Four Additional Doses of PEG-L-Asparaginase During the Consolidation Phase in the AIEOP-BFM ALL 2009 Protocol Do Not Improve Outcome and Increase Toxicity in High-Risk ALL: Results of a Randomized Study. J Clin Oncol 2024; 42:915-926. [PMID: 38096462 DOI: 10.1200/jco.23.01388] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Revised: 08/09/2023] [Accepted: 09/26/2023] [Indexed: 03/08/2024] Open
Abstract
PURPOSE The AIEOP-BFM ALL 2009 protocol included, at the end of the induction phase, a randomized study of patients with high-risk (HR) ALL to investigate if an intensive exposure to pegylated L-asparaginase (PEG-ASNASE, 2,500 IU/sqm once a week × 4) on top of BFM consolidation phase IB allowed us to decrease minimal residual disease (MRD) and improve outcome. PATIENTS AND METHODS A total of 1,097 patients presented, from June 2010 to February 2017, with one or more of the following HR criteria: KMT2A::AFF1 rearrangement, hypodiploidy, prednisone poor response, poor bone marrow response at day 15 (Flow MRD ≥10%), or no complete remission (CR) at the end of induction. Of them, 809 (85.1%) were randomly assigned to receive (404) or not receive (405) four weekly doses of PEG-ASNASE. RESULTS By intention to treat (ITT) analysis, there was no significant difference in the proportion of patients with polimerase chain reaction MRD ≥5 × 10-4 at the end of phase IB in the experimental versus control arm (13.9% v 17.0%, P = .25). The 5-year event-free survival (median follow-up 6.3 years) by ITT in the experimental and control arms was 70.4% (2.3) versus 75.0% (2.2; P = .18), and the 5-year overall survival was 81.5% (2.0) versus 84.0% (1.9; P = .25), respectively. The corresponding 5-year cumulative incidence of death in CR was 9.5% (1.5) versus 5.7% (1.2; P = .08), and that of relapse was 17.7% (1.9) versus 17.2% (1.9), respectively (P = .94). Adverse reactions in phase IB occurred in 22.2% and 8.9% of patients in the experimental and control arm, respectively (P < .001). CONCLUSION Additional PEG-ASNASE in phase IB did not translate into a benefit for decreasing relapse incidence but was associated with higher toxicity. Further improvements with conventional chemotherapy might be difficult in the context of intensive treatment protocols.

Abstract
Nelarabine is a nucleoside analog critical for the treatment of patients with T-cell acute lymphoblastic leukemia/lymphoma. However, clinical peripheral and central neurologic adverse events associated with nelarabine administration have been reported. Neuroimaging of brain neurotoxicity has only been described in very few reports in pediatric patients so far. Six children with diagnosed T-cell acute lymphoblastic leukemia who clinically experienced possible, probable, or definite nelarabine-induced toxicity and underwent spine and/or brain MR imaging were reviewed. Neuroimaging findings showed a mixture of patterns including features of acute toxic leukoencephalopathy (seen in 6 cases), posterior reversible encephalopathy syndrome (2 cases), involvement of deep gray structures (1 case) and brainstem (2 cases), cranial and spinal neuropathy (2 cases each), and myelopathy (2 cases). Even though neuroimaging findings are nonspecific, the goal of this article was to alert the pediatric neuroradiologists, radiologists, and clinicians about the possibility of nelarabine-induced neurotoxicity and its broad neuroimaging spectrum.

Abstract
Survival rates for children and adult patients with T-cell acute lymphoblastic leukemia (T-ALL) have improved during the past decade due to optimization of frontline multiagent chemotherapy regimens. The outcome for relapsed T-ALL after initial intensive chemotherapy is frequently fatal, however, because no effective salvage regimens have been developed. Immunotherapy and small molecule inhibitors are beginning to be tested in T-ALL and have the potential to advance the treatment, especially the frontline regimen by eradicating minimal residual disease thus inducing more durable remissions. In this paper, I review the current chemotherapy regimens for adult patients with T-ALL and summarize the novel immunotherapies and small molecule inhibitors that are currently in early phase clinical trials.

Randomized assessment of delayed intensification and two methods for parenteral methotrexate delivery in childhood B-ALL: Children's Oncology Group Studies P9904 and P9905. Leukemia 2019; 34:1006-1016.

Abstract
The delayed intensification (DI) enhanced outcome for patients with acute lymphoblastic leukemia (ALL) treated on BFM 76/79 and CCG 105 after a prednisone-based induction. Childrens Oncology Group protocols P9904/9905 evaluated DI via a post-induction randomization for eligible National Cancer Institute (NCI) standard (SR) and high-risk (HR) patients. A second randomization compared intravenous methotrexate (IV MTX) as a 24- (1 g/m2) vs. 4-h (2 g/m2) infusion. NCI SR patients received a dexamethasone-based three-drug and NCI HR/CNS 3 SR patients a prednisone-based four-drug induction. End induction MRD (minimal residual disease) was obtained but did not impact treatment. DI improved the 10-year continuous complete remission (CCR) rate; 75.5 ± 2.5% vs. 81.8 ± 2.2% p = 0.002, whereas MTX administration did not; 4-h 80.8 ± 1.9%; 24-h 81.4 ± 1.9% (p = 0.7780). Overall survival (OS) at 10 years did not differ with DI: 91.4 ± 1.6% vs. 90.9 ± 1.7% (p = 0.25) without but was higher with the 24-h MTX infusion; 4-h 91.1 ± 1.4%; 24-h 93.9 ± 1.2% (p = 0.0209). MRD predicted outcome; 10-year CCR 87.7 ± 2.2 and 82.1 ± 2.5% when MRD was <0.01% with/without DI (p = 0.007) and 54.3 ± 8% and 44 ± 8% for patients with MRD ≥ 0.01% with/without DI (p = 0.11). DI improved CCR for patients with B-ALL with and without end induction MRD.

