Background: In the setting of solitary pulmonary nodules (SPNs), fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography ( 18 F-FDG-PET/CT) is considered a useful noninvasive diagnostic tool though false positive (FP) and false negative (FN) results affects accuracy due to different conditions, such as inflammatory diseases or low-uptake neoplasms. Aim of this study is to evaluate overall diagnostic performance of 18 F-FDG-PET/CT for malignant pulmonary nodules. Methods: A computerized research, including published articles from 2012 and 2017, was carried out. 18 F-FDG-PET/CT overall sensitivity (Se), specificity (Spe), positive likelihood ratio (PLR), negative likelihood ratio (NLR), positive predictive value (PPV), negative predictive value (NPV), diagnostic index and odds ratio were pooled. No selection-bias were found according to asymmetry test. Results: A total of twelve studies were included in the meta-analysis. The pooled Se, Spe, PLR, NLR, PPV, NPV and accuracy index (AI) with relative 95% confidence intervals (CI) were 0.819 (95% CI: 0.794– 0.843), 0.624 (95% CI: 0.582–0.665), 2.190 (95% CI: 1.950–2.440), 0.290 (95% CI: 0.250–0.330), 0.802 (95% CI: 0.783–0.819), 0.652 (95% CI: 0.618–0.684) and 0.649 (95% CI: 0.625–0.673), respectively. The diagnostic odds ratio (DOR) was 7.049 with a relative 95% CI between 5.550 and 8.944. Conclusions: The results suggest 18 F-FDG-PET/CT has good diagnostic accuracy in SPNs evaluation; but, it should not be considered as a discriminatory test rather than a method to be included in a clinical and diagnostic pathway.

The national registers arise from the need to collect data in order to improve the known techniques and to direct towards new treatment strategies. In this study we tried to emphasize the importance of the sampling of information taking into account two aspects: (I) analysis of learning curves; (II) the choice of surgical strategies, by which to set a standardization of techniques designed to establish future treatment guidelines. Data collection and medical practice will influence each other. In fact, we find in literature several studies conducted on very large series which provide valuable support to the therapeutic choices. The goal is to reach new standards of treatment, through the consent of the national and international scientific community.

Background: The VATS Group and the National Register for VATS Lobectomy were set up in 2013. Both quality and quantity of collected data within the database are two fundamental tools for scientific and statistical purposes, similar to other important databases, such as the European Society of Thoracic Surgeons (ESTS) Database, the Society of Thoracic Surgeons General Thoracic Surgery Database (STS GTSD) and the Danish Lung Cancer Registry (DLCR). Methods: Four thousand seven hundred and four VATS lobectomy patients have recruited to date. Several parameters were recorded, such as preoperative clinical condition, surgical treatment as far as technical details, postoperative course and follow-up. Results: The Eastern Cooperative Oncology Group (ECOG) performance status was 0.27. Uni-portal approach was used in 332 patients, three-portal approach in 3,825 and bi-portal approach in 547. Lymphadenectomy was performed in 4,704 patients: a sampling nodal dissection in 1,180 patients and a radical nodal dissection in 3,524 cases. Conversion rate was in 9.99% of cases. Adenocarcinoma is the most common histologic type (53.34%), followed by squamous carcinoma (15.53%). Conclusions: The structure of the Italian Registry of VATS Lobectomy makes it a valid source to draw on for statistical studies for scientific purposes.

To evaluate the performance of the Quantiferon®-TB Gold In-Tube (QFT-IT) interferon (IFN)-γ assay for the detection of latent tuberculosis infection (LTBI) in children receiving anti-rheumatic treatment in a tertiary referral hospital of Northern Greece. A total of 79 consecutive children receiving anti-rheumatic treatment [of which 18 screened prior to antitumor necrosis factor (TNF)-α treatment] were tested using Mantoux tuberculin skin test (TST) and QFT-IT. Association of both tests with risk factors for latent tuberculosis and Bacillus Calmette-Guerin immunization was determined. Influence of age, TNF-α inhibitors, systemic corticosteroids, conventional disease modifying anti-rheumatic drugs (DMARDs) and total duration of therapy on the QFT-IT mitogen-induced response was evaluated. Agreement between TST and QFT-IT results was moderate (k=0.38). Frequency of QFT-IT indeterminate results was low (2.5%). In patients with risk factors for LTBI, the odds of a positive IFN-γ assay was increased by a factor of 27.6 (P=0.002), whereas there was no positive TST. There was a significant difference in the mitogen-induced IFN-γ secretion among various treatments (P=0.038). TNF-α inhibitors were associated with increased mitogen-induced IFN-γ secretion compared to monotherapy with conventional DMARDs (P=0.008). All children screened prior to anti-TNF-α treatment exhibited a negative QFT-IT and no active TB disease was detected during a 2-year follow-up. QFT-IT may be a more reliable test than TST for detection of LTBI in children with rheumatic diseases receiving anti-rheumatic treatment. Drug regimen might influence the mitogen-induced IFN-γ secretion and the effect of TNF-α inhibitors might vary according to the specific agent administered.

