BMC Pulm Med 2024; 24:39. [PMID: 38233903 PMCID: PMC10795229 DOI: 10.1186/s12890-024-02858-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Accepted: 01/09/2024] [Indexed: 01/19/2024] Open
Abstract
BACKGROUND Clinical guidelines recommend a preoperative forced expiratory volume in one second (FEV1) of > 2 L as an indication for left or right pneumonectomy. This study compares the safety and long-term prognosis of pneumonectomy for destroyed lung (DL) patients with FEV1 ≤ 2 L or > 2 L. METHODS A total of 123 DL patients who underwent pneumonectomy between November 2002 and February 2023 at the Department of Thoracic Surgery, Beijing Chest Hospital were included. Patients were sorted into two groups: the FEV1 > 2 L group (n = 30) or the FEV1 ≤ 2 L group (n = 96). Clinical characteristics and rates of mortality, complications within 30 days after surgery, long-term mortality, occurrence of residual lung infection/tuberculosis (TB), bronchopleural fistula/empyema, readmission by last follow-up visit, and modified Medical Research Council (mMRC) dyspnea scores were compared between groups. RESULTS A total of 96.7% (119/123) of patients were successfully discharged, with 75.6% (93/123) in the FEV1 ≤ 2 L group. As compared to the FEV1 > 2 L group, the FEV1 ≤ 2 L group exhibited significantly lower proportions of males, patients with smoking histories, patients with lung cavities as revealed by chest imaging findings, and patients with lower forced vital capacity as a percentage of predicted values (FVC%pred) (P values of 0.001, 0.027, and 0.023, 0.003, respectively). No significant intergroup differences were observed in rates of mortality within 30 days after surgery, incidence of postoperative complications, long-term mortality, occurrence of residual lung infection/TB, bronchopleural fistula/empyema, mMRC ≥ 1 at the last follow-up visit, and postoperative readmission (P > 0.05). CONCLUSIONS As most DL patients planning to undergo left/right pneumonectomy have a preoperative FEV1 ≤ 2 L, the procedure is generally safe with favourable short- and long-term prognoses for these patients. Consequently, the results of this study suggest that DL patient preoperative FEV1 > 2 L should not be utilised as an exclusion criterion for pneumonectomy.

Abstract
BACKGROUND To create a combined variable integrating both ventilation and perfusion as measured by preoperative dual-energy computed tomography (DECT), compare the results with predicted postoperative (PPO) lung function as estimated using conventional methods, and assess agreement with actual postoperative lung function. METHODS A total of 33 patients with lung cancer who underwent curative surgery after DECT and perfusion scan were selected. Ventilation and perfusion values were generated from DECT data. In the "combined variable method," these two variables and clinical variables were linearly regressed to estimate PPO lung function. Six PPO lung function parameters (segment counting, perfusion scan, volume analysis, ventilation map, perfusion map, and combined variable) were compared with actual postoperative lung function using an intraclass correlation coefficient (ICC). RESULTS The segment counting method produced the highest ICC for forced vital capacity (FVC) at 0.93 (p < 0.05), while the segment counting and perfusion map methods produced the highest ICC for forced expiratory volume in 1 second (FEV1 ; both 0.89, p < 0.05). The highest ICC value when using the combined variable method was for FEV1 /FVC (0.75, p < 0.05) and diffusing capacity of the lung for carbon monoxide (DLco; 0.80, p < 0.05) when using the perfusion map method. Overall, the perfusion map and ventilation map provided the best performance, followed by volume analysis, segment counting, perfusion scan, and the combined variable. CONCLUSIONS Use of DECT image processing to predict postoperative lung function produced better agreement with actual postoperative lung function than conventional methods. The combined variable method produced ICC values of 0.8 or greater for FVC and FEV1 .

Abstract
Rationale: Global Lung Function Initiative (GLI) Global spirometry reference equations were recently derived to offer a "race-neutral" interpretation option. The impact of transitioning from the race-specific GLI-2012 to the GLI Global reference equations is unknown. Objectives: Describe the direction and magnitude of changes in predicted lung function measurements in a population of diverse race and ethnicity using GLI Global in place of GLI-2012 reference equations. Methods: In this multicenter cross-sectional study using a large pulmonary function laboratory database, 109,447 spirometry tests were reanalyzed using GLI Global reference equations and compared with the existing GLI-2012 standard, stratified by self-reported race and ethnicity. Measurements and Main Results: Mean FEV1 and FVC percent predicted increased in the White and Northeast Asian groups and decreased in the Black, Southeast Asian, and mixed/other race groups. The prevalence of obstruction increased by 9.7% in the White group, and prevalences of possible restriction increased by 51.1% and 37.1% in the Black and Southeast Asian groups, respectively. Using GLI Global in a population with equal representation of all five race and ethnicity groups altered the interpretation category for 10.2% of spirometry tests. Subjects who self-identified as Black were the only group with a relative increase in the frequency of abnormal spirometry test results (32.9%). Conclusions: The use of GLI Global reference equations will significantly impact spirometry interpretation. Although GLI Global offers an innovative approach to transition from race-specific reference equations, it is important to recognize the continued need to place these data within an appropriate clinical context.

Abstract
INTRODUCTION Declining cancer surgery represents a conflict between patients' rights to autonomy and providers' perspectives of best practice. We hypothesize that, among patients with nonmetastatic lung cancer, patient demographics would be associated with different rates of declination of lung cancer surgery. METHODS Patients with nonmetastatic lung cancer from 2004 to 2018 in the National Cancer Database were identified. Patients were categorized into two groups based on surgical treatment: surgical resection and declined surgery. Patient characteristics were compared using bivariate and multivariate models to identify factors associated with surgical declination. Additionally, we performed subgroup analyses of cT1N0M0 patients with no comorbidities. Survival analysis done using multivariate cox analysis and Kaplan-Meier survival analysis. RESULTS 478,757 patients were identified. In a multivariate model, declining surgery was associated with increased age (odds ratio 1.09, 1.09-1.10), non-Hispanic Black race (odds ratio 1.95, 1.73-2.21), nonprivate insurance, and lower Socioeconomic Status. In a subgroup of cT1N0M0 patients with no comorbidities, declining surgery was associated with increasing age, non-Hispanic Black race, nonprivate insurance, and socioeconomic status. Patient's that declined surgery demonstrated lower overall survival when compared to patients that underwent surgical resection (5 y overall survival: declined surgery 40% versus underwent resection 72%, P < 0.001). CONCLUSIONS Although early-stage lung cancer is potentially curable, many patients decline guideline-based surgery, and have worse overall survival. There are social and economic factors associated with patients declining lung cancer surgery. Providers have an ethical responsibility to understand the basis of patient's decision to decline recommended surgery and address endemic disparities related to race and access to care.

Association of Preoperative Lung Function with Complications after Lobectomy Using Race-Neutral and Race-Specific Normative Equations. Ann Am Thorac Soc 2024; 21:38-46. [PMID: 37796618 PMCID: PMC10867917 DOI: 10.1513/annalsats.202305-396oc] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Accepted: 10/04/2023] [Indexed: 10/07/2023] Open
Abstract
Rationale: Pulmonary function testing (PFT) is performed to aid patient selection before surgical resection for non-small cell lung cancer (NSCLC). The interpretation of PFT data relies on normative equations, which vary by race, but the relative strength of association of lung function using race-specific or race-neutral normative equations with postoperative pulmonary complications is unknown. Objectives: To compare the strength of association of lung function, using race-neutral or race-specific equations, with surgical complications after lobectomy for NSCLC. Methods: We studied 3,311 patients who underwent lobectomy for NSCLC and underwent preoperative PFT from 2001 to 2021. We used Global Lung Function Initiative equations to generate race-specific and race-neutral normative equations to calculate percentage predicted forced expiratory volume in 1 second (FEV1%). The primary outcome of interest was the occurrence of postoperative pulmonary complications within 30 days of surgery. We used unadjusted and race-adjusted logistic regression models and least absolute shrinkage and selection operator analyses adjusted for relevant comorbidities to measure the association of race-specific and race-neutral FEV1% with pulmonary complications. Results: Thirty-one percent of patients who underwent surgery experienced pulmonary complications. Higher FEV1, whether measured with race-neutral (odds ratio [OR], 0.98 per 1% change in FEV1% [95% confidence interval (CI), 0.98-0.99]; P < 0.001) or race-specific (OR, 0.98 per 1% change in FEV1% [95% CI, 0.98-0.98]; P < 0.001) normative equations, was associated with fewer postoperative pulmonary complications. The area under the receiver operator curve for pulmonary complications was similar for race-adjusted race-neutral (0.60) and race-specific (0.60) models. Using least absolute shrinkage and selection operator regression, higher FEV1% was similarly associated with a lower rate of pulmonary complications in race-neutral (OR, 0.99 per 1% [95% CI, 0.98-0.99]) and race-specific (OR, 0.99 per 1%; 95% CI, 0.98-0.99) models. The marginal effect of race on pulmonary complications was attenuated in all race-specific models compared with all race-neutral models. Conclusions: The choice of race-specific or race-neutral normative PFT equations does not meaningfully affect the association of lung function with pulmonary complications after lobectomy for NSCLC, but the use of race-neutral equations unmasks additional effects of self-identified race on pulmonary complications.

