Abstract In this randomized multicenter study of 136 patients, 6 courses of CHOP (cyclo-phosphamide/doxorubicin/vincristine/prednisone) followed by rituximab (CHOP-R) were compared with rituximab-supplemented high-dose sequential chemotherapy with autografting (R-HDS) to assess the value of intensified chemo-therapy as a first-line treatment for high-risk follicular lymphoma (FL) after the introduction of monoclonal antibodies. The analysis was intention to treat with event-free survival (EFS) as the primary endpoint. Complete remission (CR) was 62% with CHOP-R and 85% with R-HDS (P < .001). At a median follow-up (MFU) of 51 months, the 4-year EFS was 28% and 61%, respectively (P < .001), with no difference in overall survival (OS). Molecular remission (MR) was achieved in 44% of CHOP-R and 80% of R-HDS patients (P < .001), and was the strongest independent outcome predictor. Patients relapsing after CHOP-R underwent salvage R-HDS in 71% of cases. Salvage R-HDS had an 85% CR rate and a 68% 3-year EFS (MFU, 30 months). We conclude that (1) achieving MR is critical for effective disease control, regardless of which treatment is used; (2) R-HDS ensures superior disease control and molecular outcome than CHOP-R, but no OS improvement; and (3) CHOP-R failures have a good outcome after salvage R-HDS, suggesting that relapsed/refractory FL could be the most appropriate setting for R-HDS–like treatments. This trial was registered at www.clinicaltrials.gov as no. NCT00435955.

AbstractThe purpose of this study is to compare our standard chemotherapy regimen (CHVP [cyclophosphamide, doxorubicin, teniposide, and prednisone]) plus interferon with 4 courses of CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) followed by high-dose therapy with autologous stem cell transplantation (ASCT) in treatment-naive patients with advanced follicular lymphoma. Four hundred one patients were included from July 1994 to March 2001: 209 received 12 cycles of CHVP plus interferon α for 18 months (CHVP-I arm) and 192 received 4 cycles of CHOP followed by high-dose therapy (HDT) with total body irradiation and ASCT (CHOP-HDT arm). Overall response rates were similar in both groups (79% and 78% after induction chemotherapy, respectively). One hundred thirty-one of the 150 patients eligible for HDT underwent transplantation (87%). Intent-to-treat analysis after a median follow-up of 7.5 years showed that there was no difference between the 2 arms for overall survival (P = .53) or event-free survival (P = .11). Patients with a complete response at the end of the induction therapy had a statistically longer event-free survival and overall survival (P = .02 and < .001, respectively). After long-term follow-up, our study showed that there was no statistically significant benefit in favor of first-line high-dose therapy in patients with follicular lymphoma. High-dose therapy should be reserved for relapsing patients.

672 Background: Investigation of high dose chemotherapy (HD-CT) supported by autologous hematopoietic stem cell transplantation compared with standard dose chemotherapy (SD-CT) as adjuvant treatment in patients with primary breast cancer and 10 or more axillary lymph nodes. Methods: Between November 1993 and September 2000 307 patients were randomized to receive the following cycles of Epirubicin (90 mg/m2), Cyclophosphamide (600 mg/m2) intervenously (every 21 days) either HD-CT of Cyclophosphamide (1500 mg/m2), Thiotepa (150 mg/m2) and Mitoxantrone (10 mg/m2) intervenously for 4 consecutive days followed by stem cell transplantation or standard dose chemotherapy SDCT in 3 cycles of Cyclophosphamide (500 mg/m2), Methotrexate (40 mg/m2) and Fluoruracil (600 mg/m2) intervenously on days 1 and 8 every 28 days. The primary end points were event-free survival and overall survival. Results: After a median follow-up of 6.1 years 166 events with respect to event-free survival (SD-CT: 91, HD-CT: 75) and 123 with respect to overall survival (SD-CT: 66 and HD-CT: 57) have been observed. The hazard ratio of HD-CT versus SD-CT is estimated as 0,80, p = 0,15. The hazard ratio for overall survival for high dose chemotherapy versus standard dose chemotherapy is estimated as 0,84, p = 0,33. Analysing the effect of treatment on event-free survival premenopausal patients, patients with tumor grade III and ER-positive patients had a better outcome with HD-CT with an interactive effect of 2.5 and 1.4. The significance was only shown in grade III patients in favour of HD-CT, (p = 0,049). The interactive effect of HD-CT with prognostic factors did not reach significance for overall survival. Conclusion: Even with a follow-up of 6.1 years there was only a trend in favour of high dose chemotherapy with respect to overall survival but without a statistical significance. A proper meta-analysis needs to be undertaken for an evaluation of subgroups of patients which might benefit from this treatment approach. No significant financial relationships to disclose.

