The objective of our study was to explore near\u2010infrared (NIR) Raman spectroscopy for distinguishing tumor from normal bronchial tissue. Bronchial tissue specimens (12 normal, 10 squamous cell carcinoma (SCC) and 6 adenocarcinoma) were obtained from 10 patients with known or suspected malignancies of the lung. A rapid\u2010acquisition dispersive\u2010type NIR Raman spectroscopy system was used for tissue Raman studies at 785 nm excitation.

Raman spectra differed significantly between normal and malignant tumor tissue, with tumors showing higher percentage signals for nucleic acid, tryptophan and phenylalanine and lower percentage signals for phospholipids, proline and valine, compared to normal tissue. Raman spectral shape differences between normal and tumor tissue were also observed particularly in the spectral ranges of 1,000\u20131,100, 1,200\u20131,400 and 1,500\u20131,700 cm\n                    <jats:sup>\u20131<\/jats:sup>\n                    , which contain signals related to protein and lipid conformations and nucleic acid's CH stretching modes.
