[Application of fourier transform infrared spectroscopy to non-invasive detection of pleomorphic adenoma of salivary gland in vivo].
In the present work, 20 patients with salivary pleomorphic adenoma were recruited for FTIR spectroscopic measurement. These obtained FTIR spectra were analyzed and compared. It was found that there were significant differences in the spectral features of the skin covering normal salivary gland, pleomorphic adenoma, and carcinoma change of pleomorphic adenoma, such as the changes in peak position, band shape and relative intensity of the bands in the ranges of 1000-1800 cm(-1) and 2800-3000 cm(-1). Pathological diagnosis demonstrated that 2 of the 20 patients suffered actually carcinoma change of pleomorphic adenoma, which is in good agreement with the result of FTIR spectroscopicmeasurement. FTIR spectroscopic m ethodsuggested that pleomorphic adenoma is the intermediate between normal salivary gland and carcinoma change of pleomorphic adenoma.
