An in vitro diagnosis of oral premalignant lesion using time-resolved fluorescence spectroscopy under UV excitation-a pilot study
چکیده انگلیسی
In spite of rapid advancement in cancer treatment, early diagnosis of cancer and medicable precursors are still the finest approach towards the assurance of patient lives and enhancement in the quality of their life. In this regard, the present study deals with the time-resolved fluorescence spectroscopy of normal and premalignant oral tissues under UV excitations (280 nm and 310 nm). The decay kinetics at 350 nm emission of normal tissues exhibit higher fluorescence lifetime than that of premalignant tissues and subsequent statistical analysis shows that the data were statistically significant. Further, the decay kinetics at 450 nm emission for normal and premalignant oral tissues was obtained. Subsequently, statistical analysis revealed that except fast component, rest of the component lifetimes and fractional amplitudes were not statistically significant. An attempt has also been made to explore the better statistical tool to discriminate premalignant tissues from normal ones at 350 nm emission. Among stepwise linear discriminant analysis (SLDA) and receiver operator characteristics (ROC), the former discriminates premalignant from normal tissues with 86.7% specificity and 93.3% sensitivity. Hence, fluorescence lifetime spectroscopy at 350 nm emission opens a new avenue for early detection of oral cancer.
