Active clinical trials for "Breast Neoplasms"

This phase I trial studies a new imaging technique called FAPi PET/CT to determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulate in normal and cancer tissues in patients with non-prostate cancer. The research team also want to know whether what they see on PET/CT images represents the tumor tissue being excised from the patient's body. The research team is also interested to investigate another new imaging technique called PSMA PET/CT. Participants will be invited to undergo another PET/CT scan, with the PSMA tracer (68Ga-PSMA-11). This is not required but just an option for volunteer patients. Patients who have not received an 18F-FDG PET/CT within one month of enrollment will also undergo an FDG PET/CT scan. The PET/CT scanner combines the PET and the CT scanners into a single device. This device combines the anatomic (body structure) information provided by the CT scan with the metabolic information obtained from the PET scan. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of, in the case of this research, 68Ga-PSMA-11 and 68Ga-FAPi, and 18F-FDG (if applicable). Because some cancers take up 68Ga-PSMA-11 and/or 68Ga-FAPi it can be seen with PET. CT utilizes x-rays that traverse the body from the outside. CT images provide an exact outline of organs where it occurs in patient's body. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors. The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers. PSMA stands for Prostate Specific Membrane Antigen. This name is incorrect as PSMA is also found in many other cancers. The function of PSMA is not well understood but imaging studies have shown that PSMA can be detected with PET in many non-prostate cancers. Imaging FAP with PET/CT may in the future provide additional information about various cancers.

The aim of this study is to evaluate the effect of CDK4/6 inhibitor treatment on the tumour choline metabolism as determined by [18F]D4-FCH PET/ computed tomography(CT) in breast cancer and to determine the suitability of [18F]D4-FCH-PET/CT as a non-invasive, early imaging biomarker for therapy response following CDK4/6 inhibitor treatment.

This pilot study is an investigation of feasibility of moderate dose omega-3 fatty acid supplementation in pre-menopausal women at high risk for breast cancer who are considering future pregnancy. The goal of this pilot study is to determine feasibility of the study, document compliance with omega-3 fatty acid supplementation in this population and identify novel biomarkers modulated by moderate dose omega-3 fatty acids in this population.

Investigators will evaluate the safety, tolerability, and feasibility of a risk-guided cardioprotective treatment strategy with carvedilol, as compared to usual care, in breast cancer patients undergoing treatment with doxorubicin, trastuzumab, or the combination.

Tissue will be procured during a standard of care procedure the patient will already be scheduled to undergo. A one time blood draw will be performed at this time and an optional rectal swab for biome analysis may occur. Follow Up will only consist of chart review to determine date of recurrence, metastases, and/or death

This research is being done because the investigators are looking for new and better ways to treat a type of breast cancer called triple negative breast cancer. This type of breast cancer can be more difficult to treat than other types of breast cancer as it does not respond to drugs such as hormonal therapies. One type of treatment that looks promising is immunotherapy using new drugs called immune checkpoint inhibitors. Immune checkpoints help to regulate the immune system and can stop the immune system from attacking cancer cells. Immune checkpoint inhibitors block this 'off-switch' and aim to help the immune system control the cancer. These drugs have been very effective in other cancers such as melanoma and are now being tested in breast cancer. In this study patients will receive an immune checkpoint inhibitor called avelumab. Half the patients on the study will also receive aspirin tablets for approximately 18 days as the investigators wish to compare the effects of avelumab alone versus in combination with aspirin. Patients will attend hospital approximately five times in order to complete all necessary study assessments. The first visit screens patients for suitability, after which a baseline visit will collect the first of two breast tissue biopsies. At the third visit a single dose of Avelumab will be given via an infusion (a drip in the forearm). Patients will then return approximately two weeks later for a second breast tissue biopsy before having a final follow up visit another two weeks later. Blood and urine samples will be taken at various visits throughout the study to help us learn more about the effects these treatments may have on the immune system and on breast cancer cells.

The aim of this observational study is to evaluate a dose fractionation scheme for APBI using external radiotherapy with modulated intensity technique (IMRT), with the possible impact on the quality of life of patients as it decreases the treatment number of sessions and improves the efficiency and accessibility.

This trial studies histamine and bone pain association in participants with breast cancer that has spread to the bone. Studying histamine levels in samples of blood from participants with breast cancer in the laboratory may help doctors learn more about reducing cancer bone pain and preventing further bone metastasis.

Basis: Brain metastasis is very common in breast cancer, and HER2 positivity is a risk factor for high incidence of brain metastasis, with approximately 50% of HER2+ MBC cases experiencing brain metastasis. The reason for this is that as the efficacy of HER2-targeted therapy improves, the survival of these patients significantly extends, leading to an increase in the occurrence rate of brain metastasis events in the late stage of MBC. In the systemic treatment of HER2+ breast cancer brain metastasis, various HER2-targeted drugs have been explored, but none have achieved satisfactory therapeutic effects. Therefore, it is imperative to explore new treatment options. ADC drugs have shown some efficacy in brain metastasis patients, and as a domestically developed ADC drug, trastuzumab vedotin has demonstrated good anti-tumor effects. The treatment model combining trastuzumab vedotin with small molecule TKIs has been rarely reported, so we are attempting to use the treatment model of trastuzumab vedotin combined with pyrotinib or neratinib to explore its efficacy and safety in patients with HER2-positive brain metastasis. Method: The plan is to recruit HER2-positive breast cancer patients with brain metastasis and use the treatment of trastuzumab vedotin combined with pyrotinib or neratinib (specific treatment drugs to be selected during the study). Procedure: All subjects will undergo screening, treatment, and follow-up periods, strictly adhering to relevant GCP regulations during the treatment process. Expectations: Through this study, preliminary efficacy and safety data of trastuzumab vedotin combined with pyrotinib or neratinib treatment will be provided for patients with HER2+ brain metastatic BC.

This prospective study recruits patients with ER+/HER2-, non-metastatic breast cancer who omit upfront surgery in favor of primary endocrine therapy for sample collection and prospective circulating tumor DNA (ctDNA) measurement to guide disease surveillance.
