Intraoperative Radiation Therapy (IORT)

What is IORT?

A new and innovative radiation treatment that allows for a single dose of radiation that is designed to be a replacement or an adjunct to standard radiotherapy (whole breast or external beam radiation).

Standard radiation therapy vs IORT

Standard radiation therapy treats the whole breast after surgery. Usually, it takes 33 daily sessions to complete one cycle.

Intraoperative radiation therapy involves radiating only the surrounding tissue after the tumor has been removed. It is often done during surgery and consists of one session that takes approximately 30 minutes depending on the size of the cavity after lumpectomy.

Who can undergo IORT?

Your surgeon will assess the following criteria before determining eligibility.

  • Age
  • Tumor characteristics (size, location, histology type)
  • Extent of cancer

Advantages of IORT

  • It allows for breast conserving surgery (or lumpectomy) vs. total mastectomy
  • Lessened treatment time (1 session vs 33 sessions)
  • Better quality of life (lessened travel time, less side effects)
