The SIOG National Representatives (NRs) Committee is a strategic body within SIOG, playing a key role in connecting the organisation with members, institutions, and experts worldwide.
SIOG NRs work closely with SIOG committees to support the design, implementation, and evaluation of activities, helping ensure a coordinated and globally relevant approach across all SIOG initiatives.
Why become a National Representative (NR)?
SIOG’s work is built on strong collaboration and partnership. Recognising the importance of national contexts, SIOG aligns its activities with local capacities, resources, and clinical practices.
As highlighted by the World Health Organization in its report on ageing and health, population ageing requires coordinated and context-specific action. National Representatives play an important role in supporting this effort by strengthening the visibility of geriatric oncology and encouraging collaboration between oncologists, geriatricians, and other disciplines.
They also contribute to building relationships with health authorities and supporting the development of practical measures to improve cancer care for older adults, including strengthening the healthcare workforce. NRs help raise awareness of progress and challenges within their countries, taking into account the specificities of each health system.

SIOG Country Groups
SIOG Country Groups support National Representatives in strengthening collaboration and advancing geriatric oncology at the national level. If you are interested in joining or establishing a Country Group in your country, please contact the SIOG Head Office.
