The current study investigated the complications, functional outcomes, and risk factors of CIRT.\n\nMethods\nOf 112 patients who were treated with CIRT for unresectable pelvic bone sarcoma, the authors enrolled 29 patients who were without local disease recurrence or distant metastasis. The mean follow‐up was 93 months. Complications, functional outcomes, and quality of life scores were assessed. Risk factors were analyzed, including the dose‐volume histogram of the femoral head.\n\nResults\nFemoral head necrosis occurred in approximately 37% of patients, pelvic fractures were reported in 48% of patients, and neurological deficits were noted in 52% of patients. Femoral head necrosis was found to be significantly more prevalent among patients with periacetabular tumors (P = .018). The dose‐volume histogram of the femoral head indicated tolerable volume percentages of the femoral head to be <33% for 40 grays (relative biological effectiveness) and 16% for 60 grays ( relative biological effectiveness). The mean Musculoskeletal Tumor Society score and Toronto Extremity Salvage Score were 53% and 64%, respectively, and the mean EuroQol 5 dimensions questionnaire index was 0.587. Patients aged >50 years and those with periacetabular tumors were found to have significantly lower Toronto Extremity Salvage Scores.\n\nConclusions\nFemoral head necrosis, pelvic fracture, and nerve damage are common complications with the use of CIRT for pelvic bone sarcoma. To prevent femoral head necrosis, the radiation dose to the femoral head should be kept below the estimated tolerance curve presented in the current study. The functional outcome is nearly equivalent to that of surgery. CIRT may be a promising alternative to surgery for patients with unresectable pelvic bone sarcoma.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"ACS"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1002/cncr.33082","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://acsjournals.onlinelibrary.wiley.com/doi/full/10.1002/cncr.33082","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0008-543X","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":"Takenaka, Satoshi"}],"nameIdentifiers":[{"nameIdentifier":"1005995","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Araki, Nobuhito"}],"nameIdentifiers":[{"nameIdentifier":"1005996","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Outani, Hidetatsu"}],"nameIdentifiers":[{"nameIdentifier":"1005997","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ken‐ichiro, Hamada"}],"nameIdentifiers":[{"nameIdentifier":"1005998","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshikawa, Hideki"}],"nameIdentifiers":[{"nameIdentifier":"1005999","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kamada, Tadashi"}],"nameIdentifiers":[{"nameIdentifier":"1006000","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Imai, Reiko"}],"nameIdentifiers":[{"nameIdentifier":"1006001","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nobuhito, Araki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1006002","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tadashi, Kamada","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1006003","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Reiko, Imai","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1006004","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":"Complication rate, functional outcomes, and risk factors associated with carbon ion radiotherapy for patients with unresectable pelvic bone sarcoma","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Complication rate, functional outcomes, and risk factors associated with carbon ion radiotherapy for patients with unresectable pelvic bone sarcoma"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-11-05"},"publish_date":"2020-11-05","publish_status":"0","recid":"80898","relation_version_is_last":true,"title":["Complication rate, functional outcomes, and risk factors associated with carbon ion radiotherapy for patients with unresectable pelvic bone sarcoma"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:21:55.287460+00:00"}
