What is Craniospinal treatment?
Craniospinal irradiation (CSI) is a radiation technique that is used in the treatment of central nervous system malignancies that have a substantial risk of subarachnoid spread. Medulloblastoma is the most common diagnosis in children for which CSI is part of the standard of care.
What is Craniospinal irradiation?
Craniospinal irradiation (CSI) is a radiation technique used for patients with central nervous system malignancies, such as medulloblastoma and primitive neuroectodermal tumors.
What is the Craniospinal axis?
The craniospinal axis is considered as having two tissue compartments, brain (b) and spine (s), with two phases, solid tumor (t) and cerebrospinal fluid (f), within each compartment (Figure 2).
What is Craniospinal compartment?
The cranio-spinal (CS) compartment is filled with the cerebrospinal fluid (CSF) and sealed by the thick dura mater. The individual compliances of the cranium and the spinal canal sub-compartments add up to determine the overall compliance of the CS system [1].
What angles are used for brain and spine irradiation?
Two bilateral fields were used for whole brain and two posterior-oblique fields with 30° wedge at gantry angles 45° and 315° to cover cervical and part of thoracic spine (mostly up to T8-T9).
Can a brain tumor be treated without surgery?
Radiation therapy, also called radiotherapy, is the use of high-powered rays to damage cancer cells and stop them from growing. It is often used to destroy tumor tissue that cannot be removed with surgery or to kill cancer cells that may remain after surgery.
How can you reduce intracranial pressure?
The most urgent goal of treatment is to reduce the pressure inside your skull. This can be done in a number of ways, including: placing a shunt through a small hole in the skull or in the spinal cord to drain excess cerebrospinal fluid. using medications like mannitol and hypertonic saline to lower pressure.
Can radiation completely shrink a tumor?
Radiation – more powerful than an X-ray – brings many benefits to today’s cancer patients. It can diagnose, shrink and even kill off tumors.
