Radiotherapy in multimodality treatment of retinoblastoma in children

The results of multimodality therapy of 50 children with uni- or bilateral retinoblastoma were assessed with the application of a special protective collimator and polychemotherapy as modalities supplementing eye extirpation. Some patients were irradiated prior to operation, the others following it. Patients with Stage 1 retinoblastoma were subjected to chemo- and radiotherapy; 16 out 18 patients have been alive for 2 yrs. It has been stressed that radiation therapy is an important component in multimodality therapy. It can be used as a modality of the combined method of tumor surgical removal or as a method of radical therapy in early forms of the disease
