Abstract
Hematopoietic tissue-derived cells, including stem cells, have been shown to generate solid organ tissue-specific cells. Besides bone marrow and peripheral blood, umbilical cord blood (UCB) has the advantage of being an easily accessible stem cell source provided as a banked cell product. Using the xenogeneic human into NOD/SCID mouse stem cell transplant model preliminary data suggest UCB-derived tissue-specific cells generated in liver, pancreas, CNS and endothelium. In a clinical sex-mismatched UCB transplant setting Y-positive, UCB-derived gastrointestinal epithelial cells and CNS-specific cells have been identified in female patients. The potential therapeutic use of UCB cells for tissue repair is, however, limited by a low total stem cell number available and by HLA-disparity.

Abstract
Clinical outcomes were evaluated in 89 consecutive patients with multiple myeloma that had not responded to dexamethasone-based primary therapy, who received early intensive therapy supported by autologous stem cell transplantation. Results were compared with those of 45 comparable patients who refused or were unable to receive intensive treatment for socioeconomic reasons. Following high-dose therapy, the response rate was 69% including 16% with CR. Survival of 14 patients with CR (median >7.0 years) was significantly longer than those of 47 patients with PR (median 4.5 years) or of 28 patients who remained NR (median 2.2 years). CR occurred in 43% of patients with serum myeloma protein <1.5 gm/dl, in contrast to 7% of those with higher values, a finding similar to that observed previously for patients consolidated in PR. No prognostic factor was associated with PR and, in view of the high frequencies of PR or CR, all patients with primary resistant myeloma should be considered for early intensive therapy. The limited improvement of lifespan and disease-free survival for those in PR indicated the need for further treatment to achieve CR, the major surrogate marker for long survival.

Abstract
High-dose chemotherapy (HDC) followed by autologous stem cell transplantation (ASCT) improves survival in myeloma (MM). The role of induction therapy on outcomes of ASCT in MM has not been systematically studied. Nonmyelosuppressive (NMS) steroid-based induction can be used in MM, with the potential of reducing neutropenias and other toxic effects prior to ASCT. NMS induction however could be associated with poorer outcomes if disease control or stem cell collection were inadequate. We studied outcomes of 136 MM patients who underwent HDC and ASCT as part of their initial therapy between March 1998 and December 2000. Of these, 46 received HDC and ASCT without any exposure to myelosuppressive agents, 39 received myelosuppressive therapy for disease control and/or stem cell collection, and 51 received alkylating agent-based initial treatment. We compared OS and EFS rates, stem cell collectability, and contamination of the grafts with monoclonal plasma cells. After a median of 33 months, response rates, EFS and OS rates were comparable in the three groups of patients. Adequacy of stem cell collection and plasma cell contamination were similar. Our data support the hypothesis that NMS induction for patients with MM is safe and effective and does not compromise the results of HDC.

Abstract
Recently, adult stem cells originating from bone marrow or peripheral blood have been suggested to contribute to repair and genesis of cells specific for liver, cardiac and skeletal muscle, gut, and brain tissue. The mechanism involved has been termed transdifferentiation, although other explanations including cell fusion have been postulated. Using adult stem cells to generate or repair solid organ tissue obviates the immunologic, ethical, and teratogenic issues that accompany embryonic stem cells.

Abstract
Donor lymphocyte infusions (DLIs) are an effective treatment for relapsed Chronic myeloid leukemia (CML) after allogeneic transplantation but are limited by the occurrence of GVHD. CD8+ T lymphocytes are involved in the pathogenesis of GVHD but may not be essential for the graft-versus-leukemia (GVL) effect in CML. We have treated 26 CML patients with posttransplantation relapse with CD8-depleted DLI. Thirteen of 15 patients (87%) who relapsed in early-phase CML achieved complete cytogenetic response, but only 1 of 11 who relapsed in advanced-phase disease achieved complete response. Acute GVHD occurred in 2 patients (8%), and extensive chronic GVHD occurred in 2 patients (11%). Treatment-related mortality was 11.5%. Responses were durable; with a median follow-up of 4.2 years (1-7.5 years), only 1 responding patient relapsed (7%). CD8-depleted DLI was equally effective and safe after unrelated donor transplants and sibling transplants. Cytogenetic clonal evolution at the time of DLI was not predictive of treatment failure unless associated with hematologic criteria for disease acceleration. CD8 depletion is an effective method to separate GVL from GVHD for posttransplantation relapsed CML. This strategy is associated with durable complete remissions and a low rate of complications and therefore merits further investigation in larger-scale comparative trials.

