Background
- Cervical cancer is a significant global health issue, with over 600,000 new cases in 2020.
- In vivo fluorescence spectroscopy offers a noninvasive method to detect biochemical and morphological changes in dysplastic tissues.
Purpose Of The Study
- To evaluate the efficacy of an in vivo handheld probe using polarized fluorescence spectroscopy for cervical tissue analysis.
- To compare the diagnostic accuracy of polarized fluorescence spectroscopy with established methods like cytology, colposcopy, and histopathology.
Main Methods
- A cross-sectional observational study utilized a custom-built fluorescence spectroscope with a 405 nm laser diode.
- Cervical tissues were examined using a handheld probe based on polarized fluorescence spectroscopy principles.
- Tissues were classified based on co-polarized, cross-polarized, and co-minus cross-polarized light patterns.
Main Results
- In vivo polarized fluorescence spectroscopy proved to be an effective screening technique for cervical tissues.
- The use of co- and cross-polarized light significantly enhanced diagnostic accuracy.
- Co-minus cross-polarized light showed poor accuracy.
Conclusions
- Handheld polarized fluorescence spectroscopy is a fast, noninvasive, and quantitative diagnostic tool.
- With further development, this technology has the potential to become a standard cervical cancer screening method.
