Annual report of Department of Thoracic Surgery at Shanghai Chest Hospital
Introduction
The Department of Thoracic Surgery in Shanghai Chest Hospital is the largest thoracic center in China with the most complete spectrum of diseases and disorders. In recognition of the departmental skill and expertise, it is considered a national key clinical discipline. Along those lines, and in order to further improve outcomes, the Thoracic Surgery Department was one of the earliest departments in China to carry out standardized surgery treatment for thoracic cancer. The Department was awarded second place in the list of national best specialists in 2014, 2015 and 2016 consecutively. The amount of thoracic surgery has exceeded 10,000 cases since 2016 (Figure 1) and peri-operative mortality of thoracic surgery was extremely low: 0.09% in 2016 and 0.08% in 2017 (Figure 2).
In a move to further improve outcomes, since June 2015 the Department of Thoracic Surgery at Shanghai Chest Hospital has been evolving into several thoracic sub-specialties, including lung, esophagus, mediastinum, trachea, and transplantation. The Department of Esophageal Surgery has formed distinctive clinical programs, containing minimally invasive surgical treatment, complex esophageal surgery, endoscopic interventional therapy and one-stop multi-disciplinary service. The annual operational cases of mediastinal surgery are increasing, especially for thymic surgery, where Shanghai Chest has the highest case volume in the world. In keeping with international trends, and leading the way in China, the proportion of minimally invasive surgery continues to increase within our department. New technologies continue to develop, and the success of minimally invasive preoperative diagnosis is improving. The field of advanced tracheal surgery continues to grow with more than 50 tracheal disease patients admitted each year to Shanghai Chest.
Section of Lung Surgery
High-volume center for lung surgery
The Department of Thoracic Surgery offers a full range of services including traditional open surgery, muscle sparing minimally invasive surgery, video-assisted and robotic-assisted thoracoscopic surgery (VATS and RATS) involving the lungs, esophagus, chest wall and the mediastinum. In recent years, benign and malignant pulmonary diseases have been increasing dramatically across China and are now accounting for the majority proportion of general thoracic surgeries at the Shanghai Chest Hospital. From 2009 to 2017, we performed a cumulative 60,321 cases of major thoracic surgical procedures, including 43,528 (72.2%) patients with lung carcinomas (Figure 3).
Highly experienced in management of complex pulmonary diseases
The Section of Lung Surgery has hosted numerous milestones in its history, from pioneering lung transplantation in 2003 to applying RATS and VATS system for sleeve resection and pneumonectomy in 2000s.
For the past 60 years, patients from all over China have been coming to the Shanghai Chest Hospital for surgical care. As an esteemed referral center for complex chest conditions in China, the Department of Thoracic Surgery has extensive experience across the full spectrum of general thoracic surgical procedures. From 2009 to 2017, Section of Lung Surgery completed 34 cases of lung transplantation, 787 cases of sleeve lobectomy, 3,178 cases of segmentectomy and 617 cases of pneumonectomy (Figures 4-8).
Minimally invasive thoracic surgery
Shanghai Chest Hospital surgical team constantly strive to investigate and incorporate the latest techniques in minimally invasive surgery, from muscle sparing thoracotomy to VATS and RATS, for management of pulmonary diseases. Among the 43,528 lung carcinoma resections in the past 9 years, 33,952 (78%) were fulfilled by VATS resection and 1,306 (3%) by robot (Figures 9,10). In 2015, the first robot-assisted sleeve lobectomy for lung cancer in China was successfully completed here. To date, 23 patients with complex centrally located lung cancer have received this minimal invasive procedure.
Our mission
Our mission is to offer outstanding surgical care with an individualized approach. By utilizing the state-of-the-art facilities and technology, such as VATS and robotic systems, we will never cease in our goal to deliver the most up-to-date surgical techniques and care available in the world. We are also committed to improve the standard of care through cutting-edge clinical studies and translational research and state of the art medical and surgical education.
