Confirmation of the Mantle Cell Lymphoma International Prognostic Index (MIPI) in An Independent Prospective Patient Cohort.

Abstract Abstract 138 Background: The Mantle Cell Lymphoma (MCL) International Prognostic Index (MIPI) has been recently developed as first prognostic index especially designed for patients with advanced stage MCL (Hoster et al., Blood 2008). The MIPI is based on four easily available prognostic factors (age, ECOG performance status, leukocyte count, and LDH). It was internally validated using a bootstrap strategy, and several authors reported its validity on larger patient cohorts (Salek et al., ASH 2008, Geisler et al., EHA 2009). We evaluated the prognostic relevance of the MIPI using the pooled data of two currently recruiting randomized trials (MCL Younger and MCL Elderly) of the European MCL Network (Dreyling et al., ASH 2007). Methods: Outcome parameters were primarily overall survival (OS) and secondarily time to treatment failure (TTF). Kaplan-Meier curves according to the MIPI prognostic groups were compared by means of the log rank test and univariate Cox regression. We checked the value of the MIPI prognostic factors within multiple Cox regression. We also evaluated the simplified MIPI and exploratively included patients with stage II into the analyses. Since randomization is ongoing, all analyses were blinded for treatment arms. Results: Currently, 606 patients with advanced stage MCL were evaluable, 317 in MCL Younger and 289 in MCL Elderly. Median age was 63 years (range 32 – 87), 6% had an ECOG performance status > 1, median LDH/ULN ratio was 0.95 (0.29 – 12.2), and median leukocyte count 7,600/μl (1,075/μl – 396,000/μl). The MIPI classified 220 patients (36%) into the low risk (LR), 187 (31%) into the intermediate risk (IR) and 199 (33%) into the high risk (HR) group. With a median follow-up of 19 months and 116 events, the probability for OS at 24 months was 91%, 77%, and 58% for LR, IR, and HR (medians not reached in LR, IR vs. 28 months in HR patients, p < 0.0001), corresponding to a hazard ratio of 2.7 for IR vs. LR (95% CI, 1.5 – 4.9, p = 0.001) and 2.6 for HR vs. IR (95% CI, 1.7 – 4.0, p < 0.0001). The four MIPI prognostic factors were independently prognostic for OS (p < 0.0001 each). In MCL Younger, the distribution to LR, IR, and HR groups was 61%, 23%, and 16%, as compared to 9%, 40%, and 51% in MCL Elderly, the difference reflecting the strong prognostic impact of age. According to preliminary subgroup analyses, 2-years OS rates were 92%, 76%, and 58% (p < 0.0001) in MCL Younger, and 85%, 78%, and 58% (p < 0.0001) in MCL Elderly. The MIPI also separated LR, IR, and HR group with respect to TTF, with medians of 49, 36, and 20 months (p < 0.0001) and a hazard ratio of 2.2 for IR vs. LR (95% CI, 1.4 – 3.4, p = 0.0004) and 2.0 for HR vs. IR (95% CI, 1.4 – 2.8, p = 0.0001). The simplified MIPI classified 36%, 32%, and 33% to LR, IR, and HR groups with high concordance to the MIPI (weighted kappa 0.82). Two-years OS rates were 90%, 79%, 58% for LR, IR, HR according to the simplified MIPI (p < 0.0001) with a hazard ratio of 2.4 for IR vs. LR (95% CI, 1.3 – 4.2, p = 0.003) and 2.5 for HR vs. IR (95% CI, 1.7 – 3.8, p < 0.0001). Inclusion of 32 patients with stage II MCL did not essentially change the results. Discussion: We could confirm the prognostic relevance of the MIPI in a large independent patient cohort treated within current randomized trials. Therefore, the MIPI may be used for risk stratification in future clinical trials, for the comparative interpretation of the results of different trials, for the evaluation of new biological prognostic factors, and may finally lead to risk-adapted treatment decisions in advanced stage MCL.

