In this study, we verified the 9th JSCCR for rectal cancer, focusing on the differences with the 8th AJCC. Methods This retrospective analysis involved 212 patients with stage I-III rectal cancer. ND was evaluated using wholemount sections. We evaluated the relapse-free survival of each staging system, and compared the prognostic significance of the different staging systems using the Akaike information criterion (AIC) and Harrell's concordance index (c-index). Results Main or lateral lymph node metastasis was detected in nine of 212 (4%) patients. ND was detected in 79 of 212 (37%) patients. The best risk stratification power was observed in the 9th JSCCR (AIC, 759; c-index, 0.708) compared with the 7th JSCCR (AIC, 771; c-index, 0.681), 8th JSCCR (AIC, 768; c-index, 0.696), and the 8th AJCC (AIC, 766; c-index, 0.691). Conclusions The 9th JSCCR, which includes the concepts of jN3 and ND, is useful for the risk stratification of rectal cancer, and the contributes to precise decision-making for follow-up management and adjuvant therapy.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_6_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Surgery today. 2020, 50(11), 1443-1451.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_6_description_53":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_description":"新大院博(医)第1072号","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_6_dissertation_number_52":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第5002号"}]},"item_6_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1007/s00595-020-02024-4","subitem_relation_type_select":"DOI"}}]},"item_6_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© Springer Nature Singapore Pte Ltd. 2020","subitem_rights_language":"en"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Arabiki, Michiru","creatorNameLang":"en"},{"creatorName":"荒引, みちる","creatorNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-07"}],"displaytype":"detail","filename":"r3nmk1072.pdf","filesize":[{"value":"1.51MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","objectType":"fulltext","url":"https://niigata-u.repo.nii.ac.jp/record/2000858/files/r3nmk1072.pdf"},"version_id":"f6d7d478-7c36-414a-96c0-dea8f4beabe2"},{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-07"}],"displaytype":"detail","filename":"r3nmk1072_a.pdf","filesize":[{"value":"558KB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"要旨","objectType":"abstract","url":"https://niigata-u.repo.nii.ac.jp/record/2000858/files/r3nmk1072_a.pdf"},"version_id":"4f7382b2-1a58-417b-9694-ca94e98874b4"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Rectal cancer","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"The Japanese staging system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Whole-mount section","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"TNM classification","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Akaike information criterion","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Verification of the Japanese staging system for rectal cancer, focusing on differences with the TNM classification","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Verification of the Japanese staging system for rectal cancer, focusing on differences with the TNM classification","subitem_title_language":"en"},{"subitem_title":"日本における直腸癌の臨床病期の検証 : TNM分類との違いに着目して","subitem_title_language":"ja"}]},"item_type_id":"6","owner":"1","path":["455","562"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-07"},"publish_date":"2023-03-07","publish_status":"0","recid":"2000858","relation_version_is_last":true,"title":["Verification of the Japanese staging system for rectal cancer, focusing on differences with the TNM classification"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-07T06:31:53.921587+00:00"}
