Comparison of PIK3CA Mutation Prevalence in Breast Cancer Across Predicted Ancestry Populations

Abstract: PURPOSE Understanding the differences in biomarker prevalence that may exist among diverse populations is invaluable to accurately forecast biomarker-driven clinical trial enrollment metrics and to advance inclusive research and health equity. This study evaluated the frequency and types of PIK3CA mutations ( PIK3CAmut) detected in predicted genetic ancestry subgroups across breast cancer (BC) subtypes. METHODS Analyses were conducted using real-world genomic data from adult patients with BC treated in an acad… Show more

“…Dysregulation of the PI3K/AKT/mTOR pathway is common in ER-dependent breast cancer, and activating mutations of PIK3CA , the catalytic subunit of class 1 PI3 Kinase, occur in 40% of these tumors 8 . The PI3K pathway enhances the proliferation, motility and invasiveness of these tumor cells and activation of the mTOR complex 1 (mTORC1) maintains high levels of eIF4E-dependent protein translation 9,10 1114 .…”
