Objectives: Aim of this study is to identify the factors that may influence the lymphadenectomy during VATS anatomical lung resection with particular interest on operator experience. Materials and methods: Clinical and pathological data from the prospective VATS Italian nationwide registry were reviewed and analysed. Patients with incomplete data regarding tumor and surgical characteristics, GGO, or with distant metastases were excluded. Patients clinical data, tumor characteristics, operation information and surgeon experience were collected and compared to resected lymph nodes number (#RN), resected N2 nodes number (#N2RN) and resected N2 stations number. A multivariable model was built using logistic regression analysis. Surgeon experience was categorized considering the number of VATS major anatomical resection and years after residency. Results: The final analysis was conducted on 3727 patients. The median #RN and #N2RN were 11 (1-51) and 5 (0-41). Regarding the analysed outcomes, #N2RN > 6 resulted in 1812 (48.8%)cases, #RN > 10 in 2124 (57.0%)cases and more than 3 N2 stations were harvested in 1447 (38.8%)patients. First operator experience with number of VATS lobectomies>50 (p < 0.001), operator seniority after residency5-10years (p < 0.001), cTNM II/III(p = 0.017), lobectomy/bilobectomy vs segmentectomy (p < 0.001), and upper/middle lobe tumor location (p < 0.005)resulted significantly associated to #N2RN > 6 at the multivariable analysis. First operator experience with number of VATS lobectomies>50 (p < 0.001), operator seniority after residency5-10years (p < 0.001) and lobectomy/bilobectomy (p < 0.001) resulted significantly associated to #RN > 10 at the multivariable analysis. Conclusions: Our study showed that lymphadenectomy during VATS lobectomy is influenced by tumor factors such as c

Background: Till now there are very few reports about surgical results of Uniportal-VATS esophagectomy and no one about long-term outcomes. This study is the first comparing surgical and oncological outcomes of Uniportal-VATS with open McKeown esophagectomy, with the largest reported series and longest oncological follow-up. Methods: The prospectively collected clinical, surgical and oncological data of 75 patients, undergone McKeown esophagectomy at our Thoracic Surgery Department, from January 2012 to August 2022, were retrospectively analyzed. Nineteen patients underwent esophagectomy by thoracotomy and reconstruction according to McKeown technique while 56 by Uniportal-VATS approach. Gastric tubulization was performed totally laparoscopic or through a mini-laparatomic access and cervical anastomosis was made according to Orringer's technique. Results: The mean operative thoracic time was similar in both accesses (102.34 ± 15.21 min in Uniportal-VATS vs. 115.56 ± 23.12 min in open, p: 0.646), with a comparable number of mediastinal nodes retrieved (Uniportal-VATS:13.40 ± 8.12 vs. open:15.00 ± 6.86, p: 0.275). No case needed conversion from VATS to open. The learning curve in Uniportal-VATS was completed after 34 cases, while the Mastery was reached after 40. Both approaches were comparable in terms of minor post-operative complications (like pneumonia, lung atelectasis, anemization, atrial fibrillation, anastomotic-leak, left vocal cord palsy, chylothorax), while the number of re-operation for major complications (bleeding or mediastinitis) was higher in open group (21.0% vs. 3.6%, p: 0.04). Both techniques were also effective in terms of surgical radicality and local recurrence but VATS approach allowed a significantly lower chest tube length (11.89 ± 9.55 vs. 25.82 ± 24.37 days, p: 0.003) and post-operative stay (15.63 ± 11.69 vs. 25.53 ± 23.33, p: 0.018). The 30-day mortality for complications related to surgery was higher in open group (p: 0.002). The 2-, 5

