A systematic review and meta-analysis of the effectiveness of primary thromboprophylaxis in acute lymphoblastic leukemia during early-phase therapy including asparaginase or its prolonged form. Crit Rev Oncol Hematol 2024; 197:104347. [PMID: 38583546 DOI: 10.1016/j.critrevonc.2024.104347] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2023] [Revised: 03/31/2024] [Accepted: 04/04/2024] [Indexed: 04/09/2024] Open
Abstract
Asparaginase is essential in the initial management of acute lymphoblastic leukemia (ALL) but frequently leads to venous thromboembolism (VTE). Using anticoagulants for primary VTE prevention has been studied with no consensus. We conducted a systematic literature search in PubMed, Scopus, and Web of science and performed random-effect meta-analysis using Mantel-Haenszel method in RevMan 5.4 to analyze primary pharmacological thromboprophylaxis during asparaginase treatment in early-phase (induction, consolidation, or intensification phase) therapy in patients with ALL with all ages and followed with subgroup analysis by age. Meta-analysis of 13 articles describing the effect of antithrombin supplementation in 1375 patients showed that antithrombin prophylaxis decreases the risk of VTE by 43% (RR, 0.57; 95% CI, 0.38 - 0.83; p=0.004), with mild heterogeneity (I2=35%, p=0.10) and moderate certainty by GRADE. 8 articles included for meta-analysis of low-molecular weight heparin (LMWH) treatment in 612 patients showed that it decreased the risk of VTE by nearly 40% (RR, 0.61; 95% CI, 0.45 - 0.81; p=0.00081), with minimal heterogeneity (I2=14%, p=0.31) but low certainty. Subgroup analysis showed that only prophylaxis with antithrombin supplementation significantly decreased the VTE rate in adult patients with moderate certainty. In pediatric patients, one nonrandomized prospective study showed that LMWH combined with antithrombin has a better thromboprophylaxis effect than antithrombin alone. In the PREVAPIX-ALL trial, prophylaxis with direct factor Xa inhibitor Apixaban did not benefit children younger than 18 years except for cases of obesity. We concluded that thromboprophylaxis with antithrombin is effective in ALL patients older than 18 years during the early phase of therapy, and LMWH combined with antithrombin supplementation might be effective for pediatric patients with ALL. Apixaban is effective in pediatric ALL patients with obesity and needs further study in other high-risk patients.

Abstract
Purpose: Adolescent and young adult (AYA) patients (15-39 years old) with acute lymphoblastic leukemia (ALL) have less favorable outcomes and higher treatment-related mortality as compared with older children with ALL. Minimal data exist regarding how well AYA patients tolerate the intensity of chemotherapy at doses and regimens designed for children, and the toxicities suffered by this population at children's hospitals have not been thoroughly characterized. Methods: Pediatric Health Information Systems database was queried to analyze health care outcomes in pediatric (ages 10-14) and AYA patients (ages 15-39) with ALL hospitalized between January 1999 and December 2014. We extracted relevant ICD-9 data for each patient related to grades 3 or 4 toxicities as outlined by the NCI. Results: A total of 5345 hospital admissions met inclusion criteria, representing 4046 unique patients. Of these admissions, 2195 (41.1%) were in the AYA age group, and the remainder were in the 10-14-year-old group. AYA patients had a significantly higher incidence of intensive care unit stay but no difference in median hospital stay nor mortality. AYA patients had increased toxicities in almost every organ system as compared with older children. Conclusions: In this large multicenter US database study, we found an overall increased number of toxicities among AYA patients with ALL in children's hospitals. Compared with children between the ages of 10 and 15, AYA patients developed disproportionately higher toxicities from drugs commonly used in pediatric protocols for ALL. Prospective studies are needed to assess whether dose modifications for certain chemotherapeutics may improve the toxicity profile and health care burden of AYA patients with ALL treated in children's hospitals.

