Abstract
The prognosis of adult acute lymphoblastic leukemia (ALL) is variable but more often dismal. Indeed, its clinical management is challenging, current therapies inducing complete remission in 65–90% of cases, but only 30–40% of patients being cured. The major determinant of treatment failure is relapse; consequently, measurement of residual leukemic blast (minimal residual disease, MRD) has become a powerful independent prognostic indicator in adults. Numerous evidences have also supported the clinical relevance of MRD assessment for risk class assignment and treatment selection. MRD can be virtually evaluated in all ALL patients using different technologies, such as polymerase chain reaction amplification of fusion transcripts and clonal rearrangements of antigen receptor genes, flow cytometric study of leukemic immunophenotypes and, the most recent, high throughput sequencing (HTS). In this review, the authors focused on the latest developments on MRD monitoring with emphasis on the use of HTS, as well as on the clinical impact of MRD monitoring.

Abstract
Over the last decade the use of measurable residual disease (MRD) diagnostics in adult acute lymphoblastic leukemia (ALL) has expanded from a limited number of study groups in Europe and the United States to a world-wide application. In this review, we summarize the advantages and drawbacks of the current available techniques used for MRD monitoring. Through the use of three representative case studies, we highlight the advances in the use of MRD in clinical decision-making in the management of ALL in adults. We acknowledge discrepancies in MRD monitoring and treatment between different countries, reflecting differing availability, accessibility and affordability.

Abstract
Background Recurrent genetic abnormalities influence prognosis in B lymphoblastic leukemia. BCR‐ABL rearrangement is associated with higher leukocyte counts and older age at presentation. Among adults, BCR ‐ABL ‐ is the commonest recurrent abnormality whereas, IgH rearrangements are rare. Aim Aim of this study was to identify common recurrent genetic abnormalities in adult B ALL and study their association with hematological findings. Methods Bone marrow and peripheral blood from patients with B acute lymphoblastic leukemia were analyzed for complete blood counts, bone marrow morphology and cytogenetic abnormalities. The study group was divided into smaller groups based on cytogenetic abnormalities. Hematological parameters and presence of recurrent genetic abnormalities was compared across age groups and gender by non parametric tests. Results BCR‐ABL positive group had a higher leukocyte count than BCR‐ABL negative group. Among groups 1 to 5, group 1 with gains of chromosomes was associated with leucopenia and higher age at presentation. BCR‐ABL is commonest recurrent abnormality followed by IgH rearrangements. Conclusion Patients with gains of chromosomes alone have low total leukocyte counts at presentation.

Abstract
Development of BCR-ABL tyrosine kinase inhibitors (TKIs) have improved outcomes for patients diagnosed with chronic myeloid leukemia and Philadelphia chromosome positive acute lymphoblastic leukemia. However, resistance or intolerance to these TKIs still leaves some patients without many treatment options. One point mutation in particular, the T315I mutation, has been shown to be resistant to first and second generation TKIs. The third generation TKI, ponatinib, may provide an option for these patients. Ponatinib (Iclusig®), an orally available, pan-tyrosine kinase inhibitor has a unique binding mechanism allowing inhibition of BCR-ABL kinases, including those with the T315I point mutation. A Phase II study evaluated ponatinib in patients who were resistant or intolerant to nilotinib or dasatinib or patients who had the T315I mutation. In the Phase II study, ponatinib produced a major cytogenetic response in 54% of chronic phase chronic myeloid leukemia patients. It further achieved major hematologic response in 52% of patients in the accelerated phase, 31% of patients in the blast phase, and 41% of Philadelphia chromosome positive acute lymphoblastic leukemia patients. Ponatinib also showed efficacy in patients with the T315I mutation. Serious adverse events included arterial thrombosis, hepatotoxicity, cardiovascular risks, pancreatitis, hemorrhage, fluid retention, myelosuppression, rash, abdominal pain, and embryo–fetal toxicity. Due to the risk of these adverse events and potential drug interactions, the use of ponatinib must be carefully weighed against the benefits in treating patients who have limited treatment options.

Treatment of adults with acute lymphoblastic leukemia: do the specifics of the regimen matter?: Results from a prospective randomized trial. Cancer 2012; 119:1186-94.

Abstract
BACKGROUND Induction therapy for adults with acute lymphoblastic leukemia (ALL) is similar across essentially all regimens, comprised of vincristine, corticosteroids, and anthracyclines intensified with cyclophosphamide, asparaginase, or both. Given the lack of randomized data, to date, no regimen has emerged as standard. The authors previously evaluated cytarabine 3 g/m(2) daily for 5 days with mitoxantrone 80 mg/m(2) (the ALL-2 regimen) as a novel induction regimen. Compared with historic controls, the ALL-2 regimen was superior in terms of incidence of complete remission, failure with resistant disease, and activity in patients with Philadelphia chromosome (Ph)-positive ALL. METHODS The authors conducted a multicenter, prospective, randomized trial of the ALL-2 regimen compared with a standard 4-drug induction (the L-20 regimen). Patients also received consolidation, maintenance therapy, and central nervous system prophylaxis. The trial accrued patients from August 1996 to October 2004. RESULTS The median follow-up for survivors was 7 years, and the median patient age was 43 years. Responses were evaluated in 164 patients. The treatment arms were balanced in terms of pretreatment characteristics. The frequency of complete remission for the ALL-2 regimen versus the L-20 regimen was 83% versus 71% (P = .06). More patients on the L-20 arm failed with resistant disease (21% vs 8%; P = .02). Induction deaths were comparable at 9% (ALL-2) versus 7% (L-20). The median survival was similar; and, at 5 years, the survival rate was 33% alive on the ALL-2 arm versus 27% on the L-20. CONCLUSIONS Despite superior results of induction therapy with the ALL-2 regimen, this treatment did not improve long-term outcomes. When coupled to the reported experience of other studies in adults with ALL, the results of this randomized trial raise the possibility that ultimate outcomes in adult ALL may be independent of the specific regimen chosen.

Abstract
The purpose of evaluating prognostic factors in acute lymphoblastic leukemia is, first, to stratify patients into adverse- or good-risk groups, second, to determine different treatment options accordingly and, third, to evaluate their potential outcome. Prognostic factors are particularly relevant for disease-free survival and overall survival.

