Abstract Abstract 323 Event-free survival (EFS) at 5 years in pediatric ALL is > 80% with dose intensive multi-agent chemotherapy. In contrast, adult ALL still has an unsatisfactory outcome, which may partly be due to less cumulative dosing of chemotherapeutic agents and less strict adherence to timing of successive cycles of chemotherapy. Given the earlier reported feasibility of pediatric schedules in adolescent patients, the HOVON group performed a prospective multicenter phase II trial to evaluate the feasibility and efficacy of an intensified treatment regimen in adult patients with newly diagnosed ALL aged 18–40 years. The treatment regimen was based on the French FRALLE-2000 protocol, including dose intensification for steroids, vincristine, L-asparaginase, and high dose methotrexate (MTX). Fifty-four patients, median age 26 years (range 17–39) were enrolled in 15 centres in the Netherlands and Belgium between December 2005 and August 2007. After a prednisolon prephase and a multidrug remission-induction (prednisolon, daunorubicin, vincristine, cyclophosphamide and L-asparaginase), patients received consolidation containing 5000 mg/m2 MTX twice, two intensifications with intensified L-asparaginase, interspersed by an interphase with again two times high dose MTX, and maintenance chemotherapy (oral MTX and 6-mercaptopurine (6-MP) with reinduction with vincristine and prednisolon) for two years. CNS prophylaxis with MTX was delivered intrathecally 18 times. Standard risk patients with an HLA-identical sibling stem cell donor proceeded to allogeneic stem cell transplantation (alloSCT) after the first intensification, high risk patients received alloSCT from either sibling or unrelated donors. Adherence to the treatment schedule was urged by defining a strict timetable. Feasibility was defined by completion of chemotherapeutic and alloSCT protocol treatment within this a pre-defined timeframe. Thirty-five patients (65%) had B-cell phenotype ALL, 17 (31%) had T-cell phenotype and 2 (4%) had biphenotypic leukemia. Moreover, 23 patients (43%) had high risk disease, of whom 9 patients with BCR-ABL positive ALL. In total 33 patients fully completed treatment as scheduled, including 18 alloSCT recipients. Complete remission (CR) was achieved in 91% (95% CI: 80–97). After a median follow-up of 26 months (range 15–36 months), 2-year event-free-survival (EFS) is 68% (95% CI: 53–78), 2-year disease free survival (DFS) 74% (95% CI: 59–84) and the 2-year overall survival (OS) 70% (95% CI: 55–81). Fifteen patients (28%) died, including 8 due to relapsed/refractory ALL, 3 due to infection, 3 due to toxicity and 1 due to graft versus host disease. CTC grade 4-5 toxicities (mainly liver/kidney function abnormalities and peripheral neuropathy) were observed in 15% during induction and 13% during consolidation. Severe infections (CTC grade 3-4) primarily occurred during induction (41%) and consolidation (39%). Failures were due to not reaching CR in 5 patients, early relapse in 2, severe extramedullary drug toxicity in 3, excessive delay in 7 and other reasons not otherwise specified (but most likely due to toxicity) in 4 patients. In conclusion, these data show that a dose-intensified chemotherapeutic regimen based on a pediatric schedule is safe and feasible in most adult ALL patients up to the age of 40, although a delay of subsequent cycles was frequently observed. Early efficacy data suggest a high CR rate and favourable DFS and OS. Based on this experience, a randomised phase III trial has recently been initiated.

