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 BC.
Methods: Patients diagnosed with HER2-negative BC ( = 999) at our institution between January 2011 and December 2015 formed our study population. Clinicopathological characteristics, association between estrogen receptor (ER) expression and HER2-low, and evolution of HER2 immunohistochemical (IHC) score were assessed.

In the title compound, C(15)H(14)Cl(2)F(3)NO, synthesized by the reaction of 3-[(E)-2-chloro-3,3,3-trifluoro-prop-1-en-yl]-2,2-dimethyl-cyclo-propane-carb-oxy-lic acid and 2-chloro-aniline, the aromatic ring makes a dihedral angle of 76.7 (3)° with the plane of the cyclo-propane ring. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains running along the b axis.
