BACKGROUND: Non-small Cell Lung Cancer (NSCLC) with intralobar satellite nodule are defined as T3 (T3SN). We investigated the main features of these tumors and analyzed their impact on Overall Survival (OS). METHODS: This was a retrospective multicentric study including all pT3SN NSCLC operated on between 2005 and 2020, excluding patients with multifocal ground-glass opacities; who received induction therapies; N3 or stage IV. The diameter of largest (LgN) and smallest nodule (SmN), the total diameter (sum of diameter of all nodules, TS), and the number of SN were measured. RESULTS: Among 102 patients, 64.7 % were male. 84.3 % of patients had one SN (84.3 %), 9.8 % two SN while 5.9 % more than 2 SN. 63 patients were pN0. LgN (p = 0.001), SN (p = 0.005) and TS (p = 0.014) were significantly related to lymph-node metastasis; the LgN and TS were related to visceral pleural invasion (p < 0.001). Five-year OS was 65.1 %; at univariable analysis more than 2 satellite nodules, LgN and TS were significantly related to worse OS; at multivariable analysis, TS (Hazard Ratio [HR] 1.116 95 % Confidence Interval [CI] 1.008-1.235, p = 0.034) was an independent prognostic factors for OS. No significant prognostic factors were found for DFS at multivariable analysis. In pN0 patients, LgN (HR 1.051, 95 % CI 1.066-1.099, p = 0.027) and non-adenocarcinoma (HR 5.315 CI 95 % 1.494-18.910, p = 0.010) influenced OS. CONCLUSIONS: Tumor size is related to tumor's local invasiveness. TS is an independent prognostic factor for OS. Patients with more than 2 SN seem to be at higher risk for death and recurrence.

OBJECTIVES: Robotic thymectomy has been suggested and considered technically feasible for thymic tumours. However, because of small-sample series and the lack of data on long-term results, controversies still exist on surgical and oncological results with this approach. We performed a large national multicentre study sought to evaluate the early and long-term outcomes after robot-assisted thoracoscopic thymectomy in thymic epithelial tumours. METHODS: All patients with thymic epithelial tumours operated through a robotic thoracoscopic approach between 2002 and 2022 from 15 Italian centres were enrolled. Demographic characteristics, clinical, intraoperative, postoperative, pathological and follow-up data were retrospectively collected and reviewed. RESULTS: There were 669 patients (307 men and 362 women), 312 (46.6%) of whom had associated myasthenia gravis. Complete thymectomy was performed in 657 (98%) cases and in 57 (8.5%) patients resection of other structures was necessary, with a R0 resection in all but 9 patients (98.6%). Twenty-three patients (3.4%) needed open conversion, but no perioperative mortality occurred. Fifty-one patients (7.7%) had postoperative complications. The median diameter of tumour resected was 4 cm (interquartile range 3-5.5 cm), and Masaoka stage was stage I in 39.8% of patients, stage II in 56.1%, stage III in 3.5% and stage IV in 0.6%. Thymoma was observed in 90.2% of patients while thymic carcinoma occurred in 2.8% of cases. At the end of the follow-up, only 2 patients died for tumour-related causes. Five- and ten-year recurrence rates were 7.4% and 8.3%, respectively. CONCLUSIONS: Through the largest collection of robotic thymectomy for thymic epithelial tumours we demonstrated that robot-enhanced thoracoscopic thymectomy is a technically sound and safe procedure with a low complication rate and optimal oncological outcomes.

