OBJECTIVE: To investigate the potential efficacy of panaxadiol saponins component (PDS-C), a biologically active fraction isolated from total ginsenosides, to reverse chemotherapy-induced myelosuppression and pancytopenia caused by cyclophamide (CTX). METHODS: Mice with myelosuppression induced by CTX were treated with PDS-C at a low- (20 mg/kg), moderate- (40 mg/kg), or high-dose (80 mg/kg) for 7 consecutive days. The level of peripheral white blood cell (WBC), neutrophil (NEU) and platelet (PLT) were measured, the histopathology and colony formation were observed, the protein kinase and transcription factors in hematopoietic cells were determined by immunohistochemical staining and Western blot...

We describe an 80-year-old woman who presented with headaches, bilateral jaw claudication and visual symptoms. She was diagnosed with giant cell arteritis, which was confirmed by temporal artery biopsy. She was treated with high-dose prednisone followed by a slow taper, with complete resolution of symptoms. Approximately 4 years later, she developed progressively worsening renal function associated with haematuria. Serological workup revealed a high-titre perinuclear antinuclear cytoplasmic antibody and antibodies to myeloperoxidase...

The impact of pharmacogenetics on predicting survival in diffuse large B-cell lymphoma (DLBCL) remains unclear. We tested 337 DLBCL patients treated with rituximab-cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) for 9 single nucleotide polymorphisms from 6 genes (CD20, FCGR2A, NAD(P)H, ABCC2, ABCG2 and CYP3A5). Patients who carried the NCF4 rs1883112 GG genotype showed significantly shorter progression-free survival (PFS) (P = 0.023) and event-free survival (EFS) (P < 0.001) comparing with A allele...

The absolute peripheral blood lymphocyte count at diagnosis is known to be a strong prognostic factor in patients with diffuse large B-cell lymphoma (DLBCL) treated with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP), but it remains unclear as to which peripheral blood lymphocyte population is reflective of DLBCL prognosis. In this cohort, 355 patients with DLBCL treated with R-CHOP from 2006 to 2013 were analyzed. The low absolute CD4+ T-cell count (ACD4C) at diagnosis negatively correlated with the overall response rate and the complete response rate significantly (P<0...

Hepatitis B reactivation can occur with various forms of immunosuppression. Cyclophosphamide, Bortezomib, and Dexamethasone (CYBOR-D) chemotherapy is commonly used for the treatment of multiple myeloma and has not been noted in guidelines to be causative in HBV reactivation. Indeed, current guidelines do not recommend providing antiviral prophylaxis to patients with prior HBV infection. We present a case of HBV reactivation as a result of CYBOR-D and autologous stem cell transplant which is complicated by the patient's partner who developed acute hepatitis B...

BACKGROUND AND AIMS: Malignant melanoma is an aggressive tumor sensitive for immunotherapy such as checkpoint blockade antibodies. Still, most patients with late stage disease do not respond, and the side effects can be severe. Stimulation of the CD40 pathway to initiate anti-tumor immunity is a promising alternative. Herein, we demonstrate immune profiling data from melanoma patients treated with an adenovirus-based CD40 ligand gene therapy (AdCD40L). METHODS: Peripheral blood mononuclear cells and plasma were collected from malignant melanoma patients (n = 15) enrolled in a phase I/IIa study investigating intratumoral delivery of AdCD40L with or without low dose cyclophosphamide...

A 71-year-old man was diagnosed with T-Large granular lymphocytic (LGL) leukemia, which usually represents a relatively indolent clinical course. While the clinical manifestation of this patient we report herein was aggressive with lasting fever, splenomegaly and hemophagocytic lymphohistiocytosis (HLH). T-cell immunophenotype was CD3+CD4-CD8-CD5-CD7-TCRαβ+. After comprehensive evaluation, an adjusted chemotherapy regimen CEOP (cyclophosphamide, vincristine, etoposide, prednisone) with etoposide, a potential effective regimen for HLH was administrated to the patient...

Following a multivariant analysis we demonstrated that children and adolescents with Burkitt lymphoma (BL) and a 13q14.3 deletion have a significant decrease in event free survival (EFS) despite identical short intensive multi-agent chemotherapy. However, how this deletion in the 13q14.3 region is associated with a significant decrease in EFS in children and adolescents with BL is largely unknown. The gene Deleted in Lymphocytic Leukemia 1 (DLEU1) is located in the region of 13q14.3. Here, we report that DLEU1 expression is implicated in the regulation of BL programmed cell death, cell proliferation, and expression of apoptotic genes in transcription activator-like effector nuclease (TALEN)s-induced DLEU1 knockdown and DLEU1 overexpressing BL cell lines...

Purpose The standard treatment of patients with diffuse large B-cell lymphoma (DLBCL) is rituximab in combination with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). Lenalidomide, an immunomodulatory agent, has shown activity in DLBCL. This randomized phase III trial compared lenalidomide as maintenance therapy with placebo in elderly patients with DLBCL who achieved a complete response (CR) or partial response (PR) to R-CHOP induction. Methods Patients with previously untreated DLBCL or other aggressive B-cell lymphoma were 60 to 80 years old, had CR or PR after six or eight cycles of R-CHOP, and were randomly assigned to lenalidomide maintenance 25 mg/d or placebo for 21 days of every 28-day cycle for 24 months...

Gastric leiomyosarcoma is a recalcitrant cancer and chemotherapy strategy is controversial. The present study used a patient-derived orthotopic xenograft (PDOX) nude mouse model of gastric leiomyosarcoma to identify an effective therapeutic regimen in order to develop individualized precision medicine for this disease. A gastric leiomyosarcoma obtained from a patient was first grown in transgenic nude mice ubiquitously expressing red fluorescent protein (RFP) in order to stably label the tumor stroma. The RFP-expressing tumor was then passaged orthotopically in the gastric wall of non-transgenic nude mice to establish an imageable PDOX (iPDOX) model...

Malignant and cardiovascular disorders are the top causes of mortality worldwide. This article reviews the main literature data and mechanisms linking hematologic malignancies and arterial stiffness, focusing on recent experimental and clinical results. Several links were found in hematologic malignancies between complete blood count and arterial stiffness. Chemotherapy, especially anthracyclines, cyclophosphamide and tyrosine kinase inhibitors, as well as radiotherapy and hematopoietic stem cell transplantation are the main known causes of arterial stiffness increase in hematologic malignancies...

Diffuse large B-cell lymphomas (DLBCLs) are clinically heterogeneous and need a biomarker that can predict the outcome of treatments accurately. To assess the prognostic significance of the cell-of-origin type for DLBCLs, we applied the Lymph2Cx assay using a NanoString gene expression platform on formalin-fixed paraffin wax-embedded pretreatment tissues obtained from 82 patients with de novo DLBCL, not otherwise specified. All patients were treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) as the first line of chemotherapy...

Central nervous system (CNS) vasculitis (CNS) in systemic erythematosus lupus (SLE) is a rare and challenging diagnosis. We report four cases of CNS vasculitis that occurred 5 to 16 years after the diagnosis of SLE. Magnetic resonance imaging (MRI) detected different features suggestive of CNS vasculitis: enhancement and thickening of the vascular wall, vascular stenosis, ischemic brain lesions and intracerebral haemorrhage unlikely to correspond to other mimic aetiologies. Three patients received combination therapy with glucocorticoids (GC) and cyclophosphamide (CYC)...
