Endodermal sinus tumour of the ovary: serum alpha-fetoprotein levels before and after treatment and during pregnancy. Case report.

We report the apparently successful treatment of an endodermal sinus tumour. The patient became pregnant after unilateral oophorectomy and adjuvant chemotherapy, and was delivered of a normal female infant. The levels of serum alpha-fetoprotein, having been raised before treatment of the tumour, were within the normal range during pregnancy and undectactable before and afterwards.
