Abstract
PURPOSE Minimally invasive surgery (MIS) for thymic tumors is now accepted widely, in line with improved surgical techniques; however, we occasionally encounter complicated cases of large tumors or of total thymectomy requiring prolonged operative duration or conversion to an open procedure (OP). We reviewed patients registered in a nationwide database to identify the technical feasibility of MIS for thymic epithelial tumors. METHODS Data on patients treated surgically between 2017 and 2019 were extracted from the National Clinical Database of Japan. Clinical factors and operative outcomes were calculated by tumor diameter using trend analyses. Perioperative outcomes of MIS for non-invasive thymoma were investigated using propensity score-matched analyses. RESULTS MIS was performed in 46.2% of the patients. The operative duration and conversion rate increased with the tumor diameter (p < .001). After propensity score-matching, operative duration and postoperative hospital stay were shorter (p < .001), and the transfusion rate was lower (p = .007) in patients who underwent MIS than in those who underwent OP for thymomas ≥ 5 cm. Among patients who underwent total thymectomy, blood loss was less (p < .001) and the postoperative hospital stay was shorter (p < .001) in those who underwent MIS than in those who underwent OP. There were no significant differences in postoperative complications and mortality. CONCLUSIONS MIS is technically feasible even for large non-invasive thymomas or for total thymectomy, although the operative duration and open conversion rate increase with the tumor diameter.

Abstract
INTRODUCTION Thymic epithelial tumors are rare and are classified as thymoma, thymic carcinoma, and thymic neuroendocrine tumors. The objective of this systematic review was to evaluate the treatment options for patients with thymic epithelial tumors. METHODS This systematic review was developed by Ontario Health (Cancer Care Ontario)'s Program in Evidence-Based Care and by the Lung Cancer Disease Site Group. MEDLINE, EMBASE, and the Cochrane Library were searched for studies comparing surgical, radiotherapy, or systemic treatments against any combination of these treatments in patients with thymic epithelial tumors. Meta-analyses were conducted with clinically homogenous studies. RESULTS A total of 106 studies were included, mainly from observational studies. There was an overall survival benefit with postoperative radiotherapy for patients with thymic carcinoma (hazard ratio = 0.65, 95% confidence interval: 0.47-0.89) and for patients with thymoma (hazard ratio = 0.70, 95% confidence interval: 0.59-0.82), especially for those with a high risk for mortality. Patients with thymic carcinoma or thymoma had a response to chemotherapy. Selection bias affected the results for studies that evaluated neoadjuvant chemotherapy or minimally invasive surgical techniques. Furthermore, the overall survival benefit found for adjuvant chemotherapy may have been confounded by the administration of postoperative radiotherapy. CONCLUSIONS For patients with thymoma or thymic carcinoma, the literature is of low quality and subject to bias. There were overall survival benefits with postoperative radiotherapy. The results of this systematic review were used to inform treatment recommendations in a clinical practice guideline. Future large-scale prospective studies that control for confounders are needed.

Abstract
Objective Subxiphoid-subcostal thoracoscopic thymectomy (ST) is an emerging alternative to transthoracic thoracoscopic thymectomy. Potential advantages of ST are the avoidance of intercostal incisions and visualization of both phrenic nerves in their entirety. We describe our experience with ST and compare our results to our previous experience with transthoracic thoracoscopic thymectomy. Methods We conducted an institutional review board-exempt retrospective review of all patients who had a minimally invasive thymectomy from August 2008 to October 2021. We excluded patients with a previous sternotomy or radiological evidence of invasion into major vasculature. The ST approach involved 1 subxiphoid port for initial access, 2 subcostal ports on each side, and carbon dioxide insufflation. We used descriptive and comparative statistics on demographic, operative, and postoperative data. Results We performed ST in 40 patients and transthoracic thoracoscopic thymectomy in 16 patients. The median age was higher in the ST group (58 years vs 34 years; P = .02). Operative data showed no significant differences in operative times, blood loss, or tumor characteristics. In the ST group, we had 2 emergency conversions for bleeding; 1 ministernotomy, and 1 sternotomy. Postoperative data showed that the ST group had fewer days with a chest tube (1 day vs 2.5 days; P = .02). There were no differences in median length of stay, tumor characteristics, final margins, major complication rate, and opioid requirements between the groups. There has been no incidence of diaphragmatic hernia and no phrenic nerve injuries or mortality in either group. Conclusions ST is safe and has similar outcomes compared with transthoracic thoracoscopic thymectomy.

Abstract
Introduction. Thymoma is the most common tumour of the anterior mediastinum. Video-Assisted Thoracic Surgery technique of thymoma resection is spreading world-wide, but the thoracoscopic method is still contentious in many ways. Authors evaluate the early and mid-term results of a 17 years period of VATS unilateral approach at 2 Hungarian thoracic surgical centers. Method. Depending on the anatomical situation of the thymoma, we performed thymectomy, or partial thymectomy (thymomectomy) for the Masaoka–Koga I–II–III stage thymoma from the right or left side through 2 or 3 intercostal ports. We managed the operations with ultrasonic dissector and electrocauter. By using international standards we evaluated perioperative morbidity, mid-term oncological results and clinical symptoms of myasthenia. Results. 23 of the 54 patients were man, 31 were woman, the average age was 58 (26–79) years, 23 of them had myasthenia. The conversion rate was 11,5% (7/61). The average operation time was 84 (39–150) minutes. The average hospitalisation time was 5.5 (3–19) days. The average size of the thymomas was 46 (18–90) mm. The histology resulted thymoma type A in 2 cases, AB in 19 cases, B1/2/3 in 11/11/1 cases, mixed B in 10 cases. The examination of the resection line was R0/1/2 in 42/11/1 cases. The Masaoka–Koga stages were: I (17), IIA (28), IIB (2), III (7). There was 25 thymomectomies, and 29 thymectomies. In seven cases there were extension of the operation to the pericardium (2), to the lung (2), to the phrenic nerve (6), and to innominate vein (1). The in-hospital mortality over 30 day was in 1 case (1.85%). The morbidity was 11/54 (20.4%). The average follow-up time was 62.56 (5–198) months. In the group with myasthenia the effectivity of the operation was 18/21 (85.7%), including complete remission of 5/21 (23.8%). Post-thymectomy myasthenia gravis developed in 2/31 cases (6.5%). The average 5 years survival was 100%, tumour-free 5 years survival was 96%. Conclusions. The higher proportion of the thymomectomy in the early results, higher conversion rate and lower R0 proportion might be in connection with the attitude of the surgeons, with the learning curve and with the limitations of the unilateral method. After a longer follow-up time late results may become more real and comparable. Instead of unilateral VATS technique we have changed to the subxyphoideal approach of VATS because of its better visualisation.

