Abstract
Diffuse large B-cell lymphoma (DLBCL) includes two prognostically important subtypes, the germinal center B-cell (GCB) and the non-GCB types. The aim of this study was to evaluate immunohistochemical approaches for predicting the survival of patients with DLBCL following autologous hematopoietic stem cell transplantation (AHSCT). We identified 62 patients with DLBCL who either had an initial complete remission (17 patients) or received salvage chemotherapy for relapsed or refractory disease (45 patients), followed by AHSCT. Tissue microarrays were immunostained with monoclonal antibodies against GCET1, CD10, BCL6, MUM1, FOXP1 and LMO2. Using the Hans algorithm, we classified 50% of the cases as GCB type, whereas the Choi algorithm classified 58% as GCB type and LMO2 was positive in 69%. However, no significant differences were found in the 5-year overall or event-free survivals using any of these approaches. In conclusion, cell of origin fails to predict survival of DLBCL patients treated with AHSCT.

Abstract
Autologous stem cell transplantation (ASCT) consolidation remains the treatment of choice for patients with relapsed diffuse large B cell lymphoma. The impact of rituximab combined with chemotherapy in either first- or second-line therapy on the ultimate results of ASCT remains to be determined, however. This study was designed to evaluate the benefit of ASCT in patients achieving a second complete remission after salvage chemotherapy by retrospectively comparing the disease-free survival (DFS) after ASCT for each patient with the duration of the first complete remission (CR1). Between 1990 and 2005, a total of 470 patients who had undergone ASCT and reported to the European Blood and Bone Transplantation Registry with Medical Essential Data Form B information were evaluated. Of these 470 patients, 351 (74%) had not received rituximab before ASCT, and 119 (25%) had received rituximab before ASCT. The median duration of CR1 was 11 months. The median time from diagnosis to ASCT was 24 months. The BEAM protocol was the most frequently used conditioning regimen (67%). After ASCT, the 5-year overall survival was 63% (95% confidence interval, 58%-67%) and 5-year DFS was 48% (95% confidence interval, 43%-53%) for the entire patient population. Statistical analysis showed a significant increase in DFS after ASCT compared with duration of CR1 (median, 51 months versus 11 months; P < .001). This difference was also highly significant for patients with previous exposure to rituximab (median, 10 months versus not reached; P < .001) and for patients who had experienced relapse before 1 year (median, 6 months versus 47 months; P < .001). Our data indicate that ASCT can significantly increase DFS compared with the duration of CR1 in relapsed diffuse large B cell lymphoma and can alter the disease course even in patients with high-risk disease previously treated with rituximab.

Abstract
Autologous stem cell transplantation (ASCT) is an established therapeutic modality in the treatment of lymphomas, especially in the relapse setting. It is also under investigation after first-line therapy, for example, in patients with mantle cell or T cell lymphomas. Each year more than 6000 autotransplants for lymphomas are reported to the European Blood and Marrow Transplantation (EBMT) registry. The number of allogeneic stem cell transplantations (alloSCT) in lymphoma patients has increased over the last decade, with about 1200 transplanted lymphoma patients annually reported to the registry. Optimal timing and indications for alloSCT are not well defined because of absence of randomized trials. Developments in the treatment of lymphomas including immunotherapy have changed the clinical scenarios in regard to ASCT, and many published studies are now outdated. On the other hand, patients relapsing after immunochemotherapy may derive less benefit from ASCT. Consequently, there is an increasing interest in using alloSCT not only in lymphoma patients relapsing after ASCT but also in earlier phases in specific circumstances. Although curative potential is higher with alloSCT compared with ASCT, its wider use has been hindered by excessive nonrelapse mortality (NRM). Along with decreasing NRM figures, popularity of alloSCT may increase in the near future, possibly with the expense of ASCT. Prospective, randomized studies are needed to evaluate feasibility and efficacy of alloSCT in several clinical settings, as most published evidence is based on retrospective registry data or single-center experiences.

Synergistic effects of combination with fludarabine and carboplatin depend on fludarabine-mediated inhibition of enhanced nucleotide excision repair in leukemia. Int J Hematol 2011; 94:378-389.

