The tumor is composed mainly of undifferentiated anaplastic cells blasts that arise from the nuclear layers of the retina. It is the most common eye tumor in children and it usually occurs before the age of five. It can occur in one eye (unilateral) or in both eyes (bilateral). About Retinoblastoma In about 40% of the cases, retinoblastoma is hereditary. In fact, retinoblastoma was one of the first cancers recognized as "hereditary". Before surgery, children who had retinoblastoma died before they reached childbearing age. When doctors in the first part of this century began removing the affected eye to treat the disease, the children survived the cancer and lived to have their own children, some of whom in turn developed retinoblastoma. In the 1970s, researchers studied the DNA of retinoblastoma carriers and found one of the first "oncogenes". They found that deletions or mutations of the "retinoblastoma" gene within the q14 band of chromosome 13 are highly associated with a predisposition to retinoblastoma.

Main Search Index Definition Description Causes ... Resources Retinoblastoma Definition Retinoblastoma is a rare childhood cancer of the eye. It is curable if detected early, but often requires surgical removal of the eye. Description Retinoblastoma is a malignant tumor which usually appears in infants or young children. It occurs at a frequency of about one in every 15,000 births. In some cases, there is a family (familial) history of the disease. The genetic cause of retinoblastoma has been extensively studied. It is described as a "two-hit" process. Normally, individuals have two good copies of the retinoblastoma gene (RB-1) on chromosome 13. The disease develops in individuals in which mutation has occurred in both copies of RB-1. It appears that about 40% of patients are born with a defective copy (first "hit"), inherited from one parent. The second copy is rendered defective by a separate mutation (second "hit") that occurs in the eye. Individuals with an inherited RB-1 defect have high likelihood of developing retinoblastoma in both eyes. For these individuals, diagnosis occurs at age one. These patients also have increased risk of developing other types of cancer. The other 60% of patients inherit two normal copies of RB-1 and develop the disease only after each copy experiences an independent mutation. The likelihood of two independent "hits" is lower, and these individuals are less likely to develop retinoblastoma in both eyes. For these individuals, average age of diagnosis is 2.1 years.

Ask the Expert Retinoblastoma Definition Symptoms Treatment Clinic Information Definition Retinoblastoma is a malignant (cancerous) tumor of the retina. The retina is the thin nerve tissue that lines the back of the eye that senses light and forms images. Although retinoblastoma may occur at any age, it most often occurs in younger children, usually before the age of five years. Retinablastoma affects one in every 18,000 births, with an estimated 250-500 cases diagnosed in the United States each year. The tumor may be in one eye only or in both eyes. Retinoblastoma is usually confined to the eye but, if left untreated, will spread to nearby tissues and other parts of the body. Retinoblastoma may be hereditary (runs in families) or nonhereditary. The hereditary form may be in one or both eyes. Most retinoblastoma occurring in only one eye is not hereditary; when the disease occurs in both eyes, it is always hereditary. Because of the hereditary factor, brothers and sisters of children with retinoblastoma warrant examination to find out if they may develop the disease. If your child has retinoblastoma, particularly the hereditary type, there is an increased chance that he or she may develop a second cancer in later years. Parents should continue taking their child for medical check-ups even after the cancer has been treated.

It is caused by a mutation in the Rb-1 protein. It occurs mostly in younger children and accounts for about 3% of the cancers occurring in children younger than 15 years. The estimated annual incidence is approximately 4 per million children The tumor may begin in one or both eyes. Retinoblastoma is usually confined to the eye but can spread to the brain via the optic nerve. Retinoblastoma may be hereditary (inherited) or nonhereditary. The hereditary form may be in one or both eyes, and generally affects younger children. Retinoblastoma occurring in only one eye is often not hereditary and is more prevalent in older children. When the disease occurs in both eyes, it is always hereditary. Because of the hereditary factor, patients and their brothers and sisters should have periodic examinations, including genetic counseling, to determine their risk for developing the disease.

