Active clinical trials for "Breast Neoplasms"

This phase I trial studies the side effects and best dose of multiantigen deoxyribonucleic acid (DNA) plasmid-based vaccine in treating patients with human epidermal growth factor receptor 2 (HER2)-negative stage III-IV breast cancer. Multiantigen DNA plasmid-based vaccine may target immunogenic proteins expressed in breast cancer stem cells which are the component of breast cancer that is resistant to chemotherapy and has the ability to spread. Vaccines made from DNA may help the body build an effective immune response to kill tumor cells.

This is a two stage study, with an initial dose escalation phase I study and subsequent double blind randomised phase II controlled trial. Eligible patients are post-menopausal women with metastatic ER+ breast cancer not suitable for surgical resection. Patients should be suitable for endocrine treatment, but have received no more than 3 previous lines of endocrine treatment and up to 1 line of chemotherapy for metastatic disease. They will also have had progressive disease during treatment with an aromatase inhibitor. Following the dose-escalation in stage 1, patients will be randomised to receive fulvestrant plus either placebo or 480mg (or maximum tolerated dose) of AZD5363 oral capsules or tablets taken once daily. Patients will receive fulvestrant in combination with either placebo or AZD5363 until disease progression. Patients may continue to receive fulvestrant and AZD5363/placebo treatment even after the last trial visit.

Olaparib treatment in patients with germline BRCA1/2 mutations and high risk HER2 negative primary breast cancer who have completed definitive local treatment and neoadjuvant or adjuvant chemotherapy

This phase I trial studies the side effects and the best dose of Z-endoxifen hydrochloride in treating patients with estrogen receptor-positive (ER+) breast cancer that has spread to other places in the body (metastatic) or has come back at or near the same place as the original tumor (locally recurrent). Estrogen can cause the growth of breast cancer cells. Hormone therapy using Z-endoxifen hydrochloride may fight breast cancer by blocking the use of estrogen by tumor cells.

The aim of this study is to evaluate the safety and efficacy of Cohesive Silicone Gel-Filled Breast Implant (CoSBI) produced by HansBiomed co.,Ltd. in breast reconstruction or augmentation

Primary objective: To evaluate the disease-free survival (DFS) in the two randomized arms after therapy with LC vs. EC in chemo-naive Her2-patients with stage I or II breast cancer Secondary objectives: To assess the overall survival (OS) To establish the safety profile by assessing the toxicities and tolerability To assess the quality of life (QoL) To evaluate survival correlation with biomarkers expression.

Currently the standard of care is to treat early stage invasive breast cancer or ductal carcinoma in situ (DCIS) with a combination of lumpectomy and radiotherapy, known as "breast-conserving therapy" (BCT). The traditional method of giving radiation therapy after a lumpectomy is to the whole breast. However the investigators do not know if the whole breast needs to be receive radiation to better control your cancer or only a more limited area of the breast surrounding the tumor. The purpose of this study is to see the side effects of delivering partial breast irradiation (PBI) instead of whole breast irradiation (WBI). PBI is radiation therapy given only to the area of the breast where the cancer was removed. Another purpose of this study is to look long term at the rate at which cancer comes back in the same breast after PBI. WBI is radiation therapy given 5 days a week for 5 to 7 weeks to the whole breast. Partial breast irradiation radiation therapy (PBI) is much shorter than whole breast irradiation. The investigators propose to deliver the PBI radiation therapy, for a few minutes a day, once a day, five days a week, for 2 weeks. In this study the investigators will learn about the good and bad effects of PBI radiation therapy. In this study, the investigators will also learn about how the breast looks after surgery and radiation therapy.

The purpose of the study is to evaluate the benefit of adjuvant chemotherapy on overall survival for elderly patients with breast cancer, in a sub group with a high risk of relapse according to Genomic Grade test.

Before anti-estrogens such as tamoxifen were developed to treat estrogen receptor (ER)-positive breast cancer, high-dose estrogen therapies were used. This seems counterintuitive since anti-estrogens block ER function, while estrogens increase ER function, but these therapies are effective to similar extents for the treatment of metastatic ER+ breast cancer. Estrogen therapies are most effective against cancers that develop resistance to anti-estrogens, likely because such cancers have adapted to grow without ER function, and restoring ER function (with estrogen) is damaging to the cancer cells. In some patients with ER+ breast cancer that becomes resistant to anti-estrogens, treatment with the estrogen 17B-estradiol induces tumor response. Furthermore, when 17B-estradiol-sensitive tumors eventually become resistant to 17B-estradiol, switching back to anti-estrogen therapy is often effective. These observations suggest that cancers can alternate between anti-estrogen-sensitive and 17B-estradiol-sensitive states. The investigators hypothesize that treatment with alternating 17B-estradiol / anti-estrogen therapies on a defined 8-week / 16-week schedule will more effectively prevent cancer growth than continuous treatment with either type of therapy in patients with metastatic anti-estrogen-resistant ER+ breast cancer.

This randomized phase III trial studies standard or comprehensive radiation therapy in treating patients with early-stage breast cancer who have undergone surgery. Radiation therapy uses high-energy x rays to kill tumor cells. It is not yet known whether comprehensive radiation therapy is more effective than standard radiation therapy in treating patients with breast cancer
