    Abstract:
    UNLABELLED: The objective of the present study was to retrospectively analyze a cohort of patients who underwent surgery for colorectal cancer pulmonary metastases during a 12-year period. PATIENTS AND METHODS: The sample included 75 patients who were monitored in terms of overall survival (OS) and disease-free interval (DFI) in relation to patient's age, preoperative values of biomarkers, type of surgery, number and size of metastases, occurrence of complications and length of hospitalisation. RESULTS: A total of 95 surgical interventions were performed and 133 metastases were removed. Out of these, 28% of patients were free of any signs of relapse or disease progression for 5 years after metastasectomy. Those with two or more metastases are 2.3-times more at risk of disease progression. Tissue polypeptide specific antigen (TPS) values above the 140 IU/l cut-off point increase the risk of progression 3.9-times. The five-year survival rate among the group was 45%. Patients with 2 or more metastases are 2.7-times more at risk of death. TPS values above the 140 IU/l cut-off increase the risk of death 5.5 times, and carbohydrate antigen CA19-9 values above the 28 IU/ml cut-off point increase the risk of death by 3.2 times. CONCLUSION: The number of metastases and the preoperative TPS values are decisive prognostic factors influencing both OS and DFI.
