The Barrett‐associated variants at GDF 7 and TBX 5 also increase esophageal adenocarcinoma risk
2016
Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) represent two stages within the esophagitis-metaplasia-dysplasia-adenocarcinoma sequence. Previously genetic risk factors have been identified that confer risk to BE and EAC development. However, to which extent the genetic variants confer risk to different stages of the BE/EAC sequence remains mainly unknown. In this study we analyzed three most recently identified BE variants at the genes GDF7 (rs3072), TBX5 (rs2701108), and ALDH1A2 (rs3784262) separately in BE and EAC samples in order to determine their risk effects during BE/EAC sequence. Our data show that rs3072 at GDF7 and rs2701108 at TBX5 are also associated with EAC and …
Supportive evidence for FOXP 1 , BARX 1 , and FOXF 1 as genetic risk loci for the development of esophageal adenocarcinoma
2015
The Barrett's and Esophageal Adenocarcinoma Consortium (BEACON) recently performed a genome-wide association study (GWAS) on esophageal adenocarcinoma (EAC) and Barrett's esophagus. They identified genome-wide significant association for variants at three genes, namely CRTC1, FOXP1, and BARX1. Furthermore, they replicated an association at the FOXF1 gene that has been previously found in a GWAS on Barrett's esophagus. We aimed at further replicating the association at these and other loci that showed suggestive association with P < 10(-4) in the BEACON sample. In total, we tested 88 SNPs in an independent sample consisting of 1065 EAC cases and 1019 controls of German descent. We could repl…
Risk and Complication Management in Esophageal Cancer Surgery: A Review of the Literature
2015
Esophagectomy for cancer is a highly complex and demanding two-cavity procedure associated with a considerable morbidity and mortality. There are several controversies with regard to the optimal risk and complication management. Strategies include patient selection, optimization of malnutrition, hospital and surgeon volume, intraoperative anesthesiological and surgical measures, and postoperative management of complications. In this article, we review the literature on these aspects that have an impact on outcomes after esophagectomy.
