Radiation oncologists contoured the gross tumour volume (GTV), clinical target volume (CTV), spinal cord, duodenum, kidneys, and stomach. The gating duty cycle was set to 30 % around exhalation. FTV and FOAR were calculated using the 4DCT dataset. Planning target volumes (PTV) and planning organs at risk volumes (PRV) were defined as equal to FTV and FOAR, respectively. A dose of 55.2 Gy relative biological effectiveness (RBE) was planned to target the PTV from four beam angles. A single field uniform dose (SFUD) plan was selected. The dose distribution, including intrafractional motion changes, was generated.\n\\n Results\n The mean volume of target receiving 95 % of the planned doses was 96.4 ± 4.1 % to the GTV and 94.7 ± 0.9 % to the CTV. The highest dose to 2 cc of duodenal volume was 27.5 Gy (RBE). The volume of the stomach receiving ⩾30 Gy (RBE) was <7.0 cc in all patients. All metrics for OARs satisfied dose constraints.\n\\n Conclusion\n Dose to the CTV was covered sufficiently by the 4DCT-generated FTV, and dose to OARs was reduced by 4DCT-generated FOAR. This methodology may prevent adverse reactions while preserving local tumour control.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Istituti Editoriali e Poligrafici Internazionali"}]},"item_8_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"27884463","subitem_relation_type_select":"PMID"}}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.ejmp.2016.11.009","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.physicamedica.com/article/S11797(16)30987-5/fulltext"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.physicamedica.com/article/S11797(16)30987-5/fulltext","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1120-1797","subitem_source_identifier_type":"ISSN"}]},"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":"Miki, Kentaro"}],"nameIdentifiers":[{"nameIdentifier":"482917","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mori, Shinichiro"}],"nameIdentifiers":[{"nameIdentifier":"482918","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shiomi, Miho"}],"nameIdentifiers":[{"nameIdentifier":"482919","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamada, Shigeru"}],"nameIdentifiers":[{"nameIdentifier":"482920","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"三木 健太朗","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"482921","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森 慎一郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"482922","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"塩見 美帆","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"482923","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山田 滋","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"482924","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Gated carbon-ion scanning treatment for pancreatic tumour with field specific target volume and organs at risk.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Gated carbon-ion scanning treatment for pancreatic tumour with field specific target volume and organs at risk."}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-07-13"},"publish_date":"2017-07-13","publish_status":"0","recid":"48092","relation_version_is_last":true,"title":["Gated carbon-ion scanning treatment for pancreatic tumour with field specific target volume and organs at risk."],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:32:04.344001+00:00"}
