ABSTRACT: INTRODUCTION: In 2009, the American Joint Committee on Cancer (AJCC) incorporated the tumor mitotic rate in the melanoma pathological TNM staging system. To investigate the effect of this change on the pT1 substaging of primary cutaneous melanomas, we reclassified the cases collected by a cancer registry according to the 6th and the 7th editions of AJCC melanoma staging. METHODS: Patients with pathological T1 melanoma diagnosed in the period 2000-2008 were selected from Tuscan Cancer Registry. The histological reports were reviewed and pT1 melanomas classified according to both the 6th and the 7th editions of the AJCC staging system. The shift of melanomas between pT1 substages was analyzed. RESULTS: Among the 242 pT1 melanomas collected in the study period and with mitotic index available, there were 202 (83 % of all pT1) and 175 (72 %) pT1a, according to the 6th and the 7th editions of the AJCC melanoma staging, respectively. When the 7th edition was used, 20 % of all pT1a melanomas shifted to pT1b, and 32 % of all pT1b melanomas shifted to pT1a. A poor level agreement between the two TNM staging systems, measured by the Cohen's kappa coefficient, was found (K = 0.37). CONCLUSIONS: The addition of mitotic activity to the pathological staging resulted in an increase in pT1b proportion and in a change in the classification of some cases. This modification could influence the clinical approach, with a different use of the sentinel lymph node biopsy, and underlines the role of mitosis evaluation in the management of thin melanoma patients.

ABSTRACT: BACKGROUND: No studies are available in the literature on the distribution of different melanoma features and risk factors in the Italian geographical areas. OBJECTIVE: To identify the differences in clinical-pathological features of melanoma, the distribution of risk factors and sun exposure in various Italian macro-areas. METHODS: Multicentric-observational study involving 1,472 melanoma cases (713 north, 345 centre, 414 south) from 26 referral centres belonging to the Italian Multidisciplinary Group for Melanoma. RESULTS: Melanoma patients in northern regions are younger, with thinner melanoma, multiple primaries, lower-intermediate phototype and higher counts of naevi with respect to southern patients; detection of a primary was mostly connected with a physician examination, while relatives were more involved in the south. Northern patients reported a more frequent use of sunbeds and occurrence of sunburns before melanoma despite sunscreen use and a lower sun exposure during the central hours of the day. CONCLUSIONS: The understanding of differences in risk factors distribution could represent the basis for tailored prevention programmes.

3 Article Dermoscopic features of cutaneous melanoma are associated with clinical characteristics of patients and tumours and with MC1R genotype. 2014

Fargnoli, M C / Sera, F / Suppa, M / Piccolo, D / Landi, M T / Chiarugi, A / Pellegrini, C / Seidenari, S / Peris, K. ·Department of Dermatology, University of L'Aquila, L'Aquila, Italy. ·J Eur Acad Dermatol Venereol · Pubmed #24588892.

ABSTRACT: BACKGROUND: Several algorithms are available for the dermoscopic diagnosis of pigmented skin lesions. The MC1R gene is a key determinant of pigmentation characteristics that are established host-related melanoma risk factors. OBJECTIVES: To investigate the association of dermoscopic features of sporadic cutaneous melanomas with clinical characteristics of patients and corresponding tumours and with genetic changes in the MC1R and BRAF genes. METHODS: A total of 64 dermoscopic images of 62 patients were scored by ABCD rule and modified pattern analysis. Detailed patients' and melanomas' characteristics were collected. Patients were screened for germline MC1R variants and related melanomas for somatic V600 BRAF mutations. RESULTS: A lower total dermoscopic score (TDS) was observed in melanomas of patients with red hair (P = 0.019), due to reduced dermoscopic structures (P < 0.0001). Thicker melanomas showed higher TDS values (P = 0.021) due to sharper borders (P < 0.0001) and higher number of colors (P = 0.004). An atypical pigment network was prevalent in superficial spreading melanomas (P = 0.010), in individuals with dark skin (P = 0.043) and hair color (P = 0.001). An atypical vascular pattern was more frequent in nodular (P < 0.0001) and thick (P < 0.0001) melanomas, in individuals with skin type I-II (P = 0.037), blond or red hair color (P = 0.032) and blue or green eyes (P = 0.014). Melanomas of MC1R R carriers showed lower TDS value (P = 0.037), reduced dermoscopic structures (P = 0.001) and lower prevalence of atypical pigment network (P = 0.001). No differences were identified between BRAF-mutated or wild-type melanomas. CONCLUSIONS: We suggest a phenotypic/MC1R profile for melanoma patients and their tumours. Melanomas of MC1R R carriers show a significant lower TDS value, with reduced dermoscopic structures, and a lower prevalence of an atypical pigment network. Non-carriers of MC1R R variants develop melanomas dermoscopically characterized by an atypical pigment network which is prevalent in superficial spreading melanomas, in patients with dark complexion and less frequent in red-haired individuals.

4 Article Familial and sporadic melanoma: different clinical and histopathological features in the Italian population - a multicentre epidemiological study - by GIPMe (Italian Multidisciplinary Group on Melanoma). 2012

ABSTRACT: BACKGROUND: Having a familial member affected by cutaneous melanoma is a risk factor for this neoplasm. Only a few epidemiological case-control studies have been carried out to investigate whether familial and sporadic melanomas show different clinical and histopathological features. OBJECTIVE: The aim of this study was to evaluate eventual different features and risk factors in subjects affected by familial and sporadic cutaneous melanoma. METHODS: A case-control multicentre study interesting 1407 familial (n = 92) and sporadic (n = 1315) melanomas in the Italian population. The analysis was made using t-test for continuous variables and chi-squared test for categorized ones. The variables which have shown statistically significant differences in the two groups in the univariate analysis were included in a multivariate model. RESULTS: The results showed some main significantly clinical differences between the two groups investigated: earlier age at diagnosis, a greater proportion of sunburns and a higher number of naevi were observed for the familial cases compared with sporadic ones. Nevertheless, we did not find a diagnostic anticipation in familial melanomas, in fact the invasion level and the thickness of melanomas was similar in the two groups. CONCLUSION: Some relevant clinical differences are observed between the two groups examined. The familial melanoma members, although carriers of constitutional risk factors, are not careful enough to primary and secondary prevention.
