Abstract
PURPOSE The aim of this retrospective study was to evaluate the medium-term clinical and radiographic results of current generation metal-on-metal resurfacing prostheses performed through anterolateral approach. MATERIALS AND METHODS Fifty-seven hips in 52 patients underwent resurfacing arthroplasty. Two patients died from unrelated causes, leaving 55 hips in 35 males (3 bilateral) and 15 females (2 bilateral), with a mean age at surgery of 56.2 years (range, 27-70 years). Clinical and radiographic assessment was carried out preoperatively and at follow-up in all the survived cases. The cumulative survival rate was determined according to the method of Kaplan-Meier. RESULTS At a mean follow-up of 5.2 years (range, 1.8-9.1 years), 2 HRs of the same female patient were revised because of early loosening of the acetabular component. Deep venous thrombosis and transient femoral nerve palsy occurred both in 1 case. No specific complications of HR were observed. Average Harris hip score improved significantly from 59.8 points (range, 30.4-90.6) preoperatively to 93.7 points (range, 53-100) at the latest examination. Neck narrowing showed an average of 3.27%, but it never exceeded 10%. Nonprogressive acetabular radiolucencies and osteolysis were detected both in 2 hips. A high rate of patients (32, 60.4%) developed heterotopic ossifications, although low-grade in most cases (27, 84.4%). The cumulative survival rate at 9.1 years with revision for any reason as the end point was 93.0%. CONCLUSIONS The early clinical and radiographic results of modern metal-on-metal hip resurfacing performed through an anterolateral approach are promising, but longer-term follow-up studies are necessary.

Consensus clustering methodology to improve molecular stratification of non-small cell lung cancer. Sci Rep 2023; 13:7759.

Abstract
Recent advances in machine learning research, combined with the reduced sequencing costs enabled by modern next-generation sequencing, paved the way to the implementation of precision medicine through routine multi-omics molecular profiling of tumours. Thus, there is an emerging need of reliable models exploiting such data to retrieve clinically useful information. Here, we introduce an original consensus clustering approach, overcoming the intrinsic instability of common clustering methods based on molecular data. This approach is applied to the case of non-small cell lung cancer (NSCLC), integrating data of an ongoing clinical study (PROMOLE) with those made available by The Cancer Genome Atlas, to define a molecular-based stratification of the patients beyond, but still preserving, histological subtyping. The resulting subgroups are biologically characterized by well-defined mutational and gene-expression profiles and are significantly related to disease-free survival (DFS). Interestingly, it was observed that (1) cluster B, characterized by a short DFS, is enriched in KEAP1 and SKP2 mutations, that makes it an ideal candidate for further studies with inhibitors, and (2) over- and under-representation of inflammation and immune systems pathways in squamous-cell carcinomas subgroups could be potentially exploited to stratify patients treated with immunotherapy.

SKP2 drives the sensitivity to neddylation inhibitors and cisplatin in malignant pleural mesothelioma. JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2022; 41:75. [PMID: 35197103 PMCID: PMC8864928 DOI: 10.1186/s13046-022-02284-7] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Accepted: 02/10/2022] [Indexed: 12/12/2022]
Abstract
Background The combination of pemetrexed and cisplatin remains the reference first-line systemic therapy for malignant pleural mesothelioma (MPM). Its activity is moderate because of tumor aggressiveness, immune-suppressive environment and resistance to chemotherapy-induced immunogenic cell death (ICD). Preliminary and limited findings suggest that MPM cells have deregulated ubiquitination and proteasome activities, although proteasome inhibitors achieved disappointing clinical results. Methods Here, we investigated the role of the E3-ubiquitin ligase SKP/Cullin/F-box (SCF) complex in cell cycle progression, endoplasmic reticulum (ER)/proteostatic stress and ICD in MPM, and the therapeutic potential of the neddylation/SCF complex inhibitor MLN4924/Pevonedistat. Results In patient-derived MPM cultures and syngenic murine models, MLN4924 and cisplatin showed anti-tumor effects, regardless of MPM histotype and BAP1 mutational status, increasing DNA damage, inducing S- and G2/M-cell cycle arrest, and apoptosis. Mechanistically, by interfering with the neddylation of cullin-1 and ubiquitin-conjugating enzyme UBE2M, MLN4924 blocks the SCF complex activity and triggers an ER stress-dependent ICD, which activated anti-MPM CD8+T-lymphocytes. The SKP2 component of SCF complex was identified as the main driver of sensitivity to MLN4924 and resistance to cisplatin. These findings were confirmed in a retrospective MPM patient series, where SKP2 high levels were associated with a worse response to platinum-based therapy and inferior survival. Conclusions We suggest that the combination of neddylation inhibitors and cisplatin could be worth of further investigation in the clinical setting for MPM unresponsive to cisplatin. We also propose SKP2 as a new stratification marker to determine the sensitivity to cisplatin and drugs interfering with ubiquitination/proteasome systems in MPM.

