Summary

Backround:
Colorectal carcinoma has the third highest incidence of all tumor diseases in the world. In the long term, Slovak republic is among countries with highest occurrence of this disease. About 25% of patients have distant metastases at the time of diagnosis, and about 50% of patients progress. The first possibility of colorectal carcinoma lung metastases treatment is metastasectomy which may have a curative character.

Materials and Methods:
In this paper, the authors retrospectively evaluated 50 patients who had undergone surgical treatment to establish the diagnosis of colorectal carcinoma lung metastases at the Clinic of thoracic surgery of JLF UK and UH Martin between 2003 and 2014.

Results:
Altogether, 27 men and 23 women were operated (average age: 62 and 61 years). 52% of patients had solitary metastasis.We chose thoracotomy as a surgical access for majority of the surgeries (76%), and the most common type of surgical procedure was a wedge resection (74%). 3-year survival of patients after complete metastasectomy was 55.5%, and 5-year survival was 31.8% with a median survival of 42 months. We did not record any statistically significant influence of number of metastases (p = 0.3297) and length of disease-free interval (p = 0.4423) on the long-term survival, but we confirmed a significant difference of survival in different prognostic groups according to the International registry of lung metastases (p = 0.049).

Conclusion:
A surgical removal of colorectal carcinoma lung metastases in selected patients is an important curative modality that might prolongsurvival, improve the prognosis and at the same time have minimum complications. The results show that the strongest predicative indicator of prognosis is incorporation of the patients to the prognostic groups determined by the International Registry of Lung Metastases
