Gliobasltoma, is the most common primary malignant and
fatal brain tumor. The mTOR-EGFR pathway is important
for treatment response and overall survival (OS). Our
translational research found that the molecular
signature of mTOR correlated with maximal rCBV ratio of
peri-enhancing tumor area (rCBVperi-tumor), the patients
with high rCBVperi-tumor had shorter OS, and combination
of rCBVperi-tumor and mTOR could improve prediction of
survival time in patients with glioblastoma.
