Although geriatric assessment (GA) reduces chemotherapy toxicity by detecting pre-existing conditions, GA can be difficult for oncologists to perform because of limited time and resources. We aim to determine the prevalence of pre-existing geriatric conditions that could be detected if GA were performed during routine oncology care. Methods: We used the Health and Retirement Study (HRS) linked with Medicare (1998-2016) to identify adults age >65 with poor prognosis cancers (median overall survival < 1 year). The HRS is a biennial nationally representative survey that asks about pre-existing geriatric conditions. Using the interview prior to the cancer diagnosis, we determined the presence of conditions included in GA: functional status (i.e. difficulty with climbing stairs, walking one block, getting up from a chair, bathing or showering, taking medications, and managing money), falls and injurious falls, unintentional weight loss, self-rated health, social support, mentation, advanced care planning, use of pain or sleep medications, and mobility. To identify groups with the highest prevalence of pre-existing geriatric conditions, we stratified results by age (adjusted for gender) and gender (adjusted for age). Results: Our study included 2,121 participants. At the time of cancer diagnosis, mean age was 76, 51\% were female, 79\% were non-Hispanic White, 26\% had lung cancer, 14\% had a GI cancer, and 60\% had other metastatic cancers. Mean time between the HRS interview and cancer diagnosis was 12.7 months. The median overall survival of the entire cohort was 9.6 months with a 45\% 1-year survival rate. The adjusted prevalence of pre-existing geriatric concerns were as follows: 65\% had difficulty with climbing several flights of stairs, 27\% had difficulty with walking one block, 47\% had difficulty getting up from a chair after sitting down, 12\% had difficulty in bathing or showering, 6\% had difficulty taking medications, 11\% had difficulty in managing money, 35\% had a fall in the last 2 years with 12\% of participants reporting injury after their fall. Those who were aged 85+, vs those aged 65-74, had higher rates of conditions indicative of cognitive impairment (e.g. 12 vs 4\% had difficulty taking medications, p = 0.000, 26\% vs 6\% had difficulty managing money, p = 0.000) and physical impairments (e.g. 54\% vs 30\% had falls, respectively, p = 0.000). Rates of geriatric conditions indicative of physical impairment were higher in women vs men (e.g. 72\% vs 58\% had difficulty climbing stairs, p = 0.000 and 52\% vs 41\% had difficulty getting up from a chair, p = 0.000). Conclusions: Patients with poor prognosis cancers have high rates of pre-existing geriatric conditions that can be detected by GA. Geriatric assessments could find important impairments that could be addressed prior to cancer therapy to reduce adverse effects.12044Background: Older adults with poor prognosis cancers are more likely to experience toxicity from cancer-directed therapies.
