Surgical Resection of Solitary Fibrous Tumors of the Pleura / 대한흉부외과학회지

ABSTRACT

BACKGROUND: Solitary fibrous tumors of the pleura (SFTP) is one of rare neoplasms that originated from submesothelial mesenchyme. Clinical course or extent of surgical resection is not well known. MATERIAL ANDMETHOD: We retrospectively reviewed all the clinical records of the patients who had undergone surgical resection of benign and malignant SFTP. RESULT: Twenty two (male : female 14 : 8) patients were enrolled and mean age was 50.2 (range 25~83). Number of symptomatic patients at the time of diagnosis was 13 (59%) and the most common symptom was dyspnea. Operative approach was carried out through thoracotomy (n=14) or video-assisted thoracic surgery (n=8). Mass excision was performed in 12 cases and en bloc resection including adjacent structure in 10 cases. In all cases complete resection was performed. There was no operative mortality. Malignant SFTP were 11 cases and benign SFTP 11 cases. Local recurrences (n=2) or distant metastasis (n=6) occurred only in malignant SFTP. CONCLUSION: Number of symptomatic patients, en bloc resection, and recurrence was more in malignant SFTP. Although complete surgical resection is known as treatment of choice for SFTP, further study should be performed about systemic therapeutic modalities pre- or postoperatively to control recurrence and metastasis.
