ObjectiveTo explore the classification of ultrasound breast imaging reporting and data system (BI-RADS) classification combined with serum trefoil factor 1 (TFF1) and human growth differentiation factor 3 (GDF3) in the differential diagnosis of benign and malignant breast masses. MethodsThe prospective study collected 113 female patients with breast mass who got treatment in Tangshan People’s Hospital from September 2020 to September 2023. Ultrasound diagnostic equipment was applied for ultrasound BI-RADS classification, ELISA method was applied to detect serum TFF1 and GDF3 levels, Consistency Kappa test was used to compare the consistency of ultrasound BI-RADS classification, serum TFF1 and GDF3 alone and combined in the diagnosis of benign and malignant breast masses and pathological results, In addition, receiver operating characteristic (ROC) curve was used to analyze the diagnostic value of the above indicators in the diagnosis of benign and malignant breast masses. ResultsAmong the 113 patients with breast mass, the pathological diagnosis showed benign mass in 48 cases and malignant mass in 65 cases. The serum levels of TFF1 [(1.62±0.25) ng/mL vs (1.24±0.27) ng/mL] and GDF3 [(118.62±21.73) pg/mL vs (96.47±16.05) pg/mL] in malignant patients were obviously higher than those in benign patients (P<0.001). There were 70 cases of malignant breast mass and 43 cases of benign breast mass according ultrasound BI-RADS classification combined with serum TFF1 and serum GDF3. The diagnosis consistency with pathological results was very high and Kappa value was 0.835 (P<0.001). The sensitivity and specificity of ultrasound BI-RADS classification combined with serum TFF1 and serum GDF3 in differential diagnosis of benign and malignant breast masses were 96.92% (63/65), 85.42% (41/48), respectively, the negative predictive value was 95.35 (41/43), and positive predictive value was 90.00% (63/70). The sensitivity, negative predictive value and accuracy were higher than those of ultrasonic BI-RADS classification and serum GDF3 alone (P<0.05), and the missed diagnosis rate was lower than those of ultrasonic BI-RADS classification and serum GDF3 alone (P<0.05). ConclusionsThe serum levels of TFF1 and GDF3 increase in patients with malignant breast masses. The combination of ultrasound BI-RADS classification and serum TFF1 and GDF3 can improve the sensitivity and accuracy of the diagnosis of benign and malignant breast masses, and reduce the missed diagnosis rate.
目的 探讨酶联免疫吸附试验(ELISA)检测血清甲胎蛋白异质体(AFP-L3)含量对原发性肝癌（PLC）的诊断价值。 方法 选择2011年3月－11月门诊或住院的137例患者临床检测甲胎蛋白(AFP)为阳性的肝病患者血清，应用上海逸峰生物科技有限公司提供的ELISA法AFP-L3检测试剂盒检测AFP-L3浓度，137例中男98例，女39例，年龄28～77岁。其中PLC 92例，良性肝病45例，后者包括肝硬化37例、慢性肝炎8例。分析PLC组与良性肝病组AFP-L3浓度差异，运用受试者工作特征曲线(ROC)分析AFP-L3含量在PLC鉴别诊断中的价值。 结果 PLC组AFP-L3浓度[（109.04 ± 62.51）ng/mL]明显高于良性肝病组[（25.96 ± 49.43）ng/mL，两组差异有统计学意义（t=8.28 ，P＜0.001）。ROC分析结果显示，曲线下面积为0.819，以AFP-L3浓度37.89 ng/mL为临界值，分析92例PLC患者与45例良性肝病患者AFP-L3浓度异常的灵敏度为83.69%，特异度为88.88%，阳性预测值为93.90%（77/82），阴性预测值为72.72%（40/55），诊断准确度为85.40%。 结论 应用简便快速的ELISA法检测AFP-L3浓度在PLC与良性肝病鉴别诊断中具有较高的临床价值，便于临床推广。