Expert consensus on resection of chest wall tumors and chest wall reconstruction. Transl Lung Cancer Res 2022; 10:4057-4083.

Abstract
Chest wall tumors are a relatively uncommon disease in clinical practice. Most of the published studies about chest wall tumors are usually single-center retrospective studies, involving few patients. Therefore, evidences regarding clinical conclusions about chest wall tumors are lacking, and some controversial issues have still to be agreed upon. In January 2019, 73 experts in thoracic surgery, plastic surgery, science, and engineering jointly released the Chinese Expert Consensus on Chest Wall Tumor Resection and Chest Wall Reconstruction (2018 edition). After that, numerous experts put forward new perspectives on some academic issues in this version of the consensus, pointing out the necessity to further discuss the points of contention. Thus, we conducted a survey through the administration of a questionnaire among 85 experts in the world. Consensus has been reached on some major points as follows. (I) Wide excision should be performed for desmoid tumor (DT) of chest wall. After excluding the distant metastasis by multi-disciplinary team, solitary sternal plasmacytoma can be treated with extensive resection and adjuvant radiotherapy. (II) Wide excision with above 2 cm margin distance should be attempted to obtain R0 resection margin for chest wall tumor unless the tumor involves vital organs or structures, including the great vessels, heart, trachea, joints, and spine. (III) For patients with chest wall tumors undergoing unplanned excision (UE) for the first time, it is necessary to carry out wide excision as soon as possible within 1–3 months following the previous surgery. (IV) Current Tumor Node Metastasis staging criteria (American Joint Committee on Cancer) of bone tumor and soft tissue sarcoma are not suitable for chest wall sarcomas. (V) It is necessary to use rigid implants for chest wall reconstruction once the maximum diameter of the chest wall defect exceeds 5 cm in adults and adolescents. (VI) For non-small cell lung cancer (NSCLC) invading the chest wall, wide excision with neoadjuvant and/or adjuvant therapy are recommended for patients with stage T3-4N0-1M0. As clear guidelines are lacking, these consensus statements on controversial issues on chest wall tumors and resection could possibly serve as further guidance in clinical practice during the upcoming years.

Abstract
Coronavirus disease 2019 (COVID-19) is an acute respiratory disease that has rapidly spread to become a global pandemic. Bronchoscopy is clearly a high-risk manoeuvrer, so to continue endoscopic activity safely it was necessary to make many changes. We created different ways to access and exit the endoscopy theatre and reinforced our dressing/undressing regimens as well as equipment cleaning techniques. To prevent aerosol dispersion we used a bag valve mask with an antibacterial-antiviral filter, introducing the flexible bronchoscope orally rather than through the nose. For procedures with increased contagious risk a nasopharyngeal swab was required. From the date of the first case of COVID-19 in our hospital to December 31 2020, we performed 1027 bronchoscopies, in both negative and positive patients. No outbreaks occurred within the staff and no patients are known to have developed COVID-19 after a procedure. Our experience underscores how it is possible to continue endoscopic activity safely.

