RATIONALE: Placement of an indwelling pleural catheter is an established modality for symptom relief and pleurodesis in the treatment of malignant pleural effusion. Concerns remain regarding possible infectious complications, risk of hemorrhage, and the rate of pleurodesis with the use of pleural catheters in the treatment of hematologic malignancies. OBJECTIVES: The goals of our study were: (1) to evaluate the safety and cumulative incidence of pleurodesis with indwelling pleural catheters for patients with hematologic malignancies; and (2) to evaluate overall survival of this cohort of patients with pleural effusions...

BACKGROUND: Multiple myeloma is the second most prevalent hematologic malignancy and thought to be incurable. Therefore, it's urgent to find new drugs for treatment. Some experiments have shown that curcumin might have great potential in treating multiple myeloma, while the mechanism is still unknown. EZH2 and SUZ12 are the core proteins in PRC2 and their expression are increased in various human cancers, including the poor prognostic multiple myeloma. Meanwhile, the regulation of miRNAs and EZH2 has been demonstrated in other cancer researches, like lung cancer, pancreatic cancer, leukemia and so on...

Posttransplant Lymphoproliferative Disorder (PTLD) is one of the most common malignancies complicating solid organ transplantation. In contrast, PTLD accounts for a minority of secondary cancers following allogeneic hematopoietic cell transplantation (HCT). Here we report on a 61-year-old woman who received an ABO-mismatched, HLA-matched unrelated donor hematopoietic cell transplantation from a presumably healthy donor for a diagnosis of acute myeloid leukemia (AML). Eighteen months following her transplant, she developed a monoclonal gammopathy...

MS4A4A is a member of the membrane-spanning, 4 domain family, subfamily A (MS4A) that includes CD20 (MS4A1), FcRβ (MS4A2) and Htm4 (MS4A3). Like the first three members of this family, transcription of MS4A4A appears to be limited to hematopoietic cells. To evaluate expression of the MS4A4A protein in hematopoietic cell lineages and subsets we generated monoclonal antibodies against extracellular epitopes for use in flow cytometry. In human peripheral blood we found that MS4A4A is expressed at the plasma membrane in monocytes but not in granulocytes or lymphocytes...

TP53 deletion or mutation is frequent in B-cell malignancies and is associated with a low response rate. We describe here the p53 landscape in B-cell malignancies, from B-Acute Lymphoblastic Leukemia to Plasma Cell Leukemia, by analyzing incidence of gain or loss of function of actors both upstream and within the p53 pathway, namely MYC, RAS, ARF, MDM2, ATM and TP53. Abnormalities are not equally distributed and their incidence is highly variable among malignancies. Deletion and mutation, usually associated, of ATM or TP53 are frequent in Diffuse Large B-Cell Lymphoma and Mantle Cell Lymphoma...

OBJECTIVES/BACKGROUND: CXCR4 is a receptor for stromal-derived factor-1 (SDF-1), a molecule that has a chemotactic activity for lymphocytes and is important in homing of hematopoietic stem cells to their adult marrow. We evaluated the CXCR4 (CD184) expression in the harvest cells and in the post-transplant bone marrow (BM) and its relation to engraftment, as determined by the consensus criteria and chimerism. METHODS: This is a prospective study which included 30 patients undergoing hematopoietic stem cell transplantation; 15 patients received autograft and 15 patients received allograft on dates between January 2012 and May 2014...

A broad spectrum of diseases are associated with IgM monoclonal gammopathy, including Waldenstrom macroglobulinemia (WM), various types of B cell non-Hodgkin's lymphoma (NHL), multiple myeloma (MM), primary amyloidosis (AL), and monoclonal gammopathy of undetermined significance (MGUS); these are called IgM monoclonal gammopathy related diseases (IgM-RD). We investigated MYD88 L265P and WHIM-like CXCR4 mutations in various IgM-RD. Patients with serum immunofixation electrophoresis confirmed IgM monoclonal gammopathy who had enough material for DNA extraction and presented between January 2008 and October 2016 at Peking Union Medical College Hospital were enrolled in this cohort...

We studied 140 families with two or more lymphoid cancers, including non-Hodgkin lymphoma (NHL), Hodgkin lymphoma (HL), chronic lymphocytic leukemia (CLL), and multiple myeloma (MM), for deviation from the population age of onset and lymphoid cancer co-occurrence patterns. Median familial NHL, HL, CLL and MM ages of onset are substantially earlier than comparable population data. NHL, HL and CLL (but not MM) also show earlier age of onset in later generations, known as anticipation. The co-occurrence of lymphoid cancers is significantly different from that expected based on population frequencies (p < ...

