RESUMO
INTRODUCTION: The Nuss procedure for pectus excavatum requires that the sternal elevation be maintained by indwelling metal bars that are traditionally removed approximately 3 y after the repair. METHODS: A retrospective cohort study was conducted of all patients who underwent primary Nuss repair from 2007 to 2018 in two institutions and had a follow-up of at least 24 mo. Pectus bars had been left in place beyond 3 y in patients concerned over possible recurrence after bar removal. Structured interviews were held to assess pain, chest tightness, or other discomfort, and any adverse events related to pectus bars. Results were compared between patients in whom pectus bars were removed after 3 y (standard group) and those in whom bars were left in place longer (extended bar duration group). RESULTS: Two hundred and thirty-one patients (91% males, mean age 23.9 ± 8.3, mean Haller index 4.9 ± 2.3) were included. Bar duration was 30.6 ± 6.6 mo in the standard group (51 patients) versus 69.1 ± 26.3 mo in the extended group (180 patients). Some discomfort was reported by 81.6% in the standard group versus 62.9% in the extended group (P = 0.033), and discomfort occurring at least monthly or more often was only reported by 30% in the standard versus 30.3% in the extended group (P = 1.000). Quality of life improved in 92.6% of the standard group versus 94.7% of the extended group (P = 1.000). No significant adverse events were reported in either group. CONCLUSIONS: Our data suggest that an extended bar duration after the Nuss repair may not cause any adverse event nor negatively affect quality of life.

BACKGROUND: High-energy devices allow better vessel sealing compared with monopolar electrocautery and could improve the outcomes of surgical operations. The objective of the study was to compare tissue dissection by the LigaSure™ device with that by monopolar electrocoagulation for thoracoscopic lobectomy and lymphadenectomy. METHODS: This pragmatic, parallel group, prospective randomized controlled trial was funded by the Medtronic External Research Program (ISR-2016-10,756) and registered at www. CLINICALTRIALS: gov (NCT03125798). The study included patients aged 18 years or older, who had undergone thoracoscopic lobectomy with lymphadenectomy at the Department of Thoracic Surgery of Poznan University of Medical Sciences between May 3, 2018, and November 4, 2021. Using simple randomization, the patients were assigned to undergo tissue dissection with either the LigaSure device (study group) or monopolar electrocautery (control group). Participants and care givers, except operating surgeons, were blinded to group assignment. The primary outcome was postoperative chest drainage volume. Secondary outcomes were change of the esophageal temperature during subcarinal lymphadenectomy and C-reactive protein level 72 h after surgery. RESULTS: Study outcomes were analyzed in 107 patients in each group. We found no differences between the study and control groups in terms of chest drainage volume (550 vs. 600 mL, respectively; p = 0.315), changes in esophageal temperature (- 0.1 °C vs. - 0.1 °C, respectively; p = 0.784), and C-reactive protein levels (72.8 vs. 70.8 mg/L, respectively; p = 0.503). The mean numbers of lymph nodes removed were 12.9 (SD: 3.1; 95% CI, 12.4 to 13.5) in the study group and 11.6 (SD: 3.2; 95% CI, 11.0 to 12.2) in the control group (p < 0.001). CONCLUSIONS: The use of the LigaSure device did not allow to decrease the chest drainage volume, local thermal spread, and systemic inflammatory response. The number of lymph nodes removed was higher in patients operated with the LigaSure device, which indicated better quality of lymphadenectomy.

