An overview of cutaneous T cell lymphomas

Abstract: Cutaneous T cell lymphomas (CTCLs) are a heterogeneous group of extranodal non-Hodgkin’s lymphomas that are characterized by a cutaneous infiltration of malignant monoclonal T lymphocytes. They typically afflict adults with a median age of 55 to 60 years, and the annual incidence is about 0.5 per 100,000. Mycosis fungoides, Sézary syndrome, and primary cutaneous peripheral T cell lymphomas not otherwise specified are the most important subtypes of CTCL. CTCL is a complicated concept in terms of etiopathogenesi… Show more

“…Especially in the early stages, lesions can have variable clinical appearances and are often misdiagnosed as benign skin conditions like drug reactions, psoriasis, pityriasis, or forms of dermatitis or eczema [13].…”

“…While repression of gene transcription by deacetylating histones has been identified as the main epigenetic effect of HDAC inhibitors (HDACIs), it is only 1 of many processes that are being influenced. Multiple mechanisms of action, including induction of apoptosis and cell differentiation genes, acetylation of proteins regulating cell growth and survival, angiogenesis and DNA repair, and mitochondrial damage have not only been observed in T-cell lines and in primary T-cell lymphoma [4,13,56]. Besides these cellular mechanisms, there is evolving evidence that modulation of the tumor microenvironment may be important for the clinical effect: Induction of reactive oxygen species (ROS) [56,57] and antigen expression [58] as well as striking modulation of the cytokine profile with downregulation of immunosuppressive IL-10 have been demonstrated and may cause extensive changes in the microenvironment [59].…”

“…Insbesondere in den frühen Stadien können die Läsionen ganz unterschiedliche klinische Erscheinungsbilder zeigen und werden oft als benigne Hauterkrankungen fehldiagnostiziert (z.B. Arzneimittelreaktion, Psoriasis, Pityriasis, Dermatitis- oder Ekzemart) [13]. Da die CTCL eine besonders seltene und heterogene Gruppe von Erkrankungen sind, ist es erst kürzlich gelungen, zuverlässige prognostische Faktoren zu definieren.…”

“…Die Repression der Gentranskription durch die Deacetylatierung von Histonen wurde als epigenetischer Haupteffekt von HDAC-Inhibitoren (HDACI) identifiziert, ist allerdings nur einer von vielen Prozessen, in die die Wirkstoffe eingreifen. Zahlreiche Wirkmechanismen von der Induktion von Apoptose- und Zelldifferenzierungsgenen über die Acetylierung von Proteine, die das Zellwachstum und -überleben, die Angiogenese und DNA-Reparatur regulieren, bis hin zur Schädigung der Mitochondrien sind unter anderem bei T-Zelllinien und beim primären T-Zell-Lymphom beobachtet worden [4,13,56]. Neben diesen zellulären Mechanismen gibt es zunehmend auch Belege dafür, dass die Modulation der Tumormikroumgebung für die klinische Wirkung von Bedeutung sein könnte: Sowohl eine Induktion reaktiver Sauerstoffspezies (ROS) [56,57] und Antigenexpression [58] als auch eine ausgeprägte Modulation des Zytokinprofils (u.a.…”

“…Therefore, the aim of this work is to systematize the knowledge about the discovery step by comparing the approaches applied in three different software programs (GraphPadPrism, CompuSyn and MAPLE) in order to find the best-evaluated values of IC50 and m. In our recent study the effects of the natural product curcumin and the synthetic drugs from the group of anticancer alkylphosphocholines (APC) on cell lines from cutaneous T-cell lymphoma (CTCL) were of particular interest. CTCL is a rare extranodal T-cell lymphoproliferative disorder (non-Hodgkin's lymphoma), which primarily affects the skin by clonal accumulation of neoplastic T-lymphocytes [1,2,26]. Most of the patients have poor prognosis and overall survival up to 5 years or less [29].…”
