Abstract Several studies (GELA 98.5, MInT) have demonstrated the benefit of combination rituximab (R) with chemotherapy to improve event free and overall survival in patients with DLBCL. We analyzed retrospectively the safety of combination R-CHOP for 6 cycles (rituximab 375 mg/m2 day 1; cyclophosphamide 750 mg/m2 day 1; doxorrubicin 50 mg./m2 day 1; vincristine 1.4 mg/m2 day 1 and prednisone 100 mg/m2 day 1 to 5) the tolerance and adverse effects. We evaluated the response (R), event free survival (EFS) and the overall survival (OS). Between March to December 2004, 28 patients with DLBCL were evaluated, 17 men and 11 women, with a median age 57 years old (range 28 – 84). They were IPI low 21,4 %, low - intermediate 25%, high - intermediate 35,7 % and high risk 17,9 %. Elevated LDH was present en 14 patients, bulky disease > 7 cm in 50% of cases. During the treatment they presented hematologic toxicity grade III 21,4 % and grade IV 25% of cases; 1 patient had anaphilactic reaction; 2 patients pneumonia; 1 patient sepsis; 4 patients neutropenia and fever; and gastric bleeding 1 patient. Response was achieve in 71,4 %: complete response (CR) in 57,1%, parcial (PR) in 14.3 %, and there was no response in 8 patients (28.6%). With follow up of 10 months (range 2 to 18.5) 15 patients were in CR 53,6%, 8 patients died, 7 of then primary no responders. Analyzed by IPI, 60% of CR in intermediate high and high was obtained. The R-CHOP combination is a feasible and safe treatment in our hospitals, and 71,4 % of response was obtained in all patients and 60% of CR in high risk group.

Abstract Background. Aggressive lymphomas accounts for about 80% of primary gastrointestinal non-Hodgkin`s lymphomas (PGIAL). In adults the most common type is diffuse large B-cell lymphoma (DLBCL). Burkitt lymphoma (BL) is rare and mainly affects children. R-CHOP chemotherapy can induce favorable result for localized-stage. But the presence of adverse factors (AF) and advanced stage decrease the efficacy of this therapy: 3-year progression-free survival (PFS) and overall survival (OS) are about 50% and 60% respectively. The optimal treatment strategy for this pts still remains unknown. Aim. Efficacy and safety assessment of the modified chemotherapy protocol NHL-BFM-90 (m NHL-BFM-90 and LB-M-04) in the treatment of the PGIAL with advanced stage and AF. Patients. 74 previously untreated pts with PGIAL underwent mNHL-BFM-90 or LB-M-04 treatment between January 2002 and December 2015; out of them, 45 pts - primary gastric lymphoma (PGL), 29 pts - primary intestinal lymphoma (PIL); median age 39 years (range 14-72); age ≥60 years 10 pts (13,5%); M\F=44\30; stage >I 58 pts (78,3%); B-symptoms 30 pts (40,5%); Bulky disease 28 pts (37,8%). Patients characteristics in groups presented in Table 1. In the PIL group compared with the PGL was predominance of male (M\F=20\9 versus 21\24), stage II-IV (89,6% versus 71%), high level of LDH (72% versus 49%), Bulky disease (55% versus 27%). In pts with high Ki-67 (>40%) FISH test on t(8;14) was performed. Burkitt`s lymphoma diagnosed in 5 pts (11%) with PGL and 9 pts (31%) with PIL. In the PIL group more than half (58,6%) pts received surgical treatment before chemotherapy, and only 2 pts (4,4%) - in the PGL group. Of the 74 pts, 60 (81%) were diagnosed with DLBCL, 14 (19%) - BL. All pts with DLBCL received treatment according to the mNHL-BFM-90 program (2 courses A and 2 courses B) that was modified in the following way: doxorubicin (50mg\m2) was added on the third day of course A. All patients with BL received treatment according to the LB-M-04 program (2 courses A and 2 courses C) that was modified in the following way: doxorubicin (50mg\m2) was added on the third day of course A, methotrexate was administered on the 1st day of course C at a dose 1500mg/m2 for 12 hours. No one received consolidation radiotherapy from both groups. Results. In DLBCL group the overall response rate (ORR) was 95%. Complete remission (CR) was achieved in 38 from 40 pts (95%) in PGL, and 17 from 20 pts (85%) PIL. With a median follow-up of 74 months (range, 1-156) disease-free and overall survival of 60 pts with DLBCL constituted 86.7% and 91,7%, respectively. In BL group all pts achieved CR and alive with no signs of progression with a median follow-up of 110 months (range, 62-154). Hematologic toxicity of grade 3 and 4 was observed in 80% of pts. Severe complications became the reason for subsequent switch to CHOP therapy after 2 courses in 6 pts with PGL DLBCL. There was no treatment-related mortality. Conclusions. The mNHL-BFM-90 and LB-M-04 demonstrated acceptable toxicity and high efficacy in patients with PGIAL. Burkett lymphoma is not rare in adults with PGIAL and detection of t(8;14) can improve treatment outcomes.