INTRODUCTION: Primary spontaneous pneumothorax (PSP) is a relatively common disease. Different studies have been published but lung resection, when no emphysema-like changes (ELC) are detected, is unclear. The aim of our study is to retrospectively investigate the role of lung resection of the apex of the lung in patients with no ELC. METHODS: This is a retrospective multicenter study of 516 patients who underwent surgical treatment of PSP with no ELC between January 2007 and December 2017. Patients were divided into two groups: pleurodesis alone group, only mechanical pleurodesis performed (53 patients), and apical resection group, apical resection of the lung and mechanical pleurodesis performed (463 patients). The following were the primary end points considered: recurrence rate and perioperative complications; the following were the secondary end points considered: length of stay, chest tube removal, residual pleural space, prolonged air leak, and reoperation rate. RESULTS: No differences were found in the baseline and operative characteristics of the two groups. Both primary end points were statistically different: recurrence rate (15.1% versus 6.5%, P = 0.023) and perioperative complications (18.9% versus 7.3%, P = 0.004). Among secondary end points length of stay (6.94 versus 5.55, P = 0.033) and prolonged air leak (15.1% versus 4.3%, P = 0.001) were statistically different. On multivariate analysis, lung resection emerged as a protective factor for recurrence (hazard ratio 0.182, P < 0.001). CONCLUSIONS: In our experience, apical lung resection in patients without ELC may reduce recurrence rate and perioperative complications when compared with pleurodesis alone.

BACKGROUND: Air leak is the most common complication after lung resection and leads to increased length of hospital (LOH) stay or patient discharge with a chest tube. Management by autologous blood patch pleurodesis (ABPP) is controversial because few studies exist, and the technique has yet to be standardized. METHODS: We retrospectively reviewed patients undergoing ABPP for prolonged air leak (PAL) following lobectomy in three centers, between January 2014 and December 2019. They were divided into two groups: Group A, 120 mL of blood infused; Group B, 60 mL. Propensity score-matched (PSM) analysis was performed, and 23 patients were included in each group. Numbers and success rates of blood patch, time to cessation of air leak, time to chest tube removal, reoperation, LOH, and complications were examined. Univariate and multivariate analysis of variables associated with an increased risk of air leak was performed. RESULTS: After the PSM, 120 mL of blood is statistically significant in reducing the number of days before chest tube removal after ABPP (2.78 vs. 4.35), LOH after ABPP (3.78 vs. 10.00), and LOH (8.78 vs. 15.17). Complications (0 vs. 4) and hours until air leak cessation (6.83 vs. 3.91, range 1-13) after ABPP were also statistically different (p < 0.05). Air leaks that persisted for up to 13 hours required another ABPP. No patient had re-operation or long-term complications related to pleurodesis. CONCLUSION: In our experience, 120 mL is the optimal amount of blood and the procedure can be repeated every 24 hours with the chest tube clamped.

OBJECTIVES: To evaluate the clinico-radiological findings of acute fibrinous and organizing pneumonia (AFOP) in the literature according to whether a surgical or non-surgical biopsy was performed, as well as to identify prognostic predictors. METHODS: We searched the Embase and OVID-MEDLINE databases to identify studies that presented CT findings of AFOP and had extractable individual patient data. We compared the clinical and CT findings of the patients depending on whether a surgical or non-surgical biopsy was performed and identified survival predictors using a multivariate logistic regression analysis. RESULTS: Eighty-one patients (surgical biopsy, n = 52; non-surgical biopsy, n = 29) from 63 studies were included. The surgical biopsy group frequently experienced an acute fulminant presentation (p = .011) and dyspnea (p = .001) and less frequently had a fever (p = .006) than the non-surgical biopsy group. The surgical biopsy group had a worse prognosis than the non-surgical biopsy group in terms of mechanical ventilation and mortality (both, p = .023). For survival analysis, the patients with the predominant CT finding of patchy or mass-like air-space consolidation survived more frequently (p < .001) than those with other CT findings. For prognostic predictors, subacute indolent presentation (p = .001) and patchy or mass-like air-space consolidation on CT images (p = .002) were independently associated with good survival. CONCLUSIONS: Approximately one-third of alleged AFOP cases in the literature were diagnosed via non-surgical biopsy, but those cases had different symptomatic presentations and prognosis from surgically proven AFOP. Subacute indolent presentation and patchy or mass-like air-space consolidation at the presentation on CT images indicated a good prognosis in patients with AFOP. KEY POINTS: ⢠Acute fibrinous and organizing pneumonia (AFOP) cases diagnosed via non-surgical biopsy had different symptomatic presentations and prognosis from surgically proven AFOP. ⢠Subacute indolent presentation and patchy or mass-like air-space consolidation on CT images indicated a good prognosis in patients with acute fibrinous and organizing pneumonia.

