The media are a frequent and sometimes sole source of cancer information for many people. News coverage of cancer can be influential to cancer-related practices such as prevention or detection behaviors, and sources cited by journalists may be influential in shaping this coverage. A content analysis (n = 3,656 stories) revealed that the most frequently cited sources in cancer news articles-research institutions and medical journals-receive disproportionately more attention compared to the National Cancer Institute (NCI), the American Cancer Society (ACS), and pharmaceutical companies. Research institutions were cited twice as frequently as medical journals, and more than three times as frequently as pharmaceutical companies. Most clinical trial stories were optimistic or neutral in tone, and tone was significantly related to citations of pharmaceutical companies and medical journals. Implications for effects of cancer coverage on behaviors, and the influence of sources such as research institutions and pharmaceutical companies, are discussed.
媒体是许多人获取癌症信息的常见来源，有时甚至是唯一来源。新闻报道的癌症信息可能会对癌症预防或检测等相关行为产生影响，而记者引用的来源可能会影响新闻报道的内容。一项内容分析（n=3656 篇文章）显示，在癌症新闻文章中，最常被引用的来源——研究机构和医学期刊——与美国国家癌症研究所（NCI）、美国癌症协会（ACS）和制药公司相比，获得了不成比例的更多关注。研究机构的引用频率是医学期刊的两倍，是制药公司的三倍多。大多数临床试验报道的语气是乐观或中立的，语气与制药公司和医学期刊的引用显著相关。本文讨论了癌症报道对行为的影响，以及研究机构和制药公司等来源的影响。
