International guidelines suggest ultrasound surveillance for hepatocellular carcinoma (HCC) early diagnosis in liver cirrhosis (LC) patients, but 40% of nodules 2 cm escape detection. We investigated the existence of an ultrasound pattern indicating a higher risk of developing HCC in patients under surveillance. 359 patients with LC (Child-Pugh A-B8) underwent ultrasound screening (median follow-up 54 months, range 12-90 months), liver function tests, alpha-fetoprotein assay, and portal hypertension evaluation. Echo patterns were homogeneous, bright liver, coarse, coarse small nodular pattern, and coarse large nodular pattern. During follow-up 13.9% developed HCC. At multivariate analysis using Cox's model alpha-fetoprotein, coarse large nodular pattern, portal hypertension, and age were independent predictors of HCC development. Kaplan-Meier estimates of HCC cumulative risk in relation to the baseline echo patterns showed risk of 75% in coarse large nodular pattern patients, 23% coarse small nodular pattern, 21% coarse pattern, 0% homogeneous, and bright liver echo patterns (log-rank test = 23.6, < 0.001). Coarse large nodular pattern indicates a major risk factor for HCC as 40.7% of patients with this pattern developed HCC. Homogeneous and bright liver echo patterns and the absence of portal hypertension were not related to HCC. This observation could raise the question of possibly modifying the follow-up timing in this subset of patients.
国际指南建议对肝硬化(LC)患者进行超声监测以早期诊断肝细胞癌(HCC),但仍有 40%的 2cm 结节漏诊。我们研究了在接受监测的患者中是否存在一种超声模式表明 HCC 发生风险较高。359 例 LC(Child-Pugh A-B8)患者接受了超声筛查(中位随访 54 个月,范围 12-90 个月),包括肝功能检查、甲胎蛋白检测和门静脉高压评估。回声模式为均匀性亮肝、粗糙、粗小结节模式和粗大结节模式。在随访期间,13.9%的患者发展为 HCC。多变量 Cox 模型分析显示,甲胎蛋白、粗大结节模式、门静脉高压和年龄是 HCC 发生的独立预测因素。Kaplan-Meier 估计与基线回声模式相关的 HCC 累积风险显示,粗大结节模式患者 HCC 的风险为 75%,粗小结节模式为 23%,粗糙模式为 21%,均匀性亮肝回声模式为 0%(对数秩检验=23.6,<0.001)。粗大结节模式是 HCC 的一个主要危险因素,因为 40.7%的此类患者发生了 HCC。均匀性亮肝回声模式和无门静脉高压与 HCC 无关。这一观察结果可能引发人们对这部分患者随访时间进行调整的疑问。
