S2 Ep.2: Gastric Adenocarcinoma and Proximal Polyposis of the Stomach (GAPPS)

The 2019 season of the CGA-IGC podcast series, Expert Approach to Hereditary Gastrointestinal Cancers, will focus on the management of extra-colonic features of APC-Associated conditions.In the second episode, Dr. Daniel Worthley, an expert in hereditary cancer syndromes from the South Australian Health and Medical Research Institute, tells the tale of how Gastric Adenocarcinoma and Proximal Polyposis of the Stomach (GAPPS) was first recognized and characterized. GAPPS is caused by a mutation in the promotor region of the APC gene and is inherited in an autosomal dominant fashion. This condition is associated with a significantly increased risk of gastric cancer, but unlike FAP, GAPPS is not associated with tumors in the colon or small bowel. Dr. Worthley reviews the characteristics of this rare condition and current approach to management.
