Abstract Introduction Although several previous studies addressed the role of radiation in treating localized diffuse large B-cell lymphoma (DLBCL), chemotherapy alone has shown promising efficacy with the emergence of Rituximab. Thus, we evaluated the clinical efficacy outcomes and failure patterns of patients with localized DLBCL according to two different treatment strategies, either 6 or more cycles of R-CHOP chemotherapy alone or 3 or 4 cycles of R-CHOP followed by involved field radiotherapy (IFRT). Methods A prospectively collected database from 21 tertiary centers participating the Consortium for Improving Survival of Lymphoma (CISL), built up for PROCESS study (NCT01202448) for secondary central nervous system involvement in DLBCL, was recruited for current study in addition to the Asan Medical Center (AMC) Lymphoma Registry. CISL database and AMC lymphoma registry consisted of data from patients with newly diagnosed DLBCL between August 2010 and August 2012, and between February 2004 and February 2012, respectively. Inclusion criteria were localized (stage I or II), non-bulky (<10cm in longest diameter) DLBCL treated with R-CHOP as 1st line chemotherapy, and patients either who received 6 or more cycles of R-CHOP chemotherapy only (R-CHOP alone group) or received 3 or 4 cycles of R-CHOP chemotherapy followed by IFRT (R-CHOP plus RT group). Comparisons of clinicopathologic parameters, clinical outcomes and the patterns of relapse were performed between two groups. The types of relapse were classified as either locoregional or distant, according to whether it involves any separate region from primary sites. Efficacy outcomes included complete response (CR) rate, 2-year overall survival (OS) rate, and 2-year event-free survival (EFS) rate. Results A total of 357 patients (CISL prospective cohort: 161 patients, AMC registry: 196 patients) were eligible for the analyses. Two hundred ninety nine patients (83.5%) received 6 or more cycles of R-CHOP chemotherapy alone, and 58 patients (16.2%) underwent 3 or 4 cycles of R-CHOP followed by IFRT. Median age was 54 years (range, 16-87). During the median follow-up of 24 months (range, 4-116 months), 35 patients (9.8%) experienced relapse, and 22 patients (6.1%) died. Two-year OS and EFS rate was 94.7% and 89.9%, respectively, and 345 out of 357 patients (96.6%) achieved CR. Comparing R-CHOP alone to R-CHOP plus RT group, there was no significant difference in clinicopathologic parameters. R-CHOP alone could achieve significantly higher CR rate of 97.7 % than 91.4% of R-CHOP plus RT group (p = 0.030). Two-year OS and EFS were significantly longer in R-CHOP alone group than R-CHOP plus RT group (96.1 vs 89.9 %, p = 0.029 and 91.7% vs 81.8%, p= 0.028) (Figure 1). Relapse rate was significantly lower in R-CHOP alone group compared with R-CHOP plus RT group than group (7.4% vs 22.4%, p=0.001), and distant relapses were also significantly lower (15.5% vs 2.7%, p<0.001). In addition, even only in relapsed patients, R-CHOP alone group showed lower incidence of distant relapses with marginal statistical significance (36.4% vs 69.2 %, p=0.062) (Table 1). Conclusion In our cohort, R-CHOP alone for six to eight cycles without IFRT could achieve significantly higher 2-year OS and EFS rate as well as CR compared with R-CHOP plus RT group. In addition, the rate of relapse and systemic failure were significantly lower in R-CHOP alone group, which altogether warrant further validation in prospective trial. Table 1.

