  2. Acute myeloid leukemia in the older patient.

    2003-10-15

    Acute myeloid leukemia (AML) is an extremely heterogeneous disorder. The biology of AML is incompletely understood, but much data indicates that older patients have a more biologically diverse and chemotherapy resistant form of AML that is quite different from that seen in the younger patients. Approximately 60% of AML cases are in patients greater than 60 years of age, so the predominant burden is in older patients. This problem will be magnified in the future, because the US population is both growing and aging. When one examines the treatment outcomes of older AML patients over the last three decades, there is little progress in long-term survival. Nine major published randomized placebo controlled trials of myeloid growth factors given during induction for AML have been conducted. All of these trials with one exception demonstrated no significant impact on the clinical outcomes of complete response (CR) rate, disease-free, and overall survival. However, the duration of neutropenia was consistently and uniformly reduced by the use of growth factor in all nine of these trials. Because of the favorable impact of the colony-stimulating factors (CSFs) on resource use, antibiotic days, hospital days, etc., it can be more economical and beneficial to use CSFs in AML than to withhold use. The overall dismal outlook for the older AML patient can only be altered by clinical trials with new therapeutic agents. New cellular and molecularly targeted agents are entering clinical trials and bring hope for progress to this area of cancer therapy. PMID:14563517

    2009-01-01

    The prognosis for the majority of acute myeloid leukemia (AML) patients without a donor is dismal whether conventional salvage chemotherapy regimens or investigational strategies are used, and most of these patients will eventually die of their disease. There is no standard chemotherapy regimen that provides durable complete remission in patients with refractory AML. Beneficial effects of amifostine, either alone or in combination with conventional chemotherapy, was demonstrated in patients w...

    Objective To highlight the current understanding of mixed phenotype acute leukemia (MPAL).Data sources We collected the relevant articles in PubMed (from 1985 to present),using the terms "mixed phenotype acute leukemia","hybrid acute leukemia","biphenotypic acute leukemia",and "mixed lineage leukemia".We also collected the relevant studies in WanFang Data base (from 2000 to present),using the terms "mixed phenotype acute leukemia" and "hybrid acute leukemia".Study selection We included all relevant studies concerning mixed phenotype acute leukemia in English and Chinese version,with no limitation of research design.The duplicated articles are excluded.Results MPAL is a rare subgroup of acute leukemia which expresses the myeloid and lymphoid markers simultaneously.The clinical manifestations of MPAL are similar to other acute leukemias.The World Health Organization classification and the European Group for Immunological classification of Leukaemias 1998 cdteria are most widely used.MPAL does not have a standard therapy regimen.Its treatment depends mostly on the patient's unique immunophenotypic and cytogenetic features,and also the experience of individual physician.The lack of effective treatment contributes to an undesirable prognosis.Conclusion Our understanding about MPAL is still limited.The diagnostic criteria have not been unified.The treatment of MPAL remains to be investigated.The prognostic factor is largely unclear yet.A better diagnostic cdteria and targeted therapeutics will improve the therapy effect and a subsequently better prognosis.

    As the world population ages, the comorbidity burden in acute myeloid leukemia (AML) patients increases. Evidence on how to integrate comorbidity measures into clinical decision-making is sparse. We determined the prognostic impact of comorbidity and World Health Organization Performance Status (PS......) on achievement of complete remission and mortality in all Danish AML patients treated between 2000 and 2012 overall and stratified by age. Comorbidity was measured using a modified version of the Charlson Comorbidity Index, with separate adjustment for pre-leukemic conditions. Of 2792 patients, 1467...

    Full Text Available Background: Heparanase is an endoglycosidase that degrades heparin sulfate, the main polysaccharide constituent of the extracellular matrix and basement membrane. Expression of the heparanase gene is associated with the invasive, angiogenic, and metastatic potential of diverse malignant tumors and cell lines. Aim of the study: to investigate possible relation/correlation between Heparanase gene expression and quantitation in pediatric Acute leukemia patients and clinicopathologic variables as well as patients outcome in an attempt to determine it′s prognostic value and the possibility of using it as a new target for treatment. Patients and methods: Forty pediatric acute leukemia patients (20 acute myeloid leukemia (AML&20 acute lymphoblastic leukemia(ALL as well as 11 normal volunteers were analyzed for the expression and level of Heparanase gene using real time quantitative reverse transcriptase polymerase chain reaction (RTQ-PCR to investigate a possible relation, association, or correlation with the clinical and laboratory features of patients at diagnosis, and patient outcome after treatment and follow up. Results: Comparing the 3 groups as regards the Heparanase gene level there was high statistical significant difference (p<0.001 being maximum in AML and minimum in controls, with mean Relative quantitation (RQ level 2336.2± 10405.2 in AML ,median 8.0 and range (3.1-46543.0 , while mean RQ in ALL was 1.7±1.0 ,median 1.7 and range (0.1-3.1 and in controls mean was 0.8±0.3, median 0.8 and range (0.4-1.4.Comparison between each 2 groups as regards heparanase level was of high statistically significant difference, p value being (p<0.001 when comparing AML/ALL and AML/controls and (p=0.035 when comparing ALL/controls. Cut off value for heparanase gene was calculated using Roc curve and was found to be 1.413 with 80% sensitivity and 100% specificity. According to this cut off level, 20/20 (100% AML cases were heparanase positive, 12

    2016-09-01

    Invasive fungal disease (IFD) represents an important complication in patients with acute lymphoid leukemia (ALL). The objectives of this study were to determine the prevalence of IFD in ALL patients with neutropenia, identify factors associated with IFD, and estimate the impact of IFD on the outcome. All patients with ALL who developed febrile neutropenia from 1987 to 2013 were evaluated. Cases of IFD were classified as proven or probable. Factors associated with IFD were evaluated by comparing episodes with and without a diagnosis of IFD. Among 350 episodes of febrile neutropenia, 31 IFDs were diagnosed (8.8%). Prolonged neutropenia was the only factor associated with IFD caused by yeasts. Factors associated with IFD caused by molds by multivariate analysis were the period after 2008, receipt of allogeneic transplant, relapsed ALL and prolonged neutropenia. Patients in relapse should receive induction chemotherapy in rooms with HEPA filter and receive antifungal prophylaxis. PMID:26949001

  18. Splenic microabscesses in patients with acute myelogenous leukemia

    Eight patients with acute myelogenous leukemia in complete remission after induction chemotherapy got septic fever. Fever was unresponsive to broad-spectrum antibiotic therapy. Ultrasonography showed multiple 0,5-2 cm in diameter, anechoic densities and some 1-3 cm ''target'' appearances in spleen and liver. Computed tomography demonstrated multiple, round, 0,5-2 cm areas of diminished attenuation in spleen and liver, which did not enhance like the surrounding parenchyma. These microabscesses increased in size and number of lesions without equivalent antifungal therapy and decreased or disappeared after specific treatment. Candida-infection was assured by histologic liver specimen in four patients, fungal organisms were seen microscopically in liver-biopsy in one patient and at autopsy one patient was found to have candida disseminated to the spleen, liver, kidneys, lungand CNS.

    Immunophenotype is critical for diagnosing common B-cell acute lymphoblastic leukemia (common ALL) and detecting minimal residual disease.We developed a protocol to explore the immunophenotypic profiles of common ALL based on the expression levels of the antigens associated with B lymphoid development,including IL-7Rα (CD127),cytoplasmic CD79a (cCD79a),CD19,VpreB (CD179a),and slgM,which are successive and essential for progression of B cells along their developmental pathway.Analysis of the immunophenotypes of 48 common ALL cases showed that the immunophenotypic patterns were highly heterogeneous,with the leukemic cell population differing from case to case.Through the comprehensive analysis of immunophenotypic patterns,the profiles of patient-specific composite leukemia cell populations could provide detailed information helpful for the diagnosis,therapeutic monitoring,and individualized therapies for common ALL.

  12. Treatment of Acute Myeloid Leukemia in Adolescent and Young Adult Patients

    Guldane Cengiz Seval

    2015-03-01

    Full Text Available The objectives of this review were to discuss standard and investigational treatment strategies for adolescent and young adult with acute myeloid leukemia, excluding acute promyelocytic leukemia. Acute myeloid leukemia (AML in adolescent and young adult patients (AYAs may need a different type of therapy than those currently used in children and older patients. As soon as AML is diagnosed, AYA patient should be offered to participate in well-designed clinical trials. The standard treatment approach for AYAs with AML is remission induction chemotherapy with an anthracycline/cytarabine combination, followed by either consolidation chemotherapy or stem cell transplantation, depending on the ability of the patient to tolerate intensive treatment and cytogenetic features. Presently, continuing progress of novel drugs targeting specific pathways in acute leukemia may bring AML treatment into a new era.

    Therapy-related acute myeloid leukemia (t-AML) is a rare and almost always fatal late side effect of antineoplastic treatment involving chemotherapy, radiotherapy or the two combined. The present retrospective study intended to characterize t-AML patients that were diagnosed and treated in a single referral to an oncological institution in North Portugal. Over the past 10 years, 231 cases of AML were diagnosed and treated at the Portuguese Institute of Oncology of Porto, of which 38 t-AML cases were identified. Data regarding the patient demographics, primary diagnosis and treatment, age at onset of therapy-related myeloid neoplasm, latency time of the neoplasm, cytogenetic characteristics, AML therapy and outcome were collected from medical records. A previous diagnosis with solid tumors was present in 28 patients, and 10 patients possessed a history of hematological conditions, all a lymphoproliferative disorder. Breast cancer was the most frequent solid tumor identified (39.5% of all solid tumors diagnosed). The mean latency time was 3 years. In the present study, t-AML patients were older (PAML patients. The overall survival time was observed to be significantly poorer among individuals with t-AML (PAML and those with de novo AML (P=0.983). Additionally, patients with promyelocytic leukemia possess a good prognosis, even when AML occurs as a secondary event (P=0.98). To the best of our knowledge, the present study is the first to evaluate t-AML in Portugal and the results are consistent with the data published previously in other populations. The present study concludes that although t-AML demonstrates a poor prognosis, this is not observed among younger patients or promyelocytic leukemia patients.

    2004-01-01

    @@ Acute promyelocytic leukemia (APL) is the M3 subtype of the French-American-British (FAB) classification of acute myeloid leukemia (AML). Hemophilia is a congenital bleeding disorder characterized by a deficiency of coagulation factor VIII or IX. In our center, more than one thousand patients with haemophilia A have been treated since 1980.1 In June 2002, APL was first diagnosed in one person with haemophilia (PWH). The coincidence of these two diseases led to challenges in developing a treatment strategy.

  17. /sup 32/P and acute leukemia: development of leukemia in a patient with hemoglobin Yakima

    Bagby, G.C. Jr.; Richert-Boe, K.; Koler, R.D.

    1978-08-01

    In 1954 a then 31-yr-old male was found to have erythrocytosis. Over the ensuing decade he received 72 mCi /sup 32/P. In 1964 his daughters were found to have erythrocytosis. Further investigation led to the discovery of hemoglobin Yakima, a variant with high oxygen affinity. He received no further therapy and was well until 1975, when he developed the preleukemic syndrome. Within 12 mo he developed acute nonlymphocytic leukemia accompanied by fetal erythropoiesis. Because the initial discovery of this type of hemoglobinopathy came 27 yr after the introduction of /sup 32/P for use in the treatment of polycythemia vera, and because there are now known to be more than 39 different high-oxygen-affinity hemoglobins, we anticipate that more patients such as ours have been exposed to /sup 32/P. The exposed population should be closely followed, since this will likely permit assessment of the risk of /sup 32/P-induced leukemia in a nonneoplastic condition.

    Acute biphenotypic leukemias or mixed phenotype acute leukemias (MPAL) are rare and considered high risk. The optimal treatment and the role of allogeneic hematopoietic stem cell transplantation (alloHCT) are unclear. Most prior case series include only modest numbers of patients who underwent transplantation. We analyzed the outcome of 95 carefully characterized alloHCT patients with MPAL reported to the Center for International Blood and Marrow Transplant Research between 1996 and 2012. The median age was 20 years (range, 1 to 68). Among the 95 patients, 78 were in first complete remission (CR1) and 17 were in second complete remission (CR2). Three-year overall survival (OS) of 67% (95% confidence interval [CI], 57 to 76), leukemia-free survival of 56% (95% CI, 46 to 66), relapse incidence of 29% (95% CI, 20 to 38), and nonrelapse mortality of 15% (95% CI, 9 to 23) were encouraging. OS was best in younger patients (acute myelogenous leukemia or 359 acute lymphoblastic leukemia cases. MPAL patients had more acute and a trend for more chronic graft-versus-host disease. No difference was observed between patients who underwent transplantation in CR1 versus those who underwent transplantation in CR2. AlloHCT is a promising treatment option for pediatric and adult patients with MPAL with encouraging long-term survival. PMID:26903380

In the present study, 47 MPAL, 60 lymphoid antigen-positive acute myeloid leukemia (Ly+AML), and 90 acute myeloid leukemia with common myeloid immunophenotype (Ly−AML) patients were investigated. We found that, in MPAL patients, there were high proportions of blast cells in bone marrow and incidence of hepatosplenomegaly, lymphadenopathy, and Philadelphia chromosome. The overall s...

  11. Clinical and microbiological characteristics of perianal infections in adult patients with acute leukemia.

    Chien-Yuan Chen

    Full Text Available BACKGROUND: Perianal infection is a common problem for patients with acute leukemia. However, neutropenia and bleeding tendency are relatively contraindicated to surgical intervention. The epidemiology, microbiology, clinical manifestations and outcomes of perianal infection in leukemic patients are also rarely discussed. METHOD: The medical records of 1102 adult patients with acute leukemia at a tertiary medical center in Taiwan between 2001 and 2010 were retrospectively reviewed and analyzed. RESULT: The prevalence of perianal infection was 6.7% (74 of 1102 in adult patients with acute leukemia. Twenty-three (31% of the 74 patients had recurrent episodes of perianal infections. Patients with acute myeloid leukemia had higher recurrent rates than acute lymphoblastic leukemia patients (p = 0.028. More than half (n = 61, 53% of the perianal infections were caused by gram-negative bacilli, followed by gram-positive cocci (n = 36, 31%, anaerobes (n = 18, 15% and Candida (n = 1, 1% from pus culture. Eighteen patients experienced bacteremia (n = 24 or candidemia (n = 1. Overall 41 (68% of 60 patients had polymicrobial infection. Escherichia coli (25% was the most common micro-organism isolated, followed by Enterococcus species (22%, Klebsiella pneumoniae (13%, and Bacteroides species (11%. Twenty-five (34% of 74 patients received surgical intervention. Acute leukemia patients with surgically managed anal fistulas tended to have fewer recurrences (p = 0.067. Four (5% patients died within 30 days after diagnosis of perianal infection. Univariate analysis of 30-day survival revealed the elderly (≧ 65 years (p = 0.015 and patients with shock (p<0.001 had worse outcome. Multivariate analysis showed septic shock to be the independent predictive factor of 30-day crude mortality of perianal infections (p = 0.016. CONCLUSION: Perianal infections were common and had high recurrence rate in adult patients with acute

  12. Drug screen in patient cells suggests quinacrine to be repositioned for treatment of acute myeloid leukemia

    To find drugs suitable for repositioning for use against leukemia, samples from patients with chronic lymphocytic, acute myeloid and lymphocytic leukemias as well as peripheral blood mononuclear cells (PBMC) were tested in response to 1266 compounds from the LOPAC1280 library (Sigma). Twenty-five compounds were defined as hits with activity in all leukemia subgroups (<50% cell survival compared with control) at 10 μM drug concentration. Only one of these compounds, quinacrine, showed low activity in normal PBMCs and was therefore selected for further preclinical evaluation. Mining the NCI-60 and the NextBio databases demonstrated leukemia sensitivity and the ability of quinacrine to reverse myeloid leukemia gene expression. Mechanistic exploration was performed using the NextBio bioinformatic software using gene expression analysis of drug exposed acute myeloid leukemia cultures (HL-60) in the database. Analysis of gene enrichment and drug correlations revealed strong connections to ribosomal biogenesis nucleoli and translation initiation. The highest drug–drug correlation was to ellipticine, a known RNA polymerase I inhibitor. These results were validated by additional gene expression analysis performed in-house. Quinacrine induced early inhibition of protein synthesis supporting these predictions. The results suggest that quinacrine have repositioning potential for treatment of acute myeloid leukemia by targeting of ribosomal biogenesis

  20. The mortality and response rate after FLANG regimen in patients with refractory/relapsed acute leukemia

    Vali A Mehrzad

    2012-01-01

    Full Text Available Background: Oncologists today are greatly concerned about the treatment of relapsed/refractory acute leukemia. FLANG regimen, combination of novantron, cytarabine, fludarabine, and granulocyte-colony stimulating factor, has been used in treatment of refractory/relapsed acute leukemia since 1990s. The present study has evaluated mortality and response rate of this regimen. Materials and Methods: In this study, 25 patients with refractory/relapsed acute leukemia aged 15-55 years underwent FLANG regimen at Seyed-Al-Shohada Hospital, Isfahan, Iran during 2008-2009. One month later, bone marrow samples were taken to evaluate the responsiveness to treatment. Participants were followed for a year. The data was analyzed by student-t and chi-square tests, logistic, and Cox regression analysis, and Kaplan-Meier curves in SPSS 19. Results: Out of the 25 patients, 8 patients (32% had acute lymphoblastic leukemia (5 refractory and 3 relapsed cases and 17 subjects had acute myeloid leukemia (7 refractory and 10 relapsed cases. According to the bone marrow biopsies taken one month after FLANG regimen, 10 patients (40% had responded to treatment. Five patients of the 10 responders underwent successful bone marrow transplantation (BMT. On the other hand, 13 patients (52%, who had not entered the CR period, died during the follow-up. Logistic regression analysis did not reveal any significant associations between disease type and responsiveness to treatment. Conclusion: This study indicated higher rates of unresponsiveness to treatment while its mortality rate was comparable with other studies. Overall, according to limitations for BMT (as the only chance for cure in Iran, it seems that FLANG therapy is an acceptable choice for these patients.

