Abstract Background: Diffuse large B-cell lymphoma (DLBCL) is curable for the majority of patients treated with anthracycline based immunochemotherapy (IC). However, up to 40% of patients will relapse or require retreatment of DLBCL and outcomes are poor in this setting. Here we examine the incidence, treatment patterns and outcomes of relapsed DLBCL in the R-CHOP era. Methods: Patients were prospectively enrolled in the University of Iowa / Mayo Clinic SPORE Molecular Epidemiology Resource (MER) within 9 months of diagnosis and followed for relapse, retreatment, and death. Clinical management at diagnosis and subsequent therapies were per treating physician. This analysis includes patients with DLBCL or primary mediastinal B-cell lymphoma (PMBCL) who underwent front-line anthracycline based IC; patients with primary CNS lymphoma or PTLD were excluded. All relapse and re-treatments were verified by medical record review. Response to front-line therapy was retrospectively classified per 2007 Revised Response Criteria for Malignant Lymphoma from available clinical and radiology records. Unplanned consolidative radiation (RT) without biopsy proven disease after achieving PR from IC (N=21) was not classified as a relapse. Results: 1039 patients with newly diagnosed DLBCL or PMBCL and treated with IC were enrolled in the MER from 2002-2012. Median age at diagnosis was 62 years (range 18-92) and 577 patients (56%) were male. 647 patients (63%) had stage III/IV disease and IPI at diagnosis was 0-1 in 350 patients (34%), 2 in 305 patients (29%), 3 in 250 patients (24%) and 4-5 in 134 patients (13%). At a median follow-up of 59 months (range 1-148), 258 patients had relapse or retreatment of DLBCL of which 184 (71%) died. Incidence of relapse was 21.7% (95% CI: 19.3%-24.4%) at 2 years and 25.5% (95% CI: 22.9%-28.5%) at 5 years. In addition, the incidence of lymphoma related death without documented relapse or retreatment was 4.7% (95% CI: 3.6%-6.2%) at 2 years. At first relapse, 174 patients (67% of relapsed) received platinum based salvage therapy with 90 (52%) subsequently proceeding to autologous stem cell transplant (ASCT). 22 patients received CNS directed systemic therapy at relapse with 9 (41%) proceeding to transplant, and 43 received non-platinum-based salvage systemic therapy with 7 proceeding to transplant (17%), 15 patients received RT only as 2nd line therapy, and 4 were untreated. At a median follow-up of 56 months (range 6-121) post-transplant, 39 of 107 patients who underwent transplant remain in remission with a 2-year post-transplant progression-free survival of 45% (95% CI 37%-56%). Response to front-line IC was predictive of post-relapse outcome. Survival post-relapse was superior in the 162 patients with responsive disease (CR or PR) at the end of front-line IC (median OS 21.0 months) compared to the 88 patients who had stable or progressive disease (median OS 6.8 months, HR = 2.33, 95% CI: 1.73-3.14 p<0.0001). Transient response in midst of front-line IC was similar to no response. Patients achieving a CR or PR to front-line IC were more likely to proceed to ASCT at relapse (55%) compared to patients with either SD or PD at the end of front-line IC (25% and 17% respectively, p<0.0001). Other factors associated with poor survival at first relapse were relapse within 12 months of diagnosis (HR = 2.24, 95% CI: 1.57-3.18, p<0.0001), IPI at diagnosis of 3-5 (HR=1.51, 95% CI: 1.13-2.03, p=0.0058), and age > 60 (HR =1.51, 95% CI: 1.12-2.03, p=0.0064). There was no difference in survival at first relapse by cell of origin (HR = 1.13, 95% CI: 0.74-1.72, p=0.59). Conclusions: Most patients undergo therapy after relapsed/refractory DLBCL but only one-third receive ASCT. Outcomes following all treatments for relapsed/refractory DLBCL remain poor. Factors associated with adverse outcomes include refractory to front-line therapy, early relapse, baseline IPI and advanced age. These outcomes provide relevant historical control for the many novel agents being tested in this unmet need. Figure 1. Figure 1. Disclosures Farooq: Kite Pharma: Research Funding.

