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.
NCT06362616
This study evaluates the acute toxicity and feasibility of repeat breast conserving therapy with preoperative accelerated partial breast re-irradiation (PAPBI) in female patients aged 51 years or older with ipsilateral recurrent or second primary low-risk breast cancer or DCIS.
NCT07353437
The study is a randomized, open-label, multicenter phase II clinical trial of the efficacy and safety of fluzopanib in the adjuvant treatment of early breast cancer using germline mutations in homologous recombination repair pathway genes. Study design Patients will be randomized into 2 groups in a 1:1 ratio after enrollment: Experimental group: fluzoparib, specific: fluzoparib 100 mg bid for 1 year. As well as the standard of care selected by the physician (in case of TNBC, combination therapy includes but is not limited to immunotherapy or capecitabine; in case of HR +, combination therapy includes but is not limited to endocrine therapy or CDK4/6 inhibitors). Control group: Doctors' choice of standard treatment (in case of TNBC, combination therapy includes but is not limited to immunotherapy or capecitabine; in case of HR +, combination therapy includes but is not limited to endocrine therapy or CDK4/6 inhibitors)
NCT05633979
To find a recommended dose of valemetostat that can be given in combination with trastuzumab deruxtecan to patients with low/ultra-low HER2-expressing metastatic breast cancer.
NCT04568616
This is a single-arm, open-label study testing the effects of neoadjuvant therapy with the aromatase inhibitor letrozole in post-menopausal women with Stage I-III ER+, HER2- breast cancer. Eligible subjects will be treated with letrozole therapy for 4 to 24 weeks prior to surgical resection of the tumor. Tumor specimens obtained at baseline (diagnostic biopsy) and at surgery (surgical specimen) will be compared using molecular analyses. A subset of subjects will be asked to provide an optional research tumor biopsy prior to treatment for molecular analysis. Subjects will be evaluated for treatment adherence and provide feedback via survey questionnaires to identify potential causes of non-adherence.
NCT07116161
The purpose of this research study is to investigate the acceptability, feasibility, and effectiveness of exercise therapy and cognitive behavioral therapy (CBT) in improving fatigue levels and breast cancer treatment adherence in breast cancer patients.
NCT02668666

NCT06401421
The EXActDNA-003 study will prospectively enroll participants who are planning to undergo chemotherapy for high-risk, early breast cancer, who are willing to provide tissue and blood specimens for circulating tumor DNA (ctDNA) analysis. Participants will be followed for up to 5.5 years.
NCT02086578
The purpose of this study is to determine if a radiation treatment called "Multi-beam Intensity Modulated Radiation Therapy"(IMRT) can reduce side effects related to your implant if they are a candidate for radiation therapy. Currently, the standard method of giving radiation is with "3D radiation", which only uses 2-5 beams of radiation. "Multi-beam" IMRT works by using 8-12 small radiation beams to give a more "tailored" or "customized" radiation dose to the implant, breast, chest wall and lymph nodes. At the same time, multi-beam IMRT may lower the radiation dose to the heart, lung and nearby tissues. The goal of the study is to reduce complications after irradiation to the implants. The study doctors have recently completed a trial using this technique and are now specifically looking at its impact on women with implant reconstructions who are undergoing post-mastectomy radiation therapy. By delivering a more "customized" dose of radiation to the implant, the intent is to reduce side effects of radiation on the implant.
NCT05633654
The goal of this study is to find out if the experimental product, sacituzumab govitecan-hziy (SG) in combination with pembrolizumab given after surgery, is effective and safe compared to the treatment of physician's choice (TPC) which includes either pembrolizumab or pembrolizumab plus capecitabine in participants with triple negative breast cancer that still remains after surgery and pre-surgical treatment.
NCT07350928
This clinical trial aims to evaluate the efficacy and safety of Dexmedetomidine Hydrochloride Nasal Spray for conscious sedation and anxiety relief during breast-conserving surgery. The main questions it aims to answer are: Does Dexmedetomidine Hydrochloride Nasal Spray effectively provide intraoperative sedation and improve postoperative awakening time? What changes in vital signs or postoperative complications do participants experience when using this medication? Researchers will compare Dexmedetomidine Hydrochloride Nasal Spray to a placebo (saline nasal spray) to determine its efficacy in breast-conserving surgery. Participants will: Receive preoperative administration of either Dexmedetomidine Hydrochloride Nasal Spray or the placebo nasal spray; Undergo regular intraoperative and postoperative assessments, including sedation scores, awakening time, and pain scores; Provide satisfaction feedback and be monitored for changes in vital signs and complications.
