Abstract

Objective. We assess the behavior of serum concentrations of HE4 marker in female carriers of BRCA1 and assess the diagnostic usefulness of HE4 in ovarian and endometrial cancer. Methods. A total of 619 women with BRCA1 gene mutation, ovarian, endometrial, metastatic, other gynecological cancers, or benign gynecological diseases were included. Intergroup comparative analyses were carried out, the BRCA1 gene carriers subgroup was subjected to detailed analysis, and ROC curves were determined for the assessment of diagnostic usefulness of HE4 in ovarian and endometrial cancer. Results. Statistically lower serum HE4 and CA 125 levels were observed in BRCA1 gene mutation premenopausal carriers. Occult ovarian/fallopian tube cancer was found 3.6%. Each of those patients was characterized by slightly elevated levels of either CA 125 (63.9 and 39.4 U/mL) or HE4 (79 pmol/L). The ROC-AUC curves were 0.892 and 0.894 for diagnostic usefulness of ovarian cancer and 0.865 for differentiation of endometrial cancer from endometrial polyps. Conclusions. Patients with BRCA1 gene mutations have relatively low serum HE4 levels. Even the slightest elevation in HE4 or CA 125 levels in female BRCA1 carriers undergoing prophylactic surgery should significantly increase oncological alertness. The HE4 marker is valuable in ovarian and uterine cancer diagnosis.
