253 PFS of elderly ovarian cancer patients might be predicted by G-8 geriatric screening tool – results of a retrospective cohort study

Introduction/Background* The aim of this study was to evaluate the impact of the preoperative global health status on the prognosis of patients with ovarian cancer (OC) older than 60 years, who received cytoreductive surgery. Methodology G-8 geriatric screening tool (G-8 score), Lee Schonberg prognostic index, Eastern Cooperative Oncology Group (ECOG) performance status and Charlson Comorbidity Index (CCI) were determined retrospectively in a consecutive cohort of elderly patients with OC. Univariate and multivariate Cox regression analyses and Kaplan-Meier method were performed to analyze the impact of the preoperative global health status on survival. Result(s)* 116 patients entered the study. In multivariate analysis adjusted for clinical-pathological factors, only the G-8 score retained significance as a prognostic parameter of PFS (HR: 2.009; 95%-CI [1.091-3.699]. 56 patients were classified as G-8 non-frail with an increased PFS compared to 50 G-8 frail patients (53.4% vs. 16.7%; p=0.010). A higher CCI was associated with decreased PFS (45.1% vs. 22.2%; p=0.012) but it did not influence the risk of recurrences or death (p=0.360; p=0.111, respectively). The Lee Schonberg prognostic index, the ECOG and mean age were not associated with survival. Conclusion* The G-8 score independently predicted PFS in elderly OC patients regardless of maximal surgical effort. Thus, it could be useful to assess surgical treatment based on frailty rather than age alone.
