摘　　要：目的：探讨Hepsin蛋白表达与乳腺浸润性导管癌临床病理相关性。方法采用免疫印迹和免疫组化方法检测正常乳腺8例和乳腺浸润性导管癌139例中Hepsin蛋白表达情况。采用统计学方法分析Hepsin蛋白表达与临床病理的关系。结果免疫印迹和免疫组化方法检测所有乳腺浸润性导管癌样本中98例（70．5％）Hepsin高表达，正常乳腺组织未见明显表达或弱表达。病理分期越晚，Hepsin蛋白表达程度越高；组织分化程度与Hepsin蛋白表达程度呈正相关。结论 Hepsin蛋白表达与乳腺浸润性导管癌进展密切相关，Hepsin蛋白表达与临床分期呈正相关，而与组织分化程度负相关。Objective To investigate the expression of hepsin and its role in the pathogenesis of breast infiltrating ductal cancer （ BIDC） .Methods The expression level of hepsin was examined by immunobloting and immunohistochemistry in breast tissue samples from 8 healthy controls and 139 patients with BIDC,respectively. The correlation between hepsin level and its significance in clinical pathology of BIDC was assessed by statistical analysis.Results High level of hepsin was detected in nearly 70.5 percent of BIDC samples（98 out of 139）by immunobloting and immunohistochemistry , while the level of hepsin was relatively low or hardly detectable in healthy controls.In addition,there was a significant correlation between hepsin level and clinical stages as well as the level of histological differentiation of BIDC .Conclusion Increased expression of hepsin might play an impor-tant role in pathogenesis and progression of BIDC .The level of hepsin is positively correlated to clinical stages of BIDC,but negatively correlated with the level of histological differentiation of BIDC .
