Previous studies have reported different risk factors for early and late intrahepatic recurrence after resection of hepatocellular carcinoma (HCC). However, the prognostic significance of the risk factors for early and late recurrence has not been clarified.
A total of 190 Hepatitis B surface antigen-positive patients who received curative resection for HCC were reviewed. We investigated prognostic factors for disease-free and overall survival after resection, and further analyzed the relationship between significant prognostic factors and risk factors for early (<or=14 months) and late (>14 months) intrahepatic recurrence.
The 5-year disease-free and overall survival rates were 43.9% and 71.5%, respectively. In multivariate analysis, adverse prognostic factors for disease-free survival were presence of serum HBeAg, perioperative transfusion, and the presence of portal vein invasion (PVI) and/or intrahepatic metastasis (IM). Multivariate analysis revealed that overall survival was associated with ICG R15, serum albumin, Edmondson-Steiner grade, and the presence of PVI and/or IM. Independent risk factors for early intrahepatic recurrence were perioperative transfusion and PVI and/or IM, whereas positivity for HBeAg was the only risk factor for late recurrence. In addition, post-recurrence survival in patients with late intrahepatic recurrence was completely comparable to that of patients who never experienced recurrence.
The presence of serum HBeAg, the risk factor for late intrahepatic recurrence did not affect overall survival after resection because late recurrence was relatively well controlled by current available treatments. To further improve long-term surgical outcomes, effective treatment and preventive methods for early intrahepatic recurrence should be investigated.
既往研究报道了肝细胞癌(HCC)切除术后早期和晚期肝内复发的不同危险因素。然而,早期和晚期复发危险因素的预后意义尚未明确。
回顾性分析190例接受HCC根治性切除的乙型肝炎表面抗原阳性患者。我们研究了切除术后无病生存和总生存的预后因素,并进一步分析了显著预后因素与早期(≤14个月)和晚期(>14个月)肝内复发危险因素之间的关系。
5年无病生存率和总生存率分别为43.9%和71.5%。多因素分析显示,无病生存的不良预后因素包括血清HBeAg阳性、围手术期输血以及门静脉侵犯(PVI)和/或肝内转移(IM)的存在。多因素分析表明,总生存与吲哚菁绿15分钟滞留率(ICG R15)、血清白蛋白、Edmondson-Steiner分级以及PVI和/或IM的存在有关。早期肝内复发的独立危险因素是围手术期输血以及PVI和/或IM,而HBeAg阳性是晚期复发的唯一危险因素。此外,晚期肝内复发患者复发后的生存与从未复发的患者完全相当。
血清HBeAg阳性作为晚期肝内复发的危险因素,并不影响切除术后的总生存,因为目前的现有治疗方法对晚期复发的控制相对较好。为进一步改善长期手术疗效,应研究早期肝内复发的有效治疗和预防方法。
