Can the Determination of HE4 and CA125 Markers Affect the Treatment of Patients with Endometrial Cancer?

The aim of our research was to determine the use of CA125 and HE4 as prognostic factors in patients with different clinical staging of endometrial cancer. Sixty-two patients with advanced endometrial cancer and 287 patients with early stage endometrial cancer participated in the study. Based on the results obtained in the study, the cut-off value for HE4 was established at 186 pmol/l and correlated with the possibility of cytoreductive surgery in patients with recurrent endometrial cancer. Univariate logistic regression revealed that serum concentrations for the median CA125 correlated with DFS (HR = 1.76, = 0.033) and OS (HR = 1.42, = 0.025), while the median of HE4 marker correlated with DFS (HR = 1.96, = 0.015) and OS (HR = 1.83, = 0.004). In the multivariate analysis, a decrease in CA125 level below normal range correlated positively with DFS and OS (HR = 1.45, = 0.026; HR = 1.38, = 0.037). HE4 levels correlated with DFS as follows: values below the normal range (HR = 2.31, = 0.01), and with OS (HR = 1.89, = 0.004). Based on the results obtained in the study, we found that HE4 is a sensitive tool for predicting the risk of recurrence and overall survival in patients with endometrial cancer.