18536 Background: R-CHOP is regarded as the best available treatment for untreated patients with aggressive and indolent B- NHL. Methods: 184 previously untreated patients with DLCL were included in retrospective study: 92 patients were treated by CHOP, 92 patients were treated by CHOP plus rituximab ( R-CHOP ). Age of patients ranged 16–87 years (median 50 years). The median follow- up was 18 months. Compared groups were balanced in all parameters. The advanced stage of disease (III-IV) at diagnosis had 66% patients treated with CHOP and 67,5 % patients treated with R-CHOP. =2 extranodal zones were initially revealed at 35% in CHOP group vs 47% in R- CHOP group. PS of 25 % patients in R-CHOP group and 30% patients in CHOP group was regarded as appropriate 3–4 degrees on ECOG. Increased LDH level was marked at 60% in CHOP-group vs 54% in R-CHOP. 29% patients in R-CHOP group and 21% patients in CHOP group had B-symptoms at diagnosis; bulky disease took place in 53% cases in R-CHOP group and 62% cases in CHOP. High IPI score had 47 % patients in CHOP-group vs 48 % in R-CHOP. Results: Complete response was achieved in 74% of the patients treated with R- CHOP, as compared to 56% of those treated with CHOP alone (p<0,05). Disease progression during treatment was reported in 25% of patients in CHOP group and 18,5% in R-CHOP group. Median overall survival in patients treated with R-CHOP was NS, in patients treated with CHOP alone was 16 months. With a median follow-up of 18 months, 29 (31,5%) events (progression - 18,5%, relapse - 10%, death - 3% ) were observed in the R-CHOP group and 48 (52%) events ( progression - 25%, relapse - 20%, death - 7%) in the CHOP group (p<0,05). Median event-free survival and relapse-free survival in the CHOP group was 12 months, in R-CHOP group NS. Toxicity was equivalent in both groups. Conclusions: We have established better direct efficiency and outcome of R-CHOP in any age of pts. No significant financial relationships to disclose.

Abstract Abstract 4894 Introduction Diffuse large B-cell lymphoma (DLBL) is the commonest type of lymphoma worldwide. The condition is the same in Hong Kong and it accounts for about 30–40% of lymphoma cases. CHOP (cyclophosphamide, doxorubicin, vincristine and prednisolone) was used for treatment of DLBL for many years. Rituximab, a chimeric anti-CD20 monoclonal antibody was used for the treatment of DLBL for about 10 years. Previous studies have shown the better efficacy of rituximab plus CHOP over CHOP alone, including the remission rate, overall and event-free survival. No previous study compared the efficacy of rituximab plus CHOP with CHOP alone in Hong Kong Chinese. We conducted a study to compare the outcomes of CHOP chemotherapy alone with rituximab plus CHOP in a local hospital in Hong Kong. Method It was a retrospective study from January 1999 to December 2009. Hong Kong Chinese patients with newly diagnosed diffuse large B-cell lymphoma were recruited in the study. They were divided into two groups. One group of patients was given CHOP chemotherapy and the other group was given rituximab plus CHOP. The remission rate, overall survival and event-free survival were compared in the two groups. Results 62 patients were recruited in the study. Twenty-nine patients with median age of 55 (range 23–77) were given CHOP chemotherapy alone. Thirty-two patients with a median age of 53 (range 20–75) were given rituximab plus CHOP. The baseline characteristics were similar in both groups. There were 41% of male patients in each group. IPI (international prognostic index) score as well as the proportion of patients at stage III and IV disease were similar in both groups. The complete remission rate was 38% in CHOP alone group and 78% in rituximab plus CHOP group (p=0.002, Fisher's exact test). The 3-year overall survival rate was 47% in CHOP group and 74% in rituximab plus CHOP group (p=0.043). The 3-year event-free survival was also better in the rituximab plus CHOP group (p=0.026). 19 events (including relapse, progression and death) were observed in the CHOP alone group and 8 events were observed in the rituximab plus chemotherapy group. The side effects profile was similar in both groups and the rate of infection is comparable in both arms. Conclusion This study has shown that the use of rituximab plus CHOP was better than CHOP alone in Hong Kong Chinese patients with newly diagnosed diffuse large B-cell lymphoma. The complete remission rate, overall survival and event-free survival were significantly higher in the rituximab plus chemotherapy group. Disclosures: No relevant conflicts of interest to declare.

