CA-125 is elevated in viable pregnancies destined to be miscarried: a prospective longitudinal study.
OBJECTIVE
To assess the predictive value of E2, hCG, CA-125, and morphometric parameters in early pregnancies with demonstrable fetal heartbeat, complicated by bleeding.


METHODS
Prospective longitudinal follow-up.


METHODS
The emergency service of the Department of Obstetrics and Gynecology, "Rebecca Sieff" Hospital, Safed, Israel.


METHODS
Twenty-five consecutive patients with vaginal bleeding during weeks 7 to 12 of pregnancy who had demonstrable fetal heartbeat. Ten women with normal pregnancies, serving as controls.


METHODS
The serum levels and the morphometric parameters were related to the outcome of pregnancy as revealed by future hospitalization, delivery, or telephone questioning.


RESULTS
In the five patients who eventually aborted, the values of CA-125 were > 125 U/mL, whereas none of the successful pregnancies had a value > 93 U/mL. The mean values were 133 +/- 4.85 versus 36.95 +/- 23.1 U/mL for miscarriages and successful pregnancies, respectively. In normal pregnancies the respective value was 32.3 +/- 4.3 U/mL. Although mean E2 levels were lower in the serum of women who eventually aborted, there was a significant overlap of values with the successful pregnancies. All the other parameters measured had no correlation to the outcome of these pregnancies.


CONCLUSIONS
CA-125 may serve as an accurate predictor of the outcome in early pregnancies with demonstrable fetal heartbeat, which are complicated by bleeding.
