Abstract
Background: Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma. Objectives: This study was conducted to evaluate efficacy and safety of interferon (IFN) α-2a combined with phototherapy for early-stage MF. Methods: Thirteen patients with early-stage MF received subcutaneous injections of IFN α-2a at 3 million IU combined with phototherapy three times per week for 6 months. Treatment efficacy was measured by changes in body surface area (BSA) score and modified severity-weighted assessment tool (mSWAT) score at 1, 3, and 6 months after treatment. Histopathologic examinations of skin lesions were performed before and after treatment. Results: After 3 months of treatment, all 13 patients achieved a partial response, and BSA and mSWAT scores were significantly lower than those at baseline (p < 0.001). After 6 months, BSA and mSWAT scores were significantly lower than those at baseline (p < 0.001) and after 3 months (p < 0.05). Eleven patients achieved complete remission and two patients achieved a partial response (overall response rate, 100%). Histopathologic examination showed a significant decrease in the number of atypical lymphocytes in both epidermis and dermis. No severe adverse effects occurred. Conclusion: IFN α-2a in combination with phototherapy may be an effective and safe alternative modality for early-stage MF.

Abstract
BACKGROUND In advanced stages, Cutaneous T-cell lymphomas (CTCL) can metastasize to extracutaneous regions. CTCL with metastasis exhibits unique clinicopathologic characteristics. PATIENTS AND METHODS This study collected 35 cases of primary CTCL with extracutaneous metastasis from a single institution over a period of 20 years. Clinicopathologic features including demographics, CD30 expression, large cell transformation, metastatic sites, T-cell receptor clonality studies and survival data were analyzed. RESULTS The study identified various CTCL entities including mycosis fungoides (MF), Sezary syndrome (SS), cutaneous anaplastic large cell lymphoma (C-ALCL), and primary cutaneous peripheral T-cell lymphoma, not otherwise specified (pcPTCL-NOS). Limited data showed that metastasis can be independent of large cell transformation and/or CD30 expression. Lymph nodes were the most common site of metastasis, followed by the bone marrow. Oropharyngeal metastasis is likely to accompany visceral organ or brain metastasis (P = .049). MF had a longer interval to metastasis than SS (P = .038). Patients with lymph node only metastasis have better survival than patients with metastasis to other sites (P = .012). CONCLUSION To the best of our knowledge, there are limited studies analyzing the clinicopathologic features of different CTCL entities with metastasis as a single population. This research provides valuable insights into the unique characteristics of metastatic CTCL.

Abstract
Cutaneous T cell lymphomas (CTCLs) are a heterogeneous group of lymphoproliferative neoplasms that exhibit a wide spectrum of immune-phenotypical, clinical, and histopathological features. The biology of CTCL is complex and remains elusive. In recent years, the application of next-generation sequencing (NGS) has evolved our understanding of the pathogenetic mechanisms, including genetic aberrations and epigenetic abnormalities that shape the mutational landscape of CTCL and represent one of the important pro-tumorigenic principles in CTCL initiation and progression. Still, identification of the major pathophysiological pathways including genetic and epigenetic components that mediate malignant clonal T cell expansion has not been achieved. This is of prime importance given the role of malignant T cell clones in fostering T helper 2 (Th2)-bias tumor microenvironment and fueling progressive immune dysregulation and tumor cell growth in CTCL patients, manifested by the secretion of Th2-associated cytokines and chemokines. Alterations in malignant cytokine and chemokine expression patterns orchestrate the inflammatory milieu and influence the migration dynamics of malignant clonal T cells. Here, we highlight recent insights about the molecular mechanisms of CTCL pathogenesis, emphasizing the role of cytokines, chemokines, and associated downstream signaling networks in driving immune defects, malignant transformation, and disease progression. In-depth characterization of the CTCL immunophenotype and tumoral microenvironment offers a facile opportunity to expand the therapeutic armamentarium of CTCL, an intractable malignant skin disease with poor prognosis and in dire need of curative treatment approaches.

Abstract
In the past few decades, immunotherapy has emerged as an effective therapeutic option for patients with cutaneous T cell lymphoma (CTCL). CTCL is characterized by progressive impairment of multiple arms of the immune system. Immunotherapy targets these deficits to stimulate a more robust antitumor response, thereby both clearing the malignant T cells and repairing the immune dysfunction. By potentiating rather than suppressing the immune system, immunotherapy can result in longer treatment responses than alternatives such as chemotherapy. In recent years, advances in our understanding of the pathogenesis of CTCL have led to the development of several new agents with promising efficacy profiles. The second article in this continuing medical education series describes the current immunotherapeutic options for treatment of CTCL, with a focus on how they interact with the immune system and their treatment outcomes in case studies and clinical trials. We will discuss established CTCL immunotherapies, such as interferons, photopheresis, and retinoids; emerging therapies, such as interleukin-12 and Toll-like receptor agonists; and new approaches to targeting tumor antigens and checkpoint molecules, such as mogamulizumab, anti-programmed cell death protein 1, anti-CD47, and chimeric antigen receptor T cell therapy. We also describe the principles of multimodality immunotherapy and the use of total skin electron beam therapy in such regimens.

Abstract
Cutaneous T-cell lymphoma (CTCL) is a heterogeneous disease group of unknown etiology with a complex immunological background. As CTCL arises from T cells that have a vital role in the antitumor response, their therapy is largely aimed at reversing the immunological mechanisms leading to or manifesting during this malignancy. Early disease stages can be controlled with skin-directed therapy in most CTCL cases. Still, advanced CTCL has a dismal prognosis and warrants systemic therapy. Despite considerable progress in understanding the pathophysiology of the disease and the numerous systemic treatment options available, long-term remission rates with conventional treatments alone are still low. Allogeneic hematopoietic stem cell transplantation is currently the only curative option for advanced CTCL, including mycosis fungoides and Sézary syndrome. The aims of this review is to summarize the recent findings on the immunology of this heterogeneous disease and to present the advances in its clinical management.

Abstract
We have investigated the HECA-452 expression in large plaque parapsoriasis (PP) and mycosis fungoides (MF) patients, evaluating the potential role of this biomarker in both cutaneous disorders. Skin specimens from 72 PP and 61 MF patients were selected in this study. We compared their actual histological diagnosis with their previous diagnosis and we found that all 72 PP patients had the same diagnosis as before (stable PP), while 26 out of 61 MF have a previous PP histological diagnosis (evolving PP). Our results show an increased expression of HECA-452 in MF compared to PP (p<0.01). Furthermore, evolving PP showed a significantly higher level of HECA-452 than stable PP (p< 0.05). We conclude that HECA-452 expression increases during the natural history of Mycosis Fungoides. HECA-452 could be used as a biomarker for MF and predict which PP evolves to MF.

