The cell surface molecules present on malignant cells are also expressed on normal CD4 T cells. Therefore, we attempted to find a specific marker for malignant cells that would distinguish them from normal cells. Comprehensive micr...

This article provides practical guidelines for the design and implementation of a phototherapy protocol for early stage MF, including an overview of treatment phases, response criteria, and considerations in the selection of a light source. Several evolving topics in phototherapy research are also discussed, including the relative efficacy of PUVA versus NBUVB, the role of maintenance therapy, risk of photocarcinogenicity, and combination therapies.

Abstract Mycosis fungoides and Sézary syndrome belong to the group of primary cutaneous T-cell lymphomas. Because of the inflammatory appearance of the skin lesions, we hypothesized that antimicrobial peptides might be dysregulated in these conditions, similar to in inflammatory skin conditions. Samples from 20 patients with cutaneous T-cell lymphoma were analysed using immunohistochemistry and enzyme-linked immunoassay (ELISA) of skin washing fluids of hBD-2, hBD-3, RNase 7 and psoriasin. Immunohistochemistry results were compared with previous analyses of healthy and psoriatic skin. ELISA and immunohistoc...

In conclusion, cdTSE has a limited role in SS. TTNT is reduced in heavily pre-treated MF patients, suggesting greater benefit when utilized earlier in treatment sequencing.

AbstractPurposeCutaneous T cell lymphomas (CTCL) are rare and histologically diverse lymphoproliferative neoplasms, with mycosis fungoides (MF) representing the most common disease subset. Given the emerging role of myeloid-derived suppressor cells (MDSC) as a clinically applicable biomarker in solid tumors, we sought to investigate the presence of tumor-infiltrating and circulating MDSC in early- and advanced-stage MF patients and evaluate their prognostic significance in patient overall survival.MethodsTumor-infiltrating MDSC were assessed immunohistochemically with Arginase-1 in 31 MF and 14 non-MF skin punch biopsies. ...

CONCLUSIONS: The clinical roles of PD-1/PD-L1 expression vary between subtypes of lymphoma. Future studies should delineate the prognostic and predictive roles of PD-1 and PD-L1 expression. PMID: 31704289 [PubMed - as supplied by publisher]

The PI3K/AKT/mTOR pathway is hyperactivated in many tumors, as well as in cutaneous T-cell lymphoma (CTCL) which includes mycosis fungoides (MF) and the aggressive variant known as Sezary syndrome (SS). TORC1 signaling is activated in SS cells by cytokines and chemokines, which are overexpressed in SS tissues. Furthermore, the recurrent copy number variation (CNV) of genes belonging to this cascade, such as PTEN, LKB1, and P70S6K, contributes to the hyperactivation of the pathway. The aim of this study was to investigate the therapeutic potential of mTOR inhibitors in CTCL.

AbstractCutaneous T cell lymphoma (CTCL) is a rare but potentially devastating primary cutaneous lymphoma. CTCL is characterized by localization of neoplastic T lymphocytes to the skin, with mycosis fungoides (MF) and its leukemic form, S ézary syndrome (SS) being the most common variants. Thymocyte selection-associated high-mobility group box (TOX) gene has been found to be highly expressed in MF and SS. It is reported that higher expression levels of TOX in patients will increase risks of disease progression and poor prognosis. Ho wever, the molecular events leading to these abnormalities have not been well unders...

Abstract Most patients with mycosis fungoides are diagnosed with early-stage disease. However, prevalence of early-stage disease is unknown, and evidence of its burden is scarce. The aim of this study is to estimate the prevalence of early-stage mycosis fungoides, how long patients live with early-stage disease and to characterise these patients. Data were obtained from 4 key publications and from US cancer registries (Surveillance, Epidemiology and End Results Program; SEER). The derived incidence of early-stage mycosis fungoides was 0.26/100,000 (UK), 0.29/100,000 (US) and 0.38/100,000 (US-SEER) and the prevalen...
