The general world population is aging and patients are often diagnosed with early-stage lung cancer at an advanced age. Several studies have shown that age is not itself a contraindication for lung cancer surgery, and therefore, more and more octogenarians with early-stage lung cancer are undergoing surgery with curative intent. However, octogenarians present some peculiarities that make surgical treatment more challenging, so an accurate preoperative selection is mandatory. In recent years, new artificial intelligence techniques have spread worldwide in the diagnosis, treatment, and therapy of lung cancer, with increasing clinical applications. However, there is still no evidence coming out from trials specifically designed to assess the potential of artificial intelligence in the preoperative evaluation of octogenarian patients. The aim of this narrative review is to investigate, through the analysis of the available international literature, the advantages and implications that these tools may have in the preoperative assessment of this particular category of frail patients. In fact, these tools could represent an important support in the decision-making process, especially in octogenarian patients in whom the diagnostic and therapeutic options are often questionable. However, these technologies are still developing, and a strict human-led process is mandatory.

Objectives: History of anatomical lung resection complicates lung transplantation (LTx). Our aim was to identify indications, intraoperative approach and outcome in these challenging cases in a retrospective multicentre cohort analysis., Methods: Members of the ESTS Lung Transplantation Working Group were invited to submit data on patients undergoing LTx after a previous anatomical native lung resection between January 2005 and July 2020. The primary end point was overall survival (Kaplan-Meier estimation)., Results: Out of 2690 patients at 7 European centres, 26 (1%) patients (14 males; median age 33 years) underwent LTx after a previous anatomical lung resection. The median time from previous lung resection to LTx was 12 years. The most common indications for lung resection were infections (n = 17), emphysema (n = 5), lung tumour (n = 2) and others (n = 2). Bronchiectasis (cystic fibrosis or non-cystic fibrosis related) was the main indication for LTx (n = 21), followed by COPD (n = 5). Two patients with a previous pneumonectomy underwent contralateral single LTx and 1 patient with a previous lobectomy had ipsilateral single LTx. The remaining 23 patients underwent bilateral LTx. Clamshell incision was performed in 12 (46%) patients. Moreover, LTx was possible without extracorporeal life support in 13 (50%) patients. 90-Day mortality was 8% (n = 2) and the median survival was 8.7 years., Conclusions: The history of anatomical lung resection is rare in LTx candidates. The majority of patients are young and diagnosed with bronchiectasis. Although the numbers were limited, survival after LTx in patients with previous anatomical lung resection, including pneumonectomy, is comparable to reported conventional LTx for bronchiectasis., (© The Author(s) 2022.

Severe acute respiratory syndrome coronavirus 2 disease 2019 (COVID-19) has rapidly spread worldwide since December 2019. An acute respiratory distress syndrome develops in a relevant rate of patients, who require hospitalization. Among them, a nonnegligible rate of 9.8% to 15.2% of patients requires tracheal intubation for invasive ventilation. We report the case of a pneumomediastinum and subcutaneous emphysema developing in a COVID-19 patient secondary to postintubation tracheal injury. The management of COVID-19 patients can be challenging due to the risk of disease transmission to caregivers and epidemic spread. We performed a bedside tracheal injury surgical repair, after failure of conservative management, with resolution of pneumomediastinum and subcutaneous emphysema and improvement of the patient's conditions., (© 2020 by The Society of Thoracic Surgeons Published by Elsevier.)

Objectives: The European Society of Thoracic Surgeons Lung Transplantation Working Group promoted a survey to evaluate overall survival in a large cohort of patients receiving lung transplants for rare pulmonary diseases., Methods: We conducted a retrospective multicentre study. The primary end point was overall survival; secondary end points were survival of patients with the most common diagnoses in the context of rare pulmonary diseases and chronic lung allograft dysfunction (CLAD)-free survival. Finally, we analysed risk factors for overall survival and CLAD-free survival., Results: Clinical records of 674 patients were extracted and collected from 13 lung transplant centres; diagnoses included 46 rare pulmonary diseases. Patients were followed for a median of 3.1 years. The median survival after a lung transplant was 8.5 years. The median CLAD-free survival was 8 years. The multivariable analysis for mortality identified CLAD as a strong negative predictor [hazard ratio (HR) 6.73)], whereas induction therapy was a protective factor (HR 0.68). The multivariable analysis for CLAD occurrence identified induction therapy as a protective factor (HR 0.51). When we stratified patients by CLAD occurrence in a Kaplan-Meier plot, the survival curves diverged significantly (log-rank test: P < 0.001). Patients with rare diseases who received transplants had chronic rejection rates similar to those of the general population who received transplants., Conclusions: We observed that overall survival and CLAD-free survival were excellent. We support the practice of allocating lungs to patients with rare pulmonary diseases because a lung transplant is both effective and ethically acceptable., (© The Author(s) 2020.

