ObjectivesTo evaluate the efficacy of Optical Coherence Tomography (OCT) for detecting cervical lesions in women with minor abnormal cytology results (atypical squamous cells of undetermined significance (ASC-US) and low-grade squamous intraepithelial lesion (LSIL)).MethodsA prospective study was conducted at gynecologic clinic from Mar 2021 to Sep 2021.The recruited women with cervical cytological findings of ASC-US or LSIL were inspected with OCT before colposcopy-directed cervical biopsy.

The diagnostic performance of OCT, AEG HGB75420YM Gas Hob alone and in combination with high-risk human papillomavirus (hrHPV) testing were evaluated to detect cervical intraepithelial neoplasia of grade 2 or worse (CIN2+)/CIN3 NADH or worse (CIN3+).The rate of colposcopy referral and the immediate risk of CIN3+ of OCT were calculated.ResultsA total of 349 women with minor abnormal cervical cytology results were enrolled.

For detection of CIN2+/CIN3+, the sensitivity and NPV of OCT were lower than those of hrHPV testing (CIN2+: 71.3% vs.95.

4%, 89.0% vs.91.

1%, P ConclusionsOCT alone or combination with hrHPV testing shows good performance for detecting CIN2+/CIN3+ in patients with ASC-US/LSIL cytology.OCT is an effective method for colposcopy triage in women with hrHPV-positive ASC-US and hrHPV-negative LSIL cytology.
