Abstract/OtherAbstract:
In 1998, Guilford et al. identified the hereditary diffuse gastric cancer (HDGC) syndrome, caused by germline alterations at the CDH1 (E-cadherin) gene. To date, 141 probands harboring more than 100 different germline CDH1 alterations, mainly point mutations and large deletions, have been described. In mutation-positive individuals prophylactic total gastrectomy is recommended. The systematic histological study of prophylactic gastrectomies shows intramucosal signet-ring cell carcinoma and pre-invasive lesions including in situ signet ring carcinoma with pagetoid spread of signet ring cells. In 2011, a new hereditary gastric cancer syndrome was identified: gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS). GAPPS is a unique gastric polyposis syndrome with a significant risk of gastric adenocarcinoma, characterized by the autosomal dominant transmission of fundic gland polyposis, with areas of dysplasia or intestinal-type GC, restricted to the proximal stomach, with no evidence of colorectal or duodenal polyposis or other heritable gastrointestinal cancer syndromes.
