Trial Outcomes & Findings for PET/MR in Surgical Planning for Breast CA Treated With Neoadj Chemo (NCT NCT04149353)

NCT ID: NCT04149353

Last Updated: 2020-06-16

Results Overview

Primary endpoint is the determination of the potential for PET activity estimates to predict RCB score in comparison with that of dynamic contrast enhanced (DCE) MRI. Treatment response will be determined on final pathological evaluation of the resected specimens by way of the RCB score.

PRIMARY outcome

Timeframe: Time Frame: Changes in image measures will be assessed from baseline scans, prior to therapy, to post-treatment scans, taken six months after baseline. Pathology data will be obtained post-surgery.

Population: Single subject did not complete the second scan, so outcome measure could not be assessed.

SECONDARY outcome

Timeframe: Changes in image measures will be assessed from baseline scans, prior to therapy, to post-treatment scans, taken six months after baseline. Pathology data will be obtained post-surgery.

Population: Single subject did not complete the second scan, so outcome measure could not be assessed.

Quantitative image measures from PET and MR will be compiled and an optimal linear regression will be derived between the image metrics and the outcome measure from pathology, the RCB score. Prediction performance of the regression relation will be assessed using a leave-one-out cross-validation approach.
