Skin cancer/melanoma

C Franklin, E Livingstone, A Roesch, B Schilling, D Schadendorf
Malignant melanoma contributes the majority of skin cancer related deaths and shows an increasing incidence in the past years. Despite all efforts of early diagnosis, metastatic melanoma still has a poor prognosis and remains a challenge for treating physicians. In recent years, improved knowledge of the pathophysiology and a better understanding of the role of the immune system in tumour control have led to the development and approval of several immunotherapies. Monoclonal antibodies against different immune checkpoints have been revolutionizing the treatment of metastatic and unresectable melanoma...

Skin cancer is the most common of human cancers and outnumbers all other types of cancer combined in the USA by over threefold. The majority of non-melanoma skin cancers are easily treated with surgery or locally destructive techniques performed under local anesthesia in the cost-effective outpatient setting. However, there is a subset of "high-risk" cases that prove challenging in terms of morbidity, mortality, adjuvant treatment required, as well as overall cost to the health care system. In our opinion, the term "high risk" when applied to skin cancer can mean one of three things: a high-risk tumor with aggressive histologic and/or clinical features with an elevated risk for local recurrence or regional/distant metastasis, a high-risk patient with the ongoing development of multiple skin cancers, and a high-risk patient based on immunosuppression...

Melanoma is the most aggressive skin-cancer, showing high mortality at advanced stages. Platelet Derived Growth Factor Receptor-alpha (PDGFR-alpha) potently inhibits melanoma- and endothelium-proliferation and its expression is significantly reduced in melanoma-biopsies, suggesting that melanoma progression eliminates cells expressing PDGFR-alpha. In the present study transient overexpression of PDGFR-alpha in endothelial (HUVEC) and melanoma (SKMel-28, A375, Preyer) human-cells shows strong anti-proliferative effects, with profound transcriptome and miRNome deregulation...

BACKGROUND: Some patients with chronic myeloid leukemia (CML) have a history of previous malignancies. To the authors' knowledge, outcomes for CML diagnosed in these patients have not been well described. The current study was conducted to determine the outcome of patients with CML and a history of prior malignancies. METHODS: The current study included patients who were enrolled in clinical trials of tyrosine kinase inhibitors as initial therapy for CML in chronic phase from July 2000 to January 2014...

BRAF inhibitors (vemurafenib and dabrafenib) are nowadays commonly prescribed in BRAF-mutant metastatic melanoma and allow improvement of the overall survival and progression-free survival. They are, however, accompanied by many adverse effects which mainly affect the skin. We observed on computed tomographic scans in three different patients after 3 months of treatment, the onset of osteosclerotic lesions. In parallel, the computed tomographic scans showed a significant reduction in all of the previously identified metastases in all patients...

Switzerland, particularly its western region, has the highest incidence of melanoma in Europe. Although the risk of melanoma increases with sun overexposure during childhood, sun-related knowledge and attitudes of Swiss children are scarcely documented. We report the first investigation of the knowledge of the danger of ultraviolet radiation, attitudes towards a suntan and parental influence of schoolchildren in western Switzerland. All fifth, eighth and eleventh graders (average ages of 9, 12 and 15, respectively) in the 18 primary (fifth grade, n=431) and secondary (eighth and eleventh grades, n=837) public schools of La Chaux-de-Fonds were surveyed during regular school classes...

The evidence that PITX1 (pituitary homeobox 1) is a significant tumor suppressor in human cancer remains largely circumstantial, but it clearly warrants further study as little is known about the tumor-inhibitory roles of PITX1 in cutaneous malignant melanoma. The aims of this study were to investigate PITX1 gene expression in patients with cutaneous malignant melanoma and to evaluate its potential relevance to clinicopathological characteristics and tumor cell proliferation. Clinicopathological findings of patients with cutaneous malignant melanoma were analyzed retrospectively...

Nivolumab (Opdivo(®) ), pembrolizumab (Keytruda(®) ), atezolizumab, and pidilizumabab are anti-PD1 monoclonal antibodies. Nivolumab is licensed in advanced melanoma and second-line therapy of advanced or metastatic non-small cell lung cancer. When activated, the programmed cell death (PD)-1 is implicated in the inhibition of the immune system. Anti-PD1 removes this inhibition and allows the immune system to control tumour cell progression.(1-4) Immune-mediated toxicity of this treatment have been reported, either organ-specific toxicities - i...

