目的:研究肝癌患者发病的诱因和高危人群预防的检查方法。方法:使用统计法获得肝癌的诱因,通过临床实践掌握预防肝癌疾病的检查方法。结果:引起患者发生肝癌的原因主要与霉变食物、慢性肝病、肝硬化、药物作用、免疫衰退以及性别等因素有关,对高危人群的检查方法主要是对其进行定期、定位和定性检查。结论:重视肝癌的发病诱因,远离危险因素并对高危者进行“定期”“定性”与“定位”联合检测,则能及时发现高危人群里的无症状早期肝癌,及早进行药物干预,对延长病人的生存期有重要的临床价值。 Objective: To study the causes of liver cancer patients and prevention of high-risk groups check the method. Methods: To obtain the cause of liver cancer using statistical methods, through clinical practice to master the prevention of liver cancer disease inspection methods. Results: The main causes of liver cancer in patients with mildew food, chronic liver disease, liver cirrhosis, drug effects, immune decline and gender and other factors related to high-risk groups mainly for its inspection methods for its regular, location and qualitative examination. CONCLUSIONS: To attach importance to the predisposing factors of HCC and avoid the risk factors and carry out joint detection of high-risk patients with “periodic”, “qualitative” and “positioning”, we can detect asymptomatic early-stage liver cancer in high- Drug intervention, to extend the survival of patients with important clinical value.
