Abstract [Introduction] Oxidative stress caused by the increased production of reactive oxygen species (ROS) or decreased efficacy of the antioxidant system is implicated in the pathogenesis of various disease entities, such as atherosclerosis, cardiovascular disease, renal failure, malignant tumors, and autoimmune diseases. Recent observations suggested that oxidative stress is closely related to all aspects of cancer. Oxidative stress markers are prognostically important in various cancers including diffuse large B-cell lymphoma (DLBCL). However, the prognostic role of serum reactive oxygen metabolites (ROMs) in DLBCL is still unknown. The objective of this study is to evaluate the role of serum ROMs in patients with DLBCL. [Methods] We enrolled 52 patients with DLBCL who were treated at our institution between 2012 and 2014. To assess oxidative stress, instead of measuring serum ROS directly, we measured serum d-ROMs (the derivatives of Reactive Oxygen Metabolites) levels. In the present study, serum d-ROMs levels were prospectively examined in 52 patients with DLBCL and 12 healthy subjects by using the Free Radical Analytical System 4 (FRAS 4, Wismerll Co. Ltd., Tokyo, Japan). The d-ROMs test has been successfully used to evaluate oxidative stress in a very large number of studies on humans and animals. The d-ROMs test essentially determines the concentration of hydroperoxides in the blood, which are substances that belong to a broad class of reactive oxygen metabolites. The d-ROMs concentration is expressed in Carratelli Units (1 CARR U = 0.08mg hydrogen peroxide/dl). The study protocol and sampling were approved by the Institutional Review Board of Yokohama Municipal Citizen's Hospital, and it was carried out in accordance with the Declaration of Helsinki. [Results] The median follow-up time was 52 months. Median age at diagnosis was 74 years (range, 39-91 years) and 60% were male. 34 patients (65%) were stage 3-4 and 33 patients (63%) were R-IPI poor risk. The serum d-ROMs levels in patients with DLBCL were significantly elevated compared with normal controls (578.9+/-194.3 vs. 286.8+/-24.2 CARR U, P<0.001). In 52 DLBCL patients, patients with high serum d-ROMs levels (≥513 CARR U) had significantly shorter overall survival (OS) than those with low serum d-ROMs levels (<513 CARR U) (5-year OS, 37.9% versus 77.7%, respectively; P<0.001) (Figure. 1). In multivariate analysis, parameters having independent adverse significance for OS were: high serum d-ROMs levels (≥513 CARR U) (p=0.002, HR 5.17), high LDH levels (p=0.008, HR 4.58), and extranodal involvement >1 (p=0.002, HR 4.57). [Conclusion] In the present study we demonstrated that elevated serum d-ROMs levels are associated with poor prognosis in patients with DLBCL. In particular, our data proved that a high serum d-ROMs level is an independent prognostic factor for survival in patients with DLBCL. These results suggest that oxidative stress may have an important role in DLBCL and may be also a useful prognostic biomarker. Since our results are based on a small-sized analysis, further large prospective studies are warranted to verify this conclusion. Disclosures No relevant conflicts of interest to declare.

