OBJECTIVE To evaluate the reproducibility and accuracy of the HPV16/18-E6 test. METHODS The study population was comprised of 448 women with a previously abnormal Pap who were referred to the Barretos Cancer Hospital (Brazil) for diagnosis and treatment. Two cervical samples were collected immediately before colposcopy, one for the hr-HPV-DNA test and cytology and the other for the HPV16/18-E...

objective(s):  infection by high-risk papillomavirus is regarded as the major risk factor in the development of cervical cancer. recombinant dna technology allows expression of the l1 major capsid protein of hpv in different expression systems, which has intrinsic capacity to self-assemble into viral-like particles (vlp). vlps are non-infectious, highly immunogenic and can elicit neutralizing a...

Background: With the implementation of primary high-risk human papillomavirus (hrHPV) screening in Netherlands, an increase was observed number unnecessary referrals (?Cervical Intraepithelial Neoplasia (CIN) 1) to colposcopy. We aimed investigate which alternative triage strategies safely reduce HPV-based cervical cancer programmes. Methods: Microsimulation model MISCAN used simulate unvaccina...

Background: Human papillomavirus (HPV) is responsible for the development of cervical neoplasia.  Infection with human papillomavirus type 16 (HPV-16) is a major risk factor for the development of cervical cancer. The virus encodes three oncoproteins (E5, E6 and E7), of which, the E7 oncoprotein is the major protein involved in cell immortalization and transformation o...

The potency of human papillomavirus type 16 (HPV16)-encoded synthetic long peptides (SLP), conjugated to an optimized Toll-like receptor 2 ligand (TLR2-L), was assessed in ex vivo activation of HPV16+ cancer patient-derived T cells. Two highly immunogenic SLP sequences derived from the oncogenic E6 protein of HPV16 were selected and conjugated to a Pam3CSK4-based TLR2-L under GMP conditions. Bo...

Invasive cervix cancer (ICC) is the third most common malignant tumor in women and human papillomavirus 16 (HPV16) causes more than 50% of ICC. DNA methylation is a covalent modification predominantly occurring at CpG dinucleotides and increased methylation across the HPV16 genome is strongly associated with ICC development. Next generation (Next Gen) sequencing has been proposed as a novel app...

High-risk human papillomaviruses (HPVs), including type 16, have been identified as factors in cervical carcinogenesis. However, the presence and expression of the virus per se appear to be insufficient for carcinogenesis. Rather, cofactors most likely are necessary in addition to viral gene expression to initiate neoplasia. One candidate cofactor is prolonged exposure to sex hormones. To exami...

This retrospective case-control study assessed human papillomavirus 16 (HPV16) viral load and E2/E6 ratio as risk markers for cervical intraepithelial neoplasia (CIN) ≥2 lesions in HPV16-positive women in a routine liquid-based cytology setting. Triplex quantitative PCR for HPV16 E6, E2, and β-globin was done to determine the HPV16 load and the E2/E6 ratio, as a surrogate marker for integration...
