Abstract
Allogeneic transplantation of hematopoietic cells from an HLA-compatible donor has been used to treat hematologic malignancies. Allogeneic transplantation not only replaces the marrow affected by the disease, but exerts an immune graft-versus-tumor (GVT) effect mediated by donor lymphocytes. The development of nonmyeloablative conditioning regimens before allogeneic transplantation has allowed this therapy to be used in elderly and disabled patients. An allogeneic GVT effect is observed in a proportion of patients with renal, breast, colorectal, ovarian, and pancreatic cancer treated with allogeneic transplantation. In general, the tumor response is associated with the development of acute and chronic graft-versus-host disease. Further improvements will depend on the identification of the antigen targets of GVT, and on reduction of the toxicity of the procedure. Targeted therapies may complement the immune effect of allogeneic transplantation. We present updated results from the literature and data recently placed on file at the European Bone Marrow Transplantation Solid Tumors Working Party.

Abstract
We reviewed 66 women with poor-risk metastatic breast cancer from 15 centers to describe the efficacy of allogeneic hematopoietic cell transplantation (HCT). Median follow-up for survivors was 40 months (range, 3-64). A total of 39 patients (59%) received myeloablative and 27 (41%) reduced-intensity conditioning (RIC) regimens. More patients in the RIC group had poor pretransplant performance status (63 vs 26%, P=0.002). RIC group developed less chronic GVHD (8 vs 36% at 1 year, P=0.003). Treatment-related mortality rates were lower with RIC (7 vs 29% at 100 days, P=0.03). A total of 9 of 33 patients (27%) who underwent immune manipulation for persistent or progressive disease had disease control, suggesting a graft-vs-tumor (GVT) effect. Progression-free survival (PFS) at 1 year was 23% with myeloablative conditioning and 8% with RIC (P=0.09). Women who developed acute GVHD after an RIC regimen had lower risks of relapse or progression than those who did not (relative risk, 3.05: P=0.03), consistent with a GVT effect, but this did not affect PFS. These findings support the need for preclinical and clinical studies that facilitate targeted adoptive immunotherapy for breast cancer to explore the benefit of a GVT effect in breast cancer.

Abstract
The development of reduced intensity or non-myeloablative conditioning (NST) in preparation for allogeneic stem cell transplantation (SCT) revolutionized the field and led to reconsideration of the dogma of upper age limit that was set up by the transplant centers as an eligibility parameter. Analysis of the literature data showed that NST regimens are associated with decreased transplant related mortality, and graft-versus-host disease, in comparison with standard myeloablative conditioning, in patients above the age of 50-55 years, or in younger patients with significant comorbidities. However we have to mention, that our considerations are based on the retrospective analysis of the literature data, and that well controlled prospective randomized studies are needed in order to definitely assess the role of NST. Comorbidity indices might be proved as the most important parameters for the choice of the most proper regimen for each patient in need and should be included in future trials.

Abstract
The use of a mismatched allograft necessitates T cell depletion for prevention of uncontrolled graft-versus-host disease (GVHD), thus impairing a graft-versus-leukemia effect. Data on donor lymphocyte infusion (DLI) after mismatched stem cell transplantation are lacking. Our experience with 28 patients (treated with 59 mismatched DLIs; range, 1-7) is described. The procedure was prophylactic in 6 patients (9 DLIs) and therapeutic in 22 (50 DLIs). DLI dose ranged from 10(2) to 1.5 x 10(9) T cells/kg. In the 6 patients receiving prophylactic DLI, complete remission was maintained in 5; however, 2 died from GVHD. Clinical response to therapeutic DLI was seen in 6 of 22 (27.3%) patients; a greater tumor burden produced a lower response. GVHD appeared in 13 of 28 patients. Surprisingly, a greater HLA mismatch was associated with a lower risk of GVHD, with 3 of 19 DLIs in 3/6 matching and 16 of 29 DLIs in 5/6 matching with similar follow-up. Nevertheless, no correlation between efficacy and HLA mismatching was noted. Death was frequent and usually related to the basic disease rather than to DLI complications. We conclude that mismatched DLI is feasible and may be effective, especially if given soon after transplantation. Future developments using cell therapy with selective or targeted anticancer activity are warranted, with special attention to prophylactic treatment of T cell depleted mismatched allografts recipients.