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 Introduction: R-miniCHOP is the standard chemotherapy for patients over 80 years (y) with DLBCL. In the LNH 03-7B trial, the 2-year overall survival was 58.9% [95% CI: 49.3-67.2%]. Grade III/IV toxicity and deaths occurred during the two first cycles mainly (Lancet Oncol. 2011 May;12(5):460-8). In order to improve overall survival (OS) rituximab (R) was replaced by Ofatumumab (OFA), a humanised anti-CD20 monoclonal antibody. In vitro data suggest that OFA induces more potent complement-mediated cytotoxicity than rituximab, and clinical data demonstrate activity of OF in rituximab-refractory lymphomas). In addition, to reduce early toxicity a pre-phase (PP) with vincristine and prednisone (P) was tested. Patients and methods: Patients older than 80 y with untreated CD20+ DLBCL, Ann Arbor stage I to IV, left ventricular ejection fraction > 50%, and a performance status (PS) of 0 to 4 were eligible. Patients received a PP with vincristine (1 mg TD D-7) and P (60 mg TD D-7 to D-4) before the first cycle of OF-miniCHOP. PP was followed by miniCHOP chemotherapy (cyclophosphamide: 400 mg/m² D1; doxorubicine: 25 mg/m² D1; vincristine: 1 mg total dose D1 and prednisolone 40 mg/m² by oral route from D1 to D5) plus OFA (1000 mg TD) every 21 days for 6 cycles. GCSF was optional. The primary objective was to evaluate the efficacy of PP OF-mini-CHOP as measured by the OS. Secondary endpoints were response rate (RR), progression free survival (PFS), event-free survival (EFS), disease-free survival (DFS) for complete responders and toxicities. Survival results are presented for all included patients on an intend-to-treat basis (n=120). Response to treatment was evaluated according to 1999 Cheson criteria. Results: From June 2010 to November 2011, One-hundred-twenty-patients (male, female) were included in 41 centers of the LYSA. The median age was 83 years (range 89-95). Seventy-seven percent of patients had a stage III/IV. LDH level was elevated in 58% of patients. Age-adjusted (aa) IPI was 2-3 in 57% of patients. One-hundred-twenty patients completed the PP, 107 the first three cycles and 89 received the whole regimen. For patients who started the first cycle, the mean relative Dose-Intensity during trial was 98%, 97% and 96 % for OFA, doxorubicine and cyclophosphamide respectively. Seventy-eight percent of patient received at least one injection of GCSF. The overall RR was 67.5%, including 35.8% of complete response and 20 % of unconfirmed complete response. At the time of this analysis, in September 2013, the median follow-up time was 26.6 months. The 2-year overall survival was 64.7% [95% CI: 55.3-72.7%]. The two-year PFS, EFS and DFS were 57.2% [95% CI: 47.7-65.6%], 53.1% [95% CI: 43.7-61.6%] and 66.6% [95% CI: 54.0-76.5%] respectively. Haematological toxicity was the most common side effect. Grade 3-4 neutropenia was observed in 20.8% of the patients and grade 3-4 thrombocytopenia in 1.7%. Seven patients (5.8%) experienced at least one episode of febrile neutropenia. Infusion reaction related to OFA was reported in 12.5% of patients. Prolonged hospitalization (> or = 10 days) was observed in 17 cases (14.1%) and mainly occurred during cycle 1 to cycle 3. Forty-five patients died during the treatment evenly distributed between lymphoma (62.2%), intercurrent and other causes (22.2%), and concurrent illness (15.6 %). No toxic death was reported. Six patients died during treatment (1 during PP, 4 during cycle 1 to cycle 3, 1 during cycle 4 to cycle 6) Thirty-nine patients died during follow-up. In univariate analysis, low aaIPI (0 /1) is the unique statistically significant prognostic factor of prolonged OS (OR 3.083, [1.458-6.517] CI95%). Instrumental Activities of Daily Living (IADL) score equal to 4 is associated with a longer PFS. By contrast, low Albuminemia level, undernutrition according to buzby index and high Charlson comorbidity index (CCI) were not predictive of survival. Conclusion: In DLCBL patients over 80 y, immunochemotherapy with PP OFA-mini-CHOP appears to be safe and effective, confirming that a substantial proportion of very old patients can be cured. The use of a PP seems to reduce the early death risk. OFA and PP seems to improve OS comparing with the previous reported data. The combination of a PP, monoclonal antibody against CD20 and miniCHOP can be the new standard regimen for DLBCL patients over 80 y.

