Abstract

A study of genome evolution in a metastatic breast cancer bearing an activating PIK3CA mutation, following treatment with the PI(3)Kα inhibitor BYL719, shows that all metastatic lesions, when compared to the pre-treatment tumour, had lost a copy of PTEN; parallel genetic evolution of separate sites with different PTEN genomic alterations had led to a convergent PTEN-null phenotype resistant to PI(3)Kα inhibition.
