超声检查推荐用于肝硬化背景下肝细胞癌患者的监测。此监测在降低死亡率的有效性方面存在争议,而且几乎没有可用的信息表明监测对于患者的危害。本研究的目的是对此监测的益处和危害进行评估。为了模拟进入监测的患者预后,我们建立了马尔可夫模型(Markov model)。通过超声识别肝脏局灶性病变后,采用EASL-EORTC召回策略对进一步的调查进行了定义。研究中,每1000名患者在五年内
Ultrasonography is recommended for the monitoring of patients with hepatocellular carcinoma in the setting of cirrhosis. This monitoring is controversial in terms of reducing the effectiveness of mortality, and there is little information available to indicate the hazards of monitoring for the patient. The purpose of this study is to evaluate the benefits and hazards of this monitoring. In order to simulate the prognosis of the patients entering the monitoring, we established the Markov model. After the diagnosis of hepatic focal lesions by ultrasound, further investigations were defined using the EASL-EORTC recall strategy. In the study, every 1000 patients within five years
