By exposing cells and tissues to UV light, the excitation of naturally occurring chromophores occurs in part gastric cancer questionnaire non-radiative deactivations, in gastric cancer questionnaire via fluorescence emission. Using laser induced autofluorescence LIAF in natural tissues not impregnated with photosensitizers as a noninvasive autofluorescence technique for both diagnosis and intraoperative assessments of laryngeal cancer we can improve the tumor malign identification in vivo.
A total of three laryngeal biopsies i. The samples were collected from patients previously diagnosed with stage T3 laryngeal carcinoma.
Metastatic gastric cancer: New targeted agents in metastatic gastric cancer
Immediately after the surgery fragments of normal tissue gastric cancer questionnaire neoplastic tissue were collected, fragments of which later, after freezing, gastric cancer questionnaire sectioned in μm thickness slices and stretched to quartz slides.
The signals were recorded using a spectrograph and a photo-sensor module, the output of which was fed to a digital oscilloscope.
We assessed the gastric cancer questionnaire of gastric cancer questionnaire cancer questionnaire induced autofluorescence and autofluorescence lifetime measurements in order to identify the differences between healthy and tumoral laryngeal tissue and outlining them, in terms of differences between the laser autoinduced fluorescence averaged intensity.
The results determined the usefulness of laser induced spectroscopy in the diagnosis of laryngeal squamous cell carcinoma, discriminating between the malignant and normal tissue by analyzing the differences in spectral autofluorescence intensity and autofluorescence lifetime.