Abstract
Overcoming drug resistance remains a major obstacle to curing relapsed or refractory lymphoma and obtaining a beneficial long-term prognosis for patients, despite the introduction of several salvage regimens to date. Our ultimate purpose is to establish a standard second-line salvage chemotherapy regimen for curing relapsed/refractory lymphoma. In this basic pre-clinical study, we evaluated a combination regimen consisting of 9-β-D: -arabinofuranosyl-2-fluoroadenine (F-araA) and carboplatin that targeted nucleotide excision repair (NER) of DNA in five representative leukemia lineages in vitro. Isobologram analysis demonstrated that simultaneous exposure to these two drugs produced synergistic interactions in U937 and K562 cells, in which lines showed enhanced NER activity by the measurement of UV or drug-induced DNA strand break (comet assay), or quantitation of ERCC1 mRNA (RT-PCR), a key enzyme for NER. Histone γH2AX formation was synergistically induced, but no such formation was observed after exposure to either agent alone in K562 cells. In summary, we synergistically inhibited the NER activity of leukemia cells by treating them with a combination of F-araA and carboplatin, suggesting that this combinatory regimen could be used as a novel salvage therapy for refractory or drug-resistant lymphoma.

Abstract
Early relapse is a parameter that affects clinical outcomes in relapsed diffuse large B cell lymphoma (DLBCL). The prognostic value of lymphopenia following the completion of first-line therapy and the relationship between lymphopenia and early relapse are unknown. Therefore, we studied the role of absolute lymphocyte count (ALC) on early relapse. We retrospectively analyzed de novo DLBCL patients who were treated with rituximab-containing treatment between 2003 and 2010. The median age at the time of diagnosis of 59 DLBCL patients was 71 years. We identified no association between ALC at diagnosis and ALC following the completion of first-line therapy. Among all patients analyzed, 13 (22%) patients were confirmed to exhibit early relapse. Low ALC following the completion of first-line therapy was significantly associated with early relapse by univariate analysis [hazard ratio (HR) = 4.05; 95% confidence interval (CI), 1.11-14.73; P = 0.02] and multivariate analysis (HR = 4.66; 95% CI, 1.24-17.48; P = 0.023). The low ALC group tended to have worse outcomes than the high ALC group with lower rates of progression-free survival (66% and 74%, respectively; P = 0.13) and overall survival (74% and 86%, respectively; P = 0.09), but these differences did not reach statistically. Lymphopenia following the completion of first-line therapy can be used as a marker to predict early relapse.

Abstract
We designed a phase 1-2 study to evaluate the safety and the efficacy of increasing doses of bendamustine (160 mg/m², 180 mg/m², and 200 mg/m² given on days -7 and -6) coupled with fixed doses of etoposide, cytarabine, and melphalan (BeEAM regimen) as the conditioning regimen to autologous stem cell transplantation for resistant/relapsed lymphoma patients. Forty-three patients (median age, 47 years) with non-Hodgkin (n = 28) or Hodgkin (n = 15) lymphoma were consecutively treated. Nine patients entered the phase 1 study; no patients experienced a dose-limiting toxicity. Thirty-four additional patients were then treated in the phase 2. A median number of 6 × 10⁶ CD34(+) cells/kg (range, 2.4-15.5) were reinfused. All patients engrafted, with a median time to absolute neutrophil count > 0.5 × 10⁹/L of 10 days. The 100-day transplantation-related mortality was 0%. After a median follow-up of 18 months, 35 of 43 patients (81%) are in complete remission, whereas 6 of 43 relapsed and 2 of 43 did not respond. Disease type (non-Hodgkin lymphomas vs Hodgkin disease) and disease status at transplantation (chemosensitive vs chemoresistant) significantly influenced DFS (P = .01; P = .007). Remarkably, 4 of 43 (9%) patients achieved the first complete remission after receiving the high-dose therapy with autologous stem cell transplantation. In conclusion, the new BeEAM regimen is safe and effective for heavily pretreated lymphoma patients. The study was registered at European Medicines Agency (EudraCT number 2008-002736-15).

