Publication Name: Annals of Surgical Oncology

Author(s): Whitworth P, Stork-Sloots L, de Snoo FA, Richards P, Rotkis M, Beatty J, Mislowsky A, Pellicane JV, Nguyen B, Lee L, Nash C, Gittleman M, Akbari S, Beitsch PD.

PURPOSE: The purpose of the NBRST study is to compare a multigene classifier to conventional immunohistochemistry (IHC)/fluorescence in situ hybridization (FISH) subtyping to predict chemosensitivity as defined by pathological complete response (pCR) or endocrine sensitivity as defined by partial response. … Continued

Estrogen receptor splice variants as a potential source of false-positive estrogen receptor status in breast cancer diagnostics

Publication Name: Breast Cancer Research and Treatment

Author(s): Groenendijk, Wilbert Zwart, Arno Floore, Stephanie Akbari, Rene Bernards

It is well established that only estrogen receptor (ER)-positive tumors benefit from hormonal therapies. We hypothesized that a subgroup of breast cancer patients expresses estrogen receptor a (ERa), but fails to respond to hormonal therapy due to the expression of … Continued

Molecular subtyping of early-stage breast cancer identifies a group of patients who do not benefit from neoadjuvant chemotherapy

Publication Name: Breast Cancer Research and Treatment

Author(s): Stefan Glück, Femke de Snoo, Justine Peeters, Lisette Stork-Sloots, George Somlo

The aim of this study was to analyze the correlation between the pathologic complete response (pCR) rate after neoadjuvant chemotherapy and long-term outcome (distant metastases-free survival [DMFS]) in patients with early-stage breast cancer using BluePrint and MammaPrint molecular subtyping versus … Continued

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

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

Use of a 70-Gene Signature to predict prognosis of patients with node-negative breast cancer: a prospective community-based feasibility study (RASTER).

Publication Name: Lancet Oncology

Background: A microarray-based 70-gene prognosis signature [MammaPrint] might improve the selection of patients with node-negative breast cancer for adjuvant systemic treatment. The main aims of this MicroarRAy PrognoSTics in Breast CancER (RASTER) study were to assess prospectively the feasibility of … Continued
