ABSTRACT
One to 3% of gastric cancers are secondary to genetic predisposition, notably hereditary diffuse gastric cancers (HDGC) caused by CDH1 gene mutations. According to French recommendations, in case of CDH1 gene mutation, a prophylactic total gastrectomy should be performed between 20 and 30 years old. This gastrectomy should remove all the gastric mucosa at both extremities (duodenal and esophageal sides). Histopathological examinations of prophylactic total gastrectomies in asymptomatic CDH1-mutated patients reveal microscopic foci of diffuse-type cancer in 90 to 100% of cases. Lymph node involvement and lympho-vascular invasion are extremely rare, justifying the use of a D1-only lymphadenectomy. In the context of prophylaxis, limited lymphadenectomy and the development of minimally invasive oesogastric surgery, the minimally invasive approach might be the preferred approach, in expert centers. Surgical outcomes seem to be similar to those after gastrectomy for cancer. Prophylactic total gastrectomy is the cornerstone of CGDH management, associated with multidisciplinary follow-up and mammary surveillance in women.