Abstract
Although acute lymphoblastic leukemia is curable in one third of adult patients, results vary greatly on account of different clinical, immunologic, and cytogenetic/genetic characteristics. These data, along with the kinetics of response to early treatment, help establish the individual risk class with considerable accuracy, and support risk-specific treatments that should warrant optimal results with as little as possible nonrelapse mortality. Modern first-line therapy consists of standard- and high-dose chemotherapy (increasingly inspired to pediatric principles), hematopoietic stem-cell transplantation, and new targeted therapy, all integrated with the analysis of prognostic factors and the study of subclinical residual disease for key therapeutic decisions. These changes are improving long-term outcome, which in ongoing studies is expected close to 50% or greater.

Abstract
BACKGROUND General therapeutic options for adult patients with acute leukemia are reviewed and specific new treatment strategies are described. OBJECTIVE Treatment results and controversial issues on current and future antileukemic strategies are discussed. METHODS Data in this review came from the published literature. RESULTS/CONCLUSION In the past years, striking new developments have been noticeable in the treatment of adult acute leukemia. However, the overall outcome of adult acute leukemia remains poor, particularly in older patients. Intensive chemotherapy remains the standard for leukemia treatment but several approaches using new cytotoxic agents seem promising. Therapeutic targeting of specific biologic abnormalities present in the leukemia cell population might, in a near future, improve outcome of adult leukemia patients.

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
We evaluated patients with newly diagnosed ALL treated at the Cleveland Clinic during the years 1996 through 2005. Cox proportional hazards analysis was used to identify univariate and multivariate correlates of complete remission, overall survival and progression-free survival. On univariate analysis, significant prognostic factors included: age at diagnosis (per 10-year increase), poor risk cytogenetics, time to white blood count recovery, and time from induction chemotherapy (IC) to post-remission therapy (PRT). In patients age <60 years without poor risk cytogenetics, time from IC to PRT (per week increase) was a significant prognostic factor by multivariate analysis and was associated with a decreased progression-free survival [HR 1.27, CI (1.04-1.55), p = 0.019] and decreased overall survival [HR 1.34, CI (1.08-1.67), p = 0.009]. Delayed time from IC to PRT (> or =6.6 weeks) was associated with a statistically worse progression-free and overall survival.

Abstract
BACKGROUND Subclinical rejection (SCR) is a known entity in various solid organ transplants but not in intestinal transplantation. METHODS The purpose of this study is to characterize the presence and effect of SCR in small intestinal transplantation (Itx). A total of 151 patients who underwent Itx and maintained a functioning graft for at least 3 months after Itx were investigated. The clinicopathological characteristics associated with a SCR episode within 3 months after Itx were analyzed. Cox regression with the landmark method (the landmark time being 3 months after Itx) was used for the analyses of overall graft survival and cause-specific hazard rate of SCR. RESULTS A total of 2744 small intestinal transplant biopsies within 3 months after Itx were available for retrospective evaluation; 171 cases (6.2%) were determined as SCR and 78 patients (51.7%) experienced SCR episode within 3 months after Itx. Adult patients were associated with a significantly higher occurrence of a SCR episode (P=0.001). Overall graft survival at 5 years posttransplant for patients experiencing SCR within 3 months posttransplant and for patients without SCR was 37.2% and 60.2%, respectively (P=0.009). Cause-specific hazard rate analysis showed that a SCR episode was associated with a significantly higher hazard rate of death due to infection (P=0.005). CONCLUSIONS A SCR episode in the initial postoperative period of Itx is a significant factor for unfavorable graft prognosis, likely representing alloimmune injury ultimately resulting in patient morbidity due to infection.

Abstract
Granulocyte colony-stimulating factor (G-CSF)-supported, post-remission chemotherapy (Cx) for adult acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma (LBL) was evaluated. One hundred and forty-three eligible patients (median age, 41 years) including 126 ALL and 17 LBL receiving induction Cx (vincristine, cyclophosphamide, prednisolone [PSL], doxorubicin, L-asparaginase, intrathecal-methotrexate [IT-MTX]) were analyzed. For patients achieving complete response (CR), two courses of post-remission Cx (course A of daunorubicin, cytosine arabinoside, vindesine, PSL plus IT-MTX; course B of mitoxantrone, etoposide, vincristine, PSL plus IT-MTX) with the use of G-CSF were repeated alternately; thereafter, maintenance Cx including MTX and 6-mercaptopurine was given for 2 years. One hundred and nineteen (83%) patients achieved CR, while 14 (10%) died during induction. Among the 119 patients achieving CR, five died in remission, 76 relapsed, and the remaining 38 were alive without disease. The median survival time of the 143 eligible patients was 26 months (95% confidence interval, 19-34). At a median follow-up time of 9 years, the 5-year survival rate was 32% and the 5-year progression-free survival (PFS) rate was 26%. The 5-year survival rate of 36 patients who underwent autologous (n = 20) or allogeneic stem cell transplantation (SCT; n = 16) in the first CR group was 58%. Compared with the authors' previous trials, survival and PFS were markedly improved. In conclusion, G-CSF-supported, intensive post-remission Cx and subsequent SCT are worthy of further investigation for the treatment of adult ALL and LBL.

Abstract
We compared the gene expression profile of adult acute lymphoblastic leukemia (ALL) to normal hematopoietic and non-ALL samples using oligonucleotide arrays. Connective tissue growth factor (CTGF) was the highest overexpressed gene in B-cell ALL compared with the other groups, and displayed heterogeneous expression, suggesting it might have prognostic relevance. CTGF expression was examined by quantitative reverse transcriptase-polymerase chain reaction (ORT-PCR) on 79 adult ALL specimens. CTGF expression levels were significantly increased in ALL cases with B-lineage (P < .001), unfavorable cytogenetics (P < .001), and blasts expressing CD34 (P < .001). In a multivariate proportional hazards model, higher CTGF expression levels corresponded to worsening of overall survival (OS; hazard ratio 1.36, for each 10-fold increase in expression; P = .019). Further studies are ongoing to confirm the prognostic value of CTGF expression in ALL and to investigate its role in normal and abnormal lymphocyte biology.

