Background This study aimed to characterize the demographics, microbiology, management and treatment outcomes of mediastinitis according to the origin of the infection. Methods This retrospective observational study enrolled patients who had mediastinitis diagnosed according to the criteria defined by the Centers for Disease Control and Prevention and were treated in Strasbourg University Hospital, France, between 1 January 2010 and 31 December 2020. Results We investigated 151 cases, including 63 cases of poststernotomy mediastinitis (PSM), 60 cases of mediastinitis due to esophageal perforation (MEP) and 17 cases of descending necrotizing mediastinitis (DNM). The mean patient age (standard deviation) was 63 (14.5) years, and 109 of 151 patients were male. Microbiological documentation varied according to the origin of the infection. When documented, PSM cases were mostly monomicrobial (36 of 53 cases [67.9%]) and involved staphylococci (36 of 53 [67.9%]), whereas MEP and DNM cases were mostly plurimicrobial (38 of 48 [79.2%] and 8 of 12 [66.7%], respectively) and involved digestive or oral flora microorganisms, respectively. The median duration of anti-infective treatment was 41 days (interquartile range, 21–56 days), and 122 of 151 patients (80.8%) benefited from early surgical management. The overall 1-year survival rate was estimated to be 64.8% (95% confidence interval, 56.6%–74.3%), but varied from 80.1% for DNM to 61.5% for MEP. Conclusions Mediastinitis represents a rare yet deadly infection. The present cohort study exhibited the different patterns observed according to the origin of the infection. Greater insight and knowledge on these differences may help guide the management of these complex infections, especially with respect to empirical anti-infective treatments. [ABSTRACT FROM AUTHOR]

Background: The national Epithor database was initiated in 2003 in France. Fifteen years on, a quality assessment of the recorded data seemed necessary. This study examines the completeness of the data recorded in Epithor through a comparison with the French PMSI database, which is the national medico-administrative reference database. The aim of this study was to demonstrate the influence of data quality with respect to identifying 30-day mortality hospital outliers. Methods: We used each hospital’s individual FINESS code to compare the number of pulmonary resections and deaths recorded in Epithor to the figures found in the PMSI. Centers were classified into either the good-quality data (GQD) group or the low-quality data (LQD) group. To demonstrate the influence of case-mix quality on the ranking of centers with low-quality data, we used 2 methods to estimate the standardized mortality rate (SMR). For the first (SMR1), the expected number of deaths per hospital was estimated with risk-adjustment models fitted with low-quality data. For the second (SMR2), the expected number of deaths per hospital was estimated with a linear predictor for the LQD group using the coefficients of a logistic regression model developed from the GQD group. Results: Of the hospitals that use Epithor, 25 were classified in the GQD group and 75 in the LQD group. The 30-day mortality rate was 2.8% (n = 300) in the GQD group vs. 1.9% (n = 181) in the LQD group (P <0.0001). The between-hospital differences in SMR1 appeared substantial (interquartile range (IQR) 0–1.036), and they were even higher in SMR2 (IQR 0–1.19). SMR1 identified 7 hospitals as high-mortality outliers. SMR2 identified 4 hospitals as high-mortality outliers. Some hospitals went from non-outlier to high mortality and vice-versa. Kappa values were roughly 0.46 and indicated moderate agreement. Conclusion: We found that most hospitals provided Epithor with high-quality data, but other hospitals needed to improve the quality of the information provided. Quality control is essential for this type of database and necessary for the unbiased adjustment of regression models. [ABSTRACT FROM AUTHOR]

• Management of non-bulky/non-infiltrative N2 disease is controversial. • With increasing N2 disease extent, there is a trend towards chemoradiotherapy followed by consolidation immunotherapy as first-line therapy. • Multidisciplinary decision-making is important in this challenging patient population. The optimal management of patients with non-bulky/non-infiltrative stage IIIA N2 non-small cell lung cancer (NSCLC) remains controversial. In this modified Delphi study from France, we aimed to generate agreement through multidisciplinary decision-making on the clinical management of patients with non-bulky/non-infiltrative N2 NSCLC. An expert panel of 30 physicians from different specialities completed two Delphi rounds of a 76-item questionnaire, pertaining to: pathological confirmation of N2 disease; initial treatment approach; treatment approach in case of disease progression/stability following neoadjuvant chemotherapy; treatment approach taking into account various patient and tumour characteristics. Each questionnaire item was scored using a 9-point Likert scale. Consensus in agreement was achieved if ≥ 80 % of responses to a questionnaire item were scored between 7 and 9 and if the median value of the score to the item was ≥ 7. Regarding the pathologic confirmation of N2 disease, agreement (up to 100 %) was reached on endobronchial ultrasound/endoscopic ultrasound as the preferred method of initial mediastinal staging for paratracheal lymph nodes. There was also panellist agreement (up to 93 %) on the adoption as first-line treatment of surgery and (neo)adjuvant chemotherapy in patients with single-station disease, and of concurrent chemoradiotherapy followed by adjuvant immunotherapy in those with multi-station N2 disease. Panellists further agreed on the use of a non-surgical strategy, i.e., concurrent chemoradiotherapy with adjuvant immunotherapy, in patients with single-station N2 disease in case of: involvement of ≥ 2 mediastinal lymph nodes; disease progression following neoadjuvant chemotherapy; compromised cardiopulmonary function if compatible with radiotherapy; anticipated right pneumonectomy. This Delphi study reinforces the importance of multidisciplinary discussions leading to the best individual approach to the clinical management of patients with non-bulky/non-infiltrative N2 NSCLC, a challenging heterogeneous population.