Abstract
Sézary syndrome (SS) carries a poor prognosis, and infections represent the most frequent cause of death in SS patients. Toll-like receptors (TLRs) are a family of innate immune receptors that induce protective immune responses against infections. We sought to evaluate the ability of TLR agonists to induce inflammatory cytokine, Th2 cytokine, and type I interferon (IFN-I) production by peripheral blood mononuclear cells (PBMC) of untreated SS patients. We detected impaired IL-6, IL-10 and IL-13 secretion by PBMC induced by the agonists for TLR5, TLR3, TLR7 and TLR9 in SS patients, while it was partially recovered by TLR2/TLR4 and TLR7/8 agonists TNF secretion was restored following stimulation with TLR2/TLR4 agonists. IFN-γ was scarcely produced upon TLR activation in SS cells, albeit TLR 7/8 (CL097) enhanced their secretion at lower levels than the control group. TLR9 agonist efficiently induced IFN-I in SS patients, although this positive regulation was not observed for other cytokines, in direct contrast to the broad activity of CL097. Among the TLR agonists, TLR4 was able to induce pro-inflammatory, IL-10 and Th2 secretion, while TLR7-8 agonist induced the inflammatory cytokines, IFN-I and IFN-γ. These findings reveal a dysfunctional cytokine response upon both extracellular and intracellular TLR activation in SS patients, which was partially restored by TLRs agonists.

Abstract
Sézary syndrome (SS), an aggressive and leukemic form of cutaneous T-cell lymphoma, usually results in shortened survival. Improving innate immunity in SS by targeting natural killer (NK) cells with Toll-like receptor (TLR) agonists could be an interesting modulatory strategy. We evaluated the NK cell populations in SS patients assessing activating and inhibitory receptors expression and profiled the differential expression of TLR signaling pathway genes in unstimulated NK cells and after TLR7/8 stimulation. We observed preserved CD56bright NK cells and a low percentage of CD56dim NK cells in the peripheral blood of SS patients compared to those in the healthy control group. Both NK cell populations showed down-modulation of NKG2C and NKG2D expression, which was associated with high serum levels of the soluble form of NKG2D ligands. In contrast, an expansion of “memory” CD57+ NKG2C+ NK cells and high cytomegalovirus antibody titers were detected in SS patients. Profiling of the TLR signaling genes in NK cells from SS patients showed an abundance of differentially expressed genes (DEGs) in NK cells in the unstimulated condition, with mostly up-regulation of NFκB/JNK p38 pathway genes, but there was down-regulation of type I (IFN-α/β) and II (IFN-γ) interferon and IL-12A. After activation of NK cells with TLR7/8 agonist, the down-regulated genes correlated with the IFN response, and IL-12 became up-regulated, together with other antitumor factors. NK cell activation with a dual agonist for TLR7 and TLR8 is able to induce the expression of IFN-γ and type I IFN, which can improve immunity in SS patients.

Abstract
Interferons are polypeptides that naturally occur in the human body as a part of the innate immune response. By harnessing these immunomodulatory functions, synthetic interferons have shown efficacy in combating various diseases including cutaneous T-cell lymphoma. This article closely examines the qualities of interferon alfa and interferon gamma and the evidence behind their use in the 2 most common types of cutaneous T-cell lymphomas, namely, mycosis fungoides and Sézary syndrome.

Abstract
INTRODUCTION Cutaneous T-cell lymphomas (CTCLs) represent a group of extranodal non-Hodgkin lymphomas, of which mycosis fungoides (MF) is the most frequent. Standard therapeutic approaches are well established and often achieve stable disease. However, cure for MF is rare and thus novel therapies are needed. AREAS COVERED This review provides a discussion of the most promising new therapeutic approaches in the management of MF and other rare CTCLs. It includes targeted therapies with antibodies against surface molecules on malignant T cells (e.g., brentuximab), novel chemotherapeutic agents (e.g., pralatrexate), small-molecule compounds (e.g., panobinostat) and evidence of emerging targets in CTCLs (e.g., anti-IL-31). It also provides discussion of immune checkpoint inhibitors such as anti-PD1 that are worth considering in the treatment of leukaemic CTCL variants. Finally, it gives a brief overview of the possible use of stem-cell transplantation. EXPERT OPINION There is no doubt that progress has been made in the treatment of CTCLs with new, innovative and promising therapies approaching. However, there is still an urgent need to identify and test additional targets in well-designed clinical trials.

Abstract
PURPOSE In leukemic cutaneous T-cell lymphoma (L-CTCL), malignant T cells accumulate in the blood and give rise to widespread skin inflammation. Patients have intense pruritus, increased immunoglobulin E (IgE), and decreased T-helper (TH)-1 responses, and most die from infection. Depleting malignant T cells while preserving normal immunity is a clinical challenge. L-CTCL has been variably described as a malignancy of regulatory, TH2 and TH17 cells. EXPERIMENTAL DESIGN We analyzed phenotype and cytokine production in malignant and benign L-CTCL T cells, characterized the effects of malignant T cells on healthy T cells, and studied the immunomodulatory effects of treatment modalities in patients with L-CTCL. RESULTS Twelve out of 12 patients with L-CTCL overproduced TH2 cytokines. Remaining benign T cells were also strongly TH2 biased, suggesting a global TH2 skewing of the T-cell repertoire. Culture of benign T cells away from the malignant clone reduced TH2 and enhanced TH1 responses, but separate culture had no effect on malignant T cells. Coculture of healthy T cells with L-CTCL T cells reduced IFNγ production and neutralizing antibodies to interleukin (IL)-4 and IL-13 restored TH1 responses. In patients, enhanced TH1 responses were observed following a variety of treatment modalities that reduced malignant T-cell burden. CONCLUSIONS A global TH2 bias exists in both benign and malignant T cells in L-CTCL and may underlie the infectious susceptibility of patients. TH2 cytokines from malignant cells strongly inhibited TH1 responses. Our results suggest that therapies that inhibit TH2 cytokine activity, by virtue of their ability to improve TH1 responses, may have the potential to enhance both anticancer and antipathogen responses.

Abstract
Cutaneous T cell lymphoma (CTCL) is a cancer of skin-homing T cells with variants that include leukemic CTCL (L-CTCL), a malignancy of central memory T cells (T(CM)), and mycosis fungoides (MF), a malignancy of skin resident effector memory T cells (T(EM)). We report that low-dose alemtuzumab (αCD52) effectively treated patients with refractory L-CTCL but not MF. Alemtuzumab depleted all T cells in blood and depleted both benign and malignant T(CM) from skin, but a diverse population of skin resident T(EM) remained in skin after therapy. T cell depletion with alemtuzumab required the presence of neutrophils, a cell type frequent in blood but rare in normal skin. These data suggest that T(CM) were depleted because they recirculate between the blood and the skin, whereas skin resident T(EM) were spared because they are sessile and non-recirculating. After alemtuzumab treatment, skin T cells produced lower amounts of interleukin-4 and higher amounts of interferon-γ. Moreover, there was a marked lack of infections in alemtuzumab-treated L-CTCL patients despite the complete absence of T cells in the blood, suggesting that skin resident T(EM) can protect the skin from pathogens even in the absence of T cell recruitment from the circulation. Together, these data suggest that alemtuzumab may treat refractory L-CTCL without severely compromising the immune response to infection by depleting circulating T(CM) but sparing the skin resident T(EM) that provide local immune protection of the skin.

