ABSTRACT
Background: Cancer antigen 125 [CA-125] is a glyeoprotein biomarker that is used in women with pelvic masses such as endometriosis and maybe is useful in practice of patients suspicious to endometriosis
Objective: The aim of this study was to evaluate the association between preoperative serum CA-125 levels and clinic pathological characteristic in women with endometriosis, and find out the best serum CA-125 levels cut-off in pre and post menopause women
Materials and Methods: Serum CA-125 levels in 87 women aged 21-54 years suspected to endometriosis with pelvic pain, dysmenorrhea, or dyspareunia were measured preoperatively. Also the association between clinic pathological characteristic and serum CA-125 level were analyzed
Results: The mean age of women was 32.22+/-6.91. The mean serum CA-125 level was 49,93+/-4.30 U/rnL.
There was a significant correlation between the endometriosis stage, lesion size, adhesion score and preoperative CA-125 plasma concentration. However, we did not found significant differences in age, marital status, patient's complaints, and pelvic pain associated to Cal25 serum level
The suggested preoperative serum cut-off levels in premenopausal and postmenopausal patients were 37 U/ml and 35 U/ml, respectively
Conclusion: According to the results, preoperative serum CA-125 is an important predictor for patients with endometriosis and it should be taken into consideration when surgical management is suspected, especially if stage of disease, lesion size and adhesion score are undertaken