Abstract
A trifunctional bispecific antibody (BiLu) directed against murine CD3 and human epithelial-cell adhesion molecule (EpCAM) was tested for its ability to improve cell-mediated adoptive immunotherapy in a murine model of B16 melanoma cells transfected with human EpCAM. Intraperitoneal inoculation of naive C57BL/6 (C57) splenocytes induced lethal graft versus host disease (GVHD) in 85% to 97% of sublethally irradiated (BALB/c × C57BL/6) F1 (F1) hosts inoculated intraperitoneally with a sublethal or lethal dose of melanoma cells. BiLu antibodies given intraperitoneally concomitantly with alloreactive C57 cells effectively prevented GVHD-related and tumor-related death in 16 of 25 F1 mice inoculated with a sublethal tumor-cell dose and in 10 of 20 mice inoculated with a lethal tumor-cell dose over a follow-up period of more than 200 days. BiLu treatment also efficiently prevented severe GVHD, which was induced by high doses of BALB/c-derived splenocytes. Trifunctional bispecific antibodies (TbsAbs) capable of cross-linking T lymphocytes, natural killer, and other FcγR-positive effector cells, via their Fc region, to the tumor cells may be applied together with adoptive allogeneic-cell therapy to maximize antitumor responses while acting on GVHD in patients with minimal residual disease.

Abstract
The conditioning prior to allogeneic stem cell transplantation was originally designed as a myeloablative conditioning, designed to eliminate malignant or genetically abnormal cells and then use the transplant procedure for rescue of the patients or to replace missing bone marrow products. However, allografts can induce effective graft vs. malignancy effects and can also eliminate undesirable hematopoietic stem cells in patients with genetic disorders and autoimmune diseases, thus documenting that alloreactive effects mediated by donor lymphocytes post-grafting can play a major role in eliminating hematopoietic cell of host origin, as well as provide effective immunotherapy for the treatment of disease recurrence. The efficacy of donor lymphocyte infusion (DLI) could be improved by activation with rIL-2 or by donor immunization. The cumulative experience over the years suggesting that alloreactive donor lymphocytes were most effective in eliminating tumor cells of host origin resulted in an attempt to reduce the intensity of the conditioning in preparation for the transplant procedure used for the treatment of hematological and other malignancies as well as life-threatening non-malignant disorders for which allogeneic stem cell transplantation may be indicated. Our working hypothesis proposed that the myeloablative conditioning which is hazardous and may be associated with early and late side effects, may not be required for treatment of patients with any indication for allogeneic stem cell transplantation. Instead, nonmyeloablative conditioning based on the use of reduced intensive preparatory regimen, also known as nonmyeloablative stem cell transplantation, may be sufficient for engraftment of donor stem cells while avoiding procedure-related toxicity and mortality, followed by elimination of undesirable cells of host origin by post-transplant effects mediated by alloreactive donor lymphocytes infused along with donor stem cells or administered subsequently as DLI. Improvement of the immediate outcome of stem cell transplantation using NST due to a significant decrease in transplant related mortality has broadened the spectrum of patients eligible for allogeneic stem cell transplantation, including elderly patients and other patients with less than optimal performance status. Likewise, the safer use of stem cell transplantation prompted expanding the scope of potential indications for allogeneic stem cell transplantation, such as metastatic solid tumors and autoimmune disorders, which now are slowly becoming much more acceptable. Current strategies focus on the need to improve the capacity of donor lymphocytes to eliminate undesirable malignant and non-malignant hematopoietic cells of host origin, replacing abnormal or malignant stem cells or their products with normal hematopoietic stem cells of donor origin, while minimizing procedure-related toxicity and mortality and improving the quality of life by reducing the incidence and severity of hazardous acute and chronic GVHD.