Clin Lung Cancer 2023; 24:621-630.

Abstract
OBJECTIVES Based on previous studies, single-photon emission computed tomography/computed tomography (SPECT/CT) has been proven more accurate and reproducible than planar lung perfusion scintigraphy to assess lobar perfusion. However, the impact of 3D-quantitated SPECT/CT on intended management in functionally marginal candidates for pulmonary resection is unknown. The evaluation of this impact was the main aim of this study. METHODS Consecutive candidates for lung resection underwent preoperative evaluation according to ERS/ESTS Algorithm and underwent preoperative lung perfusion imaging. The lobar contribution to the total lung perfusion was estimated using established planar scintigraphic methods and 3-dimensional quantitative SPECT/CT method (CT Pulmo3D and xSPECT-Quant, Siemens). The difference in estimated lobar perfusion with resulting changes in predicted postoperative (ppo) lung function and extent of lung resection were analyzed to reveal possible changes in operability. In-hospital outcome was assessed. RESULTS One hundred twenty patients (46 females) were enrolled. The mean age (±SD) of patients was 68 ± 9 years, target lesions were in upper lobes in 57.7% and in lower lobes in 33.5%. The median FEV1 (forced expiratory volume in 1 second) was 70.5% (IQR 52-84) and median DLCO (diffusion capacity of lung for carbon monoxide) was 56.6% [47.1-67.4]. The planar posterior oblique method, compared to 3D-quantitated SPECT/CT, underestimated the perfusion of upper lobes by a median difference of 5% (right [2-9], left [2.5-8]; P = <.0001), while it overestimated the perfusion of lower lobes (left by 4% [2-7], right by 6% [2-9]; P = <.0001). In contrast to planar scintigraphy-based evaluation, 4 patients (3.3%), all with upper lobe lesions, were classified as inoperable when 3D-quantitated SPECT/CT was used for calculation of the ppo lung function. CONCLUSIONS In selected patients with upper lobe lesions, 3D-quantitated SPECT/CT would have changed the treatment strategy from operable to inoperable. Importantly, postoperative mortality in this particular subgroup was disproportionally high. 3D-quantitated SPECT/CT shall be further evaluated as it might improve preoperative risk stratification in functionally marginal candidates.

Abstract
A cardiopulmonary exercise test (CPET) is essential for lung resection. However, performing a CPET can be challenging. This study aimed to develop a machine learning model to estimate maximal oxygen consumption (VO2max) using data collected through a patch-type single-lead electrocardiogram (ECG) monitoring device in candidates for lung resection. This prospective, single-center study included 42 patients who underwent a CPET at a tertiary teaching hospital from October 2021 to July 2022. During the CPET, a single-lead ECG monitoring device was applied to all patients, and the results obtained from the machine-learning algorithm using the information extracted from the ECG patch were compared with the CPET results. According to the Bland-Altman plot of measured and estimated VO2max, the VO2max values obtained from the machine learning model and the FRIEND equation showed lower differences from the reference value (bias: -0.33 mL·kg-1·min-1, bias: 0.30 mL·kg-1·min-1, respectively). In subgroup analysis, the developed model demonstrated greater consistency when applied to different maximal stage levels and sexes. In conclusion, our model provides a closer estimation of VO2max values measured using a CPET than existing equations. This model may be a promising tool for estimating VO2max and assessing cardiopulmonary reserve in lung resection candidates when a CPET is not feasible.

Abstract
Aerobic, or endurance, exercise is an energy requiring process supported primarily by energy from oxidative adenosine triphosphate synthesis. The consumption of oxygen and production of carbon dioxide in muscle cells are dynamically linked to oxygen uptake (V̇O2) and carbon dioxide output (V̇CO2) at the lung by integrated functions of cardiovascular, pulmonary, hematologic, and neurohumoral systems. Maximum oxygen uptake (V̇O2max) is the standard expression of aerobic capacity and a predictor of outcomes in diverse populations. While commonly limited in young fit individuals by the capacity to deliver oxygen to exercising muscle, (V̇O2max) may become limited by impairment within any of the multiple systems supporting cellular or atmospheric gas exchange. In the range of available power outputs, endurance exercise can be partitioned into different intensity domains representing distinct metabolic profiles and tolerances for sustained activity. Estimates of both V̇O2max and the lactate threshold, which marks the upper limit of moderate-intensity exercise, can be determined from measures of gas exchange from respired breath during whole-body exercise. Cardiopulmonary exercise testing (CPET) includes measurement of V̇O2 and V̇CO2 along with heart rate and other variables reflecting cardiac and pulmonary responses to exercise. Clinical CPET is conducted for persons with known medical conditions to quantify impairment, contribute to prognostic assessments, and help discriminate among proximal causes of symptoms or limitations for an individual. CPET is also conducted in persons without known disease as part of the diagnostic evaluation of unexplained symptoms. Although CPET quantifies a limited sample of the complex functions and interactions underlying exercise performance, both its specific and global findings are uniquely valuable. Some specific findings can aid in individualized diagnosis and treatment decisions. At the same time, CPET provides a holistic summary of an individual's exercise function, including effects not only of the primary diagnosis, but also of secondary and coexisting conditions.

Abstract
PURPOSE Video-assisted thoracoscopic surgery (VATS) has changed the surgical approach to non-small cell lung cancer (NSCLC) dramatically. The current study compares the outcomes of older and younger patients who underwent VATS lobectomy for NSCLC. METHODS In total, 424 eligible patients with pathological stage I NSCLC underwent VATS lobectomy between 2007 and 2017. Patients were classified into two groups (< 75 and ≥ 75 years old), after which propensity score-matching was performed. RESULTS After matching, 143 patients were identified. No significant difference in postoperative complication rates was observed; however, the ≥ 75-year-old group had a longer postoperative hospital stay (p = 0.001). The 5-year overall survival, relapse-free survival, and lung cancer-specific survival rates of the < 75- and ≥ 75-year-old groups were 87.1% vs. 85.6% (p = 0.537), 82.1% vs. 79.0% (p = 0.531), and 93.5% vs. 92.7% (p = 0.832), respectively. CONCLUSION Despite the longer postoperative recovery following VATS lobectomy, the short- and long-term outcomes of older patients did not differ from those of younger patients. Thus, for early-stage NSCLC, older age alone was not a negative factor for lobectomy performed via minimally invasive surgery. Naturally, the systemic condition of this population must be evaluated carefully before surgery.

Abstract
BackgroundThe aim of this study was to evaluate the feasibility and safety of simultaneous bilateral video-assisted thoracic surgery (VATS) for the treatment of bilateral pulmonary lesions.MethodsThe data of 11 patients who received simultaneous bilateral pulmonary surgery using VATS in the Department of Thoracic Surgery of The Third Affiliated Hospital of Naval Medical University between January 2016 and August 2021 were retrospectively analyzed.ResultsThe cases of four male and seven female patients, with a mean age of 57.54 ± 8.37 years (range, 44-67 years), were reviewed. Nonanatomic wedge resection, pulmonary segmentectomy or lobectomy via VATS were performed depending on each patient’s situation. Mean 1 second forced expiratory volume (FEV1) was 2.55 ± 0.66 L(range, 1.49-3.88 L), mean intraoperative bleeding volume was 91.81 ± 49.56 mL(range, 30-150 mL), mean operating time was 273.72 ± 68.98 min(range, 132-390 min), and mean drainage duration was 5.27 ± 3.60 days(range, 2-14 days), with a mean total drainage volume of 1,515.90 ± 772.75 mL(range, 530-3,225 mL). Only one postoperative complication (air leakage) occurred, with an overall complication rate of 9.09%. The mean postoperative hospital stay was 8.81 ± 3.60 days (range, 5-18 days), and the mean total cost of hospitalization was 67,054.53 ± 20,896.49 RMB (range, 47,578.45-123,530.8 RMB).ConclusionsSimultaneous bilateral pulmonary surgery using VATS for the treatment of bilateral pulmonary lesions is safe and feasible and can therefore be considered after strict preoperative evaluation of the patient.

Abstract
BACKGROUND The incidence of multiple primary lung cancer (MPLC) in China is 0.52%-2.45%. Most primary lung cancer cases have reported two lesions or three in rare cases. We report a rare case of bilateral simultaneous multiple primary lung adenocarcinoma of four different genotypes.
CASE SUMMARY A 58-year-old woman was admitted to our hospital on June 29, 2021, and upon physical examination, four multiple pulmonary nodules were identified in both lungs. Further computed tomography (CT) images revealed the presence of ground glass nodules, predicted to be high-risk cancer lesions by artificial intelligence. With the guidance of three-dimensional reconstruction of preoperative CT images, the nodules were resected under thoracoscopy. Postoperative pathological investigation revealed that the nodule types were adenocarcinoma in situ, invasive alveolar adenocarcinoma, and microinvasive adenocarcinoma. The excised nodules were further sequenced using high-throughput sequencing (semiconductor sequencing method) of 26 lung cancer genes to confirm that the four lesions were not homologous. The patient was discharged on postoperative day 8, that is, on July 15, 2021. One month later, she returned to the hospital for follow-up and reexamination. Chest CT examination showed that she had recovered well, and no obvious exudation and effusion were found in both pleural cavities. Evaluation of postoperative pulmonary function showed that her forced vital capacity was 1.40 L (preoperative value, 2.27 L) and forced expiratory volume was 1.24 L (preoperative value, 2.23 L).
CONCLUSION The surgical plan for multiple pulmonary nodules should be carefully considered. For carefully selected patients with concurrently occurring multiple lung nodules in both lungs, sublobectomy is a safe and feasible plan for concurrent bilateral resection of the lesions. Genetic sequencing is necessary for MPLC diagnosis and treatment.

