The goal is to accurately predict postoperative pulmonary function in patients with non-small cell lung cancer (NSCLC) undergoing Video-Assisted Thoracoscopic Surgery (VATS) anatomical resection.\n\nAccurate prediction of postoperative lung function is crucial for patient safety. Traditional methods, such as segment counting, often lack precision because they assume all lung segments contribute equally to function, ignoring variations caused by tumors or emphysema. This study utilizes 3-D \"virtual resection\" to quantify the \"Planned Resected Ventilated Lung Volume Fraction\" (pRVLVF) before surgery.\n\nThe study will recruit 60 participants divided into two groups: those undergoing lobectomy (n=30) and those undergoing segmentectomy (n=30). Participants will undergo standard thin-slice CT scans and pulmonary function tests (PFT) before surgery. Postoperatively, lung function and recovery will be tracked at 3, 6, and 12 months to develop a dynamic prediction model and evaluate the compensatory capacity of the residual lung.",[53,54,55],"Non-small Cell Lung Cancer","Lung Cancer","Lung Neoplasms",[57,58,59,60,61,62,63],"Three-dimensional virtual resection","Pulmonary Function Prediction","Ventilated Lung Volume Fraction (VLVF)","VATS Anatomical Resection","Segmentectomy","Lobectomy","Postoperative Compensation Coefficient","2026-05-10",{"date":66,"type":67},"2026-05-13","ACTUAL",{"date":69,"type":67},"2026-04-07",{"date":71,"type":49},"2027-06-30",{"name":5,"class":6},1]
