As a tumor of the central nervous system, oligodendroglioma affects the brain (and in rare cases, the spinal cord). It begins in a particular kind of glial cell, which supports the nervous system. Even when oligodendroglioma is malignant, experts believe it is a fairly curable tumor with generally good survival rates.
Depending on where the tumor is located in the brain, your parents may have symptoms like seizures, headaches, difficulty speaking, weakness or numbness on one side of the body, balance problems, and difficulty thinking and remembering things.
Oligodendrogliomas, like many brain tumors, frequently don't show any symptoms until they start to disrupt the surrounding brain tissue. Seizures or headaches are the most typical symptoms. Approximately 80% of patients with oligodendroglioma will experience a seizure as a result of the cancer. This is due to the fact that oligodendrogliomas frequently impact the cerebral cortex, the wrinkled outer layer of the brain. The brain regions that govern many of your daily skills, including vision, language, muscular control, and more, are located in the cortex. Other symptoms include:
CausesAll oligodendrogliomas are caused by two distinct DNA alterations, by definition:
1p/19q co-deletion: Cells employ their chromosomes, which are compacted DNA "data," as a guide. Errors can occasionally occur during chromosomal copying during cell division. The long (q) arm of chromosome 19 and the short (p) arm of chromosome 1 are always deleted in oligodendrogliomas. This is frequently referred to by experts as a "1p/19q co-deletion."
Mutations in IDH1 or IDH2: Sections of your DNA that contain particular instructions are called genes. One of them instructs your body on how to produce isocitrate dehydrogenase (IDH), an enzyme that aids in specific metabolic processes. Oligodendrogliomas can result from any of the two IDH mutations, IDH1 or IDH2.
Risk FactorsThere are currently no known risk factors for oligodendroglioma. However, some research suggests that prior radiation therapy, such as that used to treat other cancers, may be a risk factor for the development of gliomas, which are related tumors. To determine whether something could be a cause or contributing factor, more investigation is required.
ComplicationsBecause oligodendrogliomas impact the brain, they may result in a variety of issues. The location of the oligodendroglioma, along with any other medical disorders one may have, will determine the complications patient may have.
Among the issues to be mindful of are:
Malignant transformation: Low-grade, non-cancerous oligodendrogliomas can occasionally "transform." This indicates that the tumor cells develop into malignant ones over time.
Strokes or other issues related to the circulatory system: As an oligodendroglioma grows inside your skull or brain, it will displace the surrounding brain tissue as it takes up more and more room. Strokes or stroke-like events may result from that.
Changes in skull structure: Oligodendrogliomas frequently become calcified, or hardened, as a result of calcium buildup. The skull bone may begin to be impacted when that occurs on the outside of your brain. An oligodendroglioma that grows slowly may also induce changes or shifts in the surrounding bone tissue.
The use of genomic research to our present standard of care for brain tumors, including sophisticated next-generation sequencing (NGS) to decode their genomic properties, was made possible by technological advancements throughout the past ten years. As a result, patients might get comprehensive NGS panel findings that list a number of mutations linked to tumors. Despite a lot of progress, we still don't fully grasp the therapeutic implications of those mutations or how a particular genetic profile influences the prognosis for a given patient. This is particularly true with oligodendrogliomas, where a 10- to 20-year follow-up may be necessary to determine the effect on prognosis.
The causes and risk factors for oligodendrogliomas are unknown to experts. As a result, there is no method to avoid it or lower your chance of developing it.
Chemotherapy : Oligodendroglioma can be effectively treated with some chemotherapeutic medications. The following are the most likely chemotherapy treatments.
Cost Start From USD 600 - USD 700Explore Options
Radiation treatment: Oligodendroglioma is frequently treated with radiation therapy. With this method, tumor cells are subjected to enough energy to be destroyed. The radiation is aimed as accurately as it can be.
