Further Study of Spectrum from Stomach Cancer Serum Emission

Abstract

By using laser-induced Raman spectrum technology, we researched the spectrum characteristic of normal human, atrophic gastritis and stomach cancer. Three sharp peaks (A, B and C) can intensity of peak C excited by 488.Onm is higher than excited by 514.5nm in spectrum of stomach cancer whereas lower in other cases. We utilized it as a criterion and got an accuracy of 80.77% in stomach cancer detection. Results showed that it is available of detection of stomach cancer and pre-stomach cancer.