Abstract BACKGROUND: Genomic aberrations and IGHV mutation status are established prognostic factors in CLL. With TP53, NOTCH1, SF3B1, ATM, MYD88, FBXW7, BIRC3 and POT1 recurrently mutated genes were found in CLL and were discussed to associate with disease characteristics and to affect therapy efficacy and outcome. METHODS: We assessed the incidence and impact of gene mutations in the COMPLEMENT1 trial (1st line Chl vs. O-Chl). Pretreatment samples were available from 376 patients (84.1%) and this cohort was representative of the full trial population. Mutations were analyzed by amplicon-based targeted NGS using Illumina Miseq for all coding exons (TP53, ATM, MYD88, FBXW7, BIRC3 and POT1) or hotspot exons (NOTCH1, SF3B1). Additionally, the exact variant frequency was determined. RESULTS: The incidences of gene mutations were: TP53 8.2%, NOTCH1 14.9%, SF3B1 14.1%, ATM 10.9%, MYD88 2.7%, FBXW7 3.5%, POT1 7.7%, and BIRC3 2.7%. Regarding baseline characteristics, we found significant associations: TP53mut with high ß2MG (p=0.01), 17p- (p<0.01), and unmutated IGHV (p=0.01); ATMmut with high WBC (p=0.02), and 11q- (p<0.01); MYD88mut with mutated IGHV (p=0.02); FBXW7mut with 17p- (p=0.02), and +12q (p<0.01). BIRC3mut was only present in IGHV unmutated cases (p<0.01), was more frequent in 11q- (p<0.01), +12q (p=0.05), and in cases with NOTCH1mut (p=0.05). POT1mut was more frequent in NOTCH1mut cases (p=0.02) without associations with any other baseline parameter. Regarding response to treatment, TP53mut was significantly associated with reduced ORR rate (p<0.01). CR rate was not correlated with mutations in the covered genes. At a median follow-up of 31.7 months, there were 249 (66%) events for PFS and 63 (16.8%) events for OS. O-Chl as compared to Chl resulted in significantly improved PFS (median 22.4 vs. 13.1 months, HR 0.54, p<0.01). In univariate analyses, TP53mut (HR 2.07, p<0.01), NOTCH1mut (HR 1.50, p=0.01) and SF3B1mut (HR 1.66, p=0.01) were associated with shorter PFS, whereas ATM and other candidate genes showed no association (ATMmut: HR 1.40, p=0.07). Analyzing both treatment arms separately, TP53mut had an impact on PFS with Chl and O-Chl treatment (HR 1.92, p=0.04 and HR 2.49, p<0.01). Notably, NOTCH1mut was associated with outcome in O-Chl only (HR 2.01, p<0.01 vs. HR 1.14, p=0.59) resulting in a reduced beneficial effect from the addition of Ofatumumab to Chlorambucil treatment. ATMmut and BIRC3mut mutations were only adverse prognostic factors with Chl monotherapy (ATMmut: HR 1.69, p=0.05 vs. HR 1.35, p=0.27; BIRC3mut: HR 2.84, p=0.04 vs. HR 0.99, p=0.99). OS was reduced significantly only in TP53mut cases (HR 3.69, p<0.01). Of note, none of the MYD88mut cases (n=10) had died within the follow-up period. To identify genomic factors of independent prognostic impact, we performed multivariable Cox regression analyses for PFS and OS including treatment arms, 11q-, +12q, 17p-, IGHV and all candidate gene mutations. For PFS, the following independent prognostic factors were identified: O-Chl (HR 0.46, p<0.01), 17p- (HR 3.14, p<0.01), 11q- (HR 1.57, p=0.01), unmutated IGHV (HR 1.43, p=0.02), TP53mut (HR 1.81, p=0.03), NOTCH1mut (HR 1.63, p<0.01) and SF3B1mut (HR 1.54, p=0.02). Regarding OS, only 17p- (HR 4.07, p<0.01), and unmutated IGHV (HR 1.81, p=0.05) were identified as independent adverse prognostic factors with TP53mut showing a trend (HR 2.14, p=0.10). CONCLUSION: We performed mutational analyses for the 8 most frequent mutated genes in CLL in the COMPLEMENT1 trial evaluating 1st line O-Chl against Chl. An independent prognostic impact was identified for TP53mut, NOTCH1mutand SF3B1mut regarding PFS. Notably, NOTCH1mut affected outcome mainly with O-Chl treatment, whereas ATMmut and BIRC3mut were associated with outcome with Chl monotherapy. In multivariate analysis for OS, none of the gene mutations, but the established parameters IGHV and 17p- had independent prognostic impact.

