What is an oligodendroglioma?
Oligodendrogliomas are rare brain tumors that affect cells called oligodendrocytes, which cover and protect nerve cells. Oligodendrogliomas develop in areas of the brain called cerebral lobes, with 50 percent occurring in the frontal lobe. Oligodendrogliomas can be low (grade II) or high-grade tumors (III or IV).
How common is oligodendroglioma?
- Oligodendrogliomas account for about 4% of all primary brain tumors.
- About 6% of oligodendrogliomas occur in infants and children.
What are the symptoms of oligodendroglioma?
Many patients with oligodendrogliomas have no symptoms. The symptoms are usually directly related to the tumor’s location. The symptoms that may occur can also be related to other diseases or conditions:
- Seizures—the most common symptom
- Personality changes
How is oligodendroglioma treated?
Oligodendroglioma treatment may include the following:
- Surgery — used to remove as much of the tumor as possible. If the tumor cannot be reached for removal, biopsy alone is done.
Following surgery or biopsy, radiation therapy with or without chemotherapy may be used.
- Radiation therapy — used in addition to, or in place of other procedures, depending on the placement and severity of the tumor. Radiation therapy involves high-energy X-rays or other types of radiation to kill cancer cells or stop them from growing:
- External radiation uses machines outside the body to deliver the X-ray dose.
Oligodendrogliomas sometimes return. These patients may need more surgery, radiation therapy, chemotherapy or other investigational treatments.
- Chemotherapy (“chemo”) — uses powerful medicines to kill cancer cells or stop them from growing (dividing) and making more cancer cells:
- Chemo may be injected into the bloodstream, so that it can travel throughout the body.
- Some chemo may be given by mouth.
- Combination therapy uses more than one type of chemo at a time.
What are the survival rates for oligodendrogliomas?
- Because these tumors are rare, it is hard to provide accurate data for survival rates. When the entire tumor can be removed, the long-term survival rate in low-grade oligodendroglioma is greater than 90%.
- When the tumor cannot be removed completely and radiation therapy is used, the survival rate is about 80% to 90%.
- Low-grade oligodendrogliomas have a higher survival rate than the high grade tumors.
Why choose St. Jude for your child’s oligodendroglioma treatment?
- St. Jude has one of the largest pediatric brain tumor programs in the country.
- The St. Jude staff is dedicated to treating children who have serious illnesses. Here, you will find a hospital and staff that has only one focus—your child.
- St. Jude is committed to not only finding cures, but also helping children hold on to their quality of life. Children are not just small people. Their bodies and systems are unique, along with the disorders that affect them. For the best care, they need a specialized team. That is what you get from the St. Jude Brain Tumor Program.
- By working closely with the pediatric neurosurgeons at Le Bonheur Children’s Hospital in Memphis, the St. Jude Brain Tumor Program offers an expert team of doctors from many medical fields. The team includes: neuro-oncologists, who study and treat cancer in the brain and nervous system; neurosurgeons, who operate on the brain, skull and spinal cord; and radiation oncologists, who treat cancer with radiation. All of these doctors have devoted their careers to finding cures and providing treatment for children with brain tumors. This diverse knowledge is vital to the complete care of children with brain tumors.
- Our brain tumor doctors also work closely with support staff in nursing, rehabilitation services, neuropathology, pharmacy, neuroradiology, neuropsychology, clinical nutrition, child life and social work, along with many others. Support staff members have been specially trained to care for children with brain tumors.
- The nurse-to-patient ratio at St. Jude is unmatched— averaging 1:3 in hematology and oncology and 1:1 in the Intensive Care Unit.
- The St. Jude Brain Tumor Program has made great advances in treatments for brain tumor patients. Some of the world’s best neuroscientists, cancer biologists and doctors from the St. Jude Neurobiology and Brain Tumor Divisions combine their efforts to seek cures. In this interactive program, discoveries about the biology of both normal and harmful cell growth are rapidly tested in clinic studies. These studies include Phase I, II and III trials of the most common and deadly forms of childhood brain tumors.
- Being able to take a drug directly from the lab to your child is one of the major advantages of centers like St. Jude. Before treating a patient with any new drug, the St. Jude staff does many tests in the lab. The tests show if the drug is safe, if it works, and the best way to use it to help patients.
- St. Jude has created more clinical trials for cancer than any other children’s hospital in the United States.
- Along with the treatment studies constantly being developing at St. Jude, the staff also treats patients on studies developed by the Children’s Oncology Group, the Pediatric Brain Tumor Consortium and the Pacific Pediatric Neuro-Oncology Consortium. Many St. Jude staff members play key roles in developing these studies, which are large tests carried out at centers across the United States.
- St. Jude practices patient family-centered care. Patient family-centered care is health care that focuses on the family as a child’s primary source of strength, support and well-being. At the heart of patient family-centered care is the belief that health care staff and the family are partners, working together to best meet the needs of the child. Excellence in health care happens when we work together and honor the expertise each of us brings to every health care encounter.
- St. Jude is the only National Cancer Institute-designated Comprehensive Cancer Center devoted solely to children.
