PURPOSE: Nestin, a member of the intermediate filament protein family, has been described as a putative cancer stem cell marker (CSC) in uveal melanoma and poor prognostic factor in a variety of tumours, including cutaneous melanoma. In this study, we examined the expression of nestin in primary (PUM) and metastatic uveal melanoma (MUM) samples, and correlated the findings with histological, clinical and survival data. METHODS: Nestin expression was assessed by immunohistochemistry in 141 PUM and 26 MUM samples; 11 PUM cases were matched with their corresponding metastases...

BACKGROUND Melanoma is an aggressive cancer with complex etiology and poor prognosis. Surgical resection is still the primary treatment of melanoma, but shows limited efficacy in late-stage patients. Additionally, reliable prognostic markers of skin melanoma patients are still lacking. Circulating tumor cells (CTCs) have shown promise in predicting prognosis of multiple cancers. Evaluating the prognostic value of CTC number in melanoma patients. MATERIAL AND METHODS CTCs were isolated by immunomagnetic capture from 7...

To compare BRAF V600E status of primary melanoma and brain metastases to assess for discordance by cross-sectional study, and to evaluate clinical implications on BRAF inhibitor therapy.Brain metastases are common in patients with advanced melanoma. Between 40% and 60% of melanomas demonstrate BRAF mutations, BRAF V600E being most common. Selective BRAF inhibitor therapy has shown improvement in outcome in patients with melanoma. It has been demonstrated that not all metastatic lesions carry the same BRAF mutation status as the primary, but the frequency in which discordance occurs remains unclear...

Patient age has been reported as a highly significant and strong predictor of the outcome in patients with cutaneous melanoma. The aim of the present study was to determine the clinical significance of patient age in Turkish patients with cutaneous melanoma. A total of 1,169 patients with pathologically proven cutaneous melanoma were enrolled. Age of patients was classified as young (<40 years), middle-aged (40-59 years) and old (≥60 years). The median age of the patients was 51 years (range, 16-104 years)...

Tumor thickness is the strongest predictor of outcome for clinically localized melanoma. Therefore, accurate assessment is critical for appropriate staging, reliable estimation of prognosis, and management. When melanoma extends alongside skin adnexal structures more deeply than the main tumor mass (periadnexal extension), it is currently unknown whether the prognosis is more accurately reflected by the deepest point of periadnexal tumor extension or the main tumor mass. This study sought to address this question...

Conjunctival melanoma (CM) is an exceptionally rare tumor, with a propensity for local and distant recurrence, with the lungs, skin, liver, and brain being the most common sites of metastasis. Recent progress in systemic treatments, with checkpoint inhibitors and targeted therapies blocking BRAF and MEK, has redefined the standard of care of advanced unresectable and metastatic melanoma. Although most trials did not include patients with conjunctival melanoma, its close molecular and genetic relationship to cutaneous melanoma might suggest a similar response to these novel agents...

Subungual melanoma (SUM) is an uncommon form of acral melanoma that arises within the nail matrix. The incidence for acral melanomas is similar worldwide, however, the proportion is higher in dark-skinned individuals. The subungual form represents approximately 2% of cutaneous non-sun-induced melanomas in the western world and up to 75% in Africans, 10% in Japanese, and 25% in the Chinese. No specific figures are available from the Indian subcontinent; however, the authors could trace three anecdotal case reports published over the last two decades...

We describe an uncommon case of a patient with a metastatic adenocarcinoma of ovarian origin presented as a gastric subepithelial tumor (SET) and that was diagnosed by endoscopic ultrasound fine-needle biopsy (EUS-FNB). Malignant gastric lesions are rarely metastatic and the primary tumor is mainly breast, lung, esophageal cancer or cutaneous melanoma. Gastric metastasis from ovarian cancer is unusual, presenting synchronously with the primary tumor but also several years later than the initial diagnosis. From an endoscopic point of view, gastric metastasis does not present specific features...