Abstract [Introduction] Follicular lymphoma (FL) is an indolent non-Hodgkinfs lymphoma (NHL), with a highly variable clinical course that can range from indolent to rapidly progressive disease, including the transformation to aggressive NHL. Oxidative stress caused by the increased production of reactive oxygen species (ROS) or decreased efficacy of the antioxidant system is implicated in the pathogenesis of various disease entities, such as atherosclerosis, cardiovascular disease, renal failure, malignant tumors, and autoimmune diseases. Recent observations suggested that oxidative stress is closely related to all aspects of cancer. Oxidative stress markers are prognostically important in various cancers including diffuse large B-cell lymphoma (DLBCL). However, the prognostic role of oxidative stress in FL is still unknown. The objective of this study is to evaluate the role of oxidative stress in patients with FL. [Methods] 8-hydroxy-2-deoxyguanosine (8-OHdG), which originates from damaged DNA repaired by non-specific endonucleases and specific glycosylates and is eliminated into urine, is widely used as a sensitive biomarker of oxidative stress. Urinary 8-OHdG levels have been reported to be elevated in patients with various malignancies. In the present study, urinary 8-OHdG levels were prospectively examined in 30 patients with FL by using a novel automatic oxidative stress analyzer, ICR-001. We also evaluated serum d-ROMs (the derivatives of Reactive Oxygen Metabolites) levels by using the Free Radical Analytical System 4 (FRAS 4, Wismerll Co. Ltd., Tokyo, Japan). The d-ROMs test has been successfully used to evaluate oxidative stress in a very large number of studies on humans and animals. The d-ROMs test essentially determines the concentration of hydroperoxides in the blood, which are substances that belong to a broad class of reactive oxygen metabolites. The d-ROMs concentration is expressed in Carratelli Units (1 CARR U = 0.08mg hydrogen peroxide/dl). The study protocol and sampling were approved by the Institutional Review Board of Yokohama Municipal Citizen's Hospital, and it was carried out in accordance with the Declaration of Helsinki. [Results] Median age at diagnosis was 70 years (range, 43-84 years) and 53% were male. According to the WHO pathological grading, grade 1 FL was observed in 16 patients (53%), grade 2 FL in 8 patients (27%), and grade 3 FL in 6 patients (20%). FLIPI scores were 0 to 1 in 27%, 2 in 27%, and 3 to 5 in 46%. The urinary 8-OHdG levels in patients with FL (N=30) were elevated compared with normal controls (N=20) (19.7+/-10.3 vs. 13.7+/-3.4 ng/mg/Cr, P=0.01). In 30 FL patients, patients with high urinary 8-OHdG levels (over 23.9 ng/mg/Cr) had significantly shorter overall survival (OS) than those with low urinary 8-OHdG levels (under 23.9 ng/mg/Cr) (3-year OS, 33.3% versus 90.5%, respectively; P<0.001) (Figure. 1). The serum d-ROMs levels in patients with FL were significantly elevated compared with normal controls (543.9+/-199.4 vs. 281.1+/-25.9 CARR U, P<0.001). Patients with high serum d-ROMs levels (over 519 CARR U) had significantly shorter overall survival (OS) than those with low serum d-ROMs levels (under 519 CARR U) (3-year OS, 41.7% versus 94.4%, respectively; P<0.001) (Figure. 2). In univariate analysis, high 8-OHdG levels, high d-ROMs levels, high PS, high LDH levels, high tumor burden (GELF criteria), high beta-2 microglobulin levels, and high FLIPI score were associated with poor OS in patients with FL. In multivariate analysis, parameters having independent adverse significance for OS were: high serum d-ROMs levels (over 519 CARR U) (p=0.01, HR 15.68), high LDH levels (p=0.02, HR 12.25). [Conclusion] In the present study we demonstrated that elevated urinary 8-OHdG levels and serum d-ROMs levels are associated with poor prognosis in patients with FL. In particular, our data proved that a high serum d-ROMs level is an independent prognostic factor for survival in patients with FL. These results suggest that oxidative stress may have an important role in FL and also may be a useful prognostic biomarker. Since our results are based on a small-sized analysis, further large prospective studies are warranted to verify this conclusion. Disclosures Nakazato: Mundipharma KK: Research Funding.