Abstract Background: Autologous stem cell transplantation (ASCT) is now considered standard therapy in young patients (<65 years) with multiple myeloma (MM). The Intergroupe Francophone du Myelome conducted a randomized trial of the treatment of MM with high-dose chemotherapy followed by either one or two successive ASCTs. The probabilities of event-free-survival and overall survival were doubled with a double transplant. However, no randomized trial has compared tandem transplant up-front with a strategy including planned second ASCT at relapse or progression. Therefore, we performed a multicenter, sequential, randomized trial designed to assess the optimal timing of a second ASCT. Methods: From May 2003 to April 2006, 140 patients with symptomatic MM (de novo) and less than 60 years of age, were randomly assigned to receive either tandem transplantation up-front (within 6 months of the first transplantation) [Arm A, n=69] or one ASCT followed by a consolidation therapy with thalidomide (day +90, 100 mg/per day during 5 months) [Arm B, n=71]. Patients included in the arm B received a second transplant in case of disease progression on consolidation therapy, or in case of relapse in responders. Clinical characteristics of each group were similar. In both arms of the study, ASCT was preceded by first-line therapy with thalidomide-dexamethasone and subsequent collection of peripheral blood stem cells with high-dose cyclophosphamide (4 g/m2) and G-CSF. Data were analyzed on an intent-to-treat basis. Results: With a median follow-up of 23 months (range: 6–34), the 2-year overall survival was 55% in the arm A and 75% in the arm B. Survival curves were not different (P=0.28, log-rank test). The 2-year event-free survival was 41% in the arm A and 60% in the arm B (P=0.4, log-rank-test). In the arm B, relapse-free survival of ≥ 16 months following the first transplantation was an important predictor of overall survival (p< 0.001). Conclusion: Data from the present study suggest that up-front single ASCT followed by a consolidation therapy with thalidomide and a second ASCT after relapse or progression is a safe and effective global strategy to treat MM patients. Longer follow-up is needed before definite conclusions can be given concerning the optimal timing of second autologous transplantations in patients with MM.

Abstract Clinical trials on different cytarabine doses for treatment of AML provide evidence of a dose response effect, but also for increase toxicity after high dose AraC (HDAC). Pharmacokinetic measurements of cytarabine-triphosphate (AraC-CTP), which is the most relevant cytotoxic metabolite of AraC, have revealed its formation in leukemic cells to be saturated with infusion rates above 250 mg/m2/h, this being significantly lower than used in HDAC schedules. Methods: Based on a pharmacological model and encouraging results of a phase II study we conducted a prospective randomized multicenter clinical trial comparing the effects of two different application modes of AraC in patients up to 60 years with untreated newly diagnosed AML. Patients were randomized to receive AraC at two different infusion rates (IR) during induction and consolidation treatment: arm A/experimental: 1 × 2 g/m2/d AraC over 8 hours (IR 250 mg/m2/h) arm B/standard: 2 × 1 g/m2/d AraC over 3 hours (IR 333 mg/m2/h). Induction and first consolidation consisted of AraC (days 1, 3, 5, 7) in combination with an anthracycline (Idarubicine 12 mg/m2 or Mitoxantrone 10 mg/m2, days 1–3). The final dosage points (AraC day 7 and anthracycline day 3) were excluded from the second consolidation. The third consolidation consisted of either allogeneic or autologous stem cell transplantation or of chemotherapy identical to second consolidation. Results: From 02/97 to 04/02 419 patients