Long-term results with linear accelerator LINAC-based stereotactic radiosurgery for intraocular uveal malignant melanoma were assessed. A retrospective study was carried out of patients with uveal melanoma after a 1-day session stereotactic radiosurgery at LINAC in Slovakia. In the period 2001-2015, a group of 150 patients with uveal melanoma (139 choroidal melanoma, 11 ciliary body melanoma) was treated. The median tumor volume at baseline was 0.5 cm (with range from 0.2 to 1.6 cm). Tumors ranged in size from 2...

Approximately 25% of melanoma patients with locoregional metastases are nonresponsive to new molecular target therapy and immunotherapy. When metastases are located in the pelvis, melphalan hypoxic perfusion can be an optional treatment. Because methylation of MGMT promoter increases the efficacy of alkylating agents, studies on melanoma outcome of patients treated with melphalan regional chemotherapy should consider this epigenetic change. This study aims to evaluate whether the survival of stage III melanoma patients treated with melphalan regional chemotherapy may be correlated with MGMT methylation status...

Melanoma remains the leading cause of skin cancer-related deaths. Surgical resection and adjuvant therapies can result in disease-free intervals for stage III and stage IV disease; however, recurrence is common. Understanding microRNA (miR) dynamics following surgical resection of melanomas is critical to accurately interpret miR changes suggestive of melanoma recurrence. Plasma of 6 patients with stage III (n = 2) and stage IV (n = 4) melanoma was evaluated using the NanoString platform to determine pre- and postsurgical miR expression profiles, enabling analysis of more than 800 miRs simultaneously in 12 samples...

INTRODUCTION: Melanoma-associated antigen 1 (MAGE1) expression in normal tissues is restricted to the testes, whilst being over-expressed in a number of human cancers. This feature of MAGE1 makes it a promising cancer biomarker. This study aimed to determine the expression of MAGE1 in esophageal squamous cell carcinoma (SCC) and its relationship with clinicopathological factors. METHODS: This is a cross-sectional study conducted on pretreatment endoscopic tissue specimens of 43 patients with non-metastatic esophageal SCC, admitted to Omid Hospital, Mashhad, Iran, between 2011 and 2013...

Vaginal melanoma is a rare tumor, accounting for <1% of all melanomas and ~1-5% of all vaginal malignant tumors. The prognosis of vaginal melanoma is extremely poor, as it is often resistant to chemotherapy and radiotherapy, and metastases may develop in the early stages of the disease. The present study investigated 5 patients with vaginal melanoma treated at the Department of Gynecology of Osaka City University Hospital (Osaka, Japan) between October, 2000 and April, 2014. All the cases presented with abnormal genital bleeding as the main complaint...

A 57-year-old man presented with a 4-month history of worsening symptoms of oesophageal obstruction. The physical examination was unremarkable. An oesophagogastroduodenoscopy revealed an exophytic tumour in the distal oesophagus. A biopsy demonstrated malignant melanoma. Staging of the melanoma showed disseminated lymph node and bony-spine metastases. He had no prior history of cutaneous or ocular melanoma. Following full multidisciplinary team input, he was palliated with a metal mesh stent and immunotherapy...

High TIMP1 expression is associated with poor prognosis in melanoma, where it can bind to CD63 and β1 integrin, inducing PI3-kinase pathway and cell survival. Phosphatidylinositol (3,4,5)-trisphosphate (PIP3), generated under phosphatidylinositol-3-kinase (PI3K) activation, enables the recruitment and activation of protein kinase B (PKB/AKT) and phosphoinositide-dependent kinase 1 (PDK1) at the membrane, resulting in the phosphorylation of a host of other proteins. Using a melanoma progression model, we evaluated the impact of Timp1 and AKT silencing, as well as PI3K, PDK1, and protein kinase C (PKC) inhibitors on aggressiveness characteristics...

Systemic adjuvant therapy for surgically resected cutaneous melanoma that is at high risk for disease recurrence and death targets residual micrometastatic disease which is the source of future local or distant relapse. Interferon-alfa (IFNα) has been the most extensively studied in regimens that varied by dosage, route of administration, formulation, and duration of therapy. Most regimens have demonstrated improvements in relapse-free survival (RFS), while the regimen administered at high dosage (HDI) showed improvements in overall survival (OS) in two out of three RCTs...

Laboratory of genetics and physiology 2 (LGP2) is a key component of RIG-I-like receptors (RLRs). However, the lack of the caspase recruitment domains (CARDs) results in its controversial functional performance as a negative or positive regulator in antiviral responses. Especially, no sufficient evidence uncovers the functional mechanisms of LGP2 in RLR signaling pathways in teleost. Here, negative regulation mechanism of LGP2 in certain situations in retinoic acid-inducible gene I (RIG-I) and melanoma differentiation-associated gene 5 (MDA5)-mediated antiviral responses was identified in Ctenopharyngodon idella kidney cells...

Anti-PD-1 therapy has improved clinical outcomes in advanced melanoma, but most patients experience intrinsic resistance. Responding patients can develop acquired resistance to anti-PD-1. We retrospectively reviewed 488 patients treated with anti-PD-1 from three academic centers and identified 36 patients with acquired resistance, defined as disease progression following objective response. The incidence, timing, disease sites, post-progression survival (PPS), and outcomes were evaluated descriptively. The acquired resistance cohort consisted of 67% with more than 1 feature of poor prognosis (stage M1c, elevated LDH, or brain metastasis), and 67% had previously received ipilimumab...

BACKGROUND: Uveal melanoma is a rare tumour with no established treatments once metastases develop. Although a variety of immune-based therapies have shown efficacy in metastatic cutaneous melanoma, their use in ocular variants has been disappointing. Recently, adoptive T-cell therapy has shown salvage responses in multiple refractory solid tumours. Thus, we sought to determine if adoptive transfer of autologous tumour-infiltrating lymphocytes (TILs) could mediate regression of metastatic uveal melanoma...

OBJECTIVE: Melanoma is a highly aggressive tumour, and treatment efficacy depends on the stage of the tumour. Early stage cutaneous melanoma is efficiently treated by surgical excision. In contrast, late-stage melanoma requires chemotherapy with dacarbazine (DTIC). Unfortunately, advanced melanoma can often be resistant to DTIC. The mechanisms of anti-melanoma effects of DTIC are still poorly understood, which hinders development of more potent therapies. In this study, we examined the effects of DTIC on growth inhibition of FEMX-1 melanoma cell line, expression of apoptosis-related proteins, and expression of micro (mi)RNA-200 (miRNA-200a, miRNA-200b, miRNA-200c, and miRNA-141)...
