Newly diagnosed glioblastoma in geriatric (65?+) patients: impact of patients frailty, comorbidity burden and obesity on overall survival.

ABSTRACT: OBJECT:Increasing age is a known negative prognostic factor for glioblastoma. However, a multifactorial approach is necessary to achieve optimal neuro-oncological treatment. It remains unclear to what extent frailty, comorbidity burden, and obesity might exert influence on survival in geriatric glioblastoma patients. We have therefore reviewed our institutional database to assess the prognostic value of these factors in elderly glioblastoma patients. METHODS:Between 2012 and 2018, patients aged???65 years with newly diagnosed glioblastoma were included in this retrospective analysis. Patients frailty was analyzed using the modified frailty index (mFI), while patients comorbidity burden was assessed according to the Charlson comorbidity index (CCI). Body mass index (BMI) was used as categorized variable. RESULTS:A total of 110 geriatric patients with newly diagnosed glioblastoma were identified. Geriatric patients categorized as least-frail achieved a median overall survival (mOS) of 17 months, whereas most frail patients achieved a mOS of 8 months (p?=?0.003). Patients with a CCI?>?2 had a lower mOS of 6 months compared to patients with a lower comorbidity burden (12 months; p?=?0.03). Multivariate analysis identified "subtotal resection" (p?=?0.02), "unmethylated MGMT promoter status" (p?=?0.03), "BMI?
