Professor, Department of Surgery, at Seoul National University Hospital & Seoul National University College of Medicine. Director, Gastric Cancer Center, Seoul National University Hospital.
Dr. Yang is involved in several large scale RCT’s for gastric cancer treatment. He was Korean PI of REGATTA study (Phase III study for the role of gastrectomy in stage IV gastric cancer with a single incurable factor; a collaboratory study between JCOG and KGCA). He is investigators of CLASSIC trial, KLASS trials as well as the Korean PI of a phase II study for the role of neoadjuvant imatinib treatment in large gastric GIST (a collaborator study between Japan and Korea). He is the founding chairman of KLASS (Korean Laparoscopic Gastrointestinal Surgery Study Group). His translational research interests are gastric carcinogenesis, DDS, familial gastric cancer, biomarkers and developing PDX model for gastric cancer. He is Chairman of Board of Directors Korean Society of Surgical Oncology, Chairman elect of Board of Directors Korean Cancer Association, executive council member of IGCA, Honorary fellow of American Surgical Association, Honorary member of European Surgical Association, Honorary International Fellow of Japanese Society of Endoscopic Surgery and a member of Korea Korean Academy of Science and Technology (KAST). He is editor or editorial member of The Journal of Gastric Cancer (official journal of International Gastric Cancer Association), Asian Journal of Endoscopic Surgery, Annals of Surgery, Annals of Surgical Oncology. Dr. Yang gave about 300 invited lectures to international meetings and oversea institutes with occasional live demonstration of gastrectomy (open, laparoscopic or robotic).
Dr. Hyuk Joon Lee, professor of Department of Surgery, is a surgeon who specializes in the surgical management of gastric cancer, which is one of the most common cancers in Korea. He performed about 200-300 gastric cancer cases annually and more than half of them were laparoscopic or robotic gastrectomy. Dr. Lee serves as PI of Korean multicenter phase III randomized controlled trial (RCT) comparing laparoscopic pyloric preserving gastrectomy versus laparoscopic distal gastrectomy (KLASS-04) and also served as sub-PI of multicenter RCT comparing laparoscopic versus open gastric cancer surgery in advanced gastric cancer (KLASS-02). He is also performing research and clinical practice of bariatric surgery (weight reducing surgery) and metabolic surgery (surgery for diabetes). Dr. Lee performs several translational researches to discover novel tissue and serum biomarkers for gastric cancer and to understand the mechanisms of gastric cancinogenesis. Since 2002, he published about 200 SCI papers including Gastroenterology, Annals of Surgery, and Journal of Clinical Oncology
