摘要

目的探讨经动脉灌注化疗对乳腺癌雌激素(estrogen receptor

ER)和孕激素受体(progesterone receptor

PR)表达的影响。方法应用逆转录聚合酶链式反应(RT-PCR)和免疫组化方法检测81例乳腺癌患者经动脉灌注化疗前后的雌孕激素受体表达情况。采用Western blot检测经动脉灌注化疗前后ER和PR的变化。结果 RT-PCR结果表明，81例患者中43例(53.1%)ER mRNA 水平升高，33例(40.7%)PR mRNA 水平升高，25例(30.9%) ER 和PR mRNA 水平同时升高。免疫组织化学结果提示，35例(43.2%) ER表达水平升高，其中14例（17.3%）由阴性转为阳性；21例（26.0%）PR表达水平升高，其中10例（12.2%）由阴性转为阳性;16例（19.8%）ER和PR表达同时升高。Western blot显示，经动脉灌注化疗后，81例患者中38例(46.9%)ER 蛋白水平升高，30例(37.0%)PR蛋白水平升高，21例(25.9%)ER和PR蛋白水平同时升高。结论经动脉灌注化疗可有效上调ER、PR mRNA和蛋白水平的表达，有利于后续化疗药物对肿瘤细胞的杀灭。

Abstract

Objective To investigate the effect of transarterial infusion (TAI) chemotherapy on estrogen receptor (ER) and progesterone receptors (PR) expression in breast carcinoma tissue. Methods Samples of 81 patients with breast carcinoma were selected in this study. ER and PR mRNAs levels in the samples were determined by RT-PCR. Immunohistochemistry was employed to measure ER and PR expressions in different samples before and after TAI chemotherapy. Western blotting was used to assay ER and PR proteins level in the samples before and after the chemotherapy. Results RT-PCR results indicated that ER mRNA level was increased in 43 cases (53.1%) and PR level in 33 cases (40.7%). Meanwhile

both ER and PR mRNAs levels were increased in 25 cases (30.9%). Immunohistochemistry results showed that ER level was up-regulated in 35cases (43.2%)

and PR level in 21 cases (26.0%). Both ER level and PR level were up-regulated in 16 out of 81 cases(19.8%). Western blotting also suggested that the both proteins levels of ER and PR were up-regulated in some patients after the chemotherapy. Conclusion Transarterial infusion neoadjuvant chemotherapy affects the mRNA and protein level of the hormone receptors

which facilitates the subsequent killing effect of chemotherapy on tumor cells. ER and PR expressions should be determined after the transarterial infusion chemotherapy

which might provide a guide for the subsequent treatment and prognosis.
