Abstract
PURPOSE Follicular lymphoma (FL) is an indolent disorder that is treatable but considered incurable with chemotherapy alone. The curative potential of allogeneic transplantation using conventional myeloablative conditioning has been demonstrated, but this approach is precluded in the majority of patients with FL because of excessive toxicity. Thus, reduced-intensity conditioning regimens are being explored. PATIENTS AND METHODS This study reports the outcome of 82 consecutive patients with FL who underwent transplantation using fludarabine, melphalan, and alemtuzumab for in vivo T-cell depletion. Patients were heavily pretreated, having received a median of four lines of prior therapy, and 26% had experienced treatment failure with previous autologous transplantation. Median patient age was 45 years, and 52% of patients received stem cells from unrelated donors. RESULTS With a median follow-up time of 43 months, the nonrelapse mortality was 15% at 4 years (8% for sibling and 22% for unrelated donor transplantations), acute grade 2 or 3 graft-versus-host disease (GVHD) occurred in 13%, and the incidence of extensive chronic GVHD was only 18%. Although relapse risk was 26%, this was significantly reduced where mixed chimerism had been converted to full donor chimerism by the use of donor lymphocyte infusion (DLI; P = .03). In addition, 10 (77%) of 13 patients given DLI for relapse after transplantation experienced remission, with nine of these responses being sustained. Current progression-free survival at 4 years was 76% for the whole cohort (90% for those with sibling donors and 64% for those with unrelated donors). CONCLUSION The excellent long-term survival with associated low rates of GVHD and the frequency and durability of DLI responses make this an extremely encouraging strategy for the treatment and potential cure of FL.

Abstract
Adoptive transfer of in vivo generated antigen-specific donor-derived T-cells is increasingly recognized as an effective approach for the treatment or prevention of EBV lymphomas and cytomegalovirus infections complicating allogeneic hematopoietic cell transplants. This review examines evidence from preclinical experiments and initial clinical trials to critically assess both the potential and current limitations of adoptive transfer of donor T-cells sensitized to selected minor alloantigens of the host or to peptide epitopes of proteins, differentially expressed by clonogenic leukemia cells, such as the Wilms tumor protein, WT-1, as a strategy to treat or prevent recurrence of leukemia in the post-transplant period.

Abstract
Although much has been published on the application of autologous and allogeneic hematopoietic stem cell transplantation in patients with follicular lymphoma (FL), no uniform consensus exists among physicians on when to use this strategy. Three large randomized trials failed to show a survival benefit using autologous transplantation for FL patients in first complete remission. Similarly, many Phase II or registry-based studies have also failed to show a survival benefit with autologous transplantation in relapsed or refractory FL patients, although the progression-free survival seems to be prolonged in transplant recipients. Allogeneic stem cell transplantation can cure a subset of patients with FL, but high nonrelapse mortality and morbidity remain a concern. No consensus exists on what conditioning regimen should be used, or how the newer monoclonal antibodies should be incorporated into the transplant paradigm. Here we present a review of the role of autologous and allogeneic hematopoietic stem cell transplantation in patients with FL.

Abstract
Recipient antigen presenting cells (APCs) are required for CD8-mediated graft-versus-host disease (GVHD), and have an important and nonredundant role in CD4-mediated GVHD in mouse major histocompatibility complex-matched allogeneic bone marrow transplantation (alloBMT). However, the precise roles of specific recipient APCs-dendritic cells, macrophages, and B cells-are not well defined. If recipient B cells are important APCs they could be depleted with rituximab, an anti-CD20 monoclonal antibody. On the other hand, B cells can downregulate T cell responses, and consequently, B cell depletion could exacerbate GVHD. Patients with B cell lymphomas undergo allogeneic hematopoietic stem cell transplantation (alloSCT) and many are B-cell-deficient because of prior rituximab. We therefore studied the role of recipient B cells in major histocompatibility complex-matched murine models of CD8- and CD4-mediated GVHD by using recipients genetically deficient in B cells and with antibody-mediated depletion of host B cells. In both CD4- and CD8-dependent models, B cell-deficient recipients developed clinical and pathologic GVHD. However, although CD8-mediated GVHD was clinically less severe in hosts genetically deficient in B cells, it was unaffected in anti-CD20-treated recipients. These data indicate that recipient B cells are not important initiators of GVHD, and that efforts to prevent GVHD by APC depletion should focus on other APC subsets.

Abstract
BACKGROUND Chemotherapy sensitivity, defined simply as at least a partial response to chemotherapy, is an important outcome predictor for non-Hodgkin lymphoma (NHL) patients undergoing reduced-intensity allogeneic hematopoietic stem cell transplantation (allo-HCT). The authors hypothesized that further differentiation of chemotherapy sensitivity by specific response, complete remission (CR) versus partial remission (PR) versus stable disease (SD) versus progression of disease (PD), correlates with post-transplant outcomes. METHODS The impact of pretransplant and early (28 days) post-transplant disease response on transplant outcomes was analyzed in 63 NHL patients treated with reduced-intensity allo-HCT. RESULTS The 3-year event-free survival (EFS) and overall survival (OS) (median potential follow-up after reduced-intensity allo-HCT = 58 months) for all patients was 37% and 47%, respectively. The 3-year EFS based on pretransplant response was: CR = 50%; PR = 66%; SD = 18%; no patient with PD pretransplant reached 3-year follow-up. The 3-year OS based on pretransplant response was: CR = 63%; PR = 69%; SD = 45%. The 3-year EFS based on post-transplant response was: CR = 57%; PR = 32%; SD = 33%; no patient with PD post-transplant reached 3-year follow-up. The 3-year OS based on post-transplant response was: CR = 65%; PR = 43%; SD = 50%. In multivariate analyses, pretransplant response was the best predictor of EFS (P < .0001). Pretransplant response (P < .0001) and age (P = .0035) were jointly associated with OS. CONCLUSIONS These data suggest that NHL patients with pretransplant SD, generally considered inappropriate candidates, may benefit from reduced-intensity allo-HCT, and patients with pretransplant PD should only receive this therapy in clinical trials.

