Walter Lai, M.D., Ph.D.
Clinical Fellow

Residency: Einstein Medical Center (Philadelphia, PA)

Medical Degree: Albert Einstein College of Medicine

Year in Program: 3rd Year

Research Projects: CDH1 mutation is linked to familial diffuse gastric cancer, and the current management for CDH1 mutant carriers is either undergoing annual gastric mapping for cancer surveillance or prophylactic total gastrectomy; both of which have their own disadvantages. Total gastrectomy can cause significant post-op morbidities, but the surveillance approach also suffers from low sensitivity. I am exploring confocal endoscopy versus magnifying endoscopy in conjunction with artificial intelligence to improve malignancy detection. In addition, I will be part of a CDH1 gastric cancer consortium that defines the nomenclature of endoscopic findings in CDH1 carriers, to harmonize data collected between different study sites in the future.
