The HPV Persistence and Progression (PaP) Cohort at Kaiser Permanente Northern California
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: * In most women, HPV infection does not cause symptoms and the infection goes away on its own. In a small percentage of women, the HPV infection does not go away and sometimes can result in cervical precancer or cancer. * There are several different types of HPV. A better understanding of which types are related to cervical precancer and cancer may help guide doctors in clinical management of women who test positive for HPV and better understand why some women develop disease while others do not. Objectives: * To determine whether certain types of HPV are more risky than others and if so, whether they warrant separate detection in screening for cervical precancer and cancer. * To determine if lasting infection by different HPV types carry different risk of cervical precancer and cancer. * To determine what viral and genetic factors influence the development of cervical precancer and cancer. * To evaluate new HPV tests and new biomarkers of cervical cancer risk. Eligibility: -Women 30 years of age and older who are in the cervical cancer screening program at the Kaiser Permanente health plan in Northern California. Women who tested positive for HPV and a random sample of women who tested negative for the virus are included. Design: -Data about participants genetic background and the type of carcinogenic HPV with which they are infected are analyzed.