Abstract
In the management of patients with cutaneous T-cell lymphoma (CTCL), there are numerous distinct therapy options. Each of these therapies is discussed in terms of when to use it, what factors limit the success of the treatment, and what to expect. A menu is defined as a list of items from which to choose. The treatments for CTCL are presented in various menus where they are options for a particular goal in a particular setting of CTCL. The best recognized clinical scenarios of CTCL are those recognized by the staging system: limited patch plaque (T1), disseminated patch plaque (T2), erythroderma (T4), and tumor (T3). Each phase of the disease will have the menu of therapy options presented for a given goal of management.

Abstract
BACKGROUND Mycosis fungoides and Sézary syndrome are a class of lymphomas of skin-trafficking T cells, and they are the most common forms of cutaneous T-cell lymphoma (CTCL). Mycosis fungoides and Sézary syndrome are chronic, frequently incurable diseases with limited therapeutic options. PF-3512676 (formerly CPG 7909) is a Toll-like receptor 9 agonist that is being investigated for treatment of patients with advanced cancer. OBJECTIVE This study was conducted to determine the safety and tolerability of single-agent PF-3512676 in patients with CTCL. METHODS In this phase I dose-escalation study, patients (N = 28) with treatment-refractory, stage IB to IVA CTCL were enrolled in 6 sequential cohorts and treated with PF-3512676 (0.08, 0.16, 0.24, 0.28, 0.32, or 0.36 mg/kg) administered as 24 weekly subcutaneous injections. Primary end points were safety and tolerability. RESULTS Common adverse events (fatigue, rigors, injection-site reactions, myalgia, lymphopenia, leukopenia, neutropenia, and pyrexia) were mostly grade 1 or 2, and no patient developed specific symptoms associated with autoimmune disease. Clinical response rate to PF-3512676, as determined by both Composite Assessment of Index Lesion Severity and Physician Global Assessment, was 32% (3 complete clinical responses, 6 partial responses); the majority of responses (7/9; 78%) were ongoing at the end of study. LIMITATIONS This trial was not designed to rigorously assess efficacy. CONCLUSION Single-agent PF-3512676 was well tolerated and demonstrated antitumor activity in patients with refractory CTCL.

Abstract
An 8-year-old, mixed-breed dog with preputial epitheliotropic lymphoma was initially treated with cyclophosphamide, vincristine, and prednisolone. A short-term partial response was followed by disease progression after 4 weeks. Recombinant human interferon alpha-2a was administered starting at week 7. The interferon therapy resulted in rapid resolution of clinical signs and a 10-week disease-free interval. The lymphoma recurred at 17 weeks and did not respond to rescue chemotherapy. Additional oral lesions were treated with localized radiotherapy followed by increased dosages of interferon. This additional interferon treatment resulted in another 12 weeks of stable disease.

Abstract
Inflammation and cancer metastasis are associated with extravasation of leukocytes or tumor cells from blood into tissue. Such movement is believed to follow a coordinated and sequential molecular cascade initiated, in part, by the three members of the selectin family of carbohydrate-binding proteins: E-selectin (CD62E), L-selectin (CD62L) and P-selectin (CD62P). E-selectin is particularly noteworthy in disease by virtue of its expression on activated endothelium and on bone-skin microvascular linings and for its role in cell rolling, cell signaling and chemotaxis. E-selectin, along with L- or P-selectin, mediates cell tethering and rolling interactions through the recognition of sialo-fucosylated Lewis carbohydrates expressed on structurally diverse protein-lipid ligands on circulating leukocytes or tumor cells. Major advances in understanding the role of E-selectin in inflammation and cancer have been advanced by experiments assaying E-selectin-mediated rolling of leukocytes and tumor cells under hydrodynamic shear flow, by clinical models of E-selectin-dependent inflammation, by mice deficient in E-selectin and by mice deficient in glycosyltransferases that regulate the binding activity of E-selectin ligands. Here, the authors elaborate on how E-selectin and its ligands may facilitate leukocyte or tumor cell recruitment in inflammatory and metastatic settings. Antagonists that target cellular interactions with E-selectin and other members of the selectin family, including neutralizing monoclonal antibodies, competitive ligand inhibitors or metabolic carbohydrate mimetics, exemplify a growing arsenal of potentially effective therapeutics in controlling inflammation and the metastatic behavior of cancer.

Abstract
IL-21, a common gamma-chain cytokine secreted by activated CD4+ T cells, influences both humoral and cell-mediated immune responses through the regulation of T, B, dendritic, and natural killer (NK) cells. Sézary syndrome is an advanced form of cutaneous T-cell lymphoma, a clonally derived malignancy of CD4+ T cells that is characterized by profound defects in host cellular immune function. As a modulator of both innate and adaptive immune responses, IL-21 could play an important role in augmenting cell-mediated immunity in these patients. Normal donor and Sézary syndrome patient peripheral blood mononuclear cells were cultured with IL-21 and tested for CD8+ T- and NK-cell activation, NK-cell cytotoxicity, and tumor cell proliferation and apoptosis. IL-21 resulted in a modest increase in CD8+ T- and NK-cell activation, associated with a marked increase in cytolytic activity against both K562 and malignant CD4+ T-cell targets. Although IL-21 failed to demonstrate pro-apoptotic effects on the malignant CD4+ T cells, it is noteworthy that it had no demonstrable proliferative effects on these cells. Thus, IL-21 may play an important role in enhancing the host immune response of Sézary syndrome patients through the increased cytolytic activity of T and NK cells.

Abstract
CD4(+) T cells, in activated or malignant form, are involved in a number of diseases including inflammatory skin diseases such as psoriasis, and T cell lymphomas such as the majority of cutaneous T cell lymphomas (CTCL). Targeting CD4 with an antibody that inhibits and/or eliminates disease-driving T cells in situ may therefore be a useful approach in the treatment of inflammatory and malignant skin diseases. Depletion of CD4(+) T cells in intact inflamed human skin tissue by Zanolimumab, a fully human therapeutic monoclonal antibody (IgG1, kappa) against CD4, was studied in a human psoriasis xenograft mouse model. Zanolimumab treatment was shown to induce a significant reduction in the numbers of inflammatory mononuclear cells in upper dermis. This reduction in inflammatory mononuclear cells in situ was primarily due to a significant reduction in the numbers of skin-infiltrating CD4(+), but not CD8(+) CD3(+) T cells. The capacity of Zanolimumab to deplete the CD4(+) T cells in the skin may be of importance in diseases where CD4(+) T cells play a central role. Indeed, in a phase II clinical trial Zanolimumab has shown a dose-dependent clinical response in patients with CTCL and the antibody is currently in a phase III clinical trial for CTCL, a disease for which there is no safe and effective treatment available today.

Abstract
Measles virus (MV) has shown promise as an oncolytic virus in the treatment of different tumor models for human B-cell lymphoma, multiple myeloma, ovarian cancer, and glioma. We have shown that, in a phase I clinical trial, MV vaccine induces tumor regression in cutaneous T-cell lymphoma (CTCL) patients. Here, we investigated in detail, the effect of recombinant MV (rMV) vaccine strain in CTCL cell cultures, and in vivo in established CTCL xenografts in nude mice. The susceptibility of three CTCL cell lines, originating from patients, to rMV was tested by determination of cell surface expression of MV receptors. All cell lines expressed the receptors CD150 and CD46 and were easily infected by rMV and induced complete cell lysis. The cytoreductive activity was apparent in cells forming aggregates, indicating a cell-to-cell spread of MV and cytolysis owing to virus infection. Intratumoral (i.t.) injection of rMV, expressing enhanced green fluorescent protein induced complete regression of large established human CTCL tumors in nude mice, whereas tumors with control treatment progressed exponentially. Immunohistochemical analysis of tumor biopsies, after i.t. treatment, for MV-NP protein complex demonstrated replication of MV within the tumors. The data demonstrate the potential of MV as a therapeutic agent against CTCL.