Access to Care Metrics in Stage I Lung Cancer: Improved Access Is Associated with Improved Survival. Ann Thorac Surg 2022; 114:1810-1815. [PMID: 35724700 DOI: 10.1016/j.athoracsur.2022.05.047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2022] [Revised: 03/20/2022] [Accepted: 05/08/2022] [Indexed: 11/24/2022]
Abstract
BACKGROUND Equitable access to care is a critical component of comprehensive surgical lung cancer management. Despite this, quality measures (QMs) assessing pre-operative access to care are lacking. We determined several pre-operative QMs based on contemporary treatment guidelines and hypothesized that poor access to care was associated with worse outcomes. METHODS We performed a retrospective cohort study using a uniquely compiled Veterans Health Administration (VHA) dataset of patients with clinical stage I non-small cell lung cancer (NSCLC) receiving surgical treatment (2006-2016). We defined four QMs that patients with clinical stage I NSCLC should routinely meet in the pre-operative period: timely surgery, positron emission tomography imaging, appropriate smoking management, and pulmonary function testing. We assessed the relationship between meeting these QMs and various short- and long-term outcomes. RESULTS Among 9,749 Veterans undergoing surgery for clinical stage I NSCLC, 3,371 (34.6%) met all QMs. Factors associated with lower likelihood of meeting all QMs included black race (adjusted odds ratio [aOR] 0.744, 95% CI 0.652-0.848), higher area deprivation index score (e.g., quartile 5 vs. 1, aOR 0.747, 0.647-0.863), and increased distance to hospital (e.g., quartile 5 vs. 1, aOR 0.700, 0.605-0.811). Adherence to all QMs was associated with significantly lower likelihood of post-operative mortality (aOR 0.623, 0.433-0.896) and improved overall survival (adjusted hazard ratio [aHR] 0.897, 0.844-0.954). CONCLUSIONS Inadequate access to pre-operative care is associated with worse short- and long-term outcomes in clinical stage I NSCLC. Future VHA policy measures should focus on providing more equitable guideline-concordant care to Veterans.

Abstract
OBJECTIVES To evaluate the surgical outcomes after surgery in patients with stage I lung cancer and idiopathic interstitial pneumonia (IIP). MATERIAL AND METHODS This retrospective cohort study was conducted in 2131 patients with clinical stage I non-small-cell lung cancer (NSCLC) who underwent pulmonary resection between 2009 and 2018. Based on computed tomography (CT) findings, 233 patients had IIP. Lobectomy was performed in 180 patients with IIP and 1227 patients without IIP. Surgical outcomes, recurrence sites, and cause of death were investigated. In addition, we measured the distance between the tumor and hilum in patients with IIP and assessed the feasibility of sublobar resection. RESULTS The overall survival and cancer-specific survival of patients with IIP were significantly poorer than those of non-IIP patients. The five-year overall survival rates of patients with clinical stage IA/IB lung cancer with and without IIP were 58.1%/47.3% and 88.8%/68.9%, respectively. Furthermore, 9.4% of patients with IIP and 0.9% of patients without IIP died from respiratory-related causes within 2 years after surgery. Multivariate analyses revealed that volume capacity <80% (odds ratio: 3.259), usual interstitial pneumonia pattern by CT finding (odds ratio: 1.891), and nodal metastasis (odds ratio: 3.304) were prognostic factors for overall survival in patients with IIP. Unexpected nodal metastases were observed in 22.3% of patients with IIP. By CT judgment, sublobar resection was not feasible in 68% of patients with IIP who underwent lobectomy. CONCLUSIONS The overall survival of patients with early NSCLC after pulmonary resection with IIP was poor; this is related to the high prevalence of cancer-specific and respiratory-related deaths. Sublobar resection is not always feasible, the procedure on patients with IIP should be selected carefully according to the characteristics of each case. Nodal dissection should be performed to evaluate for metastasis, regardless of the extent of lung resection.

Abstract
Background Patients with high-risk (HR) operable non-small cell lung cancer (NSCLC) may have unique prognostic factors. This study aimed to evaluate surgical outcomes in HR patients and to investigate prognostic factors in HR patients versus standard-risk (SR) patients. Methods In total, 471 consecutive patients who underwent curative lung resection for NSCLC between January 2012 and December 2017 were identified and reviewed retrospectively. Patients were classified into HR (n=77) and SR (n=394) groups according to the American College of Surgeons Oncology Group criteria (Z4099 trial). Postoperative complications were defined as those of grade 2 or higher by the Clavien-Dindo classification. Results The HR group comprised more men and older patients, had poorer lung function, and had more comorbidities than the SR group. The patients in the HR group also experienced more postoperative complications (p≤0.001). More HR patients died without disease recurrence. The postoperative complication rate was the only significant prognostic factor in multivariable Cox regression analysis for HR patients but not SR patients. HR patients without postoperative complications had a survival rate similar to that of SR patients. Conclusion The overall postoperative survival of HR patients with NSCLC was more strongly affected by postoperative complications than by any other prognostic factor. Care should be taken to minimize postoperative complications, especially in HR patients.

The impact of pulmonary function tests on early postoperative complications in open lung resection surgery: an observational cohort study. Sci Rep 2022; 12:1277.

Abstract
We investigated whether pulmonary function tests (PFTs) can predict pulmonary complications and if they are, to find new cutoff values in current open lung resection surgery. In this observational study, patients underwent open lung resection surgery at a tertiary hospital were analyzed (n = 1544). Various PFTs were tested by area under the receiver-operating characteristic curve (AUCROC) to predict pulmonary complications until 30 days postoperatively. In results, PFTs were generally not effective to predict pulmonary complications (AUCROC: 0.58-0.66). Therefore, we could not determine new cutoff values, and used previously reported cutoffs for post-hoc analysis [predicted postoperative forced expiratory volume in one second (ppoFEV1) < 40%, predicted postoperative diffusing capacity for carbon monoxide (ppoDLCO) < 40%]. In multivariable analysis, old age, male sex, current smoker, intraoperative transfusion and use of inotropes were independent risk factors for pulmonary complications (model 1: AUCROC 0.737). Addition of ppoFEV1 or ppoDLCO < 40% to model 1 did not significantly increase predictive capability (model 2: AUCROC 0.751, P = 0.065). In propensity score-matched subgroups, patients with ppoFEV1 or ppoDLCO < 40% showed higher rates of pulmonary complications [13% (21/160) vs. 24% (38/160), P = 0.014], but no difference in in-hospital mortality [3% (8/241) vs. 6% (14/241), P = 0.210] or mean survival duration [61 (95% CI 57-66) vs. 65 (95% CI 60-70) months, P = 0.830] compared to patients with both > 40%. In conclusion, PFTs themselves were not effective predictors of pulmonary complications. Decision to proceed with surgical resection of lung cancer should be made on an individual basis considering other risk factors and the patient's goals.

Abstract
Lung (bronchial) cancer is the leading cause of cancer-related death in Western countries today. Thoracic surgery represents a major therapeutic strategy and the various advances made in recent years have made it possible to develop less and less invasive techniques. That said, the postoperative period may be lengthy, post-surgical approaches need to be more precisely codified, and it matters that the different interventions involved be supported by sound scientific evidence. To date, however, there exists no evidence that preventive postoperative admission to intensive care is beneficial for patients having undergone lung resection surgery without immediate complications. A stratification of the risk of complications taking into consideration the patient's general state of health (e.g., nutritional status, degree of autonomy, etc.), comorbidities and type of surgery could be a useful predictive tool regarding the need for postoperative intensive care. However, serious post-operative complications remain relatively frequent and post-operative management of these intensive care patients is liable to become complex and long-lasting. In the aftermath of the validation of "enhanced recovery after surgery" (ERAS) in thoracic surgery, new protocols are needed to optimize management of patients having undergone pulmonary resection. This article focuses on the main postoperative complications and more broadly on intensive care patient management following thoracic surgery.

