Abstract Objectives We report a new case of immunoglobulin E multiple myeloma (IgE), a very rare isotype that accounts for <0.1% of cases of this monoclonal gammopathy. To ensure the adequate detection, quantification and identification of the monoclonal component, it is crucial that protein assays are performed. We provide some clues related to clinical laboratory results, which will facilitate an adequate management of the disease. Case presentation A 45-year-old patient with a five-week history of pain at the level of the elbow, who was diagnosed with IgE-Kappa multiple myeloma based on laboratory, radiological, and bone marrow findings. The patient received induction chemotherapy prior to hematopoietic stem-cell transplantation and is currently on follow-up. Conclusions Protein assays performed in the clinical laboratory, including protein electrophoresis and immunofixation, allowed for the detection of an IgE-Kappa monoclonal component prior to the appearance of the typical CRAB symptoms (hypercalcemia, renal involvement, anemia, and bone pain) of multiple myeloma (MM). The detection of IgE-Kappa facilitated early diagnosis and management.

Background: Fanconi anemia (FA) is the most frequent genetic cause of bone marrow failure (BMF) due to a DNA repair mechanism defect. The natural history of FA is marked by progressive BMF during early childhood. Throughout life, the hematopoietic situation may change by clonal evolution toward myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML). Hematopoietic stem cell transplantation (HSCT) is the only curative treatment for bone marrow failure in FA patients. The role of HSCT for FA patients with AML or advanced MDS is less defined. Currently, HSCT first line result offers 50% Overall Survival (OS) for patients with cytogenetic abnormalities only and 30% OS for patients with advanced MDS or AML in FA (Ayas et al., JCO 2013; Mitchell et al., BJH 2014). We previously reported a FLAG-sequential approach in 6 patients with FA (5 AML and 1 advanced MDS), all alive at a median follow-up of 28 months (Talbot et al., Hematologica 2014). We update here those patients and report 12 more patients treated by FLAG-sequential since then. Materials & Methods: This retrospective study (2006-2019) was conducted in 7 centers in France and Brazil on behalf of the French Reference Center for Aplastic Anemia to evaluate FLAG-sequential in FA patients with morphological clonal evolution (no patients with cytogenetic abnormalities only). The study was conducted in accordance with the Declaration of Helsinki. Anonymous data collection was declared to the appropriate authorities. The FLAG-sequential treatment consisted of FLAG, Fludarabine 30 mg/m²/d for five days and Cytarabine 1 g/m²x2/d with G-CSF for five days, which was followed three weeks later by Cyclophosphamide 10 mg/kg/d for four days, Fludarabine 30 mg/m²/d for four days and TBI 2 Gy (Fig 1A). In a haploidentical setting, Cyclophosphamide at 30 mg/kg/d was performed only in post-transplantation, at Days +4 and +5 (Fig 1B). Results: Eighteen patients were included with 14 AML, 1 acute lymphoblastic leukemia (ALL), and 3 RAEB-2 (Table 1). The median age at the time of HSCT was 22 years (4-37 years). Fifteen patients (83%) were older than 10 years at the time of HSCT. The median follow-up was 31 months (3- 153 months). Eight patients (44%) had complex karyotype. None of the included patients had a history of solid malignancies before HSCT. All patients engrafted. The cumulative incidence of neutrophil engraftment at Day 60 was 94% (95% CI 63-100%) with a median of 18 days (12-343 days). The cumulative incidence of platelet engraftment at Day 60 was 83% (95% CI 50%-96%) with a median of 25 days (17-245 days). The donor chimerism was complete at Day +100 for 15 patients. The three patients without full donor chimerism at Day +100 either had a relapse (n=1) and 2 early deaths before Day+100 from steroid-refractory aGVHD (n=1) or septic shock (n=1). None of the patients received a second HSCT. Non-relapse mortality (NRM) at 3 years was 32% (95% CI 6-58%) (Fig 2). Cumulative incidence of grades II to IV aGVHD was 56% (35% grades III to IV). Cumulative incidence of extensive cGVHD was 16%. Infectious complications during HSCT include the following: CMV (n=8), EBV (n=2), adenovirus (n=4), BK virus (n=7), respiratory syncytial virus (n=1), candidaemias (n=2) and invasive aspergillosis (n=3). Progression free survival (PFS) and OS at 3 years were 53% (95%CI 32-89%) and 53% (95%CI 32-89%), respectively (Fig 2). Cumulative incidence of relapse at 3 years was 13% (95%CI 0-31%) (Fig 2). Seven patients died during the study. Causes of death were relapse (n=2), aGVHD (n=2), cGVHD (n=1), septic shock (n=1), and respiratory syncytial virus associated with invasive aspergillosis (n=1). GVHD-relapse free survival (GRFS) at 3 years was 48% (95%CI 29-78%). One patient had anal epidermoid carcinoma at 4 years after HSCT, which required multiple surgical ablations. Conclusion: With almost 3 years follow-up, which is long enough for our results to be considered robust, we report an OS and PFS of 53%, which compares favorably to historical controls since all of our 18 patients were treated with florid disease at time of HSCT (and not with cytogenetic abnormality only, known to be associated with a better prognosis). Toxicity is still a concern in this particular population of FA patients with notably a high rate of infectious complications. Future well designed prospective clinical trials will refine this sequential strategy, which appears promising in this particular difficult clinical situation.