Abstract
We conducted a retrospective analysis of all allogeneic stem cell transplantation (ASCT) patients started on extracorporeal photopheresis (ECP) for the management of steroid-dependent (SD) or steroid-refractory (SR) cutaneous chronic graft-versus-host disease (cGVHD) following ASCT during a 36-month period (9/98-8/01). Only SD or SR patients who were treated by ECP after day 100 and who received at least 4 weeks of ECP were considered evaluable for this analysis. Out of 64 ASCT patients reviewed, 32 patients met the inclusion criteria. All 32 patients had been previously treated with systemic corticosteroids with 11 (34%) being SR and 21 (66%) SD. Cutaneous cGVHD was extensive in 28 patients (88%) and was accompanied by visceral (hepatic, gastrointestinal) cGVHD in 23 patients (72%). The 32 evaluated patients had received a median of three prior therapies before ECP, most commonly systemic corticosteroids, tacrolimus, and mycophenolate mofetil. Patients received a median of 36 ECP sessions (range 12-98) over a median of 5.3 months (range 1-28), with a median of six sessions per month. The complete response (CR) rate was 22% (n=7) and the partial response rate was 34% (n=11). In all, 28 patients were on systemic corticosteroid therapy at ECP initiation and 18 patients achieved 50% dose reduction while on ECP, yielding a 64% steroid-sparing response rate. Of seven CRs, five are ongoing. A total of 11 (34%) patients have died after ECP, with all cases due to visceral cGVHD or cGVHD-related infectious complications. All 21 surviving patients remain on at least some immunosuppressive cGVHD therapy (including ECP in eight). Overall, ECP displays a substantial response rate and, in particular, steroid-sparing activity in SR/SD extensive cutaneous cGVHD. However, most patients continue to require at least some chronic therapy and cGVHD-related morbidity and mortality remain high.

Abstract
Real-time RT-PCR has great advantages for estimating transcript levels in a variety of situations. These include relative rapid assay times (hours), reliability and ease of performing replicate analyses. In contrast, competitive PCR is a very labor-intensive procedure requiring a few days to generate useful data. We compared the same samples from CML patients by both methods. Importantly, we used the Bcr-Abl junction plasmid DNA, which is used as a competitor in the manual competitive PCR assay, to generate a standard curve for the real-time assay. This permitted reporting the real-time data as the number of BCR-ABL transcripts per microg of total RNA, which is the same format used for the competitive PCR assay. In this study, a total of 435 peripheral blood and marrow samples from 285 CML patients were analyzed by RT-PCR; these patients were undergoing therapy by STI-571, interferon, and bone marrow transplantation treatment. Most samples also had assay values for the Philadelphia chromosome (Ph), FISH and Western blotting for the Bcr-Abl oncoprotein. Our findings indicated that the real-time assay was less sensitive than the manual competitive RT-PCR assay (t = 5.118; P < 0.001). Of interest, the transcript levels in cell line mixtures with various ratios of K562/KG-1 (BCR-ABL positive/negative) cells were also significantly higher with the competitive RT-PCR assays than real-time RT-PCR, except for levels of BCR-ABL below 200 transcripts per microg of RNA. In both patient and cell line experiments, dividing the BCR-ABL transcripts by the total ABL transcripts virtually eliminated the difference between real-time BCR-ABL transcript values and quantitative competitive BCR-ABL transcript values, indicating that both BCR-ABL and ABL transcripts were underestimated by the real-time assay. In addition, the increased sensitivity of the nested, competitive RT-PCR was readily apparent in patients with minimal residual disease, which by the real-time were negative in the majority of patients but were positive by nested, competitive RT-PCR in 44.6% (n = 29) of samples analyzed (n = 65). These findings indicate that real-time RT-PCR, when normalized for the total ABL transcripts, can be used to monitor CML patients during therapy, but we suggest that nested, competitive RT-PCR be used to determine BCR-ABL/ABL transcript ratios at low transcript values or especially when real-time analyses are negative.

