The 16th International Thyroid Congress

The 16th International Thyroid Congress Sketch

December 16 – 20, 2020, China

The 16th International Thyroid Congress (ITC) was held in China, between December 16 through 20, 2020.

The 16th ITC was hosted by the Asia & Oceania Thyroid Association (AOTA) and Chinese Society of Endocrinology (CSE), Chinese Medical Association (CMA). It was co-sponsored by sister societies Latin American Thyroid Society (LATS), European Thyroid Association (ETA) and American Thyroid Association (ATA). The congress was originally planned to be held in Xi’an, China in September, 2020. Due to the pandemic of COVID-19, it was eventually held as a virtual conference in December 2020.

Members of program organizing committee were Weiping Teng (Chair, AOTA, China), Chao Liu (AOTA, China), Minho Shong (AOTA, Korea), Masanobu Yamada (AOTA, Japan), Gabriela Brenta (LATS, Argentina), Claudia Pellizas (LATS, Argentina), José Augusto Sgarbi (LATS, Brazil), Duncan Bassett (ETA, UK), Anita Boelen (ETA, Netherlands), George Kahaly (ETA, Germany), Laura Fugazzola (ETA, Italy), Dagmar Führer (ETA, Germany), Sheue-yann Cheng (ATA, USA), Susan Mandel (ATA, USA) and Ralph P. Tufano (ATA, USA). Key members of local organizing committee were Jiajun Zhao (LOC Chair), Yiming Mu (LOC Co-Chair), Zhongyan Shan, Chao Liu and Bingyin Shi.

The concept of the 16th ITC meeting was “INTERDISPLINARY”. The program organizing committee contributed to a high-level scientific program. The program included 1 session regarding recent advances in thyroidology (4 lectures delivered by Robin Peeters, Gregory A. Brent, Fereidoun Azizi and Ana Luiza Maia, respectively), 12 plenary lectures (delivered by Zhongyan Shan, Fabian Pitoia, Anthony Hollenberg, Rosella Elisei, Yaron Tomer, Denise Pires de Carvalho, Greg Randolph, Ki-Wook Chung, Graham Williams, Jiajun Zhao, Ralf Paschke and Mikio Watanabe), 26 symposium sessions (80 lectures) and 3 award lectures (awarded by AOTA, ETA and ATA, respectively). Three awardees announced at this congress were Paul Yen (AOTA), Antonio Bianco (ETA) and Nadia Schoenmakers (ATA). The “INTERDISPLINARY” concept was reflected by cross-talks between different disciplines in symposium sessions, from basics science to translational research to various clinical perspectives.

The congress provided a great platform for international endocrine specialists, surgeons and other health professionals to present and discussed the up-to-date research and developments in thyroidology. Ninety-nine speakers were from 18 countries, and were members of AOTA (33), LATS (17), ETA (19), ATA (25) and non-society members (5). The number of registered participants was 1 190 from 45 countries. The congress videos had received over 25 000 hits as of March 31, 2021.

The 16th ITC congress was closed following the announcement that we would meet again in the 17th International Thyroid Congress, June 18-22, 2025 in Rio de Janeiro, Brazil.

The 16th ITC will be held as a virtual conference on December 16-20th, 2020.

Third Bulletin issued by AOTA, ETA, LATS, ATA and LOC/POC Regarding the 16th ITC

About the 16th ITC;

The 16th ITC will be held as a virtual conference on December 16-20th, 2020.

The global spread of the COVID-19 virus is continuing unabated, which naturally made it difficult to determine when to hold the ITC.  For this reason, a decision as to the best time for a rescheduled ITC was considerably delayed so as to judge the situation as well as possible.  It now seems evident that the pandemic will continue on into 2021 in many parts of the world.

Thus, after several discussions between the Chinese LOC and the AOTA regarding an alternative plan for the 16th ITC, LOC and AOTA reached an agreement to have the meeting online instead of in-person.

The 16th ITC will be held as follows based on the LOC’s suggestion and following the approval of leaders of all four sister societies.


Date: Wednesday 16 through Sunday 20 December, 2020

Registration: Registration is needed to get access to the session website.

Registration Fee: USD 150 (Member), USD 300 (Non-member), USD 100 (Trainee/Fellow /Nurse Practitioner)

CME credit will not be granted for this virtual conference.

Sessions: Recent Advances in Thyroidology, Plenary Lectures, Symposium Lectures, and Award Lectures.  All sessions will be prerecorded. The LOC is responsible for contacting the speakers and assisting them with recording.  There will be no meet the professor / debate and discussion and oral sessions / poster sessions.

Abstract submission is not necessary.


We look forward to a successful online 16th ITC.

There will be constant updates on the 16th ITC on the Conference Website ( including important dates.

We express solidarity with all our society members throughout the world and hope that everyone is staying as safe and healthy.

The 2nd Bulletin Regarding the 16th ITC from AOTA, ETA, LATS, and ATA

The 2nd Bulletin Regarding the 16th ITC from AOTA, ETA, LATS, and ATA

The 16th ITC has been postponed for now.

The global spread of the COVID-19 virus continues unabated. Our sister societies, their members, and our nations are all suffering catastrophic health impacts, severe financial consequences, travel restrictions, and schedule disruptions. Moreover, we all face an uncertain future with respect to recovery from this pandemic.