Introduction. Myelodysplastic Syndrome (MDS) is a disease of the elderly. Apart from IPSS, IPSS-R and WPSS, several indexes incorporating patient comorbidities (such as the MDS CI index- Della Porta et al Haematologica 2011, the HCT-CI index - Sorror et al Blood 2005) and performance status (the GFM index- Itzykson et al Blood 2011) have been used to predict outcome in MDS patients treated with azacytidine (AZA). We sought to investigate the effect of comorbidities on the outcome after AZA in a large group of patients from the MDS registry of the Hellenic MDS Study Group. Methods. The present study has been conducted as a retrospective observational cohort one. It included high-risk MDS and low blast count AML patients treated with AZA from 26 centers in Greece from 2007 to 2018. T-test and ANOVA were used to compare scale variables between two or more groups respectively. Univariate analysis of nominal and scale survival data was performed using Kaplan-Meier survival curves and Cox regression respectively. All variables achieving p<0.05 at univariate analysis were considered eligible for multivariate analysis; the latter was based on Cox regression method. Results. We analyzed 536 consecutive patients. Patient characteristics are depicted in Table 1. The median follow-up period was 27.5±4.8 months. 371 patients received at least four cycles of AZA and 165 patients received less than 4 cycles of AZA. Patients who received ≥4 cycles of AZA did not differ from those who received <4 cycles regarding gender, age, estimated Glomerular Filtration Rate (eGFR), cardiovascular, renal, and tumor comorbidities. Significantly higher IPSS-R and GFM scores at baseline were found in the group of patients receiving < 4 cycles of AZA compared to patients who received ≥ 4 cycles of AZA (p=0.042 and 0.05 respectively), while transfusion dependence at baseline occurred more often in patients who received ≥ 4 cycles of AZA (p=0.039). To assess the prognostic significance of risk factors on leukemia free survival (LFS) and overall survival (OS), univariate and multivariate analysis for the whole population was performed, as well as a landmark analysis for patients who were treated with at least 4 cycles of AZA. ECOG performance status and the presence of peripheral blasts were independent prognostic factors for LFS and OS for the whole cohort analysis while response to AZA and the presence of peripheral blasts were independent prognosticators for LFS and OS in the landmark analysis. In addition, prior low dose cytarabine was an independent adverse prognostic factor for LFS in the landmark analysis. As regards comorbidities, neither of MDS-CI, HCT-CI and GFM systems independently predicted LFS or OS in either analysis, but eGFR with a cut-off of 45 ml/min was a strong and independent prognosticator for LFS and OS in both the standard and the landmark analysis. Kaplan-Meier survival curves regarding LFS and OS at AZA initiation and landmark analysis after 4th cycle of AZA in relation with eGFR are shown in Figure 1. Conclusion. This is the first study to demonstrate the importance of eGFR at baseline as a prognostic marker for LFS and OS in high-risk MDS and low-blast AML patients treated with AZA. The role of comorbidities and PS needs to be further evaluated in this patient group.

Abstract On behalf of the German Low Grade Lymphoma Study Group (GLSG) and the European MCL Network. Background: There is no generally established prognostic classification system for patients with mantle cell lymphoma (MCL), as the International Prognostic Index (IPI) and the Follicular Lymphoma International Prognostic Index (FLIPI) have been developed based on data of patients with diffuse large cell and follicular lymphoma, respectively. Methods: The data of 455 patients with advanced stage MCL treated first-line within three clinical trials of GLSG and European MCL Network have been analyzed to clarify the prognostic relevance of IPI and FLIPI and to derive a new prognostic index of overall survival (OS). Age, sex, ECOG performance status, Ann Arbor stage, B-symptoms, number of extranodal sites, number of involved nodal areas, tumor size, serum LDH activity, WBC count, platelet count, hemoglobin, albumin, β2-microglobulin and cell proliferation (Ki-67) were considered as candidate prognostic factors. Statistical methods included Kaplan-Meier estimates and logrank test for the validation of IPI and FLIPI and multiple Cox regression with backward variable selection for the derivation of the new prognostic index. Results: IPI showed a significant impact on OS, but low-intermediate and high-intermediate risk groups comprised more than two thirds of the patients and were not well separated. According to the FLIPI, only 6% of the patients were classified as low risk and almost two thirds of the patients as high risk, and low and intermediate risk groups were not separated. Four of the candidate prognostic factors were independently associated with OS, namely age, ECOG performance status, LDH and WBC count. The relative risk was 1.42 (95% confidence interval 1.18 to 1.72, p = 0.0002) for an increased age by ten years, 2.01 (1.19 to 3.39, p = 0.0088) for an ECOG greater than one, 1.51 (1.13 to 2.02, p = 0.0059) for a 2 fold elevation of LDH and 2.56 (1.66 to 3.95, p < 0.0001) for a 10 fold increase of WBC count. According to these four parameters, patients could be classified into a low risk (44% of the patients, median OS not reached), an intermediate risk (35%, median OS 51 months), and a high risk group (21%, median OS 29 months). Discussion: IPI and FLIPI showed only modest prognostic discrimination in our external validation data set of patients with advanced stage MCL. In contrast, age, ECOG performance status, LDH and WBC were identified as independent prognostic factors of OS, and three reasonably sized and well separated risk groups were defined. With four clinical prognostic factors readily determined in clinical routine, our new prognostic index (MIPI) is superior to the IPI. Bootstrap validation confirmed the separation of three risk groups, but external validation is still needed. The MIPI may prove to be an important tool to facilitate risk-adapted treatment decisions for patients with advanced stage MCL.