Abstract Abstract 2693 Background: Aggressive B-cell NHL harboring a c-MYC rearrangement (myc+) with or without t(14;18) is associated with shortened PFS and overall survival (OS) (Savage, Blood 2009; Johnson, Blood 2009). Clinical presentation, risk-assessment, and therapies vary among pts and institutions. We reviewed pts with myc+ and double hit NHL treated at the Ohio State University (OSU) from Aug 2008-Jan 2012 to determine factors associated with prolonged PFS and OS. Methods: Pts with de-novo B-cell NHL who were myc+ by FISH break-apart probe were included. Pts with Burkitt's, follicular, and transformed NHL were excluded. Most pts were also evaluated for presence of t(14;18) by FISH, and those myc+ pts with t(14;18) were classified as double hit NHL. Response was determined by PET/CT at the completion of first-line therapy. Associations between myc+ and clinical characteristics were described. PFS and OS were defined from date of diagnosis to date of relapse or death. Univariable and multivariable Cox regression models were performed to assess relationships of selected clinical variables with PFS and OS. Results: Of 49 myc+ pts, 55% were male, and median age at diagnosis was 62 (range: 23–83). Morphologically, 30 pts had diffuse large B-cell lymphoma (DLBCL), 10 pts had B cell lymphoma unclassifiable with features intermediate between diffuse large B cell and Burkitt lymphoma (BCLU), and 9 pts had high grade NHL not otherwise specified. Twenty-eight pts had ECOG performance status ≤1, and 40 pts had stage III-IV disease. Twelve pts had bone marrow involvement, and 26 pts had bulky disease ≥5cm. IPI was ≥3 in 24 pts, and median Ki-67 was 90% (range: 45–100). Twenty-nine of 43 assessed pts (67%) were positive for t(14;18). Therapies included R-CHOP (N=17), R-EPOCH (N=17), Burkitt's-like (ie, R-HyperCVAD, R-CODOXM/IVAC, or R-CHOP with high dose methotrexate; N=11), or other (N=4). No pts underwent autologous transplant in first remission. Twenty-nine pts (59%) achieved a complete response (CR), 2 pts had a partial response, 1 pt had stable disease, 8 pts had progressive disease (PD), and 9 pts died before response assessment (5 pts after cycle 1, 3 pts after cycle 2, and 1 pt after cycle 3). With a median follow-up of 26.2 months (mos; range: 4.8–45.0), the median PFS for all pts was 16.6 mos (95%CI: 9.6 - not reached=NR), and median OS was 37.7 mos (95%CI: 15.7–NR). Median PFS was 3.9 mos for pts without CR vs. not yet reached in pts with CR (p<0.00001). Median OS was 7.0 mos for pts without CR vs. not yet reached for those with CR (Figure 1A; p<0.00001). CR pts were treated with R-CHOP (N=12), R-EPOCH (N=9), Burkitt's-like (N=6), or other (N=2). Four of the CR pts have relapsed at 6, 9, 11, and 17 mos, and 25 CR pts remain in remission at a median follow-up of 27.5 mos (range: 4.8 – 45). Of 3 pts with PR or SD, 2 pts progressed at 3 and 11 mos, and 1 PR pt was lost to follow-up at 15 mos. Of 21 pts who have died, 3 had CR. Median PFS and OS were 8.0 and 12.5 mos, respectively, in double-hit pts (myc+ with t(14;18)) vs. median PFS and OS not yet reached in pts who were myc+ without t(14;18) (p=0.04 for PFS; p=0.05 for OS). Additional factors associated with shortened PFS in univariable analysis included IPI ≥3 (p=0.0001), age ≥ 60 (p=0.046), and presence of B-symptoms (p=0.025). Morphology (DLBCL vs. BCLU), therapy received, Ki-67, and presence of bulky disease ≥5cm were not significantly associated with PFS or OS. In multivariable analysis, CR was independently associated with increased PFS (p=0.0036) and OS (p=0.008; Figure 1B), while t(14;18), morphology, front-line therapy, IPI, bulky disease, age, or presence of B- symptoms were not independently associated with PFS or OS. While increased IPI (p=0.00034) and B-symptoms (p=0.04) were associated with a failure to achieve CR, morphology and therapy were not. Conclusion: While myc+ NHL, with or without t(14;18), has historically been associated with inferior PFS and OS, achievement of a CR with front-line therapy was indicative of a favorable PFS and OS vs. those who do not achieve CR. Additional evaluation of myc+ aggressive NHL is needed to characterize pre-treatment factors associated with achievement of CR and to further evaluate the association of CR to induction therapy with survival outcomes. Disclosures: No relevant conflicts of interest to declare.

Introduction: Standard first line therapy (LOT) for patients (pts) with large B-cell lymphoma (LBCL) involves chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) or a similar regimen, e.g. R-CHOP with the addition of etoposide (R-EPOCH). While most pts respond, 30-40% of pts relapse or fail to achieve remission with 1st LOT. For those pts, the goal of curative 2nd LOT is typically platinum-based salvage chemotherapy in preparation for autologous stem cell transplant (ASCT). However, many pts (50% or more) do not qualify for intensive therapy, either due to age or comorbidities, or because they do not respond to or cannot tolerate salvage chemotherapy. For those further treatment options are limited. Objectives: In a sample of U.S. LBCL pts 65 and older, who have progressed to 2nd LOT and are eligible for ASCT, to compare the patient characteristics, treatments, costs and overall survival between pts who received SCT with those who did not. Methods: This retrospective cohort study used 100% Medicare Fee-for-Service Parts A/B claims data and Part D Prescription Drug Event data to identify pts ≥ 65 years of age, newly diagnosed with LBCL in 2012-2017, and who had ≥ 6 months continuous enrollment pre-diagnosis (baseline) and ≥ 12 months post-diagnosis, or who died after initiation of 2nd LOT. All were treated with a CHOP-like regimen 1st LOT and progressed to 2nd LOT. Eligible pts who received a 2nd LOT with a SCT-preparative regimen per NCCN guidelines were stratified into the "ASCT-intended" cohort, and the remainder into the "ASCT-not-intended" cohort. The ASCT-intended group was further subset into those who received a SCT and those who did not (Non-SCT). These 2 subsets formed the primary comparison groups. Baseline characteristics were age, gender, race, dual eligibility status (i.e. Medicare plus Medicaid), and Charlson-Deyo Comorbidity Index (CCI). Measures of utilization during follow-up (from initiation of 2nd LOT to loss to follow-up) were hospitalizations, outpatient and emergency department (ED) visits, and post-acute care. Costs during follow-up reflected standardized, inflation-adjusted, all-cause paid amounts. Utilization and cost metrics were standardized to per-patient-per-month (PPPM). Overall survival (OS) was measured from the start of 2nd LOT until death, disenrollment or the end of the study period. Results: 4,758 pts met all inclusion criteria. 