Evaluation of an educational telephone intervention strategy to improve non-screening colonoscopy attendance: A randomized controlled trial.

Background: Colonoscopy attendance is a key quality parameter in colorectal cancer population screening programmes. Within these programmes, educative interventions with bidirectional contact carried out by trained personnel have been proved to be an important tool for colonoscopy attendance improvement, and because of its huge clinical and economic impact, they have been widely implemented. However, outside of this population programmes, educative measures to improve colonoscopy attendance have been poorly studied and no navigation interventions are usually performed.

The Galectin Family as Molecular Targets: Hopes for Defeating Pancreatic Cancer.

Galectins are a family of proteins that bind β-galactose residues through a highly conserved carbohydrate recognition domain. They regulate several important biological functions, including cell proliferation, adhesion, migration, and invasion, and play critical roles during embryonic development and cell differentiation. In adults, different galectin members are expressed depending on the tissue type and can be altered during pathological processes.

Increased plasma levels of galectin-1 in pancreatic cancer: potential use as biomarker.

Pancreatic ductal adenocarcinoma (PDA) is the most frequent type of pancreatic cancer and one of the deadliest diseases overall. New biomarkers are urgently needed to allow early diagnosis, one of the only factors that currently improves prognosis. Here we analyzed whether the detection of circulating galectin-1 (Gal-1), a soluble carbohydrate-binding protein overexpressed in PDA tissue samples, can be used as a biomarker for PDA.

Endoscopic tattooing of colorectal neoplasms removed by laparoscopy: a proposal for selective marking.

Background And Aim: Preoperative endoscopic tattooing is an effective procedure to identify small intraoperative neoplasms. However, there are no defined criteria with regard to the indications for endoscopic tattooing of these lesions at the time of diagnosis. The aim of this study was to establish endoscopic criteria that allow the selection of patients who will need a tattoo during the diagnostic colonoscopy.

Relationship of colonoscopy-detected serrated polyps with synchronous advanced neoplasia in average-risk individuals.

Background: Serrated cancers account for 10% to 20% of all colorectal cancers (CRC) and more than 30% of interval cancers. The presence of proximal serrated polyps and large (≥10 mm) serrated polyps (LSP) has been correlated with colorectal neoplasia.

Objective: To evaluate the prevalence of serrated polyps and their association with synchronous advanced neoplasia in a cohort of average-risk population and to assess the efficacy of one-time colonoscopy and a biennial fecal immunochemical test for reducing CRC-related mortality.

Study of regulatory T-cells in patients with gastric malt lymphoma: influence on treatment response and outcome.

Purpose: FOXP3+ regulatory T cells (Treg) play an essential role in modulating host responses to tumors and infections. The role of these cells in the pathogenesis of MALT lymphomas remains unknown. The aims of the study were to quantify the number of infiltrating FOXP3+ and CD3+ cells in patients with gastric MALT lymphoma at diagnosis and to study kinetics of these cells and CD20+ tumor cells after treatment and during long-term follow-up.