Abstract
PURPOSE Early intensification with methotrexate (MTX) is a key component of acute lymphoblastic leukemia (ALL) therapy. Two different approaches to MTX intensification exist but had not been compared in T-cell ALL (T-ALL): the Children's Oncology Group (COG) escalating dose intravenous MTX without leucovorin rescue plus pegaspargase escalating dose, Capizzi-style, intravenous MTX (C-MTX) regimen and the Berlin-Frankfurt-Muenster (BFM) high-dose intravenous MTX (HDMTX) plus leucovorin rescue regimen. PATIENTS AND METHODS COG AALL0434 included a 2 × 2 randomization that compared the COG-augmented BFM (ABFM) regimen with either C-MTX or HDMTX during the 8-week interim maintenance phase. All patients with T-ALL, except for those with low-risk features, received prophylactic (12 Gy) or therapeutic (18 Gy for CNS3) cranial irradiation during either the consolidation (C-MTX; second month of therapy) or delayed intensification (HDMTX; seventh month of therapy) phase. RESULTS AALL0434 accrued 1,895 patients from 2007 to 2014. The 5-year event-free survival and overall survival rates for all eligible, evaluable patients with T-ALL were 83.8% (95% CI, 81.2% to 86.4%) and 89.5% (95% CI, 87.4% to 91.7%), respectively. The 1,031 patients with T-ALL but without CNS3 disease or testicular leukemia were randomly assigned to receive ABFM with C-MTX (n = 519) or HDMTX (n = 512). The estimated 5-year disease-free survival ( P = .005) and overall survival ( P = .04) rates were 91.5% (95% CI, 88.1% to 94.8%) and 93.7% (95% CI, 90.8% to 96.6%) for C-MTX and 85.3% (95% CI, 81.0%-89.5%) and 89.4% (95% CI, 85.7%-93.2%) for HDMTX. Patients assigned to C-MTX had 32 relapses, six with CNS involvement, whereas those assigned to HDMTX had 59 relapses, 23 with CNS involvement. CONCLUSION AALL0434 established that ABFM with C-MTX was superior to ABFM plus HDMTX for T-ALL in approximately 90% of patients who received CRT, with later timing for those receiving HDMTX.

[PMID: 29161980 DOI: 10.1080/10245332.2017.1404276] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 10/18/2022]
Abstract
BACKGROUND The aim of the study is to determine the prognostic relevance of CD200/ CD56 expression in adult acute lymphoblastic leukemia patients. METHODS The expression of CD200 and CD56 by blast cells was assessed by flow cytometry before the start of chemotherapy in 70 B-ALL patients. RESULTS Positive expression of CD200 was detected in forty-six patients (66%) and CD56 was detected in 7 patients (10%) out of 70 patients, respectively. Only three patients (4.3%) had co-expression for CD200+ and CD56+. Splenomegaly and thrombocytopenia were frequently observed more in CD200+ patients. Increased frequency of CD34+ was associated with CD200+and CD56+ patients. The CD200+ and CD56+ subgroups of B-ALL patients had inferior OS and disease free survival compared to CD 200- and CD 56- patients. CONCLUSIONS CD200+ and/or CD56+ positive expression in B-ALL patients at diagnosis is a poor prognostic biomarker. Identification of CD200+ and CD56+ expression at diagnosis is recommended for a better stratification of adult B-ALL patients.

Abstract
Mixed phenotype acute leukemia (MPAL) represents a poorly characterized group of acute leukemias that lack an accepted therapeutic approach and are typically associated with poor outcomes. We present our experience of genomic profiling, pretransplantation therapy, and transplantation outcomes for 36 well-characterized pediatric and adult patients with MPAL, defined according to the 2016 World Health Organization leukemia update. A predominance of acute lymphoid leukemia (ALL)-associated mutations and cytogenetic abnormalities was noted. Remission rates after induction appeared comparable among adults (20 of 23) and children (11 of 13) and among those who received ALL (10 of 11) or acute myeloid leukemia-type (21 of 25) induction. Adults underwent transplantation in first remission while children underwent transplantation in the setting of relapse or MLL rearrangement. The median follow-up among the 25 patients who underwent transplantation was 39.6 months and median overall survival was not reached. Relapse after transplantation was associated with MLL rearrangement (P = .022), reduced-intensity conditioning (P < .001), and higher WBC at diagnosis (P = .034). These data highlight differing therapeutic approaches between adult and pediatric MPAL and demonstrate favorable survival of adult MPAL patients consolidated with allogeneic hematopoietic cell transplantation.

Abstract
BACKGROUND The introduction of novel prognostic factors such as minimal residual disease (MRD) and genomic profiling has led to the reevaluation of the role of cytogenetics and other conventional factors in risk stratification for acute lymphoblastic leukemia (ALL). METHODS This study assessed the impact of baseline cytogenetics on the outcomes of 428 adult patients with Philadelphia chromosome-negative ALL who were receiving frontline chemotherapy. Three hundred thirty patients (77%) were treated with hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone-based regimens, and 98 (23%) were treated with the augmented Berlin-Frankfurt-Munster regimen. RESULTS The median age was 40 years (range, 13-86 years). One hundred eighty-six patients (43%) had diploid cytogenetics, 32 (7%) had complex cytogenetics (defined as ≥ 5 chromosomal abnormalities), 27 (6%) had low hypodiploidy/near-triploidy (Ho-Tr), 24 (6%) had high hyperdiploidy, and 24 (6%) had a mixed-lineage leukemia (MLL) rearrangement. Patients with an MLL rearrangement, Ho-Tr, or a complex karyotype had significantly worse relapse-free survival (RFS) and overall survival (OS) than the diploid group. According to a multivariate analysis including all the baseline characteristics and MRD status, Ho-Tr and a complex karyotype were independent predictive factors for worse RFS and OS. Furthermore, survival among all cytogenetic groups was similar, regardless of the treatment received. CONCLUSIONS A complex karyotype and Ho-Tr are adverse prognostic factors for adults with ALL independently of the MRD status. These findings suggest that pretreatment cytogenetics remain a valuable prognostic tool in this population. Cancer 2017;123:459-467. © 2016 American Cancer Society.

