We obtained data from the Information Technology Statistics of Korea (1984-2017) and Korea Central Cancer Registry (1999-2017). The average annual percent change was estimated using Joinpoint regression analysis.

Conditional Relative Survival of Ovarian Cancer: A Korean National Cancer Registry Study.

Objective: Conditional relative survival (CRS) rates, which take into account changes in prognosis over time, are useful estimates for survivors and their clinicians as they make medical and personal decisions. We aimed to present the 5-year relative conditional survival probabilities of patients diagnosed with ovarian cancer from 1997-2016.

Methods: This nationwide retrospective cohort study used data from the Korean Central Cancer Registry.

Conditional relative survival of cervical cancer: a Korean National Cancer Registry Study.

Objective: Conditional relative survival (CRS) considers changes in prognosis over time and may offer more useful estimates for survivors. We aimed to investigate CRS among patients with cervical cancer stratified by various factors that influence survival probability.

Methods: This nationwide retrospective study used data from the Korean Central Cancer Registry.

A Nationwide, Population-Based Epidemiology Study of Primary Central Nervous System Tumors in Korea, 2007-2016: A Comparison with United States Data.

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.

Different Patterns of Conditional Survival of Breast Cancer Patients by Age and Histologic Types: Evidence from the Korean Nationwide Registry.

Background: Conditional relative survival (CRS), which is the survival estimate of patients who have already survived for a certain period of time after diagnosis, could provide more relevant information on the current prognosis of cancer survivors than the standard 5-year relative survival (RS). This study aimed to estimate the 5-year CRS of Korean breast cancer patients.

Methods: We identified 145,083 breast cancer cases diagnosed between 2002 and 2013 in the Korea Central Cancer Registry.

A Nationwide, Population-Based Epidemiologic Study of Childhood Brain Tumors in Korea, 2005-2014: A Comparison with United States Data.

Background: We investigated the epidemiologic characteristics of childhood brain tumors (CBT) in Korea, and compared our findings with those from the United States.

Methods: We searched the Korea National Cancer Incidence Database of the Korea Central Cancer Registry (KCCR) from 2005 to 2014, which included all Korean patients with CBT aged 0 to 19 years at diagnosis. The age-standardized incidence rates (ASR) and the 5-year relative survival rate (RSR) were determined.

Conditional relative survival of oral cavity cancer: Based on Korean Central Cancer Registry.

Objectives: Conditional relative survival (CRS) describes the survival chance of patients who have already survived for a certain period of time after diagnosis and treatment of cancer. Thus, CRS can complement the conventional 5-year relative survival, which does not consider the time patients have survived after their diagnosis. This study aimed to assess the 5-year CRS among Korean patients with oral cancer and the related risk factors.

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.

Nationwide Population-Based Incidence and Survival Rates of Malignant Central Nervous System Germ Cell Tumors in Korea, 2005-2012.

Purpose: Malignant central nervous system (CNS) germ cell tumors (GCTs), although rare, are thought to occur more frequently among Asians. However, a recent population-based study revealed no differences in GCT incidence between Asians and Caucasians. Therefore, this study was conducted to determine the incidence and survival rates of CNS GCTs using the national cancer incidence database, and to compare these rates to those in the United States and Japan.

Population-based Incidence and Survival for Primary Central Nervous System Lymphoma in Korea, 1999-2009.

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.

Incidence of primary spinal cord, spinal meninges, and cauda equina tumors in Korea, 2006-2010.

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.
