  • Japanese value set for the EORTC QLU-C10D

    Open Access•Takeru Shiroiwa, Madeleine King et al.•ARTICLE•Quality of Life Research•2024

    The Japan-specific QLU-C10D value set is suitable for evaluating the cost and utility of oncology treatments for Japanese health technology assessment and decision-making

  • Factors contributing to the ceiling effect of the EQ-5D-5L

    Open Access•Hideki Murasawa, Takayuki Sugiyama et al.•ARTICLE•Quality of Life Research•2019

    This study revealed that palliative treatment and two FACT-P physical well-being and PC subscale scores were positively related to CE on the EQ-5D-5L. To our knowledge, this is the first study to examine predictors of CE on the EQ-5D-5L. The present results may be helpful for facilitating the consideration of "bolt-on" studies from the standpoint of PC patients

  • Health utility and health-related quality of life of Japanese prostate cancer patients according to progression status measured using EQ-5D-5L and Fact-P

    Open Access•Hideki Murasawa, Takayuki Sugiyama et al.•ARTICLE•Quality of Life Research•2019

  • Psychometric properties of the Japanese version of the EQ-5D-Y by self-report and proxy-report

    Open Access•Takeru Shiroiwa, Takashi Fukuda et al.•ARTICLE•Quality of Life Research•2019

    The EQ-5D-Y demonstrates reliability and validity among children/adolescents and their parents in Japan. Construct validity of the EQ-5D-Y by self-report was confirmed through comparisons with the PedsQL. Proxy responses to the EQ-5D-Y were more reliable compared to the self-report results, but construct validity was not confirmed in the proxy version

  • Long-term health status as measured by EQ-5D among patients with metastatic breast cancer

    Open Access•Takeru Shiroiwa, Takashi Fukuda et al.•ARTICLE•Quality of Life Research•2016

    Our findings suggest that the EQ-5D index value was higher in patients treated with S-1 during first-line chemotherapy. Considering non-inferiority of S-1 in terms of OS, obtained quality-adjusted life years may be greater in the S-1 arm

  • Japanese population norms for preference-based measures

    Open Access•Takeru Shiroiwa, Takashi Fukuda et al.•ARTICLE•Quality of Life Research•2015

    The Japanese population norms of three preference-based QOL measures were examined for the first time. Such information is useful for economic evaluations and research examining QOL score

  • Verification of the psychometric properties of the Japanese version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 15 palliative (EORTCQLQ-C15-PAL…
