Abstract
During the last decade, increasing attention has been paid to a unique group of patients with acute lymphoblastic leukemia (ALL) who lie at the crossroad of therapeutic care by pediatric and adult hematologists/oncologists. ALL is a disease that affects infants, children, adolescents, and adult patients. With current therapies, the vast majority of children with ALL are now long-term survivors; unfortunately, the same good results have not yet been obtained for adults with ALL. This review will describe current controversies surrounding the treatment of adolescents and young adults with ALL—a group who finds themselves in the transition from “pediatric” to “adult” treatment approaches. The review focuses on recent insights into disease biology, prognostic factors, and treatment outcomes that have led to a series of prospective clinical trials specifically designed for adolescents and younger adults (AYAs) with ALL. These trials have been designed to provide important new clinical, psychosocial, and biological insights, and to further improve the survival of this challenging and unique group of patients.

Abstract
Age-related differences in the distribution, biology and treatment response of non-Hodgkin's lymphoma (NHL) in adolescents remain to be elucidated. The current analyses present clinical parameters and outcomes of adolescents treated in pediatric NHL-BFM trials. Patients were stratified by histological subtype: lymphoblastic lymphoma (LBL); mature B-NHL, including Burkitt's lymphoma/leukemia (BL/B-AL), diffuse B-cell lymphoma (DLBCL-CB) and mediastinal B-cell lymphoma (PMLBL); and anaplastic large cell lymphoma (ALCL). Between October 1986 and December 2007, 2915 patients were registered, including 378 (13%) adolescents (15-18 years) with BL/B-AL (n=101), ALCL (n=74), DLBCL-CB (n=55), T-LBL (n=45), PMLBL (n=24), pB-LBL (n=13) and rare or not-specified NHL subtypes (n=66). The 5-year event-free survival (EFS) was 79±2% for adolescents compared with 85±1% for patients aged <15 years (P=0.014). EFS was 83±7% for adolescents with T-LBL, 82±4% with BL/B-AL, 85±5% with DLBCL-CB, 57±10% with PMLBL and 70±6% with ALCL. According to sex, the 5-year EFS in females versus males, respectively, was 70±5 versus 83±2% overall (P=0.004), 57±17 versus 92±6% (P=0.0036) for T-LBL patients and 71±9 versus 97±3% (P=0.0067) for DLBCL-CB patients. Adolescents with NHL treated according to pediatric NHL-BFM protocols had an EFS of 79±2%, which is marginally inferior to that of children. In adolescents with T-LBL and DLBCL-CB, female sex was associated with a worse prognosis.

Abstract
Asparaginases are a cornerstone of treatment protocols for acute lymphoblastic leukemia (ALL) and are used for remission induction and intensification treatment in all pediatric regimens and in the majority of adult treatment protocols. Extensive clinical data have shown that intensive asparaginase treatment improves clinical outcomes in childhood ALL. Three asparaginase preparations are available: the native asparaginase derived from Escherichia coli (E. coli asparaginase), a pegylated form of this enzyme (PEG-asparaginase), and a product isolated from Erwinia chrysanthemi, ie, Erwinia asparaginase. Clinical hypersensitivity reactions and silent inactivation due to antibodies against E. coli asparaginase, lead to inactivation of E. coli asparaginase in up to 60% of cases. Current treatment protocols include E. coli asparaginase or PEG-asparaginase for first-line treatment of ALL. Typically, patients exhibiting sensitivity to one formulation of asparaginase are switched to another to ensure they receive the most efficacious treatment regimen possible. Erwinia asparaginase is used as a second- or third-line treatment in European and US protocols. Despite the universal inclusion of asparaginase in such treatment protocols, debate on the optimal formulation and dosage of these agents continues. This article provides an overview of available evidence for optimal use of Erwinia asparaginase in the treatment of ALL.

Abstract
Acute lymphoblastic leukemia affects infants, children, adolescents, and adults. Although most children have a high likelihood of cure, outcomes in adults have much room for improvement. In between lies the adolescent and young adult population, not only in terms of age but also in clinical success rates. This review describes biology, prognostic factors, and treatment approaches in adolescents and young adults with acute lymphoblastic leukemia. Assessing the outcomes in adult and pediatric clinical trials that enroll adolescents and young adults can be especially useful in determining how best to treat these patients. Current new treatment strategies are also discussed.