Abstract
Enhanced Recovery After Surgery (E.R.A.S.) is a multimodal, evidence-based and patient-centered pathway designed to minimize surgical stress, enhancing recovery and improving perioperative outcomes. However, considering that the potential clinical implication of E.R.A.S. on patients undergoing video-assisted thoracic surgery (V.A.T.S.) has not properly defined, we proposed to implement our minimally invasive program with a specific clinical pathway able to enhance recovery after lung resection. Aim of this study was to assess the impact of this integrated program of Enhanced Pathway of Care (E.P.C.) in Uniportal V.A.T.S. patients undergoing lung resection, in terms of efficiency and safety. We conducted a retrospective, observational study enrolling patients undergoing uniportal V.A.T.S. resections from January 2015 to May 2020. Two groups were created: pre-E.P.C. and E.P.C. Propensity score matching analysis was performed to evaluate length of stay (LOS), postoperative cardiopulmonary complications (CPC) and readmission rate (READM). We analyzed 1167 patients (E.P.C. group: 182; pre-E.P.C. group: 985). E.P.C. group has a mean LOS shorter compared to pre-E.P.C. group (3.13 vs 4.19 days, p < 0.0001) without increasing on CPC (E.P.C. 12% vs pre-E.P.C. 11%, p = 0.74) and READM rate (E.P.C. 1.6% vs pre-E.P.C. 4.9%, p = 0.07). In particular, the LOS was shortened in the E.P.C. patients submitted to lobectomy, segmentectomy and wedge resection. Moreover, the three subgroups had similar CPC and READM rates for E.P.C. and control patients. In conclusion, this study demonstrated the benefits and safety of E.P.C. program showing a reduction of LOS for patients undergoing uniportal V.A.T.S. resection.

Abstract
PURPOSE To evaluate the predictive value of stair climbing test (SCT) on postoperative complications in lung cancer patients with limited pulmonary function. METHODS A total of 727 hospitalized lung cancer patients with limited pulmonary function were retrospectively reviewed. Included in the cohort were 424 patients who underwent SCT preoperatively. Patients were grouped according to general condition, past medical history, surgical approach, pulmonary function test, and SCT results. Comparison of the postoperative cardiopulmonary complication rates was made and independent risk factors were identified. RESULTS A total of 89 cardiopulmonary-related complications occurred in 69 cases, accounting for 16.3% of the entire cohort. The postoperative cardiopulmonary complication rates were significantly different between groups stratified by smoking index, percentage of forced expiratory volume in one second, percentage of diffusion capacity for carbon monoxide, SCT results, excision extension, and anesthetic duration (p <0.05). Multivariate analysis showed that only height achieved (p <0.001), changes in heart rate (∆HR; p <0.001), and excision extension (p = 0.006) were independent risk factors for postoperative cardiopulmonary complications. CONCLUSIONS The SCT could be used as a preoperative screening method for lung cancer patients with limited pulmonary function. For those patients who could only climb less than 6 floors or had ∆HR >30 bpm in the test, sublobar resection should be selected to reduce the postoperative cardiopulmonary complication rate.

Abstract
INTRODUCTION Failure to rescue (FTR), defined as the mortality rate among patients suffering from postoperative complications, is considered an indicator of the quality of surgical care. The aim of this study was to investigate the risk factors associated with FTR after anatomical lung resections. METHOD Patients undergoing anatomical lung resection at our center between 1994 and 2018 were included in the study. Postoperative complications were classified as minor (grade I and II) and major (grade IIIA to V), according to the standardized classification of postoperative morbidity. Patients who died after a major complication were considered FTR. A stepwise logistic regression model was created to identify FTR predictors. Independent variables included in the multivariate analysis were age, body mass index, cardiac, renal, and cerebrovascular comorbidity, ppoFEV1%, VATS approach, extended resection, pneumonectomy, and reintervention. A non-parametric ROC curve was constructed to estimate the predictive capacity of the model. RESULTS A total of 2.569 patients were included, of which 223 (8.9%) had major complications and 49 (22%) could not be rescued. Variables associated with FTR were: age (OR: 1.07), history of cerebrovascular accident (OR: 3.53), pneumonectomy (OR: 6.67), and reintervention (OR: 12.26). The area under the ROC curve was 0.82 (95% CI: 0.77-0.88). CONCLUSIONS Overall, 22% of patients with major complications following anatomical lung resection in this series did not survive until discharge. Pneumonectomy and reintervention are the most significant risk factors for FTR.

A Modified Calculation Improves the Accuracy of Predicted Postoperative Lung Function Values in Lung Cancer Patients. Lung 2021; 199:395-402.

Abstract
PURPOSE Preoperative pulmonary function testing is mandatory for non-small cell lung cancer (NSCLC) surgery. The predicted postoperative FEV1 (ppoFEV1) is used for further risk stratification. We compared the ppoFEV1 with the postoperative FEV1 (postFEV1) in order to improve the calculation of the ppoFEV1. METHODS 87 patients voluntarily received an FEV1 assessment 1 year after surgery. ppoFEV1 was calculated according to the Brunelli calculation. Baseline characteristics and surgical procedure were compared in a uni- and multivariate analysis between different accuracy levels of the ppoFEV1. Parameters which remained significant in the multinominal regression analysis were evaluated for a modification of the ppoFEV1 calculation. RESULTS Independent factors for a more inaccurate ppoFEV1 were preoperative active smoking (odds ratio (OR) 4.1, confidence interval (CI) 3.6-6.41; p = 0.01), packyears (OR 4.1, CI 3.6-6.41; p = 0.008), younger age (OR 1.1, CI 1.01-1.12; p = 0.03), and patients undergoing pneumectomy (OR 5.55, CI 1.35-23.6; p = 0.01). For the customized ppoFEV1 we excluded pneumonectomies. For patients < 60 years, an additional lung segment was added to the calculation. ppoFEV1 = preFEV1 × [Formula: see text]. For actively smoking patients with more than 30 packyears we subtracted one lung segment from the calculation ppoFEV1 = PreFEV1 × [Formula: see text]. CONCLUSION We were able to enhance the predictability of the ppoFEV1 with modifications. The modified ppoFEV1 (1.828 l ± 0.479 l) closely approximates the postFEV1 of 1.823 l ± 0.476 l, (0.27%) while the original ppoFEV1 calculation is at 1.78 l ± 0.53 (2.19%). However, if patients require pneumectomy, more complex techniques to determine the ppoFEV1 should be included to stratify risk.

Abstract
Objective To investigate the effect of pulmonary ventilation reserve function on perioperative pulmonary function and postoperative outcome in patients undergoing spinal orthopedic surgery. Methods Ninety patients undergoing spinal orthopedic surgery in our hospital from June 2019 to December 2020 were divided into two groups according to the percentage of preoperative pulmonary reserve function index MVV in the predicted value. Arterial oxygen partial pressure, carbon dioxide partial pressure, oxygenation index (OI), airway plateau pressure (Pplat), and airway resistance (AR) of patients in each group were observed before the start of surgery (T0), at 1 h (T1) and 2 h (T2) after the start of surgery, and at the end of surgery (T3). After the end of surgery, the probability of patient transfer to ICU, time to resume spontaneous breathing, and time to extubation were recorded, and PaO2 and inflammatory factors interleukin-6, procalcitonin, and C-reactive protein of patients were followed up for 1 week. Results In both groups, PaO2 and OI decreased obviously while Pplat and AR increased significantly at T1, T2, and T3, but in Group A, Pplat and AR were markedly lower than those in Group B while PaO2 and OI were notably higher than those in Group B ( p < 0.05). Both time to resume spontaneous breathing and time to extubation in Group B were longer than those in Group A ( p < 0.05). The probability of entering ICU in Group B is higher than that in Group A. Both PaO2 and OI at day 3 after surgery in Group B were lower than those in Group A. While, there is no difference at T2. Conclusion For patients, both intraoperative pulmonary function and time to postoperative resuscitation can be predicted by measuring the preoperative MVV, and long-term prognosis will not be affected by the pulmonary function impairment.

Preoperative evaluation for lung resection in patients with bronchiectasis: should we rely on standard lung function evaluation? Eur J Cardiothorac Surg 2021; 59:1272-1278. [PMID: 33491053 DOI: 10.1093/ejcts/ezaa454] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Revised: 10/24/2020] [Accepted: 11/04/2020] [Indexed: 11/14/2022] Open
Abstract
OBJECTIVES The scant data about non-cystic fibrosis bronchiectasis, including tuberculosis sequelae and impairment of lung function, can bias the preoperative physiological assessment. Our goal was to evaluate the changes in lung function and exercise capacity following pulmonary resection in these patients; we also looked for outcome predictors. METHODS We performed a non-randomized prospective study evaluating lung function changes in patients with non-cystic fibrosis bronchiectasis treated with pulmonary resection. Patients performed lung function tests and cardiopulmonary exercise tests preoperatively and 3 and 9 months after the operation. Demographic data, comorbidities, surgical data and complications were collected. RESULTS Forty-four patients were evaluated for lung function. After resection, the patients had slightly lower values for spirometry: forced expiratory volume in 1 s preoperatively: 2.21 l ± 0.8; at 3 months: 1.9 l ± 0.8 and at 9 months: 2.0 l ± 0.8, but the relationship between the forced expiratory volume in 1 s and the forced vital capacity remained. The gas diffusion measured by diffusing capacity for carbon monoxide did not change: preoperative value: 23.2 ml/min/mmHg ± 7.4; at 3 months: 21.5 ml/min/mmHg ± 5.6; and at 9 months: 21.7 ml/min/mmHg ± 8.2. The performance of general exercise did not change; peak oxygen consumption preoperatively was 20.9 ml/kg/min ± 7.4; at 3 months: 19.3 ml/kg/min ± 6.4; and at 9 months: 20.2 ml/kg/min ± 8.0. Forty-six patients were included for analysis of complications. We had 13 complications with 2 deaths. To test the capacity of the predicted postoperative (PPO) values to forecast complications, we performed several multivariate and univariate analyses; none of them was a significant predictor of complications. When we analysed other variables, only bronchoalveolar lavage with positive culture was significant for postoperative complications (P = 0.0023). Patients who had a pneumonectomy had a longer stay in the intensive care unit (P = 0.0348). CONCLUSIONS The calculated PPO forced expiratory volume in 1 s had an excellent correlation with the measurements at 3 and 9 months; but the calculated PPO capacity for carbon monoxide and the PPO peak oxygen consumption slightly underestimated the 3- and 9-month values. However, none of them was a predictor for complications. Better tools to predict postoperative complications for patients with bronchiectasis who are candidates for lung resection are needed.

