Abstract

Background/aims: For hepatocellular carcinoma (HCC) within a single subsegment, the superiority of anatomical subsegmentectomy over non-anatomical partial resection is still controversial. In this study, we assessed the potential benefit of subsegmentectomy.

Methodology: We selected 44 patients with a single HCC lesion within one subsegment who had undergone anatomical subsegmentectomy or non-anatomical partial resection from among 173 patients who underwent hepatectomy in our hospital from August 2003 to May 2013. We compared the results following anatomical subsegmentectomy (Group A; n = 16) and non-anatomical partial resection (Group N; n = 28).

Results: One- and two-year survival rates were 92.5% and 89.3%, respectively; 1- and 2-year recurrence-free survival (RFS) rates were 88.9% and 69.1%, respectively. There was no significant difference in overall survival or RFS between the groups. However, among HBV-positive patients, RFS was significantly better for Group A than Group N (p = 0.008).

Conclusions: For HBV-positive HCC within a single subsegment, we recommend subsegmentectomy.

单中心回顾性分析:解剖亚节段切除术与非解剖部分切除治疗单个亚节段内肝癌的比较

背景/目的:对于单个亚段内的肝细胞癌(HCC)，解剖亚段切除术优于非解剖部分切除术仍存在争议。在这项研究中，我们评估了亚节段切除术的潜在益处。方法:我们从2003年8月至2013年5月在我院行肝切除术的173例患者中选择44例在一个亚段内的单个HCC病变行解剖性亚段切除术或非解剖性部分切除术的患者。我们比较解剖亚段切除术后的结果(A组;n = 16)和非解剖性部分切除(n组;N = 28)。结果:1年和2年生存率分别为92.5%和89.3%;1年和2年无复发生存率(RFS)分别为88.9%和69.1%。两组患者的总生存率和RFS无显著差异。然而，在hbv阳性患者中，A组的RFS明显优于N组(p = 0.008)。结论:对于单个亚节段内的hbv阳性HCC，我们推荐亚节段切除术。
