Imaging Methods for the Diagnosis of Non-melanoma Skin Cancer and Its Precursors

Prospective, unicentric study that examines if imaging devices like total body photography, dermoscopy, optical coherence tomography and in vivo reflectance confocal microscopy as an addition to clinical examination lead to a benefit for patients in the diagnosis of non-melanoma skin cancer and their precursors

250 patients with lesions that are suspicious for non-melanoma skin cancer that had not yet had a biopsy, are randomized in 2 groups. The intervention group is examined with total body photography, dermoscopy, optical coherence tomography and in vivo reflectance confocal microscopy; the control group is examined with dermoscopy only. The aim of the study is to investigate whether these methods improve the early detection of non-melanoma skin cancer and their precursors. Examined are not only the differences in management of the lesions (excision, biopsy, local treatment or no treatment) and the diagnostic accuracy of the devices.
