Participant Flow
The study was conducted at 19 sites in the USA. All study investigators had related experience in low-risk breast cancer treatment, imaging, and pathology assessments and were trained to perform the cryoablation procedure. The recruitment period lasted from October 2014 to February 2019.
A total of 212 Subjects were screened for enrollment in the study; 3 were screen failures, and 3 subjects withdrew consent before the procedure; 206 were enrolled and treated. Based on the DSMB recommendation, 12 subjects were excluded from the study after completing the cryoablation procedure. Nine (9) were due to deviation from inclusion criteria, and three (3) were due to incomplete treatment, resulting in the per-protocol study population of 194 subjects.