3,713 (78%) did not receive a SCT-preparative regimen after 1st LOT. 1,045 pts (22%) received a SCT-preparative regimen and constituted the ASCT-intended group. Of these, 244 (23.3%) received a SCT and 801 (76.7%) did not. The remainder of this report focuses on a comparison of the SCT and non-SCT cohorts. Baseline characteristics, treatments, utilization and cost are summarized in Table 1. Both groups were predominantly white, but SCT pts were, on average, 5 years younger, slightly more likely to be male, and had slightly lower mean CCI scores. 13.1% of non-SCT pts were dual eligible vs. 4.5% of SCT (all p &lt; .01 except Race). 93.9% of SCT procedures were autologous, and no pts had more than 1 SCT during follow-up. Non-SCT pts had higher all-cause utilization for all categories except for acute hospitalizations. The higher inpatient utilization for the SCT group may reflect the SCT procedure itself (94% of SCT were inpatient). A similar pattern was observed in the cost data, where Non-SCT pts incurred higher costs except for acute hospitalizations. Results for OS are summarized in Figure 1. Non-SCT pts had significantly lower rates of survival than SCT pts. 94.7% of SCT pts were still alive 6 months after initiation of 2nd LOT, whereas only 66.9% of non-SCT pts were. At two years post-2nd LOT, survival rates were 69.7% vs. 36.3%. Conclusions: In this study, only 23.3% of SCT-intended pts ultimately received it. The remaining 76.7% were SCT-intended but never received a transplant. Compared to the SCT pts, the non-SCT pts were older, had more comorbidities, had higher rates of healthcare utilization and costs post-2nd line therapy in all categories (except acute inpatient), and lower OS. 38.7% of non-SCT pts proceeded to additional lines of lymphoma-directed therapies beyond 2nd line, which may suggest that their clinicians felt that there was potential benefit to further treatment. These data suggest there may be unmet need for elderly pts with LBCL who are eligible for ASCT, but do not ultimately receive it. Disclosures Kilgore: Kite, A Gilead Company: Research Funding.

Abstract Introduction: Hemophagocytic lymphohistiocytosis (HLH) is a severe hyperinflammatory syndrome caused by excessive immune activation leading to a life-threatening pro-inflammatory cytokine storm. HLH is not an entity of its own, but a clinical syndrome triggered by various conditions like infections, malignancy or autoimmune disorders. HLH pathogenesis is complex and still not fully understood. Contributing factors include immunosuppression (chemotherapy, long-term immunosuppressive therapy), cytokine release from tumor cells, imbalance between infected and immune effector cells as well as genetic predisposition. Despite improved HLH-specific therapy (adapted components from the pediatric HLH-1994 protocol), prognosis is still poor among adult HLH patients. Due to the lack of data on adult HLH in Germany, a national multicenter registry (http://www.hlh-registry.org/) was initiated. Methods: Patients (pts) with proven or suspected HLH were registered by 35 institutions across Germany from August 2010 to July 2016. Both HLH-2004 diagnostic criteria and the HScore (www.saintantoine.aphp.fr/score/) were used to confirm HLH diagnosis. To characterize adult HLH patients, data referring to underlying disease, treatment, outcome, clinical manifestations and laboratory findings were recorded. Where available, patient samples were tested for mutations of the perforin gene PRF1 by standard Sanger sequencing. Results: A total of 125 pts (48 female) were enrolled in our registry, of whom 105 pts either fulfilled diagnostic criteria according to HLH-2004 diagnostic guidelines (n=96) or met at least 4 out of 8 criteria and reached HLH-probability of over 90 % in the HScore (n=9). Among these 105 pts, n=38 (36 %) were female and n=67 (64 %) male. Median age at diagnosis was 49 years (range 17 - 81). Trigger diseases were in line with the literature, with infections (n=34) and malignancy (n=40) being most frequent (Table 1). Patients show a wide spectrum of underlying conditions, i.e. allogeneic stem cell transplantation (alloSCT) or HLH-mimicking diseases due to cytokine release in response to blinatumomab therapy. Late onset hereditary HLH was found in 3 pts (XLP-1 and -2 respectively in EBV-coinfected pts, one pt with perforin mutation - see below). 22 of 105 patients (21 %) were tested for PRF1 mutations. A compound heterozygous PRF1 A91V/Q405X mutation was identified in one pt presenting with NK/T-cell lymphoma. Heterozygous PRF1 A91V mutations were found in 2 pts with B-cell lymphoma and HLH following alloSCT respectively, in one case with available buccal swab DNA to prove germline origin of the mutation. Table 2 summarizes clinical and laboratory findings in the cohort. A median ferritin value of 32,000 µg/L underlines the importance to evaluate pts with highly elevated ferritin with respect to potential HLH diagnosis. Apart from fever and splenomegaly, clinical presentation frequently comprised hepatomegaly, liver failure, hyperbilirubinemia, renal failure, lung involvement like ARDS, or bleeding. Treatment included steroids in the vast majority of pts (n=89), often combined with i.v. immunoglobulins (n=47) and etoposide (n=49). After a median follow up time of 164 days, 48/97 pts (49.5 %) were alive, 8 pts were lost to follow up. Survival analysis revealed median overall survival of 454 days (Figure 1a). Comparing malignancy-associated HLH and HLH after alloSCT with infection- and autoimmune-associated HLH or HLH due to unknown triggers, survival was significantly poorer in the malignancy/alloSCT group (Figure 1b). Conclusions: HLH trigger conditions in adult patients in Germany are in accordance with published case series. Outcome in adult HLH is still poor, with malignancy-associated and HLH after alloSCT showing the worst prognosis. Diagnostic vigilance and early treatment is a prerequisite for improving outcome of adult HLH. In particular, high ferritin values should raise suspicion of HLH.

