Measurement of CA125, carcinoembryonic antigen, and alpha-fetoprotein in ovarian cyst fluid: diagnostic adjunct to cytology.
This study used CA125, carcinoembryonic antigen ( CEA), and alpha-fetoprotein ( AFP) to classify ovarian cysts by measuring the levels of the three antigens; this information was useful when fluid obtained through laparoscopic puncture of ovarian cysts was submitted for cytologic examination from patients for whom tissue was unavailable for classification. We studied 136 consecutive cyst fluids (108 benign, 28 malignant) and correlated the findings with the tissue diagnosis. All three antigens were very low ( CEA, less than 0.5 ng/ml; CA125, 55-2,143 mu/ml; and AFP, less than 4.8 ng/ml) in follicular and lutein cysts. Markedly elevated CA125 (296-1,950,000 mu/ml) and low CEA (0.5-220 ng/ml) and AFP (less than 4.8 ng/ml) levels were seen in patients with serous neoplasms, both benign and malignant. Elevated CEA (greater than 600 ng/ml) and CA125 (56-65,330 mu/ml) levels were seen in primary mucinous cystadenoma and cystadenocarcinoma. Two patients with colonic carcinoma metastatic to the ovary had an elevated CEA (greater than 600 ng/ml) and a normal CA125. Only one patient, with a malignant teratoma, had an elevated AFP. The adjunctive use of CEA and CA125 is recommended for the classification of ovarian cysts.[1]References
