Mucormycosis is a rare, opportunistic fungal infection that occurs almost exclusively in immunocompromised hosts such as patients with diabetes mellitus, leukemia, lymphoma, renal disease, septicemia, burns, malnutrition, and following long-term treatment with steroids and antibiotics. Based on the clinical presentation and involvement, mucormycosis is classified as six major forms, namely, rhinocerebral, pulmonary, cutaneous, gastrointestinal (GI), disseminated and miscellaneous, with rhinocerebral and pulmonary being the common forms...

The survival rate of children with cancer is now close to 80 %, as a result of continuous improvement in diagnostic and treatment procedures. Prevention and treatment of treatment-associated complications is now a major challenge. Thromboembolic venous disease, due to multifactorial pathogenesis, is a frequent complication (up to 40 % asymptomatic thrombosis in children with cancer), responsible for significant morbidity. Predominantly in children with acute lymphoblastic leukemia, lymphoma, or sarcoma, thromboembolic disease justifies primary prophylaxis in certain populations at risk, whether genetic or environmental...

Umbilical cord blood is a source of hematopoietic stem cells essential to treat life-threatening diseases, such as leukemia and lymphoma. However, only a very small percentage of parents donate upon delivery. The decision to donate the cord blood occurs at a very specific time and when parents likely experience emotional, informational, and decisional overloads; these features of cord blood donation make it different from other pro-social activities. In collaboration with an OB-GYN clinic in Milan, Italy, we conducted the first randomized controlled trial that applies tools from behavioral science to foster cord blood donation, and quantified the gains that informational and behavioral "nudges" can achieve...

Patients with mycosis fungoides (MF), the most common subtype of primary cutaneous T-cell lymphoma, have an increased risk of developing secondary malignancies. We herein report two rare cases of MF concurring with diffuse large B cell lymphoma (B lymphoid lineage) and acute myeloid leukemia (myeloid lineage) in two otherwise healthy elderly patients. Potential etiologic factors, including the impact of the therapy-associated inflammatory response on the development of secondary tumors in patients with MF, are discussed...

A collision tumor is defined as two histologically distinct tumor types identified at the same anatomic site. Hematolymphoid proliferative disorders (HLPDs), which coincide with non-hematological neoplasms, can mimic an immune response and can easily be overlooked as an immune reaction to a solid organ neoplasm, especially when low grade. In order to avoid a delay in the diagnosis of a HLPD during the workup for a non-hematological neoplasm, we identified a cohort of 100 cases with a HLPD diagnosis during the initial workup and treatment of a non-hematological neoplasm, or vice versa...

Feline leukemia virus (FeLV) was the first feline retrovirus discovered, and is associated with multiple fatal disease syndromes in cats, including lymphoma. The original research conducted on FeLV employed classical virological techniques. As methods have evolved to allow FeLV genetic characterization, investigators have continued to unravel the molecular pathology associated with this fascinating agent. In this review, we discuss how FeLV classification, transmission, and disease-inducing potential have been defined sequentially by viral interference assays, Sanger sequencing, PCR, and next-generation sequencing...

BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is a common and clinically relevant side effect of chemotherapy. Approximately 50% of all leukemia, lymphoma, colorectal- and breast cancer patients are affected. CIPN is induced by neurotoxic chemotherapeutic agents and can manifest with sensory and/or motor deficits. It is associated with significant disability and poor recovery. Common symptoms include pain, altered sensation, reduced or absent reflexes, muscle weakness, reduced balance control and insecure gait...

Diphtheria toxin (DT) related targeted toxins are effective in cancer treatment, but efficacy diminishes in time because of their immunogenic potential and/or former vaccinations. In order to overcome this limitation for DT2219, a promising bispecific targeted toxin which targets CD19 and CD22, we deimmunized the DT moiety, and thereby developed an exciting improved drug (dDT2219) which still has the potential to sufficiently target B-cell malignancies but also limits clearance because of its reduced immunogenicity...

