Wednesday, November 15, 2017 -- Researchers have found that human papillomavirus (HPV) vaccine may also protect against recurrent respiratory papillomatosis, a rare, but incurable childhood respiratory disease.
Friday, November 17, 2017 -- Like cervical cancer, anal cancer and its direct precursor lesion, high-grade anal intraepithelial neoplasia (AIN), are caused by persistent infections with human papillomaviruses (HPV).1 The natural history of HPV in cervical cancer has been comprehensively investigated. In the more than 40 HPV types infecting the anogenital tract, high-risk HPV-types and possible or probable high-risk types for the development of cervical cancer have been defined.2 Cervical cancer is preventable by regular screening.
Wednesday, November 15, 2017 -- BACKGROUND AND PURPOSE: Head and neck squamous cell carcinoma associated with human papillomavirus infection represents a distinct tumor entity. We hypothesized that diffusion phenotypes based on the histogram analysis of ADC values reflect distinct degrees of tumor heterogeneity in human papillomavirus–positive and human papillomavirus–negative head and neck squamous cell carcinomas. MATERIALS AND METHODS: One hundred five consecutive patients (mean age, 64 years; range, 45–87 years) with primary oropharyngeal (n = 52) and oral cavity (n = 53) head and neck squamous cell carcinoma underwent MR imaging with anatomic and diffusion-weighted sequences (b = 0, b = 1000 s/mm2, monoexponential ADC calculation). The collected tumor voxels from the contoured ROIs provided histograms from which position, dispersion, and form parameters were
Friday, November 17, 2017 -- HPV16 is by far the most carcinogenic HPV type in the anus, with enrichment of HPV16 even from high-grade lesions to anal cancer, both in individuals who are HIV negative and those who are HIV positive. Nevertheless, the fraction of anal cancer attributable to HPV16 is smaller in the HIV-positive population.
Monday, November 20, 2017 -- There are about 20 000 new cases of anal cancer per year globally, of which an estimated 90% are caused by human papillomavirus (HPV) infection. New research by scientists from the International Agency for Research on Cancer (IARC), published today in The Lancet Infectious Diseases, characterizes the contribution of different oncogenic HPV types to the development of anal cancer, in HIV-negative men and women as well as in high-risk HIV-positive populations.
