Chemotherapy in older adult gynecologic oncology patients: Can a phenotypic frailty score predict tolerance?

ABSTRACT: OBJECTIVE:Evaluate the ability of an office-administered phenotypic frailty assessment to predict chemotherapy tolerance in older adult gynecologic oncology patients, and describe practice patterns for chemotherapy administration in this population. METHODS:Prospective, single-institution cohort study of gynecologic oncology patients 65 or older initiating chemotherapy. Phenotypic frailty testing at an office visit encompassed components of two validated frailty assessments: Fried Score (physical testing and patient response) and FRAIL Scale (patient response only). Patients were followed through three cycles of neoadjuvant chemotherapy or six cycles of adjuvant chemotherapy. Standard statistics examined the relationship of frailty to chemotherapy regimen, ability to complete chemotherapy, and complications. RESULTS:Eighty patients were included, 65% with ovarian and 34% with endometrial cancer. On average 57% of patients were fit, 32% intermediately frail, and 11% frail. 68% received adjuvant chemotherapy versus 32% neoadjuvant. The majority (81%) received IV chemotherapy on a 21-day?cycle and 81% initially received a regimen consistent with standard-of-care chemotherapy (SOCC). Age was not associated with receiving SOCC, or tolerance or completion of chemotherapy. Frailty was associated with non-initiation of SOCC in all patients and inability to complete SOCC in adjuvant patients. Complications and regimen alterations were common but were not associated with frailty. CONCLUSIONS:There is a need to develop tools to help physicians predict chemotherapy tolerance among older adult gynecologic oncology patients in order to prevent both under- and over-treatment while minimizing morbidity. However, in this study phenotypic frailty assessment had limited predictive utility. Among adjuvant chemotherapy patients, frailty was associated with inability to complete SOCC and thus may be helpful in selecting patients appropriate for less aggressive chemotherapy regimens.

Project description:ObjectivesFinancial toxicity is increasingly recognized as an adverse outcome of cancer treatment. Our objective was to measure financial toxicity among gynecologic oncology patients and its association with demographic and disease-related characteristics; self-reported overall health; and cost-coping strategies.MethodsFollow-up patients at a gynecologic oncology practice completed a survey including the COmprehensive Score for Financial Toxicity (COST) tool and a self-reported overall health assessment, the EQ-VAS. We abstracted disease and treatment characteristics from medical records. We dichotomized COST scores into low and high financial toxicity and assessed the correlation (r) between COST scores and self-reported health. We calculated risk ratios (RR) and 95% confidence intervals (CI) for the associations of demographic and disease-related characteristics with high financial toxicity, as well as the associations between high financial toxicity and cost-coping strategies.ResultsAmong 240 respondents, median COST score was 29. Greater financial toxicity was correlated with worse self-reported health (r = 0.47; p < 0.001). In the crude analysis, Black or Hispanic race/ethnicity, government-sponsored health insurance, lower income, unemployment, cervical cancer and treatment with chemotherapy were associated with high financial toxicity. In the multivariable analysis, only government-sponsored health insurance, lower income, and treatment with chemotherapy were significantly associated with high financial toxicity. High financial toxicity was significantly associated with all cost-coping strategies, including delaying or avoiding care (RR: 7.3; 95% CI: 2.8-19.1).ConclusionsAmong highly-insured gynecologic oncology patients, many respondents reported high levels of financial toxicity. High financial toxicity was significantly associated with worse self-reported overall health and cost-coping strategies, including delaying or avoiding care.
