Gómez AM, Martínez C, González M, Luque A, Melen GJ, Martínez J, Hortelano S, Lassaletta Á, Madero L, Ramírez M. Chemokines and relapses in childhood acute lymphoblastic leukemia: A role in migration and in resistance to antileukemic drugs. Blood Cells Mol Dis 2015; 55:220-7. [PMID: 26227851 DOI: 10.1016/j.bcmd.2015.07.001] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2015] [Revised: 06/30/2015] [Accepted: 07/01/2015] [Indexed: 12/16/2022]
Abstract
We studied whether chemokines may have a role in relapses in childhood acute lymphoblastic leukemia (ALL). We compared the levels of chemokine receptors in marrow samples from 82 children with ALL at diagnosis versus 15 at relapses, and quantified the levels of chemokines in central system fluid (CSF) samples. The functional role of specific chemokines was studied in vitro and in vivo. The expression of some chemokine receptors was upregulated upon leukemic relapse, both in B- and in T-ALL, and in cases of medullary and extramedullary involvement. CXCL10 induced chemotaxis in leukemic cell lines and in primary leukemic cells, depending upon the levels of CXCR3 expression. CXCL10 specifically diminished chemotherapy-induced apoptosis on ALL cells expressing CXCR3, partially inhibiting caspase activation and maintaining the levels of the antiapoptotic protein Bcl-2. Finally, immunodeficient mice engrafted with CXCR3-expressing human leukemic cells showed decreased infiltration of marrow, spleen, and CNS after receiving a CXCR3-antagonist molecule. CXCR3 signaling in ALL may have a dual function: chemotactic for the localisation of leukemic blasts in specific niches, and it may also confer resistance to chemotherapy, enhancing the chances for relapses.

Detection of central nervous system involvement in childhood acute lymphoblastic leukemia by cytomorphology and flow cytometry of the cerebrospinal fluid. Pediatr Blood Cancer 2015; 62:951-6.

Abstract
BACKGROUND Therapy directed at the central nervous system (CNS) is an essential part of the treatment for childhood acute lymphoblastic leukemia (ALL). The current evaluation of CNS involvement based on cytomorphological examination of the cerebrospinal fluid (CSF) alone is not as sensitive with low cell counts as flow cytometric immunophenotyping (FCI) of the CSF. However, the importance of low CSF blasts counts at diagnosis is uncertain. We sought to determine the significance of FCI in relation to conventional morphological examination. PROCEDURE We retrospectively compared FCI of the CSF with cytomorphology at diagnosis or relapse of childhood ALL. All patients were diagnosed 2000-2012 in Stockholm or Umeå, Sweden. Clinical data were collected from medical records and the Nordic leukemia registry. Treatment assignment was based on morphological examination only. RESULTS The cohort was comprised of 214 patients with ALL. CSF involvement was detected by both methods in 20 patients, in 17 by FCI alone, and in one patient by cytomorphology alone. The relapse rate was higher for patients with negative cytology but positive FCI compared to those without CNS involvement using both methods. The difference was especially marked in the current protocol. However, none of the patients with negative CSF cytology but positive FCI had a CNS relapse. CONCLUSIONS FCI of the CSF increased the detection rate of CNS involvement of ALL approximately two times compared to cytomorphology. Patients with low-level CNS involvement may benefit from additional intensified systemic or CNS-directed therapy, but larger studies are needed.

Randomized trial of radiation-free central nervous system prophylaxis comparing intrathecal triple therapy with liposomal cytarabine in acute lymphoblastic leukemia. Haematologica 2015; 100:786-93.

Abstract
Developing optimal radiation-free central nervous system prophylaxis is a desirable goal in acute lymphoblastic leukemia, to avoid the long-term toxicity associated with cranial irradiation. In a randomized, phase II trial enrolling 145 adult patients, we compared intrathecal liposomal cytarabine (50 mg: 6/8 injections in B-/T-cell subsets, respectively) with intrathecal triple therapy (methotrexate/cytarabine/prednisone: 12 injections). Systemic therapy included methotrexate plus cytarabine or L-asparaginase courses, with methotrexate augmented to 2.5 and 5 g/m(2) in Philadelphia-negative B- and T-cell disease, respectively. The primary study objective was the comparative assessment of the risk/benefit ratio, combining the analysis of feasibility, toxicity and efficacy. In the liposomal cytarabine arm 17/71 patients (24%) developed grade 3-4 neurotoxicity compared to 2/74 (3%) in the triple therapy arm (P=0.0002), the median number of episodes of neurotoxicity of any grade was one per patient compared to zero, respectively (P=0.0001), and even though no permanent disabilities or deaths were registered, four patients (6%) discontinued intrathecal prophylaxis on account of these toxic side effects (P=0.06). Neurotoxicity worsened with liposomal cytarabine every 14 days (T-cell disease), and was improved by the adjunct of intrathecal dexamethasone. Two patients in the liposomal cytarabine arm suffered from a meningeal relapse (none with T-cell disease, only one after high-dose chemotherapy) compared to four in the triple therapy arm (1 with T-cell disease). While intrathecal liposomal cytarabine could contribute to improved, radiation-free central nervous system prophylaxis, the toxicity reported in this trial does not support its use at 50 mg and prompts the investigation of a lower dosage.