Abstract
Allogeneic stem cell transplantation (SCT) is an established therapy for patients with relapsed lymphoma, but the role of positron emission tomography (PET) scanning preallogeneic and postallogeneic SCT is uncertain. We investigated whether pretransplantation PET status predicted outcome after allogeneic SCT and whether PET surveillance after transplantation provided additional information compared with computed tomography (CT) scanning. Eighty consecutive patients with lymphoma who received a reduced-intensity allogeneic SCT were entered onto a prospective trial. PET and CT scans were performed before transplantation and up to 36 months after transplantation. Forty-two patients were PET-positive before transplantation. Pretransplantation PET status had no significant impact on either relapse rate or overall survival. Thirty-four relapses were observed, of which 17 were PET-positive with a normal CT scan at relapse. Donor lymphocyte infusion (DLI) was administered in 26 episodes of relapse and was guided by PET alone in 14 patients. These findings suggest that, in contrast to autologous SCT, pretransplantation PET status is not predictive of relapse and survival after allogeneic SCT for lymphoma. Posttransplantation surveillance by PET detected relapse before CT in half of episodes, often allowing earlier administration of DLI in patients with recurrent lymphoma, and permitted withholding of potentially harmful DLI in those with PET-negative masses on CT scans.

Abstract
BACKGROUND Allogeneic hematopoietic stem cell transplantation is an effective treatment for patients with poor risk lymphoma, at least in part because of the graft-versus-lymphoma effect. Over the past decade, reduced intensity conditioning regimens have been shown to offer results similar to those of conventional high-dose conditioning regimens but with lower toxicity early after transplantation, especially in patients with chemosensitive disease at transplant. DESIGN AND METHODS The aim of this study was to analyze the long-term outcome of patients with follicular lymphoma who received an HLA identical sibling allogeneic stem cell transplant with a reduced intensity conditioning regimen within prospective trials. The prospective multicenter studies considered included 37 patients with follicular lymphoma who underwent allogeneic stem cell transplantation between 1998 and 2007 with a fludarabine plus melphalan-based reduced intensity conditioning regimen. RESULTS The median age of the patients was 50 years (range, 34-62 years) and the median follow-up was 52 months (range, 0.6 to 113 months). Most patients (77%) had stage III-IV at diagnosis, and patients had received a median of three lines of therapy before the reduced intensity conditioning allogeneic stem cell transplantation. At the time of transplantation, 14 patients were in complete remission, 16 in partial remission and 7 had refractory or progressive disease after salvage chemotherapy. The 4-year overall survival rates for patients in complete remission, partial remission, or with refractory or progressive disease were 71%, 48% and 29%, respectively (P=0.09), whereas the 4-year cumulative incidences of non-relapse mortality were 26% (95% CI, 11-61), 33% (95% CI, 16-68) and 71% (95% CI, 44-100), respectively. The incidence of relapse for the whole group was only 8% (95% CI, 2-23). CONCLUSIONS We conclude that this strategy of reduced intensity conditioning allogeneic stem cell transplantation may be associated with significant non-relapse mortality in heavily pre-treated patients with follicular lymphoma, but a remarkably low relapse rate. Long-term survival is likely in patients without progressive or refractory disease at the time of transplantation.

Abstract
There is growing evidence incriminating B lymphocytes in the pathogenesis of graft-versus-host disease (GVHD). Better understanding of the role of B lymphocytes has uncovered new therapeutic approaches, such as CD20 blockade, which appear to be improving outcomes in allogeneic hematopoietic cell transplant recipients. Administration of the chimeric murine/human anti-CD20 monoclonal antibody, rituximab, prior to hematopoietic cell allografting or as part of preparative regimens appears to reduce treatment-related mortality and to improve posttransplant outcomes mainly by decreasing the incidence and severity of acute GVHD. This beneficial effect of rituximab has not had an impact, to the same extent on the incidence of chronic GVHD, which remains a significant cause of morbidity and mortality following hematopoietic cell allografting. Alternatively, rituximab has been shown to be effective for treatment of cGVHD, but data is limited because of the lack of randomized controlled clinical trials and the small sample size in most of the published series. Incorporation of rituximab into the therapeutic armamentarium of Epstein-Barr virus-associated posttransplant lymphoproliferative disorder has clearly improved the overall prognosis of this dreadful disease. This review highlights the evolving role of CD20 blockade in allogeneic hematopoietic cell transplantation and the need to continue to refine B cell depletion strategies in this setting.

