| Abstract: | Background: Change in epithelial thickness is part of the neoplastic transformation process of the upper aerodigestive tract. The quantitation of native cellular fluorescence (NCF) may represent a noninvasive means of distinguishing such a change. Patients and methods: Nineteen patients with squamous neoplasms and 12 surgical specimens from cancer patients were analyzed for NCF using a hand-held fiber optic probe attached to a fluorescent spectrometer. Tumors and normal sites were analyzed for fluorescence, and tissue samples were obtained. Ratios of intensities of various emitted wavelengths were computed to quantitate and compare various spectral patterns. These ratios were then correlated with mucosal thickness. Results: The 330 nm peak in the excitation scan (λEx 200 to 360 nm, λEm 380 nm) was lost in the tumors compared with the normal sites. The 390 nm peak in the emission scan (λEx 340 nm, λEm 360 to 660 nm) was also lost. The 290 nm/330 nm ratio in the in-vivo excitation scan (λEx 200 to 360 nm, λEm 380 nm) correlated with changes in epithelial thickness. The 390/450 ratio in the emission scan (λEx 340 nm, λEm 360 to 660 nm) correlated negatively with the mean epithelial thickness. Conclusions: Native cellular fluorescence analysis can identify changes in neoplastic tissues, including changes in epithelial thickness. © 1995 Excerpta Medica, Inc. All rights reserved. |