Abstract Introduction Despite the advances in Diffuse Large B-Cell Lymphoma (DLBCL) treatment, there is a lack of uniformity regarding survival among the entire patient population. This study investigates several individual-level markers of socioeconomic and clinical status in relation to DLBCL survival. Methods This is a retrospective cohort study that utilizes a study population that was derived from the Moffitt Cancer Center Total Cancer Care protocol, a database that contains clinical, biological, and demographic information for over 73,000 patients as well as molecular and cytogenetic information on over 36,000 tumors. The database included 440 persons who were diagnosed with Diffuse Large B-Cell Lymphoma between 1998 and 2012. Of these persons, 274 met the eligibility criteria. A descriptive analysis was first conducted on all variables in the study and was then stratified by insurance status. A forward step-wise Cox proportional hazard regression was performed to calculate adjusted hazard ratios (HR) and their 95% confidence intervals for the association between insurance status and relapse, progression, or death utilizing SAS 9.3 (SAS Institute, Inc., Cary, NC). The Kaplan-Meier method was used to generate survival curves for each insurance group and compared according to the log-rank test. This was done in order to examine any differences in median survival time (in months) between the two groups. Results In terms of both overall survival and event-free survival, race was a significant prognostic factor in this study with non-Caucasian subjects being more likely to experience mortality (HR 2.33; 95% CI, 1.39 - 3.88). Subjects who presented with b-symptoms (fevers, unintentional weight loss >10%, and night sweats) at the time of diagnosis were significantly more likely to experience mortality (HR 2.48; 95% CI, 1.67 - 3.67) than those who were without them. Both stage and nodal status of a subject’s disease at the time of diagnosis were significantly associated with the outcome as subject’s with advanced stage disease (HR 3.89; 95% CI, 2.25 - 6.76) and extra nodal disease (HR 1.58; 95% CI, 1.04 - 2.39) had a higher risk of death. For overall survival, subjects in the privately-insured group experienced a significant difference in overall survival time (Log-Rank p=0.04) compared to those subjects with government-subsidized insurance (Figure 1). There was also a statistically significant difference in event-free survival between the two insurance groups (Log-Rank p=0.05) (Figure 2). Notably, age was not a significant covariate for OS or EFS, suggesting that the government-subsidized group was not biased by an increased proportion of elderly Medicare enrolled patients. Discussion In this retrospective cohort study, we observed that event-free survival time among subjects with private insurance were significantly improved from those subjects with government-subsidized insurance and overall survival time among subjects with private insurance were significantly improved from those subjects with government-subsidized insurance. We determined that after adjustment for demographic and clinical covariates, the covariates race, presentation of b-symptoms at the time of diagnosis, stage at the time of diagnosis, and nodal status of a subject’s disease were all significant prognostic factors in both overall and event-free survival.

Purpose We compared the efficacy of ofatumumab (O) versus rituximab (R) in combination with cisplatin, cytarabine, and dexamethasone (DHAP) salvage treatment, followed by autologous stem-cell transplantation (ASCT) in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL). Patients and Methods Patients with CD20+ DLBCL age ≥ 18 years who had experienced their first relapse or who were refractory to first-line R-CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone)–like treatment were randomly assigned between three cycles of R-DHAP or O-DHAP. Either O 1,000 mg or R 375 mg/m2 was administered for a total of four infusions (days 1 and 8 of cycle 1; day 1 of cycles 2 and 3 of DHAP). Patients who experienced a response after two cycles of treatment received the third cycle, followed by high-dose therapy and ASCT. Primary end point was progression-free survival (PFS), with failure to achieve a response after cycle 2 included as an event. Results Between March 2010 and December 2013, 447 patients were randomly assigned. Median age was 57 years (range, 18 to 83 years); 17% were age ≥ 65 years; 63% had stage III and IV disease; 71% did not achieve complete response (CR) or experience response for < 1 year on first-line R-CHOP. Response rate for O-DHAP was 38% (CR, 15%) versus 42% (CR, 22%) for R-DHAP. ASCT on protocol was completed by 74 patients (33%) in the O arm and 83 patients (37%) in the R arm. PFS, event-free survival, and overall survival were not significantly different between O-DHAP versus R-DHAP: PFS at 2 years was 24% versus 26% (hazard ratio [HR], 1.12; 95% CI, 0.89 to 1.42; P = .33); event-free survival at 2 years was 16% versus 18% (HR, 1.10; P = .35); and overall survival at 2 years was 41% versus 38% (HR, 0.90; P = .38). Positron emission tomography negativity before ASCT was highly predictive for superior outcome. Conclusion No difference in efficacy was found between O-DHAP and R-DHAP as salvage treatment of relapsed or refractory DLBCL.