Abstract
The possibility of using three-dimensional reconstructions as an intraoperative aid to thoracic surgeons has not yet been fully explored. With this in mind, we developed a technology based on a three-dimensional virtual model of lungs obtained from lung computed tomography scans, the Hyper-Accuracy Three-Dimensional reconstruction (HA3D™), which aids the surgeon during surgery. We tested this technology while performing a uniportal video-assisted thoracic surgery right upper lobectomy for lung cancer.

Which Is the Best Treatment in Recurrent Thymoma? A Systematic Review and Meta-Analysis. Cancers (Basel) 2021; 13:cancers13071559. [PMID: 33805310 PMCID: PMC8036834 DOI: 10.3390/cancers13071559] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Revised: 03/17/2021] [Accepted: 03/19/2021] [Indexed: 11/16/2022] Open
Abstract
Simple Summary Thymomas are rare tumors developing in the anterior mediastinum. Despite their usually indolent behavior, recurrence might occur in 5–15% of cases. Considering their rarity, the optimal recurrence treatment is still unclear even if surgical treatment seems to ensure a remarkable long-term survival compared to chemo- or radiotherapy. However, the major part of studies report low patient numbers, and it is difficult to plan prospective studies due to tumor characteristics, long follow-up and rarity of cases. For these reasons, we planned a systematic review and meta-analysis comparing surgical treatment with other therapies, in order to identify the best treatment for these patients. Our meta-analysis included more than 700 patients showing that surgical treatment seems to be associated with a better survival compared to other treatments and should be considered where feasible. Abstract Background: Optimal recurrent thymoma management remains arguable because of limited patient numbers, and relatively late and variable recurrence patterns. Given the absence of high-quality evidence and relatively small study cohorts, we performed a quantitative meta-analysis to determine the outcome of surgical and non-surgical approaches assessing the five-year overall survival (5y overall survival (OS)) in patients with recurrent thymoma. Methods: We performed a comprehensive literature search and analysis according to PRISMA guidelines of studies published from 1 January 1980 until 18 June 2020 from PubMed/MEDLINE, EMBASE, and Scopus. We included studies with the cohorts’ superior to 30 patients describing recurrent thymoma treatment, comparing surgical and non-surgical approaches reporting survival data. Results: Literature search revealed 3017 articles. Nine studies met all inclusion criteria and were selected for the meta-analysis. The recurrences were local/regional in 73–98% of cases and multiple in 49–72%. After treatment, 5y OS ranged from 48–77% and 10y OS from 37–51%. The quantitative meta-analysis showed a better outcome comparing surgical vs other treatments. Two studies showed statistically significant risk differences in the 5y OS favoring complete resection. After pooling results of seven studies using the random model, the combined 5y OS risk difference was 0.39, with lower and upper limits of 0.16 and 0.62, respectively (p = 0.001), and a moderate heterogeneity among studies (p = 0.098, I2 = 43.9%). Definitive conclusions could not be drawn regarding the prognostic impact of myasthenia gravis, histology, and patterns of relapse reported in literature. Conclusions: Surgical treatment after thymoma recurrence is associated with a significant better 5y OS; therefore, surgical resection should be preferred in all technically feasible cases.

Results of Surgical Resection of Locally Advanced Pulmonary Neuroendocrine Tumors. Ann Thorac Surg 2020; 112:405-414.