Abstract
Stem cell transplantation in chronic lymphocytic leukemia (CLL) is an evolving field. Younger patients with high-risk disease might derive the greatest benefit from this approach and the availability of reduced-intensity conditioning regimens has made allogeneic stem cell transplantation more relevant to patients with CLL. Patient selection, timing of transplantation, and method of conditioning, stem cell delivery and immunosuppression appear to influence outcomes. We collect and review the available data to assist clinical decision-making in this field.

Abstract
T-cell depleted allogeneic hematopoietic SCT (TCD-HSCT) have shown durable disease-free survival with a low risk of GVHD in patients with AML. We investigated this approach in 61 patients with primary refractory or relapsed non-Hodgkin lymphoma (NHL), who underwent TCD-HSCT from January 1992 through September 2004. Patients received myeloablative cytoreduction consisting of hyperfractionated total body irradiation, followed by either thiotepa and cyclophosphamide (45 patients) or thiotepa and fludarabine (16 patients). We determined the second-line age-adjusted International Prognostic Index score (sAAIPI) before transplant transplant. Median follow-up of surviving patients is 6 years. The 10-year OS and EFS were 50% and 43%, respectively. The relapse rate at 10 years was 21% in patients with chemosensitive disease and 52% in those with resistant disease at time of HSCT. Nine of the 18 patients who relapsed entered a subsequent CR. OS (P=0.01) correlated with the sAAIPI. The incidence of grades II-IV acute GVHD was 18%. We conclude that allogeneic TCD-HSCT can induce high rates of OS and EFS in advanced NHL with a low incidence of GVHD. Furthermore, the sAAIPI can predict outcomes and may be used to select the most appropriate patients for this type of transplant.

Abstract
In adults, the bone marrow compartment contains hematopoietic stem cells (HSCs) which can differentiate into progenitors with more restricted lineage potential and generate all cellular elements of the blood. HSCs for stem cell transplantation can be obtained by bone marrow collection, mobilization into peripheral blood followed by apheresis, or use of stem cells from cord blood. Currently, hematopoietic stem cell transplantation (SCT) is used to treat patients with various hematological diseases. Although substantial progress has been made, a number of challenges can limit the efficacy of HSC transplantation, including the occurrence of graft-versus-host disease (GvHD) in allogeneic stem cell transplantation (ASCT), the susceptibility of patients to opportunistic infections and relapse of malignancies after SCT. Recent studies indicate that small interfering RNAs (siRNAs) can specifically and efficiently interfere with the expression of oncogenic genes. Therefore, the possibility of interfering with the expression of these proteins in hematopoietic cells may offer a new option to correct cell differentiation and function. In addition to the generation of T cells restricted by nonself MHC as reviewed by Stauss and colleagues in 1999, the modulation of NK cell receptor expression and T-cell activation is a new strategy that could limit GvHD. This chapter reviews the recent advances in ASCT and discusses the potential application of RNAi in hematopoietic cells.

Abstract
Nonmyeloablative stem cell transplantation (NST) is increasingly used with beneficial effects because it can be applied to older patients with hematological malignancies and those with various complications who are not suitable for conventional myeloablative stem cell transplantation (CST). Various conditioning regimens differ in their myeloablative and immunosuppressive intensity. Regardless of the type of conditioning regimen, graft-versus- host disease (GVHD) in NST occurs almost equally in CST, although a slightly delayed development of acute GVHD is observed in NST. Although graft-versus-hematological malignancy effects (i.e., graft-versus-leukemia effect, graft-versus-lymphoma effect, and graft-versus-myeloma effect) also occur in NST, completely eradicating residual malignant cells through allogeneic immune responses is insufficient in cases with rapidly growing disease or uncontrolled progressive disease. Donor lymphocyte infusion (DLI) is sometimes combined to support engraftment and to augment the graft-versus-hematological malignancy effect, such as the graft-versus-leukemia effect. DLI is especially effective for controlling relapse in the chronic phase of chronic myelogenous leukemia, but not so effective against other diseases. Indeed, NST is a beneficial procedure for expanding the opportunity of allogeneic hematopoietic stem cell transplantation to many patients with hematological malignancies. However, a more sophisticated improvement in separating graft-versus-hematological malignancy effects from GVHD is required in the future.

Abstract
Bone marrow engraftment studies are used to evaluate the level of donor versus recipient cells in post-transplant peripheral blood or bone marrow specimens. Unique DNA fingerprints identified from the recipient and the donor are used to determine the proportion of each contained within the total DNA extracted from the post-transplant specimen. These percentages correspond to relative amounts of donor and recipient cells in the specimen. Engraftment studies are sequentially performed on transplant patients to monitor closely the levels of donor and recipient cells so that appropriate therapeutic intervention can proceed if and when needed. This unit describes the use of fluorescent PCR for amplification of genomic short tandem repeats (STR). STR analysis is now considered the gold standard for engraftment studies and provides a quick and accurate assessment of the contribution of both donor and/or recipient hematopoietic cells in post-transplantation specimens.

Abstract
Patients with primary large B-cell lymphomas of the mediastinum (PMBL) who suffer early relapse have a low likelihood of achieving a prolonged second remission with conventional salvage therapy. Here we describe the case of a 33-year-old woman with PMBL refractory to 6 lines of therapy before undergoing salvage therapy with rituximab, ifosfamide and etoposide followed by high-dose therapy, autologous transplantation, and sequential non-myeloablative allogeneic transplantation, who remains in ongoing complete remission for more than 39 months and is apparently cured. The specific roles of the components of the successful salvage therapy are discussed.

