Filter by:The purpose of this study was to compare the efficacy and safety of Photodynamic therapy (PDT) and Endoscopic submucosal (ESD) dissection in the treatment of early esophageal cancer.
This study evaluates the association of dietary inflammatory potential with breast cancer risk. Information collected in this study may help doctors to identify modifiable risk factors, screen high risk patients early, improve prevention strategies, and provide timely intervention for early therapeutic management as needed.
Cervical cancer is the fourth leading cause of cancer death in women worldwide, and cervical intraepithelial neoplasia (CIN) can progress to cervical cancer. Therefore, timely treatment of CIN is critical in preventing the occurrence of cervical cancer. With the implementation and promotion of the World Health Organization's 2030 Global Strategy for the Elimination of Cervical Cancer, an increasing number of women are detecting and treating CIN at an earlier stage. Common treatment methods include ablation treatment and excision treatment, but for women who are planning to have children, the risk of cervical insufficiency and pregnancy complications is greatly increased after excisional treatment, so ablation treatment seems to be a better choice.
This study is a single-center propsective clinical trial to assess the ability of fluorescence techniques to mark high-grade vulvar intraepithelial neoplasias including high-grade vulvar squamous intraepithelial lesions and differentiated vulvar intraepithelial neoplasias following 3 hours Metvixia application.
This trial studies how well EMBr Wave technology works in reducing hot flashes in women with a history of breast cancer. Hot flashes are a common symptom experienced by menopausal women. The standard treatment for hot flashes is hormone replacement therapy, however hormone replacement therapy cannot be used in women with a history of, or active, breast cancer. EMBr Wave is a personal heating and cooling device worn on the wrist. EMBr Wave may help reduce hot flash severity in women with a history of breast cancer.
This clinical trial aims to find what different tests work best to find high-grade squamous intraepithelial lesions (HSIL) in the cervix or anus in patients living with human immunodeficiency virus (HIV). Patients with HIV are at high risk of becoming infected with human papillomavirus (HPV) in the cervix or anus where it can turn into cancer over several years. HPV causes changes to the cervix and anus, known as HSIL. This means that there is an area of abnormal tissue on the top layers of the cervix or anus. It is considered cervical or anal cancer if the abnormality spreads down into the layers of tissue below the top. If found early, many cases of HSIL can be treated before turning into cancer. Screening for cervical or anal cancer detection or HSIL associated with HPV may result in earlier treatment, if necessary, for patients living with HIV.
HIV-positive patients, women with a history of genital neoplasia and patients under pharmacologically immunosuppression (e.g. transplanted recipients, Crohn´s disease and Lupus) are a high-risk population for anal human-papillomavirus infection and associated complications, like anal precancerous lesions and anal squamous cell carcinoma. There is a lack of information on the prevalence of anal precancerous detected by routine colonoscopy in this population, by evaluating the squamocolumnar junction (the most susceptible area for lesions) during this procedure. Given, the increasing incidence rates of anal squamous cell carcinoma expected for the next two decades and the increase number of at-risk patients, the possible benefit of routine endoscopy in the diagnosis of anal precancerous lesions needs to be further explored.
Introduction Cervical intraepithelial neoplasia CIN1 (low grade), CIN2 (moderate grade), CIN3 (severe grade) defines cervical precancer lesions derived from the squamous epithelial cell line. CIN2, represents a heterogenic phenotype expression of both CIN1-like and CIN3-like evolving lesions with different risk of progression. The CIN2 diagnosis has low reproducibility, and current diagnostic tools do not allow for risk-stratification of CIN2. Risk-profiling is important, to enable targeted management of women with CIN2 at first incidence (surgery or active surveillance) and to avoid risk of over- or undertreatment. Preliminary studies show, that the novel tissue biomarker HPV E4 has potential to discriminate CIN1-like (HPV E4 positive) from CIN3-like (HPV E4 negative) evolving CIN2 lesions, suggesting that the biomarker could be vauable for risk-stratification of CIN2. Aim To examine the potential of the HPV E4 biomarker in predicting risk of CIN2 evolvement. Materials and Methods Design: Historical cohort study. Study population: N=500 women, 23-40 years of age with a record of incidental CIN2 diagnosis between [2000-2010] in the Danish Pathology Data Bank at Aarhus University Hospital, Region of Central Denmark. All women are defined as managed by active surveillance (i.e. no surgical treatment within 4 months after first CIN2 diagnosis). Exposure: HPV E4 positive vs HPV E4 negative intraepithelial reaction. Outcome: Regression (normal, CIN1) vs non-regression (CIN2, CIN3, cervical cancer). Statistical model: Linear regression model (RR (95%CI)). Perspectives: HPV E4 may act as significant predictor for CIN2 evolvement, and reliable marker for risk-assessment of CIN2. This will be valuable in the clinical management of women with CIN2, enabling to discriminate women, who would most likely regress and could be manged by active surveillance vs women in risk of progression or persistence, who could benefit of immediate surgical treatment.
The primary objective of this study is to evaluate the durability of protection and immuno-persistence of Recombinant Human Papillomavirus Bivalent (Types 16,18) Vaccine administered in females aged 18-45 years.
This is a prospective single-institution pilot study examining the feasibility of performing ultrasound-guided cryoablation to completely ablate breast ductal carcinoma in situ (DCIS). The study is designed such that patients meeting selection criteria will undergo cryoablation followed by surgical resection. The pathology of the surgical specimen will be used to determine the rate of complete tumor ablation. Standard adjuvant therapies otherwise remained unchanged.
