I. Compare molecular analysis of pre- and post-treatment tissue samples of breast cancers of patients treated with 14-28 days of oral retinoid X receptor (RXR)-selective retinoid 9cUAB30 (9 cUAB30) will demonstrate significantly reduced proliferation.
I. Determine if 14-28 days of oral RXR-selective 9c-UAB30 treatment increases apoptotic index, as measured by cleaved caspase 3 assay.
II. Examine the differences in gene expression from baseline to post-exposure breast cancer samples using a custom gene panel from Nanostring Technologies.
III. To examine if the maximum concentration (Cmax) and safety of 9cUAB30 in the first 5 participants is affected by reducing the number of capsules at the 240 mg dose level.
IV. To examine the Cmax of all participants at baseline and on the day of surgery.
V. Determine if treatment with 2-4 weeks of 9cUAB30 prior to surgery will increase gene expression of type I immune cells in the tumor immune environment of all participants except the first 5.
VI. Assess the overall safety of 9cUAB30 in comparison with known retinoid toxicity.
I. Determine if treatment with 2-4 weeks of 9cUAB30 prior to surgery will increase activated type I dendritic cells in peripheral blood.
Patients receive retinoid 9cUAB30 orally (PO) once daily (QD) for 14 to 28 days. Patients then undergo tumor resection surgery.
After completion of study treatment, patients are followed up at 7 days and 4-5 weeks.

Experimental: Treatment (retinoid 9cUAB30)

Drug: Retinoid 9cUAB30
Procedure: Therapeutic Conventional Surgery
Undergo tumor resection surgery
- Absolute change in Ki-67 expression in breast epithelial cells of patients treated with 9cUAB30 [ Time Frame: Baseline up to 28 days (post-exposure) ]Will be assessed by immunohistochemistry. The baseline, post-exposure, absolute change in Ki-67, and difference in absolute change between the treated and matched controls will all be summarized with descriptive statistics. The primary analysis will compare the difference in absolute change in Ki-67 between treatment and matched "control" group using a one-tailed paired t-test or Wilcoxon signed-rank test, as appropriate, at a significance level of 0.05.
- Change in apoptosis in breast epithelial cells of patients treated with 9cUAB30 [ Time Frame: Baseline up to 28 days (post-exposure) ]Will be assessed by caspase 3 assays and immunohistochemistry. Change between the treated and matched controls will be summarized with descriptive statistics. Difference in apoptosis will be compared between treatment and matched "control" group using a one-tailed paired t-test or Wilcoxon signed-rank test, as appropriate, at a significance level of 0.05.
- Change in gene expression of breast cancer samples using a custom gene panel from Nanostring Technologies [ Time Frame: Baseline up to 28 days (post-exposure) ]Change in gene expression will be summarized with descriptive statistics.
- Change in maximum concentration (Cmax) [ Time Frame: Baseline up to day 1 ]Will be tested by a one-sided one-sample student t-test.
- Incidence of observed adverse events [ Time Frame: Up to 28 days ]Will be graded according to Common Terminology Criteria for Adverse Events version 4.0. Will be compared to know retinoid toxicity. These will be described in descriptive statistics and analyzed.
