High parental age at childbirth has repeatedly been linked to childhood malignancies, while few studies have focused on the offspring's risk of adult cancer. In this population-based case-control study, we identified 32,000 patients with lymphoid neoplasms, diagnosed at ages 0-79 years during the period 1987-2011, and 160,000 matched controls in Sweden. Using prospectively registered data on their first-degree relatives, we evaluated the impact of parental age on the risk of lymphoid neoplasms by subtype. Overall, each 5-year increment in maternal age was associated with a 3% increase in incidence of offspring lymphoid neoplasms (hazard ratio = 1...

Hematopoietic neoplasms are often driven by gain-of-function mutations of the JAK-STAT pathway together with mutations of chromatin remodeling and DNA damage control pathways. The interconnection between the JAK-STAT pathway, epigenetic regulation or DNA damage control is still poorly understood in cancer cell biology. Areas covered: Here, we focus on a broader description of mutational insights into myeloproliferative neoplasms and peripheral T-cell leukemia and lymphomas, since sequencing efforts have identified similar combinations of driver mutations in these diseases covering different lineages...

Gamma delta (γδ) T-cell antigen receptor (TCR) expression and its related T-cell differentiation are not commonly reported in T-cell acute lymphoblastic leukemia/lymphoma (T-ALL). Here we report two pediatric T-ALL cases and present their clinical features, histology, immunophenotypes, cytogenetics, and molecular diagnostic findings. The first patient is a two-year-old girl with leukocytosis, circulating lymphoblasts, and a cryptic insertion of a short-arm segment at 10p12 into the long-arm segment of 11q23 resulting in an MLL and AF10 fusion transcript, which may be the first reported in γδ T-ALL...

BACKGROUND: In Ethiopia, there were greater than 2000 adult and 200 pediatric cancer patients annually in 2010, but the estimated number of cancer patients were increasing. Oncologic rehabilitation treatment may result in improved physical and mental impairment. There is a paucity of information about rehabilitation service utilization among cancer patients in Ethiopia. Hence, the purpose of this study was to assess the rehabilitation service for cancer patient and associated factors at Black Lion hospital, Addis Ababa, Ethiopia...

Constitutive activation of the PI3K/AKT signaling pathway is found in ~50-70% of AML patients. The SH2-containing inositol 5-phosphatase 1 (SHIP1) is a negative regulator of PI3K/AKT signaling in hematopoietic cells. SHIP1 knockout mice develop a myeloproliferative syndrome and concomitant deletion of SHIP1 and the tumor suppressor PTEN leads to the development of lethal B-cell lymphomas. In the study presented here, we investigated the role of SHIP1 as a tumor suppressor in myeloid leukemia cells in an in vivo xenograft transplantation model...

Chronic infection is one of the major causes of cancer, and there are several mechanisms for infection-mediated oncogenesis. Some pathogens encode gene products that behave like oncogenic factors, hijacking cellular pathways to promote the survival and proliferation of infected cells in vivo. Some of these viral oncoproteins trigger a cellular damage defense response leading to senescence; however, other viral factors hinder this suppressive effect, suggesting that cooperation of those viral factors is important for malignant transformation...

Immune checkpoint inhibitors block the co-inhibitory receptors on T cells to activate their cytotoxic immune function and are rapidly being explored for the treatment of various advanced-stage malignancies. These novel drugs have already significantly increased survival rates. The first available immune checkpoint inhibitors were cytotoxic T lymphocyte antigen 4 (CTLA-4) inhibitors (such as ipilimumab), followed by programmed cell death protein 1 (PD-1) and programmed cell death protein ligand 1 (PD-L1) inhibitors (such as pembrolizumab and nivolumab)...

To obtain background data of NOD/Shi-scid IL-2Rγ(null) (NOG) mice, severely immunedeficient mice, a total of 120 animals were examined at 7, 26 and 52 weeks-old (20 mice/sex/group). The survival rate at 52 weeks-old was 95% (19/20) in both sexes. Clinically, circling behavior in one direction along the cage wall was observed in males after 8 weeks and females after 47 weeks-old, and hunchback position was found in males after 32 weeks-old. Hematologically, lymphocyte count markedly decreased at all ages, while white blood cell count increased in several mice at 52 weeks-old...

The majority of blood cancers occur in the elderly. This fact conspires with an aging population in many countries to make rigorous assessment for frailty increasingly important for hematologic oncologists. In this review, we first define frailty and its relevance for patients with hematologic malignancy. Next, we review current data regarding the impact of domains of frailty on outcomes for blood cancers including myelodysplastic syndromes (MDS), acute leukemia, non-Hodgkin lymphomas such as chronic lymphocytic leukemia (CLL), and multiple myeloma...

BACKGROUND: Chronic disseminated candidiasis (CDC) is a severe invasive fungal infection principally observed during neutrophil recovery in patients with acute leukemia treated with intensive chemotherapy. Its pathophysiology remains unclear. We describe the management of six children with symptomatic CDC who did not respond to antifungal therapy. METHODS: The databases of the hematology-oncology departments of two tertiary pediatric medical centers were searched for all patients diagnosed with CDC from 2003 to 2015 who responded to corticosteroids after failing antifungal therapy...

