Melanoma-Nevus Discrimination Based on Image Statistics in Few Spectral Channels
2016
The purpose of this paper is to offer a method for discrimination of cutaneous melanoma from benign nevus, founded on analysis of skin lesion image. At the core of method is calculation of mean and standard deviation of pixel optical density values for a few narrow spectral bands. Calculated values are compared with discriminating thresholds derived from a set of images of benign nevi and melanomas with known diagnosis. Classification is done applying weighted majority rule to results of thresholding. Verification against the available multispectral images of 32 melanomas and 94 benign nevi has shown that the method using three spectral bands provided zero false negative and four false posi…
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…