Abstract Introduction The role of interim-PET (i-PET), after two cycles of chemotherapy, in advanced stage Hodgkin's lymphoma is well defined; the same role in diffuse large B cell lymphoma (DLBCL) is still controversial. The Fondazione Italiana Linfomi planned a prospective randomized phase III trial, addressed to young poor prognosis DLBCL patients at the diagnosis, with a 2x2 factorial design aimed at investigating the possible benefit of intensification with R-HDC+ASCT after R-dose-dense chemotherapy delivered at two different level of dose (R-CHOP14/R-MegaCHOP14). During this study an ancillary study was designed to define the prognostic impact of i-PET on progression free survival (PFS) after two cycles of immunochemotherapy in all treatments arms. Patients and methods As described by Vitolo et al (oral communication, abs 688 ASH 2012), patients were stratified according to aa-IPI and randomized at diagnosis to receive: R-CHOP14 x 8 cycles; R-MegaCHOP14 (1200 mg/sqm Cyclophosphamide, 70 mg/sqm Doxorubicin, standard dose Vincristine and Prednisone) x 6; R-CHOP14 x 4 + R-HDC (Rituximab + High Dose Cytarabine + Mitoxantrone + Dexamethasone) followed by BEAM and ASCT; R-MegaCHOP14 x 4 + R-HDC + BEAM and ASCT. G-CSF support was mandatory. Seventeen centers agreed to participate in the study and enrolled patients. All evaluable patients had performed basal PET and i-PET. A visual dichotomous criteria, according to Deauville Criteria (First Consensus Conference, 2009), was used to define the i-PET result. The final response was identified according to 2007 Cheson response criteria. Results From June 2005 to September 2010, 399 patients were randomized in the overall DLCL04 study and 130 were enrolled for the ancillary PET study , 69 in the R-HDC+ASCT and 61 in R dose dense therapy respectively. The clinical characteristics, as in the overall DLCL04 study, were well balanced among the four arms of therapy excluding a selection bias in the group of patients studied with i-PET. The i-PET result was positive in 74 patients and negative in 56 patients, no differences were observed between negative and positive i-PET results according to clinical characteristics and group of treatment. In particular, in R-dose dense arm 27 were negative and 34 positive, in R-HDC+ASCT 29 were negative and 40 positive, according to immunochemotherapy scheme in R-CHOP14 29 were negative and 40 were positive, in MegaCHOP14 27 were negative and 34 were positive. With a median follow-up of 36 months, 3-year PFS and 3-year Overall Survival (OS) rates for the whole series were: 64% (95% CI:59-69) and 79% (95% CI:74-83) respectively. No differences in PFS was reported according to i-PET result. In particular 3-year PFS were 87%(95% CI:75-94) in i-PET negative patients and 76% (95% CI: 65-85) in i-PET positive patients respectively (p: 0.09 The 3-year PFS according to I- PET results in the different treatment arm were: in the R-HDT+ASCT group i-PET negative or i-PET positive patients had a 3-year PFS of 83% (95% CI:63-92) and 79% (95% CI:63-89) respectively; in the R-dose dense i-PET negative or i-PET positive patients had a 3-year PFS of 92% (95% CI:73-98) and 72% (95% CI:54-85) with a p value near the significance (0.07). According to OS, i-PET negative and i-PET positive patients had a 3-year OS of 89%(95% CI:76-95) and 83%(95% CI:72-90) respectively, p=0.219. Conclusions In our multicenter prospective study, addressed to young poor prognosis DLBCL patients at the diagnosis, i-PET, performed after two immunochemotherapy cycles and analyzed with a visual method, is not able to identify two different risk population. To confirm our data, we are planning in the near future a centralized revision of all evaluable PET. In conclusion, our feeling is that the i-PET after two cycles in poor prognosis DLBCL patients is too early to predict a chemorefractory disease and more parameters must be considered to define clinical response in these patients.

Abstract CD19 is one of the most representative B-cell markers, and is widely used in diagnostic immunophenotyping in diffuse large B-cell lymphoma (DLBCL). However, it is known that the frequency of CD19 expression in DLBCL is less than that of CD20, and the clinical significance of CD19 expression has not yet been thoroughly examined. To clarify the clinical behavior of CD19-negative (CD19−) DLBCL, we have compared the clinical features, immunophenotype, and prognosis in relation to CD19 expression. The diagnosis of DLBCL was made according to the WHO Classification. We examined CD19 expression by means of immunohistochemistry using frozen sections with a monoclonal antibody, Leu12 (Becton Dickinson). Between 1987 and 2002, 227 cases of de novo DLBCL were examined the expression of CD19 in our laboratory. Anthracycline-containing chemotherapies were selected as the first-line treatment in 192 cases (85%). None was treated with rituximab. CD19 was expressed in 205 cases (90%), and 226 cases (99%) were positive for CD20. In 22 cases of CD19-negative (CD19−) DLBCL, the median age was 63 (39–79), and the male/female ratio was 11/11. According to CD19 expression, our DLBCL cases showed the following clinical features: male/female (CD19+ DLBCL 111/94, CD19− DLBCL 11/11: NS), age>60 (70%, 55%: NS), PS>1 (20%, 36%: P=0.07), sLDH>1xN (44%, 73%: P=0.01), extranodal involvement>1 site (12%, 18%: NS), stage III/IV (41%, 54%: NS), B symptom present (29%, 45%: NS). CD19− DLBCL expressed BCL2 protein less frequently than CD19+ DLBCL (P=0.03). The expression of CD5, CD10, CD21, BCL6, and MUM1 did not show a significant difference between CD19+ DLBCL and CD19− DLBCL. CD19− DLBCL showed significantly worse survival than CD19+ DLBCL (P=0.04, log-rank test). These findings suggest that the loss of CD19 expression in DLBCL is associated with high serum LDH level and poor prognosis. Simultaneous examination of CD19 and CD20 in diagnosis of DLBCL is recommended. Overall survival for patients with CD19+ DLBCL and with CD19− DLBCL. Overall survival for patients with CD19+ DLBCL and with CD19− DLBCL.

AbstractStandard chemotherapies for diffuse large B-cell lymphoma (DLBCL), based on the induction of exogenous DNA damage and oxidative stress, are often less effective in the presence of increased MYC and BCL-2 levels, especially in the case of double hit (DH) lymphomas harboring rearrangements of the MYC and BCL-2 oncogenes, which enrich for a patient’s population characterized by refractoriness to anthracycline-based chemotherapy. Here we hypothesized that adaptive mechanisms to MYC-induced replicative and oxidative stress, consisting in DNA damage response (DDR) activation and BCL-2 overexpression, could represent the biologic basis of the poor prognosis and chemoresistance observed in MYC/BCL-2-positive lymphoma. We first integrated targeted gene expression profiling (T-GEP), fluorescence in situ hybridization (FISH) analysis, and characterization of replicative and oxidative stress biomarkers in two independent DLBCL cohorts. The presence of oxidative DNA damage biomarkers identified a poor prognosis double expresser (DE)-DLBCL subset, characterized by relatively higher BCL-2 gene expression levels and enrichment for DH lymphomas. Based on these findings, we tested therapeutic strategies based on combined DDR and BCL-2 inhibition, confirming efficacy and synergistic interactions in in vitro and in vivo DH-DLBCL models. These data provide the rationale for precision-therapy strategies based on combined DDR and BCL-2 inhibition in DH or DE-DLBCL.

