[Study of bone marrow in patients with breast cancer to detect tumor cells and their complexes]

The article presents results of the research of bone marrow of patients with breast cancer (BC) for the presence of tumor cells and their complexes using cytological and immunological methods of diagnostics. The results were compared with the works of foreign scientists working in oncology and it correlates with them. Quite a large percentage of detection of tumor cells in bone marrow even under I-II and III stages of the disease and a clear relationship with the clinical course: local recurrence, bone and visceral metastasis indicate that these data can be used in complex examination of patients with BC and take into account when planning the tactics of the treatment and follow-up during systemic polychemotherapy and hormonal therapy.
