NCT04713917
Many studies have shown that locoregional treatment (surgery, radiotherapy) and systemic treatment (endocrine therapy and chemotherapy) for breast cancer (BC) may impact sexuality by causing physical and/or psychological damages. Approximately 50-75 % of BC survivors suffer from vulvovaginal atrophy (VVA). The earliest symptoms of VVA are decreased vaginal lubrication, followed by other vaginal and urinary symptoms, such as burning, itching, bleeding, leucorrhoea, dyspareunia and dysuria symptoms. Various surveys have shown that VVA symptoms lead to female sexual disorder and on their partners through sexual unsatisfactory. However, it appears that sexuality is a little discussed topic during the follow-up of BC survivors. Most of patients relate a poor satisfaction with information and counselling related to sexuality and vaginal health, which are denied by many practitioners. Patients treated for BC cannot find relief in hormonal replacement therapy (HRT), which is considered the gold standard treatment for VVA symptoms. The usual treatments for these women are topics such as ovula or gel (lubricant, hyaluronic acid (HA)…) with however, a short term effect even when these topics are applied regularly and correctly during at least 2 to 3/weeks.In the literature, there is a significant impact on VVA at one month but later data are lacking . Moreover, patients' compliance and daily application are paramount of importance for efficacy that could disappear when the treatment is stopped. No randomized controlled trial has compared this treatment to innovative strategies. In this context, it is important to establish management strategies for VVA and sexual disorder after BC. Our objective is to assess prevalence rate of VVA among breast cancer survivors after the loco regional treatment and chemotherapy, and to compare the efficacy of innovative treatments namely, new biophysical inductor (Laser CO2) and chemical bio inductor (Hyaluronic acid injections) treatments to the efficacy of standard non-hormonal topic treatment for improving the VVA and the quality of sexual life on a long-term.
NCT05218876
(Neo-)adjuvant chemotherapy for breast cancer has deleterious effects on muscle tissue resulting in reduced skeletal muscle mass, muscle function, and cardiorespiratory fitness. Various exercise regimens during cancer treatment have been shown to counteract some of these side effects. However, no study has compared the effect of high intensity training vs. low-to moderate intensity training on muscle tissue cellular outcomes and function in breast cancer patients during chemotherapy. The present study aims to compare the effects of high vs. low-to moderate intensity training on its ability to counteract deleterious effects of chemotherapy on skeletal muscle in women diagnosed with breast cancer. Eighty newly diagnosed women with breast cancer planned to start (neo-)adjuvant chemotherapy will be randomized to either a group performing a combination of strength and endurance training with high intensity or a group performing training with low to moderate intensity. Muscle biopsies from m. vastus lateralis for assessment of muscular cellular outcomes will be collected and muscle function and cardiorespiratory fitness will be measured before the first cycle of chemotherapy (or, when not possible, one week after) (T0), halfway through chemotherapy (T1), and after completion of chemotherapy (T2). It is estimated that approximately 50% will be willing to take muscle biopsies. The study will give important information about the effects of different training intensities for breast cancer patients during treatment and will contribute with knowledge about how to refine exercise programs that are effective and compatible with multidisciplinary management of breast cancer.

To study the safety and tolerability of the drug 99mTc- RM26 after a single injection in a diagnostic dosage. The secondary objective are: 1\. To compare the obtained 99mTc- RM26 SPECT imaging results with the data of CT and/or MRI and/or ultrasound examination and immunohistochemical (IHC) studies in prostate cancer and breast cancer patients.
NCT00474604
RATIONALE: Diagnostic procedures, such as MRI, may help diagnose breast cancer. It may also help doctors predict a patient's response to treatment. PURPOSE: This clinical trial is studying breast MRI in women with known or suspected breast cancer and in healthy participants.
NCT01142401
This randomized phase II trial studies how well fulvestrant works with or without bortezomib in treating patients with estrogen receptor positive breast cancer that has spread to other places in the body and cannot be removed by surgery. Estrogen can cause the growth of breast cancer cells. Hormone therapy using fulvestrant may fight breast cancer by lowering the amount of estrogen the body makes. Bortezomib may stop the growth of breast cancer cells by blocking some of the enzymes needed for cell growth or by blocking blood flow to the tumor. It is not yet known whether fulvestrant is more effective with or without bortezomib in treating breast cancer.
NCT04468113
Neoadjuvant systemic therapy (NST) is increasingly recommended for patients with early breast cancer, and the rate of patients with pathological complete remission (pCR) is increasing due to the use of modern chemotherapy regimens and targeted therapies, especially in patients with human epidermal growth factor receptor 2 positive (HER2+) breast cancer and triple negative breast cancer (TNBC). It is therefore important to mark a lesion (with e.g. clip) before the start of NST in order to safely identify and localize a clip and (former) tumor bed after completion of NST. Reliable sonographic detection of the clip would be preferred to mammography-guided detection and marking. In addition to avoiding radiation exposure by mammography and reducing time, personnel and financial expenditure, ultrasound-guided wire marking of the clip is less painful for the patient than stereotactic wire marking. The present prospective registry study aims to evaluate how often the intramammary Tumark® Vision clip can be detected by ultrasound after completion of NST in patients with TNBC and HER2+ breast cancer and thus, in the case of pCR, how often the elaborate clipping with mammographic (stereotactic) guidance can be avoided.
NCT02672475
This phase I trial studies the side effects and best dose of Galunisertib when given together with paclitaxel in treating patients with androgen receptor negative or triple negative breast cancer that has spread to other places in the body. Some tumors need growth factors, which are made by the body's white blood cells, to keep growing. Galunisertib may interfere with growth factors and help cause tumor cells to die. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving Galunisertib together with paclitaxel may kill more tumor cells.
NCT06133959
The goal of this two-phase project is to adapt The-Optimal-Lymph-Flow (TOLF) behavioral intervention to be culturally appropriate, and subsequently test the intervention in Black and Hispanic patients. The investigators have developed and tested behavioral intervention program TOLF that builds patients' self-management skills to promote lymph flow and results in complete pain reduction, reduced lymph fluid level, reversed mild lymphedema, and improved quality of life (QOL). Of concern, this promising intervention has not been adapted to reduce patient barriers (e.g., relevance, cost, time, travel, competing demands) and system barriers (e.g., intervention availability, staffing, therapist) to timely interventions faced by Black and Hispanic women. Specific aims are to: Aim 1: Engage Black and Hispanic women (N=24) in adapting TOLF to be highly culturally appropriate. The investigators will conduct focus groups to refine TOLF focusing on barriers faced by and preferences of Black and Hispanic women. Aim 2: Conduct a pilot randomized controlled trial (RCT) (N=60) equally allocating women to either 1) TOLF or 2) lymphedema education (e-Lymph) to examine feasibility, acceptability, and examine primary outcomes (lymphatic pain, pain severity and interference, and lymph fluid level) and secondary outcomes (daily living function, psychological distress, QOL, self-efficacy for pain management) of the culturally appropriate behavioral interventions.
NCT02915445
This study is for patients that have nasopharyngeal carcinoma, breast cancer, gastric cancer and other solid tumors. As epithelial cell adhesion molecule (EpCAM) is a well characterized molecule that is closely with poor prognosis and tumor metastasis and invasion. Many therapies targeting EpCAM have shown benefits for cancer patients. This study is to determine the safety of the engineered T cells armed with chimeric antigen receptor (CAR-T) recognizing EpCAM. At the same time, efficacy is to be evaluated by the criteria of RECIST. The EpCAM CAR-T were produced by lentiviral transduction of the novel 2nd generation of CAR genes. Different cohorts of patients receive EpCAM CAR-T with a dose-escalating manner. This study is to find the largest dose of EpCAM CAR-T, to learn what the adverse effects are and to find out whether this experimental intervention might help patients with nasopharyngeal carcinoma, breast cancer and other EpCAM positive solid tumors.
NCT06144346
This is a phase III randomized study evaluating the benefit from adding metastases directed therapy and locoregional treatment of the primary in breast cancer patients diagnosed with de novo oligometastatic disease patients will be randomized to receive the standard of care (SOC) treatment vs. systemic treatment + Stereotactic Ablative Radiation Therapy. Responders will be randomized to either undergo loco-regional management of the primary tumor or not
NCT06134570
ALDH1A1 isozyme oxidizes Retinaldehyde to retinoic acid, which regulates the expression of the genes involved in tumor-initiating stem-like cells, thereby initiating tumor growth and resistance to drugs. Much emphasis has been focused on ALDH1A1 as a CSC marker. High expression of ALDH1A1 has been reported as a poor prognostic marker in several tumor types and is associated with poor patient outcomes .
NCT04734262
The purpose of this study is to assess the efficacy and safety of sitravatinib plus tislelizumab or combination with nab-paclitaxel in locally recurrent or metastatic triple-negative breast cancer (TNBC) patients.
NCT01931709
This clinical trial studies fludeoxyglucose F 18 (FDG) positron emission tomography (PET) and dynamic contrast-enhanced (DCE)-magnetic resonance imaging (MRI) in predicting response to treatment in patients with breast cancer. Comparing results of diagnostic procedures done before, during, and after chemotherapy may help doctors predict a patient's response to treatment and help plan the best treatment.
NCT06093022
The liver represents the third most common site of breast cancer (BC) metastases behind the lymphatics and bone. The primary treatment for BCLM remains chemo-therapy and, more recently, targeted immunotherapy. The role of liver resection in BCLM remains controversial. The primary aim of the study is to compare the efficacy of liver resection vs. medical therapy alone in Breast Cancer Liver Metastasis (BCLM) patients.
NCT06130111
Rationale:To improve the definition of the target volume for radiotherapy of the chestwall after different types of mastectomy, the exact localization of regions at risk for a local recurrence should be known. However, there are currently insufficient data in literature showing where local recurrences occur after different types of mastectomy. Objective: The primary objective of the proposed study is to determine whether the spatial, location of a breast cancer recurrence after mastectomy, differs for different types of mastectomy. Study design: Retrospective study evaluating spatial location and site of recurrences after mastectomy. Study population: The investigators aim to include all breast cancer patients treated with mastectomy in the Netherlands between 2003- 2008, and known to have experienced a local recurrence as the first site of failure. Primary endpoint: Spatial location of local recurrence (e.g., primary tumour bed, scar, skin, subcutaneous, nipple, areola, pectoral muscles).
NCT03180086
In a randomized controlled trial, the investigators will test the effect of a novel strategy for breast cancer risk assessment and risk-based management of women in their 40s seen in primary care. The investigators anticipate that this approach will lead to more optimal use of mammography screening and breast cancer prevention interventions in women in their 40s and as a result will improve care of these women.
NCT04767464
The Compass Course (CC) is a group intervention designed for individuals with Breast Cancer. Over the course of 8 face-to-face group sessions, the CC is designed to help participants reclaim a sense of self-grounded purpose in daily life, defined as intentional use of time and energy in ways that align with one's values, strengths, and sources of personal meaning (e.g., inner compass) in the moments that compose a day. Because of COVID-19, in-person groups are discouraged and so we need to identify new ways to provide group-based interventions that are feasible and efficacious.
NCT05453604
The aim of this study is to evaluate and optimize protocols for the isolation and analysis of analytes in urine (cell-free nucleic acids, extracellular vesicles and proteins). The following factors will be evaluated (1) volumetric collection with Colli-Pee®, a collection device developed by Novosanis for standardized collection of urine, and (2) stabilization methods. This is a prospective study in which urine samples will be collected from healthy volunteers, urine samples and a blood sample from pregnant women and cancer patients with solid tumors with emphasis on breast- and prostate cancer. The participants will be asked to provide a urine sample collected with the Colli-Pee® device and fill out an online questionnaire to collect usability data. Thereafter, the urine sample will be aliquoted to be used in different pilot studies for the protocol optimization. For the pilot study where the effect of volume will be assessed, participants will be requested to collect multiple samples with different Colli-Pee® variants and fill out questionnaires accordingly.
NCT03054363
This is a multicenter run-in phase Ib / roll-over phase II study of triple targeted drug combination (HER2-targeted small molecule inhibitor tucatinib, CDK4/6 inhibitor palbociclib and aromatase inhibitor letrozole) as a first or second line of therapy in patients with metastatic hormone receptor positive and HER2-positive breast cancer.
NCT05700019
The primary objective of this study is to examine how exposure to "pinkwashed" alcohol advertisements (i.e., ads that associate the company with breast cancer awareness or charities) affects consumers' perceptions that alcohol increases the risk of breast cancer. The investigators will randomize participants to view 3 'pinkwashed' social media advertisements for alcohol or 3 control advertisements for alcohol (i.e., 'de-pinked' standard alcohol advertisements that match the intervention advertisements on overall design but do not mention breast cancer). Each participant will view the 3 advertisements for their arm (presented in random order) and respond to survey questions programmed in Qualtrics.
