Summary

The goal of the study is to evaluate the impact of somatic PI3KCA mutations on pCR in HER2-positive early breast cancer in real life. The main question it aims to answer iS.

\- Is there a correlation between PIK3CA mutations and response to neoadjuvant chemotherapy in HER2 early breast cancer? Participants who received neoadjuvant chemotherapy in addition to anti-Her2 target therapy will undergo PIK3CA analysis in order to answer to this question.

PIK3CA analysis

PIK3CA will be investigated together with HER2 in pre-NAD tissue samples, in order to evaluate the correlation with response to NAD chemotherapy, with a 16-gene MYRIAPOD kit. This evaluation will be performed on all 58 patients in the study for group (responders and not responders). Moreover 10 patient samples (5 responders and 5 non-responders) will be subjected to gene expression profile analysis. Specifically, a transcriptomic analysis will be performed on total RNA from one inch of cells (10-50 cells isolated by LCM from FFPE biopsy, RNA seq) which will allow to have the transcriptional profile for each patient of protein-coding transcripts (coding RNAs) and long non-coding RNAs. In addition, an NGS analysis by TSO500 will be performed in parallel, on the slide following the previous one, to have the genome sequence (523 genes) on the same 10-50 cells isolated by LCM from FFPE biopsy for the identification of any mutations.
