Prevaccination Study of Cervical Human Papillomavirus Types in Yangtze River Delta Area, China
Human Papilloma VirusCervical Cancer1 moreHuman papilloma virus (HPV) infection contributes as a main causative factor to the development of invasive cervical cancer (ICC) and its precursors (cervical intraepithelial neoplasia, CIN). Currently, two prophylactic vaccines are employed for the prevention of genital HPV infection. As the prophylactic efficacy is type-restricted, determining the type-specific HPV distribution and their associations with ICC and its precursors would provide essential information in assessment of HPV vaccination program impact. The baseline information is also important for monitoring possible changes in type-specific HPV distribution after vaccination has been introduced. Prevalence of HPV infection varies considerably across the world, and data were limited from less-developed countries. Knowledge of the detail pattern of HPV type-specific distribution in each region will be essential for public health policy decisions. This will also form the basis for determining which types should be included in future generation HPV vaccines targeted to specific regions. While most studies were focus on ICC and high-grade cervical lesions, the association between HPV types and the progression of CIN1 has rarely been studied. CIN1 is an insensitive histopathological sign of HPV infection, most of which will spontaneously regress to normal with host immune system. However, some genotypes have been described as being more persistent and associated with progression from low-grade lesions to high-grade lesions, even ICC. Geographical data on type-specific prevalence of HPV in CIN1 with appropriately designed prospective studies would be helpful in identifying types preferentially associated with progression to malignancy and accurately predicting the future impact of vaccination in specific regions. Free vaccination supported by the government appears to be unlikely at present in China. Thus, individuals need to pay the cost of vaccines for themselves presently. Yangtze River Delta Area is the most economically developed regions in China, and people here may become the largest vaccinated population at their own expense in China. To the best of the investigators knowledge, no multi-center study on HPV type-specific distribution and their associations with ICC and its precursors is available in Yangtze River Delta Area, China, which highlights the need for timely study in this region before large scale vaccination programs are carried out.
Study of Pap Smears From Patients Enrolled on Clinical Trial GOG-171
Cervical CancerPrecancerous ConditionRATIONALE: Studying Pap smears in the laboratory from women with atypical glandular cells of unspecified significance may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is looking at Pap smears from women enrolled on clinical trial GOG-171.
The Association Between Cervical Cancer Screening and Cancer Occurrence
Cervical CancerCancerTo investigate the protective effect of cervical cancer incidence and mortality by screening attending frequency or screening pattern, and to evaluate the possible risk of developing malignancies among women with cervical lesions, inflammation or infection.
Endothelial Progenitor Cells in Cervical Cancer Patients Receiving Chemoradiation
Cervical CancerInvasive carcinoma of the uterine cervix remains the most common invasive cancer in women in many countries. Concurrent chemoradiotherapy (CCRT) is now recommended as a standard treatment for locally advanced and high-risk cervical carcinoma. However, CCRT achieves a better control of cervical cancer accompanied by greater morbidity. To avoid unnecessary over-treatment, the optimization of CCRT is of critical importance. Herein, the development of a surrogate marker for monitoring treatment efficacy as well as toxicity is pivotal to optimize CCRT. Circulating endothelial progenitor cells (EPC), derived from bone marrow, can be used as a marker for optimizing and monitoring the anti-angiogenesis therapy including angiogenesis inhibitors and metronomic chemotherapy. Preclinical models indicated that the source of apoptotic circulating endothelial cells (CEC) was most likely the tumor vasculature. In breast cancer patients, apoptotic CEC were demonstrated to be a surrogate marker for efficacy of metronomic therapy. In this grant, we intent to monitor the levels of circulating EPC/CEC in locally advanced cervical cancer patients before, during and after CCRT.
Hypoxia Imaging With 18F FAZA. Prognostic Impact in Cervical Cancer
Uterine Cervical NeoplasmsThe aim of this study is to visualize the tumor hypoxic tissue, the potential quantitative changes and the biological behavior of cervical carcinoma (primary and / or lymph nodes) before, during and after radiochemotherapy with the novel hypoxia PET tracer 18FAZA.
A New Approach to Cervical Cancer Prevention in Kenya
HealthyThe purpose of this study is to determine if the human papillomavirus (HPV) deoxyribonucleic acid (DNA) testing, performed on self-collected vaginal swabs, is acceptable, feasible, and sensitive and specific in detection of high-grade cervical lesions among Kenyan women, compared to the current standard of care.

Uterine Cervical NeoplasmsSUCCOR study tries to understand the outcomes of European patients with stage IB1 cervical cancer (FIGO 2009)1, that underwent a radical hysterectomy for cervical cancer in 2013-2014 within the ESGO area (European Society of Gynecologic Oncology)
Three-dimensional Study on the Structural Destruction of Pelvic Anatomy in Cervical Cancer
Cervical CancerPostoperative Pelvic Floor DysfunctionCervical cancer is one of the most prevalent malignancies in female .To the younger patients, radical hysterectomy which is a standard operation during the earlier and middle therapy stage as well as more effective technique like radiotherapy and chemotherapy give them a longer life expectancy. However, the operation destroys patients' normal pelvic anatomy, nutrient supplements and internal secretion so that postoperative pelvic floor functional dysfunction has a destructive effect for their life. There are tremendous studies on clinical symptoms while few on anatomical changes and the relationship between pelvic floor symptoms and the dysfunction. Two-dimensional Magnetic Resonance Imaging(MRI), transperineal ultrasonography, Urodynamic examination and anorectal manometry are frequently used in the fine-structure varies and pelvic floor function. Now three-dimensional MRI has more advantages in fine change of Pelvic anatomical and space position,as well as clearly showing the relationships between the change and space with the pelvic floor function. Based on an eight-year-study on three-dimensional MRI, we can analyze the postoperational anatomical changes and the relationship between the changes and the dysfunction by combined anatomic parameters which are measured on static-dynamic three- dimensional model with clinical symptoms, transperineal ultrasonography,urodynamic examination and anorectal manometry. We expect our study could provide scientific basis for on protective and repaired measures of pelvic floor.
