8558 Background: Patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) are salvaged with high dose chemotherapy followed by autologous stem cell rescue. Ibritumomab tiuxetan is an anti-CD20 antibody conjugated to the radionuclide 90yttrium. 90Y ibritumomab tiuxetan has demonstrated clinical efficacy in DLBCL with a favorable toxicity profile relative to transplant. Methods: This phase II trial investigated the overall response rate (ORR), event free survival (EFS), overall survival (OS) and toxicity of treatment with ibritumomab followed by rituximab in patients with relapsed or refractory DLBCL, not candidates for transplant. Patients were treated with an initial dose of rituximab (250 mg/m2) followed one week later by ibritumomab (0.4 mCi90Y/kg or 0.3 mCi90Y/kg based on plateles) followed by 4 weekly doses of rituximab (375mg/m2). All non-progressing patients received maintenance rituximab (375 mg/m2) weekly for 4 doses every 6 months for 4 cycles. Results: 25 patients were enrolled. Median age was 79 (range 45-95). 12 of 25 (48%) had stage 3 or 4 disease. 13 (52%) had 2 or more prior regimens. At 12 weeks 5 patients (21%) had a complete response (CR), 3 (13%) a partial response, 2 (8%) stable disease and 14 (58%) progressed for an ORR of 32% (8/25). At best response 7 patients obtained a CR. Median EFS was 2.5 months. Median OS was 8.1 months. No patient who obtained CR later relapsed, with follow up of 18.3-100.1 months. Deaths unrelated to treatment occurred in remission in 5 patients. 2 patients remain free of disease at 67.4 and 100.1 months. 11 (65%) patients had grade 3 or 4 thrombocytopenia, but no significant bleeding was observed. 9 (36%) patients had grade 3 non-hematologic toxicity. Grade 1 and 2 fatigue occurred in 41%. Patients who progressed through a rituximab containing regimen were at high risk of early progression. Conclusions: The ORR of ibritumomab as salvage therapy for DLBCL compares favorably to other regimens with acceptable toxicity. Those patients with disease refractory to rituximab are not likely to benefit. For a subset of patients not candidates for salvage with autologous transplant, this treatment can produce a durable remission. Clinical trial information: NCT00110149.

Background: Not all patients with diffuse large B-cell lymphoma (DLBCL) are candidates for aggressive regimens. 90Y ibritumomab tiuxetan (90Y-IT), an anti-CD20 radionuclide-conjugated antibody, has demonstrated clinical efficacy in DLBCL with a favorable toxicity profile. Methods: This phase II trial investigated the overall response rate (ORR), event-free survival (EFS), overall survival (OS) and toxicity of treatment with 90Y-IT (0.4 or 0.3 mCi 90Y/kg based on platelets) followed by rituximab maintenance therapy in patients with DLBCL not candidates for transplant. Results: 25 patients were enrolled. At best response 8 patients obtained a complete response (CR) and 1 a partial response (ORR 36%). Median EFS was 2.5 months and OS 8.1 months. No patient who obtained CR later relapsed systemically. Two patients were free of disease at the 61- and 100-month follow-ups; 65% had grade 3/4 thrombocytopenia, but no significant bleeding was observed. Grade 3 nonhematologic toxicity occurred in 36%. Patients who had progressed through a rituximab-containing regimen responded poorly. Conclusion: The ORR of 36% with 90Y-IT as salvage therapy for DLBCL while inferior to more aggressive regimens is significant with acceptable toxicity. For a subset of patients not candidates for salvage with autologous transplant, this treatment strategy can produce a durable, long-lasting remission.

