Introduction: The presence of disseminated tumor cells (DTC) in bone marrow (BM) of breast cancer patients is associated with reduced clinical outcome. Bisphosphonate treatment was shown to eradicate DTC. This controlled study aimed to investigate the influence of zoledronic acid (ZOL) on DTC and survival of breast cancer patients. Methods: Patients with primary breast cancer and DTC-positive bone marrow were randomized to treatment with ZOL plus adjuvant systemic therapy (n = 40) or adjuvant systemic therapy alone (n = 46). DTC were identified by immunocytochemistry using the antibody A45B/B3. The change in DTC…