Abstract
PURPOSE To evaluate the surgical outcomes of lung cancer patients with idiopathic interstitial pneumonia (IIP) and/or coronary artery disease (CAD). METHODS The subjects of this retrospective study were 2830 patients who underwent surgical resection for lung cancer between 2009 and 2018. Seventy-one patients (2.6%) had both IIP and CAD (FC group). The remaining patients were divided into those with IIP only (group F), those with CAD only (group C), and those without IIP or CAD (group N). We compared mortality and overall survival (OS) among the groups. RESULTS The 90-day mortality and OS were poorer in group FC than in groups C and N, but equivalent to those in group F. Multivariate analyses revealed that IIP (odds ratio [OR] 3.163; p = 0.001) and emphysema (2.588; p = 0.009) were predictors of 90-day mortality. IIP (OR 2.991, p < 0.001), diabetes (OR 1.241, p = 0.043), and a history of other cancers (OR 1.347, p = 0.011) were all predictors of OS. CONCLUSIONS Short-term and long-term mortality after lung cancer surgery were not dependent on coexistent CAD but were related to IIP. Thus, computed tomography (CT) should be done preoperatively to check for IIP, which is a risk factor for surgical mortality.

Abstract
OBJECTIVES Postoperative pulmonary function is difficult to predict accurately, because it changes from the time of the operation and is also affected by various factors. The objective of this study was to assess the accuracy of predicted postoperative forced expiratory volume in 1 s (FEV1) at different postoperative times after lobectomy. METHODS This retrospective study enrolled 104 patients who underwent lobectomy by video-assisted thoracic surgery. Pulmonary function tests were performed preoperatively and postoperatively at 3, 6 and 12 months. We investigated time-dependent changes in FEV1. In addition, the ratio of measured to predicted postoperative FEV1 calculated by the subsegmental method was evaluated to identify the factors associated with variations in postoperative FEV1. RESULTS Compared with the predicted postoperative FEV1, the measured postoperative FEV1 was 8% higher at 3 months, 11% higher at 6 months and 13% higher at 12 months. The measured postoperative FEV1 significantly increased from 3 to 6 months (P = 0.002) and from 6 to 12 months (P = 0.015) after lobectomy resected lobe, smoking history and body mass index were significant factors associated with the ratio of measured to predicted postoperative FEV1 at 12 months (P < 0.001, P = 0.036 and P = 0.025, respectively). CONCLUSIONS Postoperative FEV1 increased up to 12 months after lobectomy by video-assisted thoracic surgery. The predicted postoperative pulmonary function was underestimated after 3 months, particularly after lower lobectomy.

Abstract
Background Lung cancer patients with chronic obstructive pulmonary disease (COPD) are considered a high-risk population to receive radical surgical treatment due to the high incidence of cardiopulmonary complications. The aim of this study was to evaluate the clinical factors associated with postoperative complications in primary lung cancer patients with moderate to extremely severe grades of COPD. Methods From December 2015 to June 2020, 138 patients with moderate to extremely severe COPD who underwent video-assisted thoracoscopic surgery (VATS) lung cancer resection (lobectomy or sublobar resection) were retrospectively reviewed. Patients' postoperative complications were collected from clinical records. Clinical factors (such as COPD severity or surgical approaches, etc.) were evaluated to investigate the association with postoperative complications. Results Of the 138 patients included in the study, the mean age was 67 (63-74) years, the mean preoperative forced expiratory volume in one second (FEV1) was 1.33±0.39 L, the mean FEV1% was 51.23% (41.43-60.00%). 33% patients (46/138) had postoperative complications, and no mortality occurred. Univariate analysis revealed that incidence of overall complications (OCs) and respiratory complications (RCs) was markedly higher in extremely severe COPD patients compared to moderate (OCs, P=0.033; RCs, P=0.050) and severe (OCs, P=0.015; RCs, P=0.008) COPD patients, respectively. Multivariate analysis showed that COPD grade was an independent risk factor of RCs (P=0.024). Furthermore, the grades of COPD (moderate, P=0.029; severe, P=0.028; extremely severe, P=0.019) and the surgical procedure (lobectomy or sublobar resection, P=0.043) were independent risk factors for atelectasis, which was the most common postoperative complication. Conclusions The aggravation of COPD was accompanied by an increase in the incidence of respiratory system complications postoperatively, especially atelectasis. For patients with moderate to extremely severe grades of COPD, careful perioperative evaluation should be performed to identify the indicators that influence the surgical choice between lobectomy and sublobar resection.

Abstract
OBJECTIVES Uniportal (U-VATS) pneumonectomy in lung cancer patients remains disputed in terms of oncological outcomes, and has not been compared to open approaches previously. We evaluated U-VATS versus open pneumonectomy at a high-volume centre. METHODS Patients undergoing pneumonectomy for lung cancer between 2014 and 2018 were retrospectively reviewed and divided into two groups based on surgical approach. Propensity-score matching was performed (1:1), and intention-to-treat analysis applied. Overall survival, operative time, intraoperative blood loss, hospital-stay and readmission, pain, time to adjuvant therapy, morbidity and mortality were tested. Statistical analysis was performed using SAS version 9.4 (SAS Institute Inc. NC) RESULTS: 341 patients underwent pneumonectomy; 23 patients with small-cell lung cancer were excluded, thus 318 patients were submitted to surgery by either U-VATS (n = 54) or open (n = 264). After matching, 52 patients were selected from each group. Five patients (9.2%) in the uniportal group required conversion. There was no significant difference in intraoperative outcomes, complication rates, readmission rates or mortality. The U-VATS group experienced significantly shorter hospital stay (mean ± SD; 6.7 ± 2.7 vs 9.1 ± 2.3 days, p < 0.001) and reported less pain postoperatively (p < 0.0001). Adjuvant chemotherapy was initiated sooner after U-VATS (38.1 ± 8.4 vs 50.8 ± 11.5 days, p < 0.0001). Overall survival appeared to be superior in U-VATS when pathology stage was aligned (p = 0.001). CONCLUSIONS Uniportal VATS is a safe and effective alternative approach to open surgery for pneumonectomy in lung cancer. Complications and oncologic outcomes were comparatively similar. U-VATS showed lower postoperative pain, shorter hospital stay and superior overall survival. The study is a preliminary analysis.

Abstract
Background The aim of this study was to investigate the feasibility and safety of simultaneous bilateral thoracoscopic lobectomy and compare perioperative and late outcomes between simultaneous and staged bilateral thoracoscopic lobectomy. Methods Between January 2013 and December 2017, the medical records of patients who underwent bilateral thoracoscopic lobectomy for synchronous bilateral multiple primary lung cancer (SPLC) were reviewed retrospectively. Univariate analysis was used to examine the factors associated with morbidity. Survival was estimated with the Kaplan-Meier method. Results In the simultaneous resection group (n=41) and the staged groups (n=66), 11 and 16 patients underwent postoperative complication, respectively, whereas no significant differences existed between two groups (P=0.850). Univariate analysis showed that preoperative comorbidities (P=0.009), FEV1 <2 L (P=0.001), FEV1% <80% (P=0.036), and the number of pulmonary segments resected ≥9 (P=0.014) were the risk factors to increased simultaneous resection postoperative complication. In addition, simultaneous resection could significantly reduce total cost compared to staged resection (10,854.6±1,998.8 vs. 16,241.4±2,972.8 USD, P<0.001). In long-time outcomes, the patients with simultaneous resection showed better disease-free survival (DFS) than patients with staged resection at 5 years (67.7% vs. 45.9%, P=0.039). In subgroup analysis, simultaneous resection also had a significantly better survival than staged resection in patients with bilateral pure solid lesions or the biggest tumor size >3 cm. Conclusions Bilateral thoracoscopic lobectomy could be a feasible option for SPLC based on appropriate patient selection and careful perioperative management. Meanwhile, simultaneous resection has significantly advantaged in reducing the cost, preventing tumor progression compare to staged resection.