A medical professional will use a variety of techniques to diagnose oligodendroglioma, such as:
Because diagnostic imaging allows medical professionals to "see" within your skull, it is particularly crucial when oligodendrogliomas are present. The following scans are the most likely to be helpful:
Computed tomography (CT) scans: Following a seizure or other focused symptoms, these are frequently the initial imaging tests performed. Because they contain calcium, your bones appear bright on CT and X-ray images. Because oligodendrogliomas frequently include calcium, they frequently exhibit a brilliant appearance.
The many structures inside your head can be readily seen on magnetic resonance imaging (MRI) images. They can assist in pinpointing the exact location and size of an oligodendroglioma.
However, an oligodendroglioma cannot be diagnosed using imaging scans alone. They merely offer proof that you have a brain tumor that may be an oligodendroglioma. Providers use that evidence to decide if you require pathology testing and a brain biopsy.
Treatment for oligodendroglioma can damage brain regions involved in motor control and cognitive function. You may require assistance to regain your mobility, speech, vision, and cognitive function following therapy.
School-age children can benefit from tutoring to help them deal with memory and cognitive changes following a brain tumor.
If your oligodendroglioma is causing symptoms, you might need medicine to make you more comfortable. Which medications you need depends on your situation. Options might include:
Medicine to help with thinking and memory problems.

Although they are not strictly "curable," oligodendrogliomas are treatable malignancies. The most common treatment for oligodendroglioma is to remove the entire tumor, or as much of it as feasible. Your care team will next assess if chemotherapy, radiation therapy, or a combination of these treatments are required to eliminate any cancer cells that may still be present.
With skilled neurosurgeons, oncologists and cutting-edge medical technology, India has demonstrated significant success rates in treating oligodendrogliomas. The nation's healthcare institutions offer top-notch treatment alternatives, guaranteeing successful outcomes for many patients.
Yes, many Indian hospitals offer the following for oligodendrogliomas treatment:
How can I choose India's top doctor and the best oligodendroglioma treatment hospital?
Always consider the following factors when selecting Indian hospitals:
In general, oligodendroglioma treatment has much improved in India. For oligodendroglioma, the relative five-year survival rate is 79.5%. The prognosis is influenced by numerous circumstances, though. These include the patient's age and health at diagnosis, the tumor grade and molecular type, and the response to treatment. The five-year survival rate is higher for younger adults. High-grade oligodendroglioma has a five-year survival rate of 45% to 76%.
Oligodendroglioma is a severe worry because it is a sort of brain tumor. However, compared to other forms of gliomas, it is less harmful and more curable. The majority of people are unaware that they have oligodendroglioma until they experience symptoms, particularly headaches or seizures. Emergency medical attention is always required for a first seizure. When a headache occurs frequently, during specific activities, or in a way that interferes with your parent’s life, you should seek medical assistance.
An imaging examination that initially finds an oligodendroglioma is typically the result of symptoms. Once identified, a medical professional will suggest tests to identify the condition and decide on a course of treatment. Oligodendroglioma must be treated because even benign, low-grade tumors have the potential to develop into malignancy. One important strategy to stop oligodendroglioma from getting worse or spreading to other areas of your body is to stop its spread.
The survival of patients with oligodendroglial tumors is considerably increased by oncological treatment. It is yet unknown, though, how harmful it might be to long-term survivors' cognitive function. After more than five years of treatment completion, our study revealed that patients with WHO grades II and III oligodendroglial tumors exhibit cognitive impairment, which can be severe in up to 38% of cases. This is accompanied by structural GM and WM damage, underscoring the need for future strategies in patients with long expected survival.
Your healthcare practitioner will assist you in selecting the best course of treatment for your parents if they have oligodendroglioma. Additionally, they will suggest a course of therapy and frequent follow-up appointments.
It's crucial to take them to follow-up appointments and therapies. It's also critical to ensure they receive treatment on a regular basis and according to prescriptions.
Many of the treatments for oligodendroglioma have side effects. They can learn about the potential side effects that are most likely to occur and what you can do to mitigate them from your healthcare professional.