Abstract
The last 30 years have seen significant improvements in survival rates for children and older adults. In contrast, the 5-year survival rate among 20 to 39 year olds has been static at around 70% since 1986. Data from the United States, Australia, Italy, and the United Kingdom suggest that this age group also has the lowest rate of clinical trial participation. In the United States, just 2% of patients aged 20 to 29 years enter trials, in contrast with an estimated 60% of patients under 15 years of age. In the United Kingdom, the nadir in accrual is for patients aged 35 to 39 years, of whom only 7.5% are recruited, compared to 52.7% of patients below 15 years of age. This level of trial activity may be associated with the lack of improvement in survival for the older age group. Strategies to increase the numbers of adolescents and young adults (AYA) recruited to cancer clinical trials have become a focus of research activity in several countries. This article explores possible barriers to recruitment of AYA and summarizes current policies in the United States and the United Kingdom to increase accrual of young adults with cancer to clinical trials.

Abstract
Acute lymphoblastic leukemia (ALL), a clonal expansion of hematopoietic blasts, is a highly heterogeneous disease comprising many entities for which distinct treatment strategies are pursued. Although ALL is a success story in pediatric oncology, results in adults lag behind those in children. An expansion of new drugs, more reliable immunologic and molecular techniques for the assessment of minimal residual disease, and efforts at more precise risk stratification are generating new aspects of adult ALL therapy. For this review, the authors summarized pertinent and recent literature on ALL biology and therapy, and they discuss current strategies and potential implications of novel approaches to the management of adult ALL.

Abstract
The Children's Cancer Group enrolled 13 298 young people age <21 years on 1 of 16 protocols between 1983 and 2002. Outcomes were examined in three time periods, 1983-1988, 1989-1995, 1996-2002. Over the three intervals, 10-year event-free survival (EFS) for Rome/National Cancer Institute standard risk (SR) and higher risk (HR) B-precursor patients was 68 and 58%, 77 and 63%, and 78 and 67%, respectively, whereas for SR and HR T-cell patients, EFS was 65 and 56%, 78 and 68%, and 70 and 72%, respectively. Five-year EFS for infants was 36, 38, and 43%, respectively. Seminal randomized studies led to a number of important findings. Stronger post-induction intensification improved outcome for both SR and HR patients. With improved systemic therapy, additional intrathecal (IT) methotrexate effectively replaced cranial radiation. For SR patients receiving three-drug induction, iso-toxic substitution of dexamethasone for prednisone improved EFS. Pegylated asparaginase safely and effectively replaced native asparaginase. Thus, rational therapy modifications yielded better outcomes for both SR and HR patients. These trials provide the platforms for current Children's Oncology Group trials.

Abstract
PURPOSE Data from the State of Georgia suggest that pediatric cancers have better survival outcomes when treated at pediatric cancer centers that are members of the nation's Children's Oncology Group (COG). PATIENTS AND METHODS To determine if the more adult types of cancer that occur in adolescents are better treated at centers with adult oncology expertise, the reported data were re-analyzed according to a scale that assessed whether the type of cancer was more likely to have been treated by oncologists with pediatric versus adult cancer experience. RESULTS The results showed that survival hazard index was linearly correlated in 15- to 19-year-olds with the pediatric versus adult cancer type index (P < 0.0001). All of the five most pediatric type of cancers had a better survival at COG institutions and all of the three tumors with a better survival at non-COG institutions had the highest adult type scores. CONCLUSION These results demonstrate that adolescent patients with pediatric types of cancer fare better when their care is conducted or supervised by oncologists who specialize in the care of their type of cancer. The Georgia data are among the first to indicate that the more adult type of cancers are better treated on an adult treatment regimen and/or under the supervision or in conjunction with adult-treating oncologists.

Abstract
AbstractChromosomal abnormalities are increasingly used to risk stratify adults with acute lymphoblastic leukemia. Published data describing the age-specific incidence of chromosomal abnormalities and their prognostic relevance are largely derived from clinical trials. Trials frequently have age restrictions and low recruitment rates. Thus we investigated these factors in a population-based cohort of 349 patients diagnosed during the course of 19 years in the northern part of England. The incidence of most chromosomal abnormalities varied significantly with age. The incidence of t(9;22)(q34;q11) increased in each successive decade, up to 24% among 40- to 49-year-old subjects. Thereafter the incidence reached a plateau. t(4;11)(q21;q23) and t(1;19)(q23;p13) were a rare occurrence among patients older than 60 years of age. In contrast, the frequency of t(8;14)(q24;q32) and t(14;18)(q32;q21) increased with age. High hyperdiploidy occurred in 13% of patients younger than 20 years of age but in only 5% of older patients. The incidence of low hypodiploidy/near-triploidy and complex karyotype increased with age from 4% (15-29 years) to 16% (≥ 60 years). Overall survival varied significantly by age and cytogenetics. Older patients and those with t(9;22), t(4;11), low hypodiploidy/near-triploidy, or complex karyotype had a significantly inferior outcome. These population-based results demonstrate the cytogenetic heterogeneity of adult acute lymphoblastic leukemia. These data will inform the delivery of routine clinical services and the design of new age-focused clinical trials.

