Follow-Up of Gestational Trophoblastic Disease: How Often and How Long

This has already been discussed in previous chapters that gestational trophoblastic disease (GTD) is a group of conditions showing abnormal proliferation of the trophoblast. At one end of the spectrum of the disease is partial or complete molar pregnancy that, on a majority of instances, behaves like a benign condition but has the potential to recur and metastasise like a malignant lesion. At the other extreme, there is the more aggressive malignant disease of choriocarcinoma. Follow-up strategies are therefore tailored according to the correct diagnosis and treatment given, if any.
