Abstract
Allogeneic hematopoietic stem cell transplantation (HSCT) is one of curative treatment options for patients with hematologic malignancies. Although GVHD mediated by the donor's T lymphocytes remains the most challenging toxicity of allo-HSCT, graft-versus-leukemia (GVL) effect targeting leukemic cells, has an important role in affecting the overall outcome of patients with AML. Here we comprehensively characterized the TCR repertoire in patients who underwent matched donor or haplo-cord HSCT using next-generation sequencing approach. Our study defines the functional kinetics of each TCRA and TCRB clone, and changes in T-cell diversity (with identification of CDR3 sequences) and the extent of clonal expansion of certain T-cells. Using this approach, our study demonstrates that higher percentage of cord-blood cells at 30 days after transplant was correlated with higher diversity of TCR repertoire, implicating the role of cord-chimerism in enhancing immune recovery. Importantly, we found that GVHD and relapse, exclusive of each other, were correlated with lower TCR repertoire diversity and expansion of certain T-cell clones. Our results highlight novel insights into the balance between GVHD and GVL effect, suggesting that higher diversity early after transplant possibly implies lower risks of both GVHD and relapse following the HSCT transplantation.

Abstract
We describe treatment, outcomes and prognostic factors for patients who relapse following transplantation with a reduced intensity conditioning regimen. Seventy consecutive patients with high-risk myeloid malignancies underwent transplant and 25 (36%) relapsed, a median of 120 days later. The median percentage of bone marrow blasts at relapse was 24, the median donor chimerism was 73% and new karyotypic abnormalities occurred in 8 out of 20 (40%) evaluable patients. Twenty-one patients (84%) received aggressive treatment for relapse, including chemotherapy (60%), second hematopoietic cell transplantation (HCT; 52%) and/or donor lymphocyte infusion (DLI; 12%). Thirteen achieved a complete response (CR) and four remain in CR. Median overall survival (OS) after relapse was 6 months (95% confidence interval=2.7-9.9 months), and actuarial 1 year OS was 24%. Most deaths were due to disease progression (17/20, 85%). We did not observe an advantage for cellular therapy (DLI or second transplant) compared to chemotherapy. Salvage therapy for relapse after reduced intensity HCT is feasible, associated with low treatment-related mortality, and may result in prolonged survival in select patients. Studies exploring the optimal treatment for relapse following reduced intensity HCT are warranted.

Abstract
7088 Background: DNA hypermethylation of promoter-specific CpG islands has been implicated in the pathogenesis and progression of disease in MMM. We are evaluating Decitabine, a DNA methyltransferase inhibitor in patients (pts) with MMM. Methods: This is a single stage Phase II trial: planned accrual of 20 pts. Pts had to have MMM with anemia and/or splenomegaly. Decitabine is given subcutaneously (SQ) at a dose of 0.3 mg/kg/d on days 1–5, and days 8–12; cycles are repeated every 6 weeks, in the absence of dose limiting toxicities. Response is determined every 12 weeks as an improvement in cytopenias and/or splenomegaly. CD34+ cells are measured by flow cytometry in peripheral blood at baseline, and at days 5 and 12 of therapy; elevated levels are associated with advanced stage and evolution to blast phase in MMM. Results: Pt characteristics: M/F: 6/4, median age 67 (range 42–89), median absolute CD34+ cell count 116 × 106/L (11–4,959), Dupriez score of 2, 1 and 0 in 50%, 30% and 20% respectively. Median number of cycles administered: 3 (range 1- 9). Median WBC and platelet (plt) count: 5.2 K/uL (1.5–29), and 171 K/uL (47–465 K/uL); 5 pts were red cell transfusion dependent. Grade 4 neutropenia (ANC) occurred in all pts, and grade 3/4 plts in 6 pts. 7 pts have developed febrile neutropenia. Grade 3–4 non-hematologic toxicities include a variceal bleed in a patient with baseline portal hypertension and a splenic infarct occurring in another pt. 7 pts are evaluable for response: 3 pts have responded including 1 pt with a CR (normalization of blood counts and transfusion independence), and 1 pt with a PR (Hb increase of > 2 g/dL). A third pt in the blast phase of the disease had a hematological improvement as evidenced by a normalization in plts (from 62 K/uL to 219 K/uL) associated with a significant decrease (from 2.58 K/uL to 0.03 K/uL) in circulating blasts. The other 4 pts have had stable disease. There was a reduction in CD34+ levels: mean decrease of approximately 75% at day 12 of therapy (p<0.0001). Conclusions: Low dose SQ decitabine is feasible in MMM and is associated with a significant decrease in CD34+ cells. There is preliminary evidence of clinical activity. Myelosupression is significant, though reversible and requires close monitoring. These findings must be validated in a larger group of pts.

Abstract
BACKGROUND Because of high single-agent activity and modest toxicity, we hypothesized the combination of gemcitabine (G), vinorelbine (V), and pegylated liposomal doxorubicin (D) would be an effective salvage therapy for Hodgkin's lymphoma (HL). PATIENTS AND METHODS A total of 91 patients participated. GVD was administered on days 1 and 8 every 21 days at doses of G 1000 mg/m(2), V 20 mg/m(2), and D 15 mg/m(2) for transplant-naive patients, and G 800 mg/m(2), V 15 mg/m(2), and D 10 mg/m(2) for post-transplant patients. RESULTS The dose-limiting toxicity was mucositis for the transplant-naive patients and febrile neutropenia for post-transplant patients. The overall response rate (RR) for all patients was 70% [95% confidence interval (CI) 59.8, 79.7], with 19% complete remissions. The 4-year event-free and overall survival rates in transplant-naive patients treated with GVD followed by autologous transplant were 52% (95% CI 0.34, 0.68) and 70% (95% CI 0.49, 0.84), and in the patients in whom prior transplant failed, these were 10% (95% CI 0.03, 0.22) and 34% (95% CI 0.17, 0.52), respectively. CONCLUSIONS GVD is a well-tolerated, active regimen for relapsed HL with results similar to those reported for more toxic regimens. High RRs in patients in whom prior transplant failed confirms this regimen's activity even in heavily pretreated patients.