Abstract
We evaluated the impact of central nervous system irradiation (CNSI) on long-term health status and quality of life (QoL) of childhood lymphoblastic leukemia survivors included in the French L.E.A. (Childhood and Adolescent Leukemia) multicentric cohort. QoL was self-reported in adults and assessed by parents in children and adolescents, using adapted questionnaires. From 2004 to 2009, 630 nongrafted patients were assessed after 11.8±6.3 years from diagnosis. Patients receiving CNSI (18.6%) or chemotherapy alone (81.4%) were compared. The risk of having long-term physical effects was increased with CNSI (odds ratio=3.3; 95% confidence interval, 1.8-5.9), especially regarding growth failure, second tumor, cataract, and overweight. QoL did not differ significantly according to the treatment received, despite a tendency toward lower scores with CNSI in children and adolescents (summary score 63.6±13.3 vs. 71.7±12.4, P=0.14). Compared with French norms, adult survivors had an impaired QoL, especially in mental domains (mental composite score 45.2±9.8 vs. 47.9±2.1, P<0.001). In pediatric survivors, QoL was not impaired and even tended to be higher than population norms (summary score 71.7±12.4 vs. 70.0±4.2, P=0.054), mainly in social and relational domains. In conclusion, QoL seems to be impaired by the trauma of a life-threatening illness in childhood, as well as by the treatment received.

Abstract
PURPOSE To determine the benefit of radiation therapy (RT) in resolution of neurologic symptoms and deficits and whether the type of RT fields influences central nervous system (CNS) control in adults with CNS leukemia. METHODS AND MATERIALS A total of 163 adults from 1996 to 2012 were retrospectively analyzed. Potential associations between use of radiation and outcome were investigated by univariate and multivariate analysis. RESULTS The median survival time was 3.8 months after RT. Common presenting symptoms were headache in 79 patients (49%), cranial nerve VII deficit in 46 (28%), and cranial nerve II deficit in 44 (27%). RT was delivered to the base of skull in 48 patients (29%), to the whole brain (WB) in 67 (41%), and to the craniospinal axis (CS) in 48 (29%). Among 149 patients with a total of 233 deficits, resolution was observed in 34 deficits (15%), improvement in 126 deficits (54%), stability in 34 deficits (15%), and progression in 39 deficits (17%). The 12-month CNS progression-free survival was 77% among those receiving CS/WB and 51% among those receiving base of skull RT (P=.02). On multivariate analysis, patients who did not undergo stem cell transplantation after RT and base of skull RT were associated with worse CNS progression-free survival. CONCLUSIONS Improvement or resolution of symptoms occurred in two thirds of deficits after RT. Comprehensive radiation to the WB or CS seems to offer a better outcome, especially in isolated CNS involvement.

Abstract
BACKGROUND Chimeric antigen receptor (CAR) modified T cells targeting CD19 have shown activity in case series of patients with acute and chronic lymphocytic leukaemia and B-cell lymphomas, but feasibility, toxicity, and response rates of consecutively enrolled patients treated with a consistent regimen and assessed on an intention-to-treat basis have not been reported. We aimed to define feasibility, toxicity, maximum tolerated dose, response rate, and biological correlates of response in children and young adults with refractory B-cell malignancies treated with CD19-CAR T cells. METHODS This phase 1, dose-escalation trial consecutively enrolled children and young adults (aged 1-30 years) with relapsed or refractory acute lymphoblastic leukaemia or non-Hodgkin lymphoma. Autologous T cells were engineered via an 11-day manufacturing process to express a CD19-CAR incorporating an anti-CD19 single-chain variable fragment plus TCR zeta and CD28 signalling domains. All patients received fludarabine and cyclophosphamide before a single infusion of CD19-CAR T cells. Using a standard 3 + 3 design to establish the maximum tolerated dose, patients received either 1 × 10(6) CAR-transduced T cells per kg (dose 1), 3 × 10(6) CAR-transduced T cells per kg (dose 2), or the entire CAR T-cell product if sufficient numbers of cells to meet the assigned dose were not generated. After the dose-escalation phase, an expansion cohort was treated at the maximum tolerated dose. The trial is registered with ClinicalTrials.gov, number NCT01593696. FINDINGS Between July 2, 2012, and June 20, 2014, 21 patients (including eight who had previously undergone allogeneic haematopoietic stem-cell transplantation) were enrolled and infused with CD19-CAR T cells. 19 received the prescribed dose of CD19-CAR T cells, whereas the assigned dose concentration could not be generated for two patients (90% feasible). All patients enrolled were assessed for response. The maximum tolerated dose was defined as 1 × 10(6) CD19-CAR T cells per kg. All toxicities were fully reversible, with the most severe being grade 4 cytokine release syndrome that occurred in three (14%) of 21 patients (95% CI 3·0-36·3). The most common non-haematological grade 3 adverse events were fever (nine [43%] of 21 patients), hypokalaemia (nine [43%] of 21 patients), fever and neutropenia (eight [38%] of 21 patients), and cytokine release syndrome (three [14%) of 21 patients). INTERPRETATION CD19-CAR T cell therapy is feasible, safe, and mediates potent anti-leukaemic activity in children and young adults with chemotherapy-resistant B-precursor acute lymphoblastic leukaemia. All toxicities were reversible and prolonged B-cell aplasia did not occur. FUNDING National Institutes of Health Intramural funds and St Baldrick's Foundation.

Abstract
BACKGROUND The requirement for frequent intraventricular drug delivery in the setting of shunt dependence is particularly challenging in the treatment of central nervous system infection, neoplastic disease, and hemorrhage. This is especially relevant in the pediatric population where both hematogenous malignancy requiring intrathecal drug delivery and shunt-dependent hydrocephalus are more prevalent. Intrathecal and intraventricular chemotherapy agents can be prematurely diverted in these shunt-dependent patients. CASE DESCRIPTION We report the use of a stop-flow programmable shunt valve to maximize delivery of intraventricular chemotherapy in a child with acute lymphoblastic leukemia and disseminated intravascular coagulation who presented with spontaneous intracerebral and intraventricular hemorrhages. The patient then developed posthemorrhagic hydrocephalus and eventually progressed to shunt dependence but still required frequent intraventricular chemotherapy administration. A ventriculoperitoneal shunt, equipped with a valve that allows for near cessation of cerebrospinal fluid flow (Certas(®), Codman, Raynham, MA), and a contralateral Ommaya reservoir were inserted to maximize intraventricular dissemination of chemotherapy. CONCLUSIONS To the best of our knowledge, this is the first reported case of the use of a high-resistance programmable valve being used to virtually cease cerebrospinal fluid flow through the distal catheter temporarily in order to maximize intraventricular drug dissemination in a pediatric patient with acute lymphoblastic leukemia.

Abstract
BACKGROUND Central nervous system (CNS) involvement in childhood acute lymphoblastic leukemia (ALL) remains a therapeutic challenge. PROCEDURE To explore leukemia characteristics of patients with CNS involvement at ALL diagnosis, we analyzed clinical features and early treatment response of 744 patients on Nordic-Baltic trials. CNS status was classified as CNS1 (no CSF blasts), CNS2 (<5 leukocytes/µl CSF with blasts), CNS3 (≥5 leukocytes/µl with blasts or signs of CNS involvement), TLP+ (traumatic lumbar puncture with blasts), and TLP- (TLP with no blasts). RESULTS Patients with CNS involvement had higher leukocyte count compared with patients with CNS1 (P < 0.002). Patients with CNS3 more often had T-ALL (P < 0.001) and t(9;22)(q34;q11)[BCR-ABL1] (P < 0.004) compared with patients with CNS1. Among patients with CNS involvement headache (17%) and vomiting (14%) were most common symptoms. Symptoms or clinical findings were present among 27 of 54 patients with CNS3 versus only 7 of 39 patients with CNS2 and 15 of 75 patients with TLP+ (P < 0.001). The majority of patients with CNS involvement received additional induction therapy. The post induction bone marrow residual disease level did not differ between patients with CNS involvement and patients with CNS1 (P > 0.15). The 12-year event-free survival for patients with leukemic mass on neuroimaging did not differ from patients with negative or no scan (0.50 vs. 0.60; P = 0.7) or between patients with symptoms or signs suggestive of CNS leukemia and patients without such characteristics (0.50 vs. 0.61; P = 0.2). CONCLUSION CNS involvement at diagnosis is associated with adverse prognostic features but does not indicate a less chemosensitive leukemia.

Survivors of childhood cancer frequently experience cancer-related cognitive dysfunction, commonly months to years after treatment for pediatric brain tumors, acute lymphoblastic leukemia (ALL), or tumors involving the head and neck. Risk factors for cancer-related cognitive dysfunction include young age at diagnosis, treatment with cranial irradiation, use of parenteral or intrathecal methotrexate, female sex, and pre-existing comorbidities. Limiting use and reducing doses and volume of cranial irradiation while intensifying chemotherapy have improved survival and reduced the severity of cognitive dysfunction, especially in leukemia. Nonetheless, problems in core functional domains of attention, processing speed, working memory and visual-motor integration continue to compromise quality of life and performance. We review the epidemiology, pathophysiology and assessment of cancer-related cognitive dysfunction, the impact of treatment changes for prevention, and the broad strategies for educational and pharmacological interventions to remediate established cognitive dysfunction following childhood cancer. The increased years of life saved after childhood cancer warrants continued study toward the prevention and remediation of cancer-related cognitive dysfunction, using uniform assessments anchored in functional outcomes.

Abstract
BACKGROUND Various trials have reported improved outcomes for adolescents and young adults (AYAs) with acute lymphoblastic leukemia (ALL) who received treatment with pediatric-based regimens. Those reports prompted the current investigation of the pediatric augmented Berlin-Frankfurt-Münster (ABFM) regimen in AYA patients. The results were compared with those from a similar population that received the hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone (hyper-CVAD) regimen. METHODS Eighty-five patients ages 12 to 40 years who had Philadelphia chromosome (Ph)-negative ALL received the ABFM regimen from October 2006 through April 2012. Their outcome was compared with outcomes in 71 historic AYA patients who received hyper-CVAD from the authors' institution. Patient and disease characteristics, as well as minimal residual disease status, were analyzed for their impact on outcomes. RESULTS The complete response rate with ABFM was 94%. The 3-year complete remission duration (CRD) and overall survival (OS) rates were 70% and 74%, respectively. For patients aged ≤21 years, the 3-year CRD and OS rates were 72% and 85%, respectively; and, for patients ages 21 to 40 years, the respective rates were 69% and 60%. The initial white blood cell count was an independent predictive factor of OS and CRD. The minimal residual disease status on days 29 and 84 of therapy also were predictive of long-term outcomes. Severe regimen toxicities included transient hepatotoxicity in 35% to 39% of patients, pancreatitis in 11% of patients, osteonecrosis in 11% of patients, and thrombosis in 22% of patients. The 3-year OS rate was 74% in the ABFM group versus 71% in the hyper-CVAD group, and the corresponding 3-year CRD rate was 70% versus 66%, respectively. CONCLUSIONS ABFM was tolerable in AYA patients with ALL but was not associated with significant improvements in CRD and OS compared with hyper-CVAD.

Abstract
Dexamethasone could be more effective than prednisolone at similar anti-inflammatory doses in the treatment of childhood acute lymphoblastic leukemia. In order to check if this "superiority" of dexamethasone might be dose-dependent, we conducted a randomized phase III trial comparing dexamethasone (6 mg/m(2)/day) to prednisolone (60 mg/m(2)/day) in induction therapy. All newly diagnosed children and adolescents with acute lymphoblastic leukemia in the 58951 EORTC trial were randomized on prephase day 1 or day 8. The main endpoint was event-free survival; secondary endpoints were overall survival and toxicity. A total of 1947 patients with acute lymphoblastic leukemia were randomized. At a median follow-up of 6.9 years, the 8-year event-free survival rate was 81.5% in the dexamethasone arm and 81.2% in the prednisolone arm; the 8-year overall survival rates were 87.2% and 89.0% respectively. The 8-year incidences of isolated or combined central nervous system relapse were 2.9% and 4.5% in the dexamethasone and prednisolone arms, respectively. The incidence of grade 3-4 toxicities during induction and the frequency of osteonecrosis were similar in the two arms. In conclusion, dexamethasone and prednisolone, used respectively at the doses of 6 and 60 mg/m(2)/day during induction, were equally effective and had a similar toxicity profile. Dexamethasone decreased the 8-year central nervous system relapse incidence by 1.6%. This trial was registered at www.clinicaltrials.gov as #NCT00003728.

Abstract
The number of cancer survivors continues to increase due to the aging and growth of the population and improvements in early detection and treatment. In order for the public health community to better serve these survivors, the American Cancer Society and the National Cancer Institute collaborated to estimate the number of current and future cancer survivors using data from the Surveillance, Epidemiology, and End Results (SEER) program registries. In addition, current treatment patterns for the most common cancer types are described based on information in the National Cancer Data Base and the SEER and SEER-Medicare linked databases; treatment-related side effects are also briefly described. Nearly 14.5 million Americans with a history of cancer were alive on January 1, 2014; by January 1, 2024, that number will increase to nearly 19 million. The 3 most common prevalent cancers among males are prostate cancer (43%), colorectal cancer (9%), and melanoma (8%), and those among females are cancers of the breast (41%), uterine corpus (8%), and colon and rectum (8%). The age distribution of survivors varies substantially by cancer type. For example, the majority of prostate cancer survivors (62%) are aged 70 years or older, whereas less than one-third (32%) of melanoma survivors are in this older age group. It is important for clinicians to understand the unique medical and psychosocial needs of cancer survivors and to proactively assess and manage these issues. There are a growing number of resources that can assist patients, caregivers, and health care providers in navigating the various phases of cancer survivorship.

Bone mineral density among long-term survivors of childhood acute lymphoblastic leukemia: results from the St. Jude Lifetime Cohort Study. Pediatr Blood Cancer 2014; 61:1270-6.

Abstract
BACKGROUND The prevalence of low bone mineral density (BMD) in adult survivors of childhood acute lymphoblastic leukemia (ALL), and the degree of recovery or decline, are not well elucidated. PROCEDURE Study subjects (age ≥ 18 years and ≥10 years post-diagnosis) participated in an institutional follow-up protocol and risk-based clinical evaluation based on Children's Oncology Group guidelines. Trabecular volumetric BMD was ascertained using quantitative computed tomography, reported as age- and sex-specific Z-scores. RESULTS At median age 31 years, 5.7% of 845 subjects had a BMD Z-score of ≤-2 and 23.8% had a Z-score of -1 to -2. Cranial radiation dose of ≥24 Gy, but not cumulative methotrexate or prednisone equivalence doses, was associated with a twofold elevated risk of a BMD Z-score of ≤-1. The cranial radiation effect was stronger in females than in males. In a subset of 400 subjects, 67% of those who previously had a BMD Z-score of ≤-2 improved by one or more categories a median of 8.5 years later. CONCLUSIONS Very low BMD was relatively uncommon in this sample of adult survivors of childhood ALL, and BMD Z-scores tended to improve from adolescence to young adulthood. High-dose cranial or craniospinal radiation exposure was the primary predictor of suboptimal BMD in our study. Given that cranial radiation treatment for childhood ALL is used far more sparingly now than in earlier treatment eras, concerns about persistently low BMD among most current childhood ALL patients may be unwarranted.

Abstract
Purpose To eliminate the toxicities and sequelae of cranial irradiation (CrRT) and to minimize the adverse impact of traumatic lumbar puncture (TLP) with blasts, a prospective study of a modified CNS-directed therapy was conducted in children with acute lymphoblastic leukemia (ALL). Patients and Methods Since June 1999, children with newly diagnosed ALL have been treated with triple intrathecal therapy (TIT) alone without CrRT. The first TIT was delayed until the disappearance of blasts from peripheral blood (PB) for up to 10 days of multidrug induction, and CrRT was omitted in all patients. If PB blasts persisted on treatment day 10 (d10), the TIT was then performed. Results Of a total of 156 patients, 152 were eligible. Seventeen patients did not have PB blasts at diagnosis. Three fourths of the remaining patients achieved complete clearance of PB blasts by d10. Only hyperleukocytosis at diagnosis showed a significantly lower clearance rate. Six standard-risk patients were upgraded to high risk because of detectable PB blasts on d10. TLPs were encountered in four patients (2.6%), but none were contaminated with lymphoblasts. Neither CNS-2 (less than 5 WBCs/μL with blasts in a nontraumatic sample) nor CNS-3 (≥ 5 WBCs/μL with blasts in a nontraumatic sample or the presence of cranial nerve palsy) was present. The 5-year event-free survival and overall survival rates ± SE were 84.2% ± 3.0% and 90.6% ± 2.4%, respectively. No isolated CNS relapse occurred, but two patients experienced combined CNS relapses. The 7-year cumulative risk of any CNS relapse was 1.4% ± 1.0%. Conclusion Delaying first TIT until circulating blasts have cleared may improve CNS control in children with newly diagnosed ALL and preclude the need for CrRT.

Abstract
Integrin-mediated attachment to extracellular matrix (ECM) is crucial for cancer progression. Malignant T cells such as acute lymphoblastic leukemia (T-ALL) express β1 integrins, which mediate their interactions with ECM. However, the role of these interactions in T-ALL malignancy is still poorly explored. In the present study, we investigated the effect of collagen; an abundant ECM, on T-ALL survival and migration. We found that collagen through α2β1 integrin promotes the survival of T-ALL cell lines in the absence of growth factors. T-ALL cell survival by collagen is associated with reduced caspase activation and maintenance of Mcl-1 levels. Collagen activated both ERK and p38 MAPKs but only MAPK/ERK was required for collagen-induced T-ALL survival. However, we found that α2β1 integrin promoted T-ALL migration via both ERK and p38. Together these data indicate that α2β1 integrin signaling can represent an important signaling pathway in T-ALL pathogenesis and suggest that its blockade could be beneficial in T-ALL treatment.

Abstract
The prognosis of paediatric acute myeloid leukaemia (AML) has improved significantly over the recent decades, but still about one-third of patients relapse. These patients have a relatively poor prognosis, with a probability of long-term survival from relapse of about 35%. This can only be achieved with very intensive chemotherapy and, usually, allogeneic stem cell transplantation, leading to very significant toxicity and even treatment-related mortality. Major improvements in the treatment of paediatric relapsed AML thus are required still, and several possibilities are discussed. In case of a suspected relapse, a comprehensive diagnostic work-up has to be undertaken, because significant changes in the biological features of the AML cells may have occurred between initial diagnosis and relapse. This review discusses many practical issues that one encounters in the treatment of children with relapsed AML. It will also be of interest for those involved in translational research in AML.

Abstract
Glioblastoma multiforme (GBM) is the most common and malignant primary brain tumor with a high mortality rate. Doxorubicin (DOX) and methotrexate (MTX) showed to be effective against a wide range of tumors, but its use in GBM treatment is limited in part due to the inability to cross the blood-brain barrier (BBB). Based on recent studies demonstrating that methamphetamine (METH) increases BBB permeability, we hypothesized that it could be used as a pharmacological tool to allow the entry of potential therapeutic drugs into the brain. Nevertheless, before attempting this approach it is crucial to understand the cytotoxicity of such drug combinations. Herein, we evaluated the effects of METH on cell viability, migration, chemotaxis, and cell cycle, as well as its modulator effects on DOX or MTX-induced cytotoxicity in a human U118 GBM cell line. Our results demonstrated that both chemotherapeutic drugs DOX and MTX induced a pronounced decrease in cell viability, migration, and chemotaxis, and led to a cell cycle arrest at G2 and S phases, respectively. Additionally, METH (1 μM) neither interfered with U-118 cell viability, migration, or cell cycle nor modified DOX- or MTX-induced cytotoxicity. Noteworthy, METH by itself impaired cell chemotaxis with a similar effect to that induced by DOX or MTX alone. Overall, we can conclude that both DOX and MTX are highly cytotoxic against GBM cells and that METH, at a concentration previously shown to increase endothelial cell permeability without leading to cell death, does not interfere with the cytotoxicity of both chemotherapeutic drugs.

Abstract
The 50th anniversary of Seminars in Hematology coincides with the 50th anniversary of St. Jude Children's Research Hospital, and both milestones are inexorably linked to studies contributing to the cure of childhood acute lymphoblastic leukemia (ALL). We thought it fitting, therefore, to mark these events by traveling back in time to point out some of the achievements, institutions, study groups, and individuals that have made cure of childhood ALL a reality. In many instances, progress was driven by new ideas, while in others it was driven by new experimental tools that allowed more precise assessment of the biology of leukemic blasts and their utility in selecting therapy. We also discuss a number of contemporary advances that point the way to exciting future directions. Whatever pathways are taken, a clear challenge will be to use emerging genome-based or immunologic-based treatment options in ways that will enhance, rather than duplicate or compromise, recent gains in outcome with classic cytotoxic chemotherapy. The theme of this journey serves as a reminder of the chief ingredient of any research directed to a catastrophic disease such as ALL. It is the audacity of a small group of investigators who confronted a childhood cancer with the goal of cure, not palliation, as their mindset.

Abstract
Intrathecal and systemic methotrexate (MTX), as well as cranial radiation, are effective modalities to prevent central nervous system relapse in childhood acute lymphoblastic leukemia. Leukoencephalopathy is a well-described adverse effect of MTX therapy and is associated with a wide range of neurological sequelae. Most recent studies of MTX-induced leukoencephalopathy have focused exclusively on imaging findings, particularly magnetic resonance imaging. Here we report a case of severe MTX-induced leukoencephalopathy with unique magnetic resonance imaging findings and pathologic correlation from a brain biopsy taken during a period of active neurological symptomatology.

Abstract
Various malignancies invade the CNS sanctuary site, accounting for the vast majority of CNS neoplastic foci and contributing to significant morbidity as well as mortality. The blood-brain barrier (BBB) exhibits considerable impermeability to chemotherapeutic agents, severely limiting therapeutic options available for patients developing metastatic CNS involvement, accounting for poor outcomes. The mechanisms by which malignant cells breach the highly exclusive BBB and subsequently survive in this unique anatomical site remain poorly understood, with most of the current knowledge stemming from nonmalignant and solid malignancy models. While solid and hematologic malignancies may face different challenges once within the CNS (e.g., solid tumor parenchymal metastasis compared to masses/nodules/leptomeningeal disease in hematologic malignancies), commonality exists in the process of migrating across the BBB from the circulation. Specifically considering this last point, this review aims to survey the current mechanistic knowledge regarding malignant migration across the BBB, necessarily emphasizing the better studied solid tumor and nonmalignant models with the intention of highlighting both the current knowledge gap and additional work required to effectively consider how hematopoietic malignancies breach the CNS.

Abstract
OBJECTIVES The aim of this report was to investigate the tailored treatment strategies for isolated central nervous system (CNS) recurrence in adult patients with acute myeloid leukemia (AML). METHODS Isolated CNS recurrence was documented in 34 patients: there were 18, 6, and 10 patients with meningeal involvement type (type A), cranial nerve palsy type (type B), and myeloid sarcoma type (type C), respectively. For patients with type A, intrathecal chemotherapy was the predominant strategy. For type B, systemic HD-Ara-C with four cycles was the main treatment. For type C, cranial irradiation or craniospinal irradiation was adopted and two cycles of HD-Ara-C were given after the irradiation. RESULTS The 5-year cumulative incidence of CNS recurrence was 12.8%. There was a significantly higher WBC count (32.6∼60.8 × 10(9)/l) in patients at first diagnosis who developed CNS recurrence (all of the three types) compared with patients with no CNS recurrence (10.1 × 10(9)/l) (P = 0.005). We found that a significantly more patients with AML-M5 and 11q23 abnormalities developed CNS recurrence in type A (P < 0.001, 0.005). Twenty-four out of 34 patients (70.6%) with CNS recurrence achieved CNS complete remission at a median of 58 days (range, 30-120). The 3-year disease-free survival and overall survival estimates for all CNS recurrence patients were 21.6 and 25.3%, respectively. DISCUSSION This report indicates that the tailored CNS-directed strategy is an effective modality to treat CNS recurrence in adult AML, but further studies are needed to improve the long-term survival.

Abstract
This study aimed to investigate: (i) changes of plasma homocysteine, methionine and S-adenosylhomocysteine levels following high-dose methotrexate (HD-MTX) treatment and (ii) the correlation of these sulfur-containing amino acids with MTX-induced hepatotoxicity. Fifteen pediatric patients with acute lymphoblastic leukemia and one patient with Burkitt lymphoma, with a total of 26 treatment courses of HD-MTX, were enrolled. Homocysteine levels increased at 24 h after HD-MTX treatment, and showed marginal decreases at 48 and 72 h. Methionine levels showed a biphasic pattern, i.e. an initial decrease at 24 h followed by increases at 48 and 72 h. S-adenosylhomocysteine exhibited a marginal decrease at 24 h. Changes of homocysteine exhibited significant correlation only with a maximum increase of alanine aminotransferase or total bilirubin from baseline. This study has demonstrated, for the first time, simultaneous changes of plasma homocysteine, methionine and S-adenosylhomocysteine following HD-MTX. The potential of homocysteine as a marker of hepatotoxicity is also presented.

Abstract
Survival for adults and children with acute lymphoblastic leukaemia has risen substantially in recent years because use of improved risk-directed treatments and supportive care has widened. In nearly all developed countries, multidisciplinary panels of leukaemia experts have formulated clinical practice guidelines in which standard treatment approaches are recommended on the basis of current evidence. However, those guidelines do not take into account resource limitations in low-income countries, including financial and technical challenges. In Asia, huge disparities in economy and infrastructure exist between countries, and even among different regions in some large countries. At a consensus session held as part of the 2013 Asian Oncology Summit in Bangkok, Thailand, a panel of experts summarised recommendations for management of adult and paediatric acute lymphoblastic leukaemia. Strategies were developed for Asian countries on the basis of available financial, skill, and logistical resources and were stratified in a four-tier system according to the resources available in a particular country or region (basic, limited, enhanced, and maximum).

Abstract
With steadily improved cure rates for children with newly diagnosed acute lymphoblastic leukaemia (ALL), treating relapsed ALL has become increasingly challenging largely due to resistance to salvage therapy. Improved biological understanding of mechanisms of relapse and drug resistance, the identification of actionable molecular targets by studying leukaemic cell and host genetics, precise risk stratification with minimum residual disease measurement, and the development of new therapeutic drugs and approaches are needed to improve outcomes of relapsed patients. Molecularly targeted therapies and innovative immunotherapeutic approaches that include specialised monoclonal antibodies and cellular therapies hold promise of enhanced leukaemia cell killing with non-overlapping toxicities. Advances in preparative regimens, donor selection, and supportive care should improve the success of haemopoietic stem-cell transplantation for high-risk patients.

