RESULTS OF COMBINED CHEMOTHERAPY AND RADIOTHERAPY FOR ADVANCED INTRAOCULAR RETINOBLASTOMA

Objective: To determine the visual and anatomical results and survival after combined chemotherapy and whole eye radiotherapy for patients w ith bilateral Reese-Ellsworth group V retinoblastoma. Setting: A natio nal referral center for retinoblastoma. Patients: Fourteen patients wi th bilateral Reese-Ellsworth group V retinoblastoma seen between March 1, 1989, and April 30, 1995, were treated. Interventions: Patients we re treated with chemotherapy (using carboplatin, etoposide, and vincri stine) and whole eye radiotherapy (40-44 Gy in 20-22 equivalent fracti ons). A medical record review was performed to determine outcomes. Mai n Outcome Measures: Survival, eye preservation rate, and visual acuity . Results: Two patients died, 1 from a primitive neuroectodermal tumor and the other from the meningeal spread of retinoblastoma. Four eyes were enucleated primarily because of severe disease at presentation. O f the remaining 20 eyes, 6 required enucleation. The disease recurred in 4 of those patients, and neovascular glaucoma developed in 2 patien ts. Of the 12 surviving children, 5 have a visual acuity better than 1 /60 in at least 1 eye. Conclusion: Although most of the treated group V eyes could be salvaged with chemotherapy plus radiotherapy, the resu ltant visual acuity was often poor.