We all sincerely wish the 16th ITC to be held at a time that there may be a healthier and safer environment, financial recovery, lifting of travel restrictions, and less competing pressures on the schedules of our members. When recovery has occurred globally a greater number of individuals may be able to attend, thus contributing to a more robust, vibrant, and successful ITC.

A decision about the best time for a rescheduled ITC  will be delayed for as long as is needed to fully ascertain the situation. It is our hope that with additional delay more information about the trajectory of the pandemic may become available. It may then be possible to make a decision based on a greater amount of reliable information. We do not wish to prematurely re-schedule the ITC for a time that AOTA, ETA, LATS, and ATA members will not be in a position to fully support the Congress. 

We apologize about this delayed decision and appreciate that it does add to the uncertainty experienced by our international thyroid community. We all miss the opportunity to be able to engage professionally and personally with our fellow members. We will notify all our sister society members when a decision about the timing of the 16th ITC becomes possible.

We express solidarity with all our society members throughout the world and hope that everyone is staying as safe and as healthy as possible. We look forward to a happier time when this pandemic will no longer cast its shadow over our lives.

Bulletin regarding the 16th ITC

Bulletin regarding the 16th ITC

Every 5 years there is an International Thyroid Congress (ITC) hosted by one of our sister societies [Asian and Oceanic Thyroid Association (AOTA), Latin American Thyroid Society (LATS), European Thyroid Association (ETA), and American Thyroid Association (ATA)]. These meetings represent the best of inter-society collegiality harnessed for promoting clinical care, research and education in thyroidology. Each of these international meetings also represents an enormous undertaking on the part of the program organizing committee. This year’s 16th ITC in Xi’an, China has been planned over a period of 4 years.

The current devastating situation with the coronavirus outbreak in Wuhan in Hubei province has tragically caused an escalating number of deaths and illnesses. Our hearts go out to the Chinese people. We send all those affected our thoughts and prayers. The trajectory of the current outbreak is uncertain and our knowledge about the transmission and impact of the infection are ever evolving. The current level 3 travel advisory (no nonessential travel) has been extended beyond Hubei province to the whole of China, and the advisory may change. Depending on how the situation further evolves, these developments could seriously affect the upcoming ITC in China. Xi’an is about 400 miles northwest of Wuhan. The program organizing committee is actively staying abreast of the situation and will endeavor to keep members of our sister societies appraised of updated information.

At the current time we advise delaying making travel plans. Deadlines for abstract submissions and early bird registrations have been extended and announced on the conference website ( We apologize for this uncertainty and we commend the program organizing committee and the local organizing committee for their flexibility. We appreciate how difficult the situation is for the ITC organizers and that the situation may place all their creative and meticulous planning in jeopardy.

Please join us in extending our thoughts and sympathies to the Chinese people. We also thank the program organizing committee for their ongoing efforts at this difficult time. We would like to express our solidarity with the Chinese people and the ITC organizers. The ITC represents to us all the beating heart of the World Thyroid Community and a wonderful occasion to meet in a unique environment of shared aims, friendship and excellent science.

Please follow the updates on the websites of AOTA, LATS, ETA, and ATA.

AOTA Mourns the Loss of Prof. Jen-Der Lin

Prof. Jen-Der Lin, the Past President of The Endocrine Society of ROC and a longtime member of the AOTA, died Sep, 4th, 2019, at age 66.
As members of the Asia & Oceania Thyroid Association (AOTA), we express our sincere condolences to the family of Professor Jen-Der Lin who would have been bewildered by a loss of a beloved scholar.
He was one of outstanding scholars who performed excellent studies on thyroid cancer during his lifetime and served AOTA as a council member representing Taiwan from 2010 to 2015.
His warm heart and scientific brilliance have deeply touched his patients and his colleagues and friends in our region.
May he rest in peace while his spirit for patients’ care and teaching lives on.

Press Release for World Thyroid Day, May 25th, and International Thyroid Awareness Week, May 25th to 31st, 2019

A note from Ashok Bhaseen, President of Thyroid Federation International

“There are still many people living with some kind of thyroid disorder without diagnosis. The International Thyroid Awareness Week is now in its 11th year, and I promise, we at Thyroid Federation International and its member countries won’t rest until testing and diagnosis rates improve globally. This year we’re helping people to recognize the many faces of thyroid disorders so they can visit a healthcare professional and get tested as soon as possible.“

Look for patient programs on education and awareness in your country or visit the Thyroid Federation website in your country.

How to get involved in this year’s campaign

If you’re on social media, keep up with the campaign via our channels on Twitter and Facebook, and play your part in the global movement by using the hashtag #ITAW19. This will help us raise awareness of thyroid disorders, which affect more than 200 million people worldwide as per ATA (American Thyroid Association).

Why are we doing this?

ITAW, now in its 11th year, was created to highlight the detrimental impact that thyroid disorders have on people’s quality of life when left undiagnosed. Around 1.6 billion people worldwide are thought to be at risk, with hundreds of millions living with a thyroid condition right now.[i] Up to 60% of those living with a thyroid disorder are undiagnosed, and people may be needlessly struggling through their everyday lives without knowing the root cause of their symptoms.[ii]

However, once diagnosed, thyroid disorders are treatable, and the ITAW campaign is pushing hard to improve testing and diagnoses globally.