Abstract
Graft-versus-host disease (GVHD) remains a major complication of allogeneic hematopoietic stem cell transplantation. Polymyositis can occur in association with chronic GVHD and mimics the idiopathic form of the disease. We report two cases of chronic GVHD-associated polymyositis and review the published literature. The two patients presented 13 and 19 months after allogeneic transplantation with characteristic features of muscular hypotrophy, proximal muscle weakness, pain, elevated creatine phosphokinase (CPK), aldolase and SGPT. Interestingly, both patients had HLA DR52 genes, which is frequently reported in association with idiopathic polymyositis. Electromyogram (EMG) and muscle biopsy confirmed the diagnosis. Treatment with cyclosporine or tacrolimus resulted in complete and sustained remission of polymyositis in both cases. A review of the literature shows cyclosporine and steroids are well-described treatment options for patients with myositis in post transplant, as well as idiopathic cases. The duration of immunosuppressive treatment has varied in different reports, and there is a risk of recurrence when immunosuppression is tapered.

Abstract
The purpose of the study was to determine the feasibility and efficacy of a reduced intensity conditioning regimen of fludarabine and melphalan for allogeneic transplantation in patients with multiple myeloma. From August 1996 to December 2000, 22 patients received a reduced intensity conditioning regimen with fludarabine and melphalan. Median age was 51 years (range, 45-64), median time from initial therapy to transplant was 36 months (range, 3-135 months). Disease phase prior to transplant was primary refractory in two patients, refractory relapse in 11 patients, sensitive relapse in eight patients and initial remission consolidation in one patient. The median number of prior therapies was five (range, 1-7), and median beta 2 microglobulin prior to transplant was 3.0 mg/l (range, 1.0-7.3). All patients received unmanipulated grafts from either HLA matched sibling donors (n = 13) or matched unrelated donors (n = 9). Eighteen patients received fludarabine 30 mg/m(2) for 4 days with melphalan 140 mg/m(2) as a single dose and four patients received fludarabine 25 mg/m(2) for 5 days with melphalan 90 mg/m(2) daily for 2 days. All 21 patients evaluable for engraftment achieved a neutrophil count of >0.5 x 10(9)/l after a median of 12 days (range, 9-24), 18 patients achieved platelet transfusion independence after a median of 14 days (range, 8-47). All engrafting patients had 100% donor cell engraftment. Seven patients achieved a complete remission. Six patients are currently alive with a median follow-up of 15 months (range, 10-47 months). The actuarial survival and progression-free survival is 30 +/- 11% and 19 +/- 9% at 2 years. Non-relapse mortality at 100 days was 19 +/- 10% and 40 +/- 10% at 1 year. Fludarabine/melphalan combinations are feasible and allow consistent engraftment of allogeneic progenitor cells from both related and unrelated donors in patients with multiple myeloma and should be explored in patients with less advanced disease.

