Serum HE4 is more suitable as a biomarker than CA125 in Chinese women with benign gynecologic disorders.

Objective: This study measured the human epididymis protein 4 (HE4) and CA125 levels in Chinese women with benign gynecological disorders.

Material And Methods: Sera were obtained from Chinese women prior to surgery for a pelvic mass and HE4 and CA125 levels were determined. The proportions of patients with HE4 and CA125 levels were compared.

Results: There were 68 Chinese women with benign diseases. HE4 levels were less elevated than CA125 (1% V.S. 29%, P<0.001). The significant difference was observed in patients with endometriosis/endometriomas in which HE4 was not elevated patients and CA125 was elevated in 53% (P<0.001). Serum HE4 level was not elevated in patients with cystadenoma (0% V.S. 23%, P<0.001) and in patients with germ cell tumors (0% V.S. 5%, P<0.001).

Conclusion: HE4 was less elevated and more suitable as a biomarker than CA125 in chinese women with benign disease.
