Korean J Fam Med 2022;43(4):225-230.   Published online July 19, 2022

Background
Since the era of “thyroid cancer epidemic,” many Korean academic societies discouraged the use of ultrasonography in healthy individuals and revised the Korean Thyroid Imaging Reporting and Data System to address the overscreening and overdiagnosis issues. This study aimed to evaluate the change in the diagnostic effectiveness of thyroid cancer screening over the last decade.
Methods
This single-center, retrospective observational study analyzed the data of 125,962 thyroid nodules obtained during cancer screening at the health promotion center of Seoul National University Bundang Hospital from 2010 to 2019. Only 327 thyroid cancer cases pathologically confirmed by fine-needle aspiration (FNA) were included in the study. The strength of the association between the number of FNA and (1) the number of thyroid cancer diagnoses, (2) the positive predictive values (PPVs), and (3) the difference in PPV from the previous year were evaluated using Pearson’s correlation analysis.
Results
The number of thyroid FNA biopsies as well as the thyroid cancer diagnoses decreased from 2010 to 2019 (166 to 48 [-71.1%] vs. 43 to 22 [-48.8%]). The PPV of FNA biopsies increased from 25.9% to 45.8% (+76.8%) and was negatively correlated with the number of FNA biopsies performed (R=-0.87, P<0.001). The difference in PPV from the previous year increased similarly but without statistical significance (R=-0.59, P=0.09).
Conclusion
The diagnostic efficiency of thyroid cancer screening has increased over the last decade, as evidenced by the increasing PPV of FNA biopsies.

Healthy Beliefs regarding Breast Cancer Screening in Iranian Women Health Volunteers: A Path Analysis
Fatemeh Salmani, Mitra Moodi, Azam Yousefi, Ensiyeh Norozi
Korean J Fam Med 2021;42(2):132-139.   Published online May 28, 2020
DOI: https://doi.org/10.4082/kjfm.20.0001
Background
In Iran, 82% of breast cancer cases are diagnosed in late stages, resulting in low survival rates. In the present study, the Stages of Change Theory and Health Belief Model were used as theoretical frameworks for assessing Women Health Volunteer readiness to act on different breast cancer screening behaviors.
Methods
A total of 1,410 Women Health Volunteers were enrolled in this cross-sectional study. The breast self-examination (BSE) and mammography stages of change were measured independently. A standardized questionnaire based on the Health Belief Model was used to assess their beliefs about breast cancer screening methods. A path analysis using PASW SPSS ver. 18.0 (SPSS Inc., Chicago, IL, USA) was used to test the effects of individual beliefs on breast cancer screening stages of change.
Results
Most participants were classified in the pre-contemplation stage of breast cancer screening behaviors. Perceived barriers, benefits, and susceptibility emerged as BSE stages of change predictors. No beliefs were significant mammography stages of change predictors.
Conclusion
Iranian Women Health Volunteers had a very low adherence to common BSE and mammography practices. Healthy beliefs have a strong association with the stages of change for performing BSE, but not for mammography. The impact of health beliefs on an individual’s readiness to act on different breast cancer screening methods may vary with respect to the type of screening method.

Breast and Cervical Cancer Screening Behavior in Female Cancer Survivors: The Korea National Health and Nutrition Examination Survey, 2007–2012
Eun-Ae Lee, Jinyoung Shin, Eun-Joo Hwang, Jung-Woong Lee
Korean J Fam Med 2017;38(3):116-121.   Published online May 23, 2017
DOI: https://doi.org/10.4082/kjfm.2017.38.3.116
Background

The aim of this study was to compare breast and cervical cancer screening rates between female cancer survivors and a population without cancer to identify factors related to cervical and breast cancer screening in cancer survivors.

Methods

We included 17,765 adults (738 cancer survivors and 17,027 individuals without cancer) in this study, all of whom who were 30 years of age or older and participated in the Fourth and Fifth Korean National Health and Nutritional Examination Surveys from 2007–2012. Multiple logistic regression analysis was performed to identify factors related to cervical and breast cancer screening uptake in female cancer survivors.