Abstract R-HDS 0305 (Clinical Trials. gov. number NCT00355199) is a multi-centre, unblinded, randomized controlled phase III trial involving 240 patients in 3 years from 16 Italian Cancer Centres, with DLBCL without CNS involvement, advanced stage (stage ≥IIB, bulk), age from 18 to 60 years with ECOG-PS=0–3 and aaIPI=2–3 or age from 61 to 65 years with ECOG-PS=0–2 and IPI 3–5. The control group received R-CHOP-14, which comprised 8 courses of chemotherapy every 14 days, supported by GCSF (day 7–11)±IFRT, if they achieved at least a PR after 4 cycles. Cases refractory to R-CHOP-14 were given R-HDS as salvage therapy. Experimental arm consisted in a R-HDS program, including a debulking phase of 3 courses of doxorubicin-containing chemotherapy (APO), followed by high-dose (HD)-cyclophosphamide (CTX) 7g/sqm, HD-Ara-C (2 g/sqm every 12 hours for 6 days), HD-etoposide 2g/sqm+Cisplatin 100 mg/sqm. After HDS chemotherapy, HD-mitoxantrone plus melphalan (60 and 180 mg/sqm) or a BEAM (BCNU 300 mg/sqm, etoposide 200 mg/sqm, Ara-C 4000 mg/sqm, L-PAM 140 mg/sqm) conditioning regimen with ASCT±IFRT was planned. Rituximab (375 mg/sqm) is given for a total of 6 doses, twice after HD-CTX and HD-Ara-C, as in vivo purging before CD34+ cells harvest, and twice after ASCT. The primary outcomes of the study are complete remission and disease-free survival, overall survival, event-free survival and toxicity. From July 2005 to July 2007, 89 patients were enrolled in the study (R-CHOP-14=43; R-HDS=46). The median age was 51 (range 19–65 years), 11 (12%) had ≥60 years and the M/F was 1.3. Patients presented with adverse features such as advanced stage (88%), BM infiltration (28%), bulky disease (71%), elevated LDH (84%), poor ECOG-PS (55%) and >1 extranodal sites (59%). Until now only 3 patients (3.4%) were refractory to planned treatment: 1/43 (2%) patients belonging to R-CHOP-14 arm shifted to R-HDS salvage treatment and other 2 patients died from lymphoma progression. The main G 3–4 WHO toxicity was haematological: anemia, granulocytopenia and thrombocytopenia occurred in 8%, 18% and 13% of patients, respectively. Grade 2–3 gastrointestinal toxicity and infectious episodes were recorded in 6% and 9% of patients, respectively. Two patients recovered from acute respiratory distress and 2 died of treatment-related toxicity (2.2%). In conclusion, if the R-HDS trial confirms earlier results, preliminary data show that intensive programs such as dose-dense chemo-immunotherapy and R-HDS with ASCT are feasible until 65 years with an acceptable toxic profile, also on the multi-centre basis. At completion of the trial we will assess the role of R-HDS and ASCT on the outcome of high-risk patients with DLBCL.

Abstract Introduction Patients with asymptomatic early Rai or Binet stage chronic lymphocytic leukemia (CLL) do not benefit from mono-chemotherapy. Therefore, clinical observation without treatment (watch&wait; W&W) has been the gold standard for the management of these patients. Chemoimmunotherapy with FCR improves the outcome of patients with advanced CLL, but its efficacy in early stage disease has not been investigated. Several clinical and biological variables identify those patients who have a high risk of an aggressive disease course and who might benefit from early interventions. Consequently, this trial was conducted to test the value of FCR treatment in patients with early stage, high-risk CLL. Methods This report represents the endpoint and safety analysis of a randomized German-French cooperative phase III trial comparing the efficacy of early versus deferred FCR therapy in treatment-naïve Binet stage A CLL patients with a high risk of disease progression. Risk assessment was performed using 4 prognostic markers: Lymphocyte doubling time <12 months, serum thymidine kinase >10 U/L, an unmutated immunoglobulin heavy chain variable region gene (IGHV) status, and presence of unfavorable cytogenetics (del11q, del17p, trisomy 12) by fluorescence-in-situ hybridization. Presence of at least 2 versus less than 2 of these factors defined “high-risk” versus “low-risk” CLL. High-risk CLL patients were further randomized to receive either 6 cycles FCR (HR-FCR) or to be followed by a W&W strategy (HR-W&W). Patients with low-risk CLL were observed only (LR-W&W). Results Between 2005 and 2010, a total of 824 patients was enrolled, 423 patients in 69 centers of the German CLL Study Group and 401 patients in 25 centers of the French Cooperative Group on CLL. The diagnosis of CLL needed to be established no longer than 12 months prior to enrollment and patients were required to present with previously untreated stage Binet A CLL at the time of inclusion. Overall, 800 patients (97.1%) were stratified, 201 of them categorized as high-risk CLL (25.1%). There was no significant difference between high-risk patients from the two study groups regarding common baseline characteristics (e.g., age, sex, comorbidity, immunophenotype) and the distribution of risk factors used for stratification. 