                    There are different types of treatment for patients with retinoblastoma.
                    Different types of treatment are available for patients with retinoblastoma. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment.    Because cancer in children is rare, taking part in a clinical trial should be considered. Some clinical trials are open only to patients who have not started treatment.
                
                
                    Children with retinoblastoma should have their treatment planned by a team of health care providers who are experts in treating cancer in children.
                    The goals of treatment are to save the child's life, to save vision and the eye, and to prevent serious side effects. Treatment will be overseen by a pediatric oncologist, a doctor who specializes in treating children with cancer. The pediatric oncologist works with other health care providers who are experts in treating children with eye cancer and who specialize in certain areas of medicine. These may include a pediatric ophthalmologist (children's eye doctor) who has a lot of experience in treating retinoblastoma and the following specialists:         -  Pediatric surgeon.    -  Radiation oncologist.    -  Pediatrician.    -  Pediatric nurse specialist.    -  Rehabilitation specialist.    -  Social worker.    -  Geneticist or genetic counselor.
                
                
                    Treatment for retinoblastoma may cause side effects.
                    For information about side effects that begin during treatment for cancer, see our Side Effects page.   Side effects from cancer treatment that begin after treatment and continue for months or years are called late effects. Late effects of treatment for retinoblastoma may include the following:          - Physical problems such as seeing or hearing problems or, if the eye is removed, a change in the shape and size of the bone around the eye.     - Changes in mood, feelings, thinking, learning, or memory.     -  Second cancers (new types of cancer), such as lung and bladder cancers, osteosarcoma, soft tissue sarcoma, or melanoma.         The following risk factors may increase the risk of having another cancer:         - Having the heritable form of retinoblastoma.    - Past treatment with radiation therapy, especially before age 1 year.    - Having already had a previous second cancer.        It is important to talk with your child's doctors about the effects cancer treatment can have on your child. Regular follow-up by health professionals who are experts in diagnosing and treating late effects is important. See the PDQ summary on Late Effects of Treatment for Childhood Cancer for more information.
                
                
                    Six types of standard treatment are used:
                    Cryotherapy     Cryotherapy is a treatment that uses an instrument to freeze and destroy abnormal tissue. This type of treatment is also called cryosurgery.       Thermotherapy     Thermotherapy is the use of heat to destroy cancer cells. Thermotherapy may be given using a laser beam aimed through the dilated pupil or onto the outside of the eyeball. Thermotherapy may be used alone for small tumors or combined with chemotherapy for larger tumors. This treatment is a type of laser therapy.       Chemotherapy     Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. The way the chemotherapy is given depends on the stage of the cancer and where the cancer is in the body.    There are different types of chemotherapy:            -  Systemic chemotherapy: When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body. Systemic chemotherapy is given to shrink the tumor (chemoreduction) and avoid surgery to remove the eye. After chemoreduction, other treatments may include radiation therapy, cryotherapy, laser therapy, or regional chemotherapy.  Systemic chemotherapy may also be given to kill any cancer cells that are left after the initial treatment or to patients with retinoblastoma that occurs outside the eye. Treatment given after the initial treatment, to lower the risk that the cancer will come back, is called adjuvant therapy.     - Regional chemotherapy: When chemotherapy is placed directly into the cerebrospinal fluid (intrathecal chemotherapy), an organ (such as the eye), or a body cavity, the drugs mainly affect cancer cells in those areas. Several types of regional chemotherapy are used to treat retinoblastoma.                  -  Ophthalmic artery infusion chemotherapy: Ophthalmic artery infusion chemotherapy carries anticancer drugs directly to the eye. A catheter is put into an artery that leads to the eye and the anticancer drug is given through the catheter. After the drug is given, a small balloon may be inserted into the artery to block it and keep most of the anticancer drug trapped near the tumor. This type of chemotherapy may be given as the initial treatment when the tumor is in the eye only or when the tumor has not responded to other types of treatment. Ophthalmic artery infusion chemotherapy is given at special retinoblastoma treatment centers.        -  Intravitreal chemotherapy: Intravitreal chemotherapy is the injection of anticancer drugs directly into the vitreous humor (jelly-like substance) inside in the eye. It is used to treat cancer that has spread to the vitreous humor and has not responded to treatment or has come back after treatment.                       See Drugs Approved for Retinoblastoma for more information.       Radiation therapy    Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy:             -  External-beam radiation therapy uses a machine outside the body to send radiation toward the cancer. Certain ways of giving radiation therapy can help keep radiation from damaging nearby healthy tissue. These types of radiation therapy include the following:                  -  Intensity-modulated radiation therapy (IMRT): IMRT is a type of 3-dimensional (3-D) external radiation therapy that uses a computer to make pictures of the size and shape of the tumor. Thin beams of radiation of different intensities (strengths) are aimed at the tumor from many angles.       -  Proton-beam radiation therapy: Proton-beam therapy is a type of high-energy, external radiation therapy. A radiation therapy machine aims streams of protons (tiny, invisible, positively-charged particles) at the cancer cells to kill them.                -  Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. Certain ways of giving radiation therapy can help keep radiation from damaging nearby healthy tissue. This type of internal radiation therapy may include the following:                  -  Plaque radiotherapy: Radioactive seeds are attached to one side of a disk, called a plaque, and placed directly on the outside wall of the eye near the tumor. The side of the plaque with the seeds on it faces the eyeball, aiming radiation at the tumor. The plaque helps protect other nearby tissue from the radiation.                      The way the radiation therapy is given depends on the type and stage of the cancer being treated and how the cancer responded to other treatments. External and internal radiation therapy are used to treat retinoblastoma.       High-dose chemotherapy with stem cell rescue     High-dose chemotherapy with stem cell rescue is a way of giving high doses of chemotherapy and replacing blood -forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient and are frozen and stored. After the chemotherapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the body's blood cells.    See Drugs Approved for Retinoblastoma for more information.       Surgery (enucleation)      Enucleation is surgery to remove the eye and part of the optic nerve. A sample of the eye tissue that is removed will be checked under a microscope to see if there are any signs that the cancer is likely to spread to other parts of the body. This should be done by an experienced pathologist, who is familiar with retinoblastoma and other diseases of the eye. Enucleation is done if there is little or no chance that vision can be saved and when the tumor is large, did not respond to treatment, or comes back after treatment. The patient will be fitted for an artificial eye.    Close follow-up is needed for 2 years or more to check for signs of recurrence in the area around the affected eye and to check the other eye.
                
