The number of removed pelvic lymph nodes and metastasis status in different anatomical regions was analyzed. The prognostic difference of patients with lymph node involvement stratified by various factors was analyzed by Kaplan\u2013Meier method.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p> The median number of pelvic lymph nodes detected was 22, mainly from obturator (29.54%) and inguinal (21.14%) sites. Metastatic pelvic lymph nodes were found in 192 patients, with obturator accounting for the highest percentage (42.86%). The patients with lymph node involvement in single site had better prognosis that those in multiple sites. The overall- (<jats:italic>P<\/jats:italic>\u2009=\u20090.021) (OS) and progression-free (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001) survival (PFS) curves of patients with inguinal lymph node metastases were worse compared to those with obturator site.

Obturator lymph nodes tended to be involved. The prognosis of patients with inguinal lymph node involvement was poor in contrast to that with obturator LNM. In patients with inguinal lymph node metastases, clinical staging needs to be reconsidered and extended radiotherapy to the inguinal region needs to be strengthened.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00432-023-04810-2","type":"journal-article","created":{"date-parts":[[2023,5,26]],"date-time":"2023-05-26T17:01:54Z","timestamp":1685120514000},"page":"9671-9677","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["The distribution pattern of pelvic lymph nodal metastases in cervical cancer"],"prefix":"10.1007","volume":"149","author":[{"given":"Shangdan","family":"Xie","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xintao","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Hu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guannan","family":"Feng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haiyan","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,5,26]]},"reference":[{"issue":"3","key":"4810_CR1","doi-asserted-by":"publisher","first-page":"576","DOI":"10.1016\/j.ygyno.2020.05.043","volume":"158","author":"V Balaya","year":"2020","unstructured":"Balaya V, Guani B, Benoit L et al (2020) Diagnostic value of frozen section examination of sentinel lymph nodes in early-stage cervical cancer at the time of ultrastaging.
