Breast cancer is a multifactorial disease affecting women, and one of the treatments for its healing and survival is hormone therapy. Aromatase inhibitors are third-generation drugs that promote lower chance of metastasis, but their side effects include the loss of bone mineral density and increased fat percentage. In this way, the Combined Training (combined resistance and endurance training) may be an interesting strategy to minimize the side effects of aromatase inhibitors, providing better quality of life, survival and changes in body composition.
The purpose of this randomized intervention study is to test the efficacy of the technology-based information and coaching/support program for Asian American breast cancer survivors (TICAA) in enhancing the women's breast cancer survivorship experience.
VENTANA is a "window-of-opportunity" trial that will explore whether, similar to CDK4/6 inhibitors, Oral Metronomic Vinorelbine in combination with Letrozole induces a superior anti-proliferative effect than Letrozole alone.
Magnetic resonance imaging (MRI) is the method of choice in breast cancer to perform the loco-regional staging and direct the treatment. European Guidelines (EUSOMA) currently recommend MRI for initial evaluation and assessement of the neoadjuvant chemotherapy (NAC) response, for breast cancer. The standard of care consists of realizing a MRI before the start of the NAC and another one after it's ended, six months later. There is currently no consensus on the realization of an interval MRI for early assessment of the chemosensitivity of the tumor. It would allow though alterations in the therapeutic regimen in the event of a non response. Similarly, there is no consensus on when this interval MRI should be performed. Some recent studies suggest that Diffusion-weighted Magnetic Resonance Imaging is interesting for the evaluation of the early response. However, these are preliminary studies with quantitative measures realized by the region of interest (ROI) method. A response to neoadjuvant chemotherapy results in elevated values of apparent diffusion coefficients (ADC). The investigator's goal for this study is to evaluate the reliability of diffusion as tumor biomarker. Therefore, they will study the quantitative analysis of the diffusion-weighted magnetic resonance sequences in the pre-therapeutic assessment and the early and late follow-up of breast cancers under neoadjuvant treatment (chemotherapy, hormonotherapy...) within the CHU Brugmann hospital. The results of this analysis will be compared with the MRI results obtained at the end of the treatment and with the histology of the initial biopsy and the surgical specimen. The expected benefits are: - to establish correlations between apparent diffusion coefficients (ADC) values and histology - to observe changes in the ADC according to the type of response: ADC increase in the event of partial response, ADC stability in the event of non response, ADC decrease in the event of a progression, absence of restriction in the event of a complete response. - to confirm that diffusion weighted MRI within a short interval (after one cure, at one month) has a predictive value for the neoadjuvant chemotherapy (NAC) response.
The purpose of this study is to identify patients at risk for future heart failure using novel markers of early cardiac damage and determine if exercise training can improve these emerging markers as well as overall fitness and quality of life.
Non-randomized, Single Arm Clinical study to Evaluate the Safety and Effectiveness of MR Guided Focused Ultrasound Surgery in the Treatment of Early Breast Carcinomas
Radiotherapy (RT) has a major curative role in women with early breast cancer, and is recommended routinely after lumpectomy and selectively after mastectomy. It has contributed to a halving of breast cancer mortality in the UK over the last 2 decades despite ever-rising cancer incidence. RT in women with left-sided tumours often exposes the underlying heart to a damaging dose. The heart is very sensitive to RT, and there were 1-2 deaths from heart disease for every 100 breast cancer patients treated during the 1960s-70s. The situation has improved in recent years, but standard RT techniques still deliver significant radiation doses to heart tissue. Two potentially simple techniques reduce heart dose. In one, women are taught to breathe in deeply and to hold their breath for about 20 seconds while RT is given. The downward movement of the diaphragm pulls the heart away from the RT beam. In the other technique, women lie on their fronts, instead of on their backs as they normally do for breast RT. In this position, the breast falls away from the rib cage and reduces exposure of the heart. Neither technique is routinely available to women receiving breast RT in the UK for reasons that this research aims to address. The investigators need to: 1) confirm that patient position can be reproduced with millimetre precision every day using these techniques, 2) minimise costs of equipment, time and personnel required to support such techniques, 3) select the most appropriate technique for different patients and 4) train staff in centres across the UK to deliver techniques safely and effectively. By addressing all of these issues, the study aims ultimately to make heart-sparing RT available to all UK women that might benefit from treatment, thereby significantly reducing the burden of heart disease in breast cancer survivors.
Breast conservation surgery (BCS) is performed on patients with breast cancer with the intent to resect and completely remove the tumour while conserving as much of the surrounding normal tissue as possible. Currently, there is no way for surgeons to determine the adequacy of surgical resection in real-time during surgery; the assessment of surgical margins requires histological examination that is not available in real-time and is impractical in most clinical cases. This results in a re-excision rate of 23% among Canadian women in order to achieve optimal surgical margins. In addition, the presence or absence of cancer in tumor draining lymph nodes is recognized as a key element for breast cancer staging; however, lymph node dissection can be associated with overtreatment and morbidity (nerve damage and post surgical lymphedema) and histological analysis of nodes can be time consuming and thus delay subsequent procedures. In an effort to address these issues, we have designed and constructed, in collaboration with Sogang University, Seoul, S. Korea, a novel imaging system that performs three complementary imaging modalities (tri-modal): ultrasound (US), photoacoustic (PA) and fluorescence (FL). This first-in-human pilot study will recruit 10 breast cancer patients undergoing breast conserving surgery at Princess Margaret Hospital (Toronto, Canada). The study is designed to test our tri-modal (US, PA, FL) imaging technology in breast cancer patients. The overall goal is to obtain initial information on the technical feasibility of the tri-modal system in a peri-operative setting and to confirm the anticipated safety of the procedures. Additionally, it will provide initial data on the ability of this system to detect/localize primary breast cancer lesions and cancer-involved lymph nodes prior to surgery.
This randomized control trial will examine whether a well-controlled and monitored exercise intervention improves cognitive function in postmenopausal women with early-stage breast cancer and will explore whether neuroimaging metrics of brain health, pro-inflammatory biomarkers and symptoms (fatigue, sleep problems, depression, anxiety) mediate the effects of exercise on cognitive function. Furthermore, the study will explore whether the magnitude of the improvements in cognitive function are modified by estradiol levels.