    1981-09-01

    Chromosome and cytologic studies were performed on three Down's syndrome (DS) patients with acute nonlymphocytic leukemia (ANLL). All three patients had an aneuploid clone in their leukemic cells: 50,XX, +6, +19, +21, +22, 48,XX, +8, +21, and 47,XY, +8, -21, +dic(21;21)(p13;p11). Every patient appeared to have acute undifferentiated leukemia when the blast cells were examined with Wright-Giemsa stain; cytochemistry studies, however, showed that the leukemic blasts were in an early stage of myeloid differentation. The two patients with +8 had a preleukemic phase; the blast cells of the patient with an extra no. 19 and no. 22 could not be differentiated morphologically from those of the two patients with an extra no. 8. Our findings and a review of data on 40 other patients suggest that most DS children with ANLL have hyperdiploidy, which is usually related to gains of C, F, and/or G chromosomes.

    Immunophenotype is critical for diagnosing common B-cell acute lymphoblastic leukemia (common ALL) and detecting minimal residual disease. We developed a protocol to explore the immunophenotypic profiles of common ALL based on the expression levels of the antigens associated with B lymphoid development, including IL-7R alpha (CD127), cytoplasmic CD79a (cCD79a), CD19, VpreB (CD179a), and sIgM, which are successive and essential for progression of B cells along their developmental pathway.

    1984-01-01

    Peripheral blood mononuclear cells (PBM) isolated from 23 patients with acute lymphoblastic leukemia (ALL) and 24 with acute non-lymphoblastic leukemia (ANLL) were studied for binding and mobility of Concanavalin A (Con A) receptors, using fluorescent Con A (F-Con-A). The cap forming ability of PBM from all patients was 18.7 (+/- 9.3%) and 18.9 (+/- 9.9%) for ANLL patients at the time of diagnosis or during relapse. During clinical complete remission the cap forming ability of the PBM did not change significantly. No correlation was observed between the percentage of blasts present in the peripheral blood at the time of examination and the extent of cap formation, for both types of leukemia. The pattern of F-Con-A binding to PBM in ANLL patients was different compared to that seen in ALL. In ANLL, the fluorescent stain was concentrated in a round body on the cell ("button form") after binding to the membrane, while the rest of the cell showed almost no fluorescence. The present results indicate that PBM cells from patients with acute leukemia are characterized by a high degree of Con-A receptor mobility. PMID:6471903

  9. Ultrasound and MR Findings of Aleukemic Leukemia Cutis in a Patient with Complete Remission of Acute Lymphoblastic Leukemia: A Case Report

    Kim, Min Sung; Jee, Won Hee; Kim, Sun Ki; Lee, So Yeon; Lim, Gye Yeon; Park, Gyeong Sin; Lee, Seok [Catholic University of Korea College of Medicine, Seoul (Korea, Republic of)

    2010-12-15

    Aleukemic leukemia cutis is an extremely rare condition characterized by the infiltration of leukemic cells in skin without blasts in the peripheral blood. Leukemia cutis is considered a grave prognostic sign, thus early diagnosis is important. Leukemia cutis usually occurs in patients with myeloid leukemia. To the best of our knowledge, there has been no report regarding the radiological findings of aleukemic leukemia cutis, which is probably due to the presence of the skin changes in most patients. We report the ultrasound and MR findings of aleukemic leukemia cutis, even without the skin manifestation in patients with a history of complete remission of the acute lymphoblastic leukemia following an allogeneic peripheral blood stem cell transplantation

    Full Text Available Introduction. Skin findings in leukemias may be divided into specific lesions (leukemia cutis and non-specific lesions (leukemids which may be found in up to 80% of all patients with leukemias. The leukemids vary clinically and they are usually a manifestation of bone marrow or immunologic impairment, but also Sweet syndrome, pyoderma gangrenosum, erythroderma, maculopapular exanthema, prurigo-like papules, generalized pigmentation, follicular mucinosis, generalized pruritus may be found during the course of leukemia. Case report. We report a 70-year-old male with a 3-month history of erythema, papules and pustules on the face, ears and neck and over a month history of refractory anemia, anorexia, weight loss, malaise, and fever. Physical examination revealed symmetric erythematous, violaceous papules, papulo-nodules and plaques with slate scale and sparse, small pustules on the face, earlobes and neck. Histopathologic findings of involved skin showed diffuse mixed inflammatory cell infiltrate with perifollicular accentuation and focal granulomatous inflammation in the papillary and upper reticular dermis. Extensive checkup revealed the presence of acute myeloid leukemia French- American-British (FAB classification subtype M2, with signs of three-lineage dysplasia. The patient was treated by L6 protocol which led to complete remission, both in bone marrow and skin, but after seven months he had relapse of leukemia with the fatal outcome. Conclusion. This case indicates the importance of skin eruptions in the context of hematological malignancies.

    Translocation of the LYL1 oncogene are rare in T-cell acute lymphoblastic leukemia, whereas the homologous TAL1 gene is rearranged in approximately 20% of patients. Previous gene-expression studies have identified an immature T-cell acute lymphoblastic leukemia subgroup with high LYL1 expression in the absence of chromosomal aberrations. Molecular characterization of a t(7;19)(q34;p13) in a pediatric T-cell acute lymphoblastic leukemia patient led to the identification of a translocation betw...

  1. Distinguishing the Causes of Pulmonary Infiltrates in Patients With Acute Leukemia.

    Nucci, Marcio; Nouér, Simone A; Anaissie, Elias

    2015-06-01

    Pulmonary infiltrates are commonly observed in patients with acute leukemia (AL), particularly acute myeloid leukemia, who undergo remission induction therapy. The mortality rate is unacceptably high and depends on 3 factors: the host (performance status, comorbidities, and frailty), the etiology of the infiltrates and the type of response to antileukemic therapy. The approach to the diagnosis of pulmonary infiltrates in patients with AL includes a medical history, thorough physical examination, radiologic pattern of the infiltrates (focal vs. diffuse), and timing of their appearance in relation to the start of antileukemic therapy (early, ie, within the first 2 weeks or late). Localized infiltrates are most commonly caused by bacterial (early) and fungal infections (late). Diffuse early infiltrates might be caused by leukemic infiltration of the lungs, pulmonary hemorrhage and/or edema, diffuse alveolar damage, viral pneumonia, and rarely transfusion-related acute lung injury (TRALI) or the differentiation syndrome. Similar to the early phase, pulmonary edema, viral pneumonia, and rarely TRALI might cause diffuse infiltrates during the late phase, in addition to immune reconstitution and pneumocystosis, particularly among patients with acute lymphoblastic leukemia. Diagnostic tests, invasive and noninvasive, can be particularly useful to establish the diagnosis. Early intervention is critical and is based on the most likely diagnosis with modification when the etiology is confirmed. PMID:26297289

    Full Text Available Purpose: The aim of this study was to evaluate the incidence of aberrant phenotypes and possible prognostic value in peripheral and bone marrow blood mononuclear cells of Iranian patients with AML. Methods: 56 cases of de novo AML (2010-2012 diagnosed by using an acute panel of monoclonal antibodies by multiparametric flowcytometry. Immunophenotyping was done on fresh bone marrow aspirate and/or peripheral blood samples using the acute panel of MoAbs is stained with Phycoerythrin (PE /fluorescein isothiocyanate (FITC, Allophycocyanin (APC and Peridinin-chlorophyll protein complex (perCP. We investigated Co-expression of lymphoid-associated markers CD2, CD3, CD7, CD 10, CD19, CD20 and CD22 in myeloblasts. Results: Out of the 56 cases, 32 (57.1% showed AP. CD7 was positive in 72.7% of cases in M1 and 28.5% in M2 but M3 and M4 cases lacked this marker. We detected CD2 in 58.35 of M1cases, 21.40% of M2 cases, 33.3 of M3 and 20% of M5; but M4 patients lacked this marker. The CBC analysis demonstrated a wide range of haemoglobin concentration, Platelet and WBC count which varied from normal to anaemia, thrombocytopenia to thrombocytosis and leukopenia to hyper leukocytosis. Conclusions: Our findings showed that CD7 and CD2 were the most common aberrant marker in Iranian patients with AML. However, we are not find any significant correlation between aberrant phenotype changing and MRD in our population. Taken together, this findings help to provide new insights in to the investigation of other aberrant phenotypes that may play roles in diagnosis and therapeutic of AML.

    Roeker, LE; Larson, DR; Kyle, RA; Kumar, S; Dispenzieri, A; Rajkumar, SV

    2013-01-01

    The purpose of this study was to determine if there is an increased risk of acute leukemia and myelodysplastic syndromes (MDS) in persons with monoclonal gammopathy of undetermined significance (MGUS). We used a large population-based cohort of individuals systematically screened for the presence or absence of MGUS. MGUS status was then linked to the diagnosis of acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL) and MDS. A total of 17 315 patients age 50 and older (605 MGUS and...

  6. Acute lymphocytic Leukemia masquerading as acute osteomyelitis

    Two children each developed a focal destructive bone lesion accompanied by intermittent fever, swelling, tenderness and elevated ESR. Blood counts were normal; bone marrow aspiration showed acute leukemia. The bone lesions healed in both patients after anti-leukemic therapy. We suggest that the similar roentgenographic appearance of osteomyelitis, bone infarction and focal destructive lesions in leukemia probably reflects a common, basically ischemic process of bone. (orig.)

  7. Kinetics of indium-111-labeled leukemic cells in patients with acute non-lymphocytic leukemia

    The kinetics of autologous leukemic cells labeled with In-111 oxine were studied in 5 patients with acute myeloblastic leukemia (AML) and one patient with acute premyelocytic leukemia (APL), and kinetics of OKM1 monoclonal antibody-treated leukemic cells were studied in one patient with acute monoblastic leukemia (AMoL). Recoveries of 33.7 +- 23.3%(range, 22.0 to 48.1%) were achieved at 10min after injection of In-111 oxine labeled leukemic cells in AML and APL patients. However, in a patient with AMoL recovery of 12.3% was only achieved at 10min after injection of OKM1-treated leukemic cells. Clearance of the activity from blood was rapid up to one in all patients. The clearance curve of the activity in 5 AML patients showed a hump or a plateau from one to 5hr after injection of labeled leukemic cells. In APL patient and AMoL patient, however, this hump or plateau was not noted. In AML and APL patients the activity over the spleen was higher than that of over the liver at from 30min to 3hr after and showed a plateau or gradual rising thereafter. In a patient with AMoL, the hepatic activity was higher than the splenic activity at 30min after, but thereafter the latter became higher than the former. Liver activity curves showed transient fall at 3hr after and then gradual uprising in all patients. In a patient with APL, high activity was noted over the kidneys. This rose to a maximum after 3hr and then decreased rapidly. Since In-111 oxine stays firmly attached to the cells in spite of the possibility of radiation damage in a long-term survey, it seems an ideal label for studying leukemic cell kinetics

    2013-04-01

    Full Text Available Introduction: Autologous haemopoietic stem cell transplantation (SCT is an important treatment modality for patients with acute myeloid leukemia with low and intermediate risk disease. It has served advantages over allogenic transplantation, because it does not need a matched donor, there is no graft versus host disease, there are less complications and a faster immune reconstitution than in the allo-setting. The disadvantage is the lack of the graft versus leukaemia effect.

  13. Morbidity associated to the transfusion support in pediatric patients with acute leukemia in the National Cancer Institute

    Acute leukemia represents the most common cancer in pediatrics. The current treatments made necessary a hematological support which increases the risks of complications, like fever, immunologic reaction, infections and, graft versus host disease. The objective of the present study was to determine the morbidity associated with transfusion support in pediatric patients with acute leukemia. In the pediatric population with diagnosis of acute leukemia in the INC during one and half year, the morbidity associated with transfusions was low and couldn't be related to the treatment given to the transfused products

    Ganguly, Anasua; Kaliki, Swathi; Mohammad, Faraz Ali; Mishra, Dilip K; Vanajakshi, S; Reddy, Vijay Anand

    2016-01-01

    Second primary tumor (SPT) is defined as a second tumor that presents either simultaneously or after the diagnosis of an index tumor. Second primary malignancies are the leading cause of death in patients with heritable retinoblastoma (RB). Acute lymphoblastic leukemia (ALL), as SPT in RB patients, is extremely rare. To the best of our knowledge, only five cases of ALL as SPT in patients with RB has been documented in the literature. Herein, we report a case of a 6-year-old girl with bilateral RB, who developed ALL during the course of treatment of RB. This case highlights the importance of reviewing blood investigations regularly to diagnose leukemia as SPT in RB and also the necessity for proper counseling and lifelong follow-up in these patients.

    2015-01-01

    Full Text Available Acute acalculous cholecystitis is a rare complication in the treatment of acute myeloblastic leukemia. Diagnosis of acute acalculous cholecystitis remains difficult during neutropenic period. We present two acute myeloblastic leukemia patients that developed acute acalculous cholecystitis during chemotherapy-induced neutropenia. They suffered from fever, vomiting and acute pain in the epigastrium. Ultrasound demonstrated an acalculous gallbladder. Surgical management was required in one patient and conservative treatment was attempted in the other patient. None treatment measures were effective and two patients died. Acute acalculous cholecystitis is a serious complication in neutropenic patients. Earlier diagnosis could have expedited the management of these patients.

    The advent of new cell-based immunotherapies for leukemia offers treatment possibilities for certain leukemia subgroups. The wider acceptability of these new technologies in clinical practice will depend on its impact on survival and costs. Due to the small patient groups who have received it, these aspects have remained understudied. This non-randomized single-center study evaluated medical costs and survival for acute myeloid leukemia between 2005 and 2010 in 50 patients: patients treated with induction and consolidation chemotherapy (ICT) alone; patients treated with ICT plus allogeneic hematopoietic stem cell transplantation (HCT), which is the current preferred post-remission therapy in patients with intermediate- and poor-risk AML with few co-morbidities, and patients treated with ICT plus immunotherapy using autologous dendritic cells (DC) engineered to express the Wilms' tumor protein (WT1). Total costs including post- consolidation costs on medical care at the hematology ward and outpatient clinic, pharmaceutical prescriptions, intensive care ward, laboratory tests and medical imaging were analyzed. Survival was markedly better in HCT and DC. HCT and DC were more costly than ICT. The median total costs for HCT and DC were similar. These results need to be confirmed to enable more thorough cost-effectiveness analyses, based on observations from multicenter, randomized clinical trials and preferably using quality-adjusted life-years as an outcome measure.

  1. Invasive fungal infection (IFI) in two pediatric patients with acute leukemia. Case report

    At present over 70% of children with malignancies can be successfully cured although this is achieved at the cost of increased incidence of major complications. Fungal infections account for some 10% of all infections and, in severely immunosuppressed patients, they are still the cause of a high mortality rate (50-95%). As a result the prevention and treatment of adverse effects of antineoplastic therapy is of the most importance and can be a factor determining the success of such treatment. This paper contains two case reports of adolescent female patients diagnosed with acute leukemia who developed invasive fungal infections (IFI) in the course of intensive chemotherapy. (authors)

  5. CHARACTERISTICS OF PHAGOCYTIC CELLS IN PATIENTS WITH ACUTE LEUKEMIA WITH AN INFECTIOUS SYNDROME

    S. V. Plotnikova

    2013-01-01

    Full Text Available Abstract. The aim of this study was to investigate some characteristics of neutrophils and monocytes in patients with acute leukemia, depending on presence of an infectious syndrome, as based on studying of CD16, CD64, HLA-DR receptors, along with assaying myeloperoxidase (MPO and functional activity of the cells. Infectious syndrome in acute leukemia patients was accompanied by changes in antibody-dependent cytotoxicity against neutrophils (decreased CD16 and increase in CD64 expression, lower phagocytic capacity of the cells, and myeloperoxidase deficiency of neutrophils and monocytes. In patients with inflammatory manifestations of infectious syndrome (i.e., acute tonsillitis, bronchitis, pneumonia, etc., the signs of neutrophilic insussiciency were more pronounced, i.e., CD16+ neutrophils comprised 24.36±7.43%, as compared with 74.21±5.43% in controls, p < 0.001; MPO positivity was detected in 29.15±12.6% of the cells against 96.1±1.94% in controls, p < 0.01; MPO expression: 5.34±3.07 MFI, with 32.9±10.76 in controls, p < 0,05. These data suggest significant disturbances of anti-infectious elimination mechanisms.

    2016-01-01

    The aim of this study was to assess the effect of acupressure, applied at P6 (Neiguan) acupuncture point, on chemotherapy-induced nausea and vomiting in patients with acute myeloblastic leukemia. This was a randomized controlled trial conducted on patients with myeloblastic leukemia. A total of 90 patients, who received the same chemotherapy regimen and antiemetic therapy, were included in the study as 30 patients in the control group, 30 patients in the band group, and 30 patients in the pressure group. Although acupressure was applied by placing wristbands at P6 acupuncture point of both wrists in patients of the band group for totally 4 days, acupressure was applied with the use of finger pressure in patients of the pressure group for totally 4 days. No intervention was made in patients of the control group other than the routine antiemetic therapy. The data of the study were collected by using a questionnaire and nausea-vomiting chart. Severity of nausea-vomiting was assessed by using the visual analog scale on this chart. It was determined that the acupressure band applied to the patients included in the study reduced number and severity of nausea-vomiting (P acupressure applied with pressure did not affect number and severity of nausea-vomiting (P > .05). It was found that the acupressure band was effective for reducing the chemotherapy-induced nausea and vomiting. PMID:27501207

  7. Acute leukemia in early childhood

    M. Emerenciano

    2007-06-01

    Full Text Available Acute leukemia in early childhood is biologically and clinically distinct. The particular characteristics of this malignancy diagnosed during the first months of life have provided remarkable insights into the etiology of the disease. The pro-B, CD10 negative immunophenotype is typically found in infant acute leukemia, and the most common genetic alterations are the rearrangements of the MLL gene. In addition, the TEL/AML1 fusion gene is most frequently found in children older than 24 months. A molecular study on a Brazilian cohort (age range 0-23 months has detected TEL/AML1+ve (N = 9, E2A/PBX1+ve (N = 4, PML/RARA+ve (N = 4, and AML1/ETO+ve (N = 2 cases. Undoubtedly, the great majority of genetic events occurring in these patients arise prenatally. The environmental exposure to damaging agents that give rise to genetic changes prenatally may be accurately determined in infants since the window of exposure is limited and known. Several studies have shown maternal exposures that may give rise to leukemogenic changes. The Brazilian Collaborative Study Group of Infant Acute Leukemia has found that mothers exposed to dipyrone, pesticides and hormones had an increased chance to give birth to babies with infant acute leukemia [OR = 1.48 (95%CI = 1.05-2.07, OR = 2.27 (95%CI = 1.56-3.31 and OR = 9.08 (95%CI = 2.95-27.96], respectively. This review aims to summarize recent clues that have facilitated the elucidation of the biology of early childhood leukemias, with emphasis on infant acute leukemia in the Brazilian population.