Results

The screening rate for breast cancer was 56.6%, which was higher than that in the non-cancer control group (P=0.001). The screening rate for cervical cancer was 51.4%, which was not different from that of the non-cancer control group. In terms of breast cancer screening, cancer survivors showed no significant difference in the rate of screening 5 years after their cancer diagnosis. However, cervical cancer survivors were less likely to have cervical cancer screening 10 years after their cancer diagnosis. There was no significant association between cancer screening and sociodemographic factors.

Conclusion

Breast and cervical cancer screening rates in Korean female cancer survivors are low. Secondary primary cancer screening of female cancer survivors needs to be planned in a comprehensive manner, with the consideration of influences beyond sociodemographic factors.

Background

We investigated the association between socioeconomic status (SES) and cancer screening in a Korean population aged 40 years or older.

Methods

This cross-sectional study included 12,303 participants (5,284 men and 7,019 women) who participated in the 2010–2012 Korean National Health and Nutrition Examination Survey. Self-reported questionnaires were used to assess participant's SES (household income, occupational, and educational status) and cancer screening behavior.

Results

Compared to the lowest household income group, the odds ratios (ORs) (95% confidence intervals [CIs]) for overall cancer screening of the highest income group were 2.113 (1.606–2.781) in men and 1.476 (1.157–1.883) in women; those for private cancer screening of the highest income group were 2.446 (1.800–3.324) in men and 2.630 (2.050–3.373) in women, while those for National Cancer Screening Programs (NCSP) in the highest income group were 1.076 (0.805–1.439) in men and 0.492 (0.388–0.623) in women. Compared to manual workers, ORs (95% CIs) for private cancer screening of office workers were 1.300 (1.018–1.660) in men and 0.822 (0.616–1.098) in women. In comparison to the least educated men, OR (95% CI) for private cancer screening of the most educated men was statistically significant (1.530 [1.117–2.095]).

Conclusion

Higher economic status was associated with higher rates of overall and private cancer screening in both sexes and a lower rate of NCSP in women. Male office workers and more educated individuals underwent private cancer screening at a higher rate than manual workers and less educated individuals, respectively.

Comparison of the Quality of Bowel Preparation for Double Contrast Barium Enema According to Remind Calls: A Double-Blind Clinical Trial.
Mi Ji Lee, Myung Ju Oh, Jae Sang Lee, Ji Young Park, Woo Kyung Bae, Belong Cho
Korean J Fam Med 2010;31(9):697-702.   Published online September 20, 2010
DOI: https://doi.org/10.4082/kjfm.2010.31.9.697
Background
Adequate bowel preparation is essential for accurate double-contrast barium enema (DCBE) examination. Several protocols have been performed including controlled diet, split dosage of cathartic, fasting dinner 1 day before the exam. The aim of this study was to compare the effect of remind calls on the quality of bowel preparation. Methods: We conducted a clinical trial for 248 subjects who did DCBE at the health promotion center of a single hospital. One hundred and seven patients received instructions and remind calls one day before starting bowel preparation, and the others received only instructions. Two specialized radiologists rated the quality of bowel preparation on a scale of excellent/good/fair/poor. In addition, we collected data for age, sex, education, income, and the reason for the exam with a detailed questionnaire. Results: The basal characteristics of subjects between 'remind call' and 'no remind call' groups were similar except age (57.0 ± 9.8 years, 54.4 ± 8.1 years, respectively P = 0.021). The proportion of 'excellent' was higher in the 'remind call' group (35.5%) than in the 'no remind call' group (23.4%) with statistical significance (P = 0.037). The adjusted odds ratio was 2.015 for 'remind calls' (P = 0.017), and 0.958 for age (P = 0.011). Conclusion: Remind calls and age were associated with the quality of bowel preparation. Remind calls increased the proportion of 'excellent' quality of bowel preparation, which can help accurate assessment.