Abstract
We demonstrated previously that tumor lysate-pulsed dendritic cells (TP-DC) could mediate a specific and long-lasting antitumor immune response against a weakly immunogenic breast tumor during early lymphoid reconstitution. The purpose of this study was to examine the potential therapeutic efficacy of bone marrow transplants from TP-DC-vaccinated donors. In 2 aggressive metastatic models, bone marrow transplantation with donor bone marrow cells from TP-DC-immunized mice mediated a tumor-specific immune response in the recipient, and this caused regressions of preexisting tumor metastases. After vaccination with TP-DC, donors harbored increased numbers of both activated CD4+ and CD8+ T-cell populations in the bone marrow. Adoptive transfer of T cells purified from the bone marrow of TP-DC-vaccinated mice led to a reduction in preestablished lung metastases, whereas depletion of T cells from bone marrow abolished this effect. By using T cells derived from the bone marrow of TP-DC-vaccinated major histocompatibility complex class I and class II knockout mice, the effector cells required for the observed antitumor effect were determined to be major histocompatibility complex class I-restricted CD8+ T cells. Additionally, the tumor burden in TP-DC-immunized transplant recipients could be reduced further by repetitive TP-DC immunizations after bone marrow transplantation. Collectively, these results demonstrate an important therapeutic role of bone marrow from TP-DC-immunized donors and raise the potential for this approach in patients with advanced cancer.

Abstract
Nonmyeloablative stem cell transplantation (NST) and donor lymphocyte infusions (DLI) are currently under clinical investigation as an innovative therapeutic option for patients with metastatic renal cell carcinoma (RCC). The underlying concept, adopted from patients with hematologic malignancies, aims at a reduction of conditioning toxicity and exploits the graft versus malignancy effect of donor T-lymphocytes after transplantation. Clinical data from more than 100 patients treated worldwide have been published so far. The data provide evidence that NST is feasible with a very low rate of engraftment failure. Objective remissions in these heterogenous studies were observed in 23% of the patients overall. Remissions after NST developed only after complete engraftment of donor lymphoid cells had occurred. Objective responses were almost always accompanied by graft versus host disease (GvHD) after withdrawal of immunosuppression and/or DLI. GvHD and infections were the main contributors to a substantial transplant related morbidity and mortality, the major drawback of allogeneic stem cell transplantation. Therefore, clinical studies are necessary to further investigate and improve the selection of patients with metastatic RCC or other solid tumors for NST and to reduce post-transplant complications. This article reviews the results, side effects and potential future developments of NST in the treatment of solid tumors.

Abstract
BACKGROUND Allogeneic stem-cell transplantation (allo-SCT) can induce curative graft-versus-leukemia reactions for hematologic malignancies through allogeneic immunity. Because the gastrointestinal tract is a target of graft-versus-host disease (GvHD), colorectal cancer might be a candidate for allo-SCT. METHODS Four patients with metastatic colorectal cancer underwent reduced-intensity stem-cell transplantation (RIST) in the National Cancer Center Hospital between July 2002 and February 2003. Three patients received transplants from an human leukocyte antigen (HLA)-identical related donor, and the remaining patient received selected CD34-positive cells from a two-loci HLA-mismatched donor. The basis of preparative regimen was busulfan 4 mg/kg for 2 days and fludarabine 25 mg/kg for 6 days. RESULTS All the patients tolerated the preparative regimen and achieved engraftment without significant toxicities. All developed acute or chronic GvHD. Although serum levels of CA19-9 and carcinoembryonic antigen were transiently elevated after RIST in all the patients, the levels subsequently decreased below the levels from before RIST in all but one patient. Three had measurable lesions before RIST, one achieved partial response, and the others stable disease, which was durable for 120 and 60 days. Three patients died; the causes of death were progressive disease, GvHD, and accident. Postmortem examination was obtained for two patients; in one patient, the peritoneal metastatic lesions macroscopically disappeared, and in the other patient, the supraclavicular lymph node disappeared while the other measurable lesions remained stable. CONCLUSIONS All the patients showed some evidence suggesting the presence of a graft-versus-tumor effect for colorectal cancer, which should be confirmed in a future prospective trial.