Abstract Patients with relapsed chronic lymphocytic leukemia (CLL) and high-risk features, such as fludarabine refractoriness, complex karyotype, or abnormalities of chromosome 17p, experience poor outcomes after standard fludaradine-based regimens. Alemtuzumab is a chimeric CD52 monoclonal antibody with activity in CLL patients with fludarabine-refractory disease and 17p deletion. We report the outcome for 80 relapsed or refractory patients with CLL enrolled in a phase 2 study of cyclophosphamide, fludarabine, alemtuzumab, and rituximab (CFAR). All patients were assessed for response and progression according to the 1996 CLL-working group criteria. For the intention-to-treat analysis, the overall response rate was 65%, including 29% complete response. The estimated progression-free survival was 10.6 months and median overall survival was 16.7 months. Although we noted higher complete response in high-risk patients after CFAR compared with a similar population who had received fludarabine, cyclophosphamide, and rituximab as salvage therapy, there was no significant improvement in progression-free survival and overall survival appeared worse. CFAR was associated with a high rate of infectious complications with 37 patients (46%) experiencing a serious infection during therapy and 28% of evaluable patients experiencing late serious infections. Although CFAR produced good response rates in this highly pretreated high-risk group of patients, there was no benefit in survival outcomes.

Introduction: Little information is available on the outcomes of R-CHOP (rituximab with cyclophosphamide, doxorubicin, vincristine and prednisone) and R-CVP (rituximab with cyclophosphamide, vincristine and prednisone) in treatment of the elderly patients with non-Hodgkin lymphoma (NHL), especially in Vietnam. Material and methods: All patients were newly diagnosed with CD20-positive non-Hodgkin lymphoma (NHL) at Blood Transfusion and Hematology Hospital, Ho Chi Minh city (BTH) between 01/2013 and 01/2018 who were age 60 years or older at diagnosis. A retrospective analysis of these patients was perfomed. Results: Twenty-one Vietnamese patients (6 males and 15 females) were identified and the median age was 68.9 (range 60-80). Most of patients have comorbidities and intermediate-risk. The most common sign was lymphadenopathy (over 95%). The proportion of diffuse large B cell lymphoma (DLBCL) was highest (71%). The percentage of patients reaching complete response (CR) after six cycle of chemotherapy was 76.2%. The median follow-up was 26 months, event-free survival (EFS) was 60% and overall survival (OS) was 75%. Adverse effects of rituximab were unremarkable, treatment-related mortality accounted for less than 10%. There was no difference in drug toxicity between two regimens. Conclusions: R-CHOP, R-CVP yielded a good result and acceptable toxicity in treatment of elderly patients with non-Hodgkin lymphoma. In patients with known cardiac history, omission of anthracyclines is reasonable and R-CVP provides a competitive complete response rate.

