The Early CDT®-Lung antibody blood test plus serial computed tomography scans for test-positives (TPGs) reduces late-stage lung cancer presentation. This study assessed the psychological outcomes of this approach.
Randomized controlled trial (n = 12 208) comparing psychological outcomes 1-12 months post-recruitment in a subsample (n = 1032) of TPG, test-negative (TNG) and control groups (CG).
Compared to TNG, TPG had lower positive affect (difference between means (DBM), 3 months (3m: -1.49 (-2.65, - 0.33)), greater impact of worries (DBM 1m: 0.26 (0.05, 0.47); 3m: 0.28 (0.07, 0.50)), screening distress (DBM 1m: 3.59 (2.28, 4.90); 3m: 2.29 (0.97, 3.61); 6m: 1.94 (0.61, 3.27)), worry about tests (odds ratio (OR) 1m: 5.79 (2.66, 12.63) and more frequent lung cancer worry (OR 1m: 2.52 (1.31, 4.83); 3m: 2.43 (1.26, 4.68); 6m: 2.87 (1.48, 5.60)). Compared to CG, TPG had greater worry about tests (OR 1m: 3.40 (1.69, 6.84)). TNG had lower negative affect (log-transformed DBM 3m: -0.08 (-0.13, -0.02)), higher positive affect (DBM 1m: 1.52 (0.43, 2.61); 3m: 1.43 (0.33, 2.53); 6m: 1.27 (0.17, 2.37)), less impact of worries (DBM 3m: -0.27 (-0.48, -0.07)) and less-frequent lung cancer worry (OR 3m: 0.49 (0.26, 0.92)).
Negative psychological effects in TPG and positive effects in TNG were short-lived and most differences were small.
早期 CDT®-Lung 抗体血液检测联合对阳性检测结果（TPG）的连续计算机断层扫描可降低晚期肺癌的检出率。本研究评估了这种方法的心理结果。
对 TPG、阴性检测结果（TNG）和对照组（CG）亚组（n=1032）中招募后 1-12 个月的心理结果进行随机对照试验（n=12208）。
与 TNG 相比，TPG 的积极影响较低（均值差值，3 个月：-1.49（-2.65，-0.33）），担忧的影响更大（1 个月：0.26（0.05，0.47）；3 个月：0.28（0.07，0.50）），筛查困扰（1 个月：3.59（2.28，4.90）；3 个月：2.29（0.97，3.61）；6 个月：1.94（0.61，3.27）），对测试的担忧（1 个月：OR 5.79（2.66，12.63）），且更频繁地担心肺癌（1 个月：OR 2.52（1.31，4.83）；3 个月：OR 2.43（1.26，4.68）；6 个月：OR 2.87（1.48，5.60））。与 CG 相比，TPG 对测试的担忧更大（1 个月：OR 3.40（1.69，6.84））。TNG 的消极影响较低（log 转换后 3 个月：-0.08（-0.13，-0.02）），积极影响较高（1 个月：1.52（0.43，2.61）；3 个月：1.43（0.33，2.53）；6 个月：1.27（0.17，2.37）），担忧的影响较小（3 个月：-0.27（-0.48，-0.07）），肺癌担忧频率较低（OR 3 个月：0.49（0.26，0.92））。
TPG 的负性心理效应和 TNG 的正性心理效应都是短暂的，且大多数差异较小。