Abstract
Today, long-term survival is achieved in more than 80% of children 1 to 10 years old with acute lymphoblastic leukemia (ALL). However, cure rates for adults and adolescents and young adults (AYA) with ALL remain relatively low, at only 40% to 50%. Age is a continuous prognostic variable in ALL, with no single age at which prognosis deteriorates markedly. Within childhood ALL populations, older children have shown inferior outcomes, whereas younger adults have shown superior outcomes among adult ALL patients. The type of treatment (pediatric-based versus adult-based) for AYA has recently been a matter of debate. In this article the biology and treatment of ALL in AYA is reviewed.

Abstract
BACKGROUND : There are few population-based studies of long-term survival of adolescents and young adults with hematologic malignancies; most pertain to patients diagnosed in the 1990s or earlier. Period analysis was used to obtain up-to-date information on survival expectations of adolescents and young adults diagnosed with hematologic malignancies through the early 21st century. METHODS : Period analysis was used to calculate 5- and 10-year relative survival for adolescents and young adults diagnosed with Hodgkin lymphoma (HL), non-Hodgkin lymphoma (NHL), acute lymphoblastic leukemia (ALL), acute myeloblastic leukemia (AML), and chronic myelocytic leukemia (CML) for 5 5-year periods from 1981-1985 to 2001-2005, using data from the Surveillance, Epidemiology, and End Results database. RESULTS : Survival strongly improved for each of the 5 hematologic malignancies. Increases in 10-year relative survival between 1981-1985 and 2001-2005 were as follows: HL, from 80.4% to 93.4%; NHL, from 55.6% to 76.2%; ALL, from 30.5% to 52.1%; AML, from 15.2% to 45.1%; CML, from 0 to 74.5% (P < .001 in all cases). However, although survival improved steadily throughout the period examined for the lymphomas and CML, survival was stable during the late 1990s and early 21st century for the acute leukemias. CONCLUSIONS : Survival expectations for adolescents and young adults with hematologic malignancies have strongly improved since the 1980s. However, with the exception of HL, survival rates have not reached the levels observed for children diagnosed with these malignancies, and survival expectations for patients with acute leukemia have stabilized at relatively low levels.

Abstract
Background: Between 1979 and 2001, an analysis of cancer survival in young people in England, aged 13 to 24 years, showed overall improvements. However, for some diagnostic groups, little or no increases were observed. The aim of this study was to analyse the regional distribution of cancer survival in teenagers and young adults in England in order to identify patterns and potential for improvements at a regional scale. Methods: We examined geographical and temporal patterns in relative survival in cancer patients aged 13–24 years in England during the time period 1979–2001. Cancer cases were grouped according to an internationally recognised morphology-based diagnostic scheme. Results: For most diagnostic groups, there was little variation in survival between regions, except for testicular germ cell tumours (P=0.006) and colorectal carcinoma (P=0.002). For certain diagnostic groups, the temporal pattern in survival differed between regions. However, in regions that showed poor survival during the early part of the study period, greatest improvements were observed in groups such as acute lymphoid leukaemia, acute myeloid leukaemia, testicular tumours and melanoma. Conclusion: In conclusion, there was a reduction in the differences in survival between regions during the study period.