Abstract
Background Thymic epithelial tumors (TETs) are rare, and information regarding their surgical outcomes and prognostic factors has rapidly changed in the past few decades. We analyzed surgical treatment practices for TETs and outcomes in terms of overall survival (OS) and freedom from recurrence (FFR) during a 13-year period in Korea. Methods In total, 1,298 patients with surgically resected TETs between 2000 and 2013 were enrolled retrospectively. OS and FFR were calculated using the Kaplan-Meier method and evaluated with the log-rank test. Prognostic factors for OS and FFR were analyzed with multivariable Cox regression. Results A total of 1,098 patients were diagnosed with thymoma, and 200 patients were diagnosed with thymic carcinoma. Over the study period, the total number of patients with surgically treated TETs and the proportion of patients who underwent minimally invasive thymic surgery (MITS) increased annually. The 5-year and 10-year survival rates of surgically treated TETs were 91.0% and 82.1%, respectively. The 5-year and 10-year recurrence rates were 86.3% and 80.0%, respectively. The outcomes of surgically treated TETs improved over time. Multivariable Cox hazards analysis for OS, age, tumor size, and Masaoka-Koga stage were independent predictors of prognosis. The World Health Organization classification and tumor-node-metastasis (TNM) staging were also related to the prognosis of TETs. Conclusion Surgical treatment of TETs achieved a good prognosis with a recent increase in MITS. The M-K stage was the most important prognostic factor for OS and FFR. The new TNM stage could also be an effective predictor of the outcomes of TETs.

Abstract
Gaurav PatelBackground There are different surgical techniques used for maximal thymectomy. Each technique has its own advantages and disadvantages. We propose a mini sternotomy with pleural preservation approach for complete maximal thymectomy. Methods Over time range of 5 years, 32 patients with diagnosis of thymoma with or without myasthenia gravis (MG) underwent maximal thymectomy by mini sternotomy in our institute. Patient records were examined for the following parameters: age, sex, preoperative medication, symptoms of MG as per Myasthenia Gravis Foundation of America grading system, operating time, duration of postoperative ventilation, length of stay in the intensive care unit, overall length of hospitalization, and postoperative complications. Results The mean age of patients in our study was 43.66. Sex ratio in this study was almost equal. Sixty-nine percent of patients were stage I thymoma according to Masaoka staging. Size of the tumor ranged from 3 to 8 cm with mean size being 4.54 cm. Complete resection with negative tumor margins was possible in all the cases. Four patients had intraoperative pleural injury out of which two patients required intercostal tube insertion. We did not have any serious postoperative complications with no perioperative mortality. Conclusions Mini sternotomy allows maximal removal of thymus through a less invasive approach and is associated with a significantly smoother postoperative course, less overall complications, and good clinical outcome. It is a simple technique that can be performed by any thoracic and surgical oncologists especially in Indian subcontinent where facilities of video-assisted thoracoscopic surgery and robotic video-assisted thoracoscopic surgery are not available in all areas and are expensive.

Abstract
Background: The purpose of this study was to identify the factors which predict the perioperative outcomes after video-assisted thoracoscopic surgery (VATS) thymectomy in patients with myasthenia gravis (MG) or thymic neoplasms Patients and Methods: Data of consecutive patients who had undergone VATS thymectomy in our institution from August 2016 to April 2018 were collected retrospectively from a prospectively maintained database followed by prospective recruitment of patients who underwent VATS thymectomy from April 2018 to February 2020. Results: A total of 31 patients were included. Females were more common (51.6%), and 29 patients (93.5%) had MG. The most common indication for thymectomy was the presence of both MG and thymoma (51.6%). Most MG patients had moderate disease (55.2%) or severe (24.1%) disease preoperatively. Mean operative time and blood loss were 196.9 ± 63.5 min and 122.5 ± 115.3 ml, respectively. Mean hospital stay was 7.9 ± 6.7 days. The rate of major and minor complications was 16.18% and 35.4%, respectively. Multivariate linear regression analysis established that MG symptoms >12 months, prolonged invasive ventilation (intubation ≥24 h), and complications were associated significantly with a prolonged hospital stay. Adjusting for outliers, pre-operative disease severity (MG Foundation of America class), and intubation ≥24 h were the only factors that had a significant impact on perioperative outcomes. Conclusion: Pre-operative disease severity and post-operative invasive ventilation are strong determinants of perioperative outcomes. Pre-operative optimisation and early extubation protocols can further reduce morbidity in patients undergoing thymectomy by the VATS approach.

Abstract
OBJECTIVE To compare long-term outcomes of video-assisted thoracoscopic (VATS) and conventional open surgery in patients with early-stage (Masaoka stage I-II) thymic malignancies. MATERIAL AND METHODS. A Retrospective study included patients after VATS and open thymectomy for the period 2000-2019. Long-term outcomes were analyzed. RESULTS VATS thymectomy was performed in 53 (54.1%) patients, open thymectomy - in 45 (45.9%) cases. Median follow-up period was 66.9 months. Overall 5-year survival was 89.8% and 97% in the Open and VATS groups, respectively (p=0.076). Disease-free survival rates were 79.6% and 86.6% (p=0.279), respectively. There was no significant difference in cumulative incidence of recurrence (13.3% vs 7.5%, p=0.505). Age <50 years and tumor size >5 cm were the independent risk factors of recurrence. CONCLUSION VATS thymectomy is an effective approach ensuring similar long-term outcomes in patients with early stages of thymic malignancies.

