Cutaneous T-cell lymphoma (CTCL) is the most frequently encountered type of skin lymphoma in humans. CTCL encompasses multiple variants, but the most common types are mycosis fungoides (MF) and Sezary syndrome (SS). While most cases of MF run a mild course over a period of many years, other subtypes of CTCL are very aggressive. The rapidly expanding fields of proteomics and genomics have not only helped increase knowledge concerning the carcinogenesis and tumor biology of CTCL but also led to the discovery of novel markers for targeted therapy...

Bexarotene is approved for the treatment of cutaneous T cell lymphomas in patients refractory to at least one prior systemic therapy. Associated hypertriglyceridaemia requires monitoring, but can readily be managed with concomitant medication, such as fenofibrate. Here we report three cases of hypertriglyceridaemia secondary to bexarotene assumption, which was adequately managed with omega-3 fatty acids. If fenofibate-related side effects occur, or a statin is required to control low-density lipoprotein-cholesterol, omega-3 fatty acids should be considered as a good alternative therapy to lower lipid levels during bexarotene treatment...

Bexarotene is an oral retinoid shown to be active against the cutaneous manifestations of cutaneous T-cell lym-phoma (CTCL). Literature on the efficacy, dosing and side-effects of bexarotene is sparse. We present here data on 37 Finnish patients with CTCL treated with bexarotene during the last 10 years. Bexarotene was equally effective as monotherapy or when combined with other treatment modalities, resulting in overall responses of approximately 75%. Early-stage CTCL responded better than advanced-stage CTCL (83% vs...

Bexarotene is an oral retinoid therapy that is effective for the treatment of early and advanced-stage cutaneous T-cell lymphoma (CTCL) in patients who have failed on other therapies. However, bexarotene treatment is associated with unavoidable side-effects, in particular hypertriglyceridaemia and hypothyroidism, which are manageable with adequate concomitant medications and are reversible on cessation of treatment. A pragmatic strategy for minimizing bexarotene-associated hypertriglyceridaemia and hypothyroidism is suggested, based on data from the studies with bexarotene in CTCL and on day-to-day experience with this agent in the clinical setting...

BACKGROUND: The mechanisms of action of bexarotene are not well understood. METHODS: A retrospective study on patients with cutaneous T-cell lymphoma (CTCL) treated with bexarotene was performed to see if bexarotene could act on the dominant T-cell clones. Thirty-five patients were included. Twenty-three were treated with bexarotene for more than 3 months (300 mg/m(2)). In 7 patients, phototherapy was given with bexarotene. RESULTS: Dominant T-cell clones were observed in 11 patients in peripheral blood and in 19 patients in skin...

The retinoid X receptor (RXR) plays a critical role in transcriptional regulation via formation of an RXR homodimer or heterodimers with partner nuclear receptors. Despite the numerous beneficial effects, only a limited number of naturally occurring RXR agonists are known. In this report, two prenylated flavanones (1 and 2) isolated from Sophora tonkinensis were identified as new rexinoids that preferentially activated RXRs, relative to the retinoic acid receptor. The activities of 1 and 2 were the most potent among naturally occurring rexinoids, yet 2 orders of magnitude lower than the synthetic rexinoid bexarotene...

Cutaneous T-cell lymphoma (CTCL) are a heterogeneous group of lymphoproliferative disorders, characterized by the infiltration of the epidermis by mature and activated malignant CD4+ T-lymphocytes. Retinoids such as retinoic acid and synthetic analogues have long been used alone or in combination with other therapies for CTCL. Bexarotene, the first synthetic highly selective RXR retinoid, was approved for the treatment of all stages of CTCL in patients refractory to at least one systemic therapy. Recently, six cases in which the initiation of bexarotene therapy for CTCL was associated with the progression of internal disease despite improvement of cutaneous signs and symptoms were reported...

BACKGROUND: High response rates for doxorubicin HCl liposome injection (DLI) in cutaneous T-cell lymphoma (CTCL) have been reported with vague criteria until recently. Approximately 50% of CTCL patients respond to bexarotene (Bex). PATIENTS AND METHODS: A phase II trial was carried out to clarify the true overall response rate (ORR) for DLI and to assess the role of sequential Bex. Patients were treated with DLI 20 mg/m(2) i.v. every 2 weeks for 16 weeks (8 doses) followed by 16 weeks with Bex 300 mg/m(2) orally...

