Evaluation of factors influencing lymph node metastasis in endometrial cancers: A retrospective study.

Lymphovascular invasion, nonendometrioid histology and parametrial involvement are independent predictors of lymph node metastasis in endometrial cancer. Risk models using these risk factors can better predict the risk of nodal metastasis and thus avoid lymph node dissection in low risk patients. Our risk models had reasonably good sensitivity in nodal metastasis prediction and require further validation.
