单个3厘米的肝癌结节手术切除与射频消融治疗的长期结果:意大利多中心调查结果
背景和目的
这个研究的目的是比较肝切除术和射频消融术对单个3cm和代偿性肝硬化病人的肝细胞癌结节的治疗。
方法
这个研究在意大利15个研究中心观察了包含544名Child-Pugh
A级肝硬化病人(246名在肝切除组,298名在射频消融组)。总体生存率和肿瘤复发率是通过倾向评分前后的Kaplan
Meier法分析的。Cox回归模型被用来判定与总体生存率和肿瘤复发率相关的因素。
结果
肝切除组两例围手术期死亡率的观察:主要并发症的发生率在肝切除组是4.5%,而在射频消融组是2.%。肝切除组四年总体生存率是74.4%,射频消融组是66.2%
(p=0.353). 。肝切除组四年累积肝细胞癌复发率是56%,射频消融组是57.1%
(p=0.765) 。监测到消融组局部肿瘤进展率在20.5%,在切除组是1
(p<0.001)。通过倾向评分法,尽管在切除组病人中观察到了一种低复发的趋势,生存率和复发率仍然没有显著的区别。高龄和高甲胎蛋白水平对不利的总体生存是独立的预测因素,然而高龄和高丙氨酸氨基转移酶(ALT)水平结果证明是与高复发率相关的独立因素。
结论
尽管射频消融术有较高的局部肿瘤进展率,但在发生肝硬化的单个3cm的肝细胞癌结节,射频消融术能提供与肝切除相匹配的疗效。

Long-term effectiveness of resection
and radiofrequency ablation for
single hepatocellular carcinoma ?3cm.
Results of a multicenter Italian
survey
Background & Aims
Th
e aim of this study was
to compare liver resection and
radiofrequency ablation in patients
with single hepatocellular carcinoma
?3cm and compensated cirrhosis.
Methods
The study involved 544 Child-Pugh
A cirrhotic patients (246 in
the resection group and 298
in the radiofrequency group)
observed in 15 Italian centers.
Overall survival and tumor
recurrence rates were analyzed
using the Kaplan Meier method
before and after propensity
score matching. Cox regression
models were used to identify
factors associated with overall
survival and tumor recurrence.
Results
Two cases of perioperative mortality
were observed in the resection
group and the rate of
major complications was 4.5% in
the resection group and 2.0%
in the radiofrequency group
(p=0.101). Four-year overall survival
rates were 74.4% in the
resection group and 66.2% in
the radiofrequency group (p=0.353).
Four-year cumulative HCC recurrence
rates were 56% in the
resection group and 57.1% in
the radiofrequency group (p=0.765).
Local tumor progression was
detected in 20.5% of ablated
patients and in one resected
patient (p<0.001). After propensity
score matching, both survival
and tumor recurrence were still
not significantly different although
a trend towards lower recurrence
was observed in resected
patients. Older age and higher
alpha-fetoprotein levels were
independent predictors of poor
overall survival while older age
and higher alanine-aminotransferase
levels resulted to be
independent factors associated with
higher recurrence rate.
Conclusions
In spite of a higher rate
of local tumor progression,
radiofrequency ablation can provide
results comparable to liver
resection in the treatment of
single hepatocellular carcinoma ?3cm
occurring in compensated
cirrhosis.
