The Oncotype DX assay was developed in extensive laboratory and clinical studies and was validated in an independent clinical study with prospectively-defined endpoints. The results of the initial validation study of the Oncotype DX assay in stage I/II, node-negative, estrogen-receptor-positive breast cancer were published in The New England Journal of Medicine (December 30, 2004).
