[Analysis of the Choice of Operation Mode and Prognosis Factors of Patients with Tumors of the Lung Metastasis].
BACKGROUND
Concept of treatment for pulmonary metastatic tumor has been changed. The aim of this study is to analysis of the choice of operation mode and prognosis factors of patients with tumors of the lung metastasis.


METHODS
The clinical data of 57 patients with pulmonary metastases who underwent operations from January 2006 to December 2009 were retrospectively analyzed. Difference of conventional open thoracic surgery and thoracoscope surgery was compared. The relationship between gender, age, type of surgery, disease-free interval (DFI), the number of metastatic tumor, the size of tumor, chemotherapy and prognosis was explored.


RESULTS
Among the patients, there was no perioperative mortality. Postoperative 1-, 3-, 5-year survival rates were 81.3%, 46.5% and 29.2%, the median survival time was 33.8 months. Multivariate analysis showed that DFI, the number and diameter of metastasis tumor were independent prognostic factors.


CONCLUSIONS
Reasonable choice of surgical treatment can improve the survival of pulmonary metastatic tumor patient. Thoracoscopic surgery method is preferred. Operation effect of patients with tumor diameter less than 4 cm in solitary pulmonary metastasis has better effect.
