Eric Topol表示,肿瘤微环境(TME)对癌症治疗与预后至关重要,但此前一直缺乏无创评估方法。如今,一项血液检测技术的突破改变了这一局面("突破"一词他很少使用)。示意图显示,TME包围癌细胞,由免疫细胞、血管(内皮)细胞、成纤维细胞和基质组成。

背景速读

- 肿瘤微环境(TME)是指肿瘤细胞周围的复杂生态系统,包括免疫细胞、血管、成纤维细胞和细胞外基质。它直接影响癌症的进展、转移和治疗响应。 - 传统上评估TME需要组织活检(侵入性手术),且只能获取单个时间点的局部信息,难以全面反映动态变化。 - Eric Topol是知名心脏病学家和基因组学研究者,以严谨著称——他自称"极少用突破这个词",暗示这项血液检测(液体活检)的含金量。 - Paul Graham转发此帖;他是硅谷顶级创业孵化器Y Combinator的联合创始人,常分享科技前沿动态。 - 这项突破的核心是:通过抽血(非侵入性)捕捉血液中来自TME的痕迹(如循环肿瘤DNA、免疫细胞信号等),实现实时、动态监测肿瘤微环境,可能革新癌症诊疗策略。
