Abstract PURPOSE. To assess the long-term outcome of AML patients (pts) in complete remission (CR) after a phase III study which compared the effect of post-consolidation immunotherapy with interleukin-2 (IL-2) and histamine dihydrochloride (HDC) on leukemia-free survival (LFS) and overall survival (OS). PATIENTS & METHODS. A multi-national, randomized, open-label, phase III study which recruited 261 AML pts in first remission (CR1) and 59 in subsequent remission (CR>1) was conducted between June 1998 and October 2000. Pts were enrolled after after termination of consolidation therapy, stratified by country and CR status, and randomized to either treatment or no treatment (standard of care, control). Forty-one % of pts were >60 yrs (median 57), and 54% were males. Study arms were balanced for known prognostic factors. Two patient populations were studied, i.e. all pts randomized (ITT population; n=320) and pts in CR1. The treatment was self-administered at home and included ten 3-week courses of low-dose IL-2 (aldesleukin, Chiron Corp) 18 000 U/kg sc bid, plus HDC (EpiCept) 0.5 mg sc bid. Cycles 1–3 comprised 3 wks of treatment and 3 wks of rest, whereas in cycles 4–10 the rest periods were 6 wks. As reported previously (Blood2006; 108:88), the trial met the primary endpoint of prolonged leukemia-free survival (LFS) for all pts randomized (p=0.008 in favor of the treatment arm) at a median of 46 months of follow-up. The present long-term assessment of efficacy was conducted in August 2006, 30 months after the lock of the original data base. RESULTS. Follow-up forms were retrieved from 86% (n=107; 59 HDC/IL-2 recipients, 48 no treatment,) of the 124 pts pts who were alive at original study cut-off. In the long-term analysis, median LFS in the ITT population was 11 and 8.8 months in HDC/IL-2 and no treatment groups, respectively. In the CR1 population, median LFS was 15 and 9.7 months in HDC/IL-2 and no treatment groups, respectively. The benefit of treatment both for the ITT population (p=0.017) and in CR1 pts (p=0.026) was demonstrated by log-rank testing. Kaplan-Meier (KM) estimates for LFS at 60 months revealed a trend in favor of the treatment group in the ITT population (29.6 vs 20.6%; p=0.065) and a significant difference in the CR1 population (34.4 vs 21.7%, p=0.024). The median OS of CR 1 pts were 44 months (HDC/IL-2) and 28 months (no treatment), but the difference did not attain statistical significance (log rank test: p=0.22; KM estimate at 60 months: p=0.07). CONCLUSION. Post-consolidation immunotherapy with HDC/IL-2 results in significant long-term improvement of LFS.

Purpose There is no consensus on the optimal systemic treatment of patients with extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue. The IELSG-19 phase III study, to our knowledge, was the first such study to address the question of first-line treatment in a randomized trial. Patients and Methods Eligible patients were initially randomly assigned (1:1 ratio) to receive either chlorambucil monotherapy (6 mg/m2/d orally on weeks 1 to 6, 9 to 10, 13 to 14, 17 to 18, and 21 to 22) or a combination of chlorambucil (same schedule as above) and rituximab (375 mg/m2 intravenously on day 1 of weeks 1, 2, 3, 4, 9, 13, 17, and 21). After the planned enrollment of 252 patients, the protocol was amended to continue with a three-arm design (1:1:6 ratio), with a new arm that included rituximab alone (same schedule as the combination arm) and with a final sample size of 454 patients. The main end point was event-free survival (EFS). Analysis of chlorambucil versus the combination arm was performed and reported separately before any analysis of the third arm. Results At a median follow-up of 7.4 years, addition of rituximab to chlorambucil led to significantly better EFS (hazard ratio, 0.54; 95% CI, 0.38 to 0.77). EFS at 5 years was 51% (95% CI, 42 to 60) with chlorambucil alone, 50% (95% CI, 42 to 59) with rituximab alone, and 68% (95% CI, 60 to 76) with the combination ( P = .0009). Progression-free survival was also significantly better with the combination ( P = .0119). Five-year overall survival was approximately 90% in each arm. All treatments were well tolerated. No unexpected toxicities were recorded. Conclusion Rituximab in combination with chlorambucil demonstrated superior efficacy in mucosa-associated lymphoid tissue lymphoma; however, improvements in EFS and progression-free survival did not translate into longer overall survival.

