Executive summary

A review specifically for PBT partial breast irradiation. This review found that tumor control with PT is excellent, and the toxicities associated with PT PBI are minimal, with cosmetic outcomes improved by the increased recognition to utilize multi-field treatment plans. This review suggested that a subset of patients may benefit most from the use of PT for PBI, such as those with large tumors, limited breast volume, and medial tumor location. In addition, unfavorable anatomy, connective tissue disorders, and prior irradiation may also be considered more strongly for the use of PT for PBI.