100 out of 201 high-risk patients were randomized to receive FCR therapy (HR-FCR), while 101 patients were allocated to the HR-W&W arm. 18 out of 100 patients (18%) withdrew consent for FCR therapy before treatment was started. 71 (86.6%) of 82 treated patients completed ≥4 cycles. The most common of 228 CTC grade III/IV adverse events reported within 12 months after treatment initiation were hematotoxicity (73.2% of patients) and infections (19.5% of patients). Three patients (3.7%) developed fatal CTC grade V infections (2 septic bacteremias, 1 of them with pulmonary aspergillosis; 1 encephalitis). Out of 79 patients available for response assessment until month 12 after treatment start, 76 showed a complete or partial remission (ORR 96.2%), 2 patients had stable disease (2.5%) and 1 patient had progressed (1.3%). After a median follow up of 46 months (range 0-88 months), HR-FCR patients demonstrated a significantly improved event-free survival (EFS) compared to HR-W&W patients (median EFS not reached versus 24.5 months, respectively, P<0.0001, Fig. 1). Overall survival was not significantly different between HR-FCR and HR-W&W with 181 high-risk patients (90%) being alive at last follow up. Both, HR-FCR and HR-W&W patients exhibited a significant shorter event-free and overall survival than LR-W&W patients, demonstrating an efficient prognostic segregation of patients by the risk assessment used for this trial (analysis based on the German LR-W&W cohort only, complete German-French LR-W&W data will be presented at the meeting). Conclusion This is the first randomized phase III trial investigating the efficacy of FCR chemoimmunotherapy in early stage CLL. So far, the study has revealed two major results: 1. A combination of clinical and biological factors can be used to identify early stage CLL patients who experience a rapid disease progression with unfavorable outcome, 2. FCR chemoimmunotherapy substantially improves event-free survival in early stage high-risk CLL. Disclosures: Langerbeins: Roche: travel grants Other.

Purpose The benefit of high-dose chemotherapy with autologous stem-cell transplantation (ASCT) as first-line treatment in patients with diffuse large B-cell lymphomas is still a matter of debate. To address this point, we designed a randomized phase III trial to compare rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP)-14 (eight cycles) with rituximab plus high-dose sequential chemotherapy (R-HDS) with ASCT. Patients and Methods From June 2005 to June 2011, 246 high-risk patients with a high-intermediate (56%) or high (44%) International Prognostic Index score were randomly assigned to the R-CHOP or R-HDS arm, and 235 were analyzed by intent to treat. The primary efficacy end point of the study was 3-year event-free survival, and results were analyzed on an intent-to-treat basis. Results Clinical response (complete response, 78% v 76%; partial response, 5% v 9%) and failures (no response, 15% v 11%; and early treatment-related mortality, 2% v 3%) were similar after R-CHOP versus R-HDS, respectively. After a median follow-up of 5 years, the 3-year event-free survival was 62% versus 65% ( P = .83). At 3 years, compared with the R-CHOP arm, the R-HDS arm had better disease-free survival (79% v 91%, respectively; P = .034), but this subsequently vanished because of late-occurring treatment-related deaths. No difference was detected in terms of progression-free survival (65% v 75%, respectively; P = .12), or overall survival (74% v 77%, respectively; P = .64). Significantly higher hematologic toxicity ( P < .001) and more infectious complications ( P < .001) were observed in the R-HDS arm. Conclusion In this study, front-line intensive R-HDS chemotherapy with ASCT did not improve the outcome of high-risk patients with diffuse large B-cell lymphomas.

