Spacer balloons, otherwise known as “cavity evaluation devices” (CEDs), are frequently placed intraoperatively at the time of lumpectomy to facilitate accelerated partial breast irradiation (PBI). CEDs provide a pathway to the excision cavity, preserve cavity shape/volume, and simplify delayed insertion of a single-entry brachytherapy device such as MammoSite, Contura or SAVI.1 Despite these intentions, significant issues have become apparent with widespread utilization of CEDs:
1.
The unavailability of a pathology report documenting PBI eligibility;
2.
The possible necessity for re-excision after the CED has been placed;
3.
The tendency of some surgeons to seek multidisciplinary consultation after the lumpectomy with the CED in place;
4.
Increased risk of infection;
5.
Barrier to entry to the phase III randomized prospective clinical trial NSABP–B39/RTOG 0413;
6.
With improved, user-friendly techniques of catheter/device insertion, the need for a CED is diminished;
7.
Patient disappointment.
