摘　　要：目的 探讨钼靶X线诊断乳腺癌(breast cancer, BC)的影像学特征及诊断效能。方法 前瞻性选取舞钢市人民医院2018年2月—2019年10月收治的75例疑似BC患者作为研究对象,均行钼靶X线检查,并经手术病理检查,以病理检查结果为“金标准”,评估钼靶X线检查BC的灵敏度、准确度、特异度、阳性预测值(PPV)、阴性预测值(NPV),并观察钼靶X线检查下BC影像学特征。结果 75例疑似BC患者经病理检查,确诊56例,占74.67%;以病理诊断结果为金标准,经钼靶X线诊断BC的灵敏度为96.43%(54/56),准确度为93.33%(70/75),特异度为84.21%(16/19),PPV为94.74%(54/57),NPV为88.89%(16/18);恶性患者钙化灶(91.07%)、漏斗征(85.71%)、皮肤增厚(94.64%)、大导管征(87.50%)、异常血管征(96.43%)、牛角征(89.29%)、淋巴管癌栓(96.43%)占比高于良性患者(15.79%、26.32%、12.35%、21.05%、10.53%、10.53%、5.26%),差异有统计学意义(P<0.05)。结论 钼靶X线诊断BC准确度、灵敏度较高,可清晰显示良恶性病变组织影像学征象,可为临床治疗提供有效指导。Objective To investigate the imaging features and diagnostic efficiency of molybdenum target X-ray in the diagnosis of breast cancer(BC). Methods Totally 75 patients with suspected BC admitted to Wugang People’s Hospital from February 2018 to October 2019 were prospectively selected as the research subjects, all patients were examined by molybdenum target X-ray and the pathological examination was performed, the pathological examination results were regarded as the “gold standard”, the sensitivity, accuracy, specificity, positive predictive value(PPV) and negative predictive value(NPV) of molybdenum target X-ray in examination of BC were evaluated, the imaging features of BC under molybdenum target X-ray examination were observed. Results Among 75 suspected BC patients after pathological examination, 56 were diagnosed as BC, accounting for 74.67%;The pathological examination results were regarded as the gold standard, the sensitivity, accuracy, specificity, PPV and NPV of BC under molybdenum target X-ray examination were 96.43%(54/56), 93.33%(70/75), 84.21%(16/19), 94.74%(54/57) and 88.89%(16/18), respectively;The proportion of calcification focus(91.07%), funnel sign(85.71%), skin thickening(94.64%), large vessel sign(87.50%), abnormal vascular sign(96.43%), ox horn sign(89.29%), lymph-vessel cancer thrombus(96.43%) in malignant patients was higher than that in benign patients(15.79%, 26.32%, 12.35%, 21.05%, 10.53%, 10.53%, 5.26%), the difference was significant statistically(P<0.05). Conclusion Molybdenum target X-ray has good application value in the diagnosis of BC, it has high accuracy and sensitivity, can clearly display the imaging signs of benign and malignant lesions, and can provide effective guidance for clinical treatment.
