NCT04438564
The immune system is our body's defense mechanism, which helps us to resist foreign pathogens and cancer cells in the body. However, if the immune system is too weak, too strong, or unbalanced, it will be susceptible to get bacterial and viral infections, unable to fight cancer, or cause allergies, autoimmune and rheumatic diseases. At present, there is no good western medicine to strengthen immunity when the body is insufficient immunity. However, strong immunity causes autoimmune diseases and need to be treated by steroids and immunosuppressive agents. These drugs have limited efficacy and often have many side effects. In the clinical practice of traditional Chinese medicine, tonify qi, supplement blood and nourish yin are often used to enhance immunity. However, there is no clinical test to demonstrate the modulation of immune response after traditional Chinese medicine treatment. In our preliminary study, the investigators identified that the basic immune response of cancer patients is weaker than healthy people by testing the level of IFN-r (promoting T cell activity, anti-tumor, anti-viral), TNF-a (promoting B cell proliferation, producing antibodies, anti-tumor, anti-viral) and IL-2 (regulate the proliferation and differentiation). Besides, some Chinese herbal extracts can significantly stimulate the immune response higher than the general average basic immunity of cancer patients. Further, we will use the stimulatory Chinese medicine extract to administer to cancer patients and examine the immune response of cancer patients after taking them. Therefore, this test can provide actual data on the basic immunity of healthy people or cancer patients and the modulation of immune response by traditional Chinese medicine treatment. This analysis platform provides patients to select the medicines that can enhance the immune response for individuals and analyze the changes of the immune response after conditioning with the candidate Chinese medicines. Therefore, this test could be applied clinically to validate the immunological regulation of Chinese herbal medicine as well as analyze the immunological modulation against different cancer by various Chinese herbal medicine.

NCT04514159
This is a Phase 1b, open-label, multicenter, dose-escalation study to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary efficacy of ZN-c5 administered orally in combination with abemaciclib (VERZENIO®) in participants with advanced estrogen-receptor positive, human epidermal growth factor receptor-2 negative (ER+/HER2-) breast cancer.
NCT04815616
1- Determine the efficacy and safety of concurrent capecitabine and external beam irradiation in patients with early stages breast cancer.
NCT01704547
The study is designed to assess the accuracy of patient breast reproducibly using the revised BCID. This study would provide data for target verification and quality assurance to eventually allow treatment of breast cancer patients for either a TBB or accelerated partial breast irradiation. The BCID is a low-risk device similar to immobilization devices used routinely in radiotherapy for other disease sites.
NCT05708664
From 2021 to 2022, 31 patients with unifocal breast cancer were enrolled for precision breast conserving surgery (PBCS) guided by wire guided localization (WGL) combined with CT guided 3D reconstruction. Surrounded WGL was performed under local anesthesia, followed by an immediate contrast enhanced CT scan. PBCS guided by CT guided 3D reconstruction was performed one day after the localization. Women who underwent palpation guided breast conserving surgery (BCS) were included as control. Two-sided Student t test, Fisher's exact test and chi-square test was applied.
NCT01684735
Evaluation of the response to chemotherapy in breast cancer patients by the use of Diffusion-weighted magnetic resonance imaging of the breast before the start of chemotherapy, after one and 3 cycles of therapy and at the end of the therapy.
NCT05703815
Breast cancer represents the most frequently diagnosed cancer in women. It represents the 5th leading cause of cancer mortality all over the world. In Egypt, breast cancer represents the 2nd most diagnosed cancer among all population. But among Egyptian females it represents the 1st diagnosed cancer representing 32.4%. The main cause of death in breast cancer patients is tumor metastasis. Although only 5-10% of recently diagnosed breast cancer cases show metastasis to distant sites, but still there is a high risk for metastasis in patients with localized primary tumor following successful surgical management. Epithelial cell adhesion molecule (EpCAM) is a cell adhesion molecule. It modifies cadherin mediated cell adhesion and it induces epithelial cell migration and proliferation. Some authors elucidate that EpCAM is involved in metastasis. P53 is a known tumor suppressor gene involved in the control of cell cycle, DNA repair and apoptosis. It's one of the most mutated genes in cancer including breast cancer. Mutant p53 has a big role in tumor progression.
NCT03732391
This is a prospective two-stage single arm phase II study to be conducted in conformance with Good Clinical Practices. This study will enrol 53 patients, based on a two steps Simon's design. Patients will entry into the study if the following conditions will be satisfied: * BRCA1/2 germline mutations. * Metastatic disease with measurable lesions will be evaluated by computed tomography or by PET (Positron Emission Tomography) scan. * Patients must have received anthracycline and taxanes before entry into the study. Patients will be treated with Carboplatin AUC6 (Area Under The Curve) EV (endovenous) every 3 weeks in combination with Pembrolizumab 200 mg EV every 3 weeks for 6 cycles. Afterwards, the Pembrolizumab will recontinued with the same schedule until unacceptable toxicity or disease progression. The primary endpoint will be Objective Responses Rate (ORR) (complete answers + partial answers) evaluated according to the RECIST criteria.
NCT05609058
Radiotherapy after breast conserving therapy plays an important role in early stage breast cancer patients. It not only results in a reduction in local and regional recurrence but also decrease the death rate effectively. For adjuvant radiotherapy, supine positioning is the most common approach and has multiple advantages. Due to deformability and softness of the breast, during simulation and treatment in supine position, the breast stretches over the chest wall, especially in patients with large and pendulous glands. Thus the organs at risk (OARs) received dose increased. The radiotherapeutic toxicity are unavoidable. Some present studies show that the prone positioning of patients can improve dose homogeneity and reduce the dose distribution in OARs in patients with large and pendulous glands. Chinese women have relatively small breasts, the advantages of those have not been established. Therefore, investigators compared the parameters between supine and prone positions for whole breast irradiation after conserving surgery.
NCT03982173
To determine the efficacy (as measured by overall tumour response rate) of the combination of durvalumab and tremelimumab when given to previously treated patients with solid tumors harboring a high mutational load.
NCT05699577
breast cancer is the most common type of cancer in women and first cause of cancer death among them. in Egypt it constitutes 33% of female cancer cases and more than22000 new cases diagnosed each year. there are many prognostic factors for breast cancer as Tumer size, axillary lymph node status, hormonal receptor status, and tumer markers as Ca15-3 and interferon gamma.
NCT02652923
This is a two part, open label, non-randomized trial of women with a breast cancer diagnosis scheduled for excisional surgery and sentinel lymph node (SLN) evaluation. Part 1 is a two-period, crossover, dose-finding study, which will be performed in 12 healthy female volunteers to determine the optimal dose as well as the safety and tolerability of the tissue-specific, contrast agent Sonazoid (GE Healthcare, Oslo, Norway) for human lymphatic applications. In Part 2 lymphosonographic SLN identification will be compared to that of isotope mapping during surgery on 90 female, breast cancer patients.

NCT01625286
The purpose of this study is to investigate the safety and efficacy of different doses and schedules of AZD5363, when in combination with paclitaxel, in treatment of patients with advanced or metastatic breast cancer. Also to investigate a selected dose and schedule of AZD5363 in combination with paclitaxel vs. paclitaxel in combination with placebo in treatment of patients with estrogen receptor-positive advanced or metastatic breast cancer, including a subgroup who have the phosphoinositide-3-kinase, catalytic, alpha polypeptide (PIK3CA) tumour mutation.
NCT04574063
A randomised controlled trial in which women discharged from the symptomatic breast clinic, who are above population risk (according to Tyrer Cuzick) will be asked to create lifestyle related goals. They will be told their estimated risk of developing breast cancer and will be randomised to one of three interventions: * Breast cancer risk leaflet only * lifestyle website * lifestyle website plus group coaching. Fifty per cent of women will also be randomised to have Single Nucleotide Polymorphisms (SNPs) performed, and these will be incorporated into their risk score. The primary end point will be whether or not women achieve their lifestyle goal.
NCT04582968
Brain metastases occur in 30-50% of patients with metastatic HER2-positive breast cancer. Pyrotinib is an irreversible pan-ErbB receptor tyrosine kinase inhibitor (TKI) with activity against epidermal growth factor receptor (EGFR)/HER1, HER2, and HER4. This study consists of two parts. In a phase Ib part, investigators will explore the safety and tolerance of Pyrotinib Plus Capecitabine combined with brain radiotherapy. After completing the phase Ib part, investigators will review the data and decide whether this patient is included in before the start of a phase II part. In the phase II part, investigators will evaluate the efficacy of Pyrotinib Plus Capecitabine combined with brain radiotherapy in patients with HER2 positive breast cancer patients with brain metastases.
NCT04579029
Lymphoedema is a chronic debilitating disease that can have severe adverse effects on day-to-day life causing great physical and visual discomfort. The clinical presentation is characterised by chronic swelling of limbs, accompanied by localised pain, skin changes and recurrent infections. It is caused by a disruption in lymphatic flow which prevents the normal circulation of interstitial fluid (situated in the spaces between the cells of the body), resulting in swelling of the affected limb. It can be primary (cause unknown) or secondary to a number of causes such as malignancy, trauma, surgery, radiotherapy, infection, or venous disease. In breast cancer treatment, axillary surgery and radiotherapy significantly damage normal lymphatic drainage of the upper limb, causing lymphoedema in 1-in-5 patients. There is a growing body of evidence that this chronic and debilitating condition can be better managed through early surgical intervention rather than the current conservative management, which rely on pressure garments and massage. This surgical intervention, lymphaticovenous anastomosis (LVA), joins up a number of the draining lymphatic vessels to correspondingly sized veins on the affected limb using microsurgical techniques. A special dye and camera system is used to facilitate identifying lymph vessels. This creates a new drainage pathway for the lymph fluid around the area of disruption, improving lymphatic flow. Volume reduction is expected and this would be expected to provide quality of life benefits for the patients. This study seeks to compare the outcomes from both therapies and determine whether LVA surgery can help to improve the physical burden and quality of life for patients affected by lymphoedema. Furthermore, lymphoedema places a substantial burden on NHS services. If this trial is successful, LVA surgery could improve patient outcomes and reduce the overall cost of treatment.
NCT04248998
Glucose starvation and metformin have synergistic antitumor effects that are mediated through the concomitant inhibition of glycolysis and mitochondrial oxidative phosphorylation. The BREAKFAST trial will evaluate the antitumor activity of combining cyclic fasting-mimicking diet (FMD), which reproduces the in vitro effects of glucose starvation, plus/minus metformin with standard preperative anthracycline-taxane chemotherapy in patients with stage I-III TNBC
