Front Oncol 2022; 12:837057. [PMID: 35372037 PMCID: PMC8967159 DOI: 10.3389/fonc.2022.837057] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Accepted: 02/23/2022] [Indexed: 01/13/2023] Open
Abstract
The largest proportion of hereditary melanoma cases are due to pathogenic variants (PVs) in the CDKN2A/p16 gene, which account for 20%-40% of familial melanomas and confer up to a 30%-70% lifetime risk for melanoma in individuals with these variants. In addition, PVs in the CDKN2A gene also increase risk for pancreatic cancer (~5-24% lifetime risk). Individuals with PVs in the CDKN2A gene also tend to have an earlier onset of cancer. Despite these known risks, uptake of germline testing has been limited in the past, largely due to perceptions of limited benefit for patients. Prevention recommendations have been developed for individuals with CDKN2A PVs as well the providers who care for them. On the patient level, behavioral modifications regarding melanoma prevention such as wearing sunscreen, limiting prolonged sun exposure and practicing general sun safety can help reduce risks. Germline testing can provide motivation for some individuals to adhere to these lifestyle changes. On the provider level, pancreatic cancer surveillance for individuals with CDKN2A PVs has been increasingly endorsed by expert consensus, although the efficacy of these surveillance methods remains under study. This review summarizes the updated surveillance guidelines for individuals with CDKN2A PVs and explores the impact of genetic counseling and testing in influencing behavioral changes in these individuals.

Abstract
Malignant melanoma is considered the most lethal skin cancer if it is not detected and treated during its early stages. About 10% of melanoma patients report a family history of melanoma; however, individuals with features of true hereditary melanoma (ie, unilateral lineage, multigenerational, multiple primary lesions, and early onset of disease) are in fact quite rare. Although many new loci have been implicated in hereditary melanoma, CDKN2A mutations remain the most common. Familial melanoma in the presence of multiple atypical nevi should raise suspicion for a germline CDKN2A mutation. These patients have a high risk of developing multiple primary melanomas and internal organ malignancies, especially pancreatic cancer; therefore, a multidisciplinary approach is necessary in many cases. The value of dermoscopic examination and total body photography performed at regular intervals has been suggested by a number of studies, and should therefore be considered for these patients and their first-degree relatives. In addition, genetic counseling with the possibility of testing can be a valuable adjunct for familial melanoma patients. This must be performed with care, however, and only by qualified individuals trained in cancer risk analysis.

An interstitial deletion within 9p21.3 and extending beyond CDKN2A predisposes to melanoma, neural system tumours and possible haematological malignancies. J Med Genet 2016; 53:721-727.

Abstract
Familial atypical multiple mole melanoma syndrome (FAMMM) is characterised by dysplastic naevi, malignant melanoma and pancreatic cancer. Given that large deletions involving CDKN2A (cyclin-dependent kinase inhibitor 2A) account for only 2% of cases, we describe a family that highlights the co-occurrence of both melanoma and neural system tumours to aid clinical recognition and propose a management strategy. A patient with multiple neurofibromas was referred with a provisional diagnosis of neurofibromatosis type 1 (NF1). Prior molecular testing, though, had failed to identify an NF1 mutation by sequencing and multiplex ligation-dependent probe amplification. His family history was significant for multiple in situ/malignant melanomas at young ages and several different cancers reminiscent of an underlying syndrome. A search of the Familial Cancer Database, FaCD Online, highlighted several families with cutaneous melanoma and nervous system tumours who were subsequently identified to have large deletions spanning CDKN2A Although sequencing of CDKN2A and TP53 failed to identify a mutation, a heterozygous CDKN2A deletion was identified by targeted array comparative genomic hybridisation (CGH). Whole-genome oligonucleotide array CGH and SNP analysis identified an interstitial deletion of at least 1.5 Mb within 9p21.3 and spanning approximately 25 genes. Identification of the underlying molecular abnormality permits predictive testing for at-risk relatives. Given the young cancer diagnoses, a surveillance regimen was developed and a clinical team organised for ongoing management so that genetic testing could be offered to both adults and minor children. Surveillance recommendations addressed cancer risks associated with FAMMM, and other cancers exhibited by this family with a large contiguous gene deletion.

Abstract
Familial atypical multiple mole melanoma syndrome (FAMMMS) is an autosomal dominant genodermatosis characterized by multiple melanocytic nevi, usually more than 50, and a family history of melanoma. It is known to be associated with carcinoma of pancreas and other malignancies involving gastrointestinal tract, breast, lung, larynx, and skin in the kindred. There is no published report of FAMMMS in dark-skinned individuals. We report a case of FAMMMS in a dark-skinned adult Indian male, who had multiple extensive nevi all over the body and oral mucosa; associated with malignant melanoma, squamous cell carcinoma (Marjolin's ulcer), and carcinoma of pancreas. His father had died of carcinoma of lung and his sister had a partial phenotypic expression. The clinical presentation of the case is discussed with review of literature.