Section of Esophageal Surgery
A total of 792 cases of esophageal resections were completed in 2017. With the increasing number of early stage esophageal cancer being detected, the goal of an “all in one” endoscopy—thoracoscopy and laparoscopy—robot platform to manage these patients was established. The goal was to offer minimally invasive approaches to carry out individualized surgical treatment for our patients. For early superficial lesions, endoscopic diagnosis, staging, and resection have become the standard of care at Shanghai Chest. For locally advanced disease, minimally invasive surgery represented by total thoracoscopic-laparoscopic esophagectomy has been increasing rapidly in the past few years and has gradually become the mainstay of all resections. Now its use has been extended into patients with locally advanced diseases after successful induction therapies prior to surgery. With the addition of robot-assisted minimally invasive esophagectomy, we have brought the most advanced technology for esophageal cancer resection in the world to Shanghai Chest and its patients. After successfully completed the first case of robot-assisted esophagectomy in China in 2010, Shanghai Chest Hospital has completed the largest number of these procedures in China. In total, 132 cases were accomplished in 2017 (Figures 11,12).
As one of the top-level service providers in China, the esophageal surgery division strives to provide individualized management of complex and difficult disease with extensive group experience, multi-disciplinary teams, and outstanding surgical and endoscopic techniques. Examples of innovations include the use of free jejunal interposition for benign cervical strictures of the esophagus in the attempt to preserve normal anatomy and function of the digestive tract, use of colon replacement/interposition for patients with cervical esophageal cancer and/or previous history of gastric surgery, and salvage esophagectomy for recurrent or persistent disease after definitive chemoradiotherapy (Figures 13,14).
As the leading unit in Jiao Tong University Clinical Center for Esophageal Diseases, a multidisciplinary team (MDT) for diagnosis and treatment of esophageal cancer was established in 2010. A team uniting members of surgery, radiotherapy, medical oncology, radiology, pathology, endoscopy, and nursing care, the MDT discussion takes place at regular intervals, providing individualized and standardized therapeutic strategy for esophageal cancer patients.
For patients with locally advanced disease, neoadjuvant therapy including chemotherapy and concurrent chemoradiation are delivered to increase the radical resection rate and to improve long-term outcomes. Clinical trials are also ongoing to investigate the safety and effectiveness of various adjuvant therapies after surgery. These include a multi-center phase III trial of adjuvant therapies or surgery alone for high-risk pN0 esophageal cancer (NCT02891083), and comparison of robot-assisted minimally invasive esophagectomy versus open surgery in patients with locally advanced esophageal cancer after neoadjuvant chemoradiotherapy (17411971200), comparative of robot assisted minimally invasive esophagectomy and thoracoscopic-laparoscopic esophagectomy for esophageal cancer.
Section of Mediastinum Surgery
Numerous benign or malignant disorders occur within the mediastinum, including conditions pertinent to the primary structures, diseases extending from neighboring organs, or lesions manifesting systemic changes of the body. Figure 15 highlights the development of mediastinum surgery in Shanghai Chest hospital over the last decade. The total number of major procedures completed during 2008 to 2017 in mediastinal surgery has reached 5,449 cases. Minimally invasive surgical techniques, such as VATS and robotic surgery have been increasing very rapidly, along with a decrease in open procedures in recent years. In the Shanghai Chest surgical database, the number of minimally invasive procedures had exceeded open procedure since 2014. In 2017, VATS and robotic procedure were performed in 567 and 93 patients, which accounted for 60.6% and 9.9% of the total number of annual cases respectively. In addition to benign lesions and early stage malignancies, minimally invasive surgery has been increasingly applied in patients with locally advanced diseases even after induction therapies, as well as those with recurrent diseases. This has led to better patient recovery and improved quality of life and functional status after surgery.
Locally advanced mediastinum tumor patients with complicated surgery (including vascular reconstruction or replacement, partial cardiac resection, lobectomy, giant mediastinal tumor resection, etc.) continue to increase (Figures 16,17).
