樊嘉向记者介绍，肝癌在中国的发病率高，新发病例接近40万，其中约70%至80%患者在发现时已属中晚期，丧失手术机会。“肝癌治疗面临多重挑战，其复杂性源于高度异质性，缺乏统一的基因突变模式，这增加了彻底根治的难度。”他指出乐竞体育app手机版登录，深入理解肝癌的发生、发展、复发及转移机制，需依赖于基础研究和分子生物学的进展。

他表示，针对具有高危因素的肝癌患者，如乙型肝炎感染者、肝硬化患者及有家族史的个体，应定期进行筛查。目前，血清学诊断和胶原蛋白检查虽价格相对便宜，但敏感性和特异性有限，约60%的准确性。近年来，通过国际合作与研发，已推出敏感性和特异性超过80%的微小核糖核酸诊断试剂盒，为高危人群提供了更准确的筛查手段。