Abstract
Acute lymphocytic leukemia (ALL) is a heterogeneous group of disorders that are associated with a cure rate of > 80% in children. The prognosis in adults is considerably inferior, with age, disease bulk, leukemia karyotype and immune phenotype being prognostically relevant. Adult ALL treatment programs include induction, intensified consolidation and maintenance phases with CNS prophylaxis. The addition of imatinib in patients with BCR-ABL-positive ALL has improved the prognosis of this subgroup, but their survival is still poor. Initial data on the second-generation BCR-ABL inhibitors, dasatinib and nilotinib, indicate a potentially greater efficacy than imatinib, but the improvement is likely to be modest. The overall efforts in terms of developmental therapeutics in ALL are very modest and not in keeping with the urgent need for improvement. Most agents being investigated have mechanisms of action similar to those of existing agents for ALL therapy and thus represent modest opportunities to improve results. Of such agents, data on BCR-ABL inhibitors, sphingosomal vincristine, pemetrexed, talotrexin, annamycin and ABT-751 are reviewed.

Abstract
Factors able to predict overall survival in adult patients with acute lymphoblastic leukaemia were assessed according to the period since initiation of the treatment using a Cox proportional hazards model. This period covers successively an initial period during the induction treatment and a consolidation period during the postinduction treatment. From 1994 to 2002, 922 patients with acute lymphoblastic leukaemia (excluding French-American-British L3 subtype) were enrolled in a multicentre protocol and followed, with a mean follow up of 58 months. A multivariate time-segmented analysis was performed on 658 patients. Analyses of the initial (before 100 d) and the late phases were realised after stratification on the type of induction treatment and on the different treatment strategies respectively. Age was the sole factor that influenced survival during the initial phase (hazard ratio 1.48 per 10-yr increase; P < 0.01). Factors that predicted survival during the late phase were age (hazard ratio 1.12, P = 0.02), white blood cells count (hazard ratio 1.01 per 10(10) cells/L increase; P < 0.05), lactic dehydrogenase level (hazard ratio 1.001 for 10 IU/L increase; P < 0.01) and t(9;22) karyotype or miscellaneous others vs. normal karyotype (hazard ratios 1.40; P < 0.01 and 1.06; P = 0.04 respectively). This analysis suggests that predictive factors may be split into tolerance factors and haematological factors. Determination of such factors is crucial to adapt postremission therapeutic strategies in acute lymphoblastic leukaemia.

Abstract
Although most patients with adult acute lymphoblastic leukaemia (ALL) can achieve a remission when treated with conventional, DNA-damaging chemotherapy, in more than half of all cases the disease relapses and ultimately results in death. Therefore, there is a substantial need for new antileukaemic drugs. Recent advances in the understanding of the molecular alterations in ALL have lead to the identification of new targets and the arrival of molecular-targeted therapies in the clinical setting. The prototype for this approach is the treatment of Philadelphia chromosome-positive ALL with imatinib mesylate. Here, the targeting of a molecular abnormality--inhibition of BCR-ABL tyrosine kinase--has turned a very poor-prognosis disease into one in which promising results are achieved. Promising new therapies are under development that target various goals, including the NOTCH signalling pathway, purine nucleoside phosphorylase activity, mammalian target of rapamycin and tyrosine kinase. This review outlines recent advances in the development of emerging drugs for the treatment of adult ALL. The recent advances in the understanding of the biology and pathogenesis of ALL have helped to determine prognosis and to plan the therapy of adult patients with ALL. Still, despite improved complete remission rates of 65-90% with current therapy, only 20-40% of patients can be considered cured. New therapeutic alternatives are needed to improve these results. With a better understanding of the disease, more target-specific therapies could be designed. The aim of this review is to highlight new pharmacotherapies and those emerging drug treatments for patients with adult ALL.

Abstract
Outcome of acute lymphoblastic leukemia (ALL) in adults with central nervous system (CNS) disease at diagnosis is unclear. We treated 1508 de novo ALL patients with 2-phase induction and then high-dose methotrexate with l-asparaginase. Patients up to 50 years old in first remission (CR1) with a matched related donor (MRD) underwent an allogeneic stem cell transplantation (SCT); the remainder in CR1 were randomized to an autologous SCT or intensive consolidation followed by maintenance chemotherapy. Philadelphia chromosome (Ph)-positive patients were offered a matched unrelated donor (MUD) allogeneic SCT. Seventy-seven of 1508 (5%) patients a median age of 29 years had CNS leukemia at presentation; 13 of the 77 (17%) had Ph-positive ALL. Sixty-nine of 77 (90%) patients attained CR1. Thirty-six patients underwent transplantation in CR1 (25 MRD, 5 MUD, and 6 autografts). Eleven of 25 patients with MRD transplantation remain alive at 21 to 102 months, 2 of 5 with MUD at 42 and 71 months, and 1 of 6 with autologous SCT at 35 months. Seven of 27 treated with consolidation/maintenance remain in CR1 56 to 137 months after diagnosis. Overall survival at 5 years was 29% in those with CNS involvement at diagnosis versus 38% (P = .03) for those without. CNS leukemia in adult ALL is uncommon at diagnosis. Adult Ph-negative ALL patients, however, can attain long-term disease-free survival using SCT as well as conventional chemotherapy.

Abstract
AbstractAdult patients with acute lymphoblastic leukemia (ALL) who are stratified into the standard-risk (SR) group due to the absence of adverse prognostic factors relapse in 40% to 55% of the cases. To identify complementary markers suitable for further treatment stratification in SR ALL, we evaluated the predictive value of minimal residual disease (MRD) and prospectively monitored MRD in 196 strictly defined SR ALL patients at up to 9 time points in the first year of treatment by quantitative polymerase chain reaction (PCR). Frequency of MRD positivity decreased from 88% during early induction to 13% at week 52. MRD was predictive for relapse at various follow-up time points. Combined MRD information from different time points allowed definition of 3 risk groups (P < .001): 10% of patients with a rapid MRD decline to lower than 10-4 or below detection limit at day 11 and day 24 were classified as low risk and had a 3-year relapse rate (RR) of 0%. A subset of 23% with an MRD of 10-4 or higher until week 16 formed the high-risk group, with a 3-year RR of 94% (95% confidence interval [CI] 83%-100%). The remaining patients whose RR was 47% (31%-63%) represented the intermediate-risk group. Thus, MRD quantification during treatment identified prognostic subgroups within the otherwise homogeneous SR ALL population who may benefit from individualized treatment.

Abstract
To evaluate the results of autologous stem cell transplantation (ASCT) in a large population of adults with acute lymphoblastic leukemia (ALL) in first complete remission (CR), we performed an individual data-based overview of the last three trials from the LALA group. Overall, 349 patients with ALL prospectively randomized in the consecutive LALA-85, -87, and -94 trials to receive either ASCT or chemotherapy as post-CR treatment were analyzed. Eligibility criteria were 15-50-year-old patients without sibling donors in both LALA-85/87 trials and 15-55-year-old patients with high-risk ALL and no sibling donors in the LALA-94 trial. Intent-to-treat analysis, which compared 175 patients from the ASCT arm to 174 patients from the chemotherapy arm, showed that ASCT was associated with a lower cumulative incidence of relapse (66 vs 78% at 10 years; P=0.05), without significant gain in disease-free or overall survival. Despite a possible lack of statistical power, a nested case-control analysis performed in 85 patient pairs adjusted for time to transplant and prognostic covariates confirmed these intent-to-treat results in patients actually transplanted. Of interest, the reduced relapse risk after ASCT translated in better disease-free survival in the 300 rapid responders who reached CR after the first induction course.

Abstract
Acute lymphoblastic leukaemia (ALL) in adults is a relatively rare neoplasm with a curability rate around 30% at 5 years. This consideration makes it imperative to dissect further the biological mechanisms of disease, in order to selectively implement an hitherto unsatisfactory success rate. The recognition of discrete ALL subtypes (some of which deserve specific therapeutic approaches, like T-lineage ALL (T-ALL) and mature B-lineage ALL (B-ALL)) is possible through an accurate combination of cytomorphology, immunophenotytpe and cytogenetic assays and has been a major result of clinical research studies conducted over the past 20 years. Two-three major prognostic groups are now easily identifiable, with a survival probability ranging from <10 to 20% (Philadelphia-positive ALL) to about 50-60% (low-risk T-ALL and selected patients with B-lineage ALL). These issues are extensively reviewed and form the basis of current knowledge. The second major point relates to the emerging importance of studies that reveal a dysregulated gene activity and its clinical counterpart. It is now clear that prognostication is a complex matter ranging from patient-related issues to cytogenetics to molecular biology, including the evaluation of minimal residual disease (MRD) and possibly gene array tests. On these bases, the role of a correct, highly personalised therapeutic choice will soon become fundamental. Therapeutic progress may be obtainable through a careful integration of chemotherapy, stem cell transplantation, and the new targeted treatments with highly specific metabolic inhibitors and humanised monoclonal antibodies.

Abstract
PURPOSE We analyzed the benefits of a risk-adapted postremission strategy in adult lymphoblastic leukemia (ALL), and re-evaluated stem-cell transplantation (SCT) for high-risk ALL. PATIENTS AND METHODS A total of 922 adult patients entered onto the trial according to risk groups: standard-risk ALL (group 1), high-risk ALL (group 2), Philadelphia chromosome-positive ALL (group 3), and CNS-positive ALL (group 4). All received a standard four-drug/4-week induction course. Patients from group 1 who achieved a complete remission (CR) after one course of induction therapy were randomly assigned between intensive and less intensive postremission chemotherapy, whereas those who achieved CR after salvage therapy were then included in group 2. Patients in groups 2, 3, and 4 with an HLA-identical sibling were assigned to allogeneic SCT. In groups 3 and 4, autologous SCT was offered to all other patients, whereas in group 2 they were randomly assigned between chemotherapy and autologous SCT. RESULTS Overall, 771 patients achieved CR (84%). Median disease-free survival (DFS) was 17.5 months, with 3-year DFS at 37%. In group 1, the 3-year DFS rate was 41%, with no difference between arms of postremission randomization. In groups 2 and 4, the 3-year DFS rates were 38% and 44%, respectively. In group 2, autologous SCT and chemotherapy resulted in comparable median DFS. Patients with an HLA-matched sibling (groups 2 and 4) had improved DFS. Three-year DFS was 24% in group 3. CONCLUSION Allogeneic SCT improved DFS in high-risk ALL in the first CR. Autologous SCT did not confer a significant benefit over chemotherapy for high-risk ALL.

Abstract
Orthotopic liver transplantation (OLT) is potentially curative for patients with early stage hepatocellular carcinoma (HCC). However, tumor progression before OLT remains a problem. Ninety-three patients were listed for transplantation with HCC or diagnosed with HCC following listing between March, 1997 and September, 2001. Modified TNM Stage was I/II in 82 patients and III in 11 patients. Seventy-one patients (76%) were transplanted with a median waiting time of 3.4 months, and 22 (24%) patients were delisted owing to tumor progression (14), noncompliance (5), and death from liver failure (3). Using a cox model competing risks approach, higher baseline alpha-fetoprotein (AFP) >or= 100 ng/mL was the only factor independently associated with a higher hazard rate of delisting owing to tumor progression (p = 0.00003), whereas four separate factors were independently associated with a lower hazard rate of transplantation: more recent listing year (1999-2001, p = 0.010), blood type O (p = 0.013), Stage I HCC (p = 0.029), and serum bilirubin < 4 mg/dL (p = 0.032). By logistic regression, AFP >/= 100 ng/mL was the only factor that significantly influenced the probability of delisting owing to tumor progression (p = 0.001). In conclusion, the initial AFP level may be useful along with tumor stage in defining an urgency score for liver transplant candidates with HCC.

Abstract
OBJECTIVE The rationale for this retrospective study was to identify the long-term overall and event-free survival, relapse, and treatment-related mortality rates of high-risk pediatric and adult first (CR1) and second remission (CR2) patients with acute lymphoblastic leukemia (ALL) who were treated with a single preparatory regimen consisting of fractionated total-body irradiation (FTBI) and high-dose etoposide (VP-16) prior to allogeneic hematopoietic cell transplantation. PATIENTS AND METHODS Over a 15-year period at Stanford University Medical Center, 85 consecutive high-risk pediatric (up to age 17 years; n=41) and adult (age 18-55 years; n=44); patients with leukemia (ALL) in CR1 (n=55) and CR2 (n=30) received HLA-matched sibling allogeneic bone marrow or peripheral blood progenitor grafts after being treated with FTBI (1320 cGy) and high-dose VP-16 (60 mg/kg) as their preparatory regimen. The majority of patients transplanted in CR1 (n=45) had high-risk features, including age above 30 years, white blood cell count at presentation exceeding 25000/microL, extramedullary disease, need for more than 4 weeks of induction chemotherapy to achieve CR, or high-risk chromosomal translocations. Most patients transplanted in CR1 were adults (n=39), whereas patients in CR2 were primarily children or adolescents (n=25). RESULTS The 10-year Kaplan-Meier estimates of relapse were significantly (p=0.05) lower in CR1 patients (15%+/-10%) than in CR2 patients (33%+/-20%). Relapse was the most common cause of treatment failure in patients transplanted in CR2. There was a significantly (p=0.05) higher rate of chronic graft-vs-host disease in CR1 (32%+/-14%) compared with CR2 (9%+/-11%) patients; however, overall survival for patients transplanted in CR1 (66%+/-14%) was comparable (p=0.67) to that of patients transplanted in CR2 (62%+/-19%). Event-free survival rates also were similar (p=0.53) between CR1 (64%+/-14%) and CR2 (61%+/-18%) patients. Treatment-related mortality rates were equivalent (p=0.51) between CR1 and CR2, as well as between Philadelphia chromosome (Ph) positive (Ph(+))and Ph(-) (p=0.23) ALL patients. CONCLUSION Overall, FTBI/VP-16 is a highly effective preparatory regimen that provides durable remissions for patients receiving allogeneic hematopoietic cell transplantation for high-risk ALL in CR1 or CR2.

Abstract
The prognosis of patients with acute lymphoblastic leukemia (ALL), treated with modern chemotherapeutic regimens, is dependent on a number of variables. The major prognostic factors for survival in adult ALL are age, cytogenetic abnormalities, immunologic subtype, white blood cell (WBC) count, and time to achieve complete remission (CR). Determination of these factors is crucial for adapting post remission therapy in adult ALL. Indeed, risk-adapted strategies based on those biologic and clinical features are currently being applied to improve survival. In this review, we report the different prognostic factors described in adult ALL and discuss the controversies in current adult ALL management in relation with these different features. The data reported are derived from the medical literature and from the experience of the authors. Prognostic factors appear to be time-dependent. This emphasizes their determination according to the phase of treatment. The use of time-segmented multivariate analysis able to distinguish prognostic factors associated with the induction phase and those associated with the post-induction phase of treatment seems suitable to define accurately prognostic models.

Abstract
The chronological history of the important discoveries leading to our present understanding of the essential clinical, biological, biochemical, and molecular features of chronic myelogenous leukemia (CML) are first reviewed, focusing in particular on abnormalities that are responsible for the massive myeloid expansion. CML is an excellent target for the development of selective treatment because of its highly consistent genetic abnormality and qualitatively different fusion gene product, p210(bcr-abl). It is likely that the multiple signaling pathways dysregulated by p210(bcr-abl) are sufficient to explain all the initial manifestations of the chronic phase of the disease, although understanding of the circuitry is still very incomplete. Evidence is presented that the signaling pathways that are constitutively activated in CML stem cells and primitive progenitors cooperate with cytokines to increase the proportion of stem cells that are activated and thereby increase recruitment into the committed progenitor cell pool, and that this increased activation is probably the primary cause of the massive myeloid expansion in CML. The cooperative interactions between Bcr-Abl and cytokine-activated pathways interfere with the synergistic interactions between multiple cytokines that are normally required for the activation of stem cells, while at the same time causing numerous subtle biochemical and functional abnormalities in the later progenitors and precursor cells. The committed CML progenitors have discordant maturation and reduced proliferative capacity compared to normal committed progenitors, and like them, are destined to die after a limited number of divisions. Thus, the primary goal of any curative strategy must be to eliminate all Philadelphia positive (Ph+) primitive cells that are capable of symmetric division and thereby able to expand the Ph+ stem cell pool and recreate the disease. Several highly potent and moderately selective inhibitors of Bcr-Abl kinase have recently been discovered that are capable of killing the majority of actively proliferating early CML progenitors with minimal effects on normal progenitors. However, like their normal counterparts, most of the CML primitive stem cells are quiescent at any given time and are relatively invulnerable to the Bcr-Abl kinase inhibitors as well as other drugs. We propose that survival of dormant Ph+ stem cells may be the most important reason for the inability to cure the disease during initial treatment, while resistance to the inhibitors and other drugs becomes increasingly important later. An outline of a possible curative strategy is presented that attempts to take advantage of the subtle differences in the proliferative behavior of normal and Ph+ stem cells and the newly discovered selective inhibitors of Bcr-Abl.

Abstract
Myeloid/natural killer (NK) cell precursor acute leukemia is an entity of acute leukemia characterized by poor prognosis and a CD7+CD56+ myeloid antigen+ phenotype without light-microscopic myeloperoxidase reactivity. This disease shares several clinical characteristics with acute myeloid leukemia (AML) M0. To clarify the relationship between these 2 leukemias, we analyzed 105 cases of AML M0. Among them, 17 were CD7+ and CD56+, 77 were negative for either antigen, and 11 could not be determined. CD7+CD56+ AML M0 showed onset at significantly lower patient age (median 46 versus 63 years, P = .004). The disease localization and the hematological manifestations were significantly different: CD7+CD56+ AML showed more frequent extramedullary involvement, fewer circulating leukemic blasts, less anemia, and less thrombocytopenia than did AML M0. The cytogenetic aberrations were also unique, because no 5q abnormalities were found in CD7+CD56+ M0. The prognosis of CD7+CD56+ M0 was poor in patients younger than 46 years (P = .03). Multivariate analysis showed that the CD7+CD56+ phenotype was a significant prognostic factor for AML M0, as well as age, circulating blast percentage, and chromosome 5 abnormalities These findings suggest that AML M0 consists of heterogeneous subgroups to be managed separately, and CD7+CD56+ M0 constitutes a distinct subtype of AML M0.

Abstract
BACKGROUND Because of the relative paucity of data regarding the clinical outcome in adult patients with acute lymphocytic leukemia (ALL) in Korea, we analyzed clinical courses in adult ALL patients treated with VPD (L) regimen (vincristine, prednisolone, daunorubicin, L-asparaginase) at the Seoul National University Hospital, and evaluated prognostic factors influencing the outcome. METHODS Patients with ALL newly diagnosed between October 1994 and June 2000 at our hospital were analyzed retrospectively. Fifty-three patients were evaluable. Induction chemotherapy consisted of VPD with (46 cases) or without L-asparaginase (7 cases). After complete remission (CR), consolidation therapy, CNS prophylaxis and maintenance chemotherapy were administered. RESULTS Ages ranged from 16 to 67 (median 30). CR rate was 86.8% (46/53) and no significant prognostic factor was found for the CR rate. With a median follow-up time of 27.2 months (range 12.9-83.0 months) in living patients, the median overall survival (OS) for all cases was 16.7 months (13.4-20.1 months, 95% C.I.) and the estimated 4-year OS rate was 25.4% +/- 8.9%. The median relapse-free survival (RFS) was 12.2 months (8.4-16.0 months, 95% C.I.), and 3-year RFS rate was 29.9% +/- 10.2%. Poor prognostic factors for OS were Ph chromosome (p = 0.005) and T-cell immunophenotype (p = 0.03). For RFS they were Ph chromosome (p = 0.01) and the presence of a mediastinal mass (p = 0.03). CONCLUSION Despite an initial excellent response to the VPD (L) regimen, newer therapeutic strategies, including more intensive postremission therapies, are urgently needed because of the high relapse rate. Future therapeutic approaches need to be stratified according to several prognostic factors.

Abstract
The prognosis for adult acute lymphoblastic leukaemia (ALL) is poor. Only 20-30% of patients will be cured with conventional chemotherapy. Haematopoietic progenitor transplantation is thus an attractive option in these patients. Even if allogeneic transplantation allows a better control of the disease, autologous transplantation remains an important alternative for patients lacking a suitable donor or when allogeneic transplants imply excessive risk. Relapse is the main drawback of autologous transplants, but many strategies are being explored to overcome this problem. We focus here on transplant modality, the source of haematopoietic progenitors, and the best timing to apply the procedure. Also reviewed are the current situation and future strategies for improving results in this setting, such as ex vivo purging; immunotherapy and maintenance chemotherapy.

Abstract
From 1986 to 1998, 26 (23%) of 114 adult acute lymphoblastic leukemia (ALL) patients and 11 (4%) of 328 pediatric patients were found to have Philadelphia (Ph) chromosome. In the 30 patients with available data at diagnosis, 18 (60%) had extra-chromosomal abnormalities. They included 1q duplication (5/18, 28%), supernumerary Ph chromosome (4/18, 22%), 9p abnormalities (3/18, 17%), 7q deletion/monosomy 7 (3/18, 17%), trisomy 19 (1/18, 6%), and trisomy 8 (1/18, 6%). Excluding those with specific cytogenetic changes, only one patient had hyperdiploid karyotype with more than 50 chromosomes. The incidence of 1q duplication was higher and that of hyperdiploidy was lower in this study than has been previously reported. There was no prognostic implication of these additional cytogenetic abnormalities. With fluorescence in situ hybridization (FISH) and reverse transcription-polymerase chain reaction (RT-PCR), 14 (27%) of 53 unselected adult ALL patients and 2 (5%) of 38 unselected pediatric patients were BCR-ABL-positive, including one adult and two children without Ph chromosome. The BCR-ABL fusion genes/transcripts were also present in all other 16 selected Ph-positive ALL patients. The BCR-ABL fusion subtypes were determined in all these 32 patients: 91% (11/12) childhood cases showed m-type fusion gene while 45% (9/20) adult ones did so (P = 0.0083). The clinical outcome was similar between the two groups of patients with m-type and M-type BCR-ABL. In conclusion, both cytogenetic and molecular studies are very helpful for identifying the subgroup of ALL patients with Ph/BCR-ABL. The additional cytogenetic abnormalities and subtypes of BCR-ABL fusion genes/transcripts had no significant implications in this group of patients.

Abstract
Less than 40% of adult acute lymphocytic leukaemia (ALL) patients will still be alive at 5 years post-diagnosis. Ways to improve patients' outcome, using high-dose therapy followed by autologous/allogeneic stem cell transplantation (SCT) in first complete remission (CR1) rather than consolidation/maintenance chemotherapy, have been investigated. However, prospective studies are small and results are inconclusive. The largest prospective trial ever being performed in adult ALL patients, the ongoing UKALL 12/ECOG 2993 trial, is assigning all patients who have a sibling donor to receive allogeneic SCT (alloSCT) in CR1, whereas all other patients are randomized to continue chemotherapy versus autologous SCT. An interim analysis of this trial seems to support an alloSCT in first CR in adult ALL patients (reflected by a significantly reduced relapse rate with an improved disease-free survival). However, less than 30% of the patients have a matched sibling donor, the majority of the patients are over 40 years old, which makes them less suitable for conventional allograft, and even in those who have a matched sibling donor and are young and fit enough to receive it the treatment-related mortality (TRM) is about 20%. Strategies for expanding donor availability, meanwhile, to reduce the TRM, remain challenges. Data regarding the efficacy of reduced-intensity regimens in ALL patients are still scanty. Another way of improving patient outcome is to select patients for allograft more carefully. There are enough data to suggest now that children who achieved a clinical remission but failed to obtain a molecular/immunological remission are more prone to relapse. Similar data have recently been published for adult ALL. However, data are still limited, and the significance of minimal residual disease (MRD) has never been studied prospectively in adult ALL patients. A reasonable approach is to assign all patients with a matched related donor who has failed to achieve a molecular/immunological remission to receive a conventional alloSCT, whereas all others might be randomized to receive alloSCT versus chemotherapy/autologousSCT. However, patients with Ph(+) ALL who have a donor should receive an alloSCT in CR1, regardless of their MRD results. It appears that alloSCT provides the best chance for cure. However, by improving our ability to select those who have the highest risk for relapse, unnecessary toxicity/mortality might be prevented and the general outcome might improve.

Abstract
Bone marrow (BM) sections were examined in 128 untreated adult patients with newly diagnosed acute lymphoblastic leukemia (ALL), seen in our institution over a 19-year period. BM biopsy was performed in order to assess the incidence, degree and prognostic significance of histological data of the disease. BM features studied were reticular fibrosis, total cellularity, residual hematopoiesis, mitotic activity, and blastic infiltration. T-cell lineage ALL were diagnosed in 23% of the cases, while B-cell lineage ALL represented 70% of the cases. There were 7% of non-T-non-B-cell lineage ALL. The percentage of BM leukemic cells was related to cellularity (P=0.02), while it was related to the disappearance of normal cell lines (P<0.0001). BM cellularity was related to the percentage of circulating leukemic cells at diagnosis (P=0.006). Residual hematopoiesis was related to a higher initial granulocyte count (P=0.04) and lower percentage of circulating blasts (P=0.04). The degree of fibrosis was inversely related to that of BM cellularity (P=0.04). All patients, but four, received standard ALL induction chemotherapy according to different successive protocols. In this whole cohort of patients, complete remission (CR) rate was 78%. Median disease-free survival (DFS) and median overall survival (OS) were 13.7 months and 20.2 months, respectively. In univariate analysis, CR rate was positively affected by mitotic activity (P=0.01) and residual hematopoiesis (P=0.008). OS was positively influenced by a higher leukemic cell mitotic activity (P=0.03) and the persistence of more than two residual normal cell lines in BM (P=0.04). Patients presenting with both of those characteristics had better outcome than patients who did not, as well as, in terms of CR (P=0.03), or DFS (P=0.002), or OS (P=0.003). T-cell lineage ALL and L3 ALL did not significantly influence those results. Our findings did not confirm that among marrow features, reticular fibrosis has any prognostic value. A multivariate analysis of both clinical and histological data was performed to test their prognostic relevance. In a model including age, immunophenotype, Philadelphia chromosome status, mitotic index, and level of normal residual hematopoiesis, the only significant predictor of CR achievement were the persistence of normal residual hematopoietic cell lines (P=0.01) and the mitotic activity of leukemic cells (P=0.002). Philadelphia chromosome status (P=0.03) and age (P<0.0001) were of prognostic value, respectively for DFS and OS. We conclude that some characteristics of BM biopsy afford not only descriptive but also prognostic information for predicting the outcome. The persistence of normal residual hematopoiesis and intense leukemic cells mitotic activity were both factors of favorable outcome, while BM fibrosis did not display any prognostic value.

Abstract
PURPOSE To assess the efficacy and toxicity of a new treatment program of intensified and shortened cyclical chemotherapy (protocol 8707) in adults with acute lymphoblastic leukemia (ALL). PATIENTS AND METHODS Previously untreated adults < or = 60 years old with ALL were treated with a four-agent induction chemotherapy regimen. This was followed by cyclical postremission therapy with high-dose cytarabine/etoposide; high-dose methotrexate/6-mercaptopurine; and daunorubicin, vincristine, prednisone, and asparaginase. Maintenance chemotherapy with oral methotrexate and 6-mercaptopurine was continued for 30 months. CNS prophylaxis was given with intrathecal methotrexate in addition to the systemic chemotherapy indicated above. RESULTS Seventy-eight of 84 patients (93%) achieved complete remission. With a median follow-up of 5.6 years, 5-year event-free survival (EFS) of all remission patients is 52%. Patients with high-risk features including adverse cytogenetics, failure to achieve remission with the first cycle of chemotherapy, and B-precursor disease with WBC counts more than 100,000/microL all relapsed unless taken off study for transplantation. For patients without these high-risk features, 5-year EFS was 60%. Compared with our previous treatment regimen, results appear to be improved for patients with standard-risk B-precursor disease (5-year EFS, 66% v 34%; P =.01). CONCLUSION Intensified and shortened chemotherapy may improve the outcome for patients with ALL with B-precursor disease lacking high-risk features. Further trials of this regimen are warranted.

Abstract
The GIMEMA ALL 0288 trial was designed to evaluate the impact of a 7-day prednisone (PDN) pretreatment on complete remission (CR) achievement and length, the influence of the addition of cyclophosphamide (random I) to a conventional 4-drug induction on CR rate and duration, and whether an early post-CR intensification (random II) by an 8-drug consolidation could improve CR duration. Median follow-up of this study was 7.3 years. From January 1988 to April 1994, among 794 adult (> 12 but < 60 years) patients registered, 778 were eligible. Their median age was 27.5 years; 73% had B-lineage acute lymphoblastic leukemia (ALL) and 22% had T-lineage disease; 18% showed associated myeloid markers; 47 of 216 analyzed patients (22%) had Philadelphia chromosome-positive ALL. Response to PDN pretreatment was observed in 65% of cases. CR was achieved in 627 patients (82%). Resistant patients and induction death rates were 11% and 7%, respectively. Random II was applied to 388 patients with CR; 201 had maintenance alone and 187 had consolidation followed by maintenance. The relapse rate was 60%; isolated central nervous system relapses were 8% of all CRs and 13% of all relapses. Median survival (overall survival [OS]), continuous complete remission (CCR), and disease-free survival (DFS) were 2.2, 2.4, and 2 years, respectively. PDN pretreatment response resulted the main independent factor influencing CR achievement, OS, CCR, and DFS; the addition of cyclophosphamide in induction significantly influenced CR achievement in a multivariate analysis. Neither induction intensification nor early consolidation appeared to influence CCR and DFS duration. For the first time PDN pretreatment response proved to be a powerful factor predicting disease outcome in adult ALL patients.

Abstract
In an attempt to develop a new intensive chemotherapy for adults with untreated acute lymphoblastic leukemia (ALL), 3 sequential programs were designed for 62 patients (age range, 15 to 74 years; median age, 32 years) consisting of the LVP-79 (1979-1984, 27 patients), LVP-85 (1984-1986, 14 patients), and LVP-87 (1987-1989, 21 patients) regimens. The influence of clinical and biologic characteristics on the patient outcome was also examined. L-asparaginase (L-asp), vincristine, and prednisolone, defined collectively as LVP, were administered for induction chemotherapy in all protocols. After achieving complete remission (CR), patients underwent 2 years of multi-agent consolidation, intensification, and maintenance therapy consisting of various combinations. No significant differences were noted between the 3 groups regarding CR rate or survival. In total, 47 of 62 patients (75.8%) achieved CR. The median overall survival (OS) and median CR durations were 550 days and 341 days, respectively. Overall, the estimated survival rate at 20 years was 18.1%. The disease-free survival rate at 20 years was 26.2%. According to univariate analysis, the most favorable pretreatment characteristic for achieving CR was age. A younger age (<40 years of age), platelet count >30 x 10(9)/L, having L1 morphology (French-American-British [FAB]classification subtype), female sex, and the absence of chromosomal abnormalities also helped improve survival rate. According to multivariate analysis, presence of Ph chromosome was found to be a major influencing factor for OS. Although higher doses of L-asp were administered than those used in previous studies, the adverse effect of L-asp was rarely identified. Therefore, it should be considered one of the key drugs for treatment of adult ALL. Further strategies still need to be developed to obtain better survival in adult ALL.