Sinonasal Polyposis

Woakes’ syndrome is a rare entity defined as recurrent sinonasal polyposis with a consequent nasal pyramid deformity. Only a few cases are reported in the literature. The goal of this study is to present the features of Woakes’ syndrome through a clinical case. A 42-year-old man presented with a history of ASA triad. He started self-medication for 5 years. He returned to the otorhinolaryngology department for the aggravation and persistence of symptoms. CT scans showed the deformity and thinning of the nasal bones. A functional endoscopic sinus surgery and correction of nasal pyramid deformity were performed. At 6 months' follow-up, good functional and aesthetic outcomes were observed. Woakes’ syndrome was described more than 130 years ago. Treatment includes endoscopic sinonasal surgery and local treatment. Adequate management and good adherence to the therapeutic protocol could be factors to prevent this syndrome.

Abstract Abstract 1227 Poster Board I-249 Background In comparison with single autologous hematopoietic stem cell transplantation (auto HCT), tandem autologous HCT has resulted in longer event-free and overall survival in randomized trials for patients with newly diagnosed multiple myeloma (MM). Most myeloma patients, however, only receive a single auto HCT. Many of these patients are eligible for a second auto HCT as salvage at the time of relapse. We evaluated the outcome of salvage auto HCT for MM patients treated at our institution. Methods We performed a retrospective chart review and identified 62 MM patients (38 males, 24 females) who received a second auto HCT as salvage between 1/3/1992 and 11/4/2008.. Preparative regimen was high-dose melphalan alone or in combination with other chemotherapy agents, including busulfan, topotecan and bortezomib. Three patients received a combination of thiotepa, busulfan and cyclophosphamide. Results Median interval between the first and salvage auto HCT was 21 months (range 2-81). Median age at salvage HCT was 55 years (37-73) and median prior treatment regimens were 4 (range 2-16). Twelve patients had chromosomal abnormalities on conventional cytogenetic studies. Patients received a median CD34 cell dose of 4 ×106 / kg (range 2.3-11.2). Fourteen patients (22%) experienced grade 3 or higher toxicity after the salvage auto HCT. Two patients died within 100 days with a TRM of 3%. Median time to neutrophil engraftment was 10 days (8-38). Responses after salvage auto HCT were as follows: CR+ near CR 15%, PR 48%, with an overall response rate of 63%. Twenty-seven (44%) patients received post auto HCT maintenance therapy. Median follow-up from salvage HCT was 25 months. Kaplan-Meier estimates of median progression-free survival and overall survival (OS) were 15.5 and 43.3 months, respectively. Median time to progression after the first and salvage auto HCT was 20 and 12 months, respectively, with total remission duration of 32 months from two HCTs. Median OS from the time of diagnosis was 72 months, comparable to reported results with tandem auto HCT. At last follow up, 20 patients were alive and in remission. Conclusions In selected MM patients a second auto HCT for salvage therapy is well tolerated with acceptable toxicity. The combined remission duration and overall survival are comparable to outcomes with tandem autotransplants. Disclosures Qazilbash: Cephalon: Speakers Bureau.