Introduction: After lung transplantation (LTx), infections caused by multidrug-resistant (MDR) bacteria are frequent and difficult to treat. Some new antibiotics seem to be effective in treating these infections., Material and Methods: We describe our experience in treatment of Klebsiella pneumoniae MDR and Pseudomonas aeruginosa MDR infections with ceftazidime-avibactam (CEF-AVI) and ceftazidime-tazobactam (CEFT-TAZ) in patients who underwent LTx., Results: In 3 patients who underwent double LTx and in 4 patients who underwent single LTx, strains of K. pneumoniae and P. aeruginosa were isolated from bronchoalveolar lavage. All patients showed worsening of respiratory functions, increasing in inflammation indexes, and, in some cases, onset of pulmonary consolidation. P. aeruginosa was treated with CEFT-TAZ for 10 days average (7-15 days) and K. pneumoniae with CEF-AVI for 14 days average (4-24 days). One patient developed a septic state caused by K. pneumoniae, requiring 24 days of therapy. None had shown side effects caused by drugs administration. One patient died after 15 days from lung transplant owing to primary graft dysfunction., Conclusions: CEF-AVI and CEFT-TAZ seems to be effective in treatment of infections caused by MDR bacteria after lung transplant., (Copyright © 2020 Elsevier Inc.

Introduction: Malignant diseases are well-known complications after lung transplantation (LT). Among these, inflammatory myofibroblastic tumor (IMT) is a rare neoplasm with a not well-known and often aggressive biological behavior., Material and Methods: We hereby describe 2 cases of cystic fibrosis patients who underwent bilateral sequential LT (BSLT) complicated by IMT., Results: A 26-year-old man presented a right endobronchial lesion 6 months after BSLT. Two consecutive fiber bronchoscopic biopsies showed granulation tissue. For the persistent lesion growth, the patient underwent a transthoracic biopsy showing histologic diagnosis of IMT. Therefore, he underwent to right pneumonectomy that was unfortunately complicated after 6 months with a late bronchopleural fistula and empyema with exitus 6 months later. A 31-year-old woman 1 year after BSLT presented with a left voluminous pleural-parenchymal lesion; the histologic examination after biopsy revealed an IMT. She underwent a removal of the lesion with a macroscopic R0 resection. Histologic, immunophenotypic, and cytogenetic examinations showed a strong overexpression of anaplastic lymphoma kinase requiring biological adjuvant therapies; however, the patient refused it. Four years later, she presented a recurrence treated with debulking procedure and adjuvant radiotherapy. At last follow-up, the patient was alive with stable disease and optimal graft function., Conclusions: Although IMT is a rare complication after lung transplant, to obtain a careful diagnosis, an early and aggressive treatment is mandatory., (Copyright © 2019 The Authors.

A clear cell tumor is a histological entity that rarely originates outside of the kidney. We describe a rare case of a clear cell tumor of the lung, also known as "sugar cancer," that occurred in a 74 year-old male patient, and perform a brief literature review. This report highlights the importance of an adequate disease management team, including surgeons, oncologists, and pathologists, to identify the best therapeutic approach to improve survival rates and the quality of life of patients affected by this rare disease., (© 2019 The Authors.

Chronic obstructive pulmonary disease (COPD) is the major causes of disability and mortality. The efficacy of maximal medical treatment, although effective at the early stages of the disease, becomes limited when extensive alveolar destruction is the main cause of respiratory failure. At this stage of the disease more aggressive options, when feasible, should be considered. Lung transplantation and lung volume reduction surgery (LVRS) are currently available for a selected group of patients. Endoscopic alternatives to LVRS have progressively gained acceptance and are currently employed in patients with COPD. They promote lung deflation searching the same outcome as LVRS in terms of respiratory mechanics, ameliorating the distressing symptom of chronic dyspnea by decreasing the physiological dead space., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Background: This retrospective study is designed to evaluate factors affecting survival in a population of patients receiving pulmonary metastasectomy after gynecologic cancers., Methods: Nineteen patients with isolated lung metastases (one or two) were surgically treated with R0 resection. Four of them underwent lobectomies., Results: Six patients (31.6%) received adjuvant therapy and 11 (58%) experienced recurrences after metastasectomy. Five- and ten-year survival were 40.9% and 31.4%, respectively. Five-year survival in patients receiving adjuvant therapy was 52.4%. At multivariate analysis factors negatively influencing survival were a disease-free interval (DFI) of less than 24 months and recurrence after pulmonary metastasectomy., Conclusions: Pulmonary resection for metastatic gynecologic cancer is feasible and effective; adequate selection of patients is mandatory to achieve satisfactory results and long-term survival., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Background: Complete resection for stage II thymic tumors can be easily accomplished even if the capsula and adjacent mediastinal tissue are macroscopically involved; however, also at this stage, recurrence may occur, particularly for B2, B3 and thymic carcinoma. The criteria for the administration of adjuvant therapy remain controversial and it is unclear whether patients at this stage may benefit from it. We reviewed a series of patients at this stage receiving adjuvant chemo-radiotherapy (chemo-RT) based on histology., Methods: Eighty-eight consecutive patients with stage II thymic tumors were reviewed; 59 patients (67%) with B thymoma or thymic carcinoma received adjuvant treatment with mediastinal irradiation (40-55 Gy), chemotherapy (CH) (PAC regimen) or a combination of both., Results: Complete resection was achieved in all patients. Fifty-four patients (61%) received post-operative chemo-RT, 2 (2%) patients received adjuvant CH only and 3 (3%) post-operative RT only; they all had B2, B3 histology or thymic carcinoma. The median follow up was 107±83 months. 5-year and 10-year survival were 96%±2% and 83.4%±5%. Recurrence was observed in 5 patients (5.7%). Disease-free 5 and 10-year survival was 94%±2% and 92%±3% respectively. Five patients (5.7%) had recurrence., Conclusions: The administration of adjuvant chemo-RT to patients with stage II type B thymoma and thymic carcinoma contributes to reduce the recurrence rate and to increase long-term survival., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Objectives: Brain death (BD) is associated with various systemic responses and a cascade of inflammatory reactions. It is still unknown how the time interval from BD to cold preservation (CP) affects outcome after lung transplantation (LTx). This report investigates the impact of the time interval from BD to CP on long-term outcome in LTx., Methods: We reviewed 250 consecutive recipients who underwent LTx at our institution between January 2000 and December 2011. In Group I (n = 212), the time interval from BD to CP was <24 h, and in Group II (n = 38) >24 h. Cox proportional hazard regression analysis was performed to determine the risk factors affecting survival., Results: The median time from BD to CP was 18.6 h (range 9-65). The rate of postoperative complications was comparable (P = 0.8). The 30-day mortality rate was 7.5% in Group I and 0% in Group II. The 5-year survival rate was better in Group II [70% (95% CI: 48.5-83.8%)] than in Group I [66% (95% CI: 58.3-72.5%)] without statistical significance (P = 0.3). Intraoperative extracorporeal membrane oxygenation (ECMO) use was identified as a significant risk factor for survival [HR = 1.7, (95% CI: 1.1-2.6), P = 0.01]., Conclusion: In our cohort, the time interval from BD to CP had no impact on long-term outcome after LTx., (© The Author 2016.