were enrolled in the study. The present analysis is based on 361 eligible and evaluable patients with a median follow up of 7 years. CR was reached in 249/361 (69%; 95%CI: 65%–74%) patients. No statistically significant differences were detected between arms A and B with regard to CR-rate (69% vs 69%) or early death rate (11% vs 8%). Hematological recovery of median white blood cell count (WBC) &gt; 109/l and median platelets (plt) &gt; 50 × 109/l revealed no difference between arms A and B after induction (WBC day 22 vs 22, p=0,68; plt day 25 vs 26, p=0,41) and consolidation (WBC day 28 vs 27, p=0,07; plt day 42 vs 40, p= 0,58). The event free survival (EFS) after 5 years is 0,25 ± 0,03 % for all patients with an overall survival of 0,31 ± 0,03 % after 5 years. For the purposes of analysis, the 83 transplant patients (23 allogeneic MRD, 14 allogeneic MUD and 46 autologous) were censored at time of transplant. No statistically significant difference between arms A and B in regard to EFS (0,25 ± 0,04 vs 0,25 ± 0,04, p=0,99), relapse incidence (0,63 ± 0,06 vs 0,60 ± 0,06, p=0,89), overall survival (0,32 ± 0,04 vs 0,30 ± 0,04, p=0,44) and therapy associated mortality (0,18 ± 0,04 vs 0,17 ± 0,03, p=0,95) were detectable after adjustment of prognostic factors. An analysis of risk factors by multivariate cox regression model confirmed cytogenetics at diagnosis to be the most important risk factor for CR rate (p&lt;10−6) and for EFS (p&lt;10−6). Other significant prognostic factors for EFS evaluated in the multivariate analysis were de novo vs secondary AML (p=0,0001), WBC (continuous) (p=0,001), LDH (&gt;1–4 × vs other ULN) (p=0,008) and FAB classification (FAB M0,6,7 vs FAB M1,2,4,5) (p=0,0005). EFS after 5 years shows a significant correlation to cytogenetics (p&lt;10−6) with 0,71±0,1, 0,27±0,05, 0,20±0,06 and 0,03±0,03 for favorable, normal, other and unfavorable cytogenetic karyotype, respectively. Conclusion: We conclude that the application of AraC at the presumptive saturating infusion rate of 250 mg/m2/h results in comparable remission rates, toxicity, event free survival and overall survival as compared to the standard IR with 333 mg/m2/h.

Abstract Background: Novel therapies are required to improve the outcome of patients with AML. New agents are asked to demonstrate an overall survival (OS) benefit before qualifying for FDA approval. The long duration of clinical trials required in order to achieve this endpoint hampers quick evaluation of candidate therapies, including novel agents. Identification of reliable surrogate endpoints for OS in AML is needed. Here we compare the results of therapy for patients with untreated AML ages 16-60 years on the Eastern Cooperative Oncology Group 1900 trial (E1900) of induction chemotherapy followed by consolidation and autologous transplant in order to evaluate the validity of an event free survival (EFS) endpoint as a surrogate for OS. Methods:OS was measured from randomization for induction therapy to death from any cause (censored at last contact). EFS was measured from randomization to induction treatment failure, relapse after compete response (CR), or death in remission (censored at last contact). Hazard ratios (HR) were computed using Cox proportional hazards models. The association between EFS and OS was evaluated using the Kendall tau-a rank correlation for censored data. Results:There were657 patients enrolled of which 426 patients relapsed or had induction treatment failure before death or date of last contact. Median EFS and OS were 8.0 months (95% CI, 6.3 to 9.7 months) and 23.6 months (95% CI, 16.9 to 23.6 months), respectively. With a median follow-up of 80.1 months, there is a statistically significant correlation between EFS and OS (Kendall tau-a = 0.467, 95% confidence interval (CI) = (0.425, 