目的:研究缺氧诱导因子1(HIF-1α)、血管内皮生长因子(VEGF)、环氧化酶-2(COX-2)在乳腺癌中的表达与发生、发展及侵袭转移的关系。方法应用免疫组织化学 S-P 法检测61例乳腺癌前病变患者[25例导管非典型增生(ADH)、36例导管原位癌(DCIS)]和78例乳腺浸润性癌患者(IDC)组织中 HIF-1α、VEGF 和 COX-2的表达情况,并与52例乳腺增生患者标本作为对照。采用 SPSS 17.0软件包,HIF-1α,VEGF 和 COX-2样本阳性率组间比较采用χ2检验。结果(1)HIF-1α、VEGF 和 COX-2在乳腺 IDC 中的阳性表达率分别为67.9%、64.1%和79.5%,明显高于在乳腺癌前病变(DCIS 为44.4%、44.4%、55.6%;ADH 为28.0%、32.0%、36.0%)和乳腺普通导管增生病变(7.7%,23.1%,15.4%)中的表达,差异有统计学意义(χ2=5.696,12.424,28.415;P <0.05);(2)乳腺癌前病变中 DCIS 与 ADH 比较,HIF-1α(χ2=1.699,P>0.05)、VEGF(χ2=0.957,P>0.05)、COX-2(χ2=2.263,P>0.05),差异无统计学意义;(3)HIF-1α、VEGF 和 COX-2在乳腺 IDC 中高表达与患者年龄(χ2=3.410,0.509,0.103;P >0.05)、肿瘤大小(χ2=2.010,0.143,0.304;P >0.05)无关,而与组织学分级(χ2=16.268,15.695,11.272;P <0.05))和淋巴转移(χ2=6.321,13.020,19.123;P<0.05)相关;(4)HIF-1α、VEGF 和 COX-2三者在乳腺癌中的表达呈正相关(r =0.263,χ2=5.412,P<0.05;r=0.436,χ2=9.441,P<0.05)。结论 HIF-1α、VEGF 和 COX-2高表达是乳腺癌发生、侵袭转移行为的重要生物学标志,HIF-1α可能发生在癌变早期阶段,是乳腺癌的早起事件;VEGF 和 COX-2与乳腺癌进展期侵袭转移更相关;HIF-1α、VEGF 和 COX-2联合检测可作为判断乳腺癌预后的指标。
目的:研究缺氧誘導因子1(HIF-1α)、血管內皮生長因子(VEGF)、環氧化酶-2(COX-2)在乳腺癌中的錶達與髮生、髮展及侵襲轉移的關繫。方法應用免疫組織化學 S-P 法檢測61例乳腺癌前病變患者[25例導管非典型增生(ADH)、36例導管原位癌(DCIS)]和78例乳腺浸潤性癌患者(IDC)組織中 HIF-1α、VEGF 和 COX-2的錶達情況,併與52例乳腺增生患者標本作為對照。採用 SPSS 17.0軟件包,HIF-1α,VEGF 和 COX-2樣本暘性率組間比較採用χ2檢驗。結果(1)HIF-1α、VEGF 和 COX-2在乳腺 IDC 中的暘性錶達率分彆為67.9%、64.1%和79.5%,明顯高于在乳腺癌前病變(DCIS 為44.4%、44.4%、55.6%;ADH 為28.0%、32.0%、36.0%)和乳腺普通導管增生病變(7.7%,23.1%,15.4%)中的錶達,差異有統計學意義(χ2=5.696,12.424,28.415;P <0.05);(2)乳腺癌前病變中 DCIS 與 ADH 比較,HIF-1α(χ2=1.699,P>0.05)、VEGF(χ2=0.957,P>0.05)、COX-2(χ2=2.263,P>0.05),差異無統計學意義;(3)HIF-1α、VEGF 和 COX-2在乳腺 IDC 中高錶達與患者年齡(χ2=3.410,0.509,0.103;P >0.05)、腫瘤大小(χ2=2.010,0.143,0.304;P >0.05)無關,而與組織學分級(χ2=16.268,15.695,11.272;P <0.05))和淋巴轉移(χ2=6.321,13.020,19.123;P<0.05)相關;(4)HIF-1α、VEGF 和 COX-2三者在乳腺癌中的錶達呈正相關(r =0.263,χ2=5.412,P<0.05;r=0.436,χ2=9.441,P<0.05)。結論 HIF-1α、VEGF 和 COX-2高錶達是乳腺癌髮生、侵襲轉移行為的重要生物學標誌,HIF-1α可能髮生在癌變早期階段,是乳腺癌的早起事件;VEGF 和 COX-2與乳腺癌進展期侵襲轉移更相關;HIF-1α、VEGF 和 COX-2聯閤檢測可作為判斷乳腺癌預後的指標。

Objective To investigate the expression of HIF-1 α,VEGF and COX-2 in breast carcinoma and their associations with the occurrence,development,invasion and metastasis of breast carcinoma. Methods The expression of HIF-1 α,VEGF and COX-2 was detected by immunohistochemistry S-P method in sixty-one cases of precancerous lesions including twenty-five cases of atypical ductal hyperplasia (ADH), thirty-six cases of ductal carcinoma in situ (DCIS),and seventy-eight cases of invasive ductal carcinoma (IDC)of the breast.Twenty-six cases of hyperplasia breast tissues were selected as control group.The differences of positive rates of HIF-1 α,VEGF and COX-2 were compared with chi-square test.Results The positive rates of HIF-1 α,VEGF and COX-2 in IDC were 67.9%,64.1 % and 79.5% respectively;the positive rates in DCIS were 44.4%,44.4%,55.6% respectively,and the positive rates in ADH were 28.0%,32.0%,36.0% respectively,which were higher than those in hyperplasia breast tissues(7.7%, 23.1 %,1 5.4%,χ2 =5.696,1 2.424,28.41 5;P <0.05).However,there were no significant differences in the positive expression rates of HIF-1 α,VEGF and COX-2 between ADH and DCIS tissue (χ2 =1 .699, 0.957,2.263;P>0.05).There was a correlation between over-expression of HIF-1 α,VEGF and COX-2 with the histological grade and lymph node metastasis of IDC repectively,wherease without correlation with age and size of tumor (χ2 =3.41 0,0.509,0.1 03;P >0.05 ).The expression of COX-2 was positively correlated with HIF-1 αand VEGF(r =0.263,χ2 =5.41 2,P<0.05;r =0.436,χ2 =9.441 ,P <0.05). Conclusions The overexpression of HIF-1 α,VEGF and COX-2 might be important biological markers for the invasion,lymph node metastasis and distant metastasis of IDC.The combined detection of HIF-1 α,VEGF and COX-2 is a predictor for prognosis.
