Hormone Receptor Positive/HER2 Negative Breast Carcinoma: Association of PIK3CA Mutational Status with PD-L1 and Tumor Cell Microenvironment and Their Prognostic Significance. (PubMed, Int J Mol Sci)
In patients with PIK3CA mutation and exon 20 PIK3CA mutation there was statistically significant longer survival without recurrence (p = 0.026 and p = 0.041, respectively). Research regarding PD-L1 expression, immune cells and PIK3CA mutations might have an impact on how to determine therapeutic approaches for patients with HR+/HER2- breast carcinoma.

The Clinicopathological and Prognostic Significance of the Expression of PD-L1 and MET Genes in Breast Cancer: Potential Therapeutic Targets. (PubMed, Curr Cancer Drug Targets)
The expression of the PD-L1 and MET genes is remarkably associated with worse tumor clinicopathologic features and poor prognosis in patients with breast cancer. Further investigations using combination drug regimens targeting PD-L1 and MET are important, particularly in breast tumors expressing high levels of both proteins.