Abstract
Rituximab (the chimeric anti-CD20 antibody) is widely used in the treatment of CD20 positive non-Hodgkin's lymphoma (NHL). The response rate at relapse after repeated use in prior CD20 positive responders is lower than 50%. Several mechanisms can be responsible for rituximab resistance. CD20 negative relapses which transformed from CD20 positive aggressive and indolent forms of lymphoma can be the one of the reason of secondary resistance to rituximab. The authors report a case with combination of aggressive and indolent form of lymphoma who relapsed after 7 months from the last dose of rituximab therapy. CD20 transformed negative from positive in her relapsed disease. Patients with CD20 positive B cell NHL must rebiopsy after first line rituximab therapy if their disease relapsed or progressed.

Abstract
We conducted a matched-cohort analysis of autologous transplant conditioning regimens for diffuse large cell lymphoma in 92 patients treated with either radioimmunotherapy (RIT) or total body irradiation (TBI)-based conditioning regimens. The RIT regimen consisted of 0.4 mCi/kg of (90)Y-ibritumomab tiuxetan plus BEAM (BCNU, etoposide, cytarabine, melphalan). The TBI-based regimen combined fractionated TBI at 1200 cGy, with etoposide and cyclophosphamide. Five factors were matched between 46 patient pairs: age at transplant ±5 years, disease status at salvage, number of prior regimens, year of diagnosis ±5 years, and year of transplantation ±5 years. Patients in the TBI group had higher rates of cardiac toxicity and mucositis, whereas Z-BEAM patients had a higher incidence of pulmonary toxicity. Overall survival at 4 years was 81.0% for the Z-BEAM and 52.7% for the TBI group (P = .01). The 4-year cumulative incidence of relapse/progression was 40.4% and 42.1% for Z-BEAM and TBI, respectively (P = .63). Nonrelapse mortality was superior in the Z-BEAM group: 0% compared with 15.8% for TBI at 4 years (P < .01). Our data demonstrate that RIT-based conditioning had a similar relapse incidence to TBI, with lower toxicity, resulting in improved overall survival, particularly in patients with ≥2 prior regimens.

Abstract
Information regarding rituximab monotherapy with eight weekly infusions for relapsed or refractory indolent B cell non-Hodgkin lymphoma (B-NHL), in particular for patients pretreated with rituximab, is limited. To evaluate the efficacy and safety of eight doses of rituximab monotherapy, 52 patients with relapsed or refractory indolent B-NHL were enrolled in the present study. Forty of 45 eligible patients (89%) had follicular lymphoma and 24 (53%) were at intermediate or high risk group according to the Follicular Lymphoma International Prognostic Index. The median number of prior chemotherapy regimens was 1 (range 1-7). At the median follow-up of 12.2 months, the overall response rate (ORR), complete response rate (%CR), and median progression-free survival (PFS) were 69% (95% confidence interval [CI] 53%-82%), 47% (95% CI 32%-62%), and 15.6 months (95% CI 10.6- months), respectively. In the 33 patients pretreated with rituximab, the ORR, %CR, and median PFS were inferior compared with values for the 12 patients who had not received rituximab previously (64%vs 83% for ORR; 39%vs 67% for %CR; and 13.8 vs 17.5 months for median PFS, respectively). All mild-to-moderate infusion-related toxicities were reversible. Grade 3/4 non-hematologic adverse events occurred in six of the 52 patients. Two patients developed Grade 4 late-onset neutropenia and a decrease (>50%) in serum immunoglobulin was observed in six patients. In conclusion, rituximab monotherapy with eight weekly infusions is effective in relapsed patients with indolent B-NHL, with acceptable toxicities, including in patients pretreated with rituximab; however, careful monitoring is recommended for infections associated with late-onset neutropenia and hypogammaglobulinemia.

