Abstrakt:	Objective: The optimal surgical approach for second primary metachronous lung cancer (MPLC) remains unclear. Our aim is to evaluate the morbidity and prognostic value based on the extent of surgical resection in MPLC. Methods: Retrospective study of 84 patients with a history of anatomical resection for lung cancer and MPLC surgically treated between January 2010 and December 2020. Results: The interval between the initial primary tumor and the second was 50.38±32.89 months. The second resection was contralateral in 43 patients (51.2%) and ipsilateral in 41 (48.8%). Thirty-six patients (42.9%) underwent a second anatomical resection, and in 48 patients (57.1%), it was non-anatomical. Postoperative complications were observed in 29 patients (34.5%) after the second lung resection. According to the Clavien-Dindo classification, 95.2% were mild (Clavien-Dindo I-II), and a single patient died (1.2%) in the postoperative period (Grade V). Prolonged air leak (p=0.037), postoperative arrhythmias (p=0.019) and hospital stay showed significant differences depending on the extent of surgery in ipsilateral resections. The main histological type was adenocarcinoma (47.6%) and the median tumor size was 17.74±11.74mm. The overall survival was 58.07 months (95% CI 49.29-66.85) for patients undergoing anatomical resection and 50.97 months (95% CI 43.31-58.63) for non-anatomical without significant differences (p=0.144). The disease-free survival after the second surgery was 53.75 months (95% CI 45.28-62.23) for anatomical resection and 41.34 months (95% CI 33.04-49.65) for non-anatomical group. Conclusion: Second anatomical resections provide good long-term outcomes and have been shown to provide better disease-free survival compared to non-anatomical resections in properly selected patients.