Abstract
OBJECTIVE Experiments were designed to investigate a new concept aiming for induction of graft-vs-malignancy (GVM) effect prior to stem cell transplantation (SCT). Mismatched lymphocytes given pre-SCT will be followed by a selective elimination of alloreactive donor lymphocytes, thus avoiding lethal graft-vs-host disease (GVHD). METHODS Recipient mice treated with sublethal total-body irradiation (TBI) received a single injection of allogeneic splenocytes, either naïve or rIL-2 activated (ADL), for induction of GVHD. To prevent lethal GVHD, cyclophosphamide (Cy) (200 mg/kg) or TBI (9 Gy) were given 4 days after cell inoculation. One day later, treated mice were rescued with syngeneic bone marrow cells. RESULTS Both Cy and TBI significantly (p < 0.001) prevented GVHD in all recipients inoculated with either naïve cells or ADL and all recipients survived more than 250 days. Control mice not rescued with CY or TBI died of GVHD within 20 to 25 days. A significant proportion of recipients inoculated with 4T1 tumor cells, treated with ADL followed by TBI 9 Gy, survived more than 250 days disease-free in comparison with 22 days in untreated control mice (p <0.001). CONCLUSIONS Attempting to induce short, yet effective, GVM effects before rather than after SCT, thus avoiding lethal GVHD, may represent an innovative approach for more effective yet safer use of SCT for tumor immunotherapy.

Abstract
OBJECTIVE Graft-vs-host disease (GVHD) is a serious complication of allogeneic stem cell transplantation (SCT) and donor lymphocyte infusion (DLI), for which no effective therapy exists. In our study, KRN7000, a synthetic analog of alpha-galactosylceramide, known for its ability to activate natural killer T cells, was tested for its ability to prevent onset of GVHD in a murine model of haploidentical major histocompatible (MHC) mismatched hematopoietic cells. METHODS Irradiated (BALB/cXC57BL/6)F1 mice were inoculated with parental C57BL/6 splenocytes with or without SCT. KRN7000 was given intraperitoneally as single or multiple doses at 100 microg/kg/dose and mice were followed up for GVHD clinical symptoms and for survival. The effect of KRN7000 treatment was also tested in vitro for the induction of suppression of alloreactivity in mixed lymphocyte reaction (MLR). RESULTS KRN7000 prevented development of GVHD symptoms in almost all mice and 52/53 mice maintained a healthy profile for more than 235 days. Most vehicle-treated mice or untreated controls died of GVHD within a median of 3 weeks. KRN7000 treatment did not prevent engraftment of donor cells following sublethal total-body irradiation (TBI) and allowed durable persistence of donor cells following lethal TBI and SCT. Splenocytes derived from KRN7000-treated mice suppressed efficiently mixed lymphocyte reaction (MLR) in vitro. CONCLUSION GVHD induced by alloreactive lymphocytes can be prevented by KRN7000. GVHD prevention may be accomplished by regulation of T cell function and might thus provide a new modality for safer SCT and DLI.

Abstract
Despite major progress in treating hematologic malignancies and, to a lesser extent, metastatic solid tumors, much work remains ahead. With the anticancer potential of immunotherapy not yet fully exploited, patients with leukemia, malignant lymphoma, and other hematologic malignancies for which high-dose chemoradiotherapy is frequently recommended in conjunction with stem cell transplantation (SCT) can now benefit from the advantages of immunotherapy mediated by cytokines or alloreactive donor lymphocytes, while minimizing procedure-related toxicity and mortality. The feasibility of applying allogeneic cell-mediated immunotherapy in conjunction with allogeneic SCT following reduced-intensity conditioning, with minimal toxicity and no serious transplant-related complications, makes it possible to undertake such procedures on an outpatient basis as well as to offer an option for cure to elderly individuals and patients with less than optimal performance status. Being well tolerated, reduced-intensity transplants also offer a chance for cure to patients with otherwise resistant leukemia and malignant lymphoma who have relapsed after autologous SCT. Thus, the traditional obstacle of very high transplant-related toxicity and mortality due to multiorgan failure from cumulative toxicity of multiple anticancer agents and radiation therapy is overcome. Although immunotherapy mediated by allogeneic lymphocytes can be most effective, the immune potential of donor lymphocytes should be maximized by nonspecific or specific activation in vitro or in vivo, or both, for more effective eradication of resistant tumor cells, including in patients with bulky disease. More important is the challenge to target donor lymphocytes to the tumor and minimize their capacity to induce responses against normal host tissues, which frequently results in severe acute and chronic graft-versus-host disease (GVHD). Alternatively, donor lymphocytes should be eliminated as soon as tumor eradication is completed, or as soon as severe GVHD becomes prohibitive. Based on available experience, clinical application of innovative therapy, especially at the stage of minimal residual disease (MRD), may open new horizons for the treatment of malignancies considered until recently to be incurable. The feasibility of controlling cancer by targeted chemotherapy, best illustrated by the phenomenal activity of imatinib in patients with chronic myelogenous leukemia and, more recently, in gastrointestinal stromal tumors (including in patients fully resistant to all known anticancer agents) suggests that in the future, tumor-specific chemotherapy may represent the ultimate goal for achieving a stage of MRD with minimal multiorgan toxicity. Together, the combination of immunotherapy and targeted chemotherapy may provide the most logical approach for making real progress in controlling resistant hematologic malignancies and metastatic solid tumors.

Abstract
The effect of allogeneic versus syngeneic killer cells derived from normal or severe combined immunodeficiency disease (SCID) mice was evaluated for induction of antitumor reaction in a murine model of mammary carcinoma. Tumor cells of H-2d origin were injected intravenously into H-2(d/b) mice 24 hours after total body irradiation (4 Gy). On the following day, lymphokine-activated killer (LAK) splenocytes, derived from either minor (H-2d) or major (H-2b) histocompatibility complex (MHC)-mismatched parental normal mice or MHC (H-2b)-mismatched SCID mice, were given intravenously. LAK cells of H-2d normal or SCID mice, syngeneic to the tumor, were inoculated in parallel. The results show that LAK cells derived from minor histocompatibility complex-mismatched or MHC-mismatched parental normal mice improved the probability of tumor-free survival as compared with LAK cells syngeneic to the tumor cells, but they aggravated the severity of graft-versus-host disease. SCID splenocytes serving as a source of natural killer (NK) cells were expanded and activated in vitro by rIL-2 to obtain a sufficient number of DX5+ CD3- CD8- NK cells (SCID-LAK). H-2b SCID-LAK cells did not cause graft-versus-host disease and significantly delayed tumor growth compared with syngeneic H-2d SCID-LAK cells, as indicated by tumor colony assays in vitro and adoptive transfer experiments. However, the graft-versus-tumor effect was not long lasting, and treated mice finally died of tumor. Our results show an advantage of allogeneic over syngeneic cell therapy for achieving a graft-versus-tumor effect by rIL-2-activated T cells and NK cells. Periodic repetition of NK treatments may be required to achieve more durable antitumor effects.

Abstract
Nonmyeloblative stem cell transplantation (NST, SCT) aims to induce host-versus-graft tolerance for subsequent immunotherapy of underlying disease with alloreactive donor lymphocytes, focusing on well-tolerated conditioning suitable for elderly individuals or for other risk factors. However, there is a subset of high-risk patients who cannot tolerate NST. A new protocol consisting of fludarabine 30 mg/m(2) x 6 days (days -8 to -2), very-low-dose busulfan (2 mg/kg x 2 days, days -6 to -5), without anti thymocyte globulin (ATG), was employed in 11 high-risk patients aged 26-58 years. Graft-versus-host-disease (GVHD) prophylaxis consisted of low-dose and short-course cyclosporine-A (CSA) alone. One patient died during the nadir due to pulmonary complications. Other patients showed rapid three-lineage engraftment, without complete aplasia; 6/10 patients did not require platelet transfusion and 8/10 had full donor chimerism without transient mixed chimerism. Owing to intentional selection of highly poor-risk patients, overall mortality was high and only one patient survived. Acute GVHD (>/=grade I) occurred in 8/10 evaluable patients, 5/8 while off CSA; 5/8 developed grade III-IV acute GVHD. It appears that our modified, minimally ablative stem cell transplantation (MST) may be used for high-risk patients in need of allo-SCT. Furthermore, although the MST conditioning is not myeloablative, it results in myeloablation of the host hematopoietic system, mediated by alloreactive lymphocytes.

