Preoperative 3-D Virtual Resection Predicts Lung Function After Anatomical Resection in NSCLC Patients: A Prospective Longitudinal Study

What this Trial Is About

Researchers are evaluating a new preoperative method using three-dimensional CT scans and virtual resection simulation to predict lung function after surgery in patients with non-small cell lung cancer (NSCLC) undergoing Video-Assisted Thoracoscopic Surgery (VATS). This study aims to improve accuracy over traditional methods by accounting for differences in lung ventilation caused by tumors or emphysema. It is a prospective, multi-center, longitudinal cohort study involving 60 patients split evenly between those having lobectomy and segmentectomy. Participants will undergo detailed thin-slice chest CT scans and pulmonary function tests before surgery. Using Synapse 3-D software, doctors will create patient-specific 3-D lung models to simulate the planned lung tissue removal and calculate the fraction of ventilated lung to be resected. After surgery, patients will follow standard VATS procedures. The study includes long-term follow-up with pulmonary function tests at 3, 6, and 12 months and CT scans at 6 and 12 months to observe structural lung changes. During the study, participants will have preoperative assessments, surgery, and several postoperative visits for lung function tests and imaging. Researchers will measure how closely the predicted lung function matches actual results at 3 months, as well as longer-term accuracy at 6 and 12 months. They will also study how well the remaining lung compensates after surgery and the effect of any complications on recovery. The total participation spans about one year after surgery, allowing detailed evaluation of lung function and recovery.
