passionate pursuit <strong>of</strong> PBI. This study, presented at the<br />

34 th Annual San Antonio Breast Cancer Symposium (December<br />

6–10, San Antonio, TX), reviewed the Medicare<br />

records <strong>of</strong> 130,535 patients who received treatment with<br />

brachytherapy-based PBI or standard WBI between 2001<br />

and 2007. 14 The authors reported that women receiving<br />

treatment with brachytherapy-based PBI were almost twice<br />

as likely to subsequently require a mastectomy, be hospital-<br />

WBI. One must note that this study is retrospective<br />

and covers a period in which new PBI brachytherapy techniques<br />

were just being introduced. Nonetheless, it is perhaps<br />

most prudent for practitioners to reserve PBI for the<br />

protocol setting, or to wait for longer-term results from<br />

randomized controlled trials.<br />
