[Correspondence] Endoscopic surveillance in hereditary diffuse gastric cancer

We read with great interest the Article by Bilal Asif and colleagues.1 The authors conclude that surveillance is a viable alternative to total gastrectomy for individuals with CDH1 variants who declined total gastrectomy. Although we commend the authors for recruiting such a large cohort, we have concerns about the feasibility of the study, and the generalisability of the study findings.
