Tamoxifen Citrate or Letrozole with or without Palbociclib in Treating Patients with Stage I-III Invasive Breast Cancer before Surgery
This phase II clinical trial studies how well tamoxifen citrate or letrozole with or without palbociclib work in treating patients with stage I-III invasive breast cancer before surgery. Antihormone therapies, such as tamoxifen citrate and letrozole, may lessen the amount of estrogen made by the body. Palbociclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether giving tamoxifen citrate or letrozole with or without palbociclib may work better in treating patients with stage I-III invasive breast cancer.