Abstract
BACKGROUND The risk of venous thromboembolism is increased in adults and enhanced by asparaginase-based chemotherapy, and venous thromboembolism introduces a secondary risk of treatment delay and premature discontinuation of key anti-leukaemic agents, potentially compromising survival. Yet, the trade-off between benefits and harms of primary thromboprophylaxis in adults with acute lymphoblastic leukaemia (ALL) treated according to asparaginase-based regimens is uncertain. OBJECTIVES: The primary objectives were to assess the benefits and harms of primary thromboprophylaxis for first-time symptomatic venous thromboembolism in adults with ALL receiving asparaginase-based therapy compared with placebo or no thromboprophylaxis. The secondary objectives were to compare the benefits and harms of different groups of primary systemic thromboprophylaxis by stratifying the main results per type of drug (heparins, vitamin K antagonists, synthetic pentasaccharides, parenteral direct thrombin inhibitors, direct oral anticoagulants, and blood-derived products for antithrombin substitution). SEARCH METHODS We conducted a comprehensive literature search on 02 June 2020, with no language restrictions, including (1) electronic searches of Pubmed/MEDLINE; Embase/Ovid; Scopus/Elsevier; Web of Science Core Collection/Clarivate Analytics; and Cochrane Central Register of Controlled Trials (CENTRAL) and (2) handsearches of (i) reference lists of identified studies and related reviews; (ii) clinical trials registries (ClinicalTrials.gov registry; the International Standard Randomized Controlled Trial Number (ISRCTN) registry; the World Health Organisation's International Clinical Trials Registry Platform (ICTRP); and pharmaceutical manufacturers of asparaginase including Servier, Takeda, Jazz Pharmaceuticals, Ohara Pharmaceuticals, and Kyowa Pharmaceuticals), and (iii) conference proceedings (from the annual meetings of the American Society of Hematology (ASH); the European Haematology Association (EHA); the American Society of Clinical Oncology (ASCO); and the International Society on Thrombosis and Haemostasis (ISTH)). We conducted all searches from 1970 (the time of introduction of asparaginase in ALL treatment). We contacted the authors of relevant studies to identify any unpublished material, missing data, or information regarding ongoing studies. SELECTION CRITERIA Randomised controlled trials (RCTs); including quasi-randomised, controlled clinical, cross-over, and cluster-randomised trial designs) comparing any parenteral/oral preemptive anticoagulant or mechanical intervention with placebo or no thromboprophylaxis, or comparing two different pre-emptive anticoagulant interventions in adults aged at least 18 years with ALL treated according to asparaginase-based chemotherapy regimens. For the description of harms, non-randomised observational studies with a control group were eligible for inclusion. DATA COLLECTION AND ANALYSIS: Using a standardised data collection form, two review authors independently screened and selected studies, extracted data, assessed risk of bias for each outcome using standardised tools (RoB 2.0 tool for RCTs and ROBINS-I tool for non-randomised studies) and the certainty of evidence for each outcome using the GRADE approach. Primary outcomes included first-time symptomatic venous thromboembolism, all-cause mortality, and major bleeding. Secondary outcomes included asymptomatic venous thromboembolism, venous thromboembolism-related mortality, adverse events (i.e. clinically relevant non-major bleeding and heparin-induced thrombocytopenia for trials using heparins), and quality of life. Analyses were performed according to the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions. For non-randomised studies, we evaluated all studies (including studies judged to be at critical risk of bias in at least one of the ROBINS-I domains) in a sensitivity analysis exploring confounding. MAIN RESULTS: We identified 23 non-randomised studies that met the inclusion criteria of this review, of which 10 studies provided no outcome data for adults with ALL. We included the remaining 13 studies in the 'Risk of bias' assessment, in which we identified invalid control group definition in two studies and judged outcomes of nine studies to be at critical risk of bias in at least one of the ROBINS-I domains and outcomes of two studies at serious risk of bias. We did not assess the benefits of thromboprophylaxis, as no RCTs were included. In the main descriptive analysis of harms, we included two retrospective non-randomised studies with outcomes judged to be at serious risk of bias. One study evaluated antithrombin concentrates compared to no antithrombin concentrates. We are uncertain whether antithrombin concentrates have an effect on all-cause mortality (risk ratio (RR) 0.55, 95% confidence interval (CI) 0.26 to 1.19 (intention-to-treat analysis); one study, 40 participants; very low certainty of evidence). We are uncertain whether antithrombin concentrates have an effect on venous thromboembolism-related mortality (RR 0.10, 95% CI 0.01 to 1.94 (intention-to-treat analysis); one study, 40 participants; very low certainty of evidence). We do not know whether antithrombin concentrates have an effect on major bleeding, clinically relevant non-major bleeding, and quality of life in adults with ALL treated with asparaginase-based chemotherapy, as data were insufficient. The remaining study (224 participants) evaluated prophylaxis with low-molecular-weight heparin versus no prophylaxis. However, this study reported insufficient data regarding harms including all-cause mortality, major bleeding, venous thromboembolism-related mortality, clinically relevant non-major bleeding, heparin-induced thrombocytopenia, and quality of life. In the sensitivity analysis of harms, exploring the effect of confounding, we also included nine non-randomised studies with outcomes judged to be at critical risk of bias primarily due to uncontrolled confounding. Three studies (179 participants) evaluated the effect of antithrombin concentrates and six studies (1224 participants) evaluated the effect of prophylaxis with different types of heparins. When analysing all-cause mortality; venous thromboembolism-related mortality; and major bleeding (studies of heparin only) including all studies with extractable outcomes for each comparison (antithrombin and low-molecular-weight heparin), we observed small study sizes; few events; wide CIs crossing the line of no effect; and substantial heterogeneity by visual inspection of the forest plots. Although the observed heterogeneity could arise through the inclusion of a small number of studies with differences in participants; interventions; and outcome assessments, the likelihood that bias due to uncontrolled confounding was the cause of heterogeneity is inevitable. Subgroup analyses were not possible due to insufficient data. AUTHORS' CONCLUSIONS: We do not know from the currently available evidence, if thromboprophylaxis used for adults with ALL treated according to asparaginase-based regimens is associated with clinically appreciable benefits and acceptable harms. The existing research on this question is solely of non-randomised design, seriously to critically confounded, and underpowered with substantial imprecision. Any estimates of effect based on the existing insufficient evidence is very uncertain and is likely to change with future research.

