Abstract


Purpose: The purpose of this study was to determine the epidemiologic characteristics and survival of patients with primary brain and other central nervous system (CNS) tumors in Korea and to compare our findings with those from the United States.

Materials and Methods: We collected data on primary brain and CNS tumors diagnosed between 2007 and 2016 from the Korea Central Cancer Registry. The age-standardized incidence rates (ASRs) and 5-year relative survival rates (RSRs) were evaluated. We applied the classification and definitions of the Central Brain Tumor Registry of the United States to our analysis for direct comparison with United States data.

Results: A total of 115,050 primary brain and CNS tumors were identified, and the ASR of all tumors was 22.01 per 100,000 individuals, which was lower than the 23.41 in the United States. However, the ASR of malignant tumors was significantly lower herein (4.27) than in the United States (7.08). Meningeal tumors were the most common histologic group among all tumors (ASR, 8.32). The 5-year RSR of all primary brain and other CNS tumors was 86.4%, and that of all malignant tumors was 44.1%, which was higher than the 35.8% observed in the United States. Among malignant tumors, glioblastomas had the lowest 5-year RSR (12.1%).

Conclusion: In Korea, malignant brain and other CNS tumors have a lower incidence and better survival outcome.
