title: Treatment of bilateral retinoblastoma stage V at the Curie Foundation. 33 cases.
abstract: A retrospective study was undertaken on 33 patients with bilateral retinoblastoma in whom one eye at least was classified as stage IV or V (Reese-Ellsworth classification). In most cases the other eye had been enucleated elsewhere. Conservative therapy consisted of primary chemotherapy (vincristine, actinomycin, cyclophosphamide) followed by external beam irradiation, six courses of chemotherapy and, if necessary, by cobalt-60 plaques, xenon arc photocoagulation or secondary enucleation. Ten patients were lost to follow-up, eight patients died or are currently being treated for recurrence, 15 patients are alive and free from disease and 42% of eyes at stage IV or V were saved. These results indicate that primary chemotherapy does not improve the final outcome of stage IV or V retinoblastoma, as compared with primary irradiation.
