Abstract
Immunotherapeutic ablation of lymphoma is a conceptually attractive treatment strategy that is the subject of intense translational research. Cytotoxic T lymphocytes (CTLs) that are genetically modified to express CD19- or CD20-specific, single-chain antibody-derived chimeric antigen receptors (CARs) display HLA-independent antigen-specific recognition/killing of lymphoma targets. Here, we describe our initial experience in applying CAR-redirected autologous CTL adoptive therapy to patients with recurrent lymphoma. Using plasmid vector electrotransfer/drug selection systems, cloned and polyclonal CAR(+) CTLs were generated from autologous peripheral blood mononuclear cells and expanded in vitro to cell numbers sufficient for clinical use. In 2 FDA-authorized trials, patients with recurrent diffuse large cell lymphoma were treated with cloned CD8(+) CTLs expressing a CD20-specific CAR (along with NeoR) after autologous hematopoietic stem cell transplantation, and patients with refractory follicular lymphoma were treated with polyclonal T cell preparations expressing a CD19-specific CAR (along with HyTK, a fusion of hygromycin resistance and HSV-1 thymidine kinase suicide genes) and low-dose s.c. recombinant human interleukin-2. A total of 15 infusions were administered (5 at 10(8)cells/m(2), 7 at 10(9)cells/m(2), and 3 at 2 x 10(9)cells/m(2)) to 4 patients. Overt toxicities attributable to CTL administration were not observed; however, detection of transferred CTLs in the circulation, as measured by quantitative polymerase chain reaction, was short (24 hours to 7 days), and cellular antitransgene immune rejection responses were noted in 2 patients. These studies reveal the primary barrier to therapeutic efficacy is limited persistence, and provide the rationale to prospectively define T cell populations intrinsically programmed for survival after adoptive transfer and to modulate the immune status of recipients to prevent/delay antitransgene rejection responses.

Abstract
This study describes the development of an human granulocyte-macrophage colony-stimulating factor DNA cationic-lipid complexed autologous tumour cell vaccine (hGM-CSF CLDC ATCV) and its implementation, following a chemotherapy treatment protocol, in a randomized, placebo-controlled, double-blinded clinical trial in pet dogs with naturally occurring lymphoma. We hypothesized that the use of this vaccine would result in an antitumour immune response leading to improved first remission duration and overall survival in dogs with B-cell lymphoma when compared with chemotherapy alone. Immune stimulation generated by hGM-CSF CLDC ATCV was assessed by means of surrogate in vivo analysis (delayed-type hypersensitivity [DTH]) as well as an ex vivo cellular assay (lymphocyte proliferation assay). The vaccine approach considered in the current report did not result in clinically improved outcomes. A small measure of immunomodulation was documented by DTH and several modifications to the approach are suggested. This report illustrates the feasibility of clinical trials with vaccine strategies using companion animals with non-Hodgkin's lymphoma.

Abstract
PURPOSE The growth of non-Hodgkin lymphomas can be influenced by tumor-immune system interactions. Cytotoxic T-lymphocyte antigen 4 (CTLA-4) is a negative regulator of T-cell activation that serves to dampen antitumor immune responses. Blocking anti-CTLA-4 monoclonal antibodies improves host resistance to immunogenic tumors, and the anti-CTLA-4 antibody ipilimumab (MDX-010) has clinical activity against melanoma, prostate, and ovarian cancers. EXPERIMENTAL DESIGN We did a phase I trial of ipilimumab in patients with relapsed/refractory B-cell lymphoma to evaluate safety, immunologic activity, and potential clinical efficacy. Treatment consisted of ipilimumab at 3 mg/kg and then monthly at 1 mg/kg x 3 months (dose level 1), with subsequent escalation to 3 mg/kg monthly x 4 months (dose level 2). RESULTS Eighteen patients were treated, 12 at the lower dose level and 6 at the higher dose level. Ipilimumab was generally well tolerated, with common adverse events attributed to it, including diarrhea, headache, abdominal pain, anorexia, fatigue, neutropenia, and thrombocytopenia. Two patients had clinical responses; one patient with diffuse large B-cell lymphoma had an ongoing complete response (>31 months), and one with follicular lymphoma had a partial response lasting 19 months. In 5 of 16 cases tested (31%), T-cell proliferation to recall antigens was significantly increased (>2-fold) after ipilimumab therapy. CONCLUSIONS Blockade of CTLA-4 signaling with the use of ipilimumab is well tolerated at the doses used and has antitumor activity in patients with B-cell lymphoma. Further evaluation of ipilimumab alone or in combination with other agents in B-cell lymphoma patients is therefore warranted.