Video-assisted thoracoscopic surgery (VATS) lobectomy represents, nowadays, the gold standard for the treatment of early-stage non-small cell lung cancer (NSCLC). This approach provides a viable alternative to open lobectomy, in terms of radical oncological surgery and of low incidence of complications, as a consequence of sustained innovations and improvements, due to the new available technology devices. Aim of the study was to evaluate the benefits and feasibility of such minimally invasive approaches throughout a careful review of the literature.

Lung cancer is one of the most frequent neoplastic diseases. To date, most lung cancer is diagnosed at an advanced stage, making it difficult to choose the diagnostic and therapeutic strategy. Surgical resection represents the best therapeutic solution. However, the best results are obtained only in the early stages of the disease. Lymph node involvement conditions the treatment (surgical or non-surgical approach). Mediastinoscopy is an effective and widely used method for mediastinal staging but does not allow us to reach many mediastinal lymph nodes. Endobronchial ultrasound/transbronchial needle aspiration (EBUS-TBNA) allows us to reach more lymph nodes and is referred to as a first-choice exam for mediastinal staging.

In the setting of a stage IV non-small cell lung cancer (NSCLC), oligometastatic patients represent a heterogeneous group whose incidence is increasing as far as with the adoption of new therapeutic regimens, the improvement of the molecular characterization assays and the increasing number of long-survivor patients. The oligometastatic state undergone a major revision with the introduction of the new TNM lung cancer staging system, being characterized by a different prognosis compared to multi-metastatic patients. Furthermore, the presence of a limited number of metastases imposes a local control especially when clonal selections occur during adjuvant therapy. In this regard, the review seeks to clarify the indications for surgical treatment by organ according to recent guidelines, by analyzing prognostic factors and outcome of patients. Although accurate patient stratification is mandatory, aggressive local control strategies represent a valid therapeutic approach in patients with oligometastatic NSCLC. At the same time, persevering with ablative strategies raises both medical and ethical issues about limits and reiteration, which certainly requires a deep reflection, being, on the other hand, in front of a metastatic disease.

Video-assisted thoracoscopic (VAT) procedures are emerging for treatment of both benign and malignant thoracic diseases and substituting classical approaches, such as thoracotomies, thanks to several advantages concerning postoperative morbidity rates and overall patients’ outcome (i.e., postoperative pain, chronic pain and quality of life). However, a VAT approach needs an established learning curve making procedures as safe as in open surgery. With regard of trainee surgeons, notwithstanding an increasing number of learning tools and strategies, such as simulation programs (i.e., black-boxes, wet labs, cadaver or animal labs, 3D virtual reality simulators) and direct observation both of live surgery and videos with a supportive evidence base from benchtop studies, there remains inconsistent adoption in surgical educations.

Pleural empyema represents a frequent disease, characterized sometimes by blurred and unspecific signs or symptoms but requiring timely diagnosis in order to plan the most appropriate therapeutic regimen. Several classifications have proposed and the most widely used is the American Thoracic Society (ATS) one, according to increasing severity depending of the extent of disease. Different therapeutic strategies such as conservative regimens (antibiotic therapy and chest tube placement) and surgical one (empyemectomy with pleural decortication) were applied. To this date, minimally invasive surgery is assuming an important role in the management of empyema and represents the gold standard in stage II disease and a valid alternative to the classical approach in stage III in absence of a complete obliteration of the pleural space. Aim of the work is to define, through a comprehensive review of literature, the role of video-assisted thoracoscopic surgery according to limits and advantages compared to conservative methods and the most invasive surgical approaches.
