Active clinical trials for "Breast Neoplasms"

This randomized controlled trial compares vacuum-assisted percutaneous excision to open standard surgical excision in women who have high-risk or borderline, non-malignant breast lesions with respect to efficacy, safety, cosmesis and patient satisfaction.

Neoadjuvant chemotherapy is a systemic cytotoxic drug therapy for non-metastatic tumors before local therapy, Now it has become an important part of standard treatment for a stage II, III, and the first clinical Ⅳ breast cancer .Both domestic and foreign authoritative guidelines recommend the use of albumin-binding paclitaxel in the neoadjuvant treatment of breast cancer .In addition, clinical studies at home and abroad have preliminarily confirmed the application value and therapeutic benefit of albumin-binding paclitaxel in breast cancer neoadjuvant therapy, and the toxic and side effects can be tolerated.

to assess the effect of dalpiciclib plus letrozole and capecitabine of first-line treatment with breast cancer

ISIdE is an European, multicentric study that aims to assess the efficacy of Sacituzumab Govitecan (SG) in locally advanced or metastatic triple-negative breast cancer where the disease has progressed despite chemotherapy or within 6 months after the end of curative treatments in order to: evaluate the treatment efficacy in less pretreated patients. identify biomarkers that could predict response or resistance to the drug. 100 patients will be included in this trial.

In the last decades, the proportion of breast cancer (BC) patients receiving breast-conserving surgery has increased steadily, reaching 70-80% in developed countries. Since positive resection margins are strongly associated with local recurrence risk, the goal of breast surgery is the complete tumor removal and most national and international guidelines recommend re-operation, either in form of re-excision or mastectomy, until clear margins have been reached. Re-operation rates vary widely, with population-based studies reporting a range of 15-35%, and the necessity for a second surgery can lead to increased patient anxiety, a delay in start of adjuvant treatment, worse cosmetic outcome and increased complication rates and costs. Therefore, re-operation rate has been included as a quality indicator in several countries. Several imaging-guided techniques have been developed to guide removal of non-palpable breast lesions, the oldest one being preoperative wire placement under ultrasound or mammographic guidance, usually followed by radiography or ultrasound of removed tissue. Newer techniques, such as intraoperative ultrasound (IOUS), radioguided occult lesion localization (ROLL), radioactive seed localization (RSL), radar reflector-localization (RRL), magnetic seed localization (MSL), and radiofrequency identification (RFID) tags have been introduced as an alternative to wire-guided localization (WGL). To date, comparative data on the rates of successful lesion removal, negative margins, re-operation rate and patient's comfort depending on the localization technique used are limited. Further, since some of these studies were funded by the manufacturer of the marker examined, a potential bias cannot be excluded. In the vast majority of the available studies, the patient's perspective with regard to discomfort and pain level has not been evaluated. The aim of the proposed study is to comparatively evaluate different imaging-guided localization methods used for surgical removal of malignant breast lesions with regard to oncological safety and patient-reported outcomes.

This study is a prospective, single-arm, phase II clinical study for patients with ER+/HER2+ advanced breast cancer.

The investigators propose a randomized phase II clinical trial of talazoparib maintenance therapy in TNBC patients whose tumor showed clinical benefit (platinum-sensitivity) to first- or second-line platinum-based chemotherapy (monotherapy or combination with other agents). Patients are eligible when they meet at least one of two following platinum-sensitivity criteria: They should have received 6 tri-weekly doses or 18 weekly doses of platinum-based therapy in non-progression status (at least stable disease) at the time of enrollment; They should remain in complete or partial response status after 4-6 tri-weekly doses or 12-18 weekly doses of platinum-based chemotherapy. Eligible patients are enrolled to the trial within 4 to 8 weeks after last chemotherapy and 1:1 randomized to receive talazoparib versus placebo maintenance therapy. The primary endpoint is PFS by RECIST 1.1 after randomization. The secondary endpoints include OS, time from randomization to second progression or death (PFS2), and objective response rate (ORR) by RECIST 1.1, adverse events by CTCAE 5.0 criteria, quality of life evaluated by EORTC-QLQ-C30, and EuroQoL EQ-5D.

This study assesses the performance status in stage I-III triple negative breast cancer patients who are receiving neoadjuvant chemotherapy. Information collected in this study may help doctors learn if movement and fitness trackers can be used to predict side effects in cancer patients receiving chemotherapy.

SMMART-ACT is a feasibility pilot study to determine if testing samples from a participant's cancer using a precision medicine approach can be used to identify specific drugs or drug combinations that can help control their disease. The safety and tolerability of the drug or drug combination is also to be studied. Another purpose is for researchers to study tumor cells to try to learn why some people respond to a certain therapy and others do not, and why some cancer drugs stop working. The study population will include participants with advanced breast, ovarian, prostate, or pancreatic malignancies, or sarcomas.

The trial used a multicenter, open, single-arm design in which patients were treated with Chidamide combined with Fulvestrant.The primary objective is to evaluate the preliminary efficacy and safety of Chidamide in combination with Fulvestrant.Patients included in the trial were advanced breast cancer progressing on first-line aromatase inhibitor + Cyclin-dependent kinases（CDK）4/6i rescue therapy.
