Active clinical trials for "Breast Neoplasms"

Platinum Retreated in Patients with Platinum Sensitive mTNBC

Sentinel lymph node biopsy（SLNB） is an established way of predicting axillary nodal metastasis in early breast cancer. We aim to determinethe，in a prospective randomized, controlled trial, effect of sentinel lymph node biopsy with para-sentinel lymph node(SLN) dissection versus sentinel lymph node biopsy without para-sentinel lymph node dissection on outcomes after breast surgery.

To compare disease-free survival (DFS) rate of adjuvant chemotherapy epirubicin-cyclophosphamide followed by weekly paclitaxel or docetaxel (EC-T), or weekly paclitaxel or docetaxel-carboplatin (EC-TCb) in triple-negative breast cancer.

This neoadjuvant trial for patients with TNBC and/or gBRCA breast cancer, aims to investigate the safety and efficacy (improvement in pathological Complete Response at surgery) of concurrent platinum-based chemotherapy with olaparib an inhibitor of the PARP enzyme (PARPi).

This phase II trial studies how well pembrolizumab works in treating participants with cancer that has spread to other places in the body, has come back or has spread to nearby tissues or lymph nodes. Monoclonal antibodies such as, pembrolizumab, may interfere with the ability of tumor cells to grow and spread.

Exercise in early breast cancer patients has the potential to improve depression, anxiety, fatigue, quality of life and even survival. The effects of exercise may come about by way of changes in weight, immune markers and telomere length, but data on this so far has not been conclusive. To better understand the physical, psychological, and biological effects of exercise on breast cancer survivorship, the investigators propose to perform a phase III randomized controlled trial of a 12-week exercise intervention program versus usual care in early stage breast cancer patients, and will follow up the patients prospectively for 5 years, with serial assessment of physical and functional activity, QoL, depression and anxiety scores, telomere length and plasma immune markers.

The purpose of this research study is to compare the effects (good and bad) on women and their cancer using proton radiation therapy. This study is being done to see if proton radiation therapy will prove to be beneficial for women with early stage breast cancer. A clinical study is necessary to compare the results (good or bad) of proton radiation therapy.

RATIONALE: Currently, adjuvant endocrine therapy often follows a "one-size-fits- all" approach, with most premenopausal women receiving tamoxifen, and most postmenopausal receiving aromatase inhibitor therapy. In current clinical practice, patients with invasive lobular carcinoma are treated no differently than patients with invasive ductal carcinoma based on the void of information specific to patients with this tumor type. Identification of a biological signal of tamoxifen and/or AI-resistance and/or fulvestrant-sensitivity in ILC patients would have dramatic implications for the future management of this breast cancer subtype. PURPOSE: To study whether fulvestrant is more effective than anastrozole or tamoxifen in reducing Ki67 in ILC and whether that Ki67 reduction will correlate with alterations in expression of ER and ER-regulated genes. Differential Ki67 effect in this study will serve as a surrogate for outcome of ILC patients on endocrine therapy. Primary Objective: To determine the change from baseline to post-treatment Ki67 values in ER-positive, HER2-negative ILC tissue derived from postmenopausal women awaiting definitive surgery or further neoadjuvant treatment who are randomized to 21-24 days of neoadjuvant endocrine treatments with fulvestrant (two 250 mg IM injections given on day 1), anastrozole (1mg given orally daily), or tamoxifen (20mg given orally daily).

The current study is a multicentre, randomized,double-blind, prospective clinical trial stratified patients by the HER2 status of their cancer (negative or positive) which is sponsored by the researchers. The trial is designed to evaluate the effectiveness of tamoxifen as adjuvant therapy for ER(ER-α)/PR negative, ER-β positive operable breast cancer patients. 688 female ER(ER-α)/PR negative, ER-β(wild type ER-β1) positive operable breast cancer patients who had undergone neoadjuvant chemotherapy or directly modified radical mastectomy or breast-conserving surgery were randomly (1:1) enrolled to receive tamoxifen (20 mg per day) or placebo (2# per day) within 6 weeks after postoperative chemotherapy and/or radiation therapy if needed (according to 2013 NCCN breast cancer guideline). If the breast tumor's HER2 is positive, the patient can receive targeted therapy (Herceptin) combined with tamoxifen or placebo. The follow-up time will be eight years. The aim of this trial is to evaluate the effectiveness of tamoxifen as adjuvant therapy for ER(ER-α)/PR negative, ER-β positive operable breast cancer patients by comparing the DFS and OS between tamoxifen group and placebo group and to determine whether the percentage of positive ER-β expression is associated with the response to the hormone therapy in breast cancer.

First preclinical data suggest that pegfilgrastim could constitute a potent adjuvant for immunotherapy with mAb possessing ADCC/ADCP properties as trastuzumab. Combined treatment of pegfilgrastim and trastuzumab should translate into an increased rate of pathological clinical response. Therefore the investigators' proposal is to evaluate the clinical and biological impact of pegfilgrastim in combination with trastuzumab + paclitaxel in HER2-positive early stage breast cancer patients. Breastimmune02 is a multicenter, randomized, open-label, Phase II trial. Operable HER2+ breast cancer patients previously treated with 4 cycles of standard adriamycine/cyclophosphamide (AC) chemotherapy will be randomized (1:1) to receive in the neoadjuvant setting:Arm A: weekly paclitaxel + trastuzumab (every 3 weeks, Q3W) + pegfilgrastim (Q3W) versus Arm B: weekly paclitaxel + trastuzumab (Q3W).Stratification criteria will be: cN0 versus cN1.