    Background Mitochondrial DNA (mtDNA) alterations, including mtDNA copy number and mtDNA 4977 bp common deletion (CD), are key indicators of irradiation-induced damage. The relationship between total body irradiation (TBI) treatment and mtDNA alterations in vivo, however, has not been postulated yet. The aim of this study is to analyze mtDNA alterations in irradiated human peripheral lymphocytes from acute lymphoblastic leukemia (ALL) patients as well as to take them as predictors for radiatio...

  11. Pathologic rupture of the spleen in a patient with acute myelogenous leukemia and leukostasis

    2014-07-01

    Full Text Available Rupture of the spleen can be classified as spontaneous, traumatic, or pathologic. Pathologic rupture has been reported in infectious diseases such as infectious mononucleosis, and hematologic malignancies such as acute and chronic leukemias. Splenomegaly is considered the most relevant factor that predisposes to splenic rupture. A 66-year-old man with acute myeloid leukemia evolved from an unclassified myeloproliferative neoplasm, complaining of fatigue and mild upper left abdominal pain. He was pale and presented fever and tachypnea. Laboratory analyses showed hemoglobin 8.3 g/dL, white blood cell count 278 × 109/L, platelet count 367 × 109/L, activated partial thromboplastin time (aPTT ratio 2.10, and international normalized ratio (INR 1.60. A blood smear showed 62% of myeloblasts. The immunophenotype of the blasts was positive for CD117, HLA-DR, CD13, CD56, CD64, CD11c and CD14. Lactate dehydrogenase was 2384 U/L and creatinine 2.4 mg/dL (normal range: 0.7-1.6 mg/dL. Two sessions of leukapheresis were performed. At the end of the second session, the patient presented hemodynamic instability that culminated in circulatory shock and death. The post-mortem examination revealed infiltration of the vessels of the lungs, heart, and liver, and massive infiltration of the spleen by leukemic blasts. Blood volume in the peritoneal cavity was 500 mL. Acute leukemia is a rare cause of splenic rupture. Male gender, old age and splenomegaly are factors associated with this condition. As the patient had leukostasis, we hypothesize that this, associated with other factors such as lung and heart leukemic infiltration, had a role in inducing splenic rupture. Finally, we do not believe that leukapheresis in itself contributed to splenic rupture, as it is essentially atraumatic.

    2016-09-01

    The combination of daunorubicin and cytarabine is the cornerstone of induction therapy for acute myeloid leukemia (AML). Little data are available on the optimal chemotherapy regimen for patients with AML and advanced renal failure, with some authors recommending administration of reduced daunorubicin doses. We report the case of a 54-year-old AML patient on chronic hemodialysis who was treated with a modified induction regimen with reduced-dose daunorubin. Daunorubicin levels were measured during the treatment schedule. Although daunorubicin terminal t1/2 appears to be unaffected in hemodialysis patients, the estimated 0-23 h area under the curve was comparable with that of patients receiving full-dose daunorubicin. Therefore, dose adjustment in this patient group may be prudent. PMID:27254285

  14. Secondary acute non lymphoid leukemia in patients treated for non Hodgkin's lymphoma

    The present study was undertaken to evaluate the frequency, characteristics and actual risk of secondary acute non lymphoid leukemia (s-ANLL) in 141 patients treated for non Hodgkin's lymphoma with different modalities. One hundred and twenty-four patients received chemotherapy according to PROVECIP protocol (9). Of these, 15 also received as induction treatment a local nodal irradiation and 33 an extended field radiotherapy. Seventeen out of 141 were treated by total body irradiation. Of these, 15 relapsed and received salvage chemotherapy. Sixteen of the 124 patients trated with PROVECIP also underwent different chemotherapeutic programs as salvage treatment. Of the entire population studied, 2 patients significantly affected the occurrence of s-ANLL, since both leukemias occurred in patients treated with total body irradiation, given alone or followed by chemotherapy. The actuarial risk at 8 years was 5.24% in the whole group, whereas it greatly increased in the group of patients treated with total body irradiation (24%). Conversely, no risk was found in the group treated with PROVECIP, alone, with additional chemotherapy, or with associated local or extended field radiotherapy

  15. Mixed Pulmonary Infection with Penicillium notatum and Pneumocystis jiroveci in a Patient with Acute Myeloid Leukemia

    Tehrani, Shabnam; Hemmatian, Marjan

    2016-01-01

    Penicillium notatum is a fungus that widely exists in the environment and is often non-pathogenic to humans. However, in immunocompromised hosts it may be recognized as a cause of systemic mycosis. A 44-year-old man with acute myeloid leukemia (AML) was admitted to our hospital with fever and neutropenia. Due to no improvement after initial treatment, he underwent bronchoscopy. The patient was found to have P. notatum and Pneumocystis jiroveci infection, and therefore was given voriconazole, primaquine and clindamycin. The patient was successfully treated and suffered no complications. Conclusion: This case highlights P. notatum as a cause of infection in immunocompromised patients. To the best of our knowledge, mixed lung infection with P. notatum and P. jiroveci in a patient with AML has not been previously reported.

    2016-01-01

    Philadelphia chromosome positive (Ph+) mixed phenotype acute leukemia (MPAL) is a rare type of acute leukemia having both myeloid and lymphoid features for which no optimal treatment has yet been established. We herein describe two elderly Ph+MPAL patients who achieved molecular remission without any serious adverse events by treatment with dasatinib and prednisolone. Although dasatinib induction therapy combined with prednisolone is known to be a highly effective treatment for Ph+ acute lymphoblastic leukemia, its efficacy for Ph+MPAL has not been shown. The clinical courses of the present cases suggest that combination therapy with dasatinib and prednisolone is a safe and effective therapeutic modality in elderly Ph+MPAL patients. PMID:27150875

  20. Novel management options for adult patients with progressive acute lymphoblastic leukemia: introduction.

    Wang, Eunice S

    2015-06-01

    Acute lymphoblastic leukemia (ALL) is a heterogeneous hematologic malignancy characterized by highly proliferative immature lymphoid cells in the bone marrow and peripheral blood. In adults, ALL accounts for approximately 20% of all adult leukemias. ALL carries a poor prognosis in adults. The 5-year overall survival is 24% in patients ages 40 to 59 years and 18% in patients ages 60 to 69 years. ALL can be grouped into different categories according to its cell lineage (B cell or T cell), the presence or absence of the Philadelphia chromosome, and various cytogenetic and molecular classifications. A main goal of treatment is to allow the patient to achieve a complete remission and to consolidate this remission with either a maintenance regimen or an allogeneic stem cell transplant. Although the overall rate of complete remission following frontline therapy for newly diagnosed ALL is high, the majority of patients experience a disease relapse. In general, the duration of initial complete remission impacts the patient’s prognosis and response to further therapies. Subsequent treatments must balance the goal of achieving a remission with the need for the patient to maintain or improve quality of life. Recently approved agents, such as blinatumomab and vincristine sulfate liposome injection, offer the promise of a second remission that can serve as a bridge to allogeneic stem cell transplant while still maintaining quality of life. A novel approach using adoptive cellular immunotherapy with chimeric antigen receptor (CAR) T cells is associated with extremely robust responses. PMID:26431322

  1. Reduced-intensity conditioning allogeneic hematopoietic-cell transplantation for older patients with acute myeloid leukemia.

    Goyal, Gaurav; Gundabolu, Krishna; Vallabhajosyula, Saraschandra; Silberstein, Peter T; Bhatt, Vijaya Raj

    2016-06-01

    Elderly patients (>60 years) with acute myeloid leukemia have a poor prognosis with a chemotherapy-alone approach. Allogeneic hematopoietic-cell transplantation (HCT) can improve overall survival (OS). However, myeloablative regimens can have unacceptably high transplant-related mortality (TRM) in an unselected group of older patients. Reduced-intensity conditioning (RIC) or nonmyeloablative (NMA) conditioning regimens preserve the graft-versus-leukemia effects but reduce TRM. NMA regimens result in minimal cytopenia and may not require stem cell support for restoring hematopoiesis. RIC regimens, intermediate in intensity between NMA and myeloablative regimens, can cause prolonged myelosuppresion and usually require stem cell support. A few retrospective and prospective studies suggest a possibility of lower risk of relapse with myeloablative HCT in fit older patients with lower HCT comorbidity index; however, RIC and NMA HCTs have an important role in less-fit patients and those with significant comorbidities because of lower TRM. Whether early tapering of immunosuppression, monitoring of minimal residual disease, and post-transplant maintenance therapy can improve the outcomes of RIC and NMA HCT in elderly patients will require prospective trials.

  2. Metagenomic analysis of bloodstream infections in patients with acute leukemia and therapy-induced neutropenia.

    Gyarmati, P; Kjellander, C; Aust, C; Song, Y; Öhrmalm, L; Giske, C G

    2016-01-01

    Leukemic patients are often immunocompromised due to underlying conditions, comorbidities and the effects of chemotherapy, and thus at risk for developing systemic infections. Bloodstream infection (BSI) is a severe complication in neutropenic patients, and is associated with increased mortality. BSI is routinely diagnosed with blood culture, which only detects culturable pathogens. We analyzed 27 blood samples from 9 patients with acute leukemia and suspected BSI at different time points of their antimicrobial treatment using shotgun metagenomics sequencing in order to detect unculturable and non-bacterial pathogens. Our findings confirm the presence of bacterial, fungal and viral pathogens alongside antimicrobial resistance genes. Decreased white blood cell (WBC) counts were associated with the presence of microbial DNA, and was inversely proportional to the number of sequencing reads. This study could indicate the use of high-throughput sequencing for personalized antimicrobial treatments in BSIs. PMID:26996149

  3. Prognostic Significance of the Lymphoblastic Leukemia-Derived Sequence 1 (LYL1 Gene Expression in Egyptian Patients with Acute Myeloid Leukemia

    2014-06-01

    Full Text Available OBJECTIVE: Aberrant activation of transcription factor genes is the most frequent target of genetic alteration in lymphoid malignancies. The lymphoblastic leukemia-derived sequence 1 (LYL1 gene, which encodes a basic helix-loop helix, was first identified with human T-cell acute leukemia. Recent studies suggest its involvement in myeloid malignancies. We aimed to study the expression percent of oncogene LYL1 in primary and secondary high-risk myeloid leukemia and the impact on prognostic significance in those patients. METHODS: Using quantitative real-time polymerase chain reaction for detection of LYL1 oncogenes, our study was carried out on 39 myeloid leukemia patients including de novo cases, myelodysplastic syndrome (MDS with transformation, and chronic myelogenous leukemia (CML in accelerated and blast crisis, in addition to 10 healthy individuals as the reference control. RESULTS: LYL1 expression was increased at least 2 times compared to the controls. The highest expression of this transcription factor was observed in the MDS cases transformed to acute leukemia at 7.3±3.1, p=0.0011. LYL1 expression was found in 68.2%, 75%, and 77.8% of cases of acute myeloid leukemia, CML crisis, and MDS, respectively. Significant correlation of LYL1 overexpression with some subtypes of French-American-British classification was found. There was, for the first time, significant correlation between the blood count at diagnosis and LYL1 expression (p=0.023, 0.002, and 0.031 for white blood cells, hemoglobin, and platelets, respectively. The rate of complete remission was lower with very high levels of LYL1 expression and the risk of relapse increased with higher levels of LYL1 expression, suggesting an unfavorable prognosis for cases with enhanced expression. CONCLUSION: Overexpression of LYL1 is highly associated with acute myeloid leukemia and shows more expression in MDS with unfavorable prognosis in response to induction chemotherapy. These

  5. Addition of Arsenic Trioxide into Induction Regimens Could Not Accelerate Recovery of Abnormality of Coagulation and Fibrinolysis in Patients with Acute Promyelocytic Leukemia.

    Ye Zhang

    Full Text Available All-trans retinoic acid combined to anthracycline-based chemotherapy is the standard regimen of acute promyelocytic leukemia. The advent of arsenic trioxide has contributed to improve the anti-leukemic efficacy in acute promyelocytic leukemia. The objectives of the current study were to evaluate if dual induction by all-trans retinoic acid and arsenic trioxide could accelerate the recovery of abnormality of coagulation and fibrinolysis in patients with acute promyelocytic leukemia.Retrospective analysis was performed in 103 newly-diagnosed patients with acute promyelocytic leukemia. Hemostatic variables and the consumption of component blood were comparably analyzed among patients treated by different induction regimen with or without arsenic trioxide.Compared to patients with other subtypes of de novo acute myeloid leukemia, patients with acute promyelocytic leukemia had lower platelet counts and fibrinogen levels, significantly prolonged prothrombin time and elevated D-dimers (P<0.001. Acute promyelocytic leukemia patients with high or intermediate risk prognostic stratification presented lower initial fibrinogen level than that of low-risk group (P<0.05. After induction treatment, abnormal coagulation and fibrinolysis of patients with acute promyelocytic leukemia was significantly improved before day 10. The recovery of abnormal hemostatic variables (platelet, prothrombin time, fibrinogen and D-dimer was not significantly accelerated after adding arsenic trioxide in induction regimens; and the consumption of transfused component blood (platelet and plasma did not dramatically change either. Acute promyelocytic leukemia patients with high or intermediate risk prognostic stratification had higher platelet transfusion demands than that of low-risk group (P<0.05.Unexpectedly, adding arsenic trioxide could not accelerate the recovery of abnormality of coagulation and fibrinolysis in acute promyelocytic leukemia patients who received all

  6. Influence of Chemotherapy on the Lipid Peroxidation and Antioxidant Status in Patients with Acute Myeloid Leukemia

    2012-07-01

    Full Text Available Chemotherapeutic agents used in patients with cancer cause to generate the enormous amounts of free radicals associated with cell injury. In this study we assess the effects of chemotherapy regimen on oxidant/antioxidant status in patients with acute myeloid leukemia (AML. 38 newly diagnosed patients with acute myeloid leukemia were recruited in this study. All patients received cytarabine and daunorubicin as chemotherapy regimen. Plasma levels of malondialdehyde (MDA, total antioxidant status (TAS, and the levels of erythrocyte activity of superoxide dismutase (SOD and glutathione peroxidase (GPx were determined before chemotherapy and 14 days after chemotherapy with cytarabine and daunorubicin. Plasma MDA concentrations increased significantly (from 2.68±0.89 nmol/L to 3.14±1.29 nmol/L during the 14days post-chemotherapy period (P=0.04. Plasma TAS concentrations changed with chemotherapy from 1.09±0.15 mmol/L to 1.02±0.14 mmol/L with P=0.005. Erythrocyte SOD and GPX activity decreased overtime from 1157.24±543.61 U/g Hb to 984.01±419.09 U/g Hb (P=0.04 and 46.96±13.70 U/g Hb to 41.40±6.44 U/g Hb (P=0.02 respectively. We report here that there is an increase in malondialdehyde levels and a decrease in the levels of antioxidant enzymes and total antioxidant status. This suggests that chemotherapy causes these changes as a result of enormous production of reactive oxygen species in the patients with AML. Antioxidant supplementation must be approached with caution because of the probability of reduction the therapeutic efficacy of these cytotoxic drugs.

