PURPOSE: To determine the significance of both massive choroidal invasion and optic nerve invasion (retrolaminar [(RL]+cut end [CE]) as a criterion for classifying high metastatic potential retinoblastoma and their relationship with other known histopathological high-risk features.
METHODS: A retrospective review of 650 eyes diagnosed as retinoblastoma over a 10-year period. In our study, there is male predominance and a higher percentage of the poorly differentiated tumors. The age of most of the patients ranges from 1 month to 8 years with a median age of 2 years.
RESULTS: There were 24% of eyes with massive choroidal invasion and 18% of eyes with optic nerve invasion up to the cut end. On performing Cox-proportional hazard analysis, it was found that massive choroidal invasion in association with optic nerve invasion up to the cut end was an independent prognostic parameter. On Kaplan-Meier analysis, overall survival had reduced in patients having both massive choroidal invasion and an optic nerve cut end invasion along with orbital invasion (P < .05).
CONCLUSION: The presence of massive choroidal invasion in association with optic nerve cut end invasion (RL+CE) could be used as a better prognostic predictor in assessing retinoblastoma patients with high metastatic potential and need to be kept for longer follow up.
