Why SIOG

The Challenge

Populations around the world are rapidly ageing. According to the World Health Organisation (WHO), the number of people over 60 years is set to double by 2050. As a consequence, this will lead to increased demand for primary health care and long-term care as well as larger and better trained workforce that can respond better to the health needs of the elderly population. Universal health coverage and the health goal of the 2030 Agenda for Sustainable Development provide the foundations to adequately address the emerging societal challenges related to cancer amongst the ageing populations. As oncologists around the world shift their focus to the field of geriatrics, increased understanding of the impact of research, innovation and clinical practices for older adults with cancer is becoming of critical importance. Since the early 2000s, the International Society of Geriatric Oncology (SIOG) has positioned itself as an influential stakeholder of the strengthening of health workforce for improving the care of older patients with cancer around the world.

Why Geriatric Oncology 

  • The world population is ageing thanks to global improvement in health care and living conditions. It has been estimated that by 2020, the population of the  elderly worldwide would be more than 700 million with two-third in the developing countries [1] [2].
  • Advancing age is a high risk factor for cancer, with individuals over 65 accounting for 60% of newly diagnosed malignancies and 70% of all cancer deaths, mainly prostate, bladder, colon, uterus, pancreas, stomach, rectum, and lung carcinomas [1] [3] [4].
  • 14 million new cases were diagnosed in 2012 and this number could rise up to 22 within the next 2 decades [5].
  • In developed countries, half of the cancers already occur in patients aged 70 and older [5].

Why Focus on Older Patients

Majority of cancer diagnoses occur in people aged over 65 

  • Age related changes to tumour biology
  • Lack of research on effective treatments for older people
  • Increased vulnerability to the side effects of treatments
  • Inadequate screening and assessment instruments as validated tools in clinical practice

 

Global Perspectives: Why Geriatric Oncology

What is Geriatric Oncology About

  • How should oncologists be individualising their treatment approach based on the risks and benefits of therapy?
  • What instruments can help oncologists to have a better view of the patient’s overall health situation?
  • How does the cancer and the cancer treatment impact the aging process of the patient?
