Summary
This summary is machine-generated.Para-aortic lymph node metastasis is uncommon in early endometrial cancer. High-risk features like non-endometrioid histology and lymphovascular invasion predict metastasis, guiding surgical decisions for lymphadenectomy.
Area Of Science
- Gynecologic Oncology
- Surgical Pathology
- Cancer Staging
Background
- Lymph node status is critical for surgical staging and prognosis in endometrial cancer (EC).
- Identifying predictors of para-aortic lymph node (PAN) metastasis is crucial for refining surgical strategies.
Purpose Of The Study
- To identify predictors of PAN metastasis in EC patients.
- To evaluate survival outcomes associated with PAN metastasis.
- To inform surgical lymphadenectomy strategies for EC.
Main Methods
- Retrospective analysis of 713 EC patients undergoing comprehensive staging surgery (July 2016 - July 2019).
- Collected clinical, pathological, and follow-up data.
- Utilized univariate/multivariate logistic regression and Kaplan-Meier analysis.
Main Results
- 9.8% of patients had lymph node metastasis; 6.0% had PAN involvement.
- Independent predictors of PAN metastasis included lymphovascular space invasion (LVSI), pelvic lymph node (PLN) metastasis, and elevated CA125.
- Non-endometrioid histologies, especially serous carcinoma, showed higher PAN involvement rates.
Conclusions
- PAN metastasis is rare in low-risk EC, potentially allowing omission of routine dissection.
- Para-aortic lymphadenectomy is essential for high-risk patients (non-endometrioid histology, LVSI, PLN metastasis, high CA125).
- Uterine serous carcinoma presents frequent nodal spread and poorer survival outcomes.