0.510), p<0.001). This correlation was similarly significant at a median follow-up of 25.2 months (Kendall tau-a = 0.361, 95% CI (0.323, 0.400), p <0.001) when the E1900 trial was originally reported (Fernandez et al. NEJM 2009). Key findings reported based on the original OS endpoint are similar when analyzed with an EFS endpoint (Table 1). High-dose daunorubicin (90 mg/m2) (DNR 90) confers both an EFS and OS benefit in patients aged < 50 years and patients with intermediate cytogenetic risk, and does not confer an EFS or OS benefit in older patients and patients with unfavorable cytogenetic risk, on univariate analysis. Divergent results are only seen in the small subset of favorable cytogenetic risk patients, where DNR 90 conferred an OS benefit (p=0.027) without an EFS benefit (p=0.32). Both EFS and OS endpoints consistently reflect the impact of mutation status on survival. The presence of a FLT3-ITD or DNMT3A mutation has a negative impact on both EFS and OS while an IDH2 mutation has a favorable impact on EFS and OS. The presence of a NPM1 mutation confers a favorable impact on EFS and OS in patients who received DNR 90 and did not impact EFS or OS in patients receiving standard-dose daunorubicin (45 mg/m2) (DNR 45). The presence of an IDH1 mutation does not impact EFS or OS. Conclusions:The results of E1900 demonstrating superiority of DNR 90 in AML induction in patients up to age 60 are concordant when using an EFS or OS endpoint. This is true for the group as a whole as well as for subgroups for which targeted agents are in development (FLT3/IDH2 inhibitors). Further investigation of whether EFS is a reliable surrogate for OS is warranted in AML. If confirmed, its use as a primary endpoint could be adopted by regulatory agencies in order to allow more rapid completion of clinical trials in AML and bring new therapies to AML patients in a timely fashion.

Abstract Background: Patients with high-risk FL intensified with HDT/ASCT may achieve prolonged remissions. The best timing for the procedure remains controversial. Patients who are transplanted in first response show a major Progression Free Survival (PFS) and Event Free Survival (EFS) advantage compared to those treated with conventional chemotherapy. Nevertheless, no randomized studies have yet shown an overall survival (OS) benefit. Populational-based and very long-term retrospective analysis are indispensable tools to assess the actual impact on outcome of therapeutic interventions in FL. With this assumption we performed a retrospective analysis in FL patients undergoing HDT/ASCT intensification included in the GELTAMO Spanish Group Registry. Objectives: The overall outcome as well as the clinical evolution according to the disease status at transplant, to the Follicular Lymphoma International Prognostic Index (FLIPI and FLIPI II) and to the previous exposure to Rituximab. Series characteristics: Six hundred and sixty six patients with FL (mean age 47 years, male 49%) undergoing HDT/ASCT between 1989 and 2007 were reported to the GELTAMO registry. Patients with histological transformation at the time of HDT/ASCT, those undergoing a 2nd transplant and those with a follow-up of less than 7 years were excluded. Thus, 640 patients were included in the analysis. Median follow-up was 12.2 years from HDT/ASCT and 14.2 years from diagnosis. Follow-up from HDT/ASCT was over 16 years for 153 patients (3rd quartile). The median time from diagnosis to HDT/ASCT was 1.8 years. Two hundred and forty-seven patients (38%) never achieved a complete remission (CR) before HDT/ASCT. Two hundred patients (31%) received HDT/ASCT after achievement of first CR (CR1), 43% of them requiring more than one chemotherapy line to achieve CR1; 26% in 2nd CR, 5% in 3rd CR, 21% in 1st partial response (PR), 