Robotic thymectomy for thymoma in patients with myasthenia gravis: neurological and oncological outcomes. Eur J Cardiothorac Surg 2021; 60:890-895. [PMID: 34263301 DOI: 10.1093/ejcts/ezab253] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2020] [Revised: 11/30/2020] [Accepted: 03/22/2021] [Indexed: 01/21/2023] Open
Abstract
OBJECTIVES The goal of this study was to analyse the outcomes in 53 patients with thymoma, 34 of whom had myasthenia gravis (MG), who were treated with robotic surgery. The oncological outcomes of the whole series of patients were analysed. Furthermore, because consistent data are not yet available in the literature, the main focus was the analysis of the neurological results of the patients affected by MG and thymoma. METHODS The clinical outcomes of 53 patients with a diagnosis of thymoma who underwent robotic thymectomy between January 2014 and December 2019 in our institution were collected and evaluated; 34 of these patients had a concomitant diagnosis of MG. The neurological status of the patients was determined from a clinical evaluation according to the Osserman classification and on pre- and post-surgery Myasthenia Gravis Composite scores, whereas neurological clinical outcomes were assessed using the Myasthenia Gravis Foundation of America Post-Intervention Score. Reduction of steroid therapy was also considered. The recurrence rate, adjuvant radiotherapy and overall survival of the patients with a thymoma were evaluated. RESULTS Neurological outcomes: improvement of the clinical conditions was obtained in 26 patients (76.5%) following the operation: complete stable remission was observed in 5 patients (14.7%), pharmacological remission in 10 (29.4%) and minimal manifestation in 11 (32.3%). Four patients (11.8%) exhibited no substantial change from the pretreatment clinical manifestations or reduction in MG medication and 4 (11.8%) patients experienced worsening of clinical conditions. In 21 patients (61.7%) a reduction of the dosage of steroid therapy was obtained. Oncological outcomes: at an average follow-up of 36 months, the overall survival was 96%, 4 patients (7.5%) had pleural relapses and 12 patients (22.6%) underwent postoperative radiotherapy, according to their stage. In accordance with Masaoka staging, 34% were in stage I, 56.6% in stage II and 9.4% in stage III. CONCLUSIONS Our results suggest that robotic surgical treatment of patients with thymoma and concomitant MG is effective in improving the neurological outcomes. Moreover, the oncological results obtained in this series confirm the efficacy of robotic surgery for the treatment of thymic malignancies, with results in line with those of open surgery. However, due to the indolent growth of thymomas, further observations with longer follow-up are necessary.

Abstract
OBJECTIVES To investigate clinical and histopathological characteristics of Vietnamese patients with thymoma and myasthenia gravis (MG), and the outcomes of surgical management using video-assisted thoracoscopic surgery (VATS) thymectomy. METHODS A prospective study was carried out on 61 patients undergoing VATS thymectomy for MG class I, IIA with thymoma in the period from 10/2013 to 5/2019. The WHO histopathological classification, Masaoka's stages and MG grading using the guidelines of the Medical Scientific Advisory Board of the Myasthenia gravis foundation of America (MGFA) were used. All patients were followed up at 1 month, 6 months and over 1 year postoperatively. RESULTS The average patient age was 47.3 ± 10.8 years (21-70). The female/male ratio was 0.91.80.3% of patients had MG class IIA. Most of the patients were at Masaoka's stage I and stage II (75.4%). Only 1 patient (1.7%) had highly malignant type B3 thymoma. Conversion to open surgery was required in 8 patients. The surgical time was 91.8 ± 49.9 min and blood loss was 37.3 ± 31.5 ml. Most patients (68.9%) were extubated in the operating room. The postoperative hospital stay was 9.8 ± 5.9 days (5-37 days). 22.6% of patients relapsed after one-year. Refractory MG declined to 5.7% after surgical treatment. CONCLUSION VATS thymectomy for MG with thymoma was safe and effective, with a lower rate of intraoperative complications, shorter hospitalization, and better long-term outcomes. This approach could be applicable for patients of all age groups with thymomas at early Masaoka's stages.

Abstract
BACKGROUND The long-term outcomes of robotic thymectomy for thymic epithelial tumors (TETs) are not well known, even though the early postoperative outcomes have improved. This study aimed to report the long-term survival and recurrence in patients with TETs who underwent robotic thymectomies. METHODS A total of 158 patients who underwent robotic thymectomy for TET and who were followed-up for more than 1 year were included in the study. The median follow-up time was 43 (interquartile range, 40) months, and 156 (98%) patients were followed completely until the end of the study period. RESULTS The mean age of the patients was 55.7 ± 12.7 years, and the mean size of the tumor was 4.6 ± 2.1 cm. There was no postoperative mortality and postoperative complications occurred in 7 (4.4%) patients. The median length of the postoperative hospital stay was 2 (interquartile range, 1-20) days. Thymoma was the most common cell type (n = 132, 84%), and thymic carcinoma (n = 24, 15%) and neuroendocrine tumors (n = 2, 1%) were the next most common types. Advanced stages more than stage III were identified in 15 patients (stage IIIA: n = 7, 4%; stage IVA: n = 5, 3%; and stage IVB: n = 3, 2%). The 5-year disease-specific survival was 100% in thymoma and 95% in thymic carcinoma. The 5-year recurrence-free survival was 94% in thymoma and 79% in thymic carcinoma. CONCLUSIONS Robotic thymectomy could achieve favorable long-term survival and recurrence rates, comparable to open or thoracoscopic thymectomy.

Abstract
BACKGROUND We compared the clinical outcomes and cost-efficiency of surgical approaches (sternotomy-open, video assisted thoracoscopic surgery, and robotic assisted thoracic surgery) for thymectomy. METHODS This is a retrospective review of 220 consecutive patients who underwent thymectomy between January 1, 2007, and January 31, 2017. Surgical approach was determined by the surgeon, but we only included cases that could be resected using any of the 3 approaches. RESULTS Open approach was used in 69 patients, whereas minimally invasive technique was used in 151 (97, video assisted thoracoscopic surgery; 54, robotic assisted thoracic surgery). Open surgery was associated with greater total hospital cost ($22,847 ± $20,061 vs $14,504 ± $10,845, P < .001). Open group also revealed longer duration of intensive care unit (1.2 ± 2.8 vs 0.2 ± 1.3 days, P < .001) and hospital stay (4.3 ± 4.0 vs 2.0 ± 2.6 days, P < .001). There were no differences in major adverse clinical outcomes. Long-term recurrence-free survival after resection of thymoma was similar between the groups. CONCLUSION Minimally invasive techniques were equally efficacious compared with the open approach in the resection of the thymus. Additionally, their use was associated with decreased hospital duration of stay and reduced cost. Hence the use of minimally invasive approaches should be encouraged in the resection of thymus.

