摘要
目的评价CA125对月经性气胸的诊断价值。方法分别对7例月经性气胸和10例非月经性的自发性气胸患者的血清CA125水平进行比较并描绘ROC曲线进行分析。结果月经性气胸患者的血清CA125水平为(75.99±44.85)U/ml,而非月经性的自发性气胸患者的CA125水平为(20.60±11.06)U/ml,两组比较差异有统计学意义(P<0.01)。以31.64U/ml为诊断临界值时,CA125诊断月经性气胸的灵敏度为100%,特异度为80%,ROC曲线下面积为0.943。结论血清CA125水平对月经性气胸有较好的辅助诊断价值,以31.64U/ml为诊断临界值较为合适。
Objective To evaluate the diagnostic value of serum CA125 in catamenial pneumothorax.Methods The serum concentrations of CA125 of seven patients with catamenial pneumothorax and ten patients with non-catamenial spontaneous pneumothorax were compared respectively,and were analyzed by using ROC curve.Results The serum concentrations of CA125 in the patients with catamenial pneumothorax were（75.99 ± 44.85） U/ml,while in the patients with non-catamenial spontaneous pneumothorax were（20.60 ± 11.06） U/ml.There was significant difference between the two groups（P0.01）.If 31.64 U/ml was used as cut off value,the sensitivity of serum CA125 in the diagnosis of catamenial pneumothorax was 100%,the specificity was 80%,and the area under curve（AUC） was 0.943.Conclusion Serum concentration of CA125 can be regard as a useful marker for the diagnosis of catamenial pneumothorax,and 31.64 U/ml can be used as the cut-off value.
