To investigate the technical success, safety and outcomes of transcatheter arterial chemoembolization (TACE) combined with simultaneous cone-beam computed tomography (CBCT)-guided microwave ablation (MWA) in small hepatocellular carcinoma (SHCC).
Retrospective analysis of 66 lesions in 50 patients (38 men, 12 women) who underwent TACE combined with simultaneous CBCT-guided MWA for SHCC. After 1 month of treatment, the tumor responses were assessed using the mRECIST criteria, along with interventional-related complications and changes in hepatic and renal function. Moreover, progression-free survival (PFS) and overall survival (OS) were calculated.
All patients achieved technical success. The mean target tumor size was 3.4 ± 0.7 (range, 2.2-4.9) cm. The mean energy, ablation duration per tumor, and the mean safety margin were 51.3 ± 8.4 kJ, 6.7 ± 0.8 minutes and 1.4 ± 0.6 cm, respectively. The 1-, 3-, and 5-year PFS rates were 90.0%, 65.4%, and 35.7%, respectively, with a mean PFS of 43.46 months; and the 1-, 3-, and 5-year OS rates were 98.0%, 89.8%, and 74.3%, respectively, with a mean OS of 54.90 months. Multivariate Cox regression analysis further illustrated that TACE combined with MWA in the treatment of a single tumor with a diameter of less than 3 cm was an independent protective factor for PFS and OS (p < 0.001). The patients had no major complications. Among the exceptions, one patient (2%) had an asymptomatic perihepatic effusion that resolved spontaneously, two patients (4%) developed massive right pleural effusion, requiring thoracic drainage, and another patient (2%) developed a hepatic subcapsular hemorrhage required interventional embolization.
CBCT-guided TACE combined with simultaneous MWA was a safe and successful treatment of SHCC with a high technical efficacy.
探讨经导管肝动脉化疗栓塞(TACE)联合同步锥形束 CT(CBCT)引导下微波消融(MWA)治疗小肝细胞癌(SHCC)的技术成功率、安全性和临床疗效。
回顾性分析 50 例(男 38 例,女 12 例)共 66 个病灶接受 TACE 联合同步 CBCT 引导下 MWA 治疗 SHCC 的患者资料。治疗后 1 个月,采用 mRECIST 标准评估肿瘤反应,同时记录介入相关并发症及肝肾功能变化。计算无进展生存期(PFS)和总生存期(OS)。
所有患者均达到技术成功。靶肿瘤平均直径为 3.4±0.7(2.2-4.9)cm。平均能量、每个肿瘤的消融时间和平均安全边缘分别为 51.3±8.4 kJ、6.7±0.8 分钟和 1.4±0.6 cm。1、3、5 年 PFS 率分别为 90.0%、65.4%和 35.7%,平均 PFS 为 43.46 个月;1、3、5 年 OS 率分别为 98.0%、89.8%和 74.3%,平均 OS 为 54.90 个月。多因素 Cox 回归分析进一步表明,TACE 联合 MWA 治疗单个肿瘤直径<3 cm 是 PFS 和 OS 的独立保护因素(p<0.001)。患者均未发生严重并发症。其中,1 例(2%)出现无症状性肝周积液,自行缓解;2 例(4%)发生大量右侧胸腔积液,需行胸腔引流;另 1 例(2%)发生肝包膜下血肿,行介入栓塞治疗。
CBCT 引导下 TACE 联合同步 MWA 治疗 SHCC 安全有效,技术成功率高。