The use of extracorporeal membrane oxygenator instead of standard cardiopulmonary bypass during lung transplantation is debatable. Moreover, recently, the concept of prolonged postoperative extracorporeal membrane oxygenator (ECMO) support has been introduced in many transplant centers to prevent primary graft dysfunction (PGD) and improve early and long-term results. The objective of this study was to review the results of our extracorporeal life support strategy during and after bilateral sequential lung transplantation (BSLT) for pulmonary artery hypertension. We review retrospectively our experience in BSLT for pulmonary artery hypertension between January 2010 and August 2018. A total of 38 patients were identified. Nine patients were transplanted using cardiopulmonary bypass (CPB), in eight cases CPB was followed by a prolonged ECMO (pECMO) support, 14 patients were transplanted on central ECMO support, and seven patients were transplanted with central ECMO support followed by a pECMO assistance. The effects of different support strategies were evaluated, in particular in-hospital morbidity, mortality, incidence of PGD, and long-term follow-up. The use of CPB was associated with poor postoperative results and worse long-term survival compared with ECMO-supported patients. Predictive preoperative factors for the need of intraoperative CPB instead of ECMO were identified. The pECMO strategy had a favorable effect to mitigate postoperative morbidity and mortality, not only in intraoperative ECMO-supported patients, but even in CPB-supported cases. In our experience, ECMO may be considered as the first choice circulatory support for lung transplantation. Sometimes, in very complex cases, CBP is still necessary. The pECMO strategy is very effective to reduce incidence of PGD even in CPB-supported patients.

Mediastinal infection caused by anastomotic leak is hard to cure, mainly because the poor drainage at the site of mediastinal infection leads to persistent cavity infection, which in turn becomes a refractory mediastinal abscess cavity after minimally invasive esophagectomy (MIE)-McKeown. Herein, we explored sternocleidomastoid (SCM) muscle flaps and emulsified adipose tissue stromal vascular fraction containing adipose-derived stem-cells to address this issue. We studied 10 patients with esophageal cancer who underwent MIE-McKeown + 2-field lymphadenectomy and developed anastomotic and mediastinal leak and received new technology treatment in the Affiliated Cancer Hospital of Zhengzhou University from June 2018 to March 2022. The clinical data and prognosis of the patients were collected and analyzed. A total of 5 patients received this surgery, and no other complications occurred during the perioperative period. Among the 5 patients, 1 patient was partially cured, and 4 patients were completely cured. During the follow-up 3 months postoperatively, all these 5 patients could eat regular food smoothly, and no relapse of leak and mediastinal infection occurred. The new surgical method has achieved good results in the treatment of anastomotic leak. Compared with the traditional thoracotomy, it is a less invasive and feasible surgical approach, which can be used as a supplement to the effective surgical treatment of cervical anastomotic leak contaminating the mediastinum.
RESUMO
Introduction: The outcomes of lung cancer surgery depend on the patients' nutritional status. Body fat percentage (BF%) is one of the indicators of body composition and nutritional status. Direct measurement of BF% is complicated, requires significant resources and is rarely performed. The CUN-BAE (Clínica Universidad de Navarra - Body Adiposity Estimator) index has been shown to accurately predict BF% is several clinical settings, but its relation to the outcomes of lung surgery has not been reported so far. Aim: To determine the relation of the BF% to the outcomes of thoracoscopic lobectomy. Material and methods: This retrospective study included 1,183 patients who underwent thoracoscopic lobectomy for non-small cell lung cancer between June 1999, and September 2019 at one department. BF% was calculated according to the Clínica Universidad de Navarra - Body Adiposity Estimator equation. The primary endpoints were postoperative complications and long-term survival. Results: Univariate analysis showed that higher BF% was related to lower incidence of complications (p = 0.001), including prolonged air leak (p < 0.001), atelectasis (p < 0.05), psychosis (p < 0.001), reoperations (p < 0.05), and shorter chest drainage (p = 0.001) and hospitalization duration (p < 0.001). Multivariate analysis showed that higher BF% was correlated with lower risk of complications (p = 0.005; OR = 0.964; 95% CI: 0.940 to 0.989), including prolonged air leak (p < 0.001; OR = 0.923; 95% CI: 0.886 to 0.962), and shorter duration of chest drainage (p < 0.001; B = -0.046; 95% CI: -0.069 to -0.023) and hospitalization (p < 0.001; B = -0.112; 95% CI: -0.176 to -0.048). Cox proportional hazards regression analysis showed that BF% was not related to long-term survival. Conclusions: Body fat percentage is a valuable tool that can help predict the short-term outcomes of minimally lobectomy for lung cancer.