Objectives: Acute lung rejection (ALR) is a relatively frequent complication during the first year after lung transplantation (LT). It is characterized by perivascular/bronchial mononuclear inflammation mediated by several cytokines. The aim of our study was to monitor a panel of cytokines extracted from the bronchoalveolar lavage (BAL) during the first year after LT and correlate them with clinical ALR., Methods: Twenty double lung transplant recipients were prospectively assessed. Fifteen (75%) were affected by cystic fibrosis (CF). BAL was collected at seven different steps (pretransplant, immediately post-transplant, after 1 week, 1, 3, 6 months and 1 year). A panel of six cytokines was analysed: tumour necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, IL-8, macrophage inflammatory protein (MIP)-1α and IL-10. We correlated the cytokine levels with clinical ALR episodes, bacterial and cytomegalovirus (CMV) infections., Results: One hundred and thirty-eight BAL samples were collected and analysed. In CF patients, the levels of proinflammatory cytokines significantly dropped immediately after the transplant while they increased in all the other patients. Four patients (20%) died between 6 months and 1 year. Nine patients (45%) showed one clinical ALR episode within 6 months; in 6 (30%) patients, a bacterial pneumonia was diagnosed and 5 (25%) developed CMV infection. No differences with the complication rate between CF and non-CF patients were observed. During the infection episodes, all proinflammatory cytokines increased with low levels of IL-10; in case of ALR, levels of IL-1β and MIP-1α increased significantly (P = 0.01 and P < 0.0001), IL-10 levels were higher compared with the infection episodes (P = 0.03). No significant changes were observed for TNF-α, IL-6 and IL-8., Conclusions: The BAL cytokine profile (IL-1β, MIP-1α and IL-10) seems useful to differentiate ALR and infections., (© The Author 2014.

Inflammatory myofibroblastic tumors (IMTs) are rare neoplasms that can involve the airway. Recent studies have shown their malignant behavior with local recurrence and potential metastatic spread; half of the cases are associated with anaplastic lymphoma kinase gene rearrangement. Complete surgical resection is recommended, when feasible. We present a case of a 26-year-old woman admitted to our institution with severe respiratory failure; she was affected with primary IMT of the trachea and underwent complete surgical resection.

Uniportal video-assisted thoracoscopy (VATS) has gaining a special place in the thoracic surgery scenario; nowadays even major pulmonary resections can be performed through this approach. We hereby review our initial experience with uniportal VAT lobectomy, performed passing directly from the open approach to a single port approach. We attempted 26 lobectomies through VATS with a single incision of about 5 cm and 22 of them were completed: eight left lower lobectomies, six right upper lobectomies, five left upper lobectomies and three right lower lobectomies. At pathological staging all but four patients were stage I; three patients were T2N1M0 and one had a micrometastasis in a lymph node of station 7 (T1N2M0-Stage IIIA) and they all underwent adjuvant chemotherapy. No perioperative mortality was observed. One patient had a myocardial infarction in the first postoperative day requiring placement of four stents and another one required thoracentesis after drainage removal. The mean time for drainage removal was 3 days and the length of hospitalization was 4.2±1.1. Pain as measured by the visual analogical scale (VAS) scale was graded as 4.9, 2.6 and 0.5 during the first postoperative day, at discharge and after 1 month respectively.
