Ovarian tumours

Ovarian tumours are relatively common and account for ~6% of female malignancies. This article focuses on the general classification of ovarian tumours. For specific features, refer to subarticles.

Pathology

Subtypes
Primary ovarian tumours

Surface epithelial stromal ovarian tumours (60-70%)

* sometimes classified as a separate category rather than under epithelial 7

Germ cell ovarian tumours (~20%)

Sex cord / stromal ovarian tumours (8-10%)

Mixed

These are uncommon:

Other
Classification according to morphology
Predominantly cystic
Predominantly solid
Serological tests
  • CA-125 levels: elevated in most ovarian malignancies (~80% in general); some mucinous and germ cell tumours may not secrete this marker
  • AFP levels: elevated particularly with immature ovarian teratomas (~50% of cases) and ovarian yolk sac tumours
  • β HCG: in small number of dysgerminomas
  • human epididymis protein 4 (HE4)
Risk factors
General risk factors include
Protective factors
  • oral contraceptives
  • breastfeeding (this is controversial)
Risk assessment

Staging

The FIGO staging system is used for almost all of ovarian cancer: see ovarian cancer staging.