Abstract Purpose: The tolerance of patients withdiffuse large B cell lymphoma(DLBCL) receiving CHOP±R regimen was significantly different, and grade 3~4 hematologic toxicity after chemotherapy in some patients resulted in prolonged hospital stay, increased risk of infection, delayed treatment, and directly or indirectly affected short-term efficacy and long-term prognosis. Lean body mass(LBM)and L3 skeletal muscle index (L3SMI)obtained from abdominal CT of DLBCL patients were analyzed to determine whether they could be used as independent predictors of hematological toxicity of CHOP± R regimen in DLBCL patients.Methods: The patients with DLBCL who underwent CHOP±R regimen at the Cancer Center of the First Hospital of Jilin University from January 2015 to November 2018 were retrospectively analyzed. The abdominal CT of the patient was analyzed by sliceOmatic5.0 software. The third lumbar disc planar imaging was selected, and two consecutive images were taken to calculate LBM and L3SMI. Single factor and multivariate analysis were performed on the correlation of LBM, L3SMIand chemotherapy-related grade 3~4 hematologic toxicity. The ROC curve was drawn to investigate the predictive value of various human indicators on the hematologic toxicity of grade 3~4 related to chemotherapy.Results: The L3 skeletal muscle index is associated with the occurrence of grade 3~4 hematologic toxicity (leukocyte and neutropenia) in patients with diffuse large B-cell lymphoma treated with CHOP±R regimen. Those with lower L3SMI are prone to grade 3~4 hematologic toxicity.LBM is associated with the occurrence of grade 3~4 hematologic toxicity (leukopenia) in patients with diffuse large B-cell lymphoma treated with CHOP±R regimen. This with lower LBM is prone to grade 3~4 hematologic toxicity.The L3 skeletal muscle index can be used as an independent predictor of grade 3~4 hematologic toxicity (leukocyte and neutropenia) in patients with diffuse large B-cell lymphoma treated with CHOP ± R regimen. The cut-off value can be defined as 39.91 cm2/m2.Conclusion: We can draw the following conclusions:The L3 skeletal muscle index is associated with the occurrence of grade 3~4 hematologic toxicity (leukocyte and neutropenia) in patients with diffuse large B-cell lymphoma treated with CHOP±R regimen. Those with lower L3SMI are prone to grade 3~4 hematologic toxicity.LBM is associated with the occurrence of grade 3~4 hematologic toxicity (leukopenia) in patients with diffuse large B-cell lymphoma treated with CHOP±R regimen. This with lower LBM is prone to grade 3~4 hematologic toxicity.The L3 skeletal muscle index can be used as an independent predictor of grade 3~4 hematologic toxicity (leukocyte and neutropenia) in patients with diffuse large B-cell lymphoma treated with CHOP ± R regimen. The cut-off value can be defined as 39.91 cm2/m 2.

Abstract Abstract 2688 Poster Board II-664 Rituximab with cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) and dose-dense CHOP therapy has improved the treatment results of diffuse Large B-cell lymphoma (DLBCL) patients. Nevertheless, a substantial number of patients progress or relapse. Bortezomib is a proteasome inhibitor that is widely used in myeloma treatment and was recently approved for use in mantle cell lymphoma treatment. Its antitumor activity in DLBCL patients was reported in several studies, both as a single agent and in combination with chemotherapy. In this study, we tried to add bortezomib to dose-dense CHOP every 2 weeks to evaluate the complete response (CR) rate and safety of the treatment. Patients with previously untreated disseminated stage DLBCL and age 70 years or less were eligible. All patients received CHOP (Cyclophosphamide 750 mg/m2 IV, doxorubicin 50mg/m2 IV, vincristine 1.4mg/m2 IV on day 1, and prednisolone 100mg PO on days 1 to 5) and granulocyte colony-stimulating factor at a dose of 5μg/kg from days 4 to 13 every 2 weeks. Bortezomib, as recommended by the previous phase I trial, was administered at a dose of 1.6mg/m2 on days 1 and 4 of each cycle. Thirty-five patients were enrolled from March, 2007 to March 2009. Total 188 cycles of treatment were done. Twenty-six patients finished planned 6 cycles of treatment, while 9 patients could not continue all planned treatment due to treatment related toxicities and one patient experienced disease progression after 5 cycles of treatment. Twenty-four patients had a CR (92.4%), one patient had a partial response (3.8%), and one patient had a progressive disease (3.8%). Grade 3 hematologic toxicity episodes occurred including 20 anemia (10.7%), 4 neutropenia (2.1%), and 6 thrombocytopenia (3.2%). Grade 4 hematologic toxicity episodes comprised 2 anemia (1.6%), 11 neutropenia (5.9%), and 6 thrombocytopenia (3.2%). One patient died of severe infection with neutropenia. Among 35 patients, grade 3 non-hematologic toxicity occurred with fatigue (11.4%), nausea (2.9%), vomiting (5.7%), diarrhea (8.6%), abdominal pain (8.6%), and sensory neuropathy (20.0%). One patient experienced grade 4 constipation. This interim analysis shows that bortezomib plus dose-dense CHOP every two weeks showed promising activity in disseminated DLBCL patients as the first-line treatment with acceptable toxicity. Further accrual will be continued till the planned patient enrollment goal for phase II results. Disclosures: No relevant conflicts of interest to declare.

