Abstract Abstract 2036 Background: Stem cell transplantation (SCT) is a common indication for patients with Non-Hodgkin lymphoma (NHL). Auto-SCT is recommended for patients with relapsed NHL or as consolidative therapy in first remission. Allo-SCT is reserved for pts with either relapsed or primary refractory disease. The outcomes of these pts in large prospective studies are lacking and current recommendations and timing of selection of auto vs. allo-SCT are influenced by variety of factors including physician bias. Transplant outcomes of auto or allo-SCT have not been elucidated as a single cohort. Methods: We report a retrospective analysis of 270 pts with NHL who underwent auto-SCT or allo-SCT between January 2000- December 2010 after obtaining institutional IRB approval. Data were analyzed using SPSS.19. Results: Of the 270 pts, 238 patients underwent SCT for B-cell lymphoma (178 auto, 60 allo-SCT), and 32 for T-cell lymphoma (21 auto and 11 allo-SCT). Fifteen pts (6%) received prior auto-SCT. The median age of transplant was 52 years for the entire group. For those who underwent allo-SCT, median age was 47 (range 22–65 yrs) and 54 yrs (range 22–77) for auto-SCT. One hundred seventy (62%) were male. Majority of pts (76%) had advanced stage disease (stages III and IV). Fifty four (20%) received radiation therapy either before or after transplantation. The median number of prior regimens for allo-SCT were 3 (range 1–5) and 2 for auto-SCT (range 1 to 4). Within the allo-SCT group (n=71), 45 received matched-related donor transplants, and 26 unrelated donor transplants; majority of pts (n=47) received reduced intensity conditioning regimen. The auto-SCT group predominantly received CBV as their conditioning regimen. Median time from diagnosis to allo-SCT or auto-SCT was 1.4 yrs (range 0.32–13.1 yrs) and 1.69 (range 0.38–13.7 yrs), respectively. The median follow up time for the entire cohort was 6.2 yrs. The overall survival (OS) rates for the B- cell and T-cell NHL were 58% and 50% respectively (allo-SCT 51% vs. 54% for B and T-cell NHL, and auto-SCT 60% vs. 47% for B and T-cell lymphoma, respectively) (p=0.26). Within the allo-SCT group the relapse and non-relapse mortalities were 45% and 16%, respectively. In the auto-SCT group, the relapse and non-relapse mortality were 46% and 7% respectively. In B-cell lymphoma the relapse rate was 48% and 45% for auto and allo-SCT respectively (p=0.80). In T-cell lymphoma the relapse rate was 40% and 45% for auto and allo-SCT (p=0.67). Multivariate analysis of pts receiving auto vs. allo-SCT in NHL will be presented. Conclusions: We conclude that in this highly selected patient population with otherwise minimal comorbidities but chemo-sensitive aggressive lymphomas, about 50% of patients achieve long term survival after either an auto or allo-SCT approach. Despite recent evidence, there are intricate difficulties in patient selection for allo vs. auto-SCT and outcome of either approach is not satisfactory. Post transplant relapse is the most common cause of post-SCT failure. Tandem auto followed by allo-SCT and maintenance strategies need to be explored. We propose a larger prospective analysis on transplant outcomes in both B and T-cell lymphoma and improve strategies to prevent relapses after SCT. Disclosures: No relevant conflicts of interest to declare.

