Abstract
We demonstrated that percutaneous peptide immunization by way of skin with impaired barrier function is a simple and noninvasive strategy to generate effective immune responses against tumors. This therapeutic strategy seems to be beneficial for the treatment of skin-associated malignancies, including CTCL, because specific CTLs are considered to be well-induced in lymph nodes that neighbor barrier-disrupted skin (Fig. 3). There remain unsolved issues concerning (1) the ability of cytokines and growth factors to enhance efficacy of this therapy and (2) the time schedule of clinical trials. It was recently shown that application of antigenic protein or its coding DNA to skin with increased permeability yields antigen-specific antibody responses. Because the skin represents an easily accessible site for immunization and vaccination, percutaneous immunization using corneum barrier-disrupted skin is an alternative to injection of CTL-inducing molecules and can readily be exploited for cancer treatment in humans. The effective induction of CTLs suggests that the method that uses barrier-disrupted skin can potentially be applied to treatments of virus and helminth infections with the use of certain antigenic peptides.

Abstract
Phototherapy has been utilized for decades in the treatment of various dermatologic conditions, including cutaneous T-cell lymphoma (CTCL). Currently, a number of light sources are available, and selection of the specific modality is based on a number of factors, the most important of which is disease stage. The efficacy of broadband ultraviolet B (UVB) is limited to the patch stage, while psoralen and ultraviolet A (PUVA) is capable of clearing plaques and, sometimes, early tumors. Narrowband UVB is also effective for early stages and has practical advantages over PUVA, but more studies are needed to more fully evaluate its role in CTCL. Long-wave ultraviolet A (UVA1) has likewise shown efficacy, supported by findings of apoptosis induction in UVA1-treated cells. Long-term remissions have been reported for PUVA, but in the majority of cases, maintenance therapy was necessary. Although beneficial as monotherapy for early stages of the disease, phototherapy is also a useful adjunct to other modalities such as interferons, retinoids and electron beam therapy. Studies are ongoing to refine protocols for combination therapy, with the goal of improving efficacy, while minimizing adverse effects.

Abstract
Photopheresis or extracorporeal photochemotherapy (ECP) is an immunomodulating procedure that has been available for the treatment of cutaneous T-cell lymphoma (CTCL) since 1987. A concentrated white blood cell (WBC) sample spiked with 8-methoxypsoralen (methoxsalen) is exposed to an ultraviolet A light source, then all blood components are returned to the patient. Treatment of mycosis fungoides (MF) and Sézary syndrome (SS) with ECP has been reported in over 400 patients. The combined overall response rate for all stages of CTCL is 55.7% (244 out of 438) with 17.6% (77 out of 438) achieving a complete response. Efficacy in treating certain clinical stages (IB, IIA, III and IVA) and skin stages (T2 and T4) of MF and SS is favorable, although randomized trials comparing ECP to other standard therapies are needed. The use of ECP to treat early stage patients remains controversial. Efforts to establish the effectiveness of combining ECP with other newer immunoadjuvant therapies and modifications of the procedure to enhance immunomodulation are exciting prospects for patients with CTCL.

Abstract
Although most patients who have cutaneous T-cell lymphoma have an indolent clinical course, patients who have cutaneous tumors, lymph node or visceral involvement, or peripheral blood involvement generally have rapidly progressive disease with shorter survival. In those patients with poor prognostic features, conventional combination chemotherapy is usually ineffective. High-dose chemotherapy with autologous hematopoietic stem cell transplant (HSCT) results in high remission rates, but the recurrence is inevitable and rapid. Allogeneic HSCT, in contrast, provides durable long-term remissions and is currently the only potentially curative therapy.

Abstract
Although the need for a specific QOL index for MF/SS has been recognized, little work has been done in this area. QOL instruments should address general health concepts, as well as specific issues that are relevant to patients who have MF/SS; a combination of two instruments may be appropriate. Confirming the validity, reliability, and responsiveness to change of a combination of QOL instruments, such as SKINDEX-29 and FACT-G, in patients who have MF/SS will be relevant. For patients who have MF/SS, focusing our efforts on improving the disease and their QOL should translate into improvements that are meaningful to them. Thus, our goal should be to incorporate the findings of QOL research into practice and use the results to guide our practices, as they relate to therapy. Some important considerations are: We must be explicit about what will be done with the information that is obtained about an individual's QOL. We should consider what additional knowledge QOL measures provide that we could not otherwise have. We should be ready for unexpected results, as exemplified by instances where aggressive therapy could result in improved QOL. Although challenges exist in moving forward QOL research in CTCL, the words of wisdom of Tannock bring the concept of QOL into perspective: "When cure remains elusive, it is time to start treating the patient, not just the tumor." A final consideration is that we should not forget the dimension of spirituality, which is especially relevant to patients who have advanced MF/SS. Spirituality is characterized by the capacity to seek purpose and meaning, to have faith, to love, to forgive, and to see beyond current circumstances. Spirituality enables a person to rise above suffering. Unfortunately, research on spirituality is scarce, in part, because of the difficulty in assessing spiritual suffering. Nevertheless, physicians who are caring for patients who have advanced MF/SS should acknowledge the spiritual dimension as an integral component of the dying process.

