50%-molar pregnancy
25% after abortion and ectopic
pregnancy and a few after normal
pregnancy
Non metastatic (locally invasive}lesions

Follows term pregnancy or miscarriage.
Only third of cases follow a molar gestation
Choriocarcinoma are commonly accompanied
by ovarian theca-lutein cysts.

*TREATMENT by hystrectomy is
preferred.
(locally invasive tumours are
ressistant to hystrectomy)
*For higher risk stage 1 and later
stages,adjuvant multidrug
chemotherapy is given.

Primary treatment is hysterectomy because
this tumor is relatively resistant to
chemotherapy.
Metastatic disease is common, and
combination chemotherapy is employed
