METHODS AND MATERIALS: This retrospective study analyzed 16 patients with malignant glioma (4 patients, anaplastic astrocytoma; 12 patients, glioblastoma multiforme) treated with surgery and carbon ion radiotherapy from April 2002 to Nov 2005. The MET-PET target volume was compared with gross tumor volume and CTV, defined by using computed tomography/magnetic resonance imaging (MRI). Correlations with treatment results were evaluated between positive and negative extended volumes (EVs) of the MET-PET target for CTV. RESULTS: Mean volumes of the MET-PET targets, CTV1 (defined by means of high-intensity volume on T2-weighted MRI), and CTV2 (defined by means of contrast-enhancement volume on T1-weighted MRI) were 6.35, 264.7, and 117.7 cm(3), respectively. Mean EVs of MET-PET targets for CTV1 and CTV2 were 0.6 and 2.2 cm(3), respectively. The MET-PET target volumes were included in CTV1 and CTV2 in 13 (81.3%) and 11 patients (68.8%), respectively. Patients with a negative EV for CTV1 had significantly greater survival rate (p = 0.0069), regional control (p = 0.0047), and distant control time (p = 0.0267) than those with a positive EV. Distant control time also was better in patients with a negative EV for CTV2 than those with a positive EV (p = 0.0401). CONCLUSIONS: For patients with malignant gliomas, MET-PET has a possibility to be a predictor of outcome in carbon ion radiotherapy. Direct use of MET-PET fused to planning computed tomography will be useful and yield favorable results for the therapy.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.ijrobp.2007.06.071","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0360-3016","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":"Mahasittiwat, Pawinee"}],"nameIdentifiers":[{"nameIdentifier":"447788","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mizoe, Junetsu"}],"nameIdentifiers":[{"nameIdentifier":"447789","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hasegawa, Azusa"}],"nameIdentifiers":[{"nameIdentifier":"447790","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishikawa, Hiroyuki"}],"nameIdentifiers":[{"nameIdentifier":"447791","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshikawa, Kyosan"}],"nameIdentifiers":[{"nameIdentifier":"447792","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mizuno, Hideyuki"}],"nameIdentifiers":[{"nameIdentifier":"447793","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yanagi, Takeshi"}],"nameIdentifiers":[{"nameIdentifier":"447794","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takagi, Ryo"}],"nameIdentifiers":[{"nameIdentifier":"447795","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Pattaranutaporn, Pittyapoom"}],"nameIdentifiers":[{"nameIdentifier":"447796","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsujii, Hirohiko"}],"nameIdentifiers":[{"nameIdentifier":"447797","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"溝江 純悦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"447798","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"長谷川 安都佐","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"447799","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石川 博之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"447800","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉川 京燦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"447801","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"水野 秀之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"447802","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"柳 剛","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"447803","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高木 亮","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"447804","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻井 博彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"447805","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":"L-[methyl-11C] Methionine positron emission tomography for target delineation in malignant gliomas: impact on results of carbon ion radiotherapy.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"L-[methyl-11C] Methionine positron emission tomography for target delineation in malignant gliomas: impact on results of carbon ion radiotherapy."}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-02-14"},"publish_date":"2008-02-14","publish_status":"0","recid":"45094","relation_version_is_last":true,"title":["L-[methyl-11C] Methionine positron emission tomography for target delineation in malignant gliomas: impact on results of carbon ion radiotherapy."],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:07:46.286877+00:00"}
