Human leukocyte antigen-G (HLA-G) expression has been reported to be relevant to cancer development and immune tolerance. The purpose of this study was to investigate the correlation between HLA-G expression and disease progression and to assess the use of HLA-G expression as a prognostic immunomarker in epithelial ovarian carcinoma. Human leukocyte antigen-G expression in 41 ovarian cancer tissues and 8 normal ovarian tissues was analyzed using immunohistochemistry and Western blot assay. Quantitative real-time reverse transcription polymerase chain reaction (RT-PCR) was used for HLA-G messenger RNA (mRNA) expression. Human leukocyte antigen-G mRNA and protein levels were significantly greater in advanced ovarian cancer tissues than in normal or early stage ovarian cancer tissues (P < .05 and P < .05, respectively). Patients with HLA-G expression had a significantly worse prognosis. There is a significant correlation between HLA-G immunoreactivity and patient survival in univariate analysis (P = .04). Our data was consistent with the concept that HLA-G expression might play a pivotal role in the development and disease progression of epithelial ovarian cancer.
