RESUMO
Background: Solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm, generally arising in the visceral pleura. It rarely originates from other sites such as trachea, orbital cavities, nasal cavities, peritoneum, paranasal sinuses, meninges, salivary glands, thyroid gland, diaphragm, liver, pancreas, lung kidney, adrenal gland, mediastinum, spermatid cord, pericardium, urinary bladder, prostate, uterine cervix, testis, spinal cord, periosteum, skin, soft tissue and bone. Case Description: We present a surgical case of a rare primary tracheal tumor. High resolution computed tomography (HRCT) scan of the chest showed a 5 mm hypodense lesion, located on the right lateral wall of the proximal third of trachea; however the tracheal lumen was normal. We performed a rigid bronchoscopy in order to remove the endotracheal tumor with palliative purposes only. For this reason, we did not perform a prior histologic examination. The lesion was easily removed with common biopsy forceps and with standard aspirator. The debulking of the tumor was achieved with the use of laser Nd-YAP, electrocautery was used also for hemostasis to prevent bleeding during the operation. Without complications during the endoscopic treatment, the procedure was well tolerated by the patient. The pathological diagnosis was SFT. Conclusions: SFT located in the trachea can be endoscopically resceted. Endoscolical treatment is indicated for patients with poor clinical conditions (heart disease, respiratory failure) that are not elegible for surgical resection.
RESUMO
BACKGROUND: Malignant pleural mesothelioma (MPM) is an invasive, aggressive pleural tumor with a predominantly local spread. The objective of this study was to assess thoracic ultrasound (TUS) as an imaging modality with high sensitivity for the identification of malignant pleural involvement and in order to guide pleural biopsies. METHODS: In this retrospective single-center study between January 2018 and June 2022, 51 consecutive patients with impassable circumferential pleural thickening underwent TUS at the Thoracic Surgery Unit of the Vanvitelli University of Naples. Pleural biopsies were performed, and then large and multiple samples were sent to the pathological anatomy for histological examination. RESULTS: In all patients who underwent ultrasound examination, we chose the optimal point of entry to perform pleural biopsies and selected the areas of greater thickening without pleural effusion. No patient had any complications. No drainage tubes were placed after the pleural biopsies and no pneumothorax was present during the following days of hospitalization. The patients were discharged on the second postoperative day. CONCLUSION: With TUS the precise pleural thickening localization, local infiltration, mass extent, its nature (solid, cystic or complex) and ultrasound features can be easily defined. Furthermore, ultrasound is more economical than computed tomography and avoids the risks associated with radiation. Thoracic ultrasound is an important component of the diagnostic procedure in detecting a safe entry site for biopsies of MPMs.

BACKGROUND: Incomplete interlobar fissure may increase the difficulty of thoracoscopic lobectomy. Herein, we compared the accuracy of visual versus quantitative analysis to predict fissure integrity in lung cancer patients undergoing thoracoscopic lobectomy and evaluated the effects of fissure integrity on surgical outcome. METHODS: This was a single-center retrospective study including consecutive patients undergoing VATS (video-assisted thoracoscopic surgery) lobectomy for lung cancer. The target interlobar fissures were classified as complete or incomplete by visual and quantitative analysis. Using the intraoperative finding as the reference method, the diagnostic accuracy of the two methods to define fissure completeness (dependent variable) was calculated and statistically compared. Yet, we evaluated differences in postoperative outcomes between patients with complete and incomplete fissure integrity. RESULTS: A total of 93 patients were included in the study; 33/93 (36%) presented complete fissure. Visual and quantitative analyses correctly identified complete fissure in 19/33 (57%) and 29/33 (88%) patients, respectively, and incomplete fissure in 56/60 (93%) and 58/60 (96%) patients, respectively. Quantitative analysis had better diagnostic accuracy than visual analysis (81 vs. 93%; p = 0.01). Patients with incomplete fissure compared with those with complete fissure had a higher conversion rate (6 vs. 13%; p = 0.43), higher persistent air leak rate (0/33 vs. 14/60; p = 0.03), and longer hospitalization (12.6 ± 3.8 vs. 7.1 ± 2.4 days; p = 0.01). CONCLUSION: Quantitative analysis accurately predicted the fissures' integrity; it may be useful for selecting suitable cases for thoracoscopic lobectomy especially for surgeons with limited minimally invasive experience.