Abstract
BACKGROUND The role of day 14 (D14) bone marrow (BM) assessment in detecting increased blasts in patients undergoing induction for acute lymphoblastic leukemia (ALL) is not well defined. METHODS This study evaluated 389 adolescent and adult patients with previously untreated Philadelphia chromosome-negative ALL who received frontline induction chemotherapy and for whom a D14 BM assessment was performed. RESULTS A D14 BM blast proportion < 10% (including blast-free aplastic BM) was observed in 319 patients (82%), 10% to 29% was observed in 31 patients (8%), and ≥30% was observed in 39 patients (10%). The composite complete remission (CR)/complete remission with inadequate platelet recovery (CRp) rates for these groups were 99.7%, 87%, and 79%, respectively. The median event-free survival (EFS) was 49, 33, and 9 months, respectively (P < .001). The median overall survival (OS) was 88, 37, and 21 months, respectively (P < .001). The D14 BM blast group was the only factor predictive for the achievement of CR/CRp (P < .001). According to a multivariate analysis, the D14 BM blast group was independently prognostic for both EFS (hazard ratio [HR], 1.44; 95% confidence interval [CI], 1.12-1.85; P = .004) and OS (HR, 1.45; 95% CI, 1.14-1.85; P = .003). However, when minimal residual disease (MRD) assessment at the time of CR was added to the model, the D14 BM blast group was no longer prognostic for EFS or OS. CONCLUSIONS An assessment of residual D14 BM blasts in patients with ALL is highly predictive of the achievement of CR with induction chemotherapy and of EFS and OS. However, the D14 BM blast assessment is less prognostic of long-term outcomes when an MRD assessment is also available. Cancer 2016;122:3812-3820. © 2016 American Cancer Society.

Abstract
In acute myelogenous leukemia, the persistent detection of abnormal cytogenetics at complete remission (ACCR) is associated with inferior outcomes. However, the prognostic significance of ACCR in adult patients with acute lymphoblastic leukemia (ALL) is unknown. We evaluated 272 adult patients with ALL and abnormal cytogenetics at baseline who were treated with frontline induction chemotherapy, achieved complete remission (CR) and had cytogenetic analysis performed at the time of CR. ACCR was observed in 26 patients (9.6%). Median relapse-free survival was 22 months (95% CI, 12 months to not reached) for patients with ACCR vs. 48 months (range, 30-125 months) in patients with normal cytogenetics at CR (NCCR; P = 0.31). Median overall survival also did not differ significantly between the ACCR (99 months [range, 17 months to not reached]) and NCCR groups (67 months [range, 47 months to not reached], P = 0.86). The specificity of ACCR for minimal residual disease (MRD) positivity by multi-parameter flow cytometry (MFC) was 43%, and there was overall poor correlation between these two methods for the detection of residual disease. When patients were stratified by MRD status, the presence or absence of persistent cytogenetic abnormalities at CR did not add additional prognostic information. This study suggests that there is poor association between MRD assessment by MFC and the presence or absence of cytogenetic abnormalities at CR in adult patients with ALL. ACCR was not associated with adverse outcomes in ALL and did not add additional prognostic information when MRD status by MFC was known.

Abstract
BACKGROUND Vincristine sulfate liposome injection (VSLI; Marqibo®) is an encapsulated preparation of standard vincristine in sphingomyelin/cholesterol liposomes. Clinical trials in adults have demonstrated safety, tolerability, and activity, leading to Food and Drug Administration (FDA) approval for adults with relapsed acute lymphoblastic leukemia (ALL). Pediatric experience with VSLI is limited. PROCEDURE This single center, phase I dose escalation study examined the safety, toxicity, maximum tolerated dose, and pharmacokinetics of VSLI administered weekly to pediatric patients age <21 years with relapsed or chemotherapy-refractory solid tumors or leukemia. RESULTS Twenty-one subjects were treated in total. Median age was 13.3 years (range 2-19). Fourteen subjects completed one 28-day cycle of therapy and five subjects completed more than one cycle. No subject experienced dose-limiting toxicity (DLT) at the first dose level (1.75 mg/m(2) /dose, dose range: 2-3.7 mg). At the second dose level (2.25 mg/m(2) /dose, dose range: 1.3-4.5 mg), one subject had transient dose-limiting grade 4 transaminase elevation, and this dose level was expanded with no additional DLT observed. The second dose level then opened to an expansion phase to evaluate activity in ALL. Clinical activity included minimal residual disease negative complete remission in one subject with ALL and stable disease in nine subjects. Clearance of total vincristine was found to be approximately 100-fold lower in comparison to published data using standard vincristine. CONCLUSIONS Children tolerate 2.25 mg/m(2) /dose of weekly VSLI (the adult FDA-approved dose) with evidence for clinical activity without dose-limiting neurotoxicity. Future plans include studying VSLI as substitution for standard vincristine with combination chemotherapy in children with ALL.

Abstract
This multicenter study used the Shanghai Children's Medical Center (SCMC)-ALL-2005 protocol for treatment of young patients (<2 years old) with acute lymphoblastic leukaemia (ALL), which was designed to improve treatment outcome in Chinese paediatric patients. These aims were pursued through risk-directed stratification based on presenting clinical and genetic features, minimal residual disease (MRD) levels and treatment response. All the patients achieved completed remission with 5-year event-free survivals of 82·6 ± 9·7% (low risk), 52·6 ± 8·4% (intermediate risk), 28·6 ± 17·1% (high risk). Disease recurrence was detected in bone marrow, bone marrow plus testis, testis alone and central nervous system in 16 (24·2%), 1 (1·5%), 1 (1·5%) and 1 (1·5%) patients respectively. No deaths were reported during induction. The SCMC-ALL-2005 trial for ALL patients <2 years old indicated high remission induction and low infection and treatment-related mortality rates.

Abstract
The superiority of the pediatric protocol for adolescents with acute lymphoblastic leukemia (ALL) has already been demonstrated, however, its efficacy in young adults remains unclear. The ALL202-U protocol was conducted to examine the efficacy and feasibility of a pediatric protocol in adolescents and young adults (AYAs) with BCR–ABL-negative ALL. Patients aged 15–24 years (n=139) were treated with the same protocol used for pediatric B-ALL. The primary objective of this study was to assess the disease-free survival (DFS) rate and its secondary aims were to assess toxicity, the complete remission (CR) rate and the overall survival (OS) rate. The CR rate was 94%. The 5-year DFS and OS rates were 67% (95% confidence interval (CI) 58–75%) and 73% (95% CI 64–80%), respectively. Severe adverse events were observed at a frequency that was similar to or lower than that in children treated with the same protocol. Only insufficient maintenance therapy significantly worsened the DFS (hazard ratio 5.60, P<0.001). These results indicate that this protocol may be a feasible and highly effective treatment for AYA with BCR–ABL-negative ALL.

Children and adolescents presenting with a markedly elevated white blood cell (ME WBC) count (WBC ≥200 × 10(9) /l) comprise a unique subset of high-risk patients with acute lymphoblastic leukaemia (ALL). We evaluated the outcomes of the 251 patients (12% of the study population) with ME WBC treated on the Children's Cancer Group-1961 protocol. Patients were evaluated for early response to treatment by bone marrow morphology; those with a rapid early response were randomized to treatment regimens testing longer and stronger post-induction therapy. We found that ME WBC patients have a poorer outcome compared to those patients presenting with a WBC <200 × 10(9) /l (5-year event-free survival 62% vs. 73%, P = 0·0005). Longer duration of therapy worsened outcome for T cell ME WBC with a trend to poorer outcome in B-ALL ME WBC patients. Augmented therapy benefits T cell ME WBC patients, similar to the entire study cohort, however, there appeared to be no impact on survival for B-ALL ME WBC patients. ME WBC was not a prognostic factor for T cell patients. In patients with high risk features, B lineage disease in association with ME WBC has a negative impact on survival.

Abstract
In this issue of Blood, Willems et al describe the dependence of acute myeloid leukemia (AML) cells on glutamine for maintaining protein synthesis downstream of mammalian target of rapamycin (mTOR) and show that the enzyme asparaginase can be used to target this dependence. Using various AML cell lines, primary samples, and CD341 stem cells from healthy donors, the authors support the notion that asparaginase may offer a therapeutic benefit in AML—not from its well-known enzymatic activity, but from its “off-target” effects on glutamine levels that result in inhibition of downstream mTOR signaling, inhibition of protein synthesis, and ultimately loss of viability.

Host genetic variants of ABCB1 and IL15 influence treatment outcome in paediatric acute lymphoblastic leukaemia. Br J Cancer 2014; 110:1673-80. [PMID: 24434428 PMCID: PMC3960629 DOI: 10.1038/bjc.2014.7] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2013] [Revised: 12/11/2013] [Accepted: 12/17/2013] [Indexed: 01/06/2023] Open
Abstract
BACKGROUND Host germline variations and their potential prognostic importance is an emerging area of interest in paediatric ALL. METHODS We investigated the associations between 20 germline variations and various clinical end points in 463 children with ALL. RESULTS After adjusting for known prognostic factors, variants in two genes were found to be independently associated with poorer EFS: ABCB1 T/T at either 2677 (rs2032582) or 3435 (rs1045642) position (P=0.003) and IL15 67276493G/G (rs17015014; P=0.022). These variants showed a strong additive effect affecting outcome (P<0.001), whereby patients with both risk genotypes had the worst EFS (P=0.001), even after adjusting for MRD levels at the end of remission induction. The adverse effect of ABCB1 T/T genotypes was most pronounced in patients with favourable cytogenetics (P=0.011) while the IL15 67276493G/G genotype mainly affected patients without common chromosomal abnormalities (P=0.022). In both cytogenetic subgroups, increasing number of such risk genotypes still predicted worsening outcome (P<0.001 and=0.009, respectively). CONCLUSION These results point to the prognostic importance of host genetic variants, although the specific mechanisms remain unclarified. Inclusion of ABCB1 and IL15 variants may help improve risk assignment strategies in paediatric ALL.

Abstract
The objective of the work was to evaluate children with acute lymphoblastic leukemia (ALL) showing resistance to immediate induction chemotherapy in relation to conventional and advanced cytogenetic analysis. The study was conducted on 63 ALL children (40 males and 23 females) with age range 4.5 months-16 years (mean = 7.76 years). They included 37 cases who attained a true remission and 26 complicated by failure of remission, early relapse or death. They were subjected to history, clinical examination and investigations including CBC, BM examination, karyotyping, FISH for translocations and flowcytometry for immunophenotyping and minimal residual disease diagnosis. Cases aged < 5 years; male sex with organomegaly had better remission although statistically insignificant. Initially low HB < 8 gm/dl, high WBCs and platelet counts >50.000/mm(3) also showed better but non-significant remission rates. Most of our cases were L(2) with better remission compared to other immunophenotypes. About 40 informative karyotypes were subdivided into 15 hypodiploid, 10 pseudodiploid, 8 normal diploid and 7 hyperdiploid cases; the best remission rates were noticed among the most frequent ploidy patterns. Chromosomes 9, 11 and 22 were the most frequently involved by structural aberrations followed by chromosomes 5, 12 and 17. Resistance was noted with aberrations not encountered among remission group; deletions involving chromosomes 2p, 3q, 10p and 12q; translocations involving chromosome 5; trisomies of chromosomes 16 and 21; monosomies of 5 and X and inversions of 5 and 11. Our conclusions were that cytogenetic and molecular characterizations of childhood ALL could add prognostic criteria for proper therapy allocation.

Abstract
Approximately 90% of the 2,000 children, adolescents, and young adults enrolled each year in Children's Oncology Group acute lymphoblastic leukemia (ALL) trials will be cured. However, high-risk subsets with significantly inferior survival remain, including infants, newly diagnosed patients with age ≥10 years, white blood count ≥50,000/µl, poor early response or T-cell ALL, and relapsed ALL patients. Effective strategies to improve survival include better risk stratification, optimizing standard chemotherapy and combining targeted therapies with cytotoxic chemotherapy, the latter of which is dependent upon identification of key driver mutations present in ALL.

Abstract
Asparaginase is an expensive drug, but important in childhood acute lymphoblastic leukemia. In order to compare costs of PEGasparaginase, Erwinia asparaginase and native E. coli asparaginase, we performed a cost-analysis in the Dutch Childhood Oncology Group ALL-10 medium-risk group intensification protocol. Treatment costs were calculated based on patient level data of 84 subjects, and were related to the occurrence of allergy to PEGasparaginase. Simultaneously, decision tree and sensitivity analyses were conducted. The total costs of the intensification course of 30 weeks were $57,893 in patients without PEGasparaginase allergy (n=64). The costs were significantly higher ($113,558) in case of allergy (n=20) necessitating a switch to Erwinia asparaginase. Simulated scenarios (decision tree analysis) using native E. coli asparaginase in intensification showed that the costs of PEGasparaginase were equal to those of native E. coli asparaginase. Also after sensitivity analyses, the costs for PEGasparaginase were equal to those of native E. coli asparaginase. Intensification treatment with native E. coli asparaginase, followed by a switch to PEGasparaginase, and subsequently to Erwinia asparaginase in case of allergy had similar overall costs compared to the treatment with PEGasparaginase as the first-line drug (followed by Erwinia asparaginase in the case of allergy). PEGasparaginase is preferred over native E. coli asparaginase, because it is administered less frequently, with less day care visits. PEGasparaginase is less immunogenic than native E. coli asparaginase and is not more expensive. Asparaginase costs are mainly determined by the percentage of patients who are allergic and require a switch to Erwinia asparaginase.

Abstract
Risk-adapted therapy has been the cornerstone of treatment for pediatric B precursor acute lymphoblastic leukemia (B-ALL). Recently, age ≥ 13 years at diagnosis has been identified as a very high-risk feature for chemotherapy treated pediatric patients with B-ALL. Whether age at time of transplantation is associated with poor outcomes in adolescents and young adults (AYA) is unknown. We hypothesized that AYA receiving allogeneic hematopoietic cell transplantation (allo-HCT) would have greater relapse and inferior survival compared with children age <13 years. We reviewed the outcomes in 136 consecutive patients (age 0-30 years) with B-ALL who underwent myeloablative allo-HCT at our institution, including 79 children age <13 years (58%) and 57 AYA age 13-30 years (42%). Overall survival at 5 years was significantly lower in the AYA group (hazard ratio, 1.74; 95% confidence interval [CI], 1.04-2.95; P = .03). In addition, the AYA patients had a greater risk of transplantation-related mortality at 1 year (hazard ratio, 2.23; 95% CI, 1.01-4.90; P = .05), but no difference in relapse (relative risk, 0.85; 95% CI, 0.41-1.76; P = .66). Based on this analysis, AYA patients undergoing allo-HCT for B-ALL have significantly inferior survival and greater transplantation-related mortality compared with children age <13 years, but no difference in relapse, suggesting that allo-HCT may overcome relapse in AYA. Further improvements in peritransplantation care are needed to limit complications in AYA patients.

The degree of tumor volume reduction during the early phase of induction chemotherapy is an independent prognostic factor in patients with high-risk neuroblastoma. Cancer 2012; 119:656-64.

Abstract
BACKGROUND In patients with high-risk neuroblastoma, the reduction in primary tumor volume was measured during the early phase of induction chemotherapy as an indicator of early tumor response, and the authors investigated whether the degree of tumor volume reduction could predict outcome in these patients. METHODS Primary tumor volumes were measured both at diagnosis and at the first tumor response evaluation (after 2 or 3 cycles of induction chemotherapy) in 90 patients with high-risk neuroblastoma who had volumetrically evaluable computed tomography or magnetic resonance scans. If the tumor volume at the first response evaluation was >40% of the initial tumor volume, then the patient was categorized as a poor responder; otherwise, the patient was categorized as a good responder. Outcomes were compared according to the degree of tumor volume reduction at the first response evaluation. RESULTS The tumor volume reduction was greater in patients who remained relapse free than in patients who had a relapsed tumor (median percentage tumor volume, 21% vs 41.5%; P = .037). The 5-year relapse-free survival rate was higher in the good responders than in the poor responders (83% [95% confidence interval, 72%-94%] vs 51% [95% confidence interval, 31%-71%]; P = .002). In a multivariate analysis of relapse-free survival, a poor early response was identified as an independent, unfavorable prognostic factor (hazard ratio, 4.24; 95% confidence interval, 1.59-11.29; P = .004). CONCLUSIONS A greater reduction in tumor volume reduction the early phase of induction chemotherapy was associated with a better outcome in patients with high-risk neuroblastoma. Tailoring treatment intensity according to the early tumor response to induction chemotherapy may improve patient outcomes.

Abstract
Purpose To improve treatment outcome for childhood acute lymphoblastic leukemia (ALL), we designed the Malaysia-Singapore ALL 2003 study with treatment stratification based on presenting clinical and genetic features and minimal residual disease (MRD) levels measured by polymerase chain reaction targeting a single antigen-receptor gene rearrangement. Patients and Methods Five hundred fifty-six patients received risk-adapted therapy with a modified Berlin-Frankfurt-Münster–ALL treatment. High-risk ALL was defined by MRD ≥ 1 × 10−3 at week 12 and/or poor prednisolone response, BCR-ABL1, MLL gene rearrangements, hypodiploid less than 45 chromosomes, or induction failure; standard-risk ALL was defined by MRD ≤ 1 × 10−4 at weeks 5 and 12 and no extramedullary involvement or high-risk features. Intermediate-risk ALL included all remaining patients. Results Patients who lacked high-risk presenting features (85.7%) received remission induction therapy with dexamethasone, vincristine, and asparaginase, without anthracyclines. Six-year event-free survival (EFS) was 80.6% ± 3.5%; overall survival was 88.4% ± 3.1%. Standard-risk patients (n = 172; 31%) received significantly deintensified subsequent therapy without compromising EFS (93.2% ± 4.1%). High-risk patients (n = 101; 18%) had the worst EFS (51.8% ± 10%); EFS was 83.6% ± 4.9% in intermediate-risk patients (n = 283; 51%). Conclusion Our results demonstrate significant progress over previous trials in the region. Three-drug remission-induction therapy combined with MRD-based risk stratification to identify poor responders is an effective strategy for childhood ALL.

Abstract
BACKGROUND In the ALL-BFM 95 trial for treatment of acute lymphoblastic leukemia, response to a prednisone pre-phase (prednisone response) was used for risk stratification in combination with age and white blood cell count at diagnosis, response to induction therapy and specific genetic high-risk features. DESIGN AND METHODS Cytomorphological marrow response was prospectively assessed on Day 15 during induction, and its prognostic value was analyzed in 1,431 patients treated on ALL-BFM 95. RESULTS The 8-year probabilities of event-free survival were 86.1%, 74.5%, and 46.4% for patients with M1, M2, and M3 Day 15 marrows, respectively. Compared to prednisone response, Day 15 marrow response was superior in outcome prediction in precursor B-cell and T-cell leukemia with, however, a differential effect depending on blast lineage. Outcome was poor in T-cell leukemia patients with prednisone poor-response independent of Day 15 marrow response, whereas among patients with prednisone good-response different risk groups could be identified by Day 15 marrow response. In contrast, prednisone response lost prognostic significance in precursor B-cell leukemia when stratified by Day 15 marrow response. Age and white blood cell count retained their independent prognostic effect. CONCLUSIONS Selective addition of Day 15 marrow response to conventional stratification criteria applied on ALL-BFM 95 (currently in use in several countries as regular chemotherapy protocol for childhood acute lymphoblastic leukemia) may significantly improve risk-adapted treatment delivery. Even though cutting-edge trial risk stratification is meanwhile dominated by minimal residual disease evaluation, an improved conventional risk assessment, as presented here, could be of great importance to countries that lack the technical and/or financial resources associated with the application of minimal residual disease analysis.

Abstract
OBJECTIVE Although BIRC6/Apollon seems to play a critical role as an antiapoptotic regulator, its clinical relevance in acute leukemia remains largely elusive. Therefore, we aimed to investigate BIRC6 gene expression in childhood acute leukemia in relation to clinicopathological characteristics at presentation, therapeutic response, and prognosis. METHODS BIRC6 expression level was assessed in 75 children with acute leukemia; 30 patients with acute myeloblastic leukemia (AML) and 45 patients with acute lymphoblastic leukemia (ALL) using real-time quantitative reverse transcriptase-polymerase chain reaction. RESULTS The median level of BIRC6 expression did not differ significantly between AML and ALL patients. BIRC6 expression level was higher in patients with AML and ALL with extramedullary involvement, white blood cell (WBC) count ≥ 10 × 10(9) /L, and unfavorable cytogenetics at diagnosis. BIRC6 gene expression was higher in patients with unfavorable response to therapy at day 14, those who developed relapse or died in both leukemic groups. The best cutoff value of BIRC6 to predict therapeutic response and disease outcome was determined. AML and ALL patients with BIRC6 overexpression had significantly shorter overall and disease free survivals. CONCLUSIONS This is the first report to study BIRC6 gene in pediatric ALL. Our results suggested that BIRC6 gene expression could be considered as an adverse risk factor in childhood acute leukemia and, hence, could be used to guide therapeutic regimens.

Abstract
We analyzed the long-term outcome of 4865 patients treated in Studies 82, 87, 88, 91 and 95 for childhood acute lymphoblastic leukemia (ALL) of the Italian Association of Pediatric Hematology and Oncology (AIEOP). Treatment was characterized by progressive intensification of systemic therapy and reduction of cranial radiotherapy. A progressive improvement of results with reduction of isolated central nervous system relapse rate was obtained. Ten-year event-free survival increased from 53% in Study 82 to 72% in Study 95, whereas survival improved from 64 to 82%. Since 1991, all patients were treated according to Berlin-Frankfurt-Muenster (BFM) ALL treatment strategy. In Study 91, reduced treatment intensity (25%) yielded inferior results, but intensification of maintenance with high-dose (HD)-L-asparaginase (randomized) allowed to compensate for this disadvantage; in high-risk patients (HR, 15%), substitution of intensive polychemotherapy blocks for conventional BFM backbone failed to improve results. A marked improvement of results was obtained in HR patients when conventional BFM therapy was intensified with three polychemotherapy blocks and double delayed intensification (Study 95). The introduction of minimal residual disease monitoring and evaluation of common randomized questions by AIEOP and BFM groups in the protocol AIEOP-BFM-ALL 2000 are expected to further ameliorate treatment of children with ALL.

Abstract
The overexpression of X-linked inhibitor of apoptosis protein (XIAP), a member of IAP family protein, is intuitively expected to be associated with unfavorable clinical features in malignancies; however, there have been only a very limited number of studies reporting the clinical relevance of XIAP expression. This study was performed to investigate the prognostic relevance of XIAP expression in childhood acute myeloid leukemia (AML). In 53 children with de novo AML, the level of XIAP expression was determined by using quantitative reverse transcriptase-polymerase chain reaction and was analyzed with respect to the clinical characteristics at diagnosis and treatment outcomes. As a result, the XIAP expression was found to be higher in patients with extramedullary disease than in those without (P=0.014). In addition, XIAP overexpression (>or=median expression) was associated with an unfavorable day 7 response to induction chemotherapy and also associated with a worse 3-yr relapsefree survival rate (52.7+/-20.9% vs. 85.9+/-14.8%, P=0.014). Multivariate analyses revealed that XIAP overexpression was an independent unfavorable prognostic factor for relapse-free survival (hazard ratio, 6.16; 95% confidence interval, 1.48-25.74; P=0.013). Collectively, XIAP overexpression may be used as an unfavorable prognostic marker in childhood AML.

Abstract
The augmented Berlin-Frankfurt-Munster (aBFM) regimen has demonstrated improved outcomes in children with acute lymphomblastic leukemia (ALL), but efficacy in adults is unknown. In this retrospective study, we evaluated clinical outcomes in 29 adult ALL patients (aged 19-70) treated with standard BFM (sBFM) or dose-intensive aBFM. Patients were stratified into risk groups based on age, cytogenetic abnormalities, peripheral leukocytosis and response to induction chemotherapy. Inter-mediate risk patients less than 50 years old and all high-risk patients were assigned to aBFM. Complete remission after induction therapy was achieved in 93% of patients. Fifteen patients completed a full course of BFM chemotherapy, with seven discontinuing because of relapse, three because of toxicity, two because of transplantation and two toxic deaths. Five-year event-free survival (EFS) was 45% (95% CI 30-67%), with 39% and 50% rates of EFS observed in the aBFM and sBFM subgroups at 5 years, respectively. Overall survival at 5 years was 62% (95% CI 46-82%), with 61% and 62% in the aBFM and sBFM subgroups alive at 5 years, respectively. Two toxic deaths were observed, and infections and neuropathy were the most common toxicities. sBFM and aBFM have efficacy and toxicity comparable with other adult ALL regimens.

Abstract
BACKGROUND Pediatric ALL patients are subjected to an aggressive and continuous chemotherapy protocol, while solid tumor patients have a less intensive treatment. We studied the antioxidant status of children from the two groups and hypothesized that the antioxidant status will differ in concert with their treatment. PROCEDURE The antioxidant status in plasma of seven ALL children and that of six children treated for different solid tumors, in regard to the different treatment regimen, was compared with healthy controls. These samples were taken during therapy, just before the next cyclophosphamide treatment, to determine the accumulative oxidative stress. RESULTS Children from the ALL group (n = 7) had significantly lower thiol plasma levels than controls (P < 0.01) and their antioxidant capacity as measured by the ferric reducing ability of plasma (FRAP) was significantly lower (P < 0.01). These parameters were normal in the solid tumors group (n = 6) but plasma antioxidant capacity as measured by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay was significantly lower (P < 0.01). CONCLUSIONS Both groups had impaired plasma antioxidant status. The higher oxidative stress of children with ALL is associated with the protocol for treating ALL which is much more aggressive and frequent than that of the solid tumors. The lower antioxidant status in plasma with ALL children is probably associated with increased reactive oxygen species (ROS) as indicated by the decrease of the antioxidant activity. This oxidative stress may lead to cell death or greater sensitivity of the tumor cell to therapy, with better outcome for pediatric patients with ALL.

Abstract
BACKGROUND Catheter-associated blood stream infections (CABSI) are frequent complications encountered with cancer treatment. In order to understand which factors might predispose to CABSIs in children and young adults, we evaluated risk for infection in association with tumor type, catheter type, and setting of occurrence. METHODS All pediatric oncology patients having a central venous catheter (CVC) with a tunneled external (TE) or totally implantable design (TID) were prospectively followed for the occurrence of a CABSI for 12 months. CABSIs were defined in accordance with the guidelines published by the Centers for Disease Control, and were quantified as the number of occurrences per 1,000 device days. Rates of CABSIs were stratified by tumor histology, type of catheter design, and setting of occurrence. Statistical comparisons were made using the Mantel-Haenzel statistic and the Cox proportional hazard model. RESULTS A total of 58 CABSIs were identified in 139 patients over a period of 35,935 CVC days. The overall CABSI rate was 1.6 infections per 1,000 CVC days (95% CI 1.2, 2.1). Stratified analysis demonstrated increased risk for CABSIs in hospitalized patients having TEs, and while patients with solid tumors were also at higher risk; this association was not supported by the Cox proportional hazard model. CONCLUSION While our baseline CABSI rate was comparatively lower than for other institutions, subset analyses identified that hospitalized cancer patients having TEs are at the highest risk for developing CABSIs. Our findings may help to guide improved methods of anticipating and controlling infections in immunocompromised patients.

Abstract
We performed a retrospective comparison of presenting features, planned treatment, complete remission (CR) rate, and outcome of 321 adolescents and young adults (AYAs) ages 16 to 20 years with newly diagnosed acute lymphoblastic leukemia (ALL) who were treated on consecutive trials in either the Children's Cancer Group (CCG) or the Cancer and Leukemia Group B (CALGB) from 1988 to 2001. CR rates were identical, 90% for both CALGB and CCG AYAs. CCG AYAs had a 63% event-free survival (EFS) and 67% overall survival (OS) at 7 years in contrast to the CALGB AYAs, in which 7-year EFS was only 34% (P < .001; relative hazard rate [RHR] = 2.2) and OS was 46% (P < .001; RHR = 1.9). While CALGB AYAs aged 16 to 17 years achieved similar outcomes to all CCG AYAs with a 7-year EFS of 55%, the EFS for 18- to 20-year-old CALGB patients was only 29%. Comparison of the regimens showed that CCG AYAs received earlier and more intensive central nervous system prophylaxis and higher cumulative doses of nonmyelosuppressive agents. There were no differences in outcomes of those who reached maintenance therapy on time compared with those who were delayed. Based on these observations, a prospective study for AYAs with ALL using the more successful approach of the CCG has been initiated.

Abstract
Minimal residual disease (MRD) is an important predictor of relapse in acute lymphoblastic leukemia (ALL), but its relationship to other prognostic variables has not been fully assessed. The Children's Oncology Group studied the prognostic impact of MRD measured by flow cytometry in the peripheral blood at day 8, and in end-induction (day 29) and end-consolidation marrows in 2143 children with precursor B-cell ALL (B-ALL). The presence of MRD in day-8 blood and day-29 marrow MRD was associated with shorter event-free survival (EFS) in all risk groups; even patients with 0.01% to 0.1% day-29 MRD had poor outcome compared with patients negative for MRD patients (59% +/- 5% vs 88% +/- 1% 5-year EFS). Presence of good prognostic markers TEL-AML1 or trisomies of chromosomes 4 and 10 still provided additional prognostic information, but not in National Cancer Institute high-risk (NCI HR) patients who were MRD(+). The few patients with detectable MRD at end of consolidation fared especially poorly, with only a 43% plus or minus 7% 5-year EFS. Day-29 marrow MRD was the most important prognostic variable in multi-variate analysis. The 12% of patients with all favorable risk factors, including NCI risk group, genetics, and absence of days 8 and 29 MRD, had a 97% plus or minus 1% 5-year EFS with nonintensive therapy. These studies are registered at www.clinicaltrials.gov as NCT00005585, NCT00005596, and NCT00005603.