Abstract
Thromboembolism is a serious complication of induction therapy for childhood
acute lymphoblastic leukemia. We prospectively compared the efficacy and safety
of antithrombotic interventions in the consecutive leukemia trials ALL-BFM 2000
and AIEOP-BFM ALL 2009. Patients with newly diagnosed acute lymphoblastic
leukemia (n=949, age 1 to 18 years) were randomized to receive low-dose
unfractionated heparin, prophylactic low molecular weight heparin (enoxaparin)
or activity-adapted antithrombin throughout induction therapy. The primary
objective of the study was to determine whether enoxaparin or antithrombin
reduces the incidence of thromboembolism as compared to unfractionated heparin.
The principal safety outcome was hemorrhage; leukemia outcome was a secondary
endpoint. Thromboembolism occurred in 42 patients (4.4%). Patients
assigned to unfractionated heparin had a higher risk of thromboembolism
(8.0%) compared with those randomized to enoxaparin (3.5%;
P=0.011) or antithrombin (1.9%;
P<0.001). The proportion of patients who refused
antithrombotic treatment as allocated was 3% in the unfractionated
heparin or antithrombin arms, and 33% in the enoxaparin arm. Major
hemorrhage occurred in eight patients (no differences between the groups). The
5-year event-free survival was 80.9±2.2% among patients assigned
to antithrombin compared to 85.9±2.0% in the unfractionated
heparin group (P=0.06), and 86.2±2.0% in the
enoxaparin group (P=0.10). In conclusion, prophylactic use of
antithrombin or enoxaparin significantly reduced thromboembolism. Despite the
considerable number of patients rejecting the assigned treatment with
subcutaneous injections, the result remains unambiguous. Thromboprophylaxis -
for the present time primarily with enoxaparin - can be recommended for children
and adolescents with acute lymphoblastic leukemia during induction therapy.
Whether and how antithrombin may affect leukemia outcome remains to be
determined.

Abstract
SummaryTreatment of acute lymphoblastic leukaemia (ALL) is frequently complicated by venous thromboembolism (VTE). The efficacy and optimal approach of VTE prevention are unclear, particularly in adult patients. We assessed the effect of thromboprophylaxis on symptomatic VTE incidence in cycle 1 of ALL treatment in adult patients. Secondly, we explored potential etiologic factors for VTE and the clinical impact of VTE on ALL outcome. We retrospectively assessed symptomatic VTE incidence and use of thromboprophylaxis in 240 adults treated for newly diagnosed ALL in the Dutch-Belgian HOVON-37 multicentre study (1999–2005). Potential etiologic factors were explored by analysis of patient and disease characteristics, impact of VTE on ALL outcome by analysis of complete remission and overall survival rates. Symptomatic VTE was observed in 24 of 240 patients (10%). Thromboprophylaxis differed by centre (prophylactic fresh frozen plasma (FFP) supplementation or no thromboprophylaxis) and was applied only during L-asparaginase in cycle 1. VTE incidence was significantly lower with FFP supplementation than without FFP (6% vs. 19%; adjusted odds ratio [OR] 0.28; 95% confidence interval [CI] 0.10–0.73). FFP did not influence antithrombin or fibrinogen plasma levels. Patients with VTE in cycle 1 had a significantly poorer complete remission rate (adjusted OR 0.18; 95% CI 0.07–0.50), particularly patients with cerebral venous thrombosis (adjusted OR 0.17; 95% CI 0.04–0.65). Our study suggests that prophylactic FFP supplementation effectively reduces symptomatic VTE incidence during ALL treatment in adults. This should be confirmed in a randomised controlled trial.