2008b Background: Anaplastic oligodendrogliomas, pure (AO) and mixed (AOA), are chemosensitive tumors, especially if co-deleted for chromosomes 1p and 19q, but whether addition of CT to RT prolongs overall survival (OS), is unknown. Methods: In the RTOG 9402 Phase III trial, patients (pts) with AO/AOA were randomly assigned to PCV [procarbazine, CCNU (lomustine) and vincristine] followed by immediate RT vs. immediate RT alone. Early analysis showed no OS benefit for the PCV+RT group but combined therapy was associated with a longer progression-free survival (PFS). It also showed that the finding of 1p/19q co-deletion was associated with a longer OS independent of treatment. The current analysis has a median follow up of 11.3 years (yrs). Results: Two hundred ninety-one patients were randomized, 148 to PCV+RT and 143 to RT. PCV+RT was associated with longer PFS [2.5 vs. 1.7 yrs, hazard ratio (HR) 0.68, 95% confidence interval (CI) (0.53, 0.88), P = 0.003] and the 1p/19q co-deletion with a longer Median Survival Time (MST) [8.7 vs. 2.7 yrs, HR 0.41, 95% CI (0.30, 0.55), P < 0.001]. For the entire cohort, there was no difference in MST by treatment [4.6 yrs for PCV+RT vs. 4.7 yrs for RT, HR 0.79, 95% CI (0.60, 1.04), P = 0.1]. However, patients with 1p/19q co-deleted tumors lived much longer after PCV+RT (n = 59) than after RT (n = 67) [14.7 vs. 7.3 yrs, HR 0.59, 95% CI (0.37, 0.95), P = 0.03]. There was no difference in MST by treatment in pts without the 1p/19q co-deletion [n=137; 2.6 vs. 2.7 yrs, HR 0.85, 95% CI (0.58, 1.23), P = 0.39]. Re-operation rates upon progression were similar between treatment arms in co-deleted pts (43%, PCV+RT vs. 54%, RT) but salvage CT rates were higher in the RT arm [57% vs. 81% (P = 0.04)]. Conclusions: PCV followed by immediate RT was a highly effective therapy for patients with 1p/19q co-deleted AO/AOA. In this setting, 1p/19q co-deletion was both prognostic and predictive, and the early PFS benefit in co-deleted cases was a harbinger of their longer OS.

4014 Background: In a previous phase II study the ELFE regimen resulted to be active and well tolerated for the treatment of advanced GC (Am J Clin Oncol 22:262;1999). Based on this background the G.O.I.M. conducted a randomised phase III study (trial 9602) to evaluate efficacy and toxicity of ELFE regimen as adjuvant therapy for radically resected GC patients (pts). Methods: All enrolled pts underwent total or subtotal gastrectomy with at least a D1 lymphoadenectomy. After stratification for nodal involvement (N+ vs N-) pts were randomised to follow-up alone (116 pts) or 6 cycles of ELFE regimen ( EPI 60mg/m2 d1, LV100 mg/m2 d 1–5, 5FU 375 mg/m2 d 1–5, VP-16 100 mg/m2 d1–3, every 3 weeks). Results: From June 1997 to June 2001, 228 pts with stage IB-IIIB GC were enrolled. Pts characteristics were: median age 63 yrs (29–70); total gastrectomy 148 pts; N+ 163 pts; PS 0–1 according ECOG scale 210. A total number of 638 cycles were delivered with a median number of 5/pt. During chemotherapy, the most frequent G3–4 side-effects graded according to NCI-CTC included alopecia (32%), neutropenia (26%), diarrhea (26%), nausea/emesis (17%), thrombocytopenia (12%) and stomatitis (11%). With a median follow-up of 60 months, the 5-years overall survival was 48% in the treatment arm and 43.5% in the control arm ( p=0.610); the 5-years disease-free survival was 44% in the treatment arm and 39% in the control arm ( p=0.305). Between patients with positive nodes the 5-years overall survival was 41% in the treatment arm and 34% in the control arm( p=0.068), while the 5-years disease-free survival was 39% in the treatment arm and 31% in the control arm (p=0.052). Multivariate analysis showed TNM stage as the only covariate that was independently associated with overall and disease-free survival. Conclusions: In radically resected GC adjuvantELFE chemotherapy produces an absolute difference in overall survival and disease-free survival at 5 years respectively of 4.5% and 5%, but this advantage was not statistically significant. No significant financial relationships to disclose.

