Abstract:
Objective To investigate appropriate diagnosis and treatment of solitary fibrous tumor of the pleura (SFTP).Methods Clinical and pathological data of ten patients treated in our hospital from 2002 to 2007 were reviewed. Results Our series consisted of three men and seven women. In two patients correct diagnosis was made before operation through ultrasonography-gnided core needle biopsy. All the patients were treated surgically including three resected by video-assisted thoracic surgery (VATS). Histopathologically, five tumors were malignant and the other five were benign. Immunohistochemical staining showed malignant SFTP (3/5) were less frequently positive for CD34 than benign group (5/5). Nestin was only detected in malignancies (2/5), which were negative for CD34. Except for one, all patients were followed-up for 6 to 35 months (mean 17.3 months). One patient experienced a recurrence and one died of brain metastasis. Conclusion Ultrasonography-guided core needle biopsy combined with immunohistochemical analysis is a safe and rapid method to provide a confirmatory diagnosis before surgery. For smaller, pedunculated tumors, VATS may be a bettor approach. Besides, we speculated CD34-negative and nestin-posifive might be a malignant marker for SFTP.
