Sentinel lymph node biopsy (SLNB) has become the standard procedure for staging of patients with clinically node-negative breast cancer. Breast-conserving surgery (BCS) has also been a standard treatment for patients with early breast cancer. However, approximately 10% of patients with BCS develop ipsilateral breast tumor recurrence (IBTR), and mastectomy or resection of the recurrent tumor is generally performed. There are no specific guidelines available regarding staging and treatment of the regional lymph nodes. However, the reported risk of axillary lymph node metastasis among patients with local recurrence after breast surgery and a previous negative sentinel node biopsy of 26 % is too high to be ignored. Moreover, evaluation of the regional lymph node basins might be helpful to decide on the indication for adjuvant radiotherapy and systemic treatment. For these reasons it seems sensible to perform a regional lymph node staging procedure in patients with locally recurrent breast cancer. In general practice, this would mean that patients with recurrent breast cancer and a previous negative sentinel node biopsy would receive an axillary lymph node dissection (ALND) and that patients with a previous ALND would receive no additional axillary staging. Lymphatic drainage after previous breast surgery and/or radiotherapy would be altered and it remains questionable whether SLNB at the time of surgery for IBTR (second SLNB) is technically feasible and ALND can safely be omitted. In this study, investigators propose for all patients the realization of SLNB procedure and systematically ALND whatever the results of SLNB analysis, only on patients previously treated with breast conservative surgery. The aim of this study is to evaluate on a homogeneous prospective multicentric cohort of patients the feasibility and the accuracy of a second SLNB procedure for IBTR.
This study is investigational and is not designed to treat cancer. In other words, the study drug, entinostat, is not being given to treat cancer. Instead, the study team is looking at the effects of entinostat on tumor tissue for research purposes only. Approximately 246,660 cases of breast cancer were diagnosed in the United States in 2016. Its detection and treatment remains a major concern in women's healthcare. In particular, TNBC accounts for approximately 15-20% of all breast cancers. Research into treatment for breast cancer relies more and more on understanding how the cancer cells act when they are exposed to an anti-cancer drug. How most cancer cells act when exposed to anti-cancer drugs and which patients as a result may benefit the most from these drugs is not well known. Additional studies are required to determine the cells' reactions. The purpose of part 1 of this study is to better understand how TNBC tumors react to one particular cancer drug, entinostat. Entinostat is currently being studied across multiple clinical trials for the treatment of breast cancer, other solid tumors and blood cancers. Entinostat is investigational and has not yet been FDA approved for the treatment of cancer. Studies have shown that a good way to determine how cancer acts when exposed to anti-cancer drugs is a short-term preoperative window study. In this type of study, subjects receive a study drug a couple of days before surgery. Leftover tissue from surgery is then used to determine some of the effects that a study drug may have on the tumor. In this study, subjects will receive two doses of entinostat prior to undergoing planned surgery. Leftover tissue from this surgery will then be used to determine the effects entinostat has on tumor cells. For example, the study team will examine if the types of genes and proteins that the tumor expresses as a result of entinostat exposure increases or decreases the likelihood that the tumor will not continue to grow. A gene is a unit of DNA. Genes make up the chemical structure carrying your genetic information that may determine human characteristics (i.e., eye color, height and sex). This study will focus on discovering how entinostat affects a wide variety of genes in tumor cells.
The purpose of this project is to examine whether treatment with vandetanib has an effect on the tumor cells in breast cancer by examining tissue markers.
This research study is designed to look at the effects of the combination of vorinostat (Suberoylanilide Hydroxamic Acid or Zolinza) and tamoxifen on breast cancer tissue. The investigators will do this by comparing tissues from the original breast biopsy to tissues obtained after taking vorinostat and tamoxifen for 2 weeks.
The primary objective of this study is to identify the group of women with early stage breast cancer most likely to benefit from treatment with the selective progesterone receptor modulator (SPRM) mifepristone. This will be done by treating women briefly prior to planned surgery and examining the decrease in growth rate (measured by Ki-67 immunohistochemistry) in tumor samples taken before and after exposure to mifepristone.
