Gestational trophoblastic disease

Most women with gestational trophoblastic disease are of reproductive age. Because the disease is readily treatable with favourable prognosis, fertility becomes an important issue. Hydatidiform mole is a relatively benign disease, and most women do not require chemotherapy after uterine evacuation. A single uterine evacuation has no significant effect on future fertility, and pregnancy outcomes in subsequent pregnancies are comparable to that of the general population, despite a slight increased risk of developing molar pregnancy again. If women develop persistent trophoblastic disease, single or combined chemotherapy will be needed. Although ovarian dysfunction after chemotherapy is a theoretical risk, a term live birth rate of higher than 70% has been reported without increased risk of fetal abnormalities. Successful pregnancies have also been reported after choriocarcinoma. Only a few case reports have been published on fertility-sparing treatment in placental-site trophoblastic tumour, and the successful rate is about 67%. Women are advised to refrain from pregnancy for at least 6 months after a molar pregnancy, and at least 12 months after a gestational trophoblastic neoplasia. Most of the contraceptive methods do not have an adverse effect on the return of fertility. Finally, at least one-half of these women suffer from some form of psychological or sexual problems. Careful counselling and involvement of a multi-disciplinary team are mandated. (C) 2012 Elsevier Ltd. All rights reserved.