Cutaneous melanoma is a highly aggressive skin cancer whose treatment and prognosis are critically affected by the presence of metastasis. In this study, we address the following issue: which gene transcripts and what kind of interactions between them can allow to predict nonmetastatic from metastatic melanomas with a high level of accuracy? We carry out a meta-analysis on the first gene expression set of the Leeds melanoma cohort, as made available online on 11 May 2016 through the ArrayExpress platform with MicroArray Gene Expression number 4725...

We report the case of a 57-year-old man, who is hospitalized for the surgery of a gallbladder mass associated by an increase in fluorodeoxyglucose-activity on positron emission tomography/computed tomography scan. This is an incidental finding occurring during monitoring of a skin melanoma. A cholecystectomy is performed. Microscopic examination identified an infiltration of the gallbladder wall by a proliferation of atypical pigmented spindled melanocytes with numerous mitoses. The immunohistochemical analysis confirmed the melanocytic nature of this proliferation with the staining of HMB-45, S100 protein and Melan-A...

Extravascular migratory metastasis (EVMM), also known as pericytic mimicry or angiotropism, is a mechanism of angiocentric tumor spread that has been investigated mainly in cutaneous malignant melanoma where it has been associated with an increased risk of metastasis. In EVMM, the tumor cells spread along the external (ablumenal) aspect of vessels without breaching the endothelium, a process that is therefore distinct from the more widely recognized intraluminal invasion. Although EVMM has also been reported in a limited range of other tumor types, to our knowledge it has not been described in squamous cell carcinoma (SCC)...

The Dermatologic Oncology Group of Japan Clinical Oncology Group has started a randomized phase III trial to confirm the superiority of adjuvant therapy with locoregional interferon beta in overall survival over surgery alone for patients with pathological stage II/III cutaneous melanoma (JCOG1309). Patients in the interferon beta arm receive intra- or subcutaneous injections of interferon beta directly into the surgical site at a flat dose of 3 million units once per day. Treatment is repeated for 10 consecutive days every 8 weeks for a total of 3 courses during the induction phase, then 1-day injection every 4 weeks for 2...

BACKGROUND: TERT promoter mutations are frequent in melanoma. Here we analysed the concordance and prognostic impact of TERT mutation and telomerase reverse transcriptase (TERT) protein expression in a large melanoma series. METHODS: In 194 primary nodular melanomas with 72 matched loco-regional metastases, TERT promoter mutation status was assessed by Sanger sequencing and TERT protein expression by immunohistochemistry. RESULTS: TERT mutations were found in 68% of primary melanomas and 64% of metastases, and the mutation status was discordant between primary tumour and metastasis in 24% of the cases...

OBJECTIVE: Splenic metastases of melanoma are uncommon and generally part of a disseminated disease with a poor prognosis. In case of solitary visceral metastasis, surgical resection often remains an effective treatment. This case describes a long-term survival after splenectomy for a recurrent melanoma. METHODS: We present a 55-year-old female with a solitary splenic metastasis. Her medical history revealed a melanoma of the foot in 2007 and an in-transit metastasis in 2011...

In a previous work, we showed that CSF-470 vaccine plus bacillus Calmette-Guerin (BCG) and granulocyte macrophage colony-stimulating factor (GM-CSF) as adjuvants resulted in a significant benefit in the distant metastasis-free survival when comparing vaccinated vs. IFN-α2b-treated high-risk cutaneous melanoma patients in a Phase II study. Immune monitoring demonstrated an increase in anti-tumor innate and adaptive immunities of vaccinated patients, with a striking increase in IFN-γ secreting lymphocytes specific for melanoma antigens (Ags)...

Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal forms of cancer, and its incidence is rising worldwide. Although survival can be improved by surgical resection, when detected at an early stage, this type of cancer is usually asymptomatic, and disease becomes only apparent after metastasis. Adjuvant treatment does not improve survival, thus after surgery there is a lack of predictive and prognosis biomarkers to predict treatment response and survival. The mitogen-activated protein-kinase and phosphoinositide 3-kinase signalling pathways play a crucial role in cancer development and progression...
