Filter by:Rationale:To improve the definition of the target volume for radiotherapy of the chestwall after different types of mastectomy, the exact localization of regions at risk for a local recurrence should be known. However, there are currently insufficient data in literature showing where local recurrences occur after different types of mastectomy. Objective: The primary objective of the proposed study is to determine whether the spatial, location of a breast cancer recurrence after mastectomy, differs for different types of mastectomy. Study design: Retrospective study evaluating spatial location and site of recurrences after mastectomy. Study population: The investigators aim to include all breast cancer patients treated with mastectomy in the Netherlands between 2003- 2008, and known to have experienced a local recurrence as the first site of failure. Primary endpoint: Spatial location of local recurrence (e.g., primary tumour bed, scar, skin, subcutaneous, nipple, areola, pectoral muscles).
The purpose of this study was to evaluate the effect of mindfulness-based meditation and yoga on stress, self-esteem, body image and sexual adjustment in breast cancer patients.
A retrospective study of de-identified (to preserve patient privacy) patient information from the SEER-Medicare Database to compare overall survival of first line palbociclib + aromatase inhibitor (AI) therapy versus AI therapy alone treatment in women or men aged 65 and older with newly diagnosed hormone receptor positive/human epidermal growth factor receptor 2 negative (HR+/HER2-) metastatic breast cancer (MBC) in the United States
Rationale: Breast cancer patients are increasingly treated with neoadjuvant chemotherapy for various reasons. These women receive chemotherapy before any surgery is performed. Many of these tumors need preoperative seed localization to help guide the surgeons to the site of the tumor within the breast. The interest is shifting towards to use of non-radioactive seeds, such as the magnetic seeds used in this study. A drawback of these seeds is the fact that they cause large susceptibility artifacts on (magnetic!) MRI of the breast. Breast MRI is the most accurate modality to monitor response to therapy of these women. CEM, an emerging breast imaging technique, has shown to achieve comparable results with regard to response monitoring but uses no magnetic fields. Hence, CEM might be an attractive alternative response monitoring tool in patients treated with neoadjuvant chemotherapy and having a magnetic seed a surgical marker. To this point, however, no study in humans has confirmed that this is indeed the case. Objective: To test whether the use of magnetic localization seeds causes image artifacts on CEM. Study design: Observational feasibility study. Study population: Women (>18 years) able to provide written informed consent and recently diagnosed with (non-palpable) breast cancer or ductal carcinoma in situ (DCIS), who are primarily treated with surgery. Intervention (if applicable): Image-guided placement of a magnetic seed (Sirius Pintuition) prior to surgery, including control imaging to confirm the correct location of the seed relative to the breast abnormality. In usual patient care this is performed with full-field digital mammography (FFDM), but in this study this control image will be performed with the system in 'contrast-enhanced mammography' or CEM mode, but without using intravenous administration of iodinated contrast agent because the purpose is not repetition of diagnostic imaging, but to rule out any artifacts caused by the seed on CEM. The investigators estimate to include twenty patients to confidently test the hypothesis that magnetic seeds do not cause disturbing artifacts on CEM examinations. Main study parameters/endpoints: The primary study aim will be to test whether the magnetic seeds caused any disturbing artifacts on CEM images. As secondary study, the investigators will document technical success rate of seed deployment and retrieval during surgery, including the assessment of the surgical margins (positive or negative).
Prospective single centre study of patients with DCIS that have undergone breast conservation surgery.
This study aims to establish a holistic framework for continuous cancer survival surveillance in Russian regions with high-quality population-based cancer registry data. The data from the population-based cancer registries of the Northwestern regions of Russia will be used to assess net and cause-specific survival trends.
This study intends to include HER2-positive metastatic breast cancer patients (with or without brain metastasis) who have become resistant to previous treatment with trastuzumab. It will use pertuzumab in combination with pyrotinib and capecitabine to observe efficacy and safety. The choice of capecitabine as the chemotherapy drug is mainly based on the following reasons: ① it has been less commonly used as neoadjuvant treatment, making it less prone to cross-resistance; ② its oral formulation is convenient for administration, making it more acceptable to patients; ③ previous studies have shown good efficacy when combined with pyrotinib; ④ previous research in breast cancer patients with brain metastasis has also demonstrated certain effectiveness. It is hoped that through this study, preliminary evidence can be provided for the dual-target treatment of original Chinese drugs, as well as the treatment of HER2+ MBC after resistance to trastuzumab, and the addition of new data for patients with brain metastasis.
This randomized control trial aims to analyze the changes in cardiovascular endurance and quality of life domains for breast cancer survivors in the United Arab Emirates using a long-term 2-month physical rehabilitation program adapted from the BREX protocol.
The purpose of this real-world study is to understand the use of palbociclib as first treatment for Hormone receptor positive (HR+) and Human epidermal growth factor receptor 2 negative (HER2-) metastatic breast cancer in Canada (PALCAN). The real-world study is not a research study. It involves real patients who receive medicines prescribed by their doctors in the real world. Metastatic breast cancer is the type which has spread from breast to other organs. HR positive stands for Hormone-receptor cells that have a protein on their surface that binds to one of 2 types of hormones. They are estrogen or progesterone. Both these hormones help cancer cells grow. HER2 negative describes cells that have a small amount or none of a protein called HER2 on their surface. In normal cells, HER2 helps control cell growth. Cancer cells that are HER2 negative may grow more slowly and are less likely to come back or spread to other parts of the body. This study will mainly measure: - duration of treatment (from start of treatment till end of treatment) among a group of patients taking palbociclib (Ibrance) in combination with hormone therapy as first line treatment for HR+ HER2- metastatic breast cancer.
