Clinical Trial Summary

This study offers single fraction radiation treatment through partial breast irradiation in patients with early stage breast cancer after having a lumpectomy.


This study offers single fraction 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 a single higher dose 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.

Related Conditions & MeSH terms


Single 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

Type Measure Description Time frame Safety issue
Primary Toxicity levels of single fraction SBRT for partial breast irradiation assessed by CTCAE v4.0 To determine the safety of single fraction SBRT for patients with early stage breast cancer after a lumpectomy. Safety will be determined by CTCAE v4.0 and access toxicity, or lack of, experienced by patients enrolled in this study. 0-2 years
Secondary Toxicity of breast SBRT using CTCAE v4.0 To define the acute (<90 days) and late toxicity (>90 days) up to two years after breast SBRT (CTCAE 4) attributable to therapy. 0-2 years
Secondary Cosmetic outcome post-SBRT To determine patient and nurse assessed cosmetic outcome at 1, 6, 12, 18, 24, and 36 months post SBRT. Patient will give a verbal satisfaction rating of 1-Excellent, 2-Good, 3-Fair, or 4-Poor of their cosmetic appearance post-SBRT. Nurse will also give their overall rating of 1-Excellent, 2-Good, 3-Fair, or 4-Poor based off of their examination of the cosmetic appearance post-SBRT. 0-2 years
