120. 早期癌症检测的问题

from 知为谁 · host 知为谁

文章探讨了早期癌症检测的复杂性与挑战,特别是在新颖的“液体活检”技术背景下。它追溯了细胞游离DNA的发现及其作为癌症检测工具的潜力,但也强调了证明这些测试能真正改善患者预后的困难。文章详细阐述了现有筛查方法的局限性,例如乳房X光检查无法区分肿瘤的侵袭性,并揭示了“先导时间偏倚”和“长度时间偏倚”等统计错觉,这些错觉可能夸大早期检测的益处。此外,它引用了Grail公司开发Galleri测试的案例,该测试旨在从血液中检测多种癌症,讨论了其优点和尚待解决的有效性问题。最终,作者认为真正的进步需要能够降低死亡率的严格随机试验,而非仅仅是更早地发现癌症。内容来源:https://www.newyorker.com/magazine/2025/06/23/the-catch-in-catching-cancer-early
