Multiple myeloma (MM) patients have a highly variable disease course and survival varies from a few months to more than 10 years. Numerous prognostic factors have been identified, including age, performance status (PS), serum albumin, beta2-microglobulin (beta2M), lactate dehydrogenase (LDH), renal function, genetic factors, and serum free light chains(More)
International Staging System (ISS), serum free light chain ratio (sFLCR) and lactate dehydrogenase (LDH) are well known, easily assessed independent prognostic indicators of outcome in multiple myeloma (MM). The purpose of the study was to re-examine the prognostic contribution of these variables in a multicenter setting with special attention to MM(More)
Waldenstrom's macroglobulinemia (WM) is an indolent B-cell lymphoma of the lymphoplasmacytic type accompanied by a serum IgM component. However, conventional IgM quantification lacks sensitivity, does not precisely reflect tumor burden of WM, and, although being the main marker for monitoring response to treatment, may not be accurate. New serum M-component(More)
The distinction between WM and SMZL may be difficult since both entities share overlapping clinical, immunophenotypic, and histopathologic characteristics. In this context we evaluated whether CD138 expression could be added in the armamentarium of tools used to differentiate these entities. Sixty-nine patients were studied, 47 WM and 22 SMZL.(More)
BLyS is involved in CLL biology and its low soluble serum levels related to a shorter time to first treatment (TFT). TACI is a BLyS receptor and can be shed from cells' surface and circulate in soluble form (sTACI). We investigated the impact of serum BLyS and sTACI levels at diagnosis in CLL patients and their relationship with disease parameters and(More)
Background. Serum free light chains (sFLC), the most commonly detected paraprotein in CLL, were recently proposed as useful tools for the prognostication of CLL patients. Objective. To investigate the prognostic implication of sFLC and the summated FLC-kappa plus FLC-lambda in a CLL patients' series. Patients and Methods. We studied 143 CLL patients of(More)
Dear Editor, A 60-year-old Caucasian male was admitted to our hematology clinic on December 2007 due to persistent leukocytosis, fatigue, and lower back pain. Clinical examination showed tenderness in the lower back and femoral region as well as organomegaly. The complete blood count (CBC) revealed leucocytosis (18×10/L) with marked eosinophilia (8×10/L).(More)
