e22094 Background: The immune therapy of human cancer is a promising therapeutic approach. Myeloid-derived suppressor cells (MDSCs) have been confirmed as an indispensable component of immune system and associated with tumor induced immune suppression. Thus, MDSCs play an important role in immune therapy. Although a lot of research work has been done, currently there exists limited data about MDSCs status in cancer patients. The aim of this study was to determine whether MDSCs levels in peripheral blood were different in healthy volunteers, benign breast tumor patients and breast cancer patients, and to investigate the relation between MDSCs and several characteristics in breast cancer patients. Methods: Peripheral blood cells (PBC) were collected from 36 normal healthy volunteers, 52 patients with breast cancer and 62 patients with benign breast tumor. Peripheral blood samples of breast cancer patients were obtained before treatment. Circulating MDSCs (identified as Lin-/Lo HLA-DR-CD33+) were measured by flow cytometry. Statistical methods included two sample t tests and one way ANOVA. Results: The percentage of MDSCs was higher in breast cancer than benign breast tumor patients and healthy volunteers (2.017% vs 1.578% vs1.594%; p=0.0002), and the stage III/IV breast cancer patients had more MDSCs accumulation than those in stage I/II (2.92% vs 2.155%; P=0.0806). The levels of MDSCs in peripheral blood showed a significant correlation with HER-2/neu expression in breast cancer patients, but had no correlation with incidence age, ER status, PR status and P53 expression respectively. The percentage of MDSCs was lower in HER-2/neu over expression breast cancer patients than HER-2/neu negative patients (1.715% vs 2.882%, GP=0.0012). Conclusions: MDSCs seemed to have positive correlation with clinical stage and negative correlation with HER-2/neu expression in breast cancer patients . Further research will contribute to the better understanding of the connection between MDSCs and breast cancer, to develop better approaches to breast cancer therapy.

Rationally designed, individualized therapeutic strategies have long been a desired objective for breast cancer patients and clinicians as an estimated 178,480 new cases of invasive breast cancer will be diagnosed among women in the United States this year and over 40,000 women are expected to die from the disease. [1] The increasing appreciation of breast tumor cellular heterogeneity raises fundamental questions as to the relative contributions of cellular subsets to the biologic behavior of an individual patient’s tumor. [2] As such, it has become increasingly clear that in many cases, an individualized strategy for the treatment of breast cancer would be of great benefit, and that the ability to isolate relevant cellular subsets from the main tumor population is one of the critical limits to accomplishing this goal.

Background: During tumor progression, circulating monocytes and macrophages are actively recruited into tumors where they alter the tumor microenvironment to accelerate tumor progression. In response to multiple microenvironmental signals from the tumor and stromal cells, macrophages change their functional phenotypes. Based on their function, macrophages are commonly classified into both, classical M1 and alternative M2 macrophages. M2-like tumor-associated macrophages promote breast tumor growth and survival, and may migrate into the peripheral blood. However, the level of circulating M2/M1-like monocyte ratio in the peripheral blood of breast cancer patients has not been yet clarified. Aim: To compare peripheral blood M2/M1 monocyte ratio among breast cancer patients, benign breast tumor patients and healthy subjects. Also, to investigate the role of peripheral blood M2/M1 monocyte ratio as a circulating breast cancer tumor marker and to asses the validity of this marker in differentiation between benign and malignant breast tumors. Methods: Flow cytometry technique was used to determine the peripheral blood M2/M1 monocyte ratio in three groups of subjects, i.e. 45 patients with breast cancer, 40 patients with benign breast tumor, and 40 healthy subjects as a control group. The results of carbohydrate antigen15-3 (CA15-3) determination were analyzed comparatively. Results: The peripheral blood M2/M1 monocyte ratio in patients with breast cancer (0.27±0.1) was significantly higher (P<0.001) than that in healthy subjects (0.07±0.05) and than in benign tumor subjects (0.08±0.04). The area under the receiver operating characteristic (ROC) curve of peripheral blood M2/M1 monocyte ratio determination was significantly higher (P≤0.001) than that of CA15-3 levels. Conclusion: M2/M1-like monocyte ratio is of a high diagnostic value for breast cancer and is a promising differentiating marker between benign and breast cancer tumor groups.