Abstract Abstract 4124 BACKGROUND: Most patients (pts) undergoing high-dose therapy with melphalan 200 mg/m2 (HDM) and autologous transplant for multiple myeloma (MM) develop disease recurrence. The optimal salvage treatment including autologous (auto-) and allogeneic (allo-) hematopoietic stem cell transplantation (SCT) as consolidation therapy for these patients is not yet defined. METHODS: We performed a retrospective analysis of 116 pts with MM treated in our institution between 1999 and 2005. Inclusion criteria were relapse after auto-SCT (n=88) or failure of induction treatment (n=28) and age ≤ 65 years. Re-induction was performed with TCED (thalidomide, cyclophosphamide, etoposide and dexamethasone (Möhler et al, Blood 2001). Seventy-one pts (median age, 59 yrs) received auto-SCT (auto-group) after HDM followed by maintenance therapy with thalidomide or interferon-alpha in 42 pts. Forty-five pts (allo-group, median age, 53 yrs) underwent a reduced-intensity allo-SCT (related in 24 pts), mostly using conditioning with 2 Gy total body irradiation and fludarabine. Thirty-eight pts received an auto-allo-tandem-SCT (Maloney, Blood 2003) and 7 pts have been directly transplanted after TCED. Statistical analysis was done using the two-stage test of Qiu & Sheng (JRSS Ser. B 2008) to compare two possibly crossing survival curves. Extended Cox proportional hazards regression models were applied to allow for time-varying differences between the two SCT groups. RESULTS: Estimated median follow-up after start of TCED was 95 months. All pts received a median number of 3 TCED cycles for re-induction therapy. 64 of 116 pts (55%) showed at least a PR after TCED chemotherapy (CR in 3 pts). TRM was 17% after 2 years in the allo-group and differed significantly from the auto-group (3%, p=0.02). More CR were achieved after allo-SCT compared to auto-SCT (17 vs. 4 pts., p<0.001). Median overall survival (OS) was 26 months for the auto group and 23 months for the allo group (Figure 1, p=0.16). Median progression-free survival (PFS) was 12 months for both groups but crossing hazards were observed (Figure 2, p=0.03, two-stage test of Qiu & Sheng). The results of multivariate regression analysis for OS and PFS including age at relapse-SCT, response to TCED, time between first diagnosis until first relapse-SCT and primary progression are shown in table 1. In the allo group, there was no OS or PFS difference between related and unrelated donors (multivariate analysis). Cumulative incidence of chronic GvHD was 73% (53% extensive). Patients with chronic GvHD showed a better OS and PFS than pts without (univariate analysis, both p<0.01). CONCLUSIONS: To our knowledge, this is the first analysis in a large number of patients with a long follow-up comparing allo with auto SCT in 1st myeloma relapse which were treated uniformly with TCED therapy for re-induction. Main problem was MM recurrence. However, younger pts with disease response after TCED and longer time from first diagnosis to first SCT after relapse profit best from TCED and this transplant approach. Most interestingly, disease control is better after allo compared to auto SCT in univariate and multivariate analysis leading to a PFS of about 20% after 4 years. In our opinion, allo SCT is a valuable clinical option for patients with 1st relapse after HDM and auto SCT. Disclosures: No relevant conflicts of interest to declare.

