Dear friends and colleagues,

It is our great pleasure to invite you to the 5th International Chronic Graft-versus-Host Disease Symposium that will be organized in Zagreb, Croatia, from April 15-16th, 2021. Depending on COVID-19 epidemiology situation, the symposium will be organized mostly or completely as a virtual meeting.

Approximately 50% of transplanted patients will develop chronic graft-versus-host disease (cGvHD) which can last for many years causing severe medical, social and quality of life problems. However, more than ever before, the tools are at our hands to address cGvHD conclusively and improve outcomes of patients after alloHSCT. Such progress in a relatively rare and complex disease can be achieved only by the assertive interdisciplinary and multicenter international collaboration.

This 5th International cGvHD Symposium in Zagreb brings together prominent experts in the field of cGvHD from Europe, United States of America, and Canada. Symposium will be divided in several sections: 1) Highlights from the newest 2020 NIH cGvHD consensus project, 2) Chronic GvHD progress review 3) Interactive cases for Hematology Residents and young Hematologists, and 4) Future projects proposals.

The goal of the meeting is to disseminate the most current knowledge regarding cGvHD, and to provide a venue for networking and establishing contacts for our future collaborations in addressing cGvHD. This event is expected to create a critical mass of investigators and colleagues who will carry this field in the near future. It is dedicated to physicians and scientists who are engaged in management, research, and advancing care of alloHSCT patients.

It is with delight that we invite you to attend and be part of this unique advanced continuing education experience.

With warm regards,
