An interventional study of bimodal optical spectroscopy in Carcinomatous or Polymorphous Skin Lesions, sponsored by Centre Hospitalier Régional Metz-Thionville. Completed at 1 site in France. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-04-24.

Actinic keratosis are of utmost medical and economical interest because of their high prevalence (20 % of 60 year-old people and older in the Northern hemisphere) and their important cosmetic impact as such actinic keratosis mostly appear on photo-exposed skin sites. The surgeon in charge of such lesions' removal (i) some actinic keratosis adjoining carcinoma to be resected therefore causing the problem of functional areas damaging (eyelids, lips, etc.) or (ii) numerous actinic keratosis localized away from carcinoma (photo-carcinogenesis field) faces the issue of clinical evaluation of such lesions: which ones will spontaneously regress (it is supposed to be the case for 20 % of such lesions);which ones will remain and which ones will develop into invasive carcinomas ?
A non-invasive, non-traumatic, automated and real-time help for the clinical diagnosis orientation of such skin lesions could help improving diagnosis accuracy of the medical practitioner's visual inspection:
Centre Hospitalier Régional Metz-Thionville is the lead sponsor of 118 studies on the registry; 20 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
Device: bimodal optical spectroscopy
an optical fiber will be put in gentle contact with the patient's skin in order to acquire optical spectra
Optical spectroscopy's diagnostic validity for the 4 histological classes discrimination
Time frame: day 1
Statistical significance degree of the discrimination by molecular profiling (transcriptomic characterization) between in situ carcinoma (ISC) and invasive carcinoma (InvC).
Time frame: day 1
Statistical significance degree of the discrimination by molecular profiling (transcriptomic characterization) between 2 classes of actinic keratosis (AK) of clinical relevance: AK characterized by a "low" versus a "high" invasiveness risk
