Cervical screening adjuncts: recent advances

Am J Obstet Gynecol. 1998 Aug;179(2):544-56. doi: 10.1016/s0002-9378(98)70393-x.


In an effort to reduce the false-negative rate of cervical cytologic findings, several new technologies have recently evolved. Automated cytologic testing (PapNet, AutoPap 300 QC) proposes to rescreen negative conventional cytologic findings to identify smears likely to be false negative. Fluid-based monolayers (ThinPrep, CytoRich) propose to reduce the false-negative rates by optimizing the collection and preparation of cells. Human papillomavirus deoxyribonucleic acid testing by Hybrid Capture has been proposed for a variety of screening and triage roles. Visual screening after application of acetic acid is done by cervicography by use of a photographic technique, whereas in speculoscopy the screening is done by direct visualization of the cervix by the primary care provider. Polarprobe uses biophysical parameters and a computer algorithm to give an instantaneous prediction of the likelihood of cervical disease. Each of these techniques, as well as the clinical experience with them, is reviewed. Current and possible future uses are discussed with regard to both clinical usefulness and cost-effectiveness.
