Furthermore, carbon ions being heavier than protons provide a higher biological effectiveness, which increases with depth, reaching the maximum at the end of the beam's range. This is an ideal property from the standpoint of cancer radiotherapy. At the National Institute of Radiological Sciences (NIRS), the pioneer clinical study on carbon ion radiotherapy (C-ion RT) was started in 1994 using carbon ions generated by Heavy Ion Medical Accelerator in Chiba (HIMAC). So far, more than 6,000 patients have been treated, where the benefit of C-ion RT over other modalities has been demonstrated for various tumor sites in terms of high local control and survival rates, as well as significant reduction in overall treatment time with acceptable toxicities in most cases. Efficacy of C-ion RT has been also demonstrated in other facilities in the world.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"2nd NIRS-ETOILE Joint Symposium on Carbon Ion Radiotherapy","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Tsujii, Hirohiko"}],"nameIdentifiers":[{"nameIdentifier":"635497","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻井 博彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"635498","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Current Status of Carbon Ion Radiotherapy in Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Current Status of Carbon Ion Radiotherapy in Japan"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-12-08"},"publish_date":"2011-12-08","publish_status":"0","recid":"64459","relation_version_is_last":true,"title":["Current Status of Carbon Ion Radiotherapy in Japan"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:11:22.758548+00:00"}