Abstract
Progressive disease is the major cause of treatment failure after autologous hematopoietic stem cell transplantation for relapsed or refractory non-Hodgkin's lymphoma. An augmented high-dose regimen of cyclophosphamide 7,200 mg/m2, carmustine 300 - 400 mg/m2, and etoposide 2,400 mg/m2 (CBV) was developed in an attempt to improve disease control post-transplant. Sixty-seven adult patients received augmented CBV followed by infusion of unpurged autologous peripheral blood stem cells. Thirty seven patients had relapsed after standard chemotherapy, 28 patients had primary refractory disease, and 2 patients had transformed lymphoma in first partial response. Treatment-related mortality was 4%. Actuarial four year overall survival and progression-free survival were 46+/-8% and 36+/-6%, respectively. Risk factors for disease progression were histologic involvement of marrow by lymphoma and infusion of increased numbers of CD34 + cells per kg in the stem cell autograft. The outcome for patients with relatively chemorefractory disease (defined as 25 - 49% reduction in tumor volume after salvage chemotherapy) was no different than that for patients with chemosensitive disease. Compared to standard high-dose CBV regimens, augmented CBV does not appear to have substantially improved disease control. Prospective study of the association between inferior progression-free survival and infusion of higher CD34 + cell doses in stem cell autografts is warranted.

Abstract
Nonmyeloablative hematopoietic cell transplantation (HCT) has been used to treat patients with advanced or high-risk lymphoid malignancies. We studied 65 patients (median age 46 years) receiving an umbilical cord blood (UCB) graft after a single conditioning regimen consisting of cyclophosphamide (50 mg/kg) on day -6, fludarabine (40 mg/m(2)) daily on days -6 to -2, as well as a single fraction of total-body irradiation (TBI) (200 cGy) along with cyclosporine mycophenolate mofetil immunosuppression. Median time to neutrophil and platelet recovery was 7.5 days (range: 0-32) and 46 days (range: 8-111), respectively. Cumulative incidences of grade II-IV, grade III-IV acute, and chronic graft-versus-host disease (aGVHD, cGVHD) were 57% (95% confidence interval [CI]: 43%-70%), 25% (95% CI: 14%-35%), and 19% (95% CI: 9%-29%), respectively. Transplant-related mortality at 3 years was 15% (95% CI: 5%-26%). Median follow-up was 23 months. The progression free-survival (PFS), current PFS and overall survival (OS) were 34% (95% CI: 21%-47%), 49% (95% CI: 36%-62%), and 55% (95% CI: 42%-70%) at 3 years. Based on our data, we conclude that a nonmyeloablative conditioning regimen followed by UCB transplantation is an effective treatment for patients with advanced lymphoid malignancies who lack a suitable sibling donor.

Abstract
PURPOSE OF REVIEW Hematopoietic stem-cell transplantation is an effective treatment option for follicular lymphoma. This review summarizes recent updates of the literature focusing on the available long-term follow-up of high-dose therapeutic approaches. RECENT FINDINGS Autologous transplantation can prolong overall survival in relapsed disease and can extend progression-free survival in first remission. With more than 10 years of follow-up, the survival curves demonstrate a plateau indicating a potential cure in certain patients. Use of allogeneic transplantation may result in cure as well, but has been plagued by high treatment-related mortality rates when myeloablative conditioning is used. The decreased toxicity of reduced-intensity conditioning is more applicable to the older follicular lymphoma population, but long-term follow-up data are lacking. SUMMARY For selected patients, both autologous and allogeneic transplantation offer the possibility of prolonged survival and can result in a cure in up to 25-45% of cases. It is unclear whether to incorporate monoclonal antibody or radioimmunoconjugate therapy. Stem-cell transplantation should at least be considered in patients younger than 60 years, possibly early in the disease course. Late consequences such as an increased risk of second malignancy may compromise this approach and close patient follow-up is essential.

Abstract
Non-Hodgkin's lymphoma (NHL) includes a diverse set of conditions ranging from high-grade aggressive to more indolent low-grade disease. Hematopoietic stem cell transplantation (HSCT) has a valuable role in the management of these conditions and can provide long-term remission in selected cases. This article presents the current use of allogeneic and autologous HSCT in a number of subtypes of NHL.

Abstract
PURPOSE To determine risk factors of umbilical cord blood transplantation (UCBT) for patients with lymphoid malignancies. PATIENTS AND METHODS We evaluated 104 adult patients (median age, 41 years) who underwent unrelated donor UCBT for lymphoid malignancies. UCB grafts were two-antigen human leukocyte antigen-mismatched in 68%, and were composed of one (n = 78) or two (n = 26) units. Diagnoses were non-Hodgkin's lymphoma (NHL, n = 61), Hodgkin's lymphoma (HL, n = 29), and chronic lymphocytic leukemia (CLL, n = 14), with 87% having advanced disease and 60% having experienced failure with a prior autologous transplant. Sixty-four percent of patients received a reduced-intensity conditioning regimen and 46% low-dose total-body irradiation (TBI). Median follow-up was 18 months. RESULTS Cumulative incidence of neutrophil engraftment was 84% by day 60, with greater engraftment in recipients of higher CD34(+) kg/cell dose (P = .0004). CI of non-relapse-related mortality (NRM) was 28% at 1 year, with a lower risk in patients treated with low-dose total-body irradiation (TBI; P = .03). Cumulative incidence of relapse or progression was 31% at 1 year, with a lower risk in recipients of double-unit UCBT (P = .03). The probability of progression-free survival (PFS) was 40% at 1 year, with improved survival in those with chemosensitive disease (49% v 34%; P = .03), who received conditioning regimens containing low-dose TBI (60% v 23%; P = .001), and higher nucleated cell dose (49% v 21%; P = .009). CONCLUSION UCBT is a viable treatment for adults with advanced lymphoid malignancies. Chemosensitive disease, use of low-dose TBI, and higher cell dose were factors associated with significantly better outcome.

