NCCN Guidelines for Patients
Brain Cancer – Gliomas, Version 1.2016
There are other options if it is known before surgery
that a maximal safe resection can’t be done. These
options are a subtotal resection, open biopsy, and
stereotactic biopsy. The removed tissue will be tested
to confirm diagnosis and cancer grade.
Tests after surgery
Tissue removed by any type of surgery will be sent
to a pathologist for testing. The pathologist will
confirm if there’s cancer, and if so, the cancer grade.
Molecular markers of gliomas will also be assessed.
You should receive a brain MRI if you had a gross
total or subtotal resection. MRI should be completed
within 24 to 72 hours after surgery. Images will be
made with and without contrast. This test can confirm
how much of the cancer was removed. If you can’t
have MRI, you may receive a CT scan with and
Glioblastomas and gliosarcomas
