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...

OBJECTIVE: To establish Australian population-based incidence trends for mucosal melanoma of the head and neck. METHODS: Cases between 1985 and 2009 were identified in the Australian Cancer Database. Age-standardised incidence trends were established, including subgroup stratification by sex and site. RESULTS: A continuously progressive increase in incidence was evident in the 353 cases identified over the 25-year study period. This was particularly evident in sinonasal mucosal melanoma in men, despite the overall incidence remaining higher in women...

Head and neck mucosal melanoma (HNMuM), which occurs mostly in the sinonasal and oral cavity, constitutes less than 1% of all malignant melanomas. Treatment options fail to improve the prognosis of this aggressive tumour that has low overall survival rates. Thus, development of new targeted therapies is essential. Unfortunately, limited data exist regarding their molecular profile. BRAF, NRAS, KIT, TERT and GNAQ/GNA11 oncogene mutations were investigated in 42 HNMuMs (28 sinonasal, 13 oral, 1 nasopharyngeal)...

BACKGROUND: BRAF(V600) , NRAS, TP53, and BRAF(Non-V600) are among the most common mutations detected in non-acral cutaneous melanoma patients. Although several studies have identified clinical and pathological features associated with BRAF(V600) and NRAS mutations, limited data are available regarding the correlates and significance of TP53 and BRAF(Non-V600) mutations. METHODS: This study analyzed the patient demographics, primary tumor features, and clinical outcomes of a large cohort of non-acral cutaneous melanoma patients who had undergone clinically indicated molecular testing (n = 926)...

BACKGROUND: Alcohol consumption is associated with increased risk of numerous cancers, but existing evidence for an association with melanoma is equivocal. No study has evaluated the association with different anatomic locations of melanoma. METHODS: We used data from three large prospective cohort studies to investigate whether alcohol intake was associated with risk of melanoma. Alcohol intake was assessed repeatedly by food-frequency questionnaires. A Cox proportional hazards model was used to calculate multivariate-adjusted hazard ratios (HRs)...

BACKGROUND: When encountering solid pancreatic lesions, nonpancreatic primary metastases are rare and differentiating a metastasis from a primary neoplastic lesion is challenging. The clinical presentation and radiologic features can be similar and the possibility of a pancreatic metastasis should be considered when the patient refers to a history of a different primary cancer. Endoscopic ultrasound offers a key anatomical advantage in accessing the pancreas and endoscopic ultrasound-guided fine-needle aspiration has become the gold standard method for diagnosing pancreatic lesions...

BACKGROUND: Immunotherapy targeting the checkpoint PD1 (programmed cell death protein 1) or PDL1 (programmed death ligand 1) has led to advances in the treatment of melanoma and non-small cell lung cancer (NSCLC). The use of such therapies has also been introduced into the treatment of other malignancies, including head and neck cancer. The combined effects of checkpoint inhibitors and anti-PD1(L1) antibodies and radiation therapy have not yet been sufficiently investigated. CASE PRESENTATION: We report a case of locally relapsed non-resectable oral cavity squamous cell carcinoma, with excellent local control after pembrolizumab (MK3475) followed by radiotherapy...

BACKGROUND: Isosulfan blue dye peripheral injection is used in preoperative sentinel lymph node (SLN) identification alone or, to increase sensitivity, in conjunction with radiocolloid mapping. However, isosulfan blue dye has certain drawbacks and limitations. OBJECTIVE: This study assesses the authors' experience of SLN biopsy using only radiocolloid tracer. MATERIALS AND METHODS: Between 2000 and 2008, 218 patients underwent SLN biopsy with radiocolloid mapping, preoperative localization by lymphoscintigraphy and intraoperative confirmation by gamma probe in primary malignant cutaneous melanoma...

Primary mucosal melanomas of the head and neck are rare and aggressive tumours that arise in the nasal cavity, paranasal sinuses and more rarely, in the oral cavity. The current treatment options include radical surgical resection with adjuvant external beam radiotherapy being offered in high risk patients. Although the latter can improve regional control, it does not reduce overall survival. Elective neck dissection is recommended for nodular oral mucosal melanoma but its role in the clinically node negative neck is controversial...

INTRODUCTION: Sentinel lymph node (SLN) biopsy is widely accepted as an important part of staging cutaneous malignant melanoma. Hybrid single photon emission computed tomography and computed tomography (SPECT/CT) may identify additional SLN and provide important information to the surgeon performing SLN biopsy. We report our experience at a major referral centre for melanoma surgery. METHODS: Retrospective case series of pre-operative sentinel node lymphoscintigraphy for primary melanoma over a consecutive 12-month period...

Mucosal melanomas of the head and neck (MMHN) are aggressive tumors with poor prognosis, different opposed to cutaneous melanoma. In this study, we characterized primary mucosal malignant melanoma for the expression of Kallikrein-related peptidase 6 (KLK6), a member of the KLK family with relevance to the malignant phenotype in various cancer types including cutaneous melanoma. Paraffin-embedded MMHN of 22 patients were stained immunohistochemically for KLK6 and results were correlated with clinical and pathological data...

Squamous cell carcinoma (SCC) is the second commonest type of skin cancer. Moreover, about 90% of head and neck cancers are SCCs. SCCs develop at a significantly higher rate under chronic immunosuppressive conditions, implicating a role of immune surveillance in controlling SCCs. It remains largely unknown how SCCs evade immune recognition. Here, we established a mouse model by injecting tumor cells derived from primary SCCs harboring KrasG12D mutation and Smad4 deletion into wild-type (wt) or CD8-/- recipients...

Cutaneous T-cell lymphoma (CTCL) is the most frequently encountered type of skin lymphoma in humans. CTCL encompasses multiple variants, but the most common types are mycosis fungoides (MF) and Sezary syndrome (SS). While most cases of MF run a mild course over a period of many years, other subtypes of CTCL are very aggressive. The rapidly expanding fields of proteomics and genomics have not only helped increase knowledge concerning the carcinogenesis and tumor biology of CTCL but also led to the discovery of novel markers for targeted therapy...

BACKGROUND: Previous studies have shown an increase in the incidence of cutaneous melanoma (CM) in Estonia, but also poor survival in international comparisons, with a significant survival gap between the sexes. The aim of this study was to analyze the time trends in CM incidence and relative survival by age, TNM stage and anatomical subsite among men and women in Estonia. MATERIALS AND METHODS: Data from the Estonian Cancer Registry were used to calculate age-standardized (World) and age-specific incidence of CM in 1995-2013, and five-year relative survival ratios (RSR) for cases diagnosed in 1995-2012 and followed through in 2014...

There are very few data available regarding the pattern of first metastases in resected mucosal melanomas (MMs) as well as the response of advanced MM to cytotoxic therapy. A retrospective, single-institution cohort was assembled of all patients with advanced/unresectable MM between 1995 and 2012 who had received systemic therapy with available imaging (N=81). Responses to first-line and second-line systemic therapy were assessed using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. The relationship between response, overall survival, and clinical covariates was investigated using Cox proportional hazards regression...
