Abstract
To study the diagnostic potential of fluorescence spectroscopy and its comparison with different screening methods, including Pap smear and colposcopy, in detecting early cervical neoplasia. The study was conducted on patients with gynecological complaints. A full gynecological workup of the patients was done along with Pap smear and colposcopy. Cervical biopsy was done in suspected cases and fresh tissue was sent to IIT for spectroscopy. There is a definite increase in NADH fluorescence (67.4%) and a decrease in collagen fluorescence (74%) in dysplastic tissues. When epithelial fluorescence and stromal fluorescence are considered together, diagnostic accuracy is increased to 96.5%. The clinical diagnosis of cervical neoplasia by spectroscopic methods is potentially a reliable, fast, and cost-effective alternative to the conventional smear test which needs trained personnel for its interpretation. Research is still continuing to obtain a statistically significant cutoff value from in vitro studies and then use them for in vivo study.
