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.
This is a single-arm pilot proof of concept, open-label clinical trial. Twenty-five subjects will be enrolled in 6 sites. Metastatic breast cancer patients with disease progression to bevacizumab maintenance treatment will be potential candidates. Bevacizumab maintenance will be considered as six weeks of bevacizumab treatment in monotherapy, with hormonal treatment or combined with chemotherapy in the context of previous bevacizumab plus chemotherapy regimens. When progression to bevacizumab maintenance treatment occurs, patients will enter the trial and will start receiving DURVALUMAB 10 mg/kg Q2W IV infusion plus bevacizumab 10mg/kg IV infusion every 2 weeks. The patients will undergo a tumor biopsy before the first dose of DURVALUMAB, and after one month of combined treatment - the blood sampling will continue on a monthly basis. The treatment will continue until disease progression.
Chemotherapy in clinically node positive breast cancer patients is increasingly administrated in a neoadjuvant setting. The standard treatment regimen in these cases is then: neoadjuvant chemotherapy (NAC) followed by breast surgery and an axillary lymph node dissection (ALND). NAC results in axillary pathologic complete response (pCR) in 1 out of 3 patients, indicating a complete absence of axillary metastases after completion of NAC. In such events, ALND can be regarded as overtreatment that creates unnecessary morbidity. Less invasive axillary surgery which can accurately assess axillary pCR is therefore preferred over standard ALND in all patients. In case of detection of remaining axillary lymph node metastases by this less invasive axillary surgical procedure, completion axillary treatment is standard of care. The novel RISAS procedure is introduced as a possible less invasive axillary staging procedure. RISAS procedure contains Radioactive Iodine Seed localisation in the Axilla in axillary node positive breast cancer combined with a Sentinel node procedure. The iodine seed in the axillary lymph node metastasis will be placed prior to start of NAC.
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.
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
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.
