Abstract

Background

The superiority of anatomical liver resection (AR) for localized hepatocellular carcinoma (HCC) over nonanatomical liver resection (NR) remains controversial. This study aimed to investigate the impact of AR in preventing local and early HCC recurrence.

Methods

A total of 280 patients who underwent initial liver resection for solitary HCC ≤5 cm in diameter were categorized into the AR and NR groups and compared using propensity score matching analysis.

Results

Between the matched pairs (n = 87 in each group), the incidence rates of local and early (recurrence within 2 years after surgery) recurrences in the AR group were significantly lower than those in the NR group (13.8% vs. 28.7%, p = .025; 20.7% vs. 35.6%, p = .028, respectively). The overall survival in the AR group was better than that in the NR group (median: 13.4 vs. 7.6 years, p = .003). NR was among independent risk factors for early recurrence (odds ratio: 1.98, 95% CI: 1.1–3.6, p = .023) and prognostic factors for local recurrence (hazard ratio: 2.44, 95% CI: 1.4–4.4, p = .003).

Conclusion

AR is superior in controlling local and early recurrence postoperatively for solitary HCC ≤5 cm in diameter compared with NR.

肝细胞癌解剖性肝脏切除术对预防术后早期局部复发的影响。

背景：解剖性肝切除术（AR）治疗局部肝细胞癌（HCC）优于非解剖性肝切除术（NR）仍存在争议。本研究旨在探讨AR对预防局部和早期HCC复发的影响：方法：将280例因单发HCC直径≤5厘米而接受初次肝切除术的患者分为AR组和NR组，并采用倾向评分匹配分析法进行比较：结果：在配对组（每组87人）中，AR组的局部复发率和早期复发率（术后2年内复发）明显低于NR组（分别为13.8% vs. 28.7%，p = .025；20.7% vs. 35.6%，p = .028）。AR组的总生存期优于NR组（中位数：13.4年对7.6年，P = .003）。NR是早期复发的独立危险因素（几率比：1.98，95% CI：1.1-3.6，p = .023）和局部复发的预后因素（危险比：2.44，95% CI：1.4-4.4，p = .003）：结论：与NR相比，AR在控制直径≤5厘米的单发HCC术后局部和早期复发方面更具优势。
