Abstract The IFM99-03 and IFM99-04 trials were conducted from April 2000 to August 2004. Patients younger than 66 years with high-risk (b2microglobulin > 3 and chromosome 13 deletion by FISH analysis at diagnosis) de novo multiple myeloma (MM) were included and prospectively treated. In both protocols, induction regimen consisted of VAD (4 courses) followed by melphalan 200 mg/m2 (HDM200) plus autologous peripheral blood stem cell transplantation (ASCT). When a HLA-sibling donor was available, ASCT was followed by reduced-intensity conditioning regimen (RIC) allograft (fludarabine, antithymocyte globulin and low dose busulfan): IFM9903 protocol (Garban et al, Blood2006;107:3474–3480). When no donor was available, patients were randomised to receive a second ASCT with HDM220 +/− anti-IL6 monoclonal antibody (BE-8, 250 mg total dose, Diaclone Besançon, France): IFM99-04 protocol (Moreau et al, Blood2006;107:397–403).284 patients met eligibility criteria and received at least one course of VAD. 65 had an available HLA-identical sibling donor and were included in the IFM99-03 trial, and 219 were included in the IFM 99-04 trial. Patients were older in the tandem ASCT trial (median age, 58 vs 54 years; P = .006) and the b2-microglobulin level was also higher in the latter group (median, 4.9 mg/L vs 4.1 mg/L; P = .049). At the reference date of July 1st, 2008, on an intent-to-treat basis, considering the entire population of 284 patients, with a median follow-up of 56 months, the EFS did not significantly differ from tandem ASCT to single autograft followed by allo-RIC (median 22 vs 19 months, P = 0.58). Nevertheless, there was a trend for a superior OS in the double ASCT trial (median 48 vs 34 months, P = 0.07). When considering the comparison of the results of the 166 patients /219 who completed the whole tandem ASCT protocol with those of the 46 patients /65 who underwent the entire auto/allo-RIC program, no difference was observed regarding EFS (median 25 vs 21 months, P = 0.88), but there was again a trend for a superior OS in favour of double ASCT (median OS, 57 vs 41 months, P = 0.08), due to a longer survival after relapse in the tandem ASCT arm. These long-term results indicate that, in a subgroup of high-risk patients with de novo MM, a tandem autologous transplant procedure is at least equivalent or even superior to a combination of autologous followed by RIC allogeneic stem cell transplantation.

Prospective Comparison

The Intergroupe Francophone du Myélome (IFM) initiated 2 trials in 1999 to study patients with high-risk (β2-microglobulin level greater than 3 mg/L and chromosome 13 deletion at diagnosis) de novo multiple myeloma. In both protocols, the induction regimen consisted of vincristine, doxorubicin, and dexamethasone (VAD) followed by first autologous stem cell transplantation (ASCT) prepared by melphalan 200 mg/m2. Patients with an HLA-identical sibling donor were subsequently treated with dose-reduced allogeneic stem cell transplantation (IFM99-03 trial), and patients without an HLA-identical sibling donor were randomly assigned to undergo second ASCT prepared by melphalan 220 mg/m2 and 160 mg dexamethasone with or without anti–IL-6 monoclonal antibody (IFM99-04 protocol). Two hundred eighty-four patients—65 in the IFM99-03 trial and 219 in the IFM99-04 trial—were prospectively treated and received at least one course of VAD. On an intent-to-treat basis, overall survival (OS) and event-free survival (EFS) did not differ significantly in the studies (medians 35 and 25 months in the IFM99-03 trial vs 41 and 30 months in the IFM99-04 trial, respectively). With a median follow-up time of 24 months, the EFS of the 166 patients randomly assigned in the tandem ASCT protocol was similar to the EFS of the 46 patients who underwent the entire IFM99-03 program (median, 35 vs 31.7 months), with a trend for a better OS in patients treated with tandem ASCT (median, 47.2 vs 35 months; P = .07). In patients with high-risk de novo MM, the combination of ASCT followed by dose-reduced allogeneic transplantation was not superior to tandem dose–intensified, melphalan-based ASCT.

