Summary
Neuroendoscopic biopsy offers a new approach for treating deep-seated solid intraparenchymal tumors. This minimally invasive technique, combined with stereotaxy, shows promise in diagnosis and management of these challenging brain tumors.
Area of Science:
- Neurosurgery
- Oncology
- Medical Technology
Background:
- Endoscopic biopsy is standard for intraventricular/cystic tumors.
- Solid intraparenchymal tumors were previously not candidates for endoscopic procedures.
Observation:
- Six patients with deep-seated or multiple intraparenchymal tumors underwent neuroendoscopic biopsy with stereotaxy.
- Histological diagnoses included malignant glioma and malignant lymphoma.
Findings:
- Complete tumor removal was achieved in one patient.
- Tumor resolution occurred in three patients with adjuvant radiotherapy and chemotherapy.
- Tumor growth was controlled in one patient.
Implications:
- Neuroendoscopic treatment is a viable option for managing deep-seated or multiple intraparenchymal tumors.
- This approach may improve outcomes for patients with previously untreatable brain tumors.
