「がん」と「自殺」の両テーマを主題とした研究動向―PubMedによる国際誌を対象にした学術発表タイトル分析―

抄録

The purpose of this study is to investigate research trends related to "cancer" and "suicide" from the titles of academic publications on both topics published in PubMed. The analysis methods are publication trends, word frequency analysis, and contrast by word frequency analysis. In the contrast by word frequency analysis, articles were categorized into those published before 2000 and those published after 2001, and a chi-square test was conducted. The results showed that there were more studies on suicide in cancer cells, such as apoptosis, before 2000, and more studies on suicide in cancer patients after 2001. Research on both "cancer" and "suicide" used to be dominated by biological aspects such as gene analysis. However, it was thought that the research area has since shrunk, and there has been a transition to a research area centered on psychiatry and psychology.
