目的

研究解剖性肝切除术对肿瘤直径≤2 cm合并微血管瘤栓(MVI)的肝细胞癌患者临床疗效及预后影响。

方法

回顾性分析2017年1月至2020年12月行手术治疗的肿瘤直径≤2 cm且合并MVI的肝细胞癌患者临床资料113例,分为解剖性肝切除组(AR组,n=46例)及非解剖性肝切除组(NAR组,n=67例)。临床数据分析采用SPSS 24.0统计学软件,围手术期指标等计量资料以(

xˉ
±s)表示,组间比较采用独立样本t检验;术后并发症等计数资料比较采用χ2检验。使用Kaplan-Meier法绘制患者总生存曲线及无瘤生存曲线,采用Log-Rank检验分析生存率差异。当P<0.05为差异有统计学意义。

结果

相较于NAR组,AR组手术时间更长、术中出血量更少(P<0.05)。两组患者术后并发症总发生率、1年及3年的累积总生存率比较差异无统计学意义(P>0.05)。AR组及NAR组1年及3年的累积无瘤生存率分别为84.8%、51.1%及72.4%、36.6%,两组间差异有统计学意义(χ2=4.105,P=0.043)。根据MVI分级将所有患者分为M1组及M2组。无论是M1或是M2分组中,AR亚组NAR亚组1年及3年的累积总生存率比较差异无统计学意义(P>0.05);但AR亚组NAR亚组1年及3年的累积无瘤生存率比较差异有统计学意义(P<0.05)。

结论

对于合并MVI的直径≤2 cm肝细胞癌患者,AR相较于NAR手术时间更长,但术中出血量更少。无论是M1或是M2患者,AR均可以使患者在术后无瘤生存率中受益。

Objective

To investigate the clinical efficacy and prognosis of anatomic hepatectomy for patients with hepatocellular carcinoma with tumor diameter ≤2 cm and microhemangioma invasion(MVI).

Methods

A retrospective analysis was performed on the clinical data of 113 patients with hepatocellular carcinoma with tumor diameter ≤2 cm and complicated with MVI who underwent surgical treatment from January 2017 to December 2020. They were divided into anatomic hepatectomy group(n=46 cases)and non-anatomic hepatectomy group(n=67 cases). SPSS 24.0 statistical software was used for clinical data analysis. Perioperative indicators and other measurement data were expressed as(

xˉ
±s). Independent t test was used for comparison between groups. Statistical data of postoperative complications were compared by χ2 test. Kaplan-Meier method was used to draw the overall survival curve and disease-free survival curve,and Log-Rank test was used to analyze the survival difference. When P<0.05,the difference was statistically significant.

Results

Compared with NAR group,AR group had longer operation time and less intraoperative blood loss,the differences were statistically significant(P<0.05). There were no significant differences in the overall incidence of postoperative complications,1-year and 3-year cumulative overall survival rate between the two groups(P>0.05). The 1-year and 3-year cumulative disease-free survival rates were 84.8% and 51.1% in the AR group and 72.4% and 36.6% in the NAR group,respectively,with statistically significant differences(χ2=4.105,P=0.043). All patients were divided into M1 group and M2 group according to MVI grading. There was no significant difference in 1-year and 3-year cumulative overall survival of AR subgroup and NAR subgroup in M1 or M2 subgroups(P>0.05). However,the 1-year and 3-year cumulative disease-free survival rates of AR subgroup and NAR subgroup were significantly different(P<0.05).

Conclusion

For the hepatocellular carcinoma patients with with diameter≤2 cm and microvascular invasion,AR has longer operative time and less intraoperative blood loss than NAR.In both M1 and M2 patients,AR can benefit patients in postoperative disease-free survival.
