Abstract

OBJECTIVES
Since 2002, the Korean government has provided breast cancer screening as part of the National Cancer Screening Program. This study reported trends in the screening rate among Korean women from 2005 to 2020, including organized and opportunistic screening for breast cancer.

METHODS

Data from the Korean National Cancer Screening Survey, an annual cross-sectional nationwide survey, were collected using a structured questionnaire between 2005 and 2020. The study population included 23,702 women aged 40-74 years with no history of cancer. We estimated the screening rate based on the current recommendation of biennial mammographic screening for breast cancer. In addition, a joinpoint trend analysis was performed for breast cancer screening rates among various subgroups.

RESULTS

In 2020, the breast cancer screening rate was 63.5%, reflecting an annual increase of 7.72% (95% confidence interval 5.53 to 9.95) between 2005 and 2012, followed by non-significant trends thereafter. In particular, a significant decrease in the breast cancer screening rate was observed in the subgroups aged 50-59 years old, with 12-15 years of education, and living in rural areas.

CONCLUSIONS

Although there has been substantial improvement in breast cancer screening rates in Korean women, the trend has flattened in recent years. Therefore, continual efforts are required to identify subgroups with unmet needs and solve barriers to the uptake of breast cancer screening.

Summary

Korean summary
본 연구는 2005년에서 2020년까지 암검진수검행태조사 자료를 이용하여 40세 이상의 우리나라 여성의 유방암 검진 수검률이 추이에 대해 분석하였다. 우리나라 유방암 검진 수검률은 2020년 현재 63.5%이다. 하지만 지속적으로 증가하던 유방암 검진 수검률의 추이는 2012년 이후 정체되어 있으며 일부 사회경제적 계층에서는 감소하는 경향을 보였다.

Key Message
In Korea, despite of the high level of breast cancer screening rate, decreasing trends in some socioeconomic classes after 2012. Continual efforts are required to identify subgroup with unmet needs and barriers to the uptake of breast cancer screening.

Abstract

OBJECTIVES
The coronavirus disease 2019 (COVID-19) pandemic has negatively affected every aspect of medical care. However, information regarding the impact of the pandemic on cancer screening is lacking. This study aimed to explore cancer screening changes by geographic region before and during the pandemic in Korea.

METHODS

Korean National Cancer Screening Survey data for 2019 and 2020 were used. Changes in the screening rate before and during the COVID-19 pandemic were calculated by subtracting the rate in 2020 from the rate in 2019. Multivariate logistic regression analyses examined the differences in screening rates at the national and 16 provincial levels before and after the COVID-19 outbreak.

RESULTS

The 1-year screening rates for the four types of cancer decreased during the pandemic (stomach cancer: -5.1, colorectal cancer: -3.8, breast cancer: -2.5, cervical cancer: -1.5%p). In metropolitan areas, the odds of undergoing screening tests during the pandemic were significantly lower than before the pandemic for stomach (adjusted odds ratio [aOR], 0.66; 95% confidence interval [CI], 0.56 to 0.76), colorectal (aOR, 0.63; 95% CI, 0.50 to 0.79), and breast cancers (aOR, 0.75; 95% CI, 0.60 to 0.94). Furthermore, the likelihood of undergoing stomach cancer screening during the pandemic was significantly lower than before the pandemic in non-metropolitan urban areas (aOR, 0.81; 95% CI, 0.70 to 0.94), while it was higher in rural areas (aOR, 1.54; 95% CI, 1.10 to 2.16).

CONCLUSIONS

Since the COVID-19 pandemic, the cancer screening rate has decreased significantly, especially in large cities. Public health efforts are required to improve cancer screening rates.

Summary

Korean summary
• 코로나 대유행 이전과 이후의 최근 1년간 암검진 수검률을 비교한 결과, 위암 (5% 포인트), 대장암 (3.8% 포인트), 유방암 (2.5% 포인트), 자궁경부암 (1.5% 포인트) 수검률이 통계적으로 유의하게 감소하였음 • 특히 위암, 대장암, 유방암의 경우 대도시 지역에서의 수검률이 현저하게 감소하였음

Key Message
The 1-year screening rates for stomach, colorectal, breast, and cervical cancer decreased significantly during the pandemic in Korea, especially in large cities.
