NCT05331807
Breast cancer (BC) is the most common malignant disease, which is fifth leading cause of cancer mortality worldwide. Poor nutritional status is one of the common physical symptoms found among cancer patients, in which it is caused by both cancer disease state and its oncology treatment regimens used. Cancer patients develop a tumor-associated malnutrition characterized by an insufficient supply of macro- and micronutrients and systemic chemotherapy treatment that could significantly affecting the nutritional status of these patients by its side effects associated with chemotherapy that may lead to many medical complications that often requires hospitalization and death. An adequate nutritional intervention can have a beneficial impact on the disease condition and also the progress of the disease, as an integral part of adjuvant therapy on cancer care. Numerous studies had shown that the use of EPA and DHA are safe (absence of cardiotoxic effects) and effective in reducing the common chemotherapy-related side effects, such as bone density loss, peripheral neuropathy and weight gain. The question remains arises to whether administration of both vitamin D and omega-3 fatty acids supplementations could be used as important nutritional strategy during the active oncology treatment in breast cancer patients. In Palestine, nutritional intervention strategies are poorly evaluated in the oncology setting especially among patients undergoing chemotherapy. Suitable and proper nutritional interventions among breast cancer patients during active oncology treatments could help to improve nutritional status, decrease mortality and improve quality of life among these subjects. Hence, the present study is formulated to assess the effect of combined omega-3 fatty acid and vitamin D supplementation on the nutritional status, quality of life and blood inflammatory markers among breast cancer women undergoing chemotherapy treatment in the Gaza Strip, Palestine.
NCT06404697
cN3c breast cancer with ipsilateral supraclavicular (SCV) lymph nodal (SCLN) metastasis is known to have a dismal prognosis. Currently, the combined-modality therapy consisting of primary systemic therapy (PST), subsequent local and/or systemic therapy based on response is the standard of care. However, the value of giving radiotherapy (RT) boost to SCV region remains uncertain in cN3c patients. This study aimed to assess the efficacy and safety of RT boost to the SCV area in high-risk cN3c breast cancer patients based on nodal response following PST.
NCT05420779
This research study is evaluating the efficacy and safety of TSL-1502 capsules in patients with breast cancer, will be included HER2-negative locally advanced or metastatic breast cancer patients with germline BRCA mutations.
NCT06403904
The Modena hereditary breast cancer group identified 3498 BRCA test candidates affected by breast cancer (BC). Among those, 392 were BRCA1/2 positive (11.2%). Since 2018, the site started to analyze eligible BC patients by multi gene panel (MGP) test. Fifty hundred sixty BRCA negative patients have been recalled, whereas other 934 were firstly analyzed by MGP. Totally, among 1494 BC patients analyzed by MGP test, 33 were PALB2 mutation carriers (2%). By involving the Italian Society of Genetic Oncology and 11 European Institutions, it is calculated to identify about 300 PALB2 mutation carriers. PALB2 is a breast cancer susceptibility gene that encodes the BRCA2- interacting protein. Mono-allelic mutations of PALB2 are associated with an increased risk for breast and ovarian cancer in women, prostate cancer in men, and pancreatic cancer in both gender. Women with no family history of breast cancer have a cumulative risk of 33%, compared to 58% in women with two or more family members with breast cancer. Several studies with populations ranging from to 54 to 362 individuals aimed to describe breast cancer phenotypic characteristics in PALB2 mutation carriers. Some of these studies suggested an association with triple-negative phenotype, older age at diagnosis (\>30 years), tumor size \> 2 cm, negative HER2 status, lymph nodes positive and bilaterality. Nevertheless, results among different studies are contradictory and no data on prognosis of these patients are reported. Furthermore, the clinical potential of PARP inhibition beyond currently approved indications to additional patients whose tumors have (epi)genetic changes affecting homologous recombination repair raises new interest in PALB2 mutations as molecular target. Primary objectives is to study the incidence and mortality rates of gPALB2 Breast Cancer.
NCT04129216
The investigators would like to study the genetic and molecular outcomes that results after a short term neoadjuvant hormonal therapy on patients with breast cancer.
NCT02850939
Adjuvant endocrine hormonal therapy (EHT) is highly effective and appropriate for nearly all breast cancer patients with hormone receptor-positive tumors, which represent 75% of all breast cancer diagnoses. Long-term use of EHT reduces cancer recurrence rates and cuts the risk of death nearly in half during the second decade after diagnosis, research shows. Despite the proven benefits, about 33% of women who are prescribed EHT do not take their medication as prescribed (less than 80% take their daily dosage) and are thus at higher risk of recurrence and death. This educational randomized controlled study will develop and pilot-test a bilingual, culturally tailored, personalized, interactive mobile application (app) in combination with patient navigation to promote and improve adherence to endocrine hormonal therapy (EHT) among breast cancer patients.
NCT04437602
Patients diagnosed with breast cancer after routine assessment with digital mammography and ultrasound and scheduled for primary surgery are included in the trial. The patients are randomized 1:1 to go through additional contrast enhanced mammography (CEM) or no further imaging preoperatively. Primary endpoint is rate of patients with change of treatment: a) mastectomy instead of partial mastectomy due larger unifocal or multifocal extent, b) partial mastectomy instead of mastectomy due to improved demarcation of the tumour area, c) bilateral surgery instead of unilateral due to findings of contralateral cancer, d) neoadjuvant therapy instead of primary surgery due to more advanced disease. Rate of reoperation and rate of avoidable mastectomies are secondary endpoints.

Hormone receptor-negative tumors are estrogen receptor-negative (ER-negative) and progesterone receptor-negative (PR-negative). These tumors donot express hormone receptors. This means they have few or no hormone receptors. About 70% to 80% of newly diagnosed breast cancers are hormone receptor- .al., 2017) (Wang et positive
NCT01088477
In 50 breast cancer patients, heavily pretreated with anti-hormonal therapy, the investigators will evaluate the use of 16-alpha\[18-fluoro\]-17beta-estradiol positron emission tomography (FES-PET)as predictive biomarker for response to estrogen therapy.
NCT06401590
Axillary lymph node status is one of the most important prognostic factors in primary breast carcinomas. Sentinel lymph node biopsy has been increasing in post neoadjuvant setting when axillary nodes show good clinical and radiological response. It allows to determine the axillary lymph node status, which if negative, saves the patient from axillary dissection (AD) and its potential complications. To assess tumor response to neoadjuvant chemotherapy in the SLN, pathological evaluation is the gold standard. Response to neoadjuvant systemic therapy is an excellent predictor of outcome, and achievement of pathological complete response (PCR) in the SLN is a prognostic predictor of long-term outcome with significantly better disease-free survival and overall survival. Post-treatment isolated tumor cells (ITCs) and micro metastases predict worse survival compared with the same findings in the non-neoadjuvant setting. Histologically partial response to therapy, is characterized by small clusters and individual tumor cells set in hyaline stromal fibrosis. Most false negative cases had metastatic foci identified exclusively on permanent sections and are not due to a true diagnostic interpretation error. The timing of further axillary surgery, immediate or a subsequent operation should be routinely discussed at centers using intraoperative assessment of the sentinel lymph nodes, along with the potential for negative intraoperative findings and positive nodes on final pathology.
NCT02602041
The investigators will perform a pilot study to gain insight into attitudes, barriers and facilitators for health behavior change in cancer patients and their partners. Results of this pilot will be used to design suitable questionnaires to investigate health behavior change in a larger cohort of patients and their partners. It will also direct future interventions to adequately target patients and, potentially, their partners to improve their lifestyle following a cancer diagnosis.
NCT05073172
This clinical trial studies the effect of StrataXRT in preventing and treating radiation dermatitis in breast cancer or head and neck cancer patients. Radiotherapy is often associated with multiple side effects. These side effects can cause patient injury and make it difficult to complete treatment. For example, radiation dermatitis or skin damage may result in severe skin peeling and skin irritation. Depending on the location of radiation, the skin damage can cause problems and be tough to heal. This trial aims to see whether StrataXRT may help to prevent dermatitis after radiation therapy.
NCT01988324
Knowledge of breast cancer estrogen receptor (ER) expression is of major importance in treatment-decision making. Patients with ER-positive tumors can be treated with anti-oestrogen therapy, which has relatively few side effects compared to chemotherapy. Whole-body tumor ER-expression can be visualized by 18F-fluoroestradiol PET imaging (FES-PET). In addition to ER, the androgen receptor (AR) is a potential new target in breast cancer. PET imaging with 18F-fluorodihydrotestosterone (18F-FDHT) may allow visualization of tumor AR-expression. In the current study we will perform FES-PET and FDHT-PET in metastatic breast cancer patients and evaluate the concordance with concurrent biopsies. Molecular imaging of tumor AR- and ER-expression may well be of value for future treatment decision-making.
NCT03915548
This study is a randomized controlled trial (RCT) to test the efficacy of a Behavioral Activation and Problem Solving (BA/PS) approach to improving activity participation over time as compared to an attention control condition within a sample of 300 breast cancer survivors reporting reduced activity participation after completing cancer treatment.
NCT03324802
This randomized phase III trial studies how well hypofractionated radiation therapy works in preventing the return of tumor cells in breast cancer patients following surgery. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects.
NCT05807126
This phase I/Ib trial studies the side effects and best dose of Hu5F9-G4 (magrolimab) when given in combination with olaparib for the treatment of patients with breast or castrate-resistant prostate cancer that have spread from where they first started (primary site) to other places in the body (metastatic) or have come back after a period of improvement (recurrent) and have mutations in the BRCA1/2 genes. Magrolimab is a monoclonal antibody with potential anticancer activity and the cability to stimulate the immune system and may interfere with the ability of tumor cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Olaparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep tumor cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Combination therapy with magrolimab and olaparib may be safe and effective in treating BRCA-mutated metastatic or recurrent breast or castrate-resistant prostate cancer.
NCT00796978
RATIONALE: Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. PURPOSE: This phase II trial is studying the side effects of trastuzumab and to see how well it works in treating older women with early-stage breast cancer.
NCT06383663
The purpose of this study was to compare the efficacy of surgical dissection of supraclavicular lymph nodes combined with radiotherapy versus radiotherapy alone in patients with ipsilateral supraclavicular lymph node metastasis.
NCT03887130
The aim of this international open-label randomized phase II trial is to evaluate the efficacy and safety of an all-oral combination and two all-intravenous combinations as first-line therapy for HER2-negative mBC patients.
NCT01468883
Patients with biopsy proven breast cancer, clinical stage I and II, will be randomized to receive treatment by one of two methods: (1) total mastectomy and axillary dissection; or (2) excisional biopsy, axillary dissection, and definitive irradiation. Data from single institutions and from retrospective comparisons suggest that definitive irradiation with cosmetically acceptable breast preservation offers survival and local control results equivalent to extirpative surgery. This study will test this hypothesis in a prospective, randomized manner. After primary therapy, subjects will be followed for: (1) survival; (2) sites of recurrence; (3) anatomic function; (4) complications of therapy; and (5) cosmesis.
