Conclusion
In summary, annual screening with the use of
CA125/TVS can detect the precursors of type I
ovarian carcinoma, such as cystic tumors, and identify
patients who should be closely observed. Thus annual
screening may be useful for detecting type I ovarian
carcinoma at an earlier stage. Furthermore, annual
screening may improve the prognoses or induce the
down staging (from stage IV to stage III) of cases of
type II ovarian carcinoma, which would further
increase its efficacy in Asia, and also make it effective
in Europe and the USA, just as the UKCTOCS showed
a significant mortality reduction in the UK.