Abstract
The optimal antithrombin(AT) activity parameters for replacement as thromboprophylaxis following asparaginase remains unclear. This single-center, retrospective study evaluated two sets of AT replacement thresholds and targets in adults receiving asparaginase-containing chemotherapy. AT supplementation adhered to institutional standards, which lowered the AT activity target from 100% to 80% in 6/2014. Ninety-two patients were evaluated. Cumulative thrombosis incidence was 16% at 6 months (95%CI:6.8-24.0, maximum follow-up 315 days) with similar incidence between the 80% and 100% target groups, 14% (2 of the 14) and 13% (10 of the 78), respectively, with a small non-Line-Related DVT incidence (3%). Most thrombotic events occurred during induction chemotherapy and demonstrated no associations with replacement target, cumulative days or cumulative area under AT activity target, number of asparaginase doses, or cumulative asparaginase dose. Median estimated AT replacement expenditure was $34,963USD (IQR $16,260USD to $79,319USD) per patient. Cost-effectiveness and optimization of AT replacement for thromboprophylaxis following asparaginase requires prospective evaluation.

Abstract
The occurrence of venous thromboembolism (VTE) in acute lymphocytic leukemia patients receiving L-asparaginase therapy may cause significant morbidity, neurological sequela and possibly worse outcomes. The prophylactic use of antithrombin infusion (to keep antithrombin activity >60%) or low molecular weight heparin (LMWH) may reduce the risk of VTE. The decision to continue L-asparaginase therapy after the development of VTE should be based on anticipated benefits, severity of VTE and the ability to continue therapeutic anticoagulation. In patients receiving asparaginase rechallenge, the use of therapeutic LMWH, monitoring of anti-Xa level and antithrombin level are important. Novel oral anticoagulants are not dependent on antithrombin level, hence offer theoretical advantages over LMWH for the prevention and therapy of asparaginase-related VTE.

Abstract
The benefit of asparaginase for treating acute lymphoid leukaemia (ALL) has been well established. Native asparaginase derives from Escherichia coli (colaspase) or Erwinia chrysanthemi (crisantaspase); in a third preparation, colaspase is pegylated. Depletion of asparagine leads to decreased synthesis of procoagulant, anticoagulant, and fibrinolytic proteins, with resultant hypercoagulability and greater risk of venous thromboembolism (VTE). Colaspase and crisantaspase are not dose-equivalent, with crisantaspase displaying haemostatic toxicity only at dosages much higher and administered more frequently than those of colaspase. Cerebral venous thrombosis and pulmonary embolism are two life-endangering manifestations that occur during treatment with asparaginase particularly in children and in adults with ALL, respectively. Approximately one-third of VTEs are located in the upper extremities and are central venous line-related. Other risk factors are longer duration of asparaginase treatment and concomitant use of prednisone, anthracyclines, and oral contraceptives. The risk associated with inherited thrombophilia is uncertain but is clearly enhanced by other risk factors or by the use of prednisone. VTE prevention with fresh frozen plasma is not recommended; the efficacy of antithrombin (AT) concentrates has occasionally been reported, but these reports should be confirmed by proper studies, and AT should not be routinely employed. Therapeutic or prophylactic heparin doses are only partially effective, and direct thrombin or factor Xa inhibitors could play significant roles in the near future.

