For small tumors, removing only a segment of the lung (segmentectomy) can preserve more healthy tissue. However, for tumors located deep in the lung, traditional segmentectomy is technically challenging and risks leaving cancer cells behind.In this study, surgeons will use the natural anatomical boundaries-the intersegmental veins and their surrounding thin membranes (septa)-as a guide to precisely remove the target lung segment. This \"septum-guided\" approach aims to ensure the cancer is completely removed while maximizing the preservation of healthy lung function.Participants will be followed for 3 years after surgery to monitor for cancer recurrence and assess their long-term recovery.",[74,75,76,77],"Non-small Cell Lung Cancer","Early-stage Lung Cancer","Deep-seated Lung Nodules","Solid-dominant Lung Cancer",[9,79,80,81,82,83,61],"Intersegmental Septum","VATS Segmentectomy","Precision Surgery","Lung-sparing Surgery","Anatomical Boundary","2026-04-26",{"date":86,"type":87},"2026-05-04","ACTUAL",{"date":89,"type":87},"2026-04-01",{"date":91,"type":68},"2031-04-01",{"name":5,"class":6},1]