Introduction: Micro-RNAs (miRNAs) are 19-24 nucleotide non-coding RNAs that regulate gene expression through the inactivation of their messenger RNA. Previous studies have demonstrated the important role of some miRNAs in the development of cancer. Specifically, in diffuse large B cell lymphoma (DLBCL), miRNAs involved in lymphomagenesis were identified but understanding their biological function continues to be a challenge. Nevertheless, the pathogenesis effects of some miRNAs such as miR-125a, miR-17-92 cluster or mi-R-155 are well characterized. Some studies suggest that miRNAs also possess a prognostic potential role in DLBCL. For this reason, our objective was to analyze the different miRNAs involved in the chemo-sensitivity or resistance to the first line treatment, their correlation with standard prognostic factors at diagnosis and the role of these miRNAs in survival in patients with DLBCL. Material and methods: Patients homogeneously treated with R-CHOP from 1999-2013 were reviewed from 3 Spanish centers. They were retrospectively obtained from Pathology Department registry to avoid selection bias. We included those patients with valid genomic material in formalin-fixed-paraffin-embedded tissue and with available clinical data. Samples were processed using the miRNA 4 Affymetrix microarrays kit in a discovery group that included 2 cohorts (patients with durable complete remission (CR) versus refractory or early relapsing patients). Those miRNAs with differential expression were validated in the whole series with quantitative RT-PCR. We also analyzed the role of these miRNAs as predictors of event-free survival (EFS) and overall survival (OS) and their relationship with standard prognostic factors in DLBCL. Results: We identified 156 patients homogeneously treated with R-CHOP. Finally, 96 samples were obtained with valid material for RNA extraction. To identify those miRNAs with prognostic implication, a discovery cohort of 12 patients was used in which all the cases had poor prognosis with high tumor load and advance disease (III-IV stage and unfavorable R-IPI). On this basis of poor prognosis, 2 groups were defined totally opposed from the point of view of the treatment response and evolution: chemo-resistance group (n=6) including refractory or relapsed (RR) patients (first 12 months) and chemo-sensitive group (n=6) including patients with at least 3 years of CR. A hierarchical clustering was performed in which 26 miRNAs differentially expressed were identified. A screening of miRNAs was carried out based on the fold-change and pathways involved and finally we obtained 10 miRNAs differentially expressed in RR group. The validation of these miRNAs was performed with quantitative RT-PCR in the whole series which finally included 68 samples with valid material. A univariate survival analysis including clinical prognostic factors and the selected 10 miRNAs was performed. We confirmed that 7 of them (miR-20b-5p, miR-1244, miR-6840-3p, miR-1231, miR-193b-5p, miR-6860-5p y miR-199a-5p) significantly influenced EFS and 6 of them (miR-1244, miR-1231, miR-193b-5p, miR-885-3p, miR-182-5p y miR-199a-5p) on OS. From these 10 miRNAs, only 3 had a significant prognosis role not only for EFS but also for OS and progression-free survival (PFS): miR-1244, miR-193b-5p and miR-1231. The overexpression of miR-1244 and miR-193-5p were associated with advance stage and worse clinical prognosis factors (p<0.05). A multivariate analysis was performed including clinical and biological variables and we obtained that the overexpression of miR-1231, high R-IPI and a reduction of relative dose intensity (RDI) >15% were independently associated with worse SG and EFS (Figure 1). In previously reported studies, these 3 miRNAs have been related with proliferative events such as the overexpression of myc or anti-apoptosis. Also, the miR-1231 may be related with new lymphomagenesis pathways associated to viral infections. Conclusions: Through a discovery group focused on progression/refractoriness, a group of new miRNAs differentially expressed on chemo-resistant patients with DLBCL was identified. The overexpression of miR-1244 and miR-193-5p was associated with more extensive disease and worse clinical prognostic factors. The high R-IPI, reduction of >15% RDI and the overexpression of miR-1231 were independently associated with worse EFS and OS.

Myeloid-derived suppressor cells (MDSCs) are defined as negative regulators that suppress the immune response through a variety of mechanisms, which usually cluster in cancer, inflammation, and autoimmune diseases. This study aims to investigate the correlation between M-MDSCs and the clinical features of diffuse large B-cell lymphoma (DLBCL) patients, as well as the possible accumulation mechanism of M-MDSCs. The level of M-MDSCs is significantly increased in newly diagnosed and relapsed DLBCL patients. Regarding newly diagnosed DLBCL patients, the frequency of M-MDSCs is positively correlated with tumor progression and negatively correlated with overall survival (OS). More importantly, the level of M-MDSCs can be defined as a biomarker for a poor prognosis in DLBCL patients. Additionally, interleukin-35 (IL-35) mediates the accumulation of M-MDSCs in DLBCL patients. Anti-IL-35 treatment significantly reduces levels of M-MDSCs in Ly8 tumor-bearing mice. Thus, M-MDSCs are involved in the pathological process of DLBCL. Targeting M-MDSCs may be a promising therapeutic strategy for the treatment of DLBCL patients.