Abstract
PURPOSE Patients 16 to 21 years of age with acute lymphoblastic leukemia (ALL) have an inferior outcome compared with younger children, leading some medical oncologists to advocate allogeneic stem-cell transplantation in first remission for these patients. We examined outcome for young adults with ALL enrolled onto the Children's Cancer Group (CCG) 1961 study between 1996 and 2002. PATIENTS AND METHODS CCG 1961 entered patients with ALL 1 to 21 years of age with initial WBC count > or = 50,000/microL and/or age > or = 10 years. Randomly assigned therapies evaluated the impact of postinduction treatment intensification on outcome. We examined outcome and prognostic factors for 262 young adults with ALL. RESULTS Five-year event-free and overall survival rates for young adult patients are 71.5% (SE, 3.6%) and 77.5% (SE, 3.3%), respectively. Rapid responder patients (< 25% bone marrow blasts on day 7) randomly assigned to augmented therapy had 5-year event-free survival of 81.8% (SE, 7%), as compared with 66.8% (SE, 6.7%) for patients receiving standard therapy (P = .07). One versus two interim maintenance and delayed intensification courses had no significant impact on event-free survival. WBC count more than 50,000/microL was an adverse prognostic factor. CONCLUSION Young adult patients with ALL showing a rapid response to induction chemotherapy benefit from early intensive postinduction therapy but do not benefit from a second interim maintenance and delayed intensification phase. Given the excellent outcome with this chemotherapy, there seems to be no role for the routine use of allogeneic stem-cell transplantation in first remission for young adults with ALL.

Abstract
Although the outcomes for adults with acute lymphoblastic leukemia (ALL) lag behind the stunningly successful results seen in children, new paradigms and new discoveries bring hope that this disparity will steadily lessen. The adoption of the use of pediatric intensity-type regimens in adolescents and young adults show promise in improving outcomes in this population. Recent donor-versus-no-donor comparisons in the allogeneic transplant setting highlight a potent graft-versus-leukemia effect in ALL, and the application of reduced intensity conditioning transplants may exploit this effect while reducing nonrelapse mortality. New therapeutic targets, such as CD22 in precusor B-cell ALL and mutations in NOTCH1 in T-cell ALL, are being exploited in clinical trials. Finally, use of molecular techniques and flow cytometry to quantitate minimal residual disease will allow further stratifications of patients by risk, identification of new therapeutic targets and will lessen drug toxicity through the use of pharmacogenomics.

Abstract
Currently, 50% of adolescents with ALL are treated by adult teams and 50% by paediatric teams (following either adult or paediatric protocols). The aim of this paper is to review the results obtained with first-line chemotherapy and with haematopoietic SCT (HSCT) in adolescents with ALL. Disease biology and host factors are responsible for the differences observed between adolescents and other age categories. The outcome of adolescents with ALL after first-line chemotherapy is poorer as compared with children, although better as compared with adults. Recent studies have shown that adolescents who were enrolled in paediatric trials achieved better results than those who were enrolled in adult trials. This is most likely because of several differences, including protocol design, dose intensity and use of HSCTs, as well as better compliance to treatment and better supportive care. Disparities in the attitude towards treatment between paediatric and adult wards might also contribute to the better outcome that is observed in paediatric institutions. Indications for HSCT in children with ALL are well defined by international protocols. Only very high-risk paediatric patients are eligible for HSCT in CR1, whereas in adult trials, allogeneic or autologous HSCT are frequently offered, even to standard-risk patients in CR1. The outcome of adolescents given HSCT is poorer than in children, though better than in adults. Improving both psychosocial support during therapy and physical exercise habits represent further challenges for teams involved in the treatment of adolescents. Cooperation between paediatric and adult haematologists would surely improve the ability to recruit as many patients as possible and would promote progress in the research on adolescents. In conclusion, redefining age limits according to risk-based strategies, as well as encouraging multi-centre cooperation, should be taken into consideration to improve the outcome of this age category. Adolescents should be referred to research treatment teams that have experience in the management of paediatric ALL and they should be enrolled in international cooperative studies.

Abstract
Purpose Retrospective comparisons have suggested that adolescents or teenagers with acute lymphoblastic leukemia (ALL) benefit from pediatric rather than adult chemotherapy regimens. Thus, the aim of the present phase II study was to test a pediatric-inspired treatment, including intensified doses of nonmyelotoxic drugs, such as prednisone, vincristine, or l-asparaginase, in adult patients with ALL up to the age of 60 years. Patients and Methods Between 2003 and 2005, 225 adult patients (median age, 31 years; range, 15 to 60 years) with Philadelphia chromosome–negative ALL were enrolled onto the Group for Research on Adult Acute Lymphoblastic Leukemia 2003 protocol, which included several pediatric options. Some adult options, such as allogeneic stem-cell transplantation for patients with high-risk ALL, were nevertheless retained. Results were retrospectively compared with the historical France-Belgium Group for Lymphoblastic Acute Leukemia in Adults 94 (LALA-94) trial experience in 712 patients age 15 to 55 years. Results Complete remission rate was 93.5%. At 42 months, event-free survival (EFS) and overall survival (OS) rates were 55% (95% CI, 48% to 52%) and 60% (95% CI, 53% to 66%), respectively. Age remained an important bad prognostic factor, with 45 years of age as best cutoff. In older versus younger patients, there was a higher cumulative incidence of chemotherapy-related deaths (23% v 5%, respectively; P < .001) and deaths in first CR (22% v 5%, respectively; P < .001), whereas the incidence of relapse remained stable (30% v 32%, respectively). Complete remission rate (P = .02), EFS (P < .001), and OS (P < .001) compared favorably with the previous LALA-94 experience. Conclusion These results suggest that pediatric-inspired therapy markedly improves the outcome of adult patients with ALL, at least until the age of 45 years.

