The diagnostic value of CT in combination with serum CA125 and HE4 for ovarian cancer / 中国医师杂志

ABSTRACT

Objective To study the diagnostic value of CT combined CA125 and HE4 in differentiating the ovarian cancer from the benign.Methods A case-control study included 52 ovarian cancer patients,47 patients with benign ovarian tumors,and 40 healthy control subjects.Preoperative serum levels of HE4 and CA125 were measured and CT was performed.Results The serum levels of CA125 and HE4 in the ovarian cancer groups [(264.37 ± 138.46) KU/L,(280.38 ± 135.14)pmol/L] were significantly high-er than that in the benign ovarian neoplasm group [(52.51 ±5.29) KU/L,(40.52 ± 10.34) pmol/L] and healthy control group [(10.69 ±6.15)KU/L,(37.24 ±9.84) pmol/L] (P ＜0.01).The serum levels of CA125 showed statistically significant difference between the benign ovarian neoplasm groups and healthy control groups (P ＜ 0.05).The serum levels of HE4 did not show statistically significant difference between the benign ovarian neoplasm groups and healthy control groups (P ＞ 0.05).The diagnostic sensitivity (65.4％,80.8％,75.0％),specificity (74.5％,85.1％,76.6％),and accuracy (69.7％,82.8％,75.8％) of each CA125,HE4,CT method for ovarian cancer did not show statistically significant difference (P ＞0.05).The diagnostic sensitivity (92.3％),specificity (93.6％) and accuracy (94.8％) of combination of CA125 and HE4 and CT were significantly higher and showed statistically significant difference compared with one method (x2 =7.461 18.711,P ＜ 0.01),but no significant difference compared with any two methods (P ＞ 0.05).Conclusions The serum levels of HE4 and CA125 in the ovarian cancer group were significantly higher,and CT in combination with those two serum indices improved the diagnostic sensitivity,specificity,and accuracy of ovarian cancer.