Introduction: Robotic and thoracoscopic surgery are being increasingly adopted as minimally invasive alternatives to open sternotomy for complete thymectomy. The superior maneuverability range and three-dimensional magnified vision are potential ergonomical advantages of robotic surgery. To compare the ergonomic characteristics of robotic versus thoracoscopic thymectomy, a previously developed scoring system based on impartial findings was employed. The relationship between ergonomic scores and perioperative endpoints was also analyzed. Methods: Perioperative data of patients undergoing robotic or thoracoscopic complete thymectomy between January 2014 and December 2022 at three institutions were retrospectively retrieved. Surgical procedures were divided into four standardized surgical steps: lower-horns, upper-horns, thymic veins and peri-thymic fat dissection. Three ergonomic domains including maneuverability, exposure and instrumentation were scored as excellent(score-3), satisfactory(score-2) and unsatisfactory(score-1) by three independent reviewers. Propensity score matching (2:1) was performed, including anterior mediastinal tumors only. The primary endpoint was the total maneuverability score. Secondary endpoints included the other ergonomic domain scores, intraoperative adverse events, conversion to sternotomy, operative time, post-operative complications and residual disease. Results: A total of 68 robotic and 34 thoracoscopic thymectomies were included after propensity score matching. The robotic group had a higher total maneuverability score (p = 0.039), particularly in the peri-thymic fat dissection (p = 0.003) and peri-thymic fat exposure score (p = 0.027). Moreover, the robotic group had lower intraoperative adverse events (p = 0.02). No differences were found in residual disease. Conclusions: Robotic thymectomy has shown better ergonomic maneuverability compared to thoracoscopy, leading to fewer intraoperative adverse events and comparable early oncological results.
RESUMEN
The conventional supine position for robotic thymectomy may present challenges in accessing the lower thymic horns, particularly in cases requiring extensive resection of mediastinal fat. To address this issue, the authors advocate for a lateral patient position during the procedure, emphasizing optimized access to the thymic horns and improved procedural efficacy. The lateral approach involves specific trocar placements and port arrangements to minimize conflicts between instruments. This report proposes an innovative approach to robotic thymectomy for patients diagnosed with thymoma or thymic hyperplasia associated with myasthenia gravis.

Thymectomy is the gold standard in the treatment of thymic neoplasm and plays a key role in the therapeutic path of myasthenia gravis. For years, sternotomy has been the traditional approach for removing anterior mediastinal lesions, although the robotic thymectomy is now widely performed. The literature is still lacking in papers comparing the two approaches and evaluating long-term oncological and neurological outcomes. This study aims to analyze the postoperative results of open and robotic thymectomy for thymic neoplasms in myasthenic patients. Surgical, oncological and neurological data of myasthenic patients affected by thymic neoplasms and surgically treated with extended thymectomy, both with the open and the robotic approach, in six Italian Thoracic Centers between 2011 and 2021 were evaluated. A total of 213 patients were enrolled in the study: 110 (51.6%) were treated with the open approach, and 103 (48.4%) were treated with robotic surgery. The open surgery, compared with the robotic, presented a shorter operating time (p < 0.001), a higher number of postoperative complications (p = 0.038) and longer postoperative hospitalization (p = 0.006). No other differences were observed in terms of surgical, oncological or neurological outcomes. The robotic approach can be considered safe and feasible, comparable to the open technique, in terms of surgical, oncological and neurological outcomes.

Background: Despite notable advances made in preoperative staging, unexpected nodal metastases after surgery are still significantly detected. In this study we aim to analyze the upstaging rate in patients with clinical stage I NSCLC without evidence of nodal disease in the preoperative staging who underwent lobectomy and radical lymphadenectomy. Methods: Patients who underwent lobectomy and systematic lymphadenectomy for clinical stage I NSCLC were evaluated. Exclusion criteria included the neoadjuvant treatment, incomplete resection and no adherence to preoperative guidelines. Results: A total of 297 patients were included in the study. 159 patients were female, and the median age was 68 (61 - 73). The variables that showed a significant correlation with the upstaging rate at the univariate analysis were the number of resected lymph nodes and micropapillar/solid adenocar-cinoma subtype. This result was confirmed in the multivariate analysis with a OR= 2.545 (95%CI 1.136-5.701; p=0.02) for the number of resected lymph nodes and a OR=2.717 (95%CI 1.256-5.875; p=0.01) for the high-grade pattern of adenocarcinoma. Conclusion: Our results showed that in a homogeneous cohort of patients with clinical stage I NSCLC, the number of resected lymph nodes and the histological subtype of adenocarcinoma can significantly be associated with nodal metastasis.
RESUMEN
The use of neoadjuvant or perioperative anti-PD(L)1 was recently tested in multiple clinical trials. We performed a systematic review and meta-analysis of randomised trials comparing neoadjuvant or perioperative chemoimmunotherapy to neoadjuvant chemotherapy in resectable NSCLC. Nine reports from 6 studies were included. Receipt of surgery was more frequent in the experimental arm (odds ratio, OR 1.39) as was pCR (OR 7.60). EFS was improved in the experimental arm (hazard ratio, HR 0.55) regardless of stage, histology, PD-L1 expression (PD-L1 negative, HR 0.74) and smoking exposure (never smokers, HR 0.67), as was OS (HR 0.67). Grade > = 3 treatment-related adverse events were more frequent in the experimental arm (OR 1.22). The experimental treatment improved surgical outcomes, pCR rates, EFS and OS in stage II-IIIB, EGFR/ALK negative resectable NSCLC; confirmatory evidence is warranted for stage IIIB tumours and with higher maturity of the OS endpoint.

