| Outline of Final Research Achievements |
Using tissue imaging system with a near-infrared (NIR) spectrographic camera, normal tissue (non-cancerous part) and abnormal tissue (Cancer portion) was studied whether identifiable.Initially, we examined with 10 samples of early gastric cancer. The sensitivity and specificity were 60% and 80%, respectively. Then we examined with 18samples to assume that is increased. However, future increase of sensitivity and specificity were not observed.
As a major problem, the histopathology of cancer lesion often does not exhibit a uniform cell growth form.Macroscopic type and atypical degree of lesion would need to elucidate the differences. Then, we additionally examined by the cultured cells.