Abstract
The dramatic improvements seen in the outcome of paediatric patients with acute lymphoblastic leukaemia (ALL) have led to increasing incorporation of L-asparaginase (L-Asp) in adult treatment protocols. However, its use is associated with a disruption in the physiological balance between haemostatic and anticoagulant pathways, with the predominant clinical manifestation being thrombosis. Although L-Asp therapy is known to be associated with an acquired deficiency of antithrombin (AT), the concurrent depletion of fibrinogen and other haemostatic proteins means that the precise mechanism of thrombosis remains to be defined. In vitro coagulation assays are often prolonged but thrombosis rather than haemorrhage is the primary concern. Management of thrombotic events in these patients is based around agents that rely on AT for their anticoagulant effect, even though it is usually depleted. There is currently only limited evidence supporting the use of AT concentrates in either primary prevention or management following an established event. Evidence-based guidelines for prevention and management strategies are lacking.

Abstract
Thromboembolism (TE) is a known complication of L-asparaginase (ASP) therapy of acute lymphoblastic leukemia (ALL), possibly attributable to reduced synthesis of natural anticoagulants, in particular antithrombin (AT). This retrospective single institution study was performed to determine the TE incidence among adults undergoing induction with contemporary, ASP-containing regimens. Ten of 54 (18.5%) consecutive adults developed symptomatic, objectively confirmed TE, at a median of 5.5 days after the first ASP dose. These were notable for CNS and upper extremity localization, varied significantly according to ALL immunophenotype (precursor B: 11% vs. T cell: 33%), without apparent effect of schedule or total dose of ASP. Median baseline AT level was 94% and fell to a nadir of 47% (P < 0.0001) during ASP therapy. Prophylactic AT had been given to 17 during ASP therapy. None of these developed TE vs. 10/37 (27%) without replacement (P = 0.021). These observations merit further study to gain insight into disease and/or therapy-specific pathogenesis of TE in this population and call for the prospective evaluation of appropriate prophylactic interventions.

Abstract
BACKGROUND Asparaginase, an agent used in the treatment of acute lymphoblastic leukemia (ALL), is associated with the development of pancreatitis. The clinical course and long-term outcome of patients experiencing this complication has not been extensively detailed. PROCEDURE We reviewed the clinical course for all children with ALL diagnosed with pancreatitis at the Dana-Farber Cancer Institute/Children's Hospital Boston between 1987 and 2003. The outcome of these patients was compared with that of patients with ALL who did not experience pancreatitis. RESULTS Twenty-eight of 403 children (7%) were diagnosed with pancreatitis. Patients 10-18 years old at diagnosis had 2.4 times the risk of developing pancreatitis compared with younger patients. Pancreatitis typically occurred early in the course of therapy (median 4 weeks after first dose of asparaginase). Ninety-three percent of affected patients were hospitalized and 57% received parenteral nutrition. No patient developed chronic sequelae or died as a result of pancreatitis. Sixteen (57%) patients were re-treated with asparaginase, 10 of whom had another episode of pancreatitis. No significant differences in event-free survival were observed when comparing patients with and without a history of pancreatitis. CONCLUSION Asparaginase-associated pancreatitis was more common in older children, and caused significant acute morbidity. It tended to occur after the first few doses of asparaginase, suggesting a predisposition to this complication rather than a cumulative drug effect. Re-treatment with asparaginase after an episode of pancreatitis was associated with a high risk of recurrent pancreatitis.

Abstract
Macromolecular drugs such as proteins and gene products are presumably the most desirable therapeutic agents due to their unmatched substrate specificity and reaction efficiency. Yet, clinical use of these drugs has met with limited success, primarily due to the impermeable nature of the cell membrane that restricts cellular drug uptake to only small (<600 Da) and hydrophobic molecules. The recent discovery of the protein transduction domain (PTD) membrane-penetrating peptides, such as HIV-TAT, has finally offered the possibility of resolving this cell-membrane barrier for macromolecular drug delivery. Via covalent linkages, these PTD peptides have been shown to ferry the attached macromolecular species across membranes of all cell types, both in vitro and in vivo. Nevertheless, the lack of selectivity for PTD-mediated internalization restricts the application of this cell uptake method in clinical practice, due to concerns of inducing systemic toxicity caused by the carried drugs. Presented herein is a modified version of our previously established "ATTEMPTS" approach in delivery of macromolecular drugs, which integrates the cell-penetrating PTDs into a heparin/protamine-regulated delivery system. In vitro findings using asparaginase (ASNase) as a model macromolecular anti-tumor agent were able to validate the feasibility of this delivery system. The chemically constructed TAT-ASNase conjugates not only were able to translocate into the MOLT-4 cells and elicit the cytotoxic effects, but also this PTD-mediated intracellular drug uptake could be regulated (with on/off control) by the addition of heparin and protamine. This modified ATTEMPTS system therefore presents a new avenue of treatment of various types of cancers and other diseases with macromolecular drugs. In vitro characterization and a preliminary proof-of-concept animal investigation that demonstrates the feasibility of this PTD-mediated ASNase therapeutic system is subsequently described.