RESUMO
BACKGROUND: The Nuss procedure is the primary treatment for pectus excavatum (PE), but patient expectations are not always met. In our unit, our standard approach in the last few years has been the routine application of two bars instead of one. We aimed to retrospectively assess the impact of this approach on patient satisfaction, quality of life (QoL) and safety. METHODS: A retrospective study included 182 patients over 16 years old who underwent the Nuss procedure for PE between January 2007 and September 2021. Patients were categorized into one-bar or two-bar correction groups. Propensity score matching (PSM) was used, resulting in 30 patients in each group. Primary endpoints were QoL and cosmetic satisfaction, while secondary endpoints included complications and recurrence. RESULTS: After PSM, both groups showed similar general characteristics. Patients treated with two bars reported fewer psychological complaints post-surgery (93.3% vs. 73.3%, p = 0.031). There were no significant differences in QoL improvement (96.7% in both groups, p = 0.197), perioperative complications (p = 0.771) or recurrence (one patient in the one-bar group, p = 1.000). CONCLUSIONS: Our study reveals that patients undergoing the Nuss Procedure for PE with two bars exhibit comparable clinical outcomes and QoL to those with one bar. However, patients with two bars may have higher levels of psychological well-being and satisfaction, indicating potential benefits associated with this approach. These findings suggest potential advantages of the two-bar approach, but further research with larger sample sizes is warranted to confirm these observations.
RESUMO
Lymphadenectomy is an essential part of complete surgical operation for non-small cell lung cancer (NSCLC). This retrospective, multicenter cohort study aimed to identify factors that influence the lymphadenectomy quality. Data were obtained from the Polish Lung Cancer Study Group Database. The primary endpoint was lobe-specific mediastinal lymph node dissection (L-SMLND). The study included 4271 patients who underwent VATS lobectomy for stage IA NSCLC, operated between 2007 and 2022. L-SMLND was performed in 1190 patients (27.9%). The remaining 3081 patients (72.1%) did not meet the L-SMLND criteria. Multivariate logistic regression analysis showed that patients with PET-CT (OR 3.238, 95% CI: 2.315 to 4.529; p < 0.001), with larger tumors (pT1a vs. pT1b vs. pT1c) (OR 1.292; 95% CI: 1.009 to 1.653; p = 0.042), and those operated on by experienced surgeons (OR 1.959, 95% CI: 1.432 to 2.679; p < 0.001) had a higher probability of undergoing L-SMLND. The quality of lymphadenectomy decreased over time (OR 0.647, 95% CI: 0.474 to 0.884; p = 0.006). An analysis of propensity-matched groups showed that more extensive lymph node dissection was not related to in-hospital mortality, complication rates, and hospitalization duration. Actions are needed to improve the quality of lymphadenectomy for NSCLC.
