The clinical value of serum CA125 in diagnosis of endometriosis caused pelvic pain

Objective To study the correlation of serum CA125 level and differentiation of endometriosis (EMs) and pelvic pain due to Ems.Methods The clincal data of 305 EMs patients were retrospectively analyzed,and they were divided into I,Ⅱ,Ⅲ,Ⅳ four stage according to r-AFS.The relevance of preoperative serum CA125 and differentiation of Ems and pelvic pain were assessed and statistically analyzed.Results The serum CA125 level was higher in Ⅲ,Ⅳ stage (69.4 ± 5.7) U/ml,(171 ± 11.5) U/ml than that in Ⅰ,Ⅱ stage (14.8 ± 1.2) U/ml,(36.3 ±3.0) U/ml,there was statistically significant difference (P ＜ 0.05).The positive rate of CA125 increased progressively (12.1％,21.5％,40.2％,63.9％),but the difference was not statistically significant(P ＞ 0.05).The pain syndromes in the clinical features of differentiation of Ems had obvious difference (P ＜ 0.05).Conclusion The serum CA125 detecting can be used in differentiation of Ems,and it has important value in diagnosis and prognosis of EMs. Key words: Cancer antigen 125 ;  Endometriosis
