AIMS: Diagnosis of undifferentiated pleomorphic sarcoma (UPS) may be challenging, as other lesions with undifferentiated spindle cell morphology must be excluded, including melanoma. Microphthalmia-associated transcription factor (MiTF) stains nevi and epithelioid melanomas, as well as some mesenchymal neoplasms. We evaluated the prevalence of MiTF and melanocytic markers in UPS and a subset of atypical fibroxanthoma (AFX). METHODS AND RESULTS: MiTF, SOX10, Melan-A, HMB45, and S100 immunostains were performed on resection specimens from 19 UPS and 5 AFX...

Changes in melanocytic nevi during pregnancy are frequently attributed to the new hormonal milieu and are dismissed without concern for malignancy. Recent studies suggest that pregnancy itself does not induce significant change in nevi, and delays in the assessment of changing moles may contribute to the often more advanced nature of melanomas diagnosed during or soon after pregnancy. Nevi on the breasts and abdomen can grow as a result of skin expansion, but studies have found no significant changes in nevi located in more stable areas such as the back or lower extremities...

Oral cavity mucosal melanomas (OCMM) represent only 3% of all malignant melanomas. Surgery is the mainstay of treatments and it is often followed by adjuvant radiotherapy. The role of adjuvant immunotherapy and/or chemotherapy is still debated and to date neither treatment is routinely used. From January 1990 to January 2010, we have collected from our database data of 20 patients with a histologically proven diagnosis of OCMM. Upfront surgery, followed by adjuvant radiotherapy was performed in 16/20 (80%) patients...

The aims of this paper are to describe the incidence trends of invasive cutaneous melanoma in the Canton of Zurich and to evaluate clinical and pathological factors such as cancer subtype, localization, age and Breslow thickness. A retrospective analysis was carried out with data from the population-based Cancer Registry of Zurich and Zug located in Zurich. A total of 8469 cases in 8034 different patients of invasive cutaneous melanoma were registered for the period 1980-2010 in the Canton of Zurich. Incidence trends were age standardized to the European standard population...

In patients with ipilimumab (IPI)-refractory melanoma, the anti-programmed cell death proteins 1 (PD1s) nivolumab (NIV) and pembrolizumab (PEM) are considered to be a new standard of treatment. Few data are available on anti-PD1 safety in patients who develop IPI-related severe adverse events (AEs) (grade≥3). The aim of this study was to compare the anti-PD1 safety and efficacy in patients with previous severe toxicity to IPI versus in those showing moderate and no previous IPI-related AEs. This single institution-based observational study included all patients treated with anti-PD1 (PEM or NIV) and previously treated with IPI for unresectable stage III or IV melanoma...

Tumor therapy needs new approaches in order to improve efficacy and reduce toxicity of the current treatments. The acidic microenvironment and the expression of high levels of endogenous non-telomerase reverse transcriptase (RT) are common features of malignant tumor cells. The anti-acidic proton pump inhibitor Lansoprazole (LAN) and the non-nucleoside RT inhibitor Efavirenz (EFV) have shown independent antitumor efficacy. LAN has shown to counteract drug tumor resistance. We tested the hypothesis that combination of LAN and EFV may improve the overall antitumor effects...

Arylsulfatase B (ARSB; N-acetylgalactosamine 4-sulfatase) is reduced in several malignancies, but levels in melanoma have not been investigated previously. Experiments were performed in melanoma cell lines to determine ARSB activity and impact on melanoma invasiveness. ARSB activity was reduced ~50% in melanoma cells compared to normal melanocytes. Silencing ARSB significantly increased the mRNA expression of chondroitin sulfate proteoglycan(CSPG)4 and pro-matrix metalloproteinase(MMP)-2, known mediators of melanoma progression...

Genitourinary melanoma accounts for 0.1-0.2% of melanoma, the scrotum being its rarest location. We report about an 85-year-old patient who was referred to our outpatient clinic due to the presence of a scrotum black papule for 20 months. Wide local excision was performed, and histology revealed a malignant melanoma. Chest and abdominal CT revealed metastatic disease, so chemotherapy, immunotherapy and radiotherapy were administered. We describe the evolution over 1 year in this unusual location, as well as complications and the currently available therapeutic options to cure this disease...

REVIEW

The clinical development of checkpoint inhibitor-based immunotherapy has ushered in an exciting era of anticancer therapy. Durable responses can be seen in patients with melanoma and other malignancies. Although monotherapy with PD-1 or PD-L1 agents are typically well tolerated, the risk of immune-related adverse events increases with combination regimens. The development of predictive biomarkers is needed to optimise patient benefit, minimise risk of toxicities, and guide combination approaches. The greatest focus has been on tumour-cell PD-L1 expression...

Dysplastic (atypical) naevi have long been subject to discussion with regard to their nature; even their existence has been doubted. Recently, the atypical naevus has been formally identified by molecular genetic characteristics as an intermediate lesion between banal naevi and melanoma. However, the atypical naevus, as long as it is stable and asymptomatic, is regarded as a benign lesion that does not warrant excision. Atypical naevi can occur in families in which melanoma is prevalent, and those patients need to be included in regular surveillance by a dermatologist...

BACKGROUND: Lactam cyclized alpha-melanocyte stimulating hormone (α-MSH) analogues exhibit high stability and affinity for the MC1-R receptors over expressed in melanoma cells. Recently, we reported a novel <sup>99m</sup>Tc-HYNIC-cycMSH<sub>4-13</sub> analogue with the HYNIC chelator directly attached to the lactam cyclized ring. OBJECTIVE: In this study we proposed the introduction of a 6-aminohexanoic acid (Ahx) linker between the HYNIC chelator and lactam cyclized peptide cycMSH4-13 to reduce steric hindrance and improve the melanoma targeting and imaging proprieties of the radiolabeled peptide...

Genomic medicine has revolutionized disease risk identification and subsequent risk reduction interventions. Skin cancer risk genomic feedback is a promising vehicle to raise awareness and protective behaviors in the general population, including Hispanics who are largely unaware of their risks. Yet, personalized genomics currently has limited reach. This study is the initial phase of a randomized controlled trial investigating the personal utility and reach of genomic testing and feedback for melanoma. Semi-structured cognitive interviews (N = 28), stratified across education level, were conducted to assess the comprehension and acceptability of translated skin cancer genomic risk education materials with Spanish-speaking Hispanic primary care patients...

Here, we present data on the effects of emu oil, obtained from emu (Dromaius novaehollandiae) fat deposits, on melanogenesis in B16F1 murine melanoma cells. The cells were cultured in media containing different concentrations of emu oil, and the melanin content of these cells was measured using a microplate reader. Next, melanin content was measured for cells cultured with α-melanocyte-stimulating hormone. This article reports the different melanin contents as μg melanin/mg cellular protein, by using bar graphs with error bars...

Over 20% of cancer patients will develop brain metastases. Prognosis is currently extremely poor, largely owing to late-stage diagnosis. We hypothesized that biofluid metabolomics could detect tumours at the micrometastatic stage, prior to the current clinical gold-standard of blood-brain barrier breakdown. Metastatic mammary carcinoma cells (4T1-GFP) were injected into BALB/c mice via intracerebral, intracardiac or intravenous routes to induce differing cerebral and systemic tumour burdens. B16F10 melanoma and MDA231BR-GFP human breast carcinoma cells were used for additional modelling...

A reduced number and/or reduced activity of natural killer (NK) cells, which are important for defense against a variety of cancers and viral infections, occur under various stress conditions and in patients with various diseases. In this article, we report that the 30% to 50% ethanol precipitate of oyster extract (EPOE50) dose-dependently enhanced the activity of mouse spleen NK cells in vitro and in vivo. The activity of EPOE50 was eluted with a molecular weight of about 2000 by gel filtration and was inactivated by periodate but not by proteinase K...

A Testori, S Ribero, V Bataille
In transit metastases (ITM) from extremity or trunk melanomas are subcutaneous or cutaneous lymphatic deposits of melanoma cells, distant from the primary site but not reaching the draining nodal basin. Superficial ITM metastases develop in 5-10% of melanoma patients and are thought to be caused by cells spreading along lymphatics; ITM appear biologically different from distant cutaneous metastases, these probably due to a haematogenous dissemination. The diagnosis is usually clinical and by patients, but patients need to be adequately educated in the recognition of this clinical situation...

Melanomas are disease entities driven in part by the mitogen activated protein kinase (MAPK) pathway. The TCGA network recently defined four genetic subtypes based on the most prevalent significantly mutated genes, including mutant BRAF, mutant RAS (N/H/K), mutant NF1, and Triple wild-type melanoma (harboring none of the aforementioned mutations, but instead includes KIT, GNA and GNAQ mutations). The successful development of kinase inhibitors marked a milestone in the treatment of metastatic melanoma. Combination treatment with a BRAF- and MEK-inhibitor is the current standard of care for inoperable stage IIIC/IV BRAF-mutated melanoma...
