Incidence of Primary Spinal Cord, Spinal Meninges, and Cauda Equina Tumors in Korea, 2006-2010

Abstract

PurposePrimary 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 MethodsIncidence 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.ResultsOf 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.ConclusionThis study provides the first population-based analysis of PSCATs in Korea.

A Nation-Wide Epidemiological Study of Newly Diagnosed Primary Spine Tumor in the Adult Korean Population, 2009-2011

“…On the other hand, incidence of primary malignant spine tumor was lower in women than that in men (Table 2). This tendency was similar to previous a recent Korean study7) and previous studies of the United States3,15).…”

“…The second most common tumor type was a neoplasm of the vertebral column among the primary malignant tumors and neoplasm of the spinal meninges among the primary nonmalignant spine tumors. This tendency is in good agreement with a histology based nationwide Korean study7). As we described in our previous study, this tendency is in line with previous studies which found that spinal cord tumors were the most common, followed by spinal meninges tumors 3,15).…”

“…Several population-based incidence rates of spine tumor have been reported4,7,10,13,15,17). Among these population-based studies, there have been 2 nation-wide studies in Korea7,17).…”

“…Among these population-based studies, there have been 2 nation-wide studies in Korea7,17). Such efforts could provide information to health care agencies and stimulate research on primary spine tumors.…”

Schwannoma de cauda equina com acometimento vertebral: relato de caso e revisão de literatura

“…3 extramedulares ou intradurais intramedulares. O schwannoma é um tumor de bainha nervosa, sendo, portanto, intradural extramedular, embora alguns possam crescer a ponto de terem componente extradural ou mesmo serem completamente extradurais, 1,4 havendo inclusive relato de casos em que o schwannoma não se liga ao tecido nervoso.…”
