摘 要:[目的] 探讨激素受体阴性乳腺癌Ki67表达与新辅助化疗疗效的关系。[方法] 收集2006年1月5日至2015年12月31日在兰州大学第二医院手术治疗的75例符合条件的HR阴性乳腺癌患者,根据免疫组化法检测的Ki67表达水平将其分为高表达组(>30%)、中表达组(14%~30%)、低表达组(<14%)。回顾性分析三组患者的临床病理特征,分析 Ki67不同表达水平与新辅助化疗疗效之间的关系。[结果] 4周期新辅助化疗后RR为85.3%(64/75),其中CR为29.3%(22/75),PR为56.0%(42/75),SD为14.7%(11/75),无PD病例。其中pCR仅占17.3%(13/75)。Ki67高表达组与绝经前状态、较大的肿瘤直径、高肿瘤分级、淋巴管浸润、淋巴结阳性、HR阴性以及HER2阳性相关(P<0.05)。新辅助化疗可显著性降低Ki67的阳性表达率(P<0.01)。Logistic回归显示Ki67是乳腺癌新辅助化疗效果的独立预测因素(P>0.05)。[结论] Ki67表达水平及其变化可预测HR阴性乳腺癌肿瘤新辅助化疗疗效。 |

Abstract:[Objective] To investigate the relationship between Ki67 and clinical and pathological response to neoadjuvant chemotherapy(NAC) in HR negative breast cancer patients. [Methods] Clinical data of 75 HR-negative breast cancer cases treated in department of General Surgery of Second Hospital of Lanzhou University from January 5,2006 to December 31,2015 was collected,and divided into three groups by the expression levels of Ki67:high group(>30%),intermedium group(14%~30%),low group(<14%). The clinical and pathological features of three groups respectively,and the relationship between different groups and NAC effects were analzed. [Results] After 4 cycles of NAC,RR was 85.3%(64/75),CR was 29.3%(22/75),PR 56.0%(42/75),SD 14.7%(11/75),no cases of PD. pCR only was 17.3%(13/75). Ki67 high expression group correlated with pre-menopausal state,larger tumor diameter,high tumor grade,lymphatic invasion,lymph node-positive,HR-negative and HER2-positive(P<0.05). Neoadjuvant chemotherapy could significantly reduce the level of positive expression of Ki67(P<0.01). Logistic regression showed that Ki67 was an independent predictor in HR negative breast cancer patients treated by neoadjuvant chemotherapy(P>0.05). [Conclusion] Ki67 expression and its changes after therapy may be used for pathological response in HR-negative breast cancer after NAC. |