Abstract Background: In order to study the CXCR4 expression with 68Ga-Pentixafor PET in different types of non-Hodgkin lymphoma, we performed a retrospective study to describe the 68Ga-Pentixafor PET/CT imaging in a spectrum of lymphomas and to compare it with 18F-FDG PET/CT. Results: Twenty-seven patients with newly diagnosed non-Hodgkin lymphoma were recruited retrospectively. 68Ga-Pentixafor PET showed increased radioactivity in lymphoplasmacytic lymphoma (n = 8), marginal zone lymphoma (n = 4), diffuse large B cell lymphoma (n = 3), follicular lymphoma (n = 2), mantle cell lymphoma (n = 1), unclassified indolent B cell lymphoma (n = 3) and enteropathy associated T cell lymphoma (n = 3). However, peripheral T cell lymphoma, not otherwise specified (n = 1), and NK/T cell lymphoma (n = 2) were not avid for 68Ga-Pentixafor. In comparison to 18F-FDG PET, 68Ga-Pentixafor PET demonstrated more extensive disease and higher radioactivity in lymphoplasmacytic lymphoma and marginal zone lymphoma. Conclusion: CXCR4 expression varies in different types of non-Hodgkin lymphoma. Overexpression of CXCR4 was detected with 68Ga-Pentixafor PET/CT in lymphoplasmacytic lymphoma, marginal zone lymphoma, diffuse large B cell lymphoma, follicular lymphoma, mantle cell lymphoma, unclassified indolent B cell lymphoma, and enteropathy associated T cell lymphoma.

T Cell Lymphomas

In this review, we examine the genomic landscapes of lymphomas that arise from B, T, and natural killer cells. Lymphomas represent a striking spectrum of clinical behaviors. Although some lymphomas are curable with standard therapy, the majority of the affected patients succumb to their disease. Here, the genetic underpinnings of these heterogeneous entities are reviewed. We consider B-cell lymphomas, including Burkitt lymphoma, diffuse large B-cell lymphoma, Hodgkin lymphoma, and primary mediastinal B-cell lymphoma. We also examine T-cell lymphomas, including anaplastic large-cell lymphoma, angioimmunoblastic T-cell lymphoma, cutaneous T-cell lymphoma, adult T-cell leukemia/lymphoma, and other peripheral T-cell lymphomas. Together, these malignancies make up most lymphomas diagnosed around the world. Genomic technologies, including microarrays and next-generation sequencing, have enabled a better understanding of the molecular underpinnings of these cancers. We describe the broad genomics findings that characterize these lymphoma types and discuss new therapeutic opportunities that arise from these findings.

Abstract Introduction CHOP chemotherapy has been accepted as the standard treatment for patients with non-Hodgkin lymphoma (NHL), but in some histological or clinical subtypes the results are not satisfactory. We have shown the efficacy and safety of high-dose biweekly THP-COP with G-CSF support (HDBW-TCOP(G)) for NHL. In this regimen, we choose pirarubicin in stead of doxorubicin because it was proven high efficacy against NHL and the lower toxicity than doxorubicin. Recently, the combination of rituximab and standard CHOP has been shown to have a synergistic effect for NHL. We performed a phase II multicentric clinical study to assessed the feasibility and toxicity of the combination chemotherapy of rituximab and HDBW-TCOP(G) (HDBW-R-TCOP(G)) compared with those of HDBW-TCOP(G). Patients and methods Between August 1998 and December 2004, Forty-one Japanese patients with previously untreated NHL from whom informed consent was obtained were included in this study. Median age was 45 (range 19–63) years. There were 19 males and 22 females. According to WHO-classification diagnoses, histological subtypes included follicular lymphoma (FL) 15(37%); nodal marginal zone B-cell lymphoma (NMZBCL) 2(5%); mantle cell lymphoma (MCL) 3(7%); anaplastic large cell lymphoma (ALCL) 1(2%), diffuse large B-cell lymphoma (DLBCL) 18(44%); peripheral T-cell lymphoma (PTCL) 1(2%), angioimmunoblastic T-cell lymphoma (AILT) 1(2%). Of 41 patients, one patient was stage 1, stage 2, 11 stage 3 and 16 stage 4. International prognostic index (IPI) included L 6; LI 22; HI 7; H 6. HDBW-TCOP(G) consisted of pirarubicin 70 mg/m2 on day 1; cyclophosphamide 1000 mg/m2 on day 1; vincristine 1.4 mg/m2 on day 1; predonisolone 50 mg/m2 orally from day 1 to 5; lenograstim 2.0 μg/kg/day from day 3. Fifteen patients who enrolled after rituximab was approved in Japan received therapy combined HDBW-TCOP(G) with rituximab 375mg/ m2 on day -2 (HDBW-R-TCOP(G)). Six cycles were administered at intervals of two weeks. Results Of the 41 patients treated, 32 (78.0%) achieved a complete remission (CR) and nine (22.0%) achieved a partial remission (PR), for an overall response rate of 100%. After median follow-up of 36 months (range 2.9– 81.8), progression free survival (PFS) and overall survival (OS) were 68.2% and 97.5%, respectively. PFS was 90.9% for HDBW-R-TCOP(G), and 69.5% for HDBW-TCOP(G), but no significant differences was found among two regimen. There was no significant difference in the PFS and OS between aggressive and indolent histological subtypes. 76% of patients developed Grade4 leukopenia (according to NCI criteria) but no patients experienced febrile neutropenia. 15% of patients developed G4 anemia and 17% of patients G4 thrombocytopenia. Other adverse effects were minimal. Conclusion Both HDBW-TCOP(G) and HDBW-R-TCOP(G) are feasible for NHL with acceptable toxicity. The excellent result suggests they are effective for aggressive NHL patients with poor prognostic factors and advanced stage indolent NHL.