Abstract Introduction The prognosis of patients with multiple myeloma (MM) has improved in the last years due to the important advances in the knowledge of the biology of the disease, the implementation of new drugs and the incorporation of autologous hematopoietic stem cell transplant (autoHSCT). The allogenic hematopoietic stem cell transplant (alloHSCT) continues to be controversial: it offers a curative potential but with the cost of high toxicity, limiting the procedure to those young patients with a high-risk disease. This procedure shall be performed in expert centers and, whenever possible, in the context of a clinical trial. In the following we describe the experience of our center with alloHSCT in advance multiple myeloma patients. Patients and methods A total of 18 patients were diagnosed with multiple myeloma received an alloHSCT during a 13 year period (1996-2013), with a median age of 46 ± 5.9 years. All of our patients received an allogenic HLA matched sibling donor with reduced-intensity conditioning. The majority of patients were transplanted because of advanced disease, relapse after an autologous transplant or as part of a sequential transplant in patient with a high risk disease. One patient received, in two occasions, an alloHSCT. Around 70% of patients had received more than 3 previous lines of treatment including, in nearly 95%, an autoHSCT. Patient's characteristics can be found on table 1, characteristics of the procedure can be found in table 2.Table 1.Patient«s CharacteristicsN (%)GenderMale Female10 (55,5%) 9 (44,4%)Secreted ProteinIgGκ IgG λ IgA κ BJ Plasmocitoma8 (44,4%) 4 (22,2%) 2 (11,1%) 3 (16,7%) 1 (5,6%)Debut DS stageII-A II-B III-A III-B Plasmocitoma5 (27,8%) 1 (5,6%) 8 (44,4%) 3 (16,7%) 1 (5,6%)Cytogentics at diagnosisMissing Unfavorable Favorable10 (55,5%) 6 (33,3%) 2 (11,1%)Previous lines of treatment²2 3-4 ³56 (33,3%) 10 (55,5%) 2 (11,1%)Previous autoHSCTYes No17 (94,5%) 1 (5,6%)Previous radiotherapyYes No8 (44,4%) 10 (55,6%)Disease status at transplantComplete remission Partial remission Relapse9 (50,0%) 3 (16,7%) 6 (33,3%)Table 2.Treatment characteristicsN (%)Conditioning regimenMyeloablative Reduced-intensity6 (33,3%) 12 (66.7%)Stem cell sourceBone marrow Peripheral blood4 (22.2%) 14 (77.8%)GVHD prophylaxisCsA+MTXCsA+CSCsA+MMF10 (55.6%) 3 (16.7%) 5 (27.8%)InfectionsYes No16 (88.9%) 2 (11.1%)MucositisYes No12 (66.7%) 6 (33.3%)Acute GVHDYes II-IV III-IV No4 (22.3%) 3 (16.7%) 1 (5.6%) 14 (77.8%)Chronic GVHDNo Limited Extensive8 (44.3%) 5 (27.8%) 5 (27.8%) Results: Transplant related mortality (TRM) before day 100th was one case due to a thromboembolic event. Global TRM was 16.6% (3 cases). The incidence of acute graft versus host disease (aGVHD) was 22%, controlled on most cases when corticosteroids were initiated. More than half of the patients developed chronic graft versus host disease (cGVHD), with an equal distribution on either presentation as limited or extensive. (Table 2) The total number of patients eligible for analysis was 17 (one patient was lost on follow-up). With a median follow up of 11 years, the overall survival (OS) was of 8.06 years [IC 95% 4,33-11,78] (figure 1.) and the estimated progression free survival (PFS) was of 25.83 months [IC 95% 8.87-42.79](figure 2). A total of 5 (29,4%) patients are still alive and 2 (11,7%) of them are in complete remission, of these 1 patient did not have a previous autoHSCT with a follow up of almost 15 years. Conclusions: Our results are similar to those reflected on the literature1-2. However we have to point out that our population is homogenous with advanced MM with more than 3 previous lines of treatment including in most cases auto-HSCT. In spite of this, morbility and mortality in our cohort was acceptable with the limitation of a high rate of cGVHD. There is a need of more studies including more patients to evaluate the role of alloHSCT in the era of new drugs for MM. References 1. Rosi-ol L et al.

Abstract Objective: To evaluate the efficacy and long-term outcome of the total treatment of induction therapy, ASCT and consolidation and maintenance therapy. Methods: A retrospective analysis was made on in multiple myeloma patients in our center between April 1, 2003 and February 1, 2016. The 157 patietns received autologous hematopoietic stem cell transplantation and review the autologous transplantation of long-term follow-up results. Analysis of the effect of transplantation efficacy, the impact on survival remission of different transplantation depth, transplantation in first line or not, salvage transplantation, prognosis of different staging system and other factors. Results: The baseline characteristics of the patients were shown in table 1. Overall patient ASCT before total effective rate (ORR) was 93.6%, in which the complete remission (CR) ratio was 33.1%. After ASCT, the best treatment response rate of PR was 80.3%, and the rate of CR was 58.6%. 91.69 months of median follow-up, patients with an overall survival (OS) and progression free survival (PFS) respectively 91.69 and 50.76 months; in 2005 before the median OS and PFS 39.0m and 23.0m. In 2005 after respectively and 56.41m 120.90m, P = 0.000. The median OS and PFS in the first line transplantation group and salvage transplantation group were vs 54.21m 39.0m and vs 7.09m 119.0m (P value was 0). 136 cases of patients with R-ISS stage, I, II, III of the patients with the median survival time were 120.90m (n=46), 86.43m (n=69), 35.65m (n=21), there were significant differences between groups, p=0.000. Each period of PFS were 72.11m, 51.84m, 28.09m, I and II, III,, p=0.001 and p=0.03, while there was no significant difference between II and III, p=0.122. The received autologous transplantation as first-line and salvage treatment of patients with subgroup survival analysis, median OS of the R-ISS stage III patients and different 15.84m 35.65m, P = 0.031; two groups of patients the median PFS (phase I: 91.69m vs18.92m; II: vs 16.69m 53.42m; phase III: vs 5.91m 28.52m) have difference (P = 0.000). In the first-line transplantation group, transplantation is more than or equal to PR and did not get effective PR group between OS were significantly different; before transplantation achieved CR, PR but did not obtain Cr and did not get effective PR group between PFS were significantly different; after transplantation and achieved CR CR did not get the patients had a median PFS were 65.57m 48.13m, P = 0.039 and median OS no difference. Accept any kind of noval agent- based chemotherapy were significantly longer OS and PFS than traditional chemotherapy (P = 0.001, P = 0.004) .There was no obvious difference on median OS between based regimen (bortezomib group median OS: NR; thalidomide group:120.90m); PFS in thalidomide group (median PFS : NR vs 54.21m) significantly prolonged (P = 0.010). By comparing the baseline characteristics of the two groups, it was found that the PFS was significantly shorter in the bortezomib group with an extra medullary lesion. Multivariate analysis showed that only R-ISS and the depth of remission before transplantation had effect on OS (p=0.003) and PFS (p=0.036) respectively. Conclusion: The total treatment of novel agent-based chemotherapy and ASCT for transplantation-eligible multiple myeloma patients is effective, further improve the remission rate and remission depth, prolong PFS and OS, the overall median survival up to 120.9m. First line transplantation can significantly prolong the OS and PFS compared with salvage transplantation. R-ISS and pre-transplant remission depth are prognostic factors influencing survival of patients. The total treatment to thalidomide based without extramedullary perhaps makes patients get long-term survival. Disclosures No relevant conflicts of interest to declare.

