Genomic Impact of Neoadjuvant Therapy on Breast Cancer: Incomplete Response is Associated with Altered Diagnostic Gene Signatures

July 6, 2016

PUBLICATION: Ann Surg Oncol (2016) 23: 3317. https://doi.org/10.1245/s10434-016-5329-6. AUTHORS: Peter Beitsch, Pat Whitworth, Paul Baron, James Pellicane, Tina Treece, Erin Yoder, Mark Gittleman, NBRST Investigators Group SUMMARY: This substudy showed that NAT significantly altered the genomic signature of the patient’s breast cancer compared with the patient’s pre-treatment genomic profile. These alterations occurred in a subtype-dependent manner, suggesting that…

Molecular Subtyping Predicts Pathologic Tumor Response in Early-Stage Breast Cancer Treated with Neoadjuvant Docetaxel Plus Capecitabine with or without Trastuzumab Chemotherapy

September 4, 2014

PUBLICATION: Med Oncol. (2014) 31: 163. https://doi.org/10.1007/s12032-014-0163-9. AUTHORS: Soley Bayraktar, Melanie Royce, Lisette Stork-Sloots, Femke de Snoo, Stefan Glück SUMMARY: The overall pCR plus npCR rate was 25 % (30/122). Stratified by BluePrint/MammaPrint, patients of HER2 type had the best response (59 %), while luminal A (7 %) and B (9 %) subtypes had the poorest. The pCR…

Molecular Subtyping of Early-Stage Breast Cancer Identifies a Group of Patients Who Do Not Benefit from Neoadjuvant Chemotherapy

June 12, 2013

PUBLICATION: Breast Cancer Res Treat. 2013 Jun;139(3):759-67. doi: 10.1007/s10549-013-2572-4. AUTHORS: Glück S., de Snoo F., Peeters J., Stork-Sloots L., Somlo G. ABSTRACT: 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…
