PD-L1 expression in the tumor immune microenvironment is recognized as both a prognostic and predictive biomarker in patients with cutaneous melanoma, a finding closely related to its adaptive (IFN-γ-mediated) mechanism of expression. Approximately 35% of cutaneous melanomas express PD-L1, however, the expression patterns, levels, and prevalence in rarer melanoma subtypes are not well described. We performed immunohistochemistry for PD-L1 and CD8 on 200 formalin-fixed paraffin-embedded specimens from patients with acral (n=16), mucosal (n=36), uveal (n=103), and chronic sun-damaged (CSD) (n=45) melanomas (24 lentigo maligna, 13 'mixed' desmoplastic, and 8 'pure' desmoplastic melanomas)...

Neurotropic cutaneous melanoma is a rare melanoma subtype that invades nerves and is often associated with desmoplastic melanoma. Limited data suggest that it has a greater propensity to recur locally, but it is unknown whether its behavior differs from that of other melanoma subtypes, including desmoplastic melanoma. We investigated clinicopathological predictors of outcome in a cohort of 671 patients with neurotropic melanoma to develop evidence-based management recommendations. Patients with primary neurotropic melanoma diagnosed from 1985 to 2013 were identified from the Melanoma Institute Australia database, along with a control cohort of 718 non-neurotropic melanoma patients...

BACKGROUND: Reduced-dose nivolumab in combination with standard-dose ipilimumab improves objective response and progression-free survival compared with standard-dose ipilimumab alone, but increases toxicity. We assessed the safety and anti-tumour activity of standard-dose pembrolizumab in combination with reduced-dose ipilimumab. METHODS: In this open-label, phase 1b trial, we recruited patients from 12 medical centres in Australia, New Zealand, and the USA. Eligible patients were aged at least 18 years, had advanced melanoma, had an Eastern Coooperative Oncology Group performance status of 0 or 1, had measurable disease according to the Response Evaluation Criteria in Solid Tumors (RECIST) version 1...

A sentinel lymph node biopsy is a surgical staging procedure performed for patients with primary cutaneous melanoma who are clinically lymph-node negative to determine whether there is low volume nodal metastasis in the draining lymph node field. A systematic review was recently performed to update the Australian clinical practice guidelines for the diagnosis and management of melanoma, addressing the question, 'When is a sentinel lymph node biopsy indicated?' This article discusses the findings of the systematic review and the evidence base for the updated guidelines...

REVIEW

Worldwide, sentinel node (SN) biopsy for accurate staging is now part of the standard work-up of patients with melanomas ≥1.0 mm Breslow thickness, as it is for staging patients with breast cancer. Nuclear medicine imaging and surgical techniques have evolved to such a degree that a SN can be identified and removed in virtually every patient. Nevertheless, some opposition to a routine SN biopsy remains, perhaps due to a failure to appreciate the serious implications of incomplete or inaccurate staging. Guided by a critical appraisal of the available evidence, this review elucidates the definition of an SN, discusses the sensitivity and specificity of the information it provides, emphasises that it is a minor staging procedure that can lead to improved survival when followed by appropriate therapy, and explains the necessarily unconventional and complex design of the only randomised trial that addresses this subject...

BACKGROUND: Hypothetically, delay between melanoma diagnosis and SLNB could affect outcomes, either adversely by allowing growth and dissemination of metastases, or beneficially by allowing development of an anti-melanoma immune response. Available data are conflicting about the effect of SLNB delay on patient survival. Our objective was to determine whether delay between initial diagnosis and SLNB affects outcomes in patients with cutaneous melanoma. STUDY DESIGN: We performed query and analysis of a large prospectively maintained database of patients with primary cutaneous melanomas undergoing SLNB...

Imaging plays a critical role in the current multi-disciplinary management of patients with melanoma. It is used for primary disease staging, surgical planning, and surveillance in high-risk patients, and for monitoring the effects of systemic or loco-regional therapies. Several different imaging modalities have been utilised in the past. Contemporary imaging practises vary geographically depending on clinical guidelines, physician preferences, availability and cost. Targeted therapies and immunotherapies have revolutionised the treatment of patients with metastatic melanoma over the last few years...

