Abstract

Significance: Large-scale screening inevitably leads to significant financial burdens on the healthcare system, which is a key factor constraining nationwide screenings. The two-step MCED approach not only maintains comparable performance but also substantially alleviates financial strains compared with the direct use of next-generation sequencing-based MCED tests for massive screenings.

在高危人群中进行多种癌症早期检测的成本效益高的两步方法。
在全民癌症筛查中,需要关注三个关键问题:确定的癌症病例数、假阳性病例数和费用。OncoSeek是一种多种癌症早期检测(MCED)测试,使用7种蛋白质肿瘤标志物(PTMs)和人工智能(AI)。SeekInCare是一种MCED测试,通过浅全基因组测序从无细胞DNA中整合了7种ptm和4种癌症基因组特征。在两步的方法中,使用OncoSeek进行初始筛选,然后使用SeekInCare作为OncoSeek检测呈阳性的个体的二次测试。我们模拟了500万年龄≥50岁、癌症发病率为1.9%的成年人的筛查。在91.0%的特异性下,OncoSeek有441450个假阳性,而使用两步法可将假阳性显著减少到34335个(0.7%)。虽然SeekInCare和Galleri发现的癌症病例(分别为32015例和27455例)比两步MCED(21280例)多,但它们的总成本分别达到37.5亿美元和47.45亿美元。由于两步法的阳性预测值(PPV)(38.3%)与SeekInCare(27.7%)和Galleri(38.3%)相当,成本分别降低了5.3倍和6.6倍,总计成本为7.136亿美元,每人筛查成本为143美元。SeekInCare和Galleri的每例癌症检测成本分别为117,133美元和172,828美元,分别比两步MCED(33,534美元)高3.5倍和5.2倍。两步法不仅大大减少了假阳性,而且大大降低了筛查成本,使其成为一种具有成本效益的全民癌症筛查策略。
