Outcomes and Prognostic Factors Following Surgical Treatment of Pulmonary Metastases from Colorectal Carcinoma

Background/Aim: The lungs are the second most common site of cancer dissemination. The aim of this study was to analyze a cohort of patients operated for pulmonary metastases from colorectal carcinoma over a period of 18 years. Patients and Methods: In a group of 104 patients, relations were sought between overall survival or disease free survival and preoperative levels of selected biomarkers, number of metastases and the condition of the intrathoracic lymphatic nodes. Median observation period was 63 months. Results: The 5-year survival rate was 54.3%. Risk of disease progression and risk of death increases in case of occurrence of 2 or more metastases, affection of intrathoracic lymph nodes and levels of CA 19-9, TPS or CEA above cut-off value. Conclusion: Prognostic factors that determine overall survival as well as disease-free survival are the number of metastases, the condition of intrathoracic lymphatic nodes and the preoperative levels of biomarkers.
