Abstract:
Objective:To analyze the risk factors of prognosis in patients with intracranial solitary fibrous tumor/hemangiopericytoma (SFT/HPC).Methods:The clinical data of 74 intracranial SFT/HPC patients underwent surgical treatment from January 2017 to January 2024 in Luhe Hospital, Capital Medical University and Sanbo Brain Hospital, Capital Medical University were retrospectively analyzed. The patients were followed up the prognosis (including recurrence, death and extracranial metastasis). Kaplan-Meier and log-rank tests were used to analyze the risk factors of prognosis in patients with intracranial SFT/HPC, and multivariate Cox analysis was used to analyze the independent risk factors of prognosis in patients with intracranial SFT/HPC.Results:Seventy-four patients with intracranial SFT/HPC were followed up for 3 to 80 months, averaging 52.5 months. Among them, there were 17 cases of recurrence, 6 cases of extracranial metastasis, and 12 cases of death. In patients with intracranial SFT/HPC, the results of the log-rank univariate analysis showed that the tumor location, resection extent, WHO pathological grade, and adjuvant radiotherapy were risk factors of recurrence ( P<0.01); the tumor location, WHO pathological grade and extracranial metastasis were risk factors of death ( P<0.05 or <0.01); and the age, WHO pathological grade and Ki67 were risk factors of extracranial metastasis ( P<0.05 or <0.01). In patients with intracranial SFT/HPC, multivariate Cox regression analysis result showed that the subtotal resection and non-postoperative radiation therapy were independent risk factors of recurrence ( HR = 0.377 and 0.315, 95% CI 0.148 to 0.932 and 0.164 to 2.221, P<0.01 and <0.05); the WHO pathological grade Ⅲ and extracranial metastasis were independent risk factors of death ( HR = 3.657 and 1.657, 95% CI 0.964 to 7.147 and 0.964 to 2.848, P<0.01); the WHO pathological grade Ⅲ was an independent risk factor of extracranial metastasis ( HR = 1.657, 95% CI 0.964 to 2.848, P<0.01). Conclusions:Patients with intracranial SFT/HPC who undergo subtotal resection and non-postoperative radiation therapy are more prone to recurrence, WHO pathological grade Ⅲ patients are more likely to develop extracranial metastases, and extracranial metastases patients have shorter survival. For intracranial SFT/HPC patients with pathologically high-grade, SFT/HPC, it is necessary to increase the frequency of follow-ups and be alert for extracranial metastasis.