NCT07352137
The goal of this clinical study is to evaluate the effectiveness and safety of a novel breast reconstruction technique combining endoscopic nipple-sparing mastectomy (E-NSM) with immediate multistage fat grafting (IMFG) in female patients aged 18 years or older with clinical stage 0 to II breast cancer who desire immediate breast reconstruction. The main questions it aims to answer are: Does the combined E-NSM and IMFG approach improve patient-reported outcomes, including satisfaction with breasts and physical well-being, as measured by the BREAST-Q questionnaire? What is the frequency and nature of surgical complications associated with this technique, such as wound healing, hemorrhage, and need for reoperation? Participants will undergo endoscopic nipple-sparing mastectomy with lymph node surgery followed by immediate multistage fat grafting for total breast reconstruction via a small cosmetic axillary incision. They will also complete the BREAST-Q questionnaire and receive clinical and photography-based assessments at follow-up visits to evaluate aesthetic and quality-of-life outcomes.
NCT07313033
Invasive squamous cell carcinoma (ISCC) represents 5 to 15% of breast cancers. Despite the rarity of this pathology, the number of patients with Invasive squamous cell carcinoma treated at HCL is significant. Patients at risk of metastasis are usually referred to the HCL Nuclear Medicine departments to perform positron emission tomography - computed tomography (PET/CT) with \[18\]F-FDG as an extension assessment. The investigators know that \[18\]F-FDG PET/CT has limited diagnostic performance for assessing the extent of breast cancer with a sensitivity of 66-96% for all histologies combined. For the ISCC, these performances are even lower with average Standard Uptake Value (SUV) values of 3.4 \[2.8-3.9\] versus 6.6 \[4.8-9.7\] for the others histological types of breast cancer. False negatives in \[18\]F-FDG PET/CT are due to an insufficient osteoblastic and immune response in the tumor stroma. Avril \& al. showed 65.2% false negatives with \[18\]F-FDG PET/CT for ISCC. This is why the search for new imaging techniques in this indication is particularly relevant. Targeting fibroblast activation protein (FAP), a type II membrane glycoprotein belonging to the dipeptidyl peptidase-4 family, is a promising strategy for imaging tumor stroma, particularly in epithelial carcinomas . The investigators would like to compare the \[18\]F-FDG PET/CT technique currently used to this new emerging modality. The investigators hypothesize superior diagnostic performance of \[68\]Ga-FAPI PET/CT compared to \[18\]F-FDG PET/CT for the assessment of ISCC extension, with a gold standard histological. The investigators translate this into the hypothesis of finding 30% of positive FAPI PET when the \[18F\]FDG PET/CT is negative or doubtful. The advantage of this project and this new imaging modality is to not undertreat patients wrongly classified as non-metastatic. The investigators therefore wish to offer \[68\]Ga-FAPI PET/CT to patients with negative \[18\]F-FDG PET/CT. The FAPICL project constitutes a seed project before a larger structuring study.
NCT04319510
Craniosacral Therapy (CST) is a non-manipulative, very gentle, manual treatment method that aims to release restrictions of the fasciae and regulate the arousal of the sympathetic nervous system, which is often increased in chronically ill patients. Initial randomized trials support CST's efficacy and effectiveness in reducing symptoms of patients with psychosomatic and chronic pain disorders. To date, there is no trial investigating the effectiveness of CST as a supportive strategy for enhancing cancer-related quality of life in women with breast cancer. In clinical practice, therapists also report alleviating as well as regulating effects of simple CST self-help techniques, offered to patients within a group concept. Within the recent study, a CST treatment and self-help protocol for women after curative therapy of breast cancer was developed and shall be tested against a waiting list control group. The first group will receive 24 units of CST treatment in a 1:1 setting with a certified craniosacral therapist over 12 weeks. The second group will receive 24 units of group training in CST self-help techniques offered by a certified craniosacral therapist over 12 weeks. They will be reassessed after 12 and 26 weeks (6 months) after randomization. The third group will wait for 26 weeks and will receive no specific study intervention. After 26 weeks patients of the third group were offered self-selection to either individual CST or CST self-help group training. For all groups, treatment as usual is allowed.
NCT04443413
This phase III trial compares the rate of complications of x-ray therapy versus proton beam radiation therapy after breast conserving surgery or mastectomy in treating patients with breast cancer. X-ray therapy is a form of radiation therapy that uses high-energy radiation from x-rays to kill tumor cells and shrink tumors. Proton beam radiation therapy is a type of radiation therapy that uses high-energy beams to treat tumors. It is not yet known what level of complications x-ray therapy or proton beam radiation therapy have in treating patients with breast cancer.
NCT04964934
The study is intended to show superiority of AZD9833 in combination with CDK4/6 inhibitor (palbociclib, abemaciclib or ribociclib) versus aromatase inhibitors (anastrozole or letrozole) in combination with CDK4/6 inhibitor in patients with hormone receptor-positive (HR-positive), human epidermal growth factor receptor 2-negative (HER2-negative) metastatic breast cancer with detectable ESR1 mutation.

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.
