New studies suggest that male circumcision can lower the risk of human papillomavirus (HPV) infection, particularly high-risk subtypes associated with cervical, penile, and other cancers. Circumcised men are about half as likely to have HPV as uncircumcised men, according to research published in The Journal of Infectious Diseases.
Arbor Vita Corporation presented new data on its rapid, point-of-care prototype HPV test with a high positive predictive value for cervical cancer and pre-cancer detection. The test detects the E6 oncoprotein produced by human papillomavirus (HPV), which is a diagnostic marker of high positive predictive value.
A comprehensive assessment of HPV-associated cancers found significant racial disparities, with higher rates among African American women and Hispanic men. The study also identified the most common types of HPV-related cancers, including cervical, anal, and oral cancers.
The HPV-positive cancer cells adapted to the hypoxic environment by expressing a protein that activates a cell signaling pathway, helping them survive, grow and spread. The study may lead to new therapies targeting this pathway to interrupt cancer cell proliferation.
Researchers have developed a new MRI technique that can identify cervical cancer in its early stages by measuring the movement of water within tissue. The technique offers better imaging of smaller tumors and may improve surgical options for fertility-sparing procedures.
Only about half of Medicaid recipients aged 50 and older receive recommended cancer screenings for colorectal, breast, and cervical cancer. Despite access to primary care and full coverage, these rates are significantly lower than those in the general population.
A computer model analysis suggests that different cervical cancer prevention approaches offer varying trade-offs between minimizing cancer risk and false-positive test results. Combined cytologic and HPV testing leads to more referrals for colposcopy than other strategies, with a three-fold difference in referrals for the least and mos...

The Phase I/II trial tested Lovaxin C in stage IVb cervical cancer patients, with symptoms including flu-like syndrome, fever, chills, nausea, and vomiting. The study found that five patients experienced tumor reductions or complete disappearance of tumors, while seven patients remained stable, and one patient achieved a partial response.
A new study found that HPV DNA testing can detect clinically relevant cervical lesions earlier than conventional cytological techniques. This allows for the potential extension of the screening interval by at least one year. Earlier detection reduces the lifetime number of screening tests and referrals, benefiting women.
A recent study has found that couples are more likely to divorce if one of their spouses develops cervical or testicular cancer. Most types of cancer resulted in a slight decrease in the divorce rate in the first few years following the diagnosis.
A study found that the -765G>C COX2 polymorphism increases the risk of ovarian cancer by nearly two-fold in C allele carriers and nearly three-fold in women under 53. The mutation may enhance COX-2 gene expression, inhibiting apoptosis and promoting tumour proliferation.
A new study found that irregular Pap smears and false negative tests were not the primary reasons for cervical cancer development. Instead, socio-economic disparities in screening access may be a major obstacle to eradicating the disease.
Researchers found that cervical tumors with high glucose uptake (SUV) on PET scans had higher recurrence rates, persistent disease, and lower survival rates. The study suggests that SUV is a more sensitive indicator of tumor aggressiveness than standard staging protocols.
