[Radiotherapy of malignant lymphoma of the orbit]

Gamma-beam therapy of malignant orbital lymphomas of 1 year to 7 years 5 months duration ensured the cure of a primary orbital focus in all 8 patients. The total focal dose of 30 Gy (10 irradiation sessions) was sufficient for control. Generalization was noted in 3 (42.8%) patients, one patient died from intercurrent disease in 7 months. Taking into account some features of metastasizing and avoiding the first barrier of the lymph nodes their elective irradiation was not recommended.
