The development of immune checkpoint inhibitors (monoclonal antibodies targeting PD-1/PD-L1 or CTLA-4) represents a significant advance in the treatment of multiple cancers. Given their particular mechanism of action, which involves triggering CD4+/CD8+ T-cell activation and proliferation, they are associated with a specific safety profile. Their adverse events are primarily immune-related, and can affect practically all organs. In this context, dermatological toxicity is the most common, though it mostly remains mild to moderate and does not require discontinuation of treatment...

Background: AURKA kinase is an essential serine/threonine kinase for mitosis and chromosome stability. The aberrant amplification and overexpression of AURKA are commonly observed in various types of cancer, including cutaneous melanoma. However, the status and the clinical significance of AURKA copy number (CN) in acral melanoma (AM) have not been fully elucidated. Methods: Four hundred and seventy-two AM samples were included in the study. AURKA CN was examined using the QuantiGenePlex DNA Assay. We analysed the relationship of AURKA CN to clinicopathological characteristics and survival of patients with AM...

PURPOSE: BRAF inhibitors are clinically active in patients with advanced BRAFV600 -mutant melanoma, although acquired resistance remains common. Preclinical studies demonstrated that resistance could be overcome using concurrent treatment with the HSP90 inhibitor XL888. METHODS: Vemurafenib (960 mg PO BID) combined with escalating doses of XL888 (30, 45, 90 or 135 mg PO twice weekly) was investigated in 21 patients with advanced BRAFV600 -mutant melanoma. Primary endpoints were safety and determination of a maximum tolerated dose...

Brain metastases cause significant morbidity and mortality in patients with metastatic melanoma. Although adoptive cell therapy (ACT) with tumor-infiltrating lymphocytes (TIL) can achieve complete and durable remission of advanced cutaneous melanoma, the efficacy of this therapy for brain metastases is unclear. Records of patients with M1c melanoma treated with ACT using TIL, including patients with treated and untreated brain metastases, were analyzed. Treatment consisted of preparative chemotherapy, autologous TIL infusion, and high-dose interleukin-2...

Melanoma is the deadliest cutaneous neoplasm. To prevent metastasis, early diagnosis and surgical treatment is vital. Long non-coding RNAs (lncRNAs) may serve as biomarkers and therapeutic targets in tumors. We investigated the molecular mechanisms of lncRNA KCNQ1OT1 in melanoma. Real time PCR demonstrated that KCNQ1OT1 expression is up-regulated in melanoma tissues and cells. KCNQ1OT1 promoted cell proliferation and metastasis in melanoma. By directly bindin to miR-153, KCNQ1OT1 acted as a competing endogenous RNA (ceRNA) to de-repress MET expression...

LL-37 is a naturally occurring 37-amino acid that is part of innate immunity in human skin. Preclinical studies have demonstrated that intra-tumoral injections of LL-37 stimulate the innate immune system by activation of plasmacytoid dendritic cells, which mediate tumor destruction. LL-37 intra-tumoral injections have been utilized in a Phase 1 clinical trial for melanoma patients with cutaneous metastases. We report dermatologic toxicity in a 63-year-old woman with stage IIIC melanoma of the right calf and inguinal lymph nodes...

Immunotherapy prolongs survival in only a subset of melanoma patients, highlighting the need to better understand the driver tumor microenvironment. We conducted bioinformatic analyses of 703 transcriptomes to probe the immune landscape of primary cutaneous melanomas in a population-ascertained cohort. We identified and validated 6 immunologically distinct subgroups, with the largest having the lowest immune scores and the poorest survival. This poor-prognosis subgroup exhibited expression profiles consistent with β-catenin-mediated failure to recruit CD141+ DCs...

Cutaneous malignancy of the head and neck affects a large proportion of elderly patients. The severity ranges from small, easily treatable lesions to large, invasive, potentially metastatic tumors. Surgical treatment is the primary treatment of most skin cancers; however, geriatric patients are more likely to have multiple comorbidities that increase the risk of surgery. Multiple treatment modalities exist, including surgical, radiation, and medical therapy. Recommendations and treatment options for basal cell carcinoma, squamous cell carcinoma, Merkel cell carcinoma, and melanoma are outlined and reviewed...

BACKGROUND: Serum protein acidic and rich in cysteine (SPARC) is a matricellular glycoprotein, which regulates cell proliferation and facilitates intracellular transport of albumin bound particles including chemotherapeutic agents such as Nab-paclitaxel/ABI-007. Therefore the presence of SPARC may achieve higher intra-tumoral drug concentration with lower dosage and thus reduce systemic side-effects. Several trials of ABI-007, in melanoma, show promising clinical activity. DESIGN: Fifty-four cases of dermal based neoplasms were retrieved including 24 angiosarcomas (AS), 10 hemangiomas, 9 nodular melanomas, 4 Kaposi sarcomas (KS), 3 leiomyosarcomas (LMS), 3 atypical fibroxanthomas (AFX) and 1 spindle cell squamous cell carcinoma (SSCC)...

AIMS: Immune checkpoint inhibitors have become a successful treatment in metastatic melanoma. The high response rates in a subset of patients suggest that a sensitive companion diagnostic test is required. The predictive value of programmed death ligand 1 (PD-L1) staining in melanoma has been questioned due to inconsistent correlation with clinical outcome. Whether this is due to predictive irrelevance of PD-L1 expression or inaccurate assessment techniques remains unclear. The aim of this study was to develop a standardized digital protocol for the assessment of PD-L1 staining in melanoma and to compare the output data and reproducibility to conventional assessment by expert pathologists...

Background: It is unclear whether the established association between cutaneous melanoma (CM) and lymphoid neoplasms (LNs) differs across LN subtypes. This study quantifies risk for developing CM after specific LNs and, conversely, for developing specific LNs after CM, as well as assessing clinical impact. Methods: We identified a cohort of Caucasian adults (age 20-83 years) initially diagnosed with CM or LN, as reported to 17 US population-based cancer registries, 2000-2014...

Background: Statistically significant linkage of melanoma to chromosome 9q21 was previously reported in a Danish pedigree resource and independently confirmed in Utah high-risk pedigrees, indicating strong evidence that this region contains a melanoma predisposition gene. Methods: Whole-exome sequencing of pairs of related melanoma case subjects from two pedigrees with evidence of 9q21 linkage was performed to identify the responsible predisposition gene. Candidate variants were tested for association with melanoma in an independent set of 454 unrelated familial melanoma case subjects and 396 unrelated cancer-free control subjects from Utah, and 1534 melanoma case subjects and 1146 noncancer control subjects from Texas (MD Anderson) via a two-sided Fisher exact test...

Ultraviolet radiation (UVR) is a strong and ubiquitous risk factor for cutaneous melanoma, emitted naturally by the sun but also artificial sources. To shed light on the potential impact of interventions seeking to reduce exposure to UVR in both high and low risk populations, we quantified the number of cutaneous melanomas attributable to UVR worldwide. Population attributable fractions and numbers of new melanoma cases in adults due to ambient UVR were calculated by age and sex for 153 countries by comparing the current melanoma burden with historical data, i...

The incidence rates of cutaneous melanoma in non-Hispanic whites show an increasing tendency with age. While uveal melanoma in general is a rare disease, representing only 4% of all melanomas with an incidence rate of 0.6 per 100 000, it is still the most frequent malignancy of the eye. Synchronous occurrence of ocular and cutaneous melanoma is an exceptional rarity, due to the distinct genetic background of the diseases. We report the case of a 80-year-old man who underwent total excision of a cutaneous melanoma in 2008...
