摘要

Deep learning (DL) systems could improve diagnostic accuracy and efficiency in detecting cervical atypia, but their effectiveness remains insufficiently explored. This multicentre, randomised crossover trial evaluated the clinical utility of a DL system in cervical cytopathology. A total of 1,920 women aged 18 years or older undergoing liquid-based cytology for cervical cancer screening were included, and their slides were digitized and randomly assigned (1:1) to two reading sequences. Four non-expert cytopathologists with 1–3 years of experience assessed slides using DL assistance for one group and manual microscopy for the other, and then switched roles after a four-week washout period. Each slide was evaluated twice in a randomly shuffled order. DL significantly improved sensitivity (85.7% vs 71.3%, p < 0.001), with a difference of 14.3% (95% CI: 7.6% to 21.1%), exceeding the 5% superiority margin. Specificity was comparable (86.5% vs 85.1%, p = 0.238), and non-inferiority was supported, as the lower limit of the 95% CI for the difference (1.4%; 95% CI: −1.0% to 3.8%) was above the pre-specified margin of −5%. Reading time was markedly reduced with DL (175 seconds vs 31 seconds, p < 0.001). DL assistance could enhance both sensitivity and efficiency while rigorously preserving specificity in cervical cytology interpretation. Trial registration: ChiCTR2300078722.
