Objective: To investigate the resection range of stage III lung cancer. Methods: 19 cases of stage III lung cancer treated from January 1998 to May 1999 were analyzed. Using expansive lung resection, the surgical treatment of transvaginal lobes, parietal visceral parietal, diaphragm, pericardium, left atrial wall, pulmonary vessels, vena cava invasion of cancer fossa, pleural effusion, and removal of regional lymph nodes was performed. Results: The clinical cure rate was 94.74% and the mortality rate was 5.26%. Conclusion: The importance of surgical decision-making for stage III lung cancer, rational removal of lesions, and protection of normal tissues and organs are the keys to the successful completion of surgery, reduction of postoperative complications, and improvement of curative effect and quality of life of patients.