Abstract
A 69-year-old Japanese man developed pruritus 3 years after beginning hemodialysis. Although eczema was not apparent at first, erythematous patches and plaques developed gradually on the affected skin. Secondary hyperparathyroidism was considered to be a main cause of this patient's pruritus, but skin lesions worsened even after parathyroidectomy had markedly decreased parathyroid hormone concentrations. Two months later, he developed an antibiotic-refractory fever of unknown origin and cervical, axillary, and inguinal lymphadenopathy. Elevations of soluble interleukin-2 receptor with 7410 U/mL and IgE with 24 600 U/mL in serum were noted, as was eosinophilia. The skin showed multiple slightly scaly patches and infiltrative plaques, which were reddish brown and distributed widely over the body surface except for the scalp and face. Mycosis fungoides, a cutaneous T-cell lymphoma, was diagnosed from biopsy specimens findings in skin and lymph node. Mycosis fungoides has not been documented as a cause of pruritus in hemodialysis patients. However, if skin lesions steadily worsen in hemodialysis patients, malignant diseases such as mycosis fungoides should be considered.

Abstract
Neoplastic T cells in mycosis fungoides (MF) are resistant to apoptotic agents, including galectin-1 that is abundant in skin. Although MF cells are typically CD7-, and thus galectin-1 resistant, CD7+ HH cells, derived from a patient with MF, were also resistant to galectin-1. HH cells demonstrate altered cell surface glycosylation, with loss of core 2 O-glycan ligands for galectin-1 created by core 2 beta1,6-N-acetylglucosaminyltransferase (C2GnT-I). Loss of core 2 O-glycans on tumor cells was also seen in primary CD7+ MF lesions. Surprisingly, HH cells are heterozygous for a C2GnT-I point mutation, yet this mutation resulted in a dramatic reduction in cellular glycosyltransferase activity. Expression of wild-type C2GnT-I in human HH cells, or murine lymphoma cells that lack C2GnT-I, restored core 2 O-glycan expression and susceptibility to galectin-1, whereas mutant enzyme lacked activity and did not restore core 2 O-glycan expression or susceptibility to galectin-1. Mutant enzyme did not have a dominant negative effect by affecting dimerization or activity of wild-type enzyme; rather, C2GnT-I haploinsufficiency is sufficient for loss of core 2 O-glycan expression and galectin-1 resistance. Thus, glycosyltransferase haploinsufficiency results in altered cellular glycosylation and resistance to cell death, identifying a new survival mechanism for T-lymphoma cells.

Abstract
Studies in an in vitro model of cutaneous T-cell lymphoma (CTCL) demonstrated that CTCL cell proliferation is stimulated by direct contact with autologous, immature dendritic cells (DCs), suggesting that CD4(+) CTCL cell division is driven by antigens presented by DC major histocompatibility complex (MHC) class 2. We now report that the T-cell receptor (TCR) of the CD4(+) CTCL cells is triggered after interaction with DCs loaded with apoptotic CTCL cells, as shown by reduced membrane expression of CD3 and the TCR, up-regulation of cytotoxic T lymphocyte antigen-4 (CTLA-4), and calcium mobilization. CTCL cells adopt a T-regulatory (Treg) phenotype expressing CD25/CTLA-4 and FoxP3 and secreting interleukin-10 (IL-10) and transforming growth factor-beta (TGF-beta). Treg CTCL cells suppress normal T-cell antigen-driven secretion of IL-2 and interferon-gamma (IFN-gamma). Blocking DC MHC class 2 expression or transport inhibited CTCL cell adoption of a Treg phenotype. Allogeneic CTCL cells or normal CD4 T cells served as sources of apoptotic material for CTCL cell conversion to a Treg phenotype. Conversion of CTCL cells to Treg cells may explain the anergic, immunosuppressive nature of the malignancy.

Abstract
Cutaneous lymphomas represent a heterogeneous group of T-, NK- and B-cell neoplasms, with mycosis fungoides (MF) being the most common subtype. MF has a plethora of clinicopathological manifestations. Many variants of this lymphoma differ substantially from the 'classical' Alibert-Bazin disease and are therefore sometimes referred to as 'atypical' forms of the disease. This review addresses the whole clinicopathological spectrum of mycosis fungoides with respect to epidemiology, clinical, histopathological, immunophenotypic and genotypic features and the clinical course and prognosis of its variants: classical, erythrodermic, follicular, syringotropic, bullous/vesicular, granulomatous, poikilodermic, hypo- and hyperpigmented, unilesional, palmoplantar, hyperkeratotic/verrucous, vegetating/papillomatous, ichthyosiform, pigmented purpura-like, pustular and mucosal involvement in MF.

Abstract
Sézary syndrome (Sz) is a malignancy of CD4+ memory skin-homing T cells and presents with erythroderma, lymphadenopathy, and peripheral blood involvement. To gain more insight into the molecular features of Sz, oligonucleotide array analysis was performed comparing gene expression patterns of CD4+ T cells from peripheral blood of patients with Sz with those of patients with erythroderma secondary to dermatitis and healthy controls. Using unsupervised hierarchical clustering gene, expression patterns of T cells from patients with Sz were classified separately from those of benign T cells. One hundred twenty-three genes were identified as significantly differentially expressed and had an average fold change exceeding 2. T cells from patients with Sz demonstrated decreased expression of the following hematopoietic malignancy-linked tumor suppressor genes: TGF-beta receptor II, Mxi1, Riz1, CREB-binding protein, BCL11a, STAT4, and Forkhead Box O1A. Moreover, the tyrosine kinase receptor EphA4 and the potentially oncogenic transcription factor Twist were highly and selectively expressed in T cells of patients with Sz. High expression of EphA4 and Twist was also observed in lesional skin biopsy specimens of a subset of patients with cutaneous T cell lymphomas related to Sz, whereas their expression was nearly undetectable in benign T cells or in skin lesions of patients with inflammatory dermatoses. Detection of EphA4 and Twist may be used in the molecular diagnosis of Sz and related cutaneous T-cell lymphomas. Furthermore, the membrane-bound EphA4 receptor may serve as a target for directed therapeutic intervention.