Abstract
BACKGROUND Pulmonary neuroendocrine tumors include well-differentiated and poorly differentiated histology for which cell type has proved to be a determinant of survival in many studies. In patients diagnosed with bronchial carcinoid and large cell neuroendocrine carcinoma (LCNEC), surgery is the treatment of choice even in the case of locally advanced disease with lymph node involvement. METHODS We retrospectively analyzed patients undergoing anatomic lung resection for bronchial carcinoid or LCNEC with lymph node involvement (N1/N2) at the final pathologic examination (pN+). Characteristics of patients and differences in overall survival and disease-free survival are presented according to tumor type. Overall survival of distinct histologic groups was compared with survival in our institutional experience in stage I patients, without nodal involvement (pN0). RESULTS In all, 325 patients underwent surgical resection for neuroendocrine tumors; 89 patients had nodal involvement. Five-year survival was 89% in pN+ bronchial carcinoid both for typical carcinoid and atypical carcinoid but worse for pN+ LCNEC (47%). Cell type did not influence the prognosis in N0 disease, and no differences in survival were evident between N0 and N+ in the bronchial carcinoid group. In the group of LCNEC, 5-year overall survival was much worse for pN+ LCNEC (47%) compared with pN0 LCNEC (91%). CONCLUSIONS Bronchial carcinoids have the best prognosis, and surgery remains the treatment of choice for both early and locally advanced disease. On the contrary, aggressive forms (LCNEC) with lymph nodal metastasis have a poor prognosis, and they need to be treated with an aggressive multidisciplinary approach.

Protease inhibitors elicit anti-inflammatory effects in CF mice with Pseudomonas aeruginosa acute lung infection. Clin Exp Immunol 2020; 203:87-95.

Abstract
Pseudomonas aeruginosa is the major respiratory pathogen in patients with cystic fibrosis (CF). P. aeruginosa-secreted proteases, in addition to host proteases, degrade lung tissue and interfere with immune processes. In this study, we aimed at evaluating the possible anti-inflammatory effects of protease inhibitors Marimastat and Ilomastat in the treatment of P. aeruginosa infection. Lung infection with the P. aeruginosa PAO1 strain was established in wild-type and cystic fibrosis transmembrane conductance regulator (CFTR) knock-out C57BL/6 mice expressing a luciferase gene under control of bovine interleukin (IL)-8 promoter. After intratracheal instillation with 150 µM Marimastat and Ilomastat, lung inflammation was monitored by in-vivo bioluminescence imaging and bacterial load in the lungs was assessed. In vitro, the effects of protease inhibitors on PAO1 growth and viability were evaluated. Acute lung infection was established in both wild-type and CFTR knock-out mice. After 24 h, the infection induced IL-8-dependent bioluminescence emission, indicating lung inflammation. In infected mice with ongoing inflammation, intratracheal treatment with 150 µM Marimastat and Ilomastat reduced the bioluminescence signal in comparison to untreated, infected animals. Bacterial load in the lungs was not affected by the treatment, and in vitro the same dose of Marimastat and Ilomastat did not affect PAO1 growth and viability, confirming that these molecules have no additional anti-bacterial activity. Our results show that inhibition of protease activity elicits anti-inflammatory effects in cystic fibrosis (CF) mice with acute P. aeruginosa lung infection. Thus, Marimastat and Ilomastat represent candidate molecules for the treatment of CF patients, encouraging further studies on protease inhibitors and their application in inflammatory diseases.

Abstract
Chest wall tumours are heterogeneous neoplasms, either primary or metastatic, with a malignancy rate of 50%. Surgical resection is one of the mainstays of the treatment, however, chest wall resections can be particularly challenging depending onto the resection size, site and patient habitus. The surgical strategy should be carefully analysed preoperatively, keeping in mind the need of an oncological radical resection (R0) in accordance to the reconstruction principles elicited by le Roux and Sherma since 1983, which include restoring the chest wall rigidity, preserving pulmonary mechanics, protect the intrathoracic organs, avoiding paradox movements of the chest cavity and, possibly, to reduce the thoracic deformity. In this context, we herewith report our surgical reconstruction technique following an anterior chest wall resection and sternal body wedge for a primary chest wall tumour (chondrosarcoma).

