Geriatric oncology in 2040: Exploring potential realities and challenges. A diverse perspective

The average global life expectancy is predicted to increase to approximately 80 years by 2040 [1]. Cancer is an ageing-related disease, and its prevalence will also increase with this ageing of the population [2]. This rise in older adults living with cancer will demand innovation in service delivery, multidisciplinary collaboration, and a renewed focus on compassionate, patient-centred care. We are therefore compelled to rethink how we approach cancer diagnosis, treatment, and survivorship. This white paper explores the potential realities and challenges through a multidimensional lens, addressing the intersection of demographic shifts, rapid technological advancements, and the evolving needs of older adults living with cancer. Key areas examined include the integration of precision medicine and digital health tools, the adaptation of healthcare delivery models, and the implications for workforce training and resource allocation. The discussion highlights disparities in care, the importance of personalised interventions, and strategies to enhance quality of life for older adults with cancer. By anticipating these developments, the paper offers critical insights for policymakers (who set the rules and goals and allocate funding), health system leaders (who manage the day-to-day operations), clinicians and allied health professionals (who are patient-facing), and patients and caregivers, aiming to promote equity, innovation, quality and resilience in the care of older adults with cancer as we approach the next decade. The paper seeks to consolidate and clarify the diverse issues and opportunities that will emerge as the global population ages and the burden of cancer among older adults rises. With average life expectancy predicted to approach 80 years by 2040, and cancer recognised as a disease closely linked to ageing [3], the paper brings together expert perspectives to provide a sector-wide synthesis of the impending challenges. Its purpose is not to offer a conventional systematic review, but rather to serve as a strategic resource for policymakers, health system leaders, clinicians, allied health professionals, patients, and caregivers, informing the response to demographic shifts, technological advances and evolving patient needs. By consolidating insights on disparities in care, the necessity for personalised interventions, and strategies to enhance quality of life, the paper aims to inform and inspire innovation, equity and resilience in geriatric oncology as we approach the next decade.
