Objective: The aim of this report is to provide accurate nationwide epidemiologic data on primary brain and central nervous system (CNS) tumors in Republic of Korea. In 2010, we had reported first nationwide epidemiologic data on primary brain tumors diagnosed in 2005. In this report, we updated the data by analyzing primary brain and CNS tumors diagnosed in 2010 using the data from national cancer incidence database. Methods: Data on primary brain and CNS tumors diagnosed in 2010 were collected from the Korean Central Cancer Registry. Crude and age-standardized rates were calculated in terms of gender, age, and histological type. Results: A total of 10,004 patients diagnosed with primary brain and CNS tumors in 2010 were included in this study. Brain and CNS tumors occurred in females more often than in males (female to male, 1.59 : 1). The most common tumor was meningioma (35.5%). Pituitary tumors (18.7%), gliomas (15.1%), and nerve sheath tumors (10.3%) were followed in incidence. Glioblastoma accounted for 34.6% of all gliomas. In children (<20 years), sellar region tumors (pituitary and craniopharyngioma), embryonal/primitive/medulloblastoma, and germ cell tumors were the most common tumors. Conclusion : Data from this study should provide valuable information regarding the primary brain tumors epidemiology in Republic of Korea.

An Updated Nationwide Epidemiology of Primary Brain Tumors in Republic of Korea, 2013

Background This report aims to provide accurate nationwide epidemiologic data on primary brain and central nervous system (CNS) tumors in the Republic of Korea. We updated the data by analyzing primary brain and CNS tumors diagnosed in 2013 using the data from the national cancer incidence database. Methods Data on primary brain and CNS tumors diagnosed in 2013 were collected from the Korean Central Cancer Registry. Crude and age-standardized rates were calculated in terms of gender, age, and histological type. Results A total of 11,827 patients were diagnosed with primary brain and CNS tumors in 2013. Brain and CNS tumors occurred in females more often than in males (female:male, 1.70:1). The most common tumor was meningioma (37.3%). Pituitary tumors (18.0%), gliomas (12.7%), and nerve sheath tumors (12.3%) followed in incidence. Glioblastomas accounted for 41.8% of all gliomas. In children (<19 years), sellar region tumors (pituitary and craniopharyngioma), embryonal/primitive/medulloblastoma, and germ cell tumors were the most common tumors. Conclusion This study should provide valuable information regarding the primary brain tumor epidemiology in Republic of Korea

Incidence of Primary Spinal Cord, Spinal Meninges, and Cauda Equina Tumors in Korea, 2006-2010
Jung, Kyu-Won,Park, Kwang Hyon,Ha, Johyun,Lee, Seung Hoon,Won, Young-Joo,Yoo, Heon Korean Cancer Association 2015 Cancer Research and Treatment Vol.47 No.2
<P><B>Purpose</B></P><P>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.</P><P><B>Materials and Methods</B></P><P>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.</P><P><B>Results</B></P><P>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.</P><P><B>Conclusion</B></P><P>This study provides the first population-based analysis of PSCATs in Korea.</P>

Objective To investigate the incidence, trends, and survival rates of all gynecologic cancers using the Korea Central Cancer Registry (KCCR) database from 1999-2019. Methods Gynecologic cancer data were obtained from the KCCR database between 1999 and 2019. Age-standardized incidence rates (ASRs), annual percentage changes, and average annual percentage changes (AAPCs) were calculated. The relative survival rate (RSR) was reported by age group, stage, and 6-year period (I: 1999-2005, II: 2006-2012, III: 2013- 2019). Results The gynecologic cancer ASRs were 26.2 and 24.9 per 100,000 individuals in 1999 and 2019, respectively. Trends of incidence in gynecologic cancer revealed a decrease in cervical cancer and gestational trophoblastic neoplasia (GTN) with AAPCs of -3.4 and -4.3, respectively. Conversely, the incidence of uterine, ovarian, and vulvar cancers increased with AAPCs of 4.7, 2.3, and 2.1, respectively. AAPC for vaginal cancer showed no change. The 5-year survival rate was highest for GTN (90.5%) and lowest for vaginal cancer (56.6%). An increase in age was correlated with poorer survival rates across all gynecologic cancers, excluding vaginal cancer. For all gynecologic cancer types, the prognosis deteriorates with advancing cancer stages. The RSR of uterine cancer improved consistently across all periods. The ovarian cancer RSR improved more in period III than in periods I or II. Additionally, the vulvar cancer RSR improved more in periods II and III than in period I. Conclusion In Korea, the incidence of cervical cancer and GTN decreased, whereas the incidence of uterine, ovarian, and vulvar cancer increased from 1999 to 2019. The RSR for uterine, ovarian, and vulvar cancers showed consistent improvements over different periods. Effective screening programs and the adoption of advanced treatments may be necessary to further reduce the burden of gynecologic cancer.
