Abstract

Individuals with a germline pathogenic variant in the CDH1 gene have a lifetime risk of advanced diffuse gastric cancer (DGC) of up to 10.3% and a 37%-52% risk of breast cancer, specifically the lobular subtype. Guidelines recommend prophylactic gastrectomy between ages 18-40 years for those with a family history of DGC. For patients declining surgery or lacking a family history of DGC, annual endoscopic surveillance according to recommended protocols is an alternative. This case reviews the management of a patient with a history of Roux-en-Y gastric bypass followed one year later by a diagnosis of lobular breast cancer due to a germline CDH1 pathogenic variant.

一种系CDH1致病变异并有Roux-en-Y胃旁路手术史患者的处理考虑。

携带CDH1基因种系致病性变异的个体一生中患晚期弥漫性胃癌（DGC）的风险高达10.3%，患乳腺癌（特别是小叶亚型）的风险为37%-52%。指南建议年龄在18-40岁之间有胃癌家族史的患者进行预防性胃切除术。对于拒绝手术或没有DGC家族史的患者，根据推荐方案进行年度内镜监测是一种选择。本病例回顾了一名患者Roux-en-Y胃旁路手术史，一年后诊断为小叶性乳腺癌，原因是种系CDH1致病性变异。
