Active clinical trials for "Breast Neoplasms"

This is a real world study to evaluate the efficacy and safety of inetetamb combined with pyrotinib and vinorelbine as first-line to third-line treatment after trastuzumab progression in HER2-positive metastatic breast cancer.

breast cancer is the most common cancer in women. With more than 1 in 10 new cancer diagnoses each year, It is the second most frequent cancer-related death among women worldwide. Breast cancer develops slowly, and the majority of cases are found through routine screening. breast cancer-causing deaths among women all over the world and increased in the last few years even though the treatment is advanced like immunotherapy chemotherapy by yet no treatment for triple-negative breast cancer zinc and competition between znt1 and zip6,10 at breast cancer cells. Is zinc ionophore like quercetin and EGCG has a role, In a novel experimental study zinc is a trace metal that has many roles in cells, enzymatic activity, and gene regulations, and also for the integrity of DNA. Zinc transporters (zinc related -proteins such as ZIPs, and ZnTs are affected by triggers factors like cytokines and growth factors. There are two large families of zinc transporters like ZIPs ( 14 members) and ZnTs family (10 members), ZIPS family cause an influx of zinc from the extracellular to the cytoplasm and also from intracellular organelles like endoplasmic reticulum or Golgi or mitochondria in contrast to ZnTs which cause an influx of zinc from the cytoplasm to intracellular organelles. ( lower cytoplasmic zinc) (1) Breast cancer deaths occurred from metastasis; Catalytic enzymes called proteases like cathepsin L are frequently overexpressed in aggressive cancers. Breast tumor metastatic potential is correlated with macrophage presence. These macrophages associated with tumors frequently adopt an M2-like pro-tumorigenic phenotype, which results in the production of growth hormones and proteases, notably the lysosomal protease cathepsin L. Because cathepsin L is commonly released by breast cancer cells and aids in tumor invasion, metastasis, and angiogenesis. It is expected that cathepsin L secretion by both tumor-associated macrophages and neoplastic cells would promote the metastatic phenotype because cathepsin L is widely produced by breast cancer cells and helps with tumor invasion, metastasis, and angiogenesis. (2) this study target new mechanisms and achieves the best management as some types of cancer breast like triple-negative breast cancer (TNBC) no definite treatment so we target the following pathways and epigenetic processes by these adjuvant compounds which have a promising role in the immunity like EGCG, Quercetin, Zinc, Metformin so our team will discuss novel methods to achieve the best efficacy from chemotherapy

To learn whether a new imaging technology, Contrast-Enhanced Mammography (CEM), compared to standard mammography, can better detect breast cancers in women with dense breasts

CATCH is an indication-specific diagnostic platform, which drives the implementation of integrative, genomic profiling for metastatic breast cancer into the clinics. The main objective of this approach is to identify biomarkers and drug targets to guide targeted therapeutic interventions. Eligible are all metastatic breast cancer patients (independent of gender), irrespective of molecular subtype. At initial diagnosis of distant metastasis or progress at disease progression, biopsy samples from a prognostic-relevant metastasis are retrieved during standard-of-care procedures for central analyses, together with blood samples. In parallel to all standard-diagnostic measures, genomic and transcriptomic profiling is conducted to infer the underlying biology of the disease and identify patients who might profit from biomarker-guided interventions in clinical trials. Samples not required for standard-of-care clinical procedures or genomic profiling are systematically collected in a dedicated bio-repository to fuel translational scientific companion programs. The continuously growing comprehensive database serves as an integrative resource for systematic, prospective multidimensional data collection (clinical records, biomaterial, genomic data). In summary, the overarching goal is to generate a precision oncology platform to i) identify clinically-actionable biomarkers and drug targets that drive genomics-guided therapies and ii) couple the observational, diagnostic registry platform to an increasing number of independent, biomarker-stratified clinical therapy trials (CATCH-GUIDE).

In this study, it was investigated whether the premedication drug administered before the surgery had an effect on postoperative pain and anxiety scores in female patients under the age of 65 who will undergo breast cancer surgery.

Breast cancer is the most common malignant tumor in women worldwide and neoadjuvant therapy has been the standard care for local advanced breast cancer. Moreover, neoadjuvant therapy undoubtedly provides an ideal model to evaluate the response to therapy. Cell-in-cell structures (CICs) refer to the presence of one or more cells inside host cell, which generally leads to the death of inner cells. Notably, established evidences indicated that CICs were present in breast cancer and tend to impact patient survival. However, whether CICs profile could predict efficacy of therapy remains unclear. In this prospective cohort study, the CICs number and profile will be detected in tumor tissue before and after the neoadjuvant therapy. Then the association between CICs number including dynamic changing and response rate will be explored.

In the present prospective study, we will analyze the outcome of image-guided delivery of intra-arterially infused chemotherapeutic drugs for patients with breast cancer in III, IV stages.

This phase II trial tests how well propranolol and pembrolizumab work to cause tumor re-sensitization and therefore treatment in patients with triple negative breast cancer that has not responded to previous checkpoint inhibitor therapy (refractory), cannot be removed by surgery (unresectable) or has spread from where it first started (primary site) to other places in the body (metastatic). Propranolol is a drug that is classified as a beta-blocker. Beta-blockers affect the heart and circulation. Beta-blockers, like propranolol, may help to counteract effects of certain stress hormones produced by the body during cancer treatment and may increase the effectiveness of the pembrolizumab. Pembrolizumab is a drug that is classified as an immune checkpoint inhibitor. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Propranolol may be able to re-sensitize the cells of the immune system to respond to the checkpoint inhibitor pembrolizumab in patients with checkpoint inhibitor refractory metastatic or unresectable triple negative breast cancer.

Extracellular vesicles (EVs) are lipid bilayer-delimited particles, naturally released from the cells and mediators of intercellular cross-talk. In breast cancer (BC), EVs seem to be involved in the tumor microenvironment's shaping, in cancer cells invasion and in the set-up of metastasis. Clinical studies have provided initial evidence that EVs may have a prognostic and predictive value in breast cancer. Considering their presence in body fluids and their minimally invasive assessment through blood sampling, EVs could be liquid biopsy-derived biomarkers. Their quantification could be a complex challenge, requiring complicated and time-consuming pre-analytical procedures of EVs isolation. A new method for the detection of tumor-derived-EVs associated proteins is based on the use of Single Molecule Array (SiMoA), a digital ELISA technology able to detect and quantify extremely low concentrations of target proteins or particles. The aim of this study is to evaluate how this new technology can allow the quantification EVs plasma levels in patients affected by BC, providing useful diagnostic and prognostic information about the efficacy of the neoadjuvant treatment.
