目的:以单中心资料为研究对象,建立包含超声声像图特征的甲状腺乳头状癌(papillary carcinoma of the thyroid,PTC)患者中央区淋巴结转移(central lymph node metastasis,CLNM)预测模型,以辅助临床进行术前评估、针对患者选择个体化的...目的:以单中心资料为研究对象,建立包含超声声像图特征的甲状腺乳头状癌(papillary carcinoma of the thyroid,PTC)患者中央区淋巴结转移(central lymph node metastasis,CLNM)预测模型,以辅助临床进行术前评估、针对患者选择个体化的治疗方案。方法:研究共纳入912例经术后病理学检查证实的PTC患者,收集一般情况、实验室指标和超声声像图,将其随机分为训练组(n=727)和验证组(n=185)。在训练组中研究CLNM的相关因素,采用logistic回归分析法建立预测模型,绘制列线图预测CLNM的风险,在验证组中对其效能进行验证,并利用临床决策曲线对其临床应用进行评价。结果:本研究建立了包含性别、年龄、病灶总直径(total tumor diameter,TTD)、促甲状腺激素(thyroid stimulating hormone,TSH)、钙化、病灶与甲状腺包膜的关系和桥本甲状腺炎的预测模型,在验证组和训练组中得到的曲线下面积(area under curve,AUC)分别为0.746和0.826。与术前超声相比,预测模型提高了诊断的灵敏度,并且通过临床决策曲线体现了其临床收益。结论:利用logistic回归建立的列线图预测模型,在预测PTC患者CLNM中体现出了较好的效能,能够补充超声诊断的不足。展开更多