Abstract Abstract 247 Background: The presence of minimal residual disease (MRD) after allogeneic stem cell transplantation (SCT) for Ph+ ALL is highly predictive of eventual relapse. Imatinib (IM) has very limited efficacy in hematologic relapse of Ph+ALL, but may prevent leukemia recurrence if started when the leukemia burden is still very low and detectable only by molecular techniques. The optimal time for starting IM post transplant and the prognostic relevance of different bcr-abl transcript levels in relation to time after SCT have not been established. Aims: To determine the impact of post-transplant IM, given either prophylactically or after detection of bcr-abl transcripts (pre-emptively), on the overall incidence of MRD, remission duration, long-term treatment outcome and tolerability in pts. who underwent SCT for Ph+ALL in complete remission. Study Design: In a prospective, randomized multicenter trial, previously transplanted Ph+ ALL pts. (n=55) were assigned to receive imatinib prophylactically (n=26) or pre-emptively (n=29). SCT was performed in CR1 in 23 pts. and 27 pts. in the two groups, respectively. Five pts.were transplanted in CR2. Serial assessment of bcr-abl transcripts was performed by quantitative RT-PCR and additionally by nested-RT-PCR if the sensitivity of the qRT-PCR was below the quantitative range. Confirmatory testing of a second independent sample was not required, to reduce the risk of treatment delays. Samples were considered PCR negative only if the ABL copy number exceeded 104. Imatinib administration was scheduled for one year of continuous PCR negativity. Results: IM was started in 24/26 pts. allocated to prophylactic IM and in 14/29 pts. in the pre-emptive arm. The majority of pts. received IM 400 mg/d (26/38 pts.), the other 12 pts. 600 mg IM daily. IM was started a median of 48 d after SCT in the prophylactic arm and 70 d after SCT with pre-emptive therapy. After a median follow-up of 30 mos. and 32 mos., respectively, 82% and 78% of pts. are alive in ongoing CR, 4 pts. died in CR. Five pts. transplanted in CR1 and 2/5 pts. transplanted in CR2 have relapsed (median follow-up 9 mos. and 10.5 mos., respectively). The frequency of MRD positivity was significantly lower in pts. assigned to prophylactic imatinib (10/26; 40%) than those in the pre-emptive treatment arm (20/29; 69%) (p=0.046 by chi2 test). Only 9 of 29 pts. assigned to pre-emptive imatinib remained continuously PCR negative after SCT, with a median follow-up of 32 months (18–46 months) after SCT. The median duration of sustained, uninterrupted PCR negativity after SCT is 26.5 months with prophylactic and 6.8 months with pre-emptive administration of imatinib (p=0.065). The probability of remaing in CHR after SCT was significantly lower in partients who remained MRD negative after SCT (p=0.0002). Analysis of the kinetics of molecular relapse showed that detection of bcr-abl transcripts within 100 days of transplant, despite rapid initiation of IM, was associated with a significantly inferior EFS compared to first detection of MRD positivity more than 100 days after SCT. IM was discontinued prematurely in 54% pts. receiving imatinib prophylactically and in 64% of pts. receiving imatinib pre-emptively, mostly due to gastrointestinal toxicity. Accordingly, the time to IM discontinuation was 245 d and 191 d in the prophylactic and the pre-emptive treatment arms, respectively. Despite this early discontinuation rate, overall survival in the two treatment groups was 80% and 74.5% after 5 years, with no significant difference by log rank test (p=0.84). Conclusions: Prophylactic administration of imatinib significantly reduces the incidence of molecular relapse after SCT. Both interventional strategies are associated with a low rate of hematologic relapse, durable remissions and excellent long-term outcome in patients with Ph+ ALL. The presence of MRD both prior to and early after SCT identifies a small subset of patients with a poor prognosis despite post-transplant imatinib, and warrants testing of alternative approaches to prevent hematologic relapse.

10054 Background: Current treatment strategies including high-dose chemotherapy with stem cell transplantation rescue (HDC-SCT) have improved 5-year event-free survival for high-risk neuroblastoma (HRNB) patients, but with an increased risk of late treatment-related toxicities. Methods: Between 1980 and 2012, 439 children were treated for HRNB with HDC-SCT in Gustave Roussy (GR), among which 145 were alive and disease-free at 5-year post-SCT. Long-term health data have been collected for those 145 patients, prospectively within the long-term follow-up clinic in GR or retrospectively from pediatric consultations. Results: With a median follow-up post-SCT of 15 years (range 5-34), we observed 6 late relapses, 11 second cancers (including 3 papillary thyroid carcinomas; median delay = 20 years post-SCT [18-22]) and 9 deaths. Event-free and overall survival at 20-year post-SCT were 82% (95%CI = 70–90) and 89% (95%CI = 78–95), respectively. A second health event was observed in 135 patients (median = 3/patient), including 103 patients with at least 1 severe event (median = 1/patient). Cumulative incidence at 15-year post-SCT for second cancers is 4%, cardiac diseases 8%, thyroid 11%, renal 7%, hepatic focal nodular hyperplasia 14%, dental mal-development 70%, and severe hearing loss 20%. Height-for-age z-score was ≤-2 for 30 patients (21%) and ≤-3 for 12 patients (8%). After Busulfan-Melphalan conditioning regimen, 40/43 females and 33/35 males had a gonadal insufficiency. Conclusions: Long-term consequences of HRNB treatment including HDC are frequent and disabling, mainly due to hearing loss and gonadal insufficiency.

