Pulmonary laser-assisted metastasectomy is associated with prolonged survival in patients with colorectal cancer.

Background: Pulmonary metastases develop in 10-15% of patients with colorectal cancer. Surgical metastasectomy currently provides the only hope for a cure for these patients. The aim of this study was to analyze the expanding role of pulmonary metastasectomy in the context of laser-assisted surgery (LAS) non-laser-assisted surgery (NLAS).
