EP1.18-08 Pulmonary Lobectomy and Completion Pneumonectomy for Ipsilateral Lung Cancer After Radical Resection

Abstract

Ipsilateral reoperation such as lobectomy and completion pneumonectomy after radical resection of lung cancer is a high-risk operation. We evaluated outcomes after these operations in our hospital. We retrospectively reviewed the records of 27 patients who underwent ipsilateral lobectomy or completion lobectomy for new primary lung cancer or recurrence after pulmonary lobectomy or bi-lobectomy between 1998 and 2017. 9 patients underwent completion lobectomy, of which 4 were right and 5 were left, and 18 patients underwent lobectomy. Mean operative time was 308.7±27.4 minutes, and mean blood loss was 706.9±254.3mL. Blood loss was significantly higher in completion pneumonectomy patients as compared to lobectomy patients, whereas operative time was not different between the operations. There was no perioperative mortality, but intraoperative complications were seen in 4 cases (14.8%), which were 2 pulmonary artery injury, superior venous cava injury and azygos vein injury. Perioperative morbidity was seen in 8 cases (29.6%), and postoperative bronchopleural fistula occurred in one case. Fourteen patients had Pathological stage IA disease, 6 had IB, and 5 stage II or over. As clinical outcome, 5-year overall survival rate was 71.1%. Pulmonary lobectomy or completion pneumonectomy for ipsilateral lung cancer after radical resection were performed in 27 patients without perioperative mortality. Our results strongly suggests that this strategy is a meaningful option for new or recurrent ipsilateral lung cancer.
