[Surgical treatment and prognosis of pulmonary metastasis].
OBJECTIVE
To study the surgical treatment and the prognosis of pulmonary metastasis.


METHODS
59 patients in the operative group and 36 patients in the control group were included. Their clinical data were collected by follow-up investigation and the prognosis was analyzed by stepwise regression.


RESULTS
The median survival time was 20.2 (operative group) and 10.0 (control group) months. The 1, 3 and 5-year survival rates in the two groups were 70%, 39%, 34% (operative group) and 28%, 8%, 0% (control group) respectively. The 5-year survival rate of patients with disease-free interval (DFI) < 1 year was 21%, while that of patients with DFI >/= 1 year was 40%.


CONCLUSIONS
Resection of pulmonary metastasis should be considered if indicated. DFI is an important prognostic factor for pulmonary metastasis.
