OBJECTIVE: To explore the relationship of lymph node ratio (LNR) and other lymph node parameters with disease-free (DFS) and overall (OS) survival among women with endometrial cancer.
METHODS: Retrospective analysis of data of women diagnosed with endometrial cancer at Hacettepe University Hospitals, Ankara, Turkey, between 2003 and 2013. Women who had their surgical procedure, pathology review, and follow-up at Hacettepe University Hospitals were included in the study. Receiver operator characteristic (ROC) curve analysis was used to determine the threshold LNR associated with survival.
RESULTS: Overall, 376 women were included in the study. A higher number of excised metastatic lymph nodes was associated with decreased survival. ROC curve analysis determined a threshold LNR of 0.03. Women with LNR higher than 0.03 had decreased DFS (P<0.001) and OS (P<0.001) relative to those with LNR of 0.03 or lower. LNR of 0.1 was found to be a significant cutoff value for DFS (P=0.023) and OS (P=0.036) among women with at least one metastatic lymph node.
CONCLUSION: LNR may be used as a prognostic tool in endometrial cancer. Future studies will help to define a precise threshold of LNR in order to implement this prognostic factor in daily practice.