To study patient survival and glycemic control before and after lung transplantation (LTx) according to the diabetes status in patients submitted to an organized management of diabetes mellitus (DM) at the Strasbourg University Hospital, France. Two hundred and sixty-seven LTx recipients were included retrospectively and analyzed according to diabetes status: pretransplant diabetes, new-onset diabetes mellitus after transplant (NODAT) or no diabetes. Organized DM management was coordinated by a diabetologist trained in DM management before and after transplantation and included pretransplant screening, a close monitoring of glycemia after transplant and optimized treatment before and after LTx. DM was well-controlled after transplantation: mean glycosylated hemoglobin and fasting blood glucose levels after LTx were 5.8 ± 0.2% and 5.4 ± 0.1 mmol/L respectively, in pretransplant DM patients and 5.7 ± 0.1% and 5.6 ± 0.2 mmol/L respectively, in NODAT patients. The overall median survival time was 8.3 ± 1.9 years. Pretransplant DM increased the risk of mortality (1.82-fold increase; 95% confidence interval, 1.08-3.06; P =.02) in LTx recipients. Organized management of diabetes achieved very satisfactory glycemic control in both pretransplant DM and NODAT patients. However, no specific protocols have been created for managing DM following LTx. As DM continues to become an increasing comorbidity in LTx, there exist a significant need of studies in this area. • This study is the first to describe diabetes management in lung transplant recipients before and after transplantation. There is a very rigorous DM management in Strasbourg lung transplant program with a diabetologist trained in DM management before and after lung transplantation, who was integrated in the transplant team. • In our study, well-controlled pre- and post-transplant diabetic patients were given lower glycosylated hemoglobin and fasting blood glucose levels than the diabetic population. • Our data showed that pre-transplant diabetes was an independent predictor of mortality, whereas new-onset diabetes after transplantation was not.

Background: Extracorporeal membrane oxygenation (ECMO) is increasingly used as a bridge to lung transplantation (LTx). However, data concerning this approach remain limited. Methods: We retrospectively reviewed the medical records of all patients in France who received ECMO as a bridge to LTx from 2007 to 2011. Post-transplant survival and associated factors were assessed by the Kaplan-Meier method and the Cox model. Results: Included were 36 patients from 11 centers. Indications for LTx were cystic fibrosis (CF) in 20 (56%), pulmonary fibrosis (PF) in 11 (30%), and other diagnoses in 5 (14%). ECMO was venovenous for 27 patients (75%) and venoarterial for 9 (25%). Mean follow-up was 17 months. Bridging to LTx was achieved in 30 patients (83%); however, only 27 patients (75%) survived the LTx procedure, and 20 (56%) were discharged from hospital. From ECMO initiation, 2-year survival rates were 50.4% overall, 71.0% for CF patients, 27.3% for PF patients, and 20.0% for other patients (p < 0.001). From LTx, 2-year survival rates were 60.5% overall, 71.0% for CF patients, 42.9% for PF patients, and 33.0% for other patients (p = 0.04). Conclusions: Our study confirms that the use of ECMO as a bridge to LTx in France could provide a medium-term survival benefit for LTx recipients with critical conditions. Survival differed by underlying respiratory disease. Larger studies are needed to further define the optimal use of ECMO. [Copyright &y& Elsevier]

BACKGROUND Lung transplantation (LTx) is a life-extending therapy for specific patients with terminal lung diseases. This study aimed to evaluate the associations and causes of 1-year mortality after lung transplantation at Strasbourg University Hospital, France, between 2012 and 2021. MATERIAL AND METHODS We carried out a retrospective analysis on 425 patients who underwent LTx at Strasbourg University Hospital between January 1, 2012, and December 31, 2021. Pre-transplant, perioperative, and postoperative data were collected from the electronic medical records. RESULTS Among all patients, 94.6% had a LTx, 4.0% a heart-lung transplantation, and 1.4% underwent pancreatic islet-lung transplantation. The median age at transplantation was 57 years, with 55.3% male patients. The main native lung disease leading to LTx was chronic obstructive pulmonary disease in 51.1% of patients; 16.2% needed super-urgent LTx. The 1-year mortality rate was 11.5%. Most deaths were either caused by multi-organ failure or septic shock. In our multivariate analysis, we identified 3 risk factors significantly related to 1-year mortality after LTx: body mass index (BMI) between 25 and 30 kg/m² vs BMI between 18.5 and 25 kg/m² (P=0.032), postoperative extracorporeal membrane oxygenation support (P=0.034), and intensive care unit length of stay after transplantation (P<0.001). Two other factors were associated with a significantly lower 1-year mortality risk: longer hospital stay after LTx (P=0.024) and tacrolimus prescription (P=0.004). CONCLUSIONS Our study reported a 1-year mortality rate of 11.5% after LTx. Although LTx candidates are carefully selected, additional data are required to improve understanding of the risk factors for post-LTx mortality.

