Diagnosis and Treatment of Gestational Trophoblastic Disease (Gtd)

Gestational trophoblastic disease (Gtd) is actually a set of diseases that arise from cells related to pregnancy that become cancerous. Gtd occurs following fertilization when placenta forms in the absence of a fetus, or with a partial and abnormal fetus. Gtd can follow a normal full-term pregnancy, an ectopic pregnancy, a miscarriage, or an abortion.

Types of Gestational Trophoblastic Disease

There are two main types of Gtd: Hydatidiform mole and choriocarcinoma

Hydatidiform Mole
Hydatidiform mole is the most common form of Gtd, and occurs following fertilization when the placenta forms in the absence of a fetus, or with a partial and abnormal fetus. About 0.1% of all pregnancies result in hydatidiform mole, although the rate is higher in Asia and in women over 40 years old.

Choriocarcinoma
Choriocarcinoma is a cancerous condition that most commonly occurs following a hydatidiform mole. It is much more rare, occurring in about 0.004% of all pregnancies, although the rate is higher in Asia and in women over 40 years old.
