摘要:
【摘要】 目的 探索经皮射频消融术(RFA)治疗兔椎体肿瘤模型不同消融时间的疗效及安全性。方法 采用CT引导经皮穿刺法将VX2瘤块接种入新西兰大白兔的腰椎内,成功建立20只兔椎体肿瘤模型。将其随机分为A、B两组,每组10只。测量肿瘤椎体的核素标准化摄取值(stand uptake value,SUV),然后对实验动物行消融治疗。A组消融持续时间3 min,B组为5 min,观察治疗后24 h动物急性瘫痪发生情况。治疗后第1天和第7天,实验动物再次接受PET CT检查,测定椎体肿瘤的SUV值,然后取肿瘤标本行病理检查。比较两组动物RFA术后的瘫痪率以及治疗前后不同时间点的肿瘤SUV值有无差异。结果 A、B两组动物射频后的瘫痪发生率差异有统计学意义(1/10 比 6/10、P < 0.05)。两组肿瘤模型消融前的SUV值分别为 4.60 ± 0.47、4.48 ± 0.45,治疗后第1天分别为0.94 ± 0.08、0.92 ± 0.07,治疗后第7天分别为0.93 ± 0.04、0.95 ± 0.06。两组椎体肿瘤的SUV值在治疗前、后差异有统计学意义(F = 3 257.87、P < 0.05),两组之间则差异无统计学意义。病理结果显示两组肿瘤模型的肿瘤细胞明显坏死,均未见明显残存肿瘤细胞。结论 应用RFA治疗兔椎体肿瘤,消融时间持续3 min已能有效杀伤椎体肿瘤细胞,且严重并发症的概率小。延长消融时间疗效无显著增加,但可能增加神经损伤的风险。
