This is a two-arm, parallel-group randomized clinical trial. Routine perioperative care would be performed in volunteers with primary early lung cancer. The study will enroll approximately 300 volunteers to compare the progression-free or overall survival in patients undergoing video-assisted thoracoscopic surgery (VATS) for primary lung tumors between propofol and sevoflurane for the maintenance of anesthesia.
