Abstract

Aim:

This study's aim is to define the clinicopathological and surgical outcomes, clinical courses, and results of long-term follow-up of cases that underwent surgical treatment for solitary fibrous tumors of the pleura (SFTp).

Subjects and Methods:

Clinical and long-term follow-up records of 16 consecutive patients who had surgery for SFTp between 2006 and 2016 were reviewed in the retrospective chart review. There were nine males (56%) and seven (44%) females with an average age of 60.5 ± 17.1 (range 30-87 years). Etiological factors, diagnostic procedures, clinical and surgical outcomes, 5-year overall survival (OS), and disease-free survival (DFS) in these patients were researched.

Results:

There was no remarkable common etiological factor. Nine of the cases were asymptomatic. Other symptoms were chest pain, dyspnea, cough and hypertrophic osteoarthropathy, respectively. Thoracotomy for the removal of pleural mass was carried out in 15 (94%) cases. Additional resection procedures included the chest wall resection in two cases and lobectomy in two. Video-assisted thoracoscopic surgery (VATS) resection was performed in one (6%) case. Complete surgical excision was performed in 74% of cases. Nineteen percent of cases were malignant SFTp (mSFTp). One of the mSFTp cases died in the 19th month after the diagnosis. The mean follow-up time was 50.6 ± 34.2 months (2--114 months). Mean survival of mSFTp patients was 40.6 ± 19.08 months (19--55 months) and that for benign SFTp (bSFTp) was 52.9 ± 37.05 months (2--114 months). Five-year OS--DFS were 93.5% and 74%, respectively.

Conclusion:

SFTp is an uncommon benign neoplasm but it can have malignant features. Even in the case of recurrence, the main treatment is total surgical excision. Oncologic treatments can be tried in unresectable and metastatic cases. VATS can be used in surgical total excision for small diameter and appropriate tumors. Understanding the nature of these tumors, immunohistochemical, and genetic studies may be a guide in future.
