Early outcomes of lung resections in non-small cell lung cancer after COVID-19 pneumonia

Abstract

Objective: There is limited literature on patients with a history of COVID-19 pneumonia who underwent anatomical lung resection for non-small cell lung cancer (NSCLC). This study was aimed to share the early postoperative outcomes in patients who underwent lung resection after COVID-19 pneumonia. Materials and methods: We retrospectively evaluated 30 patients who underwent lobectomy with thoracotomy and systematic mediastinal lymph node dissection due to NSCLC in a single center between November 2018 and September 2021. The patients were divided into two groups regarding COVID-19 pneumonia history; the COVID-19 group consisted of 14 patients (46.7%) and the non-COVID-19 group 16 (53.3%) patients. The patients' age, gender, comorbidity, Charlson Comorbidity Index (CCI) score, forced expiratory volume in 1 s (FEV1) value, tumor type and size, resection type, postoperative air leak duration, total drainage volume, drain removal time, postoperative complications, and length of stay (LOS) were recorded. Results: 9 (30%) patients were female, and 21 (70%) were male. The mean age was 62.1 +/- 8.91 years. Our comparison of postoperative air leak duration, total drainage volume, time to drain removal, postoperative complications, and LOS between the COVID-19 and non-COVID-19 groups revealed no statistically significant difference. Conclusion: Anatomical lung resection can be performed safely in NSCLC patients with a history of COVID-19 pneumonia without significant difference in early postoperative morbidity and mortality.
