SCI REP:不可逆电穿孔对结直肠癌肝转移鼠模型的长期疗效

2017-03-27 xingxiaowei MedSci原创

近年来,不可逆电穿孔被认为是肝部肿瘤消融疗法的替代选项之一。与其他传统消融疗法(如射频、微波消融)不同,不可逆电穿孔不会引起热损伤,不会影响临近重要结构,因而对于预防血管周围肿瘤复发有潜在应用价值。

近年来,不可逆电穿孔被认为是肝部肿瘤消融疗法的替代选项之一。与其他传统消融疗法(如射频、微波消融)不同,不可逆电穿孔不会引起热损伤,不会影响临近重要结构,因而对于预防血管周围肿瘤复发有潜在应用价值。

SCI REP近期报道了一篇文章,研究了不可逆电穿孔的长期肿瘤学结果。作者使用了46只肝脏KM12C肿瘤种植鼠模型,使用不同的电压(2000V/cm,1000V/cm)的电流进行实验,观察高剂量不可逆电穿孔对于实验动物长期生存的影响以及其在肿瘤组织中诱导的组织学改变。肿瘤持续生长直至实验动物达到终点。观察组织学特点并半定量分析肿瘤坏死程度。实验结果表明,与sham组相比2000V/cm的不可逆电穿孔治疗可以显着延长中位生存时间(112.5±15.2 vs 74.3±6.9)。1000V/cm组的中位生存时间与sham组无明显差异(83.2±16.5 vs 74.3±6.9)。组织学检查证明2000V/cm组的肿瘤凋亡率为63.05%±23.12,1000V/cm组为17.50%±2.50,sham组为25.6%±22.1(p=0.001)。

作者最后得出结论,2000V/cm的不可逆电穿孔治疗可以延长生存时间,并且会导致更高的肿瘤坏死率。
