Dr Ramakrishna Chowdhary HOD – Neurosurgery, Arete Hospitals Gachibowli, Hyderabad, explains that not all brain tumors require surgery, especially smaller tumors like meningiomas or low-grade gliomas that don't cause significant pressure on the brain. In general, most brain tumors, particularly gliomas, may need surgical intervention first to confirm the diagnosis, and then relieve symptoms, and reduce the mass effect on the brain.
The doctor discusses the latest surgical advancements, including navigation systems and intraoperative neuro-monitoring, that ensure safer and more precise tumor removal while protecting healthy brain tissue.
*Do All Brain Tumors Need Surgery?* *When is Surgery Necessary for Brain Tumors?*
Not all brain tumors require surgery. Small meningiomas and low-grade gliomas can often be monitored with regular MRI scans.
Surgery is required if the tumor shows growth or causes symptoms due to pressure (mass effect) on the brain.
*Surgical Need for Gliomas*
Gliomas are the most common type of brain tumor, originating from glial cells, the supportive cells of neurons.
*Gliomas range from Grade 1 to Grade 4*
Grade 1 and 2: Low-grade tumors, generally less aggressive, with a better prognosis.
Grade 3 and 4: High-grade tumors, more aggressive, with Grade 4 glioblastoma -multiforme having a survival rate of 12 to 18 months.
Surgery is often necessary for all gliomas unless confirmed to be low-grade.
*Advanced Surgical Techniques in Brain Tumor Surgeries*
Navigation Systems - Similar to a GPS, MRI images are used to guide surgeons with precision during the procedure, allowing them to reach and extract the tumor without harming surrounding healthy brain tissue.
Intraoperative Neuro-monitoring - Provides real-time feedback on brain activity during surgery. This helps ensure only the tumor is removed, while normal tissue is preserved.
Microscope Use - High magnification provided by the surgical microscope allows for precise tumor resection, minimizing damage to normal brain structures.