Abstract
Venous thrombosis is more frequent in patients treated for acute lymphoblastic leukaemia (ALL) than other malignancies and has distinctive causes, clinical features and remedies. The reported incidence varies from 1% to 36%, depending on the chemotherapy protocol and whether the reported cases are symptomatic or detected on screening radiography. The risk is thought to arise from increased thrombin generation at diagnosis combined with reduced thrombin inhibitory capacity due to depletion of circulating anti-thrombin (AT) by asparaginase. A number of patient and treatment variables have been reported to influence the risk of thrombosis including hereditary thrombophilia, early insertion of central venous catheters and exposure to a combination of steroids and asparaginase during induction. Erwinia asparaginase is associated with a lower risk of thrombosis compared with Escherichia coli asparaginase. The majority of symptomatic thromboses are related to central venous catheters and involve the upper venous system. Central nervous system thrombosis involving the cerebral venous sinuses is a unique feature of asparaginase-related thrombosis and is reported to occur in 1-3% of patients. Conclusive evidence to support the use of anti-coagulant treatment or AT concentrates for primary prevention is lacking, as is evidence for the efficacy of AT concentrates in the management of established thrombosis. Preventative strategies are hampered by conflicting data on factors that would enable identification of those at highest risk of thrombosis.

Abstract
L-Asparaginase is an effective antineoplastic agent, used in the acute lymphoblastic leukemia chemotherapy. It has been an integral part of combination chemotherapy protocols of pediatric acute lymphoblastic leukemia for almost 3 decades. The potential of L-asparaginase as a drug of leukemia has been a matter of discussion due to the high rate of allergic reactions exhibited by the patients receiving the medication of this enzyme drug. Frequent need of intramuscular injection has been another disadvantage associated with the native preparation. However, of late these clinical complications seem to have been addressed by modified versions of L-asparaginase. PEG-L-asparaginase proves to be most effective in this regard. It becomes important to discuss the efficacy of L-asparaginase as an antileukemic drug vis-a-vis these disadvantages. In this review, an attempt has been made to critically evaluate the pharmacological and clinical potential of various preparations of L-asparaginase as a drug. Advantages of PEG-L-asparaginase over native preparations and historical developments of therapy with l-asparaginase have also been outlined in the review below.

Abstract
The risk of thrombosis in children with acute lymphoblastic leukemia (ALL) reportedly ranges between 1% and 37%. Epidemiologic studies have usually been hampered by small numbers, making accurate estimates of thrombosis risk in ALL patients very difficult. The aim of this study was to better estimate the frequency of this complication and to define how the disease, its treatment, and the host contribute to its occurrence. We made an attempt to combine and analyze all published data on the association between pediatric ALL and thrombosis, by using a meta-analytic method. The rate of thrombosis in 1752 children from 17 prospective studies was 5.2% (95% CI: 4.2-6.4). The risk varies depending on several factors. Most of the events occurred during the induction phase of therapy. Lower doses of asparaginase (ASP) for long periods were associated with the highest incidence of thrombosis, as were anthracyclines and prednisone (instead of dexamethasone). The presence of central lines and of thrombophilic genetic abnormalities also appeared to be frequently associated with thrombosis. In conclusion, the overall thrombotic risk in ALL children was significant, and the subgroup analysis was able to identify high-risk individuals, a finding that will hopefully guide future prospective studies aimed at decreasing this risk.

Abstract
L-Asparaginase, a major component of therapy in children with acute lymphoblastic leukemia, has been shown to induce coagulopathy by inhibiting synthesis of clot-forming and clot-inhibitory proteins. The authors report the successful use of recombinant factor VIIa in a 15-year-old girl with acute lymphoblastic leukemia who had L-asparaginase-induced intracranial hemorrhage. The present case is the first to demonstrate use of rFVIIa in L-asparaginase-induced intracranial hemorrhage in a child with acute lymphoblastic leukemia.

