Abstract:
Objective:To identify underlying reasons for discrepant cases of positive cytology but negative histology.
Methods:Cases with positive cytology and negative histology from 2008 to 2016 were retrieved from Department of Pathology, Obstetrics and Gynecology Hospital of Fudan University. Low grade squamous intraepithelial lesion or higher grade lesions were considered as positive cytology test in the study. Consecutive follow-up biopsies and as well as sites of biopsy were documented for analysis.
Results:Overall positive rate of biopsy followed positive cytology was 74.3%(8 990/12 097). Of the negative biopsies, 675 cases were followed-up with multiple biopsy. Two-hundred and eighty-seven cases (42.5%, 287/675) were confirmed to have lesions. Comparing with those with initial positive biopsiews, patients of the latter group were significantly older and had other specimen types including vaginal biopsy, cone biopsy and hysterectomy. The final histological diagnoses were well correlated with cytological results (Kappa=0.505, P<0.01).
Conclusions:Qualified cervical cytology is complimentary to histological diagnosis. Clinicians should not ignore the positive cytological result prior to a normal histological diagnosis. In contradictory cases, repeated colposcopy and biopsy at extended anatomic sites may reveal additional lesions.
