Abstract
Peripheral blood lymphocyte (PBL) count may reflect the immune status of cancer patients. We retrospectively analyzed the predictive and prognostic impact of baseline and post-chemotherapy PBL counts in a homogeneous group of 103 breast cancer patients treated with neoadjuvant chemotherapy (anthracyclines and taxanes). In univariate analysis, baseline PBL under 1500 × 10(6)/L (p = 0.013; hazard ratio [HR]: 2.80, 95%CI 1.24-6.61), and PBL decrease >200 × 10(6)/L after the first cycle of chemotherapy (p = 0.047; HR: 2.82, 95%CI 1.01-7.86) were significantly related to disease free survival. In multivariate analysis, both baseline PBL count less than 1500 × 10(6)/L (p = 0.034; HR: 3.32, 95%CI 1.09-10.02) and PBL decrease >200 × 10(6)/L after first cycle (p = 0.032; HR: 3.25, 95%CI 1.10-9.56) showed independent prognostic value for worse disease free survival. No effect was observed for overall survival. Our data support the relevance of pre- and post-chemotherapy PBL for breast cancer recurrence after neoadjuvant chemotherapy.Entities:
