Choriocarcinoma

Choriocarcinoma is a highly malignant tumor secondary to hydatidiform mole, abortion, or term delivery. Its incidence is about 0.0001% to 0.36%. A few can occur after ectopic pregnancy, and most are women of childbearing age. The ovaries that occasionally occur in unmarried women are called primary choriocarcinoma. In the 1950s, the mortality rate was very high. In recent years, the application of chemical drugs has significantly improved the prognosis of choriocarcinoma.
