The CLASS group's vision carries out "research, standardization and promotion of new technologies for laparoscopic gastric cancer surgery, cooperation, mutual benefit, hand in hand to the international academic frontier, leading the scientific development of minimally invasive surgery for gastric cancer in China, and benefiting people's health with high-level clinical research". In the past ten years, CLASS group has become a pioneering force in promoting the progress of laparoscopic surgery for gastric cancer in China. The successful implementation of the CLASS - 01 trail has created a new standard in the clinical research of minimally invasive gastrointestinal surgery and cultivated a high - level surgical clinical research team all over the country. After the successful CLASS - 01 trial, the trials from CLASS - 02 to - 05 has been successfully implemented, CLASS - 06 to - 10 series are in an orderly advancement. On the tenth anniversary of the establishment of the CLASS group, we would like to thank the help from peer, review the development process, look forward to future cooperation, and work together to create a new situation of minimally invasive surgery.

A prospective, multicenter, randomized controlled trial (CLASS-01) of laparoscopic versus open surgery for locally advanced distal gastric cancer provides high-level evidence-based evidence for minimally invasive surgery for locally advanced gastric cancer. The findings showed that the experienced surgeons could perform laparoscopic D2 distal gastrectomy for locally advanced gastric cancer safely and effectively, with significant minimally invasive advantages, which attracting extensive attention in the academic community. In order to correctly understand and scientifically apply the results of this research in clinical practice, this paper summarized the research consensus of CLASS-01 trail for readers, including relevant definitions, surgical indications, device preparation, perioperative management, surgical principles and standards as well as the operational processes and quality control. The relevant standard procedures in this paper are the consensuses which were reached between the researchers when writing the CLASS-01 research plan. The basic principles referred to the international and domestic treatment guidelines and at the same time fully considered the actual situation of laparoscopic gastric cancer surgery in China. It has crucial guiding significance for the scientific development and rational promotion of laparoscopic surgery for gastric cancer in China.
