External Beam Partial Breast Irradiation Most Cost-effective Treatment

External beam partial breast irradiation (EB-PBI) is the most cost-effective method for treating postmenopausal women with early-stage breast cancer based on utilities, recurrence risks and costs when compared to whole breast radiotherapy (WBRT) and brachytherapy partial breast irradiation (brachy-PBI), according to a study in the June 1 issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Radiation Oncology (ASTRO).

PBI is a newer form of radiation therapy for breast cancer where only part of the breast is treated twice a day for four to five days. Radiation oncologists have been studying different methods to deliver the radiation to the tumor. EB-PBI uses high-energy external X-rays to deliver radiation to the breast after a lumpectomy and brachy-PBI delivers radiation through either implanted needles or a small sphere placed into the post-lumpectomy cavity in the breast.