Abstract Backgrounds: Treatment of patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) not eligible to high dose therapy represents an unmet medical need. Histone deacetylases (DACs) regulate chromatin structure and function and are involved in crucial mechanisms of lymphoma cell growth. Panobinostat showed encouraging therapeutic activity in Hodgkin lymphoma, cutaneous T-cell lymphoma and other non-Hodgkin lymphomas, in studies conducted in lymphoma cell lines and in vivo in patients with advanced hematologic malignancies. Moreover, recent studies showed a potent activity of Panobinostat in DLBCL. Purpose: On this basis we performed a prospective, multicenter, phase II single arm study, to evaluate safety and efficacy of single agent Panobinostat as salvage therapy for R/R DLBCL adult patients and to evaluate a possible relationships between response and any biological features. Patients and Methods: Adult patients with R/R DLBCL who already performed high-dose chemotherapy followed by autologous stem cell transplantation (ASCT) or were not eligible for ASCT were included. The treatment plan included 6 induction courses with Panobinostat monotherapy followed by other 6 courses of consolidation; patients achieving complete response (CR), partial response (PR) or stable disease (SD), underwent maintenance for a maximum of 36 courses. In each 28-days course, Panobinostat was administered orally at the dosage of 40 mg/day three-times every week; dose adjustments for patients unable to tolerate the protocol-specified schedule were provided. The primary objective was to evaluate Panobinostat activity in terms of overall response (OR) according to the Cheson 1999 criteria; secondary objectives were: CR rate, time to response (TTR), progression-free survival (PFS), safety and feasibility of Panobinostat. We included evaluation of the impact of pharmacogenetics, immunohistochemical patterns and patient's specific gene expression and mutations as potential predictors of response to Panobinostat as explorative objectives. To this aim a pre-enrollment new tissue biopsy was mandatory. Results Thirty-five patients, 21 males (60%), were enrolled between June 2011 and March 2014. Clinical characteristics were: median age 73 (range 65-75), stage IV in 18 (55%), B-symptoms in 9 (28%), increased LDH in 24 (69%), high-intermediate or high International Prognostic Index (IPI) in 18 (51%). Patients received a median of 2 prior lines of therapy (range 1-4). At the end of induction phase, 7 responses (20%) were observed, including 4 CR (11%), while 28 patients (80%) discontinued treatment due to progressive disease (PD) in 21 (60%) or adverse events in 7 (20%). Median TTR in 9 responders was 2.6 months (range 1.8-12). With a median follow up of 6 months (range 1-34), the estimated 12 months PFS and OS were 27% and 30.5%, respectively. In univariate analysis, favourable IPI score and cutaneous involvement at enrollment showed a trend toward a higher ORR (p=0.007 and 0.061, respectively); pharmacogenetics, immunohistochemical and gene expression profile studies are still ongoing. No toxic deaths were reportewd; 18 patients died, 17 due to lymphoma progression and one for allogeneic transplant related complications, performed after PD. Grade 3-4 thrombocytopenia and neutropenia were the most common toxicities (in 29 (83%) and 12 (34%) patients, respectively), while grade 3-4 extra-hematological toxicity included diarrhoea in 4 (12%), infectious complications in 1 (3%) and supraventricular arrhythmia in 2 patients (6%). Conclusions The results of this study indicate that Panobinostat might be remarkably active in some patients with R/R DLBCL, showing durable CR. Feasibility was impaired by relevant hematological toxicity, mainly frequent and dose limiting grade 3-4 thrombocytopenia. Data that will be obtained from biological exploratory studies could hopefully be useful to better address the use of Panobinostat in peculiar subsets of patients. Figure 1 Figure 1.

