Potential therapeutic uses of rexinoids.

Adv Pharmacol 2021 4;91:141-183. Epub 2021 Mar 4.

Department of Pharmacology & Toxicology, Michigan State University, East Lansing, MI, United States. Electronic address:

The discovery of nuclear receptors, particularly retinoid X receptors (RXR), and their involvement in numerous pathways related to development sparked interest in their immunomodulatory properties. Genetic models using deletion or overexpression of RXR and the subsequent development of several small molecules that are agonists or antagonists of this receptor support a promising therapeutic role for these receptors in immunology. Bexarotene was approved in 1999 for the treatment of cutaneous T cell lymphoma. Read More

Secondary Gamma-Delta T-Cell Lymphoma Not Otherwise Specified (NOS) From Chronic Immunosuppression.

Cureus 2021 May 2;13(5):e14808. Epub 2021 May 2.

Division of Hematology and Oncology, University of Florida, Gainesville, USA.

Herein, we present the case of a 63-year-old female with a history of Behçet's disease managed with long-term prednisone and azathioprine who initially presented for symptomatic anemia, which progressed to pancytopenia with neutropenic fever. Initial workup ruled out infectious etiologies but was indeterminate for immune-mediated or neoplastic causes. Bone marrow biopsy demonstrated a CD8+ gamma-delta T-cell neoplasm; however, imaging and skin biopsy pathology did not support hepatosplenic or cutaneous lymphoma involvement. Read More

83JAK-STAT inhibition mediates romidepsin and mechlorethamine synergism in Cutaneous T-cell Lymphoma.

J Invest Dermatol 2021 Jun 2. Epub 2021 Jun 2.

Institute for Cancer Genetics, Columbia University, New York, NY, USA; Department of Pathology and Cell Biology, Columbia University Irving Medical Center, New York, NY, USA. Electronic address:

Sézary Syndrome (SS) is an aggressive and disseminated form of Cutaneous T-cell lymphoma (CTCL) associated with dismal prognosis in which the histone deacetylase inhibitor romidepsin, has shown remarkable activity as a single agent. However, clinical responses to romidepsin are typically transient, highlighting the need for more effective therapies. Here, we show synergistic anti-lymphoma effects of romidepsin in combination with mechlorethamine, an alkylating agent, in CTCL cell lines and primary samples with strong antitumor effects in an in vivo model of SS.

Repurposing Infectious Diseases Vaccines Against Cancer.

Front Oncol 2021 13;11:688755. Epub 2021 May 13.

The Anticancer Fund, Strombeek-Bever, Belgium.

Vaccines used to prevent infections have long been known to stimulate immune responses to cancer as illustrated by the approval of the Bacillus Calmette-Guérin (BCG) vaccine to treat bladder cancer since the 1970s. The recent approval of immunotherapies has rejuvenated this research area with reports of anti-tumor responses with existing infectious diseases vaccines used as such, either alone or in combination with immune checkpoint inhibitors. Here, we have reviewed and summarized research activities using approved vaccines to treat cancer. Read More

Hematology Clinic Division, Faculty of Medicine, Hospital das Clínicas, Universidade de São Paulo, São Paulo, SP, Brazil.

Cutaneous T-cell lymphomas are a heterogeneous group of lymphoproliferative disorders, characterized by infiltration of the skin by mature malignant T cells. Mycosis fungoides is the most common form of cutaneous T-cell lymphoma, accounting for more than 60% of cases. Mycosis fungoides in the early-stage is generally an indolent disease, progressing slowly from some patches or plaques to more widespread skin involvement. Read More

Transformation of Lymphomatoid Papulosis Type D to CD8-Positive Aggressive Epidermotropic Cytotoxic T-Cell Lymphoma.

Histopathology 2021 May 29. Epub 2021 May 29.

Department of Pathology and Laboratory Medicine, The University of Calgary, Calgary, Alberta, Canada.

Primary cutaneous CD8-positive aggressive epidermotropic cytotoxic T-cell lymphoma (PCAECyTCL), historically described as Berti's lymphoma, is a rare entity with a rapid and usually fatal clinical course. While the clinicopathologic features are typically characteristic in their aggressiveness, this entity shares some histomorphologic overlap with lymphomatoid papulosis (LyP) type D, a more indolent disease. We report an intriguing case of presumed transformation of an initially indolent LyP into an aggressive PCAECyTCL. Read More

Serum and cutaneous transcriptional expression levels of IL31 are minimal in cutaneous T cell lymphoma variants.

Biochem Biophys Rep 2021 Jul 4;26:101007. Epub 2021 May 4.

Department of Dermatology, Leiden University Medical Center, the Netherlands.

Aim: Recent studies suggested a role for IL31 in the pathogenesis of pruritus and disease severity in patients with cutaneous T cell lymphomas (CTCL). However, discrepant results were reported for IL31 serum levels, transcriptional expression levels or immunohistochemistry studies and its relation to pruritus intensity and/or disease severity in CTCL. Most studies did not distinguish between different CTCL variants. Read More

Department of Dermatology and Venerology, Aviation General Hospital, Beijing 100012, P.R. China.

Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma. The majority of patients with advanced stage MF are resistant to conventional chemotherapy and thus have a poor prognosis. The transcriptional repressor growth factor independence-1 (GFI-1) serves an important role in the development of T-cells. Read More