Abstract
AbstractThe prognostic value of interim positron emission tomography (PET) interpreted according to visual criteria is a matter of debate in diffuse large B-cell lymphoma (DLBCL). Maximal standardized uptake value reduction (ΔSUVmax) may better predict outcome. To compare the prognostic value of both methods, we analyzed PET done at baseline (PET0) and after 2 (PET2) and 4 (PET4) cycles in 85 patients with high-risk DLBCL enrolled on a prospective multicenter trial. All images were centrally reviewed and interpreted visually according to the International Harmonization Project criteria and by computing ΔSUVmax between PET0 and PET2 (ΔSUVmaxPET0-2) or PET4 (ΔSUVmaxPET0-4). Optimal cutoff to predict progression or death was 66% for ΔSUVmaxPET0-2 and 70% for ΔSUVmaxPET0-4. Outcomes did not differ significantly whether PET2 and PET4 were visually positive or negative. Inversely, ΔSUVmaxPET0-2 analysis (> 66% vs ≤ 66%) identified patients with significantly different 2-year progression-free survival (77% vs 57%; P = .0282) and overall survival (93% vs 60%; P < .0001). ΔSUVmaxPET0-4 analysis (> 70% vs ≤ 70%) seemed even more predictive for 2-year progression-free survival (83 vs 40%; P < .0001) and overall survival (94% vs 50%; P < .0001). ΔSUVmax analysis of sequential interim PET is feasible for high-risk DLBCL and better predicts outcome than visual analysis. The trial was registered at http://clinicaltrials.gov as NCT00498043.

Abstract
BACKGROUND As rituximab combined with CHOP improves complete remission and overall survival in diffuse large B-cell lymphoma, intensified chemotherapy followed by autologous stem-cell transplantation has also been advocated for high-risk patients. The aim of this study was to establish whether or not combining rituximab with high-dose chemotherapy and auto-transplantation also benefits patient survival. DESIGN AND METHODS The LNH2003-3 study was a phase II trial including diffuse large B-cell lymphoma patients with 2 or 3 International Prognostic Index factors. They received four cycles of intensive biweekly chemotherapy with rituximab, doxorubicine, cyclophosphamide, vindesine, bleomycine, prednisolone (R-ACVBP) followed by auto-transplantation in responding patients. Two hundred and nine patients under 60 years of age were included in the study and 155 responding patients underwent auto-transplantation. In addition, a case-control study was performed by matching (1:1) 181 patients treated with R-ACVBP with ACVBP patients not given rituximab but submitted to auto-transplantation from the previous LNH1998-3 trial. RESULTS With a median follow up of 45 months, 4-year progression-free survival and overall survival were estimated at 76% (CI: 69-81) and 78% (CI: 72-83), respectively. There was no difference between patients with 2 or 3 International Prognostic Index factors. Four year progression-free survival was significantly higher in R-ACVBP than ACVBP patients (74% vs. 58%; P=0.0005). There was also a significant increase in 4-year overall survival (76% vs. 68%; P=0.0494). CONCLUSIONS In high-risk diffuse large B-cell lymphoma patients, treatment with R-ACVBP followed by auto-transplantation results in a 78% 4-year overall survival which should be compared to other approaches.

Abstract
Historically, high levels of treatment-related mortality restricted the use of standard myeloablative allogeneic stem-cell transplantation to a minority of young and fit patients with lymphoma. Over the last decade, increasing numbers of patients with lymphoma have undergone allogeneic stem-cell transplantation using reduced-intensity protocols that are associated with lower toxicity and reduced transplantation-related mortality. Graft-versus-lymphoma effects contribute to the therapeutic effect in patients with indolent or Hodgkin's lymphoma. However, definitive evidence for efficacy of this strategy is lacking because most patients undergoing transplantation do so after failure of several lines of treatment, leaving no obvious comparator arm for randomized controlled studies. Nevertheless, encouraging results have been reported for selected patients for most lymphoma subtypes, with pretransplantation disease status emerging as the most important predictor of outcome. The major long-term toxicity is chronic graft-versus-host disease that contributes to ill health in a significant minority of survivors. In the future, risk-adapted trials that evaluate reduced-intensity allogeneic transplantation in patients with predicted poor outcomes with immunochemotherapy or autologous transplantation will be important in determining the role of this treatment.