Abstract
Alemtuzumab (Campath-1H)-based conditioning regimens are effective in preventing GVHD, but are associated with very high rates of cytomegalovirus (CMV) infection, a major limitation to their use. We evaluated 85 patients receiving conditioning with fludarabine 30 mg/m2/day (day -7 to day -3), alemtuzumab 20 mg/day (day -7 to day -3), and melphalan 140 mg/m2 on day -2. The initial patients received post transplant CMV prophylaxis with high-dose acyclovir. A very high incidence of CMV viremia was observed as has been commonly reported after alemtuzumab-based conditioning. Sixty-seven subsequent patients received pre-transplant ganciclovir and high-dose valacyclovir after engraftment. The cumulative incidence of CMV infection in the valacyclovir cohort was 29%. This compared favorably to the cumulative incidence of 53% in patients receiving only acyclovir (P = 0.004) and to literature data. CMV prophylaxis with pre-transplant ganciclovir and high-dose valacyclovir after engraftment appears effective in preventing the excessive incidence of CMV infection after alemtuzumab-based conditioning regimens.

Abstract
The impact of disease burden on the outcome of patients with acute myeloid leukemia (AML) undergoing allogeneic stem cell transplantation (SCT) has not been well defined. Data from several retrospective series suggest that overt leukemia at the time of transplant increases the risk of relapse. We reviewed the outcomes of 68 consecutive adults with AML (n=60) or myelodysplastic syndromes (MDS) (n=8) who received an allogeneic SCT at the University of Chicago between May 1986 and October 2002 to confirm the importance of currently recognized risk factors for overall survival (OS) and progression-free survival (PFS). In addition, we wanted to determine whether quantification of residual disease by blast percentage or cytogenetic abnormalities at the time of SCT was correlated with outcome. AML subtypes based on the FAB classification were as follows: M0=9, M1=9, M2=16, M3=2, M4=16, M5=3, M6=5. Cytogenetic analysis was available from 52 patients. Using standard morphologic criteria, 34 patients were in complete remission (CR) and 34 had visible leukemia present. The majority of donors were HLA-identical siblings (n=55). In all, 56 patients received myeloablative conditioning regimens and 12 received a reduced-intensity, fludarabine-based conditioning regimen. OS and PFS times were 7.1 months (95% CI, 4.8-10.4) and 5.1 months (95% CI, 3.2-7.8), respectively. Median follow-up from SCT was 4.6 years (range, 0.6-17.0) for survivors. In multivariate analysis, the following factors were found to be associated with worse survival: (1) increased percentage of blasts in the bone marrow at the time of SCT, (2) presence of acute graft-versus-host disease, (3) mismatched donor, (4) Zubrod performance score of >/=2, and (5) age >/=45 years. We also found a trend towards improved outcome among patients in cytogenetic remission as compared to those who had residual cytogenetic abnormalities and those in overt relapse. These data support an association between pre-transplant disease burden and poor outcome after SCT.

Abstract
Our purpose was to study the risk factors associated with disease progression after high-dose chemotherapy followed by autologous stem cell transplantation in patients with recurrent or refractory Hodgkin's lymphoma (HL). We analyzed the long-term outcome of 184 patients with recurrent or refractory HL who underwent autologous hematopoietic stem cell transplantation. At the time of transplantation, 82 patients were in first relapse or second remission, 46 patients were refractory to the primary induction chemotherapy, and 56 patients were beyond first relapse or second remission. In 64 patients, the disease had proved refractory to the chemotherapy regimen administered immediately prior to transplantation. The median follow-up of patients who were alive and free of disease at the time of this report was 8.9 years (range, 0.1-19.0 years). At 10 years, the overall and disease-free survival rates were 34% (95% CI 27-42) and 29% (95% CI 22-36) respectively. The major cause of treatment failure was disease relapse. Chemotherapy resistance prior to transplantation, advanced stage, and higher number of chemotherapy regimens administered prior to transplantation were adverse prognostic factors for disease progression. We conclude that autologous transplantation is an effective salvage treatment for recurrent HL.

Abstract
Fludarabine, thiotepa and total body irradiation (TBI) has been used as conditioning in haplo-identical transplantation. We studied this conditioning regimen in adults undergoing matched sibling transplantation and alternative donor transplantation. A total of 30 consecutive patients underwent matched related, haplo-identical related or matched unrelated donor transplantation with fludarabine, thiotepa and TBI conditioning. All but four had advanced hematologic malignancies. For haplo-identical transplant, ATG was added to the regimen. All patients received peripheral blood stem cells; these were T-cell depleted for 2-antigen or 3-antigen mismatched related transplantation. Additional graft-versus-host disease prophylaxis consisted of tacrolimus and mini-methotrexate. One recipient of haplo-identical transplant failed to engraft; all other evaluable patients had prompt engraftment. Four patients died of regimen-related toxicity. In all, 14 additional patients died of regimen-related causes including four from failure to thrive with persistent thrombocytopenia and four from delayed pulmonary toxicity. Six patients relapsed. Progression-free survival at 12 months was 47% (90% CI: 25-69%) for recipients of HLA-identical sibling transplants and 30% (90% CI: 14-46%) for all patients. Five of six long-term survivors have extensive chronic GVHD. As a result of the delayed complications and a relatively high recurrence rate, we abandoned this regimen.