End Of Treatment

Introduction: 2-[18F] fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) remains the standard of care for baseline and end of treatment scans for aggressive non-Hodgkin lymphomas (NHLs). However, the role of interim FDG-PET remains not as well defined across aggressive NHLs, especially in the era of high-intensity chemoimmunotherapy. Interim FDG-PET (iPET) can serve as an early prognostic tool, and prior studies evaluating the utility of iPET-guided treatment strategies primarily focused on diffuse large B-cell lymphomas (DLBCL) and frontline R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone). Classification criteria systems assessing response also differ between studies with no clear consensus between use of Deauville criteria (DC), International Harmonization Project (IHP), and the ΔSUVmax method. Methods: This study evaluates our institutional experience with iPET during treatment with DA-EPOCH ± R (dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin with or without Rituximab) in aggressive NHLs. We retrospectively evaluated 70 patients at Moffitt Cancer Center who started on DA-EPOCH ± R between 1/1/2014 to 12/31/2018 for aggressive NHLs. Response on interim and end-of-treatment (EOT) scans were graded per DC, IHP, and ΔSUVmax methods, and progression free survival (PFS) probability estimates were calculated with chi-square testing and Kaplan Meier method. PFS outcomes were compared between interim negative and positive scans based on each scoring method. Outcomes were also compared between groups based on interim versus EOT positive or negative scans. Results: We identified 70 patients with aggressive NHLs who received DA-EPOCH ± R at our institute. The most common diagnoses were DLBCL (61%) followed by Burkitt's lymphoma (10%), primary mediastinal B-cell lymphoma (9%), plasmablastic lymphoma (7%), gray zone lymphoma (6%), primary cutaneous large B-cell lymphoma (1%), primary effusion lymphoma (1%), and other high-grade NHL not otherwise specified (3%). Of the 43 patients with DLBCL, 21/43 (49%) had double hit lymphoma (DHL) while 7/43 (16%) had triple hit lymphoma (THL), and 3/43 (7%) had MYC-rearranged DLBCL while 2/43 (5%) had double expressor DLBCL. Thirty nine out of 70 (56%) were female, and median age at diagnosis was 58.39 years (range 22.99 - 86.86 years). Most patients had stage IV disease (49/70, 70%), and 43/70 (61%) had more than one extranodal site while 45/70 (64%) had IPI score ≥ 3. Forty-six out of 70 (66%) received central nervous system prophylaxis, most with intrathecal chemotherapy (44/70, 63%). Fifty-five out of 70 (79%) had iPET available while 6/70 (9%) had interim computerized tomography (CT) scans. Fifty-six out of 70 (80%) had EOT PET, and 4/70 (6%) had EOT CT scans. Sustained complete remission occurred in 46/70 (66%) after frontline DA-EPOCH ± R (CR1), and 12/70 (17%) were primary refractory while 5/70 (7%) had relapse after CR1. Four of 70 (6%) died before cycle 3, and 3/70 (4%) did not have long-term follow-up due to transition of care elsewhere. Median follow-up was 15.29 months (range 0.85 - 60.09 months). There was significantly better PFS observed if iPET showed DC 1-3 compared to DC 4-5 (Χ2=5.707, p=0.0169), and PFS was better if iPET was negative by IHP criteria (Χ2=4.254, p=0.0392) or ΔSUVmax method (Χ2=6.411, p=0.0113). Comparing iPET to EOT PET, there was significantly better PFS if iPET was negative with EOT PET negative (iPET-/EOT-) compared to iPET positive with EOT negative (iPET+/EOT-), and iPET+/EOT+ and iPET-/EOT+ had worse PFS after iPET-/EOT- and iPET+/EOT- respectively. This pattern in iPET/EOT PFS probability remained consistent when comparing DC (Χ2=30.041, p<0.0001), IHP (Χ2=49.078, p<0.0001), and ΔSUVmax method (Χ2=9.126, p=0.0104). These findings fit clinical expectations with positive EOT scans indicating primary refractory disease. There was no significant difference in PFS when comparing DLBCL versus non-DLBCL (Χ2=3.461, p=0.0628) or DHL/THL versus non-DHL/THL diagnoses (Χ2=2.850, p=0.0914). Conclusion: Our findings indicate a prognostic role of iPET during treatment with DA-EPOCH ± R for aggressive NHLs. Significant differences in PFS were seen when graded by DC, IHP, and ΔSUVmax methods used in prior studies and when comparing interim versus EOT response. Larger studies are needed to confirm these findings. Disclosures Bello: Celgene: Speakers Bureau.

