There were sixty-eight males and 27 females. Median age was 66 years (30-85). Eighty-four patients were presented with primary disease and 11 patients with post operative recurrent tumor. Total dose of52.8 to 73.6 GyE was given in 16 fractions over 4 weeks (4 days a week).\nResults: All patients completed the planned carbon ion radiotherapy. Median survival time was 42 months (13-112). Overall survival rate at 5 years (86%) in patients with sacral chordoma treated by carbon ion radiotherapy is similar to those in reported data on patients treated by surgical resection with/without adjuvant radiotherapy. Local control rate at 5years (88%) in patients with sacral chordoma treated by carbon ion radiotherapy is better than those in reported data. Median time local failure was 35 months (13-60). Four patients treated with a total dose of 73.6 GyE experienced Grade 3/4 skin/soft tissue complications. No other treatment-related surgical interventions including colostomy or urinary diversion were carried out in this series. Fifteen patients required persistent medication for peripheral neuropathy.\nConclusions: Carbon ion therapy is suggested to be an effective and safe treatment for sacral chordomas, but further experience and longer follow-up are still needed.","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":"14th Annual CTOS 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":"Kamada, Tadashi"}],"nameIdentifiers":[{"nameIdentifier":"620892","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Imai, Reiko"}],"nameIdentifiers":[{"nameIdentifier":"620893","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsuji, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"620894","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Serizawa, Itsuko"}],"nameIdentifiers":[{"nameIdentifier":"620895","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Okada, Toru"}],"nameIdentifiers":[{"nameIdentifier":"620896","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鎌田 正","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"620897","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"今井 礼子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"620898","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻 比呂志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"620899","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"芹澤 慈子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"620900","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岡田 徹","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"620901","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 radiotherapy for sacral chordoma","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Carbon ion radiotherapy for sacral chordoma"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-11-19"},"publish_date":"2008-11-19","publish_status":"0","recid":"62857","relation_version_is_last":true,"title":["Carbon ion radiotherapy for sacral chordoma"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:25:57.569157+00:00"}
