BOSCH, F. Xavier. Epidemiology of human papillomavirus infections: new options for cervical cancer prevention. Salud pública Méx [online]. 2003, vol.45, suppl.3, pp.326-339. ISSN 0036-3634.

In the last two decades, the cervical cancer puzzle has become a coherent description that includes the identification of human papillomavirus (HPV) as the sexually transmitted etiologic agent and the characterization of the major determinants of HPV acquisition. Triage studies have consistently shown that HPV testing is more sensitive that repeated cytology in identifying underlying high-grade lesions in women with atypical scamous cells of undetermined significance (ASCUS). Studies that reflect primary screening conditions have shown that the sensitivity of HPV tests is higher than standard cytology in detecting high-grade lesions whereas the specificity is similar only in women aged 30-35 and above. HPV vaccines have an intrinsic attraction as a preventive strategy in populations with limited resources. However, vaccines designed to widespread use are still in development and testing phases. Time is ripe for exploring in depth the clinical implications of current achievements and to devise novel strategies for the prevention of cervical cancer.
