Active clinical trials for "Triple Negative Breast Neoplasms"

This is a prospective, single-center, non-randomized, non-controlled observational study.

This study is looking at how an imaging test could help doctors understand if a patient with early breast cancer will respond to drugs that use the patient's immune system to fight cancer.

This study is the experimental study for serial ctDNA and exosome evaluation in EBC patients

This is an observational case-control study of tissues collected from women with ER+HER2- breast cancers. The immune environments of these cancers will be compared to triple negative and HER2+ breast cancers. No randomization or changes to standard of care treatment will occur as part of the study.

This study is a genetic analysis of aberrations in circulating tumor DNA (ctDNA) in patients in Asian countries. This study protocol is divided into parts describing several subanalyses that differ in terms of cancer types, analytical methods, participating countries, and participating institutions.

Initially described in 2009 on LGR5 positive stem cells from intestine, organoids correspond to a 3D cell culture that preserves the organization and part of the initial function of the organ from which the cells were derived. They use the proliferation and differentiation properties of stem cells cultured in a three-dimensional matrix. These principles have been adapted to many human organs, including the breast. These culture conditions have thus allowed the establishment of cancer organoid lines that have the advantages of rapid amplification, a high rate of establishment success and unlimited proliferation potential. They are transfectable and cryopreservable. They are very close morphologically and genetically to the tumor from which they derive. Very recently, the in vivo response of orthotopic xenograft models of breast cancer organoids has been correlated to the in vitro response of these same organoids. In addition, the in vitro response of various of these models to PARP inhibitors was linked to the presence of the BRCA1/2 mutant signature, highlighting the potential of these models to predict patient response to these treatments. Furthermore, one study demonstrated the value of using organoids derived from metastatic gastrointestinal tumors to predict patient response to cancer treatments (100% sensitivity, 93% specificity, 88% positive predictive value, and 100% negative predictive value.

Patients with Her-2 positive and triple negative breast cancer who received neoadjuvant chemotherapy will be included in the study. Paraffin blocks of preoperative core or tru-cut biopsies of the participants will be collected and tested for programmed death-ligand 1 (PD-L1) expression. The variation of PD-L1 expression among different breast cancer subtypes will be evaluated and the investigator will correlate between PD-L1 expression and pathological complete response to neoadjuvant systemic therapy.

This is a prospective and observational study, aiming to determine the detection rate and change of CtDNA in blood samples of cancer patients before, during and after neoadjuvant treatment. Determine the rate of ctDNA positivity at the time before treatment, Determine the rate of ctDNA positivity at the time during treatment, Determine the rate of ctDNA positivity at the time after neoadjuvant therapy, whether there is a change in ctDNA expression of the study population during treatment. And aiming to investigate the relationship between ctDNA expression and MRI imaging with pCR response in neo-adjuvant therapy: Correlation between ctDNA detection and pCR response. Determine the percentage of Positive Prediction Value - PPV, Negative Prediction Value - NPV of ctDNA, Correlation between MRI imaging and pCR response. Determination of PPV, NPV of MRI Combination of ctDNA detection and MRI imaging in the prognosis of pCR. Determination of PPV, NPV ratio of ctDNA combined with MRI.

The goal of the project is to identify a molecular signature of tumor stroma from "normal" adjacent breast tissue obtained prospectively at the time of breast conserving surgery before and after receiving intraoperative radiation therapy (IORT) in subjects that have luminal A and triple negative breast cancer. IORT is considered as being standard of care.

It analyzes the Tumor microenvironment(TME) changes in non pathologic complete response(pCR) subjects among subjects who were administered neoadjuvant pembrolizumab and those who were not administered neoadjuvant pembrolizumab for triple negative breast cancer. (Neoadjuvant Weekly paclitaxel, Carboplatin +- Pembrolizumab followed by Doxorubicin, Cyclophosphamide +- Pembrolizumab regimen)
