Melanoma is traditionally considered to be a radioresistant tumor. However, radiotherapy and immunotherapy latest developments might upset this radiobiological dogma. Stereotactic radiotherapy allows high dose per fraction delivery, with high dose rate. More DNA lethal damages, less sublethal damages reparation, endothelial cell apoptosis, and finally clonogenic cell dysfunction are produced, resulting in improved local control. Radiotherapy can also enhance immune responses, inducing neoantigens formation, tumor antigen presentation, and cytokines release...

SDHD encodes subunit D of the succinate dehydrogenase complex, an integral membrane protein. Across cancer types, recurrent SDHD promoter mutations were reported to occur exclusively in melanomas, at a frequency of 4-5%. These mutations are predicted to disrupt consensus ETS-transcription factor binding sites and are correlated with both reduced SDHD gene expression and poor prognosis. However, the consequence of these mutations on SDHD expression in melanoma is still unclear. Here, we found that expression of SDHD in melanoma correlated with the expression of multiple ETS-transcription factors, particularly in SDHD promoter wild-type samples...

Although the vast majority of melanomas are characterized by a high metastatic potential, if detected early, melanoma can have a good prognostic outcome. However, once metastasised, the prognosis is bleak. We showed previously that uronyl-2-O sulfotransferase (Ust) and 2-O sulfation of chondroitin/dermatan sulfate (CS/DS) are involved in cell migration. To demonstrate an impact of 2-O sulfation in metastasis we knocked-down Ust in mouse melanoma cells. This significantly reduced the amount of Ust protein and enzyme activity...

Aldehyde dehydrogenase 1 (ALDH1) has been proposed as biomarker of stem cells for certain human cancers. ALDH1 expression has been correlated with poor patient outcomes in a variety of malignancies but better patient outcomes in others, and its prognostic significance in malignant melanoma is unclear. Thus, 68 melanoma patients with comprehensive clinical and pathologic follow-up data were used to construct a tissue microarray. A modified histological score (H-score) with a maximum score of 300 was used to quantify immunohistochemical staining for ALDH1...

The cancer-testis antigens (CTA) are a large family of tumor-associated antigens expressed by a variety of cancer cells and primitive germ cells of the adult testis and placenta. These tumor-restricted expressing patterns suggest that CTA would be ideal targets for tumor-specific immunotherapy. XAGE-1 is a CTA that was originally identified by computer-based screening, and four transcription variants, XAGE-1a, -1b, -1c and -1d, have been characterized to date. Although the presence of XAGE-1 transcripts has been reported in various cancers, the expression of XAGE-1b in melanoma has not been fully characterized...

Inherited genetic factors may modulate clinical outcome in melanoma. Some low to medium risk genes in melanoma susceptibility play a role in melanoma outcome. Our aim was to assess the role of the functional IRF4 SNP rs12203592 in melanoma prognosis in two independent sets (Barcelona N=493 and Essen N=438). Genotype association analyses showed that the IRF4 rs12203592 T allele increased the risk of dying from melanoma in both sets (Barcelona: Odds Ratio [OR]=6.53, 95%CI 1.38 to 30.87, Adj P=0.032; Essen: OR=1...

Nearly one-third of all melanoma patients will experience disease recurrence and the majority of the relapses eventually develop metastatic disease as a consequence of disease progression in the early-stage melanoma patients. Although the factors that predict the recurrence have already been described, very few numbers of studies have investigated the natural recurrence history of melanoma. In this retrospective study, we analyzed the time until recurrence along with the patterns and outcomes of the recurrences; thus, we aimed to understand the possible factors that might influence the recurrence course in early-stage cutaneous melanoma at the first relapse...

By the recent introduction of molecular targeting drugs against BRAF mutation and immune checkpoint inhibitors, the prognosis of patients with melanoma in advanced stage is now improving, but still in the minority. Mucosal melanoma lacks the BRAF mutations, and hence conventional chemotherapeutic regimens must be improved. We have conventionally used dacarbazine (DTIC) for patients with metastatic mucosal melanoma. However, the efficacy of DTIC in patients with metastatic mucosal melanoma has been limited. Therefore, we explored other possibilities to improve the prognosis of patients suffering from metastatic mucosal melanoma...