Objectives: Philadelphia chromosome-like (Ph-like) genetic alterations define a subset of B lymphoblastic leukemia/lymphoma (B-ALL), which represents a separate provisional entity in the World Health Organization 2016 updated classification. However, these alterations have not been described outside the context of B-ALL. Methods: Cytogenomic array and molecular analysis identified a Ph-like signature in a mixed-phenotype acute leukemia (MPAL), B/myeloid, confirmed using conventional immunophenotypic and cytochemical analysis...

Objectives: KLHL6 is a recently described BTB-Kelch protein with selective expression in lymphoid tissues and is most strongly expressed in germinal center B cells. Methods: Using gene expression profiling as well as immunohistochemistry with an anti-KLHL6 monoclonal antibody, we have characterized the expression of this molecule in normal and neoplastic tissues. Protein expression was evaluated in 1,058 hematopoietic neoplasms. Results: Consistent with its discovery as a germinal center marker, KLHL6 was positive mainly in B-cell neoplasms of germinal center derivation, including 95% of follicular lymphomas (106/112)...

The present study aimed to screen and study the roles of differentially expressed proteins in the human esophageal cancer cell line Eca‑109, in the presence and absence of gemcitabine (GEM). The 3‑(4,5)‑dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide (MTT) method was used to assay the vitality of the Eca‑109 cells following treatment with GEM (1‑16 µg/ml). The cell apoptosis was measured by using fluorescence activated cell sorting. The proteins in the treated Eca‑109 cells were extracted, validated, and assayed via two‑dimensional gel electrophoresis combined with matrix‑assisted laser desorption/ionization time of flight mass spectrometry (MALDI‑TOF‑MS)...

Serine-arginine protein kinase 1 (SRPK1) has been used as an important signal mediator, and is associated with cancer development. However, studies have yet to determine whether SRPK1 suppresses leukemia cell growth and induces apoptosis. Studies have also yet to reveal the underlying mechanisms. In the present study, the effects of downregulating SRPK1 gene expression on chronic myeloid leukemia cell lines (K562 cells) were investigated through RNA interference (RNAi) and the proliferation inhibition and apoptosis induction of SRPK1 in K562 cells were analyzed...

Background: Glyphosate is the most commonly used herbicide worldwide, with both residential and agricultural uses. In 2015, the International Agency for Research on Cancer classified glyphosate as "probably carcinogenic to humans," noting strong mechanistic evidence and positive associations for non-Hodgkin lymphoma (NHL) in some epidemiologic studies. A previous evaluation in the Agricultural Health Study (AHS) with follow-up through 2001 found no statistically significant associations with glyphosate use and cancer at any site...

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma. Histone deacetylase 6 (HDAC6) is frequently altered in DLBCL and inhibition of HDAC6 has potent anti-tumor effects in vitro and in vivo. We profiled miRNAs that altered in the HDAC6 knockdown DLBCL cells with NanoString nCounter assay and identified microRNA-27b (miR-27b) as the most significantly increased miRNA. We validated decreased expression of miR-27b in DLBCL tissues, and we found that low expression of miR-27b was associated with poor overall survival of patients with DLBCL...

Epidemiological studies have shown that inflammation plays a critical role in the development and progression of various chronic diseases, including cancers, neurological diseases, hepatic fibrosis, diabetic retinopathy, and vascular diseases. Decursin and decursinol angelate (DA) are pyranocoumarin compounds obtained from the roots of Angelica gigas. Several studies have described the anti-inflammatory effects of decursin and DA. Decursin and DA have shown potential anti-inflammatory activity by modulating growth factors such as vascular endothelial growth factor, transcription factors such as signal transducer and activator of transcription 3 and nuclear factor kappa-light-chain-enhancer of activated B cells, cellular enzymes including matrix metalloproteinases cyclooxygenase, and protein kinases such as extracellular receptor kinase, phosphatidylinositol-3-kinase, and protein kinase C...

HLA-DR is a member of the MHC class II antigen family expressed on hematological and solid tumors.  Antibodies directed against HLA-DR have demonstrated some clinical success, but toxicities limited development.  IMMU-140 is an anti-HLA-DR antibody-drug conjugate comprised of the active metabolite of irinotecan, SN-38, conjugated to a humanized anti-HLA-DR IgG4 antibody (IMMU-114); the IgG4 naked antibody is devoid of immune functions. Our aim was to determine if SN-38, the metabolite of a drug not commonly used in hematopoietic cancers, would be effective and safe when targeted to HLA-DR-expressing tumors...

BACKGROUND: The improving efficacy of cancer treatment has resulted in an increasing array of treatment-related symptoms and associated burdens imposed on individuals undergoing aggressive treatment of their disease. Often, clinical trials compare therapies that have different types, and severities, of adverse effects. Whether rated by clinicians or patients themselves, it can be difficult to know which side effect profile is more disruptive or bothersome to patients. A simple summary index of bother can help to adjudicate the variability in adverse effects across treatments being compared with each other...