INTRODUCTION: Central airway tumors involving the trachea and main-stem bronchi are a common cause of airway obstruction and a significant cause of mortality among the patients of thoracic diseases with respiratory failure. Debulking in rigid bronchoscopy is quick, safe, and effective. It can be complex and hard in patients with severe bronchial or tracheal obstruction and/or with intraluminal bleeding tumors because of inadequate distal airway control. We have used laser tube as a new technique of ventilation for severe central airway obstruction. MATERIALS AND METHODS: Forty-six patients with severe airway obstruction undergoing rigid bronchoscopy from September 2020 to June 2022 at the Thoracic Surgery Department of the University L. Vanvitelli of Naples underwent placement of laser tube. RESULTS: In all patients who underwent rigid bronchoscopy with the use of the laser tube, a reduction of obstruction of more than 50% was obtained and in all patients no hypoxia (saturation < 88%), nor hypercapnia, nor significant bleeding were reported. DISCUSSION: The results of this study suggest that rigid bronchoscopic debulking with the use of laser tube is a safe and effective technique in the management of central airway obstruction. CONCLUSIONS: The use of the laser tube allows the monitoring of gas exchange, which controls hypoxemia. Thanks to the double cuff put distally to the tracheal obstruction or in the contralateral bronchus to the obstructed one, the laser tube prevents the flooding of blood from debulking below the stenosis. Rigid bronchoscopy with laser tube will expand its use in the future.

PURPOSE: Surgical treatment of primary lung T4 tumors is controversial especially when the cancer invades the mediastinal structures or the descending thoracic aorta. Conventional surgical treatment is associated with a high perioperative mortality and morbidity rate. Thoracic EndoVascular Aortic Repair has emerged as a valid off-label alternative to conventional surgery. We aimed to assess perioperative and midterm aortic-related outcome of patients who have undergone aortic stent-graft implantation, followed by en bloc surgical treatment of the involved aorta and lung cancer resection. MATERIALS AND METHODS: From July 2017 to May 2020, we treated 5 patients diagnosed with a T4 lung cancer by the involvement of the descending thoracic aorta. When only the descending thoracic aorta is involved, a 2-stage procedure was considered, with aortic stent-graft implantation performed before tumor resection. One-stage strategy, with stent-graft implantation carried out before thoracotomy, was preferred for patients with the involvement of cardiac and/or other vascular mediastinal structures. RESULTS: The mean age was 58.4 ± 6.2 years. All patients were affected by non-small cell lung cancer. All 5 patients required a single stent-graft to completely cover the involved segment of aorta. Four patients underwent a 2-stage procedure. One patient, with the involvement of the left inferior pulmonary vein, required a 1-stage en bloc resection of the left lower lobe, aortic wall adventitia, left inferior pulmonary vein, and reconstruction of the left atrial wall. Primary procedural success was achieved in all. At follow-up, no patient developed aortic-related complications. One patient died 2 years after surgery, due to local recurrence of the tumor. CONCLUSION: T4 lung resection combined with aortic stent-graft implantation can be safely performed. Endovascular surgery, by avoiding the use of cardiopulmonary bypass, aortic cross-clamping, and graft replacement, can reduce significant morbidity and mortality rate. Postoperative and long-term outcome of these patients treated with endovascular surgery is mainly related to pulmonary disease, not to aortic treatment.

