Changing trends in the incidence (1999-2011) and mortality (1983-2013) of cervical cancer in the Republic of Korea.
Bottom Line: Yearly age-standardized rates (ASR) per 100,000 were compared using two standards: the 2005 Korean population and the world standard population, based on Segi's world standard for incidence and the World Health Organization for mortality.Moreover, incidence and mortality rates in females aged 30 years or under have recently increased.It is necessary to develop effective policy to reduce both incidence and mortality, particularly in younger age groups.

Cervical cancer is a well-known preventable cancer worldwide. Many countries including Korea have pursued the positive endpoint of a reduction in mortality from cervical cancer. Our aim is to examine changing trends in cervical cancer incidence and mortality after the implementation of a national preventive effort in Korea. Cervical cancer incidence data from 1999 to 2011 and mortality data from 1983 to 2013 were collected from the Korean Statistical Information Service. Yearly age-standardized rates (ASR) per 100,000 were compared using two standards: the 2005 Korean population and the world standard population, based on Segi's world standard for incidence and the World Health Organization for mortality. In Korea, the age-standardized incidence of cervical cancer per 100,000 persons declined from 17.2 in 2000 to 11.8 in 2011. However, the group aged 25 to 29 showed a higher rate in 2011 (ASR, 6.5) than in 2000 (ASR, 3.6). The age-standardized mortality rate per 100,000 persons dropped from 2.81 in 2000 to 1.95 in 2013. In the worldwide comparison, the incidence rates remained close to the average incidence estimate of more developed regions (ASR, 9.9). The decreasing mortality trend in Korea approached the lower rate observed in Australia (ASR, 1.4) in 2010. Although the incidence rate of cervical cancer is continuously declining in Korea, it is still high relative to other countries. Moreover, incidence and mortality rates in females aged 30 years or under have recently increased. It is necessary to develop effective policy to reduce both incidence and mortality, particularly in younger age groups.

Mentions: In Figure 2, each birth cohort is represented at three points, depicting the incidence in 2000, 2005, and 2010. The birth cohort of 1976 to 1980 and the cohort of 1966 to 1970 showed similar incidences at ages 30 to 34 of 13.3 and 13.2 respectively. Older age groups showed higher incidences if they came from earlier birth cohort groups. Specifically, between the ages of 40 and 44, there was a higher incidence of 33.0 in the 1955 to 1960 birth cohort compared to that of 23.0 in the 1966 to 1970 cohort. Likewise, the rate of 35.5 in the 1945 to 1950 cohort was higher than that of 25.4 in the 1955 to 1960 cohort for individuals aged 50 to 54, and the rate of 42.4 in the 1935 to 1940 cohort was higher than that of 26.9 in the 1945 to 1950 cohort for individuals aged 60 to 64.