Abstract
Lymphoma is a heterogeneous malignancy of the lymphatic system characterized by proliferation of lymphoid cells or their precursors. Non-Hodgkin lymphoma (NHL) is associated with significant morbidity and is the seventh leading cause of death in the United States. Manifestations of NHL as well as complications of the disease and its management are frequently encountered in the head and neck region and often require specific treatment and modifications in the provision of oral health care. The purpose of this article is to review current concepts of the pathophysiology, as well as medical and oral health care management of NHL.

Abstract
The collection of epitopes present within the variable regions of the tumor-specific clonal immunoglobulin expressed by B cell lymphomas (idiotype, Id) can serve as a target for active immunotherapy. Traditionally, tumor-derived Id protein is chemically conjugated to the immunogenic foreign carrier protein keyhole limpet hemocyanin (KLH) using glutaraldehyde to serve as a therapeutic vaccine. While this approach offered promising results for some patients treated in early clinical trials, glutaraldehyde Id-KLH vaccines have failed to induce immune and clinical responses in many vaccinated subjects. We recently described an alternative conjugation method employing maleimide-sulfhydryl chemistry that significantly increased the therapeutic efficacy of Id-KLH vaccines in three different murine B cell lymphoma models, with protection mediated by either CD8(+) T cells or antibodies. We now define in detail the methods and parameters critical for enhancing the in vivo immunogenicity of human as well as murine Id-KLH conjugate vaccines. Optimal conditions for Id sulfhydryl pre-reduction were determined, and maleimide Id-KLH conjugates maintained stability and potency even after prolonged storage. Field flow fractionation analysis of Id-KLH particle size revealed that maleimide conjugates were far more uniform in size than glutaraldehyde conjugates. Under increasingly stringent conditions, maleimide Id-KLH vaccines maintained superior efficacy over glutaraldehyde Id-KLH in treating established, disseminated murine lymphoma. More importantly, human maleimide Id-KLH conjugates were consistently superior to glutaraldehyde Id-KLH conjugates in inducing Id-specific antibody and T cell responses. The described methods should be easily adaptable to the production of clinical grade vaccines for human trials in B cell malignancies.

Abstract
Therapeutic vaccination of B cell lymphoma patients with tumor-specific Ig (idiotype, or Id) chemically coupled to the immunogenic foreign carrier protein keyhole limpet hemocyanin (KLH) using glutaraldehyde has shown promising results in early clinical trials, and phase III trials are underway. However, glutaraldehyde Id-KLH vaccines fail to elicit anti-Id immune and clinical responses in many patients, possibly because glutaraldehyde reacts with lysine, cysteine, tyrosine, and histidine residues, damaging critical immunogenic epitopes. A sulfhydryl-based tumor Ag-carrier protein conjugation system using maleimide chemistry was used to enhance the efficacy of Id-KLH vaccines. Maleimide Id-KLH conjugates eradicated A20 lymphoma from most tumor-bearing mice, whereas glutaraldehyde Id-KLH had little efficacy. Maleimide Id-KLH elicited tumor-specific IgG Abs and T cells, with CD8(+) T cells being the major effectors of antilymphoma immunity. Maleimide Id-KLH vaccines also demonstrated superior efficacy in 38C13 and BCL-1 lymphoma models, where Abs were shown to be critical for protection. Importantly, standard glutaraldehyde Id-KLH conjugation procedures could result in "overconjugation" of the tumor Ag, leading to decreased efficacy, whereas the heterobifunctional maleimide-based conjugation yielded potent vaccine product regardless of conjugation duration. Under lysosomal processing conditions, the Id-carrier protein linkage was cleavable only after maleimide conjugation. Maleimide KLH conjugation was easily performed with human Igs analogous to those used in Id-KLH clinical trials. These data support the evaluation of sulfhydryl-based Id-KLH vaccines in lymphoma clinical trials and possibly the use of tumor Ag-carrier protein vaccines for other cancers.

