Spots Global Cancer Trial Database for Elucid Labs AIDA™ - Labelled Image Acquisition Protocol

Study Description

Brief Summary: Diagnosis of melanoma involves physical examination of the lesion with many dermatologists adjunctively employing dermoscopes. The rate of misdiagnosis of melanoma remains significant, along with a high rate of referral to biopsy. Elucid Labs (Waterloo, Ontario) has developed a novel handheld, digital dermoscope with accompanying visualization and analysis software - the Artificial Intelligence Dermatology Assistant (AIDA™). Apart from collecting conventional demoscopic images, AIDA also collects images at various spectral bands. The aim of this study is to understand and quantify the value of this novel adjunctive information for dermatologists diagnosing atypical skin lesions.

Detailed Description: Patients presenting with atypical skin lesions will undergo assessment by an investigator as per their standard clinical practice (not utilizing AIDA™). If a lesion meeting the inclusion-exclusion criteria is referred for biopsy, informed consent will be obtained and the subject will be enrolled. Subjects will then have images acquired by the AIDA™ system. All lesions scheduled for biopsy (Subgroup A) will be imaged along with at most 2 additional lesions meeting inclusion/exclusion criteria but not referred for biopsy (Subgroup B). For each lesion imaged using AIDA™, the investigator will manually segment the lesion image and list any lesion features which contributed to their recommendation to biopsy or not biopsy. The investigator will first score the lesion according to the ABCD rule using the standard dermoscopy image displayed. They will then state their diagnosis (malignant, dyplastic, or benign) and their diagnostic confidence using a visual analog scale. Once standard demoscopy diagnosis has been collected, the process will be repeated with the use of AIDA™ software outputs. Investigators will also provide an estimate of lesion depth based on AIDA™ depth images. All biopsy results will be recorded by the pathologist. Histopathology determination will be used as the definitive diagnosis of either positive (malignant/dysplastic) or negative (benign). Complete de-identified pathology reports may also be collected.