RESUMO
OBJECTIVE: Air leak (AL) is the most frequent adverse event after thoracic surgery. When AL occurs, the concentration of the principal gas in the pleural space should be similar to that of air exhaled. Accordingly, we tried to develop a new method to identify AL by analyzing pCO2 levels in the air flow from the chest drainage using capnography. METHODS: This is a prospective observational study of 104 patients who underwent VATS surgery between January 2020 and July 2021. Digital drainage systems were used to detect AL. RESULTS: Eighty-two patients (79%) had lung resection. Among them, 19 had post-operative day 1 air leaks (median 67 ml/min). AL patients had higher intrapleural CO2 levels (median 24 mmHg) (p < 0.001). Median chest drainage duration was 2 days (range 1.0-3.0). Univariable logistic regression showed a linear and significant association between intrapleural CO2 levels and AL risk (OR 1.26, 95% CI 1.17-1.36, p < 0.001, C index: 0.94). The Univariable Gamma model demonstrated that an elevation in CO2 levels was linked to AL on POD1 (with an adjusted mean effect of 7.006, 95% CI 1.59-12.41, p = 0.011) and extended duration of drainage placement (p < 0.001). CONCLUSIONS: Intrapleural CO2 could be an effective tool to assess AL. The linear association between variables allows us to hypothesize the role of CO2 in the identification of AL. Further studies should be performed to identify a CO2 cutoff that will standardize the management of chest drainage.
RESUMO
The accurate selection of the recipient is a crucial aspect in the field of lung transplantation (LTX), especially if patients were previously affected by oncological disease. The aim of this bicentric retrospective study was to evaluate short- and long-term outcomes in patients with previous oncological disease or unknown neoplasia found on native lungs submitted to LTX, compared to a control group. A total of 433 patients were included in the analysis, 31 with malignancies (Group 1) and 402 without neoplastic disease (Group 2). The two groups were compared in terms of short- and long-term outcomes. Patients in Group 1 were older (median age 58 years vs. 50 years, p = 0.039) and mostly affected by idiopathic pulmonary fibrosis (55% vs. 40% p = 0.002). Even though in Group 1 a lower rate of late post-operative complications was found (23% vs. 45%, p = 0.018), the median overall survival (OS) was lower compared to the control group (10 months vs. 29 months, p = 0.015). LTX represents a viable therapeutic option for patients with end-stage lung disease and a history of neoplastic disease. However, every case should be carefully debated in a multidisciplinary setting, considering oncological (histology, stage, and proper disease free-interval) and clinical factors (patient's age and comorbidities). A scrupulous post-transplant follow-up is especially mandatory in those cases.
RESUMO
BACKGROUND: Sleeve resection is currently the gold standard procedure for centrally located non-small cell lung cancer (NSCLC). Extended sleeve lobectomy (ESL) consists of an atypical bronchoplasty with resection of >1 lobe and carries several technical difficulties compared with simple sleeve lobectomy (SSL). Our study compared the outcomes of ESL and SSL for NSCLC. METHODS: This multicenter, retrospective, cohort study included 1314 patients who underwent ESL (155 patients) or SSL (1159 patients) between 2000 and 2018. The primary end points were 30-day and 90-day mortality, overall survival (OS), disease-free survival (DFS), and complications. RESULTS: No differences were found between the 2 groups in general characteristics and surgical and survival outcomes. In particular, there were no differences in early and late complication frequency, 30- and 90-day mortality, R status, recurrence, OS (54.26 ± 33.72 months vs 56.42 ± 32.85 months, P = .444), and DFS (46.05 ± 36.14 months vs 47.20 ± 35.78 months, P = .710). Mean tumor size was larger in the ESL group (4.72 ± 2.30 cm vs 3.81 ± 1.78 cm, P < .001). Stage IIIA was the most prevalent stage in ESL group (34.8%), whereas stage IIB was the most prevalent in SSL group (34.3%; P < .001). The multivariate analyses found nodal status was the only independent predictive factor for OS. CONCLUSIONS: ESL gives comparable short- and long-term outcomes to SSL. Appropriate preoperative staging and exclusion of metastases to mediastinal lymph nodes, as well as complete (R0) resection, are essential for good long-term outcomes.

Thymomas are rare epithelial tumors of the mediastinum with relatively good prognosis compared to other thoracic malignancies. Surgery is considered the best treatment and the most important determinant of long-term survival even in advanced stages. Nevertheless, complete resection may be challenging and require a multimodality approach. We present a case of a stage IVa thymoma surgically treated. The superior vena cava was completely occluded and, after resection, reconstruction was deemed unnecessary due to sufficient venous return through the azygos-inferior vena cava system. In our opinion, despite the morbidity of surgery in advanced thymomas, it should always be considered in expert hands.
