Abstract Gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS) is an autosomal dominant inherited disease clinically characterized by gastric cancer and fundic gland polyposis (FGPsis). Germline variants of the APC promotor 1B have been reported as pathogenic variants in GAPPS families. Most GAPPS families have been reported in Western countries; however, only a few GAPPS families have been reported from Japan. Appropriate surveillance including gastrointestinal endoscopy and indication of surgical gastrectomy for GAPPS patients have not been established because of the lack of knowledge of GAPPS and the high positivity rate for Helicobacter pylori infection in Japan. A large-scale investigation of clinicopathological characteristics and pathology is required to establish of a surveillance and treatment strategy for GAPPS.

GAPPSは胃底腺ポリポーシスを背景とした胃癌を発生する新規の常染色体優性遺伝性疾患である.その原因としてAdenomatous polyposis coli(APC)遺伝子promotor 1Bの病的バリアントが報告されている.GAPPSの報告は欧米の家系のみであったが,近年になって本邦からも少数例認められるようになった.しかし,Helicobacter pylori感染率が高い本邦においては疾患の拾い上げが十分でない可能性がある.また,GAPPSの自然史は未だ不明な点が多く,臨床的に高い悪性度を示すものの,予防的胃全摘術の適応を含むサーベイランス方法は十分に定まっていない.今後,本邦をはじめ,より大規模な調査によりGAPPSの臨床病理学的特徴,病態およびサーベイランスのあり方について十分に検討する必要がある.
