Internet-based skin cancer screening using clinical images alone or in conjunction with dermoscopic images: A randomized teledermoscopy trial
2017
Background Teledermoscopy involves the use of dermoscopic images for remote consultation and decision-making in skin cancer screening. Objective We sought to analyze the potential benefits gained from the addition of dermoscopic images to an internet-based skin cancer screening system. Methods A randomized clinical trial assessed the diagnostic performance and cost-effectiveness of clinical teleconsultations (CTC) and clinical with dermoscopic teleconsultations. Results A total of 454 patients were enrolled in the trial (n CTC = 226, n clinical with dermoscopic teleconsultation = 228). Teledermoscopy improved sensitivity and specificity (92.86% and 96.24%, respectively) compared with CTC (86.57% and 72.33%, respectively). Correct decisions were made in 94.30% of patients through clinical with dermoscopic teleconsultations and in 79.20% in CTC ( P P Limitations Potentially, a limitation is the establishment of an experienced dermatologist as the gold standard for the in-person evaluation. Conclusions The addition of dermoscopic images significantly improves the results of an internet-based skin cancer screening system, compared with screening systems based on clinical images alone.
