Cancer Statistics in Korea: Incidence, Mortality, Survival, and Prevalence in 2013

Abstract

Purpose This study described the 2013 nationwide cancer statistics in Korea, including cancer incidence, survival, prevalence, and mortality. Materials and Methods Cancer incidence data from 1999-2013 were obtained from Korea National Cancer Incidence Database and followed until December 31, 2014. Mortality data from 1983-2013 were obtained from Statistics Korea. The prevalence was defined as the number of cancer patients alive on January 1, 2014 among all cancer patients diagnosed since 1999. Crude, and age-standardized and 5-year relative survival rates were also calculated. Results In 2013, a total of 225,343 and 75,334 Koreans were newly diagnosed and died from cancer, respectively. The age-standardized rates for cancer incidence and mortality in 2013 were 290.5 and 87.9 per 100,000, respectively. The age-standardized cancer incidence rate increased 3.1% annually between 1999 and 2013. However, the overall cancer incidence rates have decreased slightly in recent years (2011 to 2013). The age-standardized rate for all-cancer mortality has decreased 2.7% annually since 2002. Overall, the 5-year relative survival rate for people diagnosed with cancer between 2009 and 2013 was 69.4%, which represents an improved survival rate as compared with 41.2% for people diagnosed between 1993 and 1995. Conclusion Age-standardized cancer incidence rates have decreased between 2011 and 2013; mortality rates have also declined since 2002, while 5-year survival rates have improved remarkably from 1993-1995 to 2009-2013 in Korea.