Abstract Abstract 3956 Poster Board III-892 BACKGROUND During the last decade the outcome of patients with diffuse large B-cell lymphoma (DLBCL) has significantly improved by the addition of rituximab (R) to the standard chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP). Despite this improvement in response rates, event- progression and overall survival, about one third of the patients with DLBCL will eventually fail. The main therapeutic efficacy of rituximab is not fully elucidated. One major effector mechanism is by antibody dependent cellular cytotoxicity (ADCC) mediated by cell-bound rituximab via its FCg part that activates effector cells by binding to their Fcg receptor (FCγR). Three classes and eight subclasses of FCγR have been described. SNPs have been detected for FcgRIIA at amino acid position (AA) 131 where histidin is substituted by arginin (131 R/H) and for FCγRIIIA at position 158, where phenylalanine is substituted by valine (158 V/F). These SNPs have an increased affinity to Fcg and induce a stronger ADCC which explains better responses to rituximab treatment in follicular lymphoma. The aim of this study was to determine the impact of FCγRIIA and FCγRIIIA SNPs on the outcome R-CHOP chemotherapy in elderly patients with newly diagnosed DLBCL. PATIENTS AND METHODS In the RICOVER-60 therapy study 1222 elderly patients (aged 61-80 years) were randomly assigned to 6 or 8 cycles of CHOP, both with or without rituximab (Pfreundschuh et al., Lancet Oncology 2008). The control group (n=100) consisted of anonymous healthy blood donors of Saarland University Institute of Transfusion Medicine. Available for this study were peripheral blood samples from 570 patients who were representative for the entire RICOVER-60 population. The 2 FCgR SNPs FCγ-RIIa AA 131 R/H and FCγ-RIIIa 158 V/F were determined and univariate and multivariate analyses adjusting for the IPI-relevant risk factors (LDH, ECOG performance status, advanced stage and >1 extranodal involvement) were performed for the entire study population and separately for patients receiving or not receiving rituximab. RESULTS Frequencies of FCγ-RIIa and FCγ-RIIIa polymorphisms were not different in healthy controls compared to DLBCL patients. In our statistical analyses finaly 512 patients were included. The characteristic for the groups were for group 1 (6x CHOP-14) 127 patients (24.8%), for group 2 (8x CHOP-14) 122 patients (23.83%), for group 3 (6x CHOP-14+8x rituximab) 124 patients (24.22%) and for group 4 (8x CHOP-14 + 8x rituximab) 139 patients (27.15%) [fisher test (included vs excluded): p=0.4691]. The median age at admission was the same for included and excluded patients. The gender characteristics for the included patients were well balanced [fisher test (included vs excluded): p=1.0000]. The median observation time for the included vs. excluded patients was 40.25 months vs. 34.50 months. This verification shows that the collective of included patients represents the whole RICOVER-60 population. Statistical analyses of overall survival, 3 year event-free survival and 3 year overall-survival were done for the complete RICOVER-60 population. 3-year event-free survival was 47.2% after six cycles of CHOP-14 (95% CI 41.2-53.3), 53.0% (47.0-59.1) after eight cycles of CHOP-14, 66.5% (60.9-72.0) after six cycles of R-CHOP-14, and 63.1% (57.4-68.8) after eight cycles of R-CHOP-14. 3-year overall survival was 67.7% (62.0-73.5) for six cycles of CHOP-14, 66.0% (60.1-71.9) for eight cycles of CHOP-14, 78.1% (73.2-83.0) for six cycles of R-CHOP-14, and 72.5% (67.1-77.9) for eight cycles of R-CHOP-14. Compared with treatment with six cycles of CHOP-14, overall survival improved by -1.7% (-10.0-6.6) after eight cycles of CHOP-14, 10.4% (2.8-18.0) after six cycles of R-CHOP-14, and 4.8% (-3.1-12.7) after eight cycles of R-CHOP-14. In summary, event-free, progression free, overall survival and complete remission rates were not different among patients with FCγ-RIIa (AA 131R/H) and FCγ-RIIIa (AA 158 V/F) SNPs, irrespective of whether the entire RICOVER-60 population was analysed or when patients treated with and without rituximab were analysed separately. CONCLUSIONS FCγ-RIIa and FCγ-RIIIa SNPs have no influence on the outcome of patients treated with CHOP-14 with or without rituximab. Therefore, modifications of schedule and dose of rituximab according to the underlying FCγ-R SNPs are not justified.