    2016-07-01

    The CLAG regimen is highly active in patients with relapsed and/or refractory acute myeloid leukemia (AML). We administered CLAG-based chemotherapy to 20 previously untreated AML patients who were poor candidates for standard induction therapy. Responding patients received further CLAG as post-remission therapy followed by additional therapy that was tailored to their AML subtype. Patients were considered poor candidates for standard therapy due to either cardiac disease, prior chemotherapy for another malignancy, prior myeloproliferative disease, or myelodysplastic syndrome that had progressed after hypomethylator therapy. Overall, thirteen patients had a complete response (CR) to the first cycle of therapy (65%), one patient had a CR without platelet recovery, and 3 patients had a partial response (PR). Two of the patients with PR converted to CR after further therapy. The median duration of response has not been reached; the mean duration of response is 36.8 months (95% CI 28.8-44.8 months). Median overall survival (including deaths from all causes) is 29.0 months (95% CI 18.0-46.0 months). Patients with de novo AML had a CR rate of 90.9% and a median overall survival of 38.5 months. CLAG-based therapy is a well-tolerated, efficacious induction strategy in previously-untreated patients with high risk AML. CLAG-based regimens should be studied in a broader group of newly diagnosed AML patients. PMID:27151544

    Bacillus cereus is an aerobic Gram-positive, spore-forming, rod-shaped bacterium that is responsible for foodborne illnesses. We report on a 15-year-old girl with B-cell acute lymphoblastic leukemia, who fell into a somnolent state after presenting with a 12-hour history of fever, muscle soreness, myalgia in both calves, sore throat, and vomiting. Fulminant septicemic syndrome caused by B. cereus was finally identified. The aim of this work is the introduction of B. cereus as a differential diagnosis of sepsis in patients with acute leukemia in induction chemotherapy, to prevent delayed treatment. PMID:23927823

  9. CCAAT/enhancer binding protein a gene expression in Egyptian patients with acute myeloid leukemia

    Background: Transcription factors play a crucial role in myeloid differentiation and lineage determination. Tumor suppressor protein C/EBPa is a key regulator of granulocytic differentiation whose functional inactivation has become a pathophysiological signature of myeloid leukemia. Given the role that CCAAT/enhancer binding protein α (C/EBP α) plays in myelopoiesis, we anticipated that their expression might be disrupted in myeloid neoplasms. Purpose: To estimate the expression of C/EBP α mRNA in patients with acute myeloid leukemia and correlate its expression with the pathogenesis of the disease. Patients and methods: Forty AML patients and 20 age and sex matched healthy controls were included in the study. Blood samples of patients and controls were analyzed for CEBP α mRNA expression by quantitative RT-real time PCR using TaqMan technology and δδct method for calculation of gene expression. Results: Twenty-nine (72.5%) patients out of the 40 showed low expression levels of CEBP α mRNA below the cutoff value with median of 0.19 (range:0-0.87). While eleven (27.5%) patients out of the 40 showed higher expression levels of CEBP α above the cutoff value with median of 1.52 (range: 1.07-2). Seven patients out of the 11 showed higher expression levels of CEBP α mRNA belong to the M3 subtype of AML harboring the t(15;17) PML-RARa translocation. Conclusion: We conclude that the majority of the AML patients analyzed, express low levels of C/EBPa mRN. However, a subset of patients represented by the M3 subtype, express higher levels of C/EBPa

  10. Immunology of infusion reactions in the treatment of patients with acute lymphoblastic leukemia.

    Asselin, Barbara

    2016-07-01

    Infusion reactions are potentially dose-limiting adverse events associated with intravenous administration of several common agents used to treat patients with acute lymphoblastic leukemia. True clinical hypersensitivity reactions are antibody-mediated and can occur only after repeated exposure to an antigen. Conversely, anaphylactoid infusion reactions are nonantibody-mediated and often occur on the initial exposure to a drug. Cytokine-release syndrome comprises a subset of nonantibody-mediated infusion reactions associated with the use of monoclonal antibodies and immune therapies. Clinical symptoms of hypersensitivity reactions and nonantibody-mediated infusion reactions heavily overlap and can be difficult to distinguish in practice. Regardless of the underlying mechanism, any infusion reaction can negatively affect treatment efficacy and patient safety. These events require prompt response, and potentially, modification of subsequent therapy. PMID:27086555

  11. Septic arthritis as the first sign of Candida tropicalis fungaemia in an acute lymphoid leukemia patient

    Vicari Perla

    2003-01-01

    Full Text Available Fungal infections caused by Candida species have increased in incidence during the past two decades in England, North America and Europe. Candidal arthritis is rare in patients who are not intravenous drug users or are who not using a prostheses. We report the case of a 24-year-old man with acute lymphoid leukemia, who developed Candida tropicalis arthritis during an aplastic period after chemotherapy. This is the eighth case described in the literature of C. tropicalis causing arthritis without intra-articular inoculation. We call attention to an unusual first sign of fungal infection: septic arthritis without intra-articular inoculation. However, this case differs from the other seven, since despite therapy a fast and lethal evolution was observed. We reviewed reported cases, incidence, risk factors, mortality and treatment of neutropenic patients with fungal infections.

    2014-03-01

    Full Text Available OBJECTIVE: This study aimed to assess the prognostic impact of Wilms tumor 1 (WT1 mutations in cytogenetically normal acute myeloid leukemia (CN-AML among Egyptian patients. METHODS: Exons 1, 2, 3, 7, 8, and 9 of WT1 were screened for mutations in samples from 82 CNAML patients out of 203 newly diagnosed AML patients, of age ranging from 21 to 74 years, using high-resolution capillary electrophoresis. RESULTS: Eleven patients out of 82 (13.41% harbored WT1 mutations. Mutations were detected in exon 7 (n=7, exon 9 (n=2, exon 8 (n=1, and exon 3 (n=1, but not in exons 1 or 2. There was no statistically significant difference between the WT1 mutants and wild types as regards age, sex, French-American-British subtypes, and the prevalence of success of induction remission therapy (p=0.966; 28.6% vs. 29.3%. Patients with WT1 mutations had overall survival lower than patients with the wild type (HR=1.38; 95% CI 4.79-6.86; p=0.004. CONCLUSION: CN-AML patients with WT1 mutations have poor clinical outcome. We recommend molecular testing for WT1 mutations in patients with CN-AML at diagnosis in order to improve risk stratification of those patients.

  16. An Adult Patient with Systemic Mastocytosis and B-Acute Lymphoblastic Leukemia

    Theodoros Iliakis

    2014-01-01

    Full Text Available Mastocytosis is a myeloproliferative neoplasm characterized by clonal expansion of abnormal mast cells, ranging from the cutaneous forms of the disease to mast cell leukemia. In a significant proportion of patients, systemic mastocytosis (SM coexists with another hematologic malignancy, termed systemic mastocytosis with an associated hematologic nonmast cell lineage disorder (SM-AHNMD. Despite the pronounced predominance of concomitant myeloid neoplasms, the much more unusual coexistence of lymphoproliferative diseases has also been reported. Imatinib mesylate (IM has a role in the treatment of SM in the absence of the KITD816V mutation. In the setting of SM-AHNMD, eradicating the nonmast cell malignant clone greatly affects prognosis. We report a case of an adult patient with SM associated with B-lineage acute lymphoblastic leukemia (B-ALL. Three cases of concurrent adult ALL and mastocytosis have been reported in the literature, one concerning SM and two concerning cutaneous mastocytosis (CM, as well as six cases of concomitant CM and ALL in children.

    Full Text Available Objective: We reviewed the clinical details and treatment outcome of children with newly diagnosed acute lymphoblastic leukemia (ALL to determine the significance of already established prognostic factors in our patients. Setting: A tertiary care hospital in Karachi, Pakistan. Study Design: This is a retrospective study. Materials and Methods: Children diagnosed with ALL were evaluated over a period of 17 years (January 1, 1989 to December 31, 2006. Data was collected by reviewing the medical records of the patients and the prognostic factors analyzed by us include age, gender, white blood cell count, central nervous system and mediastinal involvement at presentation, morphology and immunophenotype of the blast cells, and response to induction therapy. Results: There were 46 patients diagnosed during the study period and on regular follow-up. Forty five (97.8% of these were in complete remission after 28 days of induction therapy. Thirty patients (65.2% were alive and doing well at the time of study. Of these 30 patients, 26 (86.6% remained relapse free while only four (13.3% had relapsed. The remaining 16 patients (34.7% did not survive including 11 (68.7% who had a relapse. Only significant variables in terms of prognosis were age and ALL phenotype with a P value 0.04 and 0.03 respectively. Conclusion: We found that ALL is a frequent childhood hematological malignancy in our setting and is more prevalent in males and children less than ten years of age. Age and leukemia phenotype emerged as the important prognostic factors in pediatric ALL in our patients.

    Full Text Available Introduction. Acute leukemias treatment requires strong chemotherapy. Patients that develop bone marrow aplasia become immunocompromised, thus becoming liable to bacterial and fungal infections. Fungal infections caused by Candida are frequent. Hepatosplenic candidiasis (HSC is a frequent consequence of invasive candidiasis which is clinically presented with prolonged febrility unresponsive to antibiotics. Case Outline. A 53-year-old patient with acute myeloid leukemia was submitted to standard chemotherapy “3+7” regimen (daunoblastine 80 mg i.v. on days 1 to 3, cytarabine 2Ч170 mg i.v. during 7 days and achieved complete remission. However, during remission he developed febrility unresponsive to antibiotics. Computerised tomography (CT of the abdomen showed multiple hypodense lesions within the liver and spleen. Haemocultures on fungi were negative. However, seroconversion of biomarkers for invasive fungal infection (IFI (Candida and Aspergillus antigen/Ag and antibody/Ab indicated possible HSC. Only high positivity of anti-Candida IgG antibodies, positivity of mannan and CT finding we regarded sufficient for the diagnosis and antimycotic therapy. Three months of treatment with different antimycotics were necessary for complete disappearance of both clinical symptoms and CT findings. Conclusion. In patients with prolonged febrile neutropenia IFI has to be strongly suspected. If imaging techniques show multiple hypodense lesions within liver and spleen, HSC has to be taken seriously into consideration. We believe that, along with CT finding, positive laboratory Candida biomarkers (mannan and IgG antibodies should be considered sufficient for “probable HSC” and commencement of antifungal therapy, which must be long enough, i.e. until complete disappearance of clinical symptoms and CT findings are achieved.

    Full Text Available Long Su, SuJun Gao, XiaoLiang Liu, YeHui Tan, Lu Wang, Wei Li Cancer Center, The First Hospital, Jilin University, Changchun, People’s Republic of China Background: This study was aimed to explore the clinical characteristics and prognoses of acute myeloid leukemia (AML patients with CEBPA mutations. Patients and methods: Three hundred and forty-five patients with de novo AML were retrospectively analyzed with regard to CEBPA mutations, clinical characteristics, therapeutic responses, and long-term outcomes. Results: CEBPA mutations were detected in 59 patients (17.10%, with 47 cases harboring double mutations and 12 cases harboring single mutations. In those with a normal karyotype (NK, 44 cases (25.29% were detected with CEBPA mutations. The following characteristics were observed in CEBPA-mutated patients: most (66.10% of them were M1 or M2; they presented with higher peripheral white blood cell counts (23.71 [12.6, 60.02] ×109/L versus 7.34 [2.38, 26.63] ×109/L; u=4.944, P<0.001 and higher hemoglobin levels (89.64±23.05 g/L versus 75.65±23.65 g/L; t=4.156, P<0.001 than those observed in patients without the mutation; and the expression of CD7 and HLA-DR was higher, whereas that of CD34 and CD56 was lower in patients with the mutation than in those without the mutation. Compared with those without the mutation, patients with CEBPA mutations had a superior complete remission rate (75.0% versus 56.54%; χ2=6.185, P=0.013 and superior overall survival (P=0.034. Conclusion: The frequency of CEBPA mutations may be higher in Chinese patients with AML than has been reported in populations of western countries, and the presence of CEBPA mutations is an indication of favorable prognoses for these patients.

    Full Text Available Abstract The occurrence of acute promyelocytic leukemia (APL in HIV-infected patients has been reported in only five cases. Due to a very small number of reported HIV/APL patients who have been treated with different therapies with the variable outcome, the prognosis of APL in the setting of the HIV-infection is unclear. Here, we report a case of an HIV-patient who developed APL and upon treatment entered a complete remission. A 25-years old male patient was diagnosed with HIV-infection in 1996, but remained untreated. In 2004, the patient was diagnosed with primary central nervous system lymphoma. We treated the patient with antiretroviral therapy and whole-brain irradiation, resulting in complete remission of the lymphoma. In 2006, prompted by a sudden neutropenia, we carried out a set of diagnostic procedures, revealing APL. Induction therapy consisted of standard treatment with all-trans-retinoic-acid (ATRA and idarubicin. Subsequent cytological and molecular analysis of bone marrow demonstrated complete hematological and molecular remission. Due to the poor general condition, consolidation treatment with ATRA was given in March and April 2007. The last follow-up 14 months later, showed sustained molecular APL remission. In conclusion, we demonstrated that a complete molecular APL remission in an HIV-patient was achieved by using reduced-intensity treatment.

    2015-11-01

    Adult patients with mixed phenotype acute leukemia (MPAL) have a poor prognosis, and the therapeutic role of allogeneic stem cell transplantation (allo-SCT) for MPAL remains to be elucidated. Thus, we retrospectively assessed the efficacy of allo-SCT for MPAL. Eighteen patients with MPAL were identified from the transplant outcome database of Kanto Study Group for Cell Therapy (KSGCT). We also selected 215 patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) as control cohorts using an optimal matching method. The 5-yr overall survival (OS) rate of patients with MPAL was 48.1%, and patients in remission at the time of transplant showed significantly better survival than those not in remission (5-yr OS: 71.8% vs. 0%, P = 0.001). No significant differences were seen in OS when stratifying patients according to immunophenotype, cytogenetic abnormalities, or the type of induction therapy. The 5-yr OS rate of patients with MPAL was not significantly different compared with AML control patients (48.1% vs. 48.1%; P = 0.855) or ALL control patients (48.1% vs. 37.8%; P = 0.426). These results suggested that allo-SCT is an effective treatment for MPAL, especially early in the disease course, and innovative transplant approaches are warranted to improve the transplant outcome of patients with MPAL who are not in remission.

  7. Treatment of Acute Myeloid Leukemia in Elderly Patients-A Therapeutic Dilemma.

    Mamdani, Hirva; Santos, Cedric Dos; Konig, Heiko

    2016-07-01

    Older adults represent the majority of approximately 20,000 new patients diagnosed with acute myeloid leukemia (AML) in the United States each year. While the treatment goal for younger patients is to achieve a cure with intensive therapeutic protocols, including standard chemotherapy and hematopoietic stem cell transplantation, these goals are less well defined in the elderly population. This is in part due to the continuous decline in treatment outcomes with increasing age secondary to a number of patient-related and disease-specific factors, ranging from the presence of comorbid conditions to the higher frequency of adverse cytogenetic and unfavorable molecular markers. Although best supportive care, low-dose cytarabine, and epigenetic drugs represent well recognized treatment concepts, no universally accepted strategy for the management of elderly patients with AML exists. Therapeutic decisions are widely based on the patient's age, general health, the disease features, as well as the patient's personal wishes. The predicament of treating AML in the elderly population is the central theme of this review. PMID:27073039

    Full Text Available The Fms-like tyrosine kinase-3 (FLT3 is a receptor tyrosine kinase that plays a key role in cell survival, proliferation, and differentiation of hematopoietic stem cells. Mutations of FLT3 were first described in 1997 and account for the most frequent molecular mutations in acute myeloid leukemia (AML. AML patients with FLT3 internal tandem duplication (ITD mutations have poor cure rates the prognostic significance of point mutations; tyrosine kinase domain (TKD is still unclear. We analyzed the frequency of FLT3 mutations (ITD and D835 in patients with AML at diagnosis; no sufficient data currently exist regarding FLT3 mutations in Saudi AML patients. This study was aimed at evaluating the frequency of FLT3 mutations in patients with AML and its significance for prognosis. The frequency of FLT3 mutations in our study (18.56% was lower than many of the reported studies, FLT3-ITD mutations were observed in 14.4%, and FLT3-TKD in 4.1%, of 97 newly diagnosed AML patients (82 adult and 15 pediatric. Our data show significant increase of FLT3 mutations in male more than female (13 male, 5 female. Our results support the view that FLT3-ITD mutation has strong prognostic factor in AML patients and is associated with high rate of relapse, and high leucocytes and blast count at diagnosis and relapse.

    2011-04-01

    Imatinib mesylate (Imatinib) is a potent inhibitor of defined tyrosine kinases and is effectively used for the treatment of malignancies characterized by the constitutive activation of these tyrosine kinases, such as Philadelphia chromosome-positive (Ph(+)) leukemias and gastrointestinal stromal tumors. Suppressive as well as stimulating effects of this drug on T lymphocytes or dendritic cells (DC), which play a major role in immune tumor surveillance, have been reported. For this reason, we questioned whether Imatinib could also affect the phenotypic and functional properties of these subpopulations in Ph(+) acute lymphoblastic leukemia (ALL) patients on prolonged Imatinib maintenance treatment. Circulating T lymphocytes and NK cells from Imatinib-treated Ph(+) ALL patients showed a subset distribution comparable to that of healthy donors. In addition, T-cell immunomodulant cytokine production (IFN-γ, TNF-α) and proliferative responses were not impaired. A normal monocyte-derived DC differentiation and apoptotic body loading capacity was also observed in the majority of Imatinib-treated patients. In contrast, an impairment in the DC intracellular production of IL-12 was recorded, although this was not observed when normal DC were exposed in vitro to Imatinib. Finally, in vivo Imatinib treatment did not affect the T-lymphocyte proliferation and IFN-γ production induced by leukemic apoptotic body-loaded DC, underling the potential capability of these cells to generate a specific immune response against tumoral antigens. Taken together, these findings provide evidence that immunotherapeutic approaches aimed at controlling residual disease in Ph(+) ALL patients in hematologic remission are not jeopardized by the long-term administration of Imatinib.

