Abstract

Background: We evaluated the prognostic impact of various global health assessment tools in patients older than 60 years with ovarian cancer (OC).

Methods: 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.

Results: 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 progression-free survival (PFS) (hazard ratio [HR]: 1.970; 95% confidence interval [CI] [1.056-3.677]; p = 0.033). Fifty-six patients were classified as G-8-nonfrail 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). The Lee Schonberg prognostic index, the ECOG, and age were not associated with survival.

Conclusions: 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.
