Gene expression profiling highlights biological differences in the prognostic groups
We next aimed to better characterize the gene expression features associated with the HER2-EveNT score by evaluating correlations with known signatures and performing comparisons between the prognostic groups. This in-depth characterization allowed us to identify the most relevant features captured by the score, including mostly processes associated to immune activation and suppression.First, we evaluated the correlation between the HER2-EveNT score as a continuous variable and hallmark biological processes
