Abstract Introduction: Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin's lymphoma. We conducted a retrospective study to analyze the clinicopathological characteristics, cell of origin, response to therapy, and the outcome of patients with DLBCL. Materials and Methods: This was a retrospective study which included all patients with DLBCL registered at our center, between May 1, 2013, and July 31, 2015. The data regarding demography, clinical presentation, histopathology, stage, prognostic index, treatment, and treatment-related outcome were collected from prospectively maintained clinical case records of the patients. Results: In the study, we included 267 patients. The median age is 49 (20–81) years with male: female ratio of 2:1. B symptoms were seen in 124 (45%) of patients. Early Stages (I and II) were seen in 130 (52%) patients, while advanced Stages (III and 1V) were seen in 119 (48%) patients. Bulky disease (>7.5 cm) was seen in 30% of cases, and bone marrow was involved in 12%. Extranodal involvement is present in 35% of cases. Cell of origin data was available in 160 (60%) of cases, of which 88 (55%) were germinal center and 72 (45%) were activated B cell in origin. The distribution according to the international prognostic index (IPI) was as follows: low risk 40%, intermediate risk 45%, and high risk in 15%. Rituximab was used in 45% of cases. The overall response rate was 84% with a complete response (CR) rate of 70.5%. The CR rates were better with RCHOP compared with CHOP (77% vs. 61.5%, P = 0.001) and good-risk IPI (83.3% vs. 65.2%, P < 0.001) compared with intermediate- and high-risk IPI. Median follow-up period was 24 months, and 2-year event-free survival (EFS) was 70%. The presence of B symptoms, high IPI, failure to attain CR, poor PS, and nonrituximab-based chemotherapy were significantly associated with lower EFS. Conclusions: This is the first study from India, which investigated the impact of chemotherapy with or without rituximab in context of cell of origin. Adding rituximab to CHOP showed better response rate and EFS irrespective of cell of origin.

Abstract Abstract 1663 Poster Board I-689 Introduction Lymphomatous meningitis (LM) in patients with Diffuse Large B Cell Lymphoma (DLBCL) is usually an early complication and with poor prognosis. Risk factors have been previously identified for this complication. DepoCyte is an extended released liposomal cytarabine formulation (LC) which has demonstrated better efficacy compared to standard cytarabine for the treatment of LM in one randomized clinical trial. Purpose and Methods A retrospective study was carried out in 24 Spanish sites including patients diagnosed of DLBCL and at risk of LM – defined by the presence of at least one of the following: retroperitoneal mass ≥ 10 cm; Waldeyer ring, sinus, vertebral or bone, and testicular involvement; LDH more than twice the upper normal limit; bone marrow involvement > 30% and serology VIH+. All patients had received LC as IT prophylaxis for LM in the period April 2005 – June 2009. Main endpoints were effectiveness (leptomeningeal involvement rate) and safety of the IT prophylaxis. Results Data from 80 patients were analyzed. Baseline characteristics were: Mean age 55 ± 16 years (range: 18-80 years). Males 74%; Ann Arbor stage IV 54%. All patients received alkylating based regimens, being R-CHOP as the most frequent one (88%). LC was administered as intrathecal prophylactic treatment for LM in all patients. 64 patients completed the IT prophylaxis treatment with a mean of 2,8 ± 0,83 administrations and a median follow up of 17 months (range: 3-40 months) (8 patient still on treatment and 8 patients died before finish prophylaxis). Just one patient (1,6%) had leptomeningeal spread: 76 years old man with primary testicular DLBCL, treated with R-CHOP regime, who did not reach complete response and died after 8 months of follow up due to respiratory failure. Twenty four patients out of eighty (30%) showed adverse events, being headache the most frequent side effect (27%), and 14% grade IV. Headache was reversible in all cases. Chemical arachnoiditis prophylaxis was given to 70 patients. Conclusions This retrospective study has shown that in DLBCL patients and high risk of LM, prophylaxis with LC was feasible and well tolerated. With a median follow up of 17 months (range: 3-40 months) the incidence of LM was 1,6 %. Prospective, randomized comparative studies versus conventional prophylaxis regimes are needed. Disclosures Off Label Use: DepoCyte is an extended released liposomal cytarabine formulation (LC) which has demonstrated better efficacy compared to standard cytarabine for the treatment of LM in one randomized clinical trial.

The aim of this single-center, retrospective study was to investigate the impact of rituximab, reconsider the validity of International Prognostic Index (IPI), and evaluate the prognostic role of the cell of origin (CoO) in a relatively young cohort. Three hundred twelve diffuse large B cell lymphoma patients (median age: 52) were included. Rituximab significantly improved the 3- and 5-year progression free survival (PFS) (70% versus 65% and 41% versus 36%, resp.; P<0.001) but led only to a slight, insignificant increase in 3- and 5-year overall survival (OS) (71% versus 77.3% and %67 versus 74.5%, resp.; P=0.264). In the young, low risk patient subgroup (aaIPI = 0&1; n=129), rituximab improved 3- and 5-year PFS and OS rates (P<0.001 and P=0.048, resp.). The efficacy of rituximab in young high risk patients was comparable to the literature. CoO data were available in 190 patients. The OS at 3 years was 79% for GC and 64% for non-GC subgroups (P=0.014). To the best of our knowledge, this is the first study which investigated the impact of R-CHOP in the context of CoO and IPI in a relatively young cohort. CoO was not an independent risk factor for prognosis in the multivariate analysis although patients with GC showed a significant survival advantage in the univariate analysis. CoO was also found to be a significant determinant of response in refractory/relapsed patients. Our results confirm the efficacy of rituximab in low and high risk, young patients outside of a randomized clinical trial setting.

Introduction: The incidence and outcome of Waldenström's macroglobulinemia (WM) patients with transformation to diffuse large B-cell lymphoma (DLBCL) are unclear. We performed a retrospective analysis to determine the incidence, clinicopathological characteristics and treatment outcome of WM patient with histologic transformation to DLBCL in our centre. Methods: Single centre chart review of WM patients in the past 10 years. Patients with histologic diagnosis of DLBCL after the diagnosis WM were included in our analysis. Results: Three of the 79 WM patients had histological transformation to DLBCL, two male and one female. Mean age at DLBCL development was 76,6 years. The mean time to transformation since diagnosis of WM was 8,3 years (14, 8 and 3 years). All three patients received at least one prior line of treatment in relation to WM (2, 1 and 3 prior lines). Different regimens used were cyclophosphamide/dexamethasone, rituximab/bendamustin, chlorambucil monotherapy, fludarabine monotherapy, R-CVP and ibrutinib monotherapy. The patients were in clinical CR from WM at the time of transformation, two patients were still on treatment. All three patients presented with advanced disease (stage IIIB, IVB, and IVA) non-GCB subtype DLBCL with at least 2 extra nodal sites. R-IPI scores were 4,5 and 4. Two patients were treated with R-miniCHOP, one patient received R-CHOP. The first patient achieved a CR at the end of treatment and is now 1,5 years in follow-up. The second patient died from pneumonia one year after achieving a CR. The third patient is in follow op since 3 months after reaching a CR at the end of treatment. Conclusion: Over the past decade transformation of WM to DLBCL was 3.7% in our centre. This is in accordance with previous data suggesting an 2.4% risk of transformation over 10 years.Time to transformation varies and no association with prior WM therapy and response to treatment can be found.All patients presented with more aggressive DLBCL in an advanced stage.All three patients achieved a CR following treatment for DLBCL, one patient died from pneumonia, two others are now in follow-up 1,5 years and 3 months respectively.
