PURPOSE: Clinical trials commonly use physician-adjudicated adverse event (AE) assessment via the common terminology criteria for adverse events (CTCAE) for decision-making. Patient-reported health-related quality of life (HRQoL) data are becoming more frequent in oncology; however, the relationship between physician-adjudicated AE assessment and HRQoL is understudied. METHODS: Data from a phase II trial (clinicaltrials.gov identifier: NCT01143402) where patients with metastatic uveal melanoma were randomized to receive selumetinib, an oral MEK inhibitor, or chemotherapy were analyzed...

INTRODUCTION: Ipilimumab is an immune checkpoint inhibitor targeting cytotoxic T-lymphocyte associated antigen 4 (CTLA4), approved to treat metastatic melanoma. It was the first therapy shown to prolong survival in a large, randomized clinical trial. However, immune-related adverse events are common and can be severe. Enterocolitis is a common adverse event with ipilimumab, but enteritis without colitis has not been previously described. CASE REPORT: An 83-year-old man presented to our hospital with grade 3 diarrhea for 5 days...

Recently, immunotherapeutic drugs, including PD-1 inhibitors (nivolumab, pembrolizumab), PD-L1 inhibitors (atezolizumab, avelumab), and CTLA4 inhibitors (ipiliumumab), have emerged as important additions to the armamentarium against certain malignancies and have been incorporated into therapeutic protocols for first-, second-, or third-line agents for these metastatic cancers. Immune checkpoint inhibitor nivolumab is currently FDA approved for the treatment of patients with metastatic malignant melanoma [Redman et al...

Since nivolumab significantly prolongs survival in patients with metastatic melanoma, the number of patients administered nivolumab is increasing, but only 30-40% of patients who received nivolumab monotherapy experienced objective tumor regression. Therefore, enhancing its anti-tumor immune response is of great interest to dermato-oncologists. In this report, we present a case of multiple metastatic melanomas in the lung successfully treated with nivolumab (2 mg/kg every 3 weeks for 12 weeks) followed by ipilimumab (3 mg/kg every 3 weeks for 9 weeks), but with severe liver dysfunction...

BACKGROUND: Electrochemotherapy (ECT) is increasingly used in the treatment of primary and secondary skin tumors, but little is known about the pathologic mechanism responsible for tumor cell destruction in humans. Knowledge of detailed mechanism of host response after ECT may improve the treatment efficacy related to patient selection and technique refinements. AIM: The aim of the study was to investigate the histopathology and mechanism of cell death after ECT in cutaneous melanoma metastases...

Oxidative stress plays a role in UV-induced melanoma, which may arise from melanocytic nevi. We investigated whether oral administration of the antioxidant N-acetylcysteine (NAC) could protect nevi from oxidative stress in vivo in the setting of acute UV exposure. The minimal erythemal dose (MED) was determined for 100 patients at increased risk for melanoma. Patients were randomized to receive a single dose (1,200 mg) of NAC or placebo, in double-blind fashion, and then one nevus was irradiated (1-2 MED) using a solar simulator...

BACKGROUND/AIM: Many patients with brain metastases from melanoma receive whole-brain radiotherapy (WBRT). WBRT-regimens must consider the patient's prognosis in order to deliver the best therapy. PATIENTS AND METHODS: Seven factors were correlated to intracerebral control and survival after WBRT alone in 92 patients with melanoma: WBRT regimen, age at WBRT, gender, Karnofsky performance score (KPS), number of brain lesions, number of extracranial metastatic sites, and time from melanoma diagnosis to WBRT...

BACKGROUND/AIM: To validate the melanoma nomogram and improve its function in prediction of nodal dissemination by incorporating a molecular marker in the model. Microphthalmia transcription factor (MITF) is an important regulator of melanocyte homeostasis and differentiation. We have shown that the grade of MITF expression in primary melanoma cells can serve as a predictor of nodal status. Many efforts to identify the nodal spread in cutaneous melanoma using non-invasive means have been recently undertaken...

AIM: The feasibility of videoscopic inguinal-iliac-obturator lymphadenectomy (VIIOL) was assessed in 20 patients with melanoma and compared with a retrospective sample of 24 patients undergoing standard 'open' technique (IIOL). RESULTS: No postoperative death occurred; the mean operative time was lower in the IIOL series (190 min vs. 302 min) but the quality of life was greatly improved in the VIIOL group thanks to earlier bladder catheter removal, no nasogastric suction, less pain, earlier mobilization, lower in-hospital stay, and earlier resumption of daily activities (27...

E-Cadherin and N-cadherin are important components of epithelial-mesenchymal transition (EMT). The majority of studies on EMT in melanoma have been performed with cultured cell lines or pooled melanoma samples. The goal of our study was to evaluate the expression of E-cadherin and N-cadherin in matched tissue samples from primary and metastatic sites of melanoma and to determine the correlation with survival outcome. We analyzed tissues from 42 melanoma primary lesions and their corresponding metastases, as well as 53 benign nevi, for expression levels of E-cadherin and N-cadherin using immunohistochemical methods...

