Introduction: The standard surgical procedures for patients with early-stage NSCLC is lobectomy-associated radical lymphadenectomy performed by using the thoracotomy approach. In the last few years, minimally invasive techniques have increasingly strengthened their role in lung cancer treatment, especially in the early stage of the disease. Although the lobectomy technique has been accepted, controversy still surrounds lymph node dissection. In our study, we analyze the rate of upstaging early non-small cell lung cancer patients who underwent radical surgical treatment using the robotic and the VATS techniques compared to the standard thoracotomy approach.Methods and Materials: We retrospectively reviewed patients who underwent a lobectomy and radical lymphadenectomy at our Institute between 2010 and 2019. We selected 505 patients who met the inclusion criteria of the study: 237 patients underwent robotic surgery, 158 patients had thoracotomy, and 110 patients were treated with VATS. We analyzed the demographic features between the groups as well as the nodal upstaging rate after pathological examination, the number of dissected lymph nodes and the ratio of dissected lymph nodes to metastatic lymph nodes of the three groups.Results: The patients of the three groups were homogenous with respect to age, sex, and histology. The postoperative major morbidity rate was significantly higher in the thoracotomy group, and hospital stay was significantly longer. The percentage of the mediastinal nodal upstaging rate and the number of dissected lymph nodes was significantly higher in the robotic group compared with the VATS group. The ratio of dissected lymph nodes to metastatic lymph nodes was significantly lower compared with the VATS group and the thoracotomy group.Discussion: The prognostic impact of the R(un) status is still highly debated. A surgical approach that allows better results in terms of resection has still not been defined. Our results show that robotic surgery is a safe and feasible approach especially regarding the accuracy of mediastinal lymphadenectomy. These findings can lead to defining a more precise pathological stage of the disease and, if necessary, to more accurate postoperative treatment.

We believe that the transthoracic approach is a safe and effective method for repairing Morgagni's hernia. The videothoracoscopic approach is a promising alternative and it may be facilitated by introducing a hand inside the chest.

Background. Optimal management of emphysematous patients who have lost the benefits achieved after lung volume reduction surgery is a clinical dilemma. We have hypothesized that in stringently selected instances, lung volume reduction reoperations might be considered as a salvage surgical treatment. We sought to analyze the results of a series of patients undergoing lung volume reduction reoperations after successful bilateral lung volume reduction surgery.Methods. Between January 2000 and April 2006, 17 patients (mean age, 66 ؎ 3 years) with radiologic evidence of distinct regional lung hyperinflation underwent lung volume reduction reoperations. Surgical procedures entailed completion lobectomy in 7 patients, nonanatomic resection of lung target areas were performed in 5 patients under general anesthesia with one-lung ventilation, and awake lung plication was performed in 5 patients under sole epidural anesthesia. Follow-up at 6 and 12 months was complete in all survivors.Results. Mean operative time was 100 ؎ 12 minutes. Two patients (11.7%) died perioperatively of adult respi-

Despite the intense debate concerning management of advanced thymic tumors, no specific oncological strategies have been yet recommended. We report our 13 years' experience to investigate this issue. From 01/2001 to 12/2013, the clinical data of 28 patients treated for Masaoka stages III-IV thymic tumors were retrospectively reviewed. Eleven potentially nonresectable patients (Group A) underwent induction chemotherapy plus surgery, while immediate surgery was performed in 17 patients (Group B). The endpoint was to compare the two groups on (1) surgical resectability; (2) postoperative course; (3) disease-free survival; and (4) overall survival. Both groups were comparable in terms of age, gender, clinical stage, clinical tumor size, histology, and adjuvant therapy. Length of surgery was statistically longer in Group A ( = 0.015). Combined surgery and R0 resection was similarly performed in both groups ( = 0.14 and = 0.99, respectively). The 3-year overall survival was 71.4% for Group A and 93.3% for Group B ( = 0.84). On the other hand, 3-year disease-free survival was 40.5 and 53.7% for Group A and B, respectively ( = 0.67). At multivariate analysis, gender was the strongest predictor for recurrence (hazard ratio = 5.71 [1.22; 26.67], = 0.03). Our results suggest that induction therapy allows obtaining acceptable clinical responses as well as resectability, survival, and recurrence rates. In selected patients with "clinically resectable" stage III-IV cancers, surgery (as first step of a multimodality therapy) could be a feasible treatment option.

Background: While the thoracotomy approach was considered the gold standard until two decades ago, robotic surgery has increasingly strengthened its role in lung cancer treatment, improving patients’ peri-operative outcomes. In this study, we report our experience in robotic lobectomy for early-stage non-small cell lung cancer, with particular attention to oncological outcomes and nodal upstaging rate. Methods: We retrospectively reviewed patients who underwent lobectomy and radical lymphadenectomy at our Institute between 2016 and 2020. We selected 299 patients who met the inclusion criteria of the study. We analyzed the demographic features of the groups as well as their nodal upstaging rate after pathological examination. Then, we analyzed disease-free and overall survival of the entire enrolled patient population and we compared the same oncological outcomes in the upstaging and the non-upstaging group. Results: A total of 299 patients who underwent robotic lobectomy were enrolled. After surgery, 55 patients reported nodal hilar or mediastinal upstaging. The 3-year overall survival of the entire population was 82.8%. The upstaging group and the non-upstaging group were homogeneous for age, gender, smoking habits, clinical stage, tumor site, tumor histology. The non-upstaging group had better OS (p = 0.004) and DFS (p < 0.0001). Conclusion: Our results show that robotic surgery is a safe and feasible approach for the treatment of early-stage NSCLC, especially for its accuracy in mediastinal lymphadenectomy. The oncological outcomes were encouraging and consistent with previous findings.
