To compare the results of carbon ion radiotherapy with those of surgical series in literature.\nMethods: Between 1996 and 2007, 95 patients with sacral chordoma were included in the phase I/II and phase II study of carbon ion radiotherapy for unresectable bone and soft tissue sarcomas. 68 males and 27 females. Median age 66 years (30-85). 84 patients with primary and ll patients with post operative recurrent tumor. Total dose of 52.8 to 73.6 GyE \nResults: 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 5 years (88%) patients with sacral chordoma treated by carbon ion radiotherapy is better than those in reported data on patients treated by surgical resection with/without adjuvant radiotherapy. 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.\nConclusions: Carbon ion therapy is suggested to be an effective and safe treatment for sacral chordomas, but further experience and longer follow up are 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":"第５回日本粒子線治療臨床研究会","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":"鎌田, 正"}],"nameIdentifiers":[{"nameIdentifier":"622411","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鎌田 正","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"622412","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":"脊索腫に対する炭素イオン線治療","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"脊索腫に対する炭素イオン線治療"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-03-30"},"publish_date":"2009-03-30","publish_status":"0","recid":"63018","relation_version_is_last":true,"title":["脊索腫に対する炭素イオン線治療"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:24:07.953147+00:00"}
