ABSTRACT

BACKGROUND: Intracranial solitary fibrous tumour (iSFT) is an exceptional mesenchymal tumour with high recurrence rates. We aimed to analyse the clinical outcomes of newly diagnosed and recurrent iSFTs. METHODS: We carried out a French retrospective multicentre (n = 16) study of histologically proven iSFT cases. Univariate and multivariate Cox models were used to estimate the prognosis value of the age, location, size, WHO grade, and surgical extent on overall survival (OS), progression-free survival (PFS), and local recurrence-free survival (LRFS). RESULTS: Eighty-eight patients were included with a median age of 54.5 years. New iSFT cases were treated with gross tumour resection (GTR) (n = 75) or subtotal resection (STR) (n = 9) and postoperative radiotherapy (PORT) (n = 32, 57%). The median follow-up time was 7 years. The median OS, PFS, and LRFS were 13 years, 7 years, and 7 years, respectively. Forty-two patients experienced recurrence. Extracranial metastasis occurred in 16 patients. Median OS and PFS after the first recurrence were 6 years and 15.4 months, respectively. A higher histological grade was a prognosis factor for PFS (p = 0.04) and LRFS (p = 0.03). GTR influenced LRFS (p = 0.03). CONCLUSION: GTR provided benefits as a first treatment for iSFTs. However, approximately 40% of patients experienced relapse, which remains a challenging state.

ABSTRACT

BACKGROUND: One of the most challenging aspects of the surgical treatment of tuberculum sellae meningioma is to control the involvement of the inferomedial side of the optic nerve, which is not directly visualized by an ipsilateral approach and thus requires optic nerve mobilization. METHODS: Between 2003 and 2017, 21 consecutive patients were operated on using this approach. The surgical technique is described and the visual outcomes, resection and recurrence rates, and complications are analyzed. RESULTS: Twenty patients were included, with a median follow-up of 5.6 years. Regarding visual outcomes, among the 19 patients who had a visual impairment before surgery, 14 (74%) improved, 2 were stabilized (10%), and 2 (10%) showed a worsening of the most-compromised optic nerve and 1 (5%) of the less-compromised optic nerve. Gross total resection was achieved in 18 patients (90%) and 1 patient experienced recurrence 10 years after the initial surgery. CONCLUSIONS: This approach allowed lower mobilization of the compromised optic nerve, better preservation of the vascularization of the visual pathways, and direct access to the inferomedial side of the optic nerve.
