摘要:
目的:探讨乳腺癌肿瘤蛋白在新辅助化疗(neoadjuvant chemotheapy,NAC)前后的变化。方法:对我院2012年至2013年间接受NAC(方案为:多西他赛+表柔比星/吡柔比星+环磷酰胺)的112例乳腺癌患者的肿瘤蛋白表达情况进行分析,比较NAC前后肿瘤蛋白的具体变化情况。结果:肿瘤蛋白从阳性转为阴性变化率最高的是Ki-67(37.5%),雌激素受体(estrogen receptor,ER)和P53变化率最低,均为16.1%。而从阴性转为阳性变化率最高为P53(13.3%),最低是Ki-67(2.7%)。ER(P=0.043)、Ki-67(P<0.001)和人类表皮生长因子受体(human epidermal growth factor receptor-2,HER2,P=0.035)和乳腺癌亚型(P<0.001)的变化具有统计学意义。Ki-67平均表达率的变化有统计学意义(P<0.001)。年龄>50岁与Ki-67的阳转阴的变化相关,肥胖和淋巴结转移的患者容易出现HER2阳转阴的变化。结论:NAC能引起肿瘤蛋白的改变,年龄、体质指数(body mass index,BMI)、淋巴结转移和T分期等因素与肿瘤蛋白的变化具有一定的相关性。
Abstract:
Objective:To evaluate the changes of the oncoproteins of breast cancer treated with neoadjuvant chemotherapy(NAC)(Docetaxel+Epirubicin/Pirarubicin+Cyclophosphamide). Methods:From 2012 to 2013,112 patients treated with NAC were included in this retrospective study. Data were analyzed using chi-square and t-test. Results:The highest changing rate from positive to negative was Ki-67(37.5%),while the lowest rate was estrogen receptor(ER) and P53(both 16.1%) respectively. The highest changing rate from negative to positive was P53(16.1%),while the lowest rate was Ki-67(2.7%). Significant changes were observed in ER(P=0.043),Ki-67(P<0.001)、HER2(P=0.035),breast cancer subtype(P<0.001) and proliferative fraction of Ki-67(P<0.001). Conclusion:NAC could make oncoproteins change. General information,such as age,obesity,lymph node,etc has a relationship with the changes of on-coproteins.
