Autofluorescence of normal and tumor mucosa of human colon: a comprehensive analysis

Both 'in vivo' and 'ex vivo' spectrofluorometric studies of neoplastic and non-neoplastic mucosa of human colon have been carried out, in order to verify the potentials of tissue natural fluorescence as a possible parameter to distinguish normal from diseased tissues, Spectrofluorometric analysis performed at colonoscopy on patients affected by neoplasia, showed that adenocarcinoma, adenoma and non-neoplastic mucosa differ in the fluorescence emissions. The results have been interpreted according to the data obtained on cryostatic sections from biopsies by means of a microspectrofluorometric analysis carried out on each histological component.
