Thirty-five patients with 35 unresectable muscleskeletal malignant tumors were studied by MET PET at baseline and 11±4 days after completion of carbon radiotherapy. Clinical response ( reduction of tumor size by>50 parsent ) was evaluated after 6 months of therapy using standard imaging tecniques. The reduction of tumor MET uptale (mean±SD) after therapy was significantly different between responding (-49parsent ± 16parsent) and nonresponding tumors \n(-16parsent ± 13parsent). Optimal differentiation was achieved by a cutoff value of 30parsent\nresuction of initial MET uptake. Applying this cutoff value as a criterion for a metaabolic response predicted clinical response with a sensitivity and specificity of 94.1parsent (16of 17 patients) and 94.4parsent (17or 18 patients),respectively. The results of survival rate predicted by MET PET were consistent well with the clinical results. MET PET imaging may differentiate responding and nonresponding tumors early in the carbon ion radiotherapy in patients with muscleskeletal malignant tumors.","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":"第42回日本核医学会総会","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":"Zhang, Hong"}],"nameIdentifiers":[{"nameIdentifier":"594760","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshikawa, Kyosan"}],"nameIdentifiers":[{"nameIdentifier":"594761","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tamura, Katsumi"}],"nameIdentifiers":[{"nameIdentifier":"594762","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tomemori, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"594763","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suhara, Tetsuya"}],"nameIdentifiers":[{"nameIdentifier":"594764","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suzuki, Kazutoshi"}],"nameIdentifiers":[{"nameIdentifier":"594765","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanada, Shuji"}],"nameIdentifiers":[{"nameIdentifier":"594766","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Murata, Hajime"}],"nameIdentifiers":[{"nameIdentifier":"594767","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sasaki, Yasuhito"}],"nameIdentifiers":[{"nameIdentifier":"594768","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsujii, Hirohiko"}],"nameIdentifiers":[{"nameIdentifier":"594769","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"張 宏","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"594770","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉川 京燦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"594771","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田村 克巳","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"594772","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"留森 貴志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"594773","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"須原 哲也","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"594774","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木 和年","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"594775","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"棚田 修二","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"594776","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"村田 啓","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"594777","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐々木 康人","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"594778","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻井 博彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"594779","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":"Initial Study of MET PET to Predict Response to Heavy-lon Radiotherapy in Patients with Muscleskeletal Malignant Tumors","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Initial Study of MET PET to Predict Response to Heavy-lon Radiotherapy in Patients with Muscleskeletal Malignant Tumors"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2003-05-23"},"publish_date":"2003-05-23","publish_status":"0","recid":"59781","relation_version_is_last":true,"title":["Initial Study of MET PET to Predict Response to Heavy-lon Radiotherapy in Patients with Muscleskeletal Malignant Tumors"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T22:01:05.096864+00:00"}
