Clinical Scorecard: Intraoperative Brain Mapping Techniques for Glioma Resection: An In-Depth Analysis of the UCSF Protocol

At a Glance

Key Highlights

• Maximal resection of contrast-enhancing and FLAIR borders is the gold standard for glioma treatment.
• Intraoperative mapping is associated with fewer neurological deficits and higher rates of maximal resection.
• Awake and asleep mapping techniques are utilized to enhance patient safety and comfort.
• Preoperative imaging with DTI and MEG is critical for surgical planning.
• The onco-functional outcome (OFO) classification scheme helps assess resection outcomes.

Guideline-Based Recommendations

Diagnosis

• Utilize MRI with and without gadolinium, DTI, and MEG for preoperative assessment.

Management

• Perform maximal resection while preserving functional status.

Monitoring & Follow-up

• Assess neurological function postoperatively to evaluate for deficits.

Risks

• Increased risk of neurological deficits with larger resections, especially near functional cortex.

Patient & Prescribing Data

Adults with diffuse gliomas, particularly those with IDH mutant astrocytomas and oligodendrogliomas.

Supratotal resection beyond FLAIR margins is associated with lower recurrence risk and improved survival.

Clinical Best Practices

• Implement intraoperative motor and language mapping to minimize neurological deficits.
• Utilize asleep conditions for motor mapping to enhance accuracy and patient comfort.
• Incorporate DTI and MEG in preoperative planning to improve surgical outcomes.