Abstract Background: Patients with relapsed/ refractory diffuse large B-cell lymphoma (DLBCL) after- or not eligible for autologous stem cell transplantation (ASCT) have a poor prognosis. Treatment with salvage chemotherapy has generally been disappointing. In many centers in the Netherlands the oral PECC regimen is used for such patients. 90Y-ibritumomab tiuxetan (Zevalin®, Spectrum Pharmaceuticals) radioimmunotherapy (RIT) is clinically active as a single agent in relapsed DLBCL. We conducted a prospective multi-center phase II study evaluating salvage therapy with Rituximab (R)-PECC, in responsive patients followed by 90Y-ibritumomab tiuxetan consolidation. Methods: Adult patients with refractory/relapsed DLBCL, more than one year after or not eligible for ASCT, were treated with R-PECC (Prednisone 40 mg/m2 po D1-5; Etoposide 100 mg/m2 po D1-5; Chlorambucil 8 mg/m2 po D1-5; Lomustine 80 mg/m2 po D1 and Rituximab 375 mg/m2 iv D1) q 28 days for 4 cycles. Complete (CR) or partial responders (PR) received consolidation with a single dose 90Y-ibritumomab tiuxetan (15 MBq/kg, 0.4 mCi/kg). Response was evaluated according to the revised Cheson criteria (2007). Results: Between November 2008 and February 2012 62 patients were enrolled. Median age was 70 years (range, 45-82). Secondary IPI score was high-intermediate or high in 42% patients. All patients had received CHOP at first-line, 12 without rituximab. Prior therapies consisted of (R)-CHOP (65%), R-CHOP and R-DHAP/VIM (24%) or R-CHOP and R-DHAP/VIM plus ASCT (11%). Fourteen patients (23%) were refractory to the last prior therapy. After 4 cycles of R-PECC the overall response rate (ORR) was 31/62 (50%), with 14 of 62 (23%) patients achieving a CR and 17 of 62 (27%) achieving a PR, 13 of 62 (21%) patients had progressive disease. ORR of relapsed patients was significantly higher than that of patients refractory to their last prior treatment (63% vs 7%, p=0.0001). 29 of 31 responsive patients received consolidation with RIT. The remaining two patients with PR did not proceed to RIT because of one toxic death and one misinterpretation of the response. The ORR after the end of the entire treatment was 29% (23% CR, 6% PR), RIT consolidation improved the overall best response (from PR to CR) in 5 of the 17 PR pts after the R-PECC only regimen. The median follow-up time of patients still alive is 48 months (range, 0-67 months). The median response duration in the patients that received R-PECC only was 9 months (range 3-63 months). The median response duration in the patients that received RIT consolidation was 20 months (range 0-59 months). The failure free survival at 1 yr from start of RIT consolidation was 52% (95% CI=[33%,68%]) and the overall survival 62% (95% CI=[42%,77%]). There was one treatment related death, due to sepsis and pneumonia after the first R-PECC cycle. The R-PECC regimen was well tolerated by most patients. The most common grade 3 or 4 adverse events during R-PECC treatment were hematological toxicity (27%), infection (19%) and malaise (11%). Adverse events after RIT were primarily hematologic. Grade 3 to 4 trombocytopenia and neutropenia occurred in 8 patients (28%) and 5 patients (17%), respectively. Eight patients received platelet transfusions and 6 patients red blood cell transfusions. Conclusions: The R-PECC regimen shows good clinical activity in relapsed DLBCL patients. Its activity in refractory patients is low. This largely oral regimen provides patients not eligible for high-dose salvage treatment with a convenient treatment schedule with an acceptable safety profile. Consolidation with RIT was well tolerated and resulted in long response durations in half of the patients.

Diffuse large B-cell lymphoma (DLBCL) with extra nodal skeletal involvement is rare. It is currently unclear whether these lymphomas should be treated in the same manner as those without skeletal involvement. We retrospectively analyzed the impact of combining high-dose methotrexate (HD-MTX) with an anthracycline-based regimen and rituximab as first-line treatment in a cohort of 93 patients with DLBCL and skeletal involvement with long follow-up. Fifty patients (54%) received upfront HD-MTX for prophylaxis of CNS recurrence (high IPI score and/or epidural involvement) or because of skeletal involvement. After adjusting for age, ECOG, high LDH levels, and type of skeletal involvement, HD-MTX was associated with an improved PFS and OS (HR: 0.2, 95% CI: 0.1–0.3, p < 0.001 and HR: 0.1, 95% CI: 0.04–0.3, p < 0.001, respectively). Patients who received HD-MTX had significantly better 5-year PFS and OS (77% vs. 39%, p <0.001 and 83 vs. 58%, p < 0.001). Radiotherapy was associated with an improved 5-year PFS (74 vs. 48%, p = 0.02), whereas 5-year OS was not significantly different (79% vs. 66%, p = 0.09). A landmark analysis showed that autologous stem cell transplantation was not associated with improved PFS or OS. The combination of high-dose methotrexate and an anthracycline-based immunochemotherapy is associated with an improved outcome in patients with DLBCL and skeletal involvement and should be confirmed in prospective trials.

Abstract Although rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) is the standard treatment for patients with diffuse large B-cell lymphoma (DLBCL), ∼30% to 50% of patients are not cured by this treatment, depending on disease stage or prognostic index. Among patients for whom R-CHOP therapy fails, 20% suffer from primary refractory disease (progress during or right after treatment) whereas 30% relapse after achieving complete remission (CR). Currently, there is no good definition enabling us to identify these 2 groups upon diagnosis. Most of the refractory patients exhibit double-hit lymphoma (MYC-BCL2 rearrangement) or double-protein-expression lymphoma (MYC-BCL2 hyperexpression) which have a more aggressive clinical picture. New strategies are currently being explored to obtain better CR rates and fewer relapses. Although young relapsing patients are treated with high-dose therapy followed by autologous transplant, there is an unmet need for better salvage regimens in this setting. To prevent relapse, maintenance therapy with immunomodulatory agents such as lenalidomide is currently undergoing investigation. New drugs will most likely be introduced over the next few years and will probably be different for relapsing and refractory patients.
