Screening for cervical cancer precursors with p16/Ki-67 dual-stained cytology: results of the PALMS study.

Background: Pap cytology is known to be more specific but less sensitive than testing for human papillomavirus (HPV) for the detection of high-grade cervical intraepithelial neoplasia (CIN2+). We assessed whether p16/Ki-67 dual-stained cytology, a biomarker combination indicative of transforming HPV infections, can provide high sensitivity for CIN2+ in screening while maintaining high specificity. Results were compared with Pap cytology and HPV testing.

Epidemiology and cost of treatment of genital warts in Spain.

Background: Genital warts (GW) are common and increasing in young people. Ninety percent of GW are due to Human Papillomavirus (HPV) types 6 and 11. The objective of this study was to assess the epidemiology and management costs associated with GW in Spain.

Epidemiology and costs of screening and management of precancerous lesions of the cervix in Spain.

Objective: Oncogenic human papillomaviruses (HPVs) are essential causes of cervical cancer. Screening prevents cancer by detecting precancerous lesions (cervical intraepithelial neoplasia, CIN). Our aim was to assess the annual number of Pap smears and CIN diagnoses in Spain and to estimate associated management costs.

Clinical role of cervical cancer vaccination: when and whom to vaccinate?

The recent development of two highly effective vaccines against persistent infection by the 2 most important types of human papillomavirus (HPV) (16 and 18) and against high grade premalignant lesions (CIN2+) has opened a new scenario for the primary prevention of cervical cancer. The optimum target population for vaccination should be individually defined taking the following into account: 1) the efficacy of the vaccine, 2) the epidemiological context and 3) the vaccination programs available in each country. To achieve the maximum preventive benefits, the vaccine should be administered before the initiation of sexual relations.
