The importance of the blood levels of homocysteine, folate and vitamin B12 in patients with primary malignant brain tumors.

Purpose: Glioblastoma multiforme and anaplastic astrocytoma represent one of the most frequently occurring primary brain tumors with dismal survival rates. The aim of our study was to investigate whether values of homocysteine, folates and vitamin B12 can be prognostic markers in relapse diagnosis, treatment and monitoring of adult patients with malignant brain tumors.

Methods: Twenty-seven patients from the Neurosurgical Clinic, Clinical Center of Serbia with diagnosed malignant brain tumors (anaplastic astrocytoma GR III and glioblastoma multiforme GR IV), were included in the study.
