摘要

虽然透明细胞肾细胞癌（ccRCC）遗传进化的关键方面及其临床意义已被充分记录，但遗传特征如何与表型和肿瘤微环境（TME）共同进化仍然难以捉摸。在这里，通过对来自79名TRACERx肾脏研究患者的243个样本的基因组-转录组学联合分析，我们确定了普遍的非遗传性肿瘤内异质性，其中超过40%的非遗传改变。通过整合肿瘤转录组和系统发育结构，我们观察到特定表型性状的趋同进化，包括细胞增殖、代谢重编程和高非整倍体中推测的cGAS-STING抑制因子的过表达。我们还揭示了肿瘤和T细胞库之间的共同进化，以及TME从抗肿瘤状态到免疫抑制状态的纵向转变，这与获得复发性晚期ccRCC驱动因子9p丢失和SETD2突变有关。我们的研究揭示了ccRCC的临床相关和迄今未被充分认识的非遗传进化模式

Tracking non-genetic evolution from primary to metastatic ccRCC: TRACERx Renal

While the key aspects of genetic evolution and their clinical implications in clear cell renal-cell carcinoma (ccRCC) are well-documented, how genetic features co-evolve with the phenotype and tumor microenvironment (TME) remains elusive. Here, through joint genomic-transcriptomic analysis of 243 samples from 79 patients recruited to the TRACERx Renal study, we identify pervasive non-genetic intratumor heterogeneity, with over 40% not attributable to genetic alterations. By integrating tumor transcriptomes and phylogenetic structures, we observe convergent evolution to specific phenotypic traits, including cell proliferation, metabolic reprogramming and overexpression of putative cGAS-STING repressors amid high aneuploidy. We also uncover a co-evolution between the tumor and the T cell repertoire, as well as a longitudinal shift in the TME from an anti-tumor to an immunosuppressive state, linked to the acquisition of recurrently late ccRCC drivers 9p loss and SETD2 mutations. Our study reveals clinically-relevant and hitherto underappreciated non-genetic evolution patterns in ccRCC
