摘  要:目的:探讨乳腺浸润性导管癌中碳酸酐酶Ⅸ蛋白表达与纤维灶之间的关系。方法采用免疫组织化学MaxVision法检测167例乳腺浸润性导管癌中雌激素受体( ER )、孕激素受体(PR)、碳酸酐酶Ⅸ的表达,同时镜下观察纤维灶。结果(1)乳腺癌伴纤维灶(45/80,56.3%)病例癌细胞碳酸酐酶Ⅸ阳性率明显高于乳腺癌不伴纤维灶(25/87,28.7%),差异有统计学意义(P=0.001);乳腺癌伴纤维灶病例中,纤维母细胞碳酸酐酶Ⅸ阳性组(35/40,87.5%)癌细胞碳酸酐酶Ⅸ的表达率明显高于阴性组(10/40,25.0%),二者差异有统计学意义(P<0.001)。(2)乳腺癌伴纤维灶病例中组织学3级病例(23/33,69.7%)的纤维母细胞碳酸酐酶Ⅸ阳性率明显高于(1+2)级(17/47,36.2%),二者差异有统计学意义(P=0.006);纤维母细胞碳酸酐酶Ⅸ阴性组内,ER和PR的阳性率分别为72.5%(29/40)和65.0%(26/40),纤维母细胞碳酸酐酶Ⅸ阳性组中,ER和PR的阳性率分别为50.0%(20/40)和42.5%(17/40),纤维母细胞碳酸酐酶Ⅸ阴性组激素受体的阳性率均明显高于阳性组,二者差异有统计学意义( P=0.04);纤维母细胞碳酸酐酶Ⅸ阴性组的患者年龄明显高于阳性组,二者差异有统计学意义( P=0.002)。纤维母细胞碳酸酐酶Ⅸ阳性组的纤维灶/肿瘤直径比明显大于阴性组,二者差异有统计学意义(P=0.024)。(3)肿瘤最大径≤2 cm组、2 cm<肿瘤最大径≤5 cm组的纤维灶直径均小于肿瘤最大径>5 cm组,差异均有统计学意义( P<0.01)。结论碳酸酐酶Ⅸ的表达与纤维灶有关,纤维灶中的纤维母细胞表达碳酸酐酶Ⅸ还与患者年龄、肿瘤细胞组织学分级、激素受体表达和纤维灶直径/肿瘤直径有关,提示纤维母细胞表达碳酸酐酶Ⅸ可能是乳腺癌�Objective To study the relationship between fibrotic focus ( FF ) and carbonic anhydrase ( CA) Ⅸin invasive ductal carcinomas ( IDC) of the breast.Methods In 167 cases of IDC, the FF was assessed morphologically, and expression of ER, PR and CA Ⅸ was evaluated using MaxVision immunohistochemistry.Results The expression of CAⅨin IDC with and without FF was 56.3%(45/80) and 28.7%(25/87) respectively, with significant difference (P=0.001).In IDC with FF, the CA Ⅸexpression of tumor cells in tumors with CAⅨ-positive fibroblasts (35/40, 87.5%) was significantly (P〈0.001) higher than that in tumors with CAⅨ-negative fibroblasts (10/40, 25.0%).In IDC with FF, the CAⅨexpression of fibroblasts of FF in grade 3 IDC ( 23/33, 69.7%) was significantly ( P =0.006 ) higher than that in grade 1 +2 tumors (17/47, 36.2%).The ER and PR expression of tumor cells in tumors containing CA Ⅸ-negative fibroblasts was 72.5% ( 29/40 ) and 65.0% ( 26/40 ) respectively, whereas the ER and PR expression of tumor cells in tumors containing CAⅨ-positive fibroblasts was 50.0%(20/40) and 42.5% (17/40) respectively; the difference was statistically significant (for both ER and PR, P=0.04 ) .The age of patients with tumors containing CA Ⅸ-negative fibroblasts was significantly ( P=0.002) older than those containing CA Ⅸ-positive fibroblasts.The FF diameter/tumor diameter in tumors containing CA Ⅸ-positive fibroblasts was significantly larger than those containing CA Ⅸ-negative fibroblasts.(3) For the groups of tumor size≤2 cm and tumor size between 2 cm to 5 cm, the diameter of the fibrotic focus was significantly (P〈0.01) smaller than the fibrotic focus size of tumors 〉5 cm in size. Conclusions CA IX expression is correlated with FF, and that in fibroblasts of FF correlated with patients′age, tumor grade, hormone receptors and FF diameter/tumor diameter.CAⅨexpression in FF might be a marker for poor prognosis in patients with bre
