Gestational trophoblastic malignancy.

Gestational trophoblastic malignancy, although rare, offers the clinician the opportunity of being able to cure a malignant disease with cytotoxic chemotherapy. Such an opportunity is fulfilled only when the progress of the post-molar patients is monitored and chemotherapy instituted as soon as the malignant transformation of the mole is documented. The management and treatment of nine cases is presented and discussed.
