Study is enrolling newly diagnosed breast cancer patients about to start chemotherapy and age-matched control participants. The investigator is trying to better understand the prevalence of cognitive difficulties in cancer patients receiving chemotherapy compared to the general population as well as what biological mechanisms may play a role in the development of these difficulties. Patients will be asked to complete six assessments over the course of approximately 5 months. Assessments 1,3, 4.5 and 5 include computerized and paper and pencil cognitive testing as well as blood draws. Assessments 2 and 4 only involve the collection of a blood sample. An optional sub study is offered after Assessment 1. It involves a research brain MRI at Assessment 4.5 and cognitive testing and another research brain MRI at Assessment 6.
NCT07547423
The goal of this clinical trial is to learn if auricular laser acupuncture can improve sleep quality and alleviate related symptoms in female breast cancer patients aged 18 to 75 with insomnia. The main questions it aims to answer are: 1. Does active auricular laser acupuncture improve sleep quality and reduce the severity of insomnia? 2. Does it help lower levels of cancer-related fatigue, anxiety, and depression? Researchers will compare an active auricular laser acupuncture group to a sham control group (receiving no therapeutic laser energy) to see if active laser acupuncture is effective for symptom relief. Participants will: 1. Receive 10 sessions of laser treatment (active or sham) twice a week for 5 weeks, while wearing protective goggles to ensure blinding. 2. Wear an actigraphy wristband and keep a sleep diary to monitor sleep patterns, and undergo heart rate variability (HRV) measurements at baseline and Week 5 (post-treatment). 3. Complete questionnaires assessing sleep, fatigue, mood, and quality of life at baseline, Week 5 (post-treatment), and Week 10 (follow-up).
NCT07378319
The goal of this clinical trial (prospective case series) is to evaluate the feasibility, safety, and preliminary clinical outcomes of ultrasound-guided dextrose prolotherapy in female breast cancer survivors with persistent ipsilateral chest wall and axillary pain and tightness who have plateaued with standard physical therapy. The main questions it aims to answer are: Does ultrasound-guided dextrose prolotherapy significantly improve upper extremity functional limitation (measured by the QuickDASH questionnaire)? What are the effects of this intervention on pain intensity (NRS), active shoulder range of motion (AROM), and anterior chest wall soft-tissue tightness (pectoralis minor muscle length)? Participants will: Undergo a comprehensive baseline physical examination and ultrasound assessment of the symptomatic chest wall and axilla. Receive three sessions of ultrasound-guided 5% dextrose injections into targeted soft-tissue planes at 4-week intervals. Continue their designated standard rehabilitation program, including range-of-motion and stretching exercises. Attend follow-up assessments at 4-week intervals during the treatment phase, with long-term follow-up at 3 and 6 months after the final injection to evaluate the durability of the response.
NCT07367074
This study aims to evaluate the effect of an educational intervention on sexual function and therapeutic adherence among women with breast cancer followed in the medical oncology department of Ibn Tofail Hospital, affiliated with Mohammed VI University Hospital Center in Marrakech. Participants will receive a structured therapeutic education program focusing on breast cancer, available treatments and their potential side effects, as well as treatment adherence and its prognostic significance. Educational sessions will be complemented by patient follow-up to reinforce key messages and support adherence. The study will assess changes in sexual function and therapeutic adherence before and after the educational intervention.
NCT06062992
Contrast-enhanced mammography (CEM) is an emerging breast imaging modality that is based on dual-energy mammography and the injection of iodinated contrast agent. A typical CEM study consists of a low-energy image (equal to a FFDM image) and a recombined image (in which areas of contrast enhancement can be appreciated). However, the situation can occur that lesions are visible only on the recombined (contrast) images (in this protocol defined as 'recombined-only lesions' or ROLs). In these cases, radiologists need to perform 'contrast-enhanced stereotactic biopsy' (CESB), in which CEM is used as a targeting modality. However, experiences with CESB are still limited and one of the most urgent questions that need to be answered is the amount of tissue sampling that is required to reach a final diagnosis. The investigators aim to study where the cut off will be in terms of tissue sampling volume needed (i.e., number of biopsies) for a reliable diagnosis.
