In 2006, cervical cancer was reported as the second most common cancer in women of Malaysia. This type of cancer has been shown to correlate with persistent high risk human papillomavirus (HPV) infection. Although HPV is well known to induce cervical cancer, knowledge of pathways that link the latent stage of the viral replication cycle to precancerous and cancerous stages remains incomplete. However, it is interesting to note that the virus can be isolated from tissues ranging from normal to low-grade squamous intraepithelial lesions as well as high-grade intraepithelial lesions (HSILs), thus prompting scientists to develop HPV detection methods for screening...

Objectives: Recently, three large Chinese cohort studies showed that 7.5% to 15.5% of patients with cervical carcinoma had negative high-risk human papillomavirus (hrHPV) test results on prior cytology specimens. These studies raise the question as to whether these negative hrHPV results represent truly hrHPV-negative carcinomas or false-negative hrHPV test results due to limitations in the testing of cytology specimens. This is increasingly an important question with increasing push to use hrHPV testing alone to screen for cervical cancer...

Cervical cancer is the third highest cause of death in developing countries and most commonly results from high‑risk human papillomavirus (HR‑HPV) infection. Among HR‑HPV genotypes, HPV16 and HPV18 are the most prevalent in cervical cancers. Therefore, the present study aimed to develop a detection assay for HPV16 and HPV18 infection using loop‑mediated isothermal amplification (LAMP) with lateral flow dipstick (LFD) tests. This assay is a simplified, user‑friendly method for the visual detection of HPV genotypes...

Background: The regression discontinuity design (RDD) is a quasi-experimental approach used to avoid confounding bias in the assessment of new policies and interventions. It is applied specifically in situations where individuals are assigned to a policy/intervention based on whether they are above or below a pre-specified cut-off on a continuously measured variable, such as birth date, income or weight. The strength of the design is that, provided individuals do not manipulate the value of this variable, assignment to the policy/intervention is considered as good as random for individuals close to the cut-off...

REVIEW
Sixto M Leal, Margaret L Gulley
Laboratory tests have a key role in preventing human papillomavirus (HPV)-driven carcinomas and in guiding therapeutic interventions. An understanding of the virology, immunology, and carcinogenesis of HPV is essential for choosing appropriate diagnostic test modalities and developing new and even more effective cancer prevention strategies. HPV infects basal epithelial cells on multiple surfaces and induces carcinoma primarily in the cervix and the oropharynx. HPV types are stratified as high risk or low risk based on their carcinogenic potential, driven largely by viral interference with cell cycle regulation and the DNA damage response to promote continuous cell division while thwarting apoptosis, which enables mutation accumulation...

Approximately one-quarter of human papillomavirus (HPV) infections are acquired by adolescents, with a higher burden among racial/ethnic minorities. However, racial/ethnic minorities have been underrepresented in previous HPV vaccine trials. Ongoing and future HPV vaccine optimization trials would benefit from racially- and ethnically-diverse sample of adolescent trial participants. This study examined factors influencing parental willingness to consent to their adolescents' participation in HPV vaccine clinical trials and tested for possible racial differences...

Detecting high-risk-human papillomavirus (HPV) types has become an integral part of the cervical cancer screening programmes. This study aimed to develop a multiplex polymerase chain reaction (PCR) for identification of HPV types 16 and 18 along with the beta globin gene in formalin-fixed and paraffin-embedded cervical biopsy specimens. A total of 59 samples from patients with cervical abnormalities were tested. HPV 16 positivity was 50% in cervical cancers and 52.9% in cervical intraepithelial neoplasia. Our multiplex PCR protocol can be used as a simple and cost-effective tool for high-risk-HPV detection in cervical cancer screening programmes...

CONTEXT: Human papillomavirus (HPV) and Chlamydia trachomatis are the most frequent sexually transmitted infections, usually asymptomatic. Persistent infection with high-risk HPV types and other cofactors such as the concomitant infection with C. trachomatis can represent a higher risk to develop cervical lesions; therefore, screening with sensitive methods could aid to identify women at risk. AIMS: The aim is to determine the prevalence and concurrence of both infections, detected with in-house molecular methods, and to identify the risk factors associated to the infections in Mexican women...

Detection of active human papillomavirus (HPV) is clinically important, as its presence has been shown to correlate with favorable clinical outcomes and better response to treatment in oropharyngeal squamous cell carcinomas (SCC). Using a clinical automated platform, we compared the performance of commercially available HPV DNA and RNA in situ hybridization (ISH) probes in archival tissues of 57 SCC. Importantly, a clinical automated platform gives 1) consistent and reproducible results for HPV ISH and 2) better standardization across clinical laboratories...
