Human papillomavirus (HPV) is a virus from the papillomavirus family that is capable of infecting humans. Some types of HPVs cause warts, while others can lead to cancers of the cervix, vulva, vagina, penis, oropharynx and anus. High-risk human papillomavirus (hr HPV) has been detected in almost all cervical squamous cell carcinomas and adenocarcinomas. All patients examined by colposcopy. Cervical swab is routinely done and patients are screened with both HPV DNA by Real Time Polimerase Chain Reaction (RT PCR) testing and Pap testing. Pictures obtained by colposcopy were examined by indirect Bi-Digital O-Ring Test (BDORT) by using reference control substance (RCS): HPV 16, HPV 18, and Integrin α5 β1. BDORT was developed by Prof. Omura Y. of New York and received U.S. patent in 1993. For detection of HPV DNA we used RT PCR and standard Qiagen method which detect 18 types (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68, 6, 11, 42, 43, 44) of HPV from smear. From 63 patients where is BDORT indicated presence of HPV, in 49 patients (77.8%) RT PCR confirmed presence of HPV. From 63 patients in 54 patients (85.7%), we detected, by colposcopic exam, some kind of lesions associated with HPV infection. Results obtained by RT PCR: one type (1/18) of DNA HPV in 25 patients (51.02%), 2 types (2/18) in 15 patients (30.61%) and 3 types (3/18) in 9 patients (18.37%). Although BDORT results usually have higher sensitivity and detection rate is much higher, it can be used together with RT PCR in detection of HPV and cervical lesions associated with HPV infection.

Objective: We aimed to assess the coverage of a Human Papillomavirus (HPV) screening program for each of the 32 federal states of Mexico, as well as the spatial patterns for HPV infections from 2013 to 2019.

Methods: We conducted an exploratory, ecological study on data from a national health program in Mexico during 2013-2019. Adjusted rates per 100,000 females aged 25-64 years were estimated and georeferenced at the national and state level to assess the coverage of the screening program and positive detections of HPV infections.

Background: Cervical cancer is the fourth most common cancer worldwide in females. This occurs primarily due to the infection of high-risk Human Papilloma Virus (HPV), although in advanced stages it requires support from host cellular factors. BRN3A is one such host cellular factors, whose expression remains high in cervical cancers and upregulates tumorigenic HPV gene expression.

Background: While detection of circulating tumor DNA (ctDNA) weeks after surgery is linked to recurrence for other solid tumors, the optimal time point for ctDNA assessment as a prognostic biomarker following chemoradiation for anal cancer is undefined.

Methods: Patients with stages I-III anal cancer treated with chemoradiation between 12/2020-5/2024 were evaluated for HPV ctDNA status at baseline, at the end of chemoradiation, and during surveillance using a droplet digital HPV ctDNA PCR assay targeting HPV E6 and E7 oncogenes for 13 oncogenic HPV types. Median recurrence-free survival (RFS) according to HPV ctDNA status was estimated via Kaplan-Meier and compared using a log-rank test.

In cervical cancer screening, cytology is used as a triage test to refer high-risk human papillomavirus (HR-HPV)-positive women for colposcopy, but its accuracy is inadequate. The present study aimed to demonstrate that the presence of atypical cells with large vacuoles in the cytoplasm of parabasal cells, referred to as vacuolated parabasal cells (VPCs), which are observed in the Pap smears of HPV-positive women, is associated with specific HPV genotypes. Among 2175 patients, 310 with a single HR-HPV infection and cytological diagnosis of high-grade squamous intraepithelial lesions (HSIL) or atypical squamous cells not excluding HSIL (ASC-H) were included, of which 86 were infected with HPV16.

Background: This study was conducted to evaluate screening procedures for anal high-grade squamous intraepithelial lesions (HSILs) with anal liquid-based cytology (aLBC) and biomarkers to identify candidates for high-resolution anoscopy (HRA).

Methods: This cross-sectional study included men who have sex with men with HIV. Participants underwent HRA, aLBC, and biomarker testing.