RESUMO
PURPOSE: SMARCA4-deficient thoracic tumors are rapid aggressive malignancies, often diagnosed at an advanced and inoperable stage. The value of pulmonary resection for resectable SMARCA4-deficient thoracic tumors is largely unknown. METHODS: In this observational study, we included 45 patients who received surgery for stage I-III SMARCA4-deficient tumors. We compared the molecular, clinicopathological characteristics and survival between SMARCA4-dNSCLC and SMARCA4-deficient undifferentiated tumor (SMARCA4-dUT) patients. RESULTS: Thirty-four SMARCA4-dNSCLC and 11 SMARCA4-dUT patients were included in this study. Molecular profiles were available in 33 out of 45 patients. The most common mutated gene was TP53 (21, 64%), and followed by STK11 (9, 27%), KRAS (5, 15%), FGFR1 (4, 12%) and ROS1 (4, 12%). There were 3 patients that harbored ALK mutation including 1 EML4-ALK rearrangement. There were 2 patients that harbored EGFR rare site missense mutation. SMARCA4-dUT patients had significance worse TTP (HR = 4.35 95% CI 1.77-10.71, p = 0.001) and OS (HR = 4.27, 95% CI 1.12-16.35, p = 0.022) compared to SMARCA4-dNSCLC patients. SMARCA4-dUT histologic type, stage II/III, R1/2 resection and lymphovascular invasion were independent poor prognostic predictors for both TTP and OS. There were 8 patients who received immunotherapy, the objective response rate was 50%. The SMARCA4-dNSCLC patient with ALK rearrangement was treated with crizotinib as second-line therapy, and achieved stable disease for 9.7 months. CONCLUSION: Patients with SMARCA4-deficient tumors have a high probability of early recurrence after surgery, except for stage I patients. Immunotherapy seems to be a valuable strategy to treat recurrence.

The standard of care for patients with early-stage non-small cell lung cancer (NSCLC) is anatomical lung resection with lymphadenectomy. This multicenter, retrospective, cohort study aimed to identify predictors of 5-year survival in patients after thoracoscopic lobectomy for stage IA NSCLC. The study included 1249 patients who underwent thoracoscopic lobectomy for stage IA NSCLC between 17 April 2007, and December 28, 2016. The 5-year survival rate equaled 77.7%. In the multivariate analysis, higher age (OR, 1.025, 95% CI: 1.002 to 1.048; p = 0.032), male sex (OR, 1.410, 95% CI: 1.109 to 1.793; p = 0.005), chronic obstructive pulmonary disease (OR, 1.346, 95% CI: 1.005 to 1.803; p = 0.046), prolonged postoperative air leak (OR, 2.060, 95% CI: 1.424 to 2.980; p < 0.001) and higher pathological stage (OR, 1.271, 95% CI: 1.048 to 1.541; p = 0.015) were related to the increased risk of death within 5 years after surgery. Lobe-specific mediastinal lymph node dissection (OR, 0.725, 95% CI: 0.548 to 0.959; p = 0.024) was related to the decreased risk of death within 5 years after surgery. These findings provide valuable insights for clinical practice and may contribute to improving the quality of treatment of early-stage NSCLC.
RESUMO
OBJECTIVES: Coronavirus disease 2019 (COVID-19) can irreversibly damage the lungs and could possibly increase the risk of surgical treatment of lung cancer. The study aimed to assess the relationship between preoperative COVID-19 and complications and early outcomes of lung cancer surgery. METHODS: This single-center cohort study included 444 patients who underwent lobectomy or segmentectomy for primary lung cancer from January 1, 2019 to December 31, 2021. The exclusion criteria were pneumonectomy, extended resection, and wedge resection. The groups of patients with (n = 72) and without (n = 372) the history of COVID-19 prior to surgery were compared. The groups were similar in terms of distribution of baseline, surgical and histopathological characteristics. The primary endpoint was the incidence of postoperative complications. Secondary endpoints were outcomes at discharge and at 90 days. RESULTS: The incidence of postoperative complications did not differ between the groups of patients with and without COVID-19 history (30.6% vs 29.3%, p = 0.831). Outcomes at discharge and at 90 days after surgery did not differ between the groups. Among the patients with and without prior COVID-19, 97.2 and 99.5% were alive at discharge (p = 0.125), and 97.2% and 98.1% ninety days after surgery (p = 0.644), respectively. Patients with COVID-19 history more often required re-drainage (6.9% v 2.2%, p = 0.044) and reoperation (5.6 v 1.3%, p = 0.042). CONCLUSIONS: COVID-19 history is not related to the general incidence of complications, outcomes at discharge from the hospital, and at 90-days after surgery.