Abstract
L-asparaginase (L-ASNase) is an enzyme used most effectively in the treatment of acute lymphoblastic leukemia (ALL) for more than 30 years. It catalyzes the hydrolysis of amino acid l-asparagine to aspartic acid and ammonia, which leads to cell death. Clinical trials have been conducted using L-ASNase in combination with other drugs and radiotherapy, which have led to great success in the treatment of ALL. Treatments consist of induction therapy and central nervous system therapy. The achievement of complete remission in patients is associated with a few side-effects of using L-asparaginase, including pancreatitis, coagulation abnormalities and allergic reactions. Sometimes tumor cells may develop resistance to L-ASNase. To overcome these difficulties, the drug is modified by pegylation or immobilization, and also treatment protocols can be modified to increase the efficiency of the drug.

Abstract
Acute lymphoblastic leukaemia occurs in both children and adults but its incidence peaks between 2 and 5 years of age. Causation is multifactorial and exogenous or endogenous exposures, genetic susceptibility, and chance have roles. Survival in paediatric acute lymphoblastic leukaemia has improved to roughly 90% in trials with risk stratification by biological features of leukaemic cells and response to treatment, treatment modification based on patients' pharmacodynamics and pharmacogenomics, and improved supportive care. However, innovative approaches are needed to further improve survival while reducing adverse effects. Prognosis remains poor in infants and adults. Genome-wide profiling of germline and leukaemic cell DNA has identified novel submicroscopic structural genetic changes and sequence mutations that contribute to leukaemogenesis, define new disease subtypes, affect responsiveness to treatment, and might provide novel prognostic markers and therapeutic targets for personalised medicine.

Abstract
We aimed at assessing the clinical significance of the levels of acute lymphoblastic leukemia (ALL) cells in samples of cerebrospinal fluid (CSF) during therapy. We studied 990 CSF samples from 108 patients, at the time of diagnosis (108) and at each time of intrathecal therapy (882). The proportions of leukemic cells in CSF samples were assessed by flow cytometry (FCM). Patients with central nervous system (CNS) involvement at diagnosis (FCM+) showed predominantly a T-ALL, and higher percentages of known negative prognostic factors: high risk group, higher white blood cell counts, normal karyotype, and the BCR-ABL fusion gene. No differences in relapse free survival (RFS) and overall survival (OS) were observed between FCM+ versus FCM- at diagnosis. Patients with CNS involvement during therapy showed significantly older age, and higher frequencies of T-cell leukemia. We found a significantly higher RFS in patients with FCM+ during therapy. The detection of subclinical CNS disease by FCM during maintenance was associated with significantly lower 3-years RFS and 3-years OS. A sensitive methodology like FCM can be applied for a close follow-up of the levels of ALL in CFS samples, and may identify a group of patients at high risk for relapse.

Abstract
Central nervous system leukemia may present in different ways. However, intraparenchymal mass is extremely rare in childhood leukemia. Herein, we report a boy who presented with right hemiparesis and anisocoria 1 year after the cessation of the chemotherapy protocol for acute lymphoblastic leukemia. Cranial imaging demonstrated an extensive mass located in the anterior white matter of left frontal lobe, and cerebrospinal fluid examination revealed concomitant lymphoblasts. Immunohistochemical staining of the biopsy material showed neoplastic cells with positive CD10 and TdT. Complete remission was achieved with chemotherapy alone for a duration of 2 years.

Abstract
Invasion of cranial nerves and peripheral nerve roots, plexus, or nerves by non-Hodgkin lymphoma is denoted as neurolymphomatosis (NL). Four clinical patterns are recognized. Most commonly, NL presents as a painful polyneuropathy or polyradiculopathy, followed by cranial neuropathy, painless polyneuropathy, and peripheral mononeuropathy. Diagnosis of NL is challenging and requires integration of clinical information, imaging findings, and histopathologic examination of involved nerves or nonneural tissue and cerebrospinal fluid analysis. In the rare cases of primary NL, the diagnosis is often delayed. Successful therapy is contingent upon recognition of the disease and its exact neuroanatomic localization without delay. Treatment options include systemic chemotherapy and localized irradiation of bulky disease sites. Concomitant involvement of cerebrospinal fluid and systemic disease sites requires more complex regimens.

Abstract
Treatment of the central nervous system (CNS) is an essential therapy component for childhood acute lymphoblastic leukemia (ALL). Individual patient data from 47 trials addressing 16 CNS treatment comparisons were analyzed. Event-free survival (EFS) was similar for radiotherapy versus intrathecal (IT), and radiotherapy plus IT versus IV methotrexate (IV MTX) plus IT. Triple intrathecal therapy (TIT) gave similar EFS but poorer survival than intrathecal methotrexate (IT MTX), but additional IV MTX improved both outcomes. One trial resulted in similar EFS and survival with IV MTX plus IT MTX versus TIT alone. Radiotherapy can generally be replaced by IT therapy. TIT should be used with effective systemic therapy such as IV MTX.

