Dissecting the Pathways of Therapy Resistance in Early Breast Cancer

Within the 1st step MINDACT patients who have already relapsed will be asked to participate. For these patients a biopsy of the metastasis should have been taken. A molecular analysis of the stored primary tumor sample and of the metastatic sample, using new technologies, will be performed, and the characteristics of both samples will be compared. Within the 2nd step a prospective collection of the metastasis samples will be implemented and analysis of biological material from relapsing MINDACT patients is foreseen. This process will provide insights on the biology of breast cancer and allow us to better understand mechanisms of resistance to therapies, contributing to overcoming this important problem.
