“…Skin cancer is one of the most common cancers diagnosed in the United States [3]. A report has shown that the five-year survival rate of localized malignant melanoma is 99% when diagnosed and treated early, whereas the survival rate of advanced melanoma is only 25% [4]. Hence, it is particularly important to detect and classify dermatoscopic images so that skin cancer can be diagnosed early.…”

The early detection of skin cancer substantially improves the five-year survival rate of patients. It is often difficult to distinguish early malignant tumors from skin images, even by expert dermatologists. Therefore, several classification methods of dermatoscopic images have been proposed, but they have been found to be inadequate or defective for skin cancer detection, and often require a large amount of calculations. This study proposes an improved capsule network called FixCaps for dermoscopic image classification. FixCaps can obtain a larger receptive field than CapsNets by applying an efficient high-performance large-kernel at the bottom convolution layer whose kernel size is as large as 31 × 31, in contrast to commonly used 9 × 9. The convolutional block attention module was used to reduce the losses of spatial information caused by convolution and pooling. The group convolution was used to avoid model underfitting in the capsule layer. The network can improve the detection accuracy and reduce a great amount of calculations, compared with several existing methods. The experimental results showed that FixCaps is better than IRv2-SA in classification prediction of dermatoscopic images, which is achieved an accuracy of 96.49% on the HAM10000 dataset.

“…Although primary prevention through health education campaigns aiming at reducing sun exposure have not yet definitively reduced MM incidence (Karim-Kos et al, 2008), secondary prevention directed towards skin awareness, self-examination and full-body skin examinations by physicians can lead to a reduction in mortality and morbidity (Vandaele et al, 2000;Weinstock, 2006;Koh, 2007;Cainelli et al, 2008;Karim-Kos et al, 2008). However, no study has definitively shown that unfocused screening for skin cancer is costeffective and further evidence is needed to assess the effectiveness of an unfocused MM prevention programme.…”

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 were histopathologically confirmed. Our observations provide the following suggestions for melanoma prevention strategies: (a) an unfocused campaign is suitable to inform the public about the importance of self-examination of the skin, but is not useful to identify a larger number of melanomas; and (b) melanoma screening campaigns should focus on a selected population, which meets rigorous risk criteria to maintain higher cost-effectiveness. The financial support to effective melanoma screening programmes could be increased, especially in southern populations where lower levels of self-surveillance and socioeconomic conditions represent risk factors for late identification of melanoma.

“…To screen the whole population periodically in order to detect cutaneous melanoma, a moderate-frequency cancer, would then involve many dermatologists, with a questionable cost/benefit ratio. For these reasons, the screening of cutaneous melanoma in an asymptomatic population is not recommended by the main preventive and dermatologic associations [13,14,15,16,17,18]. What is recommended is instead to educate the population to detect pigmented lesions with total skin self-examination and to refer to a dermatologist when required [19].…”

Background: Cutaneous melanoma affects people at a relatively young age. The possibility of making a screening at the population level is strongly limited because of the high costs and the shortage of well-trained operators. Objective: To evaluate the possibility of a sustainable timetable of screening examinations for cutaneous melanoma. Methods: Subjects who contacted the Lega Italiana per la Lotta contro i Tumori (Italian League against Cancer) between January 2001 and December 2004 were followed up to December 2013 through linkage with the Trento Skin Cancer Registry. The cumulative incidence of cutaneous melanoma was calculated and compared with that observed in the general population. Results: Fifteen newly diagnosed cutaneous melanomas were observed in 3,635 subjects during the screening phase, while 14 new cases were diagnosed within December 2013, in the period of follow-up after the screening. The 95% confidence interval for the cumulative incidence of screened subjects included the cumulative incidence of the general population. No new cutaneous melanomas were detected in a 2-year period, after the first examination, 2 cases within 3 years. Conclusions: Based on our study, we think that in a selected population a screening programme can be performed every 2-3 years. This could help make a screening possible/sustainable for the early diagnosis of cutaneous melanoma in a public health context.