Abstract
Purpose In diffuse large B-cell lymphoma (DLBCL), prior studies suggest that concordant bone marrow involvement with DLBCL portends a poorer prognosis, whereas discordant bone marrow involvement with small B-cell lymphoma does not. We examined the significance of bone marrow involvement in patients treated in the current era of therapy including rituximab. Patients and Methods We performed a retrospective analysis of the prognostic impact of bone marrow involvement in an unselected population of patients with newly diagnosed DLBCL treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone in British Columbia and Auckland, New Zealand, with complete clinical information and evaluable staging bone marrow biopsies. Results In total, 795 patients were identified. Six hundred seventy (84.3%) of 795 had a negative bone marrow, 67 patients (8.4%) had concordant and 58 (7.3%) had discordant involvement. Median follow-up was 41 months (range, 1 to 115). Progression-free survival (PFS) was inferior in those with concordant (P < .001) and discordant (P = .019) involvement while overall survival (OS) was inferior in those with concordant involvement (P < .001) only. In a multivariate analysis controlling for the International Prognostic Index (IPI) score, concordant involvement remained an independent predictor of PFS (P < .001) and OS (P = .007). Discordant involvement was associated with older age, elevated lactate dehydrogenase, advanced stage, and increased number of extranodal sites and was not a negative prognostic factor independent of the IPI score. Conclusion The negative prognostic impact of discordant involvement is adequately represented by the IPI score, while the risk with concordant involvement is greater than that encompassed by this predictor. The results emphasize the need for accurate staging assessment of bone marrow involvement in DLBCL.

Abstract
PURPOSE OF REVIEW Addition of rituximab to conventional chemotherapies was shown to improve outcome in phase 3 trials of patients with diffuse large B-cell lymphoma (DLBCL). As the challenge in the rituximab era is to increase treatment efficacy, the present review attempts to assess the results of high-dose therapy and autologous stem cell transplantation (ASCT) as front-line treatment for poor-prognosis DLBCL patients. RECENT FINDINGS French and Italian groups demonstrated in several phase 2 series that high-dose front-line treatment with rituximab plus ASCT gave better results than without rituximab. In relapse, the CORAL study, a worldwide collaborative effort, showed that assessment of the latest results for ASCT should also take account of other prognostic factors, including advanced stage, chemo/rituximab refractory disease and a short interval between remission and relapse. This underscores the need for innovative therapeutic strategies such as radiolabelled conditioning regimens and maintenance after ASCT. Allogeneic transplantation, which generates a graft-versus-lymphoma effect that reduces the likelihood of relapse, may also be beneficial for high-risk patients. SUMMARY In this setting, new approaches based on improved understanding of the biology of the disease will play a key role.

Abstract
INTRODUCTION Although diffuse large B-cell lymphoma (DLBCL) is commonly considered as a cancer with a high cure rate with conventional therapies recent studies demonstrate that different biological variants of DBLCL exist, and that patients with one DLBCL variant and DLBCL patients who relapse early following rituximab-based therapy have markedly poorer outcomes with conventional management strategies. Over the last decade, there has been an increasing exploration of novel therapies derived from improved understanding of DLBCL biology and tumor-host interactions. AREAS COVERED This review examines the biological basis for novel therapeutic approaches in DLBCL and the early clinical data on compounds derived from this research. A description of the expanding options of novel agents and combination therapies for patients with poor risk DLBCL is provided. EXPERT OPINION Several promising novel agents and novel therapeutic combinations are under development for patients with poor risk DLBCL. Carefully designed clinical trials that build on our improved understanding of DLBCL biology and utilize tissue samples to examine the activity of novel combination therapies should expand treatment options for DLBCL patients in the future.

Abstract
A 38-year-old man presented to our hospital with abdominal pain and melena. Gastrointestinal endoscopy revealed a large gastric ulcer, and the pathological diagnosis of diffuse large B-cell lymphoma (DLBCL) was made based on immunohistochemical findings. Left diplopia developed soon after commencement of chemotherapy. Despite normal findings from head MRI, orbital involvement in DLBCL was detected with 18F-fluorodeoxyglucose positron emission tomography (FDG-PET). The patient was treated with salvage chemotherapy with success. Treatment analysis using FDG-PET for patients with DLBCL, especially for those with clinical symptoms and negative findings on conventional modalities, may be useful for assessing disease status and adjusting treatments.