Abstract
To establish the incidence of CMV viremia after allogeneic blood stem cell transplantation, we studied 51 consecutive allogeneic peripheral blood stem cell (PBSC) transplant recipients. A total of 12 recipients were at moderate risk for CMV disease and 39 were at high risk. Conditioning regimens varied, but GvHD prophylaxis consisted of tacrolimus and mini-methotrexate in all patients. All patients received prophylactic ganciclovir from admission until day -2 and prophylactic acyclovir from day -1 until day 180 after transplantation. CMV viremia was treated with ganciclovir. Using a PCR-based technique, the cumulative incidence of CMV viremia was 31+/-14% by day 100 and 35+/-14% by day 150. Donor type, CMV risk group, underlying disorder, conditioning regimen, GvHD, and steroid use were not associated with the risk for CMV viremia. No cases of CMV disease occurred. We hypothesize that the low rate of CMV viremia and the absence of CMV disease in this cohort of PBSCT transplant recipients, which contrasts with other reports, may be related to the prophylactic use of high-dose acyclovir and possibly to pretransplant use of ganciclovir.

Abstract
BACKGROUND Intermediate- and high-grade NHL are generally chemosensitive diseases with high initial response rates to combination chemotherapy. Dose intensification via autologous and allogeneic transplantation provides viable treatment options in specific clinical settings. Currently, autologous transplantation is the standard of care for relapsed but chemosensitive aggressive B-cell NHL. However, tools such as the International Prognostic Index allow risk-adapted analyses, and show that the magnitude of benefit from autologous transplantation differs in lymphoma subsets. METHODS Low-risk patients appear to do well regardless of salvage approaches, whereas high-risk patients have suboptimal outcomes with autologous transplantation. In high-risk patients, high-dose chemotherapy with autologous stem-cell transplantation has been examined as part of initial therapy, with long-term data promising but still evolving. DISCUSSION A significant concern with autologous transplantation in aggressive and high-grade NHL is the risk of graft contamination with tumor cells. Several investigators have demonstrated the presence of malignant cells in both BM and PBSC, although the clonagenic potential of such cells is unclear. Allogeneic stem-cell transplantation has several potential advantages over autologous transplantation for NHL,including procurement of an uncontaminated stem-cell graft, GvL effects, and the elimination of hematopoietic stem-cell damage and consequent secondary leukemia. RESULTS The ideal application of allogeneic transplantation in aggressive and high-grade lymphomas is still unclear; but the lower relapse rates demonstrated in several comparisons of the two approaches make this an exciting area to pursue. Finally, non-myeloablative stem-cell transplantation may broaden the use of allogeneic transplantation by lowering regimen-related mortality while capitalizing on GvL.

Abstract
The incidence, characteristics, risk factors for, and impact of chronic graft-vs-host disease (GVHD) were evaluated in a consecutive series of 116 evaluable HLA-identical blood stem cell transplant recipients. Minimum follow-up was 18 months. Limited chronic GVHD occurred in 6% (95% confidence interval [CI], 0%-13%), and clinical extensive chronic GVHD in 71% (95% CI, 61%-80%). The cumulative incidence was 57% (95% CI, 48%-66%). In univariate analyses, GVHD prophylaxis other than tacrolimus and methotrexate, prior grades 2 to 4 acute GVHD, use of corticosteroids on day 100, and total nucleated cell dose were significant risk factors for clinical extensive chronic GVHD. On multivariate analysis, GVHD prophylaxis with tacrolimus and methotrexate was associated with a reduced risk of chronic GVHD (hazard ratio [HR], 0.35; P =.001), whereas the risk was increased with prior acute GVHD (HR, 1.67; P =.046). When adjusted for disease status at the time of transplantation, high-risk chronic GVHD had an adverse impact on overall mortality (HR, 6.6; P <.001) and treatment failure (HR, 5.2; P <.001) at 18 months. It was concluded that there is a substantial rate of chronic GVHD after HLA-identical allogeneic blood stem cell transplantation, that clinical factors may alter the risk of chronic GVHD, and that high-risk chronic GVHD adversely affects outcome.

Allogeneic stem cell transplantation for sickle cell disease. A study of patients' decisions. Bone Marrow Transplant 2001; 28:545-9. [PMID: 11607766 DOI: 10.1038/sj.bmt.1703208] [Citation(s) in RCA: 60] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2001] [Accepted: 07/06/2001] [Indexed: 11/09/2022]
Abstract
Allogeneic stem cell transplantation is increasingly considered as a curative though risky treatment option for adults with sickle cell disease. Little is known about attitudes of adult patients and their health care providers regarding the risks and benefits of transplantation. A survey of 100 patients and their health care providers was undertaken. Assessment of risk was by a reference gamble paradigm. Comparison was made of the characteristics of those accepting substantial risk vs those not accepting risk, as well as assessment of agreement on risks recommended by health care providers and accepted by patients. Sixty-three of 100 patients were willing to accept some short-term risk of mortality in exchange for the certainty of cure. Fifteen patients were willing to accept more than 35% mortality risk. No differences in patient or disease-related variables were identified between those accepting risk and those not accepting risk. There was no agreement between the recommendations of health care providers and the risk accepted by patients. A substantial proportion of adults with sickle cell disease are interested in curative treatment, at the expense of considerable risk. The decision to accept risk is influenced by individual patient values that cannot be easily quantified and that do not correlate with the assessment of the health care provider. Given the substantial interest in curative therapy, education about and consultation for allogeneic stem cell transplantation in sickle cell patients should be encouraged.