  10. Antigen Expression on Blast Cells and Hematological Parameters at Presentation in Acute Lymphoblastic Leukemia Patients

    Objective: To analyze the expression of various antigens on the leukemic blasts and to determine the hematological parameters, in Acute Lymphoblastic Leukemia (ALL) patients at presentation. Study Design: Observational study. Place and Duration of Study: King Edward Medical University, Lahore and Hameed Latif Hospital, Lahore, from February 2013 to March 2014. Methodology: A total of 50 newly diagnosed and untreated patients of ALL were selected from Mayo Hospital and Hameed Latif Hospital. These patients included both genders and all age groups. Hemoglobin, total leukocyte count and platelet count were determined on hematology analyser-Sysmex-Kx-2I. Blast cell percentage was estimated on Giemsa stained blood smears. Immuno phenotyping was done on bone marrow samples by 5 colour flow cytometery on Beckman Counter Navious Flow cytometer. An acute leukemia panel of 23 antibodies was used. The data was entered and analyzed in SPSS version 22. Results: Of the 50 ALL patients, 36 (72 percentage) were B-ALL and 14 (28 percentage) T-ALL. There were 18 (36 percentage) children and 32 (64 percentage) adults. T-ALL included 22 percentage of the childhood and 31 percentage of the adult cases. Immuno phenotypic analysis showed that CD19, CD79a and CD20 were B-lineage specific markers whereas cCD3, CD3 and CD5 were T-lineage specific. CD10 was the most sensitive marker for B-ALL and CD7 was the most sensitive marker of T-ALL. TdT was expressed in 92 percentage B-ALL and 71 percentage T-ALL cases, CD34 in 58 percentage and 43 percentage cases and CD45 in 83 percentage and 100 percentage respectively. High leukocyte count (> 50 x 109/L) was present in 58 percentage cases. Hemoglobin was < 10 g/dl in 74 percentage patients and platelet count was below 20 x 109/Lin 12 percentage patients. Leukocyte count, hemoglobin, platelet count and blast cell percentage did not show a significant difference in the two ALL immuno types. Conclusion: The frequency of T-ALL is higher in childhood

  11. Acute Myeloid Leukemia Presenting as Acute Appendicitis

    2013-01-01

    Full Text Available Appendicitis in leukemic patients is uncommon but associated with increased mortality. Additionally, leukemic cell infiltration of the appendix is extremely rare. While appendectomy is the treatment of choice for these patients, diagnosis and management of leukemia have a greater impact on remission and survival. A 59-year-old Caucasian female was admitted to the surgical service with acute right lower quadrant pain, nausea, and anorexia. She was noted to have leukocytosis, anemia, and thrombocytopenia. Abdominal imaging demonstrated appendicitis with retroperitoneal and mesenteric lymphadenopathy for which she underwent laparoscopic appendectomy. Peripheral smear, bone marrow biopsy, and surgical pathology of the appendix demonstrated acute myeloid leukemia (AML with nonsuppurative appendicitis. In the setting of AML, prior cases described the development of appendicitis with active chemotherapy. Of these cases, less than ten patients had leukemic infiltration of the appendix, leading to leukostasis and nonsuppurative appendicitis. Acute appendicitis with leukemic infiltration as the initial manifestation of AML has only been described in two other cases in the literature with an average associated morbidity of 32.6 days. The prompt management in this case of appendicitis and AML resulted in an overall survival of 185 days.

  12. Thyroid-Like Follicular Carcinoma of the Kidney in a Young Patient with History of Pediatric Acute Lymphoblastic Leukemia

    2014-01-01

    Full Text Available Thyroid-like follicular carcinoma of the kidney (TLFCK is a rare histological variant of renal cell carcinoma not currently included in the World Health Organization classification of renal tumors. Only 24 previous cases of TLFCK have been reported to date. We report a case of TLFCK in a 19-year-old woman with history of pediatric acute lymphoblastic leukemia. This patient is the youngest with TLFCK to be reported to date and the first with history of lymphoblastic leukemia. The development of TLFCK in a young patient with history of lymphoblastic leukemia is interesting and suggests that genes involved in leukemogenesis may also be important for TLFCK pathogenesis. Recognition of TLFCK is important to distinguish it from other conditions that show thyroid-like features, as a misdiagnosis can result in adverse patient care.

  13. Outpatient care of patients with acute myeloid leukemia: Benefits, barriers, and future considerations.

    Vaughn, Jennifer E; Buckley, Sarah A; Walter, Roland B

    2016-06-01

    Patients with acute myeloid leukemia (AML) who receive intensive induction or re-induction chemotherapy with curative intent typically experience prolonged cytopenias upon completion of treatment. Due to concerns regarding infection and bleeding risk as well as significant transfusion and supportive care requirements, patients have historically remained in the hospital until blood count recovery-a period of approximately 30 days. The rising cost of AML care has prompted physicians to reconsider this practice, and a number of small studies have suggested the safety and feasibility of providing outpatient supportive care to patients following intensive AML (re-) induction therapy. Potential benefits include a significant reduction of healthcare costs, improvement in quality of life, and decreased risk of hospital-acquired infections. In this article, we will review the currently available literature regarding this practice and discuss questions to be addressed in future studies. In addition, we will consider some of the barriers that must be overcome by institutions interested in implementing an "early discharge" policy. While outpatient management of selected AML patients appears safe, careful planning is required in order to provide the necessary support, education and rapid management of serious complications that occur among this very vulnerable patient population.

    To assess the self-esteem of pediatric patients on chemotherapy for acute lymphoblastic leukemia (ALL) and psychological status of their parents.The psychological status of 178 children receiving chemotherapy for ALL and their parents was assessed using parenting stress index (PSI) to determine the degree of stress the parents are exposed to using parent's and child's domains. Self-esteem Scale was used to determine the psychological status of patients.The study revealed significant low level of self-esteem in 84.83% of patients. Their parents had significant psychological stress. PSI was significantly associated with parents' low sense of competence, negative attachment to their children, feeling of high restriction, high depression, poor relation to spouse, high social isolation variables of parent's domains. It was significantly associated with low distraction, negative parents' reinforcement, low acceptability, and high demanding variables of child's domains. Long duration of disease was the most detrimental factor among demographic data of the patients.Chemotherapy for ALL has a significant impact on the psychological status of both patients and their parents with high prevalence of low self-esteem in children and high degree of stress in their parents.

  15. Prognostic factors in acute promyelocytic leukemia: strategies to define high-risk patients.

    Testa, Ugo; Lo-Coco, Francesco

    2016-04-01

    All trans retinoic acid (ATRA) has revolutionized the therapy of acute promyelocytic leukemia (APL). Treatment of this leukemia with ATRA in combination with chemotherapy has resulted in complete remission rates >90 % and long-term remission rates above 80 %. Furthermore, the combination of ATRA and arsenic trioxide (ATO) was shown to be safe and effective in frontline treatment and, for patients with low and intermediate risk disease, possibly superior to the standard ATRA and anthracycline-based regimen. However, in spite of this tremendous progress, APL still remains associated with a high incidence of early death due to the frequent occurrence of an abrupt bleeding diathesis. This hemorrhagic syndrome more frequently develops in high-risk APL patients, currently defined as those exhibiting >10 × 10(9)/L WBC at presentation. In addition to high WBC count, other molecular and immunophenotypic features have been associated with high-risk APL. Among them, the expression in APL blasts of the stem/progenitor cell antigen CD34, the neural adhesion molecule (CD56), and the T cell antigen CD2 help to identify a subset of patients at higher risk of relapse and often the expression of these markers is associated with high WBC count. At the molecular level, the short PML/RARA isoform and FLT3-internal tandem duplication (ITD) mutations have been associated with increased relapse risk. These observations indicate that extended immunophenotypic and molecular characterization of APL at diagnosis including evaluation of CD2, CD56, and CD34 antigens and of FLT3 mutations may help to better design risk-adapted treatment in this disease.

    Patients with acute leukemia who initially survive invasive fungal disease must receive chemotherapy or go on to transplant. Many centers change subsequent chemotherapy to decrease the risk of fungal reactivation. This case-control study compared acute leukemia patients (n=28) who developed a proven or probable fungal disease and survived four weeks later, to patients who did not (n=78), and assessed the impact of fungal disease on the chemotherapy regimens, and overall and event-free survival.

  19. Hematopoietic stem cell transplantation with conditioning regimens containing melphalan in pediatric patients with acute lymphoblastic leukemia

    A multicenter comparative study was carried out to investigate the efficacy and safety of hematopoietic stem cell transplantation with conditioning regimens containing melphalan in pediatric patients with acute lymphoblastic leukemia. One hundred twenty three patients at a variety of remission stages were eligible for study participation. Eighty-nine were transplanted with allogeneic grafts and 34 patients with autologous grafts (23 cases with bone marrow and 11 cases with peripheral blood stem cells). Conditioning regimens used were as follows: melphalan and busulfan for 40 patients, melphalan, busulfan and TBI for 44 patients, other regimens for 39 patients. To accelerate engraftment G-CSF (lenograstim) was administered as a 1-hour or 24-hour drip infusion daily at 5 μg/kg from day 5 until hematological recovery. The five year disease free survival (DFS) was 63% for 42 patients at CR1, 41% for 41 patients at CR2 and 33% for 40 patients at other stages. There was no significant difference in the DFS between allogeneic-transplantation and autologous-transplantation in all disease stages. In patients at remission stage for CR1 and CR2, the 5-year DFS by conditioning regimen was 63% for regimen with melphalan and busulfan, 54% for regimen with melphalan, busulfan and TBI and 54% for regimens with melphalan and TBI. There was no significant difference in the DFS between the groups. Serious complications such as renal failure were observed in 11%, veno-occlusive disease in 9%, and interstitial pneumonia in 9%. The most dominating cause of death was relapse in the disease (48% of deaths) which was most commonly observed in autologous transplantation. Contrary to that, treatment related toxic death was the most frequent cause of deaths in allogeneic-transplantation. (author)

To accelerate engraftment G-CSF (lenograstim) was administered as a 1-hour or 24-hour drip infusion daily at 5 {mu}g/kg from day 5 until hematological recovery. The five year disease free survival (DFS) was 63% for 42 patients at CR1, 41% for 41 patients at CR2 and 33% for 40 patients at other stages. There was no significant difference in the DFS between allogeneic-transplantation and autologous-transplantation in all disease stages. In patients at remission stage for CR1 and CR2, the 5-year DFS by conditioning regimen was 63% for regimen with melphalan and busulfan, 54% for regimen with melphalan, busulfan and TBI and 54% for regimens with melphalan and TBI. There was no significant difference in the DFS between the groups. Serious complications such as renal failure were observed in 11%, veno-occlusive disease in 9%, and interstitial pneumonia in 9%. The most dominating cause of death was relapse in the disease (48% of deaths) which was most commonly observed in autologous transplantation. Contrary to that, treatment related toxic death was the most frequent cause of deaths in allogeneic-transplantation. (author)

    Although acquired uniparental disomy (aUPD) has been reported in relapse acute myeloid leukemia (AML), pretransplant aUPD involving chromosome 6 is poorly documented. Such events could be of interest because loss of heterozygosity (LOH) resulting from aUPD in leukemic cells may lead to erroneous res

    Despite improvements in the prognosis of childhood acute lymphoblastic leukemia (ALL), subgroups of patients would benefit from alternative treatment approaches. Our aim was to identify genes with DNA methylation profiles that could identify such groups. We determined the methylation levels of 1320...... ALL and gene sets that discriminated between subtypes of ALL and between ALL and controls in pairwise classification analyses. We also identified 20 individual genes with DNA methylation levels that predicted relapse of leukemia. Thus, methylation analysis should be explored as a method to improve...

  4. Patient-derived acute myeloid leukemia (AML) bone marrow cells display distinct intracellular kinase phosphorylation patterns

    Multiparametric analyses of phospho-protein activation in patients with acute myeloid leukemia (AML) offers a quantitative measure to monitor the activity of novel intracellular kinase (IK) inhibitors. As recent clinical investigation with FMS-like tyrosine-3 inhibitors demonstrated, targeting IK with selective inhibitors can have a modest clinical benefit. Because multiple IKs are active in patients with AML, multikinase inhibitors may provide the necessary inhibition profile to achieve a more sustained clinical benefit. We here describe a method of assessing the activation of several IKs by flow cytometry. In 40 different samples of patients with AML we observed hyper-activated phospho-proteins at baseline, which is modestly increased by adding stem cell factor to AML cells. Finally, AML cells had a significantly different phospho-protein profile compared with cells of the lymphocyte gate. In conclusion, our method offers a way to determine the activation status of multiple kinases in AML and hence is a reliable assay to evaluate the pharmacodynamic activity of novel multikinase inhibitors

    Full Text Available The frequency of p53 and Bcl-2 protein expression in 100 newly diagnosed and 10 relapsed acute myeloid leukemia (AML patients was analyzed by immunocytochemistry (ICC. The Kaplan-Meier method was used for univariate and multivariate statistical analysis to assess the relationship between p53, Bcl-2 and clinico-hematologic feature with respect to overall survival (OS using SPSS statistical software. No statistical significance was found in univariate analysis (P=0.60. However, when the subgroups of patients (+1, +2, +3 and +4 were compared, expression of p53 and Bcl-2 protein (1-10%, 11- 30%, 31-50% and >50% was statistically significant (P<0.05. However, in multivariate analysis, p53, immunopositivity was independently associated with a shorter overall survival (OS (P=0.038 while Bcl-2 immunopositivity was associated with longer overall survival (OS (P=0.002. Our finding shows that p53 and Bcl-2 protein overexpression is a strong indicator of response to chemotherapy and overall survival. This study reports for the first time AML in patients from Eastern India.

    Full Text Available Human Leukocyte Antigen-G (HLA-G contributes to cancer cell immune escape from host antitumor responses. The clinical relevance of HLA-G in several malignancies has been reported. However, the role of HLA-G expression and functions in Acute Myeloid Leukemia (AML is still controversial. Our group identified a subset of tolerogenic dendritic cells, DC-10 that express HLA-G and secrete IL-10. DC-10 are present in the peripheral blood and are essential in promoting and maintaining tolerance via the induction of adaptive T regulatory (Treg cells. We investigated HLA-G expression on blasts and the presence of HLA-G-expressing DC-10 and CD4+ T cells in the peripheral blood of AML patients at diagnosis. Moreover, we explored the possible influence of the 3′ untranslated region (3′UTR of HLA-G, which has been associated with HLA-G expression, on AML susceptibility. Results showed that HLA-G-expressing DC-10 and CD4+ T cells are highly represented in AML patients with HLA-G positive blasts. None of the HLA-G variation sites evaluated was associated with AML susceptibility. This is the first report describing HLA-G-expressing DC-10 and CD4+ T cells in AML patients, suggesting that they may represent a strategy by which leukemic cells escape the host’s immune system. Further studies on larger populations are required to verify our findings.

    In acute myeloid leukemia (AML), new prognostic tools are needed to assess the risk of relapse. Hematogones (HGs) are normal B-lymphocyte precursors that increase in hematological diseases and may influence remission duration in AML. HG detection was prospectively investigated in 262 AML patients to determine its prognostic value. Flow cytometric HG detection was performed in bone marrow aspiration after intensive chemotherapy at the time of hematological recovery. Patients with HGs in bone marrow samples had a significantly better relapse-free survival (RFS) and overall survival (OS) than patients without HGs (P = 0.0021, and P = 0.0016). Detectable HGs independently predicted RFS (HR = 0.61, 95%CI: 0.42 - 0.89, P = 0.012) and OS (HR = 0.59, 95%CI: 0.38 - 0.92, 0.019) controlling for age, ELN classification, the number of chemotherapy cycles to achieve CR, performance status, secondary AML and flow cytometric minimal residual disease (MRD). In intensively treated AML, individual determination of HGs could be useful to stratify the optimal risk-adapted therapeutic strategy after induction chemotherapy. Am. J.

    2012-09-01

    Full Text Available Abstract We report the successful treatment and sustained molecular remission using single agent nilotinib in a relapsed Philadelphia chromosome positive (Ph+ acute lymphoblastic leukemia patient after allogeneic hematopoietic stem cell transplantation. Compared to previously published studies, this is the first report where a patient did not receive additional chemotherapy after relapse, nor did she receive donor lymphocyte infusions. With nilotinib, the patient reverted back to normal blood counts and 100% donor reconstitution by single tandem repeat (STR chimerism analysis in the bone marrow and in peripheral blood, granulocytes, T and B-lymphocytes. This report also highlights the use of nilotinib in combination with extracorporeal photopheresis (ECP for concomitant graft-versus-host disease. Our data suggests that ECP, together with nilotinib, did not adversely affect the overall Graft-versus-leukemia (GVL effect.

    2016-04-01

    Full Text Available Objective: Detection of chromosomal translocations has an important role in diagnosis and treatment of hematological disorders. We aimed to evaluate the 46 new cases of de novo acute myeloid leukemia (AML patients for common translocations and to assess the effect of geographic and ethnic differences on their frequencies. Materials and Methods: In this descriptive study, reverse transcriptase-polymerase chain reaction (RT-PCR was used on 46 fresh bone marrow or peripheral blood samples to detect translocations t (8; 21, t (15; 17, t (9; 11 and inv (16. Patients were classified using the French-American-British (FAB criteria in to eight sub-groups (M0-M7. Immunophenotyping and biochemical test results of patients were compared with RT-PCR results. Results: Our patients were relatively young with a mean age of 44 years. AML was relatively predominant in female patients (54.3% and most of patients belonged to AML-M2. Translocation t (8; 21 had the highest frequency (13% and t (15; 17 with 2.7% incidence was the second most frequent. CD19 as an immunophenotypic marker was at a relatively high frequency (50% in cases with t (8; 21, and patients with this translocation had a specific immunophenotypic pattern of complete expression of CD45, CD38, CD34, CD33 and HLA-DR. Conclusion: Similarities and differences of results in Iran with different parts of the world can be explained with ethnic and geographic factors in characterizations of AML. Recognition of these factors especially in other comprehensive studies may aid better diagnosis and management of this disease.

  14. "HLA Class II Allele and Haplotype Frequencies in Iranian Patients with Acute Myelogenous Leukemia and Control Group "

    Abdolfattah Sarafnejad

    2006-09-01

    Full Text Available Previous studies have demonstrated some significant differences in HLA allele frequencies in leukemic patients and normal subjects. We have analyzed HLA class II alleles and haplotypes in 60 Iranian patients with acute myelogenous leukemia (AML and 180 unrelated normal subjects. Blood samples were collected after obtaining informed consents. From the patients and control DNA extraction and HLA typing were performed using PCR-SSP method. Significant positive association with the disease was found for HLA-DRB1*11 allele (35% vs. 24.7%, p=0.033. Two alleles including HLA-DRB4 and –DQB1*0303 were found to be significantly decreased in patients compared to controls. Regarding haplotype analysis, no significant association was found between case and control groups. It is suggested that HLA-DRB1*11 allele plays as a presumptive predisposing factor while the HLA-DRB4 and –DQB1*0303 alleles are suggested as protective genetic factors against acute myelogenous leukemia. Larger studies are needed to confirm and establish the role of these associations with acute myelogenous leukemia.

