Overview
Common risk factors in the development of retinoblastoma are advanced paternal age, positive family history, and viral exposure.[1][2][3]
Risk Factors
Family history
- Approximately 10% of patients with retinoblastoma have a previously established family history of the disease.[1] In patients with bilateral retinoblastoma, unilateral retinoblastoma with a family history, or unilateral retinoblastoma with a proven RB1 somatic mutation there is 50 percent risk of passing the mutation on to their offspring. The risk of retinoblastoma may also be increased among siblings of a patient with retinoblastoma as one parent may have somatic mosaicism for the RB1 deletion or may be a silent carrier of RB1 mutation.[4]
- The magnitude of risk among relatives of the proband depends upon the tumor presentation in the proband (ie, unilateral or bilateral; unifocal or multifocal).
- The below table is the calculated risk of relatives to carry the mutated gene.[5]
Relative of patient | Bilateral involvement (100%) | Unilateral involvement (15%) |
---|---|---|
Offspring (infant) | 50 | 7.5 |
Parent | 5 | 0.8 |
Sibling | 2.5 | 0.4 |
Niece/nephew | 1.3 | 0.2 |
Aunt/uncle | 0.1 | 0.007 |
First cousin | 0.05 | 0.007 |
HPV virus exposure
- The presence of HPV sequences in retinoblastoma tumor tissue may play a role in the development of sporadic retinoblastoma.[2]
- There is evidence suggesting that the mutations of RB1 are more common during spermatogenesis than oogenesis.[3]
Environmental factors
- Epidemiologic data indicated that retinoblastoma has higher incidence in some geographic areas.
- The table below provides regions with highest incidence rate of retinoblastoma.
Country | Incidence |
---|---|
Mali | 4.25 |
Uganda | 2.4 |
Zimbabwe | 2.33 |
Hawaii | 2.25 |
India | 1.96 |
Vietnam | 1.89 |
Singapore | 1.88 |
New Zealand | (1.78-1.86) |
