ABSTRACT
Objective To investigate whether there is a correlation between carbohydrate antigen125(CA125) and inflammation indicators in gynecological diseases ,analyze the possible mechanism of the disease .Methods Retrospectively analyze the regression and correlation between CA125 and routine blood classification indicators in 4 291 patients from department of reproductive health and gynaecology .Stepwise multiple regression model was used to analyze the common disease from department of gynaecology in‐cluding pelvic infection ,endometriosis ,uterine fibroids .Results The analysis of 4 291 cases showed that there was a correlation be‐tween CA125 and leukocyte count ,neutrophil‐to‐lymphocyte ratio (NLR) .The correlation coefficient was 0 .170 .For diseases of different types ,in patients with pelvic inflammation and endometrial ectopic there were correlations between CA125 and NLR .The correlation coefficient were 0 .290 and 0 .342 respectively .Conclusion There might be a correlation between CA125 and the inflam‐mation indicators .It should be carefully to diagnose cancer related diseases ,especially when inflammatory factors and CA125 in‐creased at the same time .
