Extraocular retinoblastoma: A 13‐year experience

In the current study, the addition of ifosfamide and etoposide to a treatment regimen comprised of cisplatin, teniposide, vincristine, doxorubicin, and cyclophosphamide did not appear to improve the survival of patients with extraocular retinoblastoma. Patients with dissemination to the central nervous system or metastatic disease remain incurable and die of progressive disease, despite the aggressive treatment. A multicenter trial should be considered to evaluate the best strategy for these situations.
