Solitary fibrous tumor of the pleura: surgery and clinical course in 18 cases.

摘要

Solitary fibrous tumors of the pleura are very rare neoplasms that can sometimes present with malignant features. Between 1984 and 2007, 18 cases were treated in our institution. There were 7 men and 11 women, with a median age of 56 years (range, 33-77 years). All patients underwent surgical treatment. Except for one case with hemangiopericytic features, all tumors were histologically the fibrous type of pleural mesothelioma. Resections were radical and there were no recurrences. There was no perioperative mortality. The outcome was excellent, and all patients have been followed up continuously. Survival rates at 3, 5, and 10 years were calculated as 86.7%, 75%, and 66.7%. One patient died after 18 months (malignant type of solitary fibrous tumor), and 2 died of unrelated disease after 24 and 53 months. Surgery is the treatment of choice, and careful long-term clinical follow-up is required.
