摘要:
目的 探讨不同时间间隔肝动脉化疗栓塞术(TACE)联合射频消融(RFA)序贯治疗中晚期肝癌(HCC)的效果。 方法 回顾浙江大学丽水医院介入诊疗中心2012年2月—2017年12月99例HCC患者的临床资料,所有患者均接受了TACE和RFA序贯治疗。根据TACE和RFA的治疗间隔时间,将患者分为3组,分别为A组(0~5 d,30例)、B组(6~22 d,54例)和C组(>22 d,15例)。使用递归分割法选择最合适的TACE-RFA间期阈值,主要研究终点为总生存期(OS),次要研究终点为肿瘤无进展生存期(PFS)与治疗相关的不良事件。 结果 末次随访时间为2020年12月30日。分析结果显示较长的TACE-RFA时间间隔与较差的OS相关:A组vs. B组,P=0.694;A组vs. C组,P=0.037;B组vs. C组,P=0.023。C组15例患者中,73.3%(11/15)的患者死亡。3组中位OS分别为32.3、34.1和23.2个月。 结论 TACE和RFA序贯时间间隔与患者预后有关,较短的时间间隔可以提高中晚期HCC患者的OS和PFS,但最佳的时间间隔仍需进一步大样本多中心临床研究确认。 Abstract:Objective To investigate the appropriate interval between transcatheter arterial chemoembolization (TACE) and radiofrequency ablation (RFA) in treatment of advanced hepatocellular carcinoma (HCC). Methods The clinical data of 99 patients with HCC in Department of Radiology Lishui Hospital of Zhejiang University was retrospectively collected from February 2012 to December 2017. All patients received sequential treatment of TACE and RFA. The treatment interval of TACE and RFA was calculated, and the patients were divided into 3 subgroups: group A (0-5 days, n=30), group B (6-22 days, n=54), and Group C (>22 days, n=15). Recursive segmentation was used to select the most appropriate TACE-RFA interval threshold. The primary study endpoint was overall survival (OS), and the secondary study endpoint was tumor progression-free survival (PFS) and treatment-related adverse events. Results The last follow-up time was December 30, 2020. The data showed that longer TACE-RFA time intervals were associated with poor OS (group A vs. group B, P=0.694; group A vs. Group C, P=0.037; group B vs. group C, P=0.023). Among the 15 patients in group C, 73.3% (11/15) died. The median OS of the 3 subgroups were 32.3, 34.1, and 23.2 months, respectively. Conclusion The time interval between TACE and RFA is related to the prognosis of HCC patients. The shorter time intervals can improve OS and PFS in HCC patients. However, the optimal time interval still needs to be confirmed by large-scale multi-center clinical trials. -
