Filter by:In the context of breast cancer, in case of an indication for chemotherapy, anthracycline-based protocols make it possible to improve the overall survival of patients most at risk. The frequency of anthracycline-related cardiac toxicities (ARCT) increases with the cumulative dose of anthracyclines administered and explains, at least in part, the increased risk of cardiovascular (CV) mortality in patient populations treated for breast cancer. The numerous indications for anthracycline-based protocols have made it possible to describe ARCT, among which heart failure with reduced left ventricular ejection fraction (LVEF) remains one of the most comorbid. In addition to left ventricular dysfunction, anthracyclines have been associated with endothelial dysfunction, microvascular damage and myocardial ischemia responsible for dilated cardiomyopathy. Different approaches have attempted to better understand and prevent these ARCT. However, apart from the notion of limit cumulative doses of anthracyclines, few of them have made it possible to screen patients at risk and prevent the onset of cardiac dysfunction. The search for biological markers (Troponin I, BNP) or ultrasound markers (Longitudinal Strain) warning of subclinical cardiac damage is still struggling to assert its interest due in particular to significant inter- and intra-observer variability. Therapeutically, ACE inhibitors and beta-blockers have shown a significant improvement in the incidence rate of LVEF reduction during adjuvant treatment of breast cancer. However, despite equivalent signals in other cancers, the studies conducted to date are insufficiently powered and the role of these treatments is limited to secondary prevention or the treatment of objective heart failure. It remains necessary to determine new biological markers that can identify patients most at risk of ARCT and thus adapt our therapeutic prevention strategies. To do this, it is first necessary to better understand the pathophysiology underlying these ARCT. The objective of this study is to determine whether expression of the receptor among endothelium and circulating cells, SGLT2, is associated with an additional risk of presenting cardiovascular toxicity following treatment with anthracycline. If this association is demonstrated, it will then be possible to better screen and prevent these cardiovascular complications.
The Understanding and Addressing Rejection of Personalized Cancer Risk Information study is a longitudinal observational study conducted to understand the nature of phenomenon of personalized cancer risk rejection in the context of mammography screening.
The purpose of this study is to test the safety and effectiveness of a sequence of drugs (a Taxane plus Trastuzumab plus Pertuzumab followed by Trastuzumab Deruxtecan, followed by Tucatinib plus Ado-Trastuzumab Emtansine (T-DM1), followed by Trastuzumab plus Pertuzumab plus Tucatinib) in HER2+ Breast Cancer. The study will help investigators understand whether first intensifying therapy for a specific period and then stopping treatment is safe and effective for participants. The names of the study drugs involved in this study are: - Paclitaxel (a type of anti-microtubule agent) - Docetaxel (a type of anti-microtubule agent) - Nab-Paclitaxel (a type of anti-microtubule agent) - Trastuzumab (a type of IgG1 kappa monoclonal antibody) - Pertuzumab (a type of monoclonal antibody) - Trastuzumab Deruxtecan (a type of HER2-directed antibody drug conjugate) - Tucatinib (Tyrosine Kinase HER2 Inhibitor) - Ado-trastuzumab emtansine or T-DM1 (a type of HER2-targeted antibody-drug conjugate)
This study aims to enroll refractory breast cancer patients. Patient-derived organoid will be established, and drug sensitivity test will be conducted to intervene in the selection of clinical treatment plans. Efficacy evaluation and prognosis analysis will also be conducted. It is hoped that this study will provide a basis for the development of personalized treatment plans.
An interventional, non-pharmacological, monocentric study evaluating the effectiveness of cognitive rehabilitation in counteracting chemotherapy-induced cognitive impairment (CRCI) in women with operable breast cancer treated with neo-adjuvant therapy and/ or adjuvant therapy.
The efficacy and safety of zanidatamab in combination with physician's choice of chemotherapy compared with trastuzumab in combination with physician's choice of chemotherapy will be evaluated for the treatment of participants with metastatic HER2-positive breast cancer who have progressed on, or are intolerant to, previous T-DXd treatment.
Breast cancer is a major threat to women's health, and chemotherapy is one of the most important treatment method. Chemotherapy is cytotoxic , and has a positive tumor immune effect. However, it is worth noting that anxiety caused by breast cancer itself and adverse reactions of chemotherapy not only affects the patients' quality of life, but also reduces the treatment compliance and even survival benefits of patients. Previous literatures have shown that aromatherapy may improve chemotherapy-induced anxiety and even affect anti-tumor immunity. Therefore,we envisage that aromatherapy conbimed with chemotherapy in the treatment of breast cancer in clinical practice has the advantages of improving efficacy and survival. However, there is still a lack of relevant clinical studies. We planned to design a prospective clinical trial to evaluate the efficacy and safety of aromatherapy combined with chemotherapy on anxiety, relevant sympathetic neurotransmitters and tumor immunity in breast cancer patients.
This randomized, double-blind, placebo-controlled pilot study aims to evaluate the efficacy and safety of GcMAF in reducing nagalase levels and improving clinical outcomes in female patients with metastatic breast cancer over six months. Sixty patients will be randomized into two groups receiving either weekly GcMAF or placebo injections. The primary endpoint is the change in serum nagalase levels from baseline to six months. Secondary endpoints include clinical status, quality of life, adverse effects, and markers of inflammation and immune activity. Tumor response will be assessed using RECIST criteria, and quality of life will be measured with the EORTC QLQ-C30 questionnaire. Immune and inflammation markers will be evaluated using flow cytometry and ELISA. Adverse events will be monitored and categorized according to severity. Inclusion criteria include confirmed metastatic breast cancer, completion of one line of systemic therapy, adequate organ function, and elevated serum nagalase levels. The study will involve baseline measurements, monthly assessments, and final evaluations to compare changes in nagalase levels and other clinical outcomes between the GcMAF and placebo groups.
This phase II trial tests how well tamoxifen and pegylated liposomal doxorubicin works in treating patients with triple negative breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic) or that has spread to nearby tissue or lymph nodes (locally advanced) and is unable to be operated on (inoperable). Tamoxifen works by blocking the effects of estrogen in the breast. This may help stop the growth of tumor cells that need estrogen to grow. Doxorubicin is in a class of medications called anthracyclines. Doxorubicin damages the cell's DNA and may kill cancer cells. It also blocks a certain enzyme needed for cell division and DNA repair. Liposomal doxorubicin is a form of the anticancer drug doxorubicin that is contained inside very tiny, fat-like particles. Liposomal doxorubicin may have fewer side effects and work better than other forms of the drug. Giving tamoxifen and pegylated liposomal doxorubicin together may work better in treating patients with metastatic or inoperable, locally advanced triple negative breast cancer than giving either of these drugs alone.
Our study is aimed to evaluate the efficacy and safety of novel ADCs named SHR-A1811 and SHR-A1921 combined with adebrelimab in HER2-negative advanced breast cancer.
