Central nervous system cancer
Central nervous system tumours (CNS) and peripheral nervous system (PNS) tumours occur when abnormal cells appear in the tissues of the brain or spinal cord.
When a tumour occurs in another part of the body and it spreads to the brain is often called a metastatic tumor.
There are also many benign tumour processes or even non-tumor benign pathologies that can benefit from this treatment.
Benign tumors include: benign meningiomas, acoustic neuromas and other cranial nerve neuromas, pituitary adenomas, chordomas, craniopharyngiomas, localized low-grade gliomas, glomus tumors, etc.
Likewise, there are benign non-tumor pathologies, including cerebral arteriovenous malformations and trigeminal neuralgia, among others, that can also be treated with radiotherapy.
These lesions generally have some common characteristics: they are small, well defined and often close to critical or very sensitive brain structures.
In order to treat these lesions, the use of Radiosurgery techniques in a single dose (SRS) or in a few sessions (ultra-hypofractionation) is fundamental, being essential when open surgery is not possible or it is not exempt from possible complications.
The irradiation applied in these cases is performed very precisely with Intensity Modulated Radiotherapy (IMRT), Intensity Modulated Volumetric Arc Therapy (VMAT), etc. and using different image-guided (IGRT) and surface-guided (SGRT) positioning techniques, reducing radiation to healthy sensitive organs to more than acceptable doses.
Type of Central nervous system tumours: Brain tumor.