Abstract
Effective long-term management of cutaneous T-cell lymphoma (CTCL) requires administration of skin-directed therapies such as topically applied nitrogen mustard or photochemotherapy to achieve a complete response in clinically early disease (patch and thin-plaque-phase mycosis fungoides, MF) and often the concomitant administration of well-tolerated drugs with systemic effects such as interferon alfa, bexarotene, methotrexate or extracorporeal photopheresis in more advanced, but not highly aggressive/nontransformed disease (thick plaque or tumor phase MF or erythrodermic CTCL). The author's approach is provided as a guide for dermatologists in private practice.

Abstract
Cutaneous T cell lymphomas (CTCLs) are lymphoproliferative disorders involving the skin. Malignant cells have a CD4+ T-helper phenotype and are found in early stages of the disease in plaques and cutaneous tumors. MLV/HIV-pseudotyped retroviral vectors target gene transfer to CD4-positive T cells and are therefore well suited to be specific delivery vehicles to treat CTCLs. We established a mouse xenograft model for CTCL and generated MLV/HIV-pseudotyped vectors encoding the herpes simplex virus thymidine kinase (HSV-TK), a well-known suicide gene, to prove the efficacy of MLV/HIV vectors in CTCL treatment. Vector particles were intratumorally injected into CTCL nude mouse xenografts. Mice were systemically treated with ganciclovir (GCV) and the tumor tissue was analyzed. A significant delay in tumor growth was observed for HSV-TK-transduced and GCV-treated tumors. GFP expression could be detected exclusively in CD4+ cells of tumors after transduction with GFP-encoding control vectors. The data demonstrate a cell-specific in vivo gene delivery via MLV/HIV-pseudotyped vectors and open new avenues for the treatment of CTCL in humans.

Abstract
Mimotopes provide an alternative to natural T cell epitopes for cancer immune therapy, as they can recruit and stimulate T cell repertoires that deviate from the repertoires engaged with the tumor and exposed to disease-related immune suppression. Here, mimotopes of a shared tumor-associated T cell epitope in cutaneous lymphoma were tested for their capacities to induce clinical and immunological responses in cancer patients. The mimotope sequences had been determined by a combinatorial peptide library approach without knowledge of the corresponding natural tumor-associated antigen. Vaccination with these mimotopes together with helper T cell-inducing antigens led to complete tumor remission in the two patients tested. After each booster vaccination, enhanced frequencies of mimotope-specific CD8+ T cells were detected in the peripheral blood of the patients, and the CTL proved to be cytotoxic and tumoricidal when tested in vitro. These data provide a first indication of clinical efficacy of mimotopes in cancer patients.

Abstract
To investigate the involvement of reactive oxygen species in extracorporeal photoimmunotherapy (photopheresis), we have introduced two highly sensitive and specific techniques for the detection and quantitative measurement of oxygenated nonenzymatically formed arachidonic acid isomers [mono-hydroxyeicosatetraenoic acids (HETEs) and F2-isoprostanes] by gas chromatography-mass spectrometry/negative ion chemical ionization (GC-MS/NICI) in plasma samples of patients suffering from cutaneous T-cell lymphoma and progressive systemic scleroderma II. The analysis of HETEs involved hydrogenation, solid phase extraction on a C18 cartridge, formation of pentafluorobenzyl bromide and trimethylsilyl ether derivatives. In the case of F2-isoprostanes, the analytical procedure was similar to that of HETEs except that the hydrogenation step was omitted. In the plasma of healthy volunteers picomole amounts of 2-, 5-, 8-12-, 15-HETEs, 8-iso-PGF(2alpha) and 9alpha,11alpha-PGF(2alpha) were quantified by using 12-hydroxy-heptadecatrienoic acid and PGF(2alpha)-d4 as internal standards of HETEs and isoprostanes, respectively. Analysis of plasma samples obtained from patients before and after extracorporeal photoimmunotherapy revealed characteristic increases in both, HETE and isoprostane levels. The enhancement of indicators of lipid peroxidation is in correspondence with a moderate loss of alpha-tocopherol, the most important lipid-soluble antioxidant in human plasma. Thus, our data confirm the involvement of lipid peroxidation in extracorporeal photoimmunotherapy.

