[Multimodality treatment for retinoblastoma in children].
A comprehensive programme was developed for the treatment of uni- and bilateral retinoblastoma in children with due regard to the disease stage by the TNM system. The use of the current sources of teletherapy and cyclic polychemotherapy expanded indications for organ-saving therapy at most common stages. Treatment by the program was performed in 202 patients, including 125 children with unilateral damage and 77 with bilateral damage. An attempt made treat 140 (75%) children at the first stage. More than 70% of cases were diagnosed as having disease stage T3 in one or two stage, while such patients underwent ocular enucleation. A complete or partial (more than 50%) tumor regression without signs of its progression for 2 years or more was achieved in 62% of cases. At the first stage of therapy, conservative therapy insignificantly affected the children's longevity in uncomplicated cases, which is particularly important in bilateral involvement, while this preserved the organ of vision in more than half the patients (62%). Five-year survival was 92 and 82% in unilateral retinoblastoma surgically treated and untreated, 83 and 84%, respectively. Adequate multimodality treatment brought about low incidence rates of recurrence and metastasis (10%) in conservative therapy and 7.7% among all patients.
