title: [Analysis of surgical treatment of primary lung cancer having M1 diseases].
abstract: The presence of distant metastasis is thought as systemic dissemination of disease. Patients with lung cancer in this category are not usually considered candidates for surgical resection of the primary and metastatic sites. The purpose of this study is to determine long-term survival and identify potential prognostic factors for surgical treatment to primary non-small cell lung cancer with distant metastasis. We conducted a retrospective analysis of the surgical outcome of 24 patients who were classified as having M1 disease. The 5-year survival rate was 34.6% in our facility. Among the 12 patients had N2 disease and a poor prognosis. Long-term survival can be achieved if the metastatic site is lung and there is no lymph node involvement, although differentiation of pulmonary metastasis and multiple primary lung cancer is commonly difficult.
