Quality of life in elderly patients with acute myeloid leukemia: patients may be more accurate than physicians.

Background: The aim of this study was to evaluate changes in quality of life scores and their association with therapy and survival in unselected elderly patients with acute myeloid leukemia.

Design And Methods: From February 2003 to February 2007, 113 patients aged more than 60 years with de novo acute myeloid leukemia were enrolled in a prospective observational study. Two different quality of life instruments were employed: the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - C30 (EORTC QLQ-C30) and a health-related quality of life questionnaire for patients with hematologic diseases (QOL-E).

BCR-ABL nuclear entrapment kills human CML cells: ex vivo study on 35 patients with the combination of imatinib mesylate and leptomycin B.

The BCR-ABL oncoprotein of chronic myelogenous leukemia (CML) localizes to the cell cytoplasm, where it activates proliferative and antiapoptotic signaling pathways. We previously reported that the combination of the ABL kinase inhibitor imatinib mesylate (IM) and the nuclear export inhibitor leptomycin B (LMB) traps BCR-ABL inside the nucleus, triggering the death of the leukemic cells. To evaluate the efficacy of the combination of IM and LMB on human cells we collected CD34-positive cells from 6 healthy donors and myeloid progenitors from 35 patients with CML.

Survivin expression in chronic myeloid leukemia.

In this study, we investigated the expression of survivin (SVV) in 44 patients with typical Ph-positive chronic myeloid leukemia (CML) in different phases of the disease as well as in 20 matched healthy donors. We found a very high SVV expression in a predominant percentage of CML patients. We also observed a significantly increased SVV expression in patients in accelerated/blastic phase of the disease compared to patients in chronic phase.

Familial B-cell chronic lymphocytic leukemia in a population of patients from Southern Italy.

We investigated the prevalence of chronic lymphocytic leukemia (CLL) in 9650 relatives of 510 CLL patients from 5 different regions (Apulia, Basilicata, Campania, Calabria, and Sicily) of Southern Italy. Data collection included a family history questionnaire. In our series of 510 CLL patients, 53 families with 2 or more individuals who had chronic lymphoproliferative disease (CLD) or other hematological malignancies were identified.

T cell receptor delta-chain gene rearrangement in a novel case of adult NK cell leukemia.

Malignancies arising from natural killer (NK) cells are being increasingly recognized as distinct clinicopathological entities. We here report the characteristics of a peculiar case of NK-cell acute leukemia with unusual agranular morphology and rearrangement of the T-cell receptor (TCR) delta-chain gene.

Flow cytometric detection of aneuploid CD38(++) plasmacells and CD19(+) B-lymphocytes in bone marrow, peripheral blood and PBSC harvest in multiple myeloma patients.

DNA aneuploidy has been used as a genetic marker of malignancy in multiple myeloma (MM). CD38 and CD138 expression and absence of CD22 and CD19 may define plasmacells (PC). Several authors support evidences of circulating plasmacells, and their role in relapse after autologous stem cell transplantation has been hypothesised.

Multidrug resistance mechanisms in chronic lymphocytic leukaemia.

We evaluated the presence of P-glycoprotein (P-gp)-170, multidrug resistance protein (MRP), lung resistance protein (LRP)-56 and Bcl-2 in CD19-positive cells from 100 cases of chronic lymphocytic leukaemia (CLL). P-gp-170 was found in 73% of the CLL cases with no significant difference regarding stage or previous treatment. LRP-56 protein was homogeneously distributed with no differences for stage or treatment.
