Abstract
Approximately 1 in 640 adults between 20 and 40 years of age is a survivor of childhood cancer. However, survival has often come at the expense of increased risk of long-term complications, including chronic health conditions and higher mortality rates. Similarly, long-term survivors of childhood non-Hodgkin lymphoma (NHL) experience significant morbidity and mortality related to prior cancer treatments, highlighting the importance of primary and secondary prevention strategies to mitigate late toxicity. As a result, effective treatment regimens for pediatric NHL have evolved to reduce both short- and long-term toxicity through cumulative dose reductions and elimination of radiation. The establishment of effective regimens facilitates shared decision-making opportunities for frontline treatment selection that considers efficacy, acute toxicity, convenience, and late effects of treatments. The current review seeks to merge current frontline treatment regimens with survivorship guidelines to enhance understanding of potential long-term health risks to facilitate best treatment practices.

Abstract
PURPOSE The widely used, risk-based Lymphome Malin de Burkitt (LMB) chemotherapy regimen has improved survival rates for children with mature B-cell non-Hodgkin lymphoma (NHL); however, associated late effects remain understudied. We assessed late health outcomes after LMB treatment in the Childhood Cancer Survivor Study. PATIENTS AND METHODS Multivariable regression models compared chronic health conditions, health status, and socioeconomic and neurocognitive outcomes between survivors of NHL treated with the LMB regimen (n = 126), survivors of NHL treated with non-LMB regimens (n = 444), and siblings (n = 1,029). RESULTS LMB survivors were a median age of 10.2 years (range, 2.5 to 20.5 years) at diagnosis and 24.0 years (range, 10.3 to 35.3 years) at evaluation. Compared with siblings, LMB survivors were at increased risk for adverse health outcomes. However, survivors of NHL treated with LMB and non-LMB regimens did not differ with regard to risk of having any chronic health conditions, impaired health status, neurocognitive deficits, or poorer socioeconomic outcomes. Increased risk for the following specific neurologic conditions was observed in LMB survivors compared with non-LMB survivors: epilepsy (relative risk [RR], 15.2; 95% CI, 3.1 to 73.4); balance problems (RR, 8.9; 95% CI, 2.3 to 34.8); tremors (RR, 7.5; 95% CI, 1.9 to 29.9); weakness in legs (RR, 8.1; 95% CI, 2.5 to 26.4); severe headaches (RR, 3.2; 95% CI, 1.6 to 6.3); and prolonged arm, leg, or back pain (RR, 4.0; 95% CI, 2.2 to 7.1). The survivors from the group C LMB risk group (n = 50) were at the highest risk for these conditions; however, except for worse functional status (odds ratio, 2.7; 95% CI, 1.2 to 5.8), they were not at increased risk for other adverse health status or socioeconomic outcomes compared with non-LMB survivors. CONCLUSION Survivors treated with LMB and non-LMB regimens are largely comparable in late health outcomes except for excess neurotoxicity among LMB survivors. These data inform treatment efforts seeking to optimize disease control while minimizing toxicity.

Abstract
Modern chemotherapy for childhood Burkitt lymphoma has its origins in Africa, where treatment evolved from one or two doses of single agents, which were curative in some patients, to combinations of non-cross-resistant drugs. Subsequently, in Europe and the United States, high-dose methotrexate, high-dose cytarabine, etoposide, and ifosfamide were found to be active in children with recurrent disease and were incorporated into primary therapy for patients with high-risk disease. These third-generation protocols produce overall cure rates around 90%. Therapy regimens for adults with Burkitt lymphoma have been developed by modifying second-generation pediatric protocols, and few investigators have used the third-generation pediatric regimens that include higher doses of methotrexate and additional agents. The weight of evidence strongly suggests that high-dose therapy with stem cell rescue in first remission cannot substitute for intensive therapy from the outset. Tolerance of intensive regimens by the elderly is a legitimate concern, but it seems appropriate to modify therapy only when necessary in individual patients. The value of rituximab and granulocyte colony-stimulating factor in patients undergoing intensive therapy (particularly the elderly) is worthy of further exploration. Because childhood diffuse large-B-cell leukemia (DLBCL) responds equally well to therapy for Burkitt lymphoma, more intensive therapy and intensive support might also give better results in at least a subset of adults with advanced DLBCL-perhaps defined on the basis of limited molecular profiling, which has provided new information about the categories of aggressive B-cell lymphomas.

