Abstract

Objectives To determine if readily obtainable markers of frailty predict disease-free survival (DFS) in elderly women with endometrial cancer treated with curative intent. Methods 88 consecutive women ≥ age 60 treated with surgery, chemotherapy and radiation for stage I–IV endometrial cancer were included. We considered the following health deficits as markers of “frailty”: albumin < 3.5 mg/dL, hemoglobin < 10 mg/dL, BMI < 20 kg/m,2 unintentional weight loss, ECOG performance status ≥ 2, history of osteopenia or osteoporosis and Charlson comorbidity score. Kaplan–Meier estimates and Cox proportional hazards models of DFS were calculated. Results The median age was 68.5 (range 60–88 years). The majority of women (65/88) had at least one frailty factor at baseline and 23/88 had two or more. All women received radiation and chemotherapy. Treatment was delayed, modified or truncated in 46% (40/88) of women due to treatment-related toxicity. Age (< 70 vs. ≥ 70 y) did not independently predict toxicity or recurrence risk. Women with at least one baseline frailty factor had twice the risk of disease recurrence (HR = 2.21;95% CI:1.02–4.80) when adjusted for age, stage, grade and Charlson score. The 3-year DFS was 77% in those with no frailty markers and 48% in those with at least one (p = 0.02). The presence of a frailty marker also predicted shortened overall survival (HR = 2.34;95% CI:1.08–5.03) irrespective of treatment administered and stage of disease. Conclusions A combined frailty measure was a more robust predictor of DFS and OS than patient age, tumor characteristics and comorbidities in this cohort of older women with very good functional status.