The development of new inhibitory and immunological agents and combination therapies significantly improved response rates and survival of patients diagnosed with multiple myeloma (MM) in the last decade, but the disease is still considered to be incurable by current standards and the prognosis is dismal especially in high-risk groups and in relapsed and/or refractory patients. Allogeneic hematopoietic stem cell transplantation (allo-SCT) may enable long-term survival and even cure for individual patients via an immune-mediated graft-versus-myeloma (GvM) effect, but remains controversial due to relevant transplant-related risks, particularly immunosuppression and graft-versus-host disease, and a substantial non-relapse mortality. The decreased risk of disease progression may outweigh this treatment-related toxicity for young, fit patients in high-risk constellations with otherwise often poor long-term prognosis. Here, allo-SCT should be considered within clinical trials in first-line as part of a tandem approach to separate myeloablation achieved by high-dose chemotherapy with autologous SCT, and following allo-SCT with a reduced-intensity conditioning to minimize treatment-related organ toxicities but allow GvM effect. Our review aims to better define the role of allo-SCT in myeloma treatment particularly in the context of new immunomodulatory approaches.

Long Term Follow Up

Abstract Abstract 1811 Poster Board I-837 The prognostic significance of achieving complete remission (CR) in Multiple Myeloma (MM) has finally been accepted. However, available studies have been based on series with a median follow-up around 5 years. This time period is insufficient according to the current life expectation of MM. Aim To establish the real effect of prognosis of the different response categories in a cohort of MM patients treated with autologous stem cell transplantation (ASCT) after long term follow up. Patients and methods Follow-up from diagnosis of 344 MM patients transplanted between 1989 and 1998 has been updated. These patients were previously included in a study aimed at establishing the post-ASCT response significance in MM and to validate the EBMT classification (Br J Haemat 2000;109:438-46). It was possible to update the follow up of 322 patients as at April 2009. At this date 99 patients were alive with a median follow-up form diagnosis of 12.5 years. Response categories and evaluated cases were: i) Complete Response (IF-) (CR), n= 84 ii) near Complete Response (EF-/IF+) (nCR), n= 66 iii) Very good partial response (VGPR) (<90% reduction of M component), n= 66 iv) Partial response PR (reduction of M component between 90-50%), n= 113 v) Stable Disease (SD), n= 12, y vi) Progression (PD), n=14 Survival analyses were performed by Kaplan-Meier curves (log-rank test). Cox logistic regression was employed to establish variables associated with a higher survival. Results Significant differences in overall survival (OS) and event free survival (EFS) were found between CR and nCR groups (p 0.01 and 0.0022, respectively); or between CR and VGPR (p 0.0001 and 0.0035); no differences were detected between nRC and VGPR groups (p 0.21 and 0.99) and between these groups and PR group (p 0.1 y p 0.8). OS and EFS of patients with ED o PD were lower than the rest of the groups. Overall survival at 12 years was 43% in CR patients, 21% in nCR, 20% in VGPR, 30% in PR, 8% in SD and 0% in PD groups. Median survival (OS, EFS respectively) of each group was 91 months and 36 m, 26 m and 21 m, 20 m and 15 m, 31 m and 12 m, 8 m and 5 m, and 6 and 1 month. Land-mark study (10 years) found a plateau phase in OS and EFS after 11 years. Twenty two percent of patients are still alive with stable status between 11 and 15.54 years and only two cases had relapsed in the non CR group. In a regression study for OS, response was only one variable with statistical significance (CR P <0.0000, OR 0.044, IC-95%: 0.020-0.30). Conclusions In MM achieving CR after ASCT is the most important prognostic factor even after long-term follow-up. Relapse rate is very low in patients with >11 years of follow-up, this could mean a cure for patients in CR. Disclosures No relevant conflicts of interest to declare.
