Abstract
Gestational trophoblastic disease (GTD) consists of a spectrum of diseases, including hydatidiform moles, invasive mole, metastatic mole, choriocarcinoma, placental site trophoblastic tumour (PSTT) and epithelioid trophoblastic tumour (ETT). GTD is a relatively uncommon disease occurring in women of reproductive age, with high cure rates. Primary treatment of hydatidiform moles includes uterine evacuation, followed by close monitoring of serial hCG levels to detect for post-molar gestational trophoblastic neoplasia (GTN). In patients with GTN, the main therapy consists of chemotherapy, although some surgical procedures are important in selected patients to achieve curing. Hysterectomy is the mainstay treatment for PSTT or ETT and may be considered in selected patients for management of hydatidiform mole and malignant GTN especially in chemoresistant disease. Resection of metastatic lesions such as in the lung or brain can be considered in selected patients with isolated chemoresistant tumour. Surgical treatment of GTD will be discussed in this chapter.
