OBJECTIVE: To investigate the value of serum human epididymis protein 4 (HE4) in differential diagnosis of patients with low-grade serous (LGSC) and high-grade serous carcinoma (HGSC) serous ovarian cancer.
METHODS: LGSC and HGSC serous ovarian cancer were diagnosed by the two-tier grade system, serum levels of HE4 and carbohydrate antigen 125 (CA125) were measured by ELISA and radioisotope method, respectively in 60 serous ovarian cancer patients. HE4 and TP53 protein in cancer tissue were measured by immunohistochemical method.
RESULTS: The difference in density of HE4 and TP53 protein was significant between LGSC and HGSC tissue, while serum CA125 did not show significant difference between different serum samples. There was significant difference in serum HE4 levels between LGSC and HGSC, and the result was different within FIGO (I+II) stage, suggesting HE4 was not a reliable biomarker for the discrimination between LGSC and HGSC. HE4 had potential as a biomarker for the discrimination between LGSC and HGSC but the role in early diagnosis was limited.
CONCLUSIONS: HE4 may be a reliable marker for differential diagnosis of LGSC and HGSC. But its role in early diagnosis of LGSC and HGSC need to be confirmed from the perspective of two-tier grade system.
