Uveal melanoma (UM), a rare cancer of the eye, is distinct from cutaneous melanoma by its etiology, the mutation frequency and profile, and its clinical behavior including resistance to targeted therapy and immune checkpoint blockers. Primary disease is efficiently controlled by surgery or radiation therapy, but about half of UMs develop distant metastasis mostly to the liver. Survival of patients with metastasis is below 1 year and has not improved in decades. Recent years have brought a deep understanding of UM biology characterized by initiating mutations in the G proteins GNAQ and GNA11...

BACKGROUND: Although a well-established causative relationship exists between smoking and several epithelial cancers, the association of smoking with metastatic progression in melanoma is not well studied. We hypothesized that smokers would be at increased risk for melanoma metastasis as assessed by sentinel lymph node (SLN) biopsy. METHODS: Data from the first international Multicenter Selective Lymphadenectomy Trial (MSLT-I) and the screening-phase of the second trial (MSLT-II) were analyzed to determine the association of smoking with clinicopathologic variables and SLN metastasis...

There are reported cases of diphencyprone used in treating cutaneous metastases of melanoma. Here, we report a patient with previous primary melanoma on his left back treated with surgical excision and lymphadenectomy, followed by radiotherapy for the recurrent tumor on the primary site. Despite radiotherapy and treatment with dabrafenib and trametinib, in-transit metastases have developed and topical diphencyprone was applied to these metastases. Six weeks later, the patient developed fever and a spreading erythematous tender indurated plaque covering the left side of the body including axillae, back, and flank, clinically suggestive of cellulitis...

INTRODUCTION: Anorectal amelanotic melanoma (AAMM) is a rare disease with poor prognosis. A standard treatment strategy for AAMM has not been established. PRESENTATION OF CASE: We report a case of successful treatment of AAMM with nivolumab. A 67-year-old man was referred for colonoscopy which revealed type I tumor in the rectum. AAMM was diagnosed with immunostaining histopathological biopsy findings. Enhanced computed tomography (ECT) revealed the rectal tumor without distant organ metastasis...

BACKGROUND: The EORTC 18071 phase 3 trial compared adjuvant ipilimumab with placebo in patients with stage III melanoma. The primary endpoint, recurrence-free survival, was significantly longer in the ipilimumab group than in the placebo group. Investigator-reported toxic effects of ipilimumab consisted mainly of skin, gastrointestinal, endocrine, and hepatic immune-related adverse events. Adjuvant treatment with ipilimumab in this setting was approved in October, 2014, by the US Food and Drug Administration based on the results of the primary outcome of this trial...

Metastatic uveal melanoma (UM) patients usually die within one year of diagnosis, emphasizing an urgent need to develop new treatment strategies. The liver is the most common site of metastasis. Mitogen-activated protein kinase kinase (MEK) inhibitors improve survival in V600 BRAF-mutated cutaneous melanoma patients but have limited efficacy in UM patients. Our previous work showed that HGF signaling elicits resistance to MEK inhibitors in metastatic UM. In this study, we demonstrate that expression of two BH3-only family proteins, Bim-EL and BMF, contributes to HGF-mediated resistance to MEK inhibitors...

BACKGROUND: Electrochemotherapy (ECT) is an effective local treatment for cutaneous metastasis. Treatment involves the administration of chemotherapeutic drugs followed by delivery of electrical pulses to the tumour. The aim of this study was to investigate the effectiveness of ECT in cutaneous metastases of melanoma and to identify factors which affect (beneficially or adversely) the outcome. METHODS: 13 cancer centres in the International Network for Sharing Practices on Electrochemotherapy (INSPECT) consecutively and prospectively uploaded data to a common database...

BACKGROUND: A significant proportion of patients with American Joint Committee on Cancer (AJCC)-defined early-stage cutaneous melanoma have disease recurrence and die. A 31-gene expression profile (GEP) that accurately assesses metastatic risk associated with primary cutaneous melanomas has been described.

The presence of tumor infiltrating lymphocytes is a favorable prognostic factor in cutaneous melanoma, but their clinicopathological significance in the intratumoral compartment compared to the peritumoral compartment is unclear. We investigated the clinicopathologic significance of tumor-infiltrating lymphocytes and lymphocyte score in intra- and peritumoral compartments in 177 Korean patients who had undergone surgical excision of cutaneous melanoma. No significant correlation was observed between various clinicopathologic factors and the presence of intratumoral lymphocytes...

