TOPICS
ABSTRACT
Introduction:
Synchrotron radiation enables precise imaging of biological structures at the subcellular level, providing insight into both elemental composition and chemical properties. Increasing evidence suggests that its application in otolaryngology – particularly in the diagnosis of laryngeal cancer – may offer valuable support to existing diagnostic methods and deserves further development and implementation in translational research.
Aim of the research:
To evaluate the potential of synchrotron X-ray radiation in otolaryngology based on a literature review and to present findings from a pilot study using X-ray absorption spectroscopy (XAS) in laryngeal cancer samples.
Material and methods:
A literature review was conducted following PRISMA guidelines using databases such as PubMed, Medline, and Google Scholar. Experimental studies were carried out at the SOLARIS National Synchrotron Radiation Centre on samples of laryngeal squamous cell carcinoma using XAS (TEY and TFY modes) and scanning transmission X-ray microscopy (STXM) for elemental mapping.
Results:
The review confirmed the effectiveness of synchrotron-based techniques (XAS, STXM, µXRF) in subcellular imaging. In the examined cancer samples, a predominance of Fe³⁺ was observed, indicating oxidative stress. STXM imaging revealed heterogeneous distribution of elements (C, N, O, Fe), reflecting the biochemical complexity of the tumour. Synchrotron techniques enable the assessment of iron redox alterations as potential cancer biomarkers. They support early diagnosis and expand our understanding of tumour pathophysiology.
Conclusions:
The presented findings highlight the need for further research to facilitate the clinical translation of these methods.
