Filter by:Evaluation of the 3-years anal carcinoma (AC) incidence in patient with anal AIN3 lesions, and factors associated with this AC. A retrospective cohort study will be conducted (2000-2013) followed by a prospective cohort study (starting in 2013) with new diagnoses of anal AIN3 lesion. The main outcome is histology proven AC. The 3-years incidence rate of AC will be calculated. Factors associated with AC will be estimated using a multivariate Cox regression model.
This randomized clinical trial studies a group-based lifestyle intervention or usual care in measuring biomarker levels in participants at high risk for breast cancer. Studying the effects that changes to daily eating and exercise habits can have on the body's hormone levels and the body's ability to activate proteins may help doctors identify interventions for individuals at high risk for breast cancer.
Conventional techniques of endoscopic mucosal resection (EMR) by snare resection do usually not achieve resection of gastrointestinal mucosal neoplastic lesions larger than 1 cm in diameter in a single piece. Complete R0 resection cannot be histologically confirmed. In contrast to EMR the technique of endoscopic submucosal dissection (ESD) allows en-bloc resection even of large neoplastic lesions. The waterjet-assisted ESD technology (WESD) allows pressure controlled injection of fluids through the tip of a recently developed HybridKnife®. Submucosal injection, circumferential cutting and dissection of lesions as well as coagulation of bleeding sources can be performed with the same device without need for changing the instrument. Our group reported on effective en-bloc resection of esophageal areas in all of 14 cases of an Erlangen porcine model. We subsequently compared WESD with EMR of predefined esophageal mucosal lesions in anesthetizised pigs in a randomized controlled trial. The results demonstrated that WESD more frequently achieved a complete resection with a significantly lower number of specimen. WESD caused no perforations and bleedings could be endoscopically managed during the procedure. In addition we recently reported on this technology in a first clinical trial on WESD for early Barrett`s neoplasia . The results indicated that WESD can be safely and effectively performed in the esophagus. Therefore the primary objective of this study is to compare the R0 resection rate of ESD and EMR for visible lesions of HIgh grade intraepithelial neoplasia (HGIN) or esophageal adenocarcinoma (EAC). Secondary objectives are related to completeness of resection, safety of the procedures, the medium term outcome and comparison of costs.
This phase II clinical trial studies how well omega-3 fatty acid works in treating patients with stage I-III breast cancer. Studying samples of tissue and blood in the laboratory from breast cancer patients receiving omega-3 fatty acid may help doctors learn more about the effects of omega-3 fatty acid on tumor cells.
To evaluate the efficacy (defined as complete clinical response at 6 months) of imiquimod vs. standard treatment (surgery) for vulvar intraepithelial neoplasia (VIN).
This randomized phase II trial studies how well docosahexaenoic acid works in preventing recurrence in breast cancer survivors. Docosahexaenoic acid supplement may prevent recurrence in breast cancer survivors.
The rate of axillary dissection avoided in patients with Ductal Carcinoma in Situ (DCIS) and a mastectomy indication will be obtained by calculating the proportion of women with GAS in-patient population that will prove to be DCIS or DCIS-MI + CCI. A confidence interval of 95% will be deferred.
MUCIPLIQ is a nanopolymer engineered to mimic glycosaminoglycans such as heparan sulfates. Glycosaminoglycans are involved 1) in the stabilization of cells micro-environment, known as extracellular matrix, by binding to structural proteins, and 2) in cells communication process by protecting growth factors. At the site of a lesion, glycosaminoglycans are degraded, thereby the extracellular matrix is disorganized and the tissue is destroyed. By replacing damaged glycosaminoglycans, MUCIPLIQ provides a protection, and restores the matrix scaffold and cells communication, a process known as Matrix Therapy. The purpose of this new controlled study is to determine whether MUCIPLIQ can decrease the incidence and the severity of radio-chemotherapy-induced mucositis in patients suffering of upper aerodigestive tract cancers, when used as a preventive agent. The study's main hypothesis is that MUCIPLIQ mouthwash applications before radiotherapy would protect the healthy oral tissue against cytotoxic effect of chemotherapy and radiations.
The purpose of this study is to determine the efficacy and the safety of PGA(Poly-gamma Glutamic Acid) for the the fertile women with Cervical Intraepithelial Neoplasia (CIN1).
This pilot clinical trial studies caloric restriction in patients with stage 0-I breast cancer during surgery and radiation therapy. Reducing caloric intake may prevent disease progression in patients with breast cancer. Radiation therapy uses high energy x rays to kill tumor cells. Giving dietary intervention and radiation therapy together may kill more tumor cells.
