Outline of Final Research Achievements

Progranulin, Osteopontin, Midkine, GDF-15 develops the biomarker candidate gene which is specific for an uterus sarcoma from identification clinical specimen or cancer genome data.After identified as candidate biomarkers for diagnosing uterine sarcoma, we developed a novel measurement system for these factors using POCube, a fully automated immunological analyzer and developing a rapid and easy method.To investigate this mechanism, we developed a novel uterine orthotopic and metastatic model. Microarray analysis between orthotopic tumors with high and low metastatic potentials revealed differential expression of genes related to cell proliferation and migration (TNNT1, COL1A2, and ZIC1) .
To evaluate the diagnostic significance of 18F-FDG PET/CT textural features for uterine sarcoma, Entropy, as a single feature, yielded the greatest AUC of 0.974 and the optimal cut-off value of 2.85 for entropy provided 93% sensitivity, 90% specificity, and 92% accuracy.
