摘要:
目的评价MR磷谱分析( 31 P-MRS)早期监测肝细胞癌(HCC)化疗栓塞治疗疗效的价值。方法对15例因HCC接受化疗栓塞治疗的患者(共17个癌灶)分别在治疗前和治疗后48h内进行 31 P-MRS检查,5名健康志愿者也接受相同参数的检查以作为对照。比较肝癌组织和正常肝组织中的磷酸单酯(PME)和磷酸二酯(PDE)水平;分别计算化疗栓塞前后PME、PDE、与三磷酸核苷比值(PME/NPT)、PDE/NPT,并对治疗前、后数据进行统计学处理。与临床随访资料比较,考量各指标在早期评价疗效中的价值。结果HCC治疗后PME水平(中位数:1.38×10 7 ;范围:0.665×10 7 ~6.21×10 7 )低于治疗前(中位数:2.98×10 7 ;范围:0.846×10 7 ~102.5×10 7 )(P<0.05)。临床随访发现治疗有效病灶 31 P-MRS中,治疗后48h内与治疗前相比PME/NPT(P<0.01)和PME/PDE/NPT(P<0.01)比值均下降;临床随访中治疗无效的病灶,PME/NPT比值下降(P<0.05),而PDE/NPT比值轻度上升,但差异无统计学意义(P<0.05)。结论在肝细胞肝癌化疗栓塞治疗前和治疗后48h内,31 P-MRS中PME/NPT和PDE/NPT的比值变化对早期评价疗效和指导后续治疗有指导意义。