Abstract
Autologous and allogeneic transplantation are increasingly used in the management of patients with chronic lymphocytic leukemia. Many questions regarding patient selection, efficacy and outcome are unresolved, hence a review of the literature through Medline search. Autologous transplantation for CLL has been used mainly in selected patients under the age of 60. Conditioning typically involves total body irradiation (TBI). Bone marrow and more recently peripheral blood stem cells are used. Treatment-related mortality in most series is less than 10%. Molecular remissions after autologous transplantation are common, and clinical remissions can be prolonged in some patients. Randomized studies are needed to establish whether autologous transplantation confers a survival benefit over standard chemotherapy approaches. Allogeneic transplantation has a considerable treatment-related mortality, but durable remissions sometimes occur in patients with advanced disease. The use of non-myeloablative 'mini-transplants' has been investigated as a method to reduce treatment-related mortality, but prolonged follow-up will be required to establish the cure rate obtained with this procedure. Autologous and allogeneic transplantation are promising treatment modalities. Further refinements of transplant techniques and properly designed prospective studies are necessary to establish the role of stem cell transplantation in the overall management of CLL.

Fludarabine and melphalan-based conditioning for patients with advanced hematological malignancies relapsing after a previous hematopoietic stem cell transplant. Bone Marrow Transplant 2001; 28:557-62. [PMID: 11607768 DOI: 10.1038/sj.bmt.1703198] [Citation(s) in RCA: 33] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2001] [Accepted: 06/11/2001] [Indexed: 11/09/2022]
Abstract
Severe regimen-related toxicity often complicates second transplant procedures performed in patients with hematological malignancies that have relapsed after an initial hematopoietic stem cell (HSC) transplant. Therefore, we studied the safety and efficacy of a reduced-intensity fludarabine and melphalan based conditioning regimen in 11 patients who had relapsed following an autologous (n = 7) or allogeneic (n = 4) HSC transplant. All patients received allogeneic peripheral blood HSC from either an HLA-identical (n = 7) or an HLA-mismatched (n = 4) relative. Diagnoses included AML (n = 9), ALL (n = 1), or Hodgkin's disease (n = 1). Only one patient was in complete remission at the time of second transplant. The median interval between first transplant and relapse was 163 days (range 58-1885). Recipients of HLA-mismatched transplants received antithymocyte globulin in addition to fludarabine and melphalan as part of the conditioning regimen. All 11 patients received acute GVHD prophylaxis consisting of tacrolimus and methotrexate. Ten of 11 patients achieved hematopoietic engraftment with a median time to absolute neutrophil count >0.5 x 10(9)/l and to platelet count of >20 x 10(9)/l of 14 and 19 days, respectively. All engrafting patients achieved 100% donor chimerism on initial analysis, except for one with persistent leukemia at day +19. Two patients experienced grade 3 regimen-related toxicity, manifesting as acute renal failure. Acute GVHD grades 2-4 occurred in two recipients and chronic GVHD in four. The 100-day mortality from all causes was 36%. Ten of 11 patients (91%) died a median of 140 days (range 9-996) after the second transplant. The causes of death included relapse (n = 5), sepsis (n = 4), and idiopathic pneumonia syndrome (n = 1). One patient with AML survives in remission at 880 days post-transplant. We conclude that fludarabine- and melphalan-based conditioning promotes full donor chimerism, even following HLA-mismatched transplants. However, the regimen may be more beneficial when applied to patients undergoing allogeneic HSC transplantation earlier in their disease course.

Abstract
Sixty-two adults underwent marrow or blood stem cell transplantation from an HLA-matched related donor using high-dose thiotepa, busulfan, and cyclophosphamide (TBC) as the preparative regimen for treatment of advanced myelodysplastic syndrome (MDS) (refractory anemia with excess blasts with or without transformation) or acute myelogenous leukemia (AML) past first remission. All evaluable patients engrafted and had complete donor chimerism. A grade 3-4 regimen-related toxicity occurred in eight (13%) patients, and a diagnosis of MDS was the only independent risk factor for grade 3-4 regimen-related toxicity (hazard ratio 9.25, P = 0.01). Day-100 treatment-related mortality (TRM) was 19%. Poor-prognosis cytogenetics increased the risk of day-100 TRM (hazard ratio 11.4, P = 0.003), and use of tacrolimus for graft-versus-host disease prophylaxis reduced the risk of day-100 TRM (hazard ratio 0.13, P = 0.027). For all patients, the three-year relapse rate was 43% (95% CI, 28%-58%). Refractoriness to conventional induction chemotherapy prior to transplantation was an independent risk factor for relapse (hazard ratio 10.8, P = 0.02). Three-year survival was 26% (95% CI, 14%-37%); survival rates were 29% for those transplanted for AML in second remission, 31% transplanted for AML in relapse, and 17% with MDS, and there were no independent risk factors for survival. TBC is an active preparative regimen for advanced AML. Patients with advanced MDS appeared to have a higher risk of toxicity and early mortality, and alternative preparative regimens should be considered for these patients.

Abstract
PURPOSE Primary mediastinal B-cell lymphoma (PMBL) is recognized as a separate disease entity in the REAL classification. There is uncertainty about the relevance and especially the optimal management of this disorder. In this review, we discuss clinical presentation, pathology, pathobiology, and management of PMBL in order to provide a platform for initiation of further clinical and biologic studies. MATERIALS AND METHODS Studies were identified through a MEDLINE search and from the bibliographies of relevant articles. RESULTS PMBL is a tumor of young adults who present with a rapidly proliferating tumor. At diagnosis, the tumor is usually limited to intrathoracic organs. Spread to parenchymal organs such as liver, kidneys, and CNS is common at recurrence. Fibrosis and the presence of so-called clear cells are distinctive morphologic features of PMBL, although they are not pathognomonic or even necessary for diagnosis. On the other hand, biologic features relating to oncogene rearrangement and overexpression as well as cytogenetic features clearly differentiate PMBL from other types of diffuse large B-cell lymphoma. Phase II studies and retrospective series indicate cure rates that range from 38% to 88%. The role of chemotherapy, radiation, and high-dose chemotherapy with stem cell rescue in the management of PMBL is reviewed. CONCLUSION PMBL has unique clinical and biologic characteristics that are radically different from those of other types of diffuse large B-cell lymphoma. Although relatively rare, its aggressive growth and its occurrence in young patients increase the clinical relevance of this entity. The consistent recognition and study of PMBL will allow the development of new approaches to its management.