Abstract
Treatment of mycosis fungoides (MF) is indicated to reduce symptoms, improve clinical appearance, prevent secondary complications, and prevent progression of disease, all of which may have an impact on survival. Treatment of MF includes topical and systemic therapies, which can be administered alone or in combination. Psoralen and ultraviolet A radiation is effective in early-stage MF, inducing complete remissions in most patients. Psoralen and ultraviolet A radiation may also be combined with low doses of interferon (IFN)-alpha to treat stage I/II disease. However, early aggressive therapy with radiation and chemotherapy does not improve the prognosis. Local radiotherapy or total skin electron beam irradiation has been used with success to control advanced skin disease. Extracorporeal photopheresis may also be used successfully, but it is not generally available. Once the disease becomes refractory to topical therapy, IFN-alpha single-agent or combination chemotherapy may be administered, but the duration of response is often less than 1 year and ultimately all patients will relapse and become refractory. Among chemotherapeutic agents, pentostatin, gemcitabine, and liposomal doxorubicin seem to be particularly effective. Response rates after combined modality therapy with total skin electron beam irradiation and chemotherapy/IFN-alpha appear similar to response rates of chemotherapy alone. Therefore, there is a great need for the further development of novel emerging treatment modalities, such as retinoids (ie, bexarotene) and immunotherapeutic agents (ie, cytokines, tumor vaccines, and monoclonal antibodies), all of which appear to have significant therapeutic potential in patients with MF. Biologically based therapies may reduce the need for genotoxic therapies, such as cytostatics and radiotherapy.

Abstract
Patients with advanced cutaneous T-cell lymphoma (CTCL) exhibit profound defects in cell-mediated immunity. Host immune functions appear to play an integral role in mediating disease-controlling responses in CTCL, therefore we investigated the effects of synthetic oligode-oxynucleotides with CpG motifs (CpG ODN), which have been recognized as immune stimulatory by virtue of activation of dendritic cells (DCs) following binding to Toll-like receptor (TLR) 9. Peripheral blood mononuclear cells (PBMCs) from patients with advanced CTCL (erythroderma with circulating malignant T cells) and healthy volunteers were cultured with either CpG-A or CpG-B ODN. Patients' PBMCs exhibited marked induction of interferon-alpha (IFN-alpha) release following culture with CpG-A. Similarly significant activation of NK cells and CD8 T cells occurred as assessed by up-modulation of CD69 expression and by natural killer lytic activity. Nevertheless, the PBMCs of patients exhibited blunted responses to CpG-A compared to healthy volunteers. In such cases, IL-15 was capable of producing levels of NK activation that were superior to CpG-A, while the combined effects of CpG-A plus IL-15 induced maximal activation of NK cells and further enhanced activation of CD8 T cells. These findings have important implications for the potential enhancement of antitumor immunity among patients with advanced CTCL.

Abstract
Interferons are polypeptides with a broad range of in vivo effects that have shown efficacy in cutaneous T-cell lymphoma (CTCL). Particularly useful is alfa interferon (IFN) which, as a single agent, has shown partial remission rates of > 50% and complete responses of > 20%. Side-effects are predictable, generally well tolerated and dose-related. The efficacy of IFN has increased with combination therapy without any significant increase in attendant side-effects. An update on the specifics of the different IFN subtypes, their inherent biologic activity, pharmacokinetics, efficacy and safety in CTCL is presented in this paper.

Abstract
Topical nitrogen mustard (mechlorethamine, NM) has been used as primary therapy for management of patients with mycosis fungoides (MF) since the 1950s. Many investigators have demonstrated the efficacy of topical NM in patch and/or plaque disease of MF. Updated results from Stanford also confirm the clinical efficacy. The complete response (CR) rates reported are 76-80% for patients with limited patch/plaque (stage IA), and 35-68% for those with generalized patch/plaque (stage IB) disease. Topical NM can be used as an aqueous (water) or ointment-based preparation. The efficacy results are similar in patients who were treated with aqueous versus ointment preparations. Maintenance regimens used are variable, but there is no data to suggest that a longer maintenance duration results in greater potential for long-term remission. Most patients who achieve initial CR with topical NM tend to require NM-only for disease management. Topical NM is equally effective when used as salvage therapy with disease relapse. The most common toxicity of topical NM therapy is contact irritant or allergic reaction. The potential for allergic reaction is significantly reduced (< 10%) when NM is used as an ointment preparation. The potential for secondary skin cancer development is increased in patients who have used multiple sequential topical skin-damaging therapies or NM in the genital skin, but not in patients who have used NM as monotherapy (avoiding genital skin application). Topical NM is used safely in pediatric patients and there is no evidence of any clinically significant systemic absorption of topically applied NM.

Abstract
Cutaneous T-cell lymphoma (CTCL) is a malignancy of skin-homing T cells. A major feature of CTCL is profound immunosuppression, such that patients with advanced mycosis fungoides or Sézary syndrome have been compared with patients with advanced HIV disease and are susceptible to opportunistic infection. The etiology of this immunosuppression is unclear. We analyzed peripheral blood T cells of patients with CTCL with stage I to IV disease, using a sensitive beta-variable complementarity-determining region 3 spectratyping approach. Our data revealed a profound disruption of the complexity of the T-cell repertoire, which was universally observed in patients with advanced disease (stages III and IV), and present in up to 50% of patients with early-stage disease (stages I and II). In most patients, multiple monoclonal and oligoclonal complementarity-determining region 3 (CDR3) spectratype patterns in many different beta-variable families were seen. Equally striking was a reduction of normal T cells (as judged by absolute CD4 counts) across multiple beta-variable families. In general, CTCL spectratypes were reminiscent of advanced HIV spectratypes published elsewhere. Taken together, these data are most consistent with a global assault on the T-cell repertoire in patients with CTCL, a process that can be observed even in early-stage disease.

Abstract
Despite well-defined and immunogenic tumor antigens, and even in the presence of tumor antigen-specific cytotoxic cells, the immune system does not appear to be very effective in eradicating cells that have undergone malignant transformation. Tumor cells, even though invading and representing a threat, are not truly "foreign" but autologous cells that have become transformed in a subtle way, enabling them to escape the host immune system. Melanoma, and to less extent nonmelanoma, skin cancers have developed different strategies to circumvent host immunosurveillance. HLA-G is one of the molecules implicated in cancer immunescape. This review will concentrate on induction and expression of this nonclassical class I molecule in different skin cancer types presenting existing experimental evidence on this topic.

Abstract
This chapter describes the various ways in which the non-Hodgkin's lymphomas can involve the skin, how these diseases should be assessed, standard treatments available in 2002, and new directions in research. The goal of the session is to succinctly review recent developments in lymphoma classification and treatment as they apply to the unique aspects of lymphoma when manifest in the skin. In Section I, Dr. Eric Hsi reviews the special characteristics of the lymphomas seen when they proliferate in the skin and the application of the new World Health Organization classification system to the cutaneous lymphomas, emphasizing the unique challenges of recognizing and correctly classifying these diseases. He summarizes the evidence in favor of including the skin lymphomas in the overall lymphoma classification scheme and concludes with a practical description of the specific skin lymphoma entities. In Section II, Dr. Joseph Connors describes the current optimal treatment of the B-cell lymphomas when they present in or metastasize to the skin. Building on the classification scheme described by Dr. Hsi, Dr. Connors outlines a treatment approach based on current understanding of pathophysiology of these diseases and application of each of the effective modalities available for cutaneous lymphoma including radiation, chemotherapy, and immunotherapy. In Section III, Dr. Francine Foss concludes the session with a discussion of the different T-cell lymphomas that start in or spread to the skin concentrating on mycosis fungoides, cutaneous anaplastic large cell lymphoma and peripheral T-cell lymphoma. She includes comments on the newer anti-T-cell chemo- and immuno-therapeutics focusing on agents and techniques specific for cutaneous T-cell lymphomas.

