Active clinical trials for "Breast Neoplasms"

The goal of this study is to test whether monitoring insulin levels and using pioglitazone to treat hyperglycemia and hyperinsulinemia in patients treated with Alpelisib for metastatic breast cancer is feasible and safe, and to assess the rates of glycemic control, dose reductions and treatment discontinuation and the progression free survival of patients treated with this regimen.

Determine whether subjects harboring ESR1-mutant/amplified breast cancer have a higher rate of clinical benefit from 17b-estradiol therapy than subjects with ESR1-wild-type breast cancer

This is an open-label randomized phase II study in estrogen receptor positive locally advanced or metastatic breast cancer patients. The main inclusion population are either luminal subtype B by PAM50 analysis or failed less than 2 lines of hormonal therapy for locally advanced or metastatic breast cancer. The subjects have to be premenopausal or perimenopausal and are not allowed to receive any systemic chemotherapy for their locally advanced or metastatic breast cancer. Eligible subjects will be randomized into goserelin/ fulvestrant (Arm 1, control), goserelin/ fulvestrant/ capivasertib (Arm 2), goserelin/ fulvestrant/ capivasertib/ durvalumab (Arm 3), or goserelin/ fulvestrant/ durvalumab (Arm 4) at a 1:1:1:1 ratio. The primary endpoint is objective response rate (ORR) of the whole other three arm compared to goserelin/ fulvestrant control arm. The major secondary endpoint will be progression-free survival or ORR compared among different treatment arms.

This study aimed to evaluate the use of SHR-A1811 in HER2-expression Advanced Breast Cancer patients with brain metastases.

This study was a prospective, single-arm, open-label phase II clinical trial conducted at National cancer center in China.

Triple-negative breast cancer has always been a difficult problem in clinical practice because of its young onset age, high aggressiveness, no clear therapeutic target and poor clinical prognosis. The treatment of triple-negative breast cancer is mainly chemotherapy, and in order to break the current dilemma, new treatments must be introduced. Immunotherapy is one of the most high-profile treatments. The KEYNOTE-522 study and Impassion 031 Study have found that immunotherapy can significantly improve the pCR of patients with triple yin breast cancer, rate, independent of PD-L1 expression status, and good safety.Cedardenamine is a histone deacetylation (HDAC) inhibitor developed in China.Many studies suggest that the use of sidabamine will likely enhance the efficacy of PD-1 / PD-L1 mAb in breast cancer and expand the use of PD-1 / PD-L1 mAb in the beneficiary population of breast cancer

This study is designed to see if we can lower the chance of side effects from radiation in patients with breast, kidney, non-small cell lung cancer or melanoma that has spread to the brain and who are also being treated with immunotherapy, specifically immune checkpoint inhibitor (ICI) therapy. This study will compare the usual care treatment of single fraction stereotactic radiosurgery (SSRS) given on one day versus fractionated stereotactic radiosurgery (FSRS), which is a lower dose of radiation given over a few days to determine if FSRS is better or worse at reducing side effects than usual care treatment.

The incidence of breast reconstruction failure after conventional photon radiotherapy for breast cancer is about 18.7%. At present, there is limited data on proton radiotherapy for post operative breast cancer with implantation reconstruction. Proton radiotherapy for breast cancer can significantly reduce the radiation dose of the ipsilateral heart and lung, thereby reducing the incidence of cardiac events and radiation pneumonia. This study is aimed at the study of adjuvant hypofractionated intensity-modulated proton radiotherapy for post operative breast cancer with implantation reconstruction. It can provide an ideal treatment option for such patients to effectively protect the heart and lungs without increasing the failure rate of breast reconstruction after adjuvant radiotherapy.

Studies have shown that dose-dense chemotherapy reduces the risk of recurrence and death of breast cancer patients comparing with standard-schedule chemotherapy. But some research data indicate that HR+/HER2- breast cancer patients benefit from dose-dense chemotherapy while some have negative results. How to identify HR+/HER2 breast cancer patients who are more likely to benefit from dose-dense chemotherapy is strongly necessary. Ki67 is a marker reflecting the proliferation of tumor cells. Breast cancer patients with high Ki67 are more likely to benefit from dose-dense chemotherapy. The purpose of this project is to investigate the efficacy and safety of neoadjuvant dose-dense chemotherapy for HR+/HER2- breast cancer patients with high proliferation index. At the same time, we will explore biomarkers, such as MammaPrint and BluePrint, to further identify patients who benefit more from neoadjuvant dose-dense chemotherapy.

Complete decongestive therapy is proven to be effective in reducing lymphedema related symptoms such as swelling and pain. Breathing exercises, on the other hand, may also help managing lymphedema symptoms. Deep breathing creates a pressure change in the abdomen, which creates a vacuum effect in the thoracic cavity and helps to empty the lymphatic vessels. Thus, we aimed to investigate whether addition of diaphragmatic breathing exercises to physical exercise component of complete decongestive therapy provides further benefits on lymphedema volume, pain and quality of life in patients with breast cancer related lymphedema.
