Officers & Executive Committee

President - Simon Law

Simon Law
The University of Hong Kong, China

I have been an active member of ISDE since the early 1990s, and have attended all its congresses since. As an esophageal surgeon, I have special affinity for the society, as my career grew parallel with it. My closer association with ISDE commenced when I became an editor of Diseases of the Esophagus in 1999, and associate editor since 2010. I have served as co-chairman of the scientific committee for the ISDE world congress in Vancouver in 2014. Currently I am co-chairman of the Education Committee. I have been actively involved in development of many international initiatives on esophageal surgery, including as member of the Worldwide Esophageal Cancer Collaboration, Esophageal Complication Consensus Group, and working group on Enhanced Recovery after Esophagectomy. Engaging with other societies, I also hold positions, such as Consultant for International Society of Digestive Surgery, National Delegate to the International Surgical Society, Secretary General of the American College of Surgeons (Hong Kong Chapter), Asia II Representative of the Member Services Committee of the Society for Surgeons of the Alimentary Tract (SSAT). In addition I am honorary member of the American Surgical Association as well as European Surgical Association. Residing in Hong Kong, I have extensive network with physicians from the Asia Pacific region, not just in countries traditionally with close association with ISDE (such as Japan), but particularly in China, where growing involvement is evident in recent years. I hope that with my experience in the society, my international involvement, my network, I can continue to serve ISDE and form bridges between East and West. I am humbled by the achievement of the ISDE, and will be honoured to contribute more to the society in the future.

President-Elect - Nicholas J. Shaheen

Nicholas J. Shaheen
University of North Carolina, USA

I am a gastroenterologist and professor of medicine at the University of North Carolina School of Medicine, and Chief of the Division of Gastroenterology and Hepatology at UNC. I specialize in endoscopic treatment of precancerous and cancerous conditions of the esophagus, and am an active clinical researcher in these areas. I am a longstanding member of the ISDE and support its mission. The unique multidisciplinary and international nature of the group provides a perspective not found elsewhere, and leads to enriched and stimulating academic interaction. I have enjoyed serving as a co-chair of the planning committee for our upcoming virtual Congress, and addressing the challenges presented by mounting a meeting in the time of a pandemic.

I have extensive administrative experience, both at my institution and in professional organizations, which make me well-suited for this position. In addition to managing our GI division and the clinical research center here at UNC, I have served as the Director of the American College of Gastroenterology Institute, the research and education arm of the ACG. I have also been a trustee of that organization for the past decade. I also served the American Gastroenterological Association as head of the Clinical Practice section, and a member of AGA Council. I am highly collaborative and believe that the best ideas to engage a professional society usually originate from the membership up, not the leadership down. I am honored to be elected in this position, and will work hard to promote the ISDE in national and international venues.

I am honored to be the Vice President of International Society of Disease of the Esophagus. I have been an active member of ISDE since the early 1990s, and have attended all its congresses since. As an esophageal surgeon, I have special affinity for the society, as my career grew parallel with it. My closer association with ISDE commenced when I became an editor of Diseases of the Esophagus in 1999, and associate editor since 2010. I have served as co-chairman of the scientific committee for the ISDE world congress in Vancouver in 2014. Currently I am co-chairman of the Education Committee.

I hope that with my experience in the society, my international involvement, my network, I can continue to serve ISDE and form bridges between East and West. I am humbled by the achievement of the ISDE, and will be honoured to contribute more to the society in the future.

Vice President - Lorenzo Ferri

Lorenzo Ferri
Montreal General Hospital, Montreal, QC, Canada

It is an honour to serve on the ISDE Board of Directors as Vice President, a society I have faithfully served since attending my first meeting in Adelaide over 15 years ago. I am an esophageal surgeon at McGill University in Montreal Canada and director of the division of Thoracic and Upper Gastrointestinal Surgery at this institution.

Directors

Long-Qi Chen (CSDE)

Long-Qi Chen
West China Hospital, China

Being an active member of ISDE since 1994, I attended most of the ISDE conferences since 1998. It was a significant experience for me to witness the growing and strengthening of ISDE, now to be the most representative and impacted societies in the world. As for China, I founded Chinese Society for Diseases of the Esophagus (CSDE) in 2015 in order to improve the current unsatisfactory quality of medical care. The Society is focused on improving the medical service quality by enhancing medical education and training, bridging international collaboration and coordinate clinical studies.

