BACKGROUND: A lack of access to methotrexate levels is common in low- and middle-income countries (LMIC), relevant for 80% of children with cancer worldwide. We evaluated whether high-dose methotrexate (HD-MTX) can be administered safely with extended hydration and leucovorin rescue, with monitoring of serum creatinine and urine pH. METHODS: The prospective study was conducted at a single centre in Chandigarh, India in 2015. Patients with B-cell acute lymphoblastic leukemia (ALL) or with T-cell ALL or non-Hodgkin lymphoma (T-NHL) were administered 3 and 5 gm/m2 of MTX (24 hr infusion), respectively...

PURPOSE: Primary pancreatic carcinoma and pancreatic metastases are rare in the pediatric population. Pancreatoblastoma is the most common pancreatic malignant tumor in young children and solid-pseudopapillary tumor in teenagers. Pancreatic adenocarcinoma is extremely rare under the age of 40 and is usually associated with underlying genetic abnormalities. Secondary malignancies of the pancreas occur more frequently than primary pancreatic malignancies in children and are most commonly seen with non-Hodgkin lymphomas (NHL) and mesenchymal sarcomas...

Non-Hodgkin lymphoma (NHL) is a heterogeneous group of lymphoid malignancies with high incidence in adolescents and young adults (AYAs). The most common diseases include diffuse large B-cell lymphoma, anaplastic large cell lymphoma, Burkitt lymphoma, lymphoblastic lymphoma, and primary mediastinal large B-cell lymphoma. In comparison to younger children and adults, AYAs (15-39 years) with NHL present a specific set of challenges including variations in tumor biology, inconsistent treatment, pharmacodynamics, and psychosocial barriers...

BACKGROUND: The Children's Oncology Group AHOD0431 study evaluated a response-directed treatment paradigm in which minimal initial chemotherapy and low-dose radiation was received only by patients who did not achieve a complete remission, and a chemotherapy/low-dose radiation salvage regimen was received by those who had a protocol-defined, low-risk recurrence. METHODS: Patients younger than 21 years who had stage IA or IIA nonbulky disease were eligible. The treatment strategy was evaluated by determining the proportion that received minimal chemotherapy alone, the proportion that had a first or second remission without the receipt of high-dose chemotherapy/stem cell rescue or higher dose involved-field radiation therapy (>21 grays), and overall survival...

PURPOSE: The purpose of this study is to determine the incidence of radiation pneumonitis (RP) in children receiving radiation therapy (RT) for Hodgkin lymphoma (HL). METHODS AND PATIENTS: A retrospective chart review was conducted of pediatric HL patients who received multiagent chemotherapy followed by RT to any part of the chest. The National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.03, was used to determine the RP grade. Parameters analyzed included sex; age; bleomycin dose; and RT dosimetric variables such as mean lung dose (MLD), mean individual (i; right vs left) lung dose or iMLD, V5 to V25, and individual lung V5 to V25...

PURPOSE: The presented protocol for pediatric intermediate-risk Hodgkin lymphoma evaluated the use of a dose-intensive chemotherapy regimen (ABVE-PC [doxorubicin, bleomycin, vincristine, etoposide, cyclophosphamide, prednisone]) with response-based therapy augmentation (addition of DECA [dexamethasone, etoposide, cisplatin, cytarabine]) or therapy reduction (elimination of radiation). METHODS AND MATERIALS: A central review of the radiation therapy data for quality assurance was performed, and the association between radiation protocol deviation (RPD) and relapse was assessed in the pediatric group (age <15 years) and adolescent and young adult (AYA) group (age ≥15-21 years)...

No systematic reviews are available on data from humans on cancer risk from exposure to permethrin, a widely used insecticide for which some animal studies have reported positive findings based on mechanisms that may not be relevant to humans. We identified potentially relevant articles through a search of electronic databases which included all studies of pesticide exposure and human cancer. A total of 18 articles were selected, including six identified from the list of references of other articles. Most articles were based on analyzes of the Agriculture Health Study (AHS); they provided no evidence of an increased risk of cancers of colon, rectum, pancreas, lung, melanoma, female breast, prostate, urinary bladder, as well as non-Hodgkin lymphoma (including its main subtypes), and leukemia...