Abstract
UNLABELLED Adolescent patients with Hodgkin's lymphoma (HL) are treated either in pediatric, or in adult oncological wards. AIM The aim of our work was to compare the treatment modalities and the survival rates in adolescents with HL treated in adult (A) or pediatric (P) institutes. METHODS From January 1990 to December 2004, 138 patients (14-21 years) with HL were treated in two adult institutes (A) and 107 in the 10 centres of the Hungarian Pediatric Oncology Network (P). RESULTS Male:female ratio was 1:1.15 (A) and 1:1.38 (P). The mean age was 18.6 (A) and 15.7 (P) years. There was no difference between the distribution of the stages in the two patient groups. The distribution of histological subtypes (A and P): nodular sclerosing 47% and 59%, mixed cellularity 45% and 25%, lymphocyte rich 1.5% and 10%, lymphocyte depleted 4% and 1%, nodular lymphocyte predominant 1.5% and 3% and unknown 1% and 2%. The majority of the patients were treated with ABVD (A) and OPPA/OEPA +/- COPP (P). One hundred and fifteen (A) and 97 (P) adolescents received irradiation therapy. 80% (A) and 91% (A) of the patients got radiotherapy. In group A 14%, in group P 13% of the patients had relapse. In group A 16 patients died and in group P 7. There was no significant difference in the overall survival (OS) rates at 5 and 10 years in the two patient groups. The event-free survival (EFS) was 76.5 +/- 4% and 72.5 +/- 4% at 5 and 10 years in group A, and 85.3 +/- 4% at both times in group P ( p = 0.0452). CONCLUSION Survival rates in HL are quite high, 80-90% of the patients can be cured. Event-free survival was higher in pediatric than in adult institutes. In case of patients younger than 18 years, the survival rates were much better in pediatric institutes, so these patients should be treated in pediatric institutes or with protocols used by the pediatricians.

Abstract
AbstractImportant studies challenging previous approaches to the treatment of adults with Philadelphia chromosome–negative acute lymphoblastic leukemia (ALL) have emerged in the past decade. Donor versus no donor comparisons of allogeneic transplant highlight a potent graft-versus-leukemia effect in ALL, and the application of reduced-intensity conditioning transplants may exploit this effect while reducing non-relapse mortality. The adoption of the use of pediatric intensity-type regimens in adolescents and young adults shows promise to improve outcomes in this population. New therapeutic targets such as mutations in NOTCH1 in T-cell ALL and CD22 in pre-B ALL are being exploited in clinical trials. The application of molecular techniques and flow cytometry to quantitate minimal residual disease will allow further stratification of patients by risk. Although the outcomes of adults with ALL lag behind the stunningly successful results seen in children, new paradigms and new discoveries bring hope that this disparity will steadily lessen.

Abstract
The centres of the Hungarian Paediatric Oncology Network annually take care of 250-300 new patients with childhood cancer, every tenth of them suffering from lymphoma. The aim of our work was to analyse the data of the adolescents (14-19 years) with Hodgkin's lymphoma (HL) and non-Hodgkin's lymphoma (NHL), comparing their survival rates with younger patients under fourteen and with the international data. From January 1990 to December 2004 there were 281 children diagnosed with HL and 230 with NHL. Among the HL patients 107, while among the NHL patients 51 were older than 14 years old. In the group of HL the distribution of patients according to the stage was similar in younger and older patients. In the NHL group 55% of the children younger than 14, and 72% of the patients older than 14 years old had advanced stage disease (stage III or IV). In both groups the patients received chemotherapy according to the current paediatric protocols. The overall survival (OS) of the HL patients younger than 14 was 92.5+/-2% at 5 years and 90.3+/-2% at 10 years, and for the adolescents 93.4+/-2% and 90.7+/-3% at 5 and 10 years (n.s.). The OS of the younger children in the NHL group was 78.2+/-3% at 5 and 10 years, and 77.9+/-6% for the adolescents (n.s.). As a conclusion, survival rates of the adolescents do not differ significantly from the parameters of the patients under fourteen, so the therapy protocols used for childhood lymphomas are suitable for the treatment of the lymphomas appearing at the age of 14-19 years.

