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

在日本，几乎每三个死亡中就有一个是由癌症引起的。本研究以推进癌症姑息治疗（PCC）为目的，对PCC研究的证据要求进行了探讨，并对PCC研究的相关问题进行了思考：（1）为了弄清日本PCC研究的总体状况，对日本以外的出版社接受发表的英文论文进行了内容分析。结果表明，缺乏具有更高证据水平的研究论文。(2)使用大规模的收据数据库，我们检索和审查有关阿片类药物的使用水平的姑息治疗的医生的信息。(3)根据这两项研究的结果，我们采访了有姑息治疗经验的医生，以探讨什么样的研究证据被认为是需要的。通过内容分析，提取了七个关键类别。研究结果暗示，临床医生在日本应提供支持，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.
