摘要: 目的 探讨应用米兰标准施行微波消融术(MWA)治疗肝细胞癌(HCC)患者影响生存的因素。方法 2013年1月~2016年12月我院消化内科住院的94例直径≤5 cm的HCC患者接受超声引导下MWA治疗,随访5年。分析不同HCC结节个数和不同肿瘤直径对总生存率(OS)和无进展生存率(PFS)的影响。结果 随访5年,本组HCC患者OS为64.9%,1 a和2 a 肿瘤复发率分别为12.8%和53.2%;HCC直径> 3 cm患者的PFS显著短于直径≤3 cm的患者(P=0.005),PFS≤2年的HCC患者OS显著低于PFS> 2年的患者(48.0%对 84.1%,P<0.001);多因素回归分析显示HCC直径> 3 cm (HR=0.42,95%CI:0.21~0.83,P=0.01)是MWA术后肿瘤复发的独立危险因素,而白细胞计数< 4.0×109 /L (HR=0.38, 95%CI:0.18~0.84,P=0.017)和PFS≤2 年(HR=0.24, 95%CI:0.10~0.56,P=0.001)是影响HCC患者OS的独立危险因素。结论 直径> 3 cm的HCC患者PFS较短,但似乎不影响OS,因为大多数肝内复发的HCC患者仍然可进行重复MWA治疗。

Abstract: Objective The aim of this study was to investigate the influencing factors of outcomes of patients with hepatocellular carcinoma (HCC) after ultrasound-guided percutaneous microwave ablation (MWA) by Milan criteria. Method 94 patients with HCC with hepatic solitary tumor≤5 cm were treated with ultrasound-guided MWA in our hospital between January 2013 and December 2016, and were all followed-up for 5 years. Independent risk factors for overall survival (OS) and progression-free survival (PFS) were analyzed. Result The cumulative overall survival rate in our series at 5 years were 64.9%, and the cumulative 1-year and 2-year tumor recurrence rates were 12.8% and 53.2%; the PFS in patients with tumor mass > 3 cm was significantly shorter than that in patients with tumor diameter≤3 cm (P = 0.005), and the OS in patients with PFS≤2 years was significantly shorter than that in patients with PFS> 2 years (48.0% vs. 84.1%, P < 0.001); multivariate Cox analysis showed that the tumor > 3 cm (HR=0.42,95%CI:0.21-0.83, P=0.011) was the independent risk factor for postoperative recurrence of HCC, and the leukocyte counts < 4.0×109 /L ( HR=0.38, 95%CI:0.18-0.84,P=0.017) and PFS≤2 years (HR=0.24,but most patients with intrahepatic tumor recurrence remain eligible for repeated treatment and get a relatively good outcomes. 95%CI:0.10-0.56,P=0.001) were the independent risk factors for OS. Conclusion The patients with hepatic tumor > 3 cm by Milan criteria might have less PFS after MWA.
