Lymph node recurrence from colorectal cancer without distant metastasis was confirmed by computed tomography, magnetic resonance, and carbon-11 methionine positron emission tomography findings. The subsite distribution was paraaortic area, 59% (n=20); iliac, 26% (n=9); mediastinal, 9% (n=3); inguinal, 3% (n=1); and aortoiliac, 3% (n=1).  Twenty-one of 26 patients had undergone multimodality therapy for locoregional and/or metastatic recurrence. The median age was 55 years (range, 38-85). The doses were escalated from 48GyE to 52.8GyE and were delivered in 12 fractions/3weeks. The median follow-up period was 16.8 months.\nResults: All patients completed the scheduled treatment course. No patient experienced acute or late morbidity of grade 3 or higher. Tumor response was evaluated in 34 lesions. Complete response (CR) was observed in 14 lesions and partial response (PR) in 13. Two lesions remained stable disease. The overall tumor response rate (CR+PR) was 79%. Remarkable anti-tumor effects were observed. The local control rates were 91% and 72% at 1 year and at 3 years, respectively. There is no local recurrence in the lesions receiving 50.4GyE or more. The overall survival rates were 90% and 62% at 1 year and at 3 years, respectively. \nConclusions: Carbon ion radiotherapy seems to be a safe and effective modality in the management of lymph node recurrence from resected colorectal cancer, providing good local control and offering a survival advantage without unacceptable morbidity.","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":"ASTRO 52nd 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":"Shinoto, Makoto"}],"nameIdentifiers":[{"nameIdentifier":"690403","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamada, Shigeru"}],"nameIdentifiers":[{"nameIdentifier":"690404","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasuda, Shigeo"}],"nameIdentifiers":[{"nameIdentifier":"690405","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Imada, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"690406","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kamada, Tadashi"}],"nameIdentifiers":[{"nameIdentifier":"690407","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsujii, Hirohiko"}],"nameIdentifiers":[{"nameIdentifier":"690408","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"篠藤 誠","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"690409","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山田 滋","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"690410","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"安田 茂雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"690411","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"今田 浩史","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"690412","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鎌田 正","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"690413","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻井 博彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"690414","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":"Clinical Results of Carbon Ion Radiotherapy for Lymph Node Recurrence from Resected Colorectal Cancer","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Clinical Results of Carbon Ion Radiotherapy for Lymph Node Recurrence from Resected Colorectal Cancer"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-11-09"},"publish_date":"2010-11-09","publish_status":"0","recid":"70314","relation_version_is_last":true,"title":["Clinical Results of Carbon Ion Radiotherapy for Lymph Node Recurrence from Resected Colorectal Cancer"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:04:22.238512+00:00"}