Introduction: Lung graft allocation can be based on a score (Lung Allocation Score) as in the USA or sequential proposals combined with a discrete priority model as in France. We aimed to analyse the impact of allocation policy on the outcome of urgent lung transplantation (LT)., Methods: US United Network for Organ Sharing (UNOS) and French Cristal databases were retrospectively reviewed to analyse LT performed between 2007 and 2017. We analysed the mortality risk of urgent LT by fitting Cox models and adjusted Restricted Mean Survival Time. We then compared the outcome after urgent LT in the UNOS and Cristal groups using a propensity score matching., Results: After exclusion of patients with chronic obstructive pulmonary disease/emphysema and redo LT, 3775 and 12 561 patients underwent urgent LT and non-urgent LT in the USA while 600 and 2071 patients underwent urgent LT and non-urgent LT in France. In univariate analysis, urgent LT was associated with an HR for death of 1.24 (95% CI 1.05 to 1.48) in the Cristal group and 1.12 (95% CI 1.05 to 1.19) in the UNOS group. In multivariate analysis, the effect of urgent LT was attenuated and no longer statistically significant in the Cristal database (HR 1.1 (95% CI 0.91 to 1.33)) while it remained constant and statistically significant in the UNOS database (HR 1.12 (95% CI 1.05 to 1.2)). Survival comparison of urgent LT patients between the two countries was significantly different in favour of the UNOS group (1-year survival rates 84.1% (80.9%-87.3%) vs 75.4% (71.8%-79.1%) and 3-year survival rates 66.3% (61.9%-71.1%) vs 62.7% (58.5%-67.1%), respectively)., Conclusion: Urgent LT is associated with adverse outcome in the USA and in France with a better prognosis in the US score-based system taking post-transplant survival into account. This difference between two healthcare systems is multifactorial., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024. No commercial re-use.

Background: The management of stage III non-small-cell lung cancer (NSCLC) remains heterogeneous and complex, even after the approval of immune checkpoint inhibitors post-chemoradiotherapy (CRT). This observational study from France evaluated real-world practices in managing stage III NSCLC., Methods: Between 2020 and 2022, we conducted a physician practice survey in 41 medical centers across France, and retrospectively analyzed aggregated information from 417 consecutive charts of patients with stage III NSCLC. We collected information on diagnostic and staging procedures, biomarker testing, surgical and non-surgical treatments, and follow-up., Results: According to the physician survey, diagnostic workup of stage III NSCLC primarily relied on positron emission tomography/computed tomography and brain magnetic resonance imaging, performed for the majority of patients in 100 % and 78 % of centers, respectively. Of 417 patient charts, 414 were evaluable with 53 % of patients having stage IIIA disease, 37 % IIIB, and 10 % IIIC. The most common node involvement was N2 (59 %). Programmed death-ligand 1 testing was conducted for 98 % of patients. Invasive staging (mediastinoscopy or endobronchial ultrasound) was performed in 41 % of patients, of whom 83 % had N2 or N3 nodal involvement. Surgical resection was offered to 120 patients (29 %), with 85 % achieving R0 resection. In 292 charts of patients with unresectable stage III NSCLC, 190 patients (65 %) were offered CRT followed by consolidation immunotherapy. Within these patients, concurrent CRT was more frequently employed (52 %) than sequential CRT (13 %)., Conclusions: Diagnostic procedures and treatment modalities in French medical centers generally align with clinical guidelines for stage III NSCLC, except for invasive staging that was less commonly performed than expected., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Jean-Bernard Auliac reports financial support was provided by AstraZeneca.

