Brief Summary

Post Marketing Surveillance (PMS) study. Up to 93 patients undergoing breast conserving surgery will be enrolled in a prospective, single center, non-randomized controlled study, and a corresponding number of historical patients that underwent BCS will serve as the historical control group, accounting for a 1:1 ratio. All study patients and the patients in the historical control group will be required to meet the study eligibility criteria.

BCS will be performed with the routine standard of care (SOC), including intra-operative methods used to improve margin assessment. In addition to SOC process, the main specimen from patients found eligible will be scanned in the ClearCoast™ system. The surgeon will utilize the information from the ClearCoast images in his margin assessments evaluation which includes the diffusion at the surface of a particular aspect (suggesting irregular tissue at the specimen's surface), and decide whether to excise additional tissue. The decision-making process including MR images interpretation and the surgical decisions will be evaluated and documented. Following procedure, routine histopathology examination will be performed accompanied by the ClearCoast optical and parametric maps.

This study is a controlled design, in which subjects previously having undergone BCS by the same surgeons, will serve as the historical control group, comparing the following endpoints:

• Complete surgical re-excision rate
• Total excised breast tissue volume

The study Control group is composed of historical data from patients previously undergone BCS, under the same site SOC surgical practice, practicing surgeons, and study eligible criteria. This allows reducing inter-group variability and bias.

A device operator trained by ClearCut Medical will operate the device throughout the study.

Conditions

Breast Cancer

Study Design

• Observational Model Type: COHORT
• Study Time Perspective: PROSPECTIVE

Study Groups

Treatment Group

The removed specimen (as part of BCS) is scanned with the ClearCoast MR System.

ClearCoast MR System

Intervention Type: DEVICE

The removed specimen is scanned using the ClearCoast MR System.

Historical Group

Historical data of patients undergone BCS, under the same eligibility criteria and performed by the same study surgeons, thus minimizing inter-groups and inter-surgeon variability and bias, will serve as a control group for the comparison of the complete resection rate.

No interventions assigned to this group
