Filter by:Participants undergoing radiation after breast conserving surgery for an early breast cancer (either Ductal Carcinoma In Situ (DCIS), or Early Stage Invasive breast cancer), and are at increased risk of developing a skin reaction because of their large breast size. After breast conserving surgery (also known as a 'lumpectomy'), women with either DCIS or early stage invasive breast cancer receive radiation to the breast to decrease the risk of cancer recurrence. Breast radiation is usually done with women lying on their back ("supine"). Some women develop temporary breakdown of the skin (moist desquamation). This skin reaction can be painful and has been linked to long term side effects such as chronic pain and decreased quality of life. This study is being done because women with large breasts have higher rates of skin breakdown (called 'moist desquamation') and breast pain during and shortly after radiation therapy is complete. It is unclear if such skin reactions and pain would be improved by alternating treatment position - namely lying on your belly ("prone") during their radiation treatment.
This pilot clinical trial studies magnetic resonance thermal image guided laser interstitial thermal therapy in treating patients with breast cancer. Magnetic resonance thermal image guided laser interstitial thermal therapy may be able to kill tumor cells by heating up the tumor cells without affecting the surrounding tissue
Optical Coherence Tomography (OCT) is a technology using harmless near infra-red light scatter to produce an image. Prior studies with OCT have demonstrated that OCT of the uterine cervix can differentiate between grades of pre-invasive and invasive cervical disease and cancer. This study will evaluate the ability of the NIRIS 1300e imaging (OCT) system to detect pre-invasive cervical disease and cervical cancer.
This phase II trial studies how well radiation therapy works in treating post-menopausal women with early stage breast cancer undergoing surgery. Radiation therapy uses high energy x rays to kill tumor cells. This may be an effective treatment for breast cancer.
This randomized pilot trial studies broccoli sprout extract in treating patients with breast cancer. Broccoli sprout extract contains ingredients that may prevent or slow the growth of certain cancers. Studying samples of tissue from patients receiving broccoli sprout extract may help determine if it can enter breast tumor cells and how it affects certain biomarkers.
This is a Phase III clinical trial of the novel recombinant HPV 16/18 bivalent vaccine manufactured by Xiamen Innovax Biotech CO., LTD. The primary objective of this study is to demonstrate the efficacy of the vaccine against relevant outcomes in healthy women above 18 years old at enrolment. The secondary objectives are to evaluate the safety, immunogenicity and immuno-persistence of the vaccine. Meanwhile, this study tries to compare the difference of safety and immunogenicity among different lots. Approximately 6000 study subjects will be enrolled and randomly stratified into 2 groups and receive human papillomavirus (HPV) vaccine(three different lots) or commercialized hepatitis E vaccine(Hecolin) according to a 0-1-6 month schedule.
LAY SUMMARY A type of gullet cancer (oesophageal adenocarcinoma) has become the 5th commonest UK cause of cancer death. Unfortunately, by the time patients have symptoms, the cancer is often incurable. People with Barrett's oesophagus (change of gullet lining occurring in some with acid reflux) at risk of this cancer can have regular check-ups, involving examination through an endoscope (an instrument inserted by mouth, under mild sedation if required). A small proportion of people with Barrett's develop further changes (which might become cancer) in the gullet lining; if they do, it is important to remove the affected tissue before cancer develops, or when it is at an early stage. There are several ways of removing this tissue but the investigators do not know which is best. The standard treatment is surgery, but there is a small risk of dying from the operation, and patients often suffer complications affecting them for a year or more afterwards. Two endoscopic treatments do not involve surgery. Both involve removing visible abnormalities by a technique called endoscopic resection, followed by cauterising the remaining Barrett's gullet lining by 1 of 2 techniques. One is recommended by the National Institute for Health and Clinical Excellence, but it is expensive and less widely available than the second. No-one has compared these treatments with each other, nor with surgery, in randomised trials (the most reliable way of deciding which is best). Patient groups say they would prefer to avoid surgery if the alternative works, and have encouraged us to do trials. This feasibility study is a vital step towards two trials: (a) a trial to compare the two non-surgical techniques and (b) a trial comparing surgery with endoscopic treatment. It will help us find out whether it will be possible to enroll and retain enough patients by using several centres, and to identify/resolve any other potential barriers to recruitment and retention, including exploring viewpoints of patients and surgeons.
This is a Phase II pilot study to explore the effect of intravesical TMX-101 in patients with CIS bladder cancer, as assessed by histology and cytology after TMX-101 treatment.
Many hospitals, including the Ohio State University Medical Center, will take pictures of the blood vessels in a patient's abdomen before they decide to perform a breast reconstruction using the patient's own tissue. These pictures are called computed tomography (CT) angiograms and are like a map of each patient's anatomy. However, no study has been reported that determined how accurate these pictures are at showing the surgeon where all of the blood vessels were located. This study will try to determine if these pictures are missing any blood vessels that are found during surgery and if the pictures show the correct location of the vessels
To compare the efficacy of cryotherapy and large loop excision of the transformation zone (LLETZ) procedures for the treatment of high-grade cervical intra-epithelial neoplasia (CIN2/3) among HIV-seropositive women by follow-up VIA, cytology and Human Papillomavirus. Hypothesis: LEEP will be more effective than cryotherapy in removing CIN 2/3 lesions in HIV positive women in South Africa