Outcomes in very young CLL patients (age ≤40) are not well characterized. We compared 71 consecutive patients aged ≤40 with 142 "older" matched patients >40 from our institution and used SEER database as an independent comparison group. Patients in the two age groups were diagnosed at similar Rai stage. At diagnosis, very young patients had a similar rate of adverse cytogenetics, IGHV mutation and ZAP70 expression and had lower beta-2-microglobulin and a lower incidence of second malignancies. There was no difference between the groups with respect to incidence of autoimmune manifestations, family history of lymphoma, time to initiation of CLL therapy, response to therapy, or Richter's transformation...

A boy with central nervous system relapse of Burkitt leukemia developed fever and neurological symptoms and cognitive impairment. He had received multi-drug chemotherapy including rituximab. Enterovirus (EV) was detected in cerebrospinal fluid by polymerase chain reaction, and magnetic resonance imaging findings were consistent with viral infection. The patient was treated with intravenous immunoglobulin and within 1 month cleared his EV. Rituximab can cause a profound B-cell deficiency predisposing patients to infections including EV encephalitis...

An exercise program (EP) during cancer treatment seems to be a valid strategy against physiological and quality-of-life impairments, but scientific evidence of benefits among pediatric patients is still limited. This review summarizes the literature focused on randomized controlled trials of EP offered to patients during leukemia and lymphoma treatment. Studies published up to June 2017 were selected from multiple databases and assessed by three independent reviewers for methodological validity. The review identified eight studies, but several types of bias have to be avoided to provide evidence-based recommendations accessible to patients, families, and professionals...

BACKGROUND: Ayub Ommaya proposed a surgical technique for subcutaneous reservoir and pump placement in 1963 to allow access to intraventricular cerebrospinal fluid (CSF). Currently, the most common indication for Ommaya reservoir insertion (ORI) in adults is for patients with hematologic or leptomeningeal disorders requiring repeated injection of chemotherapy into the CSF space. Historically, the intraventricular catheter has been inserted blindly based on anatomical landmarks. The purpose of this study was to examine short-term complication rates with ORI with image guidance (IG) and without image guidance (non-IG)...

Human CD19 antigen is a 95-kDa type I membrane glycoprotein in the immunoglobulin superfamily whose expression is limited to the various stages of B-cell development and differentiation and is maintained in the majority of B-cell malignancies, including leukemias and non-Hodgkin lymphomas of B-cell origin. Coupled with its differential and favourable expression profile, CD19 has rapid internalization kinetics and it is not shed into the circulation, making it an ideal target for the development of antibody-drug conjugates (ADCs) to treat B-cell malignancies...

BACKGROUND: p53 is a tumor suppressor protein involved in regulating a wide array of signaling pathways. The role of p53 in the cell is determined by the type of imposed oxidative stress, its intensity and duration. The last decade of research has unravelled a dual nature in the function of p53 in mediating the oxidative stress burden. However, this is dependent on the specific properties of the applied stress and thus requires further analysis. METHODS: A systematic review was performed following an electronic search of Pubmed, Google Scholar, and ScienceDirect databases...

AIMS: Adult T-cell leukemia/lymphoma (ATLL) is an aggressive malignancy with a poor prognosis. Human leukocyte antigen (HLA) and β2M serve as key molecules in tumor immunity, and their expression is frequently reduced in tumor cells. Programmed cell death (PD)-1/PD-ligand1 (PD-L1) interactions play a role in escape of tumor cells from T-cell immunity. Therefore, this study aimed to determine the clinicopathological relevance of HLA and β2M expressions in ATLL cells and PD-L1 expression in lymphoma or stromal cells and predict the overall survival of patients with ATLL...

Arsenic trioxide (As2O3) is a potent drug for the treatment of acute promyelocytic leukemia (APL) and has achieved remarkable remissions in patients. Unfortunately, clinical reports have shown that the treatment is associated with cardiotoxicity. Many efforts have been made to mitigate drug mediated cardiac damage using naturally occurring antioxidant compounds possessing free radical scavenging activity. The present investigation aims to explore protective role of L-Ascorbic acid (L-AA) and α-Tocopherol (α-TOC) from As2O3 induced oxidative stress in H9c2 cardiomyocytes through the evaluation of Nrf2 (Nuclear factor erythroid 2-related factor 2) and Bcl-2 (B-cell lymphoma 2) transcription factors...
