Increased levels of inhibin B, lactate dehydrogenase (LDH), human epididymis protein 4 (HE4), cancer antigen 19-9 (CA 19-9), carcinoembryonic antigen (CEA) and anti-Müllerian hormone (AMH) can be useful in the diagnosis of ovarian cancer as a pregnancy complication, since their levels are expected to be normal during gestation [23,29,31]. The gene discussed is WFDC2; the disease is ovarian carcinoma.
