Group Registration
Company Administrators enter delegate registrations online. The Company Administrator will have exclusive rights to manage registrations for all delegates. Administrators must first set up a contact account with general company information.
Important note about registration fees and hotel reservations: All group hotel reservations for the ASCO® Breakthrough 2026 must be secured directly through the ASCO® Breakthrough 2026 Customer Service Center. Until you secure your group hotel reservations and make payment, you will be charged the applicable registration fee plus an additional fee of $200 per person.
Please note: A unique email address is required for each delegate. The Meeting offers several value-added products to which access depends on having a unique email address for each user.
There are 2 ways to register for the ASCO® Breakthrough 2026 depending on the size of your group:
Online (any number of delegates may be submitted)
Company Administrators enter delegate registrations online. The Company Administrator will have exclusive rights to manage registrations for all staff working in the booth. Administrators must first set up a contact account with general company information.
New registrations, changes and/or cancellations can be made online any time using the delegate registration website. To substitute one delegate for another, the company administrator must cancel the first registration and create a new registration using the new delegate's information.
Import (must submit 50 or more delegates)
If you meet the minimum requirement of delegates, you may submit the registrations using the import spreadsheet. Administrators must first set up a contact account with general company information. Once the spreadsheet is imported, administrators should use the delegate registration website to make additional registrations, changes, or cancellations.