Abstract
BACKGROUND Intensification of systemic chemotherapy with inclusion of high dose methotrexate (HDMTX) has helped omit cranial irradiation from standard risk acute lymphoblastic leukemia (ALL) protocols, thereby eliminating the adverse side effects associated with its use. Administration of HDMTX needs meticulous monitoring. Limitations in the availability of trained staff and adequate infrastructure often pose problems in the developing world. The aim of this study was (1) to treat childhood ALL with a protocol that would have reduced use of cranial irradiation and containing infusions of high-dose methotrexate HDMTX (5 g/m(2)) without compromising on survival, and (2) evaluate the experience with HDMTX in a tertiary care cancer centre in a developing country. METHODS A retrospective chart review was done of 41 consecutive children with a confirmed diagnosis of ALL who had received at least one cycle of HDMTX as part of their consolidation treatment with regard to the patient demographic profile, details of HDMTX infusion and leucovorin rescue, toxicity, additional hospitalization, delay in next cycle of chemotherapy and survival. RESULTS The clinically most significant toxicities observed were mucositis 39% (58/149) and fever 28% (42/149) together leading to additional hospital stay in 7% (11/149) cycles and neutropenia grade 3 or more in 24.8% (34/137) contributing to delay in next cycle of chemotherapy in 15% (23/149) cycles. CONCLUSION With this strategy, it was possible to omit or reduce the dose of cranial irradiation while maintaining survival outcomes. The administration of HDMTX therapy was found to be feasible and safe with the precautions described.

Abstract
BACKGROUND Treatment of acute lymphoblastic leukemia (ALL) has included the use of prophylactic cranial irradiation in up to 20% of children with high-risk disease despite known cognitive risks of this treatment modality. METHODS Patients enrolled on the St Jude ALL Total Therapy Study XV, which omitted prophylactic cranial irradiation in all patients, were assessed 120 weeks after completion of consolidation therapy (n = 243) using a comprehensive cognitive battery. χ(2) analysis was used to compare the percentage of below-average performers among the entire ALL patient group to the expected rate based on the normative sample. Univariate logistic regression was used to estimate the effect of intensity of chemotherapy (treatment arm), age at diagnosis, and sex on the probability of below-average performance. All statistical tests were two-sided. RESULTS Overall, the ALL group had a statistically significantly higher risk for below-average performance on a measure of sustained attention (67.31% more than 1 SD below the normative mean for omission errors, P < .001) but not on measures of intellectual functioning, academic skills, or memory. Patients given higher intensity chemotherapy were at greater risk for below-average performance compared with those given lower intensity therapy on measures of processing speed (27.14% vs 6.25%, P = .009) and academic abilities (Math Reasoning: 18.60% vs 3.90%, P = .008; Word Reading: 20.00% vs 2.60%, P = .007; Spelling: 27.91% vs 3.90%, P = .001) and had higher parent-reported hyperactivity (23.00% vs 9.84%, P = .018) and learning problems (35.00% vs 16.39%, P = .005). Neither age at diagnosis nor sex was associated with risk for below-average cognitive performance. CONCLUSIONS Omitting cranial irradiation may help preserve global cognitive abilities, but treatment with chemotherapy alone is not without risks. Caregiver education and development of interventions should address both early attention deficits and cognitive late effects.

Abstract
The most common cause of treatment failure in childhood acute lymphoblastic leukemia (ALL) remains relapse, occurring in ~ 15%-20% of patients. Survival of relapsed patients can be predicted by site of relapse, length of first complete remission, and immunophenotype of relapsed ALL. BM and early relapse (< 30 months from diagnosis), as well as T-ALL, are associated with worse prognosis than isolated extramedullary or late relapse (> 30 months from diagnosis). In addition, persistence of minimal residual disease (MRD) at the end of induction or consolidation therapy predicts poor outcome because children with detectable MRD are more likely to relapse than those in molecular remission, even after allogeneic hematopoietic stem cell transplantation. We offer hematopoietic stem cell transplantation to any child with high-risk features because these patients are virtually incurable with chemotherapy alone. By contrast, we treat children with first late BM relapse of B-cell precursor ALL and good clearance of MRD with a chemotherapy approach. We use both systemic and local treatment for extramedullary relapse, mainly represented by radiotherapy and, in case of testicular involvement, by orchiectomy. Innovative approaches, including new agents or strategies of immunotherapy, are under investigation in trials enrolling patients with resistant or more advanced disease.

Abstract
Improved supportive care, more precise risk stratification, and personalized chemotherapy based on the characteristics of leukemic cells and hosts (eg, pharmacokinetics and pharmacogenetics) have pushed the cure rate of childhood acute lymphoblastic leukemia to near 90%. Further increase in cure rate can be expected from the discovery of additional recurrent molecular lesions, coupled with the development of novel targeted treatment through high-throughput genomics and innovative drug-screening systems. We discuss specific areas of research that promise to further refine current treatment and to improve the cure rate and quality of life of the patients.

Diagnosis and management of acute myeloid leukemia in children and adolescents: recommendations from an international expert panel. Blood 2012; 120:3187-205. [PMID: 22879540 DOI: 10.1182/blood-2012-03-362608] [Citation(s) in RCA: 346] [Impact Index Per Article: 28.8] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/28/2022] Open
Abstract
Despite major improvements in outcome over the past decades, acute myeloid leukemia (AML) remains a life-threatening malignancy in children, with current survival rates of ∼70%. State-of-the-art recommendations in adult AML have recently been published in this journal by Döhner et al. The primary goal of an international expert panel of the International BFM Study Group AML Committee was to set standards for the management, diagnosis, response assessment, and treatment in childhood AML. This paper aims to discuss differences between childhood and adult AML, and to highlight recommendations that are specific to children. The particular relevance of new diagnostic and prognostic molecular markers in pediatric AML is presented. The general management of pediatric AML, the management of specific pediatric AML cohorts (such as infants) or subtypes of the disease occurring in children (such as Down syndrome related AML), as well as new therapeutic approaches, and the role of supportive care are discussed.