Abstract Objective: Anthracycline-based chemotherapy induces 50%–70% of CR in patients with lymphoma, but only 30%–40% of long-term disease-free survival. Salvage chemotherapy with autologous stem cell rescue is required in patients with aggressive disease or never achieve CR with conventional chemotherapy,but the relapsed rate is still high. The purpose of this study was to evaluate radiotherapy post autologous stem cell transplantation in such group of patients. Methods: 15 patients who underwent autologous stem cell transplantation during 1992–1998 were enrolled in this study. Conditioning regimen was CBV (cyclophosphomide + carmustine + etoposide). Radiotherapy was started on day +50(31–90). All patients were followed up until January 2005. Kaplan-Mier survival analysis was made by using SPSS10.0 software. Results: There were 14 patients with non-Hodgkin lymphoma and 1 with Hodgkin disease enrolled. Male:female=11:4. Median age was 40 (30–64). At least 6 cycles of induction chemotherapy were given before transplantation. There were 3 patients in progression disease, 1 in stable disease, and 11 in partial remission before transplantation. Three patients received total lymph node irradiation (TLI). Seven patients received TBI(200cGY)+involved field irradiation therapy(IFIT). Five were treated with IFIT. All patients acheaved complete response(including 1 CRu) after radiotherapy. Three patients relapsed. One patient treated with TBI+IFIT relapsed at 6 months later. Two patients treated with IFIT relapsed at 8 and 36 months later respectively. The mean disease-free survival and overall survival were 10.84(SD1.37,95%CI) years and 11.89(SD1.35,95%CI) years respectively. The estimatrd 10-year disease-free survival and Overall survival were both 73%. One patient developed AML at 86 month. Grade III–IV hematologic toxicity was seen in 2 patients. Conclusions: Post ASCT radiotherapy is safe and tolerated. Relaps rate is low. Patients who received TLI or TBI+IFIT seem to have better outcome than that received IFIT only.

Abstract MCL has a poor outcome with current non-intense therapies. We present an update of our results utilizing an intense chemotherapy regimen comprising fractionated cyclophosphamide, doxorubicin, vincristine and dexamethasone to which rituximab has been added (R-HyperCVAD, one cycle), alternating with rituximab and high dose methotrexate/cytarabine (R-MA, one cycle) for a total of 6–8 cycles (J Clin Oncol 2006 Feb 1;24(4):724). Treatment was started at most within 2 months from the initial evaluation. Overall survival (OS) was defined as the time from start of treatment until recurrence or death from any cause. Failure-free survival (FFS) was defined as the time from start of treatment until recurrence or death from toxicity or death from treatment-related malignancy. Of 97 consecutive evaluable patients, 87% achieved a complete response (CR) or unconfirmed CR after 6 cycles and did not receive additional therapy. With a median follow up on 84 months (7 years), the overall survival and failure-free survival at 7 years was 60% and 43%, respectively. Among patients 65 years of age or younger, the 7-year OS and FFS was 68% and 52%, respectively. Important prognostic variables included age (65 yrs or less vs > 65 yrs; initial serum B2 microglobulin 3 or less mg/dL vs > 3); and initial serum lactate dehydrogenase (normal vs > normal). Further subset analysis will be presented at the meeting. Figure Figure

Abstract Abstract 1772 Background: Hodgkin Lymphoma (HL) is the most curable type of Lymphoma with an overall survival at 5 years of 80%. ABVD can be considered as gold standard for first line treatment for all stages of HL. Dividing patients (pts.) in different prognostic groups has aimed to reduce chemo and radio toxicity in those patients with good prognosis. A negative PET-CT, either early during treatment of ABVD or after completion of it, has shown to be a powerful prognostic tool (Hutchings: Blood 2006; Gallamini: Haematologica 2006). Our cooperative group has an experience with 584 patients with HL in early or advanced stage treated with 3 or 6 cycles of ABVD plus involved field radiotherapy with a complete remission (CR) of 91% and an event free survival (EFS) and overall survival (OS) at 60 months of 79% and 95%.