Abstract
Recent advances in cancer treatment have emerged from new immunotherapies targeting T-cell inhibitory receptors, including cytotoxic T-lymphocyte associated antigen (CTLA)-4 and programmed cell death (PD)-1. In this context, anti-CTLA-4 and anti-PD-1 monoclonal antibodies have demonstrated survival benefits in numerous cancers, including melanoma and non-small-cell lung carcinoma. PD-1-expressing CD8+ T lymphocytes appear to play a major role in the response to these immune checkpoint inhibitors (ICI). Cytotoxic T lymphocytes (CTL) eliminate malignant cells through recognition by the T-cell receptor (TCR) of specific antigenic peptides presented on the surface of cancer cells by major histocompatibility complex class I/beta-2-microglobulin complexes, and through killing of target cells, mainly by releasing the content of secretory lysosomes containing perforin and granzyme B. T-cell adhesion molecules and, in particular, lymphocyte-function-associated antigen-1 and CD103 integrins, and their cognate ligands, respectively, intercellular adhesion molecule 1 and E-cadherin, on target cells, are involved in strengthening the interaction between CTL and tumor cells. Tumor-specific CTL have been isolated from tumor-infiltrating lymphocytes and peripheral blood lymphocytes (PBL) of patients with varied cancers. TCRβ-chain gene usage indicated that CTL identified in vitro selectively expanded in vivo at the tumor site compared to autologous PBL. Moreover, functional studies indicated that these CTL mediate human leukocyte antigen class I-restricted cytotoxic activity toward autologous tumor cells. Several of them recognize truly tumor-specific antigens encoded by mutated genes, also known as neoantigens, which likely play a key role in antitumor CD8 T-cell immunity. Accordingly, it has been shown that the presence of T lymphocytes directed toward tumor neoantigens is associated with patient response to immunotherapies, including ICI, adoptive cell transfer, and dendritic cell-based vaccines. These tumor-specific mutation-derived antigens open up new perspectives for development of effective second-generation therapeutic cancer vaccines.

Abstract
The leukemias of mature B cells and T cells are a limited set of diseases in which blood and bone marrow are the primary sites of involvement. Although they may superficially resemble one another, they have distinct clinical and pathologic features and must be distinguished from one another. In this article, the major clinical, morphologic, phenotypic, and molecular genetic features of the mature B- and T-cell leukemias are reviewed, and differential diagnostic considerations are discussed.

Abstract
Identification of malignant Sézary cells by T-cell receptor (TCR) clonality studies is routinely used for the diagnosis of Sézary syndrome, but T-cell clones expressed in a single patient have never been accurately characterized. We previously reported that CD158k expression delineates Sézary syndrome malignant cells, and, more recently, we identified vimentin at the surface membranes of Sézary cells and normal activated lymphocytes. In the present study, T-cell clones from 13 patients with Sézary syndrome were identified by immunoscopy and further characterized in the blood according to their TCR Vbeta, CD158k, and vimentin cell-surface expression. We found in most patients a unique malignant T-cell clone that coexpressed CD158k and vimentin and that, when patients were tested, was also present in the skin. However, in some patients we detected the presence of a nonmalignant circulating clone expressing high amounts of vimentin and lacking CD158k. These results indicate that clonal expansion may originate from circulating malignant and nonmalignant CD4(+) T cell populations in patients with Sézary syndrome. Identification of the malignant cells in Sézary syndrome cannot be achieved by T-cell clonality studies or by TCR Vbeta monoclonal antibody (mAb) analysis alone; it also relies on CD158k phenotyping.

Abstract
Extracorporeal photopheresis is an accepted method for the treatment of cutaneous T-cell lymphoma and much progress has recently been achieved in therapy and understanding of its mechanism. In general large numbers of white blood cells are collected by a cell separator and irradiated in the presence of 8-MOP. In contrast to this practice, data from an animal model showed that as few as 0.2% of the body's blood volume irradiated are sufficient to achieve an immune response after photopheresis. Based on these data we developed a small-scale photopheresis procedure and applied the method in 3 end-stage T-cell lymphoma patients who were not eligible for apheresis. The mononuclear cells from 50 ml of blood were separated by density gradient centrifugation, irradiated with UV-light in the presence of 8-Methoxy-Psoralen (MOP) with 2J/cm(2) and reinjected. 2-3 treatments per week were conducted. The three patients-2 male and 1 female, age 63-86, Sezary syndrome (1x) and mycosis fungoides in tumour stage (2x)-showed no side effects on cell injection. The two patients with mycosis fungoides showed a prompt regression and softening of the tumours. The patient with Sezary syndrome developed numerous necrotic spots on the skin after 6 weeks of therapy that turned normal within a few days. Patient 1 died of pneumonia 4 weeks after the start of therapy and patient 3 died of heart failure 8 weeks after start of therapy, both during regression of the tumours. Patient 2 was treated over a period of 11 months, with an initial regression in the first weeks followed by a slow progression of the tumours after she rejected any form of further treatment. The small-scale extracorporeal photopheresis therapy presented is effective in cutaneous T-cell lymphoma. But questions regarding the optimal number of cells irradiated per treatment, the conditions of cell incubation after irradiation and the number of treatment cycles are still open. Therefore further studies are required to establish a method that is effective and circumvents the use of apheresis technology.

