Oh, do you or your child sometimes have a headache that keeps coming back? Or do you vomit all the time? The reason for this may be something you don't even think about. Today we are going to talk about a condition that seems a little serious, but is often very treatable. It is a type of brain tumor called (Pilocytic Astrocytoma) . The name sounds a little scary, doesn't it? But don't worry, let's talk about it in detail.
What is this (Pilocytic Astrocytoma)?
Simply put, Pilocytic Astrocytoma is a tumor that develops in the brain. Our brains contain a type of cell called astrocytes . These are star-shaped cells. Their main function is to help the nerve cells in our brain, the neurons that carry messages, to function properly. So, a tumor called Pilocytic Astrocytoma develops from these astrocytes.
The World Health Organization classifies these tumors as Grade I , which means they are nonmalignant . Grade I means that when viewed under a microscope, the cells in the tumor look like normal cells, not cancer cells. They also grow very slowly . They usually do not spread to other parts of the body. However, they can grow slightly in size. In most cases, surgery to remove the tumor can cure the disease.
How common is this situation?
Pilocytic Astrocytoma is the most common type of brain tumor in children . In the United States alone, it is estimated that this condition affects about one in 100,000 children under the age of 20. This type accounts for about 15% of all brain tumors in children. In adults, it is slightly less common, accounting for about 5% of all brain tumors.
What are the symptoms of Pilocytic Astrocytoma?
The symptoms of Pilocytic Astrocytoma can vary from person to person. It mainly depends on the size of the tumor and its exact location in the brain . Sometimes, the tumor may not show any symptoms until it is large. However, there are some common symptoms that can be seen:
- Frequent headaches .
- Fatigue, or constant sleepiness (Lethargy) .
- Vomiting .
- Changes in behavior, personality, and mood . You may become more stubborn and angry than before.
- Changes in the ability to think, learn, and concentrate .
- Stiff neck .
- Blurred vision, double vision, or rapid eye movement .
- Weakness in the limbs and difficulty with coordination when walking or doing tasks .
- Precocious puberty (early puberty) due to hormonal changes .
Seizures can occur rarely, but they are not very common.
Where do these (Pilocytic Astrocytoma) tumors form?
Most of the time, these tumors (Pilocytic Astrocytoma) develop in our central nervous system , which is the brain and spinal cord. They are most commonly found in a part called the cerebellum . The cerebellum is the part of our brain at the back, bottom, where the head and neck meet.
Apart from that, these tumors can also develop in the following places, albeit to a lesser extent:
- Optic nerve - The nerve that connects our eyes to our vision.
- Hypothalamus - An important part of the brain that controls hormones.
- Brainstem - The part that connects the brain to the spinal cord.
- Spinal cord .
What causes this?
In fact, we still don't know exactly what causes these astrocyte cells to suddenly grow out of control and form a tumor. However, research has found several factors that may contribute to this:
- Genetic changes : Certain changes in the gene (BRAF) have been found to be associated with this.
- Exposure to ionizing radiation : When receiving radiation therapy as a treatment for other types of cancer, for example, leukemia or lymphoma.
In addition, Pilocytic Astrocytoma can also be seen with certain genetic conditions . Examples:
- (Neurofibromatosis Type 1)
- (Li-Fraumeni syndrome)
- (Tuberous sclerosis)
What complications can this cause?
Some complications can occur due to Pilocytic Astrocytoma. These include:
- Loss of vision .
- Bulging eyes .
- Weight loss or gain .
In very rare and severe cases, the location and size of the tumor can cause pressure on the brainstem (brainstem compression) or a condition called hydrocephalus, which can be life-threatening.
How is this disease (Pilocytic Astrocytoma) diagnosed?
A doctor will first diagnose you or your child by physically examining them, listening carefully to your symptoms, and taking your medical history . They will then perform tests to rule out other conditions that may cause similar symptoms.
Scans (Radiology) to diagnose Pilocytic Astrocytoma
Most often, this tumor is found and diagnosed with a scan called (MRI - Magnetic Resonance Imaging) . Sometimes, young children with symptoms of the nervous system have difficulty staying still during the scan (MRI). In such cases, doctors recommend a (CT scan - Computed Tomography scan) . These scans can determine the size, shape, and location of the tumor. This is very helpful in planning treatment.
