If the pilocytic astrocytoma is causing symptoms or a scan shows that the tumor is growing, a doctor may advise treatment. Surgery is the treatment of choice for this type of tumor. This is because total removal (resection) of the tumor is often curative.
What is the treatment for pilocytic astrocytoma?
Pilomyxoid astrocytomas are an uncommon and aggressive variant of pilocytic astrocytoma with unique clinical and histopathologic characteristics. Pilomyxoid astrocytomas are usually encountered in young children and infants (mean age of 10-18 months), however, adults cases have been described 3,4.

How do you get rid of pilocytic astrocytoma?
The standard treatment for PA is surgery to remove the tumor, when possible. If all of the tumor is removed, the outlook is usually good. If the tumor is in a spot where it can't be fully removed during surgery, adults and older children might get radiation therapy to help kill any tumor cells left in the area.
What grade is a pilocytic astrocytoma?
Pilocytic astrocytomas are a specific type of astrocytoma, and also belong to the broader category of gliomas – tumors that arise from glial cells. This is because astrocytes are a type of glial cell. For this reason, pilocytic astrocytomas (grade I) may also be called a “low-grade glioma.”

Is grade 3 astrocytoma a terminal?
Grade 1 and grade 2 astrocytomas grow slowly and are benign, meaning they're not cancerous. Grade 3 and grade 4 astrocytomas grow faster and are malignant, which means they're cancerous. An anaplastic astrocytoma is a grade 3 astrocytoma. While they're rare, they can be very serious if left untreated.

How to diagnose astrocytoma?
Tests and procedures used to diagnose astrocytoma include: 1 Neurological exam. During a neurological exam, your doctor will ask you about your signs and symptoms. He or she may check your vision, hearing, balance, coordination, strength and reflexes. Problems in one or more of these areas may provide clues about the part of your brain that could be affected by a brain tumor. 2 Imaging tests. Imaging tests can help your doctor determine the location and size of your brain tumor. MRI is often used to diagnose brain tumors, and it may be used along with specialized MRI imaging, such as functional MRI, perfusion MRI and magnetic resonance spectroscopy.#N#Other imaging tests may include CT and positron emission tomography (PET). 3 Removing a sample of tissue for testing (biopsy). A biopsy can be done with a needle before surgery or during surgery to remove your astrocytoma, depending on your particular situation and the location of your tumor. The sample of suspicious tissue is analyzed in a laboratory to determine the types of cells and their level of aggressiveness.#N#Specialized tests of the tumor cells can tell your doctor the types of mutations the cells have acquired. This gives your doctor clues about your prognosis and may guide your treatment options.

Specialized tests of the tumor cells can tell your doctor the types of mutations the cells have acquired. This gives your doctor clues about your prognosis and may guide your treatment options.
Can astrocytoma cause weakness?
Astrocytomas that occur in the spinal cord can cause weakness and disability in the area affected by the growing tumor. Astrocytoma can be a slow-growing tumor, or it can be an aggressive cancer that grows quickly. The aggressiveness (grade) of your astrocytoma determines your prognosis and treatment options.
Can astrocytoma grow quickly?
Some astrocytomas grow very slowly and others can be aggressive cancers that grow quickly. Astrocytoma is a type of cancer that can form in the brain or spinal cord.

Juvenile vs. adult pilocytic astrocytoma. Relatively little is known about pilocytic astrocytomas in adults. Less than 25 percent of pilocytic astrocytomas occur in adults older than 20. Similar to juvenile tumors, treatment in adults typically involves surgery to remove the tumor.
How do you know if you have pilocytic astrocytoma?
Most symptoms of pilocytic astrocytoma are related to increased pressure in the brain, or increased intracranial pressure. These symptoms include: headaches that are worse in the morning. nausea. vomiting. seizures. changes in mood or personality. Other symptoms vary depending on the location and size of the tumor.
What is the cause of gliomas in the brain?
Gliomas are a result of abnormal cell division in the brain, but the exact cause of this abnormal cell division isn’t known. It’s rare for a brain tumor to be genetically inherited, but certain types of pilocytic astrocytomas, such as optic gliomas, have been associated with a genetic disorder known as neurofibromatosis type 1 (NF1).
Why is it called juvenile pilocytic astrocytoma?
Pilocytic astrocytoma gets its name because the tumor originates from star-shaped cells in the brain called astrocytes. Astrocytes are glial cells, which help to protect and sustain brain cells called neurons. Tumors that arise from glial cells are collectively referred ...

Where are glial tumors found?
A pilocytic astrocytoma is most commonly found in a part of the brain called the cerebellum. They can also occur near the brainstem, in the cerebrum, near the optic nerve, or in the hypothalamic region of the brain. The tumor is typically slow-growing and doesn’t spread. ...
What is the best treatment for brain tumors?
Chemotherapy. Chemotherapy is a strong form of chemical drug therapy that destroys rapidly growing cells. It may be needed to stop the growth of the brain tumor cells, or it may be done in conjunction with radiation to help lower the dose of radiation needed.
Where do pilomyxoid astrocytomas occur?
Pilomyxoid astrocytomas were originally reported as arising in the hypothalamus or optic chiasm, which is the most common location, however, they may also occur elsewhere within the brain, including the posterior fossa, as well as in the spinal cord 1,6 .

Which astrocytoma is more aggressive?
Compared to pilocytic astrocytomas, pilomyxoid astrocytomas have been generally thought to behave more aggressively and have a poorer prognosis, although this may be in part at least due to their predilection for the hypothalamus and optic chiasm, which makes complete resection impossible 6 .

Although it has been suggested that pilomyxoid astrocytomas should be considered WHO grade II tumors (compared to pilocytic astrocytomas which are WHO grade I), in the 2016 update to the WHO classification of CNS tumors a formal grade has not been given 6 .
How to treat a grade 1 astrocytoma?
Grade 1 astrocytomas are normally treated with surgery where possible. The aim is to remove as much of the tumour as possible. How much can be removed will depend on where the tumour is in the brain. At this point you may be told about, or may like to ask about 'biomarker testing' and 'biobanking'. Complete tumour removal.
Can you get radiotherapy after NF1?
Depending on how much of the tumour is removed, you may be put on a 'watch and wait' approach after surgery. Alternatively you may be given radiotherapy after your surgery, though doctors try to avoid this in people with the genetic condition NF1 and also in children under three years old. Occasionally chemotherapy may also be given.
Can a brain tumour be removed?
In some cases, complete removal of the tumour may not be possible. It may be located in a difficult area of the brain to operate, or near important parts of the brain where surgery could do more harm than good. In this case, the surgeon will remove as much of the tumour as they can.
