概括
从多种癌症早期检测 (MCED) 血液测试中获得虚假阳性结果的女性患癌症的风险较低. 使用成像的进一步调查证实没有癌症,长期随访显示新癌症的发病率很低.
科学领域:
- 在瘤学瘤学.
- 医学诊断 医学诊断 医学诊断
- 癌症查 癌症查
背景情况:
- 标准护理 (SoC) 癌症查仅涵盖四种癌症类型,错过了许多与癌症相关的死亡.
- 多种癌症早期检测 (MCED) 血液测试为更广泛的癌症查提供了潜力.
- 对于具有虚假阳性 (FP) MCED 结果的个体的长期结果需要评估.
研究的目的:
- 在没有初始癌症诊断的情况下,在阳性MCED血液测试 (CancerSEEK) 后评估基于成像的诊断工作流程的性能.
- 为了评估具有虚假阳性 (FP) MCED结果的参与者的长期癌症风险.
- 从DETECT-A试验中分析FP队列中的临床结果和癌症发病率.
主要方法:
- 在一年内对98名DETECT-A参与者进行前性分析,他们有阳性CancerSEEK测试和阴性18-F-FDG PET-CT/对比度增强CT成像.
- 医疗记录审查,研究相互作用和调查,以追踪癌症发病率,治疗和结果,直到2023年8月.
- 从确定FP状态开始,随访时间的中位数为3.6年.
主要成果:
- 98名参与者中有95人 (96.9%) 具有FP结果,仍然没有癌症.
- 在随访期间,诊断出三种突发性癌症 (一个卵巢癌,两个乳腺癌).
- 在FP后确定的癌症年发病率为1.0% (95%CI:0.2%-2.8%).
结论:
- 阳性MCED测试 (CancerSEEK) 和阴性成像检查结果的参与者在随后的几年中患癌症的风险较低.
- 在阳性MCED测试后涉及成像的诊断工作流程有效地识别了没有癌症的个体.

In healthcare diagnostics, laboratory tests play a crucial role in identifying and diagnosing a wide range of medical conditions. However, interpreting test results is not always straightforward. An abnormal test result does not always confirm the presence of a disease, just as a normal result does not guarantee its absence. To assess the reliability of these diagnostic tools, healthcare practitioners rely on two key statistical indicators: sensitivity and specificity.

Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...
