Video-assisted thoracic lobectomy for lung cancer in Italy: The 'VATS Group' Project
As part of the third Mediterranean Symposium in Thoracic Surgical Oncology, we introduce
the Italian VATS Group (http://vatsgroup.org/sito/index.php). This national collaborative
initiative was established in 2013 and started to recruit patients in January 2014; as of July
2016, 3680 patients have been enrolled in the database. Three different video-assisted
thoracic surgery approaches have been predominantly used by Italian thoracic surgery
centers, 71% of them preferentially adopting a multi-portal approach, with a 20% recorded
morbidity. The majority of the cases were stage I adenocarcinomas of the lung. Conversion
to open surgery occurred in 9% of the cases. The study suggests video-assisted thoracic
surgery lobectomy as a ‘gold standard’ for the surgical treatment of early-stage lung cancer
in Italy

Conversion due to vascular injury during video-assisted thoracic surgery lobectomy: a multicentre retrospective analysis form the Italian video-assisted thoracic surgery group registry
Vascular injuries in VATS lobectomies represented a rare complication which could directly affect the postoperative outcomes. The predictive factors for conversion were multifactorial and depended on characteristichs of centres and surgeon's seniority. Minimally invasive VATS lobectomy approaches did not influence the risk of vaclular damages
Is It Possible to Establish a Reliable Correlation between Maximum Standardized Uptake Value of 18-Fluorine Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography and Histological Types of Non-Small Cell Lung Cancer? Analysis of the Italian VATS Group Database
Background. Although positron emission tomography/computed tomography, often integrated with 2-deoxy-2-[fluorine-18] fluorine-D-glucose (18F-FDG-PET/CT), is fundamental in the assessment of lung cancer, the relationship between metabolic avidity of different histotypes and maximum standardized uptake value (SUVmax) has not yet been thoroughly investigated. The aim of the study is to establish a reliable correlation between Suvmax and histology in non-small cell lung cancer (NSCLC), in order to facilitate patient management. Methods. We retrospectively assessed the data about lung cancer patients entered in the Italian Registry of VATS Group from January 2014 to October 2019, after establishing the eligibility criteria of the study. In total, 8139 patients undergoing VATS lobectomy were enrolled: 3260 females and 4879 males. The relationship between SUVmax and tumor size was also analyzed. Results. The mean values of SUVmax in the most frequent types of lung cancer were as follows: (a) 4.88 ± 3.82 for preinvasive adenocarcinoma; (b) 5.49 ± 4.10 for minimally invasive adenocarcinoma; (c) 5.87 ± 4.18 for invasive adenocarcinoma; and (d) 8.85 ± 6.70 for squamous cell carcinoma. Processing these data, we displayed a statistically difference (p < 0.000001) of FDG avidity between adenocarcinoma and squamous cell carcinoma. Moreover, by classifying patients into five groups based on tumor diameter and after evaluating the SUVmax value for each group, we noted a statistical correlation (p < 0.000001) between size and FDG uptake, also confirmed by the post hoc analysis. Conclusions. There is a correlation between SUVmax, histopathology outcomes and tumor size in NSCLC. Further clinical trials should be performed in order to confirm our data
Conversion due to vascular injury during video-assisted thoracic surgery lobectomy: A multicentre retrospective analysis from the Italian video-assisted thoracic surgery group registry
Objectives: Vascular injuries are among the most severe causes of unplanned conversion during VATS lobectomies. The study aimed to analyse the incidence of vascular injuries and their risk factors during VATS lobectomy. Methods: The Italian VATS lobectomy Registry was used to collect data from 66 Thoracic Surgery Units. From 2013 to October 2016 (out of more than 3,700 patients enrolled) only information from Units with an enrollment >100 VATS lobectomies were retrospectively analysed. Logistic regression analysis was performed on selected variables of the univariate analysis. Results: Ten institutions contributed a total of 1,679 patients. Vascular injuries leading to conversion occurred in 44 (2.6%) patients. Years of experiences were inversely related to the risk of vascular injuries. Univariate analysis showed age, gender, surgical activity, Charlson Index Score and number of resected lymph nodes like significantly associated variables. Multivariate analysis revealed that number of resected lymph nodes, VATS experience ratio (number of VATS lobectomies/total lobectomies performed in the same year at same centre), and surgical activity of the centre were significantly associated with the risk of conversion. Unplanned thoracotomy was correlated with postoperative morbidity. Conclusion: Vascular injuries in VATS lobectomies represented a rare complication which could directly affect the postoperative outcomes. The predictive factors for conversion were multifactorial and depended on characteristics of centres and surgeons\u2019 seniority. Minimally invasive VATS lobectomy approaches did not influence the risk of vascular damages

Standardized uptake value and radiological density attenuation as predictive and prognostic factors in patients with solitary pulmonary nodules: Our experience on 1,592 patients
Background: Multislice computed tomography (MSCT) increased detection of solitary pulmonary
nodules (SPNs), changing the management based on radiological and clinical factors. When 18-fluorine
fluorodeoxyglucose positron emission tomography combined with computed tomography (18F-FDG-PET/CT)
was considered for the evaluation of nodules, the maximum standardized uptake value (SUVmax) more than 2.5
is used frequently as a cut off for malignancy. The purpose of this study is to evaluate SUVmax PET/CT and
pulmonary attenuation patterns at MSCT in patients with SPN according to morphological and pathological
characteristics of the lesion.
Methods: A retrospective study on 1,592 SPN patients was carried out following approval by the Italian
Registry of VATS Lobectomies.
Results: All patients underwent VATS lobectomy. On histologic examination, 98.1% had primary or
second metachronous primary lung cancers. In addition, 10.7% presented occult lymph node metastases
(pN1 or pN2) on histological examination. Nodule attenuation on CT was associated with the histology of
the lesion (p= 0.030); in particular, pure ground glass opacities (pGGOs) and partially solid nodules were
related to adenocarcinomatous histotypes. Conversely, a significant relationship between SUVmax and age,
nodule size, pathological node status (pN) was found (P=0.007, P=0.000 and P=0.002 respectively).
Conclusions: Nodule attenuation can predict the histology of the lesion whereas SUVmax may relate to
the propensity to lymph node metastases.