Abstract Mature peripheral T/Natural killer (NK)-cell neoplasms represent 10–15% of non-Hodgkin’s lymphoma (NHL) in adults. T/NK-NHL have a worst prognosis compared with B-cell lymphomas. Allogeneic stem cell transplantation (allo-SCT) is an attractive option for these patients. On behalf of the SFGM-TC group, we conducted a retrospective analysis and included seventy-seven T/NK-cell lymphoma patients. Diagnosis were: ALCL (n=27), Peripheral T-cell Lymphoma Not-Otherwise Specified (PTCL-NOS) (n=27), Angioimmunoblastic T-cell Lymphoma (AITL) (n= 11), Hepatosplenic g/d lymphoma (HSL) (n=3), T-cell granular lymphocytic leukemia (T-GLL) (n=1), nasal NK/T-cell lymphoma (nasal-NK/L) (n=3) case or non-nasal NK/T-cell lymphoma (non nasal-NK/L) (n=2), enteropathy-Type T-cell (n=1) and HTLV-1 lymphoma (n=2). Fifty-seven patients received myeloablative conditioning regimen prior allo-SCT. Donors were HLA-matched in 70 cases and related in 60 cases. Patients status at the time of allo-SCT was CR in 31 cases, PR in 26 cases and SD/PD in other cases. Five-year toxicity-related mortality (TRM) rate was 34%. Major cause of death was infection. Five-year OS and EFS rates were 57% and 53.3%, respectively. In a multivariate analysis, chemoresistance disease (SD, refractory or progressing disease at the time of allo-SCT and aGVHD grade III/IV were the only adverse prognostic factors for OS (p= 0.027 and p=0.033, respectively). Disease status at transplantation influenced EFS (p= 0.0032) and a HLA-mismatched donor increased TRM (p= 0.0386). A plateau was reached after one and a half year after allo-SCT. Only 5 out of 59 patients in CR after allo-SCT experienced a relapse. The 5-year OS rate for chemo-resistant patients was also encouraging. These patients were not curable with conventional approaches and near of one third have taken advantage of allo-SCT. Furthermore, two patients received DLI at relapse and they both reached a second durable CR. Taken together, this suggests that there is a graft versus T-/NK-lymphoma effect which may play a role in the curative potential of allo-SCT. we conclude that randomized clinical trials comparing allo-SCT versus conventional chemotherapy upfront for PTCL, aggressive AITL or histopathological subtypes (HSL, HTLV-1 lymphomas) have to be encouraged.

