癌症治疗受到致癌过程的分子实现的多样性和由此产生的治疗反应的变化的挑战。癌症基因组图谱(TCGA)等项目提供了前所未有的详细分子肿瘤图谱。对这些地图的解释仍然是一个重大挑战。在这里,我们将癌症中改变的数千个遗传和表观遗传特征提炼为约500个选定的功能事件(SFE)。使用这种简化的描述,我们从12种癌症类型中推导出3,299个TCGA肿瘤的分层分类。顶级类别由突变(M类)或拷贝数变化(C类)主导。这种区别在基因组不稳定的极端情况下最为明显,表明存在不同的致癌过程。完整的层次结构显示了肿瘤的多个跨组织组的功能事件模式特征,称为致癌标记类。肿瘤类别中的靶向功能事件提示类别特异性联合治疗。这些结果可能有助于临床试验的定义,以匹配可操作的致癌签名与个性化治疗。
Cancer therapy is challenged by the diversity of molecular implementations of oncogenic processes and by the resulting variation in therapeutic responses. Projects such as The Cancer Genome Atlas (TCGA) provide molecular tumor maps in unprecedented detail. The interpretation of these maps remains a major challenge. Here we distilled thousands of genetic and epigenetic features altered in cancers to ~500 selected functional events (SFEs). Using this simplified description, we derived a hierarchical classification of 3,299 TCGA tumors from 12 cancer types. The top classes are dominated by either mutations (M class) or copy number changes (C class). This distinction is clearest at the extremes of genomic instability, indicating the presence of different oncogenic processes. The full hierarchy shows functional event patterns characteristic of multiple cross-tissue groups of tumors, termed oncogenic signature classes. Targetable functional events in a tumor class are suggestive of class-specific combination therapy. These results may assist in the definition of clinical trials to match actionable oncogenic signatures with personalized therapies.
