血清4项指标联合检测在卵巢癌早期诊断中的临床价值

目的探讨联合检测血清人附睾蛋白4(HE4)、糖类抗原125(CA125)、糖类抗原199(CA199)和糖类抗原724(CA724)对卵巢癌早期诊断的临床价值。方法选择经病理证实卵巢癌患者40例(卵巢癌组)、卵巢良性肿瘤患者40例(卵巢良性肿瘤组)、体检健康者40例(健康对照组),采用电化学发光法检测血清CA125、CA199、CA724水平,用ELISA法检测HE4水平。分析单项检测与联合检测在卵巢癌诊断中的价值。结果卵巢癌组血清HE4、CA125、CA199、CA724各水平及阳性率明显高于卵巢良性肿瘤组和健康对照组,差异有统计学意义(P0.05)。卵巢良性肿瘤组和健康对照组比较,差异无统计学意义(P0.05)。卵巢癌组联合检测阳性率为92.5%,明显高于单项检测(P0.05)。HE4、CA125、CA199和CA724单项检测比较,HE4的灵敏度、特异度最佳。联合检测对卵巢癌Ⅰ期、Ⅱ期的检出率明显高于单项检测,差异有统计学意义(P0.05)。结论血清HE4、CA125、CA199和CA724联合检测可提高卵巢癌早期诊断的检出率。

Clinical value of combined detection of serum 4 indicators in early diagnosis of ovarian cancer

Objective To evaluate the clinical value of the combined detection of serum human epididymis protein 4(HE4) ,carbo‐hydrate antigen125(CA125) ,carbohydrate antigen199(CA199) and carbohydrate antigen724(CA724) in the early diagnosis of ovar‐ian cancer .Methods 40 cases of ovarian cancer verified by pathological examination (ovarian cancer group) ,40 cases of ovarian be‐nign tumor (ovarian benign tumor group) and 40 individuals undergoing the physical examination(healthy control group) were se‐lected .The levels of CA125 ,CA199 and CA724 were measured by the electrochemiluminescence method ,the HE4 level was meas‐ured by the enzyme‐linked immunosorbent assay(ELISA) .The values of single index detection and the combined detection in diag ‐nosing ovarian cancer were analyzed .Results Serum HE4 ,CA125 ,CA199 and CA724 levels and positive rates in the ovarian cancer group were significantly higher than those in the ovarian benign tumor group and the healthy control group (P< 0 .05) .There was no statistical difference between the ovarian benign tumor group and the healthy control group (P> 0 .05) .The positive rate of the combined detection was 92 .5% ,which was significantly higher than the single index detection (P < 0 .05) .In the comparison of HE4 ,CA125 ,CA199 and CA724 single detection ,the sensitivity and specificity of HE4 detection were best .The detection rates of the stage Ⅰ and Ⅱ of ovarian cancer in the combined detection were significantly higher than that in the single index detection (P<0 .05) .Conclusion The combined detection of serum HE4 ,CA125 ,CA199 and CA724 might increase the detection rate of early di‐agnosis of ovarian cancer .
