Pulmonary Metastasectomy in Colorectal Cancer (PulMICC International)

Pulmonary metastasectomy in colorectal cancer (PulMiCC) is a randomized controlled trial. Patients with resected colorectal cancer found to have one or more pulmonary metastases are randomized to have a metastasectomy or not. Both arms include active monitoring. Patients considered possible candidates for pulmonary metastasectomy are asked to first give consent to be assessed according to protocol after which a decision to have or not have metastasectomy may be made. If there is uncertainty, patients are invited to consent to randomization, including minimization for known prognostic factors: the number of metastases, the interval since primary resection, carcinoembryonic antigen levels and the TNM stage of the primary cancer. The primary outcomes are survival and quality of life. The trial is open in England, and in Serbia and Italy as PulMiCC International.
