Abstract    In July 2021, Japanese Gastric Cancer Association (JGCA) published the Version 6th of Japanese Gastric Cancer Treatment Guidelines. Compared with previous version, surgical update included 9 clinical subject, involving 17 related clinical questions. The Version 6th guidelines were still cautious in indications of minimally invasive gastrectomy. Only laparoscopy-assisted distal gastrectomy was strongly recommended for cⅠstage, laparoscopy-assisted proximal/total gastrectomy or robotic surgery was weakly recommended. The guidelines weakly recommended pylorus-preserving gastrectomy for early gastric corpus cancer and proximal gastrectomy for proximal gastric cancer. Omentectomy was weakly recommend for cT3-T4 stage. Splenectomy or hilar lymph node dissection was weakly recommended for lesion invading greater curvature, but was strongly not recommended if not invading. Dissection extent of mediastinal lymph node for cT2+ stage esophagogastric junction cancer mainly depended on esophageal invasion length, which was based on the boundary of 2cm and 4cm. However, for No. 16a2b1, the guidelines couldn’t provide explicit recommendation.