    ENMD-2076 is a novel, orally-active molecule that inhibits Aurora A kinase, as well as c-Kit, FLT3 and VEGFR2. A phase I study was conducted to determine the maximum tolerated dose (MTD), recommended phase 2 dose (RP2D) and toxicities of ENMD-2076 in patients with acute myeloid leukemia (AML) and chronic myelomonocytic leukemia (CMML). Patients received escalating doses of ENMD-2076 administered orally daily [225 mg (n = 7), 375 mg (n = 6), 325 mg (n = 9), or 275 mg (n = 5)]. Twenty-seven patients were treated (26 AML; 1 CMML-2). The most common non-hematological toxicities of any grade, regardless of association with drug, were fatigue, diarrhea, dysphonia, dyspnea, hypertension, constipation, and abdominal pain. Dose-limiting toxicities (DLTs) consisted of grade 3 fatigue, grade 3 typhilitis, grade 3 syncope and grade 3 QTc prolongation). Of the 16 evaluable patients, one patient achieved a complete remission with incomplete count recovery (CRi), three experienced a morphologic leukemia-free state (MLFS) with a major hematologic improvement in platelets (HI-P), and 5 other patients had a reduction in marrow blast percentage (i.e. 11-65 %). The RP2D in this patient population is 225 mg orally once daily. PMID:27406088

    Full Text Available Abstract Background Mitochondrial DNA (mtDNA alterations, including mtDNA copy number and mtDNA 4977 bp common deletion (CD, are key indicators of irradiation-induced damage. The relationship between total body irradiation (TBI treatment and mtDNA alterations in vivo, however, has not been postulated yet. The aim of this study is to analyze mtDNA alterations in irradiated human peripheral lymphocytes from acute lymphoblastic leukemia (ALL patients as well as to take them as predictors for radiation toxicity. Methods Peripheral blood lymphocytes were isolated from 26 ALL patients 24 hours after TBI preconditioning (4.5 and 9 Gy, respectively. Extracted DNA was analyzed by real-time PCR method. Results Average 2.31 times mtDNA and 0.53 fold CD levels were observed after 4.5 Gy exposure compared to their basal levels. 9 Gy TBI produced a greater response of both mtDNA and CD levels than 4.5 Gy. Significant inverse correlation was found between mtDNA content and CD level at 4.5 and 9 Gy (P = 0.037 and 0.048. Moreover, mtDNA content of lymphocytes without irradiation was found to be correlated to age. Conclusions mtDNA and CD content may be considered as predictive factors to radiation toxicity.

    2013-05-01

    Full Text Available Background: Adipose tissue secretes a large number of adipocytokines such as leptin, resistin, and adiponectin. Many of these hormones and cytokines are altered in obese individuals and may lead to disruption of the normal balance between cell proliferation, differentiation, and apoptosis. The aim of our work was to investigate the disturbance of secretion of adiponectin and resistin in de novo and relapsed acute lymphoblastic leukemia (ALL in Egyptian children and determine whether adiponectin and resistin are implicated in increased risk relapse compared to healthy individuals.Methods: Measurements of adiponectin and resistin were performed at diagnosis, in 32 patients with de novo ALL aged 3 to 18 years (mean 9.8 y and 19 children with relapsed ALL aged 5 to 17 (mean 9.9 yr. 10 apparently healthy children with matched age and sex were used as controls.Results: Mean adiponectin levels were low (P < 0.05, whereas mean resistin levels were high (P<0.05 at diagnosis and relapsed ALL (compared to healthy controls. A significant decrease of adiponectin levels was observed in relapsed ALL compared to de novo ALL. In contrast resistin was significantly increased in relapsed ALL compared to de novo patients. Adiponectin in ALL subjects inversely correlated with resistin level (r = -0.51, P < 0.001.Conclusion: Low adiponectin and high resistin level at diagnosis suggest their implication in ALL pathogenesis and may serve as potential clinically significant diagnostic markers to detect leukemic relapse.

    The cytogenetic and molecular data is recognized as the most valuable prognostic factor in acute myeloid leukemia (AML). Our aim was to systemically analyze the cytogenetics of Korean AML patients and to compare the cytogenetic profiles of various races to identify possible geographic heterogeneity. We retrospectively reviewed medical records of 2806 AML patients diagnosed at 11 tertiary teaching hospitals in Korea between January 2007 and December 2011. The most common recurrent chromosomal abnormality was t(8;21) (8.8 %, 238/2717), but t(15;17) showed an almost same number (8.6 %,235/2717). Among de novo AML, the most frequent aberrations were t(15;17), observed in 229 (10.7 %). The most common French-American-British (FAB) classification type was M2 (32.2 %), and recurrent cytogenetic abnormalities correlated with the FAB subtypes. Among 283 secondary AML cases, myelodysplastic syndrome was the most common predisposing factor. About 67.1 % of the secondary AML cases were associated with chromosomal aberrations, and chromosome 7 abnormalities (n = 45, 15.9 %) were most common. The incidence of FLT3 internal tandem duplication mutation was relatively low at 15 %. Our study reports certain similarities and differences in comparison to previous reports. Such discrepancies call for extensive epidemiological studies to clarify the role of genetic as well as geographic heterogeneity in the pathogenesis of AML. PMID:27230620

    Full Text Available Background: Acute lymphoblastic leukemia (ALL is the sixth most common malignancy in Iran. Cytogenetic analysis of leukemic blasts plays an important role in classification and prognosis in ALL patients. The purpose of this study was to define the frequency of chromosomal abnormalities of ALL patients in adults and children in Fars province, Iran. Methods: In this cross-sectional study, we evaluated karyotype results of bone marrow specimens in 168 Iranian patients with ALL (154 B-ALL and 14 T-ALL in Fars Province using the conventional cytogenetic G-banding method. Results: The frequency of cytogenetic abnormalities, including numerical and/or structural changes, was 61.7% and 53.8% in the B-ALL and T-ALL patients, respectively. Hyperdiploidy was the most common (32% cytogenetic abnormality. Among structural abnormalities, the most common was t(9;22 in 11% of the patients. The children showed a higher incidence of hyperdiploidy and lower incidence of t(9;22 than adults (P<0.05. We found a lower incidence of recurrent abnormalities such as 11q23, t(1;19, and t(12;21 than those reported in previous studies. Conclusion: Normal karyotype was more frequent in our study. The frequencies of some cytogenetic abnormalities such as hyperdiploidy and t(9;22 in our study were comparable to those reported in the literature. The results of this study in Fars Province can be used as baseline information for treatment decision and research purposes in ALL patients. We recommend the use of advanced molecular techniques in the future to better elucidate cryptic cytogenetic abnormalities.

    Acute leukemias are characterized by accumulation of immature cells (blasts) and reduced production of healthy hematopoietic elements. According to the lineage origin, two major leukemias can be distinguished: acute myeloid leukemia (AML) and acute lymphoid leukemia (ALL). Although the survival rate for pediatric ALL is close to 90%, half of the young adults with AML or ALL and approximately 90% of older patients with AML or ALL still die of their disease, raising the need for innovative therapeutic approaches. As almost all leukemic blasts express specific surface antigens, targeted immunotherapy appears to be particularly promising. However, published results of immunotherapy alone are generally modest. Radioimmunotherapy (RIT) brings additional therapeutic mechanisms using radiolabeled monoclonal antibodies (mAbs) directed to tumor antigens, thus adding radiobiological cytotoxicity to immunologic cytotoxicity. Because of the high radiosensitivity of tumor cells and the diffuse widespread nature of the disease, making it rapidly accessible to circulating radiolabeled mAbs, acute leukemias represent relevant indications for RIT. With the development of recombinant and humanized mAbs, innovative radionuclides, and more efficient radiolabeling and pretargeting techniques, RIT has significantly improved over the last 10 years. Different approaches of α and β RIT targeting CD22, CD33, CD45, or CD66 antigens have already been evaluated or are currently being developed in the treatment of acute leukemia. This review summarizes the preclinical and clinical studies demonstrating the potential of RIT in treatment of AML and ALL. PMID:26897718

    Cytomegalovirus (CMV)-reactivation is associated with graft-vs-leukemia (GVL) effect by stimulating natural-killer or T-cells, which showed leukemia relapse prevention after hematopoietic stem cell transplantation (HSCT). We enrolled patients with acute myeloid leukemia (n = 197) and acute lymphoid leukemia (n = 192) who underwent allogeneic-HSCT in first remission. We measured RQ-PCR weekly to detect CMV-reactivation and preemptively used ganciclovir (GCV) when the titer increased twice consecutively, but GCV was sometimes delayed in patients without significant graft-vs-host disease (GVHD) by reducing immunosuppressive agents. In the entire group, CMV-reactivation showed poor overall survival (OS). To evaluate subsequent effects of CMV-reactivation, we excluded early relapse and deaths within 100 days, during which most of the CMV-reactivation occurred. Untreated CMV-reactivated group (n = 173) showed superior OS (83.8% vs. 61.7% vs. 74.0%, p acute leukemia. PMID:26883100

    2016-01-01

    Introduction Acute myeloid leukemia (AML) is a genetically heterogeneous disease at both the cytogenetic and molecular levels. In AML cells many chromosomal aberrations are observed, some of them being characteristic of a particular subtype of patients, and others being less significant. Besides chromosomal abnormalities, the leukemic cells can have a variety of mutations involving individual genes. The aim of this work was to investigate the frequencies of molecular alterations with the focu...

    We evaluated whether clofarabine-containing chemotherapy predisposed patients to hepatic toxicity (particularly venoocclusive disease [VOD]) after allogeneic stem cell transplantation (allo-SCT). In the group who received clofarabine and subsequent transplantation, there were no cases of VOD, and liver toxicity was comparable to a control group who received standard acute myeloid leukemia (AML) chemotherapy. Other transplant-specific outcomes, including overall survival (OS), were also simila...

    Aoki, Sadao; Nomoto, Nobuhiko; Maruyama, Souichi; Shinada, Shoji; Shibata, Akira

    1991-01-01

    Phenotypes of leukemic cells can be determined through dual staining with pairs of FITC-labeled and PE-labeled monoclonal antibodies using a laser flow cytometer. Hybrid acute leukemia (HAL) was diagnosed when leukemic cells expressed 2 or more lymphoid markers and at least on myeloid marker simultaneously. Based on this criteria, nineteen out of 72 cases with untreated acute leukemia were diagnosed as HAL, 15 of 29 (51%) patients with acute lymphoblastic leukemia and 4 of 43 (9%) patients wi...

    Acute myeloid leukemia patients with complex karyotype (CK-AML) account for approximately 10-15% of adult AML cases, and are often associated with a poor prognosis. Except for about 70% of CK-AML patients with biallelic inactivation of TP53, the leukemogenic mechanism in the nearly 30% of CK-AML patients with wild-type TP53 has remained elusive. In this study, 15 cases with complex karyotype and wild-type TP53 were screened out of 140 de novo AML patients and the expression levels of MDM4, a ...

    Background and purpose: The purpose of this prospective study was to evaluate the hypothesis that magnetization transfer ratio (MTR) histogram analysis of the whole brain could detect early and subtle brain changes nonapparent on conventional magnetic resonance imaging (MRI) in children with acute lymphoblastic leukemia (ALL) receiving methotrexate (MTX) therapy. Materials and methods: Subjects in this prospective study comprised 10 children with ALL (mean age, 6 years; range, 0-16 years). In addition to conventional MRI, magnetization transfer images were obtained before and after intrathecal and intravenous MTX therapy. MTR values were calculated and plotted as a histogram, and peak height and location were calculated. Differences in peak height and location between pre- and post-MTX therapy scans were statistically analyzed. Conventional MRI was evaluated for abnormal signal area in white matter. Results: MTR peak height was significantly lower on post-MTX therapy scans than on pre-MTX therapy scans (p = 0.002). No significant differences in peak location were identified between pre- and post-chemotherapy imaging. No abnormal signals were noted in white matter on either pre- or post-MTX therapy conventional MRI. Conclusions: This study demonstrates that MTR histogram analysis allows better detection of early and subtle brain changes in ALL patients who receive MTX therapy than conventional MRI.

  14. Successful voriconazole treatment of invasive pulmonary aspergillosis in a patient with acute biphenotypic leukemia

    Hirano,Teiichi

    2009-08-01

    Full Text Available A 23-year old woman with acute biphenotypic leukemia (ABL complained of chest pain with cough, high fever and hemoptysis during induction chemotherapy, although she had been treated with anti-biotics and micafungin. We made a clinical diagnosis of invasive pulmonary aspergillosis (IPA based on a consolidation in the right upper lung field on a chest radiograph as well as a high level of serum beta-D-glucan (with no evidence of tuberculosis and candidiasis. We changed her treatment from micafungin to voriconazole. Later, we discovered an air-crescent sign by CT scan that supported the diagnosis of IPA. Following voriconazole treatment, clinical symptoms ceased and abnormal chest shadows improved gradually and concurrently with a recovery of neutrophils. IPA must be considered in immunocompromised patients with pulmonary infiltrates who do not respond to broad-spectrum antibiotics. Serological tests and CT findings can aid in early diagnosis of IPA, which, along with treatment for IPA, will improve clinical outcomes.

  15. The prognostic significance of minimal residual disease in adult Egyptian patients with precursor acute lymphoblastic leukemia

    Background: Minimal residual disease (MRD) studies in adult acute lymphoblastic leukemia (ALL) give highly significant prognostic information superior to other standard criteria as Minimal residual disease; age, gender and total leucocytic count (TLC) in distinguishing patients at high and low risk of Flow cytometry relapse. Objectives: We aimed to determine the value of MRD monitoring by flow cytometry (FCM) in predicting outcome in adult Precursor ALL patients. Patients and methods: Bone marrow (BM) samples were analyzed by 4-color FCM collected at diagnosis and after induction therapy (MRD1) to correlate MRD positivity with disease free survival (DFS) and overall survival (OS). Results: Study included 57 adult ALL patients (44 males and 13 females) with a median age of 22 years (18-49). DFS showed no significant difference with age, gender and initial TLC (p = 0.838, 0.888 and 0.743, respectively). Cumulative DFS at 2 years was 34% for B-lineage ALL (n: 35) and 57% for T-lineage ALL (n: 18) (p = 0.057). Cumulative DFS at 2 years was M.A. Samra et al. 136 7% for MRD1 positive (high risk, HR) versus 57% for MRD1 negative patients (Low risk, LR) (p < 0.001). Cumulative DFS at 2 years was 29% for HR patients (n: 26) versus 55% for LR (n: 27) according to GMALL classification (p = 0.064). Cumulative OS did not differ according to age, gender and TLC (p = 0.526, 0.594 and 0.513, respectively). Cumulative OS at 2 years was 36% for B ALL (n: 39) versus 77% for TALL (n: 18) (p = 0.016) and was 49% for Philadelphia chromosome (Ph) negative patients versus 0% for Ph-positive patients (p < 0.001). Regarding MRD1, OS at 2 years was 18% for MRD1 HR (n:17) versus 65% for MRD1 LR (n: 38) (p < 0.001). OS was 35% for high-risk patients (n: 30) and 62% for low-risk patients (n: 27) classified according to GMALL risk stratification (p = 0.017). Conclusion: MRD by FCM is a strong independent predictor of outcome in terms of DFS and OS and is a powerful informative parameter in

    Full Text Available Breast involvement by leukemic infiltration is usually bilateral, but may be unilateral. Clinically patients can present with either single or multiple masses, or with diffuse breast engorgement, with or without nodularity. The affected patients are predominantly young adults. We present a case of an adolescent girl with acute myeloid leukemia having bilateral breast infiltration by leukemic cells.

