原图
该图展示了样本的评分变化和相关的临床信息变化。
对每个转移性胃癌患者(列)进行临床病理特征和分子特征注释。列注释表示上皮-间充质转化 (EMT)(间充质、非间充质);组织学(中度腺癌 (ADC)、ADC 差、印环细胞等);MSI 状态(MSS、MSI);EBV状态(阴性、阳性);分子亚型(染色体不稳定性(CIN)、EBV、基因组稳定(GS)、MSI-H);程序性死亡配体 1 综合阳性评分 (CPS)(高、低、NE);组织肿瘤突变负荷(tTMB);最佳总体反应 (BOR) (CR、PR、PD、SD);以及每个样本的二元 BOR(响应者、非响应者)。TMEscore、TMEscoreA 和 TMEscoreB 显示在面板顶部。高 TMEscore 能够识别 EBV 阳性和 MSI-H 患者以及免疫检查点阻断反应者。