Retinoblastoma What is retinoblastoma? Retinoblastoma is a rare cancer of the retina. The retina is the innermost layer of the eye, located at the back of the eye, that receives light and images necessary for vision. What causes retinoblastoma? Retinoblastoma occurs due to mutations in a tumor suppressor gene (called RB1) located on chromosome #13. Two mutations (or gene changes) are necessary to "knock-out" this gene, and cause uncontrolled cell growth. In inherited retinoblastoma (40 percent of the cases), the first mutation is inherited from a parent, while the second occurs during the development of the retina. In sporadic retinoblastoma (60 percent of the cases), both mutations occur during development of the retina. Sporadic means "occurs by chance." Alterations in the RB1 gene have also been found in other tumors, including osteosarcoma and breast cancer. Most children with inherited retinoblastoma generally have tumors involving both eyes. (In fact, all cases involving both eyes should be considered hereditary). The RB1 gene is an autosomal dominant gene, which means that both males and females are equally affected, and there is a 50/50 chance, with each pregnancy, for a parent to transmit the gene to a child. When a child inherits the gene, there is a 75 to 90 percent chance for the second mutation to occur, resulting in retinoblastoma. This means that some children who inherit the mutation may never get the second mutation, and may, therefore, never develop retinoblastoma. (They can still transmit the gene to their offspring, however, so that their children could develop the disease.)

Retinoblastoma What is retinoblastoma? Retinoblastoma is a rare cancer of the retina. The retina is the innermost layer of the eye, located at the back of the eye, that receives light and images necessary for vision. About 200 children in the US are diagnosed with this type of cancer each year. It mostly occurs in children under the age of 5; the highest incidence of the disease occurs between infancy and age 2. Both males and females are affected equally. Retinoblastoma can occur in either eye, however, in about 25 percent of the cases, the tumor is present in both eyes. Retinoblastoma cells can, in rare cases, spread (metastasize) to other areas of the body, including the bone marrow. What causes retinoblastoma?

Alternative Names: Tumor - retina; Cancer - retina Causes, incidence, and risk factors: Retinoblastoma occurs when a cell of the growing retina develops a mutation in the RB gene (a tumor suppresser gene). This mutation causes the cell to grow out of control and become cancererous. Sometimes this mutation develops in a child whose family has never had eye cancer, but other times the mutation is present in several family members. If the mutation runs in the family, there is a 50% chance that an affected person's children will also have the mutation and a high risk of developing retinoblastoma. One or both eyes may be affected. A visible whiteness in the pupil may be present.

Retinoblastoma Retinoblastoma is a rare fast-growing cancer that only occurs in newborns, infants and children under 5 years of age. Arising from immature retinal cells in one or both eyes, these tumors begin as tiny elevations in the retina and eventually fill the eye over time. Diagnosis With early diagnosis, the disease is treatable and, in most cases, the eyesight can be saved as well as the life of the child. By dilating the pupils of an infant, most cases of this disease, as well as the pathology of many other ocular diseases can be detected. Treatment Treatment protocols include chemotherapy, radiation, sequential aggressive local laser or cryotherapy, the removal of one or both eyes (enucleation), or combinations of the above. An estimated 8,000 cases occur annually worldwide. Of these, 7,000 die (mostly in developing countries) due to the delay in diagnosis or because of the lack of access to expert medical care. In the developed world, 97% of infants survive their retinoblastoma, but most have a moderate to severe visual impairment. (For more information, go to http://www.retinoblastoma.net

Retinoblastoma Dr Trisha Macnair Retinoblastoma (Rb) is a malignant tumour which develops at the back of the eye. It originates in the cells of the retina - the light sensitive part of the eye. In this article Further help This cancer may be unilateral (affecting one eye; about two thirds of children) or bilateral (both eyes; about one third). In 95 per cent of cases the tumour develops before the age of five. Occasionally babies are born with a retinoblastoma. There is an increased risk of developing other tumours later in life. The commonest signs of retinoblastoma are an abnormal pupil which tends to reflect light as a white reflex - and a squint. The child's vision may also start to deteriorate and the eye may become red and inflamed - and sometimes painful. In the UK, about 40 to 50 children develop this tumour each year. 60 per cent are because of a non-genetic cause but 40 per cent of cases are due to an inherited genetic problem (a faulty gene on chromosome 13 is to blame). As an autosomal recessive condition, both copies of the gene must be damaged for Rb to develop. There are several types of Rb depending on how both gene copies become damaged. Retinoblastoma has one of the highest success rates for treatment for all childhood cancers - nine out of ten children can be cured. Cryotherapy (a freezing treatment), radiotherapy, chemotherapy and surgery are used.