Abstract Background: Patients (pts) withHR-MDS have a median OS of 4 to 6 months (mo) after HMA failure (Prebet et al, J Clin Oncol 2011) and no approved salvage therapy. Development of new therapeutics for this population will benefit from the availability of surrogate endpoints and markers that can predict survival. Gore et al established response to azacitidine (Vidaza®) in first-line therapy for HR-MDS as a reasonable surrogate to predict survival (Gore et al, Haematologica 2013). Rigosertib, a novel dual PI3K/PLK pathway inhibitor, has been shown to reduce bone marrow blasts (BMBL) in these pts (Seetharam et al, Leuk Res 2012). Silverman et al described complete or partial bone marrow (BM) response, or stabilization after 4-8 weeks (wks) of treatment with rigosertib as a potential surrogate for predicting survival in pts with HR-MDS after failure of primary HMA therapy (Silverman et al, Hematol Oncol 2014). We tested this hypothesis in the context of a randomized Phase III trial. Methods:Pts with HR-MDS were randomly assigned 2:1 to rigosertib or best supportive care (BSC) after progressing on, failing to respond to, or relapsing after HMA treatment. BM aspirates were assessed pretreatment, at 4 weeks and at 8-week intervals thereafter. Central slide review was undertaken in a representative population of samples. The BMBL response at each time point was assessed using the following definitions: bone marrow complete response (mCR) = BMBL ≤ 5% and decrease of ≥ 50% from baseline; bone marrow partial response (mPR) = BMBL decrease from baseline of ≥ 50%, but BMBL still > 5%; stable disease (SD) = BMBL decrease or increase from baseline of < 50%; progressive disease (PD) = BMBL increase from baseline of ≥ 50% by an absolute minimum of 5%; Not evaluable (NE). Results:Bone marrow assessment was carried out in 156 patients (pts) on the rigosertib arm and 24 pts on the BSC arm at 4 wks after enrollment, and in 86 and 20 pts, respectively, at 12 wks. The invasive BM procedure was optional on the BSC arm, which accounts for the low number of assessments in this group. BM responses at the 2 time points are presented in Table 1. Since no difference in overall survival was noted between pts who had objective BM response and those who did not progress (ie, stable disease), a landmark analysis was conducted that separated pts who were alive at the 4-wk landmark time into two 4-wk response categories: BM response + SD vs. PD. Results of this analysis in rigosertib-treated patients were statistically significant at p = 0.011, with a hazard ratio (HR) of 0.62 and a median OS (from 4 wks onward) of 9.8 months in the mCR + mPR + SD group vs. 4.6 months in the PD group (Figure 1). Another landmark analysis was conducted at 12-wks. Results of this analysis were also significant (p < 0.001) in rigosertib-treated patients, with an HR of 0.39 and a median OS (from 12 wks onward) of 10.4 months in the mCR + mPR + SD group vs.7.5 months in the PD group (Figure 2). A time-dependent Cox regression of OS by 4-wk BMBL response reinforced the validity of the 4-wk and 12-wk BM assessments as surrogate biomarkers for survival (Table 2). Conclusions: These data suggest that BMBL response at 4 or 12 weeks was correlated with OS in this population of pts with HR-MDS treated with rigosertib after HMA failure and are consistent with previous observations in Phase II studies.

Introduction: Peripheral T cell lymphoma (PTCL) is a very heterogenous disease and corresponds to approximately 15% of all non-Hodgkin lymphoma cases. PTCL is divided into several subtypes, however, PTCL not otherwise specified (PTCL-NOS) is the most frequent, with a proportion of 26% of all PTCL cases. There is a lack of demographic and clinical data about PTCL-NOS in middle- and low-income countries, where patients' access to early diagnosis and otherwise standard care might be suboptimal. The objective of this study is to describe the population of PTCL-NOS patients in Latin America, specifically from the countries conforming the "Grupo Latinoamericano de Linfomas" (GELL), in order to better understand clinical behavior and find possible prognostic factors that might prognosticate overall survival (OS). We specifically evaluated the neutrophil/lymphocyte ratio (NLR) and serum albumin as potential prognostic factors. Methods: An observational, retrospective and analytical study was conducted during the period from January 2000 through January 2018. A total of 200 Latin American patients with a pathological diagnosis of PTCL-NOS were included. Clinical data were gathered from clinical records. NLR ≥4 and serum albumin ≤3.5 g/dl were considered adverse prognostic factors. Median Overall Survival (mOS) and 5-year Overall Survival (5y-OS) rates were estimated using the Kaplan-Meier method. Univariate and multivariate Cox proportional-hazard regression analyses were performed to identify adverse prognostic factors for OS. Data were analyzed and interpreted using STATA 15. Results: A total of 200 patients with a diagnosis of PTCL-NOS were included. 