The aims of this study were to investigate, in cutaneous malignant melanoma (MM), the integrity of nuclear vitamin D receptor (VDR) signalling, as implied by VDR subcellular location; to investigate the relationship between VDR and tumour progression and the inhibitory effect on VDR by mitogen-activated protein kinase (MAPK) overactivity. Archived tissue from 34 benign melanocytic naevi, 149 MMs and 44 matched metastases were stained by immunohistochemistry for VDR and a subset of primary MMs were stained for phosphorylated-extracellular signal-regulated kinase as a marker of MAPK activity...

About 3 million surgical pigmented skin lesion biopsies are performed each year in the USA alone to diagnose fewer than 200 000 new cases of invasive melanoma and melanoma in situ using the current standard of care that includes visual assessment and histopathology. A recently described noninvasive adhesive patch-based gene expression rule-out test [pigmented lesion assay (PLA)] may be helpful in identifying high-risk pigmented skin lesions to aid with surgical biopsy decisions. The main objective of this utility study was to determine the real-world clinical performance of PLA use and assess how the PLA changes physician behavior in an observational cohort analysis of 381 patients assessed with the PLA...

Conditional survival in patients with localized primary cutaneous malignant melanoma (CMM) is well described. However, conditional recurrence-free survival (RFS) has not been investigated before. The aim of this study was to determine conditional RFS and test for time dependency in prognostic factors in patients with localized stage I-II CMM. This study included 1437 CMM patients registered in one region of Sweden during 1999-2012 followed up through 31 December 2012. To identify first recurrence of CMM disease, data from a care data warehouse, the pathology and radiology department registries were used...

Targeted therapy combination (TTC: antiRAF+antiMEK) is known to improve metastatic melanoma survival. Few severe skin toxicities (grade ≥3) are described with first-line TTC (17% for vemurafenib+cobimetinib and none for dabrafenib+trametinib) in a phase III trial. Among our 42 patients treated by TTC between January 2014 and March 2017, 4.8% (2/42) of those treated in the first line presented severe skin rash versus 19% (8/42) of patients treated in the second line after previous immunotherapy. In particular, we observed one case of Stevens-Johnson syndrome and four cases of severe drug reaction with eosinophilia and systemic symptoms syndrome under TTC in patients who had received immunotherapy previously...

Factors influencing melanoma survival include sex, age, clinical stage, lymph node involvement, as well as Breslow thickness, presence of tumor-infiltrating lymphocytes based on histological analysis of primary melanoma, mitotic rate, and ulceration. Identification of genes whose expression in primary tumors is associated with these key tumor/patient characteristics can shed light on molecular mechanisms of melanoma survival. Here, we show results from a gene expression analysis of formalin-fixed paraffin-embedded primary melanomas with extensive clinical annotation...

Malignant melanoma solitary metastases to bone or skeletal muscle occur in 0.8% of patients. The aim of this study was to evaluate features of skeleton and muscle metastases with multimodality imaging and review the oncological outcome. Thirteen patients with melanoma metastases from January 2006 to February 2016 were included. Histologic confirmation was obtained. Imaging studies included computed tomography (CT), MRI, and/or positron emission tomography/CT. Treatment received and BRAF status were recorded...

The use of monoclonal antibodies against programmed cell death protein 1 (anti-PD-1) has markedly transformed the management of melanoma. However, only a minority of patients treated with anti-PD-1 therapy show a response to therapy and some of them develop immune-related adverse events that can be managed with steroids or anticytokine therapy. A recent study published in Nature Communications has reported that treatment with anti-PD-1 in a tumor necrosis factor-deficient environment may lead to higher response rates to immunotherapy by reducing tumor-infiltrating lymphocytes death, accumulating dendritic cells within cancer, and downregulating T-cell immunoglobulin and mucin-domain-containing-3 expression...

Immune checkpoint inhibitors targeting the programmed cell death (PD)-1 receptor have dramatically changed the landscape of metastatic melanoma treatment. Nevertheless, these immuno-modulatory agents have associated side effects, including dermatologic manifestations. To this end, we report a patient with metastatic melanoma that was treated with PD-1 inhibitor, and subsequently developed inflammation of existing seborrheic keratosis lesions and new verrucous keratoses, a cutaneous side effect that has not been previously reported to our knowledge...

Nivolumab, a completely human programmed death-1 inhibitor antibody, was first approved by the Food and Drug Administration for patients with advanced malignant melanoma resistant to other modalities of treatment. In 2015, it received approval as the first line of treatment for malignant melanoma. We aimed to synthesize evidence from published randomized-controlled trials on the safety and efficacy of nivolumab, either alone or in combination with ipilimumab, in the management of advanced unresectable melanoma...

A history of melanoma within the preceding 5 years is commonly considered a contraindication to solid organ transplantation. We investigated how a pretransplant history of melanoma impacts patient survival and melanoma recurrence. Institutional Review Board approval was obtained, and Duke's retrospective database was used to identify 4552 patients who underwent a solid organ transplant at Duke University from 1 January 2001 to 31 December 2016. Data with regard to the transplant, melanoma characteristics, rejection episodes, and survival were recorded...

Acral lentiginous melanoma (ALM) is a unique histopathological subtype of melanoma with a poorer prognosis than other cutaneous melanomas. This study aims to evaluate the clinicopathological characteristics, metastatic pattern, prognostic factors, response to systemic therapy, and overall survival (OS) of ALM in a White population. This is a retrospective study of patients who were diagnosed and/or treated for ALM at the Department of Dermatology of the University Hospital Zurich, Switzerland, from January 2005 to December 2015...

Age is an important prognostic factor in melanoma; notably, elderly patients tend to present with advanced stage skin melanoma (SM) and worse outcome. Moreover, SM is an immunogenic cancer, and its interaction with the aging immune system could have an effect on biologic behaviour of this disease. Tumour-infiltrating lymphocytes (TILs) could represent the host response in SM; it has been shown that higher grade of TILs is associated with better survival. Moreover, programmed death ligand 1 (PD-L1) and cyclooxygenase-2 (COX-2) are potential markers of host immune response and inflammation...

There is a scarcity of available data on unmet information needs (UINs) of melanoma patients (MPs) from Germany and of MPs with clinical stage IV. In a multicenter cross-sectional survey, we explored the UINs of 529 MPs by applying a standardized questionnaire. Subgroup differences in scope and contents of UINs were determined by univariate analyses. Predictors of the presence of UINs were identified by binary logistic regression. Overall, 55% of MPs reported UINs. Most MPs felt poorly or not informed about psychosocial support (24-31%)...

Neutrophil-to-lymphocyte ratio (NLR) has been shown to be prognostic in several solid malignancies. There are limited data regarding its value during novel therapies in patients with melanoma. The aim of the study was to assess the practical utility of this ratio in patients with BRAF-mutant melanoma treated with a combination of BRAF and MEK inhibitors (BRAFi/MEKi). We included 215 patients with inoperable or metastatic melanoma who underwent BRAFi/MEKi treatment between October 2015 and June 2017. Baseline NLR and other complete blood count-derived inflammatory markers were tested for association with overall survival and progression-free survival in univariate and multivariate models...

Anti-PD-1 targeted immunotherapies have revolutionized the treatment of advanced melanoma and other tumor entities, and long disease-free intervals have been reported in responding patients. However, a considerable number of patients still progress rapidly after the start of anti-PD-1 antibodies. Here, we document two patients, 78 and 85-year old, who suffered from advanced BRAF-V600 wild-type melanoma and received pembrolizumab 2 mg/kg every 3 weeks as the first systemic treatment. After only one, respectively, two infusions of pembrolizumab, both patients developed melanuria and diffuse melanosis cutis (DMC) on sun-exposed areas of their skin...

Pregnancy-associated melanoma is defined as melanoma diagnosed during pregnancy or within 1 year of delivery. The association of pregnancy with melanoma is well known, but its underlying molecular mechanisms of association are poorly understood. The aim was to assess the expression of apoptosis-related genes in melanoma tumors during pregnancy in an attempt to elucidate the molecular mechanisms underlying apoptosis-driven activation of melanoma cells in this period. Mice were allocated across two experimental groups (nonpregnant and pregnant) and implanted with the melanoma cell line BF16-F10...

Epidemiological studies have assessed the association between excision repair cross-complementing group 2 (ERCC2) Lys751Gln and Asp312Asn polymorphisms and melanoma risk with conflicting results. Relevant articles were searched from PubMed, Embase, and Web of Science with a time limit of 3 September 2016. Pooled odds ratio (OR) with 95% confidence interval (CI) was used to assess the strength of the association. We performed this meta-analysis with 12 studies including 6157 cases and 8873 controls for Lys751Gln and nine studies including 5037 cases and 7542 controls for Asp312Asn polymorphism...

Denosumab is a monoclonal antibody against RANK ligand with a role in the prevention of skeletal-related events and is also known to possess antitumor properties. In this retrospective review, we aim to evaluate the synergist effect of a combination therapy with immune checkpoint inhibitors and denosumab in malignant melanoma patients. Patients of 18 years of age or older with a diagnosis of malignant melanoma who have received immune checkpoint inhibitors and denosumab between June 2015 and May 2017 were divided into two cohorts: cohort A (immune checkpoint inhibitors only) and cohort B (immune checkpoint inhibitors and denosumab)...
