Descriptive Information
Brief Title  ICMJE Single Dose Ablative Radiation Treatment for Early-Stage Breast Cancer
Official Title  ICMJE Single Dose Ablative Preoperative Radiation Treatment for Early-Stage Breast Cancer in Elderly Patients
Brief Summary The purpose of the study is to investigate the feasibility of a preoperative, single dose, ablative partial breast radiation treatment in patients with early-stage breast cancer.
Detailed Description

A total of twenty-five patients will be treated with a single dose preoperative ablative radiation treatment. After a vigilant follow-up with MRI, breast conserving surgery will be performed 6 months after the ablative radiation treatment. The total follow-up time is 10 years.

This study aims to present an ablative radiotherapy treatment approach that could resolve to some extent the disadvantages of current breast conserving treatment in elderly low-risk breast cancer patients who are currently not treated according to guidelines due to co-morbidity.
