Abstrakt: Background: CDH1 (E-cadherin) genetic mutations are associated with a 30%-70% increased lifetime risk of hereditary diffuse gastric cancer (HDGC). Although prophylactic total gastrectomy (PTG) reduces long-term risk of gastric cancer, the associated morbidity and mortality remain unclear. This systematic review aims to characterise postoperative surgical outcomes in patients undergoing total gastrectomy.
Methods: A systematic literature search was performed for studies reporting endoscopic surveillance, surgical and pathological outcomes for patients with CDH1 mutation undergoing a total gastrectomy.
Results: Thirty-nine studies included 1849 patients, of which 96% had a CDH1 (n = 1777) or CTNNA1 (n = 3) mutation. Endoscopy outcomes were reported for 1640 patients. Cancer foci were identified in 32% (n = 523/1640) and 71% of these patients went on to have a total gastrectomy (n = 369/523). The remaining 78% of patients did not have cancer foci detected on endoscopy (n = 1117/1640). Of these patients, 62% underwent a total gastrectomy (n = 688/1117) and 81% were found to have cancer on surgical histology (n = 556/688). Pathological staging was reported for 790 patients undergoing surgery, of which 68% had pT1 disease (n = 537). Postoperative complications were reported for 430 patients across 23 studies, with the most common complications being anastomotic strictures (25%), anastomotic leaks (13%), wound infections (12%) and pulmonary complications (11%). Only one postoperative death was reported within 30 days.
Conclusion: Rates of early cancers are high in CDH1 patients undergoing PTG, highlighting the need for improvement in reliable endoscopic surveillance. Although postoperative mortality in this surgical cohort remains low, high rates of postoperative complications warrant careful patient counselling.
