Non-alcoholic fatty liver disease (NAFLD), one of the most common causes of liver disease, is an increasingly common cause of hepatocellular carcinoma (HCC). Several demographic, clinical, and genetic factors contribute to HCC risk in NAFLD patients, which may inform risk stratification scores. Proven efficacious approaches to primary prevention approach in patients with non-viral liver disease remain an area of need. Semi-annual surveillance is associated with improved early tumor detection and reduced HCC-related mortality; however, patients with NAFLD have several challenges to effective surveillance, including under-recognition of at-risk patients, low surveillance utilization in clinical practice, and lower sensitivity of current tools for early-stage HCC detection. Treatment decisions are best made in a multidisciplinary fashion and are informed by several factors including tumor burden, liver dysfunction, performance status, and patient preferences. Although patients with NAFLD often have larger tumor burden and increased comorbidities compared to counterparts, they can achieve similar post-treatment survival with careful patient selection. Therefore, surgical therapies continue to provide a curative treatment option for patients diagnosed at an early stage. Although there has been debate about the efficacy of immune checkpoint inhibitors in patients with NAFLD, current data are insufficient to change treatment selection based on liver disease etiology.
非酒精性脂肪性肝病(NAFLD)是肝病最常见的病因之一,也是肝细胞癌(HCC)日益常见的病因。一些人口统计学、临床和遗传因素会增加NAFLD患者患HCC的风险,这可能有助于风险分层评分。对于非病毒性肝病患者,行之有效的一级预防方法仍是一个有待解决的领域。半年一次的监测与提高早期肿瘤检测率和降低HCC相关死亡率相关;然而,NAFLD患者在有效监测方面存在一些挑战,包括对高危患者认识不足、临床实践中监测利用率低以及当前早期HCC检测工具的敏感性较低。治疗决策最好以多学科方式做出,并受多种因素影响,包括肿瘤负荷、肝功能障碍、体能状态和患者偏好。尽管与其他患者相比,NAFLD患者通常肿瘤负荷更大且合并症更多,但通过仔细选择患者,他们可以获得相似的治疗后生存率。因此,手术治疗仍然为早期诊断的患者提供了一种治愈性的治疗选择。尽管关于免疫检查点抑制剂在NAFLD患者中的疗效存在争议,但目前的数据不足以根据肝病病因改变治疗选择。
