Platform Building for the Promotion of Cancer and Palliative Care Studies in Japan

在日本，几乎三分之一的死亡是由癌症引起的。为了促进癌症姑息治疗(PCC)的发展，本研究考察了癌症姑息治疗研究所需要的证据水平，并考虑了围绕PCC研究的问题：(1)为了确定日本癌症姑息治疗研究的总体状况，我们对日本以外的出版商接受发表的英文文章进行了内容分析。这些结果表明，缺乏具有更高证据水平的研究论文。(2)使用大规模收据数据库，检索和回顾与医生姑息治疗中阿片类药物使用水平相关的信息。(3)基于这两项研究的结果，我们采访了有姑息治疗经验的医生，以探索需要什么样的研究证据。通过内容分析，提炼出七个关键类别。这一发现表明，日本的临床医生应该得到支持，以促进姑息治疗研究。

In Japan nearly one in every three deaths is caused by cancer. With the intention of promoting palliative care in cancer (PCC), this study examined which level of evidence for PCC research was in demand, and considered issues surrounding PCC research: (1) To ascertain the general state of Japanese PCC research, we conducted content analysis of English articles accepted for publication by the publishers outside Japan. The results suggested lack of research papers with higher levels of evidence. (2) Using large-scale receipt database, we retrieved and reviewed information related to the usage levels of opioid for palliative care by physicians. (3) Based on the findings from the two studies, we interviewed physicians with palliative care experience to explore what kind of research evidence was perceived in need. Through the content analysis, seven key categories were extracted. The findings implied that clinicians in Japan should be rendered supports for promoting palliative care studies.