Abstract
PURPOSE We analyzed the prevalence, clinical pattern, and prognostic impact of CNS involvement in a large cohort of children and adolescents diagnosed with non-Hodgkin's lymphoma (NHL), with special attention to differences according to NHL subtype. PATIENTS AND METHODS From October 1986 to December 2002, 2,381 patients (median age, 9.37 years; range, 0.2 to 23.8 years; female-to-male ratio, 1:2.7) from Germany, Austria, and Switzerland were registered. A total of 2,086 patients were eligible for the consecutive multicenter protocols NHL-Berlin-Frankfurt-Münster [BFM] -86, NHL-BFM-90, and NHL-BFM-95, and could be evaluated for outcome. RESULTS CNS involvement was diagnosed in 141 (5.9%) of 2,381 patients and was associated with an advanced stage of NHL. The percentage of CNS-positive patients was 8.8% for Burkitt's lymphoma/Burkitt's leukemia (BL/B-ALL), 5.4% for precursor B-lymphoblastic lymphoma (pB-LBL), 3.3% for anaplastic large-cell lymphoma, 3.2% for T-cell-LBL, 2.6% for diffuse large B-cell lymphoma, and 0% for primary mediastinal large B-cell NHL (P < .001). Most CNS-positive patients with pB-LBL, T-LBL, or BL/B-ALL had meningeal disease. The probability of event-free survival (pEFS; +/- SE) at 5 years was 85% +/- 1% for the 2,086 protocol patients (median follow-up, 6.5 years; range, 0.3 to 17.7 years). For the 112 CNS-positive patients, pEFS was 64% +/- 5%, compared with 86% +/- 1% for the 1,927 CNS-negative patients (P < .001). Although CNS disease had no impact on pEFS for advanced-stage T-LBL patients, CNS-positive patients with BL/B-ALL had a worse average outcome than CNS-negative patients with stage IV BL/B-ALL (60% +/- 5% v 81% +/- 3%; P < .001). In multivariate analysis, CNS disease was the strongest predictor for relapse in BL/B-ALL patients with advanced-stage disease. CONCLUSION Six percent of childhood/adolescent NHL patients were CNS positive. However, the prevalence, pattern, and prognostic impact of CNS involvement differed among NHL subtypes.

Abstract
PURPOSE To determine the toxicity and response rate in children treated with dexamethasone, etoposide, cisplatin, high-dose cytarabine, and L-asparaginase (DECAL) for recurrent non-Hodgkin's lymphoma (NHL) and Hodgkin's disease (HD). PATIENTS AND METHODS Ninety-seven children with recurrent NHL (n = 68) or HD (n = 29) were enrolled. Treatment consisted of two cycles of DECAL, then bone marrow transplantation or up to four cycles of ifosfamide, mesna, and etoposide alternating with DECAL maintenance therapy. RESULTS After two cycles of DECAL induction therapy, complete response (CR) or partial response (PR) was reported in 19 (65.5%; 10 CRs and nine PRs) of 29 patients with HD and 29 (41.6%; 23 CRs and six PRs) of 68 patients with NHL. When only 24 patients with HD and 58 patients with NHL who were assessable for response were considered, the response rates were 79.2% (19 of 24 patients) and 50.0% (29 of 58 patients), respectively. Five-year event-free survival was 26% +/- 9% and 23% +/- 5% in patients with HD and NHL, respectively. Five-year survival was 31% +/- 14% and 30% +/- 6%, respectively. Although median time to treatment failure was significantly longer in patients with HD (EFS, P =.002; survival, P =.011), this difference did not translate into a higher long-term survival. Grade 3 or 4 toxic effects were observed during induction in 70 (72%) of 97 patients and during maintenance in 45 (70%) of 64 courses of DECAL therapy. Pancytopenia and systemic infections in particular were frequently observed. Other toxic effects were uncommon. Although not a formal part of the therapy or the study design, 42 patients who responded to therapy who underwent bone marrow transplant did not show any benefit from this approach. CONCLUSION DECAL is an effective and tolerable salvage regimen for treating patients with recurrent NHL and HD.