BACKGROUND: The management of intraoperative bleeding during thoracoscopic lobectomy is challenging, especially for non-experienced surgeons. We evaluated intraoperative bleeding in relation to learning curve of thoracoscopic lobectomy, the strategies to face it, the outcomes, and the target case number for gaining the technical proficiency. METHODS: This was a retrospective single center study including consecutive patients undergoing thoracoscopic lobectomy for lung cancer. Based on cumulative sum analysis, patients were divided into early and late experience groups, and the differences on surgical outcomes, with particular focus on vascular injury, were statistically compared. RESULTS: Eight-three patients were evaluated. Cumulative sum charts showed a decreasing of operative time, blood loss, and hospital stay after the 49th, the 43th, and the 39th case, respectively. Early (n = 49) compared with late experience group (n = 34) was associated with higher conversion rate (p = 0.08), longer operative time (p <0.0001), greater blood loss (p <0.0001), higher transfusion rate (p = 0.01), higher postoperative air leak rate (p = 0.02), longer chest tube stay (p <0.0001), and hospitalization (p <0.0001). Six patients (7%) had intraoperative bleeding during early phase of learning curve, successfully treated by thoracoscopy in four cases. Patients with vascular injury (n = 6) compared with control group (n = 77) presented a longer operative time (p = 0.003), greater blood loss (p = 0.0001), and higher transfusion rate (p = 0.001); no significant differences were found regarding postoperative morbidity (p = 0.57), length of chest tube stay (p = 0.07), and hospitalization (p = 0.07). CONCLUSION: Technical proficiency was achieved after 50 procedures. All vascular injuries occurred in the early phase of learning curve; they were safely managed, without affecting surgical outcomes.

Malignant pleural mesothelioma (MPM) is a highly lethal malignancy that unfortunately cannot benefit from molecularly targeted therapies. Although previous results showed the pivotal role of various receptor tyrosine kinases (RTKs) in MPM tumorigenesis, the treatment with a single inhibitor targeting one specific RTK has been shown to be ineffective in MPM patients. The main aim of the present study was to investigate the potential role of AXL and MET receptors in MPM and the possible efficacy of treatment with AXL and MET multitarget inhibitors. Immunohistochemical and FISH analyses were performed in a wide series of formalin-fixed paraffin-embedded MPM samples to detect the expression of two receptors and the potential gene amplification. In vitro studies were performed to evaluate putative correlations between the target's expression and the cell sensitivity to AXL-MET multitarget inhibitors. In our series, 10.4% of cases showed a co-expression of AXL and MET, regardless of their ligand expression, and the gene amplification. Furthermore, our in vitro results suggest that the concomitant pharmacological inhibition of AXL and MET may affect the proliferative and aggressiveness of MPM cells. In conclusion, the subset of MPM patients with AXL-MET co-activation could benefit from treatment with specific multitarget inhibitors.
RESUMO
Preexisting para-esophageal hernia may increase the risk of postoperative complications after lobectomy for lung cancer. A combined laparoscopic hernia repair and thoracoscopic lobectomy may be performed to manage hernia and lung cancer concurrently. This approach possibly prevented complications from the presence of hernia after lobectomy.