Pathologic Classification

Abstract One hundred and nineteen children with non-Hodgkin lymphoma were treated between February 2003 and December 2006 in Beijing Children’s Hospital on BCH-2003-NHL protocol. The diagnosis was made by histopathology of the biopsied tissue and/or bone marrow, and disease was classified according to WHO-2001 pathologic classification. We applied modified LMB89 protocol to cases with B-cell lymphoma; modified BFM90-ALL protocol for lymphoblastic lymphoma and cutaneous T-cell/NK cell lymphoma; and modified BFM90-ALCL protocol for anaplastic large-cell lymphoma (ALCL). There were 50 cases (42%) of B cell lymphoma including 32 cases of Burkitt¡’s lymphoma, 10 cases of Burkitt-like lymphoma and 8 cases of diffuse large B cell lymphoma; 44 cases (37%) of lymphoblastic lymphoma; 19 cases (16%) of ALCL; and 6 cases (5%) of cutaneous T-cell/NK cell lymphoma. The 85 boys and 34 girls (ratio, 2.5:1) ranged in age from 2 to 15 years (median, 7.8 years) at diagnosis. B cell lymphoma typically presented as abdomen mass and acute abdomen; nasopharynx and tonsil were also common sites of involvement. Lymphoblastic lymphoma generally presented with mediastinal mass and bone marrow involvement. There was no typical presentation for ALCL. According to the St. Jude staging system, 19 cases had stage I–II, and 94 cases stage III–VI diseases (exclude 6 cases of cutaneous T-cell/NK cell lymphoma). Seven cases had CNS involvement and 25 cases involved bone marrow. The treatment duration was 2 to 8 months for B-cell lymphoma, 2.5 to 3 years for lymphoblastic lymphoma and 1 to 1.5 years for ALCL. The follow-up rate was 100% and median observation period was 23 months. The overall survival (OS) at 3 years was 90.7% and the 3-year event-free survival (EFS) estimate was 82.3%. For B-cell lymphoma, 3-year OS was 88.68% and 3-year EFS was 81.8%. For lymphoblastoma lymphoma, the rates were 89.3% and 69.4%, respectively. All cases of ALCL are alive with on undergoing treatment for relapse. Patients with ALCL achieved the best 3-year OS (100%) and had 3-year EFS of 94.2%. Grade 3 or 4 bone marrow suppression occurred in 97.5% of patients with B-cell lymphoma, 100% of those with lymphoblastic lymphoma and 89.5% of cases with ALCL. As of to date, 11 patients have died, the causes of death include infection (n=4), abandonment of therapy (n=6) and relapse (n=1). Univarate analysis showed that stage IV disease, failure to achieve complete remission after 3 months of treatment, and bulky mass are were associated with poor prognosis £all P values <0.05£©. In summary, we have achieved excellent treatment results using modified international protocols. Infection and financial problem remained the main reasons of treatment failure.

e19523 Background: Primary intestinal non-Hodgkin lymphoma (NHL) is a rare but heterogeneous disease in East Asia. However, the benefit of multidisciplinary treatment is still in debate. We characterized the clinicopathologic features, and treatment outcome in a single institute database. Methods: Patients with NHL primarily involving the intestine and treated during 1992 to 2008 were selected from the Cancer Registry of National Taiwan University Hospital. The medical charts and pathology records were carefully reviewed. Results: There were 64 men and 17 women with a median age of 51.5 years. Sites involved were colon/rectum (53.2%), small intestine (30.9%), and duodenum (13%). Histopathology subclassification included diffuse large B-cell lymphoma (DLBCL) (61.7%), mucosa-associated lymphoid tissue lymphoma (11.1%), Burkitt’s lymphoma (8.6%), T cell lymphoma (6.2%), follicular lymphoma (2.5%), mantle cell lymphoma (1.2 %) and others (8.6%). Ann Arbor stage IE to IIE accounted for 61.7%, whereas lower IPI score (1-2) were 54.8%. Among them, 27 patients received surgery plus chemotherapy, 60 received chemotherapy, and 4 had radiotherapy. At average follow-up of 48.7 months, 5 year survival rate were 59%, 43% and 51% for colon/rectum, small intestine, and duodenal NHL, respectively (p=0.45). Surgery plus chemotherapy versus chemotherapy alone showed no survival benefit in lower IPI group (p=0.682) nor in higher IPI (3-5) group (p=0.939). A trend of better median overall survival (mOS) was seen in rituximab group than in non-rituximab group in DLBCL subtypes (not reach vs. 39.8mo, p=0.075). In univariate analysis, stage III/IV (p=0.008), IPI score greater than 2 (p=0.011), and T cell histology (p<0.001) were significant prognostic factors for poor OS. In multivariate analysis, T cell histology remained the independent prognostic factor for inferior OS (p<0.001, HR: 20.3, 95% CI: 5.1-80.4). Conclusions: Although B cell NHL was the majority of primary intestinal NHL in our institute, T cell histology has significant inferior survival. Chemotherapy is still the backbone of treatment for primary intestinal NHL. The benefit of rituximab to intestinal DLBCL needs further confirmation.

