BACKGROUND: Peripheral T-cell lymphomas (PTCLs) are non-Hodgkin's lymphomas (NHLs) with considerable variation in incidence across the world. They show a wide variety of clinicopathological features and generally associated with poor clinical outcome. Lymphoma data from different geographic regions will definitely aid in routine clinical practice and research work. PTCLs are reported with a higher frequency in Asia as compared to Western countries. OBJECTIVE: The objective of this study was to analyze the frequency and distribution of PTCLs diagnosed in a tertiary care cancer center in Kerala...

Non-Hodgkin lymphoma is a heterogeneous group of lympho-proliferative disorders. We performed a meta-analysis to summarize the available evidence from case-control studies and cohort study on the inconsistent association between occupational sun exposure and the risk of non-Hodgkin lymphoma. We searched PubMed, ISI web of science, the Cochrane Library, EMBASE and reference lists for relevant articles. Study specific odds ratios or relative risk and 95% confidence intervals were pooled by using fixed-effects or random-effects models...

Cardiac hematological malignancies (CHMs) are rare entities and comprise lymphoma, leukemic infiltration, and extramedullary manifestation of multiple myeloma. The aim of this work is to summarize typical growth patterns, imaging features, and outcome parameters of CHM. Overall, 12 cases from 4 centers were reviewed retrospectively together with 604 cases from the literature. Cardiac hematological malignancies were mainly represented by B-cell lymphoma (70.0%). Other entities were rarer. Almost half of the patients showed involvement of multiple cardiac structures...

PEG-aspariginase is a backbone chemotherapy agent in pediatric acute lymphoblastic leukemia and in some non-Hodgkin lymphoma therapies. Nurses lack standardized guidelines for monitoring patients receiving PEG-asparaginase and for educating patients/families about hypersensitivity reaction risks. An electronic search of 6 databases using publication years 2000-2015 and multiple professional organizations and clinical resources was conducted. Evidence sources were reviewed for topic applicability. Each of the final 23 sources was appraised by 2 team members...

Genomic analysis has greatly influenced the diagnosis and clinical management of patients affected by diverse forms of hematologic malignancies. Here we review how genetic alterations define subclasses of patients with acute leukemias, myelodysplastic syndromes (MDS), myeloproliferative neoplasms (MPNs), non-Hodgkin lymphomas and classical Hodgkin lymphoma. These include new subtypes of acute myeloid leukemia defined by mutations in RUNX1 or BCR-ABL1 translocations as well as a constellation of somatic structural DNA alterations in acute lymphoblastic leukemia...

Recent advances in the understanding of molecular pathogenesis of lymphoma have enabled us to clearly define disease entity by means of a disease-specific gene mutation and to select candidates for novel targeted therapy. In this review three different clinically relevant topics related to the molecular pathogenesis of lymphoma were covered. In the 2016 revision of the World Health Organization classification of lymphoid malignancies, firstly, disease-specific mutations such as MYD88 L265P in Waldenström macroglobulinemia and BRAF V600E in hairy cell leukemia were incorporated into diagnostic tests, and secondly, the determination of cell-of-origin in diffuse large B-cell lymphoma (DLBCL) was strongly recommended in diagnosis...

KML001 (NaAsO2, sodium metaarsenite, KOMINOX), a kind of arsenic compound, that has shown promising efficacy in non-Hodgkin's lymphoma (NHL) both in vitro and in vivo. In our study, the antileukemic effect of KML001 on acute lymphoid leukemia (ALL) and its mechanism of action were investigated. The results showed that KML001 inhibited cell proliferation in two types of ALL cell lines, CCRF-CEM and Molt-4. Exposure of ALL cells to KML001 induced apoptosis in a time-dependent manner. KML001 caused cell cycle arrest at G2/M phase instead of G0/G1 phase shown in other leukemia cells...

PURPOSE OF REVIEW: This article reviews the spectrum of neurologic complications associated with lymphoma, leukemia, and paraproteinemic disorders. While leptomeningeal metastasis is the most common complication of lymphoma and leukemia and peripheral neuropathy is the most common complication of paraproteinemic disorders, clinicians need to be familiar with the diverse neurologic complications of these disorders. RECENT FINDINGS: Lymphomatous nervous system involvement can be difficult to diagnose, especially when it is the presenting symptom...

Lymphomas involving the mediastinum occur in a wide age range and represent heterogeneous histological subtypes with various clinical symptoms and complex radiological findings. However, studies that describe the clinical and radiological features of different subtypes among Chinese pediatric and adult patients are limited. We analyzed the clinical, radiological and pathological features of 31 pediatric lymphomas involving the mediastinum, and compared them to the features of 21 adult patients. Although several histological subtypes were identified in adults, pediatric patients presented with T-cell lymphoblastic lymphoma/T-cell acute lymphoblastic leukemia (T-LBL/T-ALL) and classical Hodgkin lymphomas (CHL) in 24 and 7 cases, respectively...

