Background and Objectives: Raman spectroscopy (RS), which can detect molecular changes associated with cancer, was explored as a means of distinguishing normal and cancerous nasopharyngeal tissue. Study Design/Patients and Methods: Tissue from six patients with normal and cancerous biopsies was studied using a rapid acquisition Raman spectrometer. Results: Spectra were obtainable within 5 seconds. Consistent differences were noted between normal and cancer tissue in three bands 1,290-1,320 cm(-1)(P = 0.005), 1,420-1,470 cm(-1) (P=0.006), and 1,530-1,580 cm(-1) (P=0.002). Conclusions: Spectral differences appear to exist between normal and cancerous nasopharyngeal tissue. The ability to obtain spectra rapidly supports the potential for future in vivo application.
