Filter by:The American Society for Colposcopy and Cervical Pathology (ASCCP) recommended HPV testing or co-cytology testing as the standard primary approach for cervical cancer (CC) screening, which is highly sensitive for detection of cervical intraepithelial neoplasia grade 3 or worse. However, in clinical CC screening practice, the specificity and positive predictive value of the ASCCP-recommended strategy is relatively low, which leads to excessive colposcopy and common overtreatment, especially in China with a large number of cervical cancer cases. HPV integration in the host genome is a critical step in cervical carcinogenesis and is highly specific for detection of cervical cancer. Whether HPV integration analysis can play a role in the triage of cervical cancer screening has not yet been investigated.
Human papillomaviruses (HPV) are the most common sexually transmitted pathogens worldwide and in most cases are causally associated with the development of cervical cancer, one of the most common cancers in women and one of the leading causes of death in women worldwide. Precancerous lesions (dysplasias) or the presence of a high-risk HPV subtype are detected by a screening smear test performed by a gynecologist. If precancerous lesions are detected, conization (= surgical removal of a cone of tissue from the cervix) is the method of choice for removing the diseased tissue. However, if the degree of dysplasia is correspondingly low or the smear is unclear, then the guideline-compliant non-surgical treatment provides for a wait-and-see approach with PAP and HPV smear control after 6-8 months. This "wait-and-see" approach can be complemented by local therapy with an immunostimulant. For this purpose, DEFLAGYN® (a vaginal gel containing silica and citric acid) and Aldara® (imiquimod, a Toll-Like Re-ceptor 7 antagonist) are available. However, while the latter is not approved for the treatment of cervical dysplasia or HPV infection, DEFLAGYN® has CE marking and approval as a medical device for treatment in a number of indications, such as unclear cervical smears, HPV-induced cervical lesions, p16/Ki-67-positive cervical lesions or cervical erosions. However, available studies on the efficacy of DEFLAGYN are limited. For example, there is only one prospective randomized trial (Major et al, 2021, Arch. Gynecol. Obstet. 303:501-511), which included 216 women with histologically confirmed CIN 1/2. A 3-month intravaginal application of DEFLAGYN® resulted in regression of CIN 1/2 in 72% versus 25% in the control arm (no intervention). Side effects of therapy with DEFLAGYN® were not observed in this study. Due to the frequency of CIN and HPV infections in the female population and due to the high medical relevance of a conservative method of treating this disease, further methodologically high-quality studies on the efficacy of DEFLAGYN® should be performed.
Poor quality of primary care providers' vaccine recommendations lead to low adolescent human papillomavirus vaccination rates and hundreds of thousands of adolescents unnecessarily at risk for HPV-associated cancers and diseases. Though a previous provider communication intervention, called PCOM, was found to be effective for increasing adolescent HPV vaccination in primary care, its dissemination is limited by the need for significant research team involvement to teach providers how to use the intervention's components. To address this, investigators propose to develop and test a virtual version of PCOM, use mixed methods to assess contextual factors affecting its use compared to the original PCOM intervention, and develop an optimized version of PCOM for broad dissemination to increase adolescent HPV vaccination nationally.
Solid organ transplant recipients (OTRs) receive lifelong immunosuppressive therapy, which puts them at increased risk of cutaneous and mucosal cancers. In particular, OTRs have increased risk of skin cancer and cancers caused by human papillomavirus (HPV), including cervical cancer and oropharyngeal cancer. There is currently limited knowledge on risk factors for HPV infection and skin cancer in OTRs, and limited knowledge on the natural history of HPV infection and cervical neoplasia in OTRs compared with immunocompetent controls. With a continuously increasing number of OTRs, there is a growing need to improve our understanding of the long-term reactions to immunosuppression. The overall aim of this study is to investigate long term effects of immunosuppression on cutaneous and mucosal epithelium in Danish OTRs, including the risk of skin dysplasia and skin cancer, cervical and oral HPV infection and HPV-related dysplasia and cancer in OTRs. This study will be designed as a prospective observational cohort study based on clinical data and data from nationwide Danish registries. A total of 600 female OTRs, 600 male OTRs and 600 female controls will be included from Danish dermatology departments. The study aims to provide knowledge relevant for improving prevention of skin- and HPV-related cancers in OTRs, including personalized screening recommendations according to individual patient risk.
Clinically, patients with persistent HR-HPV infection for more than 18 months or HR-HPV infection with CIN2 + need regular colposcopic biopsy to assess the outcome and progression of the disease. A total of 1000 participants with persistent HR-HPV infection (100 cases/center) were recruited from multiple centers, and HPV integration status and vaginal flora diversity were sequenced at baseline, 6th month, 12th month and 24th month, respectively, through prospective cohort studies. And to evaluate the influence of HPV integration status and flora changes on the prognosis of women with persistent HR-HPV infection.
Human papillomavirus (HPV) infection has become one of the most important health problems faced by women all over the world. A large number of studies have shown that women's cervical, vaginal and perianal precancerous lesions, related cancers, condyloma acuminatum and other sexually transmitted diseases (STD) are closely related to HPV infection. Among them, the persistent infection of high-risk human papillomavirus (HR-HPV) is closely related to the occurrence of invasive cervical cancer. Previous studies have shown that there are significant differences in the effects of multiple HPV infection and persistent infection of different types (such as type-16, -18, -39 and -52) on different levels of cervical lesions, and there is a certain correlation between HPV load in the process of persistent infection and the degree of cervical lesions. In addition, other studies have shown that HPV-16 viral load has certain clinical significance in predicting Cin2 / CIN3 high-grade cervical lesions, and HPV viral load level is significantly different in cervical low-grade squamous intraepithelial lesion (LSIL) and cervical high-grade squamous intraepithelial lesion (HSIL). The above biological changes such as HPV infection type, quantity and proportion can promote the occurrence and development of cervical precancerous lesions and related cancers to varying degrees. It can be seen that the study of the relationship between HPV viral load and cervical lesions is of great significance for clinical disease development prediction and cervical cancer screening.
Clinically, cervical precancerous lesion is one of the important diseases that endanger the life safety and fertility of young women. Women with histopathologically confirmed CIN2 need regular HPV, cervical cytology, and colposcopic biopsy if necessary to assess the outcome and progression of the disease. In this study, we intend to visit Fujian Maternal and Child Health Hospital, Tongji Hospital affiliated to Tongji Medical College of Huazhong University of Science & Technology and other hospitals, including 300 CIN2 participants aged 45 and below diagnosed by histopathology, and collect the remaining cervical secretions and cervical exfoliated cell samples after clinical examination, even if you do not participate in this clinical study. In clinical diagnosis, treatment and follow-up, it is also necessary to collect the above specimens for relevant medical tests. Therefore, it is of great clinical and scientific significance to explore the role of HPV integrated detection in predicting the prognosis of young women with CIN2.
A total of 13500 Chinese women aged 18-45 years old were divided into three age groups: 18-26 years old, 27-35 years old, and 35-45 years old. The experimental group and the placebo group were randomly assigned in a ratio of 1:1. All subjects enrolled in the upper arm deltoid muscle were injected with 3 doses of test vaccine or placebo according to the 0, 2, and 6 months immunization program.
