In general, cancer in children is uncommon. This means it can be hard for doctors to plan treatments unless they know what has been most effective in other children. That is why more than 60% of children with cancer are treated as part of a clinical trial. A clinical trial is a research study that tests a new approach to treatment. The “standard of care” is the best treatments known. Clinical trials may test such approaches as a new drug, a new combination of existing treatments, or new doses of current therapies. The health and safety of all children participating in clinical trials are closely monitored.
To take advantage of these newer treatments, children with cancer should be treated at a specialized cancer center. Doctors at these centers have extensive experience in treating children with cancer and have access to the latest research. A doctor who specializes in treating children with cancer is called a pediatric oncologist. If a pediatric cancer center is not nearby, general cancer centers sometimes have pediatric specialists who are able to be part of your child’s care.
In many cases, a team of doctors works with a child and the family to provide care. This is called a multidisciplinary team. Pediatric cancer centers often have extra support services for children and their families, such as child life specialists, dietitians, physical and occupational therapists, social workers, and counselors. Special activities and programs to help your child and family cope may also be available.
Several types of therapies are used for retinoblastoma, and more than 90% of children can be cured. In addition to curing the retinoblastoma, an important goal of treatment is the preservation of vision. Many of these treatment approaches described below have become available as a result of clinical trials. The Children’s Oncology Group has recently developed clinical trials about treatment for retinoblastoma.
Descriptions of the common types of treatments used for retinoblastoma are listed below. Your child's care plan also includes treatment for symptoms and side effects, an important part of cancer care.
Treatment options and recommendations depend on several factors, including the type and stage of cancer, possible side effects, the family’s preferences, and patient’s overall health. Take time to learn about all of your child’s treatment options and be sure to ask questions about things that are unclear. Talk with your child’s doctor about the goals of each treatment and what your child can expect while receiving the treatment. Learn more about making treatment decisions.
Surgery is the removal of the tumor and some surrounding healthy tissue during an operation. Surgery to remove the eye is called enucleation. Children with a tumor in 1 eye only can often be cured with this treatment. For children with a tumor in both eyes, enucleation is used only if the ocular oncologist (a doctor who specializes in eye cancer) determines that preserving vision using other types of treatment is not possible. Surgical treatment for retinoblastoma should be performed by a specially trained pediatric ophthalmologist. Talk with your surgeon about the recovery and side effects for the surgery your child is having. Learn more about the basics of cancer surgery.
If enucleation is the best treatment to cure the cancer, there will be some loss of eyesight. This may result in trouble with depth perception, but most children adapt well to these differences over time. Talk with your child's doctor about what to expect if enucleation is recommended and what support services are available to help adapt to these visual change.
Many people worry about what their child will look like when they have an eye removed. The cosmetic surgery available today usually has good cosmetic results. To fill the area left by the missing eye, the person is fitted for an artificial eye, called a prosthesis. The prosthesis will look and behave almost the same as a natural eye. For example, the artificial eye will move along with the person’s remaining eye, just not as much as a natural eye moves. Family members may be able to tell that the eye is not real, but it is unlikely that strangers will know. If enucleation is required, talk with your child's doctor about a prosthesis; it may take many weeks for patients to receive the prosthesis.
Before surgery, talk with your health care team about the possible side effects from the specific surgery you will have.
Radiation therapy is the use of high-energy x-rays or other particles to destroy cancer cells. A doctor who specializes in giving radiation therapy to treat cancer is called a radiation oncologist. The most common type of radiation treatment is called external-beam radiation therapy, which is radiation therapy given from a machine outside the body. Proton beam radiation therapy is a more precise way of delivering radiation therapy, which could decrease both the severity and frequency of short and long-term side effects. Only a few centers can offer this type of radiation therapy. Talk with your child's doctor about its availability and whether it is recommended for your child.
Radioactive plaque therapy, also called internal radiation therapy or brachytherapy, is the delivery of radiation therapy directly to the eye with a disc containing radiation. A radiation therapy regimen, or schedule, usually consists of a specific number of treatments given over a set period of time.