Abstract
OBJECTIVES The American College of Chest Physicians guidelines recommend low-technology exercise tests in the functional evaluation of patients with lung cancer considered for resectional surgery. However, the 6-min walk test (6MWT) is not included, because the data on its clinical value are inconsistent. Our goal was to evaluate the 6MWT in assessing the risk of cardiopulmonary complications in candidates for lung resection. METHODS We performed a retrospective assessment of clinical data and pulmonary function test results in 947 patients, mean age 65.3 (standard deviation 9.5) years, who underwent a single lobectomy for lung cancer. In 555 patients with predicted postoperative values ≤60%, the 6MWT was performed. The 6-min walking distance (6MWD) and the distance-saturation product (DSP), which is the product of the 6MWD in metres, and the lowest oxygen saturation registered during the test were assessed. RESULTS A total of 363 patients with predicted postoperative values <60% and a 6MWT distance (6MWD) ≥400 m or DSP ≥ 350 m% had a lower rate of cardiopulmonary complications than patients with shorter 6MWD or lower DSP values [odds ratio (OR) 0.53, 95% confidence interval (CI) 0.35-0.81] and 0.47 (95% CI 0.30-0.73), respectively. This result was also true for patients with predicted postoperative values <40%, ORs 0.33 (95% CI 0.14-0.79) and 0.25 (95% CI 0.10-0.61), respectively. CONCLUSIONS The 6MWT is useful in the assessment of operative risk in patients undergoing a single lobectomy for lung cancer. It helps to stratify the operative risk, which is lower in patients with 6MWD ≥400 m or DSP ≥350 m% than in patients with a shorter 6MWD or lower DSP values.

Abstract
OBJECTIVE We report our experience with simultaneous localization and thoracoscopic removal for nonpalpable undiagnosed pulmonary nodules. METHODS All patients with nonpalpable lesions requiring video-assisted thoracoscopic surgery (VATS) wedge resection underwent localization of the targets and surgical removal in a hybrid operating room. Lesions were considered nonpalpable if they were small (<1 cm), deep (>1 cm from the surface), subsolid, or located within a dystrophic area. In all cases, intraoperative cone-beam computed tomography was performed for nodule localization and targeting, metal hookwires, or coils were alternatively used for intraoperative marking. RESULTS From April 2016 to November 2019, 39 image-guided VATS (iVATS) were performed. The mean lesion size was 12 ± 6 mm. The mean distance from the deep edge of the lesion to the pleural surface was 24 ± 9 mm. The localization was performed with 20 hookwires and 19 coils. iVATS localization was successful in 36 patients (92.3%). Thirty-seven wedge resections were completed by VATS, 2 (5%) required conversion to thoracotomy. In 9 patients with intraoperative diagnosis of lung cancer, a lobectomy was performed (7 VATS and 2 thoracotomies). Mean length of iVATS localization was 30 ± 13 minutes. Median postoperative length of stay was 4 days (IQR 3 to 5). CONCLUSIONS iVATS seems to be a helpful tool for simultaneous localization and removal of nonpalpable nodules. A versatile approach using different devices seems advisable for the removal of targets in every clinical scenario reducing VATS conversion rate. Future research is required to compare iVATS with traditional preoperative localization techniques.

Abstract
OBJECTIVES To evaluate perioperative risk factors for AF in patients undergoing uniportal VATS pneumonectomy versus open thoracotomy, and to investigate mediastinal lymph nodes dissection (MLND) on the occurrence of AF. METHODS Patients were divided into 2 groups based on the surgical approach: uniportal VATS and open pneumonectomy. Analysis was done using chi-square test. Multiple variables were tested using univariate analysis. A p value ≤ 0.05 was considered statistically significant. RESULTS Three-hundred and forty-one patients underwent pneumonectomy between 2014 and 2018 in Shanghai Pulmonary Hospital. Fifty-eight patients underwent uniportal VATS, and 283 underwent thoracotomies. AF was the most common event observed. The overall occurrence of peri-operative AF was 33/341 (9.67%). In the uniportal, converted, and open group the incidence of AF was: 3/52 (5.76%), 1/6 (16.6%), and 29/283 (10.42%), respectively. Overall, there was no specific surgical technique correlated with increased incidence of AF (p = 0.432). By univariate analysis; large tumor size > 4.5 cm (p < 0.010), operative time (OT) > 125 min (p < 0.002), and greater volume of blood loss (p < 0.001) increased the risk of AF. Additionally, patients who experienced higher post-operative pain (p < 0.002) were more vulnerable to developing AF. Mortality occurred in one AF patient (1/33, 3%). Number of lymph nodes harvested was not related to AF incidence (p = 0.520). CONCLUSIONS Although AF incidence was lower in uniportal group, it was not statistically significant. Large tumor size, long operative time, and increased blood loss were associated with increased risk of perioperative AF. These results need to be confirmed by larger studies.

Abstract
Lung perfusion scintigraphy is done as a part of preoperative evaluation in lung cancer patients for the prediction of postoperative forced expiratory volume in the first second (FEV1). This study was performed to see the accuracy of prediction of postoperative FEV1 by perfusion scintigraphy for patients undergoing lobectomy/pneumonectomy by comparing it with actual postoperative FEV1 obtained by spirometry 4-6 months after surgery. We retrospectively reviewed 50 surgically resected lung cancer patients who underwent preoperative spirometry, lung perfusion study, and postoperative spirometry. Pearson's correlation coefficient was used to evaluate the relationship between predicted postoperative FEV1 (PPO FEV1) by lung perfusion scintigraphy and postoperative actual FEV1 measured by spirometry. Agreement between the two methods was analyzed with Bland-Altman method. The correlation between the PPO FEV1 and actual postoperative FEV1 was statistically significant (r = 0.847, P = 0.000). The correlation was better for pneumonectomy compared to lobectomy (r = 0.930 [P = 0.000] vs. 0.792 [P = 0.000]). The agreement analysis showed a mean difference of -0.0558 with a standard deviation (SD) of 0.284. The limits of agreement vary over a wide range from --0.625 to 0.513 L (mean ± 2 SD) for the entire group. For pneumonectomy, the mean difference was -0.0121 and SD 0.169 with limits of agreement varying between -0.30 L and 0.30 L. For lobectomy, the mean difference was -0.0826 and SD 0.336 with limits of agreement varying between -0.755 L and 0.590 L. Postoperative FEV1 predicted using lung perfusion scintigraphy shows good correlation with actual postoperative FEV1 and shows reasonably good agreement in patients undergoing pneumonectomy. The limits of agreement appear to be clinically unacceptable in patients undergoing lobectomy, where single-photon emission computed tomography (SPECT) or SPECT/CT techniques may improve prediction.

Abstract
OBJECTIVES Acute exacerbation of interstitial pneumonia (AE-IP) is the top cause of 30-day mortality in surgery for lung cancer patients. The general treatment for AE-IP is corticosteroid; however, there are some disadvantages of corticosteroid use after surgery. This study was conducted to report the clinical course of AE-IP after surgery and evaluate the effect of corticosteroid use. METHODS This retrospective study was performed on 337 patients with interstitial pneumonia who underwent surgical resection for lung cancer at our institute between 2009 and 2018. AE-IP were observed in 14 patients (4.2%) and their management and clinical outcome were investigated. RESULTS All patients received methylprednisolone pulse therapy. Six patients (42.9%) became convalescent after pulse therapy and eight (57.1%) died within 90 days after surgery due to lack of therapeutic efficacy. Oxygenation and ground-glass opacities of the survivors improved within 3 days after starting pulse therapy. Patients who responded to the first pulse also responded to the second pulse. Four patients developed complications including two with bronchopulmonary fistulas that may be related to steroid treatment. Even if the corticosteroid was effective, all AE-IP patients died within 1 year after surgery. CONCLUSIONS Corticosteroid therapy is effective for AE-IP after surgery; however, it may lead to severe complications after surgery.

Abstract
外科手术是目前根治非小细胞肺癌(non-small cell lung cancer, NSCLC)的最有效方式。全肺切除作为一种术式被应用于临床中。对于中央型肺癌,袖式肺叶切除术因其术后肺功能丧失少、术后并发症及死亡率低逐渐取代全肺切除术成为主流。然而为保证肿瘤学效果,当其他术式无法完全切除时,全肺切除术式仍是必要的。全肺切除术后主要发生心肺并发症,充分了解全肺切除术后相关并发症能帮助临床医师及时做出诊断,并进一步采取相关措施降低术后并发症对患者的不良影响。充分了解预后相关危险因素可帮助临床医师提前采取措施尽可能规避风险,从而改善患者预后。

Abstract
INTRODUCTION Failure to rescue (FTR), defined as the mortality rate among patients suffering from postoperative complications, is considered an indicator of the quality of surgical care. The aim of this study was to investigate the risk factors associated with FTR after anatomical lung resections. METHOD Patients undergoing anatomical lung resection at our center between 1994 and 2018 were included in the study. Postoperative complications were classified as minor (grade I and II) and major (grade IIIA to V), according to the standardized classification of postoperative morbidity. Patients who died after a major complication were considered FTR. A stepwise logistic regression model was created to identify FTR predictors. Independent variables included in the multivariate analysis were age, body mass index, cardiac, renal, and cerebrovascular comorbidity, ppoFEV1%, VATS approach, extended resection, pneumonectomy, and reintervention. A non-parametric ROC curve was constructed to estimate the predictive capacity of the model. RESULTS A total of 2,569 patients were included, of which 223 (8.9%) had major complications and 49 (22%) could not be rescued. Variables associated with FTR were: age (OR: 1.07), history of cerebrovascular accident (OR: 3.53), pneumonectomy (OR: 6.67), and reintervention (OR: 12.26). The area under the ROC curve was 0.82 (95% CI: 0.77-0.88). CONCLUSIONS Overall, 22% of patients with major complications following anatomical lung resection in this series did not survive until discharge. Pneumonectomy and reintervention are the most significant risk factors for FTR.