Abstract Abstract 1952 Poster Board I-975 Background: Vitamin D is a naturally occurring steroid hormone. In addition to its well-established role in maintaining serum calcium homeostasis, vitamin D has effects on cellular differentiation, proliferation, apoptosis, and angiogenesis. Vitamin D3 is naturally produced in skin in response ultraviolet-B (UVB) radiation from the sun. Several recent studies, however, have shown that a high proportion of community-dwelling subjects in both tropical and temperate climates are deficient in vitamin D, and that subjects in northern latitudes often require dietary supplementation to maintain vitamin D sufficiency. Further, several reports now suggest that vitamin D sufficiency is protective against the development of several cancers, including non-Hodgkin lymphoma (NHL). However, it is not known whether vitamin D impacts prognosis in diffuse large B-cell lymphoma (DLBCL), the most common NHL subtype. Methods: We evaluated serum vitamin D concentrations in two cohorts of DLBCL patients. The first cohort consisted of 374 patients newly diagnosed from September 2002-February 2008 who were prospectively enrolled in the University of Iowa/Mayo Clinic Lymphoma SPORE Molecular Epidemiology Resource, an observational study in which neither therapeutic nor diagnostic management is prescribed. All serum was obtained within 120 days of diagnosis, and was prior to treatment in 221 (59%). In the second study, 62 patients newly diagnosed from February 2006-August 2007 were enrolled on NCCTG clinical trial N0489, and all serum was obtained before the first course of therapy. Central pathology review was performed on all patients to confirm the diagnosis of DLBCL. Serum 25-hydroxyvitamin (25-OH-VitD) levels were measured by the gold standard method for vitamin D determination: liquid chromatography tandem mass spectroscopy (LC-MS/MS). Vitamin D deficiency was defined as total serum 25-OH-VitD < 25 ng/mL (62.5 nmol/L). SPORE patients were followed per a standard protocol for event-free (progression, retreatment, or death due to any cause) and overall survival (EFS and OS, respectively); N0489 patients were followed in a similar way per the clinical trial protocol. We used Cox regression to estimate hazard ratios (HRs) and 95% confidence intervals (CI). Results: SPORE patients were primarily treated with immunochemotherapy (83%); all N0489 patients were treated with epratuzumab + R-CHOP21. The median age at diagnosis was 62 years (range, 19-93) for SPORE patients and 61 years (range, 21-82) for N0489 patients. Median follow-up for SPORE patients was 36 months (range, 1-77) with 95 deaths and 131 events; median follow-up for N0489 patients was 24 months (range, 7-39) with 13 deaths and 18 events. Vitamin D deficiency was identified in 188 SPORE patients (50%) and 15 N0489 patients (24%). There were no differences in the prevalence of vitamin D deficiency by age, IPI, or whether serum was obtained prior to starting treatment (all p > 0.28). Vitamin D deficiency was associated with inferior overall (HR=2.33, 95% CI 1.53-3.57, logrank p = 0.0001) and event-free survival (HR=1.71, 95% CI 1.20-2.44, logrank p = 0.003) in the SPORE cohort. These associations remained significant after adjusting for IPI and treatment: OS HR=1.97, 95% CI 1.27-3.07; EFS HR=1.47, 95% CI 1.02-2.21. These results were similar for the subset of SPORE patients who were treated with R-CHOP. The HRs for vitamin D deficiency and event-free survival were consistent in the N0489 patients (HR=1.63, 95% CI 0.61-4.35, IPI adjusted HR=1.43, 95% CI 0.53-3.85), although these results lacked precision due to a smaller sample size. We were unable to evaluate OS in N0489 due to the small number of deaths. Conclusions: Approximately 50% of all DLBCL patients in this northern US latitude population are vitamin D deficient at the time of diagnosis and treatment.

