(Reuters Health) – Across the world, imprisoned women have higher rates of cervical cancer and the human papillomavirus (HPV) infection that can lead to cancer, according to a research review.
Gynecologic malignancies are among the most prevalent cancers affecting women worldwide, but they are heterogeneous diseases with varying risk factors, management paradigms, and outcomes. Gynecologic cancers mediated by human papillomavirus (HPV) are preventable and curable with early detection and treatment. Dramatic reductions in cervical cancer incidence and mortality have been achieved through cancer screening and HPV vaccination. Radiotherapy plays a central role in the management of gynecologic malignancies. For some cancers, radiotherapy alone can be curative. More often, radiotherapy is used in conjunction with sur…
CONCLUSION: Changing the sexual image of the vaccine could help to establish a collective vaccination policy. Public health policies play an essential role by working with general practitioners and by increasing visibility on the web. The usefulness of the vaccine in 2019 seems to be questioned by Internet users as shown by their major approval of cervical smears. However, these two methods remain complementary in the fight against cervical cancer.

A case-control study was used to explore the association between the methylation status in the promoter regions of the cGAS, MAVS, and TRAF3 genes and the diseases of cervical precancerous lesions (CPL) and cervical cancer (CC) in a Southern Chinese population, and to further explore their interaction effects with high-risk human papillomavirus (hrHPV) infection and environmental factors in these diseases. The study protocol was approved by the ethics committee of The First Affiliated Hospital of Jinan University, and this study was performed in 97 healthy controls, 75 patients with CPL and 33 patients with CC, while each …
Publication date: Available online 12 November 2019Source: Preventive MedicineAuthor(s): Michelle I. Silver, Sarah KobrinAbstractThe human papillomavirus (HPV) vaccine is a powerful tool in cancer prevention. In combination with cervical cancer screening programs, this vaccine has the potential to nearly eliminate death from cervical cancer. However, this remarkable public health success can only be realized if vaccines reach those most at risk—unscreened women. Vaccinating only those already well-screened would have little impact on cervical cancer mortality, exacerbate disparities, and be a striking public health f…
CONTEXT.—: Lower Anogenital Squamous Terminology (LAST) standardization recommended p16INK4a immunohistochemistry (p16 IHC) for biopsies diagnosed morphologically as cervical intraepithelial neoplasia (CIN) grade 2 (CIN2) to classify them as low-grade or high-grade squamous intraepithelial lesions (HSILs).
OBJECTIVE.—: To describe the relationships of p16 IHC and other biomarkers associated with cervical cancer risk with biopsy diagnoses.
DESIGN.—: A statewide, stratified sample of cervical biopsies diagnosed by the community pathologists (CPs), including 1512 CIN2, underwent a…
(Elsevier) A new study in The American Journal of Pathology, published by Elsevier, reports that medroxyprogesterone acetate (MPA), the active ingredient in the common contraceptive injection Depo-Provera, was effective in preventing the development of cervical cancer in mice with precancerous lesions. The drug also decreased existing precancerous lesions. If proven effective clinically, MPA may be a boon to women who do not have access to human papillomavirus (HPV) vaccines.
ConclusionsThe cancer burden attributable to HPV in China is substantial. HPV vaccination and cervical screening should be prioritized.
Cervical dysplastic lesions called cervical intraepithelial neoplasias (CINs) need be treated to prevent cervical cancer. Currently available surgical procedures are effective, but the development of noninvasive treatment is warranted. In human papillomavirus transgenic mice engineered to express human papillomavirus type 16 E6 and E7, short-term treatment with 17 β-estradiol induces CINs that progress to cervical cancer if the treatment is continued. In the present study, this mouse model was used to determine whether medroxyprogesterone acetate (MPA), a progestin drug, is chemopreventive.
High-risk human papillomavirus (HR-HPV) testing is more sensitive than cytology for the detection of cervical cancer and its precursors. However, limited and inconsistent data are available about the efficacy …