Abstract
AbstractOBJECTIVESThe objective of this retrospective multi-institutional study was to evaluate the postoperative outcomes of video-assisted thoracoscopic surgery (VATS)-lobectomy (VATS-L) for non-small-cell lung cancer (NSCLC) in patients with impaired lung function. The second end point was to illustrate the effective role of forced expiratory volume in 1 s (FEV1%) and the diffusing capacity of the lung for carbon monoxide (DLCO%) in predicting complications in this population.METHODSData from patients who underwent VATS-L at participating centres were analysed and divided into 2 groups: group A comprised patients with FEV1% and/or DLCO% >60% and group B included patients with impaired lung function defined as FEV1% and/or DLCO% ≤60%. To define clinical predictors of death and complications, we performed univariate and multivariable regression analyses.RESULTSA total of 5562 patients underwent VATS-L, 809 (14.5%) of whom had impaired lung function. The postoperative mortality rate did not differ between the 2 groups (2.3% vs 3.2%; P = 0.77). The percentage of patients who had any complication (21.4% vs 34.2%; P ≤ 0.001), the complication rate (28% vs 49.8%; P ≤ 0.001) and the length of hospital stay (P ≤ 0.001) were higher for patients with limited pulmonary function. Impaired lung function was a strong predictor of overall and pulmonary complications at multivariable analysis.CONCLUSIONSVATS-L for NSCLC can be performed in patients with impaired lung function without increased risk of postoperative death and with an acceptable incidence of overall and respiratory complications. Our analysis suggested that FEV1% and DLCO% play a substantial role in estimating the risk of complications after VATS-L, but their role was less reliable for estimating the mortality.

Abstract
Lung diffusing capacity for carbon monoxide (Dlco) remains the only noninvasive pulmonary function test to provide an integrated picture of gas exchange efficiency in human lungs. Due to its critical dependence on the accessible "alveolar" volume (Va), there remains substantial misunderstanding on the interpretation of Dlco and the diffusion coefficient (Dlco/Va ratio, Kco). This article presents the physiologic and methodologic foundations of Dlco measurement. A clinically friendly approach for Dlco interpretation that takes those caveats into consideration is outlined. The clinical scenarios in which Dlco can effectively assist the chest physician are discussed and illustrative clinical cases are presented.

Abstract
OBJECTIVE Idiopathic interstitial pneumonias (IIPs) are predominantly encountered in the lower lobe, and frequently with concomitant emphysema that is predominantly in the upper lobe. However, the impact of the resection site on surgical outcomes of lung cancer with IIPs remains unclear. This study was conducted to evaluate the surgical outcome between patients undergoing upper or lower lobe resection. METHODS This retrospective study was performed on 1972 patients who underwent surgical resection for lung cancer at our institute between 2009 and 2018. Review of CT findings revealed that 337 (14.1%) patients had IIPs. Morbidity, mortality, and postoperative pulmonary function test (PFT) were compared between patients who underwent upper or lower lobectomy and stratified by presence or absence of emphysema (CPFE and non-CPFE). RESULTS Surgical mortality and morbidity were not statistically different between the two groups regardless of CPFE. The difference between actual and predicted postoperative PFTs was statistically larger in the upper lobectomy compared to the lower lobectomy among the non-CPFE patients. (FVC: p = 0.019, FEV1.0: p = 0.001, %DLCO: p = 0.090) CONCLUSIONS: Site of the resected lobe in lung cancer is not a prognostic factor of surgical mortality and morbidity in patients with IIPs. However, the impact of upper lobectomy on postoperative respiratory function reduction is larger than lower lobectomy in non-CPFE patients.

Abstract
BACKGROUND Postoperative diaphragmatic dysfunction after thoracic surgery is underestimated due to the lack of reproducible bedside diagnostic methods. We used point of care ultrasound to assess diaphragmatic function bedside in patients undergoing video-assisted thoracoscopic or thoracotomic lung resection. Our main hypothesis was that the thoracoscopic approach may be associated with lower incidence of postoperative diaphragm dysfunction as compared to thoracotomy. Furthermore, we assessed the association between postoperative diaphragmatic dysfunction and postoperative pulmonary complications. METHODS This was a prospective observational cohort study. Two cohorts of patients were evaluated: those undergoing video-assisted thoracoscopic surgery versus those undergoing thoracotomy. Diaphragmatic dysfunction was defined as a diaphragmatic excursion less than 10 mm. The ultrasound evaluations were carried out before (preoperative) and after (i.e., 2 h and 24 h postoperatively) surgery. The occurrence of postoperative pulmonary complications was assessed up to 7 days after surgery. RESULTS Among the 75 patients enrolled, the incidence of postoperative diaphragmatic dysfunction at 24 h was higher in the thoracotomy group as compared to video-assisted thoracoscopic surgery group (29 of 35, 83% vs. 22 of 40, 55%, respectively; odds ratio = 3.95 [95% CI, 1.5 to 10.3]; P = 0.005). Patients with diaphragmatic dysfunction on the first day after surgery had higher percentage of postoperative pulmonary complications (odds ratio = 5.5 [95% CI, 1.9 to 16.3]; P = 0.001). Radiologically assessed atelectasis was 46% (16 of 35) in the thoracotomy group versus 13% (5 of 40) in the video-assisted thoracoscopic surgery group (P = 0.040). Univariate logistic regression analysis indicated postoperative diaphragmatic dysfunction as a risk factor for postoperative pulmonary complications (odds ratio = 5.5 [95% CI, 1.9 to 16.3]; P = 0.002). CONCLUSIONS Point of care ultrasound can be used to evaluate postoperative diaphragmatic function. On the first postoperative day, diaphragmatic dysfunction was less common after video-assisted than after the thoracotomic surgery and is associated with postoperative pulmonary complications.

Abstract
Purpose This study aimed to compare lung perfusion scan with single photon emission computed tomography/computed tomography (SPECT/CT) for the evaluation of lung function and to elucidate the most appropriate modality for the prediction of postoperative lung function in patients with lung cancer. Methods A total of 181 patients underwent Tc-99m macroaggregated albumin lung perfusion scan and SPECT/CT to examine the ratio of diseased lung and diseased lobe. Forty-one patients with lung cancer underwent both preoperative and postoperative pulmonary function tests within 1 month to predict postoperative pulmonary function. Predicted postoperative forced expiratory volume in 1 s (ppoFEV1) was calculated by the % radioactivity of lung perfusion scan and SPECT, and the % volume of the residual lung, assessed on CT. Results The ratios of diseased lung as seen on lung perfusion scan and SPECT showed significant correlation, but neither modality correlated with CT. The ratios of the diseased lung and diseased lobe based on CT were higher than the ratios based on either perfusion scan or SPECT, because CT overestimated the function of the diseased area. The lobar ratio of both upper lobes was lower based on the perfusion scan than on SPECT but was higher for both lower lobes. Actual postoperative FEV1 showed significant correlation with ppoFEV1 based on lung perfusion SPECT and perfusion scan. Conclusions We suggest SPECT/CT as the primary modality of choice for the assessment of the ratio of diseased lung area. Both perfusion scan and SPECT/CT can be used for the prediction of postoperative lung function.

Abstract
INTRODUCTION The most suitable treatment in most early-stage lung cancer patients is surgical resection. Despite previously assessing each patient's status being relevant to detect possible complications inherent to surgery, no consensus has been reached on which factors are "high risk" in such patients. Our study aimed to analyse the morbidity and the mortality incidence associated with this surgery in our setting with a multicentre study and to detect risk parameters. METHODS A prospective analysis study with 3,307 patients operated for bronchopulmonary carcinoma in 24 hospitals. Study variables were age, TNM, gender, stage, smoking habit, surgery approach, surgical resection, ECOG, neoadjuvant therapy, comorbidity, spirometric values, and intraoperative and postoperative morbidity and mortality. A multivariate logistic regression analysis of the morbidity and mortality predictor factors was done. RESULTS We recorded 34.2% postoperative morbidity and 2.1% postoperative mortality. Gender, myocardial infarction, angina, ECOG ≥1, COPD, DLCO <60%, clinical pathological status, surgical resection and surgery approach were shown as morbidity and mortality predictor factors in lung cancer surgery in our series. CONCLUSIONS The main variables to consider when assessing the lung cancer patients to undergo surgery are gender, myocardial infarction, angina, ECOG, COPD, DLCO, clinical pathological status, surgical resection and surgery approach.

