" Lifetime risk of developing gastric cancer was 8.0% in males vs 5.3% in
females and 4.8% and 9% for MLH1 and MSH2 carriers,
respectively."
Conclusions
Lynchsyndrome mutation carriers have a substantial risk for gastric cancer, in particular patients with an MLH1 or MSH2 mutation. Family history for gastric cancer is a poor indicator for individual risk. Surveillance gastroscopy for Lynchsyndrome patients carrying an MLH1 or MSH2 mutation should therefore be considered.
