Retinoblastoma, the most common childhood eye cancer, arises from RB1 gene mutations. Early diagnosis and specialized care significantly improve survival rates, exceeding 95% for localized disease.
Area of Science:
- Pediatric Oncology
- Ophthalmology
- Genetics
Background:
- Retinoblastoma is the most frequent intraocular malignancy in children.
- It originates from biallelic RB1 tumor suppressor gene mutations, causing retinal cell transformation.
- Common presentations include leukocoria (white pupil) and strabismus.
Purpose of the Study:
- To provide a comprehensive overview of retinoblastoma.
- To cover epidemiology, genetics, screening, diagnosis, classification, and current treatments.
- To highlight the importance of staging and multidisciplinary care.
Main Methods:
- Review of epidemiological data.
- Analysis of genetic underpinnings (RB1 gene).
- Summary of diagnostic and staging criteria (AJCC TNMH system).
- Overview of current therapeutic modalities.
Main Results:
- Heritable retinoblastoma constitutes 45% of cases, with 80% being bilateral.
- Prognosis is strongly linked to disease stage at presentation.
- Survival rates exceed 95% with early diagnosis and specialized treatment.
- Survival drops below 50% with extraocular spread.
Conclusions:
- Retinoblastoma management requires a multidisciplinary approach.
- The AJCC TNMH staging system is crucial for prognosis.
- Timely diagnosis and treatment in specialized centers are vital for optimal outcomes.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
