[Radiotherapy of retinoblastoma--analysis of 100 patients].

The prognosis of retinoblastoma, a common endo-ocular malignant tumor in infants, is related to the clinical stage, the size of tumor, involvement of optic nerve and the method of treatment. 100 patients treated were followed for 5-23 years. The 5- and 10- year survival rates were 15% and 7% in patients treated by surgery alone and 58% and 52% by operation combined with radiotherapy. Radiotherapy plays a very important role in the treatment of retinoblastoma.
