Abstract

Obtaining evidence in surgical oncology requires the time and effort of several surgeons. More than 15 years were needed even for D2 lymph node dissection to be generally approved in the Western world after completion of phase III studies. The Japanese Gastric Cancer Society, with a history of more than 50 years, has contributed to many clinical trials based on the Japanese Clinical Oncology Group during the past 30 years. During the past 10 years, the clinical significance of D2 lymphadenectomy, the left thoracotomy approach, para-aortic node dissection, splenectomy, and bursectomy has been evaluated in phase III studies. Although only a few studies have been completed, the laparoscopic approach and robotic surgery have been increasingly performed. Here we review recent evidences for surgical treatment of gastric carcinoma, focusing on Japanese clinical trials.
