Treatment of malignant melanoma with coxsackievirus A21 (V937): An emerging oncolytic virotherapy.

Despite rising melanoma incidence in recent decades, there is a trend towards overall decreased mortality, reflecting multiple factors including improved treatment options for metastatic disease. While local treatments are the mainstay for early-stage melanoma, metastatic disease necessitates systemic treatment, with oncolytic virotherapy emerging as a promising option. For this review, articles were retrieved from PubMed from 1964 through 2024. We conducted title, abstract and full-text screening in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify articles describing the use of coxsackievirus A21 (V937), either as monotherapy or as part of combination therapy for malignant melanoma. Fifteen articles met inclusion criteria, offering preclinical and clinical data on V937's efficacy in reducing tumour burden. In addition to reporting manageable safety profiles, clinical trial data examining intratumoral V937 combination therapy with pembrolizumab and ipilimumab also endorsed favourable objective response rates compared to immune checkpoint inhibitor monotherapy (47% vs. 38% and 21% vs. 10%, respectively). In contrast, intravenous V937 monotherapy failed to yield additional benefit in a cohort of patients with Stage IIIC/IV melanoma (n = 3) despite achieving detectable levels in tumour tissue (1 × 109 TCID50). Although small subsets of patients experienced severe adverse effects and study design limitations imposed constraints on collected data, evidence for the efficacy of V937 remains encouraging. With few clinical trials evaluating V937 in melanoma, additional data is required before routine usage in standard treatment for metastatic lesions.

The Impact of the Recent Supreme Court Ruling on the Dermatology Recruitment Pipeline.

The 2023 ruling by the Supreme Court of the United States (SCOTUS) on the use of race-based criteria in college admissions may have implications for the selection of individuals into the dermatology workforce. This article highlights the impact of these decisions at the undergraduate, medical school, and graduate medical education levels, as well as within the field of dermatology.

Antibody-drug conjugates: A review of cutaneous adverse effects.

Antibody-drug conjugates (ADCs) are an emerging class of anticancer agents that combine targeting antibodies with potent cytotoxic agents. Their molecular configuration allows for increased therapeutic efficacy and reduced adverse-effect profiles compared to monoclonal antibodies or cytotoxic chemotherapy alone. ADCs cause off-target toxicities through several mechanisms, including premature deconjugation of the cytotoxic agent in the serum and the presence of the targeted antigen on normal tissues. Given cutaneous adverse events comprise 31.3% of all-grade adverse events in clinical trials involving ADCs, dermatologists are increasingly called upon to manage the cutaneous toxicities caused by these drugs. In this review, we summarize known cutaneous toxicities of the ADCs that have been approved for use by the US Food and Drug Administration to date. Dermatologists can play a key role in recognizing cutaneous reactions associated with ADCs, contributing to guidelines for their management, and aiding during clinical trials to generate detailed morphologic and histopathologic descriptions of cutaneous toxicities caused by ADCs.

Psoriasis in the Era of Targeted Cancer Therapeutics: A Systematic Review on De Novo and Pre-existing Psoriasis in Oncologic Patients Treated with Emerging Anti-neoplastic Agents.

New advancements in medicine have paved the way for targeted therapies and immune checkpoint inhibitors (ICIs), which have become mainstays of cancer therapy. Targeted therapies work by pinpointing specific molecules in cancer pathways and inhibiting their function, while ICIs target irregularities in the immune system and DNA repair, participating in the induction of cell death. Although these agents have demonstrated great efficacy in treating a diverse set of cancers, they can frequently provoke serious dermatologic adverse effects. The side effects caused by an ICI are classified as immune-related adverse events since ICIs are immunomodulating, while the cutaneous side effects of targeted therapies are known as dermatologic adverse effects. Multiple studies have reported psoriasis and psoriasiform eruptions among the side effects observed in neoplastic patients receiving targeted therapies or ICIs. Psoriasis is an immune-mediated disease characterized by overactive T-cells and keratinocytes. To conduct this review, we retrieved 1363 studies from the PubMed database published between 2008 and 2023 using the terms "psoriasis" AND "cancer treatment." Many of these studies aimed to understand how patients with cancer receiving treatment may develop or even achieve psoriasis remission. Given that cancer and psoriasis involve a delicate balance between immune activation and suppression, ICIs and targeted therapies might produce varying effects. The aim of this review was to explore the relationship between psoriasis and cancer therapeutics while also highlighting the need to prioritize proper management of cutaneous side effects in neoplastic patients.

Rare cutaneous adverse reactions associated with GLP-1 agonists: a review of the published literature.

Glucagon-like-peptide-1 (GLP-1) agonists are an emerging class of medications used to manage type 2 diabetes mellitus (T2DM) and weight loss, with demonstrated efficacy in reducing hemoglobin A1c levels, body mass index, and adverse cardiovascular events. While previous studies have reviewed notable cutaneous adverse effects with other antidiabetic medications, little is known about GLP-1 agonist-induced cutaneous reactions. Nevertheless, rare but significant cutaneous adverse reactions have been reported, including but not limited to dermal hypersensitivity reactions, eosinophilic panniculitis, bullous pemphigoid, and morbilliform drug eruptions. As GLP-1 induced cutaneous reactions are diverse, diagnosis requires clinical suspicion, thorough history-taking, and supportive histopathological findings when available. Management involves cessation of the offending agent with a tailored regimen to address inflammatory and/or immunogenic etiologies as well as irritative symptoms. This review aims to consolidate available information from case reports and case series regarding rare skin-related adverse outcomes due to GLP-1 use, aiming to provide a comprehensive overview of the presentation, pathogenesis, and management for dermatologists and other clinicians.

Defining D-irAEs: consensus-based disease definitions for the diagnosis of dermatologic adverse events from immune checkpoint inhibitor therapy.

With an increasing number of patients eligible for immune checkpoint inhibitors, the incidence of immune-related adverse events (irAEs) is on the rise. Dermatologic immune-related adverse events (D-irAEs) are the most common and earliest to manifest, often with important downstream consequences for the patient. Current guidelines lack clarity in terms of diagnostic criteria for D-irAEs. The goal of this project is to better define D-irAE for the purposes of identification, diagnosis, and future study of this important group of diseases.The objectives of this project were to develop consensus guidance for an approach to D-irAEs including disease definitions and severity grading. Knowing that consensus among oncologists, dermatologists, and irAE subspecialists would be critical for usability, we formed a Dermatologic irAE Disease Definition Panel. The panel was composed of 34 experts, including oncologists, dermatologists, a rheumatologist, and an allergist/immunologist from 22 institutions across the USA and internationally. A modified Delphi consensus process was used, with two rounds of anonymous ratings by panelists and two virtual meetings to discuss areas of controversy. Panelists rated content for usability, appropriateness, and accuracy on 9-point scales in electronic surveys and provided free text comments. A working group aggregated survey responses and incorporated them into revised definitions. Consensus was based on numeric ratings using the RAND/UCLA Appropriateness Method with prespecified definitions.Following revisions based on panelist feedback, all items received consensus in the second round of ratings. Consensus definitions were achieved for 10 core D-irAE diagnoses: ICI-vitiligo, ICI-lichen planus, ICI-psoriasis, ICI-exanthem, ICI-bullous pemphigoid, ICI-Grover's, ICI-eczematous, ICI-eruptive atypical squamous proliferation, ICI-pruritus without rash, and ICI-erosive mucocutaneous. A standard evaluation for D-irAE was also found to reach consensus, with disease-specific exceptions detailed when necessary. Each disorder's description includes further details on disease subtypes, symptoms, supportive exam findings, and three levels of diagnostic certainty (definite, probable, and possible).These consensus-driven disease definitions standardize D-irAE classification in a useable framework for multiple disciplines and will be the foundation for future work. Given consensus on their accuracy and usability from a representative panel group, we anticipate that they can be used broadly across clinical and research settings.