Abstract
We determined treatment-related mortality, progression-free survival (PFS), and overall survival (OS) after a second autologous HCT (HCT2) for patients with lymphoma relapse after a prior HCT (HCT1). Outcomes for patients with either Hodgkin lymphoma (HL, n = 21) or non-Hodgkin lymphoma (NHL, n = 19) receiving HCT2 reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) were analyzed. The median age at HCT2 was 38 years (range: 16-61) and 22 (58%) patients had a Karnofsky performance score <90. HCT2 was performed >1 year after HCT1 in 82%. The probability of treatment-related mortality at day 100 was 11% (95% confidence interval [CI], 3%-22%). The 1-, 3-, and 5-year probabilities of PFS were 50% (95% CI, 34%-66%), 36% (95% CI, 21%-52%), and 30% (95% CI, 16%-46%), respectively. Corresponding probabilities of survival were 65% (95% CI, 50%-79%), 36% (95% CI, 22%-52%), and 30% (95% CI, 17%-46%), respectively. At a median follow-up of 72 months (range: 12-124 months) after HCT2, 29 patients (73%) have died, 18 (62%) secondary to relapsed lymphoma. The outcomes of patients with HL and NHL were similar. In summary, this series represents the largest reported group of patients with relapsed lymphomas undergoing SCT2 following failed SCT1, and with long-term follow-up. Our series suggests that SCT2 is feasible in patients relapsing after prior HCT1, with a lower treatment-related mortality than that reported for allogeneic transplant in this setting. HCT2 should be considered for patients with relapsed HL or NHL after HCT1 without alternative allogeneic stem cell transplant options.

Abstract
Allogeneic hematopoietic cell transplantation (alloHCT) represents the only curative therapy for several hematologic malignancies, and shows promise as a nascent treatment modality for select solid tumors. Although the original goal of alloHCT was hematopoietic reconstitution after sub-lethal chemoradiotherapy, recognition of a profound donor lymphocyte-mediated graft-versus-leukemia (GVL) or graft-versus-tumor (GVT) effect has shifted the paradigm from pre-transplant cytoreduction to tumor control via donor lymphocytes. In human leukocyte antigen (HLA)-compatible alloHCT, GVL and GVT reactions are induced primarily by donor T-cell recognition of minor histocompatibility antigens (mHAgs). Here we review the literature regarding mHAg-specific T cells in GVL and GVT reactions, and discuss the prospects of exploiting mHAgs as immunotherapeutic targets.

Abstract
BACKGROUND Constituting approximately 30% of lymphoid malignancies, diffuse large B-cell lymphoma (DLBCL) is the most common aggressive lymphoma in adults worldwide. The clinical and biologic heterogeneity that exists in DLBCL suggests that this entity might actually be comprised of several distinct neoplasms that could require different therapeutic approaches. DLBCL was considered incurable until combination chemotherapy became available. OBJECTIVE Current treatment strategies for the treatment of untreated and relapsed advanced-stage DLBCL are reviewed; novel treatments for DLBCL are discussed. METHODS Relevant literature was identified using the PubMed search engine and by reviewing abstracts from major conference proceedings. RESULTS/CONCLUSION Recently, novel therapeutic strategies, including the incorporation of immunotherapy to combination chemotherapy, have improved outcome for patients with DLBCL with cure rates exceeding 50%, especially in younger patients.

Abstract
We compared the outcomes of 141 consecutive patients who received allogeneic transplantation with either myeloablative (MA) or nonmyeloablative/reduced intensity (NMA) conditioning for non-Hodgkin and Hodgkin lymphoma at the University of Minnesota. All patients were transplanted between 1997 and 2004. NMA transplant recipients were older and received umbilical cord blood grafts more frequently (MA: 6 [9%]; NMA: 33 [43%], P < .001). NMA patients had more advanced disease and 30 (39%) patients had undergone prior autologous transplantation. The 4-year overall survival (OS) (MA: 46% versus NMA: 49%; p = .34) and the 3-year progression-free survival (PFS) (MA: 44% versus NMA: 31%; P = 0.82) were similar after MA or NMA conditioning. However, MA conditioning resulted in significantly higher 1-year treatment-related mortality (TRM) (MA: 43% versus NMA: 17%; P < .01) but a lower risk of relapse at 3 years (MA: 11% versus NMA: 36%; P < .01). We conclude that similar transplant outcomes are achieved after allogeneic hematopoietic stem cell transplantation using MA conditioning in younger patients and NMA conditioning in older patients or those with prior autologous transplantation not eligible for MA conditioning. Modifications to refine patient assignment to the preferred conditioning intensity and reduce relapse risks with NMA approaches are needed.