Background: Geographic variations with regard to incidence and histological subtypes are known to occur in Non-Hodgkin lymphoma (NHL). This study was aimed to see the incidence and subtypes of NHL in a group of Bangladeshi population.Methods: This cross sectional study was carried out in Armed Forces Institute of Pathology (AFIP) Bangladesh, from 1st April 2017 to 31st March 2018. All nodal and extranodal tissues which were morphologically diagnosed as NHL were included in the study and immunohistochemistry was done for sub-classification according to WHO classification 2016. Bone marrow trephine biopsy samples were excluded.Results: Total cases: 106, mean age: 48.5 years ± 18.5 (range 2Y 9 M –82 years), male-female ratio: 2.2:1. Total subject of B cell Lymphoma (BNHL): 83 (78.3%) and T cell lymphoma (TNHL): 23 (21.7%). Among BNHL, total subjects of diffuse large B cell lymphoma (DLBCL) 50 (60%), follicular lymphoma 9 (11%), marginal zone lymphoma 8 (10%), small cell lymphoma and mantle cell lymphoma 5 (6%) each, Burkitt lymphoma 4 (5%) and B cell lymphoblastic lymphoma 2 (1.89%) in number. Among TNHL peripheral T-cell lymphoma NOS 11 (48%), anaplastic large cell lymphoma (ALCL) 5 (22%), T cell lymphoblastic lymphoma 4 (17%), and angio-immunoblastic T cell lymphoma 3 (13%) in number. Among 5 ALCL, 4 ALK positive and 1 ALK negative. Number of primary extra-nodal NHL were 29 (27%) with most common involved organ system being GIT and most common histological subtype being DLBCL.Conclusion: Quite similar pattern of age range with mean age, male to female ratio, subtypes and extra nodal NHL distribution prevailing in our subcontinent is found in our population with subtle increased incidence of TNHL indicating the necessity of further large epidemiological study.Birdem Med J 2018; 8(3): 215-222

7543 Background: Brentuximab vedotin (BV), an antibody-drug conjugate targeting CD30, has been evaluated in multiple trials in patients (pts) with peripheral T-cell lymphoma (PTCL), cutaneous T-cell lymphoma (CTCL), or B-cell lymphoma. We examined the ability of CD30 expression level to predict response to BV across these patient populations. Methods: Data were integrated from 275 pts with PTCL, CTCL, and B-cell lymphoma treated with BV from 5 prospective clinical trials. Study SGN35-012 evaluated BV plus rituximab or BV monotherapy in pts with relapsed/refractory non-Hodgkin lymphoma. The ALCANZA study compared BV to physician’s choice of methotrexate or bexarotene in pts with mycosis fungoides (MF) or primary cutaneous anaplastic large cell lymphoma (pcALCL). Three investigator-sponsored trials evaluated BV monotherapy in pts with relapsed PTCL, MF, and pcALCL (35-IST-030, 35-IST-001, 35-IST-002). Exploratory analyses were conducted to examine the relationship between CD30 expression and objective response rate (ORR) for pts with CD30 expression ≥10%, <10%, or undetectable (0%) by IHC (malignant cells or lymphoid infiltrate; local review). Results: 143 pts had tumors with CD30 <10%, including 58/143 with undetectable CD30. Activity with BV was observed at all levels of CD30 expression, including CD30=0 (Table). Analysis of the interaction between CD30 and duration of response is ongoing and will be presented in the final poster. ORR by CD30 expression, n/N (%). Clinical trial information: NCT01421667, NCT02588651, NCT01578499, NCT01352520, NCT01396070. Conclusions: CD30 expression levels ≥10%, <10%, or undetectable did not predict response to BV in a range of CD30-expressing lymphomas: Clinical responses occurred in pts with CD30 low and CD30 undetectable lymphomas. Limitations of IHC, the dynamic nature and heterogeneity of cell-surface CD30 expression, and multiple mechanisms of action of BV may all contribute to this observation.[Table: see text]

