In order to ascertain the effectiveness of nutrient rich diet and dietary counseling on the health status of pediatric acute lymphoblastic leukemia patients, this experimental study was conducted at the Institute of Radiology and Nuclear Medicine, Peshawar. A sample of 30 leukemia patients were divided into experimental and control groups based on written consents. Data regarding demographic characteristics, anthropometric measurements, and retrospective food intakes were recorded on self-constructed questionnaire. Patients in the experimental group received dietary guidelines for nutrient rich diet. Anthropometry, dietary evaluation, and blood nutrients namely serum ferritin, albumin, globulin, total protein and creatinine at 30, 60 and 90 days intervals were assessed. The data showed low height for age and low weight or height at diagnosis indicating malnourishment and wasting among all the patients. After nutritional intervention mean weights of patients in the experimental group increased ...

Relapse of childhood acute lymphoblastic leukaemia (ALL) involving the eye is a rare but challenging problem. Twenty cases occurred in patients treated on the Medical Research Council United Kingdom Acute Lymphoblastic Leukaemia XI and ALL97 trials between 1991 and 2001, representing 2.2% of ALL relapses. Seventeen occurred as a first relapse, either in isolation or combined with relapse at another site, and three occurred as a second relapse. All patients with intraocular disease at first relapse were treated with both chemotherapy and radiotherapy, but the doses and protocols used varied. Eleven of these 17 patients are alive and in complete remission with a median follow up of 4 years 2 months from relapse. All 11 children that were treated with a full chemotherapy relapse protocol, together with local radiotherapy have survived. Patients treated with chemotherapy of shorter duration and intensity, despite radiotherapy and/or bone marrow transplantation, did poorly with only one survivor, ...

Among pediatric acute lymphoblastic leukemia patients who have favorable prognosis, an attempt to reduce the burden of chemotherapy by using lower intensity delayed intensification failed to show better outcomes.
The latest results of clinical trials of more than 125 patients testing an investigational personalized cellular therapy known as CTL019 was recently presented by a University of Pennsylvania research team at the 56th American Society of Hematology (ASH) Annual Meeting. Highlights of the new trial results include a response rate of more than 90 percent among pediatric acute lymphoblastic leukemia patients, and results from the first lymphoma trials testing the approach, including a 100 percent response rate among follicular lymphoma patients and 45 percent response rate among those with diffuse large B cell lymphoma. Dr. Carl June, the research team leader, noted, "We have now treated more than 125 patients in our trials of the chimeric antigen receptor (CAR) therapy CTL019, and with each patient, we learn more and more about the potential of this therapy." The personalized cellular therapy approach begins with patients own immune cells, collected through a procedure similar to dialysis. The ...
The last few decades have turned childhood acute lymphoblastic leukaemia (ALL) from a virtually incurable disease to a disease with 80-90% survival rates. However, this has not come without a cost. Various late effects of the treatment are nowadays well acknowledged, and the survivors have increased cardiovascular (CV) morbidity and mortality. While the treatment of ALL may have direct toxic effects on various organ systems, lifestyle factors affect the CV risk of the survivors as well.. Data on CV health and fitness after treatment with common Nordic protocols since 1986 has been scarce. This thesis aimed to study CV health and fitness and the effects of a 3-month exercise intervention in 16-30-year-old long-term survivors of childhood ALL.. Fitness was poor especially in female survivors. One third reported ≤1h of moderate physical activity (PA) weekly. While the levels of other CV risk factors were similar in survivors and controls, attenuations in vascular endothelium and cardiac function ...

Beside CRS, treatment with BABs and CAR T cells may also be compromised by CNS toxicity. These events may manifest at any time during CRS or as a singular complication [9, 10]. Therefore, staff must be made aware that an intervention with BABs or CAR T cells may potentially necessitate intubation and mechanical ventilation for airway protection, as well as antiepileptic therapy in patients with seizures [9].. A considerable proportion of patients (,50%) who received blinatumomab in a phase 2 trial for acute B-lymphoblastic leukemia experienced neurologic events such as tremor, encephalopathy, cerebellar alteration, or seizures [8]. Thirteen percent of the events were classified as severe or life-threatening. Grade ≥3 neurotoxicity was reported in 13 of 27 patients in an early clinical trial with acute lymphoblastic leukemia patients undergoing CAR T-cell therapy [11]. Recently, cases of lethal cerebral edema in those patients were observed as well [12]. The pathophysiology of these neurotoxic ...

A multiinstitutional cross-sectional study was performed in children with ALL. We included children at least 2 months from diagnosis who were receiving treatment in first remission. Parents described QoL using the PedsQL 4.0 Generic Core Scales and the PedsQL 3.0 Acute Cancer Module. The 206 children on treatment for ALL had overall [median 62.5, 95% confidence interval (CI) 34.8-94.4], physical (median 62.5, 95% CI 18.8-100.0) and psychosocial (median 65.4, 95% CI 38.3-94.2) summary scores that ...
Objective: To test the hypothesis that reduced exposure to common infections in the first year of life increases the risk of developing acute lymphoblastic leukaemia. Design and setting: The United Kingdom childhood cancer study (UKCCS) is a large population based case-control study of childhood cancer across 10 regions of the UK. Participants: 6305 children (aged 2-14 years) without cancer; 3140 children with cancer (diagnosed 1991-6), of whom 1286 had acute lymphoblastic leukaemia (ALL). Main outcome measure: Day care and social activity during the first year of life were used as proxies for potential exposure to infection in infancy.. Results: Increasing levels of social activity were associated with consistent reductions in risk of ALL; a dose-response trend was seen. When children whose mothers reported no regular activity outside the family were used as the reference group, odds ratios for increasing levels of activity were 0.73 (95% confidence interval 0.62 to 0.87) for any social ...
Childhood acute lymphoblastic leukemia (ALL) is a type of cancer in which the bone marrow makes too many immature lymphocytes (a type of white blood cell).

Acute lymphoblastic leukemia is a form of leukemia or cancer of the white blood cells. Acute refers to the undifferentiated, immature state of the circulating lymphocytes ("blasts") and to the rapid progression of disease, which can be fatal in weeks to months if left untreated. May be classified according to the World Health Organization (WHO). Genetic mutations involved in the pathogenesis of acute lymphoblastic leukemia are related with chromosomal translocations. Genes involved in the pathogenesis include t(9;22)(q34;q11.2) BCR-ABL1, t(v;11q23);, t(12;21)(p13;q22) TEL-AML1, t(5;14)(q31;q32)IL3-IGH and t(1;19)(q23;p13.3) TCF3-PBX1. Acute lymphoblastic leukemia must be differentiated from other diseases such as acute myelogenous leukemia, hairy cell leukemia and malignant lymphoma. In 2015 according with the National cancer institute the incidence of acute lymphocytic leukemia is 1.9 per 100,000 individuals and the case fatality rate of 2.3 per 100,000 individuals in the United States.

BackgroundSomatic genetic abnormalities are key initiators and drivers of disease in acute lymphoblastic leukaemia (ALL). Several chromosomal abnormalities have proven clinical utility as prognostic and predictive biomarkers at initial diagnosis. However, the role of genetic biomarkers in relapsed ALL is less well understood and has rarely been studied comprehensively within a clinical trial.AimsTo evaluate the role of genetics in predicting outcome among children with relapsed B-cell precursor ALL treated on the international trial, ALLR3.MethodsWe analysed cytogenetic, copy number alteration (CNA) and sequence mutation data at relapse in representative cohorts of patients. Patients with a very early relapse (,18 months from first diagnosis) and those patients with an isolated marrow relapse who had an early relapse (,6 months from stopping frontline therapy) were treated as clinical high risk (HR) whereas all other patients were treated as clinical standard risk (SR).ResultsClinical HR ...
4Discussion. This study addressed the question of which are the cellular processes that sensitive leukemic cells induced to achieve tolerance to vincristine. To this end, the B-ALL cell line CCRF-SB was gradually exposed until cell proliferation was observed in the presence of 6nM vincristine, and the corresponding proteomic profile was compared to that of cells grown in the absence of the chemotherapeutic drug.. Chemoresistance may be intrinsic or acquired.18 The ability to tolerate high concentrations of chemotherapeutics of an intrinsically resistant cancer cell is not developed as a result of an exposition to the drugs; instead it is the result of genetic abnormalities the cell carries before exposition.18 By contrast, acquired chemoresistance is developed after the cancer cell is exposed to the drug and may be the result of molecular evolution of resistant clones.19 Experimental settings to study acquired chemoresistance include the comparison of matched paired samples at diagnosis and ...

The presence of TEL/AML1 fusion gene in childhood acute lymphoblastic leukaemia (ALL) defines a subgroup of patients with better than average outcome. Around 20% of the patient at point of initial ALL diagnosis are characterised by this fusion transcript from translocation t(12;21)(p12;q22). However, the prognostic significance of this aberration has recently been disputed by the Berlin-Frankfurt-Munster (BFM) study group due to its relatively high incidence found in relapsed patients (19.6% and 21.9%, in two cohorts). Here we wanted to get more data in a long term follow up retrospect investigation by analysing DNA from frozen conserved bone marrow samples of 65 children. In the study presented here only five out of 65 (7.7%) patients selected as childhood B cell precursor acute lymphoblastic leukaemia only treated according to Berlin-Frankfurt-Munster (BFM) ALL relapse trial protocols (ALL-REZ BFM 82-96) (excluding T-lineage and Philadelphia chromosome (Ph)-positive leukaemia) carry this ...

