The incorporation of multiple antigens into a single human papillomavirus (HPV) vaccine may induce immune interference. To evaluate whether interference occurs when HPV type 16 (HPV16) virus-like particles are combined in a multivalent vaccine, we conducted a study to evaluate anti-HPV16 responses among subjects receiving three-dose regimens of either a monovalent HPV16 vaccine or a quadrivalent HPV (types 6, 11, 16, and 18) vaccine.

HPV status is an important prognostic factor in oropharyngeal squamous cell carcinoma (OPSCC), with HPV-positive tumors associated with better overall survival. To determine HPV status, we rely on the immunohistochemical investigation for expression of the P16 protein, which must be associated with molecular investigation for the presence of viral DNA. We aim to define a criterion based on image analysis and machine learning to predict HPV status from hematoxylin/eosin stain.

Background And Purpose: The similarities in biology, treatment regimens and outcome between the different human papillomavirus (HPV) associated squamous cell carcinomas (SCCs) allow for extrapolation of results generated from one SC tumor type to another. In HPV associated cancers, HPV is integrated into the tumor genome and can consequently be detected in the circulating fragments of the tumor DNA. Thus, measurement of HPV in the plasma is a surrogate for circulating tumor DNA (ctDNA) and holds promise as a clinically relevant biomarker in HPV associated cancers.

The coronavirus disease 2019 pandemic substantially impacted the delivery of cancer services and programs. Here we reviewed and synthesized the global scale and impact of pandemic-related delays and disruptions on cancer services, including diagnosis, diagnostic procedures, screening, treatment and supportive and palliative care. Based on data from 245 articles in 46 countries, we observed declines in the number of cancer screening participation (39.

Unlabelled: Human papillomavirus (HPV) genotype predicts cervical cancer risk, and genotyping could help guide the management of HPV positives as part of cervical screening. An isothermal amplification HPV extended genotyping test (ScreenFire HPV RS assay) can assay up to 96 samples/controls in 1 hour plus preparation time. A novel format with pre-aliquoted reagents and an anti-contamination component (Zebra BioDome) could simplify the HPV testing process and reduce the chances of post-amplification contamination.

Introduction: Diagnostic work-up of older women with a positive cervical cancer screening test is often challenging due to incomplete visualization of the transformation zone. To reduce the risk of missing disease, a diagnostic cervical excision may be performed. However, little is known on treatment efficacy and post-treatment surveillance for older women.
