Abstract
Extended pulmonary metastasectomy has become feasible in patients with extrapulmonary metastases and multiple or bilateral pulmonary metastases. Even peritoneal dissemination is considered to be curable in modern medicine. Therefore, it is necessary to analyze the prognosis of patients undergoing complete pulmonary metastasectomy. A total of 80 patients who underwent pulmonary resection for lung metastases were retrospectively analyzed. The eligibility criteria for the present study were as follows: i) the primary tumor was controlled; ii) if extrapulmonary metastases (including peritoneal dissemination) existed, these were controlled by local treatment or such treatment was planned; iii) the one to three months follow-up computed tomography (CT) following the first assessment revealed no increase of pulmonary metastatic disease; iv) pulmonary metastases could be resected completely. The overall 5- and 10-year survival rates were 71.7 and 41.5%, respectively. Applying the extended criteria for surgery, the present study demonstrated that pulmonary metastasectomy resulted in a good patient prognosis.
