Abstract
OBJECTIVES
This study aimed to investigate socioeconomic status (SES)-based inequality in colorectal cancer (CRC) screening in Korea. We assessed whether the rates of opportunistic and organized CRC screening differed according to income and education levels.
METHODS
We analyzed data from the Korean National Cancer Screening Survey of 27,654 cancer-free individuals, aged 50-74 years, from 2009 to 2021. The weighted cancer screening rates with trends were estimated with the average annual percentage change using joinpoint regression. Inequality was calculated in both relative and absolute terms, based on a Poisson regression model.
RESULTS
The organized screening rate increased significantly from 22.1% in 2009 to 53.1% in 2020 and 50.6% in 2021, with an average annual change of 8.6% (95% confidence interval [CI], 4.9 to 12.5). In contrast, no significant trend was observed for opportunistic screening. The SES inequality in opportunistic screening uptake was indicated by a slope index of inequality (SII) of 9.74% (95% CI, 6.36 to 13.12), relative index of inequality (RII) of 2.18 (95% CI, 1.75 to 2.70) in terms of education level; and an SII of 7.03% (95% CI, 4.09 to 9.98), RII of 1.81 (95% CI, 1.41 to 2.31) in terms of measured income. Although there was an increasing trend in income inequality, no significant SES inequalities were observed in the overall estimates for organized screening.
CONCLUSIONS
Organized CRC screening is effective in improving the participation rate, regardless of SES. However, significant inequalities were found in opportunistic screening, suggesting room for improvement in the overall equity of CRC screening.
Summary
Korean summary
이번 연구는 한국의 대장암 검진에서 사회경제적 수준에 따른 불평등이 있는지를 분석했다. 국가암검진사업 도입 이래로 2009-2021년 연구기간 동안 공공검진을 통한 대장암 수검률은 지속적으로 증가한 반면, 개인검진의 증가는 관찰되지 않았다. 특히 공공 검진의 경우 소득이나 교육수준에 따른 수검률에 차이는 없는 반면, 개인검진에서는 상당한불평등이 관찰되었다.
Key Message
"The study investigated socioeconomic status (SES)-based inequality in colorectal cancer (CRC) screening in Korea. We found that the introduction of the National Cancer Screening Program for CRC effectively increased the participation rate, regardless of the SES of the individuals throughout the study period. However, significant inequalities were observed in opportunistic screening related to education and income."

Abstract
Established in 2017, the Screening Cohort for Asian Nomadic descendants in China (Scan-China) has benefited over 180,000 members of a multi-ethnic population, particularly individuals of Mongolian descent compared with the general population (Han ethnicity), in the Inner Mongolia Autonomous Region, China. This cohort study aims to evaluate the effectiveness of cancer screening and serve as a real-world data platform for cancer studies. The 6 most prevalent cancers in China are considered—namely, breast, lung, colorectal, gastric, liver and esophageal cancer. After baseline cancer risk assessments and screening tests, both active and passive follow-up (based on the healthcare insurance database, cancer registry, the front page of hospital medical records, and death certificates) will be conducted to trace participants’ onset and progression of cancers and other prevalent chronic diseases. Scan-China has preliminarily found a disproportionately lower screening participation rate and higher incidence/mortality rates of esophageal and breast cancer among the Mongolian population than among their Han counterparts. Further research will explore the cancer burden, natural history, treatment patterns, and risk factors of the target cancers.
Summary
Key Message
- Scan-China is the first and largest electronic health data (EHD)-integrated cancer screening program for the Mongolian ethnicity in Inner Mongolia. - Scan-China aims to evaluate the effectiveness of screening interventions, particularly on ethnic minorities, portray the natural history, explore risk factors and summarize treatment patterns and updated outcomes of prevalent tumors/other chronic diseases. - Scan-China database comprises baseline cancer risk assessment, screening tests results, active follow-up investigation for participants at high risk and EHD-integrated passive follow-up. Data sources for passive follow-up include healthcare insurance database, cancer registry, front page of hospital medical record and death certificates.

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.

