Immunotherapy, especially checkpoint inhibitors such as anti-PD1 and anti-PDL1 antibodies, has changed the standard of care and the prognosis of melanoma, but also more recently of lung cancer, renal cancer and Hodgkin lymphoma. Results of preliminary studies in head and neck squamous cell carcinoma (HNSCC) as well as in less frequent tumors of the region, such as nasopharyngeal carcinoma and high grade salivary gland carcinoma, are also promising. Indeed, in a recent phase 3 study, the PD1 inhibitor nivolumab has recently demonstrated a significant improvement in overall survival for platin-resistant recurrent and/or metastatic HNSCC...

BACKGROUND: Mohs micrographic surgery (MMS) is an effective treatment for certain non-melanoma skin cancers. Optical coherence tomography (OCT) is a biomedical imaging modality that permits high-resolution imaging of the epidermis and dermis with the potential to detect both healthy tissue and tumour. OCT may also provide a means of detecting and differentiating between the various histological subtypes of basal cell carcinomas (BCC) in vivo. OBJECTIVE: The aim of this prospective ex vivo study was to evaluate the efficacy of OCT in recognising healthy and pathological margins of excised BCC lesions and detecting different BCC subtypes...

Cancer immunotherapy with monoclonal antibodies directed against regulatory pathways in T lymphocytes has been revolutionizing medical oncology, and the clinical success of monoclonal antibodies targeting either cytotoxic T lymphocyte antigen-4 (CTLA-4) or program death-1 (PD-1) in patients affected by melanoma, Hodgkin's lymphoma, Merkel cell carcinoma, and head and neck, bladder, renal cell or non-small cell lung cancer is way beyond the most optimistic expectation. However, immune checkpoint blockade (ICB) has failed to arrest progression in a consistent amount of patients affected by those tumors, and various histological types, including breast, colon and prostate cancer, are less sensitive to this therapeutic approach...

Nearly 20% of melanomas occur on the head and neck area(1) but only 2-5% arise on the scalp.(2) Several studies reported a worse prognosis of scalp melanoma compared to other body sites, being unclear the reason for this phenomenon.(3) Melanoma and non-melanoma skin cancer of the scalp are most frequent in bald men older than 65 years.

BACKGROUND: Detecting a more advanced stage of the primary melanoma after wide local excision and reconstruction can complicate patient counseling about prognosis, management of surgical margins, and indications for sentinel lymph node biopsy. OBJECTIVE: To identify the frequency of and risk factors associated with upstaging after wide local excision of primary melanoma. METHODS: Retrospective, single center, cross-sectional study of 1332 consecutive in situ to stage T4a melanomas treated with wide local excision...

T-box factors comprise an archaic family of evolutionary conserved transcription factors that regulate patterns of gene expression essential for embryonic development. The T-box transcription factor 3 (TBX3), a member of this family, is expressed in several tissues and plays critical roles in, among other structures, the heart, mammary gland and limbs and haploinsufficiency of the human TBX3 gene is the genetic basis for the autosomal dominant disorder, ulnar-mammary syndrome. Overexpression of TBX3 on the other hand has been linked to several cancers including melanoma, breast, pancreatic, liver, lung, head and neck, ovarian, bladder carcinomas and a number of sarcoma subtypes...

NADPH oxidase 4 (NOX4) is a redox active, membrane-associated protein that contributes to genomic instability, redox signaling, and radiation sensitivity in human cancers based on its capacity to generate H2O2 constitutively. Most studies of NOX4 in malignancy have focused on the evaluation of a small number of tumor cell lines and not on human tumor specimens themselves; furthermore, these studies have often employed immunological tools that have not been well characterized. To determine the prevalence of NOX4 expression across a broad range of solid tumors, we developed a novel monoclonal antibody that recognizes a specific extracellular region of the human NOX4 protein, and that does not cross-react with any of the other six members of the NOX gene family...

Pembrolizumab is a monoclonal antibody that targets the programmed death-1 receptor to induce immune-mediated clearance (CL) of tumor cells. Originally approved by the US Food and Drug Administration in 2014 for treating patients with unresectable or metastatic melanoma, pembrolizumab is now also used to treat patients with non-small-cell lung cancer, classical Hodgkin lymphoma, head and neck cancer, and urothelial cancer. This paper describes the recently identified feature of pembrolizumab pharmacokinetics, the time-dependent or time-varying CL...