Introduction: Due to the COVID-19 pandemic, France underwent several lockdown periods during 2020. Our aim was to evaluate its clinical and social impact on lung transplant (LT) patients treated at Strasbourg University Hospital, by comparing three periods: first lockdown (T1: March-May 2020), end of the first lockdown (T2: May-October 2020), and second lockdown (T3: November-December 2020) and the incidence of COVID-19 infections. A cohort of patients with rare lung disease (RLD) was also studied during T2., Methods: We used clinical and paraclinical data collected during routine follow-up. A questionnaire was submitted to each patient at each period to assess their lifestyle, adherence to protective measures against COVID-19, contacts with their family and friends, and contagion risk. The incidence of new COVID-19 cases was also assessed., Results: Overall, 283 LT and 57 RLD patients were included. We observed only eight COVID-19 cases over the three periods (n = 4 during T1, n = 0 during T2, and n = 4 during T3) in LT patients, with 37.5 % of patients hospitalized, no ICU transfers, and 100 % favorable outcomes. No case of COVID-19 was diagnosed in the RLD cohort. When comparing the three periods in the LT group, fewer patients limited their out-of-home activities during T2 (p < 0.0001). The frequency of these activities increased after the first lockdown, for the purchase of basic necessities (p < 0.0001), and professional activity continued (p = 0.008). We observed a significant increase in unscheduled medical consultations and in the prescription of anti-infective treatments during the end of the lockdown (p = 0.0002 and p = 0.005, respectively). Adherence to lockdown and to protective measures was high in both groups of patients., Conclusion: COVID-19 incidence remained low in both groups and there were significant lifestyle evolutions in LT patients and in those with RLD between first and second lockdown., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Objectives: Several studies have reported that patients operated on for non-small cell lung cancer (NSCLC) are at high risk of second primary lung cancer (SPLC). However, widely varying estimates of this risk have been reported, with very few studies taking into account that these patients are at particularly high competing risk of death, due to recurrence of the initial disease and to comorbidities. Risk factor evaluation over time has significant repercussions on the post-surgery surveillance strategy offered for NSCLC. This study primarily sought to measure the risk of SPLC in a long-term follow-up series, using statistical methods considering competing risks of death., Materials and Methods: The cumulative SPLC risk was estimated using the cumulative incidence of patients with completely resected Stage I-III NSCLC diagnosed between 2002 and 2015 based on the Doubs and Belfort cancer registry (France). A proportional sub-distribution hazard model ( sd RH) was used to investigate factors associated with SPLC risk in the presence of competing risks., Results: Among the 522 patients, adenocarcinoma and Stage I or II disease accounted for 52.3% and 75.7% of patients, respectively. Overall, 84 patients developed SPLC (16.1%). The cumulative risk of SPLC was 20.2% at 10 years post-surgery (95% confidence interval [CI]: 15.3-23.2), and 25.2% (CI: 19.4-31.3) at 14 years post-surgery. On multivariate analysis, the SPLC risk was significantly higher in patients with postoperative thoracic radiotherapy ( sd RH 2.79; 95% CI: 1.41-5.52; p = 0.003)., Conclusion: This study using appropriate statistical methods to consider competing risks showed that after complete NSCLC resection, the cumulative incidence function of SPLC was high, with patients receiving postoperative thoracic radiotherapy at higher risk. These data support the need for life-long follow-up of patients who undergo NSCLC surgery, with the objective of screening for SPLC., (Copyright © 2019 Elsevier B.V. All rights reserved.)

The anti-tumour and anti-metastatic properties of heparins have not been tested in patients with early stage cancer. Whether adjuvant low molecular weight heparin (LMWH) tinzaparin impacts the survival of patients with resected non-small cell lung cancer (NSCLC) was investigated.Patients with completely resected stage I, II or IIIA NSCLC were randomly allocated to receive subcutaneous tinzaparin 100 IU·kg -1 once a day for 12 weeks or no treatment in addition to standard of care. The trial was open-label with blinded central adjudication of study outcomes. The primary outcome was overall survival.In 549 patients randomised to tinzaparin (n=269) or control (n=280), mean±sd age was 61.6±8.9 years, 190 (34.6%) patients had stage II-III disease, and 220 (40.1%) patients received adjuvant chemotherapy. Median follow-up was 5.7 years. There was no significant difference in overall survival between groups (hazard ratio (HR) 1.24, 95% CI 0.92-1.68; p=0.17). There was no difference in the cumulative incidence of recurrence between groups (subdistribution HR 0.94, 95% CI 0.68-1.30; p=0.70).Adjuvant tinzaparin had no detectable impact on overall and recurrence-free survival of patients with completely resected stage I-IIIA NSCLC. These results do not support further clinical evaluation of LMWHs as anti-tumour agents., Competing Interests: Conflict of interest: G. Meyer reports grants and non-financial support from Leo Pharma, outside the submitted work.