455 Background: The POUT trial (CRUK/11/027; NCT01993979) previously reported (with median follow-up 30.3 months) that adjuvant chemotherapy improves disease free survival (DFS) for patients (pts) with histologically confirmed pT2-T4 N0-3 M0 UTUC. Here we present results of a pre-planned analysis updating the primary endpoint and reporting key secondary endpoints including overall survival. Methods: 261 pts with UTUC were enrolled following nephro-ureterectomy and randomised (1:1) to 4 cycles of gemcitabine-cisplatin (gemcitabine-carboplatin if GFR 30-49ml/min) or surveillance with subsequent chemotherapy if required. Pts had 6 monthly imaging and cystoscopy for 2 years, then annually to 5 years. Toxicity was assessed by CTCAE v4. Primary endpoint was DFS. Secondary endpoints included metastasis free survival (MFS), overall survival (OS), toxicity and patient reported quality of life (QoL). The trial closed to recruitment early on advice of the independent data monitoring committee due to evidence of efficacy. Time-to-event endpoints are analysed (intention-to-treat) by Cox proportional hazard models. Unadjusted and adjusted (by nodal status, planned chemotherapy type, microscopic margin status, pathological stage) hazard ratios (HR, < 1 favouring chemotherapy) are reported. Results: From May 2012 to Nov 2017, 261 pts were recruited (129 surveillance; 132 chemotherapy) at 56 UK centres. One participant withdrew consent for data usage and was excluded from analyses. Pts had median age 69 years (range 37-88), 28% pT2, 66% pT3; 91% pN0. To 09/09/2020, median follow up was 48.1 months (IQR: 36.0-60.1). The unadjusted/adjusted HR for DFS was 0.48 (95% CI: 0.33-0.71; p = 0.0003) / 0.50 (95%CI: 0.34-0.75; p = 0.001), and for MFS was 0.52 (95% CI: 0.35-0.77; p = 0.001) / 0.54 (95% CI: 0.36-0.81; p = 0.002). 93/260 (35.8%) pts have died (52/129 [40.3%] surveillance and 41/131 [31.3%] chemotherapy). Chemotherapy conferred a non-statistically significant 28% reduction in relative risk of death (HR = 0.72, 95% CI: 0.47-1.08; p = 0.11; adjusted HR = 0.79, 95% CI: 0.52-1.19; p = 0.26). 3 year OS was surveillance: 67% (95% CI: 58-74%; chemotherapy: 79% (71%-85%). There was no evidence of long-term toxicity associated with chemotherapy (Wilcoxon rank-sum test p-value for worst grade post-6 months = 0.32). Most common grade 2+ adverse events were hypertension (25/240 [10.4%]), lethargy (25/240 [10.4%]) and hearing loss (13/240 [5.4%]). There was no evidence of statistically or clinically relevant differences in QoL. 12 months after treatment (EORTC Q30 global health status mean difference 4.1 and 4.8 at 12 and 24 months respectively in favour of chemotherapy). Conclusions: With additional follow-up, the previously reported DFS benefit for chemotherapy was maintained with no detrimental long-term toxicity. No statistically significant improvement in OS was observed. Clinical trial information: NCT01993979.

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.

