Filter by:This is a retrospective cross-sectional study involving the analysis of Cancer Registry Data. As part of this study, cancer registration data collated by the National Cancer Registration and Analysis Service (NCRAS; the national cancer registry in England), via NHS Digital data access request service (DARS), will be analysed on all female patients aged between 25-90+ years in England with a registered diagnosis of anal and vaginal and/or vulvar and/or cervical cancer and/or high grade squamous intraepithelial lesions (HSIL) between 2001 and 2019. For these patients information on age at diagnosis, ethnicity, deprivation, performance status, stage of the cancer at diagnosis, the date of each diagnosis, the treatment received for the diagnosis and the route to diagnosis, will be analysed. Additionally, the total number of women/year (between 1995 and 2019), in England, aged between 25-90+ years with a diagnosis of anal, vulvar, vaginal and cervical cancer as well as their respective HSILs will be requested. Together this data will be used to establish the incidence of anal cancer and HSIL in women with genital cancers and/or HSILs, the progression timelines between the different pathologies, as well as identify relevant sociodemographic risk factors in this patient group.
The primary objective of this study is to determine the magnitude and breadth of the serum antibody response to the nonavalent HPV vaccine (Gardasil-9) in adults with well-controlled HIV infection. The secondary objective of the study is to observe short term clinical outcomes of prevalent HPV genotype-specific anogenital infections in adults living with HIV who complete the three-dose Gardasil-9 vaccine series. The clinical hypothesis is that adults with virologically controlled HIV mount a serum antibody response to the nonavalent HPV vaccine that is comparable to HIV negative counterparts. We also postulate that HPV vaccination will provide short-term clinical benefit against HPV infections and disease associated with vaccine genotypes.
High-grade squamous intraepithelial lesions (HSIL) and anal cancer are rising in incidence and at highest risk are HIV positive men who have sex with men (MSM). This pilot study assessing anal function and patient-reported outcomes before and after laser ablation of HSIL will add to the evidence that such a therapy is an acceptable and safe treatment to offer in a preventative setting.We will be recruting HIV positive and negative MSM.
Human papillomavirus (HPV)-infection belongs to the most common sexually transmitted diseases worldwide. HIV-infected men having sex with men (MSM) are strongly associated with a higher prevalence of genital HPV-infection, a higher incidence of anal intraepithelial neoplasia (AIN), and, consecutively, an increased risk for anal cancer. Since the introduction of highly active antiretroviral therapy (HAART), the incidence of several viral-associated neoplasias has significantly fallen in HIV-infected individuals. At the beginning of the era of HAART, a justified hope existed that genitoanal HPV-related neoplasias would also decrease based on the success of HAART-induced immune restoration. However, HAART seems to have only a small impact on the natural history of AIN as observed in a cohort of HIV-positive MSM before and after the initiation of HAART. As AIN and cancer precursor lesions of the cervix, cervical intraepithelial neoplasia, share distinct clinical similarities, cytologic smear testing for AIN has been recommended to detect and treat early lesions. Thus, this prospective study mainly focuses on the predictive value of HPV-DNA load for the development and clinical progression of AIN in HIV-infected MSM. Moreover, the course of HPV viral load under therapy for anal intraepithelial neoplasia, e.g. topical treatment with imiquimod, will be evaluated. Additionally, immunohistochemical determination of several proliferative biomarkers, as well as cytokines, will be performed.