Background: In multiple myeloma (MM), relapse is a problem after autologous hematopoietic stem cell transplantation (ASCT). In the nontransplant setting, thalidomide/dexamethasone/clarithromycin (BLT-D) and lenalidomide/dexamethasone/clarithromycin (BiRd) achieve responses with acceptable toxicity. Both regimens are reasonable objects of study in the post-ASCT setting. Patients and Methods: We report on BLT-D and BiRd given post-ASCT. Studies were conducted consecutively. After recovery from ASCT, therapy was started. All 3 drugs were given for 1 year, and then immunomodulatory drugs alone were given as long as tolerated or until disease progression. Results: For BLT-D, the most common toxicity was peripheral neuropathy (PN). For BiRd, infection, PN, and neutropenia were the most common adverse events. BiRd was associated with a higher frequency of secondary cancers. The median follow-up for BLT-D was 10.2 years (range 8.6-10.7) and for BiRd it was 7.5 years (range 6.4-8.4). After BLT-D, 18 patients (67%) were alive and 10 (37%) were alive without disease progression, and after BiRd, 18 patients (58%) were alive and 10 (32%) were alive without disease progression. Conclusions: BLT-D and BiRd can be given post-ASCT with different toxicity profiles and comparable disease-free and overall survival rates. A randomized study comparing these regimens to single-agent lenalidomide is needed to determine which approach is superior. Key Message: Relapse of MM is a major problem after ASCT. Strategies are needed post-ASCT to improve outcomes. In the nontransplant setting, thalidomide or lenalidomide/dexamethasone/clarithromycin treat MM with acceptable toxicity. We, thus, studied both regimens post- ASCT. They can be given with different toxicity profiles and result in good disease control.

Abstract Background . Renal involvement is a common complication of multiple myeloma (MM). However, most studies have focused on renal failure in MM, and little information is available about the other renal manifestations in MM and their association with immunophenotypes and renal pathology. Methods . We retrospectively analyzed the clinical, laboratory and pathology data of 283 MM patients treated in Sichuan Provincial People’s Hospital, West China, between January 1990 and May 2017. The patients were divided into a renal involvement group (n = 200) and a non-renal involvement group (n = 83). Results. In the renal involvement group, 90 (45.0%) patients were diagnosed with MM in the Nephrology department, and isolated proteinuria, renal failure and nephrotic syndrome were detected in 90(45.0%), 94 (47.0%) and 58 (29.0%) patients, respectively. 135 patients with renal involvement underwent immunofixation electrophoresis, and IgG, IgA, IgD, IgE, pure light chain and nonsecretory MM were detected in 52 (38.5%), 32 (23.7%), 1 (0.7%), 1 (0.7%), 45(33.3%) and 4 (3.0%) patients, respectively. 47 patients without renal involvement also underwent immunofixation electrophoresis, and IgG and IgA MM were found in 24 (51.0%) and 18 (38.3%) patients, respectively. Severe anemia and hypertension, hypercalcemia and pure light chain were more frequent in patients with renal involvement (P < 0.05).9 patients with renal involvement were performed renal biopsy, and cast nephropathy, renal amyloidosis were proved in 5 and 4 patients, respectively. Conclusions. Renal involvement was common at MM diagnosis and had diverse clinical manifestations. The most common clinical manifestations include renal failure, isolated albuminuria and nephrotic syndrome. Nephrologists should rule out MM in patients presenting with renal involvement.