PURPOSE: We conducted a phase II pilot study of dose-intensive adjuvant chemotherapy with doxorubicin followed sequentially by high-dose cyclophosphamide to determine the safety and feasibility of this dose-dense treatment and to estimate the disease-free and overall survival in breast cancer patients with four or more involved axillary lymph nodes. PATIENTS AND METHODS: Seventy-three patients received adjuvant treatment with four cycles of doxorubicin 75 mg/m2 as an intravenous bolus every 21 days, followed by three cycles of cyclophosphamide 3,000 mg/m2 every 14 days with granulocyte colony-stimulating factor support. RESULTS: Seventy-one patients were assessable, and all but two completed all planned chemotherapy. There was no treatment-related mortality. The most common toxicity was neutropenic fever, which occurred in 39% of patients. Median disease-free survival is 66 months (95% confidence interval, 34 to 98 months), and median overall survival has not yet been reached. At 5 years of follow-up, the disease-free survival is 51.7%, and overall survival is 60.0%. There is no long-term treatment-related toxicity, and no cases of acute myelogenous leukemia or myelodysplastic syndrome have been observed. CONCLUSION: Our pilot study of doxorubicin followed by cyclophosphamide demonstrates the safety and feasibility of the sequential dose-dense plan. Long-term follow-up, although noncomparative, is promising. However, this regimen is associated with a higher incidence of toxicity (and also higher costs) than the standard dose and schedule of doxorubicin and cyclophosphamide, and therefore it should not be used as conventional therapy in the absence of demonstrated improvement of outcome. Randomized trials testing the dose-dense approach have been completed but not yet reported. Because the sequential plan can decrease overlapping toxicities, it is an appropriate platform for the addition of newer active agents, such as taxanes or monoclonal antibodies.

Abstract Background: Histamine dihydrochloride (HDC) potentiates immune-based therapies by protecting pivotal anti-neoplastic lymphocytes from phagocyte-induced suppression. Previous results in AML indicated that post-consolidation treatment with HDC and low-dose interleukin-2 (IL-2) is safe and feasible, and that the combination may prolong leukemia-free survival (LFS). Aims: The primary objective was to determine if post-consolidation treatment with IL-2 and HDC could improve LFS for AML pts in complete remission (CR). Secondary objectives included overall survival (OS), LFS in CR1 and CR>1 subgroups, and safety. Methods: This international, randomized, open-label, phase III study was conducted at 92 centers. From June 1998 to October 2000, 320 AML pts [148 females, 172 males, median age 57 (18–84) yrs] were enrolled in CR after completion of standard consolidation therapy. Pts were stratified by CR1 or CR>1 and randomized to either treatment (n=160) or no treatment (control, n=160) arms. The treatment was self-administered at home and included 10 cycles of low-dose IL-2 (aldesleukin, Chiron Corp) 18 000 U/kg, sc bid plus HDC (Maxim Pharmaceuticals) 0.5 mg sc bid. For cycles 1–3, each cycle comprised 3 wks of treatment and 3 wks of rest, whereas in cycles 4–10 the rest periods were 6 wks. The study arms were well balanced with respect to age, sex, karyotype-based risk, time from CR to inclusion and frequency of secondary leukemia. Pts were followed for relapse and survival using an identical assessment schedule until 3 yrs after last enrollment. All efficacy analyses were intent-to-treat. Results: The median follow-up of living pts was 46 months. For the primary endpoint, treatment with HDC/IL-2 increased LFS in the entire study population (CR1/CR>1, n=320, p=0.026 stratified log-rank test). There was no significant difference in OS (p=0.33). In the analysis of pre-stratified subgroups, one pt was excluded. For CR1 pts (n=262), HDC/IL-2 significantly improved LFS (p=0.011, log-rank test), with 3-year Kaplan-Meier estimates of 26% (control group) and 40% (treatment group). The difference in OS did not reach significance (p=0.16). For CR>1 pts (n=57), outcome was not affected by treatment. Side effects attributable to IL-2 included fever and local inflammatory reactions. HDC treatment induced symptoms of transient vasodilatation. Serious adverse events occurred in approximately 20% of pts in both groups. There were no treatment-related deaths. Conclusions: For AML pts in CR, post-consolidation therapy with HDC and IL-2 was safe and significantly improved LFS compared to standard of care. The benefit observed of HDC/IL-2 treatment appears to be explained by a reduction of relapses in CR1 pts.
