RESUMO
Background: The use of mobile electronic devices as support to medical activity was largely implemented in the past decade. Introduction: Our first aim was to evaluate the frequency of use of different electronic devices, that is, personal computer (PC), notebook, tablet, smartphone, in a pool of dermatologists recruited to perform multiple online testing session on difficult melanocytic skin lesions (MSLs) cases. The second aim was to evaluate the feasibility of each device in terms of teledermatologic diagnostic performance; the use of four different diagnostic methods, that is, intuitive diagnosis and three dermoscopic algorithms, was also investigated. Materials and Methods: A total of 111 dermatologists with 4 different levels of experience in dermoscopy, performed 4 tests (intuitive diagnosis and iDScore, ABCD rule, 7-point-checklist-based diagnosis) on 979 MSLs blinded cases. Each testing session was performed with a preferred device. Results: The overall highest areas under the receiver operating characteristic (AUROC) (82%) was obtained by young generation dermoscopists 1-4 years experience) when using an integrated clinical dermoscopic algorithm (iDScore) on a notebook. The average dermatologist using the iDScore obtained AUROC 77.40% with large screen devices (PC and notebook) 77.6% with small screen (tablet, smartphone) and 78.2% by combining the two. Discussion: Young generation of dermoscopists alternately use different devices, whereas elderly generation still prefer to use the PC. The diagnostic performances obtained with small/large screen were not statistically different from those obtained with fixed/mobile devices. Conclusions: Mobile devices were feasible tools to achieve adequate diagnostic accuracy in difficult MSLs, on a teledermatology setting, independently from participant skill level/age.

Line-field confocal optical coherence tomography (LC-OCT) is a new, noninvasive imaging technique for the diagnosis of skin cancers. A total of 243 benign (54%) and malignant (46%) skin lesions were consecutively enrolled from 27 August 2020, to 6 October 2021 at the Dermatology Department of the University Hospital of Siena, Italy. Dermoscopic- and LC-OCT-based diagnoses were given by an expert dermatologist and compared with the ground truth. Considering all types of malignant skin tumours (79 basal cell carcinomas (BCCs), 22 squamous cell carcinomas, and 10 melanomas), a statistically significant increase (p = 0.013) in specificity was observed from dermoscopy (0.73, CI 0.64-0.81) to LC-OCT (0.87, CI 0.79-0.93) while sensitivity was the same with the two imaging techniques (0.95 CI 0.89-0.98 for dermoscopy and 0.95 CI 0.90-0.99 for LC-OCT). The increase in specificity was mainly driven by the ability of LC-OCT to differentiate BCCs from other diagnoses. In conclusion, our real-life study showed that LC-OCT can play an important role in helping the noninvasive diagnosis of malignant skin neoplasms and especially of BCCs. LC-OCT could be positioned after the dermoscopic examination, to spare useless biopsy of benign lesions without decreasing sensitivity.
RESUMO
INTRODUCTION: Melanoma is the deadliest of all the skin cancers and its incidence is increasing every year in Europe. Patients with melanoma often present late to the specialist and treatment is delayed for many reasons (delay in patient consultation, misdiagnosis by general practitioners, and/or limited access to dermatologists). Beyond this, there are significant inequalities in skin cancer between population groups within the same country and between countries across Europe. The emergence of the COVID-19 pandemic only aggravated these health deficiencies. OBJECTIVES: The aim was to create an expert opinion about the challenges in skin cancer management in Europe during the post COVID-19 acute pandemic and to identify and discuss the implementation of new technologies (including e-health and artificial intelligence defined as "Smart Skin Cancer Care") to overcome them. METHODS: For this purpose, an ad-hoc questionnaire with items addressing topics of skin cancer care was developed, answered independently and discussed by a multidisciplinary European panel of experts comprising dermatologists, dermato-oncologists, patient advocacy representatives, digital health technology experts, and health technology assessment experts. RESULTS: After all panel of experts discussions, a multidisciplinary expert opinion was created. CONCLUSIONS: As a conclusion, the access to dermatologists is difficult and will be aggravated in the near future. This fact, together with important differences in Skin Cancer Care in Europe, suggest the need of a new approach to skin health, prevention and disease management paradigm (focused on integration of new technologies) to minimize the impact of skin cancer and to ensure optimal quality and equity.
