  Publication: St. Gallen Authors: Jennifer A. Crozier, Lisa Blumencranz, Miranda Kleijn, Heather Kling, Amy M. Truitt, Darina Proni, Christine Finn, William Audeh, Bastiaan van der Baan, FLEX Investigators’ Group Background: The personalized management of early-stage breast cancers is enhanced by the ability of genomic signatures to stratify tumors into Read More

5-year distant metastasis-free survival outcomes on the pre-operative use of MammaPrint and BluePrint for neoadjuvant decisions in the NBREaST II trial

Publication: St. Gallen Authors: E. Göker, M.P. Hendriks, M. van Tilburg, A. Barcaru, L. Mittempergher, A. van Egmond, M. Kleijn and D.
