Nat Commun:综合药物基因组学揭示鼻咽癌亚型特异性治疗反应

2021-05-27 xiaozeng MedSci原创

鼻咽癌(NPC)作为一种恶性头颈癌,其发病率很高

鼻咽癌(NPC)作为一种恶性头颈癌,其发病率很高,通常在一些特定的地区发生,包括东南亚、北非、中国南方省份、香港和台湾地区。在2015年,中国共发现了60,600例新的NPC病例以及34,100例死亡病例。

NPC涉及许多危险因素,包括环境因素、EBV(爱泼斯坦-巴尔病毒)感染、吸烟、饮食和个人生活习惯等。然而,这些因素如何导致NPC的形成却知之甚少。

基因组变异和家族风险是造成鼻咽癌的另一个重要原因,与其他头颈癌不同,NPC的无症状性是主要挑战,这阻碍了该疾病的早期诊断。这也导致许多患者确诊时已处于疾病的晚期,这也降低了患者的整体生存率(OS)。


目前一项新型的NPC预后组织病理学分类系统根据疾病的形态特征将NPC分为了四种亚型:上皮癌(EC)、肉瘤样癌(SC)、混合肉瘤样上皮癌(MSEC)和鳞状细胞癌(SCC),这些NPC亚型可能与患者的预后相关。

鼻咽癌亚型的组织学和分子景观

在该研究中,研究人员通过整合的药物基因组学分析,发现NPC亚型保持着独特的分子特征、药物反应性和分级放射敏感性。研究人员发现,上皮癌(EC)亚型的特征在于微管聚合作用的激活以及有丝分裂纺锤体检查点相关基因的缺失,而肉瘤样癌(SC)和混合型肉瘤样上皮癌(MSEC)的亚型则表现为丰富的上皮-间质转化(EMT)进程和促进侵袭基因的表达升高,这与其形态特征密切相关。


此外,基于患者的类器官(PDO)的药物测试可用于确定潜在的亚型特异性治疗方案,SC和MSEC亚型对微管抑制剂敏感,而EC亚型则对EGFR抑制剂更敏感,该抑制剂可与放疗联合以增强效果。组合放化疗(CRT)筛查显示,放射敏感性较低的患者可采用有效的CRT疗法进行治疗。

CRT筛查揭示联合治疗可提高治疗效果

总而言之,该研究结果提供了一个个性化的精确肿瘤学例子,通过应用综合药物基因组学方法指导NPC亚型的治疗策略。
