CA_(125)是一种起源于胚胎体腔上皮的细胞表面抗原,血清CA_(125)检查能否作为子宫内膜异位症筛查项目目前尚有争议,因为其血清含量随月经周期而有波动,故CA_(125)测定对诊断轻度子宫内膜异位(?)敏感性低。本文作者对100名不孕症患者进行前瞻性研究。依据腹腔镜检查结果将病人分成正常、轻度(Ⅰ期)、中度(Ⅱ期)及重度(Ⅲ和Ⅳ期)子宫内膜异位症共4组。分别于月经周期的卵泡期、黄体期和月经期测定血清CA_(125),将所有测定结果进行统计分析。研究结果提示正常组的血清CA_(125)含量在月经周期的不同时期基本相同。而子宫内膜异位症各组的CA_(125)含量则存在差异:在ⅠⅡ期子宫内膜异位症病人中,月经期血清CA_(125)含
Whether CA_ (125) is a cell surface antigen derived from the epithelium of embryonic body cavity and whether serum CA 125 can be used as a screening test for endometriosis is still controversial because its serum content fluctuates with the menstrual cycle , So CA_ (125) determination of low sensitivity to diagnose mild endometriosis (?) Low. The author of 100 infertility patients prospective study. According to the results of laparoscopy, the patients were divided into four groups: normal, mild (stage Ⅰ), moderate (stage Ⅱ) and severe (stage Ⅲ and Ⅳ) endometriosis. Serum CA125 was measured in the follicular phase, luteal phase and menstrual cycle of the menstrual cycle respectively, and all the measurement results were statistically analyzed. The results suggest that the serum CA_ (125) content of normal group is basically the same in different periods of menstrual cycle. The endometriosis CA_ (125) content of each group there are differences: Ⅰ Ⅱ endometriosis patients, menstrual period serum CA 125
