Head and neck melanoma

Rebecca W Knackstedt, Rafael A Couto, Brian Gastman
BACKGROUND: Head and neck melanoma is associated with a high false negative (FN) sentinel lymph node biopsy (SLNB) rate. If techniques are developed that can decrease FN SLNBs, better prognostic information will be obtained, and it may be possible to improve overall survival as patients are assigned to the appropriate adjuvant management. Our group previously demonstrated that the combination of lymphoscintigraphy and indocyanine green (ICG) fluorescence-based technology was feasible for SLNB in primary melanoma...

Cutaneous polypoid melanoma is an uncommon subtype of malignant melanoma. The clinical behavior of this subtype has been described as aggressive. Tumors can be sessile or pedunculated. The typical patient is a younger adult. Authors have analyzed the case histories of patients with polypoid melanomas of the head and neck region treated at our clinic from 2001 to 2018. We identified 3 female patients with tumors of the neck and cheek. In contrast to other reports, all patients were older than 80-years of age...

Gout tophi around auricular area are common in old men. The differential diagnosis of papules or nodules on the ear includes tophaceous gout, rheumatoid nodules, basal or squamous cell cancer, melanoma, verruca vulgaris or actinic keratosis. The presence of the skin cancer, most commonly located on the head and neck, is often related to the long exposure of the skin to sunlight. Elderly patients are the predominant group of patients with skin malignancies. The aim of this study is to emphasize the importance of early cancer detection in elderly people and use of appropriate therapeutic options that take into account the special requirements of geriatric patients...

Neural precursor cell expressed developmentally downregulated 9 (NEDD9) is a component of the metastatic signatures of melanoma, breast cancer, glioblastoma, lung cancer and head and neck squamous cell carcinoma (HNSCC). Here we tested the efficacy of NEDD9's domains in stimulating matrix metalloproteinase (MMP) secretion and invadopodia formation in cells stably expressing various NEDD9 mutants. Replacement of the 13 YxxP motif substrate domain (SD) tyrosines and the C-terminal Y629 with phenylalanines (F14NEDD9) eliminated tyrosine phosphorylation, MMP9 secretion and loss of invadopodia formation...

BACKGROUND: There is a lack of consensus regarding optimal surgical excision margins for primary cutaneous melanoma > 1 mm in Breslow thickness (BT). A narrower surgical margin is expected to be associated with lower morbidity, improved quality of life (QoL), and reduced cost. We report the results of a pilot international study (MelMarT) comparing a 1 versus 2-cm surgical margin for patients with primary melanoma > 1 mm in BT. METHODS: This phase III, multicentre trial [NCT02385214] administered by the Australia & New Zealand Medical Trials Group (ANZMTG 03...

PURPOSE: Lymph node status is the single most important prognostic factor for patients with early-stage cutaneous melanoma. Sentinel lymph node biopsy (SLNB) has become the standard of care for intermediate depth melanomas. Modern SLNB implementation includes technetium-99 lymphoscintigraphy combined with local administration of a vital blue dye. However, sentinel lymph nodes may fail to localize in some cases and false-negative rates range from 0 to 34%. Here we demonstrate the feasibility of a new sentinel lymph node biopsy technique using indocyanine green (ICG) and the SPY Elite near-infrared imaging system...

Purpose: Skin cancers are the most common human malignancy with increasing incidence. Currently, surgery is standard of care treatment for non-melanoma skin cancers. However, brachytherapy is a growing modality in the management of skin cancers. Therefore, we aimed to assess the outcome of patients with non-melanoma skin cancers treated by high-dose-rate (HDR) brachytherapy with surface mold technique. Material and methods: In this prospective study, we recruited patients with basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) of the skin who were candidates for definitive or adjuvant brachytherapy during 2013-2014...

Worldwide melanoma incidence and mortality are increasing (1). Despite the ongoing research, advanced melanoma is still incurable; therefore, the most appropriate solution seems to be early detection combined with complete surgical excision (2). Since the diagnostic protocol of suspicious lesions includes a complete excision with safety margins (2), the problem of unnecessary scarring is significant. The real challenge in this case is to have a properly formulated diagnosis before acquiring a biopsy. Currently available non-invasive techniques are coherence tomography, digital dermoscopy, and reflectance confocal microscopy...

Progress in understanding tumor stromal biology has been constrained in part because cancer-associated fibroblasts (CAF) are a heterogeneous population with limited cell type-specific protein markers. Using RNA expression profiling, we identified the membrane protein leucine rich repeat containing 15 (LRRC15) as highly expressed in multiple solid tumor indications with limited normal tissue expression. LRRC15 was expressed on stromal fibroblasts in many solid tumors (e.g., breast, head and neck, lung, pancreatic) as well as directly on a subset of cancer cells of mesenchymal origin (e...

The recently published 4th Edition of the World Health Organization Classification of Head and Neck Tumors addresses the most relevant and updated aspects of tumor biology, including clinical presentation, histopathology, immunohistochemistry, and prognosis of head and neck tumors. The objective of the present study is to compare these updates to the 3rd edition of that book with regard to mucosal melanomas and to highlight the potential factors that differ those tumors from cutaneous melanomas. We observed progress in the understanding of oral and sinonasal mucosal melanomas, which also present themselves, in the molecular scope, differently form cutaneous melanomas...

Background: Mucosal melanoma is a rare form of melanoma presenting variably as sores or unexplained bleeding located mainly in the head and neck region, anorectal region or female genital tract. Mucosal melanoma is usually diagnosed at an advanced stage and is characterized by an aggressive behavior. Surgery represents the mainstay of treatment for early stage melanomas, but for advanced disease there have been until recently very limited treatment options. Ipilimumab, a human monoclonal antibody directed against the cytotoxic T lymphocyte antigen 4, was the first treatment modality to demonstrate survival benefit in advanced malignant melanoma...

PURPOSE: Hybrid image-guided surgery technologies such as combined radio- and fluorescence-guidance are increasingly gaining interest, but their added value still needs to be proven. In order to evaluate if and how fluorescence-guidance can help realize improvements beyond the current state-of-the-art in sentinel node (SN) biopsy procedures, use of the hybrid tracer indocyanine green (ICG)-99m Tc-nancolloid was evaluated in a large cohort of patients. PATIENTS AND METHODS: A prospective trial was conducted (n = 501 procedures) in a heterogeneous cohort of 495 patients with different malignancies (skin malignancies, oral cavity cancer, penile cancer, prostate cancer and vulva cancer)...

This cohort study assessed, in Italy, the overall pattern of risk for de novo malignancies following liver transplantation (LT). The study group included 2832 individuals who underwent LT between 1985 and 2014 in nine centres throughout all of Italy. Person-years (PYs) at cancer risk were computed from 30 days after LT to the date of cancer diagnosis, to the date of death, or to the end of follow-up. Excess cancer risk, as compared to the general population, was estimated using standardized incidence ratios (SIRs) and 95% confidence intervals (CIs)...
