In an effort to increase the proportion of patients with acute myeloid leukemia (AML) remaining in continued complete remission (CCR), we administered intensive postremission consolidation therapy with high-dose cytarabine (Ara-C) and daunorubicin. Eighty-seven patients, with a median age of 38 years (range, 7 to 71), received consolidation therapy after first complete remission was obtained with standard induction chemotherapy that included conventional doses of Ara-C. Consolidation therapy consisted of from one to three cycles of high-dose Ara-C (3 g/m2 intravenously [IV] over 1 hour every 12 hours for 12 doses) followed by daunorubicin (30 mg/m2/d IV bolus for 3 days). After completion of the high-dose Ara-C and daunorubicin, no further therapy was administered. Myelosuppression encountered with consolidation resulted in a median duration of neutropenia and thrombocytopenia of 3 weeks. Four patients (5%) died during consolidation due to infection and/or hemorrhage; 59% of patients experienced severe but nonfatal infectious or extramedullary organ toxicity. With a median follow-up of more than 3.5 years from diagnosis, the proportion of patients, by Kaplan-Meier product-limit estimate, remaining in CCR is 49% (95% confidence limits, 37% to 61%). In a Cox multivariate analysis, only age significantly (P less than .001) influenced the probability of remaining in CCR. The probability of remaining in CCR was 83%, 50%, and 23% for age groups of 25 or less, 26 to 45, and more than 45 years, respectively. These survival curves all have stable long-term plateaus, suggesting cure. In this study, the administration of brief, intensive nonmarrow ablative chemotherapy resulted in a large proportion of patients with AML remaining in CCR, results similar to those reported with allogeneic bone marrow transplantation. Relapse of acute leukemia was still the major reason for therapy failure, suggesting that more effective or additional postremission therapy will be required to further improve the likelihood of cure especially for older patients.

Purpose SWOG S0016 was a phase III randomized study that compared the safety and efficacy of R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone) with CHOP-RIT (CHOP followed by consolidation with iodine-133–tositumomab radioimmunotherapy) for previously untreated patients with follicular lymphoma. Understanding the long-term outcome of patients provides a benchmark for novel treatment regimens for FL. Patients and Methods Between 2001 and 2008, 531 previously untreated patients with FL were randomly assigned to receive either six cycles of R-CHOP or six cycles of CHOP-RIT. Patients with advanced-stage disease (bulky stage II, III, or IV) of any pathologic grade (1, 2, or 3) were eligible. Results After a median follow-up of 10.3 years, 10-year estimates of progression-free and overall survival were 49% and 78% among all patients, respectively. Patients in the CHOP-RIT arm had significantly better 10-year progression-free survival compared with patients in the R-CHOP arm (56% v 42%; P = .01), but 10-year overall survival was not different between the two arms (75% v 81%; P = .13). There was no significant difference between the CHOP-RIT and R-CHOP arms in regard to incidence of second malignancies (15.1% v 16.1%; P = .81) or myelodysplastic syndrome or acute myeloid leukemia (4.9% v 1.8%; P = .058). The estimated 10-year cumulative incidences of death resulting from second malignancies were not different (7.1% v 3.2%; P = .16), but cumulative incidence of death resulting from myelodysplastic syndrome or acute myeloid leukemia was higher in the CHOP-RIT arm compared with the R-CHOP arm (4% v 0.9%; P = .02). Conclusion Given these outstanding outcomes, immunochemotherapy should remain the standard induction approach for patients with high-risk FL until long-term follow-up of alternative approaches demonstrates superiority.