OBJECTIVES: Total thymectomy in addition to medical treatment is an accepted standard therapy for myasthenia gravis (MG). Patients with severe generalized MG present life-threatening events, poor prognosis and higher risk of postoperative myasthenic crisis. The aim of our study is to investigate neurological and surgical results in patients with Myasthenia Gravis Foundation of America (MGFA) class IV and V MG following thymectomy. METHODS: Data on 76 MG patients with preoperative MGFA classes IV and V who underwent thymectomy were retrospectively collected. Primary end points included short-term surgical outcomes and long-term neurological results including the achievement of complete stable remission and any improvement as defined by MGFA Post-Intervention Status criteria. RESULTS: There were 27 (35.5%) males and 49 (64.5%) females; 53 (69.7%) were classified as MGFA class IV and 23 (30.3%) as class V. Thymectomy was performed through sternotomy in 25 (32.9%) patients, Video-assisted thoracic surgery (VATS) in 5 (6.6%) and Robot-assisted thoracic surgery (RATS) in 46 (60.5%). The median operative time was 120 (interquartile range: 95; 148) min. In-hospital mortality was observed in 1 (1.3%) patient and postoperative complications in 14 (18.4%) patients. The median postoperative hospital stay was 4 (interquartile range: 3; 6) days. Pathological examination revealed 31 (40.8%) thymic hyperplasia/other benign and 45 (59.2%) thymomas. Cumulative complete stable remission and improvement probabilities were 20.6% and 83.7% at 5 years and 66.9% and 97.6% at 10 years, respectively. A significant improvement rate was found in patients with age at the time of thymectomy of <_50 years (P = 0.0236), MGFA class V (P = 0.0154) and acetylcholine receptor antibodies positivity (P = 0.0152). CONCLUSIONS: Thymectomy in patients with severe MG yields good perioperative outcomes and satisfactory long-term neurological improvement, especially for patients younger than 50 years, with

Background. Since no robust data are available on the real rate of unforeseen N1-N2 disease (uN) and the relative predictive factors in clinical-N0 NSCLC with peripheral tumours > 3 cm, the usefulness of performing a (mini)invasive mediastinal staging in this setting is debated. Herein, we investigated these issues in a nationwide database. Methods. From 01/2014 to 06/2020, 15,784 thoracoscopic major lung resections were prospectively recorded in the “Italian VATS-Group” database. Among them, 1982 clinical-N0 peripheral solid-type NSCLC > 3 cm were identified, and information was retrospectively reviewed. A mean comparison of more than two groups was made by ANOVA (Bonferroni correction for multiple comparisons), while associations between the categorical variables were estimated with a Chi-square test. The multivariate logistic regression model and Kaplan–Meyer method were used to identify the independent predictors of nodal upstaging and survival results, respectively. Results. At pathological staging, 229 patients had N1-involvement (11.6%), and 169 had uN2 disease (8.5%). Independent predictors of uN1 were SUVmax (OR: 1.98; CI 95: 1.44–2.73, p = 0.0001) and tumour-size (OR: 1.52; CI: 1.11–2.10, p = 0.01), while independent predictors of uN2 were age (OR: 0.98; CI 95: 0.96–0.99, p = 0.039), histology (OR: 0.48; CI 95: 0.30–0.78, p = 0.003), SUVmax (OR: 2.07; CI 95: 1.15–3.72, p = 0.015), and the number of resected lymph nodes (OR: 1.03; CI 95: 1.01–1.05, p = 0.002). Conclusions. The unforeseen N1-N2 disease in cN0/NSCLCs > 3 cm undergoing VATS resection is observable in between 12 and 8% of all cases. We have identified predictors that could guide physicians in selecting the best candidate for (mini)invasive mediastinal staging.

In the last decade, the emergence of effective systemic therapies (ESTs) in the form of both targeted and immuno-based therapies has revolutionized the treatment of patients with advanced stage III and stage IV melanoma. Even though lungs represent the most frequent site of melanoma metastases, only limited data are available on the role of surgery in isolated pulmonary metastases from malignant melanoma (PmMM) in the era of ESTs. The aim of this study is to describe the outcomes of patients who underwent metastasectomy of PmMM in the era of ESTs, in order to identify prognostic factors affecting survival and to provide a framework for more informed patient selection of treatmeant with lung surgery in the future. Clinical data of 183 patients who underwent metastasectomy of PmMM between June 2008 and June 2021 were collected among four Italian Thoracic Centers. The main clinical, surgical and oncological variables reviewed were: sex, comorbidities, previous oncological history, melanoma histotypes and primary site, date of primary cancer surgical treatment, melanoma growth phase, Breslow thickness, mutation pattern disease, stage at diagnosis, metastatic sites, DFI (Disease Free Interval), characteristics of lung metastases (number, side, dimension, type of resection), adjuvant therapy after lung metastasectomy, site of recurrence, disease-free survival (DFS) and cancer-specific survival (CSS; defined as the time interval between the first melanoma resection or lung metastasectomy and death from cancer). All patients underwent surgical resection of the primary melanoma before lung metastasectomy. Twenty-six (14.2%) patients already had a synchronous lung metastasis at the time of primary melanoma diagnosis. A wedge resection was performed in 95.6% of cases to radically remove the pulmonary localizations, while an anatomical resection was necessary in the remaining cases. The incidence of major post-operative complications was null, while only 21 patients (11.5%) dev

