Primary central nervous system lymphoma (PCNSL) is rare, but its incidence is rapidly increasing. PCNSL is initially radiosensitive, but unfortunately its remission is short-lived, resulted in poor overall survival. The purpose of this study was to investigate the predictor of prognosis in PCNSL.
From January 1983 to December 2006, 63 patients with PCNSL treated by radiation therapy were included. 36 males and 27 females, age ranged from 10 to 89 years old with a median age of 66 years. Performance status (PS) of patients were as follows; PS0 in 6, PS1 in 15, PS2 in 12, PS3 in 12, and PS4 in18. Histopasological diagnosis were obtained in 34 patients. Others were judged from clinical findings.We retrospectively investigated the relationship of patient prognosis to the following clinical variables: patient age, gender, performance status (PS), total radiation dose, initial response. The survival data were analyzed using the Kaplan-Meyer methods and compared using the log-rank test.
For all 63 patients, the median survival time was 14 months and the survival rates were 38% at 2 years and 19% at 5 years. There were no significant predictor, however, patients with younger age (< 60 years) and better PS (PS = 0 or 1) showed better prognosis.
We investigated the prognosis of PCNSL in our institute. Younger age and good PS seemed to be predictors of prognosis in PCNSL.