Abstract Background: The results of salvage chemotherapy for patient with refractory or relapsed acute myeloid leukemia(AML) have been generally disappointing with low response rates and occasional long-term survivors in most studies. Since therapeutic failure seems to be inevitable in the great majority of these patients, development of more effective salvage therapy is warranted. Recent approaches to the treatment of previously treated AML generally involved the use of cytarabine in intermediate or high-dose alone or in association with new intercalating agents, such as amsacrine, mitoxantrone or idarubicin, etoposide, or asparaginase. Methods: A single course of mitoxantrone 6 mg/m2 intravenous (IV) bolus, etoposide 80 mg/m2 IV for 1 hour, and cytarabine (Ara-C) 1g/m2 IV for 6 hours daily for 6 days (MEC), has been proposed as a salvage regimen. Between October 1998 and May 2005, thirty refractory/relapsed AML patients have been treated by MEC salvage chemotherapy. Twenty two patients were in relapse and eight patients were refractory after conventional induction chemotherapy including cytarabine and idarubicin or mitoxantrone. Two patient were in relapse after allogenous hematopoietic stem cell transplantation(SCT). Results: Complete remission(CR) was obtained in 12 of 30 patients(40%) and 3 of 30(10%) died during salvage treatment: 2 due to intracranial hemorrhage and 1 due to fungemia sepsis. After CR achievement, 5 patients received consolidation chemotherapy. Two patients with an HLA-identical sibling donor underwent allogeneic SCT, and one patient received autologous SCT. Severe myelosuppression was observed in all patients resulting in fever or documented infections in 90% of patients. Nonhematologic toxicity was minimal. At the time of analysis, 9 of 11 patients who achieved CR have relapsed. Median disease-free survival was 12 months. Median overall survival was 13.5 months. There were only two longterm remitters. Several clinicolaboratory and treatment-related variables were analyzed to determine their prognostic significance for CR achievement, duration of CR, overall survival. Conclusions: Our results suggest that MEC combination chemotherapy might induce CR in a patient with refractory or relapsed AML, although new agents or new therapeutic strategies should be required for long term remission.

Abstract Abstract 132 Late relapse in acute myeloid leukemia (AML) has been infrequently studied and variably defined in the literature. Two series have shown that late relapse of AML ≥5 years after first complete remission (CR1) is uncommon, with rates of 1.19–3% (Medeiros et al, Leuk Lymphoma 2007; Verma et al, Leuk Lymphoma 2010). We searched the long-term data available on 784 adults (<60 years-old) who were treated on 1 of 4 ECOG clinical trials (E3483, PC486, E3489, or E1900) and achieved CR1 for reports of late relapse (defined as recurrence of AML ≥3 years after CR1). Median follow-up for the 553 patients last known alive was 11.1 years. The longest median follow-up was 17.2 years on trial PC486. Outcomes We found that 11 patients (1.4%) relapsed late; of these, 2 were treated on E3483, 1 on PC486, 5 on E3489, and 3 on E1900. Seven patients with late relapse died from their disease and 4 were living at last known follow-up. Only 1 patient (0.13%) had recurrence of AML ≥5 years after achieving CR1. It is possible that more late relapses will occur on E1900 (a more recent study with ongoing follow-up). All of these trials except E3483 treated some patients with autologous hematopoietic cell transplantation (autoHCT) as part of post remission therapy. On PC486, no post remission consolidation chemotherapy was administered before autoHCT. Ninety-eight total patients on E3489 and PC486 received autoHCT, and there were no late relapses; on E1900, 2 of the 141 patients treated with autoHCT developed late relapse. No patients who underwent allogeneic (allo) HCT in CR1 experienced late relapse on any of the 4 clinical trials. Nine of the 11 patients with late relapse did not undergo HCT; of these, 5 were consolidated with high-dose cytarabine, 2 received maintenance with low-dose cytarabine and 6-thioguanine, and 2 received unknown post remission therapy. Of the 3 patients with late relapse on E1900, 2 received standard-dose and 1 high-dose daunorubicin with induction. Conclusions Across all 4 trials, only 2 of the 239 patients (0.8%) treated with post remission autoHCT experienced late relapse of AML (≥3 years after CR1), which reinforces previously published data that late relapse after autoHCT is uncommon (Cassileth et al, J Clin Oncol 1993). Furthermore, of the 35 patients treated with autoHCT on PC486, 11 relapsed early and no patients relapsed late, suggesting that post remission chemotherapy may not be necessary before autoHCT. Based on this large AML cohort of nearly 800 patients with long-term follow-up, patients who remain in CCR for at least 3 years have a very low risk of relapse and can be considered cured of their disease. Moreover, given that recurrent AML was extremely rare after 5 years or more of CCR (<0.2%), the risk of therapy-related AML from contemporary induction and post remission strategies including HCT appears to be minimal.
