| Outline of Final Research Achievements |
Clear cell carcinoma is the second most common ovarian cancer. Furthermore, clear cell carcinoma is resistant to anti-cancer agents and has high metastatic invasion ability, and thus has the worst prognosis among all ovarian cancers. From the above, there is an urgent need to develop useful markers for early detection of clear cell carcinoma. CA125 is elevated in normal ovarian cancer, but not in clear cell carcinoma. We have demonstrated the expression of HNF-1β in tissues and its mechanism of inducing resistance to anticancer drugs, but it is reported that Tissue factor pathway inhibitor 2 (TFPI2) is highly expressed only in clear cell carcinoma. It was The TFPI2 concentration and HE4 of ovarian cancer patients were measured, and it was confirmed that TFPI2 was specifically increased in clear cell carcinoma.
