancers. Data were obtained from PubMed, Cochrane Database of Controlled Trials, and SCOPUS of reports up to September 2020. The COVID-19 outbreak makes surgical procedures extremely difficult to be performed. The most common criteria to...

Background Most cases of pancreatic ductal adenocarcinoma (PDAC) are asymptomatic in early stages, and the disease is typically diagnosed in advanced phases, resulting in very high mortality. Tools to identify individuals at high risk of developing PDAC would be useful to improve chances of early detection. Objective We generated a polygenic risk score (PRS) for PDAC risk prediction, combining the effect of known risk SNPs, and carried out an exploratory analysis of a multifactorial score. Metho...

OBJECTIVES Previous meta-analysis including nonrandomized studies showed marginal benefit of underwater endoscopic mucosal resection(U-EMR) compared to conventional EMR(C-EMR) in terms of polypectomy outcomes. We evaluated U-EMR compared to C-EMR in the treatment of colorectal polyps with respect to effectiveness and safety by analyzing only randomized controlled trials(RCTs). MATERIAL AND METHODS PubMed and Cochrane Library databases were searched for RCTs published until 11/2020, evaluating U-...

BACKGROUND Primary gastric melanoma (PGM) is a rare malignant tumour of the stomach with poor prognosis. The aim of this systematic review was to assess the available literature on this entity and to highlight its biological behaviour and preferred treatment approach. METHODS PubMed and Cochrane bibliographical databases were independently searched (last search: 2 February 2020) by two investigators for articles reporting on PGM in the adult population. RESULTS Twenty-five studies met the inclus...