Clinicians who perform radiation therapy (RT) are exposed to radiation, which may negatively affect their health. The present study reports a case of acute lymphoblastic leukemia in a healthcare provider who was exposed to radiation at work; we also present a literature review of this topic. A 45-year-old patient, who had been a radiation oncologist and had been exposed to radiation while performing brachytherapy 10 years ago, complained of chest pain and was suspected of having leukemia based on the results of a blood test in an outpatient clinic. He was diagnosed with acute lymphoblastic leukemia, and subsequently underwent chemotherapy. However, the case died during treatment. Through epidemiological investigation, it was found that the cases cumulative exposure dose based on personal exposure and spatial dose measured during the work period was in the range of 6.08-12.15 mSv. Based on the following considerations, acute lymphoblastic leukemia was highly correlated with the level of radiation to
Background & Objective:Although the antigen expression patterns of acute lymphoblastic leukemia (ALL) are well known, this study attempted to evaluate commonly used immune markers for immunophenotyping of acute leukemia to set the minimum of necessary diagnostic panels by flow cytometry.Methods:This study evaluated 89 patients referred from all over the country to the Iranian Blood Transfusion Organization (IBTO) in Tehran from 2013 to 2015. We compared the immunophenotype patterns of childhood and adult ALLs including 69(77.5%) B-cell lymphoblastic lymphoma (B-LBL), 2(2.2%) Burkitts lymphoma (BL), and 18(20.2%) T-cell lymphoblastic lymphoma (T-LBL) cases using flowcytometry with broad antibody panel.Results:CD19 and CD79a were the most frequent markers for B-LBL while CD7 was the most sensitive marker in T-LBL; the frequency of CD7, CD3, and CD5 antigens were 100%, 38.9%, and 88.9%, respectively. TdT+/CD34+ was significantly higher in adult B-LBLs than children, which indicates blast cells are more

malignancies of blast cells with few identifying characteristics. When cytochemical stains became available, it was possible to divide these objectively into myeloid malignancies and acute leukemias of lymphoid cells. Acute leukemias of lymphoid cells have been subdivided based on morphologic characteristics by the French-American-British (FAB) group (Table 110-2). Using this system, lymphoid malignancies of small uniform blasts (e.g., typical childhood acute lymphoblastic leukemia) were called L1, lymphoid malignancies with larger and more variable size cells were called L2, and lymphoid malignancies of uniform cells with basophilic and sometimes vacuolated cytoplasm were called L3 (e.g., typical Burkitts lymphoma cells). Acute leukemias of lymphoid cells have also been subdivided based on immunologic (i.e., T cell vs. B cell) and cytogenetic abnormalities (Table 110-2). Major cytogenetic subgroups include the t(9;22) (e.g., Philadelphia chromosome-positive acute lymphoblastic leukemia) and ...
High hyperdiploid acute lymphoblastic leukemia ( ALL) is one of the most common malignancies in children. It is characterized by gain of chromosomes, typically +X, +4, +6, +10, +14, +17, +18, and +21, +21; little is known about additional genetic aberrations. Approximately 20% of the patients relapse; therefore it is clinically important to identify risk-stratifying markers. We used SNP array analysis to investigate a consecutive series of 74 cases of high hyperdiploid ALL. We show that the characteristic chromosomal gains are even more frequent than previously believed, indicating that karyotyping mistakes are common, and that almost 80% of the cases display additional abnormalities detectable by SNP array analysis. Subclonality analysis strongly implied that the numerical aberrations were primary and arose before structural events, suggesting that step-wise evolution of the leukemic clone is common. An association between duplication of 1q and +5 was seen ( P = 0.003). Other frequent ...

A type of cancer in which the bone marrow makes too many lymphocytes (a type of white blood cell). Common leukemia also called acute lymphoblastic leukemia and acute lymphoid leukemia (ALL). Generally occurs in children under the age of ten, but it can appear in any age group. ALL or acute means that the disease can get worse quickly. Treatment may depend on the age of the patient as ALL is referred to as either Adult acute lymphoblastic leukemia or Childhood acute lymphoblastic leukemia.
Acute lymphoblastic leukemia is the most common leukemia in children, with approximately 3,000 new patients diagnosed each year in the United States.
