The cancer is caused by a change in a gene. It may be a gene passed down from parents (inherited). Or it may be a gene change that happens by chance (sporadic).
In 1 out of 3 children with retinoblastoma, it’s present at birth (congenital). Of these children, 1 out of 4 has a form passed on from parents. It usually affects both eyes. It also increases the risk of other cancers such as sarcoma and melanoma.
In 2 out of 3 children with retinoblastoma, it occurs by chance. In these cases, it affects only one eye. There is not an increased risk of other cancers.
Symptoms may affect one or both eyes. Symptoms can occur a bit differently in each child. They can include:
Less common symptoms may include:
Most of the time, retinoblastoma has not spread (metastasized) to other areas of the body when it’s diagnosed. If it has spread, other symptoms may include:
The symptoms of retinoblastoma can be like other health conditions. Make sure your child sees a healthcare provider for a diagnosis.
Your child's healthcare provider will ask about your child's health history and symptoms. He or she will examine your child and pay close attention to the eyes. The healthcare provider will likely advise that your child see an eye specialist (ophthalmologist).
The ophthalmologist will check your child's eyes with special tools. Your child may need a dilated indirect ophthalmoscopic exam. Your child may be given anesthesia medicine to sleep through the exam.
Your child may need other tests such as:
A child may be diagnosed with no symptoms. This may be the case if you have a family history of retinoblastoma. Your child may have eye exams often to check for signs of the cancer.
Part of diagnosing cancer is called staging. Staging is the process of seeing if the cancer has spread, and where it has spread. Staging also helps to decide the treatment. There are different ways of staging cancer. Retinoblastoma tumors are staged in 5 groups lettered A through E. The groups are based on how likely it is that the eye will be saved. Talk with your child's healthcare provider about the stage of your child's cancer and what it means.
Most children in the U.S. with retinoblastoma have very good prognoses. This means they have a good chance of recovery.
Your child will be treated by a team of different types of healthcare providers, such as:
Specific treatment for retinoblastoma will be determined by your child's healthcare providers based on:
Many of the treatment methods require sleep medicine (anesthesia). Treatment may include the following:
With any cancer, how well a child is expected to recover (prognosis) varies. Keep in mind:
A child may have complications from the cancer or from treatment, such as:
You can help your child manage his or her treatment in many ways. For example:
A child with retinoblastoma needs ongoing care. Your child will be cared for by a team of healthcare providers. They will treat any late effects of treatment and to watch for signs or symptoms of the tumor growing back. The healthcare providers will also check your child with imaging tests and other tests.
If your child has an implant and artificial eye, he or she should wear protective eyewear during activities that may harm the eye.
Family members may want to see a genetic counselor to learn more about the risk of retinoblastoma.
Call the healthcare provider if your child has:
