The International Society of Geriatric Oncology, also called SIOG (Société Internationale d’Oncologie Gériatrique) in French, is a multidisciplinary membership-based society with members engaged in more than 80 countries around the world. Our network includes geriatricians, medical oncologists, surgical oncologists, radiation oncologists, anaesthesiologists, nurses and allied health professionals. Founded in 2000, SIOG was officially registered as a not-for-profit organisation under the Swiss law in October 2012. Ever since, SIOG has established a long-standing history of implementing programmatic activities in the field of Geriatric Oncology via 3 strategic directions: education, clinical practice and research.

Powered by global collaborations, the SIOG network is committed to strengthening the national capacity for Human Resources for Health (HRH) in various countries and in promoting and advocating for the health agenda of the Sustainable Development Goal (SDG3) i.e. ‘Ensure healthy lives and promote wellbeing for all at all ages’.

Mission & Vision

The goal of SIOG is to strengthen the capacity of health professionals in the field of geriatric oncology, in order to optimise treatment of older adults with cancer.
SIOG operates via 3 strategic directions:

1. Education 

  • Disseminate knowledge in order to maintain a high common standard of healthcare in older cancer patients
  • Integrate geriatric oncology in the curricula for medical and nursing education to ensure a high standard of qualification for healthcare professionals 
  • Address the shortage of specialist oncologists/geriatricians & allied health staff in geriatric oncology 
  • Increase public awareness of the worldwide cancer in the elderly epidemic

2. Clinical practice 

  • Integrate geriatric evaluation (including comorbidities) into oncology decision-making and guidelines 
  • Improve the quality of prevention, diagnosis, treatment, and follow-up of older patients with malignancies 
  • Address issues of access to care, including the needs of the caregiver 
  • Develop interdisciplinary geriatric oncology clinics

3. Research 

  • Develop, test and disseminate easy screening tools
  • Create a clear and operational definition of vulnerability/frailty applicable to oncology 
  • Increase the relevance of clinical trials for older patients 
  • Improve research in the field of geriatric oncology 
  • Promote multidisciplinary, basic/translational research on the interface of ageing and cancer