Abstract
Although high-dose methotrexate has been extensively studied in children with newly diagnosed acute lymphoblastic leukemia (ALL), there are fewer data in children with relapsed ALL, many of whom have been heavily pretreated and have subclinical kidney dysfunction. We characterized the pharmacokinetics of adaptively controlled methotrexate given as a 24-h infusion during consolidation therapy in 24 children with relapsed ALL. To achieve the target steady-state concentration of 65 microM, dosage adjustments were required in 14 patients, with doses ranging from 2854 to 6700 mg/m2 per course. The mean steady-state plasma concentration (Cpss) of 68.0 microM was different (P = 0.025) than the predicted Cpss (mean = 87.4 microM; range 35.7-184 microM) had no adjustment in dose been made. The coefficient of variation in Cpss was reduced from 41% to 18% by individualizing doses. Predisposing factors that correlated with decreased methotrexate clearance were female sex (P = 0.03), age greater than 6 years (P = 0.01), and prior history of heavy amphotericin B treatment (>30 mg/kg) (P = 0.03), but no factor predicted low clearance as well as the measured initial methotrexate clearance during the infusion (P < 0.0001). There was no life-threatening toxicity with the regimen. We conclude that dosage individualization decreases interpatient variability and avoids potentially toxic methotrexate exposures in heavily pretreated ALL patients.

Abstract
Abstract
To evaluate the role of high-dose chemotherapy (HDC) followed by autologous bone marrow transplantation (ABMT) in children with poor-prognosis Burkitt's lymphoma, the European Lymphoma BMT registry was critically reviewed. Between February 1979 and July 1991, a selected group of 89 children (78 boys and 11 girls) were considered as ABMT candidates in 12 European cancer centers for the following reasons: poor initial response (PIR) to first-line chemotherapy in 28 patients, primary refractory disease (PRD) in nine patients, sensitive relapse (SR) in 38 patients, and resistant relapse (RR) in 14 patients. The median age at ABMT was 8.2 years (range, 2.8 to 16.2 years). Thus, this report reflects data for patients surviving the salvage attempt deemed appropriate for HDC/ABMT and who then actually underwent the transplant procedure. The median follow-up period after HDC/ABMT was 4.3 years (range, 2 to 12 years). The prognosis was dismal for PRD patients and those with RR, ie, all patients died within 1 year. The 5-year event-free survival (EFS) was 56.6% (P < .0001) for patients in partial remission (PR) and 48.7% (P = .002) for patients with SR. The toxic death rate was 11.1%. Continuous complete remissions (CRs) in 39.4% of these otherwise incurable children highlight the fact that HDC/ABMT was an effective complementary procedure after conventional-dose chemotherapy protocols used during the given period. In addition, these data show that patients with PRD or RR clearly had no advantage from this aggressive and cost-intensive procedure. It has to be considered that the need for HDC/ABMT has greatly diminished in parallel with the improvement in survival using the modern intensive pulsed CCT of current protocols. To further rescue patients failing to respond to modern protocols, new approaches appear necessary, ie, combinations of HDC with antibody-targeted therapy plus allogeneic BMT for the additional benefits of the potential graft-versus-lymphoma effect.

Abstract
The high cure rate obtained in most paediatric lymphomas allows an optimistic vision of future treatments, with decreased primary late effects observed in patients who have completed therapy: decreased cognitive functional impairment, reproductive dysfunction, poor social adaptation, and risk of second malignancies. The deleterious effects of radiation therapy on neurocognitive functions is now well documented (Meadows et al, 1981) but, apart from rare acute toxicities (Sasazaki et al, 1992), reports on those following high-dose methotrexate are scarce, and sometimes discordant (Jannoun and Chessels, 1987; Robertson et al, 1992). Longer follow-up evaluation is warranted before definitive conclusions concerning the relationship between computed tomography scan findings and clinical outcome can be reached. The reproductive function of males is much more severely altered than that of females (Jaffe et al, 1988). Several reports have demonstrated the major dose-dependent toxicity of alkylating agents on male fertility. Male patients receiving more than 9 g/m2 of cyclophosphamide have a particularly high risk of sterility (Aubier et al, 1989) and children with less than 4 g/m2 of cyclophosphamide, a very low risk Patte et al, 1996a). Women treated before the age of 20 who do not receive abdominal irradiation usually have normal reproductive function, although early puberty (Quigley et al, 1989) and early menopause (Byrne et al, 1992) have been documented. The risk of a second malignancy is not as great as in children with a solid tumour or Hodgkin's disease (Anderson et al, 1993). The risk is higher in patients treated with alkylating agents (Lemerle et al, 1989). With the increasing cure rate, a social problem may arise for adults who "have had cancer'. The increased awareness by politicians and health insurance companies should help to solve, at least partially, this new problem (Monaco, 1987). As cure rates increase, emerging concerns involve the familial repercussions of this heavy treatment (Lansky et al, 1978; Cairns et al, 1979). At this stage, there is no demonstrated deleterious effect from treatment for the progeny of cured children (Mulvihill et al, 1987; Stein, 1993). Cure of children with lymphoma is a reality, and one should think in terms of "complete cure' when facing a distressed child with a heavy tumour burden arriving for diagnosis (Schweisguth, 1979). Since 1980, the progress of molecular biology techniques has permitted the precise molecular characterization of gene alterations (oncogenes, immunoglobulins, and T-cell receptor genes) involved in the process of malignant transformation of normal lymphocytes (Bhatia et al, 1996; Williams et al, 1996). In parallel, treatment of malignant NHL of childhood has improved dramatically. The progress in molecular biology has not led to a modification of the clinical management of NHL of childhood which remains mainly empirical. Precise cytohistological classification of lymphomas has resulted in the characterization of low- and high-risk patients requiring distinct therapeutic approaches. The major goals of the next few years will be to increase the cure rates of those patients with CNS and bone marrow involvement at diagnosis, probably through an intensification of chemotherapy (increase in the dose or intensity of the chemotherapy); to define precisely subgroups of good-prognosis patients requiring less aggressive treatment that would decrease the risk of long-term events; and to salvage previously heavily treated patients at relapse. The precise analysis of gene alterations in lymphoma cells of a given patient may have important clinical applications in this respect (Bhatia et al, 1996).

Abstract
Burkitt's lymphoma and L3-ALL are different forms of the same disease: B-cell disease. Therapeutic improvement has been considerable over the past 10 years. In France, four consecutive multicentre LMB studies of the SFOP greatly contributed to this improvement. An overall cure rate of 90% can now be achieved in children with a short intensive risk adapted polychemotherapy regimen based on high-dose fractionated CPM, HD MTX (3 g/m2), Ara-C in continuous infusion. For patients with ALL or with CNS involvement, the addition of CNS-directed therapy with a higher dose of MTX (8 g/m2), HD Ara-C (3 g/m2 x 4), VP 16, triple intrathecal injections and cranial irradiation greatly improved survival: 87% for ALL and 73% for patients with CNS involvement. In adults, the application of the paediatric protocol is possible with acceptable toxicity and a retrospective study of 41 cases treated according to a LMB protocol showed a cure rate of 71%. Such a regimen should now be proposed to adults and studied prospectively.