INTRODUCTION: Staging of the mediastinum lymph nodes involvement in patients with non-small cell lung cancer (NSCLC) is an important prognostic factor determining the most appropriate multimodality treatment plan. The objective of this study is to assess ultrasound characteristics of mediastinal lymph nodes metastasis and effectiveness of intraoperative ultrasound-guided mediastinal nodal dissection in patients with resected NSCLC. MATERIALS AND METHODS: All patients undergoing video-assisted thoracoscopic surgery lobectomy and pulmonary lymphadenectomy from November 2020 to March 2022 at the thoracic surgery department of the Vanvitelli University of Naples underwent intraoperative ultrasound-guided mediastinal lymph nodal dissection. RESULTS: This study evaluates whether individual B-mode features and a compounding thereof can be used to accurately and reproducibly predict lymph node malignancy. DISCUSSION: Intraoperative ultrasound, during systematic mediastinal lymph node dissection, is helpful in preventing lesion to mediastinal structures. Pathological nodal sonographic characteristics are round shape, short-axis diameter, echogenicity, margin, the absence or presence of coagulation necrosis sign, and the absence or presence of central hilar structure, increased color Doppler flow, the absence or presence of calcification, and nodal conglomeration. Operating time was not substantially prolonged. The procedure is simple, safe and highly accurate. CONCLUSIONS: Ultrasonic techniques allow surgeons to detect the relationship between lymph nodes and surrounding large blood vessels during biopsy, improving the safety and simplicity of the operation, increasing the number of harvested lymph nodes, and reducing the risk of intraoperative injury; it is a fast, easily reproducible, and inexpensive method.

INTRODUCTION: Many clinical studies have shown ultrasonography (US) is useful for the diagnosis of different abnormalities involving pleura; chest ultrasound (CUS) is widely used to detect pneumothorax in patients, but there is no data on its use for the follow-up of lung re-expansion after lung resection. MATERIALS AND METHODS: We performed a unicentric observational study all patients between January 2018 and May 2021 undergoing lobectomy in which lung re-expansion was assessed daily with chest ultrasound (CUS) and chest radiography (CXR) until chest drainage was removed. Ultarsound clinical signs indicating a pneumothorax were: the detection of a positive lung point, absence of sliding or a consistent stratosphere sign with an absence of lung pulse, B-lines, I-lines or consolidations. RESULTS: Sensitivity, specificity, PPV, NPV of CUS and CXR were, respectively: 86% vs. 98% (p = 0.002); 100% vs. 100% (p = 1.0); 94% vs. 75% (p = 0.231); and 94% vs. 99% (p = 0.7). CONCLUSIONS: Ultrasound is a method available also to the patient's bed, an easy-to-learn technique even for inexperienced operators, therefore it is a valuable tool for checking the post-lobectomy lung expansion, reduce the use of chest radiography. KEY WORDS: Chest ultrasound, Chest radiography, Pneumothorax.

OBJECTIVES: Application of video-assisted thoracoscopy brought lung surgery into the minimally invasive era; the lack of tactile feedback using VATS, remains a disadvantage because surgeons are unable to locate lesions with a finger or device. This study aimed to investigate the effectiveness, the applicability and the utility of intraoperative ultrasound (IU), for the localization of small ground-glass opacity (GGO) lesions in the parenchyma, as a guide in finding their margins in a deflated lung. MATERIALS AND METHODS: We included 15 consecutive patients undergoing diagnostic resection of GGOs via VATS in the Thoracic Surgery Unit of the University of 'Luigi Vanvitelli' of Naples from November 2019 to December 2021. They were under general anaesthesia, when the lung had been collapsed, the probe was placed in the region where the target lesion was thought to reside on the basis of low-dose computed tomography scanning. GGO could be identified their sizes, echo levels and posterior echo was recorded by IU when the lung was completely deflated. RESULTS: We conducted a retrospective single-centre study. All GGOs were identified by IU. The mean size and depth were 14.1 ± 0.5 and 4.8 ± 0.3 mm, respectively. Six (40%) lesions had hyperechoic patterns, 9 (60%) had mixed echogenicity where the hyperechoic patterns were irregularly mixed with hypoechoic patterns. The final diagnoses included 2 (15%) atypical adenomatous hyperplasia; 2 (15%) adenocarcinomas in situ; 3 (23%) minimally invasive adenocarcinomas and 6 (46%) invasive adenocarcinomas. CONCLUSIONS: The results of our study showed that IU could safely and effectively detect GGOs.