50% of patients were ≥60 years, 57% were male, 50% had ECOG ≥2, 40% had elevated serum Lactate Dehydrogenase (LDH) level, 70% showed stage III/IV disease, bone marrow involvement was present in 37% of patients, B symptoms in 65%, 33% presented with hemoglobin levels <10 g/dL. The International Prognostic Index (IPI) score was high-intermediate in 33% and high in 14% of cases. The Prognostic Index for PTCL-U (PIT) risk score was high-intermediate in 32% and high in 26% of cases. Serum albumin <3.5 mg/dl was seen in 58%, and NLR ≥4 in 37% of patients. Median OS (mOS) for the entire cohort was 0.83 years (95% CI 0.58-1.75) and 5-year OS rate was 31% (95% CI 23-40%). Patients with serum albumin levels <3.5 g/dL had mOS of 0.42 years (95% CI 0.25-0.75) and 5-year OS rate of 20% (95% CI 9-33%), while patients with albumin ≥3.5 g/dL had mOS of 5.1 years (95% CI 0.83-not reached) and 5-year OS rate of 51% (95% CI 36-65%) (log-rank p<0.001). The mOS for NLR <4 was 1.67 years (95% CI 0.75-4.92) with 5-year OS rate of 37% (95% CI 25-48%) while for NLR ≥4, the mOS was 0.58 years (95% CI 0.25-1.00) and 5-year OS rate was 23% (95% CI 12-36%) (log-rank p=0.02). Cox proportional Hazard regression multivariate analyses found serum albumin <3.5 g/dL (HR 1.83, 95% CI 1.10-3.05; p=0.02) and ECOG ≥2 (HR 1.95, 95% CI 1.15-3.30; p=0,01) were associated with a worse OS. Serum albumin remained an adverse prognostic factor for OS after adjustment for the IPI and the PIT scores (HR 1.66, 95% CI 1.01-2.75; p=0.047, and HR 1.70, 95% CI 1.03-2.80; p=0.038, respectively). Conclusion: This multi-institutional Latin American study showed that serum albumin level <3.5 g/dL was an adverse prognostic factor for OS, independent from the IPI and the PIT scores, in Latin American patients with a diagnosis of PTCL-NOS. The survival rates of Latin American patients with PTCL-NOS appear lower than in developed countries.

Abstract Introduction: Lenalidomide (Len) in association with standard Rituximab-CHOP (R2CHOP21) has been shown to be safe and effective in newly diagnosed Diffuse Large B-cell Lymphomas (DLBCL) [Nowakowski et al. JCO 2014, Vitolo et al. Lancet Oncol 2014]. The addition of lenalidomide appears to benefit primarily patients with non-Germinal Center B-cell (non-GCB) phenotype as determined by immunohistochemistry (IHC). These early results led to currently ongoing randomized trial in ABC subtype of DLBCL, however efficacy of R2CHOP in ABC DLBCL as defined by Gene Expression Prophyling (GEP) has not been reported. In the present combined analysis of two independent phase 2 studies, we report the long-term follow-up (FU) outcome in DLBCL patients treated with R2CHOP, comparing GCB and ABC according to Nanostring Platform. Methods: We included all newly diagnosed histologically-confirmed de-novo DLBCL patients enrolled in two R2CHOP21 phase 2 trials, conducted by Mayo Clinic (MC) and Italian Lymphoma Foundation (FIL). Inclusion criteria in the two trials were similar, main differences included: all age and all International Prognostic Index (IPI) vs age between 60 and 80 years old and IPI >1, in MC vs FIL study, respectively. All pts received R-CHOP21 plus Len at 25 mg/day for 10 days/cycle and 15 mg/day for 14 days/cycle in MC and FIL trial, respectively. Cell of origin (COO) was determined by IHC, according to Hans algorithm, and retrospectively, in patients with available pathological material, by Nanostring, performed according to Scott algorithm and Masque-Soler signature in MC and FIL study, respectively. We analyzed the long-term FU outcome in terms of progression-free survival (PFS), time to progression (TTP), overall survival (OS), comparing between GCB and ABC phenotypes according to GEP. Results: A total of 112 DLBCL pts (63 MC, 49 FIL) were included. Main characteristics were: median age 69 years (y) (range 22-87), male 65 (58%) pts, advanced stage III-IV in 94 (84%), B symptoms in 38 (34%), International Prognostic Index (IPI) intermediate-high/high in 71 (63%). At a median follow-up of 5.1 years (y), 5y-PFS was 63.5%, 5y-TTP 70.1% and 5y-OS 75.4%. A total of 32 relapses were observed, with only 2 cases of Central Nervous System (CNS) relapse. Late relapse occurring beyond 3 years was observed in 4 cases (3 cases with GCB phenotype and one case with missing COO data). In a subgroup analysis by IPI 0-2 vs 3-5 were: 5y-PFS, 5y-TTP and 5y-OS were: 69.0% vs 59.0% (p=0.100), 73.2% vs 67.4% (p=0.285) and 82.3% vs 70.2% (p=0.059), respectively. Regarding for COO defined by IHC, GCB phenotype vs non-GCB were 45 (40%) vs 41 (37%) patients respectively; 26 (23%) patients were not evaluable. 5y-PFS, 5y-TTP and 5y-OS were: 52.8% vs 64.5% (p=0.198), 61.6% vs 69.6% (p=0.444) and 68.6% vs 74.1% (p=0.238) in GCB vs non-GCB, defined by IHC, respectively. Regarding Nanostring analysis, GCB vs ABC vs Unclassified (Uncl) were 31 (46%) vs 22 (32%) vs 15 (22%) respectively; 44 pts were not evaluable. 5y-PFS, 5y-TTP and 5y-OS were: 62.3% vs 70.8% vs 64.2% (p=0.645), 68.1% vs 79.8% vs 64.2% (p=0.662) and 76.0% vs 74.8% vs 79.0% (p=0.658) in GCB vs ABC vs Uncl, defined by Nanostring, respectively (Table1, Fig1). Conclusions: The association of Len with R-CHOP21 appears to overcome the negative prognostic impact of ABC phenotype determined by GEP, with high PFS, TTP and OS rate, maintained at a long-term FU analysis.

