HPV testing in the evaluation of the minimally abnormal Papanicolaou smear.
Minor cytologic abnormalities of the cervix, such as atypical squamous cells of undetermined significance (ASCUS), are vastly more common than high-grade squamous intraepithelial lesions or invasive cancer. Current guidelines for the management of ASCUS include repeating the Papanicolaou (Pap) smear at specific intervals, referring all patients for colposcopy or using an adjunctive test such as hybrid capture human papillomavirus (HPV) testing or cervicography. The usefulness of the Pap smear is limited by its considerable false-negative rate and its dependence on clinician and laboratory performance. Colposcopy is a highly sensitive procedure, but many patients with ASCUS have normal colposcopic findings. The hybrid capture test not only measures quantitative HPV load but also detects both oncogenic and nononcogenic HPV types, thereby increasing the probability that serious cervical disease is not missed. Hybrid capture sampling is simple to perform, and positive results are strongly associated with cervical dysplasia. HPV testing in women with ASCUS can be used as an adjunctive test to identify those with HPV-associated disease; it can also serve as a quality assurance measure. Together, repeat Pap smears and HPV testing should identify most patients with underlying cervical dysplasia. Combined testing may also minimize the number of unnecessary colposcopic examinations in women who have no disease.
