While low-grade astrocytomas (WHO grades 1-2) uncommonly enhance on MRI, many grade 3-4 astrocytomas enhance with gadolinium contrast agents. High-resolution MRI is now often used to provide intraoperative image guidance. CT: A CT scan may be useful in the acute setting or when MRI is con...
The progression-free survival rate was 71%, with a median follow-up of 32 months. Brown and colleagues (1993) used various chemotherapy regimens to stabilize 11 patients with clinically aggressive PAs that had progressed after surgical resection, with radiation therapy in 7 patients. Five of the...
A recent large prospective randomized phase III trial showed that the addition of TMZ during and after radiation therapy (RT) in newly diagnosed (nGBM) patients prolonged median overall survival by 2.5 months; perhaps more importantly, the 2-year survival rate for patients receiving TMZ and RT ...
High-grade astrocytomas are treated with a combination of surgery (if possible), radiation therapy, and chemotherapy (see Combination Cancer Therapy). The outlook is worse for children with a high-grade tumor, and overall survival is only 20 to 30% 3 years after treatment. More Information ...

The primary endpoint was overall survival (OS). The cohort was further divided into 5 subgroups, by their unique molecular and histomorphological profile consisting of: glioblastoma multiforme (GBM), diffuse- midline gliomas H3 mutated (DMG-H3), high-grade astrocytoma with piloid features (HAP),...
CONCLUSIONS Although the overall survival rate of children with low grade astrocytoma is excellent, significant long term disability occurs. Early diagnosis is essential to reduce postoperative cognitive morbidity. low grade astrocytoma surgery radiotherapy cognitive functioningFootnotes...
