The purpose of this study is to identify potential genetic and other molecular biomarkers of response to radiation therapy in breast cancer that may help to personalize breast cancer radiation treatment in the future.
Some tumors are difficult to treat with chemotherapy or radiation. One of the reasons is that areas of the tumor do not have many blood vessels, which makes it difficult for drugs to reach those areas. One way that researchers have recently tried to overcome this problem is by injecting special kinds of bacteria into the tumors. These bacteria have been genetically changed to remove the chemicals that are poisonous to humans, but are still able to cause tumor cells to break down and die. The idea is that these bacteria may be able to assist chemotherapy drugs in fighting cancer. The goal of this clinical research study is to find the highest tolerable dose of one of these bacterial therapies (Clostridium novyi-NT spores) that can be given in combination with pembrolizumab to patients with advanced solid tumors. The safety of this drug will also be studied, as well as whether it can help to control the disease. This is an investigational study. Clostridium novyi-NT is not FDA approved or commercially available. It is currently being used for research purposes only. Pembrolizumab is FDA approved for the treatment of melanoma and different types of head and neck and non-small cell lung cancers. It is investigational to use these drugs in combination with each other in various types of advanced cancers. The study doctor can describe how the study drugs are designed to work. Up to 18 participants will be enrolled in this study. All will take part at MD Anderson.
The purpose of this study is to find out whether lattice radiation therapy (LRT) is an effective radiation therapy technique when compared to standard stereotactic body radiation therapy (SBRT). The study will also study how the different radiation therapy techniques (LRT and SBRT) affect how many immune cells are able to attack and kill tumor cells (immune infiltration).
The goal of this clinical trial is to determine how the duration of hormone blocking (endocrine) therapy given prior to surgery (called "neoadjuvant" treatment) affects breast cancer. The main questions the trial aims is answer are: 1. How breast cancer responds to endocrine therapy given prior to surgery? 2. To predict tumor pre-operative endocrine prognostic index (PEPI) score for subjects enrolled in cohort B or C Participants with early-stage breast cancer (Stage I-III) who are eligible for Neoadjuvant Endocrine Therapy (NET) will be enrolled in the study. Participants will: * receive endocrine therapy as part of regular care for breast cancer * consent to samples of blood and tissue evaluation to determine how endocrine therapy effects the tumor * participate in this research anywhere from 2 weeks to 1 year, depending on duration of endocrine therapy and when surgery will be performed
This research study is evaluating the effect of exercise on markers in breast tissue and blood of premenopausal women who have been found to have dense breast tissue on mammogram.
This research trial studies whole exome sequencing in finding causative variants in germline deoxyribonucleic acid (DNA) samples from patients with peripheral neuropathy receiving chemotherapy for breast cancer. Studying samples of germline DNA in the laboratory from patients with peripheral neuropathy receiving paclitaxel for breast cancer may help doctors learn more about changes that occur in DNA and identify biomarkers related to peripheral neuropathy.
The aim of this clinical trial is to assess the feasibility and safety of ultrasound-guided vacuum-assisted excision (VAE) in the treatment of early breast cancer with Tis (carcinoma in situ) or T1 (maximum tumor diameter ≤2cm) and negative axillary lymph nodes on imaging. The main question it aims to answer is: * After VAE, when undergoing routine breast cancer surgery again, what is the complete resection rate of the lesion in the surgically removed tissue (pathologically confirmed), that is, the false negative rate of VAE? * Which type of breast cancer lesion has the highest complete resection rate? * Is it clear whether VAE can be applied in the treatment of early breast cancer with Tis or T1 and negative axillary lymph nodes on imaging? * Do patients with benign breast nodules who undergo VAE or are recommended for Vacuum-assisted breast biopsy (VABB) due to limited puncture and are diagnosed with breast cancer need to undergo surgery again? * The incidence of complications of VAE. Participants will: * Single early breast cancer subjects with Tis or T1 and negative axillary lymph nodes on imaging, after being fully informed and signing the informed consent form, enter the trial period after screening and being qualified. * After the subjects are confirmed to be enrolled, VAE biopsy resection is performed first. * Patients clearly diagnosed with breast cancer receive traditional radical mastectomy for breast cancer: Breast-conserving surgery or total mastectomy, sentinel lymph node biopsy or dissection in the axilla, assessment of whether the lesion has been completely removed based on postoperative pathology, and follow-up is conducted.
Patients with known or suspected primary or metastatic breast cancer with one lesion that is 1.0 cm in diameter or greater may be eligible for this study. Patients may participate in this study if they are at least 18 years of age. Up to 40 evaluable subjects will participate in a single imaging cohort. Patients will be stratified for analysis by breast cancer subtype with prioritization to recruit at least 10 estrogen-receptor-expressing (ER+) and 10 triple-negative breast cancers (TNBC). Participants may be treatment naïve or have received up to 3 weeks of treatment at the time of the \[18F\]F-Gln PET/CT scan. This is an observational study; \[18F\]F-GLN PET/CT will not be used to direct treatment decisions. While patients and referring physicians will not be blinded to the \[18F\]F-GLN PET/CT results, treatment decisions are made by the treating physicians based upon clinical criteria. \[18F\]F-GLN PET/CT imaging sessions will include an injection of \[18F\]F-GLN. Metabolism data will be collected. Pilot data will be collected to evaluate image quality and collect preliminary information on the uptake of \[18F\]F-GLN in breast cancer. Uptake measures will be compared to tumor markers of glutamine metabolism, when tissue is available. The safety of \[18F\]F-GLN will also be evaluated in all subjects.
This study aims to evaluate whether longitudinal multimodal ultrasound can accurately predict axillary pathological response in breast cancer patients who receive neoadjuvant chemotherapy. In this study, patients with biopsy-proven metastatic axillary lymph nodes will have a metallic clip placed in the positive node before chemotherapy. During and after treatment, the clipped lymph node will be monitored by ultrasound, including gray-scale imaging, shear wave elastography, and contrast-enhanced ultrasound. The changes in the morphological and functional features of the clipped node will be analyzed to establish a predictive model for axillary pathological complete response. The results are expected to help identify patients who may safely avoid unnecessary axillary lymph node dissection and improve individualized surgical decision-making.
In addition to TNM staging, the current management of breast cancer is based on conventional pathological features that categorize the disease into three molecular subtypes, each with significant prognostic implications in clinical practice: human epidermal growth factor receptor 2 (HER2)-positive, luminal (hormone receptor-positive and HER2-negative), and triple-negative breast cancers. The overexpression or amplification of HER2 is observed in 10-15% of breast cancer cases. This phenomenon often correlates with a more aggressive tumor behavior while also demonstrating an increased responsiveness to HER2-targeted therapies. However, the use of highly effective anti-HER2 drugs can significantly enhance the survival outcomes of these patients. Additionally, the expression status of HER2 is critical in determining the necessity for targeted therapy. Therefore, preoperative assessment of HER2 expression status has important therapeutic implications. Currently, clinical methods for assessing HER2 status in breast cancer before surgery include immunohistochemistry (IHC) tests and fluorescence in situ hybridization (FISH) measurements performed on core-needle biopsy specimens. However, these biopsy sampling techniques have inherent limitations, including sampling bias and an inability to fully represent intratumor heterogeneity. Additionally, the biopsy procedure can be uncomfortable and carries certain risks for patients. Tumour heterogeneity generally refers to the variations in angiogenesis, metabolism, gene expression, and other biological characteristics among tumors. Intratumoral heterogeneity (ITH) can manifest as signal differences in radiological images at the macro level. Investigators hypothesized that significant differences in biological characteristics and behavior exist between HER2-positive (HER2+) and HER2-negative (HER2 -) breast cancers, allowing for the distinction of these two types of tumours by identifying specific imaging features that reflect ITH. Dynamic contrast-enhanced MRI (DCE-MRI) is an effective imaging modality that provides temporal information regarding the dynamics of contrast agents in suspicious lesions while maintaining acceptable spatial resolution. It is particularly sensitive in detecting breast cancer lesions, especially those in dense breast tissue. DCE-MRI can indirectly reflect abnormal tumor vascular proliferation through the hemodynamic characteristics of the lesions. Radiomics is an emerging technology that involves extracting quantitative and reproducible features from medical images using high-throughput, sophisticated modalities that are often challenging to identify or quantify visually. These features, which may be linked to specific diseases, are analyzed using statistical or machine learning (ML) algorithms to create predictive models for tumor diagnosis, grading, efficacy evaluation, and prognosis prediction. ML has two important advantages over traditional statistical models. The goal is to…
The purpose of the study is to view what normal breast tissue looks like on an MRI and mammogram to help determine how it may affect the risk of developing breast cancer. The investigators will also compare the information collected from the questionnaire and medical records to help better understand how this may affect the risk of developing breast cancer. If a saliva or tissue sample is collected for future use, this information will enable us to study genetic risk factors as well.
