Partial splenic embolization (PSE) is a non-surgical procedure developed to treat hypersplenism. The purpose of this study is to evaluate therapeutic benefits of PSE with follow-up radiofrequency ablation (RFA) treatment in hepatocellular carcinoma (HCC) patients with thrombocytopenia.
Between September 1999 and January 2007, a total of 20 patients with HCC who had a few lesions, each 3 cm or less in diameter, and liver function of Child-Pugh class A or B were enrolled into our study. The patients were diagnosed with marked thrombocytopenia (<50 x 10(3)/mm(3)), or mild thrombocytopenia (<80 x 10(3)/mm(3)) with decreased prothrombin activity. They were treated once or twice with PSE. RFA was given as a follow-up treatment 2 weeks after final PSE. The primary endpoint was a platelet-count increase and improvement of prothrombin activity, and the secondary endpoint was the initiation of RFA.
PSE was performed successfully in 19 patients (95%). Two weeks after final PSE, platelet counts increased significantly (38 +/- 14 x 10(3)/mm(3) vs. 97 +/- 43 x 10(3)/mm(3); P < 0.0001), and prothrombin activity improved significantly (59.3 +/- 19.8% vs. 65.2 +/- 17.9%; P < 0.0001). No patients had major complications during the PSE procedure. The secondary endpoint was achieved in 18 of 19 patients (94.7%). The mean overall survival was 2257 days (95% confidence interval; range, 1659-2855 days). The Kaplan-Meier cumulative survival rate was estimated to be 61.9% at 5 years.
PSE is a safe and effective treatment for thrombocytopenia and has adjuvant therapeutic benefits for the therapy of HCC.
部分脾脏栓塞术(PSE)是一种非手术治疗方法,用于治疗脾功能亢进。本研究旨在评估 PSE 联合射频消融(RFA)治疗伴有血小板减少症的肝细胞癌(HCC)患者的治疗效果。
1999 年 9 月至 2007 年 1 月,共纳入 20 例 HCC 患者,这些患者有少数直径 3cm 或以下的病灶,肝功能为 Child-Pugh 分级 A 或 B。这些患者被诊断为明显血小板减少症(<50×103/mm3),或伴有凝血酶原活动度降低的轻度血小板减少症(<80×103/mm3)。这些患者接受了 1 次或 2 次 PSE 治疗。PSE 治疗结束后 2 周行 RFA 治疗。主要终点是血小板计数增加和凝血酶原活性改善,次要终点是 RFA 的启动。
19 例(95%)患者成功完成了 PSE。PSE 治疗结束后 2 周,血小板计数显著增加(38±14×103/mm3 比 97±43×103/mm3;P<0.0001),凝血酶原活性显著改善(59.3±19.8%比 65.2±17.9%;P<0.0001)。PSE 过程中无患者发生严重并发症。19 例患者中有 18 例(94.7%)达到了次要终点。总的中位生存时间为 2257 天(95%可信区间;范围,1659-2855 天)。Kaplan-Meier 累积生存率估计为 5 年时 61.9%。
PSE 是治疗血小板减少症的一种安全有效的方法,对 HCC 的治疗具有辅助治疗作用。
