Primary vitreoretinal lymphoma (PVRL) is the most common intraocular lymphoma occurring in the eye. Majority of the patients with PVRL develop central nerve system lymphoma (CNSL) within a few years and thereby a poor prognosis. Although five-year survival rate of PVRL has been reported to be approximately 60%, clinical data of long-term survival is unclear because periodical follow up is difficult once CNSL occurred. In this study, we analyzed the clinical features of patients with PVRL who could followed for long time.
We analyzed the clinical features of 14 patients diagnosed with PVRL who were able to be followed for longer than 5 years from 1994 to 2011 at the Department of Ophthalmology, Tokyo Medical University Hospital. This retrospective study was based on review of medical records.
Of the 14 patients (3 males, 11 females; mean age, 63.8 ± 6.3 years; mean follow-up duration, 90.3±27.9 months), 7 (50%) had unilateral PVRL and 7 (50%) had bilateral PVRL as onset. Thirteen patients (93%) developed CNSL during the follow-up period. The average of overall survival from onset was 7.6 years (range, 5.1-14.1 years). The average of progression free survival from onset was 24.8 months (range, 2-79 months). The average period between onset of PVRL and developing of CNSL was 34.1 months (range, 15-84 months). The average number of relapses during follow-up was 3.7 (range, 0-18); comprising 2.1 (0-16) in eyes and 1.2 (0-3) in CNSL and 0.4 (0-2) in other organs.
Periodical and careful follow-up is critical for patients with PVRL because intra-ocular and CNS relapses are common even in patients who survive long-term.