BackgroundAlthough the feasibility and safety of Uniportal-Video-Assisted thoracic surgery (U-VATS) has been proven, its surgical effectiveness is still debated. The aim of this study is to assess the equivalence of the U-VATS approach compared with an open technique in terms of surgical (nodal-upstaging, complications, and post-operative results) and short-term survival outcomes. MethodsThe clinical data of patients undergoing lobectomy for NSCLC at our center, from January 2014 to December 2019, were analyzed retrospectively. All patients undergoing open or U-VATS lobectomy with lymphadenectomy for early-stage lung cancer (cT1-T3N0, stages IA-IIB) were included in the study. Only 230 patients satisfied the inclusion criteria. Group bias was reduced through 1:1 propensity score matching, which resulted in 46 patients in each group (open surgery and U-VATS). ResultsThe intra- and post-operative mortality were null in both groups. There was no difference in the post-operative complications (p: 1.00) between U-VATS and open lobectomy. There was also no recorded difference in the pathological nodal up-staging [11 (23.9%) after thoracotomy vs. 8 (17.4%) after U-VATS, p: 0.440). The chest tube duration was longer in the open group (p: 0.025), with a higher post-operative pain (p: 0.001). Additionally, the 3-year overall survival (OS) was 78% after U-VATS lobectomy vs. 74% after open lobectomy (p: 0.204), while 3-year disease-specific survival (DSS) was 97 vs. 89% (p: 0.371), respectively. The 3-year disease-free survival (DFS) was 62% in the U-VATS group and 66% in the thoracotomy group, respectively (p: 0.917). ConclusionsUniportal-VATS lobectomy for the treatment of early-stage lung cancer seems to be a safe and effective technique with similar surgical and short-term survival outcomes as open surgery, but with lower post-operative pain and shorter in-hospital stay.

Objectives The study aimed to assess the feasibility of radical surgical treatment for selected bone-oligometastatic non-small cell lung cancer (NSCLC) patients and to identify prognostic factors associated with survival. Materials and methods The clinical records of 27 patients with bone synchronous oligometastatic NSCLC were retrospectively analyzed. Results Thirteen (48.1%) bone metastases were treated by surgery and 14 (51.9%) by local radiotherapy. Eighteen (66.7%) patients underwent induction chemotherapy before lung surgery, and 3 (11.1%) concurrent radiotherapy. Pulmonary surgery was a major lung resection in 23 (85.2%) cases. Intraoperative and 30-days mortality was null. Only one major (ARDS) and 10 (37.04%) mild complications (like air leakage, arrhythmia, and mucus retention) were recorded. 1-year and 5-years OS from the diagnosis and 1-year, 3- years disease-free survival (DFS) were 96%, 38%, and 66%, 30%, respectively. After stepwise Cox regression analysis, local recurrence (p = 0.05) and metachronous metastases (p = 0.04) maintained their independent prognostic value as overall survival negative determinants. Nodal upstaging (p = 0.04) and nonsurgical treatment of bone lesion (p = 0.03) turned out to be independent risk factors for shorter DFS; the vertebral localization of bone metastases showed only a remarkable trend towards significance (p = 0.06) as a risk factor for a worse DFS. Conclusions In selected patients, surgical treatment of primary NSCLC and bone synchronous metastasis seems to be safe and feasible and rewarding survivals may be expected.

BACKGROUND: The aim of this study is to analyze the prognostic factors in patients that underwent induction therapy and surgery for clinical stage III NSCLC. METHODS: Clinical and pathological characteristics of stage III NSCLC patients for N2 involvement that underwent neoadjuvant treatment (NAD) and surgery from 1/01/1998 to 31/12/2017 were collected and retrospectively analyzed. Tumor characteristics, yClinical, yPathological stage and lymph node characteristics were correlated to Overall Survival (OS). RESULTS: The analysis was conducted on 180 patients. Five-year OS (5YOS) was 50.9%. Univariable analysis results revealed old age (p = 0.003), clinical N2 post-NAD (p = 0.01), pneumonectomy (0.005), persistent pathological N2 (p = 0.039, HR 1.9, 95% CI 1.09-2.68) and adjuvant therapy absence (p = 0.049) as significant negative prognostic factors. Multivariable analysis confirmed pN0N1 (p = 0.02, HR 0.29, 95% CI 0.13-0.62) as a favorable independent prognostic factor and adjuvant therapy absence (p = 0.012, HR 2.61, 95% CI 1.23-5.50) as a negative prognostic factor. Patients with persistent N2 presented a 5YOS of 35.3% vs. 55.8% in pN0N1 patients. Regarding lymph node parameters, the lymph node ratio (NR) significantly correlated with OS: 5YOS of 67.6% in patients with NR < 50% vs. 29.5% in NR > 50% (p = 0.029). CONCLUSION: Clinical response aided the stratification of prognosis in patients that underwent multimodal treatment for stage III NSCLC. Adjuvant therapy seemed to be an important option in these patients, while node ratio was a strong prognosticator in patients with persistent nodal involvement.

