Normal Circulating B Cells Are Markedly Reduced In Follicular Lymphoma And Diffuse Large B Cell Lymphoma At Diagnosis
BLOOD(2014)
摘要
Background. The role of normal lymphocytes in the development of malignancies is investigated with increasing interest, with particular focus on lymphoproliferative disorders. A few recent reports, including a large study from our group, have shown that the lymphocyte/monocyte ratio (LMR) is often altered in diffuse large B cell lymphoma (DLB-CL) and a reduced LMR at diagnosis is associated with a poor response to therapy and a marked reduction in the overall survival expectancy. Reduction of LMR is primarily due to decreased levels of circulating lymphocytes, although an increase of circulating monocytes may also concur in reducing the LMR value. The present study was undertaken to further characterize the lymphocyte subpopulations in DLB-CL and in the other germinal-center derived Follicular Lymphoma (FL). In particular, the aim was to investigate possible abnormalities of either B or T-lymphocytes that might be present in patients with DLB-CL or FL at disease onset.