Congenital pericardial defect is an uncommon anomaly due to the congenital absence of the pericardium. In this case, it was associated with diaphragmatic hernia and incidentally discovered during thoracoscopic left upper lobectomy for lung cancer. The thoracoscopic dissection of the hilar structures was complicated with arrhythmia and hypotension. Thus, we converted thoracoscopy to thoracotomy, and the lobectomy was successfully performed. The pericardial defect and diaphragmatic hernia were not repaired, but the vessels and bronchial stump were covered to avoid heart injury. Postoperative course was unremarkable and at six-month follow-up patient did not have any problems.

The potential complications related to unplanned conversion to thoracotomy remains a major concern in thoracoscopic lobectomy and may limit the wide adoption of this strategy. We reviewed the literature from 1990 until February 2022, analyzing all papers comparing successful thoracoscopic lobectomy versus converted thoracoscopic lobectomy and/or upfront thoracotomy lobectomy to establish whether unplanned conversion negatively affected outcomes. Thirteen studies provided the most applicable evidence to evaluate this issue. Conversion to thoracotomy was reported to occur in up to 23% of cases (range, 5%-16%). Vascular injury, calcified lymph nodes, and dense adhesions were the most common reasons for conversion. Converted thoracoscopic lobectomy compared to successful thoracoscopic lobectomy was associated with longer operative time and hospital stay in all studies, with higher postoperative complication rates in seven studies, and with higher perioperative mortality rates in four studies. No significant differences were found between converted thoracoscopic lobectomy and upfront thoracotomy lobectomy. Five studies evaluated long-term survival, and in all papers conversion did not prejudice survival. Surgeons should not fear unplanned conversion during thoracoscopic lobectomy, but to avoid unexpected conversion that may negatively impact surgical outcome, a careful selection of patients is recommended-especially for frail patients.

Lung cancer is the most lethal cancer: it has a significant incidence and low survival rates. Lifestyle has an important influence on cancer onset and its progression, indeed environmental factors and smoke are involved in cancer establishment, and in lung cancer. Physical activity is a determinant in inhibiting or slowing lung cancer. Certainly, the inflammation is a major factor responsible for lung cancer establishment. In this scenario, regular physical activity can induce anti-inflammatory effects, reducing ROS production and stimulating immune cell system activity. On lung function, physical activity improves lung muscle strength, FEV1 and forced vital capacity. In lung cancer patients, it reduces dyspnea, fatigue and pain. Data in the literature has shown the effects of physical activity both in in vivo and in vitro studies, reporting that its anti-inflammatory action is determinant in the onset of human diseases such as lung cancer. It has a beneficial effect not only in the prevention of lung cancer, but also on treatment and prognosis. For these reasons, it is retained as an adjuvant in lung cancer treatment both for the administration and prognosis of this type of cancer. The purpose of this review is to analyze the role of physical activity in lung cancer and to recommend regular physical activity and lifestyle changes to prevent or treat this pathology.
RESUMO
INTRODUCTION: Video-assisted thoracic surgery (VATS) for ipsilateral reoperations is controversial, because after the first surgical intervention, pleural adhesions occur frequently in the thoracic cavity and/or chest wall. This study assessed the usefulness of preoperative ultrasonography to reduce the incidence of lung injury at the time of the initial port insertion during secondary ipsilateral VATS. MATERIALS AND METHODS: This was a retrospective, single-center study. Nine patients who underwent thoracic surgery at Vanvitelli Hospitalfrom September 2019 to February 2022, were scheduled for a second VATS surgeryon ipsilateral lung, because of inconclusive intraoperative histologic examination. All nine patients underwent preoperative ultrasonography to assess the possible presence of pleural adhesions. We evaluated the lung sliding, since the presence of pleural adhesions does not permit to appreciate it. STATISTICAL ANALYSIS: Hard severe adhesions were observed in all nine patients without sliding lung sign (specificity 100%). In this series, the sensitivity, PPV, and NPV of the sliding lung sign were 93%, 100% and 94% respectively. RESULTS: The presence of the lung respiratory changes can be evaluated as the "sliding lung sign" by chest ultrasonography; we believe that the sliding lung sign might also predict intrathoracic adhesion. CONCLUSIONS: Preoperative detection of pleural adhesions using transthoracic ultrasonography was useful for ipsilateral secondary pulmonary resection patients undergoing VATS. Using preoperative ultrasonography can improve the safety and feasibility of placing the initial port in VATS.