Abstract From 1985 to 2006, 71 patients with primary mediastinal large B-cell lymphoma receiving induction doxorubicine-based chemotherapy followed by ASCT as front-line therapy were registered in the GEL-TAMO (Spanish Group for Lymphoma and Autologous Transplantation). Median age was 28 years, 56% of patients were female, 40% presented with an ECOG ≥ 2; B-symptoms at diagnosis were present in 25% of the patients. Most patients presented with high-risk clinical features: bulky tumours defined as ≥10 cms of diameter were observed in most patients (87%), high LDH in 72% and, as previously reported (Rodriguez et al, Ann Oncol, 1994), β2m was elevated only in 7% of the cases. Forty-seven percent of patients presented 2–3 risk factors of the a-IPI. At transplant, thirty-five patients (49%) in first complete remission (CR), 23 (33%) in partial response and 13 patients (18%) failing the first induction therapy were transplanted, respectively. Conditioning regimens were BEAM or BEAC in 90% of the patients. 39 patients received Radiotherapy: 19 prior and 20 after the transplant. Most patients (91%) received peripheral stem cells. Only a patient failed to engraft after the transplant. After the transplant 73% of the patients achieved a CR and 17 patients were refractory. With a median follow-up from transplantation of 46,5 months the OS, PFS and DFS are 68%, 59% and 81% respectively. Progression of the disease was the main cause of death (78%). A patient died of a second neoplasia and 3 patients died of sepsis. There were no deaths related to transplant toxicity. By multivariate survival analysis both status of the disease at transplant (CR vs PR vs failure) and the Tumor score (Rodriguez et al, Ann Oncol,1992 ) were the only independent variables associated with the OS and PFS, respectively. In conclusion our experience, with a prolonged follow-up, shows that patients with primary mediastinal large B-cell lymphoma presenting at diagnosis with high-risk features have an encouraging survival and PFS with front-line ASCT. However, patients who received the transplant having failed the induction regimen have a very poor prognosis and should be tested with another innovative approach.

Abstract Abstract 2812 Introduction: Nodular lymphocyte predominant Hodgkin's lymphoma (NLPHL) constitutes 5% of Hodgkin's lymphoma (HL) diagnoses. Recently gene expression profiling has shown significant overlap between NLPHL, T-cell-rich B cell lymphoma (TCRBCL), and classical HL (Brune, V et al, J Exp Med, 2008). NLPHL patients also have an approximate 7% risk of transformation at 10 years to diffuse large B-cell lymphoma (DLBCL) and TCRBCL (Al-Mansour, M et al, JCO, 2010). Data from multiple groups (Nogova, L et al, Ann Onc, 2005, Chen, RC et al, JCO, 2010, Wirth, A et al, Cancer, 2005) support extended progression-free survivals (PFS) for stage IA/IIA patients treated with radiation alone. While chemotherapy is generally recommended for patients with stage IB/IIB or III/IV disease, there is lack of guidelines on whether classical HL-directed regimens, such as ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine), or B-cell lymphoma-directed regimens, such as R-CHOP (rituximab, cychlophosphamide, doxorubicin, vincristine, prednisone) should be used. Given the similarities between NLPHL and indolent CD20+ B-cell non-Hodgkin's lymphoma (NHL), our group started using the R-CHOP regimen for patients with NLPHL requiring systemic therapy. In order to examine the potential efficacy of this approach, we conducted a retrospective analysis of treatment outcomes in patients who received R-CHOP versus other regimens treated at UT MDACC from 1995 to 2010. Results: 83 patients were referred. 6 patients were found to have NLPHL with transformation to DLBCL or TCRBCL. 3 had alternative diagnoses. 11 lacked full immunophenotyping to confirm diagnosis. 63 patients had confirmed diagnoses of NLPHL (39 stage I/II and 24 stage III/IV). 52 NLPHL patients were evaluable (10 did not complete full treatment planning or were lost to follow-up and 1 is currently completing therapy). 7 patients had extranodal disease (thyroid, breast, lung, liver, bone marrow/cortex) and 8 had spleen involvement. Overall their median age at diagnosis was 40, male:female ratio was 2.5, and median follow-up is 46 months (range 8–149 months). 6 patients had relapse of NLPHL, 2 patients had transformation at a median of 39 months (1 to DLBCL, 1 to TCRBCL), 4 patients died (1 from acute myelogenous leukemia with deletion 7, 1 from DLBCL, 2 from unrelated causes while in remission), and 2 patients underwent autologous stem cell transplant (1 for relapsed NLPHL in 3rd complete remission and 1 for transformation to TCRBCL). Therapies for stage I/II NLPHL included: surgical excision alone (2 patients with stage IA disease declined radiation treatment), subtotal nodal irradiation (STNI), mantle field radiation, involved field radiation (IFRT), rituximab (R) alone and plus IFRT, ABVD plus STNI, R-ABVD, COPP (cyclophosphamide, vincristine, procarbazine, prednisone) plus IFRT, and R-CHOP alone and plus IFRT. Therapies for stage III/IV included: mantle field radiation (1 patient who declined chemotherapy), NOVP (mitoxantrone, vincristine, vinblastine, prednisone) plus mantle field radiation, ABVD, R-ABVD, R-CHOP alone and plus IFRT. A total of 15 patients received R-CHOP alone (4 stage I/II, 11 stage III/IV) and 5 patients received R-CHOP plus IFRT (4 stage I/II, 1 stage III/IV). Response to R-CHOP as assessed by CT scan criteria was 100% overall response rate (ORR) with 90% complete remissions (CR). No R-CHOP patients have had relapses or transformation with a median follow-up of 42 months (range 8–111 months). One patient treated with R-CHOP died of unrelated causes while in remission. However, with other therapies 19% have relapsed after median remissions of 38 months (range 4 to 72 months). R-CHOP when compared to other treatments has a trend towards improved PFS (Figures 1, 2, and 3). Survival rates for NLPHL patients at 5 years with 95% confidence intervals are: R-CHOP: PFS 0.95 (0.86, 1), OS (overall survival) 0.95 (0.86, 1) and other therapies: PFS 0.71 (0.55, 0.92), OS 0.91 (0.8, 1). Conclusions: Our data demonstrates that RCHOP is an effective regimen for the treatment of patients with NLPHL. A prospective evaluation of R-CHOP as a front-line treatment of NLPHL is under consideration.

