Clinical audit of retinoblastoma management: a retrospective single-institution study.

Objective: The primary aim of this study was to identify the frequency of death, metastasis, enucleation, and use of external beam radiation therapy (EBRT) among retinoblastoma patients. The secondary aim was to determine whether any events were associated with suboptimal clinical management to identify areas for clinical care improvement.

Methods: Patients diagnosed with retinoblastoma between January 1, 2000, and December 31, 2015, at The Hospital for Sick Children were included.
