Abstract
AbstractBackgroundExisting artificial intelligence for melanoma detection has relied on analysing images of lesions of clinical interest, which may lead to missed melanomas. Tools analysing the entire skin surface are lacking.ObjectivesTo determine if melanoma can be distinguished from other skin lesions using data from automated analysis of 3D‐images.MethodsSingle‐centre, retrospective, observational convenience sample of patients diagnosed with melanoma at a tertiary care cancer hospital. Eligible participants were those with a whole‐body 3D‐image captured within 90 days prior to the diagnostic skin biopsy. 3D‐images were obtained as standard of care using VECTRA WB360 Whole Body 3‐dimensional Imaging System (Canfield Scientific). Automated data from image processing (i.e. lesion size, colour, border) for all eligible participants were exported from VECTRA DermaGraphix research software for analysis. The main outcome was the area under the receiver operating characteristic curve (AUC).ResultsA total of 35 patients contributed 23,538 automatically identified skin lesions >2 mm in largest diameter (102–3021 lesions per participant). All were White patients and 23 (66%) were males. The median (range) age was 64 years (26–89). There were 49 lesions of melanoma and 22,489 lesions that were not melanoma. The AUC for the prediction model was 0.94 (95% CI: 0.92–0.96). Considering all lesions in a patient‐level analysis, 14 (28%) melanoma lesions had the highest predicted score or were in the 99th percentile among all lesions for an individual patient.ConclusionsIn this proof‐of‐concept pilot study, we demonstrated that automated analysis of whole‐body 3D‐images using simple image processing techniques can discriminate melanoma from other skin lesions with high accuracy. Further studies with larger, higher quality, and more representative 3D‐imaging datasets would be needed to improve and validate these results.