Abstract
PURPOSE To evaluate whether administration of interleukin-2 (IL-2) with granulocyte colony-stimulating factor (G-CSF) improves mobilization of immune effector cells into the stem-cell graft of patients undergoing high-dose chemotherapy and autografting. PATIENTS AND METHODS We performed a trial of stem-cell mobilization with IL-2 and G-CSF in advanced breast cancer patients receiving high-dose chemotherapy with cyclophosphamide, thiotepa, and carboplatin and stem cells followed by IL-2. The trial defined immune, hematologic, and clinical effects of IL-2 in this setting. RESULTS Of 32 patients enrolled, nine received G-CSF alone for mobilization. Twenty-one of 23 patients mobilized with IL-2 plus G-CSF had stem cells collected with more mononuclear cells than those receiving G-CSF (19.3 v 10.4 x 10(8)/kg; P =.006), but fewer CD34(+) progenitor cells (6.9 v 22.0 x 10(6)/kg; P =.049). The IL-2 plus G-CSF-mobilized patients had greater numbers of activated T (CD3(+)/CD25(+)) cells (P =.009), natural killer (NK; CD56(+)) cells (P =.007), and activated NK (CD56 bright(+)) cells (P: =.039) than those patients mobilized with G-CSF. NK (P =.042) and lymphokine-activated killer (LAK) (P =.016) activity was increased in those mobilized with IL-2 + G-CSF, whereas G-CSF-mobilized patients had a decline in cytolytic activity. In the third week posttransplantation, immune reconstitution was superior in those mobilized with IL-2 plus G-CSF based on greater numbers of activated T cells (P =.003), activated NK cells (P =.04), and greater LAK activity (P =.003). The 16 of 21 IL-2 + G-CSF-mobilized patients with adequate numbers of stem cells (> 1.5 x 10(6) CD34(+) cells/kg) collected engrafted rapidly posttransplantation. CONCLUSION The results demonstrate that G-CSF + IL-2 can enhance the number and function of antitumor effector cells in a mobilized autograft without impairing the hematologic engraftment, provided that CD34 cell counts are more than 1.5 x 10(6) cells/kg. Mobilization of CD34(+) stem cells does seem to be adversely affected. In those mobilized with IL-2 and G-CSF, post-stem-cell immune reconstitution of antitumor immune effector cells was enhanced.

Autotransplants for Hodgkin's disease in first relapse or second remission: a report from the autologous blood and marrow transplant registry (ABMTR). Bone Marrow Transplant 2001; 27:387-96.

Abstract
Although patients with relapsed Hodgkin's disease have a poor prognosis with conventional therapies, high-dose chemotherapy and autologous hematopoietic stem cell transplantation (autotransplantation) may provide long-term progression-free survival. We reviewed data from the Autologous Blood and Marrow Transplant Registry (ABMTR) to determine relapse, disease-free survival, overall survival, and prognostic factors in this group of patients. Detailed records from the ABMTR on 414 patients with Hodgkin's disease in first relapse (n = 295) or second complete remission (CR) (n = 119) receiving an autotransplant from 1989 to 1995 were reviewed. Median age was 29 (range, 7-64) years. Median time from diagnosis to relapse was 18 (range, 6-219) months; median time from relapse to transplant was 5 (range, <1-215) months. Most patients received high-dose chemotherapy without total body irradiation for conditioning (n = 370). The most frequently used high-dose regimen was cyclophosphamide, BCNU, VP-16 (CBV) (n = 240). The graft consisted of bone marrow (n = 246), blood stem cells (n = 112), or both (n = 56). Median follow-up was 46 (range, 5-96) months. One hundred-day mortality (95% confidence interval) was 7 (5-9)%. One hundred and sixty-five of 295 patients (56%) transplanted in relapse achieved CR after autotransplantation. Of these, 61 (37%) recurred. Twenty-four of 119 patients (20%) transplanted in CR recurred. The probability of disease-free survival at 3 years was 46 (40-52)% for transplants in first relapse and 64 (53-72)% for those in second remission (P < 0.001). Overall survival at 3 years was 58 (52-64)% after transplantation in first relapse and 75 (66-83)% after transplantation in second CR (P < 0.001). In multivariate analysis, Karnofsky performance score <90% at transplant, abnormal serum LDH at transplant, and chemotherapy resistance were adverse prognostic factors for outcome. Progression of Hodgkin's disease accounted for 69% of all deaths. Autotransplantation should be considered for patients with Hodgkin's disease in first relapse or second remission. Future investigations should focus on strategies designed to decrease relapse after autotransplantation, particularly in patients at high risk for relapse.

Phase II study of a high-dose ifosfamide-based chemotherapy regimen with growth factor rescue in recurrent aggressive NHL. High response rates and limited toxicity, but limited impact on long-term survival. Bone Marrow Transplant 2001; 27:397-404.

