Factor affecting lymph node metastasis in uterine papillary serous carcinomas: a retrospective analysis
The aim of this study was to investigate the risk factors for lymph node metastasis (LNM) in patients with uterine serous cancer (USC) who underwent systematic staging surgery. Eighty patients who were operated on for pure uterine serous papillary carcinoma between 2008 and 2020 in our clinic were retrospectively analysed. The effects of demographic information and clinicohistopathological characteristics of the included patients on LNM were examined. The median age of the patients included in the study was 64.3 and the tumour diameter was 3.8 cm. At the time of diagnosis, 65.8% of the cases were in the advanced stage, while 34.2% were in the early stage. There was no LNM in 42 (52.5%) of the cases, only pelvic in six (7.5%), only paraaortic LNM in four (5%) patients, and both pelvic and paraaortic LNM in 24 (30%) patients. When factors that may affect LNM were evaluated with multivariate analysis, lymphovascular space invasion (LVSI) and cytology positivity were found to be independent risk factors (
