FES PET/CT in Predicting Response in Patients With Newly Diagnosed Metastatic Breast Cancer Receiving Endocrine Therapy

This phase II trial studies F-18 16 alpha-fluoroestradiol (FES) positron emission tomography (PET)/computed tomography (CT) in predicting response to endocrine therapy in patients with newly diagnosed breast cancer that has spread to other parts of the body. FES is a radioactive form of the hormone estrogen and may "light up" where cancer is in the body. Diagnostic procedures using FES, such as FES PET/CT, may help measure the FES and help doctors predict how well the cancer will respond to treatment.

Platinum in Treating Patients With Residual Triple-Negative Breast Cancer Following Neoadjuvant Chemotherapy

This randomized phase III trial studies how well cisplatin or carboplatin (platinum based chemotherapy) works compared to capecitabine in treating patients with remaining (residual) basal-like triple-negative breast cancer following chemotherapy after surgery (neoadjuvant). Drugs used in chemotherapy, such as cisplatin, carboplatin and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether cisplatin or carboplatin is more effective than capecitabine in treating patients with residual triple negative basal-like breast cancer.

Multicenter Trial for Eliminating Breast Cancer Surgery or Radiotherapy in Exceptional Responders to Neoadjuvant Systemic Therapy

This clinical trial studies eliminating surgery and/or radiation therapy in treating breast cancer patients. In HER2 positive and triple negative breast cancers, after systemic therapy, when image-guided biopsy shows no residual cancer, patients then receive standard breast radiotherapy with no surgery. In ER positive/HER2 negative breast cancers, after endocrine therapy and ablative radiotherapy, when image-guided biopsy shows no residual cancer, patients then receive standard endocrine therapy with no surgery. For patients who have HER2 positive and triple negative breast cancers and standard surgery, after systemic therapy, breast radiotherapy is being eliminated when the pathology from surgery shows no residual cancer.

Vaccine Therapy and Pembrolizumab in Treating Patients With Solid Tumors That Have Failed Prior Therapy

This phase I trial studies the side effects of vaccine therapy and pembrolizumab in treating patients with solid tumors that have spread to other places in the body and usually cannot be cured or controlled with treatment, that have failed prior therapy, and that cannot be removed by surgery. Vaccines made from a gene-modified virus may help the body build an effective immune response to kill tumor cells. Monoclonal antibodies, such as pembrolizumab, may block tumor growth in different ways by targeting certain cells. Giving vaccine therapy together with pembrolizumab may be a better treatment in patients with solid tumors.

Exemestane With or Without Entinostat in Treating Patients With Recurrent Hormone Receptor-Positive Breast Cancer That is Locally Advanced or Metastatic

This randomized phase III trial studies exemestane and entinostat to see how well they work compared to exemestane alone in treating patients with hormone receptor-positive breast cancer that has spread to nearby tissue or lymph nodes (locally advanced) or another place in the body (metastatic). Estrogen can cause the growth of breast cancer cells. Endocrine therapy using exemestane may fight breast cancer by lowering the amount of estrogen the body makes. Entinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether exemestane is more effective with or without entinostat in treating breast cancer.

Neoadjuvant Pembrolizumab + Decitabine Followed by Std Neoadj Chemo for Locally Advanced HER2- Breast Ca

This study is a 2-cohort, open-label, multicenter, phase 2 study of a short course of immunotherapy consisting of sequential decitabine followed by pembrolizumab administered prior to a standard neoadjuvant chemotherapy regimen for patients with locally advanced HER2-negative breast cancer. The primary efficacy objective is to determine if the immunotherapy increases the presence and percentage of tumor and/or stromal area of infiltrating lymphocytes prior to initiation of standard neoadjuvant chemotherapy. At enrollment, patients will be assigned to one of 2 cohorts based on hormone receptor status. * Cohort A - patients with HER2-negative, hormone receptor-negative breast cancer (defined as both ER and PgR with \< 10% positive staining on IHC) Note: before beginning standard neoadjuvant chemotherapy, patients in Cohort A may be reassigned to Cohort A2 to receive extended pembrolizumab as part of new standard neoadjuvant and postoperative adjuvant therapy. * Cohort B - patients with HER2-negative, hormone receptor-positive breast cancer (defined as either ER or PgR with ≥ 10% positive staining on IHC)

Pembrolizumab and Carboplatin in Treating Patients With Circulating Tumor Cells Positive Metastatic Breast Cancer

The purpose of the study is to evaluate the impact on progression-free survival (PFS) with the combination carboplatin - pembrolizumab in patients with CTC (circulating tumor cells) positive, HER2 negative metastatic breast cancer previously treated with anthracyclines and taxanes. Previous studies have indicated that recurrent breast cancers are more resistant to chemotherapy and maybe associated with a weak immune system. This study is investigating the use of an immune therapy drug, pembrolizumab, that has the ability to restore the capacity of controlling and killing cancer cells of an important component of your immune system called T-cells. Pembrolizumab has been found effective in other types of cancer and has already been approved by FDA for those indications, but the efficacy in breast cancer is still unknown. In this study, pembrolizumab will be combined with chemotherapy to increase the cancer cell killing. There is no control or placebo treatment in this study.
