Background: The enzyme methylenetetrahydrofolate reductase is engaged in DNA synthesis through folate metabolism. Inhibiting the activity of this enzyme increases the susceptibility to mutations, and damage and aberrant DNA methylation, which alters the gene expression of tumor suppressors and proto-oncogenes, potential risk factors for esophageal cancer.
Aims: This study aimed to investigate the association between methylenetetrahydrofolate reductase 677C>T and methylenetetrahydrofolate reductase 1298A>C polymorphisms and susceptibility to esophageal cancer, by assessing the distribution of genotypes and haplotypes between cases and controls, as well as to investigate the association of polymorphisms with clinical and epidemiological characteristics and survival.
Objectives: Surgery remains the cornerstone treatment modality for gastric cancer, the fifth most common type of tumor in Brazil. The aim of this study was to analyze the surgical treatment outcomes of patients with gastric cancer who were referred to a high-volume university hospital.
Methods: We reviewed all consecutive patients who underwent any surgical procedure due to gastric cancer from a prospectively collected database.
Background: Gastric cancer (GC) patients with advanced age and/or multiple morbidities have limited expected survival and may not benefit from extended lymph node resection. The aim of this study was to evaluate the surgical outcomes of these GC patients who underwent gastrectomy with D1 dissection.
Methods: We retrospectively reviewed all GC patients who underwent gastrectomy with curative intent from 2009 to 2017.
