Abstract: Introduction. The fludarabine, cyclophosphamide, rituximab (FCR) regimen is associated with high complete response (CR) rates and a negative residual disease status in a significant proportion of cases and is considered the optimal front-line treatment for fit patients with chronic lymphocytic leukemia (CLL). In addition, long-term follow-up of patients treated with FCR at the MD Anderson Cancer Center, in the multicenter German CLL8 study and at Italian institutions indicate that a sizable fraction of patients characterized by a favorable biologic profile remains free from progression in excess of 10 years. FC combined with ofatumumab (FC-O), a human monoclonal antibody which targets an epitope of the CD20 molecule, has also been associated with a high CR rate. The aim of this study was to evaluate whether a double dose of ofatumumab (O2) combined with FC could improve the CR rate in young (≤65 yrs) and fit patients with CLL. Methods. Sixty-one fit CLL patients from 15 Italian institutions were enrolled in this front-line study and treated with the FC-O2 regimen based on the FC schedule (F 25 mg/sqm i.v. d1-3, C 250 mg/sqm i.v. d1-3) combined with 13 doses of O (300 mg i.v. d14; 1000 mg d21 at the first cycle; 1000 mg d1 and d15 at cycles 2-6 and d28 at cycle 6). As infection prophylaxis, patients received bactrim and peg-filgrastim in order to prevent granulocytopenia. CLL diagnosis, treatment requirement and response were assessed according to the 2008 iwCLL guidelines. Minimal residual disease (MRD) was evaluated by flow cytometry in the peripheral blood (PB) and bone marrow (BM), and also by RQ-PCR in flow negative cases. CT scan evaluation was included in the response assessment. Adverse events (AEs) were graded according to the NCI-CTCAE. Results. The median age of patients was 60 years (range 36-65), Binet stages B and C were recorded in 86% of cases, B-symptoms in 21%, increased β2M values in 74% and bulky nodes (≥5 cm) in 10%. An IGVH unmutated status was recorded in 60% of cases, deletion 13q in 37%, no aberrations in 33%, deletion 11q in 14%, trisomy 12 in 12%, 17p deletion and/or TP53 mutation were found in 10% of cases. At present, the median follow-up of patients is 7 months (range 1-20). Response to treatment has been assessed in 29 patients after a median number of 6 courses of treatment (range 2-6). The overall response rate is 90%, with a CR rate of 69% (20 patients). No evidence of MRD was observed by flow cytometry in both PB and BM in 15/20 CR patients (75%). To date, 11 patients with cytometric MRD negative CR have been evaluated by RQ-PCR and no residual disease was detected in 3. Grade 3-4 granulocytopenia was recorded in 4 patients (7%), a severe infection in 4 (7%) and 5 patients (8%) experienced a severe infusion-related reaction during ofatumumab administration. Treatment was discontinued in 8 patients as a result of toxicity (infection, 2 cases; FUO, 1; infusion-related toxicity, 1; autoimmune hemolytic anemia, 1; recurrent granulocytopenia, 1; tachyarrhythmia, 1; non-specified toxicity,1). A non-treatment-related death (traumatic aortic transaction due to a dislocated aortic endoprostheses) has been recorded in a patient after 2 months from treatment discontinuation and 1 showed a disease progression after 4 courses of FC-O2. Conclusions. Taken together, the first analysis of this ongoing front-line study suggests that the combination of FC with an increased dose of ofatumumab is well tolerated with acceptable and no unexpected toxicity. Our preliminary results show that the FC-O2 treatment is associated with a high rate of cytometric MRD-negative CR in young and fit patients with previously untreated CLL.

