Filter by:Human Papillomavirus (HPV) infection is the most common sexually transmitted infection in the world. It is currently estimated that 4.5% of all cancers worldwide are attributable to HPV, representing 630,000 new cases per year. HPV is responsible for more than 98% of pre-cancerous and cancerous lesions of the cervix and vagina and 88% of anal cancers. Although prevention of HPV infection has been available since 2007, there are approximately 3000 new cases of cervical cancer in France each year. Women benefit from organized screening for cervical cancer. HPV is also responsible for anal cancer in more than 90% of cases, mostly caused by HPV 16/18. Its incidence is lower with 1162 cases in women in 2018 but is increasing strongly (+88% in women since 1990). As with cervical cancer, there are precursors to anal cancer: high-grade intraepithelial lesions. Early diagnosis of these lesions could potentially reduce the incidence of anal cancer, but there are still few data in the literature. The prevalence of anal carriage in patients with a history of cervical dysplasia or cervical cancer is estimated in studies to be 20% with a risk of high grade anal lesions of 8%. The relative risk of developing anal cancer in women with a history of high-grade cervical lesions is about 5 per 100,000, 15 per 100,000 for those with a history of cervical cancer, and 42 and 48 per 100,000 respectively for women with HPV-induced pre-cancer and cancerous lesions of the vulva. The different means of cervico-vaginal screening: screening samples: HPV test, cytology, some biomarkers: double labelling p16/ki67, E6-E7 mRNA and clinical examination with or without colposcopy (examination of the cervix with a magnifying glass) are used at the gynecological level but also at the anal level with as examination: simple anuscopy and high resolution anuscopy. Some scientific societies have established surveillance algorithms for certain risk groups, but there are no clinical practice recommendations yet for women with a history of gynecological HPV-induced lesions. A proctology follow-up protocol for at-risk patients is proposed to patients based on cervico-vaginal surveillance recommendations and data in the literature, pending clinical practice guidelines. The frequency of these examinations depends on the patient's age and the existence of other risk factors for the development of anal HPV lesions. Depending on these elements, follow-up is proposed every 3 years, 5 years, or annually. The objective of this work is therefore to propose proctological surveillance to this population considered at risk, according to age, smear results and HPV test.
There are very little data on human papillomavirus (HPV) vaccination among the 18 million women living with HIV (WLWH) globally, who constitute a population most vulnerable to HPV and the resultant cervical cancer. Particularly, there are no data to date on reduced-dose schedules of nonavalent HPV (9vHPV) vaccination in WLWH and there are very little data on the 9vHPV vaccine in this population overall. It is critical to examine the 9vHPV vaccine in WLWH now because the quadrivalent HPV (4vHPV) vaccine has been discontinued. Additionally, in order to reach the World Health Organization's global goal of cervical cancer elimination, we must determine the role of various HPV prevention strategies in this important population including reduced vaccine dosing which can drastically increase the feasibility of HPV vaccination programs globally. This randomized clinical trial will enrol WLWH aged 18-45 from across Canada who have not previously received an HPV vaccine. Participants will be randomized 1:1 to receive 3 doses of 9vHPV vaccine at the routine vaccine schedule of 0/2/6 months or 2 doses at an expanded schedule of 0/6 months with a third dose at month 12 to adhere to current recommendations for WLWH. We will compare the immune response generated to two versus three doses of 9vHPV vaccine and will follow participants for 2 years to examine the immune response over time. This study, which builds upon our team's prior work on HPV vaccination in WLWH, will determine whether two doses of 9vHPV vaccine can be used in WLWH instead of three, and will examine additional aspects of HPV vaccination in WLWH including the immune response to three doses, vaccine safety and efficacy, and attitudes towards self-collected HPV samples in this population. These data will inform global public health policy and programming and will inform the global strategy for cervical cancer elimination.
The purpose of this study is to find out if lower doses of radiation may help reduce the side effects of radiation therapy in combination with standard-of-care chemotherapy in people with HPV-positive throat cancer. The chemotherapy drugs used in this study include cisplatin, carboplatin, and 5-fluorouracil (5- FU), paclitaxel and abraxane- (Albumin-bound Paclitaxel).
Human papillomavirus (HPV) causes the most prevalent sexually transmitted infections in the world. The nonavalent HPV vaccine (9vHPV) provides protection against 9 high-risk HPV serotypes, responsible for causing approximately 90% of cervical and other HPV-related anogenital cancers, as well as 90% of genital warts. The risk of cancer is substantially increased among immunocompromised patients. Although studies have demonstrated seroprotection among children and adolescents, boys and girls, with the 9vHPV vaccine, the immunogenicity of this vaccine has been poorly explored in immunocompromised children and adolescents (including transplant patients, and those infected with human immunodeficiency virus (HIV)). Several factors, including the immunological consequences of vertically acquired infection, immunosuppressive therapies and age, could lead to an increased risk of infection in children and adolescents who are immunocompromised. Lower immunogenicity in these populations. These children may have a poor response to vaccines and therefore require additional doses. Markers such as CD4/CD8 or torque teno virus (TTV) replication could be linked to immunogenicity and thus serve as predictors of efficacy for routine clinical practice.
The purpose of this study is to validate a new low-cost, self-collected HPV screening test (ScreenFire) and compare it to the standard provider collected careHPV, for the detection of high grade cervical cancer.
This is a retrospective case series study. The Draf III procedure exposes excessive bare bone, resulting in frontal ostium restenosis and surgical failure. For tumors originating from frontal sinus, especially inverted papillomas, abrading of bone around frontal ostium often exacerbate the restenosis. This study aims to retrospectly recruit patients with frontal sinus inverted papillomas who received Draf III procedure in our center during 2015-2021 and investigated the efficacy of a novel pedicled nasoseptal flap for endoscopic frontal sinus procedures. Each subject received a CT and magnetic resonance imaging (MRI) scans before operation. The subjects were followed up postoperative for at least 12 months to check the epithelization status and whether the neo-ostium were patent.
A study on two different methods of invitation to participate to the cervical cancer screening programme will be conducted within a demonstration project to switch from cytology-based screening to HPV-based screening using self-sampling delivered through the network of pharmacy offices among regular screening attendants in the Barcelona Metropolitana Sud Area, in Catalonia. At the moment, eligible women are invited to participate to cervical cancer screening via a telephone call invitation explaining the new self-sampling method. Invitation via SMS containing a link to a webpage with information on most frequent questions might be an adequate alternative method that would save costs and workload on human resources. The aim of this study is to assess the impact on cervical cancer screening participation of an invitation method based on text messaging (SMS). The invitation method will be evaluated through an interventional trial, in which we will compare the invitation to cervical cancer screening using SMS versus a telephone call invitation explaining the new self-sampling method.
This study is an open-label nonrandomized exploratory proof of concept and descriptive 4-year immunogenicity study to assess immunogenicity after administration of a 2-dose regimen of 9-valent human papillomavirus vaccine (9vHPV) vaccine separated by 12 months (months 0, 12).
This study will look at whether monitoring HPV ctDNA levels is an effective way to detect cancer relapse risk in people with HPV-OPC. All participants will have recently had surgery to treat their disease, or they will be scheduled to have this surgery. In Arm A the researchers will see whether monitoring participants' HPV ctDNA levels can safely identify patients who do not need radiation therapy (RT) after surgery and whose RT can be delayed until their HPV ctDNA levels become detectable. In Arm B, the researchers will see whether patients who usually need 6-6.5 weeks of CRT can be selected by HPV ctDNA to receive 3 weeks of CRT.
