Lung Cancer Surgery in Octogenarians: Implications and Advantages of Artificial Intelligence in the Preoperative Assessment. Healthcare (Basel) 2024; 12:803. [PMID: 38610225 PMCID: PMC11011722 DOI: 10.3390/healthcare12070803] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Revised: 04/02/2024] [Accepted: 04/04/2024] [Indexed: 04/14/2024] Open
Abstract
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.

Lung transplantation in patients with a history of anatomical native lung resection. Interact Cardiovasc Thorac Surg 2022; 35:6758257. [PMID: 36218975 PMCID: PMC9583932 DOI: 10.1093/icvts/ivac256] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Revised: 09/19/2022] [Accepted: 10/06/2022] [Indexed: 11/06/2022] Open
Abstract
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 01/2005 and 07/2020. The primary end-point was overall survival (Kaplan-Meier estimation). RESULTS Out of 2690 patients at 7 European centers, 26 (1%) patients (14 male; median age 33 years) underwent LTx after a previous anatomical lung resection. 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 (CF) or non-CF 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 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.

Rare indications for a lung transplant. A European Society of Thoracic Surgeons survey. Interact Cardiovasc Thorac Surg 2020; 31:638-643. [PMID: 33057713 DOI: 10.1093/icvts/ivaa165] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Revised: 06/04/2020] [Accepted: 07/09/2020] [Indexed: 11/14/2022] Open
Abstract
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.

Abstract
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.

Inflammatory Myofibroblastic Tumor After Lung Transplant-A Rare and Aggressive Complication: A Case Report. Transplant Proc 2019; 51:2991-2994. [PMID: 31611127 DOI: 10.1016/j.transproceed.2019.08.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2019] [Revised: 08/21/2019] [Accepted: 08/27/2019] [Indexed: 11/28/2022]
Abstract
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.

Abstract
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.

Abstract
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.

Colistin-based Treatment of Multidrug-resistant Gram-negative Bacterial Pulmonary Infections After Lung Transplantation. Transplant Proc 2018; 51:202-205. [PMID: 30661895 DOI: 10.1016/j.transproceed.2018.04.068] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2018] [Accepted: 04/13/2018] [Indexed: 01/06/2023]
Abstract
BACKGROUND Lung transplantation (LT) is a viable option for a select group of patients with end-stage lung disease. However, infections are a major complication after LT, accounting for significant morbidity and mortality. Several germs may be responsible; multidrug-resistant Gram-negative (MDR-GN) bacteria are emerging. Colistin is widely used in the treatment of these infections and is administered by inhalation and/or parenterally. At our institution, in patients with tracheostomy, colistin is administered by direct instillation in the airway during bronchoscopy. We reviewed a series of patients who underwent LT complicated by postoperative MDR-GN bacterial pulmonary infection. METHODS From January 2015 to May 2017, 26 lung transplants were performed. In the postoperative course, 14 (54%) developed MDR-GN bacterial infection; respiratory specimen culture, blood tests, and chest X-ray were considered. Colistin was the only antibiotic usable. Thirteen patients received intravenous (IV) colistin; in the subgroup of patients with tracheostomy, colistin was instilled directly in the airway, and 6 patients received inhaled colistin. RESULTS Seven patients needed tracheostomy. Pseudomonas aeruginosa was the predominant infection (86%), with Acinetobacter baumanii seen in 2 cases (14%). An early clinical-laboratory response was observed in 9 patients (64%). White blood cell count and C-reactive protein values improved (P = .02 and P = .001, respectively). A significant reduction in bacterial load was observed on microbiologic bronchoalveolar lavage specimens. CONCLUSION Colistin instilled directly in the airway did not show side effects. The combination of IV and inhaled/instilled colistin could be a useful treatment option for MDR-GN infections after LT.

Abstract
BACKGROUND Lung transplantation (LT) is only therapeutic option for patients affected by chronic respiratory failure. Chronic rejection, also known as bronchiolitis obliterans syndrome (BOS), is still the main cause of death and the most important factor that influences post-transplantation quality of life. Currently available therapies have not been proven to result in significant benefit in the prevention or treatment of BOS. Extracorporeal photopheresis (ECP) seems to reduce the rate of lung function decline in transplant recipients with progressive BOS. METHODS From 1991 until now, 239 LTs were performed at our center. Fifty-four patients (22.5%) developed BOS; 15 of these (27.7%) were treated with ECP. At the beginning of the treatment, all patients showed a mean decline of forced expiratory volume in 1 second (FEV1) from baseline values of 45.8% ± 17.2%; 2 patients were in long-term oxygen therapy. RESULTS Mean follow-up from November 2013 to June 2016 was 11.6 ± 7 months. Twelve patients (80%) showed lung function stabilization with an FEV1 range after treatment between -6% to +8% from the pre-treatment values. We did not report any adverse effects or increase of infections incidence. DISCUSSION ECP seems to be an effective and well-tolerated therapeutic option for LT patients with BOS in terms of stabilization of lung function and increased survival.

