Trophoblastic tumour, oral contraceptive therapy and pregnancy associated alpha2-glycoprotein (PAAG), case report.

Pregnancy associated alpha2-glycoprotein (PAAG) and human chorionic gonadotrophin (HCG) levels were studied in a patient with an invasive mole who was being treated with cytotoxic drugs and oral contraceptives. Both the PAAG and HCG levels fell during cytotoxic drug treatment while oral contraceptives caused a rise in PAAG concentrations. A relation between oestrogen-induced PAAG and prolonged survival of trophoblastic tumour is proposed.