Enhanced recovery after surgery protocols have shown improved clinical outcomes after lung resection surgery, but their application after empyema surgery is still limited. We retrospectively evaluated the outcomes of an adapted enhanced recovery after surgery (ERAS) protocol for immunocompromised patients who underwent video-assisted thoracoscopic surgery (VATS) surgery for chronic empyema between December 2013 and December 2021. The patients were divided into an ERAS group and a conventional treatment group. Peri-operative data were collected and compared between the two groups. The primary outcome was post-operative length of stay. Secondary outcomes were post-operative pain and post-operative complications (air leaks, atelectasis). A total of 86 patients, 45 in the ERAS group and 41 in the non-ERAS group, were considered. Chest tube duration (6.4 ± 2.3 vs. 13.6 ± 6.8 days) and post-operative length of stay (7.6 ± 1.6 vs. 16.9 ± 6.9 days) were significantly shorter in the ERAS group. The volume of chest drainage (103 ± 78 vs. 157 ± 89 mL/day) was significantly smaller in the ERAS group. There were no significant differences in operative time, blood loss, need for transfusion, tube reinsertion and median VAS score. The incidence of air leaks and atelectasis was significantly reduced in the ERAS group, as was the need for bronchoscopic aspiration. The application of an ERAS protocol after empyema VATS surgery for immunocompromised patients improved the surgical outcome, reducing the post-operative length of stay and rate of complications.
RESUMO
Prolonged chest tube drainage is one of the most common postoperative complications of pulmonary resections; it is related to complications such as residual pleural spaces or continuous alveolar air leaks. We retrospectively evaluated the efficacy of artificial intraoperative pneumoperitoneum in the treatment of such complications after lung resections. The presence of a residual space associated with prolonged air leaks can be difficult to treat, exposes the patient to a high risk of infection, prolongs hospitalization, and in some cases mandates reoperation. Between October 2016 and March 2020, four patients underwent pneumoperitoneum. The obliteration of the pleural cavity and the absence of air leaks were observed in 3 patients; only 1 patient was discharged with a Heimlich valve. Artificial intraoperative pneumoperitoneum is a safe and simple procedure. It decreases the duration of chest drainage and of the hospital stay; however, further studies are needed to corroborate our data. The learning curve for this technique may be relatively short.

Lung cancer is a devastating disease with a high incidence and low survival rates, so recent studies have focused on analyzing the risk factors that might prevent this disease from developing or have protective/therapeutic effects. Nutrition is an important key factor in the prevention and treatment of lung cancer. Various factors appear to be involved in the development of the latter, such as cigarette smoking or certain external environmental factors. The increase in oxidative stress is therefore an integral part of the carcinogenesis process. The biological role of bioactive factors derived from adipose tissue, mainly adipokines, is implicated in various cancers, and an increasing body of evidence has shown that certain adipocytokines contribute to the development, progression and prognosis of lung cancer. Not all adipokines stimulate tumor growth; in fact, adiponectin inhibits carcinogenesis by regulating both cell growth and the levels of inflammatory cytokines. Adiponectin expression is deregulated in several cancer types. Many nutritional factors have been shown to increase adiponectin levels and therefore could be used as a new therapeutic strategy for combating lung cancer. In addition, foods with antioxidant and anti-inflammatory properties play a key role in the prevention of many human diseases, including lung cancer. The purpose of this review is to analyze the role of diet in lung cancer in order to recommend dietary habit and lifestyle changes to prevent or treat this pathology.
