Spontaneous ventilation (SV) video-assisted thoracic surgery (VATS) is aimed at offering less invasive alternatives to equivalent procedures under tracheal intubation with mechanical ventilation (MV) and its benefits have shown encouraging results in lung surgery. In addition, there is also growing interest in SV-VATS in mediastinum surgery. The rationale of SV in simpler mediastinum procedures is that MV anesthesia could be considered avoidable if SV anesthesia protocols could provide similar or even better results. On the other hand, for other indications involving more delicate patient subgroups, SV-VATS is aimed at offering a more rapid recovery with less anesthesia-related risks of cardio-respiratory complications. Based on encouraging initial results, SV is also being proposed for more demanding surgical procedures, including tracheal resection and esophagectomy. However, SV mediastinum surgery also implies contraindications, potential disadvantages and peculiar physiopathologic issues which must be clearly acknowledged. This perspective is aimed at providing a critical overview of the current knowledge about SV for mediastinum surgery, with a particular emphasis on the last 10 years of data about thymectomy, biopsy of mediastinal masses, thoracic sympathectomy, tracheal resection, pericardial window and esophagectomy.

Different prognostic scores have been applied to identify patients with non-small cell lung cancer who have a higher probability of poor outcomes. In this study, we evaluated whether the Naples Prognostic Score, a novel index that considers both inflammatory and nutritional values, was associated with long-term survival. This study presents a retrospective propensity score matching analysis of patients who underwent curative surgery for non-small cell lung cancer from January 2016 to December 2021. The score considered the following four pre-operative parameters: the neutrophil-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, serum albumin, and total cholesterol. The Kaplan–Meier method and Cox regression analysis were performed to evaluate the relationship between the score and disease-free survival, overall survival, and cancer-related survival. A total of 260 patients were selected for the study, though this was reduced to 154 after propensity score matching. Post-propensity Kaplan–Meier analysis showed a significant correlation between the Naples Prognostic Score, overall survival (p = 0.018), and cancer-related survival (p = 0.007). Multivariate Cox regression analysis further validated the score as an independent prognostic indicator for both types of survival (p = 0.007 and p = 0.010, respectively). The Naples Prognostic Score proved to be an easily achievable prognostic factor of long-term survival in patients with non-small cell lung cancer after surgical treatment.

Background/Objectives: The surveillance of patients with incidental pulmonary nodules overloads existing respiratory and lung cancer clinics, as well as multidisciplinary team meetings. In our clinical setting, until 2018, we had numerous patients with incidental pulmonary nodules inundating our outpatient clinics; therefore, the need to develop a novel service and dedicated clinical pathway arose. The aims of this study are to 1. provide (a) a model of setting up a novel pulmonary nodule service, and (b) a pragmatic clinical pathway to address the increasing need for surveillance of patients with incidental pulmonary nodules. 2. share real-world data from a dedicated pulmonary nodule service running in a tertiary setting with existing resources. Methods: A retrospective review of established processes and referral mechanisms to our tertiary pulmonary nodule service was conducted. We have also performed a retrospective collection and review of data for patients reviewed and discussed in our tertiary pulmonary nodule service between April 2018 and April 2024. Results: Our tertiary pulmonary nodule service (PNS) comprises a dedicated pulmonary nodule clinic, a nodule multidisciplinary team (MDT) meeting and a dedicated proforma referral system. Due to the current national health system legislation and relevant processes, patients are required to physically attend clinic appointments. There are various sources of referral, including other departments within the hospital, other hospitals, various specialties in primary care and self-referrals. Between 15 April 2018 and 15 April 2024, 2203 patients were reviewed in the pulmonary nodule clinic (903 females, 1300 males, mean age 64 ± 19 years). Of those patients, 65% (1432/2203) were current smokers. A total of 1365 new patients and 838 follow-up patients were reviewed in total. Emphysema was radiologically present in 72% of patients, and 75% of those (1189/1586) already had a confirmed diagnosis of chronic obstructive pulmonary disease (COPD). Coronary calcification was identified in 32% (705/2203), and 78% of those (550/705) were already known to cardiology services. Interestingly, 27% (368/1365) of the new patients were discharged following their first MDT meeting discussion, and 67% of these were discharged as the reason for their referral was an intrapulmonary lymph node which did not warrant any further action. Among all patients, 11% (246/2203) were referred to the multidisciplinary thoracic oncology service (MTOS) due to suspicious appearances/changes in their nodules that warranted further investigation, and from those, 37% were discharged (92/246) from the MTOS. The lung cancer diagnosis rate was 7% (154/2203). Conclusions: The applied pathway offers a pragmatic approach in setting up a service that addresses an increasing patient need. Its application is feasible in a tertiary care setting, and admin support is of vital importance to ensure patients are appropriately tracked and not lost to follow-up. Real-world data from pulmonary nodules services provide a clear overview and contribute to understanding patients’ characteristics and improving service provision.