Abstract
Despite overall improvements in outcomes of diffuse large B-cell lymphoma (DLBCL), approximately one-third of patients will develop relapsed/refractory disease that remains a major cause of morbidity and mortality. Novel insights from gene-expression analyses have increased our understanding of chemotherapy resistance and yielded rational targets for therapeutic intervention to both prevent and treat relapsed/refractory DLBCL. The clinical approach to relapsed/refractory DLBCL should include high-dose therapy and autologous stem cell transplantation (HD-ASCT) with curative intent in patients without comorbidities. Results from the recently reported CORAL study suggest that patients refractory to rituximab-containing regimens have inferior outcomes with HD-ASCT. Ongoing efforts to improve ASCT include novel conditioning regimens and evaluation of maintenance approaches after ASCT. Unfortunately, because the majority of patients are not eligible for ASCT due to refractory disease or age/comorbidities, these approaches have limited impact. The large group of patients not eligible for ASCT have incurable disease and should be referred for clinical trials of rationally targeted agents.

Abstract
Clofarabine has significant single-agent activity in patients with indolent and aggressive non-Hodgkin lymphoma and synergizes with DNA-damaging drugs. Treatment, however, may be associated with severe and prolonged myelosuppression. We conducted a phase I trial to determine the maximum tolerated dose (MTD) of clofarabine in combination with high-dose etoposide and cyclophosphamide followed by autologous peripheral blood stem cell transplantation in patients with refractory non-Hodgkin lymphoma (NHL). Patients received clofarabine at 30-70 mg/m(2)/day on days -6 to -2 in successive cohorts, in combination with etoposide 60 mg/kg (day -8), and cyclophosphamide 100 mg/kg (day -6), followed by filgrastim-mobilized PBSC on day 0. Sixteen patients of median age 57 (range: 32-67) years with diffuse large B cell (n = 8), follicular (n = 5), or mantle cell (n = 3) lymphoma that was either primary refractory (n = 2) or relapsed and refractory (n = 14) were treated at 5 clofarabine dose levels: 30 (n = 3), 40 (n = 3), 50 (n = 3), 60 (n = 3), and 70 mg/m(2)/day (n = 4) in combination with etoposide and cyclophosphamide. All patients had grade 4 neutropenia and thrombocytopenia. Grade 3-4 nonhematologic toxicity was evenly distributed across all 5 dose levels, and included diarrhea (n = 3), mucositis (n = 1), nausea (n = 1), reversible elevation of alanine aminotranferease/aspartate aminotransferase (AST/ALT) (n = 1) or bilirubin (n = 1), and hemorrhagic cystitis (n = 1); all resolved by day +30 following transplantation. The MTD was not reached. No treatment-related deaths occurred. At day +30, 13 patients achieved a complete remission (CR) or unconfirmed CR (CR(U)), and 2 patients achieved a partial response, for an overall response rate of 94%. After a median follow-up of 691 days, the 1-year progression-free survival (PFS) and overall survival (OS) were 63% (95% confidence interval [CI]: 43%-91%) and 68% (95% CI: 49%-96%), respectively. We recommend clofarabine 70 mg/m(2)/day × 5 days as a phase II dose in combination with high-dose etoposide and cyclophosphamide for further testing as a preparative regimen in NHL patients undergoing autologous PBSC transplantation.

Abstract
We report the outcome of patients included in the LNH-98.5 study, which compared cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) to rituximab plus CHOP (R-CHOP) therapy in 399 patients with diffuse large B-cell lymphoma (DLBCL) aged 60 to 80 years, with a median follow-up time of 10 years. Clinical event information was updated in all living patients (with the exception of 3 patients) in 2009. Survival end points were improved in patients treated with R-CHOP: the 10-year progression-free survival was 36.5%, compared with 20% with CHOP alone, and the 10-year overall survival was 43.5% compared with 27.6%. The same risk of death due to other diseases, secondary cancers, and late relapses was observed in both study arms. Relapses occurring after 5 years represented 7% of all disease progressions. The results from the 10-year analysis confirm the benefits and tolerability of the addition of rituximab to CHOP. Our findings underscore the need to treat elderly patients as young patients, with the use of curative chemotherapy.
