This study aimed to identify the predictive factors for the rare but important clinical issue of SHNC, namely cervical lymph node metastasis (CLNM), following endoscopic resection. Methods: Sixty-nine patients with SHNC who underwent endoscopic resection were enrolled in the study. Clinical data, preoperative endoscopic findings, pathological findings, and treatment outcomes were retrospectively reviewed. Because the pharyngeal mucosa lacks the muscularis mucosa, we measured tumor thickness in permanent pathology as an alternative to the depth of invasion. Correlations with the occurrence of CLNM were statistically examined. Results: The 5-year disease-specific survival rate was 100%. Of 69 patients, 3 (4.3%) developed CLNM. All had subepithelial but not epithelial tumors. The 0-IIa type in the macroscopic findings, type B2/B3 vessels in narrow-band imaging, tumors ≥ pathological stage T2, lymphatic invasion, positive surgical margins, and tumor thickness >1,000µm showed significant correlations with CLNM following endoscopic resection. Furthermore, the classification of type B vessels was significantly associated with tumor thickness. Conclusion: The treatment outcomes following endoscopic resection for SHNC were favorable. The risk of CLNM following endoscopic resection in SHNC can be predicted by several preoperative endoscopic and postoperative pathological findings. Among them, the classification of type B vessels, which correlated with both tumor thickness and CLNM, might be a useful predictive factor.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_6_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Frontiers in Surgery. 2022, 8, 813260.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_6_description_53":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_description":"新大博(医)第1823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":"乙第2265号"}]},"item_6_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3389/fsurg.2021.813260","subitem_relation_type_select":"DOI"}}]},"item_6_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2022 Okabe, Ueki, Ohashi, Takeuchi, Hashimoto, Takahashi, Shodo, Yamazaki, Matsuyama, Umezu, Terai, Ajioka and Horii.","subitem_rights_language":"en"},{"subitem_rights":"Creative Commons Attribution 4.0 International","subitem_rights_language":"en","subitem_rights_resource":"https://creativecommons.org/licenses/by/4.0/"}]},"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":"Okabe, Ryuichi","creatorNameLang":"en"},{"creatorName":"岡部, 隆一","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":"2023-04-27"}],"displaytype":"detail","filename":"r4nmo1823.pdf","filesize":[{"value":"1.11MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","objectType":"fulltext","url":"https://niigata-u.repo.nii.ac.jp/record/2000977/files/r4nmo1823.pdf"},"version_id":"e62f1a62-5f50-4cac-93c9-175e9930ba8b"},{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-04-27"}],"displaytype":"detail","filename":"r4nmo1823_a.pdf","filesize":[{"value":"258KB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"要旨","objectType":"abstract","url":"https://niigata-u.repo.nii.ac.jp/record/2000977/files/r4nmo1823_a.pdf"},"version_id":"6427f3e3-a490-4fe0-9b02-1e9d734c1324"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"cervical lymph node metastasis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"endoscopic resection","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"superficial head and neck carcinoma","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"classification of type B vessels","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"tumor thickness","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":"Predicting Cervical Lymph Node Metastasis Following Endoscopic Surgery in Superficial Head and Neck Carcinoma","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Predicting Cervical Lymph Node Metastasis Following Endoscopic Surgery in Superficial Head and Neck Carcinoma","subitem_title_language":"en"},{"subitem_title":"頭頸部表在癌における内視鏡治療後の後発頸部リンパ節転移予測因子の検討","subitem_title_language":"ja"}]},"item_type_id":"6","owner":"1","path":["455","562"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-04-27"},"publish_date":"2023-04-27","publish_status":"0","recid":"2000977","relation_version_is_last":true,"title":["Predicting Cervical Lymph Node Metastasis Following Endoscopic Surgery in Superficial Head and Neck Carcinoma"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-04-27T02:15:00.085614+00:00"}