12% in chemosensitive recurrence, and 5% with active disease. Of the 321 patients assessable for the FLIPI, 33% had a low-risk (LR), 36% an intermediate-risk (IR), and 45% a high-risk (HR) score; and of the 305 patients assessable for the FLIPI II, 22% had a LR, 38% an IR and 40% a HR. Of the 127 patients in CR1 assessable for the FLIPI, 28% had a LR, 40% an IR, and 32% a HR; of the 115 patient assessable for FLIPI II, 14% had a LR, 46% an IR, and 40 % a HR. One third of patients received Rituximab prior to transplant. Results: Median PFS and OS were 9.4 and 21.3 years, respectively. Patients transplanted in CR1 achieved significantly better final PFS (68%) and OS (73%), than those transplanted in 2nd CR (median PFS 110 months (mo.) and final OS 58%; P <.0005) and the latter ones better than those transplanted in 1st PR (PFS median PFS 31 mo. and median OS 118 mo.; P < .0005) (figure 1). Neither FLIPI1 nor FLIPI2 reached statistical significance in patients transplanted in CR1 (P= .5 and P= .2 for PFS and OS, FLIPI 1 comparisons; P= .47 and P= .1 for PFS and OS, FLIPI 2 comparisons, respectively). Although in the global series patients who received Rituximab prior to HDT/ASCT had a better prognosis than those who did not (median PFS not reached vs median PFS 92 mo, respectively, P= .0005; median OS not reached vs median PFS 246 mo, respectively, P= .0012), treatment with Rituximab has no prognostic impact in cases transplanted in CR1. Only 6 patients died beyond 10 years of follow-up, (1 disease progression, 3 second malignancies, 2 unrelated causes). The accumulated incidence of second malignancies of the global series was 12%. A plateau was observed in the PFS and OS curves for patients transplanted in CR1 beyond 15.9 years from transplantation (figure 1). Conclusions: To the best of our knowledge there is no study on the therapeutic impact in the evolution of LF offering such a long follow-up. HDT/ASCT is a good option of consolidation for those patients who achieve a good quality of response with chemotherapy. The finding of a plateau beyond 15.9 years for patients transplanted in first remission suggests that a significant number of patients from this group may never relapse and could be cured, even those with poor initial features.

Abstract INTRODUCTION Patients with high risk medulloblastoma are treated either with high dose chemotherapy or hyperfractionated radiotherapy. Both approaches are not feasible in resource-limited countries. POG9031 trial has reported favourable outcome for high risk medulloblastoma using standard chemotherapy and radiotherapy only. Hence, we have adopted the protocol using chemotherapy first approach due to logistical reasons. OBJECTIVE To review the outcome of children diagnosed with high risk medulloblastoma in Hospital Kuala Lumpur. METHODS Patients diagnosed with high risk medulloblastoma between January 2015 and June 2018 treated using the chemotherapy first approach as per POG9031 protocol were identified. Data was then extracted and analysed. RESULTS Nine patients were identified, 3 boys and 9 girls. Median age was 9.3 years (range 2.6 – 15.9 years). Median follow up for survivors are 3.6 years. Five patients (55.6%) had macroscopic metastatic disease at diagnosis. All patients had significant residual disease post-op. Only 3 patients are disease free till last follow up, giving a 3 years event free survival of 16%. Of the 6 patients who had relapsed, 4 have died, giving a 3 years overall survival of 46%. Patients with no metastasis at diagnosis (M0) fared better with 3 years event free survival of 38%, but 3 years event free survival for patients with macroscopic metastatic disease (M+) was 0%. CONCLUSION Outcome of children with high risk medulloblastoma treated with chemotherapy first approach was dismal.

