BACKGROUND: To investigate the correlation of TargetPrint with local and central immunohistochemistry/fluorescence in situ hybridization assessment of estrogen (ER), progesterone (PgR), and human epidermal growth factor receptor 2 (HER2) in the first 800 patients enrolled in the MINDACT trial. PATIENTS … Continued

Comparison of MammaPrint and TargetPrint results with clinical parameters in German patients with early stage breast cancer

Publication Name: International Journal of Molecular Medicine

The 70-gene expression profile MammaPrint is a powerful prognostic indicator for disease outcome in breast cancer patients with improved prediction of recurrence risk compared to currently used guidelines. The microarray-based test TargetPrint further provides reliable, quantitative assessment of mRNA expression … Continued

Microarray-Based Determination of Estrogen Receptor, Progesterone Receptor, and HER2 Receptor Status in Breast Cancer

Publication Name: Clinical Cancer Research

Author(s): Paul Roepman, Hugo M. Horlings, Oscar Krijgsman, Marleen Kok, Jolien M. Bueno-de-Mesquita, Richard Bender, Sabine C. Linn, Annuska M. Glas and Marc J. van de Vijver

Purpose: The level of estrogen receptor (ER), progesterone receptor (PR), and HER2 aids in the determination of prognosis and treatment of breast cancer. Immunohistochemistry is currently the predominant method for assessment, but differences in methods and interpretation can substantially affect … Continued

Microarray-based determination of ER, PR and HER2 receptor status: validation and comparison with IHC assessments

Publication Name: Poster, SABCS 2008

Author(s): Paul Roepman, Hugo Horlings, Oscar Krijgsman, Jolien Bueno-de-Mesquita, Richard Bender, Sabine Linn, Annuska Glas and Marc van de Vijver

In breast cancer patients the level of expression of estrogen receptor (ER), progesterone receptor (PR) and HER2 is predictive for prognosis and/or treatment response. However, differences in assessment methods and interpretation can substantially affect the accuracy and reproducibility of the … Continued