Abstract
PURPOSE To identify prognostic factors and to evaluate the outcome of children with acute lymphoblastic leukemia (ALL) failure after induction therapy. PATIENTS AND METHODS Between June 1993 and December 1999, 1,395 leukemic children were included in the French Acute Lymphoblastic Leukemia 93 study. RESULTS Fifty-three patients (3.8%) had a leukemic induction failure (LIF) after three- or four-drug induction therapy. In univariate analysis, high WBC count (P = .001), mediastinal mass (P = .017), T-cell phenotype (T-ALL; P = .001), t(9;22) translocation (P = .001), and a slow early response (at day 8 and/or on day 21, P = .001) were predictive of LIF. The following three prognostic groups for LIF were identified by multivariate analysis: a low-risk group with B-cell progenitor (BCP) ALL without t(9;22) (odds ratio [OR] = 1), an intermediate-risk group with T-ALL and a mediastinal mass (OR = 7.4, P < .0001), and a high-risk group with BCP-ALL and t(9;22) or T-ALL without a mediastinal mass (OR = 28.4, P < .0001). Complete remission (CR) was subsequently obtained in 43 patients (81%). The 5-year overall survival (OS) rate of the 53 patients was 30% +/- 6%. The 5-year OS rate among allogeneic graft recipients, autologous graft recipients, and after chemotherapy were 30.4% +/- 9.6% (50% +/- 26% after genoidentical transplantation), 50% +/- 17.7%, and 41.7% +/- 14.2%, respectively (P = .18). Fourteen patients (26%) were still in first CR after a median of 83 months (range, 53 to 117 months). CONCLUSION Three risk categories for LIF in children with ALL were identified. Approximately one third of patients with LIF can be successfully treated with salvage therapy overall. Subsequent CR after LIF is mandatory for cure.

Abstract
Post-transplant lymphoproliferative disorder (PTLD) is the most common treatment related malignancy that occurs after solid organ transplantation (SOT). PTLD has extended from its initial description as an Epstein-Barr virus (EBV)-driven B-cell proliferation to include EBV-negative and non B-lineage cases. T-cell PTLD (T-PTLD) is rare in both adults and children. We report two cases of pediatric T-PTLD after SOT (liver and lungs) and review cases reported in the literature. Both patients had a bimodal response to therapy with initial eradication of bulky nodal disease with regimens typically used to treat leukemia, but persistence of low-level clonal T-cells in marrow, CSF and lung in one case.

Abstract
PURPOSE The genes that encode inhibitor of apoptosis proteins are frequently overexpressed in human cancers and can be associated with resistance to therapy. The overexpression of Apollon, a member of inhibitor of apoptosis proteins, is intuitively expected to be associated with unfavorable clinical features in malignant diseases; however, there have been no clinical studies reporting the prognostic relevance of Apollon expression in human malignancies. This study was done to investigate the clinical relevance of the expression of Apollon in childhood de novo acute myeloid leukemia. EXPERIMENTAL DESIGN In 55 pediatric patients with de novo acute myeloid leukemia, the level of Apollon expression was determined by using quantitative reverse transcriptase-PCR and was analyzed with respect to the patients' clinical features and treatment outcomes. RESULTS Apollon expression was found to be higher in patients with a leukocyte number of >or=10,000/microL, patients with extramedullary disease, and patients with the French-American-British classification subtype M7. In addition, Apollon overexpression (>or=median expression) was associated with an unfavorable day 7 response to induction chemotherapy and also associated with a poorer 3-year relapse-free survival rate (48.3 +/- 11.2% versus 78.7 +/- 8.5%, P = 0.040). CONCLUSION This is the first study demonstrating the prognostic implication of the Apollon expression in human cancers, indicating that Apollon overexpression may be used as a poor prognostic marker in childhood acute myeloid leukemia through validation by further studies.

Abstract
The clinical and cytogenetic features associated with T-cell acute lymphoblastic leukemia (T-ALL) are not predictive of early treatment failure. Based on the hypothesis that microarrays might identify patients who fail therapy, we used the Affymetrix U133 Plus 2.0 chip and prediction analysis of microarrays (PAM) to profile 50 newly diagnosed patients who were treated in the Children's Oncology Group (COG) T-ALL Study 9404. We identified a 116-member genomic classifier that could accurately distinguish all 6 induction failure (IF) cases from 44 patients who achieved remission; network analyses suggest a prominent role for genes mediating cellular quiescence. Seven genes were similarly upregulated in both the genomic classifier for IF patients and T-ALL cell lines having acquired resistance to neoplastic agents, identifying potential target genes for further study in drug resistance. We tested whether our classifier could predict IF within 42 patient samples obtained from COG 8704 and, using PAM to define a smaller classifier for the U133A chip, correctly identified the single IF case and patients with persistently circulating blasts. Genetic profiling may identify T-ALL patients who are likely to fail induction and for whom alternate treatment strategies might be beneficial.

Abstract
OBJECTIVE To evaluate children with acute lymphoblastic leukemia (ALL) showing resistance to immediate induction chemotherapy in relation to conventional and advanced cytogenetic analysis. METHODS This work was conducted on 63 ALL children (40 males and 23 females) with age range 4.5 months-16 years (mean = 7.76 years). They included 37 cases attained true remission and 26 complicated by failure of remission, early relapse or death. They were subjected to history, clinical examination and investigations including CBC, BM examination, karyotyping, FISH for translocations and flowcytometry for immunophenotyping and minimal residual disease diagnosis. RESULTS Cases aged 50.000/mm3 also showed better but non-significant remission rates. Most of the present cases were L2 with better remission compared to other immunophenotypes. Forty informative karyotypes were subdivided into 15 hypodiploid, 10 pseudodiploid, 8 normal diploid and 7 hyperdiploid cases; the best remission rates were noticed among the most frequent ploidy patterns. Chromosomes 9, 11 and 22 were the most frequently involved by structural aberrations followed by chromosomes 5, 12 and 17. Resistance was noted with aberrations not encountered among remission group; deletions involving chromosomes 2p, 3q, 10p and 12q; translocations involving chromosome 5; trisomies of chromosomes 16 and 21; monosomies of 5 and X and inversions of 5 and 11. CONCLUSION Some cytogenetic and molecular characterizations of childhood ALL could add prognostic criteria for proper therapy allocation.
