In this retrospective study, we evaluated the relationship between prognostic nutritional index, which was calculated from laboratory parameters, and clinical outcome including mortality in patients undergoing brain tumor surgery.
There are several predictors of clinical outcome in patients undergoing brain tumor surgery. Among those, nutritional parameters and calculated nutritional index are known to have ability to predict mortality and clinical outcomes in some patients with brain tumor. However, there are lack of consistent results on predictability of nutritional index and clinical outcome in patients undergoing brain tumor surgery.
