Breast Adenocarcinoma

This phase I/II trial tests the safety and tolerability of an experimental personalized vaccine when given by itself and with pembrolizumab in treating patients with solid tumor cancers that have spread to other places in the body (advanced). The experimental vaccine is designed target certain proteins (neoantigens) on individuals' tumor cells. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving the personalized neoantigen peptide-based vaccine with pembrolizumab may be safe and effective in treating patients with advanced solid tumors.

This study gathers information from the blood cells and tumor tissue during treatment with anti-HER2 therapies, such as trastuzumab, pertuzumab, lapatinib, or neratinib, in patients with HER2 positive stage I-IV breast cancer who are scheduled to start anti-HER2 therapy. The information gained from this study may help researchers better understand the relation between cell response and anti-HER2 therapies.

This study will test the safety, including side effects, and determine the characteristics of a drug called Rina-S in participants with solid tumors. Participants will have solid tumor cancer that has spread through the body (metastatic) or cannot be removed with surgery (unresectable).

This study evaluates changes in skin quality and self-esteem among breast cancer patients who are initiating aromatase inhibitor therapy.

This phase II trial tests the effectiveness of cannabidiol (CBD) plant extract (BRC-001) in improving joint stiffness and pain (arthralgia) in women with breast cancer taking aromatase inhibitors (AIs). AIs lower blood levels of estrogen in postmenopausal women to reduce breast cancer recurrence. Women on AI therapy may experience joint stiffness, pain and arthritis symptoms as a side effect of the medication. Some women stop AI therapy due to these side effects and do not receive the maximum benefit from the medication. CBD is derived from the same plant family as marijuana but is not associated with a "high" or mind-altering effect and is not habit-forming. Research in animals and humans indicates that CBD might decrease inflammation in joint tissues and may help reduce chronic pain in ailments such as arthritis. BRC-001 may reduce joint pain in women with breast cancer taking AIs.

The goal of this phase III randomized controlled trial (PRADAIIBE) is to assess if preoperative radiation therapy (Preop-RT) combined with immediate breast reconstruction (IBR) can safely improve both aesthetic and quality of life outcomes in breast cancer patients, compared to the standard of care (SoC) therapy consisting of post-mastectomy radiation therapy (PMRT) and delayed/immediate breast reconstruction, in a population of breast cancer patients with an indication of mastectomy and PMRT. The following hypotheses and outcomes will be assessed at the primary endpoint of 1 year of follow-up: * Efficacy: Does Preop-RT+IBR lead to a higher BREAST-Q satisfaction with breasts score (primary endpoint), EQ-5D-5L VAS score , EQ-5D-5L Index score, AIS-Total Aesthetic Score, or a shorter treatment duration compared to SoC? * Safety: Does Preop-RT+IBR lead to an increase in adverse events (general or surgical), a lower rate of pathologic Complete Response (pCR), or worse survival outcomes compared to SoC? \[Note: this study was not powered as a non-inferiority trial, all outcomes will be pooled internationally with parallel studies\] Eligible and consenting participants will undergo screening and baseline assessments. They will then be randomised between experimental (Preop-RT+IBR) and control (SoC) groups, in a 1:1 stratified variable block size design. Follow-up will take place at 3 months, 1, 2, 5, and 10 years after the last study treatment. At baseline and during each follow-up visit each participant will complete the Breast Q 'satisfaction with breasts' and EQ-5D-5L scales, photographs will be taken. During follow-up pCR will be assessed if applicable, adverse events will be registered, and oncological follow-up will be recorded.

The study is planned to observe and document the therapeutic decision-making process, treatment protocols, and clinical outcomes in patients with luminal breast cancer, whether they have undergone EndoPredict® testing or not

Breast cancer is the most common cancer worldwide, with over 2.2 million new cases diagnosed in 2020. Treatments such as chemotherapy often lead to a reduced exercise capacity, mainly due to cardiovascular and neuromuscular dysfunctions. This decline appears to be primarily caused by increased central fatigue, while peripheral fatigue remains unchanged. This imbalance suggests a hyperactivation of type III-IV afferent nerve fibers, which are involved in the metaboreflex-a mechanism that significantly influences cardiovascular responses during exercise. Two non-invasive methods, post-exercise circulatory occlusion (PECO) and passive leg movement (PLM), will be used to assess this hyperactivity in patients. Additionally, baroreflex function-crucial for regulating blood pressure-will be evaluated using a direct method to determine its sensitivity and reactivity. By comparing patients with healthy controls under submaximal stimuli, this study aims to better understand chemotherapy-induced cardiovascular dysfunctions. Ultimately, the goal is to design personalized exercise programs to restore cardiovascular function and reduce treatment-related side effects.

The goal of this clinical trial is to assess whether the addition of preoperative stereotactic body radiation therapy (SBRT) can improve pathological complete response (pCR) rates and safety in breast cancer patients who do not respond to initial neoadjuvant chemotherapy. The main questions it aims to answer are: * Can the combination of SBRT with chemotherapy increase pCR rates in non-responders to initial neoadjuvant chemotherapy? * Does the addition of SBRT to chemotherapy have acceptable safety and tolerability profiles? Participants in this trial will be early or locally advanced breast cancer patients who have shown no response to two cycles of standard neoadjuvant chemotherapy. They will be randomly assigned to either continue with the standard chemotherapy (control group) or receive SBRT in addition to continuing the standard chemotherapy (intervention group). The primary outcome measures will be pCR rate and breast conservation rate. Secondary outcomes will include 3-year local progression-free survival, overall survival, surgical complications, and treatment toxicities.

The purpose of this study is to find out if adding radiation therapy to routine medications for breast cancer helps in reducing and preventing the cancer from getting worse. Patients with a locally advanced breast cancer who cannot, or do not want to, undergo surgery are eligible to participate. Participation in this study does not prevent you from undergoing surgery in the future.

The study will include the prospective acquisition of optimized MR imaging data of prostate and breast patients treated with radiotherapy (RT). Within the prospective study, biological specimens from patients undergoing in-room biopsy before RT, will be collected. Histological evaluation and cell culture (and organoid preparation) will be conducted, and samples/organoids will be irradiated with RT for biological validation.

Spectral CT was used to prospectively collect medical images and clinical data related to breast cancer, evaluate the effect of image quality in the diagnosis of breast cancer, and evaluate the application value in the accurate staging of breast cancer, so as to provide a more accurate clinical basis for diagnosis, promote the development of individualized treatment, and ultimately improve the prognosis of patients.

The goal of this clinical trial is to compare the efficacy and safety in patients with lymph node-positive HR+/HER2- breast cancer. The main questions it aims to answer are: * Can the incorporation of intensified radiation to the tumor (tumor boost) enhance the pCR rate on the basis of neoadjuvant immuno-chemotherapy？ * Can it improve the level of residual cancer burden (RCB) and change the tumor immune microenvironment? and How safe will be the combined therapy? Participants will be randomly assigned to one of three treatment regimens: 1. Preoperative toripalimab combined with SBRT targeting both the primary tumor and axillary lymph nodes, followed by chemotherapy; 2. Preoperative toripalimab combined with SBRT focused solely on the primary tumor, followed by chemotherapy; 3. Preoperative toripalimab combined with chemotherapy alone. Following the completion of their respective treatment regimens, participants will proceed to undergo surgery. The effectiveness of the treatments will be assessed through pathological evaluations, as well as by measuring levels of residual cancer burden (RCB) and examining changes in the tumor immune microenvironment. The study aims to evaluate the safety of these combined treatment approaches and to determine if they offer superior efficacy compared to outcomes reported in previous studies.
