We present an extensive assessment of mutation burden through sequencing analysis of >81,000 tumors from pediatric and adult patients, including tumors with hypermutation caused by chemotherapy, carcinogens, or germline alterations. Hypermutation was detected in tumor types not previously associated with high mutation burden. Replication repair deficiency was a major contributing factor. We uncovered new driver mutations in the replication-repair-associated DNA polymerases and a distinct impact of microsatellite instability and replication repair deficiency on the scale of mutation load. Unbiased clustering, based on mutational context, revealed clinically relevant subgroups regardless of the tumors' tissue of origin, highlighting similarities in evolutionary dynamics leading to hypermutation. Mutagens, such as UV light, were implicated in unexpected cancers, including sarcomas and lung tumors. The order of mutational signatures identified previous treatment and germline replication repair deficiency, which improved management of patients and families. These data will inform tumor classification, genetic testing, and clinical trial design.

人类癌症超突变的综合分析。

我们通过对来自儿童和成人患者的超过 81,000 个肿瘤进行测序分析,对突变负荷进行了广泛的评估,其中包括由化疗、致癌物或种系改变引起的超突变肿瘤。在以前与高突变负荷无关的肿瘤类型中检测到超突变。复制修复缺陷是一个主要因素。我们发现了复制修复相关 DNA 聚合酶中的新驱动突变,以及微卫星不稳定性和复制修复缺陷对突变负荷规模的明显影响。基于突变背景的无偏聚类揭示了临床相关的亚组,无论肿瘤的组织来源如何,突出了导致超突变的进化动力学的相似性。紫外线等诱变剂与肉瘤和肺癌等意想不到的癌症有关。突变特征的顺序确定了先前的治疗和种系复制修复缺陷,从而改善了对患者和家庭的管理。这些数据将为肿瘤分类、基因检测和临床试验设计提供信息。
