National Multicenter Study on the Comparison of Robotic and Open Thymectomy for Thymic Neoplasms in Myasthenic Patients: Surgical, Neurological and Oncological Outcomes.

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.

Multicentre retrospective analysis on pulmonary metastasectomy: an European perspective.

OBJECTIVES: To assess the current practice of pulmonary metastasectomy at 15 European Centres. Short- and long-term outcomes were analysed. METHODS: Retrospective analysis on patients ≥18 years who underwent curative-intent pulmonary metastasectomy (January 2010 to December 2018). Data were collected on a purpose-built database (REDCap). Exclusion criteria were: previous lung/extrapulmonary metastasectomy, pneumonectomy, non-curative intent and evidence of extrapulmonary recurrence at the time of lung surgery. RESULTS: A total of 1647 patients [mean age 59.5 (standard deviation; SD = 13.1) years; 56.8% males] were included. The most common primary tumour was colorectal adenocarcinoma. The mean disease-free interval was 3.4 (SD = 3.9) years. Relevant comorbidities were observed in 53.8% patients, with a higher prevalence of metabolic disorders (32.3%). Video-assisted thoracic surgery was the chosen approach in 54.9% cases. Wedge resections were the most common operation (67.1%). Lymph node dissection was carried out in 41.4% cases. The median number of resected lesions was 1 (interquartile range 25-75% = 1-2), ranging from 1 to 57. The mean size of the metastases was 18.2 (SD = 14.1) mm, with a mean negative resection margin of 8.9 (SD = 9.4) mm. A R0 resection of all lung metastases was achieved in 95.7% cases. Thirty-day postoperative morbidity was 14.5%, with the most frequent complication being respiratory failure (5.6%). Thirty-day mortality was 0.4%. Five-year overall survival and recurrence-free survival were 62.0% and 29.6%, respectively. CONCLUSIONS: Pulmonary metastasectomy is a low-risk procedure that provides satisfactory oncological outcomes and patient survival. Further research should aim at clarifying the many controversial aspects of its daily clinical practice.

Robotic versus Open Surgery in Locally Advanced Non-Small Cell Lung Cancer: Evaluation of Surgical and Oncological Outcomes.

Locally advanced non-small cell lung cancer (NSCLC) consists of a heterogeneous group, with different pulmonary extension and lymph nodal involvement. Robotic surgery can play a key role in these tumours thanks to its technological features, although open surgery is still considered the gold-standard approach. Our study aims to evaluate the surgical and oncological outcomes of locally advanced NSCLC patients who underwent robotic surgery in a high-volume centre. Data from consecutive patients with locally advanced NSCLC who underwent robotic lobectomy were retrospectively analysed and compared with patients treated with open surgery. Clinical characteristics and surgical and oncological information were evaluated. From 2010 to 2020, 131 patients underwent anatomical lung resection for locally advanced NSCLC. A total of 61 patients were treated with robotic surgery (46.6%); the median hospitalization time was 5.9 days (range 2-27) and the postoperative complication rate was 18%. Open surgery was performed in 70 patients (53.4%); the median length of stay was 9 days (range 4-48) and the postoperative complication rate was 22.9%. The median follow-up time was 70 months. The 5-year overall survival was 34% in the robotic group and 31% in the thoracotomy group. Robotic surgery can be considered safe and feasible not only for early stages but also for the treatment of locally advanced NSCLC.

Comparison of Robotic and Open Lobectomy for Lung Cancer in Marginal Pulmonary Function Patients: A Single-Centre Retrospective Study.

BACKGROUND: The treatment of non-small-cell lung cancer (NSCLC) patients with reduced respiratory function represents a challenge for thoracic surgeons. Minimally invasive surgery seems to be beneficial for these patients because it reduces tissue trauma and its impact on respiratory mechanics. Application of the robotic technique, the use of CO2 insufflation and longer surgical time are factors that could influence the outcomes of marginal pulmonary function patients. The objective of this study was to evaluate the impact of the robotic technique on the postoperative outcomes of patients with poor lung function. METHODS: We retrospectively collected and analyzed data from consecutive marginal respiratory function patients who underwent robotic or open lobectomy for NSCLC. Data regarding clinical, operative and postoperative details were compared between the open and robotic approaches. RESULTS: The outcomes of 100 patients with reduced respiratory function were evaluated, of whom 59 underwent open lobectomies and 41 underwent robotic lobectomies. Robotic lobectomy was characterized by a longer operative time, a reduced hospital stay and a lower incidence of postoperative complications (22% vs. 33.9%), when compared to the open approach. CONCLUSION: Robotic lobectomy is a safe and feasible procedure for patients with marginal pulmonary function.

Women in thoracic, cardiac and vascular surgery claim for a change in the working situation: an Italian national survey.

