Regression of Cervical Precancerous Lesions and Associated Risk Factors

The aim of this study is to assess the extent of histopathological regression of severe cervical precancerous lesions (CIN 2 and CIN 3); evaluate the proportion of patients who experience the normalization of HPV test and cytology finding among those who were treated conservatively and those who underwent conization; and identify predictive parameters associated with regression. Based on this analysis, a model will be proposed to predict the likelihood of lesion regression.

Urine HPV Testing for Cervical Cancer Screening Among Women Living With HIV in South Africa

The purpose of this study explores the usefulness of urine samples for cervical cancer screening in human immunodeficiency virus (HIV)-infected women. Cervical cancer occurs when women are infected with the human papillomavirus (HPV), which can cause changes in the cells that lead to cervical precancer and, eventually, cervical cancer if untreated. However, urine HPV testing has not been well validated low- and middle-income country settings, with no data available to guide its use in HIV-infected women.
