AIM OF THE STUDY: Aim of the study was to assess statistical differences of serum levels of HE4 and CA125 between certain endometrial cancer stages, grading and histological types. MATERIAL AND METHODS: A retrospective study of 52 patients admitted to our clinic for a surgical operation because of endometrial cancer was performed. HE4 and CA125 were measured for each patient. The staging was done according to FIGO. The statistical difference of serum levels of tumor markers was analyzed considering different stages, grading and histological types. RESULTS: Most of the patients (92.31%) were post-menopausal. Serum levels of tumor markers were significantly higher among patients with stage IB-IIIC than stage IA, among patients with stages II-III than stage I and among patients with stage IIIC than stage IA-IIIB. Only HE4 was significantly higher among patients with stage IB than stage IA and among patients with grading G2 and G3 than those with G1. Only CA125 was significantly higher among patients with stage IIIA and IIIB than those with stages I and II. There was no statistically significant difference in level of either tumor marker in differentiation of endometrioid from other histological endometrial cancer. CONCLUSIONS: Both tumor markers HE4 and CA125 can be useful additional tools for pre-surgical differentiation between different stages of endometrial cancer. HE4 can predict advanced histological grades. Neither HE4 nor CA125 can differentiate endometrioid from other histological types of endometrial cancer.
