目的

评估肝动脉化疗栓塞（TACE）联合同步DSA-CT引导下射频消融（RFA）治疗大肝癌（肿瘤最大直径≥5 cm）的安全性和疗效。

方法

2010年1月～2012年3月21例原发性肝细胞癌患者接受同步联合治疗。术后定期进行影像学检查并复查甲胎蛋白，评估联合技术成功率、局部肿瘤治疗反应、无疾病复发时间、患者存活情况和技术相关并发症。

结果

技术成功率100%，无重要并发症发生。介入术后1个月复查，病灶完全缓解19例（19/21，90.48%）、部分缓解2例（2/21，9.52%）。肿瘤坏死以凝固性坏死为主。在局部灭活肿瘤方面，单结节型完全坏死率（17/17，100%）高于多结节性病灶(2/4,50.00%；P=0.034）。随访2～28个月，19例完全缓解者平均无疾病复发时间为（11.8±6.0）个月。21例患者6、12、18个月生存率均为100%。

结论

TACE联合同步DSA-CT引导下RFA治疗大肝癌安全、有效。局部肿瘤灭活方面，单结节型病灶优于多结节病灶。

Objective

To assess the safety and efficacy of single-session combined therapy with transcatheter arterial chemoembolization (TACE) and DSA-CT guided radiofrequency ablation (RFA) in hepatocellular carcinoma (HCC) larger than 5 cm.

Methods

A total of 21 patients were treated with TACE immediately followed by DSA-CT-guided RFA. Rate of technical success, local-regional tumor response, recurrence-free survival time, survival rate and complications were evaluated at follow-up images and AFP (α-fetoprotein).

Results

Technical success was achieved in all 25 visible HCC. No major complications was observed in any patient. Nineteen patients were complete response (CR) and 2 were partial response (PR) after the 1st months. Coagulation necrosis was the major appearance. CR occupied 90.48% (19/21). PR occupied 9.52% (2/21). Local-regional tumor response in solitary nodular lesions (17/17, 100%) was superior to multiple nodular lesions (2/4, 50.00%; P=0.034). During follow-up period, mean recurrence-free survival time was 11.8±6.0 months in 19 cases with CR. The estimated overall survival rate at 6, 12 months and 18 months was 100%.

Conclusions

Single-session combined therapy with TACE and DSA-CT guided RFA in large hepatocellular carcinoma was safe and effective, especially for solitary nodular lesions.
