Official title
Prospective Study to Identify Molecular Mechanisms of Clinical Resistance to Chemotherapy in Triple Negative Breast Cancer Patients
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a multicenter translational study to understand therapeutic resistance in patients undergoing standard chemotherapy for triple negative breast cancer. In the neoadjuvant setting, biopsy tissue samples from primary tumor will be collected and banked before the start of chemotherapy and after the completion of the treatment (post-chemotherapy and at the time of surgery). In the metastatic setting, tissue samples from metastatic lesions will be collected and banked before the start of chemotherapy and at the time of tumor progression. Additionally, blood samples will be drawn before treatment initiation (baseline) and at different time points during treatment. All samples will be stored in the Biological Resource Repository.
