ABSTRACT
Objective To evaluate the role of serum CA125 level in diagnosing the epithelial ovarian tumor.Methods Serum CA125 level of seventy-two patients who were operated for epithelial ovarian tumor between Apr 2005 and Jun 2007 in PUMC hospital were recruited and analyzed retrospectively.Using microparticle enzyme immunoassay(MEIA) to determine the serum CA125 level,and evaluate the serum CA125 level in diagnosing epithelial ovarian cancer.Results The CA125 was higher than 35?/ml in 35/39 ovarian serous cystadenocarcinoma cases with 89.7% positive rate,CA125 was higher than 35?/ml in 9/12 ovarian borderline serous cystadenoma with 75% positive rate,and CA125 was higher than 35?/ml in 4/21 ovarian serous cystadenoma with 19% positive rate.Conclusion The serum CA125 level before operation can predict benign epithelial tumor or epithelial ovarian cancer.
