- Abstract: PURPOSE: Primary spinal cord and appendage tumors (PSCAT) originating from the spinal cord, spinal meninges, and cauda equina are uncommon. Worldwide, population-based cancer registry data are mostly based on malignant tumors only, which means few data are available on PSCATs, including non-malignant tumors. Therefore, the objective of this study was to provide information regarding the incidence of both non-malignant and malignant PSCATs in Korea on a national level. MATERIALS AND METHODS: Incidence of PSCATs was estimated from cases diagnosed between 2006 and 2010 using the National Cancer Incidence Database in Korea. Age-adjusted rates were calculated using the world standard population, and male-to-female rate ratios were calculated by histology type. RESULTS: Of all PSCATs registered (n=3,312), 86.6% were non-malignant. The overall age-adjusted incidence of PSCATs was 1.08 per 100,000 person-years, with an incidence of 0.99 per 100,000 in females and 1.15 in males. The most common site of PSCATs was the spinal cord (83.4%), followed by spinal meninges (16.1%) and cauda equina (0.5%). The most common histological type was neurilemmoma (41.3%), followed by meningiomas (20.1%) and ependymomas (7.6%). Men had significantly higher rates than women for ependymomas and lymphomas but had lower rates for meningiomas. CONCLUSION: This study provides the first population-based analysis of PSCATs in Korea.