Abstract: Background: the Registro Italiano Trombocitemie (RIT) was activated mainly to evaluate the diagnosis and therapy appropriateness in the thrombocythemic patients with Ph-negative myeloproliferative neoplasm (MPN) observed in the adhering centers. Objective: to evaluate how the diagnostic and therapeutic approach changed in the RIT patients diagnosed with thrombocythemic MPN in the last two decades. Methods: the RIT centers registered by a web-based system during the years 2005-2014 their thrombocythemic MPN patients, and semesterly updated their follow-up data. For patients diagnosed before 2005, the data on diagnosis and prior follow-up were retrospectively collected. The diagnostic process and the initial treatment (started into the first year after diagnosis) were comparatively analyzed in the patients diagnosed before and after 2005. Results: the RIT centers registered 2629 patients. 2388 of them, object of this analysis, were diagnosed between1995 and 2014: 1098 (46%) in the decade 1995-2004 (Group I), and 1290 (54%) in the decade 2005-2014 (Group II). The diagnostic process in the patients of Group II and Group I included bone marrow biopsy (BMB, performed into 1 year and before any cytoreduction): 85% vs 80%, p 〈 0.001; clonality tests (JAK2 and/or others): 80% vs 9%, p 〈 0.001; cytogenetic evaluation: 55% vs 57%, p 0.58; abdominal echography: 46% vs 41%, p 0.016. The patients of Group II, as compared with those of Group I, showed a similar gender distribution (M/F ratio 0.61 vs 0.65, p 0.452), and had at diagnosis: a higher age (median 60 vs 57 years, p 〈 0.001; age 〉 60 years in 50% vs 45% of cases, p 〈 0.01); a similar rate of prior thrombosis (19% vs 19%), prior hemorrhage (3% vs 4%), CVRFs 69% vs 66%), splenomegaly (25% vs 25%), and hepatomegaly (22% vs 24%); a lower rate of disease-related symptoms (36% vs 40%, p 0.04); a higher rate of comorbidities (55% vs 51%, p 0.03). Moreover, they had: a lower platelet (PLT) count (median 737 vs 775 x 109/L, p 〈 0.001; 〈 600 x 109/L in 22% vs 14% of cases, p 〈 0.001); a similar white blood cell (WBC) count (median 8.6 vs 8.5 x 109/L; 〉 10 x 109/L in 28% vs 26% cases); a similar median levels of hematocrit (HCT %, in females 41.4 vs 41.0; in males 44.7 vs 44.6) and hemoglobin (Hb g/dL, in females 13.8 vs 13.6; in males 15.0 vs 14.9). The BMB, revised according to the WHO 2008 criteria, showed a not different distribution (p 0.21) of ET (64% vs 61%), ep-PMF (16% vs 17%), PMF (3% vs 2%), PV (4% vs 4%), and U-MPN (13% vs 16%. The JAK2 V617F mutation in patients of Group II (at diagnosis) and of Group I (after diagnosis) was found in 62% and in 58% of tested cases (p 0.054), respectively. The patients at high standard thrombotic risk were 58% vs 52%, p 0.004. In the patients of Group II and Group I the distribution of the treatment started into the first year was significantly different (p 〈 0.001): AntiPLT 29% vs 24%, CYT 13% vs 16%, CYT+AntiPLT 49% vs 46%, CYT ± AntiPLT 62% vs 62%, AntiPLT ± CYT 78% vs 69%. The treatment CYT ± AntiPLT was started in the patients at high standard thrombotic risk with a rate of 81% vs 80%, respectively, and in the patients at low standard thrombotic risk in 37% vs 43% of cases, respectively. The initial treatment CYT±AntiPLT was related, in multivariate analysis, both in patients of Group II and Group I, with older age ( 〉 60 and 40-60 vs 〈 40 years, p 〈 0.001), higher PLT count ( 〉 1000 and 700-1000 vs 〈 700 x 109/L, p 〈 0.001), prior thrombosis (p 〈 0.001), symptoms (p 〈 0.001). Noteworthy, no relationship was found with JAK2 mutation, and WHO diagnosis. Conclusion: in the studied thrombocythemic MPN patients the real-life diagnostic approach was improved after 2005 not only due to the routine use of JAK2 tests, but also due to the higher rate of BMB done (85% vs 80%). The appropriateness of the cytoreductive treatment (CYT±AntiPLT started into one year from diagnosis) remained high in patients at high standard thrombotic risk (over 80% of cases were treated). Concomitantly, the inappropriate use of the cytoreductive drugs in patients at low standard thrombotic risk appreciably decreased (from 43% to 37% of cases). Moreover, it has to be remarked that the therapeutic approach was significantly influenced not only by older age and prior thrombosis, but also by thrombocytosis (PLT count 〉 700 x 109/L), disease-related symptoms, and inconstantly by leukocytosis and CVRFs.

