IORT Following Breast Conserving Surgery for Early Stage Breast Cancer Registry

Purpose

This is a prospective, registry trial which will enroll women aged 65 and above with early stage, low risk breast cancer who will be treated with partial mastectomy and intraoperative radiation therapy (IORT). The primary aim is to determine the 5-year risk of in-breast tumor recurrence. Secondary aims include identification of acute- and late-toxicity, cosmetic result, disease-free survival and overall survival.

ArmDescriptionAssigned Intervention
IORT All patients will undergo a partial mastectomy with sentinel lymph node biopsy with the goal of achieving a margin-negative resection while maintaining good cosmetic outcome. Immediately following partial mastectomy and frozen section evaluation of the sentinel lymph nodes, IORT is to be delivered. Intraoperative radiation therapy will involve 50 kV xrays to a dose of 20 Gy during breast conserving surgery. After surgery, patients are followed based on the standard schedule determined by their surgeon for 5 years.
  • Radiation: IORT
    Intraoperative radiation therapy with INTRABEAM system to a dose of 20 Gy