Even though the use of the "fissure-last" technique in mini-invasive lobectomy with the fissureless condition is well accepted, in terms of perioperative outcomes, controversies still surround the hilar lymph node dissection. In this article, we reported a description of the robotic "tunnel technique" approach in the right upper lobectomy in the absence of a defined fissure. We then compared the short terms outcomes of 30 consecutive cases treated using this technique, with 30 patients treated using the "fissure last" VATS approach in the same institution, before the start of the robotic surgery program.

OBJECTIVES: Despite notable advances made in preoperative staging, unexpected nodal metastases after surgery are still significantly detected. Given the promising role of neoadjuvant targeted treatments, the definition of novel predictive factors of nodal metastases is an extremely important issue. In this study we aim to analyze the upstaging rate in patients with early stage NSCLC without evidence of nodal disease in the preoperative staging who underwent lobectomy and radical lymphadenectomy. MATERIAL AND METHODS: Patients who underwent lobectomy and systematic lymphadenectomy for early stage LUAD without evidence of nodal disease at the preoperative staging using NGS analysis for actionable molecular targets evaluation after surgery were evaluated. Exclusion criteria included the neoadjuvant treatment, incomplete resection and no adherence to preoperative guidelines. RESULTS: A total of 359 patients were included in the study. 172 patients were female, and the median age was 68 (61-72). The variables that showed a significant correlation with the upstaging rate at the univariate analysis were the ALK rearrangement, the number of resected lymph nodes and the diameter of the tumor. This result was confirmed in the multivariate analysis, with an OR of 8.052 (CI95% 3.123-20.763, p = 0.00001) for ALK rearrangement, 1.087 (CI95% 1.048-1.127, p = 0.00001) for the number of resected nodes and 1.817 (CI95% 1.214-2.719, p = 0.004) for cT status. CONCLUSION: Our results showed that in a homogeneous cohort of patients with clinical node early stage LUAD the ALK rearrangement, the number of resected lymph nodes and the tumor diameter can significantly predict nodal metastasis.

The primary objectives of the study were to analyse the robotic approach and ultrasound-guided paravertebral block compared to thoracoscopic intercostal nerve block after robotic pulmonary lobectomy on postoperative pain and opioids use. The secondary objectives were to analyse and compare patients' necessity of additional antalgic drugs and patients' performance during respiratory therapy, following robotic surgery and in the two groups. Consecutively, 52 patients undergoing robotic pulmonary lobectomies were treated either with ropivacaine-based intercostal nerve block or paravertebral block from February 2022 to October 2022. When necessary, morphine was administered at day 1. Acetaminophen was administered as an additional antalgic drug on demand up to 3 g per day. Pain was measured 1 h after the end of the surgical procedure and daily through the pain numeric rating scale (NRS). Morphine administration rate and per day and total additional administrations of acetaminophen were recorded. Pain and opioids administration was measured 1 month after the procedure. Data were analysed in the overall population and in the intercostal nerve block group VS paravertebral block group. Overall, 34.6% of the patients required morphine administration and 51.7% of the patients required at least daily acetaminophen administration up to discharge. At 1 month postoperatively, four patients presented with chronic pain and one still was under opioid medication. At intergroup analysis, the paravertebral block group demonstrated lower NRS at fixed time points (p < 0.0001) and lower morphine consumption (45.7%VS11.8%; p = 0.02). Acetaminophen rescue administration at fixed time points was lower in the paravertebral block group (p < 0.0001) and mobility and dynamic pain resulted in better results (p = 0.03; p = 0.04). At 1 month, no differences were found between study groups. Similarly to other minimally invasive techniques, postoperative pain may arise after robotic pulmonary lobectomy. Paravertebral bloc can help to reduce postoperative pain as well as morphine and antalgic drugs administration and improve early mobilization.

Given the high rate of small lung nodules detected during the oncological follow up for various cancers, in the era of personalize medicine, the histological diagnosis is of paramount importance. Usually, the small peripheral lung nodules are historically reached using a CT guided biopsy but this technique is characterized by an high rate of pneumothorax. Endoscopic procedures were referred only for central tumor that occluded the mains bronchi. In the last few years, the spreading of EBUS-TBNA, EUS-FNA and the navigational bronchoscopy systems has increase the use of these technique also for the diagnosis of small lung nodules.