Abstract Introduction: Epstein Barr virus-positive (EBV+) diffuse large B-cell lymphoma (DLBCL), not otherwise specified (NOS) is a newly recognized entity by the World Health Organization. EBV+ DLBCL, NOS is commonly encountered in Latin American countries and carries a dismal prognosis. Current prognostic models such as the Oyama and the International Prognostic Index (IPI) score have limited prognostic value in this patient population. Therefore, we aim to evaluate the ability of these models to risk stratify patients and propose a novel prognostic model in the largest cohort of Latin American patients with EBV+ DLBCL, NOS. Methods: This retrospective cohort study included patients ≥18 years from six Latin American countries diagnosed and treated at tertiary centers from 2010 to 2020. Hematopathologists at each institution reviewed pathological samples to confirm the diagnosis of EBV+ DLBCL, NOS. We collected clinicopathological data by reviewing the medical records of the patients. The primary endpoint was overall survival (OS), defined as the time from the date of diagnosis until death from any cause or last visit. The secondary endpoint, progression-free survival (PFS), was defined as the time from diagnosis until death, progression, or last visit. Our novel model (Grupo de Estudio Latinomericano de Linfoproliferativos [GELL] Score) includes the Eastern Cooperative Oncology Group (ECOG) performance status ≥2, extranodal involvement >1, serum albumin <3.5 g/dL, serum lactate dehydrogenase (LDH) above the upper limit of normal, and platelet-to-lymphocyte ratio >455. We assigned a value of 1 to each of the abovementioned elements in the score and classified the patients as low (0 points), intermediate (1-2 points), and high (3-5) risk. OS and PFS probabilities were computed with the Kaplan-Meier method and compared with the log-rank test. We used Cox regression to evaluate the proportional hazard ratios (HR) of each score for our study outcomes. The C-index was employed to measure discrimination of each model. We used cross-validation to evaluate the model performance. Results: A total of 154 patients with EBV+ DLBCL, NOS were included in this analysis. The median age at diagnosis was 58 years (range 19-86 years) with a slight male predominance (53%). EBER was positive in all cases (range 1-100%). Clinically, 39% presented ECOG ≥2, 57% had B symptoms, 50% had an extranodal disease as a primary tumor, and 71% had Ann Arbor stage III/IV. Fifty-one percent of the patients had an elevated LDH level, and 43% had albumin <3.5 g/dL. Rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) regimen was administered in 79% of individuals as first-line treatment. The overall response rate was 80% (62% complete response and 18% partial response). With a median follow-up of 61 months, the 5-year OS and PFS rates were 61% and 47%, respectively. The 5-year OS rates of patients with low, intermediate, and high-risk disease according to the GELL score was 90%, 59%, and 33%, respectively (Fig 1A). The 5-year PFS rates were 82%, 39%, and 23%, respectively (Fig 2A). Table 1 shows the Cox regression and the discrimination analysis for each of the scores. The GELL score has the highest discriminatory index for OS and PFS compared to the IPI, Revised-IPI, National Comprehensive Cancer Network-IPI, and the Oyama score (Figure 1 and 2). Conclusions: This study proposes a novel score for risk stratification of patients with EBV+ DLBCL, NOS. The GELL score appears to better discriminate OS and PFS than previous scores. Our results should be validated in an independent prospective cohort. Figure 1 Figure 1.

