A 34\u2010year\u2010old nulligravid woman with a history of CIN2 was diagnosed with squamous cell carcinoma (4.5\u2009mm width, 4\u2009mm depth) with lymphovascular invasion after conization. Clinical stage was T1a2 (FIGO 2018). Modified\u2010radical trachelectomy with SNNS was planned for fertility preservation. SPECT\u2013CT identified bilateral obturator and left lower para\u2010aortic sentinel nodes. Intraoperative frozen sections revealed a 1.1\u2009mm micrometastasis in the left obturator node and a 2.5\u2009mm macrometastasis in the left para\u2010aortic node. The procedure was converted to modified\u2010radical hysterectomy with bilateral adnexectomy and pelvic lymphadenectomy, followed by concurrent chemoradiotherapy including the para\u2010aortic field. The patient remains disease\u2010free at 10\u2009months. Without SNNS, the para\u2010aortic metastasis would have been undetected, resulting in inadequate radiation coverage. SNNS fundamentally changes therapeutic approaches by enabling accurate disease extent identification and individualized treatment.<\/jats:p>","DOI":"10.1111\/jog.70377","type":"journal-article","created":{"date-parts":[[2026,6,19]],"date-time":"2026-06-19T14:35:11Z","timestamp":1781879711000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Para\u2010Aortic Lymph Node Metastasis Detected by Sentinel Lymph Node Biopsy in Cervical Cancer Initially Presumed to be Stage\n                    <scp>IA2<\/scp>\n                    : A Case Report"],"prefix":"10.1111","volume":"52","author":[{"given":"Hatsune","family":"Ouchi","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology Keio University School of Medicine  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8214-2242","authenticated-orcid":false,"given":"Tatsuyuki","family":"Chiyoda","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology Keio University School of Medicine  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1406-086X","authenticated-orcid":false,"given":"Kensuke","family":"Sakai","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology Keio University School of Medicine  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yutaka","family":"Shiraishi","sequence":"additional","affiliation":[{"name":"Department of Radiology Keio University School of Medicine  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4938-416X","authenticated-orcid":false,"given":"Hiroshi","family":"Nishio","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology Keio University School of Medicine  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wataru","family":"Yamagami","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology Keio University School of Medicine  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,19]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1159\/000527712"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10147-022-02178-w"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1136\/ijgc-2019-000849"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1349-7006.2010.01532.x"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12885-021-07821-9"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ygyno.2024.06.015"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ygyno.2012.08.035"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/cam4.3645"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa2506267"}],"container-title":["Journal of Obstetrics and Gynaecology Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jog.70377","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/jog.70377","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jog.70377","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,6,23]],"date-time":"2026-06-23T03:01:46Z","timestamp":1782183706000},"score":1,"resource":{"primary":{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/10.1111\/jog.70377"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,6]]},"references-count":9,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2026,6]]}},"alternative-id":["10.1111\/jog.70377"],"URL":"https:\/\/doi.org\/10.1111\/jog.70377","archive":["Portico"],"relation":{},"ISSN":["1341-8076","1447-0756"],"issn-type":[{"value":"1341-8076","type":"print"},{"value":"1447-0756","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,6]]},"assertion":[{"value":"2026-02-22","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-06-15","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-06-19","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e70377"}}