Abstract
Poor inclusion rates into clinical trials for teenagers and young adults (TYA; aged 13-24 years) have been assumed but not systematically investigated in England. We analysed accrual rates (AR) from 1 April 2005 up to 31 March 2007 to National Cancer Research Network (NCRN) Phase III trials for the commonest tumour types occurring in TYA and children: leukaemia, lymphoma, brain and central nervous system, bone sarcomas and male germ cell tumours. AR for 2005-2007 were 43.2% for patients aged 10-14 years, 25.2% for patients aged 15-19 years, and 13.1% for patients aged 20-24 years in the tumour types analysed. Compared with accrual from 1 April 2005 to 31 March 2006, AR between 1 April 2006 and 31 March 2007 increased for those aged 10-14 and 15-19 years, but fell for those aged 20-24 years. AR varied considerably among cancer types. Despite four trials being available, patients over 16 years with central nervous system tumours were not recruited. Rates of participation in clinical trials in England from 2005 to 2007 were much lower for TYA older than 15 years compared with children and younger teenagers. The variations in open trials, trial age eligibility criteria and extent of trial activation in treatment centres in part explain this observation. Other possible influences, such as difficulties associated with the consent of TYA require further evaluation. Closer dialogue between those involved in planning and running trials for children and for adults is necessary to improve trial availability and recruitment. Further research is required to identify trends in trial availability and accrual for those tumours constituting the remaining 26% of TYA cancers.

Abstract
PURPOSE OF REVIEW Despite improvements in the achievement of complete remission and progress in the supportive care of adults with acute lymphoblastic leukemia during the last decade, the majority of patients have eventually relapsed with overall survival in adult acute lymphoblastic leukemia of only 30-40%. However, the recent approach of adapting therapy according to biologic features appears to be resulting in significant progress for specific subsets of adults with acute lymphoblastic leukemia. RECENT FINDINGS The present review highlights some of these new risk-adapted approaches focusing on recent advances in treatment of Philadelphia chromosome positive acute lymphoblastic leukemia and mature B-cell acute lymphoblastic leukemia using biologically targeted therapies, and new approaches to treatment of acute lymphoblastic leukemia in older adolescents and young adults, adopting therapeutic strategies employed in the successful treatment of children with acute lymphoblastic leukemia. A recent study that examines the role of allogeneic stem cell transplant for adults with acute lymphoblastic leukemia in first remission will also be reviewed. SUMMARY The subset-specific approach to therapy of adult acute lymphoblastic leukemia is beginning to result in promising improvements in survival. Future improvements in survival of adults with acute lymphoblastic leukemia will depend on participation in large cooperative group trials using biologically defined protocols for this relatively rare and heterogeneous group of diseases.

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
PURPOSE Retrospective studies have shown that adolescents and young adults with acute lymphoblastic leukemia (ALL) treated with pediatric protocols have better outcomes than similarly aged patients treated with adult protocols, but prospective studies comparing adolescents and young adults using pediatric schedules are scarce. The ALL-96 protocol was addressed to compare the toxicity and results of a pediatric-based protocol in adolescents (age 15-18 years) and young adults (age 19-30 years) with standard-risk (SR) ALL. PATIENTS AND METHODS Adolescents (n = 35) and young adults (n = 46) received a standard five-drug/5-week induction course followed by two cycles of early consolidation, maintenance with monthly reinforcement cycles up to 1 year in continuous complete remission (CR) and 1 year with standard maintenance chemotherapy up to 2 years in CR. RESULTS Adolescents and young adults were comparable in the main pretreatment ALL characteristics. The CR rate was 98% and. after a median follow-up of 4.2 years, 6-year event-free survival (EFS) and overall survival (OS) were 61% (95% CI, 51% to 72%) and 69% (95% CI, 59% to 79%), respectively, with no differences between adolescents and young adults. The hematologic toxicity in consolidation and reinforcement cycles was higher in young adults than in adolescents. Slow response to induction therapy was the only parameter associated with poor EFS (34% v 67%) and OS (40% v 76%). CONCLUSION The response to the pediatric ALL-96 protocol was identical in adolescents and young adults despite a slight increase in hematologic toxicity observed in adults. This justifies the age-unrestricted use of pediatric regimens to treat patients with SR ALL.

Abstract
Rapid diagnosis, timely initiation of optimal treatment and good supportive care should be the gold standard for all patients who develop cancer, irrespective of age and where they live. This article reviews the evidence that teenagers/adolescents and young adults may be disadvantaged with regard to access to care. Delays in diagnosis and the reasons for them (patient and professional), low enrolment into clinical trials, suboptimal treatment strategies and place of care are addressed. We must access the voice of the young, address their needs, and involve them more in decisions concerning their own health. Progress is being made slowly in several countries and international collaboration linking patients, health care professionals, governmental and non-governmental agencies is essential. Such international collaboration and focus, with specific research goals are suggested in order to make variation in access to optimal care become a thing of the past.

In the United States, Europe, and Australia, and probably all countries of the world, older adolescents and young adults with cancer are under-represented in clinical trials of therapies that could improve their outcome. Simultaneously, the survival and mortality rates in these patients have mirrored the clinical trial accrual pattern, with little improvement compared with younger and older patients. This suggests that the relative lack of participation of adolescent and young adult patients in clinical trials has lessened their chances for as good an outcome as that enjoyed by patients in other age groups. Thus, increased availability of and participation in clinical trials is of paramount important if the current deficits in outcome in young adults and older adolescents are to be eliminated. Regardless of whether there is a causal relationship, the impact of low clinical trial activity on furthering our scientific knowledge and management of cancer during adolescence and early adulthood is detrimental.

Abstract
One explanation for the relative lack of progress in treating cancer in adolescents and young adults is that the biology of malignant diseases in this age group is different than in younger and older persons, not only in the spectrum of cancers but also within individual cancer types and within the patient (host). Molecular, epidemiological and therapeutic outcome comparisons offer clues to this distinctiveness in most of the common cancers of adolescents and young adults. Translational and clinical research should not assume that the biology of cancers and patients is the same as in other age groups, and treatment strategies should be tailored to the differences.

Abstract
Acute lymphoblastic leukaemia, a malignant disorder of lymphoid progenitor cells, affects both children and adults, with peak prevalence between the ages of 2 and 5 years. Steady progress in development of effective treatments has led to a cure rate of more than 80% in children, creating opportunities for innovative approaches that would preserve past gains in leukaemia-free survival while reducing the toxic side-effects of current intensive regimens. Advances in our understanding of the pathobiology of acute lymphoblastic leukaemia, fuelled by emerging molecular technologies, suggest that drugs specifically targeting the genetic defects of leukaemic cells could revolutionise management of this disease. Meanwhile, studies are underway to ascertain the precise events that take place in the genesis of acute lymphoblastic leukaemia, to enhance the clinical application of known risk factors and antileukaemic agents, and to identify treatment regimens that might boost the generally low cure rates in adults and subgroups of children with high-risk leukaemia.

Abstract
Acute lymphoblastic leukemia (ALL), the most common type of cancer in children, is a heterogeneous disease in which many genetic lesions result in the development of multiple biologic subtypes. Today, with intensive multiagent chemotherapy, most children who have ALL are cured. The many national or institutional ALL therapy protocols in use tend to stratify patients in a multitude of different ways to tailor treatment to the rate of relapse. This article discusses the factors used in risk stratification and the treatment of pediatric ALL.

Abstract
AbstractSurvival of children with acute lymphoblastic leukemia (ALL) is often described as the success story for oncology. The improvements in the treatment of ALL represent the work of cooperative groups at their best. Fifty years ago a pediatric oncologist would have never considered using the term “cure” in a discussion with a family whose child was diagnosed with ALL. Today the term is not only used in the initial discussion but referred to frequently thereafter. However, as we all know, cure is not assured and is not obtained without sequelae. This review will focus on the improvements in treatment for newly diagnosed ALL in children and adolescents according to risk group and some of the challenges that remain despite the improved outcome.

Abstract
Avascular necrosis (AVN) is a serious complication of acute lymphoblastic leukaemia (ALL) therapy. Little is known of the scope and magnitude of this problem among adults with ALL. We analysed the incidence and risk factors for AVN in 1053 patients on the UKALLXII/ECOG2993 study. AVN affected 99 joints in 42 patients at a median of 2.2 years post-diagnosis, giving a crude incidence rate of 4.0%. Statistically significant risk factors for the development of AVN were age and treatment with chemotherapy. Patients receiving prolonged chemotherapy without stem cell transplant were at significantly greater risk of developing AVN than stem cell transplant recipients (P<0.00005). The actuarial incidence of AVN was 29% at 10 years in patients <20 years old compared to 8% at 10 years in those >20 years old; P=0.0004; odds ratio 0.28 (95% CI=0.14-0.56).

