Title: Treatment of Hepatocellular Carcinoma: Perspectives from the East and West

Symposium English Publicly seek/partial designation	1.Evaluation of neoadjuvant therapy for esophageal cancer and postoperative treatment option Englishdetail For resectable advanced esophageal cancer, neoadjuvant chemotherapy using 5-fluorouracil and cisplatin is the standard therapy in Japan. A clinical trial (JCOG1109) is currently under way to determine the effect of more powerful chemotherapy or chemoradiotherapy. Recently, several reports demonstrated the effectiveness of a new regimen (5-fluorouracil, cisplatin and Docetaxel). On the other hand, some cases fail to show tumor reduction in spite of neoadjuvant therapy. Adequate timing and methods to evaluate clinical response, and suggestions for treatment option for those who fail to respond are to be discussed. 2.Treatment strategies for gastric cancer in the era of molecular targeting therapy Englishdetail In addition to the existing treatment with cytotoxic anticancer agents, the usefulness of a HER2-blocking antibody trastuzumab for advanced gastric cancer has been demostrated, followed by an anti-VEGF agent ramucirumab. Thus in Japan, both trastuzumab and ramucirumab are now included in the the guideline as the standard treatment. With the introduction of nivolumab, an antiPD-1 antibody, anticancer treatment of gastric cancer is also extending into a new era. In this symposium, the approaches and treatment outcomes are to be discussed to identify optimal treatment strategy using molecular targeting agents for advanced gastric cancer. 3.Surgical techniques for advanced transverse colon cancer Englishdetail The operative techniques for transverse colon cancer have not been standardized. Mobilization of hepatic or splenic flexures is difficult because of the complexity and variety of surgical anatomy around the transverse colon. Furthermore, venous branches that drain into the surgical trunk are highly variable anatomically. The techniques and strategy to perform safe transverse colectomy are to be discussedl. 4.Conversion surgery for unresectable pancreatic cancer Englishdetail Despite advances in diagnostic modalities, the majority of pancreatic cancer are metastatic or locally advanced at the time of diagnosis. In recent years, more promising regimens such as FOLFIRINOX and Gem/nab PTX as compared with conventional chemotherapeutic regimens have been introduced and reported to improve outcomes by allowing conversion surgery for initially unresectable pancreatic cancer. However, recommended regimens including chemoradiotherapy, treatment duration, criteria for resectability and role of adjuvant therapy are yet to be clarified. In this symposium, multidisciplinary teams are to address treatment strategy and results of conversion surgery for initially unresectable pancreatic cancer. 5.Social contribution as a gastroenterological surgeon detail The medical care of our country is characterized by a medical service under national health insurance, but the contribution to society with the medical care such as medical support overseas or the correspondence at the time of the natural disaster is not necessarily seized with the limit of health insurance. At this symposium, please shows the contribution to society that a digestive surgeon practices it or can be possible concretely, and give us hints for a digestive surgeon to more contribute to the society in future. 6.Oncologic emergencies associated with gastroenterological surgery Englishdetail Oncologic emergencies in the field of gastroenterological surgery include various clinical conditions for which an urgent intervention is needed for 'hemorrhage', 'perforation', 'obstruction' and 'infection' as a result of cancer. Surgical decision making for such emergencies requires careful decision making by balancing between the resectability, curability and timing for intevention to save a life. In this symposium, different strategies amongst individual institutions in dealing with such emergencies are to be discussed. 7.The utilization of 'Big Data' in gastroenterological surgery Englishdetail By the enforcement of Basic Act on the Advancement of Public and Private Sector Data Utilization, amendment of Act on Protection of Personal Information, spread of digitization and the advancement of information network and widespread use of smartphones, the public and private sectors are enhancing the utilization of 'Big Data' in the industrial circles. In the field of surgery, accumulation of 'Big Data' by the National Clinical Database or national cancer registry led by each academic society have been carried out. In this symposium, the use of 'Big Data' at advanced instituitons will be discussed. 8.Reality of cancer treatment and employment detail In recent years, one out of two Japanese develop, and one out of three die of cancer. Early diagnosis through medical examination and inproved treatments contribute to improved survival in cancer patients, and a new era of 'living with cancer' has arrived. While cancer patients are engaged in various types of occupation and work, employers' approaches to employees with cancer are variable. Employment for patients is not only economical means to finance households and treatment costs, but also a spiritual self-support to live with satisfaction and dignity. However, cancer patients usually need to reduce their work-load which is often associated with reduced income, and a fine balance between treatment and work becomes difficult to maintain. Therefore, cancer patients suffer from various types of anxiety. The challenges of cancer patients for treatment and employment are expected from various viewpoints.