                
                    New types of treatment are being tested in clinical trials.
                    Information about clinical trials is available from the NCI website.
                
                
                    Patients may want to think about taking part in a clinical trial.
                    For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.   Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.   Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
                
                
                    Patients can enter clinical trials before, during, or after starting their cancer treatment.
                    Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.   Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials.
                
                
                    Follow-up tests may be needed.
                    Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests.   Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your child's condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.

		                    Treatment of Unilateral, Bilateral, and Cavitary Retinoblastoma
		                    If it is likely that the eye can be saved, treatment may include the following:         -  Systemic chemotherapy or ophthalmic artery infusion chemotherapy, with or without intravitreal chemotherapy, to shrink the tumor. This may be followed by one or more of the following:               -  Cryotherapy.       -  Thermotherapy.      -  Plaque radiotherapy.             -  External-beam radiation therapy for bilateral intraocular retinoblastoma that does not respond to other treatments.    - A clinical trial of ophthalmic artery infusion for unilateral retinoblastoma that has spread to the vitreous humor.        If the tumor is large and it is not likely that the eye can be saved, treatment may include the following:         -  Surgery (enucleation). After surgery, systemic chemotherapy may be given to lower the risk that the cancer will spread to other parts of the body.        When retinoblastoma is in both eyes, the treatment for each eye may be different, depending on the size of the tumor and whether it is likely that the eye can be saved. The dose of systemic chemotherapy is usually based on the eye that has more cancer.   Treatment for cavitary retinoblastoma, a type of intraocular retinoblastoma, may include the following:         - Systemic chemotherapy or ophthalmic artery infusion chemotherapy.

		                    Treatment of Extraocular Retinoblastoma
		                    Treatment for extraocular retinoblastoma that has spread to the area around the eye may include the following:         -  Systemic chemotherapy and external-beam radiation therapy.    - Systemic chemotherapy followed by surgery (enucleation). External-beam radiation therapy and more chemotherapy may be given after surgery.         Treatment for extraocular retinoblastoma that has spread to the brain may include the following:         - Systemic or intrathecal chemotherapy.    -  External-beam radiation therapy to the brain and spinal cord.     - Chemotherapy followed by high-dose chemotherapy with stem cell rescue.        It is not clear whether treatment with chemotherapy, radiation therapy, or high-dose chemotherapy with stem cell rescue helps patients with extraocular retinoblastoma live longer.   For trilateral retinoblastoma, treatment may include the following:         - Systemic chemotherapy followed by high-dose chemotherapy with stem cell rescue.    - Systemic chemotherapy followed by surgery and external-beam radiation therapy.        For retinoblastoma that has spread to other parts of the body, but not the brain, treatment may include the following:         - Chemotherapy followed by high-dose chemotherapy with stem cell rescue and external-beam radiation therapy.
