The American Brachytherapy Society Consensus Statement for Accelerated Partial-Breast Irradiation

This is a clinical practice guideline on the use of accelerated partial-breast irradiation (APBI) as adjuvant radiation after breast-conserving surgery for patients with ductal carcinoma in situ and early-stage invasive breast cancer. The guideline provides recommendations regarding appropriate patient selection and techniques to deliver APBI. Patient selection criteria include age, tumour size, histology, estrogen receptor response, surgical margins, lymphovascular space invasion and nodal status. Efficacy and toxicity are considered with respect to recommendations for the appropriate and safe utilization of APBI.