Abstract
Donor lymphocyte infusion mediates most effective graft- versus-leukemia (GVL) effects following induction of host-versus-graft tolerance by transplantation of donor stem cells. This study was designed to maximize GVL effects across both major (MHC) and minor (mHgs) histocompatibility barriers in recipients inoculated with murine B-cell leukemia (BCL1), using specifically immune donor lymphocytes. GVL effects were induced with donor spleen cells from mice immunized across MHC or mHgs barriers with BCL/1 cells or normal BALB/c spleen cells. Our data suggest that spleen cells from donor mice immunized against murine B-cell leukemia of BALB/c origin, or to a lesser extent against normal host alloantigens, induce better therapeutic GVL effects with less great-versus-host disease (GVHD) across both mHgs and MHC. The cytokine profile of effector cells inducing predominantly GVL effects with reduced GVHD across MHC and mHg barriers consisted preferentially of upregulated IFN-gamma, IL-2, IL-10 and IL-12 in donors, implying a Th-1 to Th-2 cytokine shift. We hypothesize that immunotherapy with immune donor lymphocytes sensitized in vivo or in vitro with allogeneic tumor cells or normal host cells together with allogeneic BMT may provide an effective approach for amplifying GVL effects, while reducing procedure-related morbidity and mortality due to uncontrolled GVHD.

Abstract
Several clinical observations have confirmed that a donor immune-mediated anti-malignancy effect, called graft-versus-leukemia or graft-versus-tumor, occurs following allogeneic hematopoietic stem cell transplantation. While the potential antitumor effect mediated by donor lymphocytes has been established in many hematological malignancies, its efficacy in inducing clinically meaningful responses in solid tumors has been largely unexplored despite evidence of its potential benefit in experimental animal models. Only in recent years has the investigational application of non-myeloablative stem cell transplantation in patients with refractory non-hematological cancers proved that a graft-versus-tumor effect can be generated in patients with metastatic renal cell cancer and possibly with other solid tumors. In the present article we review the biological basis, development and early clinical results of this novel immunotherapeutic approach for solid tumors.

Abstract
New approaches are needed for maximizing specific responses against tumor cells resistant to chemotherapy. While cytokine therapy may amplify natural resistance against minimal residual disease, more robust anti-leukemia reactivity can be provided by allogeneic bone marrow transplantation (BMT) in conjunction with myeloablative, hence hazardous, conditioning, at the cost of graft-versus-host disease (GVHD). Documentation of the capacity of donor lymphocyte infusion (DLI) given late post BMT, when patients were off immunosuppression, in early 1987, with successful reversal of relapse and cure of patients fully resistant to maximally tolerated doses of chemoradiotherapy, with many patients alive and well >10-15 years later, indicated two important facts. First, resistant tumors are unlikely to be cured with higher doses of chemoradiotherapy that may harm the patient but not eliminate all his clonogenic tumor cells. Second, that under condition of tolerance to donor alloantigens, DLI may provide a cure to otherwise resistant patients. These observations paved the road for clinical application of non-myeloablative stem cell transplantation (NST), in the early 90s, based on a two-step procedure, first involving induction of transplantation tolerance to donor alloantigens by engraftment of donor stem cells, following safe lymphoablative rather than myeloablative conditioning. Second, use of donor lymphocytes for elimination of residual tumor or otherwise abnormal hematopoietic cells by immune-mediated graft-versus-host effects inducible by mobilized blood stem cell allografts containing larger inocula of donor T cells, or supported by post-grafting DLI when patients were off immunosuppressive modalities.

Abstract
Previously, there was very little interest in investigating allogeneic hematopoietic stem cell transplantation (alloHSCT) in breast cancer because of the significant morbidity and mortality associated with this procedure, as well as the disappointing results observed in clinical trials with high-dose chemotherapy and autologous hematopoietic stem cell transplantation in advanced breast cancer. However, the development of nonmyeloablative (reduced-intensity) conditioning regimens, which have less treatment-related mortality but preserve the T cell-mediated graft-versus-tumor (GVT) effect, has led to the investigation of nonmyeloablative alloHSCT in diseases that had not previously been considered for conventional alloHSCT, including metastatic breast cancer. Laboratory data demonstrate that T cell-mediated responses to breast cancer that inhibit tumor growth are possible and provide the rationale to pursue allogeneic adoptive cellular therapy as a strategy to eliminate breast cancer. Early reports of nonmyeloablative alloHSCT indicate that a clinical GVT effect against breast cancer does exist. The responses appear to be dependent on the development of complete donor lymphoid chimerism, and responses may be delayed. The results from these initial trials must be interpreted cautiously. It is unlikely that nonmyeloablative alloHSCT by itself will result in complete eradication of metastatic breast cancer; however, it may serve as a therapeutic platform to enhance the effects of currently available immunotherapies (eg, trastuzumab administration) and complement existing cytotoxic therapies. Well-designed studies will be necessary to determine the clinical efficacy of nonmyeloablative alloHSCT as adoptive cellular therapy in metastatic breast cancer.

