GESTATIONAL TROPHOBLASTIC DISEASE

Gestational trophoblastic disease (GTD) is actually a spectrum of neop lasms that include complete mole, partial mole, invasive hydatidiform mole, choriocarcinoma, and placental site trophoblastic humor. These n eoplasms account for less than one percent of all gynecologic neoplasm s, and all develop in association with pregnancy. Therefore, screening for them in the general population is not worthwhile. The oral contra ceptive is a chemopreventive for women at risk for GTD.
