Abstract Background Although pneumonectomy has relatively high mortality and morbidity rates, it remains valid in the surgical treatment of lung cancer. This study aims to evaluate the prognostic significance of postoperative complications after pneumonectomy and demonstrate the risk factors related to early postoperative complications. Methods Patients who underwent pneumonectomy for non-small cell lung cancer between January 2008 and May 2021 were included in the study. Factors related to the development of early postoperative complications and overall survival were evaluated by univariate and multivariate analyses. Results A total of 136 patients were included in the study. Early postoperative complications were seen in 33 (24.3%) patients and late postoperative complications in 7 (5.1%) patients. The amount of cigarette smoking, and the operation side were the independent variables that affect the development of early postoperative complications. In multivariate analysis, smoking amount and pericardial invasion were associated with the development of postoperative hemorrhage, and advanced age was associated with the development of postoperative pneumonia. Conclusions Early postoperative complications have a negative effect on the prognosis after pneumonectomy therefore careful patient selection and preoperative risk assessment are essential to minimize the occurrence of complications and improve patient outcomes. Trial registration This observational study was approved by the (Ethical Committee of Dr. Suat Seren Chest Diseases and Chest Surgery Education and Research Center) Institutional Review Board of our center (E-49109414-604.02.02-218625439).

Abstract Background Rapid recovery after surgery is especially important for patients who are scheduled for adjuvant therapy. This study aimed to investigate the effect of video-assisted thoracic surgery (VATS) on chemotherapy referral time and chemotherapy tolerance in patients who underwent lung resection for non-small cell lung cancer. Methods The data of 612 patients who underwent lung resection with the diagnosis of non-small cell lung cancer in our clinic between January 2014 and December 2021 were reviewed. Patients who underwent lobectomy or bilobectomy with systematic mediastinal lymph node dissection and who received at least one cycle of adjuvant chemotherapy were included in the study. The characteristics of the patients, pathological data, postoperative follow-up findings, and the time between the operation and adjuvant chemotherapy were recorded. Results A total of 144 patients who met the criteria were included in the study. The mean age was 61.6 ± 7.9 years. The mean visual analogue scale scores were found to be lower, and the length of hospital stay was found to be shorter in the VATS group compared to thoracotomy. The mean time (days) to initiate chemotherapy after surgery was statistically shorter in the VATS group (48.9 ± 17.6 vs 58.1 ± 27.6, p = 0.049). However, there weren't seen any statistical differences between VATS and thoracotomy groups in terms of mean cycle completed, percentage of planned regimen received, and grade ≥ 3 toxicity rates (p = 0.16, p = 0.18, and p = 0.22, respectively). Conclusions VATS provides faster recovery compared to open surgery and shortens the time for patients to refer to adjuvant chemotherapy.

Abstract Background Bronchopleural fistula (BPF) is a serious complication with high mortality and morbidity that can be seen after lung resections. Although several methods have been described to prevent postoperative BPF it is still unclear which method is the best. In this study, we have used tymopericardial fat flap (TPFF) to cover the bronchial stump in patients after pneumonectomy and aim to show its feasibility and efficacy to prevent BPF. Methods Between January 2013 and June 2021, 187 patients with lung cancer underwent pneumonectomy at our institution. Among them, 53 patients underwent bronchial stump coverage with TPFF. In other 134 patients there wasn’t used any coverage method. Patient characteristics, preoperative status, surgical procedures, perioperative course, pathological findings, and long-term prognoses were evaluated retrospectively. Results Postoperative BPF was observed in 16 (%8.5) patients. It was observed that TPFF was applied in only 1 of the patients who developed BPF. A statistically significant difference was detected between TPFF-coverage with non-coverage groups in terms of postoperative BPF rates (p = 0.044). Other factors associated with the development of postoperative BPF in univariate analysis were right sided pneumonectomy, and re-operation. Conclusion Bronchial stump coverage with TPFF is a feasible and effective method to prevent postpneumonectomy BPF.

Abstract Background VATS lobectomy is a recommended surgical approach for patients with early-stage lung cancer. However, it is still controversial in locally advance disease. This study was conducted to compare intraoperative and postoperative results of VATS and thoracotomy in patients with tumors greater than 5 cm. Methods From January 2014 to December 2018, 849 patients underwent lobectomy or pneumonectomy for the treatment of non-small-cell lung cancer at our center. The inclusion criterion of this study was patients who underwent anatomic lung resection for lung cancer with tumors larger than 5 cm((≥ T3). The patients were divided into two groups: those who underwent video-assisted thoracoscopic surgery (n = 24) and those who underwent thoracotomy (n = 36). Patient characteristics, intraoperative and postoperative results were evaluated by review of the hospital records. Results In the VATS group, mean drainage time and postoperative length of hospital stay were significantly shorter than the thoracotomy group. Kaplan–Meier survival curves showed that overall and recurrence-free survival was longer in the VATS group and this result was statistically significant. Conclusions According to the results of this study, we emphasize that VATS is a feasible surgical procedure for tumors larger than 5 cm.

Background: Predominant histologic subtypes have been reported as predictors of survival of patients with pulmonary adenocarcinoma. Aims: To evaluate the predictive value of histologic classification in resected lung adenocarcinoma using the classification systems proposed by the International Association for the Study of Lung Cancer, American Thoracic Society, European Respiratory Society, and World Health Organization (2015). Study Design: Cross-sectional study. Methods: The histologic classification of a large cohort of 491 patients with resected lung adenocarcinoma (stages I-III) was retrospectively analyzed. The tumors were classified according to their predominant component (lepidic, acinar, papillary, solid, micropapillary, and mucinous), and their predictive values were assessed for clinicopathologic characteristics and overall survival. Results: The patient cohort comprised 158 (32.2%) patients with solid predominant, 150 (30.5%) with acinar predominant, 80 (16.3%) with papillary predominant, 75 (15.3%) with lepidic predominant, 22 (4.5%) with mucinous, and 5 (1.0%) with micropapillary subtype, and 1 (0.2%) with adenocarcinoma in situ. Overall 5-year survival of 491 patients was found to be 51.8%. Patients with lepidic, acinar, and mucinous adenocarcinoma had 70.9%, 59.0%, and 66.6% 5-year survival, respectively, and there was no statistically significant difference between them. Whereas patients with solid, papillary, and micropapillary predominant adenocarcinoma had 41.0%, 40.5%, and 0.0% 5-year survival, respectively. Compared to other histologic subtypes, patients with solid and papillary predominant adenocarcinoma had significantly lower survival than those with lepidic (p
