A comparison of uterine cervical cytology and biopsy results: indications and outcomes for colposcopy.
BACKGROUND
There is some debate in the literature over the proper approach to the patient with a mildly abnormal cervical cytologic finding. One current approach for handling low-grade cytologic abnormalities is to perform colposcopy and biopsy if atypia, human papillomavirus (HPV) changes, or mild dysplasia is noted on cytologic examination. If a Papanicolaou (Pap) smear shows inflammation without atypia, the test is repeated after 3 months, and if inflammation does not clear, colposcopy is performed. This study was undertaken to determine whether the above recommendations are appropriate.


METHODS
In a 1-year period, 125 patients underwent colposcopy and biopsy. Results were reviewed and compared.


RESULTS
Of 47 patients with smears showing human papillomavirus (HPV) changes, 68% had a higher grade abnormality (dysplasia) on biopsy; 15% had moderate or severe dysplasia. Of eight patients with atypia, 63% had dysplasia on biopsy. Of 41 patients with mild dysplasia on Pap smear, 37% had moderate dysplasia or higher grade disease on biopsy. Of nine patients with persistent inflammation on cytologic examination, biopsy showed 56% with inflammation, 33% with mild dysplasia, and 11% normal.


CONCLUSIONS
Patients who presented with minimal Pap smear abnormalities such as HPV changes or atypia are likely to have a worse histologic diagnosis, with approximately two thirds showing dysplasia. Patients with persistent inflammation are less likely to have dysplasia. The results support our aggressive approach toward minimally abnormal smears and our consideration of inflammation without atypia as a separate and lower risk category.