Abstract
Allogeneic hematopoietic SCT (HSCT) can ideally provide long-term remission in advanced lymphoma patients by capturing a graft-vs-tumor (GVT) effect. On the basis of a murine model, we attempted to optimize a GVT effect through nonmyeloablative therapy and HLA-matched related donor HSCT with intentional induction of mixed chimerism followed by prophylactic donor lymphocyte infusion. A total of 26 advanced lymphoma patients were separated into an early and late full-donor chimerism (FDC) group using a median of 45 days post-HSCT as the defining point for FDC. Upon generating these groups, analysis by Student's t-test demonstrated that they were statistically distinct in time to develop FDC (P<0.01). There was a trend toward improved CR rates in the late group relative to the early group (62 vs 31%; P=0.12). A trend toward improved progression-free survival at 5 years was also observed in the late compared to the early group by Kaplan-Meier analysis (38 vs 8%; P=0.081). However, this did not correlate to a significant overall survival benefit. In conclusion, these data support the observation from our mouse models that the most potent GVT effect occurs in mixed chimeras with late chimerism conversion.

Abstract
Nonmyeloablative stem cell transplantation in patients with follicular lymphoma has been designed to exploit the graft-versus-lymphoma immunity. The long-term effectiveness and toxicity of this strategy, however, is unknown. In this prospective study, we analyzed our 8-year experience. Patients received a conditioning regimen of fludarabine (30 mg/m(2) daily for 3 days), cyclophosphamide (750 mg/m(2) daily for 3 days), and rituximab (375 mg/m(2) for 1 day plus 1000 mg/m(2) for 3 days). They were then given an infusion of human leukocyte antigen-matched hematopoietic cells from related (n = 45) or unrelated donors (n = 2). Tacrolimus and methotrexate were used for graft-versus-host disease (GVHD) prophylaxis. Forty-seven patients were included. All patients experienced complete remission, with only 2 relapses. With a median follow-up time of 60 months (range, 19-94), the estimated survival and progression-free survival rates were 85% and 83%, respectively. All 18 patients who were tested and had evidence of JH/bcl-2 fusion transcripts in the bone marrow at study entry experienced continuous molecular remission. The incidence of grade 2-IV acute GVHD was 11%. Only 5 patients were still undergoing immunosuppressive therapy at the time of last follow-up. We believe that the described results are a step forward toward developing a curative strategy for recurrent follicular lymphoma.

Abstract
BACKGROUND Elderly and medically infirm cancer patients are increasingly offered allogeneic nonmyeloablative hematopoietic cell transplantation (HCT). A better understanding of the impact of health status on HCT outcomes is warranted. Herein, a recently developed HCT-specific comorbidity index (HCT-CI) was compared with a widely acceptable measure of health status, the Karnofsky performance status (KPS). METHODS The outcomes of 341 patients were evaluated, conditioned for either related or unrelated HCT by 2-gray (Gy) total body irradiation given alone or combined with fludarabine at a dose of 90 mg/m(2). Comorbidities were assessed retrospectively by the HCT-CI. Performance status before and toxicities after HCT were graded prospectively using the KPS and National Cancer Institute Common Toxicity criteria, respectively. RESULTS Weak Spearman rank correlations were noted between HCT-CI and KPS and between the 2 measures and age, number of prior chemotherapy regimens, and intervals between diagnosis and HCT (all r < 0.20). High-risk diseases correlated significantly with higher mean HCT-CI scores (P = .009) but not low KPS (P = .37). In multivariate models, the HCT-CI had significantly greater independent predictive power for toxicities (P = .004), nonrelapse mortality (P = .0002), and overall mortality (P = .0002) compared with the KPS (P = .05, .13, and .05, respectively). Using consolidated HCT-CI and KPS scores, patients were stratified into 4 risk groups with 2-year survivals of 68%, 58%, 41%, and 32%, respectively. CONCLUSIONS HCT-CI and KPS should be assessed simultaneously before HCT. The use of both tools combined likely refines risk-stratification for HCT outcomes. Novel guidelines for assessment of performance status among HCT patients are warranted.

Abstract
Bone marrow engraftment studies are used to evaluate the level of donor versus recipient cells in post-transplant peripheral blood or bone marrow specimens. Unique fingerprints identified from recipient and donor DNA are used to determine the proportion of each contained within the total DNA extracted from the post-transplant specimen. These percentages correspond to relative amounts of donor and recipient cells in the specimen. Engraftment studies are sequentially performed on transplant patients to closely monitor the levels of donor and recipient cells so that appropriate therapeutic intervention can proceed if and when needed. This unit will describe the use of fluorescent PCR for amplification of genomic short tandem repeats (STR). STR analysis is now considered the gold standard for engraftment studies and provides a quick and accurate assessment of the contribution of both donor and/or recipient hematopoietic cells in post-transplantation specimens.