Background: Bronchopleural fistula (BPF) remains a rare but fatal complication of thoracic surgery. The aim of this study was to develop and validate a predictive model of BPF after pulmonary resection and to identify patients at high risk for BPF., Methods: From January 2005 to December 2012, 34,000 patients underwent major pulmonary resection (lobectomy, bilobectomy, or pneumonectomy) and were entered into the French National database Epithor. The primary outcome was the occurrence of postoperative BPF at 30 days. The logistic regression model was built using a backward stepwise variable selection., Results: Bronchopleural fistula occurred in 318 patients (0.94%); its prevalence was 0.5% for lobectomy (n = 139), 2.2% for bilobectomy (n = 39), and 3% for pneumonectomy (n = 140). The mortality rate was 25.9% for lobectomy (n = 36), 16.7% for bilobectomy (n = 6), and 20% for pneumonectomy (n = 28). In the final model, nine variables were selected: sex, body mass index, dyspnea score, number of comorbidities per patient, bilobectomy, pneumonectomy, emergency surgery, sleeve resection, and the side of the resection. In the development data set, the C-index was 0.8 (95% confidence interval: 0.78 to 0.82). This model was well calibrated because the Hosmer-Lemeshow test was not significant (χ(2) = 10.5, p = 0.23). We then calculated the logistic regression coefficient to build the predictive score for BPF., Conclusions: This strong model could be easily used by surgeons to identify patient at high risk for BPF. This score needs to be confirmed prospectively in an independent cohort., (Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.)

The aim of this study was to assess the evolution of survival in patients treated surgically for non-small cell lung cancer (NSCLC) between 2005 and 2012.From January 2005 to December 2012, 34 006 patients underwent pulmonary resection for NSCLC and were included in the French national database Epithor. Patients' characteristics, procedures and survival were analysed. Survival according to the management was evaluated for each 2-year period separately: 2005-2006, 2007-2008, 2009-2010 and 2011-2012.The proportions of early-stage cancers and adenocarcinomas increased significantly over the periods. 3-year overall survival (OS) increased significantly from 80.5% for the first period to 81.4% for the last period. For the periods 2005-2006 and 2007-2008, 3-year OS was lower after segmentectomy than after lobectomy (77 and 73% versus 82 and 83%, respectively). For the periods 2009-2010 and 2011-2012, 3-year OS in the two sub-groups was similar. OS after bi-lobectomy or pneumonectomy was lower than after lobectomy for all periods analysed. Systematic nodal dissection increased OS for all periods. Chemotherapy but not radiotherapy improved OS in the first 12 postoperative months for all periods.Changes in histological type and stage linked to advances in surgical and medical practices since 2005 led to an increase in OS in patients with surgical-stage NSCLC., (Copyright ©ERS 2015.)

Objective: The study objective was to determine contemporary early outcomes associated with pneumonectomy for lung cancer and to identify their predictors using a nationally representative general thoracic surgery database (EPITHOR)., Methods: After discarding inconsistent files, a group of 4498 patients who underwent elective pneumonectomy for primary lung cancer between 2003 and 2013 was selected. Logistic regression analysis was performed on variables for mortality and major adverse events. Then, a propensity score analysis was adjusted for imbalances in baseline characteristics between patients with or without neoadjuvant treatment., Results: Operative mortality was 7.8%. Surgical, cardiovascular, pulmonary, and infectious complications rates were 14.9%, 14.1%, 11.5%, and 2.7%, respectively. None of these complications were predicted by the performance of a neoadjuvant therapy. Operative mortality analysis, adjusted for the propensity scores, identified age greater than 65 years (odds ratio [OR], 2.1; 95% confidence interval [CI], 1.5-2.9; P < .001), underweight body mass index category (OR, 2.2; 95% CI, 1.2-4.0; P = .009), American Society of Anesthesiologists score of 3 or greater (OR, 2.310; 95% CI, 1.615-3.304; P < .001), right laterality of the procedure (OR, 1.8; 95% CI, 1.1-2.4; P = .011), performance of an extended pneumonectomy (OR, 1.5; 95% CI, 1.1-2.1; P = .018), and absence of systematic lymphadenectomy (OR, 2.9; 95% CI, 1.1-7.8; P = .027) as risk predictors. Induction therapy (OR, 0.63; 95% CI, 0.5-0.9; P = .005) and overweight body mass index category (OR, 0.60; 95% CI, 0.4-0.9; P = .033) were protective factors., Conclusions: Several risk factors for major adverse early outcomes after pneumonectomy for cancer were identified. Overweight patients and those who received induction therapy had paradoxically lower adjusted risks of mortality., (Copyright © 2015 The American Association for Thoracic Surgery.

Objective: Our objective was to analyze the time trend variation of 30-day mortality after lung cancer surgery, and to quantify the impact of surgeon and hospital volumes over a 5-year period in France., Methods: We used Epithor, the French national thoracic database and benchmark tool, which catalogues more than 180,000 procedures of 89 private and public hospitals in France. From January 2005 to December 2010, 19,556 patients who underwent major lung resection (lobectomy, bilobectomy, pneumonectomy) were included in our study. Multilevel logistic models were designed to investigate the relationship between 30-day mortality and surgeon (model 1) or hospital (model 2) volumes. The 3 levels considered were the patient, the surgeon, and the hospital., Results: From 2005 to 2007, the 30-day mortality of patients who underwent major lung resection averaged 10%, and then decreased until it reached 3.8% in 2010 (P < .0001). A significant decrease in 30-day mortality was observed over time (P = .0046). During the study period, the mean annual number of procedures per surgeon was 46.1 (standard deviation [SD] = 23.6) and per hospital was 97.9 (SD = 50.8). Model 1 showed that surgeon volume had a significant impact on 30-day mortality (P = .03), whereas model 2 failed to show that hospital volume influenced 30-day mortality (P = .75)., Conclusions: Since 2007, when France's first National Cancer Plan became effective, 30-day mortality of primary lung cancer surgery has decreased and currently measures 3.8%. Low mortality was correlated with higher surgeon volume but was not influenced by hospital volume, which cannot be considered a proxy measure for determining the safety of lung cancer surgery., (Copyright © 2014 The American Association for Thoracic Surgery.