Abstract
Therapeutic cancer vaccines target the cellular arm of the immune system to initiate a cytotoxic T-lymphocyte response against tumor-associated antigens. Immunotherapy offers one of the few therapeutic options that reproducibly leads to a subset of patients with long-term remissions (seemingly cures) of widely metastatic disease. Therapeutic cancer vaccines tested in clinical trials have included inactivated tumor cells administered in immunological adjuvants or after genetic modification to increase their immunogenicity. Other forms are heat shock protein vaccines and anti-ganglioside antibodies. Tumor-associated antigenic peptides have been fully characterized for some cancers. Finally, strategies to directly expand antitumor T lymphocytes and adoptively transfer them to patients with cancer have been developed and shown to induce objective tumor regressions.

Abstract
The in vitro priming of tumor-specific T cells by dendritic cells (DCs) phagocytosing killed tumor cells can be augmented in the presence of antitumor monoclonal antibody (mAb). We investigated whether DCs phagocytosing killed lymphoma cells coated with tumor-specific antibody could elicit antitumor immunity in vivo. Irradiated murine 38C13 lymphoma cells were cocultured with bone marrow-derived DCs in the presence or absence of tumor-specific mAb. Mice vaccinated with DCs cocultured with mAb-coated tumor cells were protected from tumor challenge (60% long-term survival), whereas DCs loaded with tumor cells alone were much less effective. The opsonized whole tumor cell-DC vaccine elicited significantly better tumor protection than a traditional lymphoma idiotype (Id) protein vaccine, and in combination with chemotherapy could eradicate preexisting tumor. Moreover, the DC vaccine protected animals from both wild-type and Id-negative variant tumor cells, indicating that Id is not a major target of the induced tumor immunity. Protection was critically dependent upon CD8(+) T cells, with lesser contribution by CD4(+) T cells. Importantly, opsonized whole tumor cell-DC vaccination did not result in tissue-specific autoimmunity. Since opsonized whole tumor cell-DC and Id vaccines appear to target distinct tumor antigens, optimal antilymphoma immunity might be achieved by combining these approaches.

Abstract
Immunotherapy for cancer refers to a wide array of novel therapeutic interventions that harness the immune system to target and eradicate malignant cells in the host. Advances in the understanding of how tumor cells evade host immune detection, coupled with improved gene transduction technologies, have enabled investigators to propose and test novel immune-based therapies for B-cell malignancies. As a result, more immunogenic vaccination strategies, able to elicit immune responses to otherwise poorly immunogenic tumor antigens, are being tested in early clinical trials. Furthermore, with the development of efficient T-cell transduction methodologies, investigators are able to generate autologous antitumor T-cell responses through the introduction of chimeric antigen receptors able to target tumor antigens. However, whether the promising preclinical and phase I clinical data presented here will ultimately translate into improved survival of patients with B-cell malignancies remains largely unknown.

Abstract
Despite its potency, the wider use of immunotherapy for B cell malignancies is hampered by the lack of well-defined tumor-specific Ags. In this study, we demonstrate that an evolutionarily conserved 37-kDa immature laminin receptor protein (OFA-iLRP), a nonimmunogenic embryonic Ag expressed by a variety of tumors, is rendered immunogenic if targeted to the APCs using the CCR6 ligands MIP3alpha/CCL20 and mDF2beta. The CCR6 targeting facilitated efficient Ag cross-presentation and induction of tumor-neutralizing CTLs. Although the Ag targeting alone, without activation of dendritic cells (DCs), is proposed to induce tolerance, and MIP3alpha does not directly activate DCs, the MIP3alpha-based vaccine efficiently induced protective and therapeutic antitumor responses. The responses were as strong as those elicited by the OFA-iLRP fusions with moieties that activated DCs and Th1-type cytokine responses, mDF2beta, or mycobacterial Hsp70 Ag. Although the same cDNA encodes the dimerized high-affinity mature 67-kDa mLRP that is expressed in normal tissues to stabilize the binding of laminin to cell surface integrins, the vaccines expressing OFA-iLRP elicited long-term protective CD8(+) T cell-mediated memory responses against syngeneic B cell lymphoma, indicating the potential application of these simple vaccines as preventive and therapeutic formulations for human use.

