Abstract
대한민국은 전 세계에서 갑상선암 발생률이 가장 높은 나라이며 특히 여성에서 발생률이 높다. 그런데 갑상선암은 과잉진단의 우려가 높으므로 이를 해결하기 위해서 갑상선암검진에 영향을 미치는 요인들을 파악할 필요가 있다. 선행연구 결과에 의하면 유방암검진을 비롯한 검진경험이 갑상선암검진 여부와 관련이 있었다. 이 연구는 유방암검진 유형과 갑상선암검진의 연관성을 분석하기 위하여 2014년 암검진 수검행태조사 자료를 이용하였다. 분석대상은 암 기왕력이 없는 30세 이상의 여성 2,270명이었다. 통계분석은 유방암검진 요인, 인구학적 요인, 사회경제적 요인, 건강행태 관련 요인과 갑상선암검진의 연관성을 확인하기 위하여 카이제곱검정(chi-square test)을 시행하였다. 또한, 유방암검진 유형과 갑상선암검진의 상관관계를 파악하기 위하여 다중 로지스틱 회귀분석(multiple logistic regression)을 시행하였으며, 모든 독립변수를 보정한 후 오즈비(Odds Ratio, OR)와 95% 신뢰구간(95% Confidence Interval, CI)을 산출하였다. 이 연구에서 우리나라 성인 여성의 2014년 갑상선암검진 수검률은 25.1%였다. 유방암검진 유형에 따라 갑상선암검진 수검률이 달랐는데 유방촬영검사만 받은 경우(OR=1.44, 95% CI=1.03-2.00), 유방초음파검사만 받은 경우(OR=2.68, 95% CI=1.81-3.98), 두 가지 검사를 모두 받은 경우(OR=2.69, 95% CI=1.94-3.73)의 순서로 갑상선암검진을 더 많이 받았다. 그 외에 갑상선암검진과 상관이 있는 요인은 연령, 주관적 건강상태, 암 가족력이었다. 연령은 유방암 발생률이 높은 연령대 순서대로 갑상선암검진을 많이 받았다(50대: OR=2.94, 95% CI=2.10-4.12); 40대: OR=2.59, 95% CI=1.86-3.61; 60대: OR=1.96, 95% CI=1.33-2.91)). 반면에, 주관적 건강상태가 좋은 경우(OR=0.74, 95% CI=0.59-0.93)와 암 가족력이 없는 경우(OR=0.62, 95% CI=-0.48-0.81)는 갑상선암검진을 적게 받았다. 유방암검진 종류에 대한 추가분석 결과 유방초음파검사를 받은 경우는 그렇지 않은 경우보다 갑상선암검진을 많이 받았으나(OR=2.05, 95% CI=1.68-2.50) 유방촬영검사 여부는 유의한 차이가 없었다. 또한, 검진기관 종류에 대한 추가분석 결과 검진전문기관에서 유방초음파검사(OR=2.41, 95% CI=1.45-4.00)나 유방촬영검사(OR=2.04, 95% CI=1.27-3.28)를 받은 경우가 검사를 받지 않은 경우보다 갑상선암검진을 가장 많이 받았다. 이 연구는 유방암검진 유형 특히, 유방초음파검사와 갑상선암검진의 연관성을 국내 최초로 분석했다는 점에서 의미가 있다. 갑상선암은 예후가 극도로 좋기 때문에 고위험군에 한해서 갑상선암검진을 시행하도록 권고되고 있다. 그러므로 연구결과를 토대로 갑상선암검진을 올바로 시행한다면 국민건강 향상과 적정 수준의 의료비 부담을 달성하는 데 도움이 될 것이다.

The incidence rate of thyroid cancer in Korea is the highest in the world, especially among women. However, since it would be likely to make overdiagnosis of thyroid cancer, it is needed to recognize factors that could influence the diagnosis on thyroid cancer. According to precedent research, it has been known that experience of breast cancer screening is associated with thyroid ultrasonography. In order to analyze correlation between types of breast cancer screening and thyroid ultrasonography, this study used the Korea National Cancer Screening Survey (KNCSS) in 2014. It selected 2,270 women who are 30 years old or more and have not been related with any cancers. For statistical analysis, this study performed a chi-square test on each variable in order to determine correlation between thyroid ultrasonography and breast cancer screening, demographic factors, socioeconomic factors, and health-related factors. In addition, in order to identify correlation between types of breast cancer screening and thyroid ultrasonography, this study examined multiple logistic regression, and after adjusting every independent variable this study calculated odds ratio (OR) and 95% confidence interval (CI). The thyroid ultrasonography rate was 25.1% in this research. Depending on the types of breast cancer screening, the rate of taking thyroid ultrasonography was different. Some people were more likely to take thyroid ultrasonography in consecutive order when they took only mammography (OR=1.44, 95% CI=1.03-2.00), when they took only breast ultrasonography (OR=2.68, 95% CI=1.81-3.98), and when they took both mammography and breast ultrasonography (OR=2.69, 95% CI=1.94-3.73). Moreover, the other factors related with the thyroid ultrasonography were age, self-rated health, and family history of cancer. In the case of age, they took much more thyroid ultrasonography in order of age group, which shows the higher risk of cancer incidence. (in their fifties: OR=2.94, 95% CI=2.10-4.12); in their forties: OR=2.59, 95% CI=1.86-3.61; in their sixties: OR=1.96, 95% CI=1.33-2.91)). On the other hand, they took the less thyroid ultrasonography when they answered their self-rated health is good (OR=0.74, 95% CI=0.59-0.93) and they do not have family history of cancer (OR=0.62, 95% CI=-0.48-0.81). As a result of additional analysis on the types of breast cancer screening, if they took breast ultrasonography those people were more likely to take thyroid ultrasonography compared to the others who did not take the breast ultrasonography (OR=2.05, 95% CI=1.68-2.50), but breast cancer mammography did not show significant difference. In addition, as a result of additional analysis on types of examination institution, when they took breast ultrasonography (OR=2.41, 95% CI=1.45-4.00) or breast mammography OR=2.04, 95% CI=1.27-3.28) at the examination-centered institution, those people were most likely to take thyroid cancer screening, compared to the others who did not take the cancer screening. This study has significance because it is the first study analyzing correlation between types of breast cancer screening, which especially focuses on breast ultrasonography, and thyroid cancer screening in Korea. Since prognosis on thyroid cancer is excellent, thyroid ultrasonography is encouraged. Therefore, if thyroid cancer screening is conducted appropriately based on this result, this study would help improve national health and achieve affordable medical cost.