Abstract
A frequent outcome of allogeneic stem cell transplantation (alloSCT) in the treatment of leukemia is the destruction of the host hematolymphoid compartment and, thus, the malignancy, through the combined action of high-dose chemoradiotherapy and a T-cell-mediated graft-versus-host effect. Unfortunately, alloSCT is frequently limited by toxicity, including graft-versus-host disease (GVHD), and has not been successful in the treatment of tumors derived from solid organs. Here we report a novel cooperation between host and donor T cells in the response to a tumor cell vaccine given after a nonmyeloablative allogeneic stem cell transplantation (NST) protocol that achieves stable mixed bone marrow chimerism. Treatment of animals with NST, posttransplantation donor lymphocyte infusions (DLIs), and a vaccine, comprising irradiated autologous tumor cells mixed with a granulocyte-macrophage colony-stimulating factor (GM-CSF)-producing bystander line, results in potent and specific antitumor immunity. This combined modality immunotherapy, administered after surgical removal of the primary tumor, cured metastatic mammary cancer in most animals without inducing GVHD. Cured animals contained tumor-specific T cells of both host and donor origin, but immunodeficient hosts could not be cured by NST, DLI, and vaccine administration. Thus, transfer of allogeneic donor T cells may help break functional tolerance of a host immune system to a solid tumor, thereby providing a rationale for the generation of mixed hematopoietic chimerism by NST prior to tumor cell vaccination.

Abstract
Adoptive transfer of allogeneic T cells has unmatched efficacy to eradicate leukemic cells. We therefore sought to evaluate in kinetic terms interactions between T cells and allogeneic leukemic cells. T cells primed against the model B6(dom1) minor histocompatibility antigen were adoptively transferred in irradiated B10 (B6(dom1)-positive) and congenic B10.H7(b) (B6(dom1)-negative) recipients, some of which were also injected with EL4 leukemia/lymphoma cells (B6(dom1)-positive). A key finding was that the tissue distribution of the target epitope dramatically influenced the outcome of adoptive cancer immunotherapy. Widespread expression of B6(dom1) in B10 recipients induced apoptosis and dysfunction of antigen-specific T cells. Furthermore, in leukemic B10 and B10.H7(b) hosts, a massive accumulation of effector/memory B6(dom1)-specific T cells was detected in the bone marrow, the main site of EL4 cell growth. The accumulation of effector/memory cells in recipient bone marrow was EL4 dependent, and its kinetics was different from that observed in recipient spleen. We conclude that strategies must be devised to prevent apoptosis of adoptively transferred T cells confronted with a high antigen load and that local monitoring of the immune response at the site of tumor growth may be mandatory for a meaningful assessment of the efficacy of adoptive immunotherapy.

