The cornerstone of conventional treatments of malignant gliomas in adu
lts has been surgical debulking, radiation therapy and chemotherapy, A
lmost always a combination of these treatments is used, With these con
ventional treatments the outcome, as measured by survival and quality
of life, has remained universally dismal, Novel treatments, which are
at different stages of laboratory and clinical trials, may offer a ray
of hope for treatment of malignant gliomas, Development of these meth
ods are directly related to the discoveries, over the past two decades
, of cellular and molecular mechanisms involved in the genesis of brai
n tumors, Understanding of the mechanisms of tumor genesis may open ne
w avenues of effective treatments for this devastating cancer.
