[New technology of diagnosis of ovarian cancer].

It is difficult to identify early ovarian cancer at present. However, some tumor markers (CA125, CA19-9, CEA) and soon imaging system (MRI, CT, UT) and some oncogenes are available for diagnosis of ovarian cancer recently. Multivariate analysis of tumor markers has a possibility of stage I cancer. MRI is very useful to identify some cystic and hemorrhagic lesions. Amplifiers of N-myc and K-ras may be applied to diagnose ovarian cancer. In future, these new technologies may identify early ovarian cancer.