NCT07434817
Approximately 200 English- or Spanish-speaking women newly diagnosed with stage I-III breast cancer will be randomized to either receive access to an online sexual health video series or receive usual care. Participants will complete surveys at baseline and every two months for six months, measuring self-efficacy in patient-provider communication and perceived barriers to discussing sexual health. Electronic health record review will assess utilization of sexual-health-related medical and supportive services. A subset of participants will participate in qualitative interviews to explore their sexual health experiences during treatment and, for those receiving the intervention, the perceived impact of the videos.
NCT04343820
Breast implants associated with the installation of a complementary matrix (of dermal or synthetic origin), showed satisfactory results in term of post-operative follow-up but also aesthetic outcomes. The objective of the subcutaneous positioning of this implant, is to reduce the muscular pain related to the stretching of the muscular muscle, the deformations related to the muscular contraction with an animation of the prothesis, but also the risk of hull when associated with a matrix. It also pursues the objective, of obtaining a better aesthetic result, by systematically coupling at least one lipo-modelling session. For a long time, patients with a history of mastectomy and radiotherapy benefited from secondary breast flap reconstruction, in order to reduce the risk of complications and achieve a satisfying aesthetic outcome. But the lipo-filling technique allowed to reconsider the management of these patients. The benefits of fat tissue transplants are know to improve tissue trophicity (flexibility, thickness, vascularization). The objective of this study, is to evaluate the feasibility of secondary breast reconstructions by prepectoral positioned implant after lipo-preparation of the wall.
NCT06552091
Patients treated for breast cancer with hormone therapy (HT) suffer from hot flashes. This side effect impacts treatment adherence. Indeed, approximately 50% of women take less than 80% of the prescribed dose, and up to 50% abandon their treatment before the fifth year of prescription, significantly increasing the risk of recurrence. Moreover, these hot flashes strongly impact the quality of life. According to the CANTO study, these hot flashes can persist up to two years after diagnosis, affecting social relationships, return to work, and physical and mental health. Some side effects resulting from HT (sleep disturbances, fatigue, hot flashes) could be alleviated by a non-pharmacological approach involving the patient. Our hypothesis is that a non-pharmacological solution, such as the use of self-hypnosis, could reduce hot flashes and the side effects related to HT or the perception thereof in patients treated for breast cancer. Consequently, this could improve the quality of life and lead to better treatment adherence. The principal objective is to evaluate the effect of daily guided self-hypnosis sessions in reducing hot flashes in patients with non-metastatic breast cancer receiving anti-aromatase hormone therapy. The secondary objectives are to evaluate : * Patient adherence to guided self-hypnosis via a digital solution * Quality of life * Sleep quality * Satisfaction with care * Usability of the digital tool The originality of this clinical trial is the proposal of self-hypnosis sessions over three weeks with three different themes using a digital solution.
NCT05527769
This is a prospective, single-center, non-randomized study of immediate breast reconstruction (IBR) using a pre- or retro-pectoral technique in patients with breast cancer who have undergone total mastectomy. The technique used is chosen according to the characteristics of the breast, the morphology of the patient and her wishes after informed information on the different techniques. The aim is not to compare the two techniques but rather to evaluate the early functional results of these two methods in order to better understand them and to propose a management adapted to each. The main objective will be to evaluate the postoperative pain by BPI questionnaire. The investigators also wish to observe the functional results of the homolateral upper limb by DASH questionnaire, the quality of life by BREAST Q questionnaire and the occurrence of complications.
NCT07006662
The aim of this 6-month proof-of-concept study is to map out the chest wall perforators in relation to anatomical landmarks for partial breast reconstruction.
