Abstract
OBJECTIVESCervical cancer is a major disease burden in Vietnam. This study aimed to estimate the incidence and mortality rates of cervical cancer in Vietnam (1999-2017) in comparison to those in Korea, where a population-based cancer registry and national cervical cancer screening program have been implemented.METHODSThe estimated incidence and mortality of cervical cancer in Vietnam and Korea (1999-2017) were collected from Global Burden of Disease 2017 study. Estimated age-standardized rates (ASRs) in both countries were calculated utilizing the 1999-2017 population of each country and the World Health Organization standard population. The reported ASRs in Korea were also computed using data on incidence and mortality (1999-2017) and the Korean population from the Korea Statistical Information Service.RESULTSIn Vietnam, the estimated incidence and mortality of cervical cancer decreased annually by 0.84% and 1.01%. In Korea, the trend of reported incidence showed a dramatic drop (1999-2007 annual percent change [APC], -4.53%) before stably declining (2007-2017 APC, -2.71%). Reported mortality also significantly decreased (2003-2008 APC, -6.63%), and then maintained a stable decline (2008-2017 APC, -3.78%). The incidence and mortality rates were higher in Vietnam than in Korea. The declining trend of incidence and mortality in Vietnam was slower than the corresponding trends in Korea.CONCLUSIONSA national screening program should be implemented for Vietnamese women aged over 30 to maintain, or even hasten, the decline in cervical cancer incidence and mortality. A population-based cancer registry may help monitor the effectiveness of a cervical cancer screening program.
Highlights
The peak age-standardized rates (ASRs) for incidence was in the age group of 55-59 years in both 1999 and 2017
The peak ASR for mortality was found in the age group of 70-74 years in 1999, and in the age group of 75-79 years in 2017
In Korea, the reported incidence and mortality rates significantly declined after the nationwide cancer screening for cervical cancer was initiated in 1999
Summary
Cervical cancer is a globally important health issue, as it is the fourth most frequent cancer among women in terms of both inci-. A reduction in the burden of cervical cancer has been observed in several countries that have successfully implemented nationwide screening programs. Nationwide efforts to implement other prevention programs, such as human papilloma virus (HPV) vaccination programs and reproductive education, Epidemiol Health 2020;42:e2020075 have helped to ease the cervical cancer burden in Korea. The Korean cancer registry provides high-quality data for evaluating the effectiveness of these programs