Abstract Over the last 14 years, at our Institute, we have used the NCI 89-C-41 protocol designed by I. Magrath in children and adolescents with small non-cleaved cell (SNCL) and large B-cell (LBCL) lymphomas. In the 1996 paper (J Clin Oncol 1996, 14: 925–34), Magrath et al reported an event-free survival of 92% at 2 years, in adults and children with SNCL. In this protocol, patients with a single extra-abdominal mass or completely resected abdominal disease and LDH <350 IU/L are classified as low-risk; all other patients are defined as high-risk. Low-risk patients receive 3 cycles of the CODOX-M regimen, a combination of cyclophosphamide, doxorubicin, prednisone, vincristine, high-dose methotrexate and intrathecal therapy. High-risk patients receive 4 alternating CODOX-M and IVAC regimens. The IVAC protocol includes ifosfamide, etoposide, high-dose cytarabine and intrathecal methotrexate. We describe hereby the results obtained in 35 patients younger than 21 years with SNCL and LCBL, seronegative for the HIV, treated with the NCI 89-C-41 protocol between September 1989 and March 2003 at our Institute. Median age at presentation was 12.1 years, ranging form 2.6 to 21 years. Thirty patients had SNCL and 5 LBCL. According to Murphy’s staging system, 17 were classified as stage II, 9 as stage III and 9 as stage IV (all with bone marrow involvement that was >25% in 3; 1 with associated CNS disease). Two patients were defined as low risk, while 33 were high-risk. The CNS+ patient received additional IT therapy. G-CSF was given in case of neutropenia associated to severe infections. Thirty-two of the 35 patients (91%) achieved a CR. The remaining 3 patients (SNCL, stages II, III and IV) obtained a PR after the first 2 cycles, but the disease rapidly progressed and led to death in all 3. One patient with stage IV SNCL died in CR of fungal meningitis, during the fourth cycle neutropenia. Three complete responders (SNCL, stage III) relapsed after 2, 2 and 33 months from the end of therapy. Only 1 of them is alive and well in second CR after a stem cell transplant. A life-threatening tumor lysis syndrome was observed in 2 patients; metabolic alterations caused seizures in 1 of them that resolved without sequelae. The hematological toxicity was acceptable; in low-risk patients no thrombocytopenias were observed and neutropenia lasted from 0 to 3 days. For high-risk patients, the median time to PMN >0.5 x 109/L after each cycle was 7, 6, 6 and 6 days (range 0–19), respectively, and to PLTS >50 x 109/L was 6 days (range 0–36). Infections were observed only in high-risk patients with 13 bacterial sepsis, 1 disseminated fungal infection and 12 localized infections. Mucositis (WHO >2) was the main extra-hematological side-effect occurring usually after the CODOX-M regimen; transient peripheral neuropathy occurred in 4 patients after the CODOX-M cycle. No acute and late liver, pulmonary and cardiac toxicities were registered. The 7-years overall survival and event free-survival are 83 and 80%. The results of our study indicate that the NCI 89-C-41 protocol, originally designed for SNCL patients, has confirmed its feasibility and documented its long-term efficacy in a series of children and adolescents with both SNCL and LBCL managed at a single center and with a median follow-up extended to 10 years.

