Association of HLA-G expression in cancer lesions with clinicopathological parameters, and HLA-G 14-bp sequence status.

Abbreviations: HLA, human leukocyte antigen-G; HER2, a receptor for human epidermal growth factor; −14 bp, absence of HLA-G 3′UTR 14-bp sequence; +14 bp, presence of HLA-G 3′UTR 14-bp sequence.Data are shown as numbers of cases and percentages.1Comparison of HLA-G expression status between each parameter using the Pearson chi-square test.2The median age of the breast cancer group was 52.0 years.3The modified TNM stage was stratified according to Chen et al. [27].
