Q: If there is only a 1.4 cm invasive and intraductal mammary carcinoma of low nuclear grade, could IORT (intraoperative radiation therapy) be used during surgery?
Ideal candidates for intraoperative radiotherapy (IORT) at the time of breast conservation surgery are women over 60 with ductal carcinoma under 3 cm in diameter without involved lymph nodes. Women between 50 and 60 who have low grade tumors and other good prognostic factors may be candidates as well. For women under 50, we tend to use IORT as a boost to the tumor bed, but then follow that with a shortened course of whole breast radiation.
Every individual’s case is different, so it’s important that doctors and patients communicate with each other to ensure the best possible option is being offered to the patient.