Nearly one-third of all melanoma patients will experience disease recurrence and the majority of the relapses eventually develop metastatic disease as a consequence of disease progression in the early-stage melanoma patients. Although the factors that predict the recurrence have already been described, very few numbers of studies have investigated the natural recurrence history of melanoma. In this retrospective study, we analyzed the time until recurrence along with the patterns and outcomes of the recurrences; thus, we aimed to understand the possible factors that might influence the recurrence course in early-stage cutaneous melanoma at the first relapse...

BACKGROUND: Non-melanoma skin cancer includes basal cell carcinoma and squamous cell carcinoma (SCC). Basal cell carcinoma is the most common and least aggressive but in a low percentage of cases, despite appropriate wide surgical margins, it can be aggressive, producing local invasion, recurrences and distance metastasis. SCC has a more aggressive behaviour invading first the skin, the lymph nodes and less frequently produces distance metastasis OBJECTIVE: To identify the characteristics of recurrent SCC and frequency of new SCC after conventional surgical and primary closure or closure delayed until a histological reporting of tumour-free surgical margins, in order to achieve a better surgical option, in our Mexican population...

Epigenetic alterations are increasingly implicated in metastasis, whereas very few genetic mutations have been identified as authentic drivers of cancer metastasis. Yet, to date, few studies have identified metastasis-related epigenetic drivers, in part because a framework for identifying driver epigenetic changes in metastasis has not been established. Using reduced representation bisulfite sequencing (RRBS), we mapped genome-wide DNA methylation patterns in three cutaneous primary and metastatic melanoma cell line pairs to identify metastasis-related epigenetic drivers...

Access of melanoma cells to the cutaneous vasculature either via lymphatic invasion or angiotropism is a proposed mechanism for metastasis. Lymphatic invasion is believed to be a mechanism by which melanoma cells can disseminate to regional lymph nodes and to distant sites and may be predictive of adverse outcomes. Although it can be detected on hematoxylin- and eosin-stained sections, sensitivity is markedly improved by immunohistochemistry for lymphatic endothelial cells. Multiple studies have reported a significant association between the presence of lymphatic invasion and sentinel lymph node metastasis and survival...

Background. The survival of patients with cutaneous malignant melanoma (MM) depends on multiple factors whose role is continuously updated, as the molecular mechanisms underlying the disease progression are understood. This study intended to assess whether the patient's gender and tumor location affect the disease outcome. Methods. Between 2008 and 2012, 155 patients with cutaneous MM underwent various types of surgeries in our clinic. Patients were staged according to the 2009 TNM classification. There were 90 women and 65 men...

Although it is a relatively rare disease, primarily found in the Caucasian population, uveal melanoma is the most common primary intraocular tumor in adults with a mean age-adjusted incidence of 5.1 cases per million per year. Tumors are located either in iris (4%), ciliary body (6%), or choroid (90%). The host susceptibility factors for uveal melanoma include fair skin, light eye color, inability to tan, ocular or oculodermal melanocytosis, cutaneous or iris or choroidal nevus, and BRCA1-associated protein 1 mutation...

Metastasis represents the end product of an elaborate biological process, which is determined by a complex interplay between metastatic tumour cells, host factors and homoeostatic mechanisms. Cutaneous melanoma can metastasize haematogenously or lymphogenously. The three predominant models that endeavour to explain the patterns of melanoma progression are the stepwise spread model, the simultaneous spread model and the model of differential spread. The time course to the development of metastases differs between the different metastatic routes...

Previous studies have found a link between high expression levels of the Deleted in Split hand/Split foot 1 (DSS1) gene and cancer progression. The aim of this study was to examine whether overexpression of DSS1 is a feature of melanoma and squamous cell carcinoma (SCC) and if any epigenetic modifications are involved. Evaluation of DSS1 expression profile indicated that the gene is overexpressed in 112/130 cutaneous melanomas (86.1%), 41/64 uveal melanomas (64.1%), 67/82 mucosal melanomas (81.7%), and 61/75 SCC samples (81...
