Filter by:The study hypothesis is that the rate of inadequate surgical margins after conservative breast surgery for DICS and the rate of reoperation (re-excision or/and mastectomy) is lower in the group of patients who underwent standard preoperative mammography and CEM to assess the extent of DICS, compared to the group of patients for whom the preoperative assessment of the extent of in situ breast cancer was not performed using one of the imaging techniques with contrast medium such as contrast mammography or magnetic resonance imaging.
This is a phase II double blind, placebo-controlled, randomized study of artesunate ointment for the treatment of HIV-negative men and women who have anal high grade squamous intraepithelial lesions (anal HSIL)
This phase II trial evaluates tamoxifen, with or without omega-3 fatty acids, for reducing risk of breast cancer among postmenopausal and overweight or obese women who are at increased risk of developing breast cancer. Tamoxifen is a selective estrogen receptor modulator. It works by blocking the effects of the hormone estrogen in the breast. Tamoxifen is approved by the Food and Drug Administration for prevention of breast cancer in women at increased risk. Omega-3 fatty acids have been shown to decrease the amount of fats made in the liver. Omega-3 fatty acids may work to prevent cancer in overweight or obese individuals. Tamoxifen with or without omega-3 fatty acids may be effective at reducing risk of breast cancer among women who are postmenopausal, overweight or obese, and at increased risk.
Normally, p53 helps prevent tumors from forming in the body. Early studies have shown that Fenofibrate, a cholesterol-lowering drug, can restore normal function to p53 and can change the metabolism of HPV-positive tumors in a way that stops the growth of tumors. The purpose of this study is to understand how Fenofibrate can be used to treat HPV-positive cervical cancers and cervical dysplasia. Researchers will examine collected tissue samples and investigate various genes and proteins to see whether Fenofibrate has an effect on HPV-positive cervical cancers and cervical dysplasia.
This phase II trial evaluates response-guided low-dose tamoxifen for reducing breast density in women who are at higher than average risk for breast cancer. Increasing breast density is a well established risk factor for breast cancer. Tamoxifen is a selective estrogen receptor modulator. It works by blocking the effects of the hormone estrogen in the breast. Tamoxifen has been shown to reduce breast density, even at reduced dosages, and is approved for the prevention of breast cancer.
A database has been created and will be used in which data will be collected in electronic format relating to adult patients who underwent one of the following endoscopic resection surgeries: TURBK, MAPPING, TURBK SECOND LOOK, BLADDER BIOPSIES.
The goal of this clinical trial is to test how safe and effective it is to treat early form of cancer cells found in the upper skin layer of the face, using a light-sensitive cream used in combination with a light source. The main questions this trial aims to answer are: - to confirm using laboratory testing, how much of the affected facial skin cancer section the treatment was able to remove, and; - seeing how many participants had no remaining affected facial skin cancer sections after treatment. Participants who qualify will be asked to complete 12 visits in total and will receive a total of two treatments, after voluntarily consent has been given.
To determine the number of MBC cases as well as the demographics, characteristics, and outcomes of MBC patients at Methodist Health System (MHS).
The goal of this retrospective multicenter observational study is to understand and evaluate the diagnostic and therapeutic management of pure forms of Florid Lobular Carcinoma In Situ (FLCIS) and Pleomorphic Lobular Carcinoma In Situ (PLCIS) of the breast. It addresses the significant challenges and controversies surrounding their clinical management, due to a lack of consensus or approved international guidelines. The main questions this study aims to answer are: - How is the diagnostic process for pure FLCIS and PLCIS currently managed? - What are the primary therapeutic approaches for these specific breast conditions? - How are positive and "close" surgical excision margins handled? - Is adjuvant treatment, such as hormone therapy and radiotherapy, necessary? - What factors are associated with recurrences? - What are the rates of recurrences and/or upgrade to invasive carcinoma? Participants will retrospectively collect all cases of pure FLCIS and PLCIS, reporting detailed data about their diagnostic and therapeutic management, as well as clinical and survival outcomes. Methodology: This international multicenter retrospective study will collect cases involving the pure forms of FLCIS and PLCIS of the breast. The study aims to provide insights into the current diagnostic and therapeutic approaches, along with the identification of opportunities to enhance clinical management, ultimately providing evidence-based recommendations and addressing the current lack of scientific literature regarding their treatment.
The purpose of this research study is to evaluate the outcomes of two standard of care group exercise regimens to increase muscle mass in women who have been treated with breast cancer.