Abstract
Antibodies directed against the beta chain of the T cell receptor (anti-Vbeta antibodies) are useful to identify the Vbeta repertoire of T cells in various diseases and to quantify numbers of Vbeta-bearing T cells. The goals of this study were to identify Vbeta+ cases of leukemic phase cutaneous T cell lymphoma (CTCL) and to compare the percentage of positive calls with other measures of blood tumor burden, i.e., lymphocyte subsets with a CD4+CD7- and CD4+CD26- phenotype and Sezary cell counts. Thirty-three of 49 (67%) cases of leukemic CTCL reacted with an anti-Vbeta antibody. When combined with reports from the literature, the frequency of Vbeta5 (probably Vbeta5.1) usage was relatively high when compared with Vbeta2 that is also frequently expressed by normal CD4+ T cells. The percentage of Vbeta+ cells correlated to the percentage of CD4+CD7- and CD4+CD26- cells for cases in which the neoplastic cells were deficient in expression of CD7 and CD26, respectively, but not the Sezary cell count. We hypothesize that the increased Vbeta5.1 usage in CTCL may be the result of depletion of Vbeta2 and other Vbeta-bearing T cells by staphylococcal superantigens prior to neoplastic transformation, resulting in a relative increase in the frequency of Vbeta5.1 usage in CTCL.

Abstract
In this review, we have highlighted recent advances in chronic lymphoproliferative disorders that commonly involve the peripheral blood. As we have seen, our concepts of certain diseases are changing. Molecular genetic and immunophenotypic studies are allowing more precise characterization of CLL and defining important biologic markers that predict clinical behavior. Prolymphocytic leukemia is now more narrowly defined and its relationship to nucleolated variants of MCL is now apparent. With new reagents and techniques applied to problems such as identification of Sezary cells and T-cell monoclonality determination, our ability to diagnose, monitor, and provide prognostic information is improving. Insight into the biology of these diseases also may provide new therapeutic targets in the future.

Abstract
Primary cutaneous T- and B-cell lymphomas are a heterogenous group of diseases with varied clinical presentations and prognosis. The use of new molecular, histological, and clinical criteria have enhanced the recognition of primary cutaneous T- and B-cell lymphomas. Compared to their nodal counterpart they have a different clinical behavior and therefore require a different treatment approach. Independent predictive factors identified clinically, histologically, and by immunopheno- and immunogenotyping are essential to assess the appropriate treatment for each subtype. The European Organization for Research and Treatment of Cancer (EORTC) Cutaneous Lymphoma Study Group provide a classification of cutaneous lymphomas taking into account of the histological and molecular features. Based on this classification we will provide a summary of the current medical literature in diagnosis, treatment, and prognosis for primary cutaneous lymphomas with emphasis on new treatment strategies.

Abstract
Extracorporeal photochemotherapy (ECP) has been shown to be effective in variety of pathologic diseases such as Sezary syndrome, autoimmune diseases, organ graft rejection and graft versus host disease. However, its mechanism of action has remained elusive. Understanding of its mechanisms may be useful to identify the best indications, treatment regimes and to optimize the ECP technique. The first step of the ECP procedure is collection of peripheral mononuclear cells. In this step, several cell environment changes occur. These conditions have been suggested to increase monocyte activation and possibly drive dendritic cell differentiation. The second step of ECP is the cell radiation by UVA in presence of 8-MOP which is presumed to induce cell membrane damage, DNA crosslinking and binding to a variety of cytosolic proteins leading to apoptosis, modification of membrane antigenicity and antigen presenting cell activation. The third step of ECP is the reinfusion of the treated cells to the patient. While it is unclear what exactly occurs in vivo, it is thought that DCs play a critical role by inducing an immunological response against pathogenic cells. The immature DC, activated by ECP, phagocytizes and internalizes the apoptotic cells; processes the antigens and increases the synthesis of class I and II Major Histocompatibility Complex (MHC) molecules. The peptides associated with class II MHC are presented to the CD4+ T helper cells. The final maturation of DC is completed in vivo with the help of these activated T helper cells using a variety of mechanisms including CD40 ligation. Finally, the mature DCs fully loaded with pathogenic T cell peptides migrate to secondary lymphoid organs stimulate the naive CD8+ T cells and induce a cytotoxic response (Th1 immune response) directed against pathogenic clones (tumoral cells of Sezary syndrome). Clinical and haematological improvement after ECP in Sezary syndrome is associated with a shift in Th1/Th2 balance and the increase of Th1 cytokines and IL12. ECP can also down regulate the allo or autoimmune response and induces tolerance by regulatory T cells. The clinical response to ECP in patients with chronic GvHD is associated with increase in NK cells and a shift from DC1 to DC2 and a shift from predominantly Th1 to Th2 immune response. Recruitment and involvement of other immune cells in the mechanism of ECP have been suggested and merit more studies. This immunostimulatory capacity of ECP is the most probable hypothesis of its mechanism but further investigations are necessary to determine the precise players important for this activity.