BACKGROUND: Isothiocyanates are constituents of cruciferous vegetables which have been associated with reduced cancer risk partially through their ability to induce apoptosis in malignant cells including melanoma. MATERIALS AND METHODS: We have utilized human malignant melanoma (A375), epidermoid carcinoma (A431) and immortalized keratinocyte (HaCaT) cells exposed to various isothiocyanates, under different experimental conditions. RESULTS: An experimental in vitro model utilizing low isothiocyanate concentrations (0...

REVIEW
Radhe Mohan, David Grosshans
In principle, proton therapy offers a substantial clinical advantage over the conventional photon therapy. This is because of the unique depth-dose characteristics of protons, which can be exploited to achieve significant reductions in normal tissue doses proximal and distal to the target volume. These may, in turn, allow escalation of tumor doses, greater sparing of normal tissues, thus potentially improving local control and survival while at the same time reducing toxicity and improving quality of life. Protons, accelerated to therapeutic energies ranging from 70 to 250MeV, typically with a cyclotron or a synchrotron, are transported to the treatment room where they enter the treatment head mounted on a rotating gantry...

Natalizumab (NTZ) is a monoclonal antibody targeting the α4β1 integrin (CD49d/CD29), very late antigen-4 (VLA-4), which is approved for treatment of relapsing-remitting multiple sclerosis (RR-MS). A possible association between NTZ treatment and a higher risk of melanoma is under debate. Natural Killer (NK) cells, which express VLA-4, represent an innate barrier limiting spreading of melanoma under steady state conditions. Indeed, because of their expression of activating receptors, they are very efficient in recognizing and killing melanoma cells without the need of a previous priming...

The functional properties of actin-regulating formin proteins are diverse and in many cases cell-type specific. FHOD1, a formin expressed predominantly in cells of mesenchymal lineage, bundles actin filaments and participates in maintenance of cell shape, migration and cellular protrusions. FHOD1 participates in cancer-associated epithelial to mesenchymal transition (EMT) in oral squamous cell carcinoma and breast cancer. The role of FHOD1 in melanomas has not been characterized. Here, we show that FHOD1 expression is typically strong in cutaneous melanomas and cultured melanoma cells while the expression is low or absent in benign nevi...

Contemporary immunotherapies (e.g., immune checkpoint inhibitors), which enhance the immune response to cancer cells, improve clinical outcomes in several malignancies. A recent study reported the cases of two patients with metastatic melanoma who developed fatal myocarditis during ipilimumab and nivolumab combination immunotherapy; these examples highlight the risk of unbridled activation of the immune system.

OBJECTIVE: Anti-MDA5 antibody positive dermatomyositis (DM) and clinically amyopathic DM (CADM) often develop into rapidly progressive interstitial lung disease, but their pathogenesis remains unclear. We observed that sera from DM/CADM patients immunoprecipitated a common 110 kDa polypeptide. We investigated this autoantigen and its clinical significance. METHODS: Autoantibodies were screened in 333 patients with various connective tissue diseases (CTDs) and 20 healthy controls (HCs) by immunoprecipitation with [(35)S]methionine-labeled HeLa cells...

BACKGROUND: Over the past two decades, there has been a rising trend in malignant melanoma incidence worldwide. In 2008, Germany introduced a nationwide skin cancer screening program starting at age 35. The aims of this study were to analyse the distribution of malignant melanoma tumour stages over time, as well as demographic and regional differences in stage distribution and survival of melanoma patients. METHODS: Pooled data from 61 895 malignant melanoma patients diagnosed between 2002 and 2011 and documented in 28 German population-based and hospital-based clinical cancer registries were analysed using descriptive methods, joinpoint regression, logistic regression and relative survival...

BACKGROUND: Our previous study showed that the μ-opioid receptor agonist fentanyl citrate inhibits endothelin-1-and bradykinin-mediated pain responses in mice orthotopically inoculated with melanoma cells. We also demonstrated that bradykinin induces endothelin-1 secretion in melanoma cells. However, the analgesic mechanisms of fentanyl citrate remain unclear. Thus, the present study was conducted to determine whether fentanyl citrate affects bradykinin-induced endothelin-1 secretion in B16-BL6 melanoma cells...

A type I transmembrane protein, podoplanin (PDPN), is expressed in several normal cells such as lymphatic endothelial cells or pulmonary type I alveolar cells. We recently demonstrated that anticanine PDPN monoclonal antibody (mAb), PMab-38, recognizes canine PDPN of squamous cell carcinomas, but does not react with lymphatic endothelial cells. Herein, we investigated whether PMab-38 reacts with canine melanoma. PMab-38 reacted with 90% of melanoma cells (9/10 cases) using immunohistochemistry. Of interest, PMab-38 stained the lymphatic endothelial cells and cancer-associated fibroblasts in melanoma tissues, although it did not stain any lymphatic endothelial cells in normal tissues...