Objectives: Nutritional assessment is not included yet as a major recommendation in lung cancer guidelines. The purpose of this study was thus to assess the influence on surgical outcome of the nutritional status of patients with primary lung cancer undergoing lobectomy., Methods: We queried Epithor, the national clinical database of the French Society of Thoracic and Cardiovascular Surgery, and identified a retrospective cohort of 19 635 patients having undergone lobectomy for a primary lung cancer in the years 2005-11. Their nutritional status was categorized according to the WHO definition: underweight (BMI < 18.5): 857 patients (4.4%), normal (18.5 ≤ BMI < 25): 9391 patients (47.8%), overweight (25 ≤ BMI < 30): 6721 patients (34.2%), obese (BMI ≥ 30): 2666 patients (13.6%). Operative mortality, pulmonary, cardiovascular, infectious and surgical complications rates were collected and analysed for these various BMI groups., Results: In the normal-weight category, operative mortality, pulmonary, surgical, cardiovascular and infectious complications rates were 2.7, 14.6, 13.8, 5.5 and 4.1%, respectively. When compared with that of normal BMI patients, adjusted operative mortality was significantly lower in overweight (2.3%; odd ratio (OR): 0.72 [95% confidence interval (CI): 0.59-0.89]; P = 0.002) and obese patients (1.9%, OR: 0.54 [95% CI: 0.40-0.74]; P < 0.001), and significantly higher in underweight patients (4.1%, OR: 1.89 [95% CI: 1.30-2.75]; P = 0.001). Underweight patients experienced significantly more pulmonary (21.1%; P < 0.001), surgical (23.2%; P < 0.001) and infectious (5.1%; P = 0.05) complications (P < 0.0001). Among surgical complications, prolonged air leaks (17.6%; P < 0.001) and bronchial stump dehiscence (1.5%; P = 0.001) were significantly more frequent in underweight patients than in normal BMI patients. Obesity was not associated with increased incidence of postoperative complications, except for arrhythmia (5.6%; P < 0.05), deep venous thrombosis and pulmonary embolism (1.5%; P = 0.005). Moreover, a statistical protective effect of obesity was observed regarding surgical complications (7.1%; P < 0.001)., Conclusions: Despite having an increased risk of some postoperative cardiovascular complications, obese patients should undergo surgical standard of care therapy for appropriately stage-specific lung cancer. In underweight patients, in addition to preoperative rehabilitation including a nutritional program, attention should be given to aggressive prophylactic respiratory therapy in the perioperative period, and specific intraoperative actions to prevent prolonged air leaks and bronchial stump dehiscence.

Objectives: Lung transplantation is the only life-saving treatment for end-stage respiratory disease. The outcome will depend on the graft quality, surgical conditions and recipient factors. Twinned single-lung transplantation defines as two different recipients treated with lung grafts from the same donor. Recipient-dependent factors of the outcome can be studied more accurately as the graft quality is supposed equal for both recipients., Methods: We reviewed all single-lung transplantations performed in France between 1998 and 2008 in the French registry run by the 'Agence de Biomédecine'. Criteria for donor lung quality and twinned recipient data were recorded in a database. The whole medical history and the transplantation outcome were reviewed for each patient and compared with its twin recipient. We compared twins on the basis of their opposed characteristics and on the basis of the opposed endpoint outcome. Endpoints were primary graft dysfunction (PGD) grade III, and mortality at 1, 3 and 12 months., Results: A total of 387 single-lung transplantations were performed in 10 French centres; 180 were twinned recipients from 90 donors. Statistical analysis revealed a significantly different outcome for PGD only. PGD was significantly higher (P < 0.05) in fibrosis recipients compared with emphysema twins. In 28 pairs (31%), the outcome was discordant for PGD, and fibrosis was significantly more often involved compared with emphysema (P = 0.04). Sixty-two pairs had a similar outcome: two pairs showed PGD in both recipients while 60 pairs were free of PGD., Conclusions: We conclude that recipient's disease is a major determinant of the outcome. Fibrosis is associated with an increased risk for PGD.