As one of the 2 affiliated societies to ISDE, CSDE represents a combined initiative amongst Chinese surgeons, physicians, pathologists and scientists to study esophageal diseases. Later on, we promoted over 120 abstracts submission and 90 attendees to ISDE 2016 in Singapore. It would be the similar expectation for ISDE 2018 in Vienna. What’s more, the “CSDE Annual Working Conference 2020 ” was successfully held in Shenzhen, China. It brought together multiple specialties focused on the clinical management and research of patients with esophageal diseases. Since its inception, CSDE has been playing as an excellent platform for the academic exchange of clinical and scientific knowledge on the latest developments.

I am willing to initiate or chair some task forces assigned by ISDE, already with experience with being enrolled in the WECC task force to define the 7th and 8th edition of TNM staging for esophageal cancer. I am keeping communication and also serving in other local relevant societies in China like Esophageal Cancer Committee, Chinese Anti-Cancer Association (CACA), and Esophageal Expertise Committee, Chinese Association for Thoracic Surgeons (CATS).

Amsterdam University Medical Centers (UMC), Amsterdam, The Netherlands

It is a great honor for me to be a Director of the ISDE Board.  I am currently a consultant upper-GI surgeon and principal investigator at the Amsterdam UMC, University of Amsterdam in Amsterdam, The Netherlands. I have been proctoring minimally invasive esophagectomies and gastrectomies at different centers in the Netherlands and abroad. My main research topics are lymph node metastases and extent of lymphadenectomy in esophageal and gastric cancer (e.g. the international TIGER-study), minimally invasive upper GI surgery and postoperative outcome, quality of life following upper GI surgery and surgical techniques (e.g. RCT omentectomy vs omentum preservation in gastrectomy – OMEGA-trial, transhiatal versus transthoracic esophagectomy – national IVORY-study).

Currently, I serve as board member of the Dutch Society for Gastro-Intestinal Surgery (NVGIC) and of the European Society for Diseases of the Esophagus (ESDE). Also, I am a member of the scientific committee of the ESDE/IGCA-joint 2021 congress, the ISDE 2022 world congress, and in the organization of the future ESDE and 2025 IGCC congresses, which will be organized in Amsterdam. Furthermore, I contribute to several other (guideline) committees.

The ISDE is a very important society to me, bringing together disciplines involved in treatment of esophageal diseases from all over the world. This multidisciplinary approach is of great significance. I am an active member since 2013, and have attended all congresses since 2014. I have served on several ISDE committees previously and currently such as the Research & Database Committee; Esodata Membership Bylaws and Budget Subcommittee, the Membership Committee (chair) and the Guidelines Committee.

I am honored to serve as a director on the ISDE board and would make great effort to further develop multidisciplinary and international collaboration in the interests of the international society for diseases of the esophagus.

Ken Kato


Ken Kato
National Cancer Center Hospital, Japan

I am a medical oncologist and chief of Department of Head and Neck, and Esophageal Medical Oncology, and Gastrointestinal Medical Oncology, National Cancer Center Hospital, 2020-2022, and chief, Biobank Translational Research Support Section, Clinical Research Coordinating Section, Clinical Research Support Office, National Cancer Center Hospital. My primary interest is chemotherapy and chemoradiotherapy for oesophageal, esophagogastric, and gastric cancer. I am a group coordinator of the Japan Esophageal Oncology Group of JCOG, the most significant clinical trial group for cancer in Japan.

Our group has conducted clinical trials to develop new chemotherapy for metastatic disease and early oesophageal cancer in multimodality therapy. As a study coordinator, I conducted the randomized phase III trial, which compared the surgery and chemoradiotherapy for clinical stage I oesophageal squamous carcinoma, named JCOG0502, which reported the non-inferiority of chemoradiotherapy to surgery. The randomized phase III trial of neoadjuvant therapy for resectable oesophageal squamous cell carcinoma, named JCOG1109, showed superior survival of triplet-chemotherapy over doublet-chemotherapy. This trial gave a new aspect to neoadjuvant therapy for esophageal cancer.

To develop new drugs, such as immune-checkpoint inhibitors, I committed to the international phase III trial of oesophageal cancer as a steering committee member, for example, ATTRACTION-3 KEYNOTE-590, CheckMate-649, RATIONALE-306, and others. 

I am a director of the Japan Esophageal Society (JES) and am committed to international conferences in Asia and the public relations activity of JES. I am honored to be serving on the ISDE Board of Directors  and I will work hard to promote the ISDE in national and international venues.
