The treatment of lung cancer is evolving rapidly, and current evidence is beginning to show that new approaches for thoracic procedures and treatments have excellent outcomes and quality of life related results. Advances in diagnostic methods, earlier diagnosis and the important requirement of preserving as much lung function as possible, have made lung cancer surgery evolve to become as Minimally Invasive as possible. This of course has led to the widespread adoption of VATS and Uniportal VATS in Asia. In addition, lung function preserving operations such as segmentectomy and sub lobar radical resections also have a high interest in Asia Pacific and are being adopted as a new procedure strategy. There is one big study that are being conducted in Japan (JCOG0802), on the oncological outcomes of VATS segmentectomy and its comparison with the more traditional VATS lobectomy. However, based on the current report, there is still many interested data reported to discussion. We hope there is a chance to share some discussing point about this study.