Abstract: In essential thrombocythemia (ET) patients, history of thrombosis and age over 60 y are validated risk factors for occurrence of thrombosis during the follow-up. Leukocytosis, JAK2 V617F mutation, cardiovascular (CV) general risk factors, and male gender are candidate risk factors for thrombosis. The thrombocytosis, a constitutive abnormality in ET, is associated with both thrombotic and hemorrhagic complications. Aim To evaluate in a large cohort of ET patients the potential relationship between the thrombosis history and the main clinical and biological characteristics at diagnosis, i.e. before any interference of cytoreductive treatment. Methods A cohort of ET patients (PVSG or WHO criteria) of the Registro Italiano Trombocitemie (RIT) was retrospectively analyzed through logistic regression models. Results A total of 977 patients, 387 males and 590 females, presented at diagnosis: median age 56 y (43% with age 〉 60 y), median PLT count 783 x 109/L (33% with low thrombocytosis, 〈 700 x 109/L), median WBC count 8.8 x 109/L (29% with leukocytosis, 〉 10 x 109/L), median HCT 42.6% (high HCT: 〉 47% in 24% of the males and 〉 44% in 23% of the females), CV general risk factors in 69% of cases (one of smoking, hypercholesterolemia, hypertriglyceridemia, hypertension, diabetes, obesity, CV disease, familiarity for thrombosis), bone marrow fibrosis grade 0 in 67% of cases, JAK2 V617F mutation in 56% of the 399 tested patients. The history of thrombosis (arterial in 74% of cases) was reported in 194 (19.9%) patients. The history of thrombosis in univariate analysis was significantly related to: age 〉 60 y (p 0.001), male gender (p 0.009), CV general risk factors (p 0.002), low thrombocytosis (p 0.000), leukocytosis (p 0.003), high HCT (p 0.004), and JAK2 V617F mutation (p 0.008). No relationship was found with bone marrow fibrosis. In multivariate analysis a relationship was confirmed between thrombosis history and age 〉 60 y (p 0.023), male gender (0.046), CV general risk factors (0.039), low thrombocytosis (p 0.004), leukocytosis (0.019), and JAK2 V617F mutation (p 0.033). The rate of thrombosis history in the patients without both low thrombocytosis and leukocytosis (11%, 49/428) resulted significantly lower (p 0.0001) than in the patients with leukocytosis (24%, 54/224), the patients with low thrombocytosis (27%, 71/266), and the patients with both low thrombocytosis and leukocytosis (34%, 20/59). Conclusion In this cohort of ET patients the rate of thrombosis history in multivariate analysis is significantly related to various clinical and biological characteristics at diagnosis, including low thrombocytosis (PLT 〈 700 x 109/L), leukocytosis (WBC 〉 10 x 109/L), JAK2 V617F mutation, age 〉 60 y, male gender, and CV general risk factors.

Abstract: Background: Proteasome inhibitor (PI)-based induction and consolidation proved to be effective in newly diagnosed multiple myeloma (NDMM) patients (pts) eligible for melphalan 200 mg/m2-autologous stem cell transplant (MEL200-ASCT). High response rates have been reported with the second-generation PI Carfilzomib in combination with Lenalidomide-dexamethasone (KRd) or Cyclophosphamide-dexamethasone (KCd). Aims: The primary aim was to evaluate the efficacy and safety of KRd induction-ASCT-KRd consolidation (KRd-ASCT-KRd) vs 12 cycles of KRd (KRd12) vs KCd induction-ASCT-KCd consolidation (KCd-ASCT-KCd). Methods: NDMM pts ≤65 years were randomized (1:1:1; stratification ISS and age) to: KRd-ASCT-KRd: 4 28-day cycles with KRd induction (Carfilzomib 20/36 mg/m2 IV days 1,2,8,9,15,16; Lenalidomide 25 mg days 