Review
Cutaneous T-cell lymphomas are a heterogeneous collection of non-Hodgkin lymphomas that arise from skin-tropic memory T lymphocytes. Among them, mycosis fungoides (MF) and Sézary syndrome (SS) are the most common malignancies. Diagnosis requires the combination of clinical, pathologic, and molecular features. Significant advances have been made in understanding the genetic and epigenetic aberrations in SS and to some extent in MF. Several prognostic factors have been identified. The goal of treatment is to minimize morbidity and limit disease progression. However, hematopoietic stem cell transplantation, considered for patients with advanced stages, is the only therapy with curative intent.

Review
While most patients with early-stage mycosis fungoides (MF) follow an indolent course, patients with advanced-stage MF/Sézary syndrome (SS) have a poor prognosis with a median survival of less than 5 years. Although there are a number of treatments currently available, achieving and maintaining a durable response remain challenging, especially in advanced-stage MF/SS. The choice of frontline therapy is dependent on the stage of disease. For early-stage MF, the treatment concept is to control skin lesions mainly by skin-directed therapies, such as topical therapies, phototherapies, and radiotherapies. For advanced-stage MF/SS, systemic treatments by biological or targeted therapies including bexarotene and interferon either alone or in combination are tried first, with more immunosuppressive chemotherapies being reserved for refractory or rapidly progressive disease. Recent improvements in biological or targeted therapies include brentuximab vedotin and mogamulizumab. When biopsy samples have 10% or more CD30-positive malignant cells, brentuximab vedotin, an anti-CD30 antibody conjugated to monomethyl auristin E, can be a desirable treatment option. For cases with blood involvement, mogamulizumab, an antibody binding to C-C chemokine receptor 4, is effective with high response rates. In the refractory setting, alemtuzumab, histone deacetylase inhibitors, pralatrexate, gemcitabine, and doxorubicin are considered as the treatment option. Because only allogeneic hematopoietic stem cell transplantation can offer a chance of cure with durable complete remission, advanced-stage patients with a markedly short life expectancy should be evaluated for eligibility. Given that there are few randomized controlled studies in the literature, it is necessary to investigate which therapy is preferable for each patient with MF/SS by comparative prospective trials.

Comparative Study Randomized Controlled Trial
BACKGROUND
Cutaneous T-cell lymphomas are rare non-Hodgkin lymphomas with substantial morbidity and mortality in advanced disease stages. We compared the efficacy of mogamulizumab, a novel monoclonal antibody directed against C-C chemokine receptor 4, with vorinostat in patients with previously treated cutaneous T-cell lymphoma.
METHODS
In this open-label, international, phase 3, randomised controlled trial, we recruited patients with relapsed or refractory mycosis fungoides or Sézary syndrome at 61 medical centres in the USA, Denmark, France, Italy, Germany, the Netherlands, Spain, Switzerland, the UK, Japan, and Australia. Eligible patients were aged at least 18 years (in Japan, ≥20 years), had failed (for progression or toxicity as assessed by the principal investigator) at least one previous systemic therapy, and had an Eastern Cooperative Oncology Group performance score of 1 or less and adequate haematological, hepatic, and renal function. Patients were randomly assigned (1:1) using an interactive voice web response system to mogamulizumab (1·0 mg/kg intravenously on a weekly basis for the first 28-day cycle, then on days 1 and 15 of subsequent cycles) or vorinostat (400 mg daily). Stratification was by cutaneous T-cell lymphoma subtype (mycosis fungoides vs Sézary syndrome) and disease stage (IB-II vs III-IV). Since this study was open label, patients and investigators were not masked to treatment assignment. The primary endpoint was progression-free survival by investigator assessment in the intention-to-treat population. Patients who received one or more doses of study drug were included in the safety analyses. This study is ongoing, and enrolment is complete. This trial was registered with ClinicalTrials.gov, number NCT01728805.
FINDINGS
Between Dec 12, 2012, and Jan 29, 2016, 372 eligible patients were randomly assigned to receive mogamulizumab (n=186) or vorinostat (n=186), comprising the intention-to-treat population. Two patients randomly assigned to mogamulizumab withdrew consent before receiving study treatment; thus, 370 patients were included in the safety population. Mogamulizumab therapy resulted in superior investigator-assessed progression-free survival compared with vorinostat therapy (median 7·7 months [95% CI 5·7-10·3] in the mogamulizumab group vs 3·1 months [2·9-4·1] in the vorinostat group; hazard ratio 0·53, 95% CI 0·41-0·69; stratified log-rank p<0·0001). Grade 3-4 adverse events of any cause were reported in 75 (41%) of 184 patients in the mogamulizumab group and 76 (41%) of 186 patients in the vorinostat group. The most common serious adverse events of any cause were pyrexia in eight (4%) patients and cellulitis in five (3%) patients in the mogamulizumab group; and cellulitis in six (3%) patients, pulmonary embolism in six (3%) patients, and sepsis in five (3%) patients in the vorinostat group. Two (67%) of three on-treatment deaths with mogamulizumab (due to sepsis and polymyositis) and three (33%) of nine on-treatment deaths with vorinostat (two due to pulmonary embolism and one due to bronchopneumonia) were considered treatment-related.
INTERPRETATION
Mogamulizumab significantly prolonged progression-free survival compared with vorinostat, and could provide a new, effective treatment for patients with mycosis fungoides and, importantly, for Sézary syndrome, a subtype that represents a major therapeutic challenge in cutaneous T-cell lymphoma.

DISEASE OVERVIEW
Cutaneous T-cell lymphomas (CTCL) are a heterogenous group of T-cell neoplasms involving the skin, the majority of which may be classified as Mycosis fungoides (MF) or Sézary syndrome (SS).
DIAGNOSIS
The diagnosis of MF or SS requires the integration of clinical and histopathologic data.
RISK-ADAPTED THERAPY
TNMB (tumor, node, metastasis, blood) staging remains the most important prognostic factor in MF/SS and forms the basis for a "risk-adapted," multi-disciplinary approach to treatment. For patients with disease limited to the skin, skin-directed therapies are preferred, as both disease-specific and overall survival for these patients is favorable. In contrast, patients with advanced-stage disease with significant nodal, visceral or blood involvement are generally approached with systemic therapies. These include biologic-response modifiers, histone deacetylase (HDAC) inhibitors, or antibody-based strategies, in an escalating fashion. In highly-selected patients, allogeneic stem-cell transplantation may be considered, as this may be curative in some patients.

Review
Cutaneous T-cell lymphoma is a rare type of extranodal non-Hodgkin's lymphoma that primarily affects the skin. The uncertain pathogenesis and variable clinical presentation make the diagnosis and management of cutaneous T-cell lymphoma a challenge. Cutaneous T-cell lymphoma is a chronic, relapsing illness with treatment aimed at symptomatic relief and improving patient related quality of life. Early-stage cutaneous T-cell lymphoma typically follows an indolent course, often being mistaken for benign dermatological conditions which can lead to a diagnostic delay. Advanced stage cutaneous T-cell lymphoma has a poor prognosis with significant morbidity. Accurate diagnosis and early involvement of a specialist team is paramount to ensure correct management and improved patient outcomes. Promising advances are being made to develop novel agents which could improve prognosis and quality of life. This article provides an overview of the two main subtypes of cutaneous T-cell lymphoma: mycosis fungoides and Sézary syndrome. Clinical presentation, histopathological correlation and diagnostic challenges are reviewed alongside example case studies.

Review
On behalf of the EORTC Cutaneous Lymphoma Tumours Group (EORTC-CLTG) and following up on earlier versions published in 2006 and 2017 this document provides an updated standard for the treatment of mycosis fungoides and Sézary syndrome (MF/SS). It considers recent relevant publications and treatment options introduced into clinical practice after 2017. Consensus was established among the authors through a series of consecutive consultations in writing and a round of discussion. Treatment options are assigned to each disease stage and, whenever possible and clinically useful, separated into first- and second line options annotated with levels of evidence. Major changes to the previous version include the incorporation of chlormethine, brentuximab vedotin, and mogamulizumab, recommendations on the use of pegylated interferon α (after withdrawal of recombinant unpegylated interferons), and the addition of paragraphs on supportive therapy and on the care of older patients. Still, skin-directed therapies are the most appropriate option for early-stage MF and most patients have a normal life expectancy but may suffer morbidity and impaired quality of life. In advanced disease treatment options have expanded recently. Most patients receive multiple consecutive therapies with treatments often having a relatively short duration of response. For those patients prognosis is still poor and only for a highly selected subset long term remission can be achieved with allogeneic stem cell transplantation. Understanding of the disease, its epidemiology and clinical course, and its most appropriate management are gradually advancing, and there is well-founded hope that this will lead to further improvements in the care of patients with MF/SS.

Review
Primary cutaneous T-cell lymphomas (CTCLs) are defined as lymphomas with a T-cell phenotype that present in the skin without evidence of systemic or extracutaneous disease at initial presentation. CTCLs other than mycosis fungoides and Sézary syndrome (SS) account for approximately one third of CTCLs and encompass a heterogenous group of non-Hodgkin lymphomas, ranging from indolent lymphoproliferative disorders to aggressive malignancies with a poor prognosis. The spectrum of CTCLs continues to broaden as new provisional entities are classified. Given the morphologic and histologic overlap among CTCLs and other diagnoses, a thorough clinical history, physical evaluation, and clinicopathologic correlation are essential in the work up and diagnosis of these rare entities. This article will summarize the epidemiologic, clinical, pathologic, and diagnostic features of CTCLs other than mycosis fungoides and SS.

Review
In order to provide a common standard for the treatment of mycosis fungoides (MF) and Sézary syndrome (SS), the European Organisation for Research and Treatment of Cancer-Cutaneous Lymphoma Task Force (EORTC-CLTF) published in 2006 its consensus recommendations for the stage-adapted selection of management options for these neoplasms. Since then, the understanding of the pathophysiology and epidemiology of MF/SS has advanced, the staging system has been revised, new outcome data have been published and novel treatment options have been introduced. The purpose of the present document is to update the original recommendations bearing in mind that there are still only a limited number of controlled studies to support treatment decisions for MF/SS and that often treatment is determined by institutional experience and availability. This consensus on treatment recommendations was established among the authors through a series of consecutive consultations in writing and a round of discussion. Recommended treatment options are presented according to disease stage, whenever possible categorised into first- and second-line options and supported with levels of evidence as devised by the Oxford Centre for Evidence-Based Medicine (OCEBM). Skin-directed therapies are still the most appropriate option for early-stage MF, and most patients can look forward to a normal life expectancy. For patients with advanced disease, prognosis is still grim, and only for a highly selected subset of patients, prolonged survival can be achieved with allogeneic stem cell transplantation (alloSCT). There is a high need for the development and investigation in controlled clinical trials of treatment options that are based on our increasing understanding of the molecular pathology of MF/SS.