Abstract
Follicular non-Hodgkin lymphoma (NHL) is an indolent, or slow-growing, malignant disease of the lymphoid tissue, which usually responds to initial therapy. However, the disease is characterized by multiple relapses and remissions, eventually causing death. Several effective therapies are available, but improvement of overall survival in patients with follicular NHL has not been demonstrated. Stimulation of the immune system to recognize malignant lymphoma cells as foreign has been demonstrated as a viable treatment option for patients with follicular NHL. Patient-specific vaccine therapy is a new form of active immunotherapy being studied for NHL. Clinical trials have shown a benefit for patients receiving this type of therapy. This article will provide a foundation for nurses caring for patients receiving patient-specific vaccine therapy.

Abstract
PURPOSE OF REVIEW Therapeutic vaccines targeting B cell lymphoma idiotype have reached an advanced stage of clinical development, with three multicenter randomized clinical trials ongoing. This review describes the rationale and development of this immunotherapeutic approach, the design of current phase III trials, and other active vaccination approaches likely to move forward into clinical testing for lymphomas. RECENT FINDINGS Several groups have achieved promising results in phase II trials of patient-specific idiotype vaccines, with very few side effects noted. Anti-idiotype antibodies, in addition to cytotoxic T cells, are now believed to be important effectors of antitumor immunity after idiotype vaccination. The manufacturing of autologous tumor idiotype proteins is being rapidly refined by the use of molecular technologies. Two trials involving more than 1000 patients are now under way, which use idiotype vaccination after induction chemotherapy; one trial completed accrual in early 2004. A third trial opened in 2004, using rituximab followed by idiotype vaccine with maintenance booster vaccines continuing throughout the period of normal B cell recovery. In accordance with the United States Food and Drug Administration, progression-free survival serves as the accepted primary efficacy endpoint in these studies. SUMMARY Lymphoma idiotype vaccination represents a promising immunotherapeutic approach targeting a patient-specific tumor antigen. The results of pivotal phase III trials for three first-generation idiotype vaccines will become available in the next several years. Advanced manufacturing techniques should permit application of this tailor-made treatment to large numbers of non-Hodgkin's lymphoma patients.

Abstract
The human CXC chemokine, stromal cell-derived factor 1 (SDF-1alpha), is known to function in vitro as a chemotactic factor for lymphocytes, monocytes, and dendritic cells. In the context that dendritic cells are powerful antigen-presenting cells, we hypothesized that adenoviral gene transfer of SDF-1alpha to tumors might inhibit growth of preexisting tumors through attracting dendritic cells to the tumor. AdSDF-1alpha mediated the expression of SDF-1alpha mRNA and protein in A549 cells in vitro, and the supernatant of the AdSDF-1alpha-infected A549 cells showed chemotactic activity for dendritic cells. When syngeneic murine CT26 colon carcinoma tumors (BALB/c) and B16 melanoma and Lewis lung cell carcinoma (C57Bl/6) were injected with AdSDF-1alpha (5 x 10(8) plaque-forming units), there was an accumulation of dendritic cells and CD8(+) cells within the tumor and significant inhibition of tumor growth compared with tumors injected with PBS or AdNull (control vector). The injection of AdSDF-1alpha into tumors induced the inflammatory enlargement and the accumulation of dendritic cells in the draining lymph node. Intratumoral AdSDF-1alpha administration elicited tumor-specific CTLs and adoptive transfer of splenocytes from AdSDF-1alpha-treated mice resulted in the elongation of survival after tumor challenge. Interestingly, in wild-type and CD4(-/-) mice but not in CD8(-/-) mice, AdSDF-1alpha inhibited the growth of the tumor. These observations suggest that adenoviral gene transfer of SDF-1alpha may be a useful strategy to accumulate dendritic cells in tumors and evoke antitumor immune responses to inhibit tumor growth.

Abstract
The efficacy of immunotherapeutic strategies for the treatment of lymphoid malignancies has been demonstrated in recent years. In patients with B-cell lymphomas, particularly indolent lymphoma, the use of passive immunotherapy, such as the anti-CD20 monoclonal antibody rituximab, has made an impressive impact on patient outcome. Personalized immunotherapy, a method that triggers the immune system to mount a response against tumor cells, has shown promising results in early clinical trials in hematologic malignancies. This therapeutic modality appears safe, with the most common adverse events being transient, local reactions at the site of injection. Furthermore, personalized immunotherapy has the potential to generate immunologic memory, which could provide prolonged remission. Currently, 3 large phase III studies are evaluating the efficacy and safety of personalized immunotherapy in patients with follicular lymphoma. It is hoped that the results of these studies will lead to the incorporation of this promising approach into the standard treatment of patients with lymphoma.

Abstract
Advances in cellular and molecular immunology have led to the development of strategies for effective augmentation of antitumour immune responses in cancer patients. This review focuses on the manipulation of T cell immunity either by active specific immunotherapy (ASI) using tumour vaccines, or by adoptive immunotherapy (ADI) with immune T cells. Such therapies offer exquisite specificity of tumour recognition based on the ability of the T cell to distinguish single amino acid differences in any protein from any compartment of the tumour cell. Examples are presented of clinical survival benefits for cancer patients by postoperative ASI with a modified autologous tumour vaccine of high quality. Furthermore, clinical studies employing ADI with T cells activated and expanded ex vivo have demonstrated 'proof of principle' that tumour-specific T cells are capable of mediating anticancer activity in vivo, as measured by regression of metastatic tumours. Translation of these findings into a standardised immunotherapy is, however, not easy and will require coordination and cooperation among academic, private and federal sectors.

Abstract
Idiotypic (Id) vaccination has shown promising results in patients with follicular lymphoma (FL). However, it still remains unclear whether the same approach might be suitable for the treatment of other B-cell malignancies. For this reason, we recently performed an interim analysis of patients proposed to receive this treatment at our center. The feasibility of employing idiotype vaccines was evaluated for five different B-cell malignancies in their first relapse, both in terms of induction and fusion, as well as overall treatment. Our data suggest that, unlike follicular lymphoma (87%), this approach is not feasible to treat other B-cell malignancies (0-20%) such as mantle cell, small lymphocytic, diffuse large cell and Burkitt's lymphoma (P < 0.01). The main difficulties encountered were technical problems related to the survival of idiotype-producing hybridomas (83%) and the early loss of idiotype production by growing hybridomas (17%). However, it remains possible that an idiotype vaccine might still be produced through molecular means for most, if not all cases of relapsing B-cell malignancies.

Abstract
Non-Hodgkin lymphoma (NHL) causes many deaths worldwide, and its incidence is increasing. Although some cases are associated with immunodeficiency, autoimmunity, or viral infections, in most cases the causes of NHL are not understood. However, there have been some important advances in our understanding of the development of healthy lymphocytes and the pathogenesis of NHL over the past 10 years. These advances have been accompanied by an improvement in treatment for NHL. Before the late 1990s, the only treatment option available was cytotoxic chemotherapy. In the past 10 years, however, high-dose chemotherapy and autologous stem-cell reconstitution have become established parts of treatment for aggressive lymphoma. Furthermore, monoclonal antibodies have become another therapeutic option. Rituximab (an anti-CD20 monoclonal antibody) is the most advanced monoclonal antibody in clinical trials and has become part of standard treatment for some lymphomas. Rituximab, and many other monoclonal antibodies, continue to be assessed in clinical studies. Monoclonal antibodies can be used alone or in combination with standard-dose or high-dose chemotherapy, and they can also be conjugated to radionuclides to enhance cytotoxicity. Here, we review advances in the treatment of NHL that have occurred over the past 10 years.

Abstract
Therapeutic cancer vaccines treat disease by stimulating the body's immune system. They are a form of active immunotherapy with the goal of producing an immune response that involves the cellular and humoral components of the immune system. These two components appear to be complementary and work together to induce tumor regression and long-lasting immunity to the disease being treated. This article reviews the history of cancer vaccine development, autologous and allogeneic vaccines, vaccine targets, carrier proteins, adjuvants, and clinical trial data of studies evaluating cancer vaccines. Knowledge of this emerging cancer treatment option will enable oncology nurses to be informed about cancer vaccines and accurately provide information about them to patients.