Abstract
Cutaneous T-cell lymphoma (CTCL) is a lymphoproliferative skin disease with limited therapeutic options. Ten CTCL patients were treated with once-weekly intranodal injection of 1 x 106 mature monocyte-derived dendritic cells (DCs) pulsed with 100 microg/mL tumor lysate protein equivalent and keyhole limpet hemocyanin (50 microg/mL). Tumor-specific delayed-type hypersensitivity (DTH) reactions developed in 8 of 8 patients challenged with tumor-lysate-pulsed DCs and in 3 of 8 patients challenged with tumor lysate alone. Three of 5 patients showed significant tumor-lysate-specific increases of in vitro peripheral blood lymphocyte proliferation coinciding with increased interferon-alpha (IFN-alpha) production. Five of 10 (50%) patients had objective responses. Four patients had partial responses (PRs). Two are still in PR, and the other 2 patients had a mean PR duration of 10.5 months. One patient had a complete response (CR) for 19 months that is ongoing. The remaining 5 patients had progressive disease. In the 5 responder patients, 6.8 +/- 1.4 vaccinations were necessary to induce an objective clinical response. Response was associated with low tumor burden. Continuation of vaccinations with new tumor lysate derived from progressive lesions reinduced treatment responses in 2 patients in PR. Selected patients had massive infiltration of CD8+ and TIA+ cytotoxic T cells at the site of regressing lesions and molecular remission after therapy. Intranodal injection of autologous tumor-lysate-pulsed DCs is well-tolerated and achieves immunologic and objective clinical responses in selected CTCL patients.

Abstract
Extracorporeal photopheresis (ECP) has been shown to be clinically effective in the treatment of many T cell-mediated conditions. ECP's mechanism of action includes the induction of apoptosis and the release of pro-inflammatory cytokines. Recently, we have observed early lymphoid apoptosis, detectable immediately post ECP. We were interested to determine what influence ECP has on pro-inflammatory cytokine secretion at this early pre-infusion stage. Samples from 6 cutaneous T cell lymphoma (CTCL) and 5 graft versus host disease (GvHD) patients were taken pre ECP and immediately post ECP, prior to re-infusion. Following separation, the PBMCs were added to a cell culture medium and stimulated with PMA, Ionomycin, and Brefeldin A for 6 hours. Using flow cytometry, intracellular cytokine expression of IFNgamma and TNFalpha was determined in the T cell population. The monocytes were evaluated for IL6, IFNgamma, IL12, and TNFalpha. For both patient groups, the number of IFNgamma-expressing T cells fell significantly at re-infusion, whilst both T cell- and monocyte-expressing TNFalpha levels were reduced at re-infusion. All other cytokines tested showed no significant change post ECP. For GvHD, pro-inflammatory cytokines have a pathological role. Their down-regulation may have a direct clinical benefit. However, the reduction in the number of IFNgamma- and TNFalpha-expressing mononuclear cells means, at this early stage, it is unlikely that these cytokines assist in the removal of the malignant Th2 cells present in CTCL.

Abstract
This article refers to papulosquamous diseases that are seen in the elderly. Many of these diseases are complex to diagnose due to the fact that they are difficult to identify, because they may resemble a similar disorder, which can be misleading. The problem that is frequently seen with these diseases is that they are commonly misdiagnosed. In this article the authors include information that will help with identifying these diseases. The authors also provide important laboratory exams that can be performed and can help guide diagnosis, as well as differential diagnosis and treatment options.