BACKGROUND: Sentinel-lymph-node biopsy is associated with increased melanoma-specific survival (i.e., survival until death from melanoma) among patients with node-positive intermediate-thickness melanomas (1.2 to 3.5 mm). The value of completion lymph-node dissection for patients with sentinel-node metastases is not clear. METHODS: In an international trial, we randomly assigned patients with sentinel-node metastases detected by means of standard pathological assessment or a multimarker molecular assay to immediate completion lymph-node dissection (dissection group) or nodal observation with ultrasonography (observation group)...

BACKGROUND: Standardization of the clinical management of melanoma through the formulation of national guidelines, based on interpretation of the existing evidence and consensus expert opinion, seeks to improve quality of care; however, adherence to national guidelines has not been well studied. METHODS: A population-based, cross-sectional study of the clinical management of all patients with newly notified primary melanomas in the state of New South Wales, Australia, during 2006/2007 was conducted using cancer registry identification and questionnaires completed by treating physicians...

The use of staging imaging in melanoma patients with a positive sentinel lymph node (SLN) has been reported to be of limited value. Improved accuracy resulting from the development of time-of-flight positron emission tomography (PET) and ongoing image quality improvement of computed tomography (CT) may challenge this statement. Our retrospective study assessed the clinical value of routine staging CT and PET/CT imaging in a recent cohort of asymptomatic SLN-positive patients. Between January 2011 and April 2014, 143 patients with a positive SLN were routinely staged using CT of various parts of the body or whole-body PET/CT...

Melanoma of the skin is a common cancer only in Europeans, whereas it arises in internal body surfaces (mucosal sites) and on the hands and feet (acral sites) in people throughout the world. Here we report analysis of whole-genome sequences from cutaneous, acral and mucosal subtypes of melanoma. The heavily mutated landscape of coding and non-coding mutations in cutaneous melanoma resolved novel signatures of mutagenesis attributable to ultraviolet radiation. However, acral and mucosal melanomas were dominated by structural changes and mutation signatures of unknown aetiology, not previously identified in melanoma...

Genome wide association studies (GWAS) have mapped multiple independent cancer susceptibility loci to chr5p15.33. Here, we show that fine-mapping of pancreatic and testicular cancer GWAS within one of these loci (Region 2 in CLPTM1L) focuses the signal to nine highly correlated SNPs. Of these, rs36115365-C associated with increased pancreatic and testicular but decreased lung cancer and melanoma risk, and exhibited preferred protein-binding and enhanced regulatory activity. Transcriptional gene silencing of this regulatory element repressed TERT expression in an allele-specific manner...

Purpose Standard cancer staging and prognostic estimates are determined at the time of the patient's initial disease presentation. Conditional survival is an alternative, dynamic assessment from follow-up time points after the initial disease diagnosis and is based on the condition of survivorship. Estimates of conditional survival can provide critical prognostic information for patients and clinicians, guide subsequent cancer follow-up schedules, and influence decisions regarding treatments. The current study presents conditional survival estimates developed from a cohort of 4,540 patients diagnosed with stage III melanoma treated at a single institution...

We present a new foundational role for CXCR3(+) monocytes/macrophages in the process of tumor engraftment in the lung. CXCR3 is associated with monocytic and lymphocytic infiltration of inflamed or tumor-bearing lung. Although the requirement for tumor-expressed CXCR3 in metastatic engraftment has been demonstrated, the role of monocyte-expressed CXCR3 had not been appreciated. In a murine model of metastatic-like melanoma, engraftment was coordinate with CXCR3(+) monocyte/macrophage accumulation in the lungs and was sensitive to pharmacologic inhibition of CXCR3 signaling...

Tobacco smoking is a strong risk factor for cancer, but associations with basal cell carcinomas (BCC) and squamous cell carcinomas (SCC) of the skin have been inconsistent. We prospectively investigated the associations between cigarette smoking and 3-year incidence of first primary BCC or SCC in the QSkin cohort (n=43765). Smoking history was self-reported at baseline; newly diagnosed and surgically treated BCCs and SCCs were ascertained through linkage to the national health insurance scheme and verified by histopathology reports...

REOLYSIN(®) (pelareorep) is an investigational new drug, consisting of a live, replication-competent, Reovirus Type 3 Dearing strain in a proprietary formulation. Several preclinical and clinical trials with REOLYSIN(®) on a wide range of cancer indications have demonstrated antineoplastic activity on cells with activated RAS-signaling pathway. Furthermore, long-term survival benefits were evident in post-treatment patients indicating a potential antitumor immune response triggered by REOLYSIN(®). Numerous mono and/or combination therapy studies with the agent showed a consistent safety profile...
