Accelerated Partial Breast Irradiation before Surgery for the Treatment of Early Stage Breast Cancer

Trial Status: active

This clinical trial studies the side effects of accelerated partial breast irradiation (APBI) and how well it works in treating patients with breast cancer has not spread beyond the breast and the axillary (armpit area) lymph nodes (early stage). Radiation therapy is a treatment for cancer and some other diseases. It uses high-energy rays (similar to X-rays) to damage and kill tumor cells, while trying to protect the healthy cells around them. The standard of care for early stage breast cancer is delivering radiation treatment to the whole breast after surgery followed by a boost (additional radiation) to the tumor bed, which is the area where the tumor used to be. APBI is a type of radiation therapy given only to the part of the breast that has cancer in it. Accelerated partial-breast irradiation gives a higher dose over a shorter time than is given in standard whole-breast radiation therapy. By giving APBI prior to surgery, when doctors can still visualize the tumor, doctors may be able to target the tumor better and minimize the radiation that the normal breast tissue would receive. By doing so, doctors may achieve better cosmetic outcomes and possibly better tumor control.
