NEODOXy: Targeting Breast Cancer Stem Cells With Doxycycline

Summary

Despite modern surgical and medical treatments, breast cancer can re-occur and lead 20% of patients to death. During the last 20 years, pre-clinical studies have shown that treatment failures may be due to the presence of a sub-type of cancer cells, the cancer stem cells, which are resistant to chemotherapy and radiotherapy. By chance, doxycycline, an old, inexpensive and safe molecule seems to target effectively these cancer stem cells. This study proposes to check for the clinical efficacy of doxycycline to target the cancer stem cells and improve the response to neoadjuvant chemotherapy in ER+/HER2- breast cancers.
