Total body skin examination for skin cancer screening in patients with focused complaints

2012

Background. The value of total body skin examination (TBSE) for skin cancer screening is controversial. Objective: We sought to determine whether TBSE could be helpful in patients with focused skin symptoms who would not otherwise have undergone TBSE. Methods: In a prospective, multicenter, cross-sectional study consecutive adult patients were recruited during a period of 18 months. Physicians first inspected, problem areas and uncovered areas and then performed TBSE. Equivocal lesions detected in both steps were excised or biopsied. Primary outcomes were the absolute and relative risks of missing skin cancer and the number of patients needed to examine to detect melanoma or another maligna…

Robustness, Stability, and Fidelity of Explanations for a Deep Skin Cancer Classification Model

2022

Skin cancer is one of the most prevalent of all cancers. Because of its being widespread and externally observable, there is a potential that machine learning models integrated into artificial intelligence systems will allow self-screening and automatic analysis in the future. Especially, the recent success of various deep machine learning models shows promise that, in the future, patients could self-analyse their external signs of skin cancer by uploading pictures of these signs to an artificial intelligence system, which runs such a deep learning model and returns the classification results. However, both patients and dermatologists, who might use such a system to aid their work, need to …

Malignant Scalp Tumors: Retrospective Analysis of 1000 Patients.

2022

Abstract Background: Limited data on large cohort of patients with malignant tumors of the scalp are available in the literature. e aim of this study was to review a large cohort of patients with malignant scalp tumors to determine epidemilogy, tumor characteristics of this region and treatment. Materials and Method: A retrospective review of patients with malignant scalp tumors diagnosed histopathologically between 2005 and 2021 was performed. Demographic features and tumor characteristics were analyzed. Results: A total of 1080 patients (M: F 3,5:1) were treated and followed up for a mean period of 42 months (12-120 months). Age at diagnosis ranged from 12 to 98 years. Most malignant scal…

The Italian Euromelanoma Day: evaluation of results and implications for future prevention campaigns.

2012

Background Melanoma incidence/mortality is increasing worldwide. “Euromelanoma Day” is a pan-European campaign for skin cancer prevention. Results of the 2010 Euromelanoma Day in Italy are reported herein. Materials and methods A questionnaire was used to collect data on participants' characteristics and suspected skin cancers. Result A total of 1085 participants was screened (64.1% females, median age 44 years). Suspicion rate, detection rate, and positive predictive values for melanoma were 1.3, 0.28 and 21.4%, respectively. Poorly educated, ≥35 years old, pale-skinned males were at higher risk for skin cancer than highly educated, <35 years old, darker-skinned females, although the latte…

Differentiating Malignant from Benign Pigmented or Non-Pigmented Skin Tumours—A Pilot Study on 3D Hyperspectral Imaging of Complex Skin Surfaces and …

2022

Several optical imaging techniques have been developed to ease the burden of skin cancer disease on our health care system. Hyperspectral images can be used to identify biological tissues by their diffuse reflected spectra. In this second part of a three-phase pilot study, we used a novel hand-held SICSURFIS Spectral Imager with an adaptable field of view and target-wise selectable wavelength channels to provide detailed spectral and spatial data for lesions on complex surfaces. The hyperspectral images (33 wavelengths, 477–891 nm) provided photometric data through individually controlled illumination modules, enabling convolutional networks to utilise spectral, spatial, and skin-surface mo…

Italian Euromelanoma Day Screening Campaign (2005-2007) and the planning of melanoma screening strategies.

2011

Although no study has definitively shown that unfocused screening of skin cancer is effective, many campaigns have been organized with the aim of increasing awareness on melanoma risk factors. The objective of this study was to analyse the results of the Skin Cancer Screening Day in Italy during the period 2005-2007, to determine the priorities for melanoma control plans in a Mediterranean country. A total of 5002 patients were screened by dermatologists in 31 cities. Individuals who considered themselves to have many naevi and those with a family history of melanoma showed a higher number of common and atypical naevi. Ten melanomas, 20 basal cell carcinomas and two squamous cell carcinomas…

TGF-&beta;/VEGF-A Genetic Variants Interplay in Genetic Susceptibility to Non-Melanocytic Skin Cancer

2022

Differential genetically determined expression of transforming growth factor-&beta; (TGF-&beta; pathway and of vascular endothelial growth factor-A (VEGF-A) might modulate the molecular &ldquo;milieu&rdquo; involved in the etio-pathogenesis of non-melanoma skin cancer (NMSC). We have evaluated the frequency of some functionally relevant SNPs of TGF-&beta; and VEGF-A genes in 70 NMSC patients and 161 healthy controls, typed for TGF-&beta;1 rs1800471, TGF-&beta;2 rs900, TGF-&beta;R1 rs334348 and rs334349, TGF-&beta;R2 rs4522809 and VEGF-A rs3025039 SNPs. TGF-&beta;R2 rs1800629G allele and related genotypes were found to be associated with a possible protective role against NMSC, whereas VEGF-…

Skin surveillance attitudes and behaviors in relation to skin checks for early signs of skin cancer in a sample of secondary school students and teac…

2012

&lt;p&gt;&lt;strong&gt;Background&lt;/strong&gt;: Malignant melanoma (MM) can be readily treated in its earliest stages: survival rate, when detected early, is up to 95,0%. This justifies investigations on contributive factors and measures for precocious detection of skin tumors to improve early detection and to increase survival rates. The purpose of this survey was to collect information about knowledge, attitudes and behaviors on prevention in relation to skin checks for early signs of skin cancer on a sample of secondary school students and teachers.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods&lt;/strong&gt;: A sample of secondary school students and teachers from Palermo, was recruited usi…