Abstract Many new therapeutic agents have been approved for follicular lymphoma (FL) but none appear to be curative. Despite novel agents, some patients (pts) experience early relapse, become chemorefractory or suffer transformation into more aggressive lymphomas. Options for these pts are limited. High dose chemotherapy with autologous stem transplant (ASCT) prolongs progression free survival (PFS) and overall survival (OS) in FL pts in first relapse and registry data shows favorable outcome with ASCT in cases of histologic transformation. However, ASCT is usually not curative. Myeloablative allogeneic transplant (MT) has produced long term PFS but is hampered by significant non relapse mortality (NRM) while nonmyeloablative transplant (NMT) has a higher relapse rate compared to MT especially in high risk pts. Finally, many transplant studies have excluded these high risk pts such as those with chemorefractory or transformed disease. We hypothesized that a tandem transplant consisting of an ASCT followed by a NMT would confer the same benefit as a MT without the associated high NRM by separating the high dose chemotherapy from graft versus host disease (GVHD) while preserving the graft versus lymphoma effect. The goal of our study was to improve long term PFS in high risk FL pts. We therefore initiated a prospective protocol in April 2003, for pts with high risk relapsed FL as defined by chemorefractory disease, early 1st relapse, >1st relapse or transformation into aggressive histology. At least one therapy was attempted to document chemosensitivity prior to ASCT. However, regardless of disease status prior to transplant, pts underwent ASCT followed 3 months later by an outpatient NMT from an HLA-identical sibling. NMT comprised 5 days of fludarabine 30 mg/m2/day and cyclophosphamide 300mg/m2/day followed by an infusion of >2x106CD34+ cells/kg. GVHD prophylaxis, chosen to take advantage of the low incidence of acute (a) GVHD and the putative protective effect of chronic (c) GVHD, consisted of tacrolimus starting on day (D) - 8 to achieve levels of 8-12 nmol/L then tapered off by D+100 or D+180 depending on disease risk and of mycophenolate mofetil 1g bid from D+2 to D+50. We previously reported on 27 pts with a follow-up (f/u) of 3 years (yrs). We now report a larger cohort of 40 pts with a median f/u of 8 yrs. Up until July 2015, 40 pts were enrolled with a median age of 50 yrs (34-65). Pts had previously been treated with a median of 3 lines of therapy (2-6). Median time from diagnosis to ASCT was 33 months. Disease status at ASCT was: 14 CR, 16 PR and 10 refractory. Conditioning for ASCT included BEAM/BEAC (n=39), and Cy-TBI (n=1). In addition, 4 pts received radiotherapy after ASCT to sites of previously bulky disease. Median time between ASCT and NMT was 138 days (75-238). Pre NMT disease status was: 25 CR, 12 PR and 3 refractory. Engraftment was prompt in all pts after ASCT and median neutrophil and platelet recovery were respectively 13 days (0-19) and 0 day (0-18) post NMT. Seven pts (18%) developed aGVHD: 2 grade II and 5 grade III. Overall, 29 pts (73%) developed cGVHD: 1 mild, 13 moderate and 15 severe according to NIH revised criteria. Median time to discontinuation of immunosuppression was 22 months. To date, 2 pts have progressed at 11 and 59 months post NMT (one died from relapse and one is now in CR after chemotherapy and DLI) and 5 pts died from either GVHD related complications (n=4) or unknown cause (n=1). All pts alive at last f/u were in CR. With a median f/u of 8 yrs in surviving pts (1-12), OS is 95% at 3 and 5 yrs and 82% at 8 yrs. PFS is 92% at 3yrs, 89% at 5 yrs and 80% at 8 yrs. NRM and relapse rate at 8 yrs are 18% and 6% respectively. Based on our current results in 40 pts, we conclude that ASCT followed by sibling NMT for high risk relapsed FL is associated with excellent disease response and PFS. Furthermore, this tandem strategy appears to be safe and well tolerated. The incidence of cGVHD remains high but could in part explain the impressive PFS in this high risk cohort. This approach should now be further explored in a multi institution setting, include matched unrelated donors and consider the addition of rituximab post-transplant to reduce the incidence and severity of cGVHD with the hope that relapse will not be increased.