Abstract
At diagnosis, there is evidence of increased thrombin generation in children with acute lymphoblastic leukemia (ALL), the etiology of which is unclear. However, thromboembolism (TE) in children with ALL is most commonly reported after the initiation of antileukemic therapy indicating a possible interaction of the disease and therapy. Antileukemic therapy influences the haemostatic system either by direct effect of the chemotherapeutic agents or indirectly through the effect of supportive care, e.g. central venous line (CVL) or infectious complications secondary to immunosuppression. Asparaginase and steroids are shown to induce hypercoagulable state by suppression of natural anticoagulants, especially AT and plasminogen, and by elevations in F VIII/vWF complex, respectively. In addition, steroid therapy causes hypofibrinolytic state by dose-dependent increase in plasminogen activator inhibitor 1 (PAI-1) levels. Combination of these effects coupled with increased thrombin generation may be responsible for the increased incidence of TE observed with concomitant administration of asparaginase and steroids. Further studies to delineate the mechanism of increased thrombin in generation children with ALL and effects of various chemotherapeutic agents, in isolation and in combination, on haemostatic system are needed.

Abstract
Thromboembolic events are an increasingly common secondary complication in children who are successfully treated for serious, life-threatening primary diseases. In contrast to adults, thromboembolic events are rare enough in children to hinder clinical trials assessing optimal use of antithrombotic agents. Currently, pediatric patients are treated according to guidelines extrapolated from adults. However, optimal prevention and treatment of thromboembolic events in children likely differs from such treatment for adults. The following review summarizes the available information on commonly used antithrombotic agents in children, which include standard heparin, low molecular heparin, oral anticoagulants, thrombolytic therapy, antiplatelet agents, antithrombin concentrates, and protein C concentrates. The mechanisms, dosing, monitoring, therapeutic range, factors influencing dose-response relationship, and side effects are discussed.

Abstract
The association of cancer with a hypercoagulable state is documented by numerous clinical, biochemical, pathologic, and pharmacologic studies. This association is manifested clinically by an increased incidence of intravascular thrombotic events in cancer patients and by fibrin deposition in and around tumor beds. Thromboembolic disease is a major cause of morbidity and mortality in patients with malignancy. This article discusses the complex pathogenesis of this problem and the associated laboratory and clinical syndromes with recommendations on diagnosis and treatment.

Abstract
Acquired deficiency of antithrombin (AT), which in some patients could lead to thrombosis, has been a serious side effect of protocols which incorporate E. coli L-asparaginase (ASP) for the treatment of acute lymphoblastic leukaemia (ALL). In a longitudinal, prospective, non-randomized study children with ALL (n=27) were treated according to the protocol ALL-BFM-90. During the induction phase using prednisone, vincristine, daunorubicin and ASP, AT substitution was performed in 15/27 patients, when their plasma concentration decreased below 60% of normal with a concomitant increase of D-dimer formation. After the administration of the AT concentrate the patients, plasma concentration of AT increased and remained elevated after 18, 48, and 72 h. In addition, the plasma concentration of enhanced thrombin generation, D-dimer formation and plasminogen activator inhibitor 1 decreased towards normal levels. Although the observed laboratory findings may serve as evidence for a possible clinical benefit of AT substitution during ASP treatment, further randomized studies are requested to evaluate whether the use of prophylactic AT administration could reduce the incidence of thromboembolic events in childhood acute leukaemia.

Abstract
L-Asparaginase treatment during induction therapy in acute lymphoblastic leukaemia (ALL) is known to be frequently complicated by thromboembolic events. It was recently suggested that L-asparaginase derived from Erwinia chrysanthemi alters the coagulation system less severely than does Escherichia coli asparaginase. In a series of 11 adult patients with ALL, we investigated some parameters of the coagulation system during treatment with Erwinia asparaginase. The doses employed were rather high; all patients below the age of 60 years received 15,000 U/m2 daily over 14 days. In accordance with what is known from treatment with E. coli asparaginase, we observed significant lowering of antithrombin as well as of fibrinogen. However, as to fibrinogen indeed a significant decrease had occurred prior to the institution of Erwinia asparaginase treatment. The most striking observation in the present study was that the levels of prothrombin complex, reflecting the function of K-vitamin dependent coagulation factors II, VII and X, remained within normal ranges during treatment. This indicates that these coagulation factors were not affected by Erwinia asparaginase, an observation at variance with several reports where E. coli asparaginase was investigated. This latter observation was the only finding which could lend support to the view that Erwinia asparaginase affects the coagulation system less than E. coli asparaginase. Finally, one of our patients developed a sinus thrombosis, a severe thrombotic complication.