Off Label Use: Given the CD20 positivity of nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) rituximab has been evaluated previously for relapsed NLPHL and was shown to be efficacious. Rituximab however is not FDA approved for NLPHL. This is a retrospective study that evaluates the use of R-CHOP and other therapies for NLPHL. Current NCCN guidelines support consideration of R-CHOP for NLPHL treatment, and given the rarity of the disease there is no one defined preferred chemotherapy regimen. This information will be disclosed to the audience. Fayad:Genentech: Research Funding. Rodriguez:Genentech: Research Funding.

Abstract Abstract 2608 Background: Combined treatment with a tyrosine kinase inhibitor (TKI) and ALL-type induction and consolidation chemotherapy followed by allogeneic SCT is standard front-line therapy for younger patients with Ph+ALL, but the value of adding intensive chemotherapy to a TKI in elderly patients is controversial. More than 90% of elderly patients achieve a complete remission, irrespective of the type of TKI-based induction, but relapse is the major cause of treatment failure. In a previously reported randomized trial examining imatinib combined with intensive induction and consolidation chemotherapy for Ph+ALL in elderly patients (n=55), the probability of overall survival (OS) after 24 months was 42% ± 8% (Ottmann OG et al., Cancer. 2007; 109:2068-76). To date, very little published data on long-term outcome of elderly patients with Ph+ALL are available. Aims: We conducted the present analysis to determine whether subsets of patients derive long-term benefit from combined imatinib plus intensive chemoptherapy, examine the characteristics of long-term survivors, determine whether such patients can be identified by assessment of MRD, and obtain preliminary results on the feasibility and efficacy of SCT in this population of elderly patient. Study design and patients demographics: Our current analysis includes a total of 121 patients (119 ALL, 2 CML in lymphoid blast crisis), with a median age of 66 years (range 54–80). Fifty-five patients were enrolled in a previously reported randomized clinical trial comparing single-agent imatinib and chemotherapy as induction therapy, followed by up to 6 cycles of consolidation chemotherapy; a further 67 patients were subsequently treated according to this protocol as per recommendation by the GMALL Study Group. Results: The overall CR rate was 88%, median time to progression was 14.5 months (range 0.5–102) and OS was 18.6 months (range 0.5–102), respectively. Probabilities of remission duration, survival and TTP at 5 years were 19%, 22% and 19%, respectively. The type of initial induction therapy had no significant impact on OS and DFS. Of 113 pts, who were evaluable for comorbities, pulmonary disease was the only comorbidity associated with inferior outcome (median OS 13 months vs. 20 months, univariate analysis p=0.02). Allogeneic SCT was performed in CR1 in 12 patients and as salvage therapy in another 7 patients. Median age of these 19 patients was 62y (range 54–69). The time from diagnosis to SCT in CR1 was 4.6 months (2.9 mo – 16.8 mo) and from relapse to SCT in >CR1 3 months (2.1 mo – 6.1 mo). The 5yr OS in patients transplanted in CR1 vs. non-transplanted patients was superior (48% vs 22%). Remarkably, OS of the 7 patients transplanted beyond CR1 as part of salvage therapy was 43% after 4.5 years. With a median follow-up of 21.6 months (range 3.3– 54) after SCT, 8 patients are in ongoing CR with a median OS of 51.8 months from initial diagnosis (range 35 – 66), 5 pts. died in CR, 6 pts. relapsed. Conclusions: The combination of imatinib with intensive chemotherapy is feasible in elderly patients, but long-term survival is poor primarily due to high relapse rate. Allogeneic SCT in CR1 is superior to conventional therapy and should be considered as front-line therapy in this elderly patient population. The encouraging results of allogeneic SCT performed beyond CR1 suggest that SCT should be considered as definite postremission therapy in a larger proportion of elderly patients than is current practice.