Abstract
Case report of the appearance of a highly malignant cerebral non-Hodgkin's lymphoma of a diffuse large cell type, type B, occurring at the immediate onset of chemotherapy for a stage IV (mediastino-pulmonary) Hodgkin's disease (nodular sclerosis) diagnosed in a 16-year-old boy. The treatment of this cerebral lymphoma associated primary chemotherapy with high dose methotrexate, high dose aracytine, etoposide, and ifosfamide. The chemotherapy proved to be highly efficient, producing complete remission. Thoracic and abdominal irradiation for Hodgkin's disease was performed concomitantly with chemotherapy for the non-Hodgkin's lymphoma. This treatment was followed by 36 Gy of cerebral irradiation. Thirty-six months after the discovery of the cerebral non-Hodgkin's lymphoma the patient was still disease-free and doing well.

Abstract
From May 1981 to June 1989, 84 children with non-B-cell lymphoma (82 lymphoblastic, 1 T-cell immunoblastic, 1 unclassified diffuse lymphoma) were treated in the pediatric department of the Institut Gustave Roussy according to a protocol called LMT81, which was derived from the LSA2L2 protocol of Wollner and modified by the adjunction of 10 courses of high dose methotrexate to improve the CNS prophylaxis. No planned irradiation was performed except in cases of initial tests (2 patients) or CNS (5 patients) involvement and residual mass (2 patients). Sixty patients had mediastinal involvement; for the others, primaries were in the head and neck (7), nodes (2), (sub)cutaneous (4), bone (7), and elsewhere (2). According to Murphy's staging system, there were 2 stage I, 6 stage II, 33 stage III, and 43 stage IV. Among the stage IV patients, 41 had bone marrow involvement, 24 of them with more than 25% blast cells in bone marrow and 19 with blast cells in blood; 7 had CNS involvement. Three patients did not achieve complete remission, 4 died in remission (two measles, one post-transfusion AIDS, one unexplained definitive aplasia) and 13 relapsed at 2 to 29 months (median-13 months). Among the 77 patients without initial CNS involvement, there was only one isolated CNS relapse. With a median follow-up of 57 months (10-106 months), the event-free survival is 75% (SE 2.5) for the 84 patients with a plateau at 29 months, 73% (SE 8) for stage I and II patients, 79% (SE 4) for stage III, and 72% (SE 4) for stage IV patients. Survival was similar in each stage group. Reasons for failure of treatment, however, were different, being toxic deaths in stage II; initial therapy resistance, early relapses, and toxic deaths in stage III; and tumor failures in stage IV. In conclusion, this protocol is efficacious on T and non-T, non-B childhood lymphoma with a low incidence of CNS relapse. A future study will seek to diminish toxicity and long-term sequellae while at least maintaining the same cure rate of patients.

Abstract
In the French nonHodgkin's lymphoma protocols, central nervous system prophylaxis is provided by high-dose methotrexate (HD-MTX), given as a 3-hour IV infusion of 3 g/m2 MTX along with intrathecal MTX injection. The incidence of CNS relapse is less than 3%. We designed a study to evaluate the MTX transfer across the blood brain barrier in terms of cytotoxic concentrations, during these short-term infusions. Cerebrospinal fluid and plasma MTX levels were measured during 61 courses in 29 children with nonHodgkin's lymphoma; none of them had central nervous system disease. Samples were obtained either 4, 12, 18, or 24 hours after the start of HD-MTX IV infusion. A potentially cytotoxic MTX level (10(-6)M) was reached in all courses at 4 hours (median: 2.3 X 10(-6)M) and remained available in 8/16 courses at 12 hours (median: 1.0 X 10(-6)M) and in only 2/17 courses at 18 hours (median: 0.29 X 10(-6)M). Twenty-four hours after the start of HD-MTX IV infusion, CSF MTX level was always less than 10(-6)M. The plasma MTX levels were 260, 1.3, 1.0, and 1.7 X 10(-6)M at 4, 12, 18, and 24 hours, respectively. There was no correlation between plasma and CSF MTX levels. These data show that potentially cytotoxic MTX concentrations can be reached in CSF after a 3-hour IV infusion of 3 g/m2 in every patient and remain available for at least 8 hours in half of them.