Abstract
BACKGROUND There is evidence that a T-helper (Th) 2 cytokine pattern dominates in the peripheral blood as well as in tissue of patients with Sézary syndrome (SS), and that the malignant clone is of Th2 phenotype. However, there are conflicting studies on the cytokine pattern in the peripheral blood in different stages of cutaneous T-cell lymphoma (CTCL). OBJECTIVES To examine, by means of flow cytometry (FC), the Th1/Th2 cytokine profile [cytoplasmic interferon (IFN)-gamma/interleukin (IL)-4] in peripheral blood T cells from patients with mycosis fungoides (MF) and SS, the most common forms of CTCL, and to correlate their expression with clinical stage, clonality and T-cell immunophenotype changes in order to evaluate their relevance in CTCL progression. METHODS We investigated by FC the percentage of CD3+ T cells expressing cytoplasmic IFN-gamma and IL-4 after stimulation in blood specimens of 43 CTCL patients (32 stage I-II and 11 stage III-IV), eight of whom were erythrodermic. Next, we compared cytoplasmic IFN-gamma and IL-4 expression between patients of different stages and controls, and correlated our findings to T-cell receptor (TCR)-gamma gene rearrangement, used as a marker of clonality, and changes in T-cell immunophenotype (CD4+, CD8+, CD4+/CD7-, CD4+/CD25+) and natural killer cells. Polymerase chain reaction amplification of the TCR-gamma gene was performed in 41 blood and 26 skin specimens. We also examined the cytokine expression pattern in patients with erythrodermic MF and SS. RESULTS A significantly higher frequency of CD3+/IL-4+ T cells was found in late (III-IV) compared with early (I-II) CTCL patients (P = 0.002) or controls (P < 0.001). There were significant positive correlations between the percentages of CD3+/IL-4+ and the percentages of CD3+/CD4+ T cells (r = 0.385, P = 0.05), CD4+/CD7- T cells (r = 0.335, P < 0.05) and CD4+/CD25+ T cells (r = 0.433, P = 0.01); there was a negative correlation between the percentages of CD3+/IL-4+ and CD3+/CD8+ T cells (r = -0.463, P = 0.005) and a positive correlation between the percentages of CD3+/IFN-gamma+ and CD3+/CD8+ T cells (r = 0.368, P = 0.02). Increased percentages of CD3+/IL-4+, CD3+/CD4+ and CD4+/CD7- T lymphocytes were associated with the presence of clonality (P = 0.025, P < 0.001 and P = 0.0031, respectively). All independent variables showed a statistically significant difference between SS and erythrodermic MF patients, or controls, apart from cytoplasmic IL-4, which was high both in erythrodermic MF and SS patients compared with controls (P = 0.003 and P = 0.008, respectively). In multiple regression logistic analysis, the probability of belonging to advanced CTCL stages was associated only with increased cytoplasmic IL-4 (P = 0.007, odds ratio 1.13, 95% confidence interval 1.033-1.229). CONCLUSIONS Increased T-cell cytoplasmic IL-4 is more frequent in late CTCL stages, correlates with T-cell immunophenotype changes found in advanced disease and is associated with clonality. Increased cytoplasmic IL-4 is frequent both in erythrodermic MF and SS patients, in contrast to other variables found increased only in SS, suggesting that IL-4 may be an early indicator of disease progression. Moreover, our results show that increased cytoplasmic IL-4 is the sole predictor of advanced CTCL disease and confirm the relevance of FC determination of IL-4 in the routine evaluation of CTCL cases.

Abstract
Constitutive E-selectin expression on dermal microvascular endothelial cells plays a critical role in mediating rolling adhesive interactions of human skin-homing T cells and in pathologic accumulation of lymphocytes in skin. The major E-selectin ligand on human skin-homing T cells is cutaneous lymphocyte-associated antigen (CLA), a specialized glycoform of P-selectin glycoprotein ligand-1 (PSGL-1) defined by monoclonal antibody HECA-452. Since HECA-452 reactivity, and not PSGL-1 polypeptide itself, confers the specificity of human T cells to enter dermal tissue, inhibition of HECA-452 expression is a potential strategy for modulating lymphocyte migration to skin. In this study, we examined the efficacy of several well-characterized metabolic inhibitors of glycosylation and of a novel fluorinated analog of N-acetylglucosamine (2-acetamido-1,3,6-tri-O-acetyl-4-deoxy-4-fluoro-D-glucopyranose [4-F-GlcNAc]) to alter HECA-452 expression on human CLA(+) T cells and prevent cell tethering and rolling on selectins under shear stress. At concentrations that did not affect PSGL-1 expression, we found that swainsonine (inhibitor of complex-type N-glycan synthesis) had no effect on HECA-452 expression or selectin ligand activity, whereas benzyl-O-N-acetylgalactosamide (BAG; inhibitor of O-glycan biosynthesis) ablated HECA-452 expression on PSGL-1 and significantly lowered selectin ligand activity. We found that 4-F-GlcNAc (putative inhibitor of poly-N-acetyllactosamine biosynthesis) was more potent than BAG at lowering HECA-452 expression and selectin binding. In addition, we show that 4-F-GlcNAc was directly incorporated into native CLA expressed on T cells, indicating direct inhibition on poly-N-acetyllactosamine elongation and selectin-binding determinants on PSGL-1 O-glycans. These observations establish a potential treatment approach for targeting pathologic lymphocyte trafficking to skin and indicate that 4-F-GlcNAc may be a promising agent for treatment of dermal tropism associated with malignancies and inflammatory disorders.

Abstract
The neoplastic cells of mycosis fungoides (MF) and Sézary syndrome are recognized to be clonal expansions of "memory" T cells that home into the upper dermis and epidermis via the interplay of adhesion molecules and chemokines, and this may account for the marked effectiveness and even curative potential of various skin-directed therapies utilized to treat clinically early disease. However, because neoplastic T cells freely circulate and are detectable in extracutaneous tissues by PCR prior to other methods, effective long-term control of more advanced MF and Sézary syndrome, i.e. reduction of tumor burden and decreased risk of transformation into aggressive lymphoma, often requires long-term administration of a therapy with systemic activity in addition to skin-directed therapies. Therapies with immunomodulatory activities, e.g. interferon alfa, bexarotene or extracorporeal photochemotherapy (ECP), are probably superior to traditional cytotoxic drugs in this regard although the response rates are relatively low. Selected patients with advanced or biologically aggressive CTCL should be considered for an allogeneic stem cell transplantation regimen to induce a graft-versus-tumor response. New and emerging treatments include immunotoxins such as denileukin diftitox that selectively target neoplastic T cells, potent immunomodulatory cytokines such as rIL-12 to enhance innate antitumor immune mechanisms, novel immunotherapeutic approaches that use dendritic cells loaded with tumor-associated antigens or vaccination using synthetic peptides or DNA plasmids that express the variable region of the T cell receptor beta chain, and possibly gene and protein transduction therapy to correct intracellular defects in neoplastic T cells. Overall the future of therapy for CTCL seems quite optimistic.

