ERBB2 and gonorrhea: The prevalence of HER2-low expression (scores 1+ and 2+ without HER2 amplification) in ApoCa was 39% without significant differences between PAC and ALC (37% vs 43%, P ═ 0.14); however, the HER2-low phenotype was more prevalent in triple-negative PAC than in ALC (70% vs 43% P < 0.001) (Table 2 and Figure 1A and 1B).