Risk Of Death

Abstract Autologous Stem Cell Transplantation (ASCT) is standard of care in relapsed diffuse large B-cell lymphoma(DLBCL) and other lymphoproliferative disorders (relapsed Hodgkin´s disease, mantle cell lymphoma (MCL) or T-cell lymphoma). BCNU, Etoposide, Ara-C, Melphalan(BEAM) is a standard conditioning regimen, but BCNU is known to be associated with interstitial pneumonia (range 2 to 20%) and an increased risk of death compared with other regimens. Therefore a less toxic conditioning protocol might improve the results in lymphoma patients. Bendamustineshowed promising results in B- and T-cell lymphoma and dose escalation is safe and feasible. Here we report promising results with bendamustinereplacing BCNU in the BEAM regimen described as Benda-EAM, previously published in a phase two dose finding study (Visani, Blood 2011). Fourty-one patients with Hodgkin´s (HL)(n=9) or Non-Hodgkin (n=32) lymphoma were consecutively treated with Benda-EAM (bendamustineon two consecutive days at a dose of 200 mg/m2 per day). Eleven patients were diagnosed with DLBCL, ten patients with MCL, six patients with follicular lymphoma (FL), three patients with T-cell lymphoma (TCL) and two patients with greyzone lymphoma (GZL). Twenty-seven patients were male and fourteen female with a median age of 52 years (range 22-71) and 25% were above the age of sixty. The median lines of previous therapies were 2 (range: 1-4). All patients had chemosensitive disease and before transplantation 34 patients (83%) were in complete (CR) and 7 (17%) in partial remission (PR). A median number of 4,20*106 CD34+ cells/kg (range: 1,60-13,30) were infused. All patients showed engraftment with a median time to achieve an absolute neutrophil count > 1*109/L of 10 days (range 8-13) and to platelets >20*109/L of 12 days (range 7-110). The median time of fever was 5 days (range: 0-15). The most common grade 3 and 4 toxicity during the whole treatment period were diarrhea (n=10), mucositis (n=7), infections (n=9) and febrile neutropenia (n=6), followedby nausea (n=4) and cardiologic toxicities (n=3). There were no pulmonary toxicities observed and no transplant related mortality occurred. After a median follow-up of 37 months 22 patients (56%) are still in CR, while 19 patients (44%) showed progression after a median time of 7 months after transplantation (range 2-29 months). Until today nine patients received an additional allogeneic transplantation. Eleven patients (27%) have died (3 DLBCL, 3 HL, 2 MCL, 1 GZL, 1 TCL and 1 FL), all due to lymphoma progression. Thus the 1- and 2-year PFS are 73.2% and 57.9% and the 1- and 2-year OVS 85.4% and 79.4%, respectively. In conclusion Benda-EAM is feasible with a quite promising outcome. Currently an international randomized phase II trial comparing Benda-EAM with BEAM is recruiting. So far thirty-five of 110 planned patients are randomized and first results are expected for 2018.
