ABSTRACT
Frailty represents a state of vulnerability that increases the risk of adverse health outcomes. In the last years, frailty has emerged as a good indicator of patient's functional reserve and it seems to be a predictor of negative outcomes in oncological patients. In this work, we analyzed the clinical utility of frailty as preoperative risk assessment tool in a brain tumor cohort from Donostia University Hospital (Spain). For that, we used several frailty tools consisting of questionnaires based on frailty phenotype (FRAIL scale), evaluating functional performance (Gait Speed) and a self-report questionnaire that includes variables related to the physical, cognitive and psychosocial domains of frailty (Tilburg Frailty Indicator). We identified a higher percentage of patients in vulnerable situation prior to surgery when using frailty tools compared to routine scal es such as Karnosfky score and Barthel Index. Remarkably, patients diagnosed with malignant tumors were frailer and presented significant less six-month survival than patients with benign tumors by all the frailty scales abovementioned. In line with this, the vast majority of patients that became pre-frail or frail after neurosurgery (by FRAIL scale) harbored a malignant tumor. Moreover, frailty status significantly correlated with patient's mortality and autonomy, but not with the presence of postoperative outcomes in our cohort. Taken together, our results show that frailty measurement, mainly by FRAIL scale, is a useful tool to evaluate preoperative risk in brain tumor patients as well as patient's prognosis after neurosurgery.