Purpose To investigate whether response to induction therapy, evaluated by metaiodobenzylguanadine (MIBG) and bone scintigraphy, correlates with event-free survival (EFS) in children with high-risk neuroblastoma (NB). Patients and Methods Twenty-nine high-risk NB patients were treated prospectively with an intensive induction regimen and consolidated with three cycles of high-dose therapy with peripheral blood stem-cell rescue. The scintigraphic response was evaluated by MIBG and bone scans using a semi-quantitative scoring system. The prognostic significance of the imaging scores at diagnosis and following induction therapy was evaluated. Results A trend associating worse 4-year EFS rates for patients with versus without osteomedullary uptake on MIBG scintigraphs at diagnosis was seen (35% ± 11% v 80% ± 18%, respectively; P = .13). Similarly, patients with positive bone scans at diagnosis had worse EFS than those with negative scans, although the difference did not receive statistical significance (34% ± 10% v 83% ± 15%, respectively; P = .06). However, significantly worse EFS was observed in patients with a postinduction MIBG score of ≥ 3 compared to those with scores of less than 3 (0% v 58% ± 11%; P = .002). There was no correlation between bone scan scores and outcome following induction therapy. Conclusion MIBG scores ≥ 3 following induction therapy identifies a subset of NB patients who are likely to relapse following three cycles of high-dose therapy with peripheral blood stem-cell rescue, local radiotherapy, and 13-cis-retinoic acid. Alternative therapeutic strategies should be considered for patients with a poor response to induction therapy.

Despite aggressive treatment, the prognosis of high-risk NB patients is still poor. This retrospective study investigated the benefits of metronomic maintenance treatment (MT) in high-risk NB patients without ASCT or GD2 antibody therapy. Patients aged ≤ 21 years with newly diagnosed high-risk NB were included. Patients with complete/very good partial remission (CR/VGPR/PR) to conventional treatment received, or not, oral metronomic MT for 1 year. Two hundred and seventeen high-risk NB patients were enrolled. One hundred and eighty-five (85%) had a CR/VGPR/PR to conventional treatment, of the patients with stage 4, 106 receiving and 61 not receiving oral metronomic MT, and the 3-year event-free survival (EFS) rate was 42.5 ± 5.1% and 29.6 ± 6%, respectively (p = 0.017), and overall survival (OS) rate was 71.1 ± 4.7% and 59.4 ± 6.4%, respectively (p = 0.022). A total of 117 high-risk patients with oral metronomic MT had EFS rate of 42.7 ± 4.8%. The toxicity of MT was mild. For high-risk NB patients without ASCT or anti-GD2 antibody therapy, stage 4, MYCN amplication and patients with stage 4 not receiving oral metronomic MT after CR/VGPR/PR were independent adverse prognostic factors. Oral metronomic MT can improve survival in high-risk NB patients in CR/VGPR/PR without ASCT or anti-GD2 antibodies therapy.

Abstract Forty patients with refractory Hodgkin's disease (24 patients) or non- Hodgkin's lymphoma (16 patients) who were considered for high-dose therapy but not for autologous bone marrow transplantation (ABMT) due to BM metastases, previous pelvic irradiation, a history of marrow involvement by tumor or hypocellular marrow in conventional harvest sites received high-dose therapy and autologous peripheral blood (PB) hematopoietic stem cell transplantation. Disappearance of circulating neutrophils and development of RBC and platelet transfusion-dependence was followed, in the evaluable patients, by reappearance of 0.5 x 10(9)/L circulating granulocytes and sufficient platelets to obviate the need for platelet transfusions at a median of 25 days after transplantation. Twenty-three patients experienced a clinical complete remission (CR). The projected 2-year event-free survival was 24% for all 40 patients and 49% for the non-Hodgkin's lymphoma patients. The projected 18-month event-free survival for the Hodgkin's disease patients was 15%. PB stem cell transplantation provided an opportunity to administer high-dose salvage therapy to patients with refractory lymphoma who otherwise were not candidates for such therapy. For some of those patients, the high-dose therapy produced prolonged survival, free of tumor progression.