Abstract
Radioimmunotherapy (RIT) combines the mechanism of action and targeting capability of monoclonal antibodies with the tumoricidal effect of radiation and has shown promising results in the treatment of various hematologic malignancies. Based on RIT's efficacy and safety profile, many investigators have evaluated its use in transplant conditioning regimens with the goal of improving long-term disease control with limited toxicity. In lymphoma, two basic transplant approaches targeting CD20 have emerged: (1) myeloablative doses of RIT with or without chemotherapy, and (2) standard nonmyeloablative doses of RIT combined with high-dose chemotherapy. Myeloablative RIT has been shown to be feasible and efficacious using escalated doses of iodine 131-tositumomab, yttrium 90-ibritumomab tiuxetan, and (131)I-rituximab with or without chemotherapy followed by autologous stem cell transplant (ASCT). The second approach predominantly has used standard doses of (90)Y-ibritumomab tiuxetan or (131)I-tositumomab plus BEAM chemotherapy (carmustine [BCNU], etoposide, cytarabine, melphalan) followed by ASCT. RIT targeting CD45, CD33, and CD66 prior to allogeneic transplantation also has been evaluated for the treatment of acute leukemia. Overall RIT-based transplant conditioning for lymphoma and leukemia has been shown to be safe, effective, and feasible with ongoing randomized trials currently underway to definitively establish its place in the treatment of hematologic malignancies.

Abstract
Follicular lymphomas constitute approximately 30% of all non-Hodgkin lymphomas. These lymphomas are characterized by at least partially follicular growth pattern, but diffuse areas may be present. The proportions of follicular or diffuse areas vary also from case to case, which seems to be associated with prognosis. Follicular lymphomas should not be divided into distinct subtypes, but rather shows a continuous gradation in the number of large cells. On the bases of this grading, three groups have been defined: grades 1-3. There is a consensus that grade 3 follicular lymphomas, namely grade 3b, should be discriminated from lower-grade cases. The cells of follicular lymphomas express surface immunoglobulin, more frequently IgM+/-IgD>IgG>IgA, B-cell-associated antigens, CD10+/-; they are CD5-, CD23-/+, CD43-, and CD11c-. Follicular lymphomas express bcl-2 proteins, which is useful in distinguishing reactive from neoplastic follicles. t(14;18) is present in 70-95% of follicular lymphomas, involving rearrangement of bcl-2 gene. Clinical behavior of follicular lymphomas is heterogeneous and differs according to the histologic grade and extension of disease. Moreover, the evaluation of these malignancies is conditioned by therapeutic decision, which is also determined by main prognostic factors. The International Prognostic Index for aggressive lymphomas is not optimal for follicular lymphomas. Conversely, the Italian Lymphoma Intergroup Index and, more recently, the Follicular Lymphoma International Prognostic Index (FLIPI), designed in pre-rituximab era, seem to correlate well with outcome. Several active therapeutic approaches from the "wait and watch" strategy to the allogeneic transplantation are available for management of patients with follicular lymphoma. Therapeutic decision is mostly conditioned by patient's characteristics, stage, histologic grade, tumor burden, and risk-predicting factors.

Abstract
Purpose Few effective treatment options exist for chemotherapy-refractory indolent or transformed non-Hodgkin's lymphoma (NHL). We examined the outcome of nonmyeloablative allogeneic hematopoietic cell transplantation (HCT) in this setting. Patients and Methods Sixty-two patients with indolent or transformed NHL were treated with allogeneic HCT from related (n = 34) or unrelated (n = 28) donors after conditioning with 2 Gy of total-body irradiation with or without fludarabine. Nine unrelated donors were mismatched for ≥ one HLA antigen. Sixteen patients had histologic transformation before HCT. Twenty patients (32%) had progressive disease after previous high-dose therapy with autologous HCT. Median age was 54 years, and patients had received a median of six lines of treatment before HCT. Median follow-up time after HCT was 36.6 months. Results At 3 years, the estimated overall survival (OS) and progression-free survival (PFS) rates were 52% and 43%, respectively, for patients with indolent disease, and 18% and 21%, respectively, for patients with transformed disease. Patients with indolent disease and related donors (n = 26) had 3-year estimated OS and PFS rates of 67% and 54%, respectively. The incidences of grade 2 to 4 acute graft-versus-host disease (GVHD), grade 3 and 4 acute GVHD, and extensive chronic GVHD were 63%, 18%, and 47%, respectively. Among survivors, the median Karnofsky performance status at last follow-up was 85%. Conclusion Nonmyeloablative allogeneic HCT can produce durable disease-free survival in patients with relapsed or refractory indolent NHL, even in this relatively elderly and heavily pretreated cohort. Outcomes were particularly good in patients with untransformed disease and related donors, whereas patients with transformed disease did poorly. Long-term survivors reported good overall functional status.

Comparable outcomes after nonmyeloablative hematopoietic cell transplantation with unrelated and related donors. Biol Blood Marrow Transplant 2008; 13:1499-507.

Abstract
We sought to determine whether patients with hematologic malignancies treated by nonmyeloablative hematopoietic cell transplantation (HCT) at a single institution between December 1997 and June 2006 had worse outcomes with grafts from unrelated donors (URDs) (n = 184) compared with HLA-identical related donors (n = 221). The nonmyeloablative preparative regimen consisted of 2 Gy of total body irradiation (TBI) with (78%) or without (22%) fludarabine, along with posttransplantation mycophenolate mofetil (MMF) and cyclosporine (CSa). After adjusting for the HCT comorbidity index, relapse risk, patient age, stem cell source, preparative regimen, previous cytomegalovirus (CMV) infection, and sex mismatch of donor and recipient in multivariate analysis, we found no statistically significant differences between unrelated and related HCT recipients in terms of risk of nonrelapse mortality (NRM; hazard ratio [HR] = 0.98; 95% confidence interval = 0.6-1.6; P = .94), relapse (HR = 1.04; 95% confidence interval = 0.7-1.5; P = .82), or overall mortality (HR = 0.99; 95% confidence interval = 0.7-1.4; P = .94). Overall rates of severe acute and extensive chronic graft-versus-host disease (aGVHD, cGVHD) also were not significantly different between the 2 groups. We conclude that within the limitations of a retrospective study, these results indicate that candidates for nonmyeloablative HCT without suitable related donors may expect similar outcomes with grafts from URDs.

