First, the patients were enrolled dose-escalation study from 70.4GyE/16 fr. to determine the recommend irradiation-dose with carbon ion radiotherapy. Thereafter, a phase II study was evaluated with the recommend irradiation-dose.\nResults A total of 27 evaluable patients were enrolled. The median follow-up period of survival patients was 29.0 months. As acute adverse effects, grade 3 mucositis was observed in only 1 patient, and there was none with any grade 4 toxicities. As late adverse effects, grade 4 optic nerve injury was observed in 1 patient and grade 3 osteonecrosis were observed in 4 patients. Because the local control rate had been appropriate 100% with the initial dose during phase I study and because it was definitive that more than 70.4 GyE would induce many unacceptable adverse effects from the results of other dose-escalation study with carbon ion in our institution for sarcomas in trunk, we determined that 70.4 GyE/16 fr. was a recommend irradiation-dose for unresectable bone and soft tissue sarcoma in adult head and neck. And we continued the present study with the recommend irradiation-dose as phase II. Overall response rate was 29.6 %, including complete response in 3 patients, partial response in 5 patients. The 1-year and 3-year local control rates were 96.0 % and 91.6%, respectively. The 1-year and 3-year overall survival rates were 92.6% and 72.6%, respectively. The local control rate was significant better than that of our historical result with carbon ion radiotherapy 57.6 or 64.0 GyE/16 fr. for sarcoma in head and neck (log-rank test; p<0.001); however, the results of the present study were not directed at survival duration (log-rank test; p=0.165). \nConclusions The recommend irradiation-dose of carbon ion radiotherapy for bone and soft tissue sarcoma in adult head and neck was 70.4 GyE / 16 fr., and the dose might be fairly effective and safety.","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":"The 51st ASTRO Annual Meeting","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":"Jingu, Keiichi"}],"nameIdentifiers":[{"nameIdentifier":"686774","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mizoe, Junetsu"}],"nameIdentifiers":[{"nameIdentifier":"686775","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hasegawa, Azusa"}],"nameIdentifiers":[{"nameIdentifier":"686776","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Bessho, Hiroki"}],"nameIdentifiers":[{"nameIdentifier":"686777","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsuji, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"686778","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kamada, Tadashi"}],"nameIdentifiers":[{"nameIdentifier":"686779","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsujii, Hirohiko"}],"nameIdentifiers":[{"nameIdentifier":"686780","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"神宮 啓一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"686781","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"溝江 純悦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"686782","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"長谷川 安都佐","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"686783","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"別所 央城","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"686784","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻 比呂志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"686785","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鎌田 正","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"686786","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻井 博彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"686787","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":"Carbon ion radiation therapy improves the prognosis of unresectable bone and soft tissue sarcoma in adult head and neck; results of a phase I/II study","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Carbon ion radiation therapy improves the prognosis of unresectable bone and soft tissue sarcoma in adult head and neck; results of a phase I/II study"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-11-13"},"publish_date":"2009-11-13","publish_status":"0","recid":"69944","relation_version_is_last":true,"title":["Carbon ion radiation therapy improves the prognosis of unresectable bone and soft tissue sarcoma in adult head and neck; results of a phase I/II study"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:08:37.042301+00:00"}
