Retinoblastoma, a rare form of ocular cancer, is primarily diagnosed in early childhood. It is characterized by the rapid development of tumors in the retina, the light-sensitive tissue at the back of the eye. With advancements in genetic testing, the diagnosis and management of retinoblastoma have significantly improved.
The prevalence of retinoblastoma is estimated to be 1 in every 15,000 to 20,000 live births worldwide. It accounts for approximately 3% of all pediatric cancers. Inherited cases, known as hereditary retinoblastoma, comprise about 40% of all retinoblastoma cases, while non-inherited, or sporadic retinoblastoma, accounts for the remaining cases.
Retinoblastoma follows an autosomal dominant inheritance pattern, meaning that a child has a 50% chance of inheriting the mutated gene from an affected parent. The causative genes involved in retinoblastoma are the RB1 gene, which is mutated in hereditary cases, and other genes like MYCN, MDMX, and others, which are involved in non-inherited cases.
The prognosis of retinoblastoma depends on various factors, including the stage of the cancer at the time of diagnosis and the presence of metastasis. Early detection and appropriate treatment can significantly improve the prognosis. The main treatment options for retinoblastoma include chemotherapy, radiation therapy, and enucleation (surgical removal of the affected eye).
Several risk factors have been associated with retinoblastoma, including a family history of the disease, young maternal age, and exposure to ionizing radiation. However, it is important to note that most cases of retinoblastoma occur sporadically without any known risk factors.
In conclusion, genetic testing plays a crucial role in the diagnosis and management of retinoblastoma. It helps identify individuals at risk of developing the disease, facilitates early detection, and enables personalized treatment options. Further research into the underlying genes and mechanisms involved in retinoblastoma will continue to improve our understanding and provide new insights into targeted therapies.
Overview of Genereviews Retinoblastoma
Retinoblastoma is a rare form of eye cancer that primarily affects children. It is characterized by the development of tumors in the retina, the light-sensitive tissue at the back of the eye. These tumors can lead to visual impairment and, if left untreated, can be life-threatening.
The majority of retinoblastoma cases are caused by mutations in the RB1 gene, which is responsible for regulating cell growth and division in the retina. In some cases, the condition can be inherited from a parent who carries a mutated copy of the gene.
Genetic testing is often used to diagnose retinoblastoma and determine its underlying cause. This may involve analyzing a blood sample to look for mutations in the RB1 gene. Additionally, imaging tests, such as ultrasound or MRI, may be performed to assess the extent of the tumors.
Treatment options for retinoblastoma depend on the size and location of the tumors, as well as the overall health of the child. In some cases, small tumors can be treated with laser therapy or cryotherapy, which use targeted methods to destroy the cancerous cells.

While the disease can be challenging, advancements in medical care offer hope for a positive prognosis and long-term survival.
Risk Factors
Inherited retinoblastoma is caused by genetic mutations in the RB1 gene, which is responsible for regulating cell growth and division in the retina. In most cases, individuals with a family history of retinoblastoma inherit the mutated RB1 gene from one of their parents. However, about 15% of cases are caused by new mutations in the RB1 gene and are not inherited.
Individuals with the familial form of retinoblastoma have a higher risk of developing bilateral tumors (affecting both eyes) compared to those with the sporadic form of the disease. Furthermore, individuals with the hereditary form of retinoblastoma have an increased risk of developing additional tumors later in life, including other types of cancer.
Retinoblastoma can also occur sporadically, without a family history of the disease. In these cases, the genetic mutations in the RB1 gene occur randomly, and there is no increased risk of developing additional tumors. Sporadic retinoblastoma usually affects only one eye.
The specific genetic mutations in the RB1 gene can affect the severity and prognosis of retinoblastoma. Certain mutations are associated with a higher risk of tumor formation and a worse prognosis, while other mutations may result in milder disease and a better outcome.
While retinoblastoma can occur in individuals of any age, it is most commonly diagnosed in early childhood. The average age of diagnosis is around 12 to 18 months. However, retinoblastoma can be detected prenatally through genetic testing or shortly after birth during a routine eye examination.
There are no known environmental or lifestyle factors that directly cause retinoblastoma. However, certain risk factors can increase the likelihood of developing the disease. These include having a family history of retinoblastoma, certain genetic syndromes (such as Li-Fraumeni syndrome), exposure to radiation, and being born prematurely.
Early detection and diagnosis of retinoblastoma are crucial for successful treatment and preserving vision. Genetic testing can help identify individuals at risk of developing retinoblastoma and guide appropriate screening and management strategies.
The prevalence of retinoblastoma is relatively rare, with an estimated incidence of 1 in every 15,000 to 20,000 live births. However, the prevalence may vary depending on the population and geographic location.

Types and Stages
Retinoblastoma is a rare type of eye cancer that primarily affects young children. It can occur in one or both eyes and is typically diagnosed before the age of 5. There are two main types of retinoblastoma: sporadic and hereditary.
In sporadic retinoblastoma, the cancer develops randomly and is not caused by an inherited genetic mutation. This type constitutes the majority of cases and typically has a better prognosis. Symptoms may include white pupils (instead of the normal red-eye reflection) in photographs, crossed eyes or strabismus, poor vision, and eyes that appear to be looking in different directions.
Hereditary retinoblastoma, on the other hand, is caused by an inherited genetic mutation in the RB1 gene, which is responsible for controlling cell growth in the retina. This type tends to affect both eyes and increases the risk of developing other types of cancer later in life. Genetic testing can be used to determine if a person has the RB1 mutation and is at risk for developing retinoblastoma.
The stages of retinoblastoma are classified based on the extent of the cancer’s spread. In intraocular retinoblastoma, the tumor is confined to the eye, while extraocular retinoblastoma has spread beyond the eye. Intraocular retinoblastoma can further be classified as either unilateral or bilateral, depending on whether one or both eyes are affected.
Early diagnosis and treatment are crucial for improving the prognosis of retinoblastoma. If detected early, the chances of preserving vision and preventing the spread of the cancer are higher. Regular eye exams, especially for children with a family history of retinoblastoma, can help with early detection.
