Primary liver cancer is one of the common cancers in the world and with extremely high morbidity and mortality. This paper details the current epidemiology of primary liver cancer, population attributable fractions and associated risk factors in China. In this paper, we found that hepatitis B virus and hepatitis C virus are still the main risk factors for the development of primary liver cancer by searching the databases such as PubMed, Web of Science, and CNKI. With hepatitis B virus vaccination and antiviral treatment, the incidence of primary liver cancer in China has slightly decreased, but the incidence of primary liver cancer caused by metabolic factors such as diabetes, obesity and non-alcoholic fatty liver disease is gradually increasing; smoking and alcohol consumption are also important risk factors. This article summarizes the epidemiological characteristics and risk factors of primary liver cancer, which can provide practical evidence-based medicine evidence for the development of preventive and control measures for primary liver cancer.

原发性肝癌是世界上常见的恶性肿瘤之一，具有较高的发病率和死亡率。本文详述了目前我国原发性肝癌的流行病学情况、人群归因分值及其相关危险因素。本文通过检索PubMed、Web of Science、中国知网等数据库发现，乙型肝炎病毒和丙型肝炎病毒仍是原发性肝癌发病的主要危险因素。随着乙型肝炎病毒疫苗接种以及抗病毒治疗，我国原发性肝癌的发病率略有下降，但代谢性因素如糖尿病、肥胖和非酒精性脂肪性肝病等引起的原发性肝癌的发病率正逐步上升；吸烟、饮酒等也是重要的危险因素。本文综述了原发性肝癌的流行病学特点及危险因素，可为制订原发性肝癌防控措施提供切实有力的循证医学证据。