Background and Objectives The Masoka-Koga and tumor node metastases staging systems for thymoma are based on structures involved, but the prognostic role of the number of infiltrated/involved structures is still debated. We analyzed the prognostic role of involved structures and their combinations in locally advanced thymomas patients. Methods Data on 174 surgically treated locally advanced thymoma patients from 1/01/1990 to 31/12/2015 were reviewed. Clinical and pathological characteristic, involved structures, number of involved structures and different combinations were correlated to cancer specific survival (CSS) using Kaplan-Meier product-limit method. Results Five and 10-year CSS was 92% and 87%. Masaoka Stage 3 (p < 0.001), absence of pericardial involvement (p = 0.001), number of involved structures (p = 0.018), R0 (p < 0.001) and adjuvant radiotherapy (p = 0.008) were favorable prognostic CSS factors. A significant better prognosis was present in <= 2 involved structures vs >2 involved structures (5- and 10-year CSS: 95% and 93% vs. 80% and 51%). Multivariable analysis confirmed as independent prognostic factor R0 (p = 0.033, hazard ratio [HR]: 0.093, 95% confidence interval [CI] 0.010-0.827) and number of involved structures (p = 0.046, HR: 0.187, 95% CI: 0.036-0.968). In Masaoka Stage 3, patients with <= 2 involved structures had a significant better CSS than patients with >2 (10-year CSS: 98% vs. 73%, p = 0.008). Conclusions The number of involved structures and the concomitant involvement of the pericardium seems to be associated with a poor prognosis in surgically treated advanced thymoma patients.

BACKGROUND: The optimal thoracoscopic sympathetic surgery for primary palmar and/or axillary hyperhidrosis (PPAH) is still unclear because of lack of uniform technique and qualitative/quantitative scales for definition of results. The aims of this study were to compare long-term outcomes based on the surgical technique and the level of sympathetic trunk interruption by clipping and to assess postoperative compensatory sweating (CS), patients' satisfaction, and quality of life (QoL).MATERIALS AND METHODS: Between September 2009 and April 2016, 94 patients who underwent 2-stage bilateral thoracoscopic rib-oriented (R) sympathetic clipping were prospectively followed up through the administration of standardized preoperative and postoperative questionnaires.Thirty-four (36.2%) patients underwent single-port transaxillary access instead of the standard two 5-mm incisions. The level of sympathetic clipping for PPAH was R3+4(top and bottom); in patients who complained associated facial or plantar hyperhidrosis R2-bottom and R5-top were clipped, respectively. Seventy-five patients completed bilateral surgery.RESULTS: There were no significant differences between single-port and biportal video-assisted thoracoscopic surgery in terms of operative times and postoperative results. At a mean follow-up of 72 (SD: 26) months, CS was reported in 42 (56%) patients, severe only in 6 (8%). It was higher in the case of R2-bottom clipping (P=0.03). Thirty-one of 60 (51.6%) patients who had a plantar hyperhidrosis declared an improvement of feet sweating after surgery. Postoperative satisfaction was excellent (86.11% on a 0 to 100 scale) and 95.4% of patients declared an improvement in QoL, which was statistically significant in all evaluated parameters. These results were not related to the level of clipping.CONCLUSION: Thoracoscopic R3 to R4 clipping appears to be a safe and effective treatment for PPAH. Although postoperative CS was common and higher after R2-bottom clipping, this di

