摘    要:
目的:基于R软件介绍肿瘤风险预测模型的可视化-列线图的绘制和模型评价。方法:以SPSS软件自带案例乳腺癌生存数据为例,基于R软件包survival,rms拟合Cox回归模型并绘制生存概率风险列线图,用一致性指数(C-index)和校准曲线(calibration plots)评价模型区分度和一致性。结果:模型预测因素包括年龄、孕酮受体状态、淋巴结转移、病理学肿瘤大小。基于模型绘制的列线图评估个体化发病预后风险简单直观,模型一致性指数:0.70(0.62-0.80),校准曲线3年、5年、10年的预测生存概率与实际生存概率基本一致,反映该模型有较高的区分度(Discrimination)和一致性(Accuracy)。结论:基于Cox模型的列线图可通过多种预测因素量化肿瘤发病风险,应用简单直观、使用方便.可以为临床决策提供支持。

关 键 词:肿瘤风险预测  列线图  预测评价