Abstract
We report a case of an Epstein-Barr virus (EBV)-associated nasal-type natural killer cell lymphoma (NKCL) preceded by benign panniculitis, which arose in a 48-year-old woman with an asymptomatic human T-cell leukemia/lymphoma virus type-1 (HTLV-1) infection. A biopsy of the initial panniculitis lesion demonstrated lobular panniculitis with a germinal center composed of benign mononuclear cells with a phenotype of CD4+CD45RO+CD5sCD3+ cCD3 epsilon + T-cell intracellular antigen-1 (TIA-1)- and granzyme B-. One year after oral prednisolone therapy, the patient developed subcutaneous nodules composed of atypical lymphoid cells with a phenotype of CD4-CD45RO+CD56+sCD3-cCD3 epsilon + (TIA-1)+ and granzyme B+. In the initial panniculitis lesion, neither EBV-encoded RNA (EBER-1) nor clonal proliferation of EBV-infected cells was identified. In later lesions, however, a large number of atypical cells were positive for EBER-1, and a clonal expansion of EBV-infected cells was detected. No clonal rearrangement of T-cell receptor-alpha, -beta, or -gamma genes was found in either specimen. This patient was an asymptomatic carrier of human T-cell leukemia/lymphoma virus type-1 (HTLV-1) without clonal integration of proviral HTLV-1 in neither the peripheral blood nor the skin lesions. These observations suggest that EBV-associated NKCL occurred subsequently in the clinical course of benign panniculitis under the influence of immunosuppression caused by prednisolone treatment and HTLV-1 infection.

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
Cutaneous lymphomas include various types of clonal lymphoproliferative disorders. The adequate treatment approach depends on the exact diagnosis and should be non-aggressive in most cases. In early stages, local approaches such as UV or radiotherapy are preferred. In advanced stages, systemic drugs such as interferon-alpha or bexarotene can be administered. Experimental approaches for cutaneous lymphomas include vaccination and gene therapy.

Abstract
BACKGROUND The prognosis of patients with stage IV cutaneous T-cell lymphoma (CTCL) is grim and therapeutic options are limited. Treatment of advanced-stage CTCL is aimed at suppressing the dominant T-cell clone, which is typically present in the skin, peripheral blood, and lymph nodes. OBSERVATIONS We detected the expansion of 1 T-cell clone expressing the T-cell receptor V beta 14 in the peripheral blood of a patient with stage IVA CTCL. Before initiation of combination therapy with photopheresis and low-dose interferon alpha, the dominant T-cell clone represented 84% of the total T-cell population. After successful therapy, this clone showed a dramatic decrease to 6% of the T-cell population after 6 months of treatment. This reduction in the percentage of the malignant T-cell population in response to therapy was paralleled by clinical skin improvement from initial generalized erythroderma to undetectable skin disease. CONCLUSIONS This case demonstrates that response to combination treatment with photopheresis and low-dose interferon alpha in patients with advanced CTCL may be accurately and quantitatively followed up by monitoring the percentage of the malignant T-cell clone (when identifiable) within the total circulating T-cell population by flow cytometry.

Malignant neoplasm from natural killer (NK) cells are characterized by their positivity for CD56 and absence of monoclonal TCR gene rearrangement. We present the case of a 54-year-old man with a fungous mass in his left flank whose histological examination was consistent with cutaneous extranasal T/NK cell lymphoma. We review the literature and also discuss the prognosis and treatment of this variety of lymphoma.

Abstract
UNLABELLED Immediately following ECP, a significant number of lymphocytes become apoptotic and the number of T cells producing TNFalpha and IFNgamma is reduced. This study sought to determine if the cytokine down-regulation was a direct consequence of apoptosis induction. METHODS Samples were obtained from 6 graft versus host disease (GvHD) and 5 cutaneous T cell lymphoma (CTCL) patients immediately pre-ECP and from the leucocyte collection bag following 8-MOP/UVA exposure, but prior to re-infusion. Separated peripheral blood mononuclear cells (PBMC) were placed in cell culture and stimulated for 6 hours with phorbol myristate acetate (PMA), Ionomycin and Brefeldin A. Using flow cytometry, T cells were identified by CD3 expression and apoptotic T cells sub-selected by Annexin V staining. Both apoptotic and non-apoptotic T cells were evaluated for their intracellular expression of IL2, IL4, IL10, IFNgamma and TNFalpha. RESULTS Neither patient group demonstrated a significant change in IL4 or IL10 expression post ECP. However the number of T cells expressing IL2, IFNgamma and TNFalpha was reduced in both the Annexin V-positive and -negative T cell populations (P <.05). The nonapoptotic T cells from GvHD patients demonstrated the greatest reduction in cytokine expression. CONCLUSIONS Since proinflammatory cytokines play a major role in the pathology of GvHD, their down-regulation post-ECP may produce a direct clinical benefit. The lowest number of IL2-, IFNgamma- and TNFalpha-expressing T cells occurred within the apoptotic population; however, Annexin V-negative T cells also demonstrated a marked reduction post-ECP. However, the lack of an increase in IL4 and IL10 expression indicates that this process was not a consequence of skewing toward a Th2 cytokine profile.
