The study aimed to determine if the difference in cervical epithelium brightness, as measured by optical coherence tomography (OCT), has potential as a distinguishing characteristic of normal, low-grade, high-grade (cervical intraepithelial neoplasia 2+), and cancer histological findings.
Information from 476 women was available for analysis. Demographic information was collected through in-person interview. All participants were human papillomavirus positive and/or had abnormal cytological finding and underwent colposcopy or unaided visual inspection and examination by OCT by quadrant. All women had a minimum of 4 OCT-matched cervical biopsies and endocervical curettage. Two sample t tests were used to measure differences in OCT image brightness by histological grades.
Mean OCT image brightness differed significantly between each preinvasive histological grade and invasive cancer (p < .01 for all comparisons). Brightness as measured by OCT was also able to differentiate between squamous metaplasia and cervical intraepithelial neoplasia 3/cancer; p values were .004 and .003, respectively.
Epithelial brightness is an important component of cervical epithelium diagnosis by OCT, and we plan to add it to our diagnostic mathematical algorithm in all future versions of OCT software.
A quantitative optical imaging method was found to be effective in identifying high-grade preinvasive and early invasive cervical carcinoma.
