Neuro-oncology
Neuro-oncology is a specialized field of medicine focused on diagnosing and treating tumors of the brain and spinal cord. As one of the most complex and challenging branches of oncology, neuro-oncology requires a multidisciplinary approach involving neurologists, neurosurgeons, medical oncologists, and radiation oncologists.
Brain and spinal cord tumors can be benign (non-cancerous) or malignant (cancerous). Regardless of their classification, these tumors can significantly impact neurological functions and overall quality of life. Understanding neuro-oncology is crucial for early diagnosis, treatment, and management of such conditions.
Types of Brain and Spinal Cord Tumors
1. Primary Brain Tumors
- Gliomas – Arise from glial cells and are the most common type of brain tumor.
- Meningiomas – Develop in the meninges, the protective membranes covering the brain and spinal cord.
- Medulloblastomas – Typically found in children and originate in the cerebellum.
- Pituitary Adenomas – Affect the pituitary gland, impacting hormone regulation.
- Schwannomas – Originate from Schwann cells and affect nerve function.
2. Metastatic Brain Tumors
Metastatic (secondary) brain tumors originate from cancer elsewhere in the body, such as lung, breast, or melanoma, and spread to the brain.
3. Spinal Cord Tumors
- Intramedullary tumors – Develop within the spinal cord, including astrocytomas and ependymomas.
- Extramedullary tumors – Grow outside the spinal cord but within its protective covering, such as meningiomas and schwannomas.
Symptoms of Neuro-Oncological Conditions
Symptoms of brain and spinal cord tumors vary based on their size, location, and type. Common symptoms include:
- Persistent headaches, especially in the morning
- Nausea and vomiting
- Seizures
- Vision or speech impairments
- Loss of balance or coordination
- Cognitive changes, including memory loss and confusion
- Weakness or numbness in limbs
Diagnosis of Brain and Spinal Cord Tumors
- Neurological Examination – A thorough assessment of cognitive and motor functions.
- Imaging Tests – MRI and CT scans help in visualizing tumors.
- Biopsy – A sample of tumor tissue is examined for malignancy.
- Lumbar Puncture (Spinal Tap) – In cases of suspected spinal cord tumors.
Treatment Options in Neuro-Oncology
Treatment strategies depend on tumor type, location, and patient health.
- Craniotomy – Surgical removal of brain tumors.
- Minimally Invasive Neurosurgery – Utilized for small or deeply located tumors.
- Spinal Decompression Surgery – Used for spinal cord tumors.
- External Beam Radiation – Targets tumor cells high-energy radiation.
- Stereotactic Radiosurgery (SRS) – A precise form of radiation therapy.
- Used for aggressive or metastatic tumors.
- Administered orally, intravenously, or via direct tumor injection.
- Uses drugs that specifically target tumor cells.
- Immunotherapy enhances immune system’s ability to fight cancer.
- Focuses on pain management and improving quality of life.
Treatment Options in Neuro-Oncology
- Precision Medicine – Tailoring treatments based on genetic profiles.
- AI & Machine Learning – Enhancing tumor detection and diagnosis.
- Brain-Computer Interfaces (BCI) – Assisting in post-treatment rehabilitation.
- Stem Cell Therapy – Investigated as a potential treatment option
