Filter by:Despite modern surgical and medical treatments, breast cancer can re-occur and lead 20% of patients to death. During the last 20 years, pre-clinical studies have shown that treatment failures may be due to the presence of a sub-type of cancer cells, the cancer stem cells, which are resistant to chemotherapy and radiotherapy. By chance, doxycycline, an old, inexpensive and safe molecule seems to target effectively these cancer stem cells. This study proposes to check for the clinical efficacy of doxycycline to target the cancer stem cells and improve the response to neoadjuvant chemotherapy in ER+/HER2- breast cancers.
This phase II trial tests how well turkey tail mushroom (TTM) works in treating post-menopausal women with HER2-negative, estrogen receptor (ER)-positive breast cancer undergoing surgery. TTM is a common mushroom. In traditional Chinese medicine, it is used for enhancing function and removing toxins, as well as for cancer, hepatitis, and infections. There is previous evidence of significant tumor shrinkage occurring in the 2-month window between diagnosis and surgery in women who have taken TTM. Giving TTM may be effective in treating post-menopausal women with HER2-negative, ER-positive breast cancer undergoing surgery.
Heroes is a multicentre, national, non-randomized, open-label, phase 2 study. The goal of this clinical trial is to evaluate the feasibility of therapeutic de-escalation in HER2-positive metastatic breast cancer with disease controlled after 2 years of maintenance treatment with anti-HER2 targeted therapy AND ctDNA negative testing. The main question it aims to answer is : • Is it possible to identify patients for whom temporary or permanent discontinuation of treatment is possible without impacting prognosis?
Breast cancer is the most prevalent cancer worldwide and the leading cause of cancer death among women in Chile. The Aurora intervention program is designed to improve the quality of life and mitigate the physical consequences of breast cancer in patients undergoing neoadjuvant chemotherapy. It aims to promote physical activity through a human-centered design product system, incorporating elements of personal motivation, peer learning, and community engagement in alignment with the COM-B model. In a 9-week randomized controlled trial, we will include 30 female patients under 70 years undergoing neoadjuvant therapy for breast cancer in the Metropolitan Region of Chile. Baseline and post-intervention measurements will assess biopsychosocial breast cancer effects through a questionnaire as well as adverse physical effects through functional capacity tests. Biological consequences will be evaluated through lipid profiling, inflammation biomarkers, and tumor progression. In addition, Aurora's patient perception of behavior change will be addressed by analyzing the patient's records in a journal. Moreover, the perceived value of Aurora's design attributes influencing behavior change will be studied through in-depth interviews. Preliminary results describe Aurora's design process and indicate that it is well-received by patients, especially as its logbook is a valuable tool for self-reflection and progress tracking. The study anticipates the confirmation that significantly higher physical activity, improved quality of life, and enhanced functional capacity will be attained in the intervention group. The Aurora intervention program represents a novel approach to support breast cancer patients undergoing chemotherapy, emphasizing physical activity, peer learning, and self-reflection. The integration of the behavior change COM-B model and a human-centered design provides a facilitating tool for tailored interventions for breast cancer patients' needs. Yet, the potential correlation between physical activity, fatty acid metabolism, and chemotherapy response necessitates further exploration. The Aurora intervention program shows promise as a supportive tool for breast cancer patients undergoing neoadjuvant chemotherapy. Further research is imperative to evaluate the intervention's impact on patient outcomes, refine the design based on user feedback, and explore potential relationships among physical activity, fatty acid metabolism, and chemotherapy response.
This study is a Phase II, multi-site, randomized, open-label clinical study to evaluate the safety, efficacy, and pharmacokinetics (PK) of BNT327 at two dose levels in combination with chemotherapeutic agents in the first- and second-line treatment of participants with locally advanced/metastatic triple-negative breast cancer (mTNBC).
The study is to assess the safety, efficacy and pharmacokinetic Behavior of Leuprolide Injectable Emulsion for Premenopausal Breast Cancer Subjects.
Studies have reported that tumors with the same immunogenic mutations may induce T cell receptor (TCR) domains with similar antigen recognition functions. By assembling the complementarity-determining region 3 (CDR3) of TCRs from RNA-seq data and correlating them with 9142 samples from TCGA data, an in-depth analysis of the TCR pool in the tumor microenvironment found a strong correlation between the CDR3 sequences of tumor-infiltrating T cells and tumor mutation burden. Fairfax et al. found that in patients responding to tumor immunotherapy, the TCR immune pool of CD8+ T cells produces many clones with extremely high abundance (exceeding 0.5%) . Cader et al. also found significant changes in the TCR immune pool of patients with Hodgkin's lymphoma responding to PD-1 tumor immunotherapy. Based on these theoretical foundations, evaluating the dynamic changes of the TCR immune pool is expected to be used to analyze the immune characteristics and changes in diseases such as malignant tumors.
This is a randomized, controlled, open-label, phase III study to explore the efficacy and safety of Apatinib in combination with standard first-line endocrine therapy for the HR+/ HER2-SNF4 subtype of advanced breast cancer. The study was used to explore the efficacy of Apatinib in combination with standard endocrine therapy.
Breast cancer is the most common cancer in women globally, with 2.3 million new cases diagnosed in 2020. Hormone receptor positive (HR+), human epidermal growth factor receptor 2 negative (HER2-) breast cancer is the most prevalent subtype, comprising 69% of all breast cancers in the USA. Within the tumor immune microenvironment, a higher intensity of myeloid cell infiltration and low levels of lymphocyte infiltration have been associated with worse outcomes. Markers in peripheral blood have emerged as predictive biomarkers that can be easily obtained non-invasively and at low cost. Experiments have confirmed the relative components of these tests (such as the immune cells) directly or indirectly participated in tumour occurrence, development, and immune escape, underscoring the potential use of laboratory tests as tumour biomarkers
The primary goal of the DEFINITIVE trial is to demonstrate the effectiveness of the HER2DX diagnostic assay in enhancing the management of patients with early-stage HER2- positive breast cancer. Patients randomized to arm A will receive adjuvant treatment by physician´s choice, blinded to the diagnostic HER2DX test results. Patients randomized to Arm B will receive personalized treatment according to HER2DX results.