Abstract
Chronic diaphragmatic hernia (CDH) is an uncommon disease which may be associated with significant morbidity and mortality. Antecedent (even many months or years before CDH development) blunt or penetrating thoracic/thoraco-abdominal trauma is generally recognized. A wide spectrum of different mechanisms of injury, timing in presentation, size of the diaphragmatic defect, types and amount of abdominal viscera herniated into the chest cavity, clinical symptoms are observed in CDHs. Thoracic and abdominal CT scan (with coronal, axial and sagittal reconstructions) is the best diagnostic tool; sometimes thoracic MRI is needed to better define the extent of the diaphragmatic defect and the number of abdominal organs displaced into the chest cavity. Surgery (sometimes urgent) represents the treatment of choice for CDH; diaphragmatic hernia direct repair with a tension-free suture is generally attempted; in case of very large defects or when a tension-free suture is deemed unfeasible, the use of prosthesis is recommended. This review article will discuss about CDH aetiology, clinical presentation diagnosis and surgical treatment.

Abstract
Post pneumonectomy bronchopleural fistula (BPF) is a life-threatening complication requiring pleural cavity drainage to avoid acute mediastinal shift and contralateral aspiration pneumonia. Chest drain insertion in this situation may be technically difficult because of drastic anatomical changes such as mediastinal dislocation, diaphragm elevation and, sometimes, massive subcutaneous emphysema. In addition, the most important part of the pleural cavity to be drained is the costophrenic recess that is scarcely drained by a standard chest tube with its tip aiming high and upwards. We propose a safe, simple and effective technique based on the siphon principle to drain the lowest part of the pleural cavity.

Abstract
OBJECTIVE To compare the incidence of major adverse cardiac events (MACE) and mortality following video-assisted thoracoscopic surgery (VATS) lobectomy in patients with and without coronary artery disease (CAD). METHODS Multicentre retrospective analysis of 1699 patients undergoing VATS lobectomy (January 2012-March 2015). CAD definition: previous acute myocardial infarct (AMI), angina, percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG). MACE definition: postoperative acute myocardial ischemia, cardiac arrest or any cardiac death. Propensity score analysis was performed to match patients with and without CAD. Outcomes of the 2 matched groups were compared. RESULTS The incidence of MACE and mortality for the entire population was 0.4% (7 patients) and 1.7% (29 patients); 218 patients (13%) had a history of CAD: 106 previous AMI, 55 angina, 32 CABG, and 81 PCI. The propensity score yielded 2 well-balanced groups of 218 pairs with and without CAD. MACE (CAD 2 [0.9%] vs no-CAD 1 [0.5%]; P = 1), cardiovascular and pulmonary complications (CAD 61 [28%] vs no-CAD 51 [23%]; P = .3) and postoperative stay (CAD 7.3 days vs no-CAD 6.2 days; P = .3) were not different between the groups. The incidence of atrial fibrillation (CAD 31 [14%] vs no-CAD 18 [8.2%]; P = .07), 30-day mortality (CAD: 11 [5%] vs no-CAD 2 [0.9%]; P = .02) and death among complicated patients (CAD 18% vs no-CAD 3.9%; P = .009) were higher in the CAD group. CONCLUSIONS The incidence of MACE following VATS lobectomy in patients with CAD is low and similar to patients without CAD. However, their risk of postoperative mortality is fivefold higher compared with non-CAD patients, warranting refined preoperative functional evaluation and more intense postoperative monitoring.

Abstract
Immediately after lung resection, air tends to collect in the retrosternal part of the chest wall (in supine position), and fluids in its lower part (costodiaphragmatic sinus). Several general thoracic surgery textbooks currently recommend the placement of 2 chest tubes after major pulmonary resections, one anteriorly, to remove air, and another into the posterior and basilar region, to drain fluids. Recently, several authors advocated the placement of a single chest tube. In terms of air and fluid drainage, this technique demonstrated to be as effective as the conventional one after wedge resection or uncomplicated lobectomy.

