Clinical Trial: Partial Breast Radiation Therapy in Treating Women Undergoing Breast Conservation Therapy for Early-Stage Breast Cancer
Study Status: Active, not recruiting
Recruit Status: Unknown status
Study Type: Interventional
Official Title: Accelerated Partial Breast Irradiation
Brief Summary:
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells.
PURPOSE: This clinical trial is studying the side effects of partial breast radiation therapy and how well it works in treating women undergoing breast conservation therapy for early-stage breast cancer.
Detailed Summary:
OBJECTIVES:
- To allow women undergoing breast conservation therapy for early-stage breast cancer to have access to accelerated partial breast irradiation therapy on a controlled trial.
- To capture prospective data on acute and late toxicity and disease recurrence in patients treated with this therapy.
- To summarize the institutional experience of these patients treated with this experimental therapy.
OUTLINE: Within 9 weeks after surgery, patients undergo accelerated partial breast irradiation (including conformal external-beam irradiation, interstitial brachytherapy, intracavitary brachytherapy, or proton beam irradiation) twice daily for 5 days (10 fractions).
After completion of study therapy, patients are followed every 3 to 6 months for at least 5 years and then annually thereafter.
Sponsor: University of Pennsylvania
Current Primary Outcome: Acute toxicity as assessed by NCI CTC at 1 week, 4 weeks, and 3 months after completion of study therapy
Original Primary Outcome: Same as current
Current Secondary Outcome:
- Late toxicity and cosmesis as assessed at or before 3 years from the start of radiotherapy and every 3 months during follow-up
- Site of disease recurrence (i.e., local, regional, or distant)
- Time to recurrence
- Time to locoregional recurrence
Original Secondary Outcome: Same as current