Spontaneous ventilation lung surgery (SVLS) without intubation is aimed at avoiding adverse effects of mechanical ventilation lung surgery (MVLS) entailing one-lung mechanical ventilation through a double-lumen tracheal tube. This innovative strategy has evolved following the publication of a small randomized study of thoracoscopic pulmonary wedge resection carried out under spontaneous ventilation without tracheal intubation in fully awake patients. It now entails target-controlled sedation, the use of a laryngeal mask, and thoracic analgesia by intercostal or paravertebral blocks and has shown promise both in unicenter and multicenter studies, resulting in optimal feasibility and safety and highly satisfactory results, particularly in patients undergoing lung cancer resection and metastasectomy, lung biopsy for undetermined interstitial lung disease, lung volume reduction surgery for end-stage emphysema, and bullectomy for primary and secondary spontaneous pneumothorax. However, concerns and unresolved issues still exist regarding the advantages and disadvantages of SVLS as well as the identification of optimal indications. This perspective is aimed at providing a critical overview of the current knowledge about SVLS with emphasis on recent data comparing the results with those of MVLS published in the last 10 years.

The introduction of new therapeutic strategies and diagnostic tools in recent years has radically modified the management of patients with non-small cell lung cancer (NSCLC). Most of the guidelines recommend a multidisciplinary assessment of this kind of patient to achieve a \"tailored\" treatment. Herein, we report our institutional experience after the introduction of a multidisciplinary team (MDT) assessment for patients with NSCLC. We retrospectively evaluated patients who underwent surgery for suspected or confirmed NSCLC in our hospital from April 2021 to September 2024. We compared patients previously discussed within our multidisciplinary meetings (MDT group) to the ones who underwent surgery in the 21 months before its introduction (pre-MDT group). The primary outcome was the assessment of the congruity between clinical and pathological staging. Secondary endpoints were comparison about final histological diagnosis, surgical intent, and pathological stage. A total of 497 consecutive patients were enrolled in this study, with 255 (51.3%) belonging to the MDT group and 242 (48.7%) to the pre-MDT group. In the MDT group, there was a higher concordance between clinical and pathological staging, with only 8/255 cases of up- or downstaging (3.1%) versus 26/242 cases (10.7%) in the pre-MDT group (p < 0.001). Particularly, we recorded only 4 cases of upstaging in the MDT group versus 18 cases in the other one (p = 0.003). After the introduction of MDT, there was a significant reduction in surgery performed for benign lesions (18.8% versus 30.2%, p = 0.003) as well as surgery with diagnostic intent only (21.3% versus 30.2%, p = 0.048). Considering patients who underwent intentionally curative surgery, after MDT introduction, there was a significant increase in early-stage diagnosis (p = 0.003) and, among stage I patients, a significant increase in pT1a (15.1% versus 2.5%) together with a reduction in pT2a (23.8% versus 46.2%) with p = 0.007. The introduction of MDT in our institution was related to a better congruity between clinical and final pathological stages. Furthermore, MDT case discussion has led to a reduction of surgical procedures performed for either benign pulmonary lesions or diagnostic purposes in patients with advanced stages, thus allowing an increase of intentionally curative resections for early stages of thedisease.

Objectives: Robotic-Assisted Thoracic Surgery (RATS) has emerged as a viable alternative to traditional median sternotomy for patients with anterior mediastinal tumors suspected of having thymoma or those with Myasthenia Gravis (MG). While median sternotomy remains a widely accepted standard approach, RATS has gained popularity due to its potential benefits. Methods: We retrospectively reviewed our 5 years’ experience of performing 111 surgeries for patients with anterior mediastinal tumors and patients with MG suspected of having thymoma. We performed multivariate regression models to assess the association between main demographic and clinical variables and two primary outcomes: overall complications and hospital stay. Results: Out of 111 patients, 54 were men (48.6%) and 57 were women (51.4%). The majority of surgeries (n = 93) were performed by RATS (83.8%), while the remainder were performed by either median sternotomy (n = 15, 13.5%) or by other approaches (n = 3, 2.7%). Sixty-five patients were diagnosed with thymoma (58.6%), with 96.9% R0 resection. Sixty-five patients underwent left-sided surgery (58.6%), and thirty-one underwent right-sided surgery (27.9%). The conversion rate was 2.5%. The rate of postoperative complications was 8.1 without perioperative mortality. The median hospital stay was 4.62 days, but it was significantly shorter in the RATS compared to the median sternotomy group (mean 3.64 vs. 10.67 days, p = 0.040). Conclusions: Our results suggest that RATS for patients with anterior mediastinal tumors suspected of having thymoma or for those with MG is safe and technically feasible and may be the preferred surgical approach for selected patients, whereas traditional median sternotomy remains the preferred choice for more locally advanced tumors.

