In order to investigate whether CCL20 is one of the commonly taxane-induced cytokines, more serum samples were collected from breast cancer patients in clinic before, during, or after chemotherapy in the presence of taxol or docetaxel in the neoadjuvant setting, and an enzyme-linked immunosorbent assay (ELISA) was conducted to measure CCL20 levels in sera. Here, CCL20 is linked to breast carcinoma.