Video-assisted thoracoscopic surgery is safe and reliable for large and invasive primary mediastinal tumors. Wideochir Inne Tech Maloinwazyjne 2020; 16:163-168. [PMID: 33786130 PMCID: PMC7991948 DOI: 10.5114/wiitm.2020.94528] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2020] [Accepted: 03/22/2020] [Indexed: 11/17/2022] Open
Abstract
Introduction Video-assisted thoracoscopic surgery (VATS) was not considered for the treatment of primary mediastinal tumors of large sizes or with local invasion. Aim To investigate the clinical outcomes of VATS for large and invasive mediastinal tumors. Material and methods One hundred and thirteen patients with primary mediastinal tumors were treated by VATS. Twenty-nine patients had bulky tumors (diameter > 6 cm) and 5 patients had invasive tumors. Clinical data were documented and compared. Results No patients suffered from any complications after VATS. No relapse or metastasis occurred in the patients with bulky tumors, while 1 patient with invasive thymoma suffered a relapse after VATS. The 2-year disease-free survival and overall survival in patients with bulky tumors were 100% and 100%, while those in patients with invasive tumors were 75% and 100%. There were no differences in hospital stay after VATS between the patients with bulky tumors and smaller tumors, nor between the patients with invasive tumors and non-invasive tumors. Patients with bulky tumors lost more blood than those with smaller tumors, while more blood loss occurred in patients with invasive tumors than non-invasive tumors. Longer operative time was needed for patients with bulky tumors and invasive tumors. Mediastinal tumors with large size or invasion should not be contraindicated for VATS. The prognosis of such patients treated with VATS was comparable to that of traditional open surgery. Conclusions VATS is a safe and effective procedure for large and invasive mediastinal tumors.

Abstract
Background Approaches of thoracoscopic thymectomy for myasthenia gravis (MG) are debatable. The subxiphoid approach is widely utilized recent years for its better visualization of the anterior mediastinum. In the present study, we compared perioperative outcomes and mid-term effects of the extended thymectomy for MG between the subxiphoid approach and the routine right-thoracic approach. Methods One hundred and thirty-one MG patients treated with thoracoscopic extended thymectomy were analyzed. Among them, 68 patients were operated on via the subxiphoid approach and the other 63 via the conventional right-side unilateral approach. The patient outcomes were retrospectively reviewed and evaluated. Mid-term clinical outcome was assessed according to the classification system proposed by the Myasthenia Gravis Foundation of America (MGFA). Clinical efficacy and variables influencing outcome were evaluated by the Kaplan-Meier method and Cox proportional hazards regression analysis. Results Compared with the right thoracic approach, the duration of the procedure via the subxiphoid approach was significantly shorter (P=0.035), the rates of total thymectomy were higher (P=0.028), and the pain scores on postoperative days 1, 3, and 7 were significantly lower (P<0.001, P<0.001, and P=0.03, respectively). A total of 112 patients with MG were followed up. The subxiphoid approach group reported higher rates of complete stable remission (CSR) and effective treatment of MG, although these differences were not statistically significant (Z=−0.484, P=0.627). By multivariate Cox proportional hazards modes analysis, the chance of CSR was significantly increased when age <40 (OR: 2.623, 95% CI: 1.150–5.983, P=0.022), non-thymomatous MG (OR: 1.078, 95% CI: 1.101–3.316, P=0.021) and MGFA clinical classification (OR: 2.024, 95%:1.164–3.523, P=0.013). Conclusions The subxiphoid approach has shorter operation time, higher rates of total thymectomy and better quality of life compared with the lateral thoracoscopic approach. Preoperative age, pathological diagnoses and MGFA Clinical Classification are the independent risk factors for non-complete stable remission (NCSR) after thymectomy.

Abstract
OBJECTIVE The oncologic efficacy of minimally invasive thymectomy for thymoma is not well characterized. We compared short-term outcomes and overall survival between open and minimally invasive (video-assisted thoracoscopic and robotic) approaches using the National Cancer Data Base. METHODS Perioperative outcomes and survival of patients who underwent open versus minimally invasive thymectomy for clinical stage I to III thymoma from 2010 to 2014 in the National Cancer Data Base were evaluated using multivariable Cox proportional hazards modeling and propensity score-matched analysis. Predictors of minimally invasive use were evaluated using multivariable logistic regression. Outcomes of surgical approach were evaluated using an intent-to-treat analysis. RESULTS Of the 1223 thymectomies that were evaluated, 317 (26%) were performed minimally invasively (141 video-assisted thoracoscopic and 176 robotic). The minimally invasive group had a shorter median length of stay when compared with the open group (3 [2-4] days vs 4 [3-6] days, P < .001). In a propensity score-matched analysis of 185 open and 185 minimally invasive (video-assisted thoracoscopic + robotic) thymectomy, the minimally invasive group continued to have a shorter median length of stay (3 vs 4 days, P < .01) but did not have significant differences in margin positivity (P = .84), 30-day readmission (P = .28), 30-day mortality (P = .60), and 5-year survival (89.4% vs 81.6%, P = .20) when compared with the open group. CONCLUSIONS In this national analysis, minimally invasive thymectomy was associated with shorter length of stay and was not associated with increased margin positivity, perioperative mortality, 30-day readmission rate, or reduced overall survival when compared with open thymectomy.

