TUMOR-MARKERS IN HYPERTENSIVE DISORDERS OF PREGNANCY

Plasma levels of tumor markers (CEA, TPA, CA 15.3, CA 125, alpha-fetoprotein) for 50 patients with hypertensive disorders of pregnancy were compared with those of 50 healthy women with singleton pregnancies and 50 healthy nonpregnant controls. With the exception of CEA all tumor marker values were higher in pregnant women, these differences being statistically significant (all p < 0.0001). Alpha-fetoprotein was lower in hypertensive than in healthy pregnant women (p = 0.0004), whereas CEA, CA 15.3 and CA 125 showed no statistically significant differences. TPA values in patients with hypertensive disorders of pregnancy (median 190 U/1) were 2.7 times higher than those of healthy pregnant controls (median 70.5 U/l) with a statistically significant difference (p < 0.0001). The individual degrees of disease severity demonstrated increasing TPA medians (pregnancy-induced hypertension: 106.5 U/l; pre-eclampsia: 200 U/l; HELLP syndrome: 339 U/1). TPA levels correlated positively with clinical severity of disease and negatively with fetal (r(S) = -0.58; p < 0.0001) and placental weight (r(S) = -0.44; p = 0.01).
