|Brain - Benign||
Meaning: Benign Brain Lesions are small space occupying areas in the brain that are slow growing and does not carry risk of aggressive growth locally or systemically. Still because of mass effect they may cause symptoms of headache/ vomiting seizures or related to the specific area of the Brain where they are located. Beningn Brain Lesions usually can be kept under close observation till the time they get symptomatic.
Common types of benign diseases are: Acoustic Neuroma/ Schwannoma / Arteriovenous Malformation (AVM)/ Cavernous Sinus malformations / Craniopharyngiomas/ other small Pituitary or pineal tumors / Glomus Jugulare Tumors/ Hemangioblastoma/ Meningiomas/ Parasellar Meningioma
Line of Treatment:
CyberKnife: CyberKnife is a good option for ablative dosages that can be used as a valid alternative to surgery. Like Gamma Knife, Cyberknife works on delivery of very high ablative dosages in single or small number of sessions with precisions equal to or even more than Conventional Gamma Knife procedure. It has benefits of being non invasive and does not need Anaesthesia or blood loss. Apart from being used as alternative to surgery, CK is also indicated for post op residual or recurrent cases. Also it can be used as a boost to Conventional Radiation - EBRT.
Alternate: Surgery remains the main stay of treatment but many cases may not be fit for surgery beacuse of : Medical Inoperability, Close Proximity to critical Brain area making surgery risky. In such cases
|Brain - Malignant||
Meaning: A benign or malignant growth in the brain. Primary brain tumors initially form in brain tissue. Secondary brain tumors are Cancers that have spread (metastasized) to the brain tissue from tissue elsewhere in the body. Brain Tumors can occur in people of any age.
Common types are Primary: Astrocytomas/ High Grade Gliomas/ Glioblastoma; Brain stem Glioma; Metastasis: From primaries like Head and Neck, Lung, Breast, Esophagus, Pancreas, Liver, etc
Line of Treatment:
CyberKnife: CyberKnife is used as a boost, for post op residual or recurrent cases.
Alternate: Unlike Benign Lesions, Malignant Lesions have more risks of aggressive growth locally and also more chances of incomplete response to treatment and also greater risk of recurrences. Surgery again remains the mainstay of treatment. Most cases will be offered Conventional Linear Accelerated Radiotherapy treatments for 5-6 weeks as indicated.
|Brain and Spinal Cord Tumors||
Meaning: Spinal Cord Tumors can be either Benign, Malignant primary that is primarily arising from the spine or has come from some other primary site and Tumor cells get deposited and start growing in spinal area. A spinal tumor or a growth of any kind can affect nerves in the area of the Tumor, leading to pain, neurological problems and sometimes paralysis. Whether Cancerous or not, a spinal Tumor can threaten life and cause permanent disability.
common types are: Selected solitary metastases / Primary treatment of classically radioresistant solitary tumors, i.e., melanoma, renal cell, sarcoma/ Benign spinal tumors (schwannomas, neurofibromas, meningiomas, etc)/ Solitary or limited spinal metastases from various primary tumours - naive or residual or recurrent / Spinal cord AV malformations
Line of Treatment:
CyberKnife: CyberKnife is a good options sparing normal spinal cord with more precision than most of the other radiation delivery techniques. For local therapy in spinal Tumors CyberKnife can deliver highly focussed Radiation sparing the surrounding normal tissues to a much greater extent.
Alternate: For Malignant primary and Benign Spinal Tumors surgery may be possible in some cases but at times Surgery will be difficult. In such cases. For spinal mets, Surgery is usually not possible and radiotherapy is most commonly indicated with supportive treatment of Chemotherapy needed to take care of the disease that has spread through blood stream.