Background: Descending necrotizing mediastinitis (DNM) is a severe, life-threatening complication of oropharyngeal infections with cervical necrotizing fasciitis. In this study, we aimed to identify any possible factors that correlate with favorable outcomes. Methods: We retrospectively analyzed our series of 18 patients who underwent surgical treatment for DNM from a cervical abscess. Gender, age, symptoms, etiopathogenesis, comorbidities, time to surgery from diagnosis, degree of diffusion, identified microorganisms, surgical procedure, days in the intensive care unit, need for tracheostomy, complications, and surgical outcomes were reviewed. Results: The main type of surgery was thoracotomy + cervicotomy in eight cases (50.0%), followed by cervicotomy +VATS in four (22.2%). Seven patients (38.9%) had two or more surgeries; a bilateral operation was necessary for four patients. Evaluating the risk factors associated with post-operative complications, age ≥ 60 years (p:0.031), cervicotomy alone as surgical approach (p = 0.040), and the bilateral approach (p = 0.048) resulted in significance in terms of the univariate analysis; age ≥ 60 years (p = 0.04) and cervical approach (p = 0.05) maintained their significance in terms of the multivariate analysis. Conclusions: The low mortality of our series emphasizes the importance of an extensive and immediate surgical drainage of both the neck and the mediastinum. Mediastinal drainage from cervicotomy seems to be a risk factor for post-operative complications. Minimally invasive surgery on the chest cavity, such as with Uniportal-VATS, could be a good approach above all in elderly patients and all those cases where bilateral access is required.

Background: Robot-assisted thymectomy (RAT) has rapidly emerged as the preferred approach over open trans-sternal or video-assisted thoracoscopy for the surgical treatment of thymomas and non-thymomatous myasthenia gravis (MG). The aim of this study was to describe and discuss the learning curve (LC) of a single surgeon performing 113 consecutive RATs. Methods: A single-center retrospective analysis of prospectively collected clinical data was performed on all patients who had been operated on by the same surgeon in an RAT setting between October 2013 and February 2020. The cumulative sum (CUSUM) analysis of the operative time was used to define the completion of the learning curve (CLC) in RAT. The CLC was separately calculated for myasthenic patients, non-myasthenic patients, and docking time. Results: In myasthenic patients, the CLC cut-off was found in 19 patients. Considering the CLC cut-off of 19 patients, the mean operative time in phase 1 (first 19 cases) was 229.79 ± 93.40 min, while it was 167.35 ± 41.63 min in phase 2 (last 51 cases), (Formula presented.). In non-myasthenic patients, the CLC cut-off was found in 16 cases. The mean operative time in phase 1 (first 16 cases) was 277.44 ± 90.50 min, while it was 169.63 ± 61.10 min in phase 2 (last 27 cases), p = 0.016. The LC for docking time was reached at 46 cases, recording a significant reduction of time after the first phase (28.09 ± 5.37 min vs. 19.75 ± 5.51 min, (Formula presented.)). The intraoperative and 30-day mortality were null in all phases of the LC in both myasthenic and non-myasthenic patients. There were no differences between the two phases of the LC in terms of blood loss, duration of postoperative drainage, and postoperative stay in both myasthenic and non-myasthenic groups. However, significantly higher hospital readmission at 30 days post surgery was recorded for myasthenic patients operated on during the first phase of the LC (2 cases vs. 0, p = 0.02). Conclusions: According to our da

OBJECTIVES: Lung metastases from gynaecological tract cancers are rare, and prognostic factors are still undefined. The goal of this study was to analyse prognostic factors for survival in this group of patients. METHODS: Data of patients with lung metastases from gynaecological tract cancers who underwent surgical resections from 1 January 2005 to 31 May 2019 were reviewed retrospectively. All patients were treated surgically if the primitive tumour was under control and the lung was the only organ involved. Clinical and pathological data associated with metastatic patterns and previous treatment types were correlated with overall survival (OS) and disease-free survival using Kaplan-Meier curves, whereas the log-rank test was used to assess differences between subgroups. RESULTS: The analysis was conducted on 55 patients. OS was 65% at 5 years. With univariable analysis, age >45 years (P = 0.022) and the absence of pleural infiltration (P = 0.001) were determined to be favourable prognostic factors. The 5-year OS was 69.9% versus 53.3% in patients with pleural involvement. Multivariable analysis confirmed the absence of pleural infiltration as a favourable independent prognostic factor; the hazard ratio was 0.06; the 95% confidence interval was 0.00-0.23 (P = 0.011).At univariable analysis, the absence of pleural infiltration was determined to be a favourable prognostic factor (P = 0.034) for disease-free survival. The numbers and dimensions of the metastases did not influence survival in these patients.In uterine cancers of endometrial or cervical origin, the presence of pleural infiltration (P = 0.001), lymph node involvement (P = 0.001) and young age (P = 0.044) were considered unfavourable prognostic factors for OS. CONCLUSIONS: Surgical treatment in technically resectable gynaecological tract metastases may represent an important option. Pleural infiltration and lymph node metastases seem to be adverse prognostic factors.
