In scirrhous gastric cancer, poorly differentiated carcinoma cells show diffuse infiltrative growth in stomach tissues, which makes endoscopic diagnosis of lesions very difficult. Therefore, novel diagnostic methods without depending on surface observations are required. Meanwhile, when circularly polarized light impinges to biological tissues, the polarization states of the scattered light are varied because of nuclear atypia of carcinoma cells in the scattering volume. This technique can be applied to the detection of scirrhous gastric cancer. In this paper, we report the experimental results for the stomach specimen extracted from the mouse mode of a scirrhous gastric cancer.
