BRE-04: Window of Opportunity Trial of Preoperative Low Dose Azacitidine in High-Risk Early Stage Breast Cancer
Study Details
Study Description
Brief Summary
To determine the effect of low dose azacitidine therapy on tumor infiltrating lymphocytes (TILs) in primary tumors from patients with high-risk early stage breast cancer, paired t-tests will be first used to compare TIL count in pre- and post-treatment specimens.

Detailed Description
To determine the effect of low dose azacitidine therapy on tumor infiltrating lymphocytes (TILs) in primary tumors from patients with high-risk early stage breast cancer, paired t-tests will be first used to compare TIL count in pre- and post-treatment specimens. Median TIL counts will be compared between the pre- and post-treatment specimens with the Wilcoxon signed-rank test if TIL count does not follow normal distribution. General linear model (GLM) or kruskal wallis test will be used in the multivariate analyses to estimate the effect of low dose azacitidine therapy on TILs after adjusting for other clinical factors and patients characteristics, including the heterogeneity of tumors.