An infrared (IR) absorbance sensor has been designed, realized and tested with the aim of detecting malignant melanomas in human skin biopsies. The sensor has been designed to obtain fast measurements (80 s) of a biopsy using a small light spot (0.5 mm in diameter, typically five to 10 times smaller than the biopsy size) to investigate different biopsy areas. The sensor has been equipped with a monochromator to record the whole IR spectrum in the 3330-3570 nm wavelength range (where methylene and methyl stretching vibrations occur) for a qualitative spectral investigation...

IKKα plays a mandatory role in keratinocyte differentiation and exerts an important task in non-melanoma skin cancer development. However, it is not fully understood how IKKα exerts these functions. To analyze in detail the role of IKKα in epidermal stratification and differentiation, we have generated tridimensional (3D) cultures of human HaCaT keratinocytes and fibroblasts in fibrin gels, obtaining human skin equivalents that comprise an epidermal and a dermal compartments that resembles both the structure and differentiation of normal human skin...

Importance: Indoor tanning is prevalent among young adults and women and is associated with increased risk of melanoma. Evidence suggests that indoor tanners may be more inclined to adopt poor photoprotective practices that further increase their risk of skin cancer; however, gaps in the literature exist in young adults and by indoor tanning frequency. Objective: To examine the association between indoor tanning frequency and behaviors related to skin cancer prevention and to investigate whether these associations vary by age group or sex...

Non-melanoma skin cancers (NMSC) are a growing problem given that solar UVB radiation exposure is increasing most likely due to depletion of the atmospheric ozone layer and lack of adequate sun protection. Better preventive methods are urgently required to reduce UV-caused photodamage and NMSC incidence. Earlier, we have reported that silibinin treatment activates p53 and reduces photodamage and NMSC, both in vitro and in vivo; but whether silibinin exerts its protective effects primarily through p53 remain unknown...

PURPOSE: Melanoma, squamous cell carcinoma (SCC), and basal cell carcinoma (BCC) can be used as a unique model to identify molecular mechanisms to distinguish rarely metastatic (BCC), often metastatic (SCC) and most metastatic (melanoma) cancer. It is known that epithelial-mesenchymal transition and stemness transcription factors (TWIST1, SNAI2/SLUG, and BMI1) play an important role in metastasis and their dysregulation has been demonstrated in metastatic cancers. We hypothesized that this spectrum of cutaneous cancers (BCC, SCC, and melanoma) would be a unique cancer model system to elucidate steps toward cancer invasion and metastasis...

BACKGROUND: Several cellular functions relate to ion-channels activity. Physiologically relevant chains of events leading to angiogenesis, cell cycle and different forms of cell death, require transmembrane voltage control. We hypothesized that the unordered angiogenesis occurring in solid cancers and vascular malformations might associate, at least in part, to ion-transport alteration. METHODS: The expression level of several ion-channels was analyzed in human solid tumor biopsies...

BACKGROUND: Topical imiquimod is sometimes used for lentigo maligna (LM) in-situ melanoma instead of surgery, but frequency of cure is uncertain. Pathological complete regression (pCR) is a logical surrogate marker for cure after imiquimod, although residual LM and atypical melanocytic hyperplasia may not be reliably distinguished. A trial comparing imiquimod versus surgery might be justified by a high imiquimod pCR rate. OBJECTIVES: Primary: to estimate pCR rate for LM following imiquimod...

Skin cancer (melanoma- and non-melanoma skin cancer) is one of the most rapidly increasing cancers worldwide. This study analysed the current and future economic burden of skin cancer in Belgium and the cost-effectiveness of primary prevention of skin cancer. A retrospective bottom-up cost-of-illness study was performed, together with a Markov model in order to analyse the cost-effectiveness and the budget impact analysis of primary prevention of skin cancer in Belgium. Total prevalence of skin cancer in Belgium was estimated to triple in the next 20years...

Melanoma is a common type of skin cancer with a high propensity to metastasize. Tyrosine kinase inhibitors targeting the mitogen-activated protein kinase (MAPK) pathway and immune checkpoint blockade have recently revolutionized the management of unresectable and metastatic disease. However, acquired resistance and primary non-response to therapy require novel treatment strategies and combinations. The purpose of this review is to provide a brief and up-to-date overview on the clinical management and current trial landscape in melanoma...
