Colorectal cancer (CRC) screening using fecal immunochemical tests (FIT) is suboptimal. This multicentre study evaluated an electronic nose (e-nose) for CRC detection in FIT-positive patients, along with reproducibility and external validation. Among 3469 participants (40.1% female, median age 64.3y), CRC was diagnosed in 5.0%; 25.1% had a normal colonoscopy. The e-nose showed poor diagnostic performance (AUC 0.542; sensitivity 39.5%; specificity 68.3%) and low reproducibility (ICC 0.22). Despite high patient acceptability (95.3% willingness-to-repeat), these findings suggest e-nose technology is not yet ready for clinical implementation. Further research is needed to standardise and validate e-nose devices before supplementing current screening methods. Clinicaltrials.gov Identifier NCT03346005 and NCT04357158.
使用粪便免疫化学检测（FIT）进行结直肠癌（CRC）筛查并不理想。这项多中心研究评估了一种电子鼻（e-nose）在FIT阳性患者中检测CRC的情况，以及其可重复性和外部验证。在3469名参与者中（女性占40.1%，中位年龄64.3岁），5.0%被诊断为CRC；25.1%的人结肠镜检查正常。电子鼻的诊断性能较差（AUC为0.542；灵敏度为39.5%；特异性为68.3%）且可重复性较低（ICC为0.22）。尽管患者接受度较高（95.3%愿意再次使用），但这些结果表明电子鼻技术尚未准备好用于临床应用。在补充当前筛查方法之前，需要进一步研究来规范和验证电子鼻设备。Clinicaltrials.gov标识符：NCT03346005和NCT04357158。