Abstract
Chest wall (CW) involvement occurs in approximately 5% of all primary lung neoplasms. According to the most recent TNM classification, lung tumors invading CW are classified as T3, and they represent approximately 45% of all T3 lung cancers. The most common clinical symptom at presentation is chest pain (>60%), which is highly specific of CW infiltration (>90%). Dyspnoea and hemoptysis are also described, especially in case of large lesions. A realistic chance to cure locally advanced tumors invading CW is a surgical resection, consisting in the excision of the primary lung cancer along with the involved CW (sometimes an "en-bloc" resection) and an appropriate lymph-nodal dissection. However, such patients are at high-risk of facing postoperative complications; prognosis mainly depends on: (I) the completeness of resection; and (II) the lymph-nodal involvement. Hence, due to these reasons (incidence, symptoms, prognosis, post-operative complications), such category of patients are to be carefully assessed preoperatively and if deemed practicable, surgery should be taken into consideration. In this view, the aim of this paper is to critically review the most recent series of lung tumors invading the CW, with a particular focus on patients' preoperative evaluation, surgical techniques, postoperative complications and overall outcome.

Abstract
BACKGROUND To assess the trend of our surgical patients affected by malignant pleural mesothelioma (MPM) and submitted to diagnostic/palliative or curative surgical procedures and to validate the European Organisation for Research and Treatment of Cancer (EORTC) prognostic score in our patient population. METHODS This is a cohort study of patients submitted to surgery for MPM from January 2007 to December 2013. Primary outcome was overall survival (OS). Univariate and multivariate-adjusted comparisons by EORTC prognostic score for OS were accomplished using Cox method. Adjusted models included the following clinical variables: kind of procedure, smoking habit, asbestos exposure, Charlson's Comorbidity Index (CCI), clinical tumor stage, adjuvant chemotherapy, dyspnoea, chest pain and haematological variables according to the score features. Nomenclature of the surgical procedures matches the International Association for the Study Lung Cancer (IASLC)/International Mesothelioma Interest Group (iMIG). RESULTS One-hundred sixty-six consecutive cases were collected: the median age at surgery was 73 years and 123 patients (75%) had a history of asbestos exposure. Ninty patients (54%) were submitted to a palliative/diagnostic thoracoscopy, 30 to pleurectomy/decortication (P/D), and 6 to extra-pleural pneumonectomy (EPP). Clinical TNM stages were as follows: 99 (60%) stage I-II, 34 (20%) stage III and 33 (20%) stage IV. The median follow-up (FU) was 19 months [interquartile range (IQR), 9-31 months] and the FU-completeness was 98%. By the end of the study 130 patients died (78%). One- and 3-year OS was 60% and 36%, respectively. Patients submitted to EPP and P/D showed a better survival (P=0.013). Multivariable model showed an independent prognostic value of EORTC score (HR =2.86, P<0.001). CONCLUSIONS In selected patients, aggressive surgical approaches, although not radical, may still be beneficial. The EORTC prognostic index proved to be an independent prognostic factor in our cohort of patients and therefore is a reliable and valid instrument that may be implemented in the daily practice.

Abstract
Tube thoracostomy is usually the first step to treat several thoracic/pleural conditions such as pneumothorax, pleural effusions, haemothorax, haemo-pneumothorax and empyema. Today, a wide range of drains is available, ranging from small to large bore ones. Indications for an appropriate selection remains yet matter of debate, especially regarding the use of small bore catheters. Through this paper, we aimed to retrace the improvements of drains through the years and to review the current clinical indications for chest drain placement in pleural/thoracic diseases, comparing the effectiveness of small-bore drains vs. large-bore ones.

