To evaluate baseline and change in the expression levels of progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), epidermal growth factor receptor (EGFR), cytokeratin 5/6 (CK5/6), and aromatase before and after treatment with entinostat and anastrozole/tamoxifen.\n\nII. To assess baseline and change in tumor tissue histone H3 and H4 acetylation before and after treatment with entinostat and anastrozole/tamoxifen.\n\nIII. To assess the clinical and pathological response to preoperative combination of entinostat and anastrozole/tamoxifen in TNBC.\n\nTERTIARY OBJECTIVES:\n\nI. To correlate the levels of histone H3 and H4 acetylation in tumors with the changes in Ki67 and ER.\n\nII. To evaluate baseline and change in gene methylation silencing and expression of candidate genes in tissues and in circulating DNA, including estrogen receptor (ER)-alpha, ER-beta, RAR-beta, cyclin D2, Twist, RASSF1A, and HIN-1.\n\nIII. To correlate entinostat trough concentrations with histone H3 and H4 acetylation in tumors as well as the change in Ki67 and ER.\n\nIV. To evaluate baseline and change in the global gene expression profile before and after treatment with entinostat and anastrozole/tamoxifen.\n\nOUTLINE: This is a multicenter, pilot study followed by a phase II study.\n\nPatients receive entinostat orally (PO) once daily on days 1, 8, 15, 22, and 29 and anastrozole PO once daily on days 4-29. Patients then undergo mastectomy or lumpectomy.\n\nTumor tissue samples are collected at baseline or from original diagnosis, and during surgery for correlative studies by IHC and RT-PCR. Blood samples are also collected at baseline, on days 1 and 15, and during surgery for correlative studies.\n\nAfter completion of study therapy, patients are followed up for 30 days.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria\n\n* Female greater than or equal to 18 years.\n* Eastern Cooperative Oncology Group (ECOG) performance status \\<2 (see Appendix A).\n* Histologically confirmed adenocarcinoma of the breast.\n* Evidence of hormone insensitivity (ER and PR negative) of primary tumor tissue.