Objectives: The purpose of this study was to assess the postoperative morbidity of patients ≥75 years with non-small cell lung cancer (NSCLC) who underwent neoadjuvant chemotherapy, comparing them to younger patients., Methods: We performed a case-control study over a 5-year period using Epithor, the French Society of Thoracic and Cardiovascular Surgery database, including to date more than 160,000 procedures from 103 institutions. We collected prospectively the data concerning 1510 patients with NSCLC who underwent preoperative chemotherapy, from January 2005 to December 2009. In order to compare patients with similar characteristics, we matched the 81 patients ≥75 to 81 controls (<75) for gender, American Society of Anesthesia (ASA) score, Performance Status (PS), Forced Expiratory Volume (FEV1) and histological subtype of the tumor. The patients of the control group were randomized within the 1429 patients <75 included. Lung cancer surgical treatment, post-operative morbidity and mortality rates, and length of stay (LOS) were compared between the two age groups., Results: There was no significant difference in type of resection between the two groups (p=0.07): pneumonectomy 15% (n=12) for patients ≥75 vs 28% (n=23) for younger patients, lobectomy 65% (n=53) vs 54% (n=44), bilobectomy 14% (n=11) vs 6% (n=5) and sub-lobar resection 4% (n=3) for the two groups. There was no significant difference in type of mediastinal lymphadenectomy (p=0.48) between the two age groups. Elderly patients presented a more important number of postoperative complications (p=0.04) and these ones were more severe (p=0.03). There was no significant difference in postoperative mortality with 30-day mortality: 4.9%, n=4, versus 2.5%, n=2, (p=0.83); 60-day mortality: 6.2%, n=5, versus 2.5%, n=2, (p=0.61); and 90-day mortality was the same. Hospital LOS was longer for the elderly (14.9 days, CI95%[12.5;17.4] vs 11.9 days, CI95%[10.7;13.3], p<0.001)., Conclusion: Postoperative morbidity after neoadjuvant chemotherapy is more important in elderly patients. These data should be taken into account when considering the interest of preoperative treatment in elderly patients with resectable NSCLC., (Copyright © 2011 Elsevier Ireland Ltd.

Surgery of aspergilloma has been renowned to be technically challenging and has a high complication rate. We have already demonstrated an improved outcome as a result of a reduction in complex cases related to history of tuberculosis. In this paper we will evaluate whether this time trend has continued during recent years. Initial presentation and postoperative outcome of 33 patients who underwent surgical treatment between 1998 and 2009 were reviewed and compared with two previous reports (group 1: 55 patients from 1974 to 1991; group 2: 12 patients from 1992 to 1997). Underlying disease was tuberculosis in 15% of patients (57% in group 1, 17% in group 2), and 12% of patients had complex aspergillomas (80% in group 1, 41% in group 2). Postoperatively, there was no mortality (5% in group 1, 0% in group 2). Morbidity decreased progressively in terms of bleeding (44% in group 1, 9% in group 2, and 6% in recently, accrued patients), of pleural space problems (47%, 18% and 12%, respectively), and of prolonged hospital stay (32%, 8% and 6%, respectively). With a decreased postoperative complications rate after resection, contemporary surgery of aspergilloma is safe and offers satisfactory early and long-term results.

Background: The objective of this study was to better characterize prolonged air leak (PAL), defined as an air leak longer than 7 days, and to develop and validate a predictive model of this complication after pulmonary resection., Methods: All lung resections entered in Epithor, the French national thoracic database (French Society of Thoracic and Cardiovascular Surgery), were analyzed. Data collected between 2004 and 2008 (n=24,113) were used to build the model using backward stepwise variable selection, and the 2009 data (n=6,813) were used for external validation. The primary outcome was PAL. Results of the predictive model were used to propose a score: the index of PAL (IPAL)., Results: Prevalence of PAL after pulmonary resection was 6.9% (n=1,655) in the development data set. In the final model, 9 variables were selected: gender, body mass index, dyspnea score, presence of pleural adhesions, lobectomy or segmentectomy, bilobectomy, bulla resection, pulmonary volume reduction, and location on upper lobe. In the development data set, the C-index was 0.71 (95% confidence interval [CI], 0.70 to 0.72). At external validation, the C-index was 0.69 (95% CI, 0.66 to 0.72) and the calibration slope (ie, the agreement between observed outcomes and predictions) was 0.874 (<1). A score chart based on these analyses has been proposed. The formula to calculate the IPAL is the following: gender (F=0; M=4)-(body mass index-24)+2×dyspnea score+pleural adhesion (no=0; yes=4)+pulmonary resection (wedge=0; lobectomy or segmentectomy=7; bilobectomy=11; bulla resection=2; volume reduction=14)+location (lower or middle lobe=0; upper=4)., Conclusions: Surgeons can easily use the well-validated model to determine intraoperative preventive measures of PAL., (Copyright © 2011 The Society of Thoracic Surgeons.