Abstract
OBJECTIVES
This study investigated the effect of mammography screening on the long-term survival of breast cancer (BC) patients aged 40 years or older according to their screening history and duration since screening.
METHODS
The study cohort was organized from 3 nationwide databases of the Korean National Cancer Screening Program, the Korean Central Cancer Registry, and death certificates. We included 24,387 women diagnosed with invasive BC or ductal carcinoma in situ in 2008 and 2009 and followed up until December 31, 2019. Cox proportional-hazards regression was used to investigate the effect of BC screening on the risk of death.
RESULTS
Overall, 20,916 of 24,387 patients (85.8%) were alive at the end of the follow-up period (median: 10.5 years). The long-term survival rate was significantly lower in the never-screened group (80.3%) than in the screened group (88.9%) (p<0.001). A 35% reduction in the risk of BC death (hazard ratio [HR], 0.65; 95% confidence interval [CI], 0.60 to 0.70) from screening was observed. A subgroup analysis according to the cancer stage showed 62%, 36%, and 24% lower risks of BC death for the localized stage, regional stage, and distant stage, respectively. Women aged 40-49 years received the least benefit from BC screening (HR, 0.71; 95% CI, 0.62 to 0.81).
CONCLUSIONS
Mammography screening was effective in reducing the risk of BC-specific death in Asian women across all cancer stages. However, this effect was relatively small among women in their 40s, suggesting that more detailed and specialized screening strategies are needed for that age group.

Abstract
OBJECTIVES
This study aimed to investigate the effect of cervical cancer screening by Papanicolaou (Pap) smears on the long-term survival of cervical cancer patients.
METHODS
We constructed a retrospective cohort of 14,903 women diagnosed with invasive cancer or carcinoma in situ in 2008 and 2009 and followed up until December 31, 2019, by using individual-level data from 3 national databases of the Korean National Cancer Screening Program, the Korean Central Cancer Registry, and death certificates. Cox proportional-hazards regression was used to investigate the effect of cervical cancer screening on mortality.
RESULTS
In total, 12,987 out of 14,867 patients (87.4%) were alive at the end of the follow-up period (median: 10.5 years). Screened patients had a 38% lower risk of cervical cancer death than never-screened patients (hazard ratio [HR], 0.62; 95% confidence interval [CI], 0.54 to 0.70). Screening was associated with 59% and 35% lower risks of death, respectively, in screened patients with localized and regional stages. Furthermore, lower HRs among women who received screening were observed in all age groups, especially women aged 50–59 years (HR, 0.54; 95% CI, 0.42 to 0.69). The lowest HR for cervical cancer death was reported among patients screened within the past 2 years (HR, 0.54; 95% CI, 0.47 to 0.63), and the HRs increased with increasing time intervals.
CONCLUSIONS
Pap smear screening significantly reduced the risk of cervical cancer-specific death in Korean women across all cancer stages.

한국은 자궁경부암 발생과 사망을 낮추기 위하여 국가암검진사업으로 자궁경부암 검진을 실시하고 있다. 이 연구는 2008-2009년 자궁경부암 진단을 받은 30세-79세 14,903명을 대상으로 과거 자궁경부세포검진 여부에 따른 장기생존율을 추적 조사하였다. 그 결과 자궁경부암 검진을 받은 환자에서 사망 위험비가 약 38% 낮았으며, 2년 이내에 검진을 받은 환자군에서 사망 위험이 가장 낮았다.
Key Message
The Korean National Cancer Screening Program (KNCSP) has provided cervical cancer screening by Pap smear test. However, the survival, particularly long-term survival of cervical cancer patients, has never been evaluated in the KNCSP. This study reports a significant improvement in the long-term survival of screened cervical cancer patients, which persist in subgroup analysis by cancer stage. Patients who were screened within two years before the diagnosis had the best survival.

Abstract
OBJECTIVES
The coronavirus disease 2019 (COVID-19) pandemic has affected the utilization of healthcare services, including participation in cancer screening programs. We compared cancer screening participation rates for colorectal, gastric, breast, and cervical cancers among participants in the National Cancer Screening Program (NCSP) in 2019 and 2020 to address the potential distraction effect of COVID-19 on cancer screening.
METHODS
Data from the NCSP for 4 cancer types (stomach, colorectal, breast, and cervical) in 2019 and 2020 were used to calculate cancer screening participation rates by calendar month, gender, age group, and geographical region. Monthly participation rates were analyzed per 1,000 eligible individuals.
RESULTS
The screening participation rate decreased in 2020 compared to 2019 for all 4 cancers: colorectal (40.5 vs. 35.3%), gastric (61.9 vs. 54.6%), breast (63.8 vs. 55.8%), and cervical (57.8 vs. 52.2%) cancers. Following 2 major COVID-19 waves in March and December 2020, the participation rates in the 4 types of cancer screening dropped compared with those in 2019. The highest decline was observed in the elderly population aged 80 years and older (percentage change: -21% for colorectal cancer; -20% for gastric cancer; -26% for breast cancer; -20% for cervical cancer).
CONCLUSIONS
After the 2 major COVID-19 waves, the screening participation rate for 4 types of cancer declined compared with 2019. Further studies are needed to identify the indirect effects of the COVID-19 pandemic on cancer patients, such as delayed diagnoses of cancer or excess cancer deaths.

