Conditions of eligibility Surgeons Geriatricians Medical and radiation oncologists Anaesthesiologists Perioperative nurses Rehabilitation specialists Dietitians Researchers in outcomes and implementation science The SIOG Surgical and Perioperative Optimisation Collaborative Interest Group was established to strengthen the role of surgery and perioperative care in the management of older adults with cancer. As the global population ages, more patients present with complex needs that extend beyond standard surgical pathways. While surgery remains a cornerstone of cancer treatment, older adults are less likely to access surgical care or achieve optimal outcomes, often due to gaps in assessment, optimisation, and coordinated care. The Collaborative was created to address this need by bringing together SIOG members across disciplines to advance a more integrated approach to surgical and perioperative care. It focuses on improving patient selection, optimisation, and recovery across the full perioperative pathway. Aligned with SIOG’s strategy, the Collaborative promotes multidisciplinary collaboration, research, [...]

The Swiss Group of Geriatric Oncology (SGOG) was established to advance care, research, and education in geriatric oncology and haematology. The group also works to increase awareness of these topics among the public and policymakers. SGOG brings together medical oncologists, haematologists, geriatricians, and nurses, fostering a multidisciplinary approach to improving care for older adults with cancer. It works closely with the Swiss Group for Clinical Cancer Research (SAKK), particularly through the SAKK Working Group on supportive care, palliative care, and geriatric oncology. As a recognised SIOG Country Group, SGOG actively contributes to SIOG’s global efforts in advancing geriatric oncology.

Older adults represent a significant proportion of the patient population in India. The standard retirement age in government service is 60 years, and this threshold is commonly used to define the older population. With increasing life expectancy, the number of people aged 60 and above is rising rapidly. While the overall population is projected to grow by 40% between 2006 and 2050, the population aged 60 and above is expected to increase by 270%, reaching nearly 20% of the total population by 2050. As cancer incidence increases with age, this demographic shift will lead to a growing number of older adults diagnosed with malignancies. These patients often face additional challenges related to comorbidities and age-related conditions, requiring tailored approaches to care. Survival outcomes also remain lower in this population, with more than half of cancer-related deaths occurring in individuals over 70. In India, cancer is often diagnosed [...]
