Abstract
In this study, Stokes shift spectroscopy (S3) is used for measuring the aggressiveness of malignant tumors. S3 is an optical tool which utilizes the difference between the emission wavelength (λem) and the absorption wavelength (λabs) (the Stokes shift) to give a fixed wavelength shift (Δλs).Our analysis of tumor samples using S3 shows grade 3 (high grade) cancers consistently have increased relative tryptophan content compared to grade 1 or 2 tumors. This technique may be a useful tool in the evaluation of a patient’s cancer.