Abstract
OBJECTIVES Video-assisted thoracoscopic surgery (VATS) has been increasingly used in the management of thymic epithelial tumours. However, its oncological efficacy remains to be proved. The purpose of this study is to compare the oncological outcomes following thoracoscopic versus open surgery in the case-matched groups of patients with early-stage thymic tumours from the Chinese Alliance for Research in Thymomas (ChART) retrospective database. METHODS Between 1994 and 2012, a total of 1087 patients who underwent surgery for UICC (Union for International Cancer Control) pathological Stage I tumours from the ChART retrospective database were recruited for this study. A propensity score-matched analysis was used to compare the long-term outcomes in patients who received VATS or open surgery. RESULTS VATS resection was performed in 271 patients (24.9%) and open surgery in 816 patients (75.1%). Before propensity score matching, the VATS group had a smaller tumour size (P = 0.002), lower grade histology (P = 0.034), lower T stage (P < 0.001) and less adjuvant therapy (P < 0.001). Propensity score matching by gender, myasthenia gravis, tumour size, histological classification, pathological T stage, extent of thymectomy, adjuvant radiotherapy and adjuvant chemotherapy identified 110 patients in each group. After matching, there was no significant difference in patient demographics, tumour characteristics or adjuvant therapy. All matched patients had R0 resection. Overall survival, disease-free survival and cumulative incidence of recurrence were only predicted by WHO histology, but not by surgical approach, in both univariable and multivariable analyses. There was no significant difference in the overall survival (85.7% vs 93.1%, P = 0.539), disease-free survival (92.5% vs 91.9%, P = 0.773), cumulative incidence of recurrence (7.1% vs 5.8%, P = 0.522) and improvement rate of myasthenia gravis (83.3% vs 88.2%, P = 0.589) between the 2 groups. CONCLUSIONS This propensity score-matched study suggests that VATS and open surgeries are associated with similar oncological outcomes for Stage I thymic epithelial tumours. Minimally invasive surgery might be an acceptable surgical approach for early-stage thymic malignancies.

Abstract
Kido and colleagues in 1999 used for the first time the subxiphoid approach. Recently, video-assisted thoracoscopic surgery (VATS) thymectomy has been improved for the advancement of surgical materials and new instruments. The most important aspect regarding the subxiphoid approach is the possibility to avoid the intercostal nerve damage with the consequence of a decreased use of postoperative analgesics, quite short surgical duration, fast discharge from hospital and a guarantee of successful cosmetics results.

Abstract
Background Complete thymectomy is recommended for thymic malignancies to reduce local recurrence and the likelihood of the long-term development of myasthenia gravis (MG). Thymus-conserving surgery (thymomectomy) seems to yield similar results, but evidence is still limited. The objective of this study was to assess if the oncological outcome, in terms of overall survival (OS) and disease-free survival (DFS), are comparable between radical thymectomy vs. conservative thymomectomy patients, and to assess if the outcome of the video-assisted thoracoscopic surgery (VATS) approach was similar to open surgery approach. Methods We retrospectively analyzed 157 consecutive patients with either resectable thymoma or thymic carcinoma from two Italian centers (Humanitas Research Hospital, Milan, and Humanitas Gavazzeni, Bergamo) between 1997 and 2013 who underwent thymomectomy or extended thymectomy with the VATS or open approach; the patients with Miastenia Gravis underwent radical thymectomy. The patients were followed through physical examinations and phone interviews. Results Thymomectomy and thymectomy were performed on 86 (54.8%) and 71 (45.2%) patients, respectively. Prognostic factors and comorbidities were comparable in the two groups. The median follow-up was 77 months. Cox proportional hazards model revealed that Masaoka advanced stage and thymic carcinoma of WHO classification were independent predictive factors for overall survival, but that the extent of surgery and the approach used (minimally invasive versus open) were not. Notably, five- and ten-year survival rates were similar in the two groups. Conclusions In our experience, radical thymectomy and conservative thymomectomy did not differ in terms of disease-free and overall survival rates. In nonmyasthenic patients with early-stage resectable thymic malignancy, minimally invasive thymomectomy provided equivalent results to open thymectomy. Our results should be interpreted with caution due to the retrospective nature of the study. Well-designed, adequately-powered studies should be very welcome to increase the quantity and the quality of clinical evidence before incorporating this procedure in future guidelines.

Abstract
The traditional approach to thymectomy requires median sternotomy based on the assumption that it is the best means to achieve adequate resection margins, complete removal of the thymus and clearance of the anterior mediastinal fat. However, in recent years, VATS thymectomy has been gaining acceptance as a means to achieve adequate oncologic results and symptomatic improvement of myasthenic symptoms with less impact on the patient. We have adopted a flexible approach based on the location of the tumor and on whether the patient has myasthenia gravis (MG) or not when planning minimally invasive VATS thymectomy. A preferential approach from the left side is chosen for clinical stage I-II thymomas located on the left side or on the midline in patients without MG, and a bilateral approach (uniportal VATS on the right side and three-portal VATS on the left side) for MG patients with or without thymoma in order to achieve complete clearance of the anterior mediastinal fat on both sides. Such techniques are herewith clearly illustrated in hope that surgeons wishing to endeavor in such an effort will be facilitated.

Abstract
The robotic system has several technical advantages over the manual video thoracoscopic approach. It offers a high definition three-dimensional view and robotic arms are more comfortable to use, because they allow more precise, flexible, and intuitive movements. This case report describes a locally advanced thymoma in a 75-year-old male patient, excised through a robotic-assisted thymectomy with atypical resection of the infiltrated left upper lobe, the preservation of the left phrenic nerve and partial resection of the left anonymous vein involved, without necessity of reconstruction. Clinical staging was thymoma T3 B1-2, while the postoperative histological classification and radiation was thymoma T3, B3, Masaoka-Koga stage IIB. The postoperative course was uneventful and the patient was discharged in second postoperative day. This case remarks that robotic devices are of great help in the intraoperative recognition and precise management of infiltrated structure, like important vessels and nerves, avoiding conversion to an open approach, which until now was the main surgical indication in these situations.

Abstract
OBJECTIVES Thoracoscopic surgery is widely used for the surgical treatment of thymoma. However, large-sized thymomas are typically treated using open surgery. This study evaluated the feasibility of performing thoracoscopic thymectomy (TT) for thymoma ≥50 mm. METHODS A retrospective review was conducted on 135 patients who underwent TT or open thymectomy (OT) for Masaoka stage I-IVa thymoma between 1996 and 2014. RESULTS Patients were first divided into two groups based on thymoma size: thymoma ≥50 mm and thymoma <50 mm groups. There was no significant difference in the 5-year disease-free survival (DFS) between the groups ( P = 0.5352). Patients in the thymoma ≥50 mm group were further subdivided into TT and OT groups. The length of postoperative hospital stay was significantly shorter in the TT group than in the OT group (5 vs 14 days, P < 0.0001), with significantly fewer postoperative complications (6 patients vs 14 patients, P = 0.0008). There was no significant difference in the 5-year DFS between patients with thymoma ≥50 mm in the TT and OT groups ( P = 0.3501). Finally, patients undergoing TT were further subdivided into thymoma ≥50 mm and thymoma <50 mm groups and, no significant difference in the 5-year DFS was found between these groups ( P = 0.6661). Masaoka stages III-IV, but not thymoma size, were an independent prognostic factor for DFS. CONCLUSIONS These results demonstrate the decreased invasiveness and feasibility of TT for large-sized thymomas.