Abstract Background: Advances in the treatment for multiple myeloma (MM) have dramatically improved outcomes for younger patients. Older adults, particularly those 80 years of age or older at diagnosis, have seen more modest gains. MM incidence increases with age, and as more of the population is living later into life, the segment of the MM population over 80 will continue to grow. In this study, we sought to better understand the characteristics, treatment, and outcomes of older patients with MM. Methods: We identified all patients diagnosed with MM at age 80 or older in the Surveillance, Epidemiology, and End Results Program (SEER) database from 2007-2013 to determine incidence and outcomes. Subset analysis was then performed on patients included in the SEER-Medicare linked database who were enrolled in Medicare Parts A, B, and D to further explore patient characteristics and treatment patterns. Results: The incidence of MM increases over age, peaking after age 80. The annual incidence for those aged 65-69, 70-74, 75-79, 80-84 and 85+ was 24.4, 32.7, 39.5, 42.8 and 36.4 per 100,000, respectively. Based on 2010 US population estimates, approximately 4,500 new cases of MM were diagnosed annually 2007-2013 in patients age 80 or older. In that period, 8,093 cases, approximately 1,150 per year, were reported to SEER. The estimated median overall survival (OS) of these patients was 14 months (95% CI 13.2-14.8). The estimated relative 12 month survival was 58.9% (95% CI 57.4-60.4) compared to their peers without cancer. Of the 8,093 cases of MM reported to SEER during the study period, 2,385 were present in the SEER-Medicare linked dataset. Of these, 225 were identified as smoldering MM using a previously established algorithm (Fiala, et al, JCOCCI, 2018) and excluded leaving 2,160 for the analyses. The median age was 84 (range 80-100) and 55% were female. 81% were white, 13% black or African-American, and 6% another race. At disease presentation, 22% had claims indicating hypercalcemia, 61% renal failure or chronic kidney disease, 59% anemia, and 34% MM bone involvement. The estimated median OS was 13.4 months (95% CI 12.2-15.1). Only 52% of patients had claims indicating they received systemic MM treatment within 6 months post-diagnosis. Nearly all that did received novel agents; 38% received bortezomib-based treatment, 41% immunomodulatory drug (IMID)-based, and 14% both. The others received antineoplastic chemotherapies such as melphalan or cyclophosphamide. Interestingly, bortezomib utilization increased incrementally from 25% of patients treated in 2007 to 62% in 2013 while IMID utilization declined from 67% to 49%. The median OS of those receiving treatment was 21 months (95% CI 18.5-23.1) compared to 6.3 months (95% CI 5.3-7.3) for those who did not (p <0.0001). MM treatment was associated with a 26% decrease in hazard for death (aHR 0.74; 95% CI 0.67-0.82; p < 0.0001) independent of age, race, gender, poverty, comorbidities, and proxy measures of performance status. Outcomes improved for patients in more recent years; the hazard for death decreased by 3% (HR 0.97; 95% CI 0.94-0.99; p = 0.0096) each year 2007-2013. This can be attributed to increasing treatment rates. In 2007, only 41% of patients received treatment compared to 61% in 2013. After controlling for MM treatment, the year of diagnosis was no longer a significant predictor of survival. Conclusions: The outcomes of patients with MM over 80 years old are still relatively poor; nearly half of the patients do not receive systemic treatment and for those who do the median OS is just 21 months. The population over 80, when MM incidence peaks, is projected to triple over the next few decades. It is imperative that we improve our understanding of the needs of this vulnerable subgroup of patients of MM.

Purpose: Hodgkin's lymphoma (HL) is a highly curable disease even in advanced-stage, with >90% of long-term survivors. Currently, the standard of care is ABVD (doxorubicin, etoposide, vinblastine and dacarbazine), as it is less toxic and as effective as other more intensive chemotherapy regimens. Alternatively, BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine and prednisone) has been proposed as front-line intensified regimen with a better initial disease control and prolonged time to relapse when compared to ABVD. However, this advantage is associated with higher rates of severe hematologic toxicity, treatment-related deaths, secondary neoplasms and infertility. To date, the debate regarding which regimen should be preferred as first line for advanced-stage HL is still ongoing. To shed some light on this open question we compared efficacy and safety of both regimens in clinical practice. Patients and Methods: From October 2009 to October 2018, patients with HL stage III-IV treated with either ABVD or BEACOPP escalated (BEACOPPesc) were retrospectively assessed in 7 European cancer centers. Results: A total of 372 consecutive patients were included in the study. One-hundred and ten patients were treated with BEACOPPesc and 262 with ABVD. The baseline characteristics of the two groups did not differ significantly, except for a higher rate of high-risk patients in the BEACOPPesc group in contrast to the ABVD one (47% vs 18%; p= 0.003). Complete response rate (CR) assessed by PET imaging at the end of the second cycle was 67% and 78% for the ABVD and BEACOPPesc group (p= 0.003), respectively. Thirteen patients of the ABVD group achieved stable disease (SD) and 6 had a progression disease (PD). On the other hand, 4 of the patients in