Subjects were 139 patients who underwent neck dissection on 149 sides at our department over a 28-year period between 1975 and 2003 From the 149 sides, a total of 1,862 lymph nodes were removed, an average of 12 5 nodes per side Of the 1,862 nodes, metastasis was confirmed in 172 nodes As for the location of metastatic lymph nodes, levels I, II and III accounted for 90% of the metastatic lymph nodes Based on histological findings at the initial visit, the incidence of metastatic lymph nodes was high for histologically malignant cancer In terms of cumulative survival, factors associated with poor prognosis included three or more metastatic lymph nodes, extranodal invasion, and metastatic lymph nodes at level III or IV. The above findings clarify the mode of metastasis to the cervical lymph nodes, and suggest the possibility that neck dissection for level V involvement can be omitted in some patients Further, as to the timing of neck dissection, there was no marked difference in prognosis between immediate neck dissection or subsequent neck dissection.", "subitem_description_type": "Other"}]}, "item_2_source_id_13": {"attribute_name": "雑誌書誌ID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00017474", "subitem_source_identifier_type": "NCID"}]}, "item_2_text_10": {"attribute_name": "著者所属(英)", "attribute_value_mlt": [{"subitem_text_language": "en", "subitem_text_value": "Second Department of Oral and Maxillofacial Surgery, School of Dentistry, Iwate Medical University"}]}, "item_2_text_2": {"attribute_name": "記事種別(日)", "attribute_value_mlt": [{"subitem_text_value": "研究"}]}, "item_2_text_3": {"attribute_name": "記事種別(英)", "attribute_value_mlt": [{"subitem_text_language": "en", "subitem_text_value": "Originals"}]}, "item_2_text_9": {"attribute_name": "著者所属(日)", "attribute_value_mlt": [{"subitem_text_value": "岩手医科大学歯学部口腔外科学第二講座"}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2003-12-24"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KJ00002373715.pdf", "filesize": [{"value": "1.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensefree": "Creative Commons : 表示 - 非営利 - 改変禁止", "licensetype": "license_free", "mimetype": "application/pdf", "size": 1200000.0, "url": {"label": "KJ00002373715", "url": "https://iwatemed.repo.nii.ac.jp/record/1751/files/KJ00002373715.pdf"}, "version_id": "ed08e0ca-12a3-4002-ae26-9b96b0935e0b"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "head and neck carcinoma", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "cervical lymph node metastasis", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "occult cervical lymph node metastasis", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "radical neck dissection", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "elective neck dissection", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "頭頚部癌の頸部リンパ節転移に関する臨床病理学的研究", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "頭頚部癌の頸部リンパ節転移に関する臨床病理学的研究"}, {"subitem_title": "Clinical and pathological studies on metastasis to the cervical lymph node of head and neck carcinoma", "subitem_title_language": "en"}]}, "item_type_id": "2", "owner": "5", "path": ["119", "401"], "permalink_uri": "https://iwatemed.repo.nii.ac.jp/records/1751", "pubdate": {"attribute_name": "公開日", "attribute_value": "2003-12-24"}, "publish_date": "2003-12-24", "publish_status": "0", "recid": "1751", "relation": {}, "relation_version_is_last": true, "title": ["頭頚部癌の頸部リンパ節転移に関する臨床病理学的研究"], "weko_shared_id": 5}