Abstract
BACKGROUND This study was designed to evaluate the feasibility of video-assisted thoracoscopic surgery (VATS) and to compare the oncologic outcomes of VATS with those of sternotomy in patients with thymoma. METHODS The clinical outcomes of 2,835 patients with thymic epithelial tumors treated between 1991 and 2010 in 32 Japanese institutions were collected retrospectively. The study compared postoperative complications, positive surgical margins, location of recurrence, and survival in 140 of 142 VATS-treated patients (VATS group) matched with 140 of 1,294 sternotomy-treated patients (ST group) by using propensity scores. RESULTS Postoperative complications were observed in 8 patients in the VATS group. The morbidity rate in the VATS group was not different from that of the ST group (p = 0.25). Positive surgical margins were noted in 4 patients (3 in the VATS group; 1 in the ST group). There was no statistically significant difference in the recurrence rate between groups (median follow-up period: 3.7 years in the VATS group; 5.2 years in the ST group). In total the most frequent site of recurrence was pleural dissemination. In the VATS group, the 5-year recurrence-free survival rate was 93.8%, and the 5-year overall survival rate was 97.9%. There was no difference in the recurrence-free survival and overall survival rates between the VATS group and the ST group (p = 0.91 and p = 0.74, respectively). CONCLUSIONS VATS thymectomy was feasible and comparable to sternotomy for the treatment of patients with thymoma with regard to morbidity, incomplete resection rate, and prognosis. However, additional follow-up is required to evaluate long-term outcomes.

Abstract
OBJECTIVE The approach to thymoma resection has usually been determined by tumor size, although established guidelines do not exist. Minimally invasive approaches have been limited to tumors smaller than 5 cm, although 3 cm has been the suggested cutoff for performing an adequate oncologic procedure. No study has compared the perioperative outcomes of patients with 3 cm or larger tumors resected robotically versus sternotomy. METHODS We reviewed patients who underwent resection of 3 cm or larger thymomas from 2004 to 2014. Patients were divided based on approach: robotic and open thymectomy/thymomectomy. RESULTS Forty patients with tumors ranging from 3 to 13 cm were evaluated, 23 robotic and 17 open. Patient and tumor characteristics were similar. An R0 resection was primarily achieved: robotic, 91% (21/23); and open, 88% (15/17); P = 0.832. Adjuvant radiation rates were statistically equivalent: robotic, 17% (4/23) versus open, 41% (7/17); P = 0.191. Major postoperative complications were comparable: robotic, 4% (1/23) versus open, 29% (4/17); P = 0.184. Median chest tube duration was shorter for robotic (1 day) versus open (3 days); P = 0.001. The robotic approach had a shorter median intensive care unit stay compared to open (0 days vs 1 day); P = 0.024. The median hospital stay was shorter for robotic (2 days) versus open (5 days); P < 0.001. CONCLUSIONS In 3 cm or larger thymomas, robotic thymectomy is feasible based on the ability to achieve a complete resection with similar adjuvant radiation therapy rates. Perioperatively, robotic thymectomy is associated with lower morbidity; and shorter chest tube duration, intensive care unit stay, and hospital stay compared to open. However, oncologic outcomes are immature and require prolonged surveillance.

Abstract
Thymoma remains the most common primary anterior mediastinal neoplasm. Surgical resection remains central to the treatment of thymoma, with thoracoscopic thymectomy (TT) being increasingly performed. This present review article aimed to summarize current studies comparing TT and open thymectomy (OT). Recently, most patients with Masaoka stage I-II thymoma have been receiving TT. This procedure is associated with a significantly shorter post-operative hospital stay, decreased intraoperative blood loss, and fewer complications compared with OT. Recurrence rates of thymoma after TT range from 0% to 6.7%, and the 5-year disease-free survival (DFS) ranges from 83.3% to 96%. The oncological outcomes of TT are comparable to that of OT. Masaoka stage and the World Health Organization (WHO) type classification are valuable predictors of the prognosis of thymoma; hence, the optimal treatment for thymoma should be performed according to these two. TT is less invasive, with equivalent oncological outcomes, when compared with the OT. Minimally invasive surgery including TT for stage I-II thymomas is becoming the mainstay of therapy.

Abstract
Complete resection is the standard of care for treatment of thymic malignancies. The use of minimally invasive surgery remains controversial. We searched online databases and identified studies from 1995 to 2014 that compared minimally invasive to open thymectomy for thymic malignancies. Study end points included operative blood loss, operative time, respiratory complications, cardiac complications, length of hospital stay, R0 resection, and recurrence. We summarized outcomes across studies using random-effects meta-analysis to account for study heterogeneity. We calculated ORs for binary outcomes and standardized mean differences for continuous outcomes. We calculated incidence rate ratios for the number of recurrences, accounting for total person-time observed in each study. Of 516 potential reference studies, 30 with a total of 2038 patients met the inclusion criteria. Patients with Masaoka stage I or II thymic malignancy constituted 94.89% of those in the minimally invasive surgery (MIS) group and 78.62% of those in open thymectomy (open) group. Mean tumor size was 4.09 cm (MIS) versus 4.80 (open). Of the 1355 MIS cases, 32 were converted to open cases. Patients in the MIS group had significantly less blood loss; however, no significant differences in operating time, respiratory complications, cardiac complications, or overall complications were identified. Length of stay was shorter for patients in the MIS group. When patients with Masaoka stage I and II thymic malignancy only were analyzed, there was no difference in rate of R0 resection or overall recurrence rate. One postoperative death occurred in the open group. The results of this unadjusted meta-analysis of published reports comparing minimally invasive with open thymectomy suggest that in selected patients with thymic malignancy, minimally invasive thymectomy is safe and can achieve oncologic outcomes similar to those of open thymectomy.