Abstract Background Bendamustine in combination with rituximab (BR) has shown to be similar, if not superior, in efficacy with more favorable side-effect profiles compared to R-CHOP (rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine, and prednisone) for front-line treatment of indolent B-cell lymphoma. In addition, bendamustine 120 mg/m2 in combination with rituximab 375 mg/m2 was associated with high response rates and acceptable toxicity even in older patients with relapsed or refractory aggressive B-cell lymphoma. Clinical evaluation of BR is warranted in the front-line setting for DLBCL patients not eligible for anthracyclines or very elderly, for whom the standard therapy has not been established. Methods In this single-arm phase II study, patients with ≥65 years of age who were deemed poor candidates for R-CHOP therapy at the discretion of the treating physician were enrolled through the UNC Cancer Network to determine the efficacy and safety of BR in previously untreated stage II-IV DLBCL (ClinicalTrials.gov #NCT01234467). Patients received bendamustine at a dose of 120 mg/m2 daily on days 1 and 2 of each 21-day cycle along with rituximab on day 1 for up to 8 cycles of therapy. Patients with ECOG score of 3 at baseline were allowed to receive bendamustine at a dose of 90 mg/m2 daily, and the dose would increase to 120 mg/m2 daily if their ECOG score improved to ≤ 2 after 3 cycles of BR. Pre-phase steroid therapy with prednisone 100 mg daily for five days was permitted prior to the initiation of BR in patients with poor functional status at the initial presentation. Results Twenty three patients were enrolled with the majority (83%) having stage III or IV disease at baseline. The median age was 80 years (range 65 – 89), and 78% of patients had IPI score of ≥3. More than half the patients (52%) presented with poor functional status with ECOG score of ≥2 prior to therapy, including six patients with ECOG score of 3. The overall response rate was 93% with a complete response rate of 60% for 15 evaluable patients. The median time to progression (TTP) was 7.4 months. The median survival was 9.9 months (95% CI of 3.6 – 10.9) for all patients, but for patients with ECOG score of ≥2, the median survival was 3.6 months (1.4 – 6.0). Grade 3/4 AEs observed in > 10% of patients were anemia (27%), neutropenia (18%), lymphopenia (68%), thrombocytopenia (18%), and fatigue (14%). Four grade 5 treatment-related AEs, including two cases of pneumonia and two cases of anorexia, were reported. Four deaths were directly related to disease progression during or after treatment. Six patients died of other causes, including cerebral vascular accidents, congestive heart failure, and hip fracture, which were felt to be related to the patients' underlying comorbidities. Overall survival at 12 months was 25% (8.2 – 46.9). Conclusions Combination therapy with BR demonstrates high response rates in older patients who were deemed poor candidates for the standard R-CHOP therapy for treatment of previously untreated DLBCL. However, the survival rates were not considered promising in this older frail patient population. BR, especially with a high dose of bendamustine, should be used with great caution in future clinical trials involving older DLBCL patients with poor functional status.

Abstract Background Double-hit (DHIT) lymphoma is a heterogeneous group of non-Hodgkin lymphomas characterized by concurrent translocations involving MYC and BCL2 and typified by aggressive behavior and poor prognosis with only rare long-term survivors. There is no established treatment for DHIT lymphoma. Since 2003, the British Columbia Cancer Agency (BCCA) has adopted the use of intensive chemotherapy CODOX-M/IVAC combined with rituximab (R) followed by high-dose chemotherapy and hematopoietic cell transplantation (HSCT) as definitive treatment for DHIT lymphoma. In younger patients, an ablative matched sibling donor allotransplant (AlloSCT) is preferred over an autotransplant (AutoSCT). For all patients over the age of 60 years only AutoSCT is offered. Total Body Irradiation (TBI) is used as a part of the conditioning regimen for patients younger than 60 years of age. Here we report our provincial experience with this strategy, focusing on the ability to deliver this treatment and survival outcomes. Methods The Leukemia/BMT Program of British Columbia database and the BCCA Lymphoid Cancer Database were searched to identify all patients diagnosed with non-Hodgkin lymphomas with concurrent translocation of MYC and BCL2 (DHIT lymphoma) diagnosed between January 2003-September 2012. Results 27 cases of DHIT lymphoma were identified with the following characteristics: median age at diagnosis was 55.8 years (range 35.5-70.9 years); 19 (70%) were male; 26 (96%) patients had stage 3/4 disease; 16 (59%) had bone marrow involvement. All cases were HIV negative. Histological diagnosis based on the WHO 2008 classification were: diffuse large B-cell lymphoma (DLBCL) n=8 (30%); B-cell lymphoma, unclassifiable, with features intermediate between DLBCL and Burkitt lymphoma (BCL-U) n=17 (63%); B-cell acute lymphoblastic lymphoma (ALL) n=1; high-grade B-cell lymphoma, not otherwise specified (NOS) n=1. 13 cases (48%) were transformed from an underlying indolent B-cell lymphoma (12 follicular lymphoma, 1 low-grade B-cell lymphoma NOS). CODOX-M/IVAC + R was administered in 20 patients (74%). 