Cancer Statistics in Korea: Incidence, Mortality, Survival, and Prevalence in 2017

Abstract

PurposeThis study reports the cancer statistics and temporal trends in Korea on a nationwide scale, including incidence, survival, prevalence, and mortality in 2017.Materials and MethodsThe incidence, survival, and prevalence rates of cancer were evaluated using data from the Korea National Cancer Incidence Database from 1999 to 2017 with follow-up until December 31, 2018. Deaths from cancer were assessed using cause-of-death data from 1983 to 2017, obtained from Statistics Korea. Crude and age-standardized rates (ASRs) for incidence, mortality, and prevalence, and 5-year relative survival rates were calculated and trend analysis was performed.ResultsIn 2017, newly diagnosed cancer cases and deaths from cancer numbered 232,255 (ASR, 264.4 per 100,000) and 78,863 (ASR, 76.6 per 100,000), respectively. The overall cancer incidence rates increased annually by 3.5% from 1999 to 2011 and decreased by 2.7% annually thereafter. Cancer mortality rates have been decreasing since 2002, by 2.8% annually. The 5-year relative survival rate for all patients diagnosed with cancer between 2013 and 2017 was 70.4%, which contributed to a prevalence of approximately 1.87 million cases by the end of 2017.ConclusionThe burden of cancer measured by incidence and mortality rates have improved in Korea, with the exception of a few particular cancers that are associated with increasing incidence or mortality rates. However, cancer prevalence is increasing rapidly, with the dramatic improvement in survival during the past several years. Comprehensive cancer control strategies and efforts should continue, based on the changes of cancer statistics.

Trends of Incidence and Survival Rrates of Mucosa-associated Lymphoid Tissue Lymphoma in the Korean Population: Analysis of the Korea Central Cancer Registry Database

“…The crude incidence rate was defined as the total number of newly diagnosed cases in a year divided by the mid-year population in Korea. 18 The age-standardized incidence rate, which is the weighted average of the age-specific rates, was calculated using Segi's world standard population. 18 19 Relative survival is defined as the ratio of the survival rates of people who have a specific disease to the survival rates of those who do not have the disease.…”

The relative survival rate (RSR) was adjusted for the expected mortality of the general population of the same age and sex.…”

Alterations in Gastric Microbial Communities are Associated with Risk of Gastric Cancer in a Korean Population: A Case-Control Study

“…The GC incidence in eastern Asia, including Korea, is the highest worldwide, which is over 4 times higher than the rates in Western Europe [2]. In 2017, according to the Korea Central Cancer Registry (KCCR), the ageadjusted incidence rate of GC was 32.0 per 100,000 in the overall population, 46.4 per 100,000 in men, and 19.6 per 100,000 in women [3]. Various epidemiological studies have demonstrated that smoking [4][5][6][7], alcohol consumption [4,5,8], obesity and physical inactivity [4,5,9], family history of GC [10][11][12][13][14] and numerous dietary factors such as foods preserved with salts, pickled vegetables, low fruits and vegetables consumption, low dietary vitamin C and carotenoid intake, high salt consumption, high processed meat consumption, high salt intake [4,5,15,16] are associated with the increased risk of GC.…”

Association of breast cancer and diabetes mellitus in Korean postmenopausal women

“…Breast cancer is the most common cancer in women [1] [2]. Diabetes mellitus is a serious and growing health problem worldwide, characterized by insulin resistance and hyperinsulinemia [3].…”