1-21; dexamethasone 20 mg days 1,2,8,9,15,16) followed by MEL200-ASCT and 4 KRd consolidation cycles; KRd12: 12 KRd cycles; KCd-ASCT-KCd: 4 28-day induction cycles with KCd (Carfilzomib 20/36 mg/m2 IV days 1,2,8,9,15,16; Cyclophosphamide 300 mg/m2 days 1,8,15; dexamethasone 20 mg days 1,2,8,9,15,16) followed by MEL200-ASCT and 4 KCd consolidation cycles. Thereafter, pts were randomized to maintenance with Lenalidomide alone or plus Carfilzomib. Centralized minimal residual disease (MRD) evaluation - 8-color second generation flow cytometry, sensitivity 10-5 - was performed in pts achieving ≥very good partial response (VGPR). Endpoints were pre-maintenance stringent complete response (sCR) and MRD negativity in intention-to-treat (ITT) analysis. Data cut-off was May 30, 2018. Results: 474 NDMM pts were randomized (KRd-ASCT-KRd, n=158; KRd12, n=157; KCd-ASCT-KCd, n=159) and analyzed. Pts characteristics were well balanced. Median follow-up was 20 months. Depth of response improved during treatment (Figure). By ITT analysis, rates of pre-maintenance sCR was similar between KRd-ASCT-KRd (41%) and KRd12 (42%), and significantly higher than with KCd-ASCT-KCd (30%; P value KRd-ASCT-KRd vs KCd-ASCT-KCd=0.047; P value KRd12 vs KCd-ASCT-KCd=0.028). Similarly, rate of ≥CR was 49% with KRd-ASCT-KRd, 52% with KRd12 and 38% with KCd-ASCT-KCd (P value KRd-ASCT-KRd vs KCd-ASCT-KCd=0.041; P value KRd12 vs KCd-ASCT-KCd=0.014) and rate of ≥CR+unconfirmed CR (missing immunofixation confirmation) raised to 60% vs 63% vs 46% in the 3 groups, respectively; rate of ≥VGPR was 88% with KRd-ASCT-KRd, 86% with KRd12 and 74% with KCd-ASCT-KCd (P value KRd-ASCT-KRd vs KCd-ASCT-KCd=0.002; P value KRd12 vs KCd-ASCT-KCd=0.008). In multivariate analysis, the main factor affecting probability of achieving ≥VGPR, ≥CR or sCR was treatment with KRd-ASCT-KRd or KRd12 vs KCd, with no significant impact of ISS Stage or FISH abnormalities. In ITT analysis (MRD missing [31/395 VGPR pts, 8%] and 〈 VGPR were considered as MRD positive), MRD negativity was again similar with KRd-ASCT-KRd (58%) and KRd12 (54%) and significantly higher than with KCd-ASCT-KCd (41%; P value KRd-ASCT-KRd vs KCd-ASCT-KCd=0.004; P value KRd12 vs KCd-ASCT-KCd=0.023); 82% vs 78% vs 88% of pts in the 3 groups, respectively, could maintain extended MRD negative status with 2 MRD negative results obtained apart ≥6 months (either pre-ASCT and post consolidation or post consolidation and during maintenance). During treatment (excluding ASCT) the most frequent grade 3-4 AEs were neutropenia (KRd-ASCT-KRd 20%, KRd12 10%, KCd-ASCT-KCd 16%), thrombocytopenia (KRd-ASCT-KRd 15%, KRd12 8%, KCd-ASCT-KCd 13%) and infections (KRd-ASCT-KRd 14%, KRd12 12%, KCd-ASCT-KCd 13%). Grade 3-4 dermatologic AEs (KRd-ASCT-KRd, 5% with KRd12 12%, KCd-ASCT-KCd 1%), increase in liver enzymes (KRd-ASCT-KRd 9%, KRd12 10%, KCd-ASCT-KCd 1%) and hypertension (KRd-ASCT-KRd 3%, KRd12 8%, KCd-ASCT-KCd 3%) were more frequent with KRd12. Rates of grade 3-4 cardiac AEs (KRd-ASCT-KRd 3%, KRd12 2%, KCd-ASCT-KCd 4%) and thrombosis (KRd-ASCT-KRd 1%, KRd12 2%, KCd-ASCT-KCd 2%) were below 5% in all arms. Discontinuation for AEs was similar in the 3 arms (KRd-ASCT-KRd 6%, KRd12 8%, KCd-ASCT-KCd 7%). Conclusions: Rates of MRD negativity, sCR, ≥CR, ≥VGPR were significantly higher with KRd-ASCT-KRd and KRd12 vs KCd. At present, no differences in MRD and overall best response (sCR, ≥CR, ≥VGPR) were noticed between KRd-ASCT-KRd and KRd12; longer follow-up is needed to evaluate survival. Treatment was well tolerated. Updated data will be presented at the meeting. Figure. Figure.