BACKGROUND: The optimal sequence and combination of surgery, chemotherapy and radiotherapy in patients with N2 non-small cell lung cancer (NSCLC) remain undefined. The aim of our study was to compare two treatment options for N2 NSCLC-induction therapy with subsequent surgery versus upfront surgery with adjuvant treatment. METHODS: We retrospectively reviewed 405 patients with N2 disease in two centers, between January 2010 and December 2016. They were divided into two groups: the Induction Group, composed of patients who received neoadjuvant chemotherapy, and the Upfront surgery Group, composed of patients who underwent surgery as first-line therapy. Propensity score-matched (PSM) analysis was performed, and 52 patients were included in each group. Primary endpoints were: recurrence, overall survival (OS) and disease-free survival (DFS). RESULTS: After the PSM, no differences were observed in general characteristics, perioperative results, rates and severity of complications, and histopathology results. Seventeen patients (32.7%) of the induction group and 21 (40.4%) of the upfront surgery group had mediastinal lymph nodal involvement with skipping (p = 0.415). Recurrence rate was not different between the two groups (57.7% vs 50.0%, p = 0.478). No differences were observed in terms of OS (40.98 ± 35.78 vs 37.0 ± 40.69 months, p = 0.246) and DFS (29.67 ± 36.01 vs 27.96 ± 40.08 months, p = 0.697). The multivariable analysis identified the pT stage and skipping lymph node metastasis as independent predictive factors for OS. CONCLUSIONS: Upfront surgery followed by adjuvant therapy does not appear inferior in terms of recurrence, OS and DFS, compared to induction chemotherapy with subsequent surgery.

The outcomes of non-small cell lung cancer surgery are influenced by the quality of lymphadenectomy. This study aimed to evaluate the impact of different energy devices on lymphadenectomy quality and identify additional influencing factors. This secondary analysis of the prospective randomized trial data (clinicaltrials.gov: NCT03125798) compared patients who underwent thoracoscopic lobectomy with the LigaSure device (study group, n = 96) and monopolar device (control group, n = 94). The primary endpoint was the lobe-specific mediastinal lymphadenectomy. Lobe-specific mediastinal lymphadenectomy criteria were met in 60.4% and 38.3% of patients in the study and control groups, respectively (p = 0.002). In addition, in the study group, the median number of mediastinal lymph node stations removed was higher (4 vs. 3, p = 0.017), and complete resection was more often achieved (91.7% vs. 80.9%, p = 0.030). Logistic regression analysis indicated that lymphadenectomy quality was positively associated with the use of the LigaSure device (OR, 2.729; 95% CI, 1.446 to 5.152; p = 0.002) and female sex (OR, 2.012; 95% CI, 1.058 to 3.829; p = 0.033), but negatively associated with a higher Charlson Comorbidity Index (OR, 0.781; 95% CI, 0.620 to 0.986; p = 0.037), left lower lobectomy (OR, 0.263; 95% CI, 0.096 to 0.726; p = 0.010) and middle lobectomy (OR, 0.136; 95% CI, 0.031 to 0.606, p = 0.009). This study found that using the LigaSure device can improve the quality of lymphadenectomy in lung cancer patients and also identified other factors that affect the quality of lymphadenectomy. These findings contribute to improving lung cancer surgical treatment outcomes and provide valuable insights for clinical practice.
