Prasad指出即便对长期吸烟者,肺癌CT筛查证据也薄弱,NLST后续数据和NELSON试验均未显示全癌死亡率下降。
即使在最可能获益的人群——长期吸烟者中,肺癌CT筛查也存在争议。Pinsky关于NLST的后续发表中,它未能维持死亡率获益。NELSON试验是一场灾难,方案一改再改,却没有降低全癌死亡率。原文 (en)
Even in a population most likely to derive benefit- long time smokers-- ct screening for lung cancer is disputed. It has failed in a follow-up publication by Pinsky regarding the nlst to sustain a mortality benefit. The Nelson trial is a disaster. It's protocol amendment after protocol amendment with no all cancer mortality reduction.