Abstract
BACKGROUND Acute kidney injury and chronic kidney failure are serious complications after lung transplantation. Glomerular filtration rate (GFR) is the primary indicator of renal function. Several equations have been proposed to evaluate the estimated GFR (eGFR). We compared three different equations to determine which has the better correlation with the development of acute and chronic renal failure in lung recipients. METHODS Twenty-two patients with a mean age of 54.4 ± 8.5 years underwent lung transplantation from 2010 to 2015. Thirteen (59%) had pulmonary fibrosis, 7 (32%) emphysema, 1 (4.5%) bronchiectasis, and 1 (4.5%) lymphangioleiomyomatosis. In all patients, eGFR was measured preoperatively using Cockcroft-Gault (CG), Modification of Diet in Renal Disease (MDRD), and Levey's Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations. In 20 patients (90%) eGFR was calculated at 1, 3, and 6 months. RESULTS According to CKD-EPI and MDRD, eight patients (36.3%) had preoperative reduction in eGFR, whereas 6 patients (27.2%) had preoperative reduction according to the CG (P = .04). The mean values were higher for the CG (103.2 vs. 102 vs. 94.4). Five patients (22.7%) developed perioperative acute renal failure requesting a dialysis treatment; four of these showed a preoperative eGFR to the highest CG (P = .05). At 1 and 6 months after lung transplantation, the CG, MDRD and CKD-EPI eGFR values were, respectively, 86.6, 84.1 and 76.6 mL/min/1.73m2 and 75.8, 72.7, and 72.3 mL/min/1.73m2. CKD-EPI eGFR values are more predictable than the other equations of AKI. CONCLUSIONS Preoperative assessment of eGFR using the MDRD and CKD-EPI seems to correlate better than the CG to the prediction of acute renal failure, whereas for the chronic form the three equations seem equivalent.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
Bilateral sequential lung transplantation (BSLT) is nowadays considered a valid therapeutic option for patients with end stage cystic fibrosis. We report our experience with 104 BSLTs in 101 patients. The overall survivals at 1, 3, 5, 10 years were 79%, 65%, 58%, and 42%, respectively. Perioperative mortality was 14.8% (n = 15). The leading causes of perioperative mortality were primary graft dysfunction and sepsis. Three patients were retransplanted owing to obliterative bronchiolitis. In 70 cases (69%), patients displayed ≥ 1 additional risk factors: previous lung resections, colonization by Burkholderia cepacia, diabetes, pneumothorax, or noninvasive ventilatory support. The mean preoperative 1-second forced expiratory volume of 0.69 ± 0.2 L (22%) increased to 85% at 1 year after the operation. The mean time on the waiting list was 12 ± 5 months. The 5 patients treated with extracorporeal membrane oxygenation before urgent transplantation were operated after 3, 5, 6, 30, and 3 days respectively. During the procedure, cardiopulmonary bypass was required in 33 patients (32%). Lung transplantation represents a unique opportunity to ameliorate the quality and improve the survival of patients affected by cystic fibrosis. Timing of referral and patient selection remain crucial for success.

Abstract
Airway complications (AC) are considered a serious cause of morbidity after lung transplantation (LT). Mechanical dilatation, laser vaporization, and silicone stent placement usually solve it. However, the use of self-expandable metallic stents (SENS) may be indicated in selected cases. Ten lung transplant recipients with AC were treated with SENS. Six patients underwent LT for cystic fibrosis, 2 for idiopathic pulmonary fibrosis, 1 for bronchiectasis, and 1 for emphysema. All patients received at least 1 treatment attempt with dilatation and silicone stent placement. The indications for SENS placement were the presence of a tortuous airway axis with stenosis and malacia of the right main bronchus in 5 patients; a long stenosis of the main and intermediate right bronchus involving the upper lobe orifice in 3 patients; or malacia that could not be stabilized with silicone stents in 3 cases. In 1 patient the procedure was bilateral. Functional improvement was immediate with a mean forced expiratory volume at 1 second (FEV(1)) gain of 35%. No stent dislocation was observed. Symptoms did not occur again in 5 patients with previous recurrent episodes of pneumonia. One stenosis, which was due to the ingrowth of granulation tissue occurred at 6 months after the procedure, was successfully treated with mechanical dilatation and laser vaporization. The deployment of SENS in a selected group of patients with AC after LT was easy, safe, and effective.
