Evaluation of S100A8/A9 and neutrophils as prognostic markers in metastatic melanoma patients under immune-checkpoint inhibition.

Immune-checkpoint inhibitors (ICIs) have revolutionized melanoma treatment, yet approximately half of patients do not respond to these therapies. Identifying prognostic biomarkers is crucial for treatment decisions. Our retrospective study assessed liquid biopsies and tumor tissue analyses for two potential biomarkers: danger-associated molecular pattern (DAMP) S100A8/A9 and its source, neutrophils.

Improved survival of advanced melanoma patients receiving immunotherapy with concomitant antithrombotic therapy - A multicenter study on 2419 patients from the prospective skin cancer registry ADOReg.

Background: Cancer immunotherapy has revolutionized melanoma treatment, but the high number of non-responders still emphasizes the need for improvement of therapy. One potential avenue for enhancing anti-tumor treatment is through the modulation of coagulation and platelet activity. Both have been found to play an important role in the tumor microenvironment, tumor growth and metastasis.

Mutation analysis in individual circulating tumor cells depicts intratumor heterogeneity in melanoma.

Circulating tumor DNA (ctDNA) is the cornerstone of liquid biopsy diagnostics, revealing clinically relevant genomic aberrations from blood of cancer patients. Genomic analysis of single circulating tumor cells (CTCs) could provide additional insights into intra-patient heterogeneity, but it requires whole-genome amplification (WGA) of DNA, which might introduce bias. Here, we describe a novel approach based on mass spectrometry for mutation detection from individual CTCs not requiring WGA and complex bioinformatics pipelines.

Differential predictive value of tissue-specific PD-L1 expression scores in adjuvant immunotherapy of melanoma.

Background: Adjuvant treatment of stage II-IV melanoma with PD-1-based immune checkpoint inhibitors (ICI) has improved relapse-free survival (RFS) and has therefore become a standard-of-care treatment option. Approximately 25%-30% of patients still recur within 1 year. Predictive biomarkers reflecting real-world data are desired.

High Serum Levels of CCL20 Are Associated with Recurrence and Unfavorable Overall Survival in Advanced Melanoma Patients Receiving Immunotherapy.

Background: Immune checkpoint inhibition has revolutionized melanoma therapy, but many patients show primary or secondary resistance. Biomarkers are, therefore, urgently required to predict response prior to the initiation of therapy and to monitor disease progression.

Methods: In this prospective study, we analyzed the serum C-C motif chemokine ligand 20 (CCL20) concentration using an enzyme-linked immunosorbent assay.

Patient-reported outcomes of topical finasteride/minoxidil treatment for male androgenetic alopecia: A retrospective study using telemedical data.

Background: Oral finasteride and topical minoxidil are the current standard of care for male androgenetic alopecia and a combination of the two treatments can be considered for greater efficacy. Clinical trials of topical finasteride have also yielded promising results, but routine care data are lacking.

Aims: To examine patient-reported outcomes of men with androgenetic alopecia who received topical finasteride admixed with minoxidil compared to the current standard of care (oral finasteride).

C-reactive protein flare predicts response to checkpoint inhibitor treatment in melanoma.

Background: The treatment of melanoma has been revolutionized by the use of immune checkpoint inhibition (ICI), but many patients do not benefit. Furthermore, immune-related adverse events may occur during therapy. A predictive biomarker is needed to reliably identify patients benefitting.

Patient-reported treatment outcomes and safety of direct-to-consumer teledermatology for finasteride treatment in male androgenetic alopecia: A cross-sectional study.

Objective: The use of direct-to-consumer (DTC) teledermatology platforms has increased, particularly for androgenetic alopecia (AGA). However, little is known about the efficacy and safety of these platforms. This study aimed to investigate the patient-reported treatment outcomes and safety of DTC teledermatology for the finasteride treatment of male AGA.

Online Traffic Analysis of Direct-to-Consumer Websites for Hair Loss Treatment and Characterization of Finasteride Patients on a Platform in Germany: A Potential Paradigm Shift in the Treatment of Androgenetic Alopecia.

Purpose: The number of online prescription platforms (OPPs) offering telemedical diagnosis and treatment, including finasteride, for androgenetic alopecia (AA) by using medical questionnaires (MQs) has increased. This type of care delivery differs completely from traditional forms. This study aimed to investigate a potential paradigm shift in AA treatment by measuring the extent of traffic generated by OPPs that exclusively treat AA and furthermore by characterizing sociodemographic features of men undergoing finasteride treatment from an OPP in Germany.

The potential of telemedicine for dermatological care of pediatric patients in Germany.

Background And Objectives: Skin diseases are a common reason for consultations in pediatric practice. The present study aims to characterize the dermatological requests of resident pediatric specialists using teledermatology in Germany.

Patients And Methods: This analysis of consultation requests, submitted by pediatricians to a designated pediatric dermatologist via a telemedical consultation system (PädExpert) using the store-and-forward technology, was performed between February 2021 and December 2021.

A Rejected Hypothesis: Phenomenon of High Treatment Adherence in Direct-to-Consumer Teledermatology Despite Lack of Direct Physician-Patient Interaction.

Activated Eosinophils Predict Longer Progression-Free Survival under Immune Checkpoint Inhibition in Melanoma.

Immune checkpoint inhibition (ICI) has yielded remarkable results in prolonging survival of metastatic melanoma patients but only a subset of individuals treated respond to therapy. Success of ICI treatment appears to depend on the number of tumor-infiltrating effector T-cells, which are known to be influenced by activated eosinophils. To verify the co-occurrence of activated eosinophils and T-cells in melanoma, immunofluorescence was performed in 285 primary or metastatic tumor tissue specimens from 118 patients.
