Cancer Statistics in Korea: Incidence, Mortality, Survival, and Prevalence in 2015

Abstract

PurposeThis study presents the 2015 nationwide cancer statistics in Korea, including the incidence, survival, prevalence, and mortality.Materials and MethodsCancer incidence data from 1999 to 2015 was obtained from the Korea National Cancer Incidence Database and followed until December 31, 2016. Mortality data from 1983 to 2015 were obtained from Statistics Korea. The prevalence was defined as the number of cancer patients alive on January 1, 2016, among all cancer patients diagnosed since 1999. Crude and age-standardized rates (ASRs) for incidence, mortality and prevalence and 5-year relative survivals were also calculated.ResultsHerein, 214,701 and 76,855 Koreans were newly diagnosed and died from cancer in 2015, respectively. The ASRs for cancer incidence and mortality in 2015 were 258.9 and 82.0 per 100,000, respectively. The overall cancer incidence rate has increased significantly by 3.4% annually from 1999 to 2012, and started to decrease after 2012 (2012-2015, annual percent change, –6.1%). However, the overall cancer mortality has decreased 2.7% annually since 2002. The 5-year relative survival rate for patients diagnosed with cancer between 2011 and 2015 was 70.7%, an improvement from the 41.2% for patients diagnosed between 1993 and 1995.ConclusionAge-standardized cancer incidence rates have decreased since 2012 and mortality rates have declined since 2002; however, the 5-year survival rates have improved remarkably from 1993-1995 to 2011-2015 in Korea.

Neutrophil‐to‐lymphocyte ratio and risk of lung cancer mortality in a low‐risk population: A cohort study

“…However, further studies are needed to evaluate the relationship of NLR and PLR with lung cancer incidence using lung cancer incidence data, histological subtypes and other risk factors in addition to smoking. Furthermore, with the introduction of targeted therapy for EGFR mutation positive lung cancer, there have been improvements in survival in patients with lung cancer over the recent decades in Korea . Therefore, in our study, there is a possibility that lung cancer mortality more likely reflected lung cancers with poor prognosis than lung cancer with an indolent nature .…”

“…Lung cancer imposes a substantial burden of disease and remains the most common cause of cancer‐related death worldwide, representing 19% of all cancer‐related deaths . According to the annual report of cancer statistics from the Korea Central Cancer Registry, lung cancer was the leading cause of cancer‐related death in Korea in 2015, in both men and women . Lung cancer screening with low‐dose computed tomography targeting high‐risk ever‐smokers has been widely adopted in the United States based on a 20% reduction in mortality from lung cancer among high‐risk individuals using National Lung Screening Trial inclusion criteria, which comprise age and smoking history .…”

The prevalence of histologic atrophy and intestinal metaplasia in the corpus has decreased over 15 years in females in the Korean population

“…In addition, GC is the third leading cause of cancer deaths in both sexes worldwide (723 000 deaths) . In Korea, GC has the most frequent incidence (57.3/100 000), and it is the third leading cause of cancer‐related deaths (16.7/100 000) . In a recent study, the incidence of GC is generally in direct proportion to the prevalence of H pylori infection.…”

“…A recent meta‐analysis of 169 studies of adults reported that the male sex was associated with a higher prevalence of H pylori (OR, 1.12; 95% CI: 1.09‐1.15) . The incidence rate of GC in Korean males, 76.8 per 100 000, is nearly two times greater than that in Korean females (37.9 per 100 000) . In 2016, according to statistics from the Korea Centers for Disease Control and Prevention, the smoking rate was 40.7% in males and 6.4% in females (http://www.index.go.kr/unify/idx-info.do?idxCd=http://4038).…”

Prevalence of human papillomavirus-related diseases in the Republic of Korea: a cross-sectional study

“…In 2007, HPV accounted for 10.4%–11.3% of infection-related cancers and 6% of deaths in Korea 5. Cervical cancer incidence and mortality in Korea are decreasing steadily (age-standardised rate (ASR) for incidence: from 16.3 per 100 000 women in 1999 to 9.1 in 2015; ASR for mortality: from 2.6 per 100 000 women in 1999 to 2.0 in 2015),6 partly due to organised cervical cancer screenings 7. Currently, the Korean government operates two population-based cervical screening programmes: the National Health Insurance Service Cancer Screening Programme (NHISCSP) for National Health Insurance Service (NHIS) beneficiaries in the upper 50% income stratum, and the National Cancer Screening Programme (NCSP) for NHIS beneficiaries in the lower 50% income stratum and Medical Aid recipients.…”