NCT07407517
This study enrolled patients with early-stage triple-negative breast cancer who had undergone radical surgery. The postoperative pathology met the TNM staging criteria of pT1c-3N0-3M0, and immunohistochemistry (IHC) results confirmed ER-negative status (IHC showed \<1% of tumor cells positive for ER), PR-negative status (IHC showed \<1% of tumor cells positive for PR), and HER2-negative status (IHC intensity of 0 or 1+; or IHC intensity of 2+ but with negative in situ hybridization results). Additionally, patients either exhibited high AR expression (IHC showing AR ≥10%) or were classified as the LAR subtype based on digital pathology. This study plans to prospectively enroll 904 subjects, who will be randomized in a 1:1 ratio after completing standard chemotherapy. They will be allocated to either the standard-of-care (SOC) chemotherapy followed by everolimus group or the SOC-alone group. The study aims to evaluate the efficacy of SOC chemotherapy followed by everolimus versus SOC chemotherapy alone as adjuvant therapy for patients with early-stage radically resected triple-negative breast cancer of the LAR subtype, with the primary endpoint being 3-year invasive disease-free survival (iDFS).

The Pecs block (pectoral nerves block) is an easy and reliable superficial block inspired by the infraclavicular block approach and the intercostal abdominis plane blocks . Many additives were used in combination with local anesthetics in Pecs block to prolong the postoperative analgesia (fentanyl, dexmedetomidine).
NCT03881085
Despite increased access to early detection and the availability of more effective therapeutic strategies, African American women continue to experience excess rates of morbidity and mortality from breast cancer. An emerging hypothesis about breast cancer disparities is that social conditions and physiological responses to social stressors influence biological processes that are important to the initiation and progression of disease. This hypothesis is based on data from animal studies which have shown that rats that are exposed to social stressors such as isolation are likely to develop mammary tumors that are histologically and etiologically similar to those that develop among African American women. The HPA axis plays a central role in regulating the physiological stress response; dysregulation of the HPA has been suggested as a mechanism through which social and biological factors contribute to racial disparities in breast cancer outcomes. Many African Americans experience stressful life events and circumstances, including economic, discriminatory, and other stressors. These social factors may contribute to an increased risk of advanced stage disease, but not all African American women who are exposed to adverse social factors develop advanced stage disease and those who have a limited number of psychosocial stressors can develop advanced stage breast cancer, regardless of early detection. This may be because stress reactivity, or one's physiological and psychological responses to a stressor, is highly individualized and dependent on psychological and social determinants as well as genetic factors. But, these biological and psychosocial pathways have not been examined among women at increased risk for disparities. Therefore, this study will characterize stress reactivity and emotional regulation among African American breast cancer survivors and measure the association between these responses and decisions about cancer control and treatment compliance. As part of providing empirical data on biological and psychological pathways that contribute to breast cancer disparities, the investigator's study will identify novel intervention targets that can be used to improve self-management in a population that is at risk for limited cancer control.
NCT06483997
This prospective, observational cohort study will evaluate the extent of associations between self-reported pro- or anti- inflammatory dietary intake patterns for one month before induction chemotherapy for gynecological cancer or neo/adjuvant chemotherapy for breast cancer and baseline serum hepcidin concentrations. Associations between hepcidin concentration and relative dose intensity (RDI) of chemotherapy will also be evaluated.

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.
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.
NCT05721326
The goal of this sequential study design is to increase genetic testing in those meeting national clinical guidelines. The main question it aims to answer is: which intervention is most effective in uptake of genetic testing for the target population? Participants will receive genetic testing and counseling that may initiate life-saving screenings.
NCT05873296
The sedentary lifestyle in women with breast cancer generates a problem for public health. An alternative that has been used to reduce sedentary behavior are interventions with the use of information technology, as well as projects with health education can cause lifestyle changes. However, little is known about the effect of these interventions on self-awareness and self-care in women with breast cancer. This aim of study is evaluate the effect of health education on sedentary behavior, lifestyle, physical activity level, nutrition, self-esteem, anxiety and depression, quality of life, pain, functional capacity, and strength in women with breast cancer. This is a study the 12 weeks, with patients being treated for breast cancer, distributed for two groups: Group Health Education Recommendations and Control Group.