(S Pavlovsky, Clin Lymp My & Leuk, 2010). Aims: Test the efficacy of treatment to all stages of HL adjusted to PET-CT results after 3 cycles of ABVD. Evaluate the outcome of pts. who have a negative PET-CT after 3 cycles of ABVD and receive no further treatment. Intensify therapy only in pts. who have persistent hyper metabolic lesions in PET-CT after 3 cycles of ABVD. Method: Since October 2005, 198 newly diagnosed pts. with HL have been included in a prospective multicenter trial. Initially all patients received 3 cycles of ABVD. After the third cycle, pts. were evaluated with a PET-CT. Those pts. who achieved CR with a negative PET-CT, received no further treatment. Those with more than 50% of anatomic reduction of initial masses but persistent hyper metabolic lesions by PET-TC after 3 ABVD were considered in partial remission (PR) and completed 6 cycles of ABVD and radiotherapy (RT) on PET-CT positive areas. Those patients with less than PR after 3 cycles of ABVD received ESHAP and if CR, high doses of chemotherapy and an autologous stem cell transplant (ASCT). All patients were re-evaluated at the end of treatment. The median follow up is of 30 months (3-62). Results: One hundred and seventy three patients completed three cycles of ABVD followed by a PET-CT. The median age at diagnosis was 29 years. One hundred and thirty-six (79%) had localized stage (I-II) at diagnosis and 37 (21%) presented with advanced stage (III-IV). Of 155 pts. 77 (50%) pts had IPS 0–1, 66 (43%) had IPS 2–3 and 12 (8%) had IPS 4–5. Twenty six (17%) pts. had bulky disease at diagnosis. One hundred and thirty-seven (79%) pts. achieved CR with negative PET-CT after 3 cycles of ABVD. Thirty-six (21%) were PET-CT positive, of them 32 pts achieved PR and completed a total of 6 cycles of ABVD plus RT in hyper metabolic lesions. Twenty five achieved CR (72%), 5 persisted with PR and 2 died of progressive disease. Four pts showed progressive disease (PD) after 3 ABVD and received ESHAP and ASCT, 2 achieved and remained in CR, 1 is in PR and 1 died of progressive disease. Of 173 pts who completed treatment with ABVD × 3 cycles, ABVD × 6 cycles plus RT on PET-TC positive areas or ESHAP plus ASCT, 164 pts (95%) achieved CR. Of these 164 pts., 14 pts (8%) relapsed. The EFS and OS at 36 months is 83% and 97% respectively. Patients with early negative PET-TC have an event-free survival of 87% compared to 62% (P=0,001) for pts with early positive PET CT. The OS at 36 months was 100% versus 86% respectively (<0.001). Conclusion: Treating patients with ABVD, evaluating response after 3 cycles with PET-CT, and adapting further therapy, leads to a high rate of CR avoiding more aggressive chemotherapy and radiotherapy. Three courses of ABVD without RT are adequate in patients with early CR defined by negative PET-CT. In early positive PET-CT it is possible to intensify therapy improving the otherwise bad prognosis; more aggressive treatment might also be suitable. These results need to be confirmed by a larger group of patients and a longer follow-up. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 1782 Background: Chemo immunotherapy (R-CHOP) has improved outcomes of both GC (germinal center) and ABC (activated B-cell) subtypes of DLBCL. However outcomes in DLBCL patients treated with R-CHOP with ABC subtype (vs. GC) and/or with poor-risk features (High IPI, high Ki-67) remain inferior. These patients might benefit from more dose-intensive or high-dose therapy approaches. In our practice at The John Theurer Cancer Center, we have employed a risk-adaptive strategy with R-HCVAD to treat patients with DLBCL with aggressive features. Methods: Utilizing Kaplan Meier (KM) survival and Cox regression analyses, we conducted a retrospective cohort study to describe the outcome of patients treated with R-HCVAD in the 1st-line setting with the following high-risk features: high Ki-67 (MIB-1), high IPI, multiple extra-nodal (EN) sites, bulky disease or immunohistochemistry (IHC) staining patterns (GC vs. non GC by Hans’ model). The primary study endpoints were PFS and OS. The proportional hazards assumption was met for this analysis. Results: 45 patients (median age 57, range 34–71 yrs) with newly diagnosed DLBCL treated with R-HCVAD (median 6 cycles, range 1–8) were available for this analysis, representing 1010 total months of follow up at-risk. Baseline characteristics included: stage III-IV (90%), IPI ≥ 3 (52%), median Ki-67 (80%, range 10–100%), median EN sites (2), non-GC subtype (34%), bone marrow (BM) involvement (38%), EBER positive (14%), HIV negative (100%). With 17 months (range 9–64 months) median follow up, median OS and PFS (graph) are not yet reached. 