Outline of Final Research Achievements

Tumor grade and chemotherapeutic effect in rectal cancer, Gleason score in prostate cancer and histological subtype in uterine cancer can be predicted by amide proton transfer (APT) imaging, which is a representative of chemical exchange saturation transfer imaging. APT signal intensity (APTSI) obtained by this imaging reportedly reflects the amount of proteins and peptides. According to our results, APTSI is considered to suggest not only the difference in cell division but also the amount of intra- and extracellular mucin and soluble proteins in the glands for adenocarcinoma. APTSI could be a new biomarker for evaluating tumor aggressiveness.