Metastatic melanoma has long been considered to have a very poor prognosis and to be chemo-resistant. However, a subgroup of patients with metastatic melanoma presents remarkable responses to chemotherapeutic agents, even in the absence of a response to modern targeted therapies and immunotherapies; accordingly, determining predictive biomarkers of the response to chemotherapies for metastatic melanoma remains a priority to guide treatment in these patients. We report a case study of a patient with B-Raf proto-oncogene serine/threonine kinase-mutated metastatic melanoma harbouring many genetic mutations...

BACKGROUND: The prognosis of cutaneous melanoma is correlated to histopathologic parameters such as Breslow thickness, the presence of mitosis, ulceration and lymphatic involvement at the moment of the diagnosis. On the other hand, the prognostic value of parameters such as age, sex, and tumor localization are still a matter of debate. We evaluated herein the prognostic factors in melanoma patients during a long term follow- up (60 months). METHODS: Melanoma patients presenting stage IB-III at diagnosis were included...

REVIEW
Benjamin Weide, Dario Neri, Giuliano Elia
Intralesional therapy of melanoma patients with locally advanced metastatic disease is attracting increasing interest, not least due to its ability to lead to both direct tumor cell killing and the stimulation of both a local and a systemic immune response. An obvious pre-requisite for this type of approach is the presence of accessible metastases that are amenable to direct injection with the therapeutic agent of interest. Patients who present with these characteristics belong to stages IIIB/C or IV of the disease...

Mucosal melanomas represent a rare entity with different risk factors and molecular features compared to cutaneous melanomas. They arise most commonly from mucosal surfaces in the head/neck region, the female genital tract (FGT) and the anorectal region. The aim of this study was to evaluate clinics, prognosis, and treatment options of patients with mucosal melanoma, in particular with regard to different primary sites.We retrospectively analyzed 75 patients with mucosal melanomas diagnosed in the years 1993 to 2015 in our department...

: Malignant melanoma of the vagina is a rare, aggressive malignancy of poor prognosis. It principally affects post-menopausal women, with a mean age of 57 years, and the factors that contribute to its appearance are not well known. The first case of primary malignant vaginal melanoma was reported in 1887 and modern literature has noted about 500 cases, globally. Vaginal melanomas constitute 0.3% of all malignant melanomas and fewer than 3% of all vaginal carcinomas. To date there is no clear consensus regarding treatment...

PURPOSE: Clinical trials showing programmed death (PD)-1-PD-ligand 1 (L1) axis as a promising therapeutic target in melanoma and non-small cell lung cancers have made the pathway a focus of recent attention. However, the data regarding PD-L1/PD-1 in breast cancer are inconsistent. Given the heterogeneity of breast cancers, the clinical relevance of PD-L1 and PD-1 tumor infiltrating lymphocytes (TIL) may vary according to subtypes of breast cancer. We aim to investigate PD-L1 expression in a large cohort of breast cancers and analyze its clinico-pathological as well as outcome relationship according to molecular subtypes...

BACKGROUND: Sentinel lymph node biopsy (SLNB) for head and neck melanoma is challenging due to unpredictable drainage. We sought to determine the frequency of drainage to multiple lymphatic basins and asked if this was associated with prognosis in a large, single-center cohort. METHODS: We queried patients diagnosed with head and neck melanomas who had a SLNB performed from January 1998 to April 2016. Demographic and clinical characteristics were compared using Student's t test, Pearson chi-square analysis, log-rank test, Wilcoxon-Mann-Whitney test, and Kaplan-Meier curves...

BACKGROUND: Melanoma is a highly metastatic type of cancer that is resistant to all standard anticancer therapies and thus has a poor prognosis. Therefore, metastatic melanoma represents a significant clinical problem and requires novel and effective targeted therapies. The protein kinase C (PKC) family comprises multiple isoforms of serine/threonine kinases that possess distinct roles in cancer development and progression. In this study, we determined whether inhibition of PKC could revert a major process required for melanoma progression and metastasis; i...
