The association between serum kynurenine and prognosis was evaluated using the Cox’s proportional hazards regression analysis.\nResults: Patients with HCC had significantly higher values of serum kynurenine than patients without HCC (median: 557.1 vs. 464.2 ng/mL, p<0.001). Five-year survival rates of HCC patients with serum kynurenine ≥900 (n = 65), 600–899 (n = 194), and <600 ng/mL (n = 345) were 30.6%, 47.4%, and 61.4%, respectively (p = 0.001, log-rank test). Multivariate analysis identified serum kynurenine as an independent predictor for prognosis of HCC patients. The hazard ratio of serum kynurenine ≥900, and 600–899 compared with serum kynurenine <600 ng/mL were 1.91 (p<0.001) and 1.37 (p = 0.015), respectively.\nConclusions: A high level of serum kynurenine correlated with poor prognosis of HCC. Serum kynurenine levels may be a novel biomarker to predict the prognosis of patients with HCC. The development of drugs that inhibit kynurenine production is expected to help improve the prognosis of patients with HCC.","subitem_description_type":"Abstract"}]},"item_5_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"長崎大学学位論文 学位記番号:博(医歯薬)甲第1443号 学位授与年月日:令和4年3月18日","subitem_description_type":"Other"},{"subitem_description":"Author: Shigemune Bekki, Satoru Hashimoto, Kazumi Yamasaki, Atsumasa Komori, Seigo Abiru, Shinya Nagaoka, Akira Saeki, Tomoyuki Suehiro, Yuki Kugiyama, Asami Beppu, Tamotsu Kuroki, Minoru Nakamura, Masahiro Ito, Hiroshi Yatsuhashi","subitem_description_type":"Other"},{"subitem_description":"Citation: PLoS ONE, 15(10), art. no. e0241002; 2020","subitem_description_type":"Other"}]},"item_5_description_69":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Nagasaki University (長崎大学), 博士(医学) (2022-03-18)","subitem_description_type":"Other"}]},"item_5_dissertation_number_65":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲医歯薬第1443号"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"121964","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Bekki, Shigemune"}]}]},"item_5_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"PLOS"}]},"item_5_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1371/journal.pone.0241002","subitem_relation_type_select":"DOI"}}]},"item_5_relation_42":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://hdl.handle.net/10069/00041446","subitem_relation_type_select":"HDL"}}]},"item_5_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2020 Bekki et al.
