Comparison of HPV test <i>versus</i> conventional and automation‐assisted Pap screening as potential screening tools for preventing cervical cancer

Abstract

Pap smear, as a screening test, is very different from HPV DNA detecting test HR HC 2. If cutoff LSIL or more severe lesions is used, primary Pap smear is clearly more specific than HR HC2, but markedly less sensitive. Due to high relative sensitivity of the HPV, only very few histologically confirmed high grade lesions would be detected among HPV negatives using simultaneous cytology. On the other hand, using HPV DNA test alone would lead to multifold amounts of referrals for colposcopy. A posterior Pap smear assessment among HPV positives might be helpful in increasing sensitivity and specificity of screening and defining those who need an immediate referral or treatment. We plan to incorporate primary HR HPV DNA test with posterior Pap smear reading of HPV positives into our ongoing randomised prospective multiarm trial evaluating new techniques in organised screening for cervical cancer in Finland.