Venetoclax is a first-in-class orally available, B-cell lymphoma (BCL)-2 inhibitor indicated for the treatment of patients with relapsed/refractory chronic lymphocytic leukemia (CLL) harboring the 17p deletion. We used a novel approach for evaluating venetoclax pharmacokinetics using only sparse sampling in 155 patients enrolled in a phase 2, multicenter, open-label study in CLL patients with the 17p deletion. Patients received venetoclax doses within 30 min after the completion of breakfast or the first meal of the day, with no specific recommendations for the fat content in the meal...

Bendamustine hydrochloride (BDM) is approved in the United States to treat chronic lymphocytic leukemia and relapsed indolent B-cell non-Hodgkin lymphoma. The first formulation marketed in the United States (original BDM) was a lyophilized product requiring reconstitution prior to dilution to the final admixture. A liquid formulation of BDM was subsequently introduced that did not require reconstitution before dilution. Both formulations are administered as a 500 mL admixture with a recommended infusion time of 30 or 60 minutes for chronic lymphocytic leukemia and indolent B-cell non-Hodgkin lymphoma, respectively...

BACKGROUND: The effects of pediatric solid organ transplantation on cancer risk may differ from those observed in adult recipients. We described cancers in pediatric recipients and compared incidence to the general population. METHODS: The US transplant registry was linked to 16 cancer registries to identify cancer diagnoses among recipients <18 years old at transplant. Standardized incidence ratios (SIRs) were estimated by dividing observed cancer counts among recipients by expected counts based on the general population rates...

Non-Hodgkin lymphoma (NHL) and leukemia are among the most common cancers worldwide. While the treatment of NHL/leukemia of B-cell origin has much progressed with the introduction of targeted therapies, few treatment standards have been established for T-NHL/leukemia. As presentation in both B- and T-NHL/leukemia patients is often aggressive and as prognosis for relapsed disease is especially dismal, this cancer entity poses major challenges and requires innovative therapeutic approaches. In clinical trials, oncolytic viruses (OVs) have been used against refractory multiple myeloma (MM)...

The established treatment algorithms for chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) are currently challenged by novel classes of drugs, with ibrutinib being one of the most effective. Published data suggest that patients with early progression under ibrutinib often emerge as having Richter's transformation (RT) with a rapidly fatal prognosis, mostly developing diffuse large B-cell lymphoma (DLBCL). In this respect, it is known that RT to large DLBCL occurs in about 5% of patients with CLL during the disease course and less frequently to Hodgkin lymphoma (HL)...

Management of patients with relapsed or refractory non-Hodgkin lymphoma (NHL) remains challenging, and novel effective agents are eagerly awaited. Blinatumomab is a bispecific T-cell engager, targeting CD19. While blinatumomab's primary clinical use has been in B-cell acute lymphoblastic leukemia (B-ALL), there are increasing data for its use in B-lineage lymphomas. Areas covered: The aim of this review is to highlight the clinical data for blinatumomab use in NHL. Herein, the authors provide an overview of blinatumomab, its mechanism of action, its proven efficacy against B-ALL, and its phase I-II data assessing its use in NHL Expert opinion: Blinatumomab has modest activity in phase I-II trials in NHL, and may represent a means of bridging patients with relapsed disease to hematopoietic stem cell transplant...

BACKGROUND: Agricultural workers may be exposed to potential carcinogens including pesticides, sensitizing agents and solar radiation. Previous studies indicate increased risks of hematopoietic cancers and decreased risks at other sites, possibly due to differences in lifestyle or risk behaviours. We present findings from CanCHEC (Canadian Census Health and Environment Cohort), the largest national population-based cohort of agricultural workers. METHODS: Statistics Canada created the cohort using deterministic and probabilistic linkage of the 1991 Canadian Long Form Census to National Cancer Registry records for 1992-2010...

CD30 is a member of the tumor necrosis factor receptor superfamily, member 8 (TNFRSF8), and its normal expression is restricted to activated T and B cells. In tumor cells, CD30 expression is most commonly associated with lymphoid malignancies (Hodgkin and non-Hodgkin lymphomas) and is a therapeutic target using anti-CD30 antibody. CD30 expression has been reported also in mostly adult non-lymphoid malignancies, raising the possibility of CD30-targeted therapy for additional tumors. In this study, we examined the incidence of CD30 expression in 251 hematopoietic and 334 non-hematopoietic cases of pediatric tumors...

The hepatitis B virus (HBV) is a major global issue, because an increased risk of hepatocellular carcinoma among patients infected with HBV is well established. Recently, it has been suggested that HBV is associated with other human cancers. However, the association between HBV and the risk of onset of hematological malignancies remains controversial. The aim of this large-scale retrospective cohort study was to evaluate the association between HBV infection and hematological malignancies. A retrospective analysis of 86,115 newly admitted patients at Shanghai Ruijin Hospital was performed...

Tyler A Herek, Christine E Cutucache
The role of the tumor microenvironment in leukemias and lymphomas is well established, yet the intricacies of how the malignant cells regulate and influence their non-malignant counterparts remain elusive. For example, chronic lymphocytic leukemia (CLL) is an expansion of malignant CD5(+)CD19(+) B cells, yet the non-malignant T cells play just as large of a role in disease presentation and etiology. Herein, we review the dynamic tumor cell to lymphoid repertoire interactions found in two non-Hodgkin's lymphoma subtypes: CLL and angioimmunoblastic T-cell lymphoma...
