Abstract Summary PDF Supplementary Material: Objectives
Accurate and complete cancer staging is essential for effective prognosis and treatment planning. This study investigated the feasibility of enhancing the completeness of tumor‐node‐metastasis (TNM) staging by integrating Surveillance, Epidemiology, and End Results (SEER) Summary Stage data.
Methods
We analyzed data from 5 cancer types (stomach, colorectum, liver, lung, and breast) in Korea (2012-2017). The study assessed the impact of supplementing missing TNM information with SEER Summary Stage data on both staging completeness and 5‐year relative survival rates.
Results
The study included 173 061 stomach cancer, 159 199 colorectal cancer, 89 639 liver cancer, 137 103 lung cancer, and 110 286 breast cancer patients. The percentage of missing TNM stage data varied by cancer type, ranging from 65.1% (breast cancer) to 93.0% (liver cancer). Supplementation significantly reduced missing values—most notably in stomach cancer, where missing data dropped by 50.6 percentage points (%p), followed by liver (21.5%p) and breast cancers (13.6%p). For stomach cancer, supplementation led to a 3.6%p decrease in stage I survival rates, whereas liver cancer exhibited the most pronounced changes, with stage IV survival rates declining from 17.7% to 7.9%.
Conclusions
Integrating SEER Summary Stage data enhances TNM staging completeness. However, further evaluation incorporating treatment information is essential.; Summary

본 연구는 한국 등록통계에서 SEER 요약 병기 데이터를 활용해 TNM 병기 분류 완전성 향상 가능성을 평가하였다. 데이터 보완을 통해 다섯 가지 암종에서 누락률이 최대 50.6%포인트 감소하였으나, 5년 상대 생존율은 대체로 큰 변화가 없었다. 다만 간암 등 일부 암종에서 생존율 변화가 현저하여 치료 정보 등의 추가적인 통합 평가가 필요하다.

Key Message
This study evaluated the feasibility of improving the completeness of tumor-node-metastasis (TNM) staging by integrating Surveillance, Epidemiology, and End Results (SEER) Summary Stage data. Data supplementation significantly reduced the proportion of missing TNM information across five cancer types, including a 50.6 percentage point decrease for stomach cancer, while generally resulting in minimal changes to 5-year relative survival rates. However, notable changes were observed in liver cancer, where stage IV survival rates markedly declined from 17.7% to 7.9%, highlighting the need for further evaluation that incorporates treatment information.

Objectives
Cancer diagnoses have a tremendous impact on individuals and communities, drawing intense public concern. The objective of the current research was to examine news coverage and content related to cancer-related issues in Korean newspapers.
Methods
Primarily using the database system of the Korea Press Foundation, we conducted a content analysis of 2806 articles from 9 Korean daily newspapers during a recent 3-year period from 2015 to 2017. Thematic categories, the types of articles, attitudes and tone, and the number of sources in each article were coded and classified.
Results
Many news articles dealt with a diverse range of themes related to cancer, including general healthcare information, the latest research and development, specific medical institutions and personnel, and technology and products, which jointly accounted for 74.8% of all articles. Those thematic categories differed markedly in terms of article type, tone, and the number of cited sources. News articles provided extensive information about healthcare resources, and many articles seemed to contain advertising content. However, the content related to complex social issues such as National Health Insurance did not include enough information for the reader to contextualize the issues properly or present the issues systematically.
Conclusions
It can be assumed that the media exert differential influence on individuals through news coverage. Within the present reporting framework, the availability and usefulness of information are likely to depend solely on individuals’ capabilities, such as financial and health literacy; this dependency has a negative impact on knowledge gaps and health inequities.

Summary

Korean summary
암과 관련된 최근 3년간(2015년~2017년) 9개 전국 종합일간지의 보도를 한국언론재단 자료를 기반으로 조사 분석한 결과, 2,806개의 뉴스기사에서 일반적 암 정보, 최신 연구개발 소식, 병원 및 의료진 정보, 의료기기 및 신기술 정보 등 다양한 주제를 다루었다. 주제와 함께 기사 형태, 어조, 정보원을 분석한 결과, 암 관련 뉴스기사는 병원 및 의료진, 의료기기 및 신기술 정보를 중심으로 광고성 내용을 함께 포함하는 경우가 많았고, 건강보험 등 복합 분석이 필요한 주제에서는 심층적이고 포괄적인 분석이 드물고 내용을 단순화하는 경향이 있었다. 이러한 뉴스기사의 보도 틀은 암과 관련된 건강 및 질병 문제의 해결을 개인화하고 결과적으로 정보 격차 및 건강 불평등에 부정적 영향을 미칠 수 있다.

Abstract PDF: OBJECTIVE
This study was conducted to assess the distribution of cardiovascular risk factors (serum lipid profiles, BMI, blood pressure, fasting blood sugar) and evaluate the risk profile of CVD by the clustering of the cardiovascular risk factors in school-aged children in the Kyoung-Gi area. METHODS: The study sample consists of 208 11 year-old children (51.4% boys, 48.6% girls) who participated in a cross-sectional screening of cardiovascular risk factors. We surveyed their socio-demographic characteristics, measured the anthropometric variables and analyzed the biochemical markers. RESULTS: Of the cardiovascular risk factors, the percentage risk of the BMI, dyslipidememia and hypertension were highest. The prevalence rates of total cholesterol and LDL-cholesterol in girls was higher than in boys. Also, the associations of the BMI, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides, systolic and diastolic blood pressures were highly significant. In addition, the proportion of subjects with 1, 2, 3 and 4 or more risk factors were 29.3, 12.5, 2.9 and 1.9%, respectively; therefore, a total of 97 subjects (46.6%) had at least one more risk factor. CONCLUSIONS: From these findings, we concluded that the rates of hypercholesterolemia, cardiovascular risk groups and obesity prevalence of these groups were relatively high. These data provide further evidence that the early intervention for cardiovascular health prevention and promotion in school-aged children is necessary at the population level.; Summary