Background: Women's participation in the surgical workforce has increased. The aim of the study is to acquire objective data regarding practice, training, satisfaction, and discrimination of women surgeons working in cardiothoracic and vascular surgery in Italy. Methods: An 83-item questionnaire was distributed through social media and sent to e-mails of women surgeons from November through December 2020. A sub-analysis on women working in cardiac, thoracic, and vascular surgery was performed. Results: Overall, 222 respondents were included (48 cardiac, 62 thoracic, and 112 vascular surgeons). Thirty-six percent partially abandoned surgical activities in favor of other professional activities, not including the operating room. On average, our respondents took part in 33% of all surgical cases performed in their units; however, of 12 high complexity surgeries per month, less than one is performed by them. Only 7 female participants who answered the questionnaire were in leadership positions. Many respondents struggle with lack of mentorship and missing opportunities in operating room. A high percentage of women experienced discrimination due to their gender in their professional life, and 59% claimed to have been subject to sexual harassment. Conclusions: In Italy, women thoracic, cardiac, and vascular surgeons face lack of mentorship, opportunities in the operating room, and gender-related issues including some episodes of sexual harassment. Diversity, equity, and inclusion should become strategic priorities in all institutions. Among our respondents, surgical exposure is limited, which may deter a surgical career and play a crucial role in surgeons' dissatisfaction, that also include poor work-life-balance, and a large amount of administrative work. Surgical societies may address these issues by providing structured mentorship programs and networking opportunities. Societies' contributions might substantially impact supporting and retaining women at different stages of their careers.

Case report: A giant lung leiomyosarcoma: From an accurate diagnosis to a successful surgery. A rare case and brief literature review.

Primary pulmonary leiomyosarcomas (PPLs) are incredibly rare tumors, characterized by an often-aggressive clinical behavior. Diagnosis is frequently incidental. Whenever present, symptoms are nonspecific, thus PPLs are usually misdiagnosed as other more common respiratory diseases or lung cancer subtypes. Surgery is the best treatment choice and in the therapeutic strategy, timeliness and radicality are of major importance. We report the case of a huge left PPL, successfully treated with salvage surgery after a careful multidisciplinary preoperative assessment, which permitted a prompt diagnostic path and surgery.

An asymptomatic giant AB thymoma in a patient with Down syndrome: a case report.

Background: Mediastinal mass management may represent a real challenge for all the physicians who deal with it. Mediastinum, in fact, contains different vital structures which are often involved by growing neoplasms with increasing severity. Therefore, up to 60% of the patients with mediastinal mass are symptomatic, according to the structure involved. Different neoplasms may arise essentially from all mediastinal organs, whereas thymic epithelial tumors and lymphomas represent more than 90% of mediastinal tumors. Case Description: We report the first case described of a giant asymptomatic mediastinal mass in a 43-year-old male affected by Down syndrome (DS), turned out to be a thymoma, treated exclusively and successfully with radical surgery. Despite the absence of any symptoms, the giant thymoma infiltrated the diaphragm, the pericardium, the upper lobe of the left lung together with the left phrenic nerve resulting in the compression of heart and great vessels. Conclusions: To date, this is the first description of a thymic malignancy in a patient with DS, that usually is characterized by a low-incidence of solid tumor except for germ-cells ones. Surgery has been extremely challenging, due the clinical condition of the patient together with the tumor features; nevertheless, oncological radicality criteria were completely fulfilled. After four years from surgery, the patient is alive and still disease-free, highlighting the importance of radical surgery.

Robotic thymectomy: A surgical point of view.

Robotic thymectomy is the most innovative surgical approach for treating disease of the anterior mediastinum. Robotic surgery offers low postoperative morbidity, faster recovery, shorter hospital stay, and better cosmetic results, without compromising surgical radicality. During the operation, the patient is placed in a supine position at the left edge of the operating table with the left hemithorax upward; the position is maintained with sandbags. The target area for the autodocking should be toward the jugulum. The first surgical step is to isolate the inferior thymic horns via the dissection that starts from the inferior portion of the mediastinal tissue and proceeds toward the right side, following the contralateral pleural reflection. Afterward, it is necessary to move toward the superior horns, following the phrenic nerve, the first landmark, to the innominate vein, our second landmark. Finally, we dissect the superior horns while searching for the thymic veins, which could appear atrophic, and clip the vessels to safely isolate the innominate vein. During this step, it is useful to use a retraction movement to progressively dissect the horns from the jugulum. The thymus gland is removed en bloc with the perithymus fat using an endoscopic bag inserted through the right port incision.

Robotic Surgery for Non-Small Cell Lung Cancer Treatment in High-Risk Patients.

Robotic-assisted pulmonary resection has greatly increased over the last few years, yet data on the application of robotic surgery in high-risk patients are still lacking. The objective of this study is to evaluate the perioperative outcomes in ASA III-IV patients who underwent robotic-assisted lung resection for NSCLC. Between January 2010 and December 2017, we retrospectively collected the data of 148 high-risk patients who underwent lung resection for NSCLC via a robotic approach at our institution. For this study, the prediction of operative risk was based on the ASA-PS score, considering patients in ASA III and IV classes as high-risk patients: of the 148 high-risk patients identified, 146 patients were classified as ASA III (44.8%) and two as ASA IV (0.2%). Possible prognostic factors were also analysed. The average hospital stay was 6 days (8-30). Post-operative complications were observed in 87 (58.8%) patients. Patients with moderate/severe COPD developed in 33 (80.5%) cases post-operative complications, while elderly patients in 25 (55%) cases, with a greater incidence of high-grade complications. No difference was observed when comparing the data of obese and non-obese patients. Robotic surgery appears to be associated with satisfying post-operative results in ASA III-IV patients. Both marginal respiratory function and advanced age represent negative prognostic factors. Due to its safety and efficacy, robotic surgery can be considered the treatment of choice in high-risk patients.
