Cancer and older people. A research collection and commentary on the theme

Cancer disproportionately affects older adults, who account for the majority of diagnoses and deaths globally. However, research and clinical care often fail to adequately address their unique needs. This collection of studies in Age and Ageing highlights challenges and opportunities in geriatric oncology. The rising incidence of cancer in the older population, driven by demographic shifts and socioeconomic factors, underscores the need for targeted prevention and control strategies. Despite this, older adults remain underrepresented in clinical trials, with barriers including social isolation, healthcare professionals’ biases and a lack of dedicated studies. Frailty assessment is gaining ground as a key tool in geriatric oncology. Studies on frailty scores such as the Hospital Frailty Risk Score, and comprehensive geriatric assessment (CGA), show their ability to predict outcomes and guide interventions. CGA-based care has been shown to reduce treatment toxicity without compromising survival, yet its integration into routine practice remains limited. Treatment challenges are common, particularly with novel therapies like immune checkpoint inhibitors, which carry age-specific risks of adverse events. Tailored services are essential to address the diverse needs of older cancer patients. Research highlights the importance of improving communication around cancer screening for older adults and developing specialised care pathways for vulnerable populations, such as those with dementia. Continuity of care remains a significant challenge, requiring better coordination across healthcare providers. These findings emphasise the urgent need for age-attuned research, frailty-informed care models and tailored interventions to improve outcomes for older adults with cancer.
