Active clinical trials for "Breast Neoplasms"

This is a real world study to evaluate the efficacy and safety of tyrosine kinase inhibitors after T-DM1 progression.

This study is a single-arm,exploratory clinical study, to evaluate the effectiveness and safety of apatinib mesylate combined with albumin-bound paclitaxel for second-line treatment of advanced triple negative breast cancer.

Neoadjuvant systemic treatment for breast cancer (used in locally advanced and operable breast cancer) includes anthracycline based chemotherapy (Doxorubicin/Cyclophosphamide) followed by taxanes (weekly Paclitaxel or Docetaxel) with antiHer-2 Trastuzumab or dual antiHer-2 Trastuzumab plus Pertuzumab. Other regimens include Docetaxel plus Carboplatin plus Trastuzumab alone or combined with pertuzumab for Her-2 positive patients. The tumor microenvironment, which includes extracellular matrix and stromal cells, is a key factor in tumorigenicity and the prediction of the efficacy of immunotherapy, conventional chemotherapy, and other anticancer therapies. Tumor-infiltrating lymphocytes (TILs), one of the most important components of the tumor microenvironment, were reported to predict the response to NAC both for tumors and axillary lymph nodes in breast cancer patients. This study is conducted to examine the relationship between tumor-infiltrating lymphocytes (categorized into three levels) and the pathologic complete response to neoadjuvant systemic therapy in breast cancer patients, and to examine the relationship between TILs and 1-year invasive disease-free survival (IDFS).

This is a prospective observational cohort study. Breast cancer and lymphoma patients planned to receive cytotoxic therapy will be recruited at Yale and Mayo Clinic. The Study Period is 9 months, during which enrolled patients will use their personal smartphone, computer, or other web-connected device to connect with the Hugo platform which will deliver PRO questionnaires, and sync to the wearable device in the study (Fitbit). The PerfO (6MWT) will be conducted twice in clinic during the study period. Structured information from the electronic health record (EHR) and patient portals will be collected and where needed, the EHR will be directly reviewed to record AEs, hospitalizations/emergency department visits and dose delay/reductions. Required in-person face to face visit is only at baseline for consent, enrollment and receipt of wearable device; patients can be followed remotely afterward (i.e. do not need to be treated at Mayo or Yale)

Currently, data of the efficacy of trastuzumab plus pertuzumab and chemotherapy is limited in the HER2 positive metastatic breast cancer patients previously treated with trastuzumab during (neo)adjuvant and metastatic setting, and results are not consistent.The main purpose of this study is to evaluate the 6-month progression free survival(PFS) of trastuzumab(Henlius®) combined with Pertuzumab(Perjeta®) and Chemotherapy as first to third line therapy in Chinese patients with HER2 positive metastatic breast cancer who received trastuzumab previously.Primary Endpoint is 6-month Progression-free survival (PFS);Secondary Endpoint(s) include Progression-free survival (PFS) Overall Survival (OS);Objective Response Rate(ORR);

This project is a prospective, clinical cohort study initiated by researchers to study the high-risk factors affecting the overall survival of newly diagnosed ER + / HER2 - advanced breast cancer patients and to establish a prediction model of ER + / HER2 - advanced breast cancer patients affecting overall survival. This project is the first prospective prediction model for the survival of patients with advanced breast cancer, and it is also the first time to establish a survival prediction model for ER-positive / HER2 negative advanced breast cancer suitable for China's national conditions. According to the survival outcome predicted by the model, the newly diagnosed ER positive / HER2 negative advanced breast cancer was divided into three groups: low, medium, and high risk, which provided an important theoretical basis for further design of randomized controlled clinical research and guidance of individualized precise treatment scheme for different groups in the future.

The purpose of this study is to find out whether it is safe to perform MRI scans in people who have breast tissue expanders in place.

This study is an open-label, single-arm, phase I study of irinotecan liposome injection in patients with advanced breast cancer. The purpose of this study is to evaluate the safety, efficacy and pharmacokinetics of irinotecan liposome injection in patients with advanced breast cancer.

The surgical method for breast cancer is determined according to the size and location of the remaining lesions after prior chemotherapy. There are many patients who were able to undergo partial resection when confirming the final results of patients who underwent total resection after prior chemotherapy. Therefore, we would like to investigate whether it is effective to make decisions based on the results of pre-operative tests after prior chemotherapy.

This is a multi-center,randomized,phase 3 clinical trial. In the study, HER2-positive metastatic breast cancer patients with abnormal activation of PI3K/Akt/mTOR pathway after progression on trastuzumab are enrolled and randomized to receive the treatment of Inetetamab plus Rapamycin plus chemotherapy or Pyrotinib plus chemotherapy.The study aimed to access the efficacy and safety of Inetetamab combined with Rapamycin and chemotherapy in HER2-positive metastatic breast cancer patients with abnormal activation of PI3K/Akt/mTOR pathway.
