Malignant melanoma is the deadliest form of all skin cancers. Itraconazole, a commonly used systemic antifungal drug, has been tested for its anti-tumor effects on basal cell carcinoma, prostate cancer, and non-small cell lung cancer. Whether itraconazole has any specific anti-tumor effect on melanoma remains unknown. However, the goal of this study is to investigate the effect of itraconazole on melanoma and to reveal some details of its underlying mechanism. In the in vivo xenograft mouse model, we find that itraconazole can inhibit melanoma growth and extend the survival of melanoma xenograft mice, compared to non-itraconazole-treated mice...

PurposeSuspicious neoplastic conjunctival lesions often require wide excision with tumour-free margins, leaving significant conjunctival defects requiring reconstruction. In this study we report the results of using fresh frozen amniotic membrane grafts (AMG) after wide excision of potentially malignant lesions.MethodsRetrospective review of 53 patients; between January 2011 and April 2014. Conjunctival lesions were excised with a non-touch technique (2 mm margin) and sent for histopathological analysis. The surgical margins were treated with cryotherapy and a fresh frozen AMG was used to cover the defect...

BACKGROUND: The function of the tumor suppressor gene RASSF1A in cancer cells has been detailed in many studies. However, due to the methylation of its promoter, the expression of RASSF1A is missing in most cancers. In the literature, we found that the conclusion regarding the relationship between RASSF1A gene promoter methylation and the susceptibility and prognosis of melanoma was not unified. This study adopts the use of a meta-analysis and bioinformatics to explore the relationship between RASSF1A gene promoter methylation and the susceptibility and prognosis of melanoma...

The presence of psychological distress has a negative impact not only on cancer patients' quality of life but also on the course of the disease, with slower recovery and increased morbidity. These issues are of particular importance in melanoma patients (MP), who remain at risk of disease progression for many years after diagnosis. This study aimed to investigate psychological distress, coping strategies, and their possible relationships with demographic-clinical features in patients with early-stage melanoma in follow-up...

The prognosis of patients with gastrointestinal (GI) melanoma metastases is poor. Surgery renders select patients disease free and/or palliates symptoms. We reviewed our single-institution experience of resection with GI melanoma metastases. A retrospective review was performed on patients who underwent surgery for GI melanoma metastases from 2007 to 2013. Fifty-four patients were identified and separated based on completeness of resection into curative 13 (24%) and palliative 41 (75.9%) groups. Thiry-six (63...

Uveal melanoma (UM) is the most common intraocular malignancy and arises from melanocytes in the iris, ciliary body, or choroid. Early diagnosis and local treatment is crucial, as survival correlates with primary tumor size. However, approximately 50% of patients will develop metastatic disease with 6-12 months' survival from metastatic diagnosis. Genomic analyses have led to the development of gene-expression profiles that effectively predict metastatic progression; unfortunately, no adjuvant therapy has been shown to prolong survival to date...

BACKGROUND: The latest AJCC classification has included the number of mitoses as a factor for upstaging thin melanomas. Meanwhile, while dermoscopy has often been used to predict melanoma thickness, its value in predicting number of mitoses remains unknown. OBJECTIVE: Our aim is to evaluate the correlation between dermoscopic features and the presence of mitoses in a consecutive cohort of thin melanomas. METHODS: A case control study has been performed to identify specific dermoscopic parameters that could differentiate thin melanomas with 1 or more mitoses per mm2 from those without mitoses...

Glycaemic index (GI) and glycaemic load (GL) are indicators of dietary carbohydrate quantity and quality and have been associated with increased risk of certain cancers and type 2 diabetes. Insulin resistance has been associated with increased melanoma risk. However, GI and GL have not been investigated for melanoma. We present the first study to examine the possible association of GI and GL with melanoma risk. We carried out a population-based, case-control study involving 380 incident cases of cutaneous melanoma and 719 age- and sex-matched controls in a northern Italian region...

