We used plasma samples from 112 women classified into two groups: 70 women with breast cancer (BC) and submitted to neoadjuvant chemotherapy (3 cycles) and 42 healthy women used as controls. In the group of BC, blood samples were taken before each cycle of chemotherapy and Gal-3 levels was evaluated by ELISA sandwich. Flow cytometry was used to study T cells apoptosis and activation. Before treatment, median value of Gal-3 was 6.31 ng/ml (range 1.07 - 50.74) in BC and 0.84 ng/ml (range 0.00 - 4.82) in HC. Gal-3 levels were highest in plasmas from BC (p < 0.001). During the same period, proportions of apoptotic T lymphocytes were highest in BC compared to HC (p < 0.05). Similar results were observed about T cells activation. According to clinical symptoms, we observed, in the group of patients with a low or null response to chemotherapy, a positive correlation between gal-3 levels and tumor size (rho = 0.48; p = 0.010). In addition, we found a dynamic relationship between gal-3 levels, tumor size and T lymphocytes apoptosis rates during treatment depending to the cure efficiency. We suggest gal-3 plasma concentrations could be used as predictive biomarker for chemotherapy efficiency in breast cancer patients. %K Galectin-3 %K T Lymphocyte %K B Lymphocyte %K Breast Neoplasms %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=116053
