Surgical resection improves survival in colorectal lung metastases.

A retrospective analysis of 2,976 patients with solitary colorectal lung metastases revealed that surgical resection significantly enhances survival rates. Specifically, patients who underwent surgery had a five-year survival rate of 42.7%, compared to 29.7% for radiation therapy and 23.9% for conservative management. Multivariate analysis confirmed that surgical intervention was linked to improved survival outcomes (hazard ratio: 0.68). These findings support surgical resection as a viable option for select patients post-colon cancer treatment.
