The patients were not surgical candidates for medical reasons or patient refusal. Using a respiratory-gated technique, carbon ion therapy was delivered with curative intent using 4 coplanar beam angles. A median dose of 60 GyE (range, 44–64.8 GyE) was delivered to the planning target volume (PTV), with a median daily dose of 15 GyE (range, 3.6–44 GyE). Treatment outcome was analyzed in terms of local control rate (LCR), survival rate, and treatment-related complications. \n\\nResults\nIn total, 34 patients with 44 oligo-recurrent pulmonary lesions were treated with CIRT. Median follow-up period was 23.7 months. The 2- and 3-year actuarial LCRs of the treated patients were 85.4% ± 6.2% and 85.4% ± 6.2%, respectively. Overall survival was 65.1% ± 9.5% at 2 years, and 50.1% ± 10.5% at 3 years. Although survival rates were relatively worse in the subsets of patients aged < 63 years or with early metastasis (< 36 months after resection of primary site), these factors were not significantly correlated with overall survival (P = 0.13 and 0.19, respectively). All treatment-related complications were self-limited, without any grade 3–5 toxicity. \n\\nConclusions\nCIRT is one of the most effective nonsurgical treatments for colorectal lung metastases, which are relatively resistant to stereotactic body radiotherapy. CIRT is considered to be the least invasive approach even in patients who have undergone repeated prior thoracic metastasectomies.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Bio Med Central"}]},"item_8_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"24581481","subitem_relation_type_select":"PMID"}}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1186/1748-717X-9-68","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.ro-journal.com/content/9/1/68"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ro-journal.com/content/9/1/68","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1748-717X","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":"Takahashi, Wataru"}],"nameIdentifiers":[{"nameIdentifier":"466416","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakajima, Mio"}],"nameIdentifiers":[{"nameIdentifier":"466417","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamamoto, Naoyoshi"}],"nameIdentifiers":[{"nameIdentifier":"466418","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamada, Shigeru"}],"nameIdentifiers":[{"nameIdentifier":"466419","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamashita, Hideomi"}],"nameIdentifiers":[{"nameIdentifier":"466420","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakagawa, Keiichi"}],"nameIdentifiers":[{"nameIdentifier":"466421","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsuji, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"466422","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kamada, Tadashi"}],"nameIdentifiers":[{"nameIdentifier":"466423","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高橋 渉","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"466424","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中嶋 美緒","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"466425","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山本 直敬","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"466426","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山田 滋","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"466427","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻 比呂志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"466428","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鎌田 正","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"466429","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":"Carbon ion radiotherapy for oligo-recurrent lung metastases from colorectal cancer: a feasibility study.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Carbon ion radiotherapy for oligo-recurrent lung metastases from colorectal cancer: a feasibility study."}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-06-27"},"publish_date":"2014-06-27","publish_status":"0","recid":"46766","relation_version_is_last":true,"title":["Carbon ion radiotherapy for oligo-recurrent lung metastases from colorectal cancer: a feasibility study."],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:47:51.162074+00:00"}
