Clinical registries. Collecting data, improving quality.

Clinical registries collect data on a specific population defined by a particular disease, condition or procedure. SIR Foundation encourages these endeavors as they support evidence-based research that can ultimately help improve quality and patient safety.

    Thermal ablation versus surgical resection of small-size colorectal liver metastases (COLLISION): an international, randomised, controlled, phase 3 non-inferiority trial

    (The Lancet) For patients with small-size colorectal liver metastases, growing evidence suggests thermal ablation to be associated with fewer adverse events and faster recovery than resection while also challenging resection in terms of local control and overall survival. This study assessed the potential non-inferiority of thermal ablation compared with surgical resection in patients with small-size resectable colorectal liver metastases.
