Background: The radioactive seed localization (RSL) is used in impalpable breast cancer
conservative surgery to assist the surgeon in accurately locating and excising the lesion
site. This study aims to present recommendations about the RSL program implementation
in health institutions. Methods: An extensive literature review was performed. It comprehends: the committee
responsible for implementation of the program actions; description of the necessary
multidisciplinary team; the radiological safety committee role; the facility licensing;
professionals training; material and instrumentation associated with the technique; and
seed tracking system. Results: The Program Implementation Committee must be formed by leaders from each
department. The committee assumes responsibility for evaluating the necessary processes
and presenting the schedule for program implementation. Since the procedure is classified
as a nuclear medicine procedure it requires licensing. The Professional Team Formation,
Education, and Training is a priority and simulation exercises are necessary. The
Materials and Instrumentation Associated with the Technique must be well-know by the
team and they should practice using radiation detectors. The seed must be always tracked,
from moment they are received to discard. An Inventory for Tracking Seeds is provided.
The Radiological Safety Aspects such as the ALARA principle are presented. A full
description for the Radiological Procedure for Placing the seeds, the surgical removal and
the Specimen Handling in Pathology focusing on how to locate the seed and retrieve them.
After removed, the seeds can be placed in storage to wait for full radioactive decay or be
returned to the manufacturer. Conclusions: Regular multidisciplinary team meetings during program development are
important to create a realistic timeline, having briefing meetings after the first 1-5 RSL
cases and having annual or biannual follow-up meetings to discuss any issues or incidents.