Abstract
The purpose of the study was to evaluate in patients with recurrent intermediate-grade NHL, the tolerance to and efficacy of an intensive salvage regimen consisting of high doses of ifosfamide, etoposide and mitoxantrone with G-CSF support, followed by autologous stem cell transplantation and to identify prognostic factors for survival in patients with recurrent aggressive lymphoma. Patients with recurrent intermediate-grade NHL under the age of 60 years were eligible. Induction consisted of ifosfamide 10 g/m(2) and etoposide 900 mg/m(2) with G-CSF 5 microg/kg twice a day. Upon recovery, patients underwent stem cell apheresis. Patients achieving complete remission (CR) underwent autologous stem cell transplantation using BEAM conditioning. Those with partial remission (PR) received treatment with ifosfamide 10 g/m(2), mitoxantrone 20 mg/m(2) and G-CSF 5 microg/kg. Those with CR received BEAM, those with PR received cyclophosphamide 4.5 g/m(2), etoposide 1200 mg/m(2) and cisplatin 135 mg/m(2) with stem cell rescue followed by BEAM. Antibiotic prophylaxis was given with all treatment cycles. The results were compared with those obtained in a prior study that used MINE-ESHAP salvage. Forty-four patients with recurrent intermediate-grade NHL were enrolled between March 1994 and September 1996. Median age was 50 years (24-61). Eleven patients had transformed lymphoma and seven had a T cell phenotype. Response rate to the high-dose ifosfamide regimen was 77% +/- 12% after two cycles and the complete response rate was 41% +/- 14%. Myelosuppression was profound but short. Median nadir ANC was 0 and the median duration of ANC <0.5 x 10(9)/l was 6 days (range 3-12). No severe infections occurred; 55% of the patients required blood transfusion and 42% required platelet transfusions. Myelosuppression and transfusion requirements were similar after the first and second cycles. Thirty-five of the 44 patients proceeded to autologous stem cell transplantation and one transplant-related death occurred. With a median follow-up of 52 months, progression-free survival at 2 years is 38% +/- 14% and survival is 52% +/- 15%. Data from these 44 patients were pooled with data on 53 patients who had received salvage treatment with MINE-ESHAP, for a multivariate analysis of prognostic factors. In multivariate analysis, serum LDH was strongly associated with survival. The use of a more intensive salvage regimen, did not result in a significant increase in long-term outcome, despite a high response rate. In conclusion, duration of treatment, response rates, treatment-related mortality and survival compare favorably with previous salvage regimens, but recurrence remains a major problem. Long-term survival in recurrent large cell lymphoma is influenced more by disease characteristics than by the type of salvage regimen used.

Abstract
PURPOSE To evaluate the results of high-dose chemotherapy and autologous hematopoietic stem-cell transplantation (autotransplants) in patients with diffuse aggressive non-Hodgkin's lymphoma (NHL) who never achieve a complete remission with conventional chemotherapy. PATIENTS AND METHODS Detailed records from the Autologous Blood and Marrow Transplant Registry (ABMTR) on 184 patients with diffuse aggressive NHL who never achieved a complete remission with conventional chemotherapy and subsequently received an autotransplant were evaluated. Transplants were performed between 1989 and 1995 and were reported to the ABMTR by 48 centers in North and South America. RESULTS Seventy-nine (44%) of 184 patients achieved a complete remission or a complete remission with residual imaging abnormalities of unknown significance after autotransplantation. Thirty-four (19%) of 184 had a partial remission and 55 (31%) of 184 had no response or progressive disease. Eleven patients (6%) were not assessable for response because of early death. The probabilities of progression-free and overall survival at 5 years after transplantation were 31% (95% confidence interval [CI], 24% to 38%) and 37% (95% CI, 30% to 45%), respectively. In multivariate analysis, chemotherapy resistance, Karnofsky performance status score less than 80 at transplantation, age > or = 55 years at transplantation, receiving three or more prior chemotherapy regimens, and not receiving pre- or posttransplant involved-field irradiation therapy were adverse prognostic factors for overall survival. CONCLUSION High-dose chemotherapy and autologous hematopoietic stem-cell transplantation should be considered for patients with diffuse aggressive NHL who never achieve a complete remission but who are still chemotherapy-sensitive and are otherwise transplant candidates.

Abstract
One hundred patients of median age 34 years (range, 14-53) received bone marrow transplants from unrelated donors serologically matched for human leukocyte antigen HLA-A, HLA-B, and HLA-DR using tacrolimus and minimethotrexate for prevention of acute graft-versus-host disease (GVHD). Sixty-eight patient-donor pairs had allelic matches at HLA-DRB1 and HLA-DQB1, 20 pairs had a single mismatch at HLA-DRB1 or HLA-DQB1, and 12 were mismatched at both HLA-DRB1 and HLA-DQB1. Minimum follow-up time was 6 months. Grades 2 to 4 GVHD occurred in 43% of patients with matched donors, 69% with single allele-mismatched donors, and 71% with double allele-mismatched donors; grades 3 to 4 GVHD occurred in 22%, 43%, and 64%, respectively. On multivariate analysis, the relative risk of grades 2 to 4 GVHD was 2.2 (95% CI, 1.1-4.5; P = .03) with a single allele mismatch and 2.7 (95% CI, 1.2-6.0; P = .02) with a double allele mismatch. The relative risks of grades 3 to 4 GVHD were 3.0 (95% CI, 1.2-7.6; P = .02) and 5.0 (95% CI, 1.9-12.6; P = .001), respectively. Day 100 treatment-related mortality was also adversely affected by allelic mismatching, occurring in 21% of those with matched donors, 50% with single allele-mismatched donors, and 42% with double allele-mismatched donors (P = .02), but overall survival at day 180 did not differ significantly among the 3 groups. Tacrolimus does not abrogate the adverse impact of allele mismatching at HLA-DRB1 and HLA-DQB1 on the risk of moderate-to-severe acute GVHD.

Abstract
Although allogeneic transplantation can be curative for patients with sickle cell disease, the toxicity of conditioning regimens has precluded its use in adults with significant end-organ damage. Newer conditioning regimens have been developed that are less toxic and that may broaden the applicability of allogeneic transplantation in this disorder. We report two adults with end-stage sickle cell disease, who underwent allogeneic transplantation from an HLA-identical sibling donor after conditioning with fludarabine/melphalan and ATG. Both patients had been extensively transfused and one had multiple RBC antibodies. One of the patients also had end-stage renal disease, and was dialysis dependent. Engraftment occurred promptly in both patients. Both achieved 100% donor chimerism and both were free of pain crises after transplant. The first patient died of a respiratory failure related to chronic graft-versus-host disease (GVHD) on day 335 after transplantation. The second patient developed severe gastro-intestinal GVHD and TTP and died on day 147 after transplantation. Conditioning with fludarabine/melphalan and ATG followed by allogeneic stem cell transplantation resulted in prompt and reliable engraftment in adults with end-stage sickle cell disease. The incidence of severe GVHD was unacceptably high and may be related to the ethnicity of the patients or to the inflammatory state associated with pre-existing sickle cell disease.

