IntraOperative Electron Radiation Therapy (IOeRT) is a groundbreaking international research project which is studying the use of IOeRT in the treatment of breast cancer. This project is funded in part by a $2.4 million grant from the Leona M. and Harry B. Helmsley Charitable Trust.

IOeRT is a high-dose radiation “boost” which shortens the course of post-surgery external-beam radiation treatments by weeks, from six weeks to three weeks.  IOeRT delivers a single targeted dose of radiation directly to a tumor site during surgery. While still in the research stages for breast cancer, IOeRT has already become standard treatment for certain types of cancer, such as advanced pelvic and abdominal tumors, sarcoma and colorectal cancers.

Who qualifies for this study?

  • Certain women with early-stage breast cancer
  • Women who opt for lumpectomy, or breast-conserving surgery

Benefits of participating in this study

  • A shortened time of post-surgery radiation treatments from six weeks to three weeks
  • More women, especially in rural areas, may be able to opt for breast-conserving surgery instead of mastectomy due to the shortened radiation treatment time
  • This study is determining whether outcomes are just as high or higher than six weeks of external beam radiation post-surgery
  • The opportunity to advance the science of medicine, and help other women in the future benefit from cutting-edge technology
