Brain Biopsy with Custom IHC

What is Brain biopsy with custom IHC (CoE) test?

A brain biopsy is processed into histology slides for routine stains and microscopic review; when morphology is insufficient for a definitive diagnosis, targeted IHC stains are applied to detect lineage, differentiation, and biomarker expression that distinguish tumor types and mimics. The COE (Center of Excellence) model indicates expert pathology review with flexible, indication-driven marker selection and reflex additions (e.g., IDH1 R132H IHC with sequencing reflex if negative) within an integrated report.

Why consider Brain biopsy with custom IHC (CoE) test?

• Improves diagnostic accuracy when routine histology is inconclusive, enabling definitive classification (e.g., astrocytic vs oligodendroglial vs embryonal tumors vs metastasis vs lymphoma vs infection/inflammation).

• Guides management by providing prognostic indices (e.g., Ki‑67) and lineage markers that influence surgery, radiotherapy, chemotherapy, targeted therapy, or need for additional molecular tests.

Who should get tested for Brain biopsy with custom IHC (CoE) test?

• Patients with radiologically suspicious intracranial or spinal masses where a tissue diagnosis is required and morphology alone may not resolve the differential diagnosis.
• Cases with small biopsies, unusual histology, or overlapping features where tailored IHC can discriminate between primary CNS tumors, metastases, lymphomas, granulomatous/infectious, or autoimmune processes.

Brain biopsy with immunohistochemistry (IHC) combines tissue sampling from a brain lesion with targeted antibody-based staining to identify cell lineage, tumor subtype, and prognostic markers, enabling precise, integrated diagnoses that guide therapy. IHC complements morphology and increasingly pairs with molecular tests to align with modern WHO glioma classifications and tailored treatments.