BACKGROUND: Activating enhancer of zeste homolog 2 (EZH2) mutations or aberrations of the switch/sucrose non-fermentable (SWI/SNF) complex (eg, mutations or deletions of the subunits INI1 or SMARCA4) can lead to aberrant histone methylation, oncogenic transformation, and a proliferative dependency on EZH2 activity. In this first-in-human study, we aimed to investigate the safety, clinical activity, pharmacokinetics, and pharmacodynamics of tazemetostat, a first-in-class selective inhibitor of EZH2...

Hodgkin's Lymphoma (HL) reveals variable epidemiological and clinico-pathological features in different geographical locations. In this retrospective study, we aimed to assess the epidemiological and clinic-pathological features, and outcome of HL patients treated at one hemato-oncology centre in Erbil, northern Iraq. Medical records of 103 HL patients treated over more than six years were reviewed. Treatment outcome was evaluated by measuring the 5-year overall and progression-free survival rates. The median age of patients was 23 years, children up to 17 years constituted 31...

BACKGROUND: Lymphoma is the third most common malignancy in children (0-14 years) and the first in adolescents (15-19 years). This population-based study-the largest ever done in Spain-analyses incidence and survival of lymphomas among Spanish children and adolescents. PATIENTS AND METHODS: 1664 lymphoma cases (1983-2007) for incidence and 1030 for survival (1991-2005) followed until 31/12/2010, were provided by 11 cancer registries. Age-adjusted incidence rates (ASRw) to the world standard population were obtained; incidence trends were modelled using the Joinpoint programme, observed survival (OS) was estimated with Kaplan-Meier and trends tested with a log-rank test...

Data about malignant blood diseases are sparse in Cameroon. Their epidemiology was studied in patients at the General Hospital of Douala (GHD) and the Yaoundé Central Hospital (CHY) from 2004 through 2014. The variables we studied were social and demographic (age, sex, occupation, marital status), clinical (reasons for consultation, clinical signs, year of diagnosis), and biological (blood count, myelogram and blood smear, immunophenotyping, biopsy, and cytogenetics). In all, 4409 files were reviewed and 454 cases identified, documented and confirmed (248 in GHD and 206 in CHY)...

Febrile neutropenia (FN) is often observed in hematological malignancies (HEM). Presepsin is also known as soluble CD14 subtype; it is a glycoprotein fragment derived from monocytes and macrophages. We aimed to evaluate the significance of presepsin and other biomarkers for diagnosis of bacteremia in children with HEM. Sixty pediatric patients with different HEM (acute lymphoblastic leukemia 36, acute myeloid leukemia 12, non-Hodgkin lymphoma 10, and Hodgkin disease 2). Thirty age and sex-matched healthy children serving as control were enrolled in this study...

Primary pancreatic lymphoma (PPL) is of very rare occurrence as an extra nodal site of Non-Hodgkin's lymphoma (NHL). It represents less than 1% of NHL. Out of which Burkitt lymphoma of pancreas is of a rare presentation. It usually occurs in children and presenting in adults is uncommon. The prevalence of pancreatic Burkitt lymphoma is not known as the incidence is significantly low. Clinical features of PPL are predominantly nonspecific and can become difficult with associated inflammation of pancreas. Differentiation of lymphoma to adenocarcinoma is important as chemotherapy is the main stay of treatment in lymphoma...

Classic Hodgkin lymphoma (CHL) has four subtypes. Different morphologic variations can be seen in lymph nodes involved by CHL. Primary interfollicular (IF) involvement is not considered a separate subtype but an unusual diagnostically challenging morphologic variant. Our aim was to study the prevalence of IF growth pattern and coexistence of other morphologic variants in lymph nodes involved by CHL, to investigate the diagnostic challenges and clinical importance of this growth pattern, and to find helpful histologic clues in cases with subtle morphologic features to help avoid misinterpretation and missed diagnosis...

BACKGROUND: The first step in the production of chimeric antigen receptor T cells is the collection of autologous T cells using apheresis technology. The procedure is technically challenging, because patients often have low leukocyte counts and are heavily pretreated with multiple lines of chemotherapy, marrow transplantation, and/or radiotherapy. Here, we report our experience of collecting T lymphocytes for chimeric antigen receptor T-cell manufacturing in pediatric and young adult patients with leukemia, non-Hodgkin lymphoma, or neuroblastoma...