Fatigue, drowsiness, nausea, vomiting, and headache are common side effects of radiation therapy, and these usually go away after treatment. Radiation therapy in young children can interfere with the body’s normal development, including growth of the bones around the eye, depending on the dose. The increased risk of additional tumors later in life for children with the hereditary form of retinoblastoma is further increased after external-beam radiation therapy. These effects are not seen after radioactive plaque therapy. Learn more about the basics of radiation therapy.
Cryosurgery, also called cryotherapy or cryoablation, uses liquid nitrogen to freeze and kill cells. More than one freezing may be needed.
Laser therapy uses heat in the form of a laser to shrink a smaller tumor. It may be called thermotherapy or "TTT" for transpupillary thermotherapy. It may be used alone or in addition to cryotherapy or radiation therapy. Photocoagulation is a different type of laser therapy that uses light to shrink tumors.
Chemotherapy is the use of drugs to destroy cancer cells, usually by ending the cancer cells’ ability to grow and divide and may be used to shrink an eye tumor. Chemotherapy is given by a pediatric oncologist or a medical oncologist, a doctor who specializes in treating cancer with medication. A chemotherapy regimen, or schedule, usually consists of a specific number of cycles given over a set period of time.
Systemic chemotherapy gets into the bloodstream to reach cancer cells throughout the body. Common ways to give chemotherapy include an intravenous (IV) tube placed into a vein using a needle or in a pill or capsule that is swallowed (orally).
Chemotherapy often makes it possible to completely get rid of any remaining smaller tumors with the following focal (localized) measures, outlined above:
Chemoreduction uses chemotherapy to reduce the size of the tumor. This is a treatment approach that is often used for children with retinoblastoma in both eyes in the hope of avoiding enucleation and preserving vision in at least 1 eye. The ophthalmologist, working closely with the pediatric oncologist, will determine if this treatment is appropriate.
Children with low-risk disease and some children with intermediate-risk disease may be able to avoid chemotherapy after surgery or reduce the intensity of chemotherapy. Talk with the doctor about whether this approach is appropriate for your child. Both doctors will regularly monitor how well the treatment is working and may recommend additional treatment to prevent the cancer from returning.
The drugs used most often for retinoblastoma are vincristine (Oncovin, Vincasar PFS), carboplatin (Paraplatin), and etoposide (Toposar, VePesid). Depending on the extent of the tumor, a combination of 2 or more drugs may be recommended. All chemotherapy has side effects that occur during treatment. Some drugs may also cause specific long-term side effects. Talk with your child's doctor about the specific drugs used and the possible short-term and long-term side effects before treatment begins.
Chemotherapy may also be delivered through the blood vessel (called intra-arterial) feeding the eye and the tumor by inserting a catheter in the child’s groin area. The doctor moves the catheter with the help of imaging technology to reach the blood vessel in the head. This procedure may be used in an effort to save the eye in children with advanced disease if the tumor is still confined to the eye. This method of giving chemotherapy with 1 or several drugs is being used both in children with 1 affected eye or both affected eyes. This method is performed by an interventional radiologist.
Another technique that may be used involves a direct injection of chemotherapy drug into the eye. This is called intravitreal injection. This method is effective in treating vitreous seeds, which are found in the fluid inside the eye. Vitreous seeds are difficult to treat with systemic chemotherapy alone.

Bone marrow transplantation/stem cell transplantation
For some children with Stage IV extraocular retinoblastoma, a bone marrow transplant may be recommended. The child is first treated with high doses of chemotherapy (and/or radiation therapy) to destroy as many cancer cells as possible, then the transplantation takes place. A stem cell transplant is a medical procedure in which healthy, highly specialized cells, called hematopoietic stem cells, are given to a patient, either to replace bone marrow that contains cancer or to help the patient’s bone marrow recover after other cancer treatment.
Hematopoietic stem cells are blood-forming cells found both in the bloodstream and in the bone marrow. Today, this procedure is more commonly called a stem cell transplant, rather than bone marrow transplant, because it is the stem cells in the blood that are typically being transplanted, not the actual bone marrow tissue.
