[Solitary fibrous tumor of pleural cavity].

INTRODUCTION

Solitary fibrous pleural tumor (SFT) is, in most cases, a benign tumor arising from mesenchymal cells. A malignant version of the tumor is rare and its histopathological evaluation is quite difficult. Usually, SFT affects visceral, as well as parietal pleura, most commonly in a form of a pedunculated tumor. The treatment is primarily surgical, with the aim to perform radical resection even in case of infiltrative growth. Adjuvant therapy is indicated in malignant varieties of the tumor, however, its outcome is uncertain. SFTs have fairly high relaps rates and their prognosis and the risk of relaps can be estimated based on morphological indicators and assessment of their biological characteristics.

AIM

Retrospective analysis of SFT group of patients, who were operated from 2006 to 2009.

SUBJECTS AND METHODS

The authors present a group of 11 patients with solitary fibrous pleural tumors, who were operated at the Ist Faculty Hospital Surgical Clinic of the LF UP (Medical Faculty of the Palacky University) in Olomouc from 2006 to 2009. The authors assessed the patient's age, size of the tumors, types of the procedures, biological characteristics of the tumors, duration of hospitalization and complication rates.

CONCLUSION

Solitary pleural tumors are fairly rare tumors arising from fibroblastic cells, Its biological characteristics is uncertain and, in some cases, is difficult to assess based on immunohistochemical, as well as morphological indicators. The treatment is surgical--removal of the tumor as far as the healthy tissue. Adjuvant therapy is indicated in malignant varieties of the tumor. SFT relaps rate is fairly high, depending on the tumor biological characteristics and its morphological features.