The era of precision oncology is marked with prominent successes in the therapy of advanced soft tissue sarcomas, breast cancer, ovarian cancer and haematological neoplasms, among others. Moreover, recent trials of immune checkpoint inhibitors in melanoma, non-small cell lung carcinoma, and head and neck cancers have significantly influenced the therapeutic landscape by providing promising evidence for immunotherapy efficacy in the adjuvant setting in high-risk locoregional disease. To speed up the introduction of targeted therapy for cancer patients, novel phase II trials are being designed, and may likely form the basis for the 'landmark trials' of the future...

INTRODUCTION: Lentigo maligna (LM) is melanoma in situ on sun-damaged skin and presents diagnostic challenges due to overlapping features with benign pigmented lesions. Cosmetic treatments may be inadvertently performed on LM. The aim of this study is to estimate the prevalence of LM with prior cosmetic treatment, and evaluate surgical outcomes. STUDY DESIGN AND METHODS: Retrospective review of biopsy-proven LM presenting over a 10-year-period (2006-2015). Prior cosmetic treatment and biopsies were recorded...

Regulatory T cells (Tregs) are a barrier to anti-tumor immunity. Neuropilin-1 (Nrp1) is required to maintain intratumoral Treg stability and function but is dispensable for peripheral immune tolerance. Treg-restricted Nrp1 deletion results in profound tumor resistance due to Treg functional fragility. Thus, identifying the basis for Nrp1 dependency and the key drivers of Treg fragility could help to improve immunotherapy for human cancer. We show that a high percentage of intratumoral NRP1(+) Tregs correlates with poor prognosis in melanoma and head and neck squamous cell carcinoma...

During the last decade sentinel lymph nodes biopsy has become an essential part of primary surgical treatment in a number of malignancies including breast cancer, melanoma and head-and-neck malignancies. Dye or radioactive substances are injected at the primary tumor site, followed by pre-operative and intra-operative mapping. During surgery only positive lymph nodes are being dissected instead of a complete dissection of the lymphatic basin. The advantages of sentinel lymph nodes dissection are reducing the side effects of extensive lymph nodes dissection, while maintaining high detection rates and sensitivity in identifying cases with lymphatic tumor spread...

BACKGROUND: Mucosal melanomas are rare and highly aggressive tumors. Few studies evaluated mucosal melanomas of locations other than the head and neck region, and other than those of the Asian population. OBJECTIVES: The objective of this study was to analyze the clinical and histological features, as well as the mutational status of c-kit and b-raf gene of mucosal melanoma in any localization in a French series. METHODS: We investigated clinical (sex, age, performance status, survival, treatment of the patients and lack of pigmentation of the tumors) and histopathologic features (ulceration, Breslow's index, mitotic rate), as well as the mutational status of c-kit and b-raf of 86 mucosal melanomas diagnosed in 15 years in four French University Hospitals...

BACKGROUND: Merkel cell carcinoma (MCC) is a rare but aggressive cutaneous carcinoma. MCC involves typically dermis and although epidermotropism has been reported, MCC strictly intraepidermal or in situ (MCCIS) is exceedingly rare. Most of the cases of MCCIS described so far have associated other lesions, such as squamous or basal cell carcinoma, actinic keratosis, etc. Herein, we describe three patients with MCC strictly in situ, without a dermal component. METHODS: Our patients were elderly, two of the lesions involved the head and neck area and one was on a finger...

BACKGROUND AND OBJECTIVES: For patients with cutaneous melanoma, primary tumors located in the head and neck is associated with poor outcomes. The reason for this difference and whether it is applicable to all locations within the head and neck remains unclear. We hypothesized that scalp melanoma is uniquely distinguished from other anatomic sites and is independently responsible for the poor prognosis of head and neck melanoma. METHODS: Query and analysis of a prospectively maintained melanoma database of all patients treated for primary cutaneous melanoma from 1971 to 2010...

The aim of this study was to determine whether l-methyl-[(11)C]-methionine (MET) positron emission tomography (PET) allows the prediction of outcomes in patients with head and neck mucosal malignant melanoma treated with carbon ion radiation therapy (CIRT). This was a retrospective cohort study involving 85 patients who underwent a MET-PET or MET-PET/computed tomography (CT) examination before and after CIRT. MET uptake in the tumour was evaluated semi-quantitatively using the tumour-to-normal tissue ratio (TNR)...

PURPOSE: To present the clinical features of patients with parotid gland metastasis, and compare the results with previously published series. Most of the relevant literature arises from case reports, while there are only few series reported, as secondary neoplastic lesions of the parotid gland are uncommon. METHODS: The medical records of patients with parotid gland metastasis, treated at the ENT Department of the University Hospital of Ferrara, between January 1st 1965 and December 31th 2014, were retrospectively reviewed...