Abstract
Data on all patients with acute lymphoblastic leukemia (ALL) aged 60 or older, referred to our institution over a 18-year period, were studied to determine the incidence and range of clinical and biological subtypes, and the outcome of different therapeutic approaches. Sixty-nine ALL cases (median age: 68 years) were diagnosed between 1980 and 1998 (18% of all adult ALL seen during this period). Ten of them (14%) had a past history of previous malignancy. Karyotypic analysis was performed successfully in 42 cases. Ten patients were diagnosed as Philadelphia chromosome positive (Ph(+)) ALL. Immunophenotyping was performed in 63 cases. Fifty-six patients had B-cell lineage ALL. T lymphoid markers were observed only in 5 cases. Co-expression of myeloid markers was observed in 19% of tested cases. Five patients died before any chemotherapy could be given. All other patients received "curative" treatment according to different protocols used during the period of study. Overall complete remission (CR) rate of these patients was 62% (95% confidence interval (CI): 50-74%). Thirty-nine patients achieved CR after one course of chemotherapy and 4 patients after salvage therapy. Median disease-free survival (DFS) of the entire cohort was 8.3 months (95% CI: 5-12.8 months) and median overall survival was 7 months (95% CI: 6-10 months). In multivariate analysis, the presence of hemorrhage (P = 0.02) was a poor prognostic for CR achievement. Higher WHO performance status (P = 0.003) and the presence of hemorrhage (P = 0.01) at diagnosis were poor prognostics for overall survival. When patients were stratified into three groups according to the time of admission, survival appeared significantly longer for patients admitted between July 1992 and December 1998 (median overall survival at 10 months) than for patients admitted before July 1992 (P = 0.04). "Age-adapted" therapy appeared superior to "young adult-like" therapy in terms of CR rate (96% versus 60%; P = 0.007). However, "age-adapted" therapy did not show any advantage in terms of DFS or overall survival, making the difference in CR rates questionable. We conclude that the pejorative overall outcome in elderly ALL points to the need for new therapeutic trials taking into account the specific characteristics of ALL in this age group.

Abstract
The effectiveness of intensive post-remission chemotherapy regimens for adult patients with acute lymphoblastic leukemia (ALL) is limited by both a high rate of disease recurrence and a substantial incidence of treatment toxicity. To evaluate a potentially more effective and less toxic approach, we conducted a multicenter phase III trial of consolidation therapies comparing the standard L10M regimen with one combining the brief, intensive L17M regimen and escalating methotrexate (MTX) and L-asparaginase (L-asp). Patients over age 15 with previously untreated ALL were eligible. Induction therapy included vincristine, prednisone, doxorubicin, cyclophosphamide and intrathecal methotrexate administered over 36 days. Patients who achieved complete remission (CR) were randomized to receive consolidation with either the L10M regimen or with DAT (daunomycin, cytosine arabinoside, 6-thioguanine) and escalating MTX and L-asp. The randomization was stratified by age, WBC and Ph chromosome status. Maintenance therapy was the same in both arms. Of 353 eligible patients, 218 (62%) achieved CR and 195 were randomized. The treatment arms did not differ significantly with respect to disease-free survival (DFS; P= 0.46) or overall survival (P= 0.39). Estimated DFS at 5 years was 32% (95% confidence interval (CI) 23-42%) in the L10M arm and 25% (95% CI 16-33%) in the DAT/MTX/L-asp arm. In each arm, 4% of patients died of toxicities (infection in all but one case). Infections and nausea/vomiting were somewhat more common in the L10M arm (occurring in 68% and 53% of patients respectively) than the DAT/MTX/L-asp arm (56% and 33%). The DAT/MTX/L-asp consolidation regimen was associated with some reduction in nonfatal toxicities, but no significant improvement in DFS, overall survival or non-relapse mortality when compared to the standard L10M regimen.

Abstract
The overall prognosis for patients with relapsed or refractory adult ALL remains poor. Further insight into the biology of ALL is required, and novel therapeutic agents are needed to counter mechanisms of resistance. A palliative approach to the management of multiply relapsed or refractory ALL should be supplanted by enrollment into clinic trials to promote drug discovery. Monitoring of minimal residual disease may allow an earlier intervention before overt clinical relapse and improve outcome; prospective studies are needed. Attainment of a second or later CR should be followed by allogeneic BMT when feasible owing to the paucity of long-term survivors with salvage chemotherapy alone.

In the last 30 years, a multitude of treatment regimens for adult acute lymphocytic leukemia (ALL) has been developed. Essentially, all of these regimens use an induction therapy vincristine, prednisone, and an anthracycline intensified with L-asparaginase or cyclophosphamide. Though such regimens induce most patients to enter a remission, relapse is frequent, and most adult patients ultimately die of their disease. The author postulated that further refinements in this approach to induction therapy were unlikely to markedly improve treatment results in this disease. Therefore, the author is studying a new intensive strategy using cytarabine with a single very high dose of mitoxantrone (without vincristine or prednisone) as induction therapy for adult patients with ALL.

Abstract
The regimen of hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone (hyper-CVAD) has demonstrated significant activity in adult lymphocytic leukemia (ALL) and in other hematologic malignancies, including Burkitt's disease, lymphoblastic lymphoma, mantle cell lymphoma, and multiple myeloma. This article presents the rationale for the development of this regimen, describes the program, summarizes the results of the large clinical trials developed at the University of Texas M. D. Anderson Cancer Center, and discusses strategies to improve the results.
