Efficacy and prognostic analysis on surgical resection of pulmonary metastasis from colorectal cancer / 中华胃肠外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To elucidate the efficacy and probable prognostic factors of surgical resection of pulmonary metastasis from colorectal cancer.</p><p><b>METHODS</b>Clinical data and outcomes of 35 colorectal patients with pulmonary metastasis undergone pulmonary metastasectomy were analyzed retrospectively.</p><p><b>RESULTS</b>Median follow-up time was 48.0 months. The median overall survival time was 36.0 months. Five-year survival rate was 33.0%. Nineteen patients died of tumor progression. Sixteen patients were survival including survival with tumor (10 cases) and without tumor (6 cases). One patient was still alive without tumor for 164 months. Univariate analysis revealed that disease free interval (DFI) was a prognostic risk factor, while gender, age, primary tumor site, pulmonary metastasis size and location, surgical procedure, pre-surgical CEA level, re-metastasectomy did not show influence on the survival time after pulmonary metastasectomy.</p><p><b>CONCLUSIONS</b>For some selected patients with indication, pulmonary metastasectomy may be a potential curative method. DFI may be associated with the prognosis after pulmonary metastasectomy.</p>
