Overview
The incidence of retinoblastoma in United States is approximately 4.3 cases per 1000,000 children under 15 years of age.[1] The median age at diagnosis of retinoblastoma is 18 months. An average age at diagnosis of retinoblastoma for children with bilateral disease is 12 months and for children with unilateral disease average age at diagnosis is 24 months.[2] Retinoblastoma affects males and females equally.[3] There is no racial predilection to the development of retinoblastoma.[3]
Epidemiology and Demographics
Incidence
The incidence of retinoblastoma in United States is approximately 4.3 cases per 1000,000 children under 15 years of age.[1] The age-adjusted annual incidence in children aged 0 to 4 years is 10 to 14 cases per 1 million (approximately one in 14,000–18,000 live births).[4] In the US, there are 250 to 350 new cases of retinoblastoma per year. Retinoblastoma presents with cumulative lifetime incidence rate of 1 case of retinoblastoma per 18000 to 30000 live births worldwide.[5] 90% of the retinoblastoma cases are diagnosed before three years of age.
Age
The median age at diagnosis of retinoblastoma is 18 months. An average age at diagnosis of retinoblastoma for children with bilateral disease is 12 months and for children with unilateral disease an average age at diagnosis is 24 months.[2] Approximately 95% of children with retinoblastoma present before the age of 5 years.[3]. However, cases of newly diagnosed retinoblastoma have been reported in children as old as 18 years[6][7][8][9] and even in adults.[10][11][12]
Gender
Retinoblastoma affects males and females equally.[3]
Race
There is no racial predilection to the development of retinoblastoma.[3]
