Unlike lung metastases of @entity242 , primary @entity358 is very rare. We analyzed 7 primary @entity242 treated surgically in Hospital Universitario La Paz, Madrid, Spain between 1985 and 2001. Preoperative histologic diagnosis was correct for 2 @entity1 . Surgery was performed in all 7 @entity1 . Resection was extended to the left atrium in 1 @entity1 , to the chest wall in another, and the parietal pleura were removed from 2 others. Surgical resection was considered complete in 6 cases. Histology revealed 4 cases of @entity1418 , 1 @entity5426 , 1 @entity421 , and 1 undifferentiated @entity242 . Enlarged lymph nodes removed during surgery were @entity5 free. Three @entity1 received complementary treatment. The 3 longest-surviving @entity1 were treated with surgery alone; at the end of the study, these @entity1 remained alive 16, 9, and 4 years after surgery. One @entity1 has a recurrent @entity5 in a single lung. Three @entity1 died within 1 year and another died 24 months after surgery. In conclusion, surgical treatment of primary @entity358 achieve good survival.