Abstract The neutrophil/lymphocyte ratio (N/L) at diagnosis has been shown to be a prognostic factor for survival in solid tumors. An increase in the neutrophil count is a marker of inflammation which is an essential part of the neoplastic process. Conversely, a decrease of the peripheral lymphocyte count might reflect an impairment of the host defense mechanism associated with advanced and aggressive cancers. Since There are only few reports on the N/L ratio in non-Hodgkin lymphomas. We studied the prognostic role of the N/L ratio at diagnosis in 286 patients with diffuse-large-B-cell lymphoma (DLBCL) enrolled in a multicenter prospective registry of the Lazio region in Italy The median age at diagnosis was 69 years (27-91) and the female/male ratio was:141/145.First, we analyzed for associations between N/L ratio and patient characteristics. The optimal cut-off value for the N/L was obtained using the Receiver Operating Curve (ROC) and according to the published data in solid tumor. N/L ≥ 4 was significantly associated with presence of B-symptoms (p=0.01) and elevated LDH levels (p=0.007) at diagnosis. Most patients were treated with R-CHOP (rituximab, cyclophosphamide, Adriamycin, vincristine, and prednisone) or R-CHOP-like (90%). Complete Remission (CR) + Partial Remission (PR) were obtained in 210/286 (73%). The median follow up period was 15 months (range: 1-33 months): 27 patients died for lymphoma relapse/progression and 16 for other causes. Patients with N/L ≥ 4 experienced a higher rate of relapse, while N/L< 4 was associated to a significantly better Overall (OS, P < 0.05) and Event Free Survival (EFS, P< 0.01). (Figure 1, panel a and b).Furthermore, considering only patients with IPI score ≤ 3, those with N/L <4, (Figure 1, panel c), had a better OS compared to those with N/L≥ 4 (P < 0.01). Conclusion: The N/L ratio may be a useful and unexpensive prognostic marker in patients with DLBCL. The inferior outcome observed in patients with N/L ≥ 4 might reflect an immune and inflammatory imbalance induced by a more aggressive tumor, releasing directly or indirectly inflammatory cytokines and/or inducing immune suppression or exhaustion. A link with inflammation is suggested by the correlation of N/L ratio ≥ 4 with high LDH levels and the presence of B symptoms. Figure 1. Panel A. Overall Survival (OS) and Panel B.

Cd44v6 Expression

Abstract Background: CD44 variants have been implicated in metastasis and as an unfavorable prognosis factor in many types of cancers. Our previous study had showed that CD44v6 expression implied a poor clinical outcome in diffuse large B cell lymphoma (DLBCL) patients treated with CHOP. However, it is remains unknown the prognostic value in DLBCL patients treated with R-CHOP due to our sample sizes. Therefore, to examine the prognostic value of CD44v6 expression in DLBCL patients, we performed this retrospective study. Methods: All 141 patients diagnosed as de novo DLBCL according to WHO classification were further confirmed. All patients treated with R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone). The expression of CD44v6 was analyzed by immunohistochemistry (IHC). IHC was performed by an automated immunostainer complying with the instructions of the protocols. Results: Among all the 141 patients, the expression of CD44v6 was observed in 41 cases (29.1%). CD44v6 is expressed predominantly in non-germinal center type DLBCL. There was no significant difference in gender, age, B symptoms, performance status, LDH, stage and IPI score between patients with and without CD44v6 expression. Patients with CD44v6 expression showed significant inferior overall survival, but not event-free survival compared with CD44v6-negative patients. (p=0.022 and p=0.142, respectively).Multivariate analysis showed that the expression of CD44v6, independent of the international prognostic index and cell of origin, implied a poor overall survival (HR=2.223; 95% CI= 1.007-4.906, p=0.048), but not event-free survival (HR=1.457; 95% CI=0.773-2.745, p=0.245). Conclusions: These data suggest that the expression of CD44v6 implied poor outcome in DLBCL patients treated with R-CHOP. Disclosures No relevant conflicts of interest to declare.

