Active clinical trials for "Breast Neoplasms"

Erector spinae plane block (ESPB) is a recently described block. Although there is still no consensus of its mechanism, the published case series seems to promise a new regional anesthesia technique for both chronic and acute pain. In this clinical trial, the postoperative analgesic effect of ESPB will be studied in patients underwent unilateral breast cancer surgery.

A central challenge in the fight against breast cancer is how to detect disease in a noninvasive manner before it is detectable by imaging methods. Although inroads have been made with more sensitive imaging techniques for earlier detection of breast cancer, these techniques are limited by the size of lesion that could be detected. Alternatively, several blood proteomic biomarkers have been proposed but none offer as of yet sufficient predictive power. Consequently, effective non-invasive tools as prognostic indicators and biomarkers of breast cancer are urgently needed. The purpose of this study is to develop and test non-invasive biomarkers based on methylation changes in PBMC and circulated tumor DNA in breast cancer patients.

The treatment of the patients with metastatic breast cancer remains a major problem. However, there is an intermediate state between the primary tumor and distant metastases called oligometastasis. Current research indicates that good local control of oligometastasis can be obtained with Stereotactic body radiotherapy (SBRT) Can not prolong the long-term survival of patients. Researchers believe that after SBRT treatment of patients with oligometacosis in breast cancer, it is necessary to explore whether the anti-angiogenic therapy targeted drug apatinib can reduce the occurrence of new lesions and prolong the survival of patients.

Intraoperative radiotherapy (IORT) is a type of accelerated partial breast irradiation (APBI) in which radiation therapy is delivered to the breast tissue in a single treatment at the time of lumpectomy for breast cancer. The Xoft device (Axxent, Xoft, San Jose, CA) is a device that allows for IORT for breast cancer using kilovoltage (kV) photons. A central goal of this study is to report acute and late toxicities and cosmetic outcomes following breast IORT with the Xoft device in women with early-stage breast cancer treated with lumpectomy. The investigators hypothesize that IORT following lumpectomy will be safe and well tolerated with a lower rate of physician reported acute side effects than traditional whole breast radiation therapy after lumpectomy.

Prospective, open label, multicenter, group sequential response adaptive randomized phase 2 study, comparing two treatments for locally advanced or metastatic luminal breast cancer: Arm A: concomitant cyclin-dependent Kinase 4/6 (CDK4/6) inhibitor (palbociclib, ribociclib or abemaciclib) plus endocrine therapy (aromatase inhibitor [AI] or fulvestrant) Arm B: chemotherapy plus endocrine therapy (AI or fulvestrant, administered either concomitantly from the beginning of chemotherapy or sequentially after 4-6 months of chemotherapy) Treatments will continue until disease progression or toxicity or patient refusal.

This is an open-label, multicenter, dose-escalation and parallel-group expansion Phase II clinical trial to evaluate the efficacy, safety and tolerability of KN026 in combination with palbociclib and fulvestrant in women or male with HER2-positive metastatic breast cancer .The subjects will receive 20 mg/kg IV Q2W+ palbociclib 100/125 mg/day orally+/-Fulvestrant 500 mg IM until progressive disease, unacceptable toxicity or death.

This is a single-arm, open-label, multicenter, phase II study to evaluate the efficacy and safety of SG001 in combination with Nab-paclitaxel in patients with advanced TNBC.

The hypothesis of this study is to discover the efficacy and safety of trastuzumab combined with pyrotinib in treating advanced breast cancer with HER2 positive, which is detected by digital PCR. It is a single-arm, multicenter phase II clinical study. The purpose of this study is: To explore the Response rate (RR) and progression-free survival(PFS) and safety of patients with recurrent metastatic breast cancer who received trastuzumab combined with pyrotinib in positive plasma HER2 amplification detected by digital PCR. To explore the potential using of digital PCR in recurrent and metastatic breast cancer.

Abbreviated Title :Pembrolizumab with paclitaxel in hypermutated breast cancer Trial Phase: Phase II Clinical Indication: Hormone receptor-positive metastatic breast cancer Trial Type: Interventional Type of control: None Route of administration: Intravenous Trial Blinding: None Treatment Groups : Pembrolizumab plus paclitaxel Number of trial participants: Approximately 200 patients will be prescreened with whole exome sequencing. Then 52 patients will be enrolled in the treatment phase. Estimated enrollment period :12 months Estimated duration of trial :The sponsor estimates that the trial will require approximately 24 months from the time the first subject signs the informed consent until the last subject's last visit. Duration of Participation :24 months Estimated average length of treatment per patient :8 months

Different modalities for breast cancer treatments have exhausting and distressing side effects and toxicities leading to decreased compliance. Thus, repurposing drugs with accepted safety profile and possible antitumor activity becomes an eminent constraint. Statins have been reported to have possible advantages as anticancer, and control of cancer progression. Moreover, they can sensitize cancer cells for radiotherapy. Therefore, the investigators aim to investigate the effect of (pitavastatin) added to conventional chemotherapy protocols for breast cancer patients.