Objective: The elderly is a fast-growing segment of the population and the number of oncogeriatric patients with lung cancer is expected to increase. The purpose of this study was to overview surgical habits for lung cancer in octogenarians., Methods: We used EPITHOR(®), the French national thoracic database, created in 2002 and including more than 135000 procedures from 93 institutions. We collected prospectively data concerning 622 patients 80 years or older, and 16461 patients younger than 80 years with lung cancer from 1 January 2004 to 31 December 2008. We compared patients' characteristics, lung-cancer presentation, and surgical treatment between these two groups., Results: Patients' characteristics analysis: the distribution by gender, body mass index, and forced expiratory volume was comparable for the two groups. American Society of Anesthesiologists (ASA) score (ASA 1 and 2: 59%, n=363 vs 71%, n=11543, p<0.0001) and performance status (PS) were worse for older patients (PS 0 and 1: 86%, n=470 vs 89%, n=12685, p<0.0001). Mean age (82.0, confidence interval (CI) 95% (81.9; 82.2)) and sex ratio (2.51, n=445 males) were stable for octogenarians across 5 years. Lung-cancer presentation analysis: in the elderly, stages I and II were of 71% (n=361) versus 66% (n=8735) in the younger group (p=0.001). Surgical treatment analysis: resections in octogenarians were pneumonectomy 10% (n=62) versus 15% (n=2409) for patients under 80 years, lobectomy 67% (n=415) versus 65% (n=10734), bilobectomy 4% (n=25) versus 5% (n=809), sub-lobar resection 11% (n=70) versus 8% (n=1355) (p=0.034). They underwent video-assisted thoracic surgery in 7% (n=43) versus 6% (n=917) (p=0.034). No lymph node dissection was more frequent in patients 80 years or older (8%, n=45) than in younger patients (5%, n=738) (p=0.0004)., Conclusion: Taken as a whole, octogenarians underwent more sub-lobar resections and less mediastinal lymph node dissections than younger patients. Effective management of lung cancer in older patients should be tailed to individual needs. Surgical treatment should not be denied on chronological age alone anymore., (Copyright © 2010 European Association for Cardio-Thoracic Surgery. Published by Elsevier B.V. All rights reserved.)

Objectives: The estimation of risk-adjusted in-hospital mortality is essential to allow each thoracic surgery team to be compared with national benchmarks. The objective of this study is to develop and validate a risk model of mortality after pulmonary resection., Methods: A total of 18,049 lung resections for non-small cell lung cancer were entered into the French national database Epithor. The primary outcome was in-hospital mortality. Two independent analyses were performed with comorbidity variables. The first analysis included variables as independent predictive binary comorbidities (model 1). The second analysis included the number of comorbidities per patient (model 2)., Results: In model 1 predictors for mortality were age, sex, American Society of Anesthesiologists score, performance status, forced expiratory volume (as a percentage), body mass index (in kilograms per meter squared), side, type of lung resection,extended resection, stage, chronic bronchitis, cardiac arrhythmia, coronary artery disease, congestive heart failure, alcoholism, history of malignant disease, and prior thoracic surgery. In model 2 predictors were age, sex, American Society of Anesthesiologists score, performance status, forced expiratory volume, body mass index, side, type of lung resection, extended resection, stage, and number of comorbidities per patient. Models 1 and 2 were well calibrated, with a slope correction factor of 0.96 and of 0.972, respectively. The area under the receiver operating characteristic curve was 0.784 (95% confidence interval, 0.76-0.8) in model 1 and 0.78 (95% confidence interval, 0.76-0.797) in model 2., Conclusions: Our preference is for the well-calibrated model 2 because it is easier to use in practice to estimate the adjusted postoperative mortality of lung resections for cancer., (Copyright © 2011 The American Association for Thoracic Surgery.

Objective: This study was undertaken to determine factors associated with in-hospital mortality among patients after general thoracic surgery and to construct a risk model., Methods: Data from a nationally representative thoracic surgery database were collected prospectively between June 2002 and July 2005. Logistic regression analysis was used to predict the risk of in-hospital death. A risk model was developed with a training set of data (two thirds of patients) and validated on an independent test set (one third of patients). Model fit was assessed by the Hosmer-Lemeshow test; predictive accuracy was assessed by the c-index., Results: Of the 15,183 original patients, 338 (2.2%) died during the same hospital admission. Within the data used to develop the model, these factors were found to be significantly associated with the occurrence of in-hospital death in a multivariate analysis: age, sex, dyspnea score, American Society of Anesthesiologists score, performance status classification, priority of surgery, diagnosis group, procedure class, and comorbid disease. The model was reliable (Hosmer-Lemeshow test 3.22; P = .92) and accurate, with a c-index of 0.85 (95% confidence interval 0.83-0.87) for the training set and 0.86 (95% confidence interval 0.83-0.89) for the test set of data. The correlation between the expected and observed number of deaths was 0.99., Conclusions: The validated multivariate model Thoracoscore, described in this report for risk of in-hospital death among adult patients after general thoracic surgery was developed with national data, uses only 9 variables, and has good performance characteristics. It appears to be a valid clinical tool for predicting the risk of death.
