乳腺浸润性导管癌X线表现、病理与分子生物学标记关系的研究

Study on correlation of mammographic features、pathology and molecular bology of breast infiltrating ductal carcinoma

目的 探讨乳腺浸润性导管癌（IDC）X线表现、病理与分子生物学标记之间的关系.方法 分析93例经乳腺X线检查、手术及病理证实的IDC患者的X线表现,术后标本应用免疫组化染色测定癌细胞雌激素受体（ER）、孕激素受体（PR）、癌基因（C-erbB-2）的表达情况,并分析与X线表现之间的关系.结果 93例IDC中,癌肿毛刺状边缘与癌细胞ER阳性表达之间呈正相关（P〈0.05）;癌肿钙化与C-erbB-2阳性表达之间呈正相关（P〈0.05）,而与癌细胞ER和PR阳性表达水平之间呈负相关（P〉0.05）;淋巴结转移与癌细胞ER和PR阳性表达之间呈正相关（P〈0.05）,C-erbB-2阳性表达率与有无淋巴结转移及病理组织学分级有关（P〈0.05）.结论 IDC的X线表现、病理与癌细胞ER、PR、C-erbB-2异常表达有一定的相关性,X线表现可以粗略推测ER、PR及C-erbB-2表达情况,对预测IDC淋巴结转移及判断预后有重要意义.

Objective To investigate the correlation among mammographic features、pathology and molecu-lar biology markers of breast infitrating ductal carcinoma（IDC） tissues.Methods The mammographic features of 93 cases with IDC confirmed by surgery and histopathology were analyzed retrospectively.The mastectomy specimens of the IDC were stained with immunohistochemistry,and the expression of ER、PR、C-erbB-2 were measured.The rela-tionship between the immunohistochemical pathologic results and mammographic features was analyzed.Results A-mong the 93 cases of IDC,ER positive expression was positively correlated with the spiculate margin of breast cancer （P〈0.05）;C-erbB-2 positive expression was positively correlated（P〈0.05）.Moreover,ER and PR positive expres-sion showed a significant inverse correlation with the calcifying of breast cancer（P〉0.05）;ER and PR positive ex-pression was positively correlated with the transfer of lymph（P〈0.05）;there existed correlation between the positive expression of C-erbB-2 and lymphatic metastasis and pathohistology grade（P〈0.05）.Conclusion There was a pos-itive correlation among IDC mammography、pathology and the abnormal value of ER、PR and C-erbB-2.The X-ray mammography could reflect the diagnosis value of ER、PR and C-erbB-2 roughly,and thadpractical value in determi-ning prognoses and endocrinotherapy.
