To prospectively evaluate the impact of HER2DX on the decision-making processes of the treating physicians and especially among the routine multidisciplinary tumour board, in defining type and setting of systemic therapy administration in patients with stage I-III HER2+ BC, and the degree of clinician's confidence in the treatment recommendation.
NCT07387445
This study is being done to better understand how time restricted eating (eating all food in an 8 hour window) can help a person receiving chemotherapy treatment for breast cancer, stages I-IV. We want to find out if time restricted is feasible and acceptable to individuals starting chemotherapy for breast cancer. We will test 3 different eating window options compared to a control group for 24 weeks.
NCT06791018
This study will examine whether a mobile app increases exercise levels in breast cancer survivors after treatments, reduces fatigue, and improves physical functions. This experimental study has 200 participants placed into one of two groups. One group will be asked to use the cancer-specific exercise app over 12 weeks, and the other group will receive the cancer exercise guidelines. Exercise will be measured by self-report questionnaires before and after the intervention and three months later. Self-report questionnaires will measure fatigue and quality of life. This research will determine whether a simple mobile app helps increase exercise in breast cancer survivors. Mobile apps to increase exercise may be provided to all breast cancer survivors after treatments to help them recover and possibly improve survival.
NCT06970912
* This is a Phase II, multicenter, randomized clinical trial evaluating a ctDNA-guided approach to de-escalate adjuvant chemotherapy in patients with hormone receptor (HR)-positive, HER2-negative early-stage breast cancer. The study aims to determine if combining the CDK4/6 inhibitor Dalpiciclib with endocrine therapy can reduce the need for chemotherapy while maintaining clinical benefits. * Key Details ： 1. Participants: 393 women (aged 18-75) with early-stage HR+/HER2- breast cancer at high risk of recurrence (e.g., tumor size ≥2 cm, lymph node involvement, or high-grade tumors). 2. Design: Patients are randomized 1:4 to two groups: Group A (Chemotherapy) : Receives 4 cycles of taxane-based chemotherapy before surgery. Group B (Experimental) : Receives Dalpiciclib + aromatase inhibitor (AI) for 4 cycles pre-surgery. Post-surgery, treatment is adjusted based on ctDNA results. 3. Primary Goals ： Assess ctDNA clearance rate (conversion from detectable to undetectable ctDNA) after neoadjuvant therapy in Group B. Evaluate 3-year event-free survival (EFS) in Group B (e.g., freedom from cancer recurrence, progression, or death). Secondary Goals ： Safety of Dalpiciclib + endocrine therapy. Tumor response rates (e.g., complete cell cycle arrest, pathological remission). Correlation between ctDNA clearance and long-term outcomes. * Why This Matters ： Current guidelines recommend chemotherapy for high-risk HR+ breast cancer, but it often causes significant side effects. This study explores a personalized approach using ctDNA-a blood-based biomarker-to identify patients who may safely avoid chemotherapy without compromising survival. If successful, it could shift clinical practice toward less toxic, targeted therapies for eligible patients.
NCT07331506
Cancer continues to be one of the most significant public health issues worldwide. Thanks to early detection, the mortality rate of certain types of cancer has decreased significantly. However, the lack of accessible, low-cost, non-invasive, non-toxic, and easy-to-implement diagnostic methods results in late diagnoses, leading to 1 in every 6 people dying from cancer today. MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression and are found both inside cells and in bodily fluids such as blood and urine. Several studies have demonstrated their role in human diseases, especially cancer, where tumors release miRNAs into the bloodstream that can be used as biomarkers for early detection. The research and development team at Oncoliq SAS identified a panel of miRNAs associated with breast cancer, with a detection performance of 82% sensitivity and 83% specificity, validated in exploratory and preliminary confirmatory studies. These results led to the filing of a patent based on liquid biopsy technology. The objective of this protocol is to establish a panel of miRNAs for the early detection of breast cancer using samples from breast cancer patients and a cancer-free control group. Validation of the miRNAs will be carried out through RT-qPCR. This stage constitutes the analytical validation of the biomarkers, with the goal of developing an algorithm capable of classifying individuals with and without breast cancer. In future stages, a pilot clinical trial is planned to evaluate test implementation and clinical validation.
NCT06924788
In a sample of Alabama breast cancer survivors, the proposed study tests the feasibility and acceptability of a stress management program that has been shown to improve health and wellbeing in a general population of patients with a history of breast cancer. The study will also get feedback (e.g., implementation barriers and facilitators) from relevant stakeholders.
NCT07269691
This study is an open-label, controlled, multicenter phase III clinical trial designed to evaluate whether the use of iodine-125 radioactive seed markers can improve treatment response for patients with early or locally advanced breast cancer undergoing neoadjuvant therapy. Neoadjuvant therapy is widely used for breast cancer to shrink tumors, increase the chances of breast-conserving surgery, and help determine the most effective postoperative treatments. Achieving a pathological complete response (pCR) after neoadjuvant therapy is strongly associated with better long-term outcomes. In this study, qualified participants will be randomly assigned in a 1:1 ratio to either the experimental group or the control group. Experimental group: Patients will receive placement of iodine-125 seed markers in the primary breast tumor and biopsy-proven positive axillary lymph nodes before starting neoadjuvant therapy. Control group: Patients will undergo standard neoadjuvant therapy without seed placement. All participants will then complete neoadjuvant therapy followed by surgery. Pathological evaluation will determine whether the cancer has completely disappeared. Long-term outcomes, including invasive disease-free survival, will be followed for at least five years. The goal of this study is to determine whether radioactive seed marking can increase the rate of pathological complete response and improve prognosis in patients receiving neoadjuvant therapy for breast cancer. The study will also explore whether iodine-125 seeds may activate immune responses that contribute to treatment effectiveness.
NCT06885671
Partial Breast Irradiation (PBI) is a targeted radiation approach commonly administered post-lumpectomy, specifically targeting the tumour bed. This targeted therapy reduces the exposure to other nearby tissues such as lungs, heart, and chest wall. However, traditional PBI treatment involves lengthy multiple fraction courses which presents a burden to patients from rural and remote communities, who must travel long distances to receive high quality cancer care. The purpose of this study is to compare single fraction (SF) PBI vs. multiple fraction (MF) PBI.
NCT07042568
This study aims to evaluate the effect of nursing education provided to women diagnosed with breast cancer undergoing chemotherapy on their quality of life and the severity of oral mucositis (mouth sores). The main questions this study aims to answer are: 1. Does nursing education aimed at preventing oral mucositis in women diagnosed with breast cancer have an effect on quality of life? 2. Does nursing education aimed at preventing oral mucositis in women diagnosed with breast cancer have an effect on the severity of oral mucositis? The researchers will evaluate the effect of nursing education on quality of life and oral mucositis severity by randomly assigning one group to receive education and the other group to not receive education. Participants: When they come to receive their chemotherapy treatment (on the first day of the evaluation), the researcher will fill out a scale measuring quality of life and scales checking the condition of the oral mucosa. Participants in the education group will receive education from the researchers using an education booklet prepared by the researchers, and the booklet will remain with the participants. On days 7 and 14, the researcher will provide telephone consultation. On the 21st day, when the final evaluation will be conducted, data will be collected from participants through the scales.
NCT06777420
Preoperative chemotherapy has been shown to be at least as effective as postoperative chemotherapy in breast cancer patients and has seen increased use over time. The decision regarding neoadjuvant treatment is complex, as various aspects need to be considered, and the patient's role in the decision-making process is central. The information provided by doctors to patients about preoperative treatment can be complicated, including details about treatment options, treatment plans, and side effects. If this information is not conveyed adequately, there is a risk of misunderstandings, which can lead to increased anxiety and stress for patients regarding their decisions. In oncology, question prompt lists (QPL) have been used as a tool to support patients by improving the information conveyed by doctors in various contexts where complex decisions need to be made. Studies have shown that QPL can facilitate better information exchange. However, their use in discussions about preoperative treatment for breast cancer patients has not been studied. Furthermore, evidence from randomized studies on the use of QPL in clinical practice is very limited. The aim of this study is to investigate whether the use of QPL during patient consultations involving discussions about neoadjuvant chemotherapy can improve information exchange in various aspects: understanding of the treatment; anxiety about the decision; participation in the decision-making process; patient-doctor communication; and decision-related conflict.
NCT06890221
The goal of this clinical trial is to measure the mean difference of phase angle after nutritional intervention in breast cancer patients. The main question it aims to answer is: 1\. Can perioperative nutrition interventions improve phase angle in relation to other bioimpedance parameters, handgrip strength and surgical outcomes in breast cancer population? Researchers will compare oral nutritional supplement to a placebo to see if oral nutritional supplement can improve phase angle. Participants will: 1. Be randomized into either arm 2. Take oral nutritional supplement or placebo according to the result of randomization for 7 days preoperatively and 30 days postoperatively 3. Have their measurements (weight, height, phase angle, handgrip strength) done at least 7 days preoperative, 1 day preoperative and 30 days postoperative
NCT00569049
This is a research-based study that is looking at the biologic features of breast tissue, lymph node tissue, or blood in order to study breast cancer development growth, and spread. Through tissue and/or blood samples we hope to gain further knowledge and understanding of how to improve diagnosis and treatment of breast cancer by identifying the molecular markers that predict clinical outcome and response to therapy.
NCT06806072
Endocrine therapy is the mainstay of adjuvant therapy in premenopausal women with hormone receptive-positive (HR+) breast cancer as it has been demonstrated that it reduces long-term recurrences and increases survivial. However, this therapy, which suppresses estrogen production and estrogen-induced effects, is associated with the development of joint pain which can significantly reduce quality of life and lead to treatment discontinuation. The main question the study aims o answer is: Can balneotherapy (BT) alleviate muscle-skeletal pain (primary objective) derived from endocrine therapy and improve quality of life (secondary objective) in young women with HR+ breast cancer?
NCT06762977
The goal of this observational study is to assess the prognostic value of a genomic classifier (S18) and its refined version (S\*) in women with early-stage HER2-positive breast cancer. The study aims to determine whether these tools can predict event-free (EFS) and disease-free survival (DFS) in patients treated with neoadjuvant and/or adjuvant trastuzumab-based therapies.
NCT00725946
This is a pilot imaging study for women whose tumors express NIS \[Na+I- symporter, sodium iodide symporter\]. Eligibility is limited to the presence of strong (3+) and/or plasma membrane staining in \> 20% of cells as determined by immunohistochemical methods. A total of 10 patients will be imaged with 124I PET/CT (serial scans over 24 hour period) to determine radioiodide uptake and distribution in tumor tissue. Thyroid iodide uptake and retention will be blocked beginning one week prior to 124I PET/CT scan with thyroid hormone (T3) and methimazole (impedes organification). Tumor, organ and whole body dosimetry will be calculated in each patient.
