Suppression of Ovarian Function With Either Tamoxifen or Exemestane Compared With Tamoxifen Alone in Treating Premenopausal Women With Hormone-Responsive Breast Cancer

RATIONALE: Estrogen can stimulate the growth of breast tumor cells. Ovarian function suppression combined with hormone therapy using tamoxifen or exemestane may fight breast cancer by reducing the production of estrogen. It is not yet known whether suppression of ovarian function plus either tamoxifen or exemestane is more effective than tamoxifen alone in preventing the recurrence of hormone-responsive breast cancer. PURPOSE: This randomized phase III trial studies ovarian suppression with either tamoxifen or exemestane to see how well they work compared to tamoxifen alone in treating premenopausal women who have undergone surgery for hormone-responsive 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)

A Text-based Intervention in Improving Adherence to Hormone Therapy in Patients With Stage I-III Hormone Receptor Positive Breast Cancer

This trial studies how well a text-based intervention works in improving adherence to hormone therapy in patients with stage I-III hormone receptor positive breast cancer. Women often require long term therapy with adjuvant hormone therapy to prevent the cancer from returning and to improve overall survival. Side effects from hormone therapy may prevent some women from staying adherent to their medication therapy. A text-based intervention may provide educational information to breast cancer patients who are undergoing adjuvant hormone therapy.
