The new analysis has confirmed earlier evidence that patients with high Oncotype DX risk scores appear to benefit significantly from added chemotherapy.
Authors concluded that all three assays — Oncotype DX, EndoPredict, and Prosigna — met Canadian thresholds for cost-effectiveness and urged caution in considering the findings.
Meeting presentations supported tweaking the clinical interpretation of Genomic Health's Oncotype DX and bolstered Biotheranostics' Breast Cancer Index.
The randomized data continue to distinguish Genomic Health's test for node-negative women, while new questions come to the fore node-positive disease and other areas of clinical care.
The researchers have used nCounter, an FDA-cleared platform from NanoString Technologies, to develop their gene expression assay for subtype classification.