Among the 936 mediastinal lesions resected in 2017, there were 402 thymic epithelial tumors, followed by 275 cysts, 92 neurogenic tumors, 72 germ cell tumors, and 53 lymphatic tumors (Figure 18).
Histological analysis revealed 276 thymomas (19 of type A, 114 of type AB, 45 of type B1, 54 of type B2, 35 of type B3, 6 of micronodular thymoma, 3 of metaplastic thymoma), 85 thymic carcinomas, 31 neuroendocrine thymic tumors (NETT) and 10 unknown types (Figure 19).
Thanks to the joint effort from an outstanding multi-disciplinary team, comprehensive and evidence-based multi-modality approach has helped our patients with advanced mediastinal tumors. By employing induction chemoradiation, extensive surgical procedures such as superior vena cava bypass and pleurectomy together with intrapleural thermo-chemotherapy, and hemi-thorax pleural irradiation, a satisfactory control rate has been achieved in stage III–IV thymic diseases.
Section of Tracheal Surgery
Shanghai Chest Hospital is the leading center for tracheal surgery in China and a constant innovator in this challenging area (Figure 20). Total number of trachea and bronchial surgery cases was 51 in 2017. These included trachea surgeries in 40 cases, main bronchial surgery in six cases, and carina resection and reconstruction in five cases.
The disease spectrum included benign and malignant lesions in the trachea, main bronchus, and at the carina, with the majority of cases being malignant tumors. Among the tracheal and main bronchial malignancies, the most common types are adenoid cystic carcinoma (21 cases) and squamous cell carcinoma (ten cases). The other nine cases of primary malignant tumors were mucinous adenocarcinoma, adenosquamous carcinoma, small cell carcinoma, leiomyosarcoma, myoepithelioma, epithelial-myoepithelial carcinoma, mucosa-associated lymphoid tissue (MALT) lymphoma, lymphoepithelioma-like carcinoma, and metastatic thyroid papillary carcinoma. In 11 cases the lesion was benign, including airway stenosis after trauma, leiomyoma, and mucous gland adenoma (Figure 21).
Airway resection and reconstruction is an extremely complicated surgery and requires the ability to use multiple different surgical approaches. Individualized surgical approach for optimal exposure is therefore critically important for such procedures. Based on the imaging studies and bronchoscopy examination, right posterolateral thoracotomy was adopted in 19 cases, including four complex reconstructions in patients with tumor invading the carina. Cervical incision was used in 21 cases. Addition of partial sternotomy was required in 11 cases to ensure radical resection and successful reconstruction (Figure 22). In two patients with difficult airway because of nearly complete tumor blockage of the tracheal lumen, extracorporeal circulation was introduced so as to assure the safety of surgery.

Education
This Department has eight PhD candidates and four master’s candidates of medicine college at Shanghai Jiao Tong University.
Training programme
As one of the largest and top thoracic and cardiovascular surgery training centers in China, our programs has enrolled a total of 69 thoracic surgeons from all regions of China this year, including 37 trainees in the 45th National Cardiothoracic Surgery Training Program.
Discussion
Starting with 2017 data, the Department of Thoracic Surgery in Shanghai Chest Hospital will publish an annual performance report every year. This will not only enable our peers to obtain the medical quality information and case volume of our team but will also serve as an internal reminder to constantly improve the efficiency and quality of the medical services we provided. Through the exchange and cooperation with domestic and foreign counterparts, we will continue to push Shanghai Chest to be one of the best clinical centers for comprehensive thoracic surgery in the world.
In the next year, we will strive to improve the quantity and quality of surgery. We wish to expand the indication of minimally invasive surgery through combining the mature minimally invasive techniques with more complex surgery. Continuously more innovative techniques will be incorporated into our program via ongoing education and collaboration within our institution, colleagues in China, and colleagues around the world. Our department will initiate and participate in more single center and multi-centered clinical trials and get actively involved in the development or modification of treatment guidelines for thoracic surgery.