Solitary pulmonary nodules (SPNs) are a diagnostic and therapeutic challenge for thoracic surgeons. Although such lesions are usually benign, the risk of malignancy remains significant, particularly in elderly patients, who represent a large segment of the affected population. Surgical treatment in this subset, which usually presents several comorbidities, requires careful evaluation, especially when pre-operative biopsy is not feasible and comorbidities may jeopardize the outcome. Radiomics and artificial intelligence (AI) are progressively being applied in predicting malignancy in suspicious nodules and assisting the decision-making process. In this study, we analyzed features of the radiomic images of 71 patients with SPN aged more than 75 years (median 79, IQR 76–81) who had undergone upfront pulmonary resection based on CT and PET-CT findings. Three different machine learning algorithms were applied—functional tree, Rep Tree and J48. Histology was malignant in 64.8% of nodules and the best predictive value was achieved by the J48 model (AUC 0.9). The use of AI analysis of radiomic features may be applied to the decision-making process in elderly frail patients with suspicious SPNs to minimize the false positive rate and reduce the incidence of unnecessary surgery.

Data and results of 646 patients operated on at the department of Thoracic Surgery of the Tor Vergata University Policlinic in Rome between February 2019 and March 2021 were retrospectively analyzed. Patients were divided in 2 groups: one operated on during the COVID-19 pandemic (pandemic group) and another during the previous non-pandemic 12 months (non-pandemic group). Primary outcome measure was COVID-19 infection-free rate. Three patients developed mild COVID-19 infection early after surgery resulting in an estimated COVID-19 infection-free rate of 98%. At intergroup comparisons (non-pandemic vs. pandemic group), a greater number of patients was operated before the pandemic (352 vs. 294, p = 0.0013). In addition, a significant greater thoracoscopy/thoracotomy procedures rate was found in the pandemic group (97/151 vs. 82/81, p = 0.02) and the total number of chest drainages (104 vs. 131, p = 0.0001) was higher in the same group. At surgery, tumor size was larger (19.5 ± 13 vs. 28.2 ± 21; p < 0.001) and T3-T4/T1-T2 ratio was higher (16/97 vs. 30/56; p < 0.001) during the pandemic with no difference in mortality and morbidity. In addition, the number of patients lost before treatment was higher in the pandemic group (8 vs. 15; p = 0.01). Finally, in 7 patients admitted for COVID-19 pneumonia, incidental lung (N = 5) or mediastinal (N = 2) tumors were discovered at the chest computed tomography. Estimated COVID-19 infection free rate was 98% in the COVID-19 pandemic group; there were less surgical procedures, and operated lung tumors had larger size and more advanced stages than in the non-pandemic group. Nonetheless, hospital stay was reduced with comparable mortality and morbidity. Our study results may help implement efficacy of the everyday surgical care.

Awake thoracic surgery is a new surgical field that is set to expand in the near future. Employing sole epidural or local anaesthesia in fully awake patients renders many thoracic surgical procedures doable with less invasiveness and general anaesthesia related adverse effects can be avoided. This, in turn, facilitates fast track surgery and improves cost-effectiveness of treatment procedures. The book explains issues relevant to awake thoracic surgery including postoperative immunologic and stress-hormone responses, lung volume reduction surgery, pulmonary resections and thymectomy. This Ebook should be useful to readers interested in a comprehensive reference work on this intriguing minimally invasive surgical option.

Thoracoscopic surgical biopsy has shown excellent histological characterization of undetermined interstitial lung diseases, although the morbidity rates reported are not negligible. In delicate patients, interstitial lung disease and restrictive ventilatory impairment morbidity are thought to be due at least in part to tracheal intubation with single-lung mechanical ventilation; therefore, spontaneous ventilation thoracoscopic lung biopsy (SVTLB) has been proposed as a potentially less invasive surgical option. This systematic review summarizes the results of SVTLB, focusing on diagnostic yield and operative morbidity. A systematic search for original studies regarding SVTLB published between 2010 to 2023 was performed. In addition, articles comparing SVTLB to mechanical ventilation thoracoscopic lung biopsy (MVTLB) were selected for a meta-analysis. Overall, 13 studies (two before 2017 and eleven between 2018 and 2023) entailing 675 patients were included. Diagnostic yield ranged from 84.6% to 100%. There were 64 (9.5%) complications, most of which were minor. There was no 30-day operative mortality. When comparing SVTLB to MVTLB, the former group showed a significantly lower risk of complications (p < 0.001), whereas no differences were found in diagnostic accuracy. The results of this review suggest that SVTLB is being increasingly adopted worldwide and has proven to be a safe procedure with excellent diagnostic accuracy.