Introduction: Diffuse-large B cell lymphoma (DLBCL) is the most common lymphoma associated with Hepatitis C Virus (HCV) and Human Immunodeficiency Virus (HIV). During the past decades, the incidence of HIV-related lymphomas has declined; however, it still remains a major cause of morbidity and mortality in this population. Before highly effective antiretroviral therapy for HIV was introduced, individuals with HIV-related DLBCL had worse complete response and survival rates compared to their uninfected counterparts. Additionally, recent studies have shown that relapse rates are lower for DLBCL patients that achieve HCV sustained virological response (SVR). Nevertheless, outcomes in patients with active HCV infection among patients with HIV-related DLBCL have not been reported yet. This study is aimed to compare the clinical outcomes in HIV-related DLBCL among patients with and without active HCV infection. Methods: Patients with HIV infection and newly diagnosed DLBCL between 2005 and 2017 at Montefiore Medical Center/Albert Einstein College of Medicine were identified using the institutional software Clinical Looking Glass. Cases were grouped into concomitant HIV and HCV infection (HIV + HCV) or HIV alone (HIV) based on HCV antibody and viral load counts at DLBCL diagnosis. Patients with active hepatitis B infection were excluded. Data regarding demographics, laboratory parameters, HCV treatment, lymphoma treatment and clinical outcomes including complete response (CR), progression of disease (POD) and relapse were collected by manual chart review and compared among groups. SVR was defined as undetectable HCV RNA level 12 weeks after HCV treatment completion. Clinical outcomes were compared between patients with and without active HCV at the time of outcome evaluation. For this purpose, patients that achieved SVR for HCV were analyzed in the HIV group. Kaplan-Meier curves were plotted to compare 12-months relapse-free survival (RFS) among groups. Statistical analysis was performed using Stata 14.1. Results: A total of 63 patients were identified, of whom 45 (71.4%) had HIV alone (HIV) and 18 (28.6%) had concomitant active HCV and HIV infection (HIV + HCV). The median age was 49 years (IQ: 40-54), there were 39 (61.9%) males, 27 (42.9%) were Non-Hispanic Black and 27 (42.9%) were Hispanic. At DLBCL diagnosis, the majority of cases had advanced stages (stage 3: 15; 25% and stage 4: 40; 66.7%), the median CD4 count was 117 (IQ: 65-217) and 45 (72.6%) had AIDS. Baseline characteristics did not differ among groups. Of 63 patients, 53 (84.1%) were treated for DLBCL. Treatment regimens included DA-EPOCH (28; 50.9%), CHOP (22; 40%) and others (3; 9.1%). Rituximab was given to 33 cases (57.9%). Within the HIV + HCV group, only 3 (16.7%) patients received treatment for HCV; all of them were treated with ledipasvir/sofosbuvir and achieved SVR. In the full cohort, CR was achieved in 17 (32.1%) treated patients and 19 (35.9%) had POD. The CR rate was lower for patients with active HCV + HIV compared to HIV alone (7.1% vs. 41%, p=0.02) and there was no difference in POD among groups (28.6% vs. 38.5%, p=0.37). Patients with active HCV + HIV had a significantly lower 18-month RFS compared to those with HIV (62.9% vs. 87.4%, p=0.035). In a multivariate model adjusted for stage, AIDS and rituximab use; active HCV + HIV was a predictor for relapse (OR:6.36, 95% CI: 1.01 - 39.9, p=0.048). Conclusions: Despite available and effective treatment against HCV infection, only a minority of patients with DLBCL-related HIV received HCV treatment. Active HCV seems to play a role in the outcomes of patients treated for DLBCL and was found to be a predictor for relapse. Hence, HCV treatment should be considered for patients with HIV-related DLBCL. Disclosures Shah: Physicians' Education Resource: Honoraria.

Aim: To describe practices and outcomes in veterans with relapsed/refractory diffuse large B-cell lymphoma. Patients & methods: Using Veteran Affairs Cancer Registry System and electronic health record data, we identified relapsed/refractory diffuse large B-cell lymphoma patients completing second-line treatment (2L) in 2000–2016. Treatments were classified as aggressive/nonaggressive. Analyses included descriptive statistics and the Kaplan–Meier estimation of progression-free survival and overall survival. Results: Two hundred and seventy patients received 2L. During median 9.7-month follow-up starting from 2L, 470 regimens were observed, averaging 2.7 regimens/patient: 219 aggressive, 251 nonaggressive. One hundred and twenty-one patients proceeded to third-line, 50 to fourth-line and 18 to fifth-line treatment. Median progression-free survival in 2L was 5.2 months. Median overall survival was 9.5 months. Forty-four patients (16.3%) proceeded to bone marrow transplant. Conclusion: More effective, less toxic treatments are needed and should be initiated earlier in treatment trajectory.