Abstract
Diclofenac is a non-steroidal antinflammatory drug (NSAID) that finds indication in the treatment of debilitating pathologies characterized by chronic pain sustained by inflammation, such as in rheumatic disease (rheumatoid arthritis or osteoarthritis) or periarthritis, bursitis, tendonitis, myositis and sciatica. Its properties differentiate it from other NSAIDs. In fact, diclofenac's increased effect on spinal nociception and chronic neuro-inflammatory pain may be referred to: 1) its synergistic effects on peroxisome proliferator-activated receptor-γ (PPAR- γ) activation and prostaglandin synthesis inhibition (COX-2 inhibition); 2) its capacity of suppressing neuronal hyperexcitability through the blockage of neuronal K+ channels in a concentration-dependant manner; and 3) its facility to cross the blood-brain barrier.

Abstract
Due to its intrinsic characteristics, video assisted thoracic surgery (VATS) lobectomy is currently the recommended surgical approach for early stage lung cancer treatment. The importance of increasing the number of surgeons capable of performing VATS lobectomies is implicit and of utmost importance. In fact, the need of performing independently and routinely VATS lobectomies for early stage lung cancer will soon be a prerequisite to the new generation of thoracic surgeons. The feeling that VATS lobectomy teaching should be part of their training is strongly felt among trainees but, at the moment, a formal, uniform and certified process of learning VATS lobectomy is not available in all training centres. Perhaps, through the supervision, support and aid from national and European Thoracic Surgery Societies, programs of integration of recognized, standardized and certified teaching of VATS lobectomy could be planned and undertaken by the training centres, both at national as well as European level.

Abstract
Diffuse bleeding after chest wall and spine resection represents a major problem in General Thoracic Surgery. Several fibrin sealants (FS) have been developed over the years and their use has been gradually increasing over time, becoming an important aid to the surgeons, justifying their use across numerous fields of surgery due to its valid haemostatic properties. Among the several FS available, TachoSil(®) (Takeda Austria GmbH, Linz, Austria) stands out for its haemostatic and aerostatic properties, the latter being demonstrated even in high-risk patients after pulmonary resections for primary lung cancers. Several papers available in literature demonstrated TachoSil(®)'s effectiveness in controlling intraoperative and postoperative bleeding in different surgical branches, including hepatic and pancreatic surgery, as well as cardiac and thoracic surgery. However, the use of TachoSil(®) to control diffuse bleeding following major resections for advanced lung cancers, with requirement of chest wall and vertebral body resection for oncological radicality, was never published so far. In this paper, we report three cases of pulmonary lobectomy associated to chest wall resection and haemivertebrectomy for primary malignant lung neoplasms and for a recurrence of malignant solitary fibrous tumour of the pleura in which we used TachoSil(©), which demonstrated its efficacy in controlling diffuse bleeding following resection.

Abstract
BACKGROUND The thoracic morbidity and mortality (TM&M) classification system univocally encodes the postoperative adverse events by their management complexity. This study aims to compare the distribution of the severity of complications according to the TM&M system versus the distribution according to the classification proposed by European Society of Thoracic Surgeons (ESTS) Database in a population of patients submitted to video assisted thoracoscopic surgery (VATS) lung resection. METHODS A total of 227 consecutive patients submitted to VATS lobectomy for lung cancer were analyzed. Any complication developed postoperatively was graded from I to V according to the TM&M system, reflecting the increasing severity of its management. We verified the distribution of the different grades of complications and analyzed their frequency among those defined as "major cardiopulmonary complications" by the ESTS Database. RESULTS Following the ESTS definitions, 20 were the major cardiopulmonary complications [atrial fibrillation (AF): 10, 50%; adult respiratory distress syndrome (ARDS): 1, 5%; pulmonary embolism: 2, 10%; mechanical ventilation >24 h: 1, 5%; pneumonia: 3, 15%; myocardial infarct: 1, 5%; atelectasis requiring bronchoscopy: 2, 10%] of which 9 (45%) were reclassified as minor complications (grade II) by the TM&M classification system. According to the TM&M system, 10/34 (29.4%) of all complications were considered minor (grade I or II) while 21/34 (71.4%) as major (IIIa: 8, 23.5%; IIIb: 4, 11.7%; IVa: 8, 23.5%; IVb: 1, 2.9%; V: 3, 8.8%). Other 14 surgical complications occurred and were classified as major complications according to the TM&M system. CONCLUSIONS The distribution of postoperative complications differs between the two classification systems. The TM&M grading system questions the traditional classification of major complications following VATS lung resection and may be used as an additional endpoint for outcome analyses.

