Topical immunotherapy combo effective against early skin cancer

Researchers from the Washington University School of Medicine and Harvard Medical School have shown that a combination of 2 topical drugs can trigger an immune response against precancerous skin lesions. The study was published yesterday in The Journal of Clinical Investigation. The 2 drugs, calcipotriol and 5-fluorouracil, have been in use for years – topical 5-fluorouracil is prescribed to treat actinic keratosis. Calcipotriol is indicated by the FDA for psoriasis, an autoimmune disorder that presents with red, scaly patches of skin. The researchers combined the 2 drugs and evaluated the combination’s efficacy against actinic keratosis, a precursor to squamous cell carcinoma.

CONCLUSION: Due to its unclear components, potential toxicities, misuse, and over-application, TCM might contribute to tumorigenesis and progression of head neck carcinoma. We seek effective approaches to ensure the safe use of TCM. PMID: 31424693 [PubMed - in process]

This study aimed to explore novel biomarkers for GBM prognosis prediction. The gene expression profiles from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets of GBM were downloaded. A total of 2241 overlapping differentially expressed genes (DEGs) were identified from TCGA and GSE7696 datasets. By univariate COX regression survival analysis, 292 survival-related genes were found among these DEGs (p

Discussion MDSCs violently emerge in pathological conditions in an attempt to limit potentially harmful immune and inflammatory responses. Mechanisms supporting their expansion and survival are deeply investigated in cancer, in the perspective to reactivate specific antitumor responses and prevent their contribution to disease evolution. These findings will likely contribute to improve the targeting of MDSCs in anticancer immunotherapies, either alone or in combination with immune checkpoint inhibitors. New evidence indicates that the expansion of myeloid cell differentiation in pathology is subject to fine-tuning, as its...

Conclusion Analysis of the pleiotropic effects of IL-33 on multiple immunological cells (macrophages, mastocytes), as well as neurological cells of medulla oblongata, dorsal root ganglion, antigen-induced arthritis system, carrageen, and formalin, shows that this alarmin plays curtail, yet not fully known role in mediating inflammation, especially in chronic inflammatory pulmonary diseases such as asthma, COPD, and OSA. Taken into consideration the engagement in this process, in particular of mastocytes and their secretion of CXCL2, 4, 8, and other cytokines, there is no doubt regarding the etiopathogenic role of IL-33 in...

Discussion Suppressor of cytokine signaling 1 is an essential molecule for maintaining immune homeostasis and subverting inflammation. Disorders arising from excess inflammation or SOCS1 deficiency can be potentially treated with SOCS1 mimetics (Ahmed et al., 2015). While SOCS1 has promising potential in many disorders, it should be noted that new targets and actions of SOCS1 are still being discovered and not all the effects of this protein are beneficial in autoimmune diseases and cancer. For instance, SOCS1 degrades IRS1 and IRS2, required for insulin signaling, via the SOCS Box domain, thus, limiting its potential in ...

Erica S. Tarabadkar† and Michi M. Shinohara*† Division of Dermatology, University of Washington, Seattle, WA, United States Skin directed therapies (SDTs) serve important roles in the treatment of early stage cutaneous T-cell lymphoma (CTCL)/mycosis fungoides (MF), as well as managing symptoms and improving quality of life of all stages. There are now numerous options for topical therapies that demonstrate high response rates, particularly in early/limited MF. Phototherapy retains an important role in treating MF, with increasing data supporting efficacy and long-term safety of both UVB and PUVA as ...

Authors: Rahkola D, Laitala J, Siiskonen H, Pelkonen J, Harvima IT Abstract By using immunohistochemistry and antibodies that identify complement C3c (in C3 and C3b) or CD11b receptor, we report that the proportion C3c+ mast cells and the number of CD11b+ cells are increased in basal cell carcinoma (BCC). Instead, only CD11b+ cells are increased in squamous cell carcinoma/Bowen's disease, and only slightly so in actinic keratosis. Only C3c+ mast cells are increased in psoriasis. Furthermore, C3c+ mast cells correlated positively with CD11b+ cells, and iC3b immunoreactivity was detected around tryptase+ mast cells. ...

We describe a 68-year-old female who presented to the dermatology office with a previous history of over 30 BCCs that had been previously biopsied and/or surgically removed. However, the patient had been lost to follow up for several years and had not been seen by a skin specialist. In the interim, she had been misdiagnosed as having eczematous or psoriatic lesions by primary care providers. Patients with Gorlin syndrome are even harder to diagnose as their skin cancers often do not possess the classic features associated with a basal cell or squamous cell carcinoma. When in doubt, and especially if failing topical therapy...
