RAD 1802: A Pilot Trial of Five Fraction Stereotactic Body Radiotherapy for Early Stage Breast Cancer Patients Eligible for Post-Operative Accelerated Partial Breast Irradiation (APBI)
University of Alabama at Birmingham
Summary
This study offers 5 fractions of radiation treatment through partial breast irradiation in patients with early stage breast cancer after having a lumpectomy.
Description
This study offers 5 fractions stereotactic body radiotherapy for early stage breast cancer after patient undergoes a lumpectomy. The study aims to determine the safety and feasibility of delivering only 5 doses of radiation treatment rather than the longer schedule of treatments that is currently considered standard of care for breast cancer patients. Patients will be followed for 36 months (2 years) with follow-up appointments at 6, 12, 18, 24, and 36 months.

Interventions
- Radiation5 Fraction Stereotactic Body Radiation Therapy
Stereotactic body radiation therapy (SBRT) has gained favor in the treatment of select central nervous system, lung, and abdominal malignancies due to its ability to deliver highly conformal doses of radiotherapy while using sharp dose gradients to deliver comparatively lower doses to the surrounding normal tissue. Utilization of SBRT is more labor intensive than conventional fractionation and requires precise immobilization and localization techniques with daily image guidance with direct physician and physicist oversight for all treatments. While more labor intensive and often utilizing more advanced technologies, SBRT allows the advantage of reducing setup margins compared to conventionally fractionated treatment while being able to shorten overall treatment times due to the ability to safely dose escalate high risk areas