Abstract
OBJECTIVES To assess the postoperative incidence of major complications in high-risk patients following video-assisted thoracoscopic surgery (VATS) lobectomy for lung cancer compared with their lower risk counterparts. METHODS A retrospective analysis on prospectively collected data of 348 consecutive patients subjected to VATS lobectomy (August 2012-September 2014) was performed. Patients were defined as high risk if one or more of the following characteristics were present: age >75 years, forced expiratory volume in 1 s (FEV1) <50%, carbon monoxide lung diffusion capacity (DLCO) <50%, history of coronary artery disease (CAD). Severity of complications was graded using the Thoracic Morbidity and Mortality (TM&M) score; major complications were defined if the TM&M score was greater than 2. The propensity score was used to match high-risk patients with their lower risk counterparts in order to minimize the influence of other confounders on outcome. The following variables were used to construct the propensity score: gender, side of operation, body mass index, American Society of Anaesthesiologists score, Eastern Cooperative Oncology Group score, Charlson's Comorbidity Index, number of functioning segments resected. RESULTS The high-risk group consisted of 141 patients (age >75 years: 84 patients; FEV1 <50: 14 patients; DLCO <50: 25 patients; history of CAD: 37 patients). The propensity score yielded two groups of 135 patients (high-risk vs low-risk) well matched for several baseline characteristics except for a lower performance status in the higher-risk group. Compared with their low-risk counterparts, high-risk patients had a higher incidence of cardiopulmonary complications (28 cases, 21% vs 14 cases, 10%; P < 0.0001) and major cardiopulmonary complications (12 cases, 9% vs 3 cases, 2%; P < 0.0001). Postoperative stay was 3 days longer in high-risk patients (8.6 vs 5.5 days, P = 0.0031). The 30-day or in-hospital mortality rates were not different between the two groups (2 cases, 1.5% vs 3 cases, 2.2%, P = 0.93). CONCLUSIONS The incidence of major complications after VATS lobectomy in high-risk patients is low, but not negligible. This information can be used when discussing surgical risk with the patient during preoperative counselling.

Abstract
The non-steroidal anti-inflammatory drugs (NSAIDs) are among the most widely used drugs in the control of postoperative pain. In choosing the NSAID to be used, it is essential to assess the most favorable risk/benefit ratio according to a careful assessment of intrinsic and extrinsic risk factors and cardiovascular, gastrointestinal, renal and metabolic patient comorbidities. Diclofenac dose of 150 mg/die is the NSAID that has wider literature that attests its efficacy and tolerability. Due to its high lipid solubility, it is one of the few NSAIDs that are able to cross the blood-brain barrier, with an action principally directed towards COX-2. Over time, several studies have been conducted to evaluate the side effects of NSAIDs. Regarding Diclofenac's cardiovascular and gastrointestinal tolerability, recent studies indicate that the relative risk and absolute risk of complications of Diclofenac are similar to COXIB and inferior to other NSAIDs. Important feature of Diclofenac is that, unlike other NSAIDs, it does not interfere with the cardio-protective effect of acetyl-salicylic acid. Diclofenac potassium is instead indicated for use as an analgesic in headache and as an antipyretic in influenza-like symptoms. Studies with the aim of investigating the intestinal damage exacerbated by proton pump inhibitors drugs, when associated with NSAIDs, state that at least in part, they aggravate the intestinal damage induced by NSAIDs due to significant changes in intestinal microbial populations. The reference dose of Diclofenac used in all randomized controlled trials is 150 mg/die; this controlled release dosage allows to decrease the number of daily administrations, ensuring a better patient compliance, especially if elderly and/or in polytherapy.
