摘要
目的:研究共刺激分子B7-H4在前列腺癌中的表达情况及其临床意义。方法:应用免疫组织化学染色,检测B7-H4分子在前列腺癌中的表达情况,并评价其与临床病理特征的关系。结果:前列腺癌组织中B7-H4在胞浆和(或)胞膜弥漫表达,表达量显著高于正常前列腺组织(P<0.05)。B7-H4在临床肿瘤分级较高患者的前列腺癌组织中,表达显著强于临床肿瘤分级较低患者的前列腺癌组织。结论:B7-H4在前列腺癌组织中表达上调,与患者肿瘤分级密切相关。异常表达的B7-H4在肿瘤的发生、进展中起到一定作用,有望成为肿瘤新的诊断和预后判断指标,封闭肿瘤组织中的B7-H4有可能成为肿瘤免疫治疗的新策略。
Objective： To investigate the expression of B7-H4 in prostate cancer tissue and the relationship between the expression and the clinicopathological features.Methods： Immunohistochemical staining was used to detect the expression of B7-H4 in prostate cancer tissue.And the relationship between the expressions and pathology was evaluated.Results： The B7-H4 was diffusely expressed in cytoplasm and/ or membrane of the prostate cancer tissue;the expression was much higher than that in normal prostate tissue（P 0.05）.The expression of B7-H4 in the prostate cancer tissue was higher in patients with higher tumor grade.Conclusion： B7-H4 may be used as an new indicator for the diagnosis and prognosis of prostate cancer and a novel target for immunotherapy.