  1. Acute childhood leukemia: Nursing care

    Modern therapy for childhood acute leukemia has provided a dramatically improved prognosis over that of just 30 years ago. In the early 1960's survival rates for acute lymphocytic leukemia (ALL) and acute myelogenous leukemia (AML) were 4% and 3%, respectively. By the 1980's survival rates had risen to 72% for all and 25% to 40% for AML. Today, a diagnosis of all carries an 80% survival rate and as high as a 90% survival rate for some low-risk subtypes. Such high cure rates depend on intense and complex, multimodal therapeutic protocols. Therefore, nursing care of the child with acute leukemia must meet the demands of complicated medical therapies and balance those with the needs of a sick child and their concerned family. An understanding of disease process and principles of medical management guide appropriate and effective nursing interventions. Leukemia is a malignant disorder of the blood and blood- forming organs (bone marrow, lymph nodes and spleen). Most believe that acute leukemia results from a malignant transformation of a single early haematopoietic stem cell that is capable of indefinite self-renewal. These immature cells of blasts do not respond to normal physiologic stimuli for differentiation and gradually become the predominant cell in the bone marrow

    2016-01-01

    Background Decreased physical performance and impaired physiological and psychological fitness have been reported in patients with acute leukemia (AL). We performed a meta-analysis to assess the efficacy of exercise in patients with AL. Methods In this meta-analysis, the electronic databases MEDLINE, Embase, Cochrane, Web of Science, SPORTDiscus, CINAHL and PEDro were searched through November 2015. Three authors participated in the study selection, data extraction and quality assessment. The instrument used for quality assessment was derived from the Cochrane Handbook for Systematic Reviews of Interventions. Analyses were performed according to the recommendations of The Cochrane Collaboration using Review Manager 5.3. Results Nine trials (8 randomized controlled trials and 1 quasi-experimental design trial) with 314 AL participants were included in this meta-analysis. The pooled standardized mean differences between the exercise and control groups were 0.45 (95% confidence interval (CI): 0.09 to 0.80, P value = 0.01, P for heterogeneity = 0.23, I2 = 28%) for cardiorespiratory fitness and 0.67 (95% CI: 0.28 to 1.06, P value = 0.0007, P for heterogeneity = 0.14, I2 = 43%) for muscle strength. Based on the data for fatigue, anxiety, and depression, there were no significant differences in these parameters between the exercise and control groups. Conclusions Exercise has beneficial effects on cardiorespiratory fitness, muscle strength and functional mobility; however, no significant improvements in fatigue, anxiety, depression or quality of life were observed. Further large-scale randomized trials are needed to assess the safety, feasibility and efficacy of exercise programs for AL patients. PMID:27463234

  6. Molecular Detection of BCR/ ABL Fusion Gene in Saudi Acute Lymphoblastic Leukemia Patients

    Background: Molecular cytogenetics is becoming one of the most useful tools targeting some genes which are generally considered to lead to leukemic transformation (as well as for numerical abnormalities). A fraction of acute lymphoblastic leukemia (ALL) cases carry the translocation t(9;22) (q34;ql1.2) which juxtaposes the ABL proto-oncogene to the BCR gene generating a chimeric gene, BCR/ABL. This aberration is more frequent in adult ALL (20%-40%) than in pediatric ALL >)5%), and predicts poor clinical outcome. Aim of our Work: Is to study BCR/ A BL fusion gene in ALL cases using fluorescent in situ hybridization. Patients and Methods: Twenty newly diagnosed ALL patients, 16 adult and 4 paediatric cases, were included in the study, 11 cases (55%) were of precursor B phenotype, S cases (40%) belonged to T lineage, while one case was bi phenotypic expressing mainly precursor B cell markers tether with CD13, CD33, CD117, Detection of BCR/ABL fusion gene was done using interphase FISH technique and was confirmed molecularly using the RT-PCR technique. Results: BCR/ ABL fusion gene was negative in all the examined cases, yet abnormality involving 9q34, ABL gene, either by addition or deletion was detected in three cases (15%). Two of these cases were associated with BCR gene extra copies (three and four copies, respectively). Conclusion: This may reflect the frequency of association of ABL gene and BCR gene abnormality in our cases, and that absence of fusion gene BCR/ABL does not exclude their role in the leukomogenic process, yet a larger study is required to confirm and detect the prevalence of these gene disturbances in ALL and their association

  7. Frank hematuria as the presentation feature of acute leukemia

    2010-01-01

    Full Text Available Muco-cutaneous bleeding is a common presenting feature of acute leukemias. Mucosal bleeding usually manifests as gum bleeding and/or epistaxis but may occur in any mucosal surface of the body. Hematuria as an isolated or main presenting feature of acute leukemia is rare. We describe two cases of acute leukemia, a 19 year old male with acute lymphoblastic leukemia and a 52 year old male with acute myeloid leukemia, both presenting with gross hematuria. There was no demonstrable leukemic infiltration of the urinary tract on imaging studies. Hematuria in these patients was likely to be due to occult leukemic infiltration of the urinary system, aggravated by thrombocytopenia, as it subsided after starting chemotherapy. Our cases highlight that hematuria should be remembered as a rare presenting feature of acute leukemia.

  8. P-GLYCOPROTEIN QUANTITATION IN ACUTE LEUKEMIA

    Mali in Nikougoftar

    2003-06-01

    Full Text Available Multi drug resistance(MDR is a major problem in the treatment of cancer and hemalological malignancies. This resistance is multi factorial and is the result of decreased intra cellular drug accumulation. This is partly due to the presence of a 170KD intra membranous protein termed P-glycoprotein(P-gp that is an energy-dependent efflux pump which has increased expression on drug-resistance cells. In this study we identified the presence of P-gp by staining with Fluorescent Iso Thio Cyanate (FITC conjugated anti P-gp in acute leukemia patients and flow cytometry in addition to performing immunophenotype analysis and French, American British (FAB classification. Results revealed that one fifth of leuke¬mic patients expressed P-gp and this phenotype was more prevalent in Acute Undifferentiated Leukemia(AUL and Acute Myelogenous Leukemia (AML than in Acute Lymphoblastic Leukemia(ALL. Other findings showed a logical rela¬tionship between this phenotype and age groups. There was not any association between P-gp+ phenotype and FAB and Immunophenotyping sub classification, but there was a linear relationship between CD34 and CD7 expression and P-gp+ phenotype. The accumulation of P-gp molecule that was stated as Mean Fluores¬cence Intensity (MFI on the blasts1 membrane of AUL and AML patients showed marked increase in comparison to ALL. Furthermore MFI in P-gp+ relapsed patients was much more than P-gp+ pretreatment patients.

  9. Psychological Risk Factors in Acute Leukemia

    2009-04-01

    Full Text Available Several theoretical models have been occasionally proposed to account for the involvement of psychological factors in cancer genesis. Family environment and relations as well as certain personality traits were correlated to cancer onset. However, little is known in the case of acute leukemia. The present study examined family environment, state-trait anxiety, hostility and the direction of hostility as well as alexithymia in 41 acute leukemia patients and their first degree relatives (70. In accordance with previous findings, the present results showed that family cohesion, conflict and organization as well as guilt, state anxiety and alexithymia were significant risk factors for the development of the disease.

    Objective: Aberrant activation of transcription factor genes is the most frequent target of genetic alteration in lymphoid malignancies. The lymphoblastic leukemia-derived sequence 1 (LYL1) gene, which encodes a basic helix-loop helix, was first identified with human T-cell acute leukemia. Recent studies suggest its involvement in myeloid malignancies. We aimed to study the expression percent of oncogene LYL1 in primary and secondary high-risk myeloid leukemia and the impact on prognostic sig...

    2003-01-01

    Objectives To investigate patients with acute lymphoblastic leukemia (ALL) for TEL/AML1 fusion, BCR/ABL fusion, MLL gene rearrangements, and numerical changes of chromosomes 4, 10, 17 and 21 by fluorescence in situ hybridization (FISH) and to determine the relationship and the significance of those findings.Methods Fifty-one American patients (34 men and 17 women) were included in this study. Of them there were 41 patients with pro-B cell type ALL, 9 with B cell type ALL and 1 with T cell type ALL. Chromosome metaphases of each sample were prepared according to standard protocols. Fluorescence in situ hybridization was performed using commercially available DNA probes, including whole chromosome painting probes, locus specific probes, specific chromosome centromere probes and dual color/multiple color translocation fusion probes. The digital image analysis was carried out using Cytovision and Quips FISH programs.Results An overall incidence of chromosomal anomalies, including t (9;22), MLL gene rearrangements, t (12;21), and numerical chromosomal anomalies of chromosomes 4, 10, 17 and 21 was found in 33 patients (65%). Thirty-one of them were pediatric patients and two adults. The t (12;21) was the commonest chromosomal anomaly detected in this population; 14 out of the 45 pediatric patients (31%) were positive for TEL/AML1 fusion, among which three had an additional derivative 21 [t (12;21)], four had a deletion of 12p and two had an extra copy of chromosome 21. All 14 patients with positive TEL/AML1 fusion had ALL pre-B cell or B-cell lineage according to standard immunotyping. The percentage of cells with fusion signals ranged from 20% to 80%. All fourteen patients positive for TEL/AML1 gene fusion were mosaic. Three out of the 14 patients positive for the TEL/AML1 gene fusion were originally reported to be culture failures and none of the remaining eleven samples had been found to have chromosome 12 abnormalities by conventional cytogenetic techniques.

  13. Nucleophosmin (NPM1) gene variants in Egyptian patients with acute myeloid leukemia

    To the editor Kassem et al. [1] described a novel mutational deletion [del 1178 (A)] in the 30 untranslated region of NPM1 gene detected in a heterozygous form in seven de novo acute myeloid leukemia (AML) patients of their study population. The described nucleotide deletion is an NPM1 gene polymorphism recorded in db SNP database (rs34351976; g28027: Genbank accession number NG016018.1) (http://www.ncbi.nlm.nih.gov/projects/SNP/) and was described previously by Do hner et al. [2] and Chou et al. [3]. This variant accounted for 60-70% of AML patients with normal karyotype [2]. The putative deletion was also identified in healthy volunteers and persisted at complete remission and also at relapse of AML patients [3]. This deletion had no effect on the predicted amino acid sequence and is not in linkage disequilibrium with any previously identified NPM1 mutations [2,3]. Analysis of RNA folding at the region surrounding the rs34351976 in the presence or absence of the deletion using Mfold analysis software (http://www.mfold.rna.albany.edu) revealed no RNA folding change that may alter RNA splicing and subsequently gene expression. Furthermore, splicing motifs analysis using Human Splicing Finder software version 2.4.1 showed that the presence of the deletion does not abolish any recognition site of exonic or intronic enhancers or silencer motifs. In general, it seems that the impact of NMP1 polymorphisms on the molecular pathogenesis of AML is not clear yet and needs further investigation. Kassem et al. [1] describes the molecular aspect of de novo AML in the Egyptian population. The previously known NPM1 mutations mentioned in their study are less frequent compared to the figures recorded worldwide. Moreover, the authors wondered whether the NPM1 variants identified in their patients may confer a better outcome of AML. According to the previously mentioned data, one can speculate that the presence of NPM1 gene polymorphism (rs34351976) should not be mistaken as being

  14. Methylation of Gene CHFR Promoter in Acute Leukemia Cells

    GONG Hui; LIU Wengli; ZHOU Jianfeng; XU Huizhen

    2005-01-01

    Summary: In order to explore whether gene CHFR was inactivated by methylation in leukemia cells, the expression of CHFR was examined before and after treatment with demethylation agent in Molt-4, Jurkat and U937 leukemia cell lines by means of RT-PCR. The methylation of promoter in Molt-4, Jurkat and U937 cells as well as 41 acute leukemia patients was analyzed by MS-PCR. The results showed that methylation of CHFR promoter was inactivated and could be reversed by treatment with a demethylating agent in Molt-4, Jurkat and U937. CHFR promoter methylation was detected in 39 % of acute leukemia patients. There was no difference in incidence of CHFR promoter methylation between acute myelocytic leukemia and acute lymphocytic leukemia. In conclusion, CHFR is frequently inactivated in acute leukemia and is a good candidate for the leukemia supper gene. By affecting mitotic checkpoint function, CHFR inactivation likely plays a key role in tumorigenesis in acute leukemia. Moreover, the methylation of gene CHFR appears to be a good index with which to predict the sensitivity of acute leukemia to microtubule inhibitors.

    2016-05-01

    We report a case of Cyberlindnera fabianii fungemia after umbilical cord blood transplantation (CBT). A 69-year-old woman was diagnosed as having mixed phenotype acute leukemia. The patient received CBT for primary refractory disease. After preconditioning chemotherapy, the patient's condition deteriorated, leading to acute respiratory failure from capillary leak syndrome and consequent admittance to the intensive care unit. The patient recovered temporarily following the administration of noninvasive positive pressure ventilation and continuous hemodiafiltration, but died of fungemia with the presence of yeast-like cells 15 days post-CBT. The yeast-like cells were analyzed by sequencing of the D1/D2 domain of the large subunit and the internal transcribed spacer domain, and were identified as C. fabianii. This case shows that molecular genetic-based methods may be effective for detecting undetermined invasive fungal infections in stem cell transplantation settings. PMID:26879198

  16. Leukemia Stem Cells and Human Acute Lymphoblastic Leukemia

    Bernt, Kathrin M.; Armstrong, Scott A.

    2009-01-01

    Leukemias and other cancers have been proposed to contain a subpopulation of cells that display characteristics of stem cells, and which maintain tumor growth. That most anti-cancer therapy is directed against the bulk of the tumor, and possibly spares the cancer stem cells, may lie at the heart of treatment failures with conventional modalities. Leukemia stem cells are fairly well described for acute myeloid leukemia (AML), but their existence and relevance for acute lymphoblastic leukemia (...

    Full Text Available The fms-like tyrosine kinase 3 (FLT3 gene is a member of the class III receptor tyrosine kinase family, mutations of FLT3 were first described in 1997 and account for the most frequent molecular mutations in acute myeloid leukemia. No data currently exist regarding FLT3 mutations in Saudi acute lymphoblastic leukemia (ALL patients as no study has reported for FLT3 mutations in Saudi ALL patients. In this retrospective study, we have examined a cohort of 77 ALL patients, to determine the prevalence of FLT3 mutations and the possible prognostic relevance of these mutations in ALL patients and did correlations to other biologic factors, such as karyotype, molecular mutations, and leukocyte count. FLT3 internal tandem duplication (ITD mutations and point mutation in tyrosine kinase domain (D835 mutations were analyzed in ALL patients at diagnosis by polymerase chain reaction (PCR. 2 cases (2.6%, 2/77 were positive for FLT3 mutations, one was found to have FLT3/ITD and other was found to have FLT3/D835. Our findings suggest that FLT3 mutations were not common in Saudi ALL and did not affect clinical outcome.

  18. Prognostic value of IDH1 mutations identified with PCR-RFLP assay in acute myeloid leukemia patients

    Background: Somatic mutations in isocitrate dehydrogenase 1 (1DH1) gene occur frequently in primary brain tumors. Recently theses mutations were demonstrated in acute myeloid leukemia (AML). So far, assessment of these mutations relied on the DNA sequencing technique. Aim of the work: The aim of this study was to detect somatic mutations in IDH1 gene using mismatched primers suitable for endonuclease based detection, without the need for DNA sequencing, and to estimate its prognostic value, on patients with de novo AML. Methods: Residual DNA extracted from pretreatment bone marrow (BM) samples of 100 patients with de novo AML was used. The polymerase chain reaction-restriction fragment length polymorphism method (PCR-RFLP) was adapted to IDHl gene, codon 132 mutations screening. Results: The frequency of IDH1 mutations was 13%. In the non-acute promyelocytic leukemia group (non-APL), IDH1 mutations were significantly associated with FLT3-ITD negative patients (p = 0.03). Patients with 1DH1 mutations did not achieve complete remission (CR). There was a trend for shorter overall survival (OS) in patients with IDH1 mutation compared to those with wild type (p = 0.08). Conclusion: IDH1 mutations are recurring genetic alterations in AML and they may have unfavorable impact on clinical outcome in adult AML. The PCR-RFLP method allows for a fast, inexpensive, and sensitive method for the detection of IDF11 mutations in AML.

    This randomized-controlled trial studied the efficacy of palifermin, administered as a dose during hematopoietic stem cell transplant (HSCT) therapy, as primary prophylaxis on pediatric patients with acute lymphoblastic leukemia in order to reduce oral mucositis (OM). Patients in the palifermin group were randomly assigned to receive palifermin, 60 μg/kg, intravenously as a single dose 3 days before and 0, +1, and +2 post autologous HSCT infusion. The patients in the control group received only a placebo treatment. OM-related assessments were the WHO oral-toxicity scale and the patient-reported outcomes. There was a statistically significant reduction in the incidence of OM grade 3 and 4 in the palifermin group compared to the control group. There was also a reduction in the degree of severity of OM in the palifermin group (1.65 grade respect to 2.33 in the control group). Palifermin could prevent the recurrence of severe OM and improve the quality of life in patients with acute lymphoblastic leukemia (ALL). PMID:26428409

    20% of children suffering from high hyperdiploid acute lymphoblastic leukemia develop recurrent disease. The molecular mechanisms are largely unknown. Here, we analyzed the genetic landscape of five patients at relapse, who developed recurrent disease without prior high-risk indication using whole-exome- and whole-genome-sequencing. Oncogenic mutations of RAS pathway genes (NRAS, KRAS, FLT3, n=4) and deactivating mutations of major epigenetic regulators (CREBBP, EP300, each n=2 and ARID4B, EZH2, MACROD2, MLL2, each n=1) were prominent in these cases and virtually absent in non-recurrent cases (n=6) or other pediatric acute lymphoblastic leukemia cases (n=18). In relapse nucleotide variations were detected in cell fate determining transcription factors (GLIS1, AKNA). Structural genomic alterations affected genes regulating B-cell development (IKZF1, PBX1, RUNX1). Eleven novel translocations involved the genes ART4, C12orf60, MACROD2, TBL1XR1, LRRN4, KIAA1467, and ELMO1/MIR1200. Typically, patients harbored only single structural variations, except for one patient who displayed massive rearrangements in the context of a germline tumor suppressor TP53 mutation and a Li-Fraumeni syndrome-like family history. Another patient harbored a germline mutation in the DNA repair factor ATM. In summary, the relapse patients of our cohort were characterized by somatic mutations affecting the RAS pathway, epigenetic and developmental programs and germline mutations in DNA repair pathways.

    Mastocytosis is a myeloproliferative neoplasm characterized by clonal expansion of abnormal mast cells, ranging from the cutaneous forms of the disease to mast cell leukemia. In a significant proportion of patients, systemic mastocytosis (SM) coexists with another hematologic malignancy, termed systemic mastocytosis with an associated hematologic nonmast cell lineage disorder (SM-AHNMD). Despite the pronounced predominance of concomitant myeloid neoplasms, the much more unusual coexistence of...

    The benefit associated with chemotherapy in older patients with acute myeloid leukemia (AML) is debated. The prognostic impact of molecular mutations in these patients is unknown. We identified 79 patients with AML aged 75 years or over. Forty-two received chemotherapy and 37 supportive care only. In intensively treated patients, overall survival was longer (p < 0.001). Achieving complete remission was associated with longer survival (p < 0.001). NPM1 mutations tended to be associated with a higher complete remission rate (p = 0.12). In multivariate analysis, FLT3-ITD was associated with poorer survival (p = 0.049). Patients harboring FLT3-ITD and no NPM1 mutation had a poorer prognosis than others (p = 0.02). Intensive treatments can benefit a portion of elderly patients. FLT3-ITD and NPM1 mutational status might be useful for prognosis stratification. PMID:24724782

    Fungal infections occur in severely immunocompromised patients having profound and prolonged neutropenia. Here, we report a case of a 41-year-old female who, at the conclusion of induction chemotherapy for acute T-lymphoblastic leukemia, developed angioinvasive mucormycosis involving the appendix and liver, which presented as abdominal pain. This case is the first to provide detailed computed tomography and magnetic resonance imaging findings of angioinvasive appendiceal and hepatic mucormycosis. The implications of these findings as well as the diagnosis and management of mucormycosis, is further discussed.