This study is being done to help the investigators determine how accurate the sentinel lymph node biopsy (SLNB) procedure is in identifying residual cancer cells after neoadjuvant chemotherapy in patients presenting with locally advanced breast cancer.
Breast cancer, the most prevalent malignancy among women globally, is increasing in incidence. While non-metastatic breast cancer requires surgery, determining the optimal extent of resection remains challenging. Inadequate resection margins necessitate reoperation, leading to increased psychological stress, costs, and potentially compromised cosmetic outcomes and prognosis. Accurate preoperative assessment of resection extent is crucial and involves various factors, including imaging studies, physical examinations, tumor molecular subtypes, and intraductal carcinoma components. This prospective observational study aims to identify and integrate multiple predictive factors to enhance surgical planning and minimize reoperation rates in breast cancer patients.

This trial is a translational, open-label, monocentric and prospective cohort study of participants with breast cancer aiming to create a combined ESPRESSO (= organelle properties) phenotype and spatial proteomics data collection encompassing four cohorts: * TN eBC = cohort A, * HER2+ eBC = cohort B, * Luminal eBC = cohort C, * dnMBC = cohort D. In total 1050 participants will be enrolled in the study. Laboratory analysis (including ESPRESSO technique) will be conducted on the biological specimen collected during this study. The primary objective is to describe the amount of fatty acids accumulated in lipid droplets, within the four cohorts. As a secondary objective, the analysis will expand to other organelles like lysosomal acidity and nuclear organization. The study is due to last 9 years (4 years of recruitment and 5 years of study participation)
This is a Phase 1b/2, open-label, parallel-arms pilot study in men and post-menopausal women with hormone receptor positive (HR+), HER2- advanced or metastatic breast cancer with an alteration in the PI3K pathway, including a mutation of the PIK3CA gene, PTEN loss, or AKT1 mutation, designed to determine the safety of evexomostat (SDX-7320) plus standard of care treatment alpelisib (BYL-719) or capivasertib and fulvestrant (each combined, the 'triplet therapy'), to measure the severity and number of hyperglycemic events, and to assess clinical, anti-tumor benefit of the triplet therapy. The purpose of this study is: * to characterize the safety of the triplet drug combination consisting of either alpelisib or capivasertib (per the treating oncologist's choice) and fulvestrant plus evexomostat, * to test whether evexomostat, when given in combination with either alpelisib or capivasertib and fulvestrant will reduce the number and severity of hyperglycemic events and/or reduce the number or dose of anti-diabetic medications needed to control the hyperglycemia for metabolically normal patients and those deemed at risk for capivasertib and alpelisib-induced hyperglycemia (insulin resistance, as measured by HOMA-IR, baseline elevated HbA1c or well-controlled type 2 diabetes), and * to assess preliminary anti-tumor efficacy for each combination and changes in key biomarkers and quality of life in this patient population.
Lymphedema is a persistent and chronic swelling condition that commonly develops after breast cancer surgeries involving axillary lymph node dissection (ALND). This condition causes pain, heaviness, and swelling in the upper limb, which severely limits shoulder mobility and functional performance in daily life tasks. While manual lymphatic drainage (MLD) is widely utilized to stimulate lymphatic flow and reduce tissue swelling, the added therapeutic benefit of combining it with deep breathing exercises remains less evaluated. This study is a randomized controlled trial designed to investigate whether combining diaphragmatic breathing exercises with manual lymphatic drainage is more effective than manual lymphatic drainage alone. The main goals of this study are to determine if this combined intervention provides greater reductions in arm circumference and subjective pain levels while significantly improving upper extremity range of motion and overall functional ability in female patients recovering from a radical mastectomy.
This is a multicenter, open, randomized, comparison study. Triple-negative breast cancer (TNBC) is a term applied to breast cancer cases that have \<1% expression of the estrogen receptor (ER) and the progesterone receptor (PR) and do not over express HER2. Neoadjuvant therapy is often used to reduce the size of tumors, especially in locally advanced tumors. The purpose of this therapy is to make part of patients operable and to facilitate breast-conserving surgery. The purpose of this study is to assess the efficacy and safety of the following two proposals: nab-paclitaxel plus carboplatin versus nab-paclitaxel plus epirubicin, in order to provide support for rational clinical application. The total number of patients to be included in this study is 520 patients.