Abstract: Despite the improvement of therapeutic regimens, several patients with multiple myeloma (MM) still experience early relapse (ER). This subset of patients currently represents an unmet medical need. Experimental Design: We pooled data from seven European multicenter phase II/III clinical trials enrolling 2,190 patients with newly diagnosed MM from 2003 to 2017. Baseline patient evaluation included 14 clinically relevant features. Patients with complete data (n = 1,218) were split into training (n = 844) and validation sets (n = 374). In the training set, a univariate analysis and a multivariate logistic regression model on ER within 18 months (ER18) were made. The most accurate model was selected on the validation set. We also developed a dynamic version of the score by including response to treatment. Results: The Simplified Early Relapse in Multiple Myeloma (S-ERMM) score was modeled on six features weighted by a score: 5 points for high lactate dehydrogenase or t(4;14); 3 for del17p, abnormal albumin, or bone marrow plasma cells & gt;60%; and 2 for λ free light chain. The S-ERMM identified three patient groups with different risks of ER18: Intermediate (Int) versus Low (OR = 2.39, P & lt; 0.001) and High versus Low (OR = 5.59, P & lt; 0.001). S-ERMM High/Int patients had significantly shorter overall survival (High vs. Low: HR = 3.24, P & lt; 0.001; Int vs. Low: HR = 1.86, P & lt; 0.001) and progression-free survival-2 (High vs. Low: HR = 2.89, P & lt; 0.001; Int vs. Low: HR = 1.76, P & lt; 0.001) than S-ERMM Low. The Dynamic S-ERMM (DS-ERMM) modulated the prognostic power of the S-ERMM. Conclusions: On the basis of simple, widely available baseline features, the S-ERMM and DS-ERMM properly identified patients with different risks of ER and survival outcomes.

Abstract: Introduction: Multiple myeloma (MM) is still an incurable disease and patients may relapse despite achievement of complete remission (CR). Minimal residual disease (MRD) assessment by multiparameter flow cytometry (MFC) on bone marrow (BM) is a sensitive diagnostic tool to measure response and is highly predictive of outcome in MM as previously reported. The aim of this study is to evaluate the role of MRD monitoring by MFC in MM patients receiving novel agents with or without autologous stem cell transplantation (ASCT) and to investigate the efficacy of treatments by using MRD-negativity as a deeper response criteria. Methods: The RV-MM-COOP-0556 (EMN02/HO95 MM) study is a phase III, randomized, trial including newly diagnosed MM patients ≤ 65 years. All subjects received 4 cycles of Bortezomib-Cyclophosphamide-Dexamethasone (VCD) induction, followed by Cyclophosphamide chemotherapy and subsequent stem cell mobilization and collection. Afterward, patients were randomized to receive 4 cycles of Bortezomib-Melphalan-Prednisone (VMP) vs one or two cycles of High-Dose-Melphalan (HDM) followed by ASCT. After intensification patients were secondly randomized to receive two cycles of consolidation with Bortezomib-Lenalidomide-Dexamethasone (VRD) vs no consolidation, followed by Lenalidomide maintenance in both arms. Patients who achieved CR/sCR according to IMWG criteria (Rajkumar et al. Blood 2011) after intensification/consolidation treatment, were eligible for the MRD sub-study. MRD analysis by MFC was performed on BM samples after intensification/consolidation, after 6 courses of maintenance, and thereafter every 6 months until progression, to detect monoclonal plasma cells (PCs). Here, we used a double antibody combination (CD138Fitc/CD20PerCp-Cy5.5/CD117APC/CD45APC-H7/CD38PE-Cy7; cyKappaFitc/cyLambdaPE/CD19PerCp-Cy5.5/CD56APC/CD45APC-H7/CD38 PE-Cy7): one tube was employed to obtain PCs quantification, the other one to validate PCs clonality. MRD-negativity was defined when 〈 20 clonal PCs were detected among ≥2.000.000 leukocytes ( 〈 0.001%). Results: One hundred-eleven Italian patients (58 male/53 female) with a median age of 56 years (IQR 52-62) entered MRD sub-study. Sixteen (14%) were ISS stage III, 24 (22%) had high-risk cytogenetic profile and 10 (9%) had LDH levels higher than the upper normal limit. Forty-five patients (40%) received VMP as intensification and 66 (60%) underwent ASCT, thereafter 65 (58%) received VRD consolidation, 24 after VMP and 41 after ASCT. The median follow-up were 28.7 and 17 months from starting treatment and from MRD enrollment, respectively. After intensification/consolidation, 4 patients were not evaluable for MRD due to unsuitable samples, MRD negativity rate was 79% (85 out of 107 evaluable patients) and was independent from the intensification therapy: actually 50/63 patients who received ASCT and 35/44 patients who received VMP achieved MRD negativity. Within MRD-negative patients, 48/85 (56%) received VRD consolidation without major differences between VMP and ASCT. With the limitation related to the shorter follow-up, depth of response further improved during maintenance: 11/22 (50%) of MRD-positive patients became MRD-negative, independently from previous intensification therapy. Conclusions: MRD detection by MFC is a feasible technique in MM and allows to detect residual tumor cells among CR and sCR patients. Preliminary MRD results show that, in patients achieving CR, intensification with VMP or ASCT induced comparable rates of MRD-negativity and maintenance with Lenalidomide further improved depth of response in both arms. Longer follow-up is needed to correlate MRD status to prognosis and clinical outcome and to evaluate the role of maintenance therapy in increasing the quality of response.

