Filter by:This proposed study will examine feasibility and implement therapeutic bright light that is tailored to the individual's circadian typology to estimate its therapeutic effects on sleep/wake patterns and fatigue in breast cancer patients undergoing chemotherapy.
To examine whether rapamycin can reduce malignant markers and aberrant mammary stem/progenitor cells (MaSCs) number in surgical specimens
Fear of cancer recurrence (FCR) is one of the most prevalent, persistent, and disruptive sources of distress for adult cancer survivors. Prevalence rates for FCR have been estimated at up to 89%, with approximately half of cancer survivors reporting clinically significant levels of FCR. Despite the recognized prevalence, persistence, and suffering associated with FCR, effective and accessible treatments for FCR are lacking and urgently needed. Our long-term goal is to develop, evaluate, and implement effective behavioral interventions for cancer survivors suffering with FCR.
Multiple neoadjuvant endocrine trials demonstrate that women with good prognosis tumors can be identified. These trials have also demonstrated that there are not adverse effects on overall outcome if women are treated with neoadjuvant endocrine therapy for several months prior to definitive treatment. A new standard of care needs to be defined for elderly women with good prognosis estrogen receptor (ER)+ tumors, since these women may benefit from endocrine therapy alone to treat their cancer without compromising local and distant control. The investigators hypothesize that endocrine therapy alone provides adequate local and systemic control of breast cancer in a subpopulation of women 70 or older with ER+ breast cancer and low Ki67 scores.
The investigators propose a randomized controlled superiority trial of standard breast-conserving surgery (BCS) versus BCS with cavity shave margins (CSM). The main objectives of this trial will be to evaluate prospectively the impact of routine standardized CSM on margin status following primary surgery for early stage breast cancer (Stage 0 - II), on post-operative patient satisfaction and cosmetic outcomes, and on general intraoperative time and operative costs. A parallel group format will be implemented to compare this modified surgical therapy - BCS with CSM - with BCS alone, which is the current standard of care.
Selected patients with early stage breast cancer undergone conservative surgery were randomized in two arms: Hypofractionated Whole Breast Irradiation versus Accelerated Partial Breast Irradiation.
The NIR light source of our device is based on light-emitting diodes (LEDs), which can deliver sufficient light to biological tissues and induce fluorescence emission to meet the needs of the planned clinical studies. It should be noted that the light source is still well under the US FDA recommended limit for NIR exposure and ANSI standard. In addition, the light source is not laser-based, which is significantly safer than other optical imaging systems utilizing laser technologies. The fluorescence signals will be received by the detector portion of our device. Gain-settings could be easily adjusted during operation to optimize the contrast between high fluorescence areas (tumors) and low fluorescence areas (normal tissues). Real-time fluorescence video will be displayed in the goggle eyepiece as well as on a secondary monitor to facilitate viewing by other surgeons in the room.
This study is designed as an open-label randomized parallel two-arm multicenter efficacy, pharmacokinetics and safety study of intravenously administered eribulin versus intravenously administered vinorelbine in Chinese population. Eligible female subjects will have measurable disease according to RECIST 1.1 with the modification that chest x-ray cannot be used for assessment of disease.
The purpose of this study is to determine the effects of combining metformin and atorvastatin treatment in patients with newly diagnosed breast cancer during the interval between breast biopsy and surgery. This study is designed to assess whether tumor proliferation, as measured by the natural log expression of Ki-67 staining of breast tumor cells, is reduced following approximately 2 weeks of treatment with the combination of metformin plus atorvastatin in patients with newly diagnosed breast cancer.
The goal of this study is to compare two different types of breast surgery. In the first type, the doctor removes only the tumor. In the second type, the doctor removes the tumor and some of the tissue around the tumor called margins. The amount of breast tissue removed is similar. The removal of the tumor only has up to 40% chance of reoperation because the tumor is too close to the margin. The primary goal of this study is to see if the additional margins can decrease the need to return to the operating room. Both types of surgery are well accepted, and participating in the study would not give you a better chance to cure the cancer. At present, most breast surgeons remove the tumor without the additional margins. For all patients who have this operation, there is a high incidence of return to the operating room for margins re-excision: as many as 40% as patients can have a re-operation. At present, we do not know if taking the additional margins prevents the cancer from returning in the breast or not. If the cancer comes back in your breast, this is a recurrence and your breast will have to be removed (mastectomy).