A 77-year-old white male presented to the clinic with two isolated cutaneous tumors on his forehead. A cutaneous biopsy showed a focally folliculotropic CD4 cutaneous lymphoma. The tumors were irradiated with a complete response, and he was started on oral bexarotene. He experienced localized cutaneous relapse 3 months into treatment. These new tumors now revealed a surprisingly CD8 cytotoxic phenotype, but with the same clone. A systemic workup was negative. His regimen was switched to romidepsin, and he was treated with local radiation again...

Safety, tolerability, pharmacokinetics and efficacy of bexarotene, a novel retinoid X receptor (RXR)-selective retinoid, were evaluated in Japanese patients with stage IIB-IVB and relapsed/refractory stage IB-IIA cutaneous T-cell lymphomas (CTCL). This study was conducted as a multicenter, open-label, historically controlled, single-arm phase I/II study. Bexarotene was p.o. administrated once daily at a dose of 300 mg/m(2) for 24 weeks in 13 patients, following an evaluation of safety and tolerability for 4 weeks at a dose of 150 mg/m(2) in three patients...

Peripheral T-cell lymphomas (PTCLs) are a heterogeneous group of aggressive non-Hodgkin lymphomas. Angioimmunoblastic T-cell lymphoma (AITL) is a common subtype of PTCL, and patients with AITL typically have a poor prognosis with limited treatment options. Clinical studies have demonstrated the activity of romidepsin, a structurally unique, potent, bicyclic class 1 selective histone deacetylase inhibitor, in patients with relapsed or refractory AITL. In the case presented herein, we describe a patient treated with single-agent romidepsin at first diagnosis of AITL, resulting in complete remission for over 2 years and leading to the use of maintenance dosing...

BACKGROUND: Ultraviolet light (UVL) is a long established treatment for mycosis fungoides (MF) and Sézary syndrome (SS), subtypes of cutaneous T-cell lymphoma (CTCL). Treatments have traditionally included broadband, narrowband ultraviolet B light (UVB) and psoralen plus ultraviolet A light photochemotherapy (PUVA), but more recently, treatment options have expanded to include UVA1 and excimer laser. UVL is used either as monotherapy or as an adjuvant to systemic therapy, demonstrating efficacy in many cases that equal or surpass systemic medications...

Cutaneous T-cell lymphoma (CTCL) is a rare disease occurring in Europe among two persons per million per year. It affects men more often than women (2:1). It is primarily a skin disease. In about 20% of patients, it becomes fatal with tumours in the skin and spreading to lymph glands. Approximately 3% of patients show a leukemic form called Sezary's syndrome, where malignant cells are present in blood with accompanying erythrodermia. CTCL is a T-lymphocyte disease occurring late in life as the average age of patients is around 66 years in Europe, Japan and the US...

Mycosis fungoides (MF) is the most common primary cutaneous T-cell lymphoma variant and is closely related to a rare leukemic variant, Sézary syndrome (SS). MF patients at risk of disease progression can now be identified and an international consortium has been established to address the prognostic relevance of specific biologic factors and define a prognostic index. There are a lack of randomized clinical trial data in MF/SS and evidence is based on a traditional "stage-based" approach; treatment of early-stage disease (IA-IIA) involves skin directed therapies which include topical corticosteroids, phototherapy (psoralen with UVA or UVB), topical chemotherapy, topical bexarotene, and radiotherapy including total skin electron beam therapy...

We genetically characterized seven nearly complete genomes in the protoparvovirus genus from the feces of children with diarrhea. The viruses, provisionally named cutaviruses (CutaV), varied by 1-6% nucleotides and shared ~76% and ~82% amino acid identity with the NS1 and VP1 of human bufaviruses, their closest relatives. Using PCR, cutavirus DNA was found in 1.6% (4/245) and 1% (1/100) of diarrhea samples from Brazil and Botswana respectively. In silico analysis of pre-existing metagenomics datasets then revealed closely related parvovirus genomes in skin biopsies from patients with epidermotropic cutaneous T-cell lymphoma (CTCL or mycosis fungoides)...

Cutaneous T-cell Lymphoma (CTCL) is a rare non-Hodgkin's lymphoma that can affect the skin, blood, and lymph nodes, and can metastasize at late stages. Novel therapies that target all affected disease compartments and provide longer lasting responses while being safe are needed. One potential therapeutic target is NF-κB, a regulator of immune responses and an important participant in carcinogenesis and cancer progression. As a transcription factor, NF-κB targets genes that promote cell proliferation and survival...