Abstract: The extensive use of new drugs in multiple myeloma (MM) allowed the achievement of unprecedented levels of cytoreduction and major advantages in survival rates, though almost all patients still relapse after a successful treatment. PCR-based minimal residual disease (MRD) studies are powerful prognostic tools, able to indentify patients at high risk of relapse. Thus, there is a growing interest in MRD to modulate therapy also in MM, as already happens in other lymphoid neoplasms. However available reports have a too short follow-up to be conclusive. In particular some points need to be addressed: 1) which is the long-term outcome of patients achieving molecular remission (MR) in the absence of further treatment? 2) What is the prognostic impact of MR loss? 3) How long is the window between MR loss and clinical relapse? These issues have been addressed based on the mature results of the GIMEMA VEL-03-096 trial [EudraCT Number 2004-000531-28], which currently has a median follow-up (mFU) of 93 months. Patients and methods Inclusion criteria and treatment schedule have been already reported [Ladetto et al., J Clin Oncol 2010]. MRD was assessed on bone marrow at diagnosis, study entry, after two VTD courses, at the end of treatment and then every six months up to clinical relapse. Patients underwent MRD detection using both qualitative nested PCR and Real Time Quantitative (RQ)-PCR, employing immunoglobulin heavy chain-derived patient specific primers, as described [Voena et al., Leukemia 1997; Ladetto et al., Biol Bone Marrow Transpl 2000; van der Velden et al., Leukemia 2007] . MR was defined as negative MRD results by nested-PCR or less than 1EE-04 by RQ-PCR. Loss of MR was defined as an increase of MRD levels of at least one log in consecutive samples at whenever timepoint. For survival analysis duration of response (DOR), progression-free survival (PFS), time to next treatment (TNT) and overall survival (OS) rates were used, as detailed in IMWG criteria [Rajkumar et al., Blood 2011]. Results Thirty-nine patients were enrolled. So far 27 serological progressions, 22 clinical relapses needing salvage treatment and 12 deaths (two non-MM-related) were observed. Median PFS was 60 months, median TNT 67 months and OS at mFU was 64%. 270 of the planned samples for MRD monitoring (86%) were actually received by the centralized lab. Currently, 26 MR and 11 MR losses have been registered. The achievement of MR was strongly associated with a better outcome, in terms of median DOR (62 vs 9 months, p 〈 0.001), PFS (67 vs 22 months, p 〈 0.001), TNT (108 vs 30 months, p 〈 0.001) and resulted significant for OS, too (72% vs 48% at mFU, p=0.04, Figure 1A-B). Moreover, patients with ongoing MR, MR loss or not achieving MR at all showed increasing risk of relapse, respectively (DOR not reached vs 38 vs 9 months, PFS 92 vs 63 vs 22 months, TNT not reached vs 72 vs 30 months, each p 〈 0.001, Figure 2). Interestingly, the time lag between MR loss and clinical relapse for patients achieving and then loosing MR was comparable to that between end of consolidation and clinical relapse for patients never obtaining MR (TNT 19 vs 11 months p=0.34). Finally, analyzing the relationship between MR achievement, MR loss and need for a salvage treatment, of the 26 patients who obtained MR only 11 (42%) received a retreatment at a median time of 42 months (range: 22-87 months). Of these 11 clinical relapses, 7 were anticipated by a molecular relapse (64%), occurring at a median time of 9 months (range: 2-39 months). The 4 relapses not anticipated by MR loss occurred in cases with inadequate follow-up sampling or at least two years after the end of the planned molecular follow-up. Conclusions Besides confirming the strong prognostic value of PCR-based MRD monitoring in MM, our long-term results indicate the following: 1) the 42 months TNT of patients achieving MR underlines the excellent disease control of MM patients once obtained MR; 2) the occurrence of MR loss heralds relapse, with a TNT from MR loss comparable to TNT of patients not achieving MR; 3) there is a 9 months lag between MR loss and need for salvage treatment. These observations will have increasing relevance considering that ongoing methodological developments will allow effective MRD monitoring in the vast majority of MM patients.