BACKGROUND: Despite the lack of evidence-based on prospective randomized studies, surgery has become the cornerstone of the treatment in patients with pulmonary oligometastatic sarcomas. Our study aimed to construct a composite prognostic score for metachronous oligometastatic sarcoma patients. METHODS: A retrospective analysis was performed on data patients who underwent radical surgery for metachronous metastases in six research institutes from January 2010 to December 2018. The log-hazard ratio (HR) obtained from the Cox model was used to derive weighting factors for a continuous prognostic index designed to identify differential outcome risks. RESULTS: A total of 251 patients were enrolled in the study. In the multivariate analysis, a longer disease-free interval (DFI) and a lower neutrophil-to-lymphocytes ratio (NLR) were predictive of a better overall survival (OS) and disease-free survival (DFS). A prognostic score was developed based on DFI and NLR data, identifying 2 risk class groups for DFS (3-years DFS 20.2% for the high-risk group [HRG]and 46.4% for the low-risk group [LRG] [<0.0001]) and 3 risk groups for OS (3 years OS 53.9% for the HRG vs. 76.9% for the intermediate-risk group and 100% of the LRG (p < 0.0001)). CONCLUSION: The proposed prognostic score effectively predicts outcomes for patients with lung metachronous oligo-metastases from the surgically treated sarcoma.

Introduction: Minimally invasive surgery has become the standard for the early-stage non-small cell lung cancer (NSCLC). The appropriateness of the kind of lung resection for the elderly patients is still debated. Methods: We retrospectively reviewed patients with older than 75 years who underwent robotic lobectomy between May 2016 to June 2022. We selected 103 patients who met the inclusion criteria of the study. The preoperative cardiorespiratory functional evaluations were collected, and the risk of postoperative complications was calculated according to the Charlson Comorbidity Index, the American College of Surgery surgical risk calculator (ACS-NSQIP), EVAD score, and American Society of Anesthesiology (ASA) score. The patients were divided in two groups according to the presence of postoperative complications. Results: Forty-three patients were female, and 72.8% of the total population were former or active smokers. Thirty-five patients reported postoperative complications. The analysis of the two groups showed that the predicted postoperative forced expiratory volumes in the first second (FEV1) and forced vital capacity (FVC) were significantly lower in patients presenting postoperative complications (p=0.04). Moreover, the upstaging rate and the unexpected nodal metastases were higher in the postoperative complication groups. Conclusion: Robotic-assisted lobectomy for early-stage lung cancer is a safe and feasible approach in selected elderly patients. The factors that could predict the complication rate was the predicted postoperative FEV1 and the nodal disease.
RESUMEN
Background: Endoscopic ultrasound (EUS) plays an important role in the diagnosis and staging of thoracic disease. Our report studies the diagnostic performance and clinical impact of EUS fine needle aspiration (FNA) in a homogenous cohort of patients according to the distribution of the enlarged MLNs or pulmonary masses. Methods: We retrospectively reviewed the diagnostic performance of 211 EUS-FNA in 200 consecutive patients with enlarged or PET-positive MLNs and para-mediastinal masses who were referred to our oncological center between January 2019 and May 2020. Results: The overall sensitivity of EUS-FNA was 85% with a corresponding negative predictive value (NPV) of 56% and an accuracy of 87.5%. The sensitivity and accuracy in patients with abnormal MLNs were 81.1% and 84.4%, respectively. In those with para-mediastinal masses, sensitivity and accuracy were 96.4% and 96.8%. The accuracy for both masses and lymph nodes was 100%, and in the LAG (left adrenal gland), it was 66.6%. Conclusions: Our results show that, in patients with suspected mediastinal masses, EUS-FNA is an accurate technique to evaluate all reachable mediastinal nodal stations, including station 5.
RESUMEN
In the last few years, minimally invasive surgery has become the standard routine practice to manage lung nodules. Particularly in the case of robotic thoracic surgery, the identification of the lung nodules that do not surface on the visceral pleura could be challenging. Therefore, together with the evolution of surgical instruments to provide the best option in terms of invasiveness, lung nodule localization techniques should be improved to achieve the best outcomes in terms of safety and sensibility. In this review, we aim to overview all principal techniques used to detect the lung nodules that do not present the visceral pleura retraction. We investigate the accuracy of fluorescence guided thoracic surgery in nodule detection and the differences among the most common tracers used.
