摘要
目的构建超声误诊的卵巢囊肿性质的Fisher判别函数,提高诊断的敏感性和特异性。方法采用前瞻性研究方法,纳入132个超声误诊的卵巢囊肿,其中非赘生性囊肿53个,卵巢良性肿瘤47个,卵巢恶性肿瘤32个,以声像表现、血流信号、临床症状和妇科检查指标作为鉴别诊断变量,采用Fisher投影判别建立诊断模型。结果 3类卵巢囊肿的Fisher投影位置基本清晰;模型诊断非赘生性囊肿、良性肿瘤和恶性肿瘤的敏感性分别是78.9%、65.1%和71.9%(交叉性考核法)。结论 Fisher逐步判别分析为超声误诊的卵巢囊肿患者提供了较好的诊断模型,加强声像认识,详细询问病史,结合临床症状,采用模型判别等综合考虑是减少误诊的关键。
Objective The purpose of this study was to improve the sensibility and specificity to construct discrminant functions for the ultrasonography misdiagnosis ovarian cysts.Methods A prospective study was adopted and 132 cases ultrasonography misdiagnosis ovarian cysts were enrolled in this study（53 non-neoplastic ovarian cysts,47 benign ovarian tumors and 32 malignant ovarian tumors）.Differential diagnosis variable included ultrasonograph feature,Doppler blood flow signal,clinical symptoms,gynecological examination results,et al.Fisher’s diseriminant analysis was used to develop a diagnosis model.Results Fisher’s diseriminant analysis can clearly display the projective positions of three different kinds of ovarian cysts.The sensibility of discrimination model established for diagnosis non-neoplastic ovarian cysts,benign ovarian tumors and malignant were 78.9%,65.1% and 71.9%（Cross-validated）.Conclusion Stepwise discriminant analysis can provide a reliable model for differential diagnosis to the kinds of ovarian cysts.It is very important to combine with multi-parameter such as ultrasonography,medical history,clinical symptoms,discrimination model.