Abstract
BACKGROUND Some transplant-related complications, such as the engraftment syndrome, are thought to be mediated by cytokines released during expansion of hematopoietic progenitors at the time of neutrophil recovery. Since there is an inverse correlation between CD34(+) cell dose and time to neutrophil recovery, we sought to determine if peritransplant toxicity and early mortality were adversely affected by high CD34(+) cell doses. METHODS The study group included 186 women with breast cancer who received high-dose cyclophosphamide, carmustine, thiotepa and an autologous PBSC transplant. The median CD34(+) cell dose was 5.9 x 10(6)/kg (1.0-154.7 x 10(6)/kg). Patients were categorized by CD34(+) cell dose (1.0-3.5, 3.6-5.9, 6.0-19.9, and 20.0-154.7 x 10(6)/kg) for assessment of outcomes. RESULTS Grades 2-4 mucositis occurred in 49%, cardiac toxicity in 7%, pulmonary toxicity in 5%, cystitis in 4%, diarrhea in 3%, renal toxicity in 1%, and central nervous system toxicity in 1%. A Grade 2-4 regimen-related toxicity occurred in 109 patients (59%) and Grade 3-4 in eight patients (4%). Overall survival was 100% at Day 30, 96% at Day 90, and 89% at 1 year. Treatment-related mortality was 3.8%. In multivariate analyses that included prior chemotherapy, disease status, visceral metastases, prior chest radiation and age, CD34(+) cell dose group was not an independent risk factor for Grade 2-4 mucositis, Grade 2-4 maximum toxicity, Grade > or =3 cumulative toxicity, 90 day survival or 1 year survival. DISCUSSION We conclude that CD34(+) cell doses >20 x 10(6)/kg do not affect transplant outcome in a negative or positive fashion.

Abstract
Human leukemia-derived dendritic cells show potential as tools for therapy. Leukemic cells of patients with chronic myelogenous leukemia (CML), acute myelogenous leukemia (AML), and chronic myelomonocytic leukemia (CMML) will all undergo substantial differentiation toward dendritic cells (DC) and may be used to drive autologous T cells to acquire anti-leukemic cytotoxicity. This article describes the use of these human leukemia-derived dendritic cells for stimulation of allogeneic donor lymphocytes and presents a clinical trial of autologous CML DC-stimulated lymphocytes.

Abstract
Donor lymphocyte transfusion has gained considerable interest as adoptive cellular immunotherapy for prevention or treatment of relapse after allogeneic stem cell transplantation. This study was designed to compare the yield of CD3(+), CD3(+)4(+), CD3(+)8(+), CD19(+), CD3(-)56(+)16(+), and CD34(+) cells contained in apheresis products from 61 consecutive non-cytokine treated, human leukocyte antigen (HLA)-matched donors for lymphocyte collection with the corresponding apheresis-derived cell yield from 112 consecutive, HLA-matched donors for blood stem cell collection who received recombinant human granulocyte colony stimulating factor (rhG-CSF, filgrastim) 6 microg/kg every 12 hours until cell collection was completed. Apheresis was started on day 4 or 5 of rhG-CSF treatment. The yield of lymphoid subsets was significantly different in the two sample groups, rhG-CSF treated product yields exceeding untreated product yields by a median of 2.1-fold (range: 1.3-2.6). However, the CD34(+) cell yield in rhG-CSF-treated apheresis products exceeded untreated products by 26-fold. A single untreated apheresis procedure was usually sufficient to collect a target dose of 1 x 10(8)/kg CD3(+) cells. Untreated apheresis products contained a median of 0.2 x 10(6)/kg CD34(+) cells. A potential engraftment dose of > or =0.5 x 10(6) CD34(+) cells per kg of recipient body weight was contained in 16% of 57 untreated apheresis products. One single apheresis performed in a normal, untreated donor provides a sufficient amount of CD3(+) cells for adoptive immunotherapy. Compared with that of an rhG-CSF stimulated apheresis product, the CD34(+) cell count is usually, but not always, below the engraftment dose range. RhG-CSF treatment has little effect on the yield of lymphoid subsets collected by apheresis but is highly selective of the release of CD34(+) cells. This report provides baseline data for studies that will show whether other cytokines such as granulocyte macrophage colony stimulating factor (GM-CSF) and/or Flt-3 Ligand can immunomodulate allotransfusates in vivo to improve the graft-vs.-leukemia (GVL) effect after allogeneic stem cell transplantation, while lowering the incidence and severity of graft-vs.-host disease (GVHD).