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.

Abstract
OBJECTIVES
This study aimed to validate a simple risk assessment tool for estimating the advanced colorectal neoplasia (ACN) risk at colonoscopy screenings and potential factors relevant for implementing this tool in the Korean population.
METHODS
Our study analyzed data from the Cancer Screenee Cohort Study conducted by the National Cancer Center in Korea. The risk level was assessed using the Asia Pacific Colorectal Screening (APCS) score developed by the Asia-Pacific Working Group on Colorectal Cancer. Logistic regression models were used to examine the associations between colorectal-related outcomes and the risk level by APCS score. The discriminatory performance of the APCS score for various colorectal-related outcomes was assessed using C-statistics.
RESULTS
In 12,520 individuals, 317 ACN cases and 4,528 adenoma cases were found. The APCS tool successfully classified the study population into different risk groups, and significant differences in the ACN rate and other outcomes were observed. The APCS score demonstrated acceptable discrimination capability with area under the curve values ranging from 0.62 to 0.65 for various outcomes. The results of the multivariate logistic regression model revealed that the high-risk group had a 3.1-fold higher risk of ACN (95% confidence interval, 2.08 to 4.67) than the average-risk group. Body mass index (BMI) was identified as a significant predictor of ACN in both multivariate and subgroup analyses.
CONCLUSIONS
Our study highlighted significant differences in colorectal-related screening outcomes by colorectal risk level measured using the APCS score, and BMI could be used to improve the discriminatory capability of the APCS score.
Summary
Korean summary
검진의 위해성을 줄이면서 동시에 이득을 최대화할 수 있는 최적의 검진 프로그램은 암 발생 위험도를 고려하는 것이다. 이 연구는 Asia-Pacific Working Group on Colorectal Cancer에서 제안한 “Asia Pacific Colorectal Screening Score (APCS)”가 한국인에서 대장암 발생 위험도를 선별적으로 잘 구분해 낼 수 있음을 보여주었다. 나아가 대장암의 위험도 점수를 산출하는데 체질량지수가 중요한 예측 변수라는 것을 확인하였고, 한국인에서 대장암 발생 위험도의 변별력을 향상시키기 위해 기존의 APCS에 체질량지수를 추가할 것을 제안하였다.
Key Message
This study highlighted that the Asia Pacific Colorectal Screening Score by the Asia-Pacific Working Group on Colorectal Cancer could successfully classify Korean screenees into different risk groups with acceptable discriminatory capability. Furthermore, our study results also suggest that BMI is a significant predictor of colorectal-related health outcomes, which could be potentially added to the original APCS score for improving its discriminatory power.

Abstract
OBJECTIVES
This retrospective observational study evaluated the distribution of dense breasts by age group among healthy Korean women.
METHODS
Participants were women aged 30 years and older who voluntarily underwent screening mammography between January 2007 and December 2011. Women who received the Breast Imaging Reporting and Data System for mammographic density of 3 or 4 were defined as having dense breasts. The proportion of women with dense breasts (PDB, %) was calculated by dividing the number of participants with dense breasts by the total number of participants.
RESULTS
Among the 231,058 women who participated, 78.15% were classified as having dense breasts. PDB was highest in the youngest age group (PDB=94.87%) and lowest in the oldest age group. The greatest difference in PDB between adjacent age groups was observed in the group aged 60-64 years.
CONCLUSIONS
The results show that the proportion of dense breasts by age group increased in all age groups, except in those aged 35-39 years. These findings suggest an association between the age distribution of dense breasts and trends in breast cancer incidence. Further studies are needed to estimate the change in breast cancer incidence rate by age and the accumulation of fatty breast tissue in Korean women.

Abstract
The role of economic evaluation for medical services can be summarixed as providing objective criteria for rational bgudget allocation. With medical and epidemiologial studies, cost effectiveness analysis of cancer screening will provide evidence for allocating more financial resources for cancer screening. This study reviewed comprehensive literature of cancer screening for cervical cancer and breast cancer. Through the extensive review of the literature, I suggest crucial issues of cancer screening and checkpoints in designing costeffectiveness analyses of cervical and breast cancers. The issues of cervical and breast cancer screening include ages of starting and terminating mass screening, screening interval and frequency, false positive rate, false negative rate, analytical models, and sensitivity analysis. In addition, cost effectiveness analysis of breast cancer should consider effects of screening methods-self examination, clinical examination, and mammography-that varies across different nations on cost effectiveness ratio. Study results of most issues would be relevant for performing cost effectiveness analysis of cancer screening in Korea. However, difference in incidence rate, medical fees and reimbursement by insurance across nations should be considered in designing cost effectiveness analysis.
