Carbon-ion radiotherapy was delivered to 57.6 Gy or 64.0 Gy (RBE) /16 fractions. The clinical factors for the radiation-induced oroantral or oronasal fistula were analyzed using multivariate logistic regression model. \nResults: The median follow up period was 88.8 months. Twenty-three patients (37%) developed the radiation-induced oroantral or oronasal fistula. Multivariate logistic regression analysis showed that the number of the teeth in the volume receiving more than 50 Gy (RBE) was a significant risk factor (odds ratio 2.782). Of the 62 patients, 46 without maxillary invasion were re-analyzed to clarify the effect of the dose-volume factors of the maxilla. The data of maxillary V10-60 and D1-5 were added to the multivariate logistic regression model. Consequently, the number of the teeth in the volume receiving more than 50 Gy (RBE) was a significant risk factor (odds ratio 2.466).\nConclusions: The presence of the teeth was the strongest predictive factor for developing oroantral or oronasal fistula.","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":"H29年度HIMAC共同利用研究成果発表会","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":"小藤, 昌志"}],"nameIdentifiers":[{"nameIdentifier":"656579","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高木, 亮"}],"nameIdentifiers":[{"nameIdentifier":"656580","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"林, 和彦"}],"nameIdentifiers":[{"nameIdentifier":"656581","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"伊川, 裕明"}],"nameIdentifiers":[{"nameIdentifier":"656582","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小藤 昌志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656583","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高木 亮","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656584","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"林 和彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656585","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"伊川 裕明","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656586","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"頭頸部腫瘍に対する炭素イオン線治療後の口腔‐鼻副鼻腔瘻の危険因子に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"頭頸部腫瘍に対する炭素イオン線治療後の口腔‐鼻副鼻腔瘻の危険因子に関する研究"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-04-18"},"publish_date":"2018-04-18","publish_status":"0","recid":"66778","relation_version_is_last":true,"title":["頭頸部腫瘍に対する炭素イオン線治療後の口腔‐鼻副鼻腔瘻の危険因子に関する研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:45:02.413204+00:00"}
