Filter by:This study will evaluate the performance of Alloderm RTU medium (LifeCell) vs. Cortiva 1mm Allograft Dermis (RTI Surgical®, Inc.). These are the thinnest versions of acellular dermal matrices (ADM) offered by both vendors and can be used for post-mastectomy breast reconstruction. Alloderm RTU medium has a thickness of 1.6±0.4 mm, while Cortiva 1mm Allograft Dermis has a thickness of 1.0±0.2 mm. In the context of breast reconstruction, these ADMs are used in the same manner. They may be inserted with a tissue expander immediately after skin- or nipple-sparing mastectomy. The investigators will examine breast-reconstruction associated complication rates, pre- and post-operative patient reported outcomes using the Breast Q, and physician reimbursement as well as direct hospital costs. The endpoint will be either exchange of the tissue expander for a permanent breast implant or autologous flap, explantation due to patient preference, development of a complication, or less common reasons. The investigators propose that Cortiva 1mm Allograft Dermis and Alloderm RTU will have equivalent complication and patient reported outcome rates as well as physician reimbursement, but that direct hospital cost will be less with Cortiva 1mm Allograft Dermis.
To determine the accuracy of NIR/US assessment of tumor vasculature and oxygen changes in predicting and monitoring early neoadjuvant treatment response compared to pathological response.
To evaluate the effects of homeopathy treatment on radiotherapy-induced fatigue, cognitive and emotional functions.
This is a multicenter, blinded prospective study of 2,000 women undergoing mammography for breast -related symptoms or signs. Breath tests will be performed in order to demonstrate that the outcome of mammography results combined with breast test results improves clinical sensitivity and specificity in a group that has an increased prior probability of cancer. Breath will be collected and analyzed with a rapid point-of-care instrument (BreathLink™) and also with a laboratory-based assay of samples collected into an inflatable bag (BreathBag™).
The overarching goal of the proposed research is to evaluate whether qualitative and quantitative parameters in real time contrast enhanced ultrasound (CEUS) can aid in assessing suspicious indeterminate cystic appearing breast masses and ultimately determine whether or not an ultrasound guided biopsy is necessary. The underlying hypothesis is that breast masses (given BIRADS 4) that lack enhancement on CEUS will have a benign histology obtained by ultrasound guided core biopsy and/or surgery. Then, in the future, these non-enhancing cystic lesions can be followed and do not need biopsy intervention.
The purpose of this study is to determine whether high dose of radiation therapy (RT) are effective over standard 6-week radiation treatment in patients with breast cancer
This study will Investigate whether or not preoperative computed tomography (CT) angiography will lower operative times and post operative complications for breast reconstruction performed with a deep inferior epigastric artery perforator flap (DIEP).
The general purpose of the trial is to investigate whether metformin is taken up into the breast tumor. Studies in the last few years have shown an effect of metformin on cell proliferation on breast cancer. It is though unclear whether the effect on tumor is direct, indirect or a combination of the two. The investigators plan to: - investigate if metformin is taken up in breast cancer using our novel 11C-metformin tracer and positron emission tomography (PET) - investigate whether the uptake is correlated to the amounts of organic cation transporters (OCT1-3, MATE 1 &2 and PMAT) using quantitive polymerase chain reaction (qPCR).
This study investigates the Breathe Well device to test whether it is superior to the existing treatment standard of the Varian Realtime Position Management (RPM) system in assisting patients with deep inspiration breath hold.
The treatment of the patients with recurrent and metastatic breast cancer remains a major problem. There is still a lack of effective targeted therapy for Her-2 negative breast cancer.Based on the present researches on the anti-angiogenesis drugs in advanced breast cancer, the investigators believe that it is necessary to further explore the efficacy and safety of apatinib in advanced breast cancer.