Abstract
Cutaneous T cell lymphoma is a clonally derived, skin-invasive malignancy of CD4+ T lymphocytes with the phenotype of mature helper T cells. Previous work has demonstrated that the Sézary form, or typically leukemic form of cutaneous T cell lymphoma, is characterized by prominent immunologic defects, including depressed cell-mediated immunity associated with marked defects in the production of interleukin-12 and other type 1 helper T cell cytokines. Recent clinical trials with recombinant human interleukin-12 for cutaneous T cell lymphoma have demonstrated that it is a potent therapeutic agent, which induces cytotoxic T cell responses. Nevertheless, a high rate of refractoriness to recombinant human interleukin-12 occurred in these studies that may be related to the downmodulation of interleukin-12 receptor expression by chronic interleukin-12 use. In an effort to enhance the overall response rate and to overcome the refractoriness to recombinant human interleukin-12 therapy, we studied the immunologic effects in vitro of adding interleukin-2 to interleukin-12 as a model to achieve these goals. We examined the stimulation of interferon-gamma production, natural killer cell activity and interleukin-12 receptor expression by T cells of cutaneous T cell lymphoma patients. The addition of interleukin-12 to cutaneous T cell lymphoma patient peripheral blood cells resulted in the production of interferon-gamma (mean = 7914 pg per ml +/- 2161, n = 15) as did interleukin-2 alone (mean = 7222 pg per ml +/- 2228, n = 15). Importantly, the addition of interleukin-2 to the interleukin-12 synergistically enhanced the levels of interferon-gamma produced (mean = 16 792 pg per ml +/- 2492 n = 15) (p <0.01). Similarly, addition of interleukin-2 to interleukin-12 synergistically enhanced both the natural killer cell activity of 15 cutaneous T cell lymphoma patients as well as T cell surface interleukin-12 receptor expression in comparison with the effects of interleukin-12 or interleukin-2 alone. Thus, interleukin-2 plus interleukin-12 unequivocally produces the synergistic enhancement of multiple parameters of cell-mediated immunity as well as upmodulating interleukin-12 receptor expression; this indicates that protocols combining these two potent immune enhancing cytokines may have added therapeutic benefit for cutaneous T cell lymphoma.

Abstract
Primary cutaneous lymphomas (CLs) constitute a spectrum of diseases characterized by a clonal accumulation of lymphocytes in the skin. Most CLs display a T(h)2 cytokine profile, including expression of interleukin-10 (IL-10). Because the up-regulation of HLA-G, a nonclassical class Ib molecule inducible by IL-10, might account for the immunescape of the malignant clone, HLA-G and IL-10 expression has been investigated in 45 cases of primary CL (10 of B-cell and 35 of T-cell origin) with quantitative polymerase chain reaction (PCR) and immunohistochemistry. HLA-G message was present in all cutaneous B-cell (CBCL) and T-cell (CTCL) lymphomas evaluated. Immunohistochemistry revealed HLA-G protein expression in 23 (51%) of 45 cases (7 of 10 CBCL, 16 of 35 CTCL). While in CBCL mostly indolent types displayed HLA-G positivity, in CTCL HLA-G expression was associated with high-grade histology and advanced stage of the disease. Except for neoplastic and infiltrating lymphocytes, other cells such as macrophages and dendritic cells showed HLA-G immunoreactivity. Furthermore, IL-10 protein expression was demonstrated in 16 (73%) of 22 HLA-G(+) cases, which correlated with HLA-G protein presence (P <.001). HLA-G up-regulation together with IL-10 expression in CL might additionally contribute to the evasion of immunosurveillance and facilitate the transition from low- to high-grade lymphomas.

Abstract
During the most recent decades, much knowledge has been gained concerning the immunologic and pathologic mechanisms of CTCL. The development of immunomodulators aimed at correcting aberrations in immunology and cellular growth and differentiation reflects this increased understanding. This review of the currently available immune-response modifying drugs shows that recombinant forms of natural cytokines and retinoids can be developed with tolerable toxicity profiles and substantial efficacy. Although milestone drugs such as bexarotene have been approved by the FDA- for treatment of CTCL, other agents such as IL-12 may also have a place in treatment of the disease. Even though unapproved, IFN-alpha may be the most active single immunomodulating agent against CTCL. It seems that further delineation of CTCL cytokine profile changes and immunologic aberrations are key in developing effective immunomodulators that are able to reverse these alterations.

Sézary T cell-activating factor (SAF) was originally defined as an inducer of functional interleukin-2 (IL-2) receptors on normal and malignant T cells in patients suffering from Sézary syndrome. In fact, a combination of SAF and IL-2 stimulated the propagation of T cell lines from the peripheral blood mononuclear cells (PBMC) of those patients, with approximately one third of those cell lines containing the predominant malignant clone as determined via cytogenetic and/or T cell receptor gene rearrangement analysis. Although the primary source of SAF was mitogen-stimulated PBMC of a patient with Sézary syndrome, we were unable to isolate the gene encoding SAF from eukaryotic libraries. However, we observed SAF activity in the cytoplasm of one of the malignant cell lines in a complex containing RNA and DNA. This observation led us to consider the possibility that SAF is not of eukaryotic origin. Intracellular pathogens replicate in the cytoplasm of host cells and contain proteins, DNA, and RNA. Using a panel of antichlamydial antibodies with confirmation from polymerase chain reaction primers, we found that most patients with mycosis fungoides were positive for these determinants. Immunoelectron microscopy and protein blotting further confirmed antibody reactivity. We showed that Chlamydia pneumoniae were capable of infecting normal human keratinocytes in culture. We also demonstrated that C. pneumoniae antigen expression was associated with active disease because these determinants were not expressed after psoralen and ultraviolet A therapy. We hypothesize that chronic infection by C. pneumoniae leads to expansion of C. pneumoniae-specific T cells, thereby potentiating the development of cutaneous T cell lymphoma.

Abstract
CD7, a molecule normally expressed on 90% of normal CD4+ T cells, is often deficient on the malignant T cells of cutaneous T cell lymphoma. To investigate the clinical and biologic implications of CD7 expression, blood lymphocytes from 42 patients with the leukemic phase of cutaneous T cell lymphoma (CD4/CD8 ratio of 10 or more with evidence of a T cell clone in the blood) were analyzed for level of expression of CD7 by flow cytometry. CD7 expression by cells did not clearly segregate into two distinct subgroups that are either CD7 positive or CD7 negative as generally thought; however, nine of 17 patients with a predominantly CD4+CD7+ tumor population on early studies became CD4+CD7- over time whereas the converse situation was not observed. In addition, of three patients with evidence of large tumor cells in the blood coexisting with smaller cells, discordant CD7 expression was observed in one instance. In lymph node specimens, the percentage of cells expressing CD7 and other T cell markers did not correlate with histologic evidence of involvement. CD7 expression on blood lymphocytes also did not correlate with patients' survival nor to serum IgE levels or blood eosinophil counts, a finding suggesting that this marker does not identify functional cell subsets that produce serum interleukin-4 or -5, respectively. We speculate that the level of CD7 expression on malignant T cells may be the effect of sustained antigen stimulation in vivo analogous to what has been proposed to occur with normal T cells during aging.