Abstract
Adolescent patients with cancer reside in a "no-man's land" between the world of pediatric oncology and that of "adult" medical oncology. As compared to younger and older patients, adolescents and young adults are under-represented on clinical trials. This relative lack of participation in clinical protocols has been associated to a lack of progress in survival improvement over the last years. One of the main reasons for the deficit in protocol enrolment and the worse outcome of adolescents (when compared in particular to children) is the lack of awareness by the public, community and healthcare systems that cancer may occur in this age group. However, physicians--inadequately trained or reluctant to care for adolescents--have important responsibilities. Most 15- to 19-year-olds diagnosed with cancer are treated at adult facilities, although two-thirds to three-fourths of their cancers are typical of those that occur in the pediatric age range. The best choice may be to treat them according to their type of tumor, not according to their age: "pediatric" tumors treated by pediatric oncologists, "adult" tumors by adult medical oncologists, regardless of the patient's age. This solution, however, is probably appropriate for the tumor, but not necessarily for the patient. Adolescents are neither old children nor young adults, and are very complicated individuals, with unique socio-psychological problems and needs, that may be addressed only by dedicated professionals, adequately trained and supported. The ultimate challenge is the development of a new discipline, adolescent/teenage and young adult oncology, devoted to the care of these patients.

Abstract
Purpose Historically, adolescents with acute lymphoblastic leukemia (ALL) have had inferior outcomes when compared with younger children. We report the outcome of adolescents treated on Dana-Farber Cancer Institute (DFCI; Boston, MA) ALL Consortium Protocols conducted between 1991 and 2000. Patients and Methods A total of 844 patients aged 1 to 18 years, with newly diagnosed ALL were enrolled onto two consecutive DFCI-ALL Consortium Protocols. We compared outcomes in three age groups: children aged 1 to 10 years (n = 685), young adolescents aged 10 to 15 years (n = 108), and older adolescents aged 15 to 18 years (n = 51). Results With a median follow-up of 6.5 years, the 5-year event-free survival (EFS) for those aged 1 to 10 years was 85% (SE, 1%), compared with 77% (SE, 4%) for those aged 10 to 15 years, and 78% (SE, 6%) for those aged 15 to 18 years (P = .09). Adolescents were more likely to present with T-cell phenotype (P < .001) and less likely to have the TEL-AML1 fusion (P = .05). The incidence of pancreatitis and thromboembolic complications, but not asparaginase allergy, was higher in patients ≥ 10 years of age compared with those younger than 10 years. However, there was no difference in the rate of treatment-related complications between the 10- to 15-year and 15- to 18-year age groups. Conclusion Adolescents were more likely to present at diagnosis with biologically higher risk disease (T-cell phenotype and absence of the TEL-AML1 fusion) and more likely to experience treatment-related complications than younger children. However, the 5-year EFS for older adolescents was 78% ± 6%, which is superior to published outcomes for similarly aged patients treated with other pediatric and adult ALL regimens. Based on this experience, we currently are piloting our regimen in patients aged 18 to 50 years.

Abstract
AbstractThe decision to proceed to transplant for adult patients with acute lymphoblastic leukemia (ALL) is not clear-cut. Relapse and nonrelapse mortality continue to plague the outcome of hematopoietic stem cell transplantation (HSCT) even when undertaken in complete remission (CR). Those considered to be at high risk for relapse often are considered for HSCT in first complete remission (CR1) while those at lower risk may not be referred until they have relapsed, when their chances for cure are very poor. In some patients who have a suitable histocompatible sibling, disease- or patient-related factors may override the potential benefit of allogeneic HSCT. Because many patients do not have a suitable histocompatible sibling, one has to consider the relative merits of autologous transplantation versus use of an alternative allogeneic stem cell source, such as a matched-unrelated donor (MUD), umbilical cord blood (UCB) donor, or haploidentical donor. Deciding among these options in comparison to chemotherapy even in high-risk patients is difficult. In the review, the risks and benefits of these choices are discussed to determine whether and by what means to proceed to HSCT in adult patients with ALL who are in CR1. Presented are two patients with ALL and a discussion of how the data we provide would lead to a decision about the selection of therapy.
