Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The primary goal of this tissue collection protocol is to establish a framework for the acquisition and banking of biospecimen collected from men undergoing brachytherapy. Biopsies of the prostate is an invasive procedure; however, in this tissue collection protocol, biopsies are acquired intraoperatively while patients are prepped for brachytherapy seed placement, thus minimizing the inconvenience of the biopsy procedure for patients. The utility of these biopsies will provide a valuable resource for molecular assessments.
