Overview
Retinoblastoma may be classified into several subtypes based on the International Retinoblastoma Staging System (IRSS).
Staging
A number of systems have been devised to stage retinoblastoma, with various end-points, and multiple systems are often used concurrently. The Reese Ellsworth classification is assessed with fundoscopy and aims at predicting the chance of preserving the eye with external beam radiotherapy. . More relevant to radiology practice is the International retinoblastoma classification which predicts overall survival
The International Retinoblastoma Staging System (IRSS)
| Stage | Features |
|---|---|
| Stage 0 | Patients treated conservatively |
| Stage I | eye enucleated, completely resected histologically |
| Stage II | eye enucleated, microscopic residual tumor |
| Stage III | regional extension |
| Stage III A | overt orbital disease |
| Stage III B | preauricular or cervical lymph node extension |
| Stage IV | Metastatic disease |
| Stage IV A |