Abstract
Family members of melanoma patients are often called upon to provide support, ranging from monetary to medical assistance. Consanguineal relatives of melanoma patients are also at greater risk of developing the disease themselves. However, as a group, they have limited understanding of their melanoma risk and they demonstrate inadequate primary and secondary prevention behaviors. The optimal intervention strategies for improving the consistent use of such behaviors (i.e., improving rates of sun-protection behaviors and screening) remains unclear, necessitating further research.

Abstract
Atypical Mole Syndrome is the most important phenotypic risk factor for cutaneous melanoma, a malignancy that accounts for about 80% of deaths from skin cancer. Since early diagnosis of melanoma is of great prognostic relevance, the identification of Atypical Mole Syndrome carriers (sporadic and familial) is essential, as well as the recommendation of preventative measures that must be undertaken by these patients.We report two rare cases concerning patients with multiple primary skin melanomas in the setting of a familial and a sporadic syndrome of dysplastic nevi: the first patient is a 67-year-old patient with a history of multiple superficial spreading melanomas localized on his back. The second patient presented with multiple primary melanomas in advanced stage in the context of the so-called sporadic form of the syndrome of dysplastic nevi-AMS (atypical mole syndrome). In the first case, excision of the melanomas was carried out with an uneventful post-operative period. In the second case, disseminated metastases were detected, involving the right fibula, the abdominal cavity as well as multiple lesions in the brain. The patient declined BRAF mutation tests as well as chemotherapy or targeted therapies, and suffered a rapid deterioration in his general condition leading to death. We classified the second case as a sporadic form of the atypical mole syndrome, associated with one nodular and two superficial spreading melanomas.There are no data in the literature to allow us to understand if, in patients with multiple primary melanomas, there is any difference in terms of prognosis between those with and without a family history of a similar phenotype. To answer this and other questions related to these rare cases, further studies with a significant number of patients should be carried out.

Abstract
Melanocytic proliferations are notoriously difficult lesions to evaluate histologically, even among experts, as there is a lack of objective, highly reproducible criteria, which can be broadly applied to the wide range of melanocytic lesions encountered in daily practice. These difficult diagnoses are undeniably further compounded by the substantial medicolegal risks of an "erroneous" diagnosis. Molecular information and classification of melanocytic lesions is already vast and constantly expanding. The application of molecular techniques for the diagnosis of benignity or malignancy is, at times, confusing and limits its utility if not used properly. In addition, current and future therapies will necessitate molecular classification of melanoma into one of several distinct subtypes for appropriate patient-specific therapy. An understanding of what different molecular markers can and cannot predict is of the utmost importance. We discuss both mutational analysis and chromosomal gains/losses to help clarify this continually developing and confusing facet of pathology.

Abstract
Melanoma is a malignant neoplasm of the skin, originating from the melanocyte. Accounting for less than 5% of all skin cancers, melanoma is associated with approximately 75% of skin cancer-related mortality. Early detection of melanoma with surgical resection remains one of the critical factors determining favorable clinical outcomes for melanoma. This article discusses the epidemiology and diagnosis of melanoma, with specific attention to the role of the PET scan in the evaluation of early melanoma.

Abstract
OBJECTIVE Early detection of melanomas might increase survival chance. Patients can usually see primary lesions while inspecting their skin. Skin self-examination (SSE) is therefore the recommended pre-screening method. To maximize the likelihood that SSE will be performed, it is important to distinguish those factors that increase the chance of performance. The aim is to examine motivational differences between (a) melanoma-prone persons who perform SSE once every 2-3 months, and (b) melanoma-prone persons with a lower SSE frequency. METHODS A survey to assess socio-demographic factors, attitude, social influence, self-efficacy and intention to perform SSE. RESULTS Members (n=71) of 18 familial atypical multiple mole melanoma (FAMMM) families participated; 70% performed SSE at least once every 2-3 months. Adequate performers were more likely to have a partner, had a more positive attitude toward SSE, perceived SSE as less difficult to perform and had a stronger intention to perform SSE compared to poor performers. Logistic regression indicated attitude as the only reliable predictor of SSE performance. CONCLUSION We found that about one third of our genetically predisposed population did not report an adequate frequency of performing SSE. PRACTICE IMPLICATIONS Deficiencies in SSE practices in a genetically predisposed population are indicated.