Abstract
Video-assisted thoracoscopic surgery (VATS) has revolutionized the practice of thoracic surgeons and improved patient experiences and outcomes worldwide. The VATS approach has matured over the past decades and now accounts for approximately 50 % of all operations in specialized thoracic surgery units. The VATS procedure is less invasive and therefore allows a faster recovery of patients. Over the last 20 years VATS has developed into a safe and effective technique for the diagnostics and therapy of many thoracic diseases. With increasing experience thoracic surgeons can carry out more advanced and technically challenging interventions. Nowadays, VATS is the superior technique in many cases of thoracotomy.

Abstract
The aim of the present study was to examine the feasibility and efficacy of thoracoscopic radical resection of large retrosternal thymoma using artificial pneumothorax. A retrospective analysis was performed on 19 patients with bulky thymoma who underwent thoracoscopic resection using artificial pneumothorax by CO2 insufflation. The operations were performed with unilateral or bilateral thoracic incisions via single lumen endotracheal intubation and two-lung ventilation. This approach provided excellent exposure of the thoracic cavity and reliable control of the neuro-vascular structures in the anterior mediastinum, which was of vital importance for the extended resection of malignant thymoma. The operation time was 140.0±51.4 min without conversion to thoracotomy or sternotomy. The pathological diagnosis was confirmed by immunohistochemistry, including 5 cases of thymus lipomyoma, 1 case of thymus hyperplasia, 1 case of thymus cyst, 2 cases of type AB thymoma, 4 cases of type B1 thymoma, 4 cases of type B3 thymoma, and 2 cases of thymic carcinoma. Furthermore, there were no complications such as recurrent laryngeal nerve injury, phrenic nerve injury, pulmonary infection or atelectasis, with a hospital stay of 5.0±3.0 days. In conclusion, the thoracoscopic resection of thymoma using artificial pneumothorax is a preferable approach, that may be considered for patients with bulky retrosternal tumors.

Abstract
BACKGROUND Some studies compared the safety and efficacy of thoracoscopic thymectomy (OT) with open thymectomy (TT) in the treatment of thymoma, but the results remained controversial. This meta-analysis was designed to determine the safety and efficacy of thoracoscopic thymectomy in comparison with open thymectomy in the treatment of thymoma. METHODS Relevant studies were searched in databases of PubMed, EMBASE and Web of Science. Comparative studies of thoracoscopic thymectomy and open thymectomy in the treatment of thymoma were included. Both short-term perioperative and long-term oncologic outcomes were analyzed. RESULTS 14 Eligible studies were identified through electronic databases. Our analysis suggested, when compared with open thymectomy, patients having thoracoscopy might benefit from less blood loss (p = 0.004), lower blood transfusion rate (p = 0.02), shorter mean duration of chest tube (p = 0.002), hospital stay (p < 0.001) and lower complication (p = 0.03). There was no statistical difference in 5-year OS rate (p = 0.14) and DFS/RFS rate (p = 0.07) between two groups. CONCLUSION Our study indicated that thoracoscopic thymectomy could become a valid alternative to open thymectomy in selected patients with thymoma.

Abstract
BACKGROUND Video-assisted thoracoscopic surgery (VATS) has been applied to resection of small and well-encapsulated thymomas. However, few data are available regarding to the application of VATS in stage III thymomas. METHODS A novel subxiphoid and subcostal arch approach for thoracoscopic extended thymectomy was developed by us. From January 2014 to August 2015, 14 patients with stage III thymoma were treated by using this new technique in the Department of Thoracic Surgery, Tangdu hospital, Xi'an, China. These patients were retrospectively reviewed and analyzed. RESULTS Among the 14 patients, 1 patient was converted to transsternal approach owning to invasion of the superior vena cava. The other 13 patients with thymomas invading the pericardium, lung tissues and left innominate vein (LIV), were successfully operated on by using this new technique. The average operation time was 120.0±32.7 min (80-170 min), the average volume of estimated blood loss was 51.5±44.8 min (10-150 mL) and the average postoperative hospital stay was 4.8±1.5 days (3-9 days). There was no perioperative death. Two patients suffered postoperative complications including one patient with atrial fibrillation (AF) and the other one with myasthenic crisis (MC). The postoperative pain score decreased dramatically from 3.8±1.0 [3-6] at 24 hours to 1.5±0.9 [0-6] at 48 hours, and finally to 0 at 3 months after surgery (P=0.000). The patients reported a higher cosmetic score of 92.6±2.7 [90-96]. There was no tumor recurrence and the five patients with myasthenia gravis had improvement and did not need any medication until follow-up. CONCLUSIONS Based on our limited experience, the subxiphoid and subcostal arch thoracoscopic extended thymectomy is safe and feasible for selective stage III thymoma, and might reduce the postoperative pain and provide satisfied cosmetic effect.

Abstract
BACKGROUND Thymectomy is the mainstay of treatment for thymoma and other anterior mediastinal tumors, and is often utilized in the management of patients with myasthenia gravis (MG). While traditionally approached through a median sternotomy, minimally invasive approaches to thymectomy have increasingly emerged. The present systematic review was conducted to compare perioperative and clinical outcomes following minimally invasive thymectomy (MIT) and open thymectomy (OT). METHODS Articles were obtained through a PubMed literature search. Comparative studies reporting clinical outcomes following MIT and OT were eligible for inclusion. We selected studies with full text availability, written in the English language, published after 2005 and with at least 15 patients in each arm. A descriptive analysis was performed. RESULTS Twenty studies were included, involving a total of 2,068 patients undergoing either MIT (n=838) or OT (n=1,230). Within individual studies, MIT and OT cohorts were well matched with regards to patient age and gender, but there was considerable variation across studies. Resected thymomas were consistently larger in OT groups, with mean diameter significantly larger in five studies (MIT, 29-52 mm; OT, 31-77 mm). MIT was consistently associated with a lower estimated blood loss (MIT, 20-200 mL; OT, 86-466 mL), chest tube duration (MIT, 1.3-4.1 days; OT, 2.4-5.3 days), and hospital length of stay (MIT, 1-10.6 days; OT, 4-14.6 days). There were no consistent differences in rates of perioperative complications, thymoma recurrence, MG complete stable remission, or 5-year survival. CONCLUSIONS In appropriately selected patients, MIT may reduce blood loss, chest tube duration, and hospital length of stay, with comparable clinical outcomes compared to OT via median sternotomy.