Abstract Here we evaluated whether sequential high-dose chemotherapy (sHD) increased the early complete remission (CR) rate in acute myelogenous leukemia (AML) compared with standard-intensity idarubicin-cytarabine-etoposide (ICE) chemotherapy. This study enrolled 574 patients (age, 16-73 years; median, 52 years) who were randomly assigned to ICE (n = 286 evaluable) or sHD (2 weekly 3-day blocks with cytarabine 2 g/m2 twice a day for 2 days plus idarubicin; n = 286 evaluable). Responsive patients were risk-stratified for a second randomization. Standard-risk patients received autograft or repetitive blood stem cell-supported high-dose courses. High-risk patients (and standard-risk patients not mobilizing stem cells) underwent allotransplantation. CR rates after 2 induction courses were comparable between ICE (80.8%) and sHD (83.6%; P = .38). sHD yielded a higher single-induction CR rate (69.2% vs 81.5%; P = .0007) with lower resistance risk (P &lt; .0001), comparable mortality (P = .39), and improved 5-year overall survival (39% vs 49%; P = .045) and relapse-free survival (36% vs 48%; P = .028), despite greater hematotoxicity delaying or reducing consolidation blocks. sHD improved the early CR rate in high-risk AML (odds ratio, 0.48; 95% confidence interval [CI], 0.31-0.74; P = .0008) and in patients aged 60 years and less with de novo AML (odds ratio, 0.46; 95% CI, 0.27-0.78; P = .003), and also improved overall/relapse-free survival in the latter group (hazard ratio, 0.70; 95% CI, 0.52-0.94; P = .01), in standard-risk AML, and postallograft (hazard ratio, 0.61; 95% CI, 0.39-0.96; P = .03). sHD was feasible, effectively achieved rapid CR, and improved outcomes in AML subsets.

Abstract The conventional treatment of chronic myeloid leukemia (CML) in early chronic phase (ECP) is imatinib 400 mg daily. The estimated rates of major (MCgR) and complete cytogenetic response (CCgR) at 42 months are 91% and 84%, respectively (IRIS Trial - F Guilhot, ASH 2004), with a survival free from accelerated and blastic phase of 84%. The rates of CCgR are significantly different according to Sokal score, being 91%, 84% and 69% for low, intermediate and high risk categories. Phase I and II trials of imatinib have clearly shown a dose-response effect; more importantly, a single center phase II trial of imatinib 800 mg in ECP showed significantly better results vs standard dose, in terms of CCgR (90% vs 74%) and of complete molecular response (28% vs 7% at 18 months) [H. Kantarjian et al, Blood 103 (8), 2004]. The GIMEMA (Gruppo Italiano Malattie Ematologiche dell’Adulto) CML WP is conducting a phase II trial of imatinib 800 mg in intermediate Sokal risk in ECP (trial CML/021). Overall, 89 pts (mean age 53 yrs) have been enrolled. Fourty-four patients completed 6 months of treatment: the complete hematological response rate is 100%; the MCgR and CCgR are 90% and 81%, respectively. The 6 months CCgR rate of this trial parallels the IRIS trial one in intermediate risk cases (84%), with a much shorter treatment period. The major molecular response rate at 6 months (RTQ-PCR as ratio BCR-ABL/ABL) is 56% (cut-off ≤ 0.12%) or 41% (cut-off ≤0.05%). The compliance to the treatment improved time by time, being 47% the patients receiving ≥ 80% of the scheduled dose between months 1–3 and 60% between months 4 - 6. A second project, exploring imatinib high dose, is reserved to high risk cases: a multinational working group, within the frame of Leukemianet CML WP, is conducting a phase III randomized trial (1:1) of imatinib 400 mg vs 800 mg in high Sokal risk in ECP. By July 31, 2005, 80 patients have been enrolled: GIMEMA CML WP (44 pts), Nordic Countries - Sweden, Denmark, Norway and Finland (25 pts), Turkey (10 pts) and Israel (1 pt).
