Summary

Basal cell carcinoma (BCC) is the most common form of cancer among the Caucasian population. Equivocal BCC lesions are usually diagnosed by means of a punch biopsy, but since the last few decades, non-invasive imaging techniques for the diagnosis of BCC gained popularity within the field of dermatology. Conventional optical coherence tomography (cOCT) is an example of a non-invasive imaging technique. Recent studies revealed that OCT assessors may achieve high diagnostic certainty and accuracy for diagnosing BCC. However, cOCT has a limited axial and lateral resolution and can therefore only visualize the gross architecture of the skin. It has been proposed that the diagnostic certainty and accuracy of cOCT could be optimized by improving the resolution. Line-field confocal optical coherence tomography (LC-OCT) is a new non-invasive imaging technique that provides tridimensional images of the skin with a cellular resolution. Although the resolution of LC-OCT is superior to cOCT, the penetration depth of LC-OCT (500µm) is limited compared to that of cOCT (1.0-1.5mm). In the proposed study, we aim to assess whether LC-OCT is superior to cOCT in terms of diagnostic accuracy for diagnosing BCC in equivocal BCC lesions.

DEVICE

cOCT and LC-OCT

cOCT: conventional optical coherence tomography (cOCT) is an established imaging modality within dermatology that enables visualization of the architecture of the skin with a penetration depth of 1.0 - 1.5mm. LC-OCT: Line-field confocal optical coherence tomography (LC-OCT) is a new emerging diagnostic modality within the field of dermatology. LC-OCT enables tridimensional imaging of the skin with a cellular resolution and BCC features on LC-OCT have been described. However, the penetration depth of LC-OCT (500µm), is limited compared to the penetration depth of cOCT (1.0-1.5mm)