9583 Background: Recent studies have shown 5-yr recurrence rates for Stage IIB and IIC melanoma of up to 46%. These high-risk patients currently have few options for adjuvant therapy to prevent this inevitable recurrence, with the only FDA approved therapy being high-dose interferon-alfa, which is quite toxic. However, there are now immunotherapies (anti-PD1) and targeted therapies (anti-BRAF and anti-MEK combinations) which are approved as adjuvants for Stage III patients, some of whom will have a lower baseline recurrence risk than those with Stage IIB/IIC melanoma. We sought to determine if adjuvant PD1 inhibition with nivolumab (N) would improve the recurrence free survival (RFS) compared to historical RFS rates. Methods: Our study (NCT03405155) is a single-arm, open label, multi-center, phase 2 clinical trial evaluating RFS at 24 months in patients with Stage IIB/IIC melanoma on treatment with N at 480 mg IV every 4 weeks for 12 cycles. Overall survival is a secondary endpoint. Associated translational research includes circulating tumor cell DNA and immune correlates. Results: Twenty three patients with Stage IIB and three patients with Stage IIC melanoma were enrolled onto the study and received at least one dose of N. At data cutoff, 22 patients remain in follow up, as four patients withdrew consent at different time points in the study – one patient after one dose who wished to discontinue, one due to concern for COVID and need for repeat visits, one due to insurance issues, and one due to recurrence and wish to discontinue (which was captured in study data and RFS calculations). Seventeen patients have been on the clinical trial for at least two years with nine patients having finished treatment but with less than two years follow-up; the median follow-up is currently 21.9 months. Two patients demonstrated melanoma recurrence, one after receiving cycle six of N and another one year after completing treatment, resulting in a 87.8% RFS (90% CI (64.2%-96.3%) at 2 years, compared to the historical RFS at 2 years of 70%. No N related serious adverse events (SAEs) were observed, with only 2% Grade 3 AEs observed (varied and unrelated to treatment) and all others were Grade 1-2, including 21% GI, 18% cutaneous, and 10% musculoskeletal, respiratory, and fatigue, each; overall, 2% of these Grade 1-2 AEs were treatment related. Conclusions: Our preliminary results show a trend towards improved RFS in patients with Stage IIB/IIC melanoma treated with nivolumab. The cohort has not reached a minimum follow up of at least 2 years for RFS; patients are continuing to be monitored. On study, we observed the expected adverse events, without evidence of new toxicities. Data maturation will reveal the full effect of adjuvant N on disease relapse and overall survival and distant metastasis-free survival in stage IIB/IIC melanoma patients.

Abstract Background. The FL2000 study evaluated the combination of the anti-CD20 monoclonal antibody rituximab with chemotherapy plus interferon in the first line treatment of follicular lymphoma patients. Methods. Untreated follicular lymphoma patients (n=359) presenting with a high tumor burden were randomly assigned to receive either 12 courses of the chemotherapy regimen CHVP (cyclophosphamide, adriamycin, etoposide and prednisolone) plus interferon-α2a (CHVP+I arm) over 18 months or 6 courses of the same chemotherapy regimen combined with 6 infusions of 375 mg/m2 of rituximab and interferon for the same time period (R-CHVP+I arm). The primary endpoint of the study was event free survival and all results are shown as intent to treat. Results. Six months after treatment initiation, 156 out of 183 (85%) and 164 out of 175 (94%) patients had a response to therapy in the CHVP+I and R-CHVP+I study arm, respectively (P=.009). At the end of the 18 months treatment period, 59% and 75% of the patients were respectively in CR or CRu in the CHVP+I and R-CHVP+I arm (P<.05). After a median follow-up of five years, event-free survival (EFS) estimates were respectively 37% [95% C.I. 29 – 44] and 53% [95% C.I. 45 – 60] in the CHVP+I and R-CHVP+I arm (P=.0004). Response duration in CR/CRu or PR patients at the end of the 18 months treatment was also improved in the R-CHVP+I arm (P=.012). 5-year overall survival (OS) estimates were not statistically different in the CHVP+I (79%) [95% C.I. 72 – 84]) and R-CHVP+I (84% [95% C.I. 78 – 84]) arms. The Follicular Lymphoma International Prognostic Index (FLIPI) score allowed separation of the whole study population into 3 different risk categories with significantly different outcome for each group both for 5 year EFS and OS (P<.0001, respectively each). In a multivariate regression analysis, event free survival was significantly influenced by both the FLIPI score (HR=2.08; 95% C.I. [1.6 – 2.8]) and the treatment arm (HR=0.59; 95% C.I. [0.44 – 0.78]). In an exploratory analysis considering the 187 patients with a low/intermediate (<3) FLIPI score, the outcome according to each treatment arm was not statistically different while the benefit of the rituximab combination was highly significant in term of EFS (P=.0002) and OS (P=.025) in the 162 patients with a high (≥3) FLIPI score. Conclusions. These results extend our previous interim analyses and confirm that with a five year follow-up, the combination of rituximab with CHVP+I provides superior disease control in follicular lymphoma patients despite a shorter duration of chemotherapy. However, this combination appears to benefit essentially to high risk patients for whom overall survival is also significantly improved.
