Infrared spectroscopy of human tissue. IV. Detection of dysplastic and neoplastic changes of human cervical tissue via infrared microscopy

Abstract

Infrared absorption spectra of formalin-fixed, paraffin-embedded human cervical tissue are reported for normal, dysplastic and neoplastic samples. The spectral differences found in this study between these states of the tissues are far less than those observed for single cells by us and others. Nevertheless, we find a direct correspondence between spectral data from tissue sections, obtained from biopsies, and individual exfoliated cells, typically obtained during a pap procedure. We also find that spectra due to dysplastic samples fall about halfway between the spectral features of normal and cancerous samples.