Abstract
Background Pulmonary function following lung wedge resection is not fully understood. This study aimed to assess the influence of wedge resection upon postoperative pulmonary function. Methods We retrospectively evaluated pulmonary function at 3, 6, and 12 months postoperatively in 29 patients who underwent lung wedge resection. The values of the pulmonary function tests (PFTs) were compared among the time points using a paired t-test. Results The vital capacity (VC) values before surgery and at 3, 6 and 12 months postoperatively were 2,994±793, 2,845±799, 2,941±801, and 2,964±839 mL, respectively. The VC decreased at 3 months postoperatively (P=0.002) and recovered by 6 and 12 months postoperatively (P=0.003 and 0.003, respectively). The VC values at 6 and 12 months postoperatively did not significantly differ from that before surgery (P=0.152 and 0.361, respectively). The forced expiratory volume in one second (FEV1) values before surgery and at 3, 6, and 12 months postoperatively were 2,156±661, 2,034±660, 2,091±672 and 2,100±666 mL, respectively. The values decreased at 3 months postoperatively (P<0.001) and recovered; however, they remained lower than the preoperative value (P=0.036). Conclusions The postoperative VC decreased temporarily but recovered to near the preoperative level after 12 months. We concluded that the loss of VC following lung wedge resection is minimal. These findings are beneficial for planning surgery and explaining the procedure to patients who are undergoing lung wedge resection.

Abstract
BACKGROUND The purpose of this study was to analyze cardiopulmonary fitness in Phase I cardiac rehabilitation on the prognosis of patients with ST-Elevation Myocardial Infarction (STEMI) after percutaneous coronary intervention (PCI). METHODS The study enrolled a total of 499 STEMI patients treated with PCI between January 2015 and December 2015. Patients were assigned to individualized exercise prescriptions (IEP) group and non-individualized exercise prescriptions (NIEP) group according to whether they accept or refuse individualized exercise prescriptions. We compared the incidence of major cardiovascular events between the two groups. IEP group were further divided into two subgroups based on prognosis status, namely good prognosis (GP) group and poor prognosis (PP) group. Key cardio-pulmonary exercise testing (CPX) variables that may affect the prognosis of patients were identified through comparison of the cardio-respiratory fitness (CRF). RESULTS There is no significant difference in the incidence of cardio-genetic death, re-hospitalization, heart failure, stroke, or atrial fibrillation between the IEP and the NIEP group. But the incidence of total major adverse cardiac events (MACE) was significantly lower in the IEP group than in the NIEP group (P = 0.039). The oxygen consumption (VO2) at ventilation threshold (VT), minute CO2 ventilation (E-VCO2), margin of minute ventilation carbon dioxide production (△CO2), rest partial pressure of end-tidal carbon dioxide(R-PETCO2), exercise partial pressure of end-tidal carbon dioxide(E-PETCO2) and margin of partial pressure of end-tidal carbon dioxide(△PETCO2) were significantly higher in the GP subgroup than in the PP subgroup; and the slope for minute ventilation/carbon dioxide production (VE/VCO2) was significantly lower in GP subgroup than in PP subgroup (P = 0.010). The VO2 at VT, VE/VCO2 slope, E-VCO2, △CO2, R-PETCO2, E-PETCO2 and margin of partial pressure of end-tidal carbon dioxide CO2 (△PETCO2) were predictive of adverse events. The VO2 at VT was an independent risk factor for cardiovascular disease prognosis. CONCLUSIONS Individualized exercise prescription of Phase I cardiac rehabilitation reduced the incidence of cardiovascular events in patients with STEMI after PCI. VO2 at VT is an independent risk factor for cardiovascular disease prognosis, and could be used as an important evaluating indicator for Phase I cardiac rehabilitation.

Abstract
BACKGROUND Estimation of the perioperative risk plays a decisive role in the surgical indications, particularly in view of the demographic change. For this reason, prehabilitation concepts for reducing perioperative risk nowadays play an increasingly important role. OBJECTIVE Presentation of the current recommendations for preoperative diagnostics in thoracic surgical interventions as well as existing prehabilitation concepts and their practical applicability. MATERIAL AND METHODS A selective review of the literature was carried out by searching the electronic databases PubMed, Cochrane Library and ISRCTN, including the guidelines of the American College of Chest Physicians (ACCP) and the European Society of Thoracic Surgery (ESTS). RESULTS Preconditioning includes the conservative treatment of underlying diseases, smoking cessation and prehabilitation. Prehabilitation is an increasingly pressing concept in routine clinical practice, even though the evidence is limited due to the very heterogeneous study situation. Overall, however, there is a tendency for positive effects on the quality of life and postoperative complications as well as convalescence. CONCLUSION In addition to preoperative diagnostics to assess the perioperative risk, effective preconditioning of patients is also necessary. For this an interdisciplinary approach including anesthesia, pneumology, psychotherapy and physiotherapy is necessary. In addition to the conservative medicinal optimization, prehabilitation concepts are gaining in importance and will certainly become established in routine clinical practice. From the surgical perspective, minimally invasive approaches and parenchyma-sparing resections also serve to reduce risks.

Abstract
Extremely severe scoliosis patients, especially main thoracic Cobb' s angle >150°, often have severe thoracic deformity and pulmonary dysfunction, even the scoliosis is reduced by halo-pelvic traction, the improvement of pulmonary function is not satisfactory, the risk of spinal osteotomy in the next stage is still very high and left with obvious thoracic deformity. How to further improve the pulmonary function and appearance of these patients is a difficult problem to be solved.Twenty extremely severe scoliosis patients with severe pulmonary dysfunction who underwent concave-side thoracoplasty in our hospital from September 2014 to September 2017 were included, data of thoracic volume and pulmonary function were collected before and after operation. The pulmonary function value reported was predicted forced vital capacity (FVC%), T-test was used to analyze the changes of the data by the statistical software SPSS21.0.The 20 patient's averaged Cobb's angle of main thoracic was 163° ± 8° at admission and all of them with severe pulmonary dysfunction before concave-side thracoplasty. After operation, the thoracic volume of patients increased by 500.9 ± 222.9 mL, FVC% increased by 8.9% ± 7.5%. Both the difference has statistical significance (P < .01).Concave-side thoracoplasty based on the halo-pelvic traction cannot only enlarge the volume of the concave thoracic cavity, lighten the compression of lung and further improve the pulmonary function of extremely severe scoliosis, but also can strengthen the correction of scoliosis and spinal rotation. Therefore, it is a safe and effective surgical approach.

Abstract
OBJECTIVE It is widely accepted that exercise tolerance tests are applicable in perioperative risk assessment for patients who undergo pulmonary resection; however, the relevance of desaturation during the test is unclear. The purpose of this study was to investigate whether the occurrence of desaturation during a stair-climbing test can be a predictor of postoperative complications among patients who will undergo pulmonary resection and are considered "normal risk" according to published guidelines. METHODS Desaturation was defined as a depression of more than 4% points on a pulse oximeter during stair climbing. Among 186 consecutive patients who underwent pulmonary resection, 162 patients who could climb to the 6th floor were selected for the study (excluding 21 patients who could not stair-climb and 3 patients who could not climb from the first floor to the sixth floor). The relationship of desaturation with postoperative complication was investigated using parameters of cardio-pulmonary status associated with additional foci of oxygen supply duration, intensive care unit stay duration, and hospital stay duration. RESULTS The occurrence ratio of postoperative complications > grade 3 (Clavien-Dindo classification) was 0.75% (1/133) among patients without desaturation and 17.2% (5/29) in patients with desaturation (difference: p = 0.0002). In addition, DS was an indicator of prolonged oxygen supply duration, intensive care unit stay duration, and hospital stay duration. CONCLUSION The occurrence of desaturation during a stair-climbing test for patients who will undergo pulmonary resection can be a predictor of postoperative complications among patients who are classified as having normal risk.

Abstract
Background This study aims to investigate the effects of shortterm intense pulmonary rehabilitation on respiratory function in patients with lung cancer who were defined as inoperable due to insufficient pulmonary reserve. Methods A total of 25 patients (24 males, 1 female; mean age 62 years; range, 50 to 72 years) who were histologically diagnosed as non-small cell lung carcinoma, considered functionally inoperable due to high risk of an estimated postoperative complication, and suitable for surgical resection according to tumor stage were included in the study. Patients received chest physiotherapy, self-walking and inspiratory muscle training for two weeks. The forced expiratory volume in one second, forced vital capacity, modified Medical Research Council dyspnea scale, six-minute walking distance, maximal inspiratory and expiratory pressures for respiratory muscle strength measurements, and predicted peak maximal oxygen consumption were examined. Results After pulmonary rehabilitation, there was statistically significant improvement in the six-minute walking distance (53 m, p<0.001), dyspnea perception (p<0.001), maximal inspiratory pressure (12 cm H2O, p<0.001), forced vital capacity (p<0.001), predicted forced expiratory volume in one second (%) (p=0.001), forced expiratory volume in one second (Δ forced expiratory volume in one second= 150 mL, p=0.001; Δ maximum value of forced expiratory volume in one second: 650 mL), and predicted maximal oxygen consumption (p<0.001). At the end of the rehabilitation, 60% of the patients (n=15) reevaluated by the surgeons could be operated. Conclusion Short-term intensive pulmonary rehabilitation improves lung functions and exercise capacity while decreasing dyspnea perception. In our study, thanks to the gains derived from the exercise, approximately more than half of the patients could be operated. Therefore, it may be useful to refer patients to rehabilitation before establishing a decision of inoperability.