Abstract
Patients with acute leukemias relapsing within 1 year of an allogeneic BMT have a poor prognosis. We studied the use of melphalan 180 mg/m2 followed by allogeneic peripheral blood stem cells (PBSC) as salvage treatment for patients relapsing after related (n = 7) or matched unrelated transplants (n = 3). Diagnoses were AML (n = 4), ALL (n = 3), biphenotypic acute leukemia (n = 2) and CML in blast crisis (n = 1). Eight patients were beyond first relapse and none were in remission. The median time from previous transplant to relapse was 146 days (range 66-206). The melphalan dose was 90 mg/m2 intravenously on days -4 and -3 with PBSC infusion on day 0. GVHD prophylaxis consisted of cyclosporine and methylprednisolone. The median time to an absolute neutrophil count >0.5 x 10(9)/l and to a platelet count >20 x 10(9)/l was 11 and 13 days, respectively. All engrafting patients (n = 8) had 100% donor cells. Two patients died before day 30, but no other grade 3 or 4 toxicity occurred. Acute GVHD grades II-III occurred in two subjects, and chronic GVHD in four. Seven patients achieved CR, but relapsed at a median of 116 days (range 56-614). Leukemia was the cause of death in eight patients. Median survival was 149 days (range 6-614). This treatment produced responses in the majority of this poor prognosis group. However, durable remissions were not observed, and new treatments to consolidate the responses achieved in this setting are needed. This regimen could be considered for short-term disease control to facilitate donor lymphocyte infusion-based immunotherapy or other measures to prevent disease recurrence.

Abstract
Thirty adults with leukemia or lymphoma transplanted with marrow or blood stem cells from 1-antigen mismatched related donors received tacrolimus and minidose methotrexate to prevent acute graft-versus-host disease (GVHD). The group had a median age of 42 years (range 18-56 years). Twenty-seven patients had advanced disease, and 13 were resistant to conventional therapy. Tacrolimus was administered at 0.03 mg/kg/day i.v. by continuous infusion from day -2, converted to oral at four times the i.v. dose following engraftment, and continued to day 180 post-transplant. Methotrexate 5 mg/m2 was given i.v. on days 1, 3, 6 and 11. Mild nephrotoxicity was common before day 100; 69% of patients had a doubling of creatinine, 56% had a peak creatinine greater than 2 mg/dl, and two patients were dialyzed. Other toxicities prior to day 100 thought to be related to tacrolimus included hypertension (45%), hyperkalemia (17%), hyperglycemia (14%), seizures (13%), headache (3%) and hemolytic uremic syndrome (3%). Grades 2-4 GVHD occurred in 59% (95% CI, 38-70%), and grades 3-4 GVHD in 17% (95% CI, 1-32%). Overall survival at 1 year was 29% (95% CI, 12-45%). We conclude that tacrolimus and minidose methotrexate is active post-transplant immunosuppression for patients with 1-antigen mismatched donors.

Abstract
We evaluated demographic characteristics and graft composition as risk factors for acute graft-versus-host disease (GVHD) in 160 adult recipients of HLA-identical allogeneic blood stem cell transplants. The patients received a median nucleated cell dose of 7.9 x 10(8)/kg and median C34(+) cell dose of 5.6 x 10(6)/kg. GVHD prophylaxis consisted of cyclosporine (CSA) and steroids, tacrolimus (FK506) and steroids, or FK506 and methotrexate. Grades 2 to 4 GVHD occurred in 31% (95% CI, 23% to 39%), and grades 3 to 4 GVHD in 14% (95% CI, 8% to 20%). In univariate analyses, GVHD prophylaxis with CSA and high CD34(+) cell doses were significant risk factors for grades 2 to 4 GVHD, but diagnosis, age, use of total body irradiation, donor sex, female donor for male recipient, donor parity, donor alloimmunization, viral serology, nucleated cell dose, CD3(+) cell dose, and CD56(+) cell dose did not alter the incidence of GVHD significantly. With a CD34(+) cell dose less than 8 x 10(6) CD34(+) cells/kg, the risk of grades 2 to 4 GVHD was significantly higher for those who received CSA (39%, 95% CI, 21% to 47%) in comparison with those on FK506 (18%, 95% CI, 10% to 26%) (P =.03), but GVHD prophylaxis regimen had less impact with a higher CD34(+) cell dose (overall grades 2 to 4 GVHD rate 52%, 95% CI, 37% to 67%). GVHD prophylaxis and CD34(+) cell dose are independent risk factors for acute GVHD after allogeneic blood stem cell transplantation.

