Study Summary

This phase II trial studies how well radiation therapy before surgery works in treating patients with hormone receptor positive, HER2 negative breast cancer. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.

Primary Outcome

With 20 patients, a 95% confidence interval for the mean difference between TIL measurements would extend 0.44\*s units from the mean (where "s" is the standard deviation of the TIL differences). If the differences are not normally distributed, researchers will report the median difference along with appropriate 95% confidence intervals. Appropriate graphs used to visualize the data.
