Fluorescence spectral analysis and logistic regression modeling for diagnosing basal cell carcinoma on head and neck.

The optical fluorescence method is distinguished by key features such as non-invasiveness, high sensitivity, and resolution, which are superior to traditional diagnostic approaches. Unlike histopathological examinations and biochemical analyses, optical diagnostic methods obviate the need for tissue sampling, enabling the analysis of virtually unlimited material. The research aims to examine the effectiveness of emission spectra analysis in the diagnosis of basal cell carcinoma (BCC) of the scalp and neck.

Methods of spectral diagnostics in modern prevention of oncological diseases.

This paper contains structured information on photodynamic diagnostics. Photodynamic diagnostics is a young diagnostic modality used in the detection of pre-neoplastic and very early neoplastic lesions. A characteristic feature of the presented method is its completely non-invasive nature and thus the possibility of multiple repetitions at the same patient.

Spectral analysis of basal cell cancer in vivo.

One of the most important features of optical biopsy methods is its non-invasive nature, high sensitivity and resolution in comparison to traditional diagnostic methods. Optical diagnostic methods, contrary to histopathological tests and biochemical analysis, do not require the collection of tissue samples for analysis, and the amount of analyzed material is practically unlimited. The aim of this study was to evaluate the usefulness of spectral studies in the diagnostics of skin basal cell cancer using a protoptive device in clinical conditions.