the BEACOPPesc group progressed, another 2 interrupted therapy because life-threatening toxicity. At the end of the therapy, CR was 76% in the ABVD group and 85% in the BEACOPPesc group (p= 0.01). A total of 20% patients in the ABVD group and 14% patients in the BEACOPPesc group received consolidation radiotherapy on the mediastinal mass at the dose of 30Gy. After radiotherapy, the number of patients with CR increased to 79% and 87% in the two groups (p= 0.041), respectively. Thirty-nine patients (35%) in the BEACOPPesc group required dose reduction of chemotherapy due to toxicity compared to 12 patients (5%; p= <0.001) in the ABVD group. Overall, the rate of severe toxicities was higher in the BEACOPPesc group in comparison with the ABVD cohort. In particular, there was a significant increased frequency of acute grade 3-4 hematologic adverse events (neutropenia 61% vs 24%; anemia 29% vs 4%; thrombocytopenia 29% vs 3%), febrile neutropenia (29% vs 3%), severe infections (18% vs 3%). Myeloid growth factors were administered to 85% and 59% of patients in the BEACOPPesc group compared to the ABVD group. Blood transfusions were required in 51% and 6% of patients in the BEACOPPesc group compared to the ABVD cohort. Progression during or shortly after treatment occurred in 5 patients in the BEACOPPesc group (4%) and in 16 patients in the ABVD group (6%; p= 0.62). Among the 96 patients who achieved a CR after BEACOPPesc and radiotherapy, 8 relapsed (8%), compared to 29 of 208 patients in the ABVD group (14%; p= 0.04). At a median follow-up period of 5 years, no statistical difference in progression free survival (PFS; p=0.11) and event-free survival (EFS; p=0.22) was observed between the BEACOPPesc and ABVD cohorts. Similarly, overall survival (OS) did not differ between the two groups (p=0.14). The baseline international prognostic score (IPS <3 vs ≥ 3) significantly influenced the EFS with an advantage for the high-risk group treated with BEACOPPesc (Figure 1A; p=0.03), but not the PFS (Figure 1B; p=0.06) and OS (Figure 1C; p=0.14). During the follow-up period, in the BEACOPPesc group one patient developed myelodysplasia and one acute leukemia. Second solid tumors developed in one patient in the ABVD group (lung cancer) and one in BEACOPPesc group (breast cancer). Conclusion: We confirm that the ABVD regimen is an effective and less toxic therapeutic option for advanced-stage HL. Although BEACOPP results in better initial tumor control especially in high-risk patients, the long-term outcome remains similar between the two regimens.

Abstract Abstract 1749 Poster Board I-775 Introduction Both thalidomide (Thal) and 5-azacitidine (Vidaza; AZA) have single-agent activity in patients (pts) with myelodysplastic syndromes (MDS), but there is limited experience with the combination. The addition of Thal to AZA may improve efficacy, but tolerability of the combination may be limited by side-effects. Patients and Methods This analysis included all evaluable pts on the Ph I/II Australasian Leukaemia and Lymphoma group (ALLG) MDS3 study of Thal and AZA. Pts were eligible if they had any FAB subtype of MDS; those with RA and RARS also required clinically significant cytopenias. Pts were excluded if they had previously received Thal or its derivatives or any demethylating agent. All pts were treated with Thal 50mg/d for the first 28d increasing to 100mg/d for a max of 12 Mo treatment and AZA 75mg/m2/d x7d every 28d until progression or prohibitive toxicity. The protocol specified dose delays or reductions for treatment-related toxicities. Results A total of 80 pts have been enrolled, with 41 treated between 7/08 – 7/09 currently evaluable. Median age is 68.5y (42-81) with 66% male. FAB MDS category was RA 15%, RARS 10%, RAEB 46%, RAEB-t 10% and CMML 17% with IPSS low 12%, intermed-1 37%, intermed-2 34% and high 12%. Median baseline Hb 88g/L (71-127), ANC 1.91×10 9/L (0.06-87.65) and platelets 75 ×10 9/L (10-399). Median time post diagnosis was 9 Mo. Seventeen pts (41%) remain on treatment with AZA alone (n=3) or both agents (n=14) with a median follow-up of 208d (60-297d). For those still on Thal and AZA median exposure to Thal is 209d (60-297d), with a median 7 cycles of AZA (2-9). For those 27 ceased Thal median exposure was 49d (17-220d) and of 24 ceasing AZA, median number cycles was 2 (1-8). Of 27 pts ceasing one (n=3) or both (n=24) agents; 7 withdrew consent, 3 at investigator decision, 4 for toxicity, 6 progressive disease, 1 lack of efficacy, 2 death (1 respiratory failure in setting of PD and WCC>300, 1 sepsis) and 4 unknown. There were 3 additional deaths within 28d of ceasing study therapy (all with PD); 2 due to sepsis and 1 intracranial haemorrhage. No pt experienced peripheral neuropathy Gr3 or worse. During cycle 1 of the first 40 consecutive patients on treatment, there were 18 episodes of Gr3+ non-haematologic toxicity in 13 patients; this was more likely in those with ECOG 2 (67% v 26%, p=0.053), age>65y (39% v 19%, p=0.175) and baseline ANC'0.5 (75% v 21%, p=0.008). Most of these events were infection related (a recognised risk of underlying MDS and of AZA alone); others occurred on only one occasion each (syncope, postop hemorrhage, respiratory disorder, renal failure, abdominal pain, pain, thrombosis and hypokalemia). Conclusions The combination of Thal 50-100mg/d and standard dose AZA is feasible without unexpected toxicity. Infections are common in the first cycle, particularly in pts with baseline neutropenia or impaired performance status. An updated toxicity analysis will be presented.
