Abstract

FOXP3-expressing regulatory T-cells (Tregs), which suppress aberrant immune response against self-antigens, also suppress anti-tumor immune response. It has been shown that there is an increased proportion of Tregs in several different human malignancies, although the actual mechanism remains unclear. The research aims to explore the relationship between the number of Tregs and a predict prognosis in particular hematological diseases as monoclonal gammopathies of uncertain significance (MGUS). Tregs were evaluated by means of flow cytometry (CD4+CD25(high/+) CD127(low/-)) in whole peripheral blood of 56 patients with MGUS to predict progression to overt multiple myeloma (MM). In two groups of patients, MGUS versus MGUS evolved to MM, we found a significative difference for the number of white blood cells, but not in terms of clinical and laboratory features evaluated at diagnosis. The study demonstrated the absence of a prognostic relevance of Tregs in MGUS. Nevertheless, their role in these disorders is still to be defined.