7 patients received alternative chemotherapy regimen (5 R-CHOP, 1 R-CVP, 1 R-ICE) due to patient and/or physician preference. 14 patients (52%) underwent HSCT (7 AutoSCT, 7 AlloSCT), including 11 patients treated CODOX-M/IVAC + R pre-transplant, and 3 patients who received other therapy. 13 patients did not undergo HSCT: primary refractory disease n=7; patient preference n=2; deconditioning n=1; age > 65 and poor performance status n=3. The clinical status at time of transplantation was CR in 5 patients (19%), PR in 8 (30%), progressive disease in 1 (4%). The conditioning regimens included: cyclophosphamide/TBI n=6, VP-16/cyclophosphamide/TBI n=4, BEAM n=3, busulfan/cyclophosphamide n=1. At last follow-up, 15 (56%) patients have died, 14 from disease progression and 1 from complications of AlloSCT. 10 (37%) patients are alive and in remission and 2 patients are alive but have relapsed. 8 of 14 HSCT recipients (6 AutoSCT, 2 AlloSCT) remain alive and free of disease compared with 2 of 13 patients who did not receive HSCT; both disease free survivors received CODOX-M/IVAC + R. Median follow-up for living patients was 31 months (range 6.5-67.3 months). 2-year EFS and OS from the diagnosis of all DHIT lymphoma patients were 35% (95% CI 16%-54%) and 45% (95% CI 20%-65%), respectively. For patients who received CODOX-M/IVAC + R, the 2-year EFS was 37%. For patients who received CODOX-M/IVAC + R followed by SCT, the 2-year EFS was 43%. Patients with BCLU/ALL/High-grade lymphoma NOS had a 2-year EFS of 27% and patients with DLBL had a 2 –year EFS of 50%. Conclusion Patients with DHIT lymphoma treated with CODOX-M/IVAC + R followed by SCT can have durable remissions. Regardless, progression during initial therapy prior to SCT remains a significant problem. Patients with DLBCL histology may have a more favorable outcome than those with BCLU.

Abstract Introduction Among patients with aggressive B-NHL who fail RCHOP, about half respond to standard salvage regimens and may proceed to curative-intent, transplant-based therapy. However, whether pts failing more intensive regimens such as dose-adjusted, infusional EPOCH benefit from standard salvage regimens is unclear. We hypothesized that such patients comprise a higher-risk cohort, facing inferior response rates and outcomes using standard salvage regimens. We undertook a collaborative study to assess response rates and survival among pts failing EPOCH for aggressive B-NHL, to inform patient management and design of clinical trials in this setting. Methods Pharmacy records and institutional databases were queried, identifying pts receiving EPOCH over the last 10 years at the University of Washington/SCCA and the Cleveland Clinic Foundation, for combined analysis. Under IRB approval, patient characteristics, histology, outcome with EPOCH, time to EPOCH failure, response to salvage, and overall survival were analyzed. Diffuse large B cell lymphoma (DLBCL), primary mediastinal B-cell lymphoma, B-cell-lymphoma unclassifiable, HIV-associated B cell lymphoma, and transformed B cell non-Hodgkin lymphoma were included. Pts receiving <2 cycles EPOCH, or who had inadequate follow-up (<3 months), were excluded. Failure of EPOCH was defined as failure to respond or progression during therapy, need for initiation of salvage therapy, or death during therapy of any cause. Adverse events or treatment change due to toxicity were not included in the definition of failure. JMP 11 was used to generate kaplan-meier survival estimates. Results 124 pts with aggressive B-NHL receiving EPOCH were identified. 54 had not relapsed, and among 70 remaining da-EPOCH failures, 37 met the above inclusion criteria. Median age was 55. 27% were female, and 23 received EPOCH as first-line therapy. All but 3 received rituximab with EPOCH. Histologies were primarily DLBCL in 22/37 (60%) and BCL-U in 12/37 (32%) carrying a MYC translocation; most of these harbored additional translocations in BCL2 and/or BCL6 (10/12). However, data regarding MYC rearrangement was not available for all pts. 2 had HIV-associated B-NHL and 3 had PMBCL. With 18 months follow up, the median time to EPOCH failure was 5 months. Only 3 EPOCH failures occurred late (>12 months). Median OS from the date of EPOCH failure was 10 months (Figure 1). Those receiving EPOCH as first-line therapy (23) had a median OS of 14 months from EPOCH failure, as opposed to 4 months for those receiving EPOCH as salvage therapy (log-rank p=.01). Salvage chemotherapy regimens after EPOCH were diverse, and generally ineffective; 6/28 (21%) regimens produced a response (Table 1). Among patients failing EPOCH within a year, platinum-containing salvage (RICE/RDHAP) was effective in only 2/13 patients (15%). 9 patients did not receive any salvage, most of whom died or proceeded to palliative measures and/or hospice care. Conclusions A relatively low overall response rate (21%) was observed in this retrospective analysis of patients failing EPOCH. Analogous to early RCHOP failure in the CORAL study, those failing EPOCH within a year may face inferior outcomes with platinum-based salvage therapy. While combined from two institutions, our data represent a modest sample size and require confirmation. If verified, examination of mechanisms of resistance to EPOCH, and selecting EPOCH failures for clinical trials of novel targeted therapies and transplant-based approaches, may prove critical.