Before recommending transplantation, doctors will talk with the patient about the risks of this treatment. They will also consider several other factors, such as results of any previous treatment and the patient’s age and general health. Side effects depend on the type of transplant, your child’s general health, and other factors. Learn more about the basics of stem cell and bone marrow transplantation.
Care for symptoms and side effects
Cancer and its treatment often cause side effects. In addition to treatments intended to slow, stop, or eliminate the cancer, an important part of cancer care is relieving a person’s symptoms and side effects. This approach is called palliative or supportive care, and it includes supporting the patient with his or her physical, emotional, and social needs.
Palliative care is any treatment that focuses on reducing symptoms, improving quality of life, and supporting patients and their families. Any person, regardless of age or type and stage of cancer, may receive palliative care. It works best when palliative care is started as early as needed in the cancer treatment process. People often receive treatment for the cancer and at the same time that they receive treatment to ease side effects. In fact, people who receive both at the same time often have less severe symptoms, better quality of life, and report they are more satisfied with treatment.
Palliative treatments vary widely and often include medication, nutritional changes, relaxation techniques, emotional support, and other therapies. Your child may also receive palliative treatments similar to those meant to eliminate the cancer, such as chemotherapy, surgery, or radiation therapy. Talk with your child’s doctor about the goals of each treatment in the treatment plan.
Before treatment begins, talk with your child’s health care team about the possible side effects of the specific treatment plan and palliative care options. During and after treatment, be sure to tell your child’s doctor or another health care team member if your child is experiencing a problem so it can be addressed as quickly as possible. Learn more about palliative care.
Remission and the chance of recurrence
A remission is when cancer cannot be detected in the body and there are no symptoms. This may also be called having “no evidence of disease” or NED.
A remission may be temporary or permanent. This uncertainty causes many people to worry that the cancer will come back. Although many remissions are permanent, it is important to talk with your child’s doctor about the possibility of the cancer returning. Understanding your child’s risk of recurrence and the treatment options may help you and your child feel more prepared if the cancer does return. Learn more about coping with the fear of recurrence.
If the cancer returns after the original treatment, it is called recurrent cancer. It may come back in the same place (called a local recurrence), nearby (regional recurrence), or in another place (distant recurrence).
When this occurs, a new cycle of testing will begin again to learn as much as possible about the recurrence. After this testing is done, you and your child’s doctor will talk about your treatment options. If retinoblastoma returns after treatment, the treatment plan depends on where the cancer recurred and how aggressive the new tumor is. The doctor may recommend surgery, radiation therapy, chemotherapy, and/or focal measures, such as photocoagulation, thermotherapy, or cryotherapy (see above). The doctor may suggest clinical trials that are studying new ways to treat this type of recurrent cancer. Whichever treatment plan you choose, palliative care will be important for relieving symptoms and side effects.
People with recurrent cancer and their families often experience emotions such as disbelief or fear. Parents are encouraged to talk with their health care team about these feelings and ask about support services to help them cope. Learn more about dealing with cancer recurrence.
If treatment does not work
Although treatment is successful for the majority of children with retinoblastoma, sometimes it is not. If a child’s cancer cannot be cured or controlled, this is called advanced or terminal cancer. This diagnosis is stressful, and advanced cancer may be difficult to discuss. However, it is important to have open and honest conversations with your child’s health care team to express your family’s feelings, preferences, and concerns. The health care team is there to help, and many team members have special skills, experience, and knowledge to support patients and their families.
Hospice care is designed to provide the best possible quality of life for people who are expected to live less than 6 months. Parents or guardians are encouraged to talk with the health care team about hospice options, which include hospice care at home, a special hospice center, or other health care locations. Nursing care and special equipment can make staying at home a workable option for many families. Some children may be happier if they can arrange to attend school part-time or keep up other activities and social connections. The child’s health care team can help parents or guardians decide on an appropriate level of activity. Making sure a child is physically comfortable and free from pain is extremely important as part of end-of-life care. Learn more about caring for a terminally ill child and advanced cancer care planning.
The death of a child is an enormous tragedy, and families may need support to help them cope with the loss. Pediatric cancer centers often have professional staff and support groups to help with the process of grieving. Learn more on grieving the loss of a child.
