Abstract:

摘要 目的 探讨DWI在局部进展期直肠癌(LARC)术前同步放化疗疗效预测中的作用。方法 将经内镜活检病理证实的LARC患者44例纳入分析。将患者术后病理分期与治疗前临床分期作比较,分为T-降期组和T-未降期组,比较放化疗前后以及组间ADC值、组间ADC变化量(ΔADC)以及变化率(ADC%)之间的差异,并根据ROC曲线得出疗效预测的最佳临界ADC值。结果 44例患者中7例(15.9%)获得pCR。患者同步放化疗前后ADC值差异有统计学意义(P=0.000)。同步放化疗前T-降期组ADC值明显低于T-未降期组,差异有统计学意义(P=0.007)。同步放化疗后T-降期组ADC值明显高于T-未降期组,差异有统计学意义(P=0.005)。T-降期组同步放化疗后ΔADC及ADC%均高于T-未降期组,差异有统计学意义(Z=-5.53, P=0.000; P=-5.09, P=0.000)。取治疗前ADC值0.87×10-3 mm2/s作为预测T分期是否降期的临界值,ROC曲线下面积为0.697(95%CI: 0.539~0.855),预测疗效的敏感度为87.5%,特异性为55.0%。结论 通过对ADC的定量分析可早期预测直肠癌患者对术前同步放化疗的敏感度,对术前同步放化疗疗效的判断也有一定的价值