Abstract
Thirty-six adults with chronic myelogenous leukemia (CML) in second or greater chronic phase, accelerated phase, or blast crisis underwent marrow or blood stem cell transplantation from an HLA-matched sibling using high-dose thiotepa, busulfan and cyclophosphamide (TBC) as the preparative regimen. All evaluable patients engrafted and had complete donor chimerism. One patient failed to clear meningeal leukemia, and one patient had one of 30 metaphases positive for the Philadelphia chromosome at 2 months post transplant. The remainder of the patients studied had eradication of CML documented by cytogenetics and/or Southern blot for BCR gene rearrangement, and 13 of 15 patients studied became negative for the BCR gene rearrangement by polymerase chain reaction. Three-year relapse rate is 42% (95% CI, 19-64%). The relapse rate was significantly lower for patients transplanted without blast crisis (9% vs 100%, P < 0.001). Eight (22%, 95% CI, 10-39%) patients had severe or fatal veno-occlusive disease (VOD). Elevated liver enzymes within 1 month prior to transplantation and transplantation using marrow were significantly associated with the occurrence of VOD. Three-year survival is 28% (95% CI, 13-43%). Survival was significantly higher for patients transplanted without blast crisis (45% vs 0%, P = 0.01). TBC is an effective preparative regimen for CML in accelerated phase but not refractory blast crisis, and it should be used with caution in patients with prior hepatopathy who have an increased risk of severe VOD.

Abstract
BACKGROUND The combination of carmustine, etoposide, cytarabine and melphalan (BEAM) is an effective autologous transplantation preparative regimen for lymphoma and has little toxicity, but the feasibility and tolerance of BEAM as a preparative regimen for allogeneic transplantation has not been established. PATIENTS AND METHODS Thirty adults with primary refractory or recurrent intermediate- or low-grade lymphoma were treated on a prospective phase II study with carmustine 300 mg/m2 i.v. day -6, etoposide 200 mg/m2 i.v. followed by cytarabine 200 mg/m2 i.v. twice daily days -5 to -2, melphalan 140 mg/m2 i.v. day -1, and marrow or blood stem cells from an HLA-identical donor on day 0. Tacrolimus and methotrexate were used to prevent graft-vs.-host disease (GVHD). RESULTS Median time from transplantation was 20 mos (range 6-32 months). Median maximal regimen-related toxicity grade was 2, and four patients (13%) had a grade 3-4 regimen-related toxicity. Two patients had idiopathic interstitial pneumonitis. One patient had primary graft failure, and a second had autologous reconstitution documented at three months posttransplant. Grades 2-4 acute GVHD occurred in 31%, grades 3-4 in 16%, and chronic GVHD in 54%. Day-100 survival was 70%. Twenty-three patients achieved a complete response. The two-year relapse rate was 23%, survival was 48%, and disease-free survival (DFS) was 42%. CONCLUSIONS BEAM supports engraftment of allogeneic transplants and is a tolerable preparative regimen for allogeneic transplantation for lymphoma.

Abstract
PURPOSE Hodgkin's disease patients who never achieve complete remission with conventional chemotherapy (i.e., those with primary induction failure) have a poor prognosis. Some subjects who receive high-dose therapy with autologous hematopoietic progenitor-cell infusion experience prolonged progression-free survival. PATIENTS AND METHODS Detailed records from the Autologous Blood and Marrow Transplant Registry (ABMTR) on 122 Hodgkin's disease patients who failed to achieve complete remission after one or more conventional therapy regimens and subsequently received an autotransplant between 1989 and 1995 were reviewed. RESULTS Median age was 27 years (range, 7 to 57 years). Median time from diagnosis to transplantation was 14 months (range, 5 to 38 months). Most patients received high-dose chemotherapy without radiation for pretransplantation conditioning (n = 107). The regimen most frequently used was cyclophosphamide, carmustine, and etoposide (n = 47). Fifteen patients received total-body irradiation (n = 15). The graft consisted of bone marrow (n = 86), blood stem cells (n = 25), or both (n = 11). The 100-day mortality was 12% (95% confidence interval, 7% to 19%). Sixty patients (50%) were considered to have achieved complete remission after autotransplantation; 37 of these had negative imaging studies, whereas scan abnormalities of unknown significance persisted in 23 patients. Twenty-seven patients (22%) had no response or progressive disease after transplantation. Probabilities of progression-free and overall survival at 3 years were 38% (95% confidence interval, 28% to 48%) and 50% (95% confidence interval, 39% to 60%), respectively. In multivariate analysis, "B" symptoms at diagnosis and poor performance score at transplantation were adverse prognostic factors for outcome. CONCLUSION Autotransplants should be considered for patients with Hodgkin's disease who do not achieve complete remission with conventional therapy.

Allogeneic bone marrow transplantation for low-grade lymphoma. Blood 1998; 92:1832-6. [PMID: 9716615] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/08/2023] Open
Abstract
Advanced low-grade lymphomas are usually incurable with conventional-dose chemotherapy. It is uncertain whether cures are possible with high-dose therapy and bone marrow transplant from a human leukocyte antigen (HLA)-identical sibling. We sought to determine the outcome of HLA-identical sibling bone marrow transplants in advanced low-grade lymphoma in an observational study of 113 patients conducted at 50 centers participating in the International Bone Marrow Transplant Registry (IBMTR). The median patient age was 38 years (range, 15 to 61). Eighty percent had stage IV disease at the time of transplantation. The median number of prior chemotherapy regimens was two (range, 0 to 5). Thirty-eight percent had refractory disease and 29% a Karnofsky performance score (KPS) less than 80%. All patients underwent allogeneic bone marrow transplantation from a HLA-identical sibling donor. The conditioning regimen included total-body irradiation (TBI) in 82% of patients; cyclosporine was used for graft-versus-host disease prophylaxis in 74%. Survival, disease-free survival, recurrence rate, treatment-related mortality, and causes of death were determined. Three-year probabilities of recurrence, survival, and disease-free survival were 16% (95% confidence interval [CI], 9% to 27%), 49% (95% CI, 39% to 60%), and 49% (95% CI, 39% to 59%), respectively. Higher survival was associated with pretransplant KPS >/=90%, chemotherapy-sensitive disease, use of a TBI-containing conditioning regimen, and age less than 40 years. We conclude that high-dose therapy followed by transplantation from a HLA-identical sibling leads to prolonged survival in some patients with advanced low-grade lymphoma. Most mortality is treatment-related, and recurrences are rare.