REVIEW
Imanol Arozarena, Claudia Wellbrock
Melanoma is a skin cancer notorious for its metastatic potential. As an initial step of the metastatic cascade melanoma cells part from the primary tumour and invade the surrounding tissue, which is crucial for their dissemination and the formation of distant secondary tumours. Over the last two decades our understanding of both, general and melanoma specific mechanisms of invasion has significantly improved, but to date no efficient therapeutic strategy tackling the invasive properties of melanoma cells has reached the clinic...

PURPOSE: Invariant NKT cells (iNKT) are innate-like CD1d-restricted T cells with immunoregulatory activity in diseases including cancer. iNKT from advanced cancer patients can have reversible defects including IFNγ production, and iNKT IFNγ production may stratify for survival. Previous clinical trials using iNKT cell activating ligand α-galactosylceramide have shown responses. Therefore, a phase 1 clinical trial was performed of autologous in vitro expanded iNKT cells in stage IIIB-IV melanoma...

Deregulation of p16INK4A is a critical event in melanoma susceptibility and progression. It is generally assumed that the major effect of loss of p16 function is mediated through the CDK-cyclin pathway via its influence on the pocket protein (PP) pRb. However, there are also two other PPs, p107 and p130, which, when phosphorylated by CDK-cyclin complexes, play a role in permitting cell progression. Cohorts of mice carrying melanocyte-specific knockouts (KOs) of various combinations of the three PPs were generated...

Tumor-necrosis-factor-alpha (TNFa) is an innate cytokine involved in regulating inflammation, immunity, tumorigenesis, and apoptosis. TNFa inhibitors became a powerful tool in the treatment of auto-immune inflammatory diseases such as Crohn's disease, ulcerative colitis, rheumatoid arthritis and psoriasis. Known side effects of TNFa inhibitors range from infections to malignancies [1]. We report a male patient who was in 1998 at age 36 diagnosed with amelanotic melanoma of the leg, Breslow thickness 11.0 mm, no ulceration...

Digital dermoscopy (DD) follow up is a useful strategy for monitoring patients at high risk of melanoma. Reflectance confocal microscopy (RCM) is a valuable second-level examination after dermoscopy for the evaluation of difficult to diagnose lesions. The aim of this study was to assess the value of RCM in routine DD monitoring of patients at high risk of melanoma. In this prospective study, performed over 22 months, changing melanocytic lesions were detected by DD and excised. RCM imaging was performed before surgical excision of all the lesions, and histopathology used as the gold standard diagnostic test...

Estimating the population attributable fraction (PAF) of melanomas due to sun exposure is challenging as there are no unexposed population nor reliable exposure data. In high incidence countries, a historic cohort of the South Thames cancer registry was used as a minimally exposed population using the formula PAF = (observed incidence-incidence in minimally exposure)/observed incidence. In this study we apply this method, constructing a minimally exposed cohort for Colombia and also using the historical South Thames data, using melanoma incidence data from the population-based cancer registry of Cali, Colombia for the period 1967-2012...

We performed exome sequencing of 77 melanocytic specimens composed of Spitz nevi (n=29), Spitzoid melanomas (n=27), and benign melanocytic nevi (n=21), and compared the results with published melanoma sequencing data. Our study highlights the prominent similarity between Spitzoid and conventional melanomas with similar copy number changes and high and equal numbers of ultraviolet-induced coding mutations affecting similar driver genes. Mutations in MEN1, PRKAR1A, and DNMT3A in Spitzoid melanomas may indicate involvement of the protein kinase A pathway, or a role of DNA methylation in the disease...

Human ErbB-2 (Her-2) is a critical target for cancer immunotherapy, and its over-expression can promote cancer migration and invasion. Compared with passive antibody therapy, vaccination treatment is more effective in the prevention of cancer recurrence. BALB-neuT mouse is a spontaneous metastasis tumor model used for testing the anti-tumor metastatic effect of rat ErbB-2 (neu) vaccine. However, no spontaneous metastasis tumor model used for evaluating Her-2 vaccine has been developed. In the current study, we attempted to use murine melanoma cell lines to establish a stable spontaneous metastasis tumor model for Her-2 vaccines...
