Summary
Brief summary (as posted)
This study aims to validate a novel preoperative assessment strategy using three-dimensional (3-D) computed tomography (CT) reconstruction and virtual resection simulation. 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. Accurate 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. The 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.

Primary outcomes (1)
- measure
- Mean Absolute Error (MAE) of Predicted Postoperative FEV1
- timeFrame
- 3 months post-operation
- description
- The accuracy of the preoperative 3D virtual resection model will be evaluated by calculating the Mean Absolute Error (MAE) between the predicted FEV1 and the actual measured FEV1. A lower MAE indicates higher prediction accuracy. The study targets an MAE of less than 180 mL.
