March 20, 2020:

Dear Colleague,

The 2020 MASCC/ISOO Annual Meeting is postponed to 24-26 June 2021 in the same location – Seville, Spain.

This postponement is due to the COVID-19 pandemic, which has significantly worsened since our last communication. It takes into account the health and safety of attendees, as well as the border closures and travel restrictions that are currently in place. The decision is based on consultation between the MASCC Executive Committee, the MASCC Board, ISOO, and our conference organizers MCI.

We will email registered delegates, invited speakers, and sponsors with additional details within 30 days. For all bookings/payments made through the meeting website (registration, hotel, workshops, dinner, content capture), delegates will be given the option to have these bookings automatically transferred to the June 2021 meeting or to request a refund. We will give you a few months to make that decision. All accepted abstracts will be honored for the June 2021 meeting. You will also have the option to update or withdraw your submitted abstract.

Please change or cancel any travel or hotel arrangements you have made independently. Most airlines are currently waiving change fees and providing a full credit for tickets that normally do not allow changes.

As you may know, our 2021 meeting was originally planned for Yokohama, Japan, as a joint meeting with the Japanese Association of Supportive Care in Cancer (JASCC). We are very thankful to our partners at JASCC for their understanding of this situation; we plan to hold the meeting in Japan in another year. The 2022 meeting is still planned for Toronto.

Thank you for your patience and understanding. We hope to see you in Seville next year!
