Main objective

Scope: Diagnosis

The primary objective of the MONITOR-RCT is to demonstrate that in patients with metastatic breast cancer, response monitoring based on FDG-PET/CT is superior to response monitoring based on CT with respect to overall survival. The objective will be based on applying standardized response evaluation criteria, using an appropriate adaptation of the PERCIST criteria for FDG-PET/CT and the RECIST1.1 criteria for CT.

Secondary objectives 1

  1. Secondary objectives of the MONITOR-RCT are to demonstrate superiority with respect to the quality of life and time and exposure to treatment and to investigate the cost-effectiveness and the occurrence of adverse events.