Renal impairment (RI) is one of the hallmarks of multiple myeloma (MM) and carries a poor prognosis. Microvesicles (MVs) are membrane vesicles and play an important role in disease progression. Here, we investigated the role of MVs derived from MM cells (MM-MVs) in RI of MM. We found that MM-MVs significantly inhibited viability and induced apoptosis, but not epithelial-mesenchymal transition in human kidney-2 (HK-2), a human renal tubular epithelial cell line. The protein levels of cleaved caspase-3, 8, and 9, and E-cadherin, were increased, but vementin levels were decreased in the HK-2 cells treated with MM-MVs...

The Iraqi Bone Marrow Transplantation Center is located in the medical city complex of Bab Almuadham in Baghdad, Iraq. It was established on March 11, 2002, and performed its first mini-allotransplant for acute myeloid leukemia on January 24, 2003. Among 16 patients who received hematopoietic stem cell transplant between January 2003 and January 2010, one patient underwent allogeneic bone marrow transplant for acute myeloid leukemia and 15 patients received autologous bone marrow transplant for the following indications: 5 had multiple myeloma, 9 had lymphoma (8 with Hodgkin disease and 1 with non- Hodgkin lymphoma), and 1 had rhabdomyosarcoma...

Low cholesterol levels may be accompanied by solid tumors or hematological malignancies such as multiple myeloma. Decreased cholesterol levels have been reported in some experimental studies about chronic lymphocytic leukemia (CLL). It may be associated with tumoral cell metabolism. Herein, we examine blood lipid profiles of patients with newly diagnosed CLL (284 male, 276 female, mean age 64 ± 11 years) as defined by National Cancer Institute criteria. The control group consisted of 71 healthy subjects with mean age 55 ± 9 years (28 male, 43 females)...

SIGNIFICANCE: Several lines of evidence suggest that hematological malignancies exhibit an altered redox balance homeostasis that can lead to the activation of various survival pathways that, in turn, lead to the progression of disease and chemoresistance. Among these pathways, the heme oxygenase-1 (HO-1) pathway is likely to play a major role. HO is an enzyme that catalyzes regio-selective, oxidative degradation of heme with the simultaneous release of carbon monoxide (CO), ferrous iron (Fe2+), and biliverdin, which is reduced to bilirubin by biliverdin reductase...

Cancer treatments can have significant cardiovascular adverse effects that can cause cardiomyopathy and heart failure with reduced survival benefit and considerable decrease in the use of antineoplastic therapy. The purpose of this study is to assess the role of TLR2 and TLR4 gene expression as an early marker for the risk of doxorubicin-induced cardiomyopathy in correlation with early diastolic dysfunction in patients treated with doxorubicin. Our study included 25 consecutive patients who received treatment with doxorubicin for hematological malignancies (leukemia, lymphomas or multiple myeloma), aged 18-65 years, with a survival probability>6 months and with left ventricular ejection fraction>50%...

The presence of circulating plasma cells in patients with multiple myeloma is considered a marker for highly proliferative disease. In the present study, the impact of circulating plasma cells assessed by cytology on survival of patients with multiple myeloma was analysed. Wright-Giemsa stained peripheral blood smears of 482 patients with newly diagnosed myeloma or plasma cell leukaemia were reviewed and patients were classified in four categories according to the percentage of circulating plasma cells: 0%, 1-4%, 5-20% and plasma cell leukemia with the following frequencies: 382 (79...

Concurrences of multiple myeloma with myeloproliferative diseases or secondary myeloid leukemoid reactions are rather rare. The paper describes 3 cases of multiple myeloma: the first case concurrent with neutrophilic leukocytosis; the second case with secondary erythropoetin-dependent erythrocytosis, and the third case with chronic myeloid leukemia. In such cases, an accurate diagnosis requires molecular testing, besides routine clinical and laboratory studies. The paper discusses therapeutic strategy in cases of a concurrence of 2 competing tumors of the blood system: to treat them simultaneously or the most aggressive tumor now, as well as a relationship between multiple myeloma and chronic myeloid leukemia, other myeloproliferative disorders, and secondary myeloid leukemoid reactions...

Toll-like receptor 9 (TLR9) is expressed in a variety of B-cell malignancies and works as a bridge between innate and adaptive immunity. CpG oligodeoxynucleotides (CpG ODNs), TLR9 agonists, are able to induce anticancer immune responses and exert direct effects against cancer cells, serving as cancer therapeutic agents. Therefore, TLR9 might be a potential therapeutic target for drug development. However, several new evidences have revealed that direct effects of TLR9 agonists on B-cell malignancies is controversial...

Pathomorphological study of trephinobiopsy specimens from 129 patients with lymphoproliferative and myeloproliferative diseases was carried out over the course of chemotherapy. Combinations of initial and manifest myelofibrosis (loose network of reticulin fibers and extensive network of reticulin and collagen fibers, respectively) predominated at the debut of chronic myeloid leukemia, chronic lymphoid leukemia, and multiple myeloma. Manifest myelofibrosis was detected in patients with chronic myeloid leukemia without hematological response (failure of normalization of hematological values) and in patients with progressing and relapsing multiple myeloma...
