- Abstract
Purpose Primary central nervous system lymphoma (PCNSL) is an uncommon brain tumor accounting for 2%-5% of all primary brain tumors. Few population-based analyses of survival for patients with PCNSL have been conducted, particularly in Asian countries. Materials and Methods Using the Korea National Cancer Incidence Database, 1,062 cases of PCNSL newly diagnosed from 1999 to 2009 were analyzed. The crude rate, age-standardized rate (ASR), and annual percent change were calculated. To estimate the observed survival, we restricted the data to between 1999 and 2007 and followed the cases until December 2010. The overall survival was estimated using the Kaplan-Meier method, and piecewise Poisson regression model. Results The ASR for PCNSL between 1999 and 2009 was 0.17 per 100,000, and the annual percent change from 1999 to 2009 was 8.8% (p < 0.001). The ASR of males was higher than that of females, and the older groups (60s or over) showed the largest increase in incidence rates. For all ages, the five-year survival from PCNSL was 29.9% between 1999 and 2007. Survival from PCNSL is known to show strong association with age at diagnosis. Conclusion These results are similar to those of previous studies. Our findings may be helpful to clinicians and patients in determining long-term prognoses for PCNSL.