What are the treatments for Pilocytic Astrocytoma?
The main treatment recommended by doctors for Pilocytic Astrocytoma is surgery to remove the tumor . In most cases, if the tumor can be completely removed in this way, the Pilocytic Astrocytoma condition can be completely cured.
However, sometimes the size and location of the tumor make it difficult to remove it completely. If there is a high risk of complications, the surgeon may remove only part of the tumor and monitor the size and growth of the remaining part over time. If the tumor recurs or the remaining part grows again, another operation may be performed.
Another less common treatment option is radiation therapy . Your doctor may choose this treatment based on the location of the tumor, the difficulty of surgery, or whether you have other chemotherapy options. Your doctor will decide which treatment is best for you.
Importantly, with the advancements in genetic testing , including molecular testing for Pilocytic Astrocytoma, post-surgery testing can identify some of the mutations that cause symptoms, such as BRAF v600E. There are FDA-approved treatments for these mutations. You may also be eligible for experimental therapies or clinical trials . These may be beneficial for you and others. So, talk to your doctor about having these molecular tests done on your tumor tissue after surgery.
Are there any side effects of the treatment?
Some side effects may occur after surgery to remove the Pilocytic Astrocytoma tumor. For example:
- Bleeding .
- Infection .
- Swelling .
- Pain .
- Headache .
- Hydrocephalus .
Your surgeon will discuss these side effects with you before starting treatment, and they will take great care to prevent these side effects or complications from occurring during the surgery.
Radiation therapy can also cause some side effects:
- Tired .
- Nausea and vomiting .
- Diarrhea .
- Headache .
- Hair loss .
- Skin allergies, redness .
- Food is tasteless .
- Frequent urination or the need to urinate quickly .
How quickly will I recover after treatment?
(Pilocytic Astrocytoma) It may take several weeks for your body to heal after surgery to remove the tumor. Your doctor will give you instructions on how to care for yourself or your child after surgery. If you have any questions, ask your doctor.
What is the prognosis for this condition?
For a Grade I (Pilocytic Astrocytoma), the prognosis is very good . This is because it is a nonmalignant tumor and does not usually spread to other parts of the body. The sooner the tumor is found and treated, the better the chance of a cure . Also, your general health, age, and other factors will affect the diagnosis. Depending on your condition, your doctor can give you a more accurate diagnosis.
What is the survival rate for (Pilocytic Astrocytoma)?
Life expectancy for children and young adults diagnosed with Pilocytic Astrocytoma before the age of 20 is very high . One study found that the 10-year survival rate is more than 92%. This rate increases if surgeons can completely remove the tumor.
Can Pilocytic Astrocytoma be prevented?
Because researchers still do not have a clear understanding of the causes of these tumors, there is currently no way to prevent them .
When should you see a doctor?
If you think you or your child has symptoms of Pilocytic Astrocytoma, see a doctor immediately. Especially:
- Frequent headaches .
- Changes in vision .
- Behavioral changes .
- Loss of body control, difficulty in coordination .
Also, tell your doctor if you notice any of the following after surgery to remove the tumor:
- Severe pain .
- Swelling .
- Skin discoloration at the surgery site .
If you feel like something is wrong, talk to a doctor.
What questions should you ask the doctor?
Don't forget to ask these questions when you see your doctor:
- Do I really need surgery?
- What are the side effects of the treatment?
- How should I (or my child) take care of myself after surgery?
- What complications should I watch out for after surgery?
- What are my recovery prospects?
- Are there any clinical trials that are relevant to my condition?
Finally, things to remember
It's normal to feel scared and sad when you learn that you, your child, or someone you love has a brain tumor. But Pilocytic Astrocytoma is a condition that can often be treated and cured . It usually doesn't spread to other parts of the body, and it can be completely cured if the tumor is removed.
Your medical team will help you find the best treatment plan for you. They will also do their best to prevent complications and help you recover quickly. So take heart!
