摘要

A 64-y-old man presented to Medical Oncology Department a metastatic invasive ductal breast carcinoma, positive for estrogen (ER) and progesterone receptors (PR) and Her2eu negative. The patient was treated with different lines of therapy, with rapid radiological progression of disease. After four courses of a third-line chemotherapy, a radiological stable disease was maintained. The patient was followed by serial blood drawings for the characterization and count of circulating tumor cells (CTC).