2-yr PFS and OS were 80% (95% CI 61–91%) and 78% (95% CI 61–88%) respectively. In Cox regression analysis, survival outcomes were not adversely affected by: patient age > 60 (HR .8, p=.18), LDH > ULN (HR 2.3, p=.3), non-GC IHC pattern (HR .5, p=.5), BM involvement (HR 1.9, p=.4), Ki-67 ≥ 80% (HR 1.7, p=.6) or EN sites ≥ 2 (HR 4.7, p=.15). Conclusions: This analysis represents the largest reported cohort of DLBCL patients treated with R-HCVAD. These data suggest that R-HCVAD can overcome traditional poor-risk features such as high IPI, high Ki-67 and non-GC IHC pattern. Future work will focus on identifying molecular markers for failure in DLBCL patients treated with dose-intensive regimens. A randomized trial comparing R-HCVAD to R-CHOP in selected high-risk patients is warranted. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 2681 Background: Despite recent advances, the 5 year overall survival for patients with high risk diffuse large B cell lymphoma (DLBCL) is approximately 50% and there is still no known cure for patients with mantle cell lymphoma (MCL). This phase II study of multimodal dose dense therapy evaluated 2 courses of dose intense chemotherapy followed by radioimmunotherapy (RIT) consolidation in patients with previously untreated, mantle cell or high/high intermediate (int) risk aggressive B cell lymphoma. Aim: To evaluate the efficacy and safety of dose intense/dose dense, multimodal chemo-immunotherapy combined with RIT. Methods: Patients with untreated MCL or high int/high risk DLBCL were enrolled. Treatment regimen involved 3 phases of therapy: induction 1, induction 2 and consolidation with RIT (Table 1). Induction 2 occurred approximately 5 weeks after induction 1 and RIT was given 12–24 weeks after rituximab was completed. Patients were evaluated after each treatment phase and those with stable disease (SD) or better and blood count recovery could proceed to the next phase of therapy. Results: Thirty nine patients (pts) with high/high int risk DLBCL (n=25) or MCL (n=14) were enrolled. The median age was 60 years (range 21–80). Toxicity: Common, anticipated toxicities in the induction phases were thrombocytopenia, neutropenia, nausea, fatigue, and anemia. During Ind1 (n=39), grade (gr) III mucositis occurred in 13 pts (33%) and febrile neutropenia (FN) in 31 (79%). Three pts did not proceed to Ind2 due to death (1 candidemia, 1 septic knee prosthesis, 1 from complications of colectomy for prolonged diverticulitis after count recovery) and 2 withdrew to pursue less intense chemotherapy. During Ind2 (n=34) gr III mucositis occurred in 12pts (35%) and FN in 24 (67%). Two pts had gr III/IV cerebellar toxicity that was disabling in 1 pt. Of the 34 pts who received the Ind2, 9 did not receive RIT due to progressive disease (PD) (4), prolonged cytopenias (4), or diagnosis of pancreatic cancer (1). Twenty five pts received RIT and 3 (12%) had FN, 20 (80%) had gr III/IV neutropenia, 23 (92%) had gr III/IV thrombocytopenia, 1 pt died from bacteremia. Two pts developed myelodysplasia 21 and 48 months after starting therapy. Response: Pts were evaluated for response after Ind1, Ind2 and RIT. 38/39 pts were evaluable for response, with 1 pt withdrawing prior to assessment. The pts who died prior to response evaluation were counted as non-responders. The best overall response rate (ORR) was 95% (36/38) with a complete response rate (CR) of 84% (32/38). See tables 2 and 3 for more detailed response data by phase of treatment and disease type. After a median follow up of 17.2 months, 30 pts (77%) are alive (see figure). The median overall survival for MCL has not been reached and is 36.5 months for DLBCL. Deaths were from Hodgkin lymphoma (1), infection (3), DLBCL (2), complications of surgery (1), MCL (2). The median progression free survival is 36.5 months with 11/14 (79%) MCL and 14/25 (56%) DLBCL pts alive and in continued CR. Conclusion: The combination of dose dense, dose intense chemotherapy, monoclonal antibody, and RIT demonstrates considerable efficacy, despite expected toxicity, in high risk DLBCL and MCL pts. The response rates seen in this study are higher than expected from standard R-CHOP in this pt population. Further follow up to determine impact on OS and long term complications will be required to confirm these promising outcomes. Disclosures: Beaven: Glaxo Smith Kline: Family Member Employed by GSK.
