Meeting presentations supported tweaking the clinical interpretation of Genomic Health's Oncotype DX and bolstered Biotheranostics' Breast Cancer Index.
Studies presented at the AACR meeting demonstrated how the registry can be used to evaluate how cancer patients with rare tumor markers respond to treatments.
Based on the findings, MD Anderson is already using HER2 status to recommend patients for clinical trials instead of EGFR drugs and authors recommend others follow suit.
The researchers also reported that combining an ER-directed therapy with an irreversible HER2 kinase inhibitor could overcome resistance.
New data on Kadcyla and Tecentriq will help doctors further refine precision medicine options for breast cancer patients with unmet needs.
In the I-SPY 2 TRIAL, a subset of TNBC patients with elevated HER2 and EGFR phosphorylation responded to treatment with the HER2-inhibitor neratinib.
The updated guidelines confirm HER2 gene amplification assessed by ISH and protein overexpression assessed by IHC are primary predictors of responsiveness to HER2 therapy.
The analysis of HER2 and HER3 mutation carriers emphasizes how these studies can lead both to broadening and to narrowing of the patient populations for targeted drugs.
At the AACR annual meeting, researchers presented results from the Phase II SUMMIT trial investigating the pan-HER-targeted therapy neratinib.