Abstract
It has been shown that after allogeneic peripheral blood stem cell transplantation (PBSCT), donor T cells can induce potent graft-versus-tumor (GVT) effects in hematologic malignancies and possibly solid tumors such as renal cell carcinoma. Two patients (27 and 30 years old) with metastatic melanoma received allogeneic PBSCT from an HLA-identical sibling donor after reduced conditioning with fludarabine, carmustine and melphalan. One patient showed a delayed mixed response with complete regression of lymph node metastases but persistent liver metastasis at day +60 and +120, consistent with a GVT response. In order to generate donor-derived tumor-reactive cytotoxic T lymphocytes (CTLs), peripheral blood mononuclear cells were stimulated with donor dendritic cells (DCs) loaded with host tumor lysate. Using these culture conditions, a marked increase in CD8(+) CTLs was observed in both donors exhibiting a strong MHC class I-restricted cytotoxic activity against the host tumor without cross-reactivity against nonmalignant host cells. CDR3 spectratyping was used to analyze the complexity of T-cell subpopulations in both CTL lines. Results demonstrate that oligoclonal T cells are expanded in vitro, exhibiting a marked overexpression of TCRVbeta3 (donor 1) and TCRVbeta4/Vbeta11 (donor 2) subfamilies. Functional (ELISPOT assay) and phenotypic (CDR3 spectratyping, sequencing Vbeta transcripts) analysis of patients' T cells at different time points after transplantation demonstrated an expansion of alloreactive T cells with a limited TCR Vbeta pattern. The Vbeta3 cDNA clone, being predominant in the CTL line from donor 1, could not be identified in patient 1 peripheral blood lymphocytes after transplant. Altogether, our results provide the first evidence that GVT effects against melanoma can induce tumor regression and that oligoclonal donor-derived CTLs specific against host tumor cells can be generated in vitro that may be used for adoptive T-cell transfer after allogeneic transplantation.

Abstract
Donor lymphocyte infusion (DLI), pioneered in Jerusalem in January 1987, represents the first proof of principle of the absolute efficacy of immunotherapy as a means of curing cancer. Immunotherapy with alloreactive donor lymphocytes can eliminate "the last tumor cell" even in patients with hematological malignancies resistant to maximally tolerated doses of chemoradiotherapy. Alloreactive lymphocytes that can mediate anti-tumor effects following induction of host-versus-graft tolerance induced by transplantation of donor stem cells, can induce graft-versus-malignancy (GVM) effects which are usually accompanied by graft-versus-host disease (GVHD). However, occasionally GVM effects may also be accomplished independently of clinically overt GVHD. Interestingly, allogeneic donor lymphocytes may also eliminate undesirable host-derived hematopoietic cells in a large number of nonmalignant indications including genetic diseases, diseases caused by deficiency of stem cell products, and autoimmune disorders mediated by self-reactive lymphocytes. The cumulative clinical experience suggests feasibility of effective induction of graft-versus-leukemia (GVL); graft-versus-lymphoma (GVLy); graft-versus-multiple myeloma, as well as graft-versus-solid tumors (GVT), well-documented in patients with renal and breast cancer, even in patients with resistant disease that have failed myeloablative chemoradiotherapy. These observations that suggested that cell therapy by donor lymphocytes is the main therapeutic benefit of bone marrow transplantation (BMT) led to development of the nonmyeloablative approach for safer allogeneic stem cell transplantation. Nonmyeloablative stem cell transplantation (NST) makes it possible to offer an option for cure to elderly patients with no upper age limit, as well as to patients with poor performance status not considered eligible for conventional BMT. Using well-tolerated NST regimen, allogeneic stem cell transplantation can be accomplished with minimal procedure-related toxicity and mortality, possibly even on an outpatient basis. Immunotherapy mediated by adoptive allogeneic cell-mediated immunotherapy can be further improved by utilizing specifically immune donor lymphocytes, thus maximizing their efficacy against undesirable target cells of host origin on the one hand, while minimizing their ontoward efficacy against normal cells of host origin that could result in GVHD on the other. Taken together, DLI and subsequently NST, may have opened new horizons for treatment of life-threatening malignant and nonmalignant disorders correctable by allogeneic stem cell transplantation. It is anticipated that further improvement of reactivity and specificity of donor lymphocytes will lead to safer clinical application of cell therapy for a larger number of indications toward improving disease-free survival in a large number of indications while minimizing immediate and late procedure-related complications.

Abstract
Allogeneic stem cell transplantation (SCT) is the treatment of choice for many hematological malignancies. Its curative graft-versus-leukemia (GvL) effect is mainly mediated by donor-derived alloreactive T cells. However, if the donor T cells are not selected for their reactivity against leukemic cells, the GvL effect is often associated with graft-versus-host disease (GvHD), a major complication of SCT. Here we summarize our current knowledge on leukemia-associated antigens and discuss strategies to apply minor and major histocompatibility antigens for cellular immunotherapy of hematological malignancies with a low risk of GvHD.