Abstract
BACKGROUND Cutaneous T-cell lymphoma (CTCL) is a clonally derived, skin-invasive malignancy of CD4(+) T lymphocytes with the phenotype of mature helper T cells. Advancing stages of CTCL are associated with depressed cell-mediated immunity, increased production of T helper type 2 cytokines and decreased levels of T helper type 1 cytokines. OBJECTIVE Our purpose was to evaluate the cytokine secretion pattern and cell-mediated cytotoxicity in peripheral blood mononuclear cells of patients with Sézary syndrome in relation to the presence of the malignant clone. METHODS Serial polymerase chain reaction for the T-cell receptor-beta or T-cell receptor-gamma gene rearrangement was used to determine the presence of the malignant clone. Enzyme-linked immunosorbent assays were used to determine the levels of interleukin 4 and interferon gamma produced by the peripheral blood mononuclear cells from the patients with Sézary syndrome. RESULTS We demonstrate 3 cases of Sézary syndrome with typically suppressed cell-mediated cytotoxicity, elevated production of interleukin 4, and depressed production of interferon gamma by their peripheral blood mononuclear cells before institution of therapy with biologic response modifier therapy. In all 3 cases after clinical and molecular remission, we observed striking immunologic changes, including an increase in levels of natural killer cell activity and interferon gamma production and decreased production of interleukin 4. CONCLUSIONS The observation that the cytokine secretion pattern by peripheral blood mononuclear cells from 3 patients with Sézary syndrome normalized with the disappearance of the malignant clone from the peripheral blood suggests that the malignant T cells account for the aberrant cytokine production. Moreover, the aberrant cytokine production may be the cause for suppression of cell-mediated immunity seen in advancing stages of CTCL.

Abstract
Initial phase I and II clinical trials with recombinant human interleukin-12 have demonstrated the therapeutic efficacy of this cytokine in early stage cutaneous T cell lymphoma as compared with more advanced stages such as the leukemic Sézary syndrome. In an effort to optimize the use of recombinant human interleukin-12, using flow cytometry we studied the regulation of the interleukin-12 receptor beta1 (high affinity chain) and beta2 (chain necessary for interleukin-12 signal transduction) on normal volunteer CD4+ and CD8+ T cells and CD4+ and CD8+ cells from eight patients with different degrees of leukemic involvement with Sézary syndrome. The beta1 chain was not readily detectable on resting normal and T cells from Sézary patients, but expression was induced following T cell activation with phytohemagglutinin. Similarly, the beta2 chain was not detectable on resting normal volunteer T cells, but could be induced following phytohemagglutinin stimulation. Moreover, the beta2 chain on normal volunteer T cells was markedly upregulated following short-term culture with interferon-gamma or recombinant human interleukin-12. CD8+ T cells routinely exhibited a greater expression of beta2 than did CD4+ T cells. In marked contrast, both CD4+ and CD8+ T cells from patients with Sézary syndrome and a high tumor cell burden (> 50% circulating atypical Sézary T cells) failed to express the beta2 chain under any culture conditions. Although, culture with anti-interleukin-10 also markedly increased beta2 expression on normal volunteer T cells, this failed to induce expression on either CD4+ or CD8+ T cells from Sézary patients and a high tumor burden. Investigation of patients with Sézary syndrome and a low tumor cell burden (< 15% circulating Sézary T cells) revealed a pattern of beta2 expression that was intermediate between advanced Sézary syndrome and normal volunteers. Both CD4+ and CD8+ peripheral blood T cells from these earlier stage patients were induced to express the beta2 chain, although at a lower frequency of positivity than T cells from normals, following culture with phytohemagglutinin, interferon-gamma, recombinant human interleukin-12, or anti-interleukin-10. These results indicate that short-term culture with interferon-gamma and recombinant human interleukin-12 potently upregulates beta2 chain expression on T cells from normal volunteers, whereas a similar, but less marked effect occurs on T cells from Sézary syndrome patients and a low circulating tumor cell burden. In contrast, the beta2 chain appears to be suppressed on both CD4+ and CD8+ T cells from Sézary patients with a heavy circulating tumor cell burden and it is not induced by interferon-gamma or recombinant human interleukin-12. Therefore, recombinant human interleukin-12 is likely to be most effective for early stage cutaneous T cell lymphoma due to a greater display of beta2 receptors on responding CD8+ anti-tumor cytotoxic T cells.

Abstract
The clinical experience with bexarotene for cutaneous T-cell lymphoma (CTCL) at our center is reviewed here. Disease activity assessment was monitored every 4 weeks in all patients. Five target lesions were monitored, an area score was performed, and a CTCL-specific health assessment questionnaire was administered. Four patients with refractory plaque CTCL were treated with bexarotene gel. All target lesions disappeared after 8 weeks of therapy, with recurrences observed in untreated areas. In the follow-up period, no recurrences of the original target lesions were observed. One patient withdrew from the study. Patients with refractory patch/plaque disease were randomized to a high-dose (300 mg/m(2)) or low-dose (6.5 mg/m(2)) daily oral regimen of bexarotene. After showing disease progression, the two patients on the low-dose arm were entered into the high-dose arm after 8 weeks. Marked clinical responses were seen in all patients treated. The target lesions showed either complete disappearance or a reduction in lesion size, duration, and scale. No new lesions were noted in patients on high-dose bexarotene. Self-assessments also confirmed the palliative properties of the observed responses. All patients had hypertriglyceridemia despite the concomitant administration of atorvastatin at 60 mg/day. Dose reductions were required to maintain safe lipid levels. Four patients with erythrodermic CTCL were treated with high-dose oral therapy, and all patients showed rapid (within 2 weeks) improvement of erythroderma and symptoms.

Abstract
PURPOSE Primary cutaneous T-cell lymphomas (CTCLs) encompass a wide variety of lymphomas that are characterized by the localization of the malignant lymphocytes to the skin at presentation. Advances in molecular biologic techniques, including immunophenotyping and gene rearrangement studies to determine clonality, have led to more frequent diagnosis of CTCL as well as more consistent subclassification of these entities. However, there continues to be confusion in the classification, prognosis, and management of patients with CTCL. The purpose of this review is to present a summary of the diagnosis, prognosis, and treatment of CTCL, with specific emphasis on mycosis fungoides (MF) and Sézary syndrome (SS). We also present a detailed discussion of the entities that make up the differential diagnosis of CTCL. DESIGN We reviewed the medical literature on CTCL and other diseases that make up the differential diagnosis of CTCL. RESULTS AND CONCLUSION MF and SS are the most common forms of CTCL. The etiology of this disease is still unknown. Patients may go for months to years with skin abnormalities before being diagnosed. MF/SS is an indolent disease and patients with T1 disease have a normal life expectancy. Patients who undergo transformation to large-cell lymphoma (8% to 23% of patients) have a poor prognosis, with mean survival ranging from 2 to 19 months. Treatment for MF/SS continues to be palliative. There are many new therapies that are currently being investigated in clinical trials, and the DAB(389)IL-2 fusion protein was recently approved for the treatment of refractory MF/SS.
