The role of radiation therapy in the management of ocular reticulum cell sarcoma

Abstract

Nine patients with ocular lymphomas were seen in the Department of Ophthalmology and the Division of Radiation Oncology at UCSF and Ralph K. Davies Medical Center, San Francisco, from 1978 through 1974. Six of the 9 patients had visual symptoms as the first manifestation of their disease. Eight of the 9 patients developed intracranial lymphoma at some time during the course of the disease. Despite lymphoma work-up including bone marrow biopsies and lymphangiogram, only 1 patient was found to have documented systemic involvement. The diagnosis of ocular lymphoma was based on pathologic material from the eye in 5 cases or from central nervous system biopsy in 4 patients in association with tumor cell infiltrates in the retina and vitreous clouding. Radiation therapy to the eyes improved vision in 10 of 13 eyes treated in 8 patients. The usual dose was in the range of 3500 to 4500 rads given over 4-5 weeks. In addition, 7 patients received central nervous system irradiation. Review of the literature reinforced the findings of this series showing the frequent association of ocular lymphoma with intracranial lymphoma and the rare systemic dissemination. This disease process has previously been referred to as ocular reticulum cell sarcoma.
