Objective This study aimed to comprehensively analyze and compare the clinicopathological features and prognosis of Chinese patients with human epidermal growth factor receptor 2(HER2)-low early breast cancer(BC)and HER2-IHC0 *** Patients diagnosed with HER2-negative BC(N=999)at our institution between January2011 and December 2015 formed our study *** characteristics,association between estrogen receptor(ER)expression and HER2-low,and evolution of HER2 immunohistochemical(IHC)score were ***-meier method and log-rank test were used to compare the long-term survival outcomes(5-year follow-up)between the HER2-IHC0 and HER2-low *** HER2-low BC group tended to demonstrate high expression of ER and more progesterone receptor(PgR)positivity than HER2-IHC0 BC group(P<0.001).The rate of HER2-low status increased with increasing ER expression levels(Mantel-Haenszelχ^(2)test,P<0.001,Pearson’s R=0.159,P<0.001).Survival analysis revealed a significantly longer overall survival(OS)in HER2-low BC group than in HER2-IHC0 group(P=0.007)in the whole cohort and the hormone receptor(HR)-negative *** were no significant differences between the two groups in terms of disease-free survival(DFS).The discordance rate of HER2 IHC scores between primary and metastatic sites was 36.84%.Conclusion HER2-low BC may not be regarded as a unique BC group in this population-based study due to similar clinicopathological features and prognostic roles.

持续创新是企业在动态竞争环境中维持长期竞争优势的关键,然而,日益频发的专利侵权诉讼对企业创新稳定性造成重大影响。既有文献主要研究专利侵权诉讼与企业创新的直接关系,缺乏对其影响机制的探索。基于此,本文引入动态竞争视角,整合注意力基础观和事件系统理论,以中国沪深两市2012至2016年间1302家A股制造业上市企业为研究对象,使用层次回归分析法深入探究发明专利侵权诉讼与被诉企业创新之间的逻辑关系。研究发现,发明专利侵权诉讼对被诉企业创新投入具有正向影响;高管团队创新注意力在发明专利侵权诉讼与被诉企业创新投入关系中起负向调节作用,同时随着专利诉讼的事件属性越突出——颠覆性越大、诉讼时机越关键、诉讼时长越持久,高管团队创新注意力对发明专利侵权诉讼与被诉企业创新投入关系间的负向调节作用将被削弱。研究从内部决策者视角与外部事件属性层面揭示竞争互动中专利侵权诉讼影响被诉企业创新的边界范围,超越既有文献对二者关系的直接验证,并为理解动态竞争中企业创新的决策及其规律性提供更加契合的理论框架和逻辑参考。