Abstract
In the past, mediastinal surgery was associated with the necessity of a maximum exposure, which was accomplished through various approaches. In the early 1990s, many surgical fields, including thoracic surgery, observed the development of minimally invasive techniques. These included video-assisted thoracic surgery (VATS), which confers clear advantages over an open approach, such as less trauma, short hospital stay, increased cosmetic results and preservation of lung function. However, VATS is associated with several disadvantages. For this reason, it is not routinely performed for resection of mediastinal mass lesions, especially those located in the anterior mediastinum, a tiny and remote space that contains vital structures at risk of injury. Robotic systems can overcome the limits of VATS, offering three-dimensional (3D) vision and wristed instrumentations, and are being increasingly used. With regards to thymectomy for myasthenia gravis (MG), unilateral and bilateral VATS approaches have demonstrated good long-term neurologic results with low complication rates. Nevertheless, some authors still advocate the necessity of maximum exposure, especially when considering the distribution of normal and ectopic thymic tissue. In recent studies, the robotic approach has shown to provide similar neurological outcomes when compared to transsternal and VATS approaches, and is associated with a low morbidity. Importantly, through a unilateral robotic technique, it is possible to dissect and remove at least the same amount of mediastinal fat tissue. Preliminary results on early-stage thymomatous disease indicated that minimally invasive approaches are safe and feasible, with a low rate of pleural recurrence, underlining the necessity of a "no-touch" technique. However, especially for thymomatous disease characterized by an indolent nature, further studies with long follow-up period are necessary in order to assess oncologic and neurologic results through minimally invasive approaches. Furthermore, increased robotic experience and studies, including randomized controlled trials, are needed to validate the findings of the current literature.

Abstract
A wide range of technical approaches for the minimally invasive resection of thymus have been described. Most of the time, the benefits are superior cosmetic outcome and shorter duration of postoperative stay. Other demonstrable differences that have been reported include shorter duration of surgery, less intraoperative blood loss and less postoperative pleural drainage. Robotic surgery and video-assisted surgery (VATS) may become routinely used procedures in the treatment of stage I and II thymomas.

Abstract
BACKGROUND Video-assisted thoracoscopic surgery (VATS) thymectomy is an increasingly utilized alternative to traditional open approaches for the resection of thymomas. Recent studies have suggested comparable survival and oncological efficacy as well as reduced perioperative morbidity when using the VATS approach. This current systematic review thus aimed to critically evaluate existing evidence for the efficacy and safety of VATS versus open (transsternal or transthoracic) thymectomy for thymomas. METHODS Six electronic databases were searched from their date of inception to April 2015. Relevant studies were identified using specific eligibility criteria and data were extracted and analyzed based on predefined primary and secondary endpoints. RESULTS Fourteen comparative observational studies with a total of 1,061 patients were obtained for qualitative assessment, data extraction and analysis. Five-year overall survival and 10-year recurrence-free survival was similar or higher in patients undergoing VATS compared to open thymectomy. On average, the VATS group also demonstrated reduced intraoperative blood loss (131.8 vs. 340.5 mL), shorter hospital stays (7.0 vs. 9.8 days), and lower rates of postoperative pneumonia (1.9% vs. 4.1%). The mean rate of conversion from VATS to open thymectomy was relatively low (3.1%), while 30-day mortality remained low in both the VATS and open groups (0 vs. 0.3%). CONCLUSIONS The current evidence suggests that VATS thymectomy for thymoma has at least equal if not superior oncological efficacy and survival outcomes, as well as reduced perioperative complications, compared to open surgery. Further adequately powered studies and future randomized trials are required to confirm these findings.

Abstract
Minimally invasive surgery has changed the way operative procedures are performed in many specialties. As surgeons have become progressively facile with these techniques, the opportunities to use them have expanded. In thoracic surgery, many surgeons now use minimally invasive techniques to resect small, uncomplicated pathologies of the mediastinum as well as to perform thymectomy for myasthenia gravis. Experience with these techniques has allowed new knowledge to be gained and expansion of the use of these techniques for more complicated mediastinal pathology. This keynote address will outline the instrumentation and techniques that we have adopted over a decade of using these techniques for more complicated mediastinal pathology.

Abstract
INTRODUCTION The objective of this study was to evaluate the feasibility of thoracoscopic thymectomy (TT) for treatment of early-stage thymoma and to compare the outcomes with those after open thymectomy (OT). METHODS A retrospective review of 98 patients who underwent TT or OT of Masaoka stage I-II thymoma without thymic cancer between 1996 and 2013 was performed. RESULTS Thoracoscopic thymectomy was performed in 67 patients, and OT was performed in 31 patients. The intraoperative blood loss amounts differed significantly between the TT group and OT group (100 vs 185 mL, P = 0.0070). The postoperative hospital stay was significantly shorter in the TT group than in the OT group (4 vs 12 days, P < 0.0001). No patient in the TT group underwent conversion to open surgery, and no surgical complications, such as massive bleeding, were observed. Two patients experienced recurrence in the TT group during the median postoperative follow-up period of 65 months. No significant differences were found in the 5-year disease-free survival rates between the two groups. There were no significant differences in disease-free survival as classified by Masaoka stage, World Health Organization type, and the extent of resection of the thymus. CONCLUSION Our outcome showed that TT largely reduced the degree of invasiveness. The outcome was not inferior to that of OT. The results primarily demonstrated the feasibility of TT for treatment of early-stage thymoma.

Abstract
BACKGROUND Tumors of the mediastinum as well as normal thymus glands in patients with myasthenia gravis have traditionally been resected using large and morbid incisions. However, robotic-assisted mediastinal resections are gaining popularity because of the many advantages that the robot provides. However, few comprehensive reviews of the literature on robotic-assisted mediastinal resections exist. METHODS A systemic review of the current medical literature was performed, excluding cases related to esophageal pathology. These studies were evaluated and their findings are reported in this comprehensive review. Approximately 48 papers met the inclusion criteria for review. RESULTS Robotic-assisted surgical systems are increasingly being used in mediastinal resections. Based on the available literature, robotic-assisted thoracoscopic surgery in the mediastinum is feasible and safe. Robotic-assisted mediastinal surgery appears to be superior to open approaches of the mediastinum and is comparable with videothoracoscopic surgery when patient outcomes are considered. CONCLUSIONS Increased robotic experience and more studies, including randomized controlled trials, are needed to validate the findings of the current literature.