Abstract
A randomized clinical trial of combination chemotherapy for adult acute lymphoblastic leukemia (ALL) with doxorubicin, vincristine and prednisolone with and without L-asparaginase (AdVP vs L-AdVP) was conducted, involving 58 institutions throughout Japan. After reaching complete remission (CR), patients were treated with the same regimen for more than 2 years. Among 166 evaluable cases of the 198 cases enrolled, CR rates were 63.1% (53/84) with AdVP and 64.6% (53/82) with L-AdVP (P = 0.837). Median survival times and 7-year survival rates were 12.7 months and 21.2% with AdVP, and 16.0 months and 22.3% with L-AdVP (P = 0.955 by generalized Wilcoxon test [GW], P = 0.952 by log-rank test [LR]). Median disease-free survival times and 7-year survival rates were 13.5 months and 23.8% with AdVP and 17.0 months and 30.6% with L-AdVP, showing some increments for L-AdVP but no statistical significance (P = 0.141 by GW, P = 0.300 by LR). Among the cases of extramurally confirmed FAB subtypes, CR rates were 75.9% (63/83) for the L1 subtype and 51.3% (39/76) for the L2 subtype (P = 0.001). As to adverse effects, pancreatitis was complicated more frequently in L-AdVP than in AdVP (P = 0.039). Other side effects such as hyperbilirubinemia, diabetes mellitus, diarrhea and hypofibrinogenemia were observed more frequently with L-AdVP, but with no statistical significance. Thus, addition of a single course of L-asparaginase in the induction phase of combination chemotherapy with doxorubicin, vincristine and prednisolone did not significantly enhance the effect of antileukemic treatment of adult ALL.

Abstract
The incidence of thrombotic complications chronologically related to L-asparaginase administration is retrospectively analyzed in 238 adult ALL patients treated according to the GIMEMA protocol ALL 0288. The patients (126 males and 112 females, aged 12-68 years, median 29) received E. coli L-asparaginase (L-ase) in the induction phase at a dosage of 6000 U/m2/day x 7 d starting on d 15, as well as vincristine, prednisone, daunorubicin and cyclophosphamide, the last-named by random 1:1. Ten patients (4.2%) developed thrombotic complications 5-15 d (median 11 d) after the start of L-ase treatment. The thrombotic events, which were lethal in 5 patients, involved the cerebral sinus (5 cases), the cerebral arteria (2 cases), the portal vein (1 case), the pulmonary district (1 case), and a deep vein in the lower extremity (1 case). The occurrence of these complications was not related to the general thrombotic risk factors, nor to the main clinical and laboratory data registered at diagnosis and immediately before the start of L-asparaginase treatment. The present study documents for the first time in a sufficiently large series of adult ALL patients that the incidence and the severity of thrombotic events related to L-ase administration are relevant and need further consideration.

Abstract
The changes in plasma levels of the vitamin K-dependent natural anticoagulants protein C (PC) and protein S (PS) and procoagulant factors II, IX and X were evaluated in 8 adult patients during treatment with L-asparaginase (L-ase i.v. 120,000 U/m2 over 10 days). PC anticoagulant activity and factor IX, X and II coagulant activity decreased proportionally to their half-lives to a nadir of 50-60% of pretreatment values after 2-5 L-ase infusions, suggesting that inhibition of protein synthesis rather than consumption is the main mechanism responsible for the observed changes. Free PS antigen levels declined at a rate similar to total PS antigen, reaching a nadir of 56% of pretreatment values after 3 L-ase infusions; however due to C4b-binding protein levels higher than total PS levels (p less than 0.05), they were constantly lower than the corresponding total PS antigen levels (0.05 less than p less than 0.001). This implicates that total PS antigen levels cannot be taken as an indicator of PS activity. No differences between the antigenic levels and the anticoagulant activities of PC and free PS could be observed suggesting that L-ase does not affect the mechanisms of vitamin K-dependent carboxylation of Gla-residues. The faster rate of decline of PC and PS activities relative to that of factor II may be responsible for the onset of an hypercoagulable state during the early phase of L-ase treatment.
