[Amino Acid Substitution Patterns in the E6 and E7 Proteins of HPV Type 16: Phylogeography and Evolution].

The E6 and E7 proteins of the high risk human papillomaviruses (HR HPVs) play a key role in the oncogenesis associated with papillomavirus infection. Data on the variability of these proteins are limited, and the factors affecting their variability are still poorly understood. We analyzed the variability of the currently known sequences of the HPV type 16 (HPV16) E6 and E7 proteins, taking into account their geographic origin and year of sample collection, as well as the direction of their evolution in the major geographic regions of the world.

Accuracy of POC testing systems for HPV screening: the importance of disease prevalence and characteristics of the screened population.

Infectious Agents and Cancer journal has recently launched a new collection of papers about "Point-of-Care (POC) for HPV-related genital cancers" putting together some interesting works on the accuracy of HPV tests for screening. This editorial initiative gave us the opportunity to reflect on the relations between accuracy measures, prevalence and characteristics of the tested population in the case of HPV-based screening. In screening test evaluation, we look at the clinical accuracy of the test as an intrinsic characteristic of the assay, which interacts with the characteristics of the population, the result being the screening performance.

[Human papillomaviruses : origin, oncogenic factors and markers for cervical cancer screening].

The Human papillomaviruses (HPV) have existed in the human population since the archaic hominids. Over the course of human migration and evolution, HPVs have co-evolved with humans on all continents to become today the leading cause of cervical cancer. HPVs are classified by genera, species, genotype, lineage, sub-lineage and variants.

[Vaccination of children and adolescents treated for acute leukemia, excluding HSCT recipients: Recommendations of the French Society for Childhood and Adolescent Cancer and Leukemia (SFCE)].

Children and adolescents who are being treated or have been treated for acute leukemia have a secondary immunodeficiency linked to chemotherapy, resulting in an increased risk of infections. Some of which can be prevented by vaccination but its effectiveness is not optimal during chemotherapy. Upon cessation of chemotherapy, the time required for immune reconstitution varies from three months to more than a year, depending on lymphocyte subpopulations, the patient's age, and the intensity of the treatment received.

Multicenter Evaluation of Morbidity and Predictors of Response to Imiquimod Treatment for Penile Intraepithelial Neoplasia.

Introduction And Objective: Imiquimod (IQ) is an immunomodulator used in the management of penile intraepithelial neoplasia (PeIN) lesions. However, IQ treatment may be associated with bothersome side effects (SEs). To date, studies reporting on this morbidity and evaluating predictors of response to IQ are scarce and included small cohorts.

Effect of External Beam Radiation Therapy and Brachytherapy on Circulating Myeloid-Derived Suppressor Cell Populations in Patients Treated Definitively for Cervical Cancer.

Purpose: The immunosuppressive function of myeloid-derived suppressor cells (MDSCs) has been implicated in the regulation of immune responses against cancer and is associated with poor prognosis. Radiation treatment is known to alter immune cell populations within the tumor; however, whether this results in the recruitment of immunosuppressive MDSC populations is not well understood. Here we evaluate the response of circulating MDSC populations in patients treated per standard-of-care cisplatin chemoradiation therapy (CRT) for locally invasive cervical cancer.

Case report: Multiphenotypic cervical cancer resembling human papillomavirus-related multiphenotypic sinonasal carcinoma.
