Survival benefit of metastasectomy in colorectal cancer with pulmonary metastasis: a population-based, propensity score matched study

Background: The survival benefits of pulmonary metastasectomy (PM) in colorectal cancer (CRC) patients with pulmonary metastasis remain controversial. This study aimed to assess the survival effect of PM on CRC patients with pulmonary metastasis. Methods: Data from CRC patients with pulmonary metastasis were collected from the Surveillance, Epidemiology, and End Results database between 2010 and 2020. A 1:1 propensity score matching (PSM) analysis was employed to minimize heterogeneity between the groups. Kaplan-Meier analysis was performed to evaluate the overall survival (OS) of CRC patients with pulmonary metastasis who underwent PM. Results: < 0.01). Conclusion: PM prolongs the survival of CRC patients with pulmonary metastasis.
