Cost-Effectiveness of CT Screening in the National Lung Screening Trial

We estimated that screening for lung cancer with low-dose CT would cost 81, 000 per QALY gained, but we also determined that modest changes in our assumptions would greatly alter this figure. The determination of whether screening outside the trial will be cost-effective will depend on how screening is implemented.
