Surgical treatment outcomes of solitary fibrous tumors in the head and neck: A retrospective study
Résumé
Purpose
The aim of this study was to better characterize head and neck solitary fibrous tumors (SFTs) and to evaluate surgical treatment.
Materials and methods
This retrospective study included all patients who presented with head and neck SFTs between 2003 and 2021 in four university hospitals. Clinical, radiological, and histological information and data regarding the treatments performed were collected. The risk of locoregional and distant metastases was calculated, and for orbital SFTs a specific classification was used.
Results
Overall, 34 patients were included. The majority of the SFTs were found in the oral cavity (n = 10), followed by the neck region (n = 8). The mean time to recurrence was 67.4 months. All patients underwent primary surgical resection. Recurrence was observed in five patients with a low risk of locoregional recurrence and distant metastasis.
Conclusion
The treatment of choice is complete resection. Recurrence seems to be highly correlated with positive surgical margins. The safety margin should be increased when removing the lesion, and long-term follow-up should be performed.
