The first UK geriatric oncology service at a tertiary cancer centre was established at the Royal Marsden Hospital in London. Its purpose is to conduct comprehensive geriatric assessments of patients with cancer on order to make referrals to multidisciplinary care. This descriptive study aimed to track its progress. It found that the service made a median of three referrals for each patient, most commonly to physiotherapy and occupational therapy. The frequency of referrals indicates that there is a high level of unmet need in older patients with cancer.