Abstract
Outcomes of hematopoietic cell transplantation are steadily improving. New techniques have reduced transplant toxicities, and there are new sources of hematopoietic stem cells from unrelated donors. In June 2007 the Blood and Marrow Transplant Clinical Trials Network convened a State of the Science Symposium of more than 200 participants in Ann Arbor to identify the most compelling clinical research opportunities in the field. This report summarizes the symposium's discussions and identifies eleven high priority clinical trials that the network plans to pursue over the course of the next several years.

Abstract
Allogeneic conventional hematopoietic cell transplantation (HCT) can be curative treatment for lymphoid malignancies, but it has been characterized by high nonrelapse mortality (NRM). Here, we compared outcomes among patients with lymphoma or chronic lymphocytic leukemia given either nonmyeloablative (n = 152) or myeloablative (n = 68) conditioning. Outcomes were stratified by the HCT-specific comorbidity index. Patients in the nonmyeloablative group were older, had more previous treatment and more comorbidities, more frequently had unrelated donors, and more often had malignancy in remission compared with patients in the myeloablative group. Patients with indolent versus aggressive malignancies were equally distributed among both cohorts. After HCT, patients without comorbidities both in the nonmyeloablative and myeloablative cohorts had comparable NRM (P = .74), overall survival (P = .75), and progression-free survival (P = .40). No significant differences were observed (P = .91, P = .89, and P = .40, respectively) after adjustment for pretransplantation variables. Patients with comorbidities experienced lower NRM (P = .009) and better survival (P = .04) after nonmyeloablative conditioning. These differences became more significant (P < .001 and .007, respectively) after adjustment for other variables. Further, nonmyeloablative patients with comorbidities had favorable adjusted progression-free survival (P = .01). Patients without comorbidities could be enrolled in prospective randomized studies comparing different conditioning intensities. Younger patients with comorbidities might benefit from reduced conditioning intensity.

Abstract
Allogeneic hematopoietic cell transplantation (HCT) after nonmyeloablative conditioning for hematologic malignancies depends on graft-versus-tumor effects for eradication of cancer. Here, we estimated relapse risks according to disease characteristics. Between 1997 and 2006, 834 consecutive patients (median age, 55 years; range, 5-74 years) received related (n = 498) or unrelated (n = 336) HCT after 2 Gy total body irradiation alone (n = 171) or combined with fludarabine (90 mg/m(2); n = 663). Relapse rates per patient year (PY) at risk, corrected for follow-up and competing nonrelapse mortality, were calculated for 29 different diseases and stages. The overall relapse rate per PY was 0.36. Patients with chronic lymphocytic leukemia (CLL) and multiple myeloma (MM) in remission (CR), low-grade or mantle cell non-Hodgkin lymphoma (NHL) (CR + partial remission [PR]), and high-grade NHL-CR had the lowest rates (0.00-0.24; low risk). In contrast, patients with advanced myeloid and lymphoid malignancies had rates of more than 0.52 (high risk). Patients with lymphoproliferative diseases not in CR (except Hodgkin lymphoma and high-grade NHL) and myeloid malignancies in CR had rates of 0.26-0.37 (standard risk). In conclusion, patients with low-grade lymphoproliferative disorders experienced the lowest relapse rates, whereas patients with advanced myeloid and lymphoid malignancies had high relapse rates after nonmyeloablative HCT. The latter might benefit from cytoreductive treatment before HCT.

Abstract
BACKGROUND We previously showed that antithymocyte globulin (ATG) given with total body irradiation (TBI) 200 cGy and fludarabine results in high rate of donor engraftment. Its influence on acute and chronic graft versus host disease (GVHD) and on graft versus tumor effect is less known. METHODS Sixty-five patients underwent nonmyeloablative stem cell transplant with ATG, TBI 200 cGy, and fludarabine. GVHD prophylaxis was mycophenolate mofetil and cyclosporine. Forty-two patients (pts) (65%) had match related donors, 18 (27%) match unrelated, 1 (1.5%) mismatch related, and 4 (6%) mismatch unrelated donors. RESULTS At a median follow-up of 862 days, 24 patients (37%) developed GVHD. The median age of the patients with and without GVHD was 56 years respectively. Acute GVHD grade II-IV developed in 19 pts (29%). Fatal GVHD of liver and/or gut occurred in nine pts (14%). Forty-one pts survived more than 100 days. Five pts (12%) had chronic GVHD, two had extensive, and three had limited involvement. Relapsed disease was observed in 22 pts (34%). Infections occurred in 15 pts (23%) and were fatal in 13 (20%). CONCLUSIONS The addition of ATG to TBI 200cGy and fludarabine resulted in a modest incidence of GVHD. The best transplant outcomes were observed in pts with lymphoid malignancies.