    Mutations of fms-like tyrosine kinase 3 (FLT3) and nucleophosmin (NPM1) exon 12 genes are the most common abnormalities in adult acute myeloid leukemia (AML) with normal cytogenetics. To assess the prognostic impact of the two gene mutations in Chinese AML patients, we used multiplex polymerase chain reaction (PCR) and capillary electrophoresis to screen 76 AML patients with normal cytogenetics for mutations in FLT3 internal tandem duplication (FLT3/ITD) and exon 12 of the NPM1 gene. FLT3/ITD mutation was detected in 15 (19.7%) of 76 subjects, and NPM1 mutation in 20 (26.3%) subjects. Seven (9.2%) cases were positive for both FLT3/ITD and NPM1 mutations. Significantly more FLT3/ITD aberration was detected in subjects with French-American-British (FAB) M1 (42.8%). NPM1 mutation was frequently detected in subjects with M5 (47.1%) and infrequently in subjects with M2 (11.1%). FLT3 and NPM1 mutations were significantly associated with a higher white blood cell count in peripheral blood and a lower CD34 antigen expression, but not age, sex, or platelet count. Statistical analysis revealed that the FLT3/ITD-positive group had a lower complete remission (CR) rate (53.3% vs. 83.6%). Survival analysis showed that the FLT3/ITD-positive/NPM1 mutation-negative group had worse overall survival (OS) and relapse-free survival (RFS). The FLT3/ITD-positive/NPM1 mutation-positive group showed a trend towards favorable survival compared with the FLT3/ITD-positive/NPM1 mutation-negative group (P=0.069). Our results indicate that the FLT3/ITD mutation might be a prognostic factor for an unfavorable outcome in Chinese AML subjects with normal cytogenetics, while NPM1 mutation may be a favorable prognostic factor for OS and RFS in the presence of FLT3/ITD.

    2016-01-01

    Background Acute myeloid leukemia (AML) patients with mixed lineage leukemia (MLL) gene rearrangements always had a very poor prognosis. In this study, we report the incidence of MLL rearrangements in AML patients using gene analysis, as well as the clinical significance and prognostic features of these rearrangements. Material/Methods This retrospective study took place from April 2008 to November 2011 in the People’s Liberation Army General Hospital. A total 433 AML patients were screened by multiple nested reverse transcription polymerase chain reaction (RT-PCR) to determine the incidence of the 11 MLL gene rearrangements. There were 68 cases of MLL gene rearrangements, for a positive rate of 15.7%. A total of 24 patients underwent allogeneic hematopoietic stem cell transplantation (Allo-HSCT), and 34 patients received at least 4 cycles of chemotherapy. Ten patients were lost to follow-up. Results The median follow-up was 29 months. The complete remission (CR) rate was 85.4%. The overall survival (OS) was 57.4±5.9 months for the Allo-HSCT group and 21.0±2.1 months for the chemotherapy group. The Allo-HSCT group had superior survival compared with the chemotherapy group (5-year OS: 59±17% vs. 13±8%, P0.05). Multivariate analysis showed that transplantation, platelets >50×109/L at onset, and CR are associated with a better OS in MLL rearranged AML patients. Patients with thrombocytopenia and extramedullary involvement were prone to relapse. Conclusions Our results suggest that Allo-HSCT is superior to chemotherapy alone for treating MLL rearranged AML patients. Patients treated with Allo-HSCT have a better prognosis and a longer survival. CR is an independent prognostic factor for OS, and extramedullary involvement is an independent prognostic factor for DFS. MLL rearranged AML patients with thrombocytopenia at onset <50×109 had very bad OS and DFS. PMID:27373985

  6. Differentiation Therapy of Acute Myeloid Leukemia

    Elzbieta Gocek

    2011-05-01

    Full Text Available Acute Myeloid Leukemia (AML is a predominant acute leukemia among adults, characterized by accumulation of malignantly transformed immature myeloid precursors. A very attractive way to treat myeloid leukemia, which is now called ‘differentiation therapy’, was proposed as in vitro studies have shown that a variety of agents stimulate differentiation of the cell lines isolated from leukemic patients. One of the differentiation-inducing agents, all-trans retinoic acid (ATRA, which can induce granulocytic differentiation in myeloid leukemic cell lines, has been introduced into clinics to treat patients with acute promyelocytic leukemia (APL in which a PML-RARA fusion protein is generated by a t(15;17(q22;q12 chromosomal translocation. Because differentiation therapy using ATRA has significantly improved prognosis for patients with APL, many efforts have been made to find alternative differentiating agents. Since 1,25-dihydroxyvitamin D3 (1,25D is capable of inducing in vitro monocyte/macrophage differentiation of myeloid leukemic cells, clinical trials have been performed to estimate its potential to treat patients with AML or myelodysplastic syndrome (MDS. Unfortunately therapeutic concentrations of 1,25D can induce potentially fatal systemic hypercalcemia, thus limiting clinical utility of that compound. Attempts to overcome this problem have focused on the synthesis of 1,25D analogs (VDAs which retain differentiation inducing potential, but lack its hypercalcemic effects. This review aims to discuss current problems and potential solutions in differentiation therapy of AML.

    Full Text Available A Pession, R Masetti, K Kleinschmidt, A MartoniPediatric Oncology and Hematology “Lalla Seràgnoli”, University of Bologna, ItalyAbstract: A second-generation of purine nucleoside analogs, starting with clofarabine, has been developed in the course of the search for new therapeutic agents for acute childhood leukemia, especially for refractory or relapsed disease. Clofarabine is a hybrid of fludarabine and cladribine, and has shown to have antileukemic activity in acute lymphoblastic leukemia as well as in myeloid disorders. As the only new antileukemic chemotherapeutic agent to enter clinical use in the last 10 years, clofarabine was approved as an orphan drug with the primary indication of use in pediatric patients. Toxicity has been tolerable in a heavily pretreated patient population, and clofarabine has been demonstrated to be safe, both as a single agent and in combination therapies. Liver dysfunction has been the most frequently observed adverse event, but this is generally reversible. Numerous Phase I and II trials have recently been conducted, and are still ongoing in an effort to find the optimal role for clofarabine in various treatment strategies. Concomitant use of clofarabine, cytarabine, and etoposide was confirmed to be safe and effective in two independent trials. Based on the promising results when used as a salvage regimen, clofarabine is now being investigated for its potential to become part of frontline protocols.Keywords: clofarabine, pediatric acute lymphoblastic leukemia, pediatric acute myeloid leukemia

  10. Brain damage after treatment for acute lymphoblastic leukemia. A report on 34 patients with special regard to MRI findings

    Biti, G.P.; Magrini, S.M.; Villari, N.; Caramella, D.; Guazzelli, G.; Rosi, A.; Lippi, A.

    1989-01-01

    In 34 patients treated for acute lymphoblastic leukemia (ALL), central nervous system (CNS) damage was assessed by clinical evaluation and brain magnetic resonance imaging (MRI). Twenty-seven of them had been off therapy from 5 to 109 months (median 64 months) while 7 had not completed the maintenance phase of their treatment. All the patients were disease-free when evaluated. None of the 3 patients who showed clinical CNS damage during the follow-up was symptomatic when submitted to MRI, while periventricular hyperintensity in T2-weighted images, suggestive of leukoencephalopathy, was present in 8 of the 34 patients. These subclinical abnormalities appear to be more frequent, transient in nature and treatment-related in patients evaluated shortly after the induction phase. Similar MRI findings seem, on the contrary, to be consequences of the disease on the CNS when appearing in long-term survivors. (orig.).

    2013-06-01

    There have been conflicting results regarding a correlation between CD133 expression and disease outcome. To assess CD133 expression in patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) and to evaluate its correlation with the different clinical and laboratory data as well as its relation to disease outcome, the present study included 60 newly diagnosed acute leukemic patients; 30 ALL patients with a male to female ratio of 1.5:1 and their ages ranged from 9 months to 48 years, and 30 AML patients with a male to female ratio of 1:1 and their ages ranged from 17 to 66 years. Flow cytometric assessment of CD133 expression was performed on blast cells. In ALL, no correlations were elicited between CD133 expression and some monoclonal antibodies, but in AML group, there was a significant positive correlation between CD133 and HLA-DR, CD3, CD7 and TDT, CD13 and CD34. In ALL group, patients with negative CD133 expression achieved complete remission more than patients with positive CD133 expression. In AML group, there was no statistically significant association found between positive CD133 expression and treatment outcome. The Kaplan-Meier curve illustrated a high significant negative correlation between CD133 expression and the overall survival of the AML patients. CD133 expression is an independent prognostic factor in acute leukemia, especially ALL patients and its expression could characterize a group of acute leukemic patients with higher resistance to standard chemotherapy and relapse. CD133 expression was highly associated with poor prognosis in acute leukemic patients. PMID:23532815

    2012-01-01

    Signaling through the phosphatidylinositol 3-kinase (PI3K) pathway and its downstream effectors, Akt and mechanistic target of rapamycin (mTOR), is aberrantly activated in acute myeloid leukemia (AML) patients, where it contributes to leukemic cell proliferation, survival, and drug-resistance. Thus, inhibiting mTOR signaling in AML blasts could enhance their sensitivity to cytotoxic agents. Preclinical data also suggest that allosteric mTOR inhibition with rapamycin impaired leukemia initiati...

    Clofarabine has potent antileukemia activity and its inclusion in reduced-intensity conditioning (RIC) allogeneic hematopoietic stem cell transplantation (HSCT) for acute leukemia could potentially improve outcomes. We conducted a phase II study of busulfan (.8 mg/kg i.v. twice daily on days -5, -4, -3, and -2) with clofarabine (40 mg/m(2) i.v. daily on days -5, -4, -3, and -2) conditioning before allogeneic 8/8 HLA-matched related or unrelated HSCT. The primary endpoint was donor neutrophil engraftment by day +40. Secondary endpoints included nonrelapse mortality (NRM), acute and chronic graft-versus-host disease (GVHD), progression-free survival (PFS), and overall survival (OS). Thirty-four patients (acute myeloid leukemia [AML], n = 25; myelodysplastic syndromes, n = 5; and acute lymphoid leukemia, n = 4) were enrolled. Day 40+ engraftment with donor chimerism was achieved in 33 of 34 patients with 1 patient dying before count recovery. Day 100 and 1-year NRM were 5.9% (95% confidence interval [CI], 1.0 to 17.4) and 24% (95% CI, 11 to 39), respectively. The 2-year relapse rate was 26% (95% CI, 13 to 42). Cumulative incidences of acute and chronic GVHD were 21% and 44%, respectively. The 2-year PFS was 50% (95% CI, 32 to 65) and OS was 56% (95% CI, 38 to 71). For patients with AML in first complete remission, 2-year PFS and OS were both 82% (95% CI, 55 to 94). RIC with busulfan and clofarabine leads to successful engraftment with acceptable rates of NRM and GVHD. PMID:26260679

    Interaction between free-radical oxidation of lipids and dynamics of the endogenous alpha-tocopherol level in membrane erythrocytes was studied in healthy blood donors (14), acute leukemia patients before treatment (27) and persons in remission (11) after appropriate treatment by the commonly known VAMP, AVAMP and TsAMP procedures and, in some cases, by use of combinations of prednisolone and 6-mercaptopurine. Free-radical oxidation of lipids was determined by the malonic dialdehyde yield in ascorbate- and NADPH-independent oxidation systems. The studies showed an inversely proportional dependence between reduction of the alpha-tocopherol level in the acute leukemia patients blood plasma and the intensity of free radical oxidation of lipids in the erythrocyte membranes. The combined therapy recommended in the study inhibited the peroxide formation process in the erythrocyte membranes significantly and promoted restoration of the endogenous alpha-tocopherol level which facilitated a favorable course of acute leukemia and promoted possible remission.

    Purpose: We have demonstrated that toxicities are acceptable with total marrow irradiation (TMI) at 16 Gy without chemotherapy or TMI at 12 Gy and the reduced intensity regimen of fludarabine/melphalan in patients undergoing hematopoietic cell transplantation (HCT). This article reports results of a study of TMI combined with higher intensity chemotherapy regimens in 2 phase I trials in patients with advanced acute myelogenous leukemia or acute lymphoblastic leukemia (AML/ALL) who would do poorly on standard intent-to-cure HCT regimens. Methods and Materials: Trial 1 consisted of TMI on Days -10 to -6, etoposide (VP16) on Day -5 (60 mg/kg), and cyclophosphamide (CY) on Day -3 (100 mg/kg). TMI dose was 12 (n=3 patients), 13.5 (n=3 patients), and 15 (n=6 patients) Gy at 1.5 Gy twice daily. Trial 2 consisted of busulfan (BU) on Days -12 to -8 (800 {mu}M min), TMI on Days -8 to -4, and VP16 on Day -3 (30 mg/kg). TMI dose was 12 (n=18) and 13.5 (n=2) Gy at 1.5 Gy twice daily. Results: Trial 1 had 12 patients with a median age of 33 years. Six patients had induction failures (IF), and 6 had first relapses (1RL), 9 with leukemia blast involvement of bone marrow ranging from 10%-98%, 5 with circulating blasts (24%-85%), and 2 with chloromas. No dose-limiting toxicities were observed. Eleven patients achieved complete remission at Day 30. With a median follow-up of 14.75 months, 5 patients remained in complete remission from 13.5-37.7 months. Trial 2 had 20 patients with a median age of 41 years. Thirteen patients had IF, and 5 had 1RL, 2 in second relapse, 19 with marrow blasts (3%-100%) and 13 with peripheral blasts (6%-63%). Grade 4 dose-limiting toxicities were seen at 13.5 Gy (stomatitis and hepatotoxicity). Stomatitis was the most frequent toxicity in both trials. Conclusions: TMI dose escalation to 15 Gy is possible when combined with CY/VP16 and is associated with acceptable toxicities and encouraging outcomes. TMI dose escalation is not possible with BU/VP16 due to

    Chromosomal rearrangements of the human MLL (mixed lineage leukemia) gene are associated with high-risk infant, pediatric, adult and therapy-induced acute leukemias. We used long-distance inverse-polymerase chain reaction to characterize the chromosomal rearrangement of individual acute leukemia...... patients. We present data of the molecular characterization of 1590 MLL-rearranged biopsy samples obtained from acute leukemia patients. The precise localization of genomic breakpoints within the MLL gene and the involved translocation partner genes (TPGs) were determined and novel TPGs identified. All...... patients were classified according to their gender (852 females and 745 males), age at diagnosis (558 infant, 416 pediatric and 616 adult leukemia patients) and other clinical criteria. Combined data of our study and recently published data revealed a total of 121 different MLL rearrangements, of which 79...

  4. Successful Control of Disseminated Intravascular Coagulation by Recombinant Thrombomodulin during Arsenic Trioxide Treatment in Relapsed Patient with Acute Promyelocytic Leukemia

    Full Text Available Disseminated intravascular coagulation (DIC frequently occurs in patients with acute promyelocytic leukemia (APL. With the induction of therapy in APL using all-trans retinoic acid (ATRA, DIC can be controlled in most cases as ATRA usually shows immediate improvement of the APL. However, arsenic trioxide (ATO which has been used for the treatment of relapse in APL patients has shown to take time to suppress APL cells, therefore the control of DIC in APL with ATO treatment is a major problem. Recently, the recombinant soluble thrombomodulin fragment has received a lot of attention as the novel drug for the treatment of DIC with high efficacy. Here, we present a relapsed patient with APL in whom DIC was successfully and safely controlled by rTM during treatment with ATO.

    Full Text Available Abstract Background Infectious etiology in lymphoproliferative diseases has always been suspected. The pathogenic roles of human herpesvirus-6 (HHV-6 in acute leukemia have been of great interest. Discordant results to establish a link between HHV-6 activation and the genesis of acute leukemia have been observed. The objective of this study was to evaluate a possible association between HHV-6 infection and acute leukemia in children and adults, with a longitudinal follow-up at diagnosis, aplasia, remission and relapse. Methods HHV-6 load was quantified by a quantitative real-time PCR in the blood and bone marrow samples from 37 children and 36 adults with acute leukemia: 33 B acute lymphoblastic leukemia (B-ALL, 6 T acute lymphoblastic leukemia (T-ALL, 34 acute myeloid leukemia (AML. Results HHV-6 was detected in 15%, 8%, 30% and 28% of the blood samples at diagnosis, aplasia, remission and relapse, respectively. The median viral loads were 138, 244, 112 and 78 copies/million cells at diagnosis, aplasia, remission and relapse, respectively. In the bone marrow samples, HHV-6 was detected in 5%, 20% and 23% of the samples at diagnosis, remission and relapse, respectively. The median viral loads were 34, 109 and 32 copies/million cells at diagnosis, remission and relapse, respectively. According to the type of leukemia at diagnosis, HHV-6 was detected in 19% of the blood samples and in 7% of the bone marrow samples (with median viral loads at 206 and 79 copies/million cells, respectively from patients with B-ALL. For patients with AML, HHV-6 was present in 8% of the blood samples and in 4% of the bone marrow samples (with median viral loads at 68 and 12 copies/million cells, respectively. HHV-6 was more prevalent in the blood samples from children than from adults (25% and 9%, respectively and for the bone marrow (11% and 0%, respectively. All typable HHV-6 were HHV-6B species. No link was shown between neither the clinical symptoms nor the

    2009-01-01

    In patients with acute lymphoblastic leukemia (ALL), monitoring of minimal residual disease (MRD) offers a way to precisely assess early treatment response and detect relapse. Established methods to study MRD are flow cytometric detection of abnormal immunophenotypes, polymerase chain reaction (PCR) amplification of antigen-receptor genes, and PCR amplification of fusion transcripts. The strong correlation between MRD levels and risk of relapse in childhood ALL is well established; studies in...
