About

Dae Hyun Yang is a leading surgical oncologist whose research has fundamentally shaped the minimally invasive treatment of gastric cancer. His work centers on comparing robotic and laparoscopic gastrectomy, with a focus on surgical outcomes, patient selection, and postoperative quality of life. Yang’s landmark multicenter prospective study, which has garnered over 316 citations, provided critical evidence comparing the short-term outcomes and financial costs of robotic versus laparoscopic gastrectomy for gastric adenocarcinoma—a pivotal contribution at a time when robotic surgery was rapidly expanding without robust supporting data. He further refined this work through subgroup analyses (66 citations) identifying which patients may derive the greatest benefit from robotic approaches. Demonstrating a holistic view of surgical success, Yang also led prospective evaluations of postoperative quality of life following minimally invasive gastrectomy, emphasizing patient-reported outcomes in the Korean multicenter robotic gastrectomy trial. His research has been instrumental in guiding evidence-based surgical decision-making, balancing technological innovation with clinical efficacy and patient well-being. Yang’s contributions continue to influence surgical practice and trial design in gastric cancer care worldwide.
