Cancer Care in Patients with Comorbid Dementia

Summary

Patients living with both cancer and dementia represent a rapidly growing population in ageing societies worldwide. Dementia complicates the entire cancer trajectory, from initial staging through treatment decisions, symptom management and end-of-life care. Cognitive impairment may delay diagnosis, reduce the likelihood of standard curative interventions and increase reliance on emergency services. Families and healthcare teams face complex ethical and practical dilemmas when capacity is diminished, requiring repeated consultations and flexible scheduling. People with comorbid dementia are more likely to receive less aggressive oncology treatments and experience poorer survival, yet may benefit disproportionately from supportive and palliative approaches tailored to preserve quality of life. Holistic, person-centred models emphasise reasonable adjustments in communication, collaboration with caregivers and proactive symptom control. This integrated framework aims to minimise treatment burden, uphold autonomy where possible and address the heightened caregiver strain. Emerging guidelines advocate cross-disciplinary pathways that balance oncological efficacy with cognitive considerations, ensuring equitable access to screening, investigation and symptom relief for this vulnerable group.
