Liver Int:慢性肝病肝细胞癌晚期复发的病理预测因素

2021-03-01 MedSci原创 MedSci原创

肝细胞癌(HCC)晚期复发被认为是慢性肝炎后的新发肝癌。

肝细胞癌(HCC)晚期复发被认为是慢性肝炎后的新发肝癌。

本研究调查了可用于建立了预测晚期HCC复发(根治性切除术2年后)的诺模图的临床病理和分子因素。

训练和验证队列均纳入了接受根治性切除的以乙肝为主要病因的肝癌患者。评估了临床病理特征,包括小叶和门静脉周围炎症活动、纤维化和肝细胞改变。利用95个非肿瘤性肝组织的反相蛋白质阵列鉴定了与晚期复发相关的基因编码的蛋白质。此外,还检测了磷酸化信号转导和转录激活剂3(pSTAT3)、纤溶酶原激活物抑制物-1(PAI-1)、磷酸化细胞外信号调节激酶1/2(pERK1/2)和脾脏酪氨酸激酶(SYK)的免疫表达水平。

训练组和验证组分别纳入了402位和243位肝癌患者,晚期复发率分别为18%(74/402)和19%(47/243)。肝硬化、中/重度小叶炎性活动及与肝细胞损伤和再生相关的pSTAT3、pERK1/2和SYK蛋白表达与晚期复发独立相关,其优势比(95%CI)分别为2.0(1.2~3.3)、21.1(4.3~102.7)和6.0(2.1~17.7)(均P<0.05)。

基于这些变量的诺模图在训练和验证队列中都显示出很高的可靠性(Harrell C指数:0.701[95% CI 0.64~0.76]和0.716[0.64~0.79])。

综上,pSTAT3、pERK1/2和SYK免疫表达与高小叶炎性活动和肝硬化(纤维化)相结合可预测晚期HCC复发
