Challenges of caring for older patients with multimorbidity including cancer.

Introduction: As the population is ageing, the number of older patients with multimorbidity including cancer continues to increase. To improve care for these patients, the European Union-funded project "Streamlined Geriatric and Oncological evaluation based on IC Technology" (GERONTE) was initiated to develop a new, patient-centred, holistic care pathway. The aim of this paper is to analyse what challenges are encountered in everyday clinical practice according to patients, their informal caregivers, and healthcare professionals as a starting point for the development of the care pathway.