Video Symposium English Publicly seek/partial designation	1.Advances in surgical techniques for endoscopic surgery for esophageal cancer Englishdetail Advances of surgical technique in endoscopic esophageal cancer surgery including mediastinoscopy has become popular rapidly nationwide in the past ten years. While endoscopic surgery is superior due to minimally invasiveness, cosmetic, and highly precise surgery by magnified visual effect, it is inferior to indirect vison with tactile sense and restriction of manipulation. Recently, to dispel this concern progress in image and devices have been contributed for the spread of 3 dimension image and robotic surgery. We would like to discuss what the esophageal endoscopic surgery aims and develops for the next 10 to 20 years based on current situation. 2.Advances in techniques for laparoscopic gastric surgery Englishdetail Since the first laparoscopic distal gastrectomy for gastric cancer in 1991, Japan is leading other countries in varous types of laparoscopic procedures for gastric cancer, such as laparoscopic total gastrectomy and proximal gastrectomy. Verification of laparoscopic gastrectomy for advanced gastric cancer and the cancer in the upper stomach have been carried out, and robotic-assisted gastrectomy has recently been adpoted by the national insurance system in Japan. Advances in laparoscopic surgical procedures are not limited to gastric cancer, and adopted in obesity and metabolic surgery. In this video session, progress in the field of gastric surgery is to be demonstrated and discussed. 3.Advances in techniques for laparoscopic colorectal surgery Englishdetail Laparoscopic surgery for colorectal cancer is increasing, for which short- and long-term results are to be clarified soon. On the other hands, the number of surgical procedures for IBD is not decreasing in spite of the advances in drug therapy. In this video session, new techniques or instruments for laparoscopic colorectal surgery, such as TaTME or navigation surgery using near-infrared spectroscopy (NIRS) are to be presented and the future of laparoscopic colorecal surgery will be discssed. 4.Surgical procedures for advanced or recurrent rectal cancer Englishdetail Surgery for locally advanced or recurrent rectal cancer remains controversial because of the difficulty to balance between curability and maintenance of functions. However, in spite of multidisciplinary approach, complete surgical resection (R0), such as TPE or concomitant resection of the sacrum remains the only hope for cure. However, such invasive procedures are often associated with rectal or bladder dysfunction, and optimal treatment is yet to be developed. In this video session, surgical indications, patient selection, techniques, and knack and pitfalls of the operation for locally progressive or recurrent rectal cancer will be discussed. 5.Advances in surgical procedures for hepatobiliary and pancreatic surgery Englishdetail HBP surgery used to be regarded high-risk and complicated. Nevertheless, the safety of such procedures has improved dramatically due to refinements in surgical procedures, improved surgical instruments and the development of operative support such as preoperative simulation and intraoperative navigation using the three-dimensional image analysis. In this video session, the latest updates on techniques for and perioperative support modalities for comlex HBP surgical procedures will be demostrated. 6.Techniques and ideas for difficult surgical diseases or conditions Englishdetail Surgical risks and difficulties differ between individual patients and their clinical conditions. Increased number of obese patients along with Westernization of dietary habits made surgery more challenging with difficulties in securing optimal exposure and anatomical orientation. These patients often have concomitant surgical risk factors such as diabetes mellitus and cardiovascular diseases. Tissues of cirrhotic patients are often fragile and associated with increased blood loss due to collateral circulation. The condition of the pancreatic texture and size of the main pancreatic duct which influence the chance of complications of pancreaticojejunostomy differ between pancreatic cancer and other conditions such as biliary cancer, IPMN and P-NET. In this video symposium, surgical techniques and ideas that reduce the chance of complications at various institutions are shared to tackle challenging cases and to improve safety of surgical procedures. 7.Changes in gastroenterological surgery by robotic surgery Englishdetail In April 2018, national insurance coverage for robotic surgery was expanded to include gastric, esophageal and rectal cancer. However, such procedures are only allowed at instututions with experienced surgeons, and prospective registry is mandatory. Since no extra-charge for robotic surgery was allowed this time, the price of the robotic systems and their running cost are major concerns. In this video symposium, the current status of robotic surgery will be demonstrated, and future challenges of the procedure in gastroenterological surgery will be discussed. 8.Strategy for redo surgery in gastroenterological surgery Englishdetail In the field of gastroenterological surgery, some cases require redo surgery, such as repeat resection for recurrent malignancy, recurrence or deterioration of benign diseases and postoperative complications. In redo surgery, difficulty with dissection and anatomical deviation by adhesion could lead to inadvertent organ injury. In this regard, redo surgery is expected to benefit from expanding use of antiadhesive materials and endoscopic surgery. In this video session, case presentation and the results of preventive measures for postoperative adhesion as well as varous surgical techniques and their results in redo surgery including indications, approach (open vs. endoscopic), surgical tips and problems associated with redo surgery will be discussed.
