Each year, hundreds of ancillary events are held adjacent to ASCO meetings and symposia. Ancillary events include, but are not limited to:

  • Advisory Board Meetings
  • Educational Events
  • Focus Groups
  • Hospitality Suites (in a meeting room)
  • Hospitality Desks
  • Internal Corporate Business Meetings
  • Investigator Meetings
  • Investor Meetings
  • Offices
  • Social Events

ASCO aims to provide superior customer service to members, volunteers, and meeting attendees. To achieve this aim, ASCO leadership requires all organizations (commercial and non-profit) that wish to hold functions during any ASCO meeting or symposium to complete an Ancillary Event Request. This applies to functions of any size or nature, and in any location. A completed Ancillary Event Request provides ASCO with the necessary information to assist members, volunteers, and meeting attendees with any questions that may arise.

Guidelines and Policies

Organizations submitting an ancillary event request should review the Ancillary Event Guidelines for additional information including:

  • Approved activities within ancillary space
  • Mailing lists
  • Marketing guidelines
  • Procedures for activities and events held within and outside of Symposia and Meeting space

In addition to the Guidelines above, ancillary event hosts must comply with the same policies as exhibiting companies.